                                  supplement.

THE TRUST

The Depositor will establish a trust with respect to the certificates  under the
pooling  and  servicing  agreement  dated  as of  the  Cut-off  Date  among  the
Depositor,  the Servicer, the Master Servicer, the Securities  Administrator and
the Trustee.  There are twenty classes of certificates  representing  the trust.
SEE "DESCRIPTION OF THE CERTIFICATES" IN THIS PROSPECTUS SUPPLEMENT.

The  certificates  represent in the  aggregate the entire  beneficial  ownership
interest in the trust. In general,  distributions of interest and principal,  if
applicable, on the Offered Certificates will be made only from payments received
or  advanced  in respect of the  mortgage  loans and  payments  made by the Swap
Provider under the interest rate swap agreement.

THE MORTGAGE LOANS

References  to  percentages  of  the  mortgage  loans  under  this  section  are
calculated based on the aggregate  principal balance of the mortgage loans as of
the Cut-off Date.

The trust will contain 5,501 conventional, one- to four-family, first and second
lien,  fixed-rate  and  adjustable-rate   mortgage  loans  on  residential  real
properties (the "Mortgage Loans").

For purposes of calculating  interest and principal  distributions  on the Class
A-1A Certificates, Class A-1B Certificates and the Class A-2A, Class A-2B, Class
A-2C and Class A-2D Certificates  (collectively,  the "Class A-2  Certificates";
and together with the Class A-1A Certificates and Class A-1B  Certificates,  the
"Class A  Certificates"),  the Mortgage  Loans have been divided into three loan
groups,  designated  as the "Group IA  Mortgage  Loans",  the "Group IB Mortgage
Loans" and the "Group II Mortgage Loans." The Group IA Mortgage Loans consist of
first  lien,  fixed-rate  and  adjustable-rate  mortgage  loans  with  principal
balances at origination that conformed to Freddie Mac loan limits.  The Group IB
Mortgage Loans consist of first and second lien,  fixed-rate and adjustable-rate
mortgage loans with principal  balances at origination  that conformed to Fannie
Mae loan limits.  The Group II Mortgage  Loans consist of first and second lien,
fixed-rate  and  adjustable-rate  mortgage  loans  with  principal  balances  at
origination that may or may not have conformed to Freddie Mac or Fannie Mae loan
limits.

The Class A-1A Certificates  represent interests in the Group IA Mortgage Loans.
The Class A-1B Certificates  represent interests in the Group IB Mortgage Loans.
The Class A-2 Certificates  represent  interests in the Group II Mortgage Loans.
The Class M-1, Class M-2, Class M-3, Class M-4, Class M-5, Class M-6, Class M-7,
Class M-8, Class M-9, Class M-10 and Class M-11 Certificates (collectively,  the
"Mezzanine Certificates") represent interests in all of the Mortgage Loans.

The  Group IA  Mortgage  Loans  consist  of  2,241  mortgage  loans  and have an
aggregate  principal  balance of  approximately  $449,214,623  as of the Cut-off
Date. The

REMOVAL AND SUBSTITUTION OF A MORTGAGE LOAN

The Trustee will acknowledge the sale, transfer and assignment of the trust fund
to it by the  Depositor  and  receipt  of,  subject  to  further  review and the
exceptions,  the Mortgage  Loans.  If the Trustee has actual  knowledge that any
Mortgage  Loan is defective  on its face due to a breach of the  representations
and  warranties  with  respect  to that  Mortgage  Loan made in the  transaction
agreements,  the Trustee shall promptly  notify the Sponsor of such defect.  The
Sponsor must then  correct or cure any such defect  within 90 days from the date
of notice from the Trustee of the defect and if the Sponsor  fails to correct or
cure such defect  within such period and such defect  materially  and  adversely
affects the interests of the  Certificateholders  in the related  Mortgage Loan,
the Sponsor  will,  in  accordance  with the terms of the pooling and  servicing
agreement,  within 90 days of the date of notice,  provide  the  Trustee  with a
substitute  Mortgage  Loan (if within two years of the Closing  Date);  provided
that, if such defect would cause the Mortgage Loan to be other than a "qualified
mortgage" as defined in Section  860G(a)(3) of the Internal  Revenue  Code,  any
such cure or  substitution  must occur  within 90 days from the date such breach
was discovered.

THE CERTIFICATES

supplement and as described in this prospectus supplement.

The pass-through rate on each class of Offered Certificates is variable and will
be  calculated  for  each   Distribution  Date  as  described  below  and  under

cap calculated  based on the weighted average mortgage rate of the Mortgage
Loans in the related loan group, less the fee rates payable to the Servicer, the
Master Servicer and the Credit Risk Manager  (collectively,  the "Administration
Costs")  and an amount,  expressed  as a per annum  rate,  equal to the net swap
payment payable to the swap provider or any swap termination  payment payable to
the swap provider  which is not payable as a result of the  occurrence of a swap
provider  trigger  event  allocable to the related loan group and in the case of
the Mezzanine Certificates,  based on each loan group, weighted in proportion to
the results of  subtracting  from the aggregate  principal  balance of each loan
group the certificate principal balance of the related Class A Certificates, and
in each case,  adjusted for the actual  number of days which have elapsed in the
related interest  accrual period.  The initial spread relating to the Class A-1A

Certificates  is 0.29% per annum.  The initial spread  relating to the Class M-3
Certificates  is 0.31% per annum.  The initial spread  relating to the Class M-4
Certificates  is 0.37% per annum.  The initial spread  relating to the Class M-5

Certificates  is 1.85% per annum.  The initial spread relating to the Class M-10
Certificates  is 2.50% per annum.  The initial spread relating to the Class M-11
Certificates  is 2.50% per annum.  Each  spread is subject to  increase  as more
fully described under  "Description of the  Certificates-Pass-Through  Rates" in
this prospectus supplement.

The  Offered  Certificates  will be  sold  by the  Depositor  to  Deutsche  Bank
Securities Inc. (the "Underwriter") on the Closing Date.

The Offered  Certificates  will be  represented  initially by one or more global
certificates registered in the name of a nominee of the Depository Trust Company
in the United  States,  or of  Clearstream  and the Euroclear  System (each,  as
defined in this  prospectus  supplement) in Europe and will be issued in minimum
dollar  denominations  of  $25,000  and  integral  multiples  of $1.00 in excess
thereof. SEE "DESCRIPTION OF THE  CERTIFICATES-BOOK-ENTRY  CERTIFICATES" IN THIS
PROSPECTUS SUPPLEMENT.

CLASS  CE  CERTIFICATES.  The  Class CE  Certificates  are not  offered  by this
prospectus   supplement.   The  Class  CE  Certificates  will  have  an  initial
certificate  principal  balance of approximately  $23,248,126,  which represents
approximately  2.10% of the aggregate principal balance of the Mortgage Loans as
of the Cut-off Date.

CLASS  P  CERTIFICATES.  The  Class  P  Certificates  are  not  offered  by this
prospectus supplement. The Class P Certificates will have an initial certificate
principal  balance of $100 and will not be entitled to  distributions in respect
of interest. The Class P Certificates will be entitled to all prepayment charges
received in respect of the Mortgage Loans.

RESIDUAL  CERTIFICATES.  The Class R Certificates (the "Residual  Certificates")
which are not offered by this  prospectus  supplement,  represent  the  residual
interests in the trust.

CREDIT ENHANCEMENT

The credit  enhancement  provided  for the benefit of the holders of the Offered
Certificates consists of excess interest,  overcollateralization,  subordination
and an interest rate swap agreement, each as described in this section and under
"Description of the Certificates-Credit  Enhancement",  "-The Interest Rate Swap
Agreement and the Swap Provider" and "-Overcollateralization Provisions" in this
prospectus supplement.

                                      S-5


- --------------------------------------------------------------------------------

EXCESS  INTEREST.  The Mortgage Loans bear interest each month in an amount that
in the aggregate is expected to exceed the amount  needed to distribute  monthly
interest on the Offered Certificates and to pay certain fees and expenses of the
trust  and the  supplemental  interest  trust  (including  any net swap  payment
payable to the swap  provider and any swap  termination  payment  payable to the
swap  provider  which is not  payable  as a result of the  occurrence  of a swap
provider trigger event).  Any excess interest from the Mortgage Loans each month
will be  available  to  absorb  realized  losses  on the  Mortgage  Loans and to
maintain or restore overcollateralization at required levels.

SUBORDINATION.  The rights of the holders of the Mezzanine  Certificates and the
Class CE  Certificates to receive  distributions  will be  subordinated,  to the
extent described in this prospectus supplement,  to the rights of the holders of
the Class A Certificates.

In   addition,   to   the   extent   described   under   "Description   of   the
Certificates--Allocation   of   Losses;   Subordination"   in  this   prospectus
supplement,

Class M-9, Class M-10, Class M-11 and Class CE Certificates will be subordinated
to the rights of the holders of the Class M-4 Certificates;

Certificates will be subordinated to the rights of the holders of the Class M-10
Certificates; and

the rights of the holders of the Class M-11 Certificates.

Subordination is intended to enhance the likelihood of regular  distributions on
the more senior  certificates in respect of interest and principal and to afford
the more senior certificates  protection against realized losses on the Mortgage
Loans,  as  described  under  "Description  of the  Certificates--Allocation  of
Losses; Subordination" in this prospectus supplement.

OVERCOLLATERALIZATION.  The aggregate principal balance of the Mortgage Loans as
of the Cut-off Date will exceed the aggregate

- --------------------------------------------------------------------------------


                                      S-6


- --------------------------------------------------------------------------------

certificate principal balance of the Class A, Mezzanine and Class P Certificates
on the Closing Date by approximately $23,248,126,  which is equal to the initial
Certificate  Principal  Balance  of  the  Class  CE  Certificates.  This  amount
represents  approximately  2.10%  of  the  aggregate  principal  balance  of the
Mortgage   Loans  as  of  the  Cut-off  Date,  and  is  the  initial  amount  of
overcollateralization  required to be provided  by the  mortgage  pool under the
pooling    and    servicing     agreement.     SEE     "DESCRIPTION    OF    THE
CERTIFICATES-OVERCOLLATERALIZATION PROVISIONS" IN THIS PROSPECTUS SUPPLEMENT.

INTEREST RATE SWAP AGREEMENT.  The Offered Certificates will have the benefit of
an Interest Rate Swap Agreement (the "Interest Rate Swap Agreement") provided by
The Royal Bank of Scotland plc (the "Swap Provider") for each  Distribution Date
commencing in June, 2006 and terminating on the Distribution Date in March 2010,
unless terminated earlier in accordance with the provisions of the Interest Rate
Swap Agreement.

Pursuant to the Interest Rate Swap Agreement, on each Distribution Date, (i) the
Securities  Administrator  (on behalf of a supplemental  interest trust and from
funds of such  trust) will be  obligated  to pay to the Swap  Provider,  a fixed
amount equal to the product of (x) 5.28%,  (y) the Swap Notional Amount for that
Distribution  Date set  forth in the  Interest  Rate  Swap  Agreement  and (z) a
fraction, the numerator of which is 30 (or, for the first Distribution Date, the
number  of days  elapsed  from  the  Closing  Date to but  excluding  the  first
Distribution  Date on a 30/360 basis),  and the denominator of which is 360 (the
"Securities  Administrator  Swap  Payment");  and (ii) the Swap Provider will be
obligated  to pay to the  supplemental  interest  trust for the  benefit  of the
holders of the Offered  Certificates (the "Swap Provider  Payment"),  a floating
amount equal to the product of (x) one-month  LIBOR (as  determined  pursuant to
the  Interest  Rate  Swap  Agreement),  (y) the Swap  Notional  Amount  for that
Distribution  Date set  forth in the  Interest  Rate  Swap  Agreement  and (z) a
fraction,  the  numerator of which is the actual number of days elapsed from the
previous  Distribution Date to but excluding the current  Distribution Date (or,
for the first  Distribution  Date,  the actual  number of days  elapsed from the
Closing Date to but excluding the first Distribution  Date), and the denominator
of which is 360.

On each Distribution Date, the net positive difference between the Swap Provider
Payment  and the  Securities  Administrator  Swap  Payment,  if any (a "Net Swap
Payment"),  will be  deposited  into a reserve  fund and will be  available  for
distribution  to  the  Offered  Certificates  in  respect  of any  interest  and
principal  shortfall  amounts and any realized  losses  allocated to the Offered
Certificates as described in this prospectus supplement. If, on any Distribution
Date, the Net Swap Payment with respect to the Offered  Certificates exceeds the
amount of the interest and principal  shortfall  amounts and any realized losses
allocated to the Offered  Certificates for such Distribution  Date, after making
the  distributions  set forth under "The  Certificates--The  Interest  Rate Swap
Agreement and the Swap Provider" in this  prospectus  supplement,  any remaining
amounts will be distributed to the Class CE  Certificates.  SEE  "DESCRIPTION OF
THE  CERTIFICATES--THE  INTEREST RATE SWAP  AGREEMENT AND THE SWAP  PROVIDER" IN
THIS PROSPECTUS SUPPLEMENT.

Upon early  termination  of the Interest  Rate Swap  Agreement,  the  Securities
Administrator (on behalf of a supplemental interest trust and from funds of such
trust) or the Swap  Provider  may be liable to make a  termination  payment (the
"Swap Termination Payment") to the other party (regardless of which party caused
the  termination).  The Swap Termination  Payment will be computed in accordance
with the procedures set forth in the Interest Rate Swap Agreement.  In the event
that the Securities Administrator is required to make a Swap Termination Payment
that  payment  will  be  paid  on  the  related  Distribution  Date,  and on any
subsequent  Distribution  Dates  until  paid in  full,  generally  prior  to any
distribution to  certificateholders.  SEE "DESCRIPTION OF THE  CERTIFICATES--THE
INTEREST  RATE  SWAP  AGREEMENT  AND  THE  SWAP  PROVIDER"  IN  THIS  PROSPECTUS
SUPPLEMENT.

- --------------------------------------------------------------------------------

Amounts payable by the Securities  Administrator in respect of Net Swap Payments
and  Swap  Termination  Payments  which  are  not  payable  as a  result  of the
occurrence of a Swap Provider trigger event will be paid to the Swap Provider on
each Distribution Date before distributions to certificateholders and will first
be  deposited to the  supplemental  interest  trust  before  payment to the Swap
Provider.

ALLOCATION OF LOSSES.  If, on any  Distribution  Date,  there is not  sufficient
excess interest, Net Swap Payments or overcollateralization  (represented by the
Class CE  Certificates)  to  absorb  realized  losses on the  Mortgage  Loans as
described   under   "Description   of  the   Certificates--Overcollateralization
Provisions" in this prospectus supplement,  then realized losses on the Mortgage
Loans will be allocated  to the Class M-11,  Class M-10,  Class M-9,  Class M-8,
Class M-7,  Class M-6,  Class M-5, Class M-4, Class M-3, Class M-2 and Class M-1
Certificates,  in that  order,  in each  case  until the  certificate  principal
balance of each such class has been reduced to zero.  The pooling and  servicing
agreement  does not permit the  allocation  of realized  losses on the  Mortgage
Loans  to  the  Class  A  Certificates;   however,  investors  in  the  Class  A
Certificates should realize that under certain loss scenarios, there will not be
enough  principal  and  interest  on the  Mortgage  Loans  to pay  the  Class  A
Certificates all interest and principal amounts to which these  certificates are
then  entitled.  SEE  "DESCRIPTION  OF THE  CERTIFICATES--ALLOCATION  OF LOSSES;
SUBORDINATION" IN THIS PROSPECTUS SUPPLEMENT.

Unless the Servicer collects  subsequent  recoveries on Mortgage Loans for which
realized  losses were  allocated to the  Mezzanine  Certificates,  once realized
losses are allocated to the Mezzanine Certificates,  their certificate principal
balances will be permanently  reduced by the amount so allocated.  However,  the
amount of any realized  losses  allocated to the Mezzanine  Certificates  may be
distributed to the holders of those certificates according to the priorities set
forth under "Description of the Certificates--Overcollateralization  Provisions"
and "Description of the  Certificates--The  Interest Rate Swap Agreement and the
Swap Provider" in this prospectus supplement.

P&I ADVANCES

The  Servicer is  required  to advance  delinquent  payments  of  principal  and
interest on the  Mortgage  Loans,  subject to the  limitations  described  under
"Description of the Certificates--P&I Advances" in this prospectus supplement. A
successor servicer will be obligated to make any required delinquency advance if
the Servicer  fails in its  obligation  to do so, to the extent  provided in the
pooling and servicing agreement.  The Servicer or any successor servicer, as the
case may be, is entitled to be  reimbursed  for these  advances,  and  therefore
these  advances  are not a form of credit  enhancement.  SEE  "SERVICING  OF THE
MORTGAGE LOANS--P&I ADVANCES" IN THIS PROSPECTUS  SUPPLEMENT AND "DESCRIPTION OF
THE SECURITIES--ADVANCES IN RESPECT OF DELINQUENCIES" IN THE PROSPECTUS.

SERVICING FEE

With respect to each Mortgage  Loan,  the amount of the servicing fee that shall
be paid to the Servicer is equal to  one-twelfth  of the product of:  (a)(i) for
the period  beginning in May 2006 and ending in February 2007,  0.30%;  (ii) for
the period  beginning in March 2007 and ending in October 2008,  0.40% and (iii)
for the period  beginning  in November  2008 and  thereafter,  0.65% and (b) the
outstanding  principal  balance of such Mortgage Loan. Such fee shall be payable
monthly,  computed  on the  basis  of  the  same  principal  amount  and  period
respecting which any related interest payment on such Mortgage Loan is computed.
The  obligation to pay the servicing fee is limited to, and the servicing fee is
payable from the interest portion of such monthly payments collected;  provided,
however,  that  accrued  and unpaid  servicing  fees  applicable  to  liquidated
mortgage  loans may be payable  out of  amounts  on  deposit  in the  collection
account as further described in the pooling and servicing agreement.

- --------------------------------------------------------------------------------

MASTER SERVICING FEE

With respect to each Mortgage  Loan,  the amount of the annual master  servicing
fee that  shall be paid to the  Master  Servicer  is,  for a period  of one full
month,  equal  to  one-twelfth  of  the  product  of (a)  0.0040%  and  (b)  the
outstanding  principal  balance of such Mortgage Loan. Such fee shall be payable
monthly,  computed  on the  basis  of  the  same  principal  amount  and  period
respecting which any related interest payment on such Mortgage Loan is computed.
The  obligation  to pay the master  servicing  fee is limited to, and the master
servicing fee is payable  from,  the interest  portion of such monthly  payments
collected. The Master Servicer will pay the trustee fee from its fee.

OPTIONAL TERMINATION

At its  option  and  subject to certain  conditions,  the  Master  Servicer  may
purchase  all of the  Mortgage  Loans in the mortgage  pool,  together  with any
properties in respect of the Mortgage Loans acquired on behalf of the trust, and
thereby effect  termination and early retirement of the certificates,  after the
aggregate  principal  balance of the Mortgage Loans (and properties  acquired in
respect of the Mortgage Loans), remaining in the trust as of the last day of the
related  due  period  has  been  reduced  to less  than or  equal  to 10% of the
aggregate  principal  balance of the Mortgage  Loans as of the Cut-off Date. SEE
"POOLING AND SERVICING AGREEMENT--TERMINATION" IN THIS PROSPECTUS SUPPLEMENT AND
"DESCRIPTION OF THE SECURITIES--TERMINATION" IN THE PROSPECTUS.

FEDERAL INCOME TAX CONSEQUENCES

Multiple  elections  will be made to  treat  designated  portions  of the  trust

purposes.    SEE   "MATERIAL    FEDERAL   INCOME   TAX    CONSIDERATIONS--REMICS
- --CHARACTERIZATION OF INVESTMENTS IN REMIC SECURITIES" IN THE PROSPECTUS.

CONSIDERATIONS FOR BENEFIT PLAN INVESTORS

It is expected  that the Offered  Certificates  may be purchased by, or with the
assets of,  employee  benefit  plans subject to the Employee  Retirement  Income
Security Act of 1974, as amended  ("ERISA") or plans or  arrangements  (each,  a
"Plan") subject to section 4975 of the Internal Revenue Code of 1986, as amended

                                  RISK FACTORS

      THE FOLLOWING INFORMATION, WHICH YOU SHOULD CONSIDER CAREFULLY, IDENTIFIES
SIGNIFICANT RISKS ASSOCIATED WITH AN INVESTMENT IN THE CERTIFICATES.

THE MORTGAGE LOANS WERE  UNDERWRITTEN  TO STANDARDS  WHICH DO NOT CONFORM TO THE
STANDARDS OF FANNIE MAE OR FREDDIE MAC.

      The  underwriting  standards of the  originator are intended to assess the
ability and  willingness  of the mortgagor to repay the debt and to evaluate the
adequacy of the property as collateral  for the mortgage  loan.  The  originator
considers,  among other things, a mortgagor's credit history,  repayment ability
and debt  service-to-income  ratio,  as well as the  value,  type and use of the
mortgaged  property.  As further  described in this prospectus  supplement,  the
underwriting  standards  of the  originator  do not  conform  to Fannie  Mae and
Freddie Mac guidelines.

      In addition,  mortgage loans  originated by the originator  generally bear
higher rates of interest than  mortgage  loans  originated  in  accordance  with
Fannie Mae and Freddie Mac guidelines and may experience  rates of  delinquency,
foreclosure  and  bankruptcy  that are  higher,  and  that may be  substantially
higher, than those experienced by mortgage loans underwritten in accordance with
Fannie Mae and Freddie Mac guidelines.

      Furthermore,  changes in the  values of  mortgaged  properties  may have a
greater effect on the delinquency,  foreclosure,  bankruptcy and loss experience
of the Mortgage  Loans than on mortgage  loans  originated  in  accordance  with
Fannie Mae and Freddie Mac guidelines. No assurance can be given that the values
of the related  mortgaged  properties have remained or will remain at the levels
in effect on the dates of origination of the related  Mortgage  Loans.  SEE "THE
MORTGAGE POOL--UNDERWRITING STANDARDS" IN THIS PROSPECTUS SUPPLEMENT.

MORTGAGE  LOANS  WITH HIGH  COMBINED  LOAN-TO-VALUE  RATIOS  LEAVE  THE  RELATED
MORTGAGOR WITH LITTLE OR NO EQUITY IN THE RELATED MORTGAGED PROPERTY.

      Approximately 31.29% of the Group IA Mortgage Loans,  approximately 29.45%
of the Group IB Mortgage Loans and approximately 43.27% of the Group II Mortgage
Loans,  in each  case,  by the  related  aggregate  principal  balance as of the
Cut-off Date,  had a combined  loan-to-value  ratio at  origination in excess of
80%.

      An overall  decline  in the  residential  real  estate  market,  a rise in
interest rates over a period of time and the condition of a mortgaged  property,
as well as other  factors,  may have the  effect  of  reducing  the value of the
mortgaged  property from the  appraised  value at the time the Mortgage Loan was
originated.  If there is a reduction in the value of the mortgaged property, the
combined  loan-to-value  ratio  may  increase  over  what it was at the time the
Mortgage  Loan was  originated.  Such an increase may reduce the  likelihood  of
liquidation or other proceeds being sufficient to satisfy the Mortgage Loan, and
any losses to the extent not  covered by the credit  enhancement  may affect the
yield to maturity of your certificates. There can be no assurance that the value
of a mortgaged  property  estimated  in any  appraisal or review is equal to the
actual value of that mortgaged property at the time of that appraisal or review.
Investors  should  note  that the  values  of the  mortgaged  properties  may be
insufficient to cover the outstanding  principal  balance of the Mortgage Loans.
There can be no assurance that the combined  loan-to-value ratio of any Mortgage
Loan determined at any time after  origination will be less than or equal to its
combined loan-to-value ratio at origination.


                                      S-12


DEVELOPMENTS  IN SPECIFIED  STATES COULD HAVE A  DISPROPORTIONATE  EFFECT ON THE
MORTGAGE LOANS DUE TO THE GEOGRAPHIC CONCENTRATION OF THE MORTGAGED PROPERTIES.

      Approximately 23.25% of the Group IA Mortgage Loans,  approximately 21.42%
of the Group IB Mortgage Loans and approximately 40.10% of the Group II Mortgage
Loans,  in each  case,  by the  related  aggregate  principal  balance as of the
Cut-off  Date,  are  secured  by  mortgaged  properties  located in the State of
California.  Approximately  0.30%  of the  aggregate  principal  balance  of the
Mortgage  Loans as of the Cut-off Date,  are located in a single  California zip
code. If the  California  residential  real estate  market should  experience an
overall  decline  in  property  values  after  the dates of  origination  of the
Mortgage  Loans,  the rates of  delinquencies,  foreclosures,  bankruptcies  and
losses on the Mortgage Loans may increase over  historical  levels of comparable
type loans, and may increase substantially.  In addition,  properties located in
California  may be more  susceptible  than homes  located in other  parts of the
country to certain types of uninsured hazards, such as earthquakes,  hurricanes,
as well as floods, mudslides and other natural disasters.

SECOND LIEN MORTGAGE LOANS RISK.

      None of the Group IA Mortgage Loans,  approximately  2.50% of the Group IB
Mortgage Loans and approximately  11.25% of the Group II Mortgage Loans, in each
case, by the related  aggregate  principal  balance as of the Cut-off Date,  are
secured by second liens on the related mortgaged  properties.  The proceeds from
any  liquidation,  insurance or  condemnation  proceedings  will be available to
satisfy the  outstanding  balance of such Mortgage Loans only to the extent that
the  claims  of the  related  senior  mortgages  have  been  satisfied  in full,
including  any related  foreclosure  costs.  In  circumstances  when it has been
determined  to be  uneconomical  to foreclose  on the  mortgaged  property,  the
servicer may write off the entire  balance of such  Mortgage Loan as a bad debt.
The foregoing  considerations will be particularly  applicable to Mortgage Loans
secured by second liens that have high combined  loan-to-value ratios because it
is comparatively more likely that the servicer would determine foreclosure to be
uneconomical in the case of such Mortgage  Loans.  The rate of default of second
lien Mortgage  Loans may be greater than that of mortgage loans secured by first
liens on comparable properties.

BALLOON MORTGAGE LOAN RISK.

      Mortgage  Loans that are balloon loans pose a risk because a borrower must
make a large lump sum payment of principal  at the end of the loan term.  If the
borrower is unable to pay the lump sum or refinance  such  amount,  the servicer
will not be obligated to advance the principal portion of that lump sum payment,
you may  suffer a loss.  Approximately  21.48% of the Group IA  Mortgage  Loans,
approximately  26.87% of the Group IB Mortgage Loans and approximately 27.38% of
the Group II  Mortgage  Loans,  in each  case,  by related  aggregate  principal
balance as of the Cut-off Date, are balloon loans.

INTEREST ONLY MORTGAGE LOAN RISK.

      Approximately  17.52% of the Group IA Mortgage Loans,  approximately 7.87%
of the Group IB Mortgage Loans and approximately 22.37% of the Group II Mortgage
Loans,  in each  case,  by the  related  aggregate  principal  balance as of the
Cut-off  Date,  require the  borrowers to make monthly  payments only of accrued
interest   for  the  first  five  years   following   origination.   After  such
interest-only  period,  the borrower's  monthly  payment will be recalculated to
cover both interest and principal so that the Mortgage Loan will amortize  fully
prior to its final payment date. If the monthly payment  increases,  the related
borrower  may not be able to pay the  increased  amount  and may  default or may
refinance  the related  Mortgage  Loan to avoid the higher  payment.  Because no
principal payments may be made or advanced on such Mortgage Loans for five years
following  origination,  the  certificateholders  will receive smaller principal
distributions during such


                                      S-13


period than they would have received if the related  borrowers  were required to
make  monthly  payments of interest and  principal  for the entire lives of such
Mortgage  Loans.  This slower  rate of  principal  distributions  may reduce the
return on an  investment  in the Offered  Certificates  that are  purchased at a
discount.

THE  MEZZANINE  CERTIFICATES  WILL BE MORE  SENSITIVE  TO LOSSES ON THE MORTGAGE
LOANS THAN THE CLASS A CERTIFICATES  BECAUSE THEY ARE SUBORDINATE TO THE CLASS A
CERTIFICATES.

      The  weighted  average  lives of, and the yields to maturity on, the Class
M-1,  Class M-2,  Class M-3,  Class M-4,  Class M-5, Class M-6, Class M-7, Class
M-8, Class M-9,  Class M-10 and Class M-11  Certificates  will be  progressively
more sensitive,  in that order, to the rate and timing of mortgagor defaults and
the  severity of ensuing  losses on the Mortgage  Loans.  If the actual rate and
severity  of losses on the  Mortgage  Loans is higher  than those  assumed by an
investor  in  these  certificates,   the  actual  yield  to  maturity  of  these
certificates  may be lower than the yield  anticipated  by the investor based on
such assumption.  The timing of losses on the Mortgage Loans will also affect an
investor's  actual yield to maturity,  even if the rate of defaults and severity
of losses over the life of the mortgage pool are  consistent  with an investor's
expectations.  In general,  the earlier a loss occurs, the greater the effect on
an investor's  yield to maturity.  Realized losses on the Mortgage Loans, to the
extent they exceed the amount of excess interest,  overcollateralization and net
swap  payments  received  from the swap provider in respect of the interest rate
swap agreement,  will reduce the certificate principal balances of the Mezzanine
Certificates beginning with the class of Mezzanine Certificates then outstanding
with the lowest payment priority. As a result of such reductions,  less interest
will accrue on each such class of Mezzanine Certificates than would otherwise be
the case. However,  the amount of any realized losses allocated to the Mezzanine
Certificates may be distributed to the holders of those  certificates  according
to    the     priorities    set    forth    under     "Description     of    the
Certificates--Overcollateralization   Provisions"   and   "Description   of  the
Certificates--The  Interest Rate Swap  Agreement and the Swap  Provider" in this
prospectus supplement.

THE MEZZANINE  CERTIFICATES  GENERALLY WILL NOT BE ENTITLED TO RECEIVE PRINCIPAL
PAYMENTS  UNTIL JUNE 2009 WHICH MAY RESULT IN A GREATER RISK OF LOSS RELATING TO
THESE CERTIFICATES.

      Unless  the  aggregate  certificate  principal  balance  of  the  Class  A
Certificates  has been reduced to zero, the Mezzanine  Certificates  will not be
entitled to any principal distributions until at least June 2009 or a later date
as  provided  in this  prospectus  supplement  or  during  any  period  in which
delinquencies   on  the  Mortgage  Loans  exceed  the  levels  set  forth  under
"Description  of  the  Certificates--Principal   Distributions  on  the  Offered
Certificates" in this prospectus  supplement.  As a result, the weighted average
lives of the  Mezzanine  Certificates  will be longer  than would be the case if
distributions  of principal were allocated among all of the  certificates at the
same time.  As a result of the longer  weighted  average  lives of the Mezzanine
Certificates, the holders of these certificates have a greater risk of suffering
a loss on their  investments.  Further,  because  such  certificates  might  not
receive any principal if the delinquency  levels set forth under "Description of
the  Certificates--Principal  Distributions on the Offered Certificates" in this
prospectus  supplement  are exceeded,  it is possible for such  certificates  to
receive no principal  distributions on a particular Distribution Date even if no
losses have occurred on the mortgage pool.

THE  OFFERED  CERTIFICATES  WILL BE LIMITED  OBLIGATIONS  SOLELY OF THE  ISSUING
ENTITY AND NOT OF ANY OTHER PARTY.

      The Offered  Certificates  will not represent an interest in or obligation
of  the  depositor,   the  servicer,   the  master   servicer,   the  securities
administrator,   the  originator,   the  trustee  or  any  of  their  respective
affiliates.  Neither the Offered  Certificates nor the underlying Mortgage Loans
will be guaranteed or insured by any governmental agency or instrumentality,  or
by the depositor, the


                                      S-14


servicer, the master servicer, the securities administrator, the originator, the
trustee or any of their respective  affiliates.  Proceeds of the assets included
in the trust will be the sole source of  payments  on the Offered  Certificates,
and there will be no recourse to the depositor,  the servicer,  the  originator,
the master  servicer,  the  securities  administrator,  the trustee or any other
entity  in  the  event  that  these  proceeds  are   insufficient  or  otherwise
unavailable to make all payments provided for under the Offered Certificates.

THE DIFFERENCE  BETWEEN THE  PASS-THROUGH  RATES ON THE CLASS A CERTIFICATES AND
MEZZANINE  CERTIFICATES  AND THE MORTGAGE RATES ON THE MORTGAGE LOANS MAY RESULT
IN INTEREST SHORTFALLS ON SUCH CERTIFICATES.

      The  yield to  maturity  on the  Class A  Certificates  and the  Mezzanine
Certificates  may be  affected by the  resetting  of the  mortgage  rates on the
adjustable-rate  Mortgage  Loans  included in the mortgage pool on their related
adjustment  dates.  In  addition,  because the mortgage  rate for  approximately
83.99% of the Mortgage Loans, by aggregate  principal  balance as of the Cut-off
Date, adjusts based on Six-Month LIBOR plus a fixed percentage amount, such rate
could be higher than prevailing market interest rates, and this may result in an
increase  in the  rate  of  prepayments  on  such  Mortgage  Loans  after  their
adjustments.  Finally, the mortgage rates on such adjustable-rate Mortgage Loans
are  based on  Six-Month  LIBOR  while  the  pass-through  rates on the  Class A
Certificates  and the  Mezzanine  Certificates  are  based on  one-month  LIBOR.
Consequently,  the  application to such  certificates  of the rate cap, which is
generally  equal to the weighted  average coupon on the Mortgage  Loans,  net of
certain fees of the trust and the supplemental interest trust (including any net
swap  payment  payable to the Swap  Provider  and any swap  termination  payment
payable to the Swap Provider  which is not payable as a result of the occurrence
of a Swap Provider trigger event),  could adversely affect the yield to maturity
on such certificates.  In addition, the rate cap will decrease if Mortgage Loans
with  relatively high mortgage rates prepay at a faster rate than Mortgage Loans
with relatively low mortgage rates.

      If the  pass-through  rates on the Class A  Certificates  or the Mezzanine
Certificates  are limited for any  Distribution  Date,  the  resulting  interest
shortfalls  may be  recovered by the holders of these  certificates  on the same
Distribution Date or on future Distribution Dates on a subordinated basis to the
extent that on such  Distribution  Date or future  Distribution  Dates there are
available  funds  remaining  after  certain other  distributions  on the Offered
Certificates  and the payment of certain  fees and expenses of the trust and the
supplemental  interest trust (including any net swap payment payable to the Swap
Provider and any swap termination  payment payable to the Swap Provider which is
not payable as a result of the occurrence of a Swap Provider trigger event). The
ratings on the  Offered  Certificates  will not address  the  likelihood  of any
recovery of interest  shortfalls  by holders of the  Offered  Certificates  from
amounts collected on the Mortgage Loans. SEE "YIELD ON THE CERTIFICATES--SPECIAL
YIELD CONSIDERATIONS" IN THIS PROSPECTUS SUPPLEMENT.

      Amounts used to pay such interest  shortfalls on the Offered  Certificates
may be  supplemented  by the Interest Rate Swap Agreement to the extent that the
floating  payment  required  to be made by the Swap  Provider  exceeds the fixed
payment  required to be made by the Securities  Administrator  (on behalf of the
supplemental  interest  trust)  on any  Distribution  Date  and such  amount  is
available in the priority described in this prospectus supplement.  However, the
amount  received from the Swap Provider  under the Interest Rate Swap  Agreement
may be  insufficient  to pay the  holders of the Offered  Certificates  the full
amount of interest which they would have received  absent the limitations of the
rate cap.


                                      S-15


THE RATE AND TIMING OF PRINCIPAL  DISTRIBUTIONS  ON THE CLASS A CERTIFICATES AND
THE  MEZZANINE  CERTIFICATES  WILL BE AFFECTED BY  PREPAYMENT  SPEEDS AND BY THE
PRIORITY OF PAYMENT ON SUCH CERTIFICATES.

      The rate and timing of distributions allocable to principal on the Class A
Certificates and the Mezzanine Certificates will depend, in general, on the rate
and timing of principal  payments  (including  prepayments and collections  upon
defaults, liquidations and repurchases) on the Mortgage Loans and the allocation
thereof to pay principal on such  certificates  as described in  "Description of
the  Certificates--Principal  Distributions on the Offered Certificates" in this
prospectus  supplement.  As  is  the  case  with  mortgage  backed  pass-through
certificates  generally,  the Offered  Certificates  are subject to  substantial
inherent  cash-flow  uncertainties  because the Mortgage Loans may be prepaid at
any time. However,  with respect to approximately  76.19% of the Mortgage Loans,
by aggregate  principal  balance of the Mortgage Loans as of the Cut-off Date, a
prepayment  may  subject  the  related  mortgagor  to  a  prepayment  charge.  A
prepayment charge may or may not act as a deterrent to prepayment of the related
Mortgage Loan. SEE "THE MORTGAGE POOL" IN THIS PROSPECTUS SUPPLEMENT.

      Generally, when prevailing interest rates are increasing, prepayment rates
on mortgage loans tend to decrease;  a decrease in the  prepayment  rates on the
Mortgage Loans will result in a reduced rate of return of principal to investors
in the  Class A  Certificates  and the  Mezzanine  Certificates  at a time  when
reinvestment  at such higher  prevailing  rates would be desirable.  Conversely,
when prevailing interest rates are declining, prepayment rates on mortgage loans
tend to increase; an increase in the prepayment rates on the Mortgage Loans will
result in a greater  rate of return of  principal  to  investors  in the Class A
Certificates  and  Mezzanine   Certificates  at  a  time  when  reinvestment  at
comparable yields may not be possible.

      Distributions  of principal  will be made to the holders of the  Mezzanine
Certificates   according  to  the  priorities   described  in  this   prospectus
supplement.  The  timing of  commencement  of  principal  distributions  and the
weighted average life of each such class of certificates will be affected by the
rates of prepayment on the Mortgage Loans  experienced both before and after the
commencement of principal distributions on such classes. For further information
regarding the effect of principal  prepayments on the weighted  average lives of
the Offered  Certificates,  SEE "YIELD ON THE  CERTIFICATES"  IN THIS PROSPECTUS
SUPPLEMENT,  INCLUDING  THE TABLES  ENTITLED  "PERCENT  OF  INITIAL  CERTIFICATE
PRINCIPAL  BALANCE  OUTSTANDING  AT THE SPECIFIED  PERCENTAGES OF THE PREPAYMENT
ASSUMPTION."

THE YIELD TO MATURITY ON THE  OFFERED  CERTIFICATES  WILL DEPEND ON A VARIETY OF
FACTORS.

      The yield to maturity on the Offered Certificates will depend on:

      o     the applicable pass-through rate thereon;

      o     the applicable purchase price;

      o     the rate and timing of principal payments (including prepayments and
            collections  upon defaults,  liquidations  and  repurchases) and the
            allocation  thereof to reduce the certificate  principal  balance of
            the Offered Certificates;

      o     the rate,  timing and  severity of realized  losses on the  Mortgage
            Loans,  adjustments  to the  mortgage  rates on the  adjustable-rate
            Mortgage  Loans  included in the mortgage pool, the amount of excess
            interest  generated by the Mortgage  Loans and the allocation to the
            Offered Certificates of certain interest shortfalls; and


                                      S-16


      o     payments  due from the  supplemental  interest  trust in  respect of
            payments  received  from the Swap  Provider  under the Interest Rate
            Swap Agreement.

      In general,  if the Offered  Certificates  are  purchased at a premium and
principal  distributions  thereon occur at a rate faster than anticipated at the
time of purchase,  the  investor's  actual yield to maturity  will be lower than
that assumed at the time of purchase.  Conversely,  if the Offered  Certificates
are purchased at a discount and principal  distributions thereon occur at a rate
slower than that  anticipated  at the time of purchase,  the  investor's  actual
yield to maturity will be lower than that originally assumed.

      The proceeds to the  Depositor  from the sale of the Offered  Certificates
were  determined  based on a  number  of  assumptions,  including  a  prepayment
assumption  of 100% PPC (based on the assumed  prepayment  rates set forth under
"Yield  on  the   Certificates--Weighted   Average  Lives"  in  this  prospectus
supplement) with respect to the adjustable-rate  Mortgage Loans and a prepayment
assumption  of 100% PPC (based on the assumed  prepayment  rates set forth under
"Yield  on  the   Certificates--Weighted   Average  Lives"  in  this  prospectus
supplement) with respect to the fixed-rate  Mortgage Loans, and weighted average
lives  corresponding  thereto. No representation is made that the Mortgage Loans
will prepay at such rate or at any other  rate.  The yield  assumptions  for the
Offered Certificates will vary as determined at the time of sale.

THE  YIELD  TO  MATURITY  ON THE  MEZZANINE  CERTIFICATES  WILL BE  PARTICULARLY
SENSITIVE TO THE RATE OF PREPAYMENTS ON THE MORTGAGE LOANS.

      The multiple  class  structure of the  Mezzanine  Certificates  causes the
yield of these classes to be  particularly  sensitive to changes in the rates of
prepayment of the Mortgage  Loans.  Because  distributions  of principal will be
made to the holders of such certificates  according to the priorities  described
in this  prospectus  supplement,  the  yield  to  maturity  on such  classes  of
certificates  will be sensitive to the rates of prepayment on the Mortgage Loans
experienced both before and after the commencement of principal distributions on
such classes. The yield to maturity on such classes of certificates will also be
extremely  sensitive  to losses due to defaults on the  Mortgage  Loans (and the
timing  thereof),  to the extent these losses are not covered by excess cashflow
otherwise payable to the Class CE Certificates, net swap payments received under
the  Interest  Rate  Swap  Agreement  or  allocated  to  a  class  of  Mezzanine
Certificates  with a lower payment priority.  Furthermore,  as described in this
prospectus  supplement,  the timing of receipt of principal  and interest by the
Mezzanine Certificates may be adversely affected by losses even if these classes
of certificates do not ultimately bear such loss.

VIOLATION OF CONSUMER PROTECTION LAWS MAY RESULT IN LOSSES ON THE MORTGAGE LOANS
AND YOUR CERTIFICATES.

      Applicable state laws generally regulate interest rates and other charges,
require  certain  disclosure,  and  require  licensing  of the  originators.  In
addition,  other state laws,  public  policy and  general  principles  of equity
relating to the protection of consumers, unfair and deceptive practices and debt
collection  practices may apply to the origination,  servicing and collection of
the Mortgage Loans.

      The Mortgage Loans are also subject to federal laws, including:

      o     the  Federal  Truth-in-Lending  Act  and  Regulation  Z  promulgated
            thereunder,  which require  certain  disclosures  to the  mortgagors
            regarding the terms of the Mortgage Loans;


                                      S-17


      o     the  Equal  Credit  Opportunity  Act and  Regulation  B  promulgated
            thereunder, which prohibit discrimination on the basis of age, race,
            color, sex, religion,  marital status,  national origin,  receipt of
            public  assistance  or the  exercise of any right under the Consumer
            Credit Protection Act, in the extension of credit;

      o     the Fair Credit Reporting Act, which regulates the use and reporting
            of information related to the mortgagor's credit experience; and

      o     the Depository Institutions Deregulation and Monetary Control Act of
            1980, which preempts certain state usury laws.

      Violations of certain provisions of these federal and state laws may limit
the  ability of the  servicer  to  collect  all or part of the  principal  of or
interest on the related  Mortgage  Loans and in addition could subject the trust
to damages and  administrative  enforcement.  In particular,  the failure of the
originators to comply with certain requirements of the Federal  Truth-in-Lending
Act,  as  implemented  by  Regulation  Z, could  subject  the trust to  monetary
penalties,  and result in the mortgagors'  rescinding the Mortgage Loans against
the trust.  In addition to federal law, some states have enacted,  or may enact,
laws or regulations that prohibit inclusion of some provisions in Mortgage Loans
that have interest  rates or origination  costs in excess of prescribed  levels,
and  require  that  mortgagors  be  given  certain   disclosures  prior  to  the
consummation  of the  Mortgage  Loans and  restrict  the  servicer's  ability to
foreclose in response to mortgagor  defaults.  The failure of the originators to
comply  with  these  laws  could  subject  the  trust  to  significant  monetary
penalties,  could result in the mortgagors rescinding the Mortgage Loans against
the trust and/or  limit the  servicer's  ability to  foreclose  upon the related
mortgaged properties in the event of mortgagor defaults.

      Under the  anti-predatory  lending laws of some states,  the  mortgagor is
required to meet a net tangible benefits test in connection with the origination
of the related  mortgage  loan.  This test may be highly  subjective and open to
interpretation. As a result, a court may determine that a mortgage loan does not
meet the  test  even if the  originator  reasonably  believed  that the test was
satisfied.  Any  determination  by a court that a Mortgage  Loan included in the
trust  fund  does not meet the test  will  result  in a  violation  of the state
anti-predatory  lending  law,  in which case the  Sponsor  will be  required  to
purchase that Mortgage Loan from the trust fund.

      The Sponsor will  represent  that, as of the Closing  Date,  each Mortgage
Loan is in compliance with applicable federal and state laws and regulations. In
the event of a breach of such  representation,  the Sponsor will be obligated to
cure such breach or  repurchase  or replace the  affected  Mortgage  Loan in the
manner described in the prospectus.  If the Sponsor is unable or otherwise fails
to  satisfy  such  obligations,  the yield on the  Offered  Certificates  may be
materially and adversely affected.

YOUR  DISTRIBUTIONS  COULD BE ADVERSELY AFFECTED BY THE BANKRUPTCY OR INSOLVENCY
OF CERTAIN PARTIES.

      The Sponsor will treat the transfer of the Mortgage Loans to the Depositor
as a sale of the Mortgage Loans.  However, if the Sponsor becomes bankrupt,  the
trustee in bankruptcy  may argue that the Mortgage  Loans were not sold but were
only  pledged to secure a loan to the  Sponsor.  If that  argument is made,  you
could experience delays or reductions in payments on the  certificates.  If that
argument is successful,  the bankruptcy trustee could elect to sell the Mortgage
Loans and pay down the  certificates  early.  Thus,  you could lose the right to
future  payments of  interest,  and might  suffer  reinvestment  loss in a lower
interest rate environment.


                                      S-18


      In addition, if the Master Servicer becomes bankrupt, a bankruptcy trustee
or receiver may have the power to prevent the appointment of a successor  master
servicer.   Any  related   delays  in   servicing   could  result  in  increased
delinquencies or losses on the Mortgage Loans.

INTEREST  GENERATED BY THE  MORTGAGE  LOANS MAY BE  INSUFFICIENT  TO MAINTAIN OR
RESTORE OVERCOLLATERALIZATION.

      The Mortgage  Loans are expected to generate  more interest than is needed
to pay  interest  owed on the Offered  Certificates  and to pay certain fees and
expenses of the trust and the  supplemental  interest  trust  (including any net
swap  payment  payable to the Swap  Provider  and any swap  termination  payment
payable to the Swap Provider  which is not payable as a result of the occurrence
of a Swap  Provider  trigger  event).  Any remaining  interest  generated by the
Mortgage  Loans will then be used to absorb  losses  that occur on the  Mortgage
Loans.  After these  financial  obligations of the trust are covered,  available
excess  interest  generated  by the  Mortgage  Loans will be used to maintain or
restore the  overcollateralization.  We cannot assure you, however,  that enough
excess  interest will be generated to maintain or restore the required  level of
overcollateralization.  The  factors  described  below will affect the amount of
excess interest that the Mortgage Loans will generate:

      o     Every time a Mortgage Loan is prepaid in full,  excess  interest may
            be reduced  because such Mortgage Loan will no longer be outstanding
            and  generating  interest  or, in the case of a partial  prepayment,
            will be generating less interest.

      o     Every time a Mortgage  Loan is  liquidated  or written  off,  excess
            interest may be reduced because such Mortgage Loan will no longer be
            outstanding and generating interest.

      o     If the rates of  delinquencies,  defaults or losses on the  Mortgage
            Loans are higher than expected,  excess  interest will be reduced by
            the  amount  necessary  to  compensate  for any  shortfalls  in cash
            available   to   make   required   distributions   on  the   Offered
            Certificates.

      o     The  adjustable-rate  Mortgage Loans have mortgage rates that adjust
            less frequently than, and on the basis of an index that is different
            from,  the index used to  determine  the  pass-through  rates on the
            Offered  Certificates,   and  the  fixed-rate  Mortgage  Loans  have
            mortgage  rates that do not adjust.  As a result,  the  pass-through
            rates on the Offered  Certificates may increase relative to mortgage
            rates on the Mortgage Loans, requiring that a greater portion of the
            interest  generated  by the  Mortgage  Loans  be  applied  to  cover
            interest on such certificates.

INTEREST  PAYMENTS ON THE MORTGAGE LOANS MAY BE  INSUFFICIENT TO PAY INTEREST ON
YOUR CERTIFICATES.

      When a Mortgage Loan is prepaid in full, the mortgagor is charged interest
only up to the date on which  payment is made,  rather than for an entire month.
This may result in a shortfall in interest collections  available for payment on
the next  Distribution  Date. The servicer is required to cover a portion of the
shortfall in interest collections that are attributable to voluntary prepayments
in full on the Mortgage Loans during the related  Prepayment Period, but only up
the  servicing  fee payable to the  servicer  for the related  interest  accrual
period.  In  addition,  if the  servicer  fails to pay all or a portion of these
amounts,  the  master  servicer  is  required  to  pay  such  amounts  up to the
compensation  payable to the master  servicer for the related  interest  accrual
period.  If the credit  enhancement is  insufficient  to cover this shortfall in
excess of the amount the servicer or the master servicer covers, you may incur a
loss. In addition, the servicer will not be required to cover


                                      S-19


shortfalls  in  interest  collections  due  to  bankruptcy  proceedings  or  the
application of the Servicemembers Civil Relief Act (the "Relief Act") or similar
state or local laws.

      On any Distribution Date, any shortfalls resulting from the application of
the  Relief  Act or  similar  state or local  laws and any  prepayment  interest
shortfalls  to the  extent  not  covered by  compensating  interest  paid by the
servicer  or the  master  servicer  will be  allocated,  FIRST,  to the Class CE
Certificates,  SECOND, to the Class M-11 Certificates,  THIRD, to the Class M-10
Certificates,  FOURTH,  to the Class M-9  Certificates,  FIFTH, to the Class M-8
Certificates,  SIXTH, to the Class M-7 Certificates,  SEVENTH,  to the Class M-6
Certificates,  EIGHTH,  to the Class M-5  Certificates,  NINTH, to the Class M-4
Certificates,  TENTH, to the Class M-3 Certificates,  ELEVENTH, to the Class M-2
Certificates,  TWELFTH,  to the Class M-1  Certificates  and THIRTEENTH,  to the
Class A  Certificates,  on a PRO RATA basis,  based on their  respective  senior
interest  distribution amounts for such Distribution Date before such reduction.
The holders of the Offered  Certificates  will be entitled to reimbursement  for
any such  interest  shortfalls  but only to the  extent of  available  funds and
amounts payable by the Swap Provider under the Interest Rate Swap Agreement, and
in   the   order   of   priority   set   forth   under   "Description   of   the
Certificates--Overcollateralization  Provisions"  and --"The  Interest Rate Swap
Agreement  and the  Swap  Provider"  in this  prospectus  supplement.  If  these
shortfalls are allocated to the Offered Certificates the amount of interest paid
to those  certificates  will be reduced,  adversely  affecting the yield on your
investment.

THE LIQUIDITY OF YOUR CERTIFICATES MAY BE LIMITED.

      The  Underwriter  has no  obligation  to make a  secondary  market  in the
classes  of  Offered  Certificates.  There  is  therefore  no  assurance  that a
secondary  market  will  develop  or,  if it  develops,  that it will  continue.
Consequently, you may not be able to sell your certificates readily or at prices
that will enable you to realize your  desired  yield.  The market  values of the
certificates are likely to fluctuate;  these fluctuations may be significant and
could result in significant losses to you.

      The secondary markets for asset-backed securities have experienced periods
of illiquidity and can be expected to do so in the future.  Illiquidity can have
a  severely  adverse  effect on the  prices of  securities  that are  especially
sensitive  to  prepayment,  credit  or  interest  rate  risk,  or that have been
structured  to  meet  the  investment  requirements  of  limited  categories  of
investors.

THE INTEREST RATE SWAP AGREEMENT AND THE SWAP PROVIDER.

      Any amounts  received from the Swap Provider  under the Interest Rate Swap
Agreement  will be applied as described  in this  prospectus  supplement  to pay
interest  shortfalls,   maintain  or  restore  overcollateralization  and  cover
realized  losses on the Mortgage  Loans  allocated to the Offered  Certificates.
However,  no amounts  will be payable by the Swap  Provider  unless the floating
amount owed by the Swap Provider on a Distribution Date exceeds the fixed amount
owed to the Swap Provider on such  Distribution  Date.  This will  generally not
occur  except in periods when  one-month  LIBOR (as  determined  pursuant to the
Interest Rate Swap  Agreement)  exceeds 5.28%. No assurance can be made that any
amounts will be received  under the Interest  Rate Swap  Agreement,  or that any
such  amounts that are received  will be  sufficient  to maintain or restore the
required  level of  overcollateralization  or to cover  interest  shortfalls and
realized  losses on the  Mortgage  Loans  which  are  allocated  to the  Offered
Certificates.  Any net swap payment payable to the Swap Provider under the terms
of  the  Interest  Rate  Swap  Agreement  will  reduce  amounts   available  for
distribution to certificateholders, and may reduce the pass-through rates of the
certificates.  If the rate of  prepayments  on the Mortgage Loans is faster than
anticipated,  the schedule on which  payments  due under the Interest  Rate Swap
Agreement  are  calculated  may exceed the  aggregate  principal  balance of the
Mortgage  Loans,   thereby  increasing  the  relative   proportion  of  interest
collections  on the Mortgage  Loans that must be applied to make net payments to
the  Swap  Provider.  The  combination  of a rapid  rate of  prepayment  and low
prevailing  interest  rates  could  adversely  affect the yields on the  Offered
Certificates. In addition,


                                      S-20


any swap termination  payment payable to the Swap Provider in the event of early
termination  of the  Interest  Rate Swap  Agreement  which was not caused by the
occurrence of a Swap Provider  trigger event will reduce  amounts  available for
distribution to certificateholders.

      Upon early termination of the Interest Rate Swap Agreement, the securities
administrator  (on  behalf  of the  supplemental  interest  trust)  or the  Swap
Provider  may be liable to make a Swap  Termination  Payment to the other  party
(regardless of which party caused the termination). The Swap Termination Payment
will be computed in  accordance  with the  procedures  set forth in the Interest
Rate Swap Agreement.  In the event that the securities  administrator (on behalf
of the  supplemental  interest  trust) is  required  to make a Swap  Termination
Payment,  that payment will be paid on the related Distribution Date, and on any
subsequent   Distribution   Dates  until  paid  in  full,   generally  prior  to
distributions  to  certificateholders.  This feature may result in losses on the
certificates.   Due  to  the  priority  of  the  application  of  the  Available
Distribution  Amount,  the Mezzanine  Certificates  will bear the effects of any
shortfalls  resulting from a Net Swap Payment or Swap Termination Payment by the
securities   administrator  before  such  effects  are  borne  by  the  Class  A
Certificates  and therefore,  one or more classes of Mezzanine  Certificates may
suffer a loss as a result of such payment.

      To the extent that  distributions  on the Offered  Certificates  depend in
part on payments to be received by the  securities  administrator  (on behalf of
the  supplemental  interest trust) under the Interest Rate Swap  Agreement,  the
ability  of the  securities  administrator  to make  such  distributions  on the
Offered  Certificates  will be subject to the credit risk of the Swap  Provider.
Although there is a mechanism in place to facilitate replacement of the Interest
Rate Swap Agreement upon the default or credit  impairment of the Swap Provider,
there can be no assurance  that any such mechanism will result in the ability of
the trustee to obtain a suitable replacement  interest rate swap agreement.  The
credit  ratings of the Swap Provider on the date of this  prospectus  supplement
are  lower  than  the  ratings  assigned  to  the  Class  A  Certificates.   See
"Description of the Certificates--The  Interest Rate Swap Agreement and the Swap
Provider" in this prospectus supplement.

THE  RETURN ON YOUR  CERTIFICATES  COULD BE  REDUCED  BY  SHORTFALLS  DUE TO THE
APPLICATION OF THE RELIEF ACT.

      The  Relief  Act and  similar  state  or  local  laws  provide  relief  to
mortgagors who enter active military service and to mortgagors in reserve status
who are  called to  active  military  service  after  the  origination  of their
mortgage loans. The ongoing military operations of the United States in Iraq and
Afghanistan have caused an increase in the number of citizens in active military
duty,  including those citizens  previously in reserve status.  Under the Relief
Act the  interest  rate  applicable  to a  mortgage  loan for which the  related
mortgagor  is  called  to  active  military  service  will be  reduced  from the
percentage  stated in the related  mortgage  note to 6.00%.  This  interest rate
reduction  and any  reduction  provided  under similar state or local laws could
result in an interest  shortfall  because the master  servicer  and the servicer
will not be able to collect  the amount of  interest  which  otherwise  would be
payable with respect to such Mortgage Loan if the Relief Act or similar state or
local law was not  applicable  thereto.  This  shortfall will not be paid by the
mortgagor on future due dates or advanced by the master servicer or the servicer
and,  therefore,  will  reduce  the  amount  available  to pay  interest  to the
certificateholders  on subsequent  Distribution  Dates.  We do not know how many
Mortgage  Loans  in the  mortgage  pool  have  been  or may be  affected  by the
application of the Relief Act or similar state or local law.

POSSIBLE REDUCTION OR WITHDRAWAL OF RATINGS ON THE OFFERED CERTIFICATES.

      Each rating agency rating the Offered  Certificates may change or withdraw
its initial ratings at any time in the future if, in its judgment, circumstances
warrant a change.  No person is  obligated  to  maintain  the  ratings  at their
initial levels. If a rating agency reduces or withdraws its


                                      S-21


rating on one or more classes of the Offered  Certificates,  the  liquidity  and
market value of the affected certificates is likely to be reduced.

SUITABILITY OF THE OFFERED CERTIFICATES AS INVESTMENTS.

      The Offered  Certificates  are not suitable  investments  for any investor
that requires a regular or predictable  schedule of monthly  payments or payment
on any specific  date. The Offered  Certificates  are complex  investments  that
should  be  considered  only by  investors  who,  either  alone  or  with  their
financial, tax and legal advisors, have the expertise to analyze the prepayment,
reinvestment, default and market risk, the tax consequences of an investment and
the interaction of these factors.

FICO SCORES ARE NOT AN INDICATOR OF FUTURE PERFORMANCE OF MORTGAGORS.

      Investors  are  encouraged  to be aware that FICO scores are based on past
payment  history of the mortgagor.  Investors are encouraged not to rely on FICO
scores  as an  indicator  of  future  borrower  performance.  See "The  Mortgage
Pool--Underwriting Standards" in this prospectus supplement.

      ALL  CAPITALIZED  TERMS USED IN THIS  PROSPECTUS  SUPPLEMENT WILL HAVE THE
MEANINGS ASSIGNED TO THEM UNDER "DESCRIPTION OF THE  CERTIFICATES--GLOSSARY"  OR
IN THE PROSPECTUS UNDER "INDEX OF DEFINED TERMS."

                                 USE OF PROCEEDS

      DB Structured Products, Inc. (the "Sponsor"), will sell the Mortgage Loans
to ACE  Securities  Corp.  (the  "Depositor")  and the Depositor will convey the
Mortgage  Loans to the trust  fund in  exchange  for and  concurrently  with the
delivery  of the  certificates.  Net  proceeds  from  the  sale  of the  Offered
Certificates  will be applied by the  Depositor  to the purchase of the Mortgage
Loans from the Sponsor.  Such net  proceeds  together  with  certain  classes of
certificates  not  offered by this  prospectus  supplement  will  represent  the
purchase  price to be paid by the  Depositor  to the  Sponsor  for the  Mortgage
Loans. The Mortgage Loans were previously purchased by the Sponsor directly from
Option One Mortgage Corporation (the "Originator").

                                THE MORTGAGE POOL

GENERAL

The  pool of  mortgage  loans  (the  "Mortgage  Pool")  will  consist  of  5,501
conventional,  one- to  four-family,  first  and  second  lien,  fixed-rate  and
adjustable-rate  mortgage  loans  (the  "Mortgage  Loans") on  residential  real
properties (the "Mortgaged Properties") having an aggregate principal balance as
of the  Cut-off  Date  of  approximately  $1,107,055,226  after  application  of
scheduled  payments due on or before the Cut-off  Date whether or not  received,
and subject to a permitted variance of plus or minus 5%. The Mortgage Loans have
original  terms to  maturity  of not  greater  than 30 years.  For  purposes  of
calculating  interest and principal  distributions  on the Class A Certificates,
the Mortgage  Loans have been divided into three loan groups,  designated as the
"Group IA  Mortgage  Loans",  the  "Group IB  Mortgage  Loans" and the "Group II
Mortgage  Loans." The Group IA Mortgage  Loans consist of 2,241  fixed-rate  and
adjustable-rate  mortgage loans having an aggregate  principal balance as of the
Cut-off  Date of  approximately  $449,214,623  after  application  of  scheduled
payments due on or before the Cut-off Date whether or not received,  and subject
to a permitted variance of plus or minus 5%. The principal balances of the Group
IA Mortgage Loans at origination conformed to Freddie Mac loan limits. The Group
IB Mortgage Loans consist of 1,260 fixed-rate and adjustable-rate mortgage loans
having an aggregate principal


                                      S-22


balance as of the Cut-off Date of approximately  $227,195,759  after application
of scheduled payments due on or before the Cut-off Date whether or not received.
The principal  balances of the Group IB Mortgage Loans at origination  conformed
to Fannie Mae loan limits.  The Group II Mortgage Loans consist of approximately
2,000  fixed-rate  and  adjustable-rate   mortgage  loans  having  an  aggregate
principal  balance as of the Cut-off Date of  approximately  $430,644,844  after
application  of scheduled  payments due on or before the Cut-off Date whether or
not  received,  and  subject to a  permitted  variance  of plus or minus 5%. The
principal  balances of the Group II Mortgage Loans at origination may or may not
have conformed to Freddie Mac or Fannie Mae loan limits.

      Approximately 57.69% of the Mortgage Loans, by aggregate principal balance
as of the  Cut-off  Date,  provide  for  level  monthly  payments  in an  amount
sufficient fully to amortize the Mortgage Loans over their terms or, in the case
of adjustable rate Mortgage Loans,  monthly payments that will be adjusted to an
amount  that  will  amortize  such  Mortgage   Loans  fully  over  their  terms.
Approximately 24.88% of the Mortgage Loans, by aggregate principal balance as of
the Cut-off Date,  are balloon loans (the  "Balloon  Loans"),  which require the
related mortgagors to make balloon payments on the maturity date of such Balloon
Loans that are larger than the monthly payments made by such mortgagors on prior
due dates in order to  amortize  such  Balloon  Loans  fully over  their  terms.
Approximately 17.43% of the Mortgage Loans, by aggregate principal balance as of
the Cut-off  Date,  are interest  only loans (the  "Interest  Only Loans") which
require the related mortgagors to make monthly payments of only accrued interest
for the first five years following origination. After such interest-only period,
the mortgagor's  monthly payment will be recalculated to cover both interest and
principal  so that such  Mortgage  Loan will  amortize  fully on or prior to its
final payment date.

      Approximately 95.11% of the Mortgage Loans, by aggregate principal balance
as of the  Cut-off  Date,  are secured by first  mortgages  or deeds of trust or
other  similar  security   instruments   creating  first  liens  on  residential
properties  ("First Lien Mortgage Loans").  Approximately  4.89% of the Mortgage
Loans,  by aggregate  principal  balance as of the Cut-off Date,  are secured by
second  mortgages  or  deeds of trust  or  other  similar  security  instruments
creating second liens on residential  properties ("Second Lien Mortgage Loans").
The  Mortgaged  Properties  generally  consist  of  attached,  detached  or semi
detached,  one-to-four  family dwelling  units,  individual  condominium  units,
individual units in planned unit developments and manufactured housings.

      References to percentages of the Mortgage Loans,  unless  otherwise noted,
are calculated based on the aggregate principal balance of the Mortgage Loans as
of the Cut-off Date.

      The mortgage rate (the  "Mortgage  Rate") on each Mortgage Loan is the per
annum rate of  interest  specified  in the related  mortgage  note as reduced by
application  of the  Relief Act or  similar  state or local laws and  bankruptcy
adjustments.  Approximately 16.01% of the Mortgage Loans are fixed-rate mortgage
loans  and  approximately  83.99%  of the  Mortgage  Loans  are  adjustable-rate
mortgage  loans.  The  adjustable-rate  mortgage  loans are  referred to in this
prospectus  supplement  as  "ARM  Loans".  All  of the  ARM  Loans  provide  for
semi-annual  adjustment  to the  Mortgage  Rates  applicable  thereto  based  on
Six-Month LIBOR (as described below).  The first adjustment with respect to each
ARM Loan will not occur  until  after an  initial  period of two,  three or five
years from the date of origination  thereof  (each, a "Delayed First  Adjustment
Mortgage Loan"). In connection with each Mortgage Rate adjustment, the ARM Loans
have corresponding  adjustments to their monthly payment amount, in each case on
each applicable  adjustment date (each such date, an "Adjustment  Date").  As to
each  Mortgage  Loan,  the Servicer  will be  responsible  for  calculating  and
implementing  Mortgage Rate  adjustments.  On each Adjustment Date, the Mortgage
Rate on each ARM Loan will be adjusted  generally  to equal the sum of Six-Month
LIBOR and a fixed  percentage  amount  (the  "Gross  Margin")  for that ARM Loan
specified in the related  mortgage  note.  The  Mortgage  Rate on each ARM Loan,
however,  including  each  Delayed  First  Adjustment  Mortgage  Loan,  will not
increase or decrease by more than the initial  periodic  rate cap (the  "Initial


                                      S-23


Periodic  Rate Cap")  specified  in the  related  mortgage  note on the  initial
Adjustment  Date or increase or  decrease by more than the  subsequent  periodic
rate cap (the "Subsequent  Periodic Rate Cap") specified in the related mortgage
note on any subsequent  Adjustment Date and will not exceed a specified  maximum
mortgage rate (the "Maximum  Mortgage Rate") over the life of the ARM Loan or be
less than a specified  minimum mortgage rate (the "Minimum  Mortgage Rate") over
the life of the ARM Loan.  The weighted  average  Initial  Periodic Rate Cap and
Subsequent Periodic Rate Cap for the ARM Loans is approximately 2.964% per annum
and 1.005% per annum, respectively. Effective with the first monthly payment due
on each ARM Loan after each related  Adjustment Date, the monthly payment amount
will be adjusted to an amount that will fully amortize the outstanding principal
balance of the related ARM Loan over its remaining  term and pay interest at the
Mortgage Rate as so adjusted.  Due to the  application of the Periodic Rate Caps
and the Maximum  Mortgage Rates, the Mortgage Rate on each ARM Loan, as adjusted
on any  related  Adjustment  Date,  may  be  less  than  the  sum of the  Index,
calculated  as described in this  prospectus  supplement,  and the related Gross
Margin. See "--The Index" in this prospectus  supplement.  None of the ARM Loans
permit the related mortgagor to convert the adjustable  Mortgage Rate thereon to
a fixed Mortgage Rate.

      Substantially  all of the Mortgage Loans have scheduled  monthly  payments
due on the first day of the month (with respect to each Mortgage  Loan, the "Due
Date"). Each Mortgage Loan will contain a customary  "due-on-sale"  clause which
provides  that the  Mortgage  Loan  must be  repaid at the time of a sale of the
related Mortgaged Property or assumed by a creditworthy purchaser of the related
Mortgaged Property.

      Approximately  76.19% of the  Mortgage  Loans  provide  for payment by the
mortgagor  of  a   prepayment   charge  (a   "Prepayment   Charge")  in  limited
circumstances  on certain  prepayments as provided in the related mortgage note.
Each such Mortgage  Loan provides for payment of a Prepayment  Charge on certain
partial  prepayments and all prepayments in full made within a certain period of
time from the date of  origination  of the  Mortgage  Loan,  as  provided in the
related mortgage note. The amount of the Prepayment Charge is as provided in the
related mortgage note. The holders of the Class P Certificates  will be entitled
to all Prepayment Charges received on the Mortgage Loans, and these amounts will
not be available for  distribution on the other classes of  certificates.  Under
the limited  instances  described  under the terms of the pooling and  servicing
agreement,  the  servicer  may waive the  payment  of any  otherwise  applicable
Prepayment  Charge with  respect to the related  Mortgage  Loans.  As of July 1,
2003, the  Alternative  Mortgage  Parity Act of 1982 (the "Parity  Act"),  which
regulates the ability of originators to impose prepayment charges,  was amended,
and as a result, the originators will be required to comply with state and local
laws in  originating  mortgage  loans with  prepayment  charge  provisions  with
respect to loans  originated on or after July 1, 2003.  The  Depositor  makes no
representations  as to the effect that the prepayment  charges and the amendment
of the Parity Act may have on the prepayment  performance of the Mortgage Loans.
However,  the  amendment of the Parity Act does not  retroactively  affect loans
originated  before July 1, 2003.  Investors should conduct their own analysis of
the effect, if any, that the Prepayment Charges,  decisions by the servicer with
respect to the waiver of the Prepayment  Charges and the amendment to the Parity
Act, may have on the prepayment performance of the Mortgage Loans. The Depositor
makes no representation as to the effect that the Prepayment Charges,  decisions
by the  servicer  with respect to the waiver of the  Prepayment  Charges and the
amendment  to the Parity  Act,  may have on the  prepayment  performance  of the
Mortgage  Loans.  See "Certain  Legal  Aspects of the Mortgage  Loans-Prepayment
Charges and Late Fees; Debt-Acceleration Clauses" in the prospectus.

      In  addition,  the  servicer  may waive the  collection  of any  otherwise
applicable  Prepayment  Charge,  but only if: (1) such  waiver is  standard  and
customary in servicing  similar  Mortgage  Loans and such waiver is related to a
default or reasonably  foreseeable default and would, in the reasonable judgment
of the  servicer  maximize  recovery of total  proceeds  taking into account the
value of such  Prepayment  Charge and the  related  Mortgage  Loan and,  if such
waiver is made in


                                      S-24


connection with a refinancing of the related  Mortgage Loan, such refinancing is
related to a default or a reasonably  foreseeable default,  (ii) such Prepayment
Charge is  unenforceable  in accordance with applicable law or the collection of
such related  Prepayment Charge would otherwise violate  applicable law or (iii)
the  collection  of such  Prepayment  Charge  would  be  considered  "predatory"
pursuant to written  guidance  published  or issued by any  applicable  federal,
state or local regulatory  authority acting in its official  capacity and having
jurisdiction over such matters.

      No Mortgage  Loan will be more than 60 days  delinquent  as of the Cut-off
Date. A Mortgage Loan is  considered to be delinquent  when a payment due on any
due date  remains  unpaid as of the close of business on the last  business  day
immediately  prior to the next monthly due date. The determination as to whether
a Mortgage  Loan falls into this category is made as of the close of business on
the last business day of each month.

      The following  table sets forth the historical  delinquency  experience of
the Mortgage  Loans.  The  historical  delinquency  information  is based on the
delinquency  of each such  Mortgage Loan since the  origination  of the Mortgage
Loan.

MORTGAGE LOAN CHARACTERISTICS

      The average  principal  balance of the Mortgage Loans at  origination  was
approximately  $201,572. No Mortgage Loan had a principal balance at origination
greater than approximately  $1,550,000 or less than approximately  $15,000.  The
average  principal  balance of the  Mortgage  Loans as of the  Cut-off  Date was
approximately  $201,246.  No  Mortgage  Loan had a  principal  balance as of the
Cut-off Date greater than  approximately  $1,550,000 or less than  approximately
$14,833.

      The Mortgage  Loans had Mortgage Rates as of the Cut-off Date ranging from
approximately  5.500% per annum to  approximately  14.150%  per  annum,  and the
weighted  average  Mortgage Rate was  approximately  8.316% per annum. As of the
Cut-off Date, the ARM Loans had Gross Margins ranging from approximately  3.000%
per annum to  approximately  10.450% per annum,  Minimum  Mortgage Rates ranging
from  approximately  4.740%  per annum to  approximately  12.550%  per annum and
Maximum  Mortgage  Rates  ranging  from   approximately   9.200%  per  annum  to
approximately  18.990% per annum.  As of the Cut-off Date, the weighted  average
Gross Margin was approximately 6.453% the weighted average Minimum Mortgage Rate
was  approximately  8.160% per annum and the weighted  average Maximum  Mortgage
Rate was  approximately  14.208% per annum.  The latest  first  Adjustment  Date
following  the  Cut-off  Date on any ARM Loan  occurs  on March 1,  2011 and the
weighted  average next  Adjustment  Date for all of the ARM Loans  following the
Cut-off Date is April 5, 2008.


                                      S-25


      The weighted average combined loan-to-value ratio of the Mortgage Loans at
origination was  approximately  79.70%.  At origination,  no Mortgage Loan had a
combined  loan-to-value  ratio greater than  approximately  100.00% or less than
approximately 8.18%.

      The weighted  average  remaining  term to stated  maturity of the Mortgage
Loans was  approximately 356 months as of the Cut-off Date. None of the Mortgage
Loans will have a first due date prior to July 1, 2005 or after April 1, 2006 or
will have a remaining term to stated maturity of less than 173 months or greater
than 358 months as of the Cut-off Date. The latest maturity date of any Mortgage
Loan is March 1, 2036.

GROUP IA MORTGAGE LOAN CHARACTERISTICS

      Approximately  11.15%  of the  Group  IA  Mortgage  Loans  are  fixed-rate
mortgage loans and  approximately  88.85% of the Group IA Mortgage Loans are ARM
Loans (the "Group IA ARM Loans"),  in each case, by aggregate  principal balance
of the Group IA Mortgage Loans as of the Cut-off Date.

      Approximately  100.00%  of the Group IA  Mortgage  Loans  are  First  Lien
Mortgage  Loans,  in each case, by aggregate  principal  balance of the Group IA
Mortgage Loans as of the Cut-off Date.

Approximately  21.48%  of the Group IA  Mortgage  Loans  are  Balloon  Loans and
approximately  17.52% of the Group IA Mortgage Loans are Interest Only Loans, in
each case, by aggregate  principal  balance of the Group IA Mortgage Loans as of
the Cut-off Date.

      The  average   principal  balance  of  the  Group  IA  Mortgage  Loans  at
origination  was  approximately  $200,788.  No  Group  IA  Mortgage  Loan  had a
principal  balance at origination  greater than  approximately  $697,500 or less
than  approximately  $50,000.  The  average  principal  balance  of the Group IA
Mortgage Loans as of the Cut-off Date was  approximately  $200,453.  No Group IA

THE INDEX

      As of any Adjustment  Date, the index  applicable to the  determination of
the  Mortgage  Rate on each  ARM  Loan  will  generally  be the  average  of the
interbank  offered  rates for six-month  United  States  dollar  deposits in the
London  market as  published  in THE WALL STREET  JOURNAL  and as most  recently
available  either  (i) as of the  first  business  day 45  days  prior  to  that
Adjustment  Date or (ii) as of the first business day of the month preceding the
month  of the  Adjustment  Date,  as  specified  in the  related  mortgage  note
("Six-Month  LIBOR"  or the  "Index").  In the  event  that  the  Index  becomes
unavailable  or otherwise  unpublished,  the  servicer  will select a comparable
alternative  index  over  which it has no direct  control  and which is  readily
verifiable.

UNDERWRITING STANDARDS

      OPTION ONE MORTGAGE CORPORATION. The information set forth in this section
(other than the immediately following paragraph) with regard to the underwriting
standards of Option One Mortgage  Corporation ("Option One" or the "Originator")
has been provided to the Depositor by Option One.

      All of the  Mortgage  Loans will be acquired  on the  Closing  Date by the
Depositor  from the  Sponsor and were  acquired  by the Sponsor  from Option One
prior to the Closing Date.

      All  of  the  Mortgage  Loans  will  have  been  originated  generally  in
accordance  with  the  Option  One  Guidelines  (the  "Option  One  Underwriting
Guidelines").  The following is a general summary of the Option One Underwriting
Guidelines as generally applied, with some variation by Option One. This summary
does not purport to be a complete  description of the underwriting  standards of
Option One.

      The Option One  Underwriting  Guidelines are primarily  intended to assess
the value of the mortgaged  property,  to evaluate the adequacy of such property
as  collateral  for the mortgage loan and to assess the  applicant's  ability to
repay the mortgage loan.  The Mortgage  Loans were also  generally  underwritten
with a view toward resale in the secondary market.  The Mortgage Loans generally
bear  higher  rates of  interest  than  mortgage  loans that are  originated  in
accordance with customary Fannie Mae and Freddie Mac standards.

      On a  case-by-case  basis,  exceptions  to  the  Option  One  Underwriting
Guidelines are made where  compensating  factors exist.  Except as  specifically
stated  herein,  the Option One  Underwriting  Guidelines are the same for first
lien mortgage loans and second lien mortgage loans.

      Each  mortgage  loan  applicant  completes an  application  that  includes
information with respect to the applicant's liabilities, income, credit history,
employment  history  and  personal  information.  The  Option  One  Underwriting
Guidelines  require a credit  report and, if  available,  a credit score on each
applicant from a  credit-reporting  agency. The credit report typically contains
information  relating to such matters as credit  history with local and national
merchants  and lenders,  installment  debt  payments and any record of defaults,
bankruptcies,  repossessions  or  judgments.  A credit  score  is a  statistical
ranking of likely future credit  performance  developed by Fair,  Isaac and Co.,
Inc.   and   made   available   through   the   three   national   credit   data
repositories--Equifax, TransUnion and Experian.

      Mortgaged  properties  that are to secure  mortgage  loans  generally  are
appraised by  qualified  independent  appraisers.  Such  appraisers  inspect and
appraise  the subject  property and verify that such  property is in  acceptable
condition.  Following  each  appraisal,  the  appraiser  prepares a report which
includes a market value  analysis  based on recent sales of comparable  homes in
the area and, when deemed  appropriate,  replacement  cost analysis based on the
current


                                      S-72


cost of  constructing  a similar home. All appraisals are required to conform to
the  Uniform  Standards  of  Professional  Appraisal  Practice  adopted  by  the
Appraisal Standards Board of the Appraisal Foundation and are generally on forms
acceptable to Fannie Mae and Freddie Mac.

      The Option One  Underwriting  Guidelines  require that  mortgage  loans be
underwritten in a standardized  procedure which complies with applicable federal
and state laws and  regulations  and require  Option  One's  underwriters  to be
satisfied  that the value of the  property  being  financed,  as indicated by an
appraisal supports the loan balance.  The maximum loan amount for mortgage loans
originated under the origination  programs varies by state and may be originated
up to $1,400,000.  Option One recognizes  that an appraised  value is an opinion
and  thus,  allows  for  variances  to the  appraisal  based on a review of such
appraisal,  the loan-to-value ratio ("LTV") and other risk factors.  The maximum
variance  between the  appraisal and a review of the appraisal is limited to (i)
10% for LTVs that are less than or equal to 85%, (ii) 5% for LTVs between 85.01%
and 95%, and (iii) 3% for LTVs over 95%. References to LTV's in this section are
based on loan balance  (including the principal  balance of the senior lien when
referring  to a second  lien  mortgage  loan)  relative  to (a) in the case of a
purchase money  mortgage  loan,  the lesser of the appraised  value or the sales
price of the  related  mortgaged  property  and (b) in the  case of a  refinance
mortgage loan, the appraised value.  There can be no assurance that the value of
a mortgaged property estimated in any appraisal or review is equal to the actual
value of such  mortgaged  property  at the  time of such  appraisal  or  review.
Furthermore,  there can be no  assurance  that the actual  value of a  mortgaged
property has not declined subsequent to the time of such appraisal or review.

      Option One Underwriting  Guidelines require a reasonable  determination of
an  applicant's  ability  to repay the loan.  Such  determination  is based on a
review  of  the   applicant's   source  of   income,   calculation   of  a  debt
service-to-income  ratio based on the amount of income from sources indicated on
the loan  application  or  similar  documentation,  a review of the  applicant's
credit history and the type and intended use of the property being financed.

      Except with  respect to the No  Documentation  program  that is  described
below, the Option One Underwriting Guidelines require verification or evaluation
of the income of each applicant and, for purchase transactions,  verification of
the seasoning or source of funds (in excess of $2,500)  required to be deposited
by the applicant  into escrow.  The income  verification  required  under Option
One's various mortgage loan programs is as follows:

      Full Documentation,  the highest level of income documentation,  generally
requires applicants to submit one written form of verification from the employer
of stable income for at least 12 months.  A wage-earner may document income by a
current pay stub reflecting year to date income and applicant's  most recent W-2
or IRS Form 1040. A self-employed  applicant may document income with either the
most recent federal tax returns or personal bank statements.

      Lite  Documentation  is for  applicants  who  otherwise  cannot  meet  the
requirements of the full documentation program and requires applicants to submit
3 months' bank statements or a paystub as verification of income.

      Stated Income  Documentation  applicants are qualified  based upon monthly
income as stated on the mortgage loan application.

      No Documentation, which is only available under the AA+ credit grade, does
not require any statement or proof of income,  employment or assets.  The credit
decision is based on the borrower's credit score and credit trade lines.

      For wage  earning  borrowers,  all  documentation  types  require a verbal
verification of employment to be conducted within 48 hours prior to funding.


                                      S-73


      LATITUDE ADVANTAGE PROGRAM. The majority of Option One's loan originations
are underwritten using its "Latitude  Advantage" program  guidelines.  Under the
Latitude  Advantage  program,  the maximum LTV is based on an applicant's credit
score, risk grade,  income  documentation and use and type of property.  Maximum
LTV for Full  Documentation  loans are generally higher than the maximum LTV for
corresponding  Lite  Documentation  or Stated Income loans.  The maximum LTV for
loans secured by  owner-occupied  properties are generally higher than for loans
secured by  properties  that are not  owner-occupied.  The credit  report of the
applicant whose credit score is being used for qualifying  purposes must reflect
three or more tradelines. A minimum credit score of 500 is required,  although a
credit score  greater than 580 is often  required to qualify for the maximum LTV
(100%) under the program.  The debt-to-income  ratio is generally less than 55%.
Latitude Advantage guidelines require  bankruptcies be discharged,  dismissed or
paid off at or prior to funding.  Collections  and judgments which are less than
12 months old and greater  than $5,000 must be paid down or paid off at or prior
to  closing.  Collections  and  judgments  which are 12 or more  months  old are
disregarded.  Under the Latitude Advantage  program,  Option One has established
six risk  grades,  "AA+" to "CC",  based on the  applicant's  previous  mortgage
payment history.  Under the AA+ risk category, the applicant must have no 30-day
late mortgage  payments  within the last 12 months.  Under the AA risk category,
the applicant must have no more than one 30 day late mortgage payment within the
past 12 months or no prior mortgage payment history. Under the A risk grade, the
applicant  must have no more than two 30-day late mortgage  payments  within the
past 12 months.  Under the B risk grade,  the  applicant  must have no more than
four 30-day late  mortgage  payments or two 30-day and one 60-day late  mortgage
payment  within the past 12 months.  Under the C risk grade,  the applicant must
have no more than six 30-day late  mortgage  payments,  one 60-day late mortgage
payment and one 90-day late mortgage  payment within the past 12 months,  or six
30-day late mortgage  payments,  two 60-day late mortgage payments and no 90-day
late  payments  within the last 12 months.  CC risk mortgage  delinquencies  are
considered on a case-by-case basis.

      Within the Latitude Advantage program,  the Score Advantage feature allows
the use of the co-applicant's  credit score for qualifying  purposes;  provided,
however,  to the extent the  co-applicant's  credit  score  exceeds  the primary
applicant's  credit score by more than 100 points,  then the  qualifying  credit
score  will be the  primary  applicant's  credit  score plus 100  points.  Score
Advantage mortgage loans must be owner occupied, Full Documentation,  and have a
maximum LTV of 95%. Score Advantage requires the co-applicant's  contribution to
qualifying  income to be equal to or  greater  than 30% of the total  qualifying
income.  The maximum  debt-to-income  ratio for this program is 5% less than the
maximum debt-to-income ratio allowed under the corresponding non-Score Advantage
program.

      LEGACY PROGRAM. In addition to its credit score based origination program,
Latitude  Advantage,  Option One  offers  first lien  mortgage  loans  under the
"Legacy" program. Under the Legacy program, LTV limitations are determined based
on the  applicant's  risk  grade,  income  documentation  and  use  and  type of
property.  In general,  the maximum LTV  increases  with credit  quality and are
typically higher for Full Documentation loans and owner-occupied properties. The
maximum  debt-to-income  ratio is generally  less than 55% for AA, A, and B risk
grades,  and  less  than  60% for C and CC risk  grades.  If a  credit  score is
available, the minimum credit score required is 500.

      Option One has  established  five credit grades under the Legacy  program,
"AA" to "CC", and considers an applicant's  prior mortgage payment  history,  if
applicable, consumer credit payment history, bankruptcy and foreclosure history,
and debt-to-income  ratios when determining a loan's risk grade. The Legacy risk
grades correspond  directly with the Latitude Advantage risk grades with respect
to previous mortgage payment history requirements. In addition, under the Legacy
program no  foreclosures  may have occurred during the preceding three years for
AA credit  grade,  two years for A grade  and B grade  with a LTV  greater  than
80%,18  months for B grade with a LTV less than or equal to 80%, or one year for
C grade  applicants.  Chapter 7 and Chapter 11


                                      S-74


bankruptcies  may have  occurred  during  the  preceding  two years for AA and A
credit  grades and B grade with a LTV  greater  than 80%,  18 months for B grade
with a LTV  less  than or  equal  to 80%,  and one  year  for C  grade.  CC risk
bankruptcies are permitted if paid in full,  discharged or dismissed at or prior
to closing.  If an applicant's Chapter 13 bankruptcy has been discharged and the
applicant has a credit history otherwise complying with the credit parameters of
a credit grade and the mortgage  loan LTV is equal to or less than 80%, then the
applicant may qualify for such credit grade.

      EXCEPTIONS. As described above, the foregoing risk categories and criteria
are Underwriting  Guidelines only. On a case-by-case basis, it may be determined
that  an  applicant  warrants  a  debt-to-income  ratio  exception,   a  pricing
exception,  a loan-to-value  exception, a credit score exception or an exception
from certain  requirements  of a particular  risk  category.  An upgrade will be
granted if the application reflects certain compensating factors,  among others:
a  relatively  lower LTV; a maximum of one 30-day late  payment on all  mortgage
loans  during the last 12 months;  stable  employment;  a fixed source of income
that is greater than 50% of all income;  ownership of current  residence of four
or more years; or cash reserves equal to or in excess of three monthly  payments
of principal, interest, taxes and insurance. An upgrade or exception may also be
allowed if the applicant places a down payment through escrow of at least 10% of
the purchase  price of the  mortgaged  property,  or if the new loan reduces the
applicant's  monthly  aggregate  mortgage  payment by 20% or more.  Accordingly,
certain  mortgagors  may qualify  for a more  favorable  risk  category or for a
higher  maximum LTV that,  in the absence of such  compensating  factors,  would
satisfy only the criteria of a less favorable risk category or maximum LTV.

ADDITIONAL INFORMATION CONCERNING THE MORTGAGE LOANS

      The description in this prospectus supplement of the Mortgage Pool and the
Mortgaged  Properties is based upon the Mortgage Pool as  constituted  as of the
close of business on the Cut-off Date,  as adjusted for the scheduled  principal
payments due on or before such date. Prior to the issuance of the  certificates,
Mortgage  Loans may be removed from the Mortgage  Pool as a result of incomplete
documentation  or  otherwise  if the  Depositor  deems the removal  necessary or
desirable,  and may be prepaid at any time. A limited  number of other  mortgage
loans  may be  included  in the  Mortgage  Pool  prior  to the  issuance  of the
certificates  unless  including these mortgage loans would  materially alter the
characteristics of the Mortgage Pool as described in this prospectus supplement.
The  Depositor  believes  that the  information  set  forth  in this  prospectus
supplement will be representative of the characteristics of the Mortgage Pool as
it will be constituted  at the time the  certificates  are issued,  although the
range of Mortgage Rates and maturities and other characteristics of the Mortgage
Loans may vary.  If, as of the Closing Date,  any material  pool  characteristic
differs  by 5% or more  from  the  description  in this  prospectus  supplement,
revised  disclosure  will be provided  either in a supplement to this prospectus
supplement or in a Current Report on Form 8-K.

                            YIELD ON THE CERTIFICATES

GENERAL PREPAYMENT CONSIDERATIONS

      The rate of principal payments on the Offered Certificates,  the aggregate
amount of distributions  on such  certificates and the yield to maturity of such
certificates  will be related to the rate and timing of payments of principal on
the Mortgage Loans. The rate of principal payments on the Mortgage Loans will in
turn be affected by the  amortization  schedules of the  Mortgage  Loans as they
change from time to time to accommodate changes in the Mortgage Rates and by the
rate of principal  prepayments  thereon  (including  for this purpose,  payments
resulting from refinancings, liquidations of the Mortgage Loans due to defaults,
casualties,  condemnations and repurchases, whether optional or required, by the
Depositor, the Servicer or the Sponsor). The


                                      S-75


Mortgage  Loans  may be  prepaid  by the  mortgagors  at any time;  however,  as
described under "The Mortgage Pool" in this prospectus supplement,  with respect
to approximately 76.19% of the Mortgage Loans, by aggregate principal balance of
the Mortgage  Loans as of the Cut-off Date, a prepayment may subject the related
mortgagor to a Prepayment Charge.

      Prepayments,  liquidations  and  repurchases  of the  Mortgage  Loans will
result in  distributions  in respect of principal to the holders of the class or
classes of Offered  Certificates  then  entitled to receive  distributions  that
otherwise  would be distributed  over the remaining terms of the Mortgage Loans.
Since the rates of payment of  principal  on the  Mortgage  Loans will depend on
future  events and a variety of factors,  no  assurance  can be given as to that
rate or the rate of  principal  prepayments.  The  extent  to which the yield to
maturity  of any class of  Offered  Certificates  may vary from the  anticipated
yield  will  depend  upon the  degree  to which  the  Offered  Certificates  are
purchased  at a  discount  or  premium  and the  degree to which  the  timing of
payments thereon is sensitive to prepayments on the Mortgage Loans.  Further, an
investor should consider,  in the case of any Offered Certificate purchased at a
discount,  the risk that a slower than anticipated rate of principal payments on
the Mortgage Loans could result in an actual yield to the investor that is lower
than the anticipated yield. In the case of any Offered Certificate  purchased at
a premium,  there is a risk that a faster  than  anticipated  rate of  principal
payments  could result in an actual yield to the investor that is lower than the
anticipated yield. In general,  the earlier prepayments of principal are made on
the  Mortgage  Loans,  the  greater  the effect on the yield to  maturity of the
Offered  Certificates.  As a  result,  the  effect  on an  investors'  yield  of
principal  payments  occurring  at a  rate  higher  (or  lower)  than  the  rate
anticipated by the investor during the period immediately following the issuance
of the  Offered  Certificates  would not be fully  offset by a  subsequent  like
reduction (or increase) in the rate of principal payments.

      It is highly  unlikely that the Mortgage Loans will prepay at any constant
rate until  maturity or that all of the  Mortgage  Loans will prepay at the same
rate.   Moreover,   the  timing  of   prepayments  on  the  Mortgage  Loans  may
significantly affect the yield to maturity on the Offered Certificates,  even if
the average rate of principal payments  experienced over time is consistent with
an investor's expectation.

      The rate of payments (including prepayments) on pools of mortgage loans is
influenced by a variety of economic,  geographic,  social and other factors.  If
prevailing  mortgage  rates fall  significantly  below the Mortgage Rates on the
Mortgage  Loans,  the rate of prepayment  and  refinancing  would be expected to
increase.  Conversely, if prevailing mortgage rates rise significantly above the
Mortgage  Rates on the Mortgage  Loans,  the rate of  prepayment on the Mortgage
Loans would be expected to  decrease.  Other  factors  affecting  prepayment  of
mortgage  loans include  changes in mortgagors'  housing  needs,  job transfers,
unemployment,  mortgagors' net equity in the mortgaged  properties and servicing
decisions.  The prepayment  experience of the Delayed First Adjustment  Mortgage
Loans may  differ  from that of the other  Mortgage  Loans.  The  Delayed  First
Adjustment Mortgage Loans may be subject to greater rates of prepayments as they
approach their initial  Adjustment  Dates even if market interest rates are only
slightly higher or lower than the Mortgage Rates on the Delayed First Adjustment
Mortgage Loans as mortgagors seek to avoid changes in their monthly payments. In
addition,  the existence of the applicable  Periodic Rate Cap,  Maximum Mortgage
Rate and  Minimum  Mortgage  Rate  may  affect  the  likelihood  of  prepayments
resulting  from  refinancings.  There  can be no  certainty  as to the  rate  of
prepayments  on the  Mortgage  Loans  during  any period or over the life of the
certificates. See "Yield Considerations" in the prospectus.

      Because  principal  distributions  are paid to certain  classes of Offered
Certificates  before other classes,  holders of classes of Offered  Certificates
having a later priority of payment bear a greater risk of losses than holders of
classes having earlier priorities for distribution of principal. This is because
the certificates having a later priority of payment will represent an increasing
percentage   interest  in  the  trust  fund  during  the  period  prior  to  the
commencement of distributions


                                      S-76


of  principal on these  certificates.  As described  under  "Description  of the
Certificates--Principal  Distributions  on the  Offered  Certificates"  in  this
prospectus supplement, prior to the Stepdown Date, all principal payments on the
Mortgage  Loans will be allocated to the Class A  Certificates.  Thereafter,  as
further described in this prospectus supplement, during certain periods, subject
to certain  delinquency  triggers described in this prospectus  supplement,  all
principal  payments on the Mortgage  Loans will be  allocated  among the Class A
Certificates  and all classes of the Mezzanine  Certificates  in the  priorities
described under "Description of the Certificates--Principal Distributions on the
Offered Certificates" in this prospectus supplement.

      In general,  defaults on mortgage loans are expected to occur with greater
frequency in their early years.  In  addition,  default  rates may be higher for
mortgage  loans used to refinance an existing  mortgage  loan. In the event of a
mortgagor's  default on a Mortgage Loan, there can be no assurance that recourse
will be available beyond the specific Mortgaged Property pledged as security for
repayment.  See "The Mortgage  Pool--Underwriting  Standards" in this prospectus
supplement.

SPECIAL YIELD CONSIDERATIONS

      The  Mortgage  Rates on  approximately  16.01% of the Mortgage  Loans,  by
aggregate  principal balance as of the Cut-off Date, are fixed and will not vary
with any index.  The  Mortgage  Rates on  approximately  83.99% of the  Mortgage
Loans,  by  aggregate   principal   balance  as  of  the  Cut-off  Date,  adjust
semi-annually  based upon  Six-Month  LIBOR  subject to  periodic  and  lifetime
limitations and after an initial period of two, three or five years with respect
to Delayed First Adjustment Mortgage Loans. The Pass-Through Rate on the Offered
Certificates  adjusts  monthly  based  upon  One-Month  LIBOR,  subject  to  the
applicable  Net WAC  Pass-Through  Rate (as defined  under  "Description  of the
Certificates--Glossary"  in this  prospectus  supplement),  with the result that
increases  in the  Pass-Through  Rates on such  certificates  may be limited for
extended  periods in a rising interest rate  environment.  Investors should note
that all of the ARM Loans are  Delayed  First  Adjustment  Mortgage  Loans.  The
interest due on the Mortgage Loans during any Due Period, net of the expenses of
the trust and the  supplemental  interest trust  (including any Net Swap Payment
and any Swap  Termination  Payment  payable to the Swap  Provider  which was not
caused by the occurrence of a Swap Provider  Trigger  Event),  may not equal the
amount of interest  that would  accrue at  One-Month  LIBOR plus the  applicable
spread on the Offered  Certificates  during the related Interest Accrual Period;
however,  any  shortfall  of this kind will be  payable  to the  holders of such
certificates,  but  only  to the  extent  and in the  priority  described  under
"Description   of  the   Certificates--Overcollateralization   Provisions"   and
"Description of the Certificates--The  Interest Rate Swap Agreement and the Swap
Provider"  in this  prospectus  supplement.  In  addition,  Six-Month  LIBOR and
One-Month LIBOR may respond differently to economic and market factors. Thus, it
is possible,  for example, that if both One-Month LIBOR and Six-Month LIBOR rise
during the same period,  one-month  LIBOR may rise more  rapidly than  Six-Month
LIBOR,  potentially  resulting  in the  application  of the  applicable  Net WAC
Pass-Through Rate on the Offered Certificates,  which would adversely affect the
yield to maturity on such certificates.

      If the pass-through  rates on the Offered  Certificates are limited by the
applicable Net WAC Pass-Through  Rate for any  Distribution  Date, the resulting
interest  shortfalls,  which are  referred to herein as "Net WAC Rate  Carryover
Amounts",  may  be  recovered  by the  holders  of  such  certificates  on  such
Distribution  Date or on future  Distribution  Dates, to the extent that on such
Distribution  Date or future  Distribution  Dates there are any available  funds
remaining after certain other distributions on the Offered  Certificates and the
payment of certain fees and expenses of the trust and the supplemental  interest
trust  (including any Net Swap Payment payable to the Swap Provider and any Swap
Termination  Payment  payable to the Swap  Provider  which was not caused by the
occurrence  of a Swap  Provider  Trigger  Event).  The  ratings  on the  Offered
Certificates  will not  address  the  likelihood  of any such  recovery  of such
interest  shortfalls by holders of those  certificates  from amounts received or
advanced on the Mortgage Loans. In addition, any Net


                                      S-77


Swap Payment payable by the Swap Provider on any given Distribution Date will be
available to pay any Net WAC Rate  Carryover  Amounts  remaining  unpaid on such
Distribution  Date after taking into account any amounts paid in respect thereof
from collections, advances and other recoveries on the Mortgage Loans.

      As described under "Description of the Certificates--Allocation of Losses;
Subordination,"  amounts  otherwise  distributable  to holders of the  Mezzanine
Certificates  and the Class CE Certificates may be made available to protect the
holders of the Class A Certificates  against  interruptions in distributions due
to certain mortgagor  delinquencies,  to the extent not covered by P&I Advances.
Such   delinquencies  may  affect  the  yield  to  investors  in  the  Mezzanine
Certificates  and,  even if  subsequently  cured,  will affect the timing of the
receipt of  distributions  by the  holders  of the  Mezzanine  Certificates.  In
addition,  the rate of delinquencies or losses will affect the rate of principal
payments   on   the   Mezzanine   Certificates.    See   "Description   of   the
Certificates--Principal  Distributions  on the  Offered  Certificates"  in  this
prospectus supplement.

WEIGHTED AVERAGE LIVES

      Weighted  average  life  refers  to the  average  amount of time that will
elapse from the date of issuance of a security until each dollar of principal of
that security will be repaid to the investor.  The weighted  average life of the
Offered  Certificates  will be influenced by the rate at which  principal on the
Mortgage  Loans  is paid,  which  may be in the form of  scheduled  payments  or
prepayments (including repurchases and prepayments of principal by the mortgagor
as well as amounts received by virtue of condemnation,  insurance or foreclosure
with  respect to the  Mortgage  Loans),  and the timing of these  payments.  The
"Assumed Final Distribution Date" for each class of the Offered  Certificates is
the  Distribution  Date occurring in April 2036. The Assumed Final  Distribution
Date is the  Distribution  Date in the  month  following  the  latest  scheduled
maturity date of all of the Mortgage Loans. Since the rate of payment (including
prepayments)  of principal  on the Mortgage  Loans can be expected to exceed the
scheduled rate of payments, and could exceed the scheduled rate by a substantial
amount, the disposition of the last remaining Mortgage Loan may be earlier,  and
could be substantially earlier, than the Assumed Final Distribution Date.

      Prepayments  on  mortgage  loans  are  commonly  measured  relative  to  a
prepayment standard or model. The prepayment  assumption used in this prospectus
supplement  with  respect  to  the  adjustable-rate  Mortgage  Loans  assumes  a
prepayment  rate for the  mortgage  loans of 100% PPC.  To assume 100% PPC is to
assume (i) a per annum prepayment rate of 5% of the then  outstanding  principal
balance of the  mortgage  loans in the first  month of the life of the  mortgage
loans,  (ii) an  additional  2% per annum in each month  thereafter  through the
eleventh  month,  (iii) building to a constant  prepayment rate of 27% per annum
beginning in the twelfth month and  remaining  constant  until the  twenty-third
month, (iv) increasing to and remaining constant at a prepayment rate of 60% per
annum beginning in the twenty-fourth  month until the  twenty-seventh  month and
(v) decreasing and remaining constant at a prepayment rate of 30% per annum from
the twenty-eighth month and thereafter;  provided,  however, the prepayment rate
will not  exceed  85% per annum in any period  for any  percentage  of PPC.  The
prepayment  assumption  used in this  prospectus  supplement with respect to the
fixed-rate  Mortgage Loans assumes a prepayment rate of 100% PPC. To assume 100%
PPC is to assume (i) a per annum  prepayment rate of 4% of the then  outstanding
principal  balance of the  mortgage  loans in the first month of the life of the
mortgage loans, (ii) an additional approximate 1.72727% (precisely,  19%/11) per
annum in each month  thereafter  through the eleventh month and (iii) a constant
prepayment  rate of 23% per annum  beginning  in the  twelfth  month and in each
month thereafter during the life of the mortgage loans;  provided,  however, the
prepayment  rate will not exceed 85% per annum in any period for any  percentage
of PPC.  No  representation  is made  that the  Mortgage  Loans  will  prepay in
accordance with such prepayment  models or any other rate. We refer to each such
prepayment model herein as a "Prepayment Assumption".

      The tables  entitled  "Percent of Initial  Certificate  Principal  Balance
Outstanding at the Specified Percentages of the Prepayment  Assumption" indicate
the  percentage  of the  initial  Certificate  Principal  Balance of the Offered
Certificates  that would be outstanding after each of the dates shown at various
percentages  of PPC,  and the  corresponding  weighted  average  lives  of these
certificates.  The tables are based on the following  assumptions (the "Modeling
Assumptions"): (i) the Mortgage Pool consists of 270 assumed mortgage loans with
the  characteristics set forth below, (ii) distributions on the certificates are
received, in cash, on the 25th day of each month, commencing in June 2006; (iii)
the Mortgage Loans prepay at the percentages of PPC indicated;  (iv) no defaults
or delinquencies occur in the payment by mortgagors of principal and interest on
the Mortgage Loans and no shortfalls due to the application of the Relief Act or
similar  state  or local  laws are  incurred;  (v)  none of the  Depositor,  the
Servicer,  the Master Servicer or any other person purchases from the trust fund
any Mortgage Loan under any obligation or option under the pooling and servicing
agreement,  except as indicated in footnote  two in the tables;  (vi)  scheduled
monthly  payments on the  Mortgage  Loans are  received on the first day of each
month  commencing in June 2006,  and are computed  prior to giving effect to any
prepayments received in the prior month; (vii) prepayments  representing payment
in full of individual  Mortgage Loans are received on the last day of each month
commencing  in May 2006,  and  include  30 days'  interest  thereon;  (viii) the
scheduled  monthly  payment for each Mortgage  Loan is  calculated  based on the
assumed mortgage loan  characteristics  stated below;  (ix) the certificates are
purchased on, May 25, 2006; (x) Six-Month LIBOR remains  constant at 5.2813% per
annum and the gross mortgage rate on each ARM Loan is adjusted  according to the
assumed mortgage loan characteristics;  (xi) One-Month LIBOR remains constant at
5.0756% per annum;  (xii) the Class P Certificates have a Certificate  Principal
Balance  equal to zero;  (xiii) the fee payable to the Servicer is assumed to be
equal to equal to one-twelfth of the product of: (a)(1) for period  beginning in
May 2006 and ending in February  2007,  0.30%;  (2) for the period  beginning in
March 2007 and ending in October 2008, 0.40% and (3) for the period beginning in
November 2008 and thereafter, 0.65% and (b) the outstanding principal balance of
such Mortgage Loan per annum,  the fee payable to the Master Servicer is assumed
to be 0.004% per annum and the Credit Risk  Manager's fee is assumed to be equal
to 0.013% per annum and (xiv) the fixed swap  payment is  calculated  based on a
per annum rate of 5.28%.

      There will be  discrepancies  between  the  characteristics  of the actual
Mortgage Loans and the characteristics  assumed in preparing the tables entitled
"Percent of Initial  Certificate  Principal Balance Outstanding at the Specified
Percentages of the Prepayment  Assumption".  Any  discrepancy may have an effect
upon the percentages of the initial Certificate  Principal Balance  outstanding,
and the weighted  average lives,  of the Offered  Certificates  set forth in the
tables. In addition,  since the actual Mortgage Loans will have  characteristics
that  differ  from  those  assumed in  preparing  the tables and since it is not
likely the level of Six-Month  LIBOR or One-Month  LIBOR will remain constant as
assumed,  the Offered Certificates may mature earlier or later than indicated by
the   tables.   In   addition,   as   described   under   "Description   of  the
Certificates-Principal  Distributions  on  the  Offered  Certificates"  in  this
prospectus  supplement,  the  occurrence of the Stepdown Date or a Trigger Event
will have the effect of  accelerating or  decelerating  the  amortization of the
Offered Certificates, affecting the weighted average lives of such certificates.
Based on the foregoing  assumptions,  the tables  indicate the weighted  average
lives of each class of Offered Certificates and set forth the percentages of the
initial  Certificate  Principal  Balance  of such  certificates  that  would  be
outstanding after each of the Distribution  Dates shown, at various  percentages
of the  Prepayment  Assumption.  Neither  the  prepayment  model  used  in  this
prospectus  supplement nor any other prepayment model or assumption  purports to
be a historical  description  of  prepayment  experience  or a prediction of the
anticipated  rate of  prepayment  of any pool of mortgage  loans,  including the
Mortgage Loans.  Variations in the prepayment  experience and the balance of the
Mortgage  Loans that prepay may increase or decrease the  percentages of initial
Certificate  Principal  Balances,  and  weighted  average  lives,  shown  in the
following  tables.  These  variations  may occur even if the average  prepayment
experience of all the Mortgage Loans equals any of the specified  percentages of
the Prepayment Assumption.

- ----------
* If  applicable,  indicates  a number  that is greater  than zero but less than
0.5%.

(1) The weighted  average life of a certificate is determined by (a) multiplying
the amount of each  distribution  of  principal  by the number of years from the
date of issuance of the certificate to the related Distribution Date, (b) adding
the results and (c) dividing the sum by the aggregate amount of the distribution
of principal described in clause (a) above.

(2)  Assumes  that the Master  Servicer  exercises  its option to  purchase  the
Mortgage  Loans  on the  earliest  possible  Distribution  Date on  which  it is
permitted   to   exercise    this   option.    SEE   "POOLING   AND    SERVICING
AGREEMENT--TERMINATION" IN THIS PROSPECTUS SUPPLEMENT.


                                     S-106


      There is no assurance  that  prepayments of the Mortgage Loans included in
the Mortgage Pool will conform to any of the levels of the Prepayment Assumption
indicated in the immediately  preceding  tables,  or to any other level, or that
the actual weighted  average lives of the Class A Certificates and the Mezzanine
Certificates  will conform to any of the weighted average lives set forth in the
immediately  preceding  tables.  Furthermore,  the information  contained in the
tables with respect to the weighted  average  lives of the Class A  Certificates
and the Mezzanine  Certificates  is not  necessarily  indicative of the weighted
average lives that might be calculated or projected  under  different or varying
prepayment assumptions.

      The  characteristics  of the Mortgage Loans will differ from those assumed
in preparing the immediately  preceding tables. In addition, it is unlikely that
any Mortgage Loan will prepay at any constant  percentage until maturity or that
all of the Mortgage Loans will prepay at the same rate. The timing of changes in
the rate of prepayments may significantly affect the actual yield to maturity to
investors,  even if the average rate of principal prepayments is consistent with
the expectations of investors.

YIELD SENSITIVITY OF THE MEZZANINE CERTIFICATES

      If the Certificate  Principal  Balances of the Class CE, Class M-11, Class
M-10,  Class M-9,  Class M-8,  Class M-7, Class M-6, Class M-5, Class M-4, Class
M-3 and Class M-2 Certificates  have been reduced to zero, the yield to maturity
on the Class M-1 Certificates  will become extremely  sensitive to losses on the
Mortgage  Loans  (and the timing  thereof)  that are  covered by  subordination,
because the entire  amount of any Realized  Losses (to the extent not covered by
Net Monthly  Excess  Cashflow or by amounts  paid under the  Interest  Rate Swap
Agreement  and  available  for that  purpose) will be allocated to the Class M-1
Certificates. If the Certificate Principal Balances of the Class CE, Class M-11,
Class M-10, Class M-9, Class M-8, Class M-7, Class M-6, Class M-5, Class M-4 and
Class M-3  Certificates  have been reduced to zero, the yield to maturity on the
Class M-2 Certificates will become extremely sensitive to losses on the Mortgage
Loans (and the timing  thereof) that are covered by  subordination,  because the
entire  amount of any Realized  Losses (to the extent not covered by Net Monthly
Excess  Cashflow or by amounts paid under the Interest  Rate Swap  Agreement and
available for that purpose) will be allocated to the Class M-2 Certificates.  If
the  Certificate  Principal  Balances of the Class CE,  Class M-11,  Class M-10,
Class M-9, Class M-8, Class M-7, Class M-6, Class M-5 and Class M-4 Certificates
have been reduced to zero,  the yield to maturity on the Class M-3  Certificates
will become extremely  sensitive to losses on the Mortgage Loans (and the timing
thereof)  that are covered by  subordination,  because the entire  amount of any
Realized Losses (to the extent not covered by Net

Monthly  Excess  Cashflow  or by  amounts  paid  under  the  Interest  Rate Swap
Agreement  and  available  for that  purpose) will be allocated to the Class M-3
Certificates. If the Certificate Principal Balances of the Class CE, Class M-11,
Class  M-10,  Class  M-9,  Class  M-8,  Class  M-7,  Class  M-6  and  Class  M-5
Certificates  have been reduced to zero,  the yield to maturity on the Class M-4
Certificates  will become  extremely  sensitive to losses on the Mortgage  Loans
(and the timing thereof) that are covered by  subordination,  because the entire
amount of any Realized  Losses (to the extent not covered by Net Monthly  Excess
Cashflow or by amounts paid under the Interest Rate Swap Agreement and available
for that  purpose)  will be  allocated  to the  Class M-4  Certificates.  If the
Certificate  Principal  Balances of the Class CE, Class M-11,  Class M-10, Class
M-9, Class M-8, Class M-7 and Class M-6 Certificates  have been reduced to zero,
the yield to  maturity  on the  Class M-5  Certificates  will  become  extremely
sensitive  to losses on the  Mortgage  Loans (and the timing  thereof)  that are
covered by  subordination,  because the entire amount of any Realized Losses (to
the extent not covered by Net Monthly  Excess  Cashflow or by amounts paid under
the  Interest  Rate Swap  Agreement  and  available  for that  purpose)  will be
allocated to the Class M-5 Certificates.  If the Certificate  Principal Balances
of the Class CE,  Class  M-11,  Class M-10,  Class M-9,  Class M-8 and Class M-7
Certificates  have been reduced to zero,  the yield to maturity on the Class M-6
Certificates  will become  extremely  sensitive to losses on the Mortgage  Loans
(and the timing thereof) that are covered by  subordination,  because the entire
amount of any Realized  Losses (to the extent not covered by Net Monthly  Excess
Cashflow or by amounts paid under the Interest Rate Swap Agreement and available
for that  purpose)  will be  allocated  to the  Class M-6  Certificates.  If the
Certificate  Principal  Balances of the Class CE, Class M-11,  Class M-10, Class
M-9 and Class M-8 Certificates  have been reduced to zero, the yield to maturity
on the Class M-7 Certificates  will become extremely  sensitive to losses on the
Mortgage  Loans  (and the timing  thereof)  that are  covered by  subordination,
because the entire  amount of any Realized  Losses (to the extent not covered by
Net Monthly  Excess  Cashflow or by amounts  paid under the  Interest  Rate Swap
Agreement  and  available  for that  purpose) will be allocated to the Class M-7
Certificates. If the Certificate Principal Balances of the Class CE, Class M-11,
Class M-10 and Class M-9  Certificates  have been reduced to zero,  the yield to
maturity on the Class M-8 Certificates will become extremely sensitive to losses
on  the  Mortgage   Loans  (and  the  timing   thereof)   that  are  covered  by
subordination,  because the entire amount of any Realized  Losses (to the extent
not covered by Net Monthly Excess Cashflow or by amounts paid under the Interest
Rate Swap  Agreement  and  available  for that purpose) will be allocated to the
Class M-8 Certificates.  If the Certificate  Principal Balances of the Class CE,
Class M-11 and Class M-10  Certificates  have been reduced to zero, the yield to
maturity on the Class M-9 Certificates will become extremely sensitive to losses
on  the  Mortgage   Loans  (and  the  timing   thereof)   that  are  covered  by
subordination,  because the entire amount of any Realized  Losses (to the extent
not covered by Net Monthly Excess Cashflow or by amounts paid under the Interest
Rate Swap  Agreement  and  available  for that purpose) will be allocated to the
Class M-9 Certificates.  If the Certificate  Principal  Balances of the Class CE
Certificates and Class M-11 Certificates have been reduced to zero, the yield to
maturity on the Class M-10  Certificates  will  become  extremely  sensitive  to
losses on the  Mortgage  Loans  (and the  timing  thereof)  that are  covered by
subordination,  because the entire amount of any Realized  Losses (to the extent
not covered by Net Monthly Excess Cashflow or by amounts paid under the Interest
Rate Swap  Agreement  and  available  for that purpose) will be allocated to the
Class M-10  Certificates.  If the Certificate  Principal Balance of the Class CE
Certificates  has been reduced to zero,  the yield to maturity on the Class M-11
Certificates  will become  extremely  sensitive to losses on the Mortgage  Loans
(and the timing thereof) that are covered by  subordination,  because the entire
amount of any Realized  Losses (to the extent not covered by Net Monthly  Excess
Cashflow or by amounts paid under the Interest Rate Swap Agreement and available
for that purpose) will be allocated to the Class M-11 Certificates.  The initial
undivided  interests in the trust fund  evidenced  by the Class M-1,  Class M-2,
Class M-3,  Class M-4,  Class M-5,  Class M-6,  Class M-7, Class M-8, Class M-9,
Class  M-10,  Class  M-11 and Class CE  Certificates  are  approximately  3.45%,
approximately  3.10%,  approximately 1.85%,  approximately 1.65%,  approximately
1.65%,   approximately   1.45%,   approximately   1.45%,   approximately  1.30%,
approximately 1.00%,  approximately 0.55%, approximately 1.00% and approximately
2.10%,  respectively.  Investors  in the  Mezzanine  Certificates  should  fully
consider the risk that Realized Losses on the Mortgage Loans could result in the
failure of investors to fully recover their investments.  In addition, except as
otherwise  provided in this  prospectus  supplement  under  "Description  of the
Certificates--Allocation of Losses", once Realized Losses have been allocated to
the  Mezzanine  Certificates,  their  Certificate  Principal  Balances  will  be
permanently  reduced by the  amounts so  allocated.  Therefore,  the  amounts of
Realized Losses  allocated to the Mezzanine  Certificates  will no longer accrue
interest nor will these amounts be reinstated  (except in the case of subsequent
recoveries  as  described in this  prospectus  supplement).  However,  Allocated
Realized Loss Amounts may be paid to the holders of the  Mezzanine  Certificates
from Net Monthly  Excess  Cashflow and from payments  received by the Securities
Administrator  in respect of the Interest Rate Swap  Agreement in the priorities
set  forth  under   "Description   of  the   Certificates--Overcollateralization
Provisions"  and  "Description  of  the  Certificates--The  Interest  Rate  Swap
Agreement and the Swap Provider" in this prospectus supplement.

      Unless the Certificate Principal Balances of the Class A Certificates have
been reduced to zero, principal distributions on the Mezzanine Certificates will
only  commence  on or after the  Stepdown  Date and  during  periods  in which a
Trigger Event is not in effect.  As a result,  the weighted average lives of the
Mezzanine  Certificates  will be  longer  than  would  otherwise  be the


                                     S-108


case if  distributions of principal were allocated on a pro rata basis among all
of the Offered Certificates. As a result of the longer weighted average lives of
the Mezzanine Certificates, the holders of such certificates have a greater risk
of suffering a loss on their investments. For additional considerations relating
to the yield on the Mezzanine  Certificates,  see "Yield  Considerations" in the
prospectus.

                         DESCRIPTION OF THE CERTIFICATES

GENERAL

      The ACE Securities Corp. Home Equity Loan Trust,  Series  2006-OP1,  Asset
Backed Pass-Through Certificates will consist of twenty classes of certificates,
designated as (i) the Class A-1A Certificates; (ii) the Class A-1B Certificates;
(iii) the Class  A-2A,  Class  A-2B,  Class  A-2C and  Class  A-2D  Certificates
(collectively,  the "Class A-2  Certificates";  and together with the Class A-1A
Certificates and the Class A-1B Certificates, the "Class A Certificates");  (iv)
the Class M-1, Class M-2, Class M-3, Class M-4, Class M-5, Class M-6, Class M-7,
Class M-8, Class M-9, Class M-10 and Class M-11 Certificates (collectively,  the
"Mezzanine Certificates"); (v) the Class CE Certificates (collectively, with the
Mezzanine  Certificates,  the  "Subordinate  Certificates");  (vi)  the  Class P
Certificates; and (vii) the Class R Certificates (also referred to herein as the
"Residual  Certificates").  Only  the  Class A  Certificates  and the  Mezzanine
Certificates  (collectively,  the  "Offered  Certificates")  are offered by this
prospectus supplement.

      Distributions on the Offered  Certificates will be made on the 25th day of
each  month,  or,  if that day is not a  business  day,  on the next  succeeding
business  day,  beginning  in June  2006 to the  persons  in  whose  names  such
certificates  are  registered  at the close of business on the Record Date.  The
"Record Date" for the Class A Certificates  and the Mezzanine  Certificates  and
any   Distribution   Date  is  the  business  day  immediately   preceding  such
Distribution  Date, for so long as such Certificates are held in book-entry form
and the last business day of the month immediately  preceding the month in which
the related  Distribution  Date occurs if such certificates are held in physical
form.

      The  certificates   represent  in  the  aggregate  the  entire  beneficial
ownership  interest in the trust fund consisting  primarily of the Mortgage Pool
of  conventional,  one- to  four-family,  first and second lien,  fixed-rate and
adjustable-rate  Mortgage Loans having original terms to maturity of not greater
than  approximately  30 years.  The Mortgage  Loans have an aggregate  principal
balance as of the Cut-off  Date of  approximately  $1,107,055,226,  subject to a
permitted  variance as described  under "The Mortgage  Pool" in this  prospectus
supplement.

      The Class A  Certificates  and the  Mezzanine  Certificates  will have the
initial  Certificate  Principal  Balance set forth in the table appearing on the
cover of this  prospectus  supplement.  The  Pass-Through  Rates on the  Offered
Certificates  will be calculated for each  Distribution  Date as described under
"--Pass-Through  Rates"  below.  The Class A  Certificates  evidence  an initial
aggregate  undivided  interest of  approximately  79.45% in the trust fund,  the
Class M-1,  Class M-2,  Class M-3,  Class M-4,  Class M-5, Class M-6, Class M-7,
Class  M-8,  Class  M-9,  Class  M-10 and  M-11  Certificates  evidence  initial
undivided interests of approximately 3.45%,  approximately 3.10%,  approximately
1.85%,   approximately   1.65%,   approximately   1.65%,   approximately  1.45%,
approximately  1.45%,  approximately 1.30%,  approximately 1.00%,  approximately
0.55%,  approximately  1.00%,  respectively,  in the trust fund and the Class CE
Certificates  evidence an initial undivided  interest of approximately  2.10% in
the trust fund.

BOOK-ENTRY CERTIFICATES

      The Offered  Certificates will be book-entry  Certificates (for so long as
they are registered in the name of the applicable depository or its nominee, the
"Book-Entry Certificates"). Persons


                                     S-109


acquiring  beneficial   ownership  interests  in  the  Book-Entry   Certificates
("Certificate  Owners") will hold such certificates through The Depository Trust
Company  ("DTC")  in the  United  States,  or  Clearstream  Banking  Luxembourg,
formerly  known  as  Cedelbank  SA  ("Clearstream"),  or  the  Euroclear  System
("Euroclear") in Europe, if they are participants of such systems  ("Clearstream
Participants" or "Euroclear Participants",  respectively), or indirectly through
organizations  which are Clearstream or Euroclear  Participants.  The Book-Entry
Certificates  will  be  issued  in one or  more  certificates  which  equal  the
aggregate  Certificate Principal Balance of such Certificates and will initially
be  registered  in the name of Cede & Co., the nominee of DTC.  Clearstream  and
Euroclear will hold omnibus  positions on behalf of their  participants  through
customers'  securities  accounts in Clearstream's  and Euroclear's  names on the
books of their respective depositories which in turn will hold such positions in
customers'  securities accounts in the depositories,  names on the books of DTC.
Citibank, N.A. will act as depository for Clearstream,  and JPMorgan Chase Bank,
N.A. will act as depository for Euroclear (in such capacities,  individually the
"Relevant Depository" and collectively the "European  Depositories").  Investors
may hold such  beneficial  interests in the Book-Entry  Certificates  in minimum
dollar  denominations  of  $25,000  and  integral  multiples  of $1.00 in excess
thereof.  Except as described below, no Certificate Owner acquiring a Book-Entry
Certificate (each, a "beneficial  owner") will be entitled to receive a physical
certificate representing such Certificate (a "Definitive  Certificate").  Unless
and until Definitive  Certificates  are issued,  it is anticipated that the only
"Certificateholder"  of the Offered  Certificates will be Cede & Co., as nominee
of DTC. Certificate Owners will not be  Certificateholders  as that term is used
in the pooling and servicing agreement. Certificate Owners are only permitted to
exercise  their  rights  indirectly  through DTC and  participants  of DTC ("DTC
Participants").

      The  Certificate  Owner's  ownership of a Book-Entry  Certificate  will be
recorded on the records of the brokerage firm, bank, thrift institution or other
financial  intermediary  (each, a "Financial  Intermediary")  that maintains the
Certificate   Owner's   account  for  such  purpose.   In  turn,  the  Financial
Intermediary's  ownership of such Book-Entry Certificate will be recorded on the
records of DTC (or of a participating  firm that acts as agent for the Financial
Intermediary,  whose interest will in turn be recorded on the records of DTC, if
the beneficial  owner's  Financial  Intermediary is not a DTC Participant and on
the records of Clearstream or Euroclear, as appropriate).

      Certificate  Owners will  receive all  distributions  of  principal of and
interest  on the  Book-Entry  Certificates  from  the  Securities  Administrator
through  DTC  and  DTC  Participants.  While  the  Book-Entry  Certificates  are
outstanding (except under the circumstances  described below),  under the rules,
regulations  and procedures  creating and affecting DTC and its operations  (the
"Rules"), DTC is required to make book-entry transfers among DTC Participants on
whose behalf it acts with respect to the Book-Entry Certificates and is required
to receive and  transmit  distributions  of  principal  of, and interest on, the
Book-Entry  Certificates.  DTC Participants and indirect  participants with whom
Certificate  Owners have accounts with respect to  Book-Entry  Certificates  are
similarly  required to make  book-entry  transfers and receive and transmit such
distributions on behalf of their  respective  Certificate  Owners.  Accordingly,
although  Certificate  Owners will not possess  certificates  representing their
respective  interests  in the  Book-Entry  Certificates,  the  Rules  provide  a
mechanism by which  Certificate  Owners will receive  distributions  and will be
able to transfer their interest.

      Certificate Owners will not receive or be entitled to receive certificates
representing their respective interests in the Book-Entry  Certificates,  except
under the limited  circumstances  described  below.  Unless and until Definitive
Certificates  are issued,  Certificate  Owners who are not DTC  Participants may
transfer ownership of Book-Entry  Certificates only through DTC Participants and
indirect   participants  by  instructing  such  DTC  Participants  and  indirect
participants  to  transfer  Book-Entry  Certificates,  by  book-entry  transfer,
through DTC for the account of the purchasers of such  Book-Entry  Certificates,
which account is maintained with their  respective DTC  Participants.  Under the
Rules and in accordance with DTC's normal procedures,  transfers of ownership of


                                     S-110


Book-Entry  Certificates  will be executed  through DTC and the  accounts of the
respective DTC Participants at DTC will be debited and credited.  Similarly, the
DTC Participants and indirect  participants will make debits or credits,  as the
case  may  be,  on  their  records  on  behalf  of the  selling  and  purchasing
Certificate Owners.

      Because  of time zone  differences,  credits  of  securities  received  in
Clearstream  or Euroclear as a result of a  transaction  with a DTC  Participant
will be made during subsequent  securities  settlement  processing and dated the
business day following the DTC settlement date. Such credits or any transactions
in such  securities  settled  during  such  processing  will be  reported to the
relevant  Euroclear  Participants or Clearstream  Participants  (each as defined
below) on such  business day.  Cash  received in  Clearstream  or Euroclear as a
result  of sales of  securities  by or  through  a  Clearstream  Participant  or
Euroclear  Participant to a DTC  Participant  will be received with value on the
DTC  settlement  date but  will be  available  in the  relevant  Clearstream  or
Euroclear  cash account only as of the business day following the DTC settlement
date. For information with respect to tax documentation  procedures  relating to
the  Certificates,  see  "Global  Clearance  and  Settlement  and  Documentation
Procedures-Certain U.S. Federal Income Tax Documentation  Requirements" in Annex
I hereto.

      Transfers  between  DTC  Participants  will occur in  accordance  with DTC
rules.  Transfers between  Clearstream  Participants and Euroclear  Participants
will occur in accordance with their respective rules and operating procedures.

      Cross-market  transfers  between  persons  holding  directly or indirectly
through DTC, on the one hand, and,  directly or indirectly  through  Clearstream
Participants or Euroclear Participants, on the other, will be effected in DTC in
accordance  with DTC  rules on  behalf of the  relevant  European  international
clearing  system  by  the  Relevant  Depository;   however,  such  cross  market
transactions  will require  delivery of  instructions  to the relevant  European
international  clearing system by the  counterparty in such system in accordance
with its rules and procedures  and within its  established  deadlines  (European
time). The relevant European  international  clearing system, if the transaction
meets its settlement  requirements,  will deliver  instructions  to the Relevant
Depository to take action to effect final settlement on its behalf by delivering
or receiving  securities  in DTC, and making or receiving  payment in accordance
with  normal  procedures  for  same  day  funds  settlement  applicable  to DTC.
Clearstream Participants and Euroclear Participants may not deliver instructions
directly to the European Depositories.

      DTC which is a New York-chartered limited purpose trust company,  performs
services for its DTC Participants,  some of which (and/or their representatives)
own DTC. In accordance with its normal procedures, DTC is expected to record the
positions held by each DTC Participant in the Book-Entry  Certificates,  whether
held for its own  account  or as a  nominee  for  another  person.  In  general,
beneficial ownership of Book-Entry  Certificates will be subject to the rules of
DTC, as in effect from time to time.

      Clearstream,  67 Bd  Grande-Duchesse  Charlotte,  L-1331  Luxembourg,  was
incorporated in 1970 as a limited company under  Luxembourg law.  Clearstream is
owned by banks, securities dealers and financial institutions, and currently has
about  100  shareholders,   including  U.S.  financial   institutions  or  their
subsidiaries.  No single entity may own more than five percent of  Clearstream's
stock.

      Clearstream is registered as a bank in Luxembourg,  and as such is subject
to regulation by the Institute Monetaire Luxembourgeois, the Luxembourg Monetary
Authority, which supervises Luxembourg banks.

      Clearstream  holds  securities  for  its  customers  and  facilitates  the
clearance and  settlement of securities  transactions  by electronic  book-entry
transfers between their accounts. Clearstream


                                     S-111


provides various services, including safekeeping,  administration, clearance and
settlement of  internationally  traded  securities  and  securities  lending and
borrowing.  Clearstream also deals with domestic  securities  markets in several
countries   through   established   depository   and  custodial   relationships.
Clearstream has established an electronic bridge with the Euroclear Operator (as
defined below) in Brussels to facilitate  settlement of trades between  systems.
Clearstream currently accepts over 70,000 securities issues on its books.

      Clearstream's  customers are world-wide financial  institutions  including
underwriters,  securities  brokers  and  dealers,  banks,  trust  companies  and
clearing  corporations.  Clearstream's  United  States  customers are limited to
securities   brokers  and  dealers  and  banks.   Currently,   Clearstream   has
approximately 3,000 customers located in over 60 countries,  including all major
European  countries,   Canada,  and  the  United  States.   Indirect  access  to
Clearstream is available to other institutions which clear through or maintain a
custodial relationship with an account holder of Clearstream.

      Euroclear was created in 1968 to hold securities for its  participants and
to  clear  and  settle  transactions  between  Euroclear   Participants  through
simultaneous electronic book-entry delivery against payment, thereby eliminating
the need for  physical  movement  of  certificates  and any  risk  from  lack of
simultaneous  transfers of securities and cash.  Transactions  may be settled in
any of 29  currencies,  including  United  States  dollars.  Euroclear  includes
various  other  services,   including   securities  lending  and  borrowing  and
interfaces with domestic markets in several  countries  generally similar to the
arrangements for cross-market  transfers with DTC described above.  Euroclear is
operated by the  Euroclear  Bank  S.A/N.V.  (the  "Euroclear  Operator"),  under
contract  with  Euroclear   Clearance   Systems  S.C.,  a  Belgian   cooperative
corporation (the  "Cooperative").  All operations are conducted by the Euroclear
Operator,  and all Euroclear  securities  clearance  accounts and Euroclear cash
accounts are accounts  with the Euroclear  Operator,  not the  Cooperative.  The
Cooperative   establishes   policy  for   Euroclear   on  behalf  of   Euroclear
Participants.  Euroclear  Participants  include banks (including central banks),
securities brokers and dealers and other professional financial  intermediaries.
Indirect access to Euroclear is also available to other firms that clear through
or  maintain a  custodial  relationship  with a  Euroclear  Participant,  either
directly or indirectly.

      Securities  clearance  accounts  and  cash  accounts  with  the  Euroclear
Operator are governed by the Terms and Conditions Governing Use of Euroclear and
the related Operating  Procedures of the Euroclear System and applicable Belgian
law (collectively,  the "Terms and Conditions"). The Terms and Conditions govern
transfers of securities and cash within Euroclear, withdrawals of securities and
cash from  Euroclear,  and receipts of payments  with respect to  securities  in
Euroclear.  All  securities  in Euroclear  are held on a fungible  basis without
attribution of specific  certificates to specific securities clearance accounts.
The  Euroclear  Operator acts under the Terms and  Conditions  only on behalf of
Euroclear  Participants,  and has no  record  of or  relationship  with  persons
holding through Euroclear Participants.

      Distributions  on  the  Book-Entry  Certificates  will  be  made  on  each
Distribution  Date by the  Securities  Administrator  to Cede & Co.  DTC will be
responsible  for  crediting  the amount of such  payments to the accounts of the
applicable DTC Participants in accordance with DTC's normal procedures. Each DTC
Participant  will be responsible for disbursing such payments to the Certificate
Owners of the Book-Entry  Certificates  that it represents and to each Financial
Intermediary for which it acts as agent.  Each such Financial  Intermediary will
be responsible for disbursing funds to the Certificate  Owners of the Book-Entry
Certificates that it represents.

      Under  a  book-entry   format,   Certificate   Owners  of  the  Book-Entry
Certificates may experience some delay in their receipt of payments,  since such
payments  will  be  forwarded  by the  Securities  Administrator  to  Cede & Co.
Distributions with respect to Certificates held through Clearstream or Euroclear
will be credited to the cash accounts of Clearstream Participants or


                                     S-112


Euroclear  Participants  in  accordance  with the  relevant  system's  rules and
procedures,   to  the  extent   received  by  the  Relevant   Depository.   Such
distributions  will be subject to tax  reporting  in  accordance  with  relevant
United  States  tax laws and  regulations.  SEE  "MATERIAL  FEDERAL  INCOME  TAX
CONSIDERATIONS  REMICS-TAXATION OF CERTAIN FOREIGN INVESTORS" IN THE PROSPECTUS.
Because DTC can only act on behalf of Financial Intermediaries, the ability of a
Certificate Owner to pledge Book-Entry  Certificates to persons or entities that
do not  participate  in the  Depository  system,  or  otherwise  take actions in
respect  of such  Book-Entry  Certificates,  may be  limited  due to the lack of
physical certificates for such Book-Entry Certificates. In addition, issuance of
the Book-Entry  Certificates in book-entry form may reduce the liquidity of such
Certificates in the secondary  market since certain  potential  investors may be
unwilling  to  purchase  Certificates  for which  they  cannot  obtain  physical
certificates.

      DTC has  advised  the  Securities  Administrator  that,  unless  and until
Definitive  Certificates  are issued,  DTC will take any action  permitted to be
taken by the  holders  of the  Book-Entry  Certificates  under the  pooling  and
servicing   agreement   only  at  the   direction  of  one  or  more   Financial
Intermediaries  to whose DTC accounts the Book-Entry  Certificates are credited,
to the extent that such actions are taken on behalf of Financial  Intermediaries
whose  holdings  include  such  Book-Entry  Certificates.   Clearstream  or  the
Euroclear Operator,  as the case may be, will take any other action permitted to
be taken by a  Certificateholder  under the pooling and  servicing  agreement on
behalf of a Clearstream  Participant or Euroclear Participant only in accordance
with its  relevant  rules and  procedures  and  subject  to the  ability  of the
Relevant  Depository  to effect such actions on its behalf  through DTC. DTC may
take actions, at the direction of the related DTC Participants,  with respect to
some Book-Entry  Certificates  which conflict with actions taken with respect to
other Book-Entry Certificates.

      Definitive  Certificates  will be  issued  to  Certificate  Owners  of the
Book-Entry Certificates,  or their nominees,  rather than to DTC or its nominee,
only if (a) DTC or the Depositor advises the Securities Administrator in writing
that DTC is no longer  willing,  qualified  or able to  discharge  properly  its
responsibilities  as nominee  and  depository  with  respect  to the  Book-Entry
Certificates  and the Depositor is unable to locate a qualified  successor,  (b)
the  Depositor,  at  its  sole  option,  with  the  consent  of  the  Securities
Administrator,  elects to terminate a book-entry system through DTC or (c) after
the  occurrence  of an Event of Default (as defined in the pooling and servicing
agreement),  Certificate Owners having percentage interests aggregating not less
than 51% of the Book-Entry Certificates advise the Securities  Administrator and
DTC through the Financial  Intermediaries  and the DTC  Participants  in writing
that  the  continuation  of a  book-entry  system  through  DTC (or a  successor
thereto) is no longer in the best interests of Certificate Owners.

      Upon the  occurrence  of any of the events  described  in the  immediately
preceding paragraph,  the Securities Administrator will be required to cause DTC
to  notify  all  Certificate  Owners  of the  occurrence  of such  event and the
availability  through DTC of Definitive  Certificates.  Upon surrender by DTC of
the global certificate or certificates  representing the Book-Entry Certificates
and instructions for  re-registration,  the Securities  Administrator will issue
Definitive  Certificates,  and  thereafter  the  Securities  Administrator  will
recognize  the holders of such  Definitive  Certificates  as  Certificateholders
under the pooling and servicing agreement.

      In the event any  Definitive  Certificates  are issued,  surrender of such
Definitive  Certificates  shall occur at the office designated from time to time
for such purposes by the  certificate  registrar.  As of the Closing  Date,  the
certificate  registrar  designates  its  offices  located  at Sixth  Street  and
Marquette Avenue, Minneapolis, Minnesota 55479 for this purpose.

      Although  DTC,  Clearstream  and  Euroclear  have agreed to the  foregoing
procedures in order to facilitate transfers of Book-Entry Certificates among DTC
Participants of DTC, Clearstream and Euroclear,  they are under no obligation to
perform or  continue  to perform  such  procedures  and such  procedures  may be
discontinued at any time.


                                     S-113


      None of the Depositor,  the Servicer,  the Master Servicer, the Securities
Administrator or the Trustee will have any  responsibility for any aspect of the
records  relating  to or  payments  made  on  account  of  beneficial  ownership
interests of the Book-Entry Certificates held by Cede & Co., as nominee for DTC,
or for  maintaining,  supervising  or  reviewing  any  records  relating to such
beneficial ownership interests or any transfers thereof.

THE INTEREST RATE SWAP AGREEMENT AND THE SWAP PROVIDER

      HSBC Bank USA, National Association as trustee (the "Supplemental Interest
Trust  Trustee")  on behalf of a separate  trust  created  under the pooling and
servicing  agreement  (the  "Supplemental  Interest  Trust")  will enter into an
interest rate swap agreement (the "Interest Rate Swap  Agreement")  with respect
to the  Offered  Certificates  with The Royal  Bank of  Scotland  plc (the "Swap
Provider").  The Interest Rate Swap Agreement  will be held in the  Supplemental
Interest  Trust.  The  Supplemental  Interest  Trust  Trustee  will  appoint the
Securities  Administrator  to receive and  distribute  funds with regards to the
Interest Rate Swap Agreement on behalf of the  Supplemental  Interest  Trust. On
each  Distribution  Date,  the  Securities  Administrator  will  deposit into an
account held in the  Supplemental  Interest  Trust (the  "Derivative  Account"),
certain amounts,  if any, received from the Swap Provider.  For the avoidance of
doubt,  the Supplemental  Interest Trust, the Interest Rate Swap Agreement,  and
the Derivative Account will not be assets of any REMIC.


                                     S-128


      The  significance  percentage  of the  Interest  Rate Swap  Agreement,  as
calculated in accordance  with Item 1115 of Regulation  AB, is less than 10%. As
provided in the Interest Rate Swap Agreement,  the Swap Provider may be replaced
in  certain  circumstances,  including  if the  significance  percentage  of the
Interest Rate Swap Agreement is equal to or greater than 10%.

      Pursuant to the Interest Rate Swap Agreement,  on each Distribution  Date,
(i) the Securities  Administrator (on behalf of the Supplemental  Interest Trust
and from funds of such trust) will be obligated to pay to the Swap  Provider,  a
fixed amount equal to the product of (x) 5.28%, (y) the Swap Notional Amount for
that  Distribution  Date set forth in the Interest Rate Swap Agreement and (z) a
fraction, the numerator of which is 30 (or, for the first Distribution Date, the
number  of days  elapsed  from  the  Closing  Date to but  excluding  the  first
Distribution  Date on a 30/360 basis),  and the denominator of which is 360 (the
"Securities  Administrator  Swap  Payment");  and (ii) the Swap Provider will be
obligated  to pay to the  Supplemental  Interest  Trust for the  benefit  of the
holders of the Offered  Certificates (the "Swap Provider  Payment"),  a floating
amount equal to the product of (x) one-month  LIBOR (as  determined  pursuant to
the  Interest  Rate  Swap  Agreement),  (y) the Swap  Notional  Amount  for that
Distribution  Date set  forth in the  Interest  Rate Swap  Agreement,  and (z) a
fraction,  the  numerator of which is the actual number of days elapsed from the
previous  Distribution Date to but excluding the current  Distribution Date (or,
for the first  Distribution  Date,  the actual  number of days  elapsed from the
Closing Date to but excluding the first Distribution  Date), and the denominator
of which is 360. A net payment will be required to be made on each  Distribution
Date  (each  such net  payment,  a "Net  Swap  Payment")  (a) by the  Securities
Administrator to the Swap Provider,  to the extent that the fixed amount exceeds
the corresponding floating amount, or (b) by the Swap Provider to the Securities
Administrator,  to the extent that the floating amount exceeds the corresponding
fixed  amount.  For each  Distribution  Date in respect of which the  Securities
Administrator  is required to make a Net Swap Payment to the Swap Provider,  the
trust will be required to make a payment to the Securities  Administrator in the
same amount.  Payments  received by the Supplemental  Interest Trust pursuant to
the Interest Rate Swap Agreement will be available for distributions of Interest
Carry Forward Amounts, Net WAC Rate Carryforward  Amounts,  amounts necessary to
maintain  or restore the  Required  Overcollateralization  Amount and  Allocated
Realized Loss Amounts.

      The  "Swap  Notional  Amount"  with  respect  to  each  Distribution  Date
commencing  in June 2006,  is set forth below (which will be  substantially  the
same schedule as set forth in the Interest Rate Swap Agreement).

      The Interest Rate Swap Agreement will terminate  immediately following the
Distribution Date in March 2010,  unless terminated  earlier upon the occurrence
of a Swap Default, an Early Termination Event or an Additional Termination Event
(each as defined below).

      The  respective  obligations  of the Swap  Provider  and the  Supplemental
Interest  Trust to pay  specified  amounts  due  under  the  Interest  Rate Swap
Agreement  will be subject to the following  conditions  precedent:  (1) no Swap
Default  or event  that with the giving of notice or lapse of time or both would
become a Swap Default,  in each case, in respect of the other party,  shall have
occurred and be continuing  with respect to the Interest Rate Swap Agreement and
(2) no "Early  Termination  Date" (as defined in the 1992 ISDA Master  Agreement
(Multicurrency-Cross  Border) which terms are  incorporated  by reference in the
Confirmation,  has occurred or been  effectively  designated with respect to the
Interest Rate Swap Agreement.

      "Events of Default" under the Interest Rate Swap  Agreement  (each a "Swap
Default") include the following:


                                     S-130


      o  "Failure  to Pay or  Deliver"  (as  amended in the  Interest  Rate Swap
Agreement),

      o "Bankruptcy" (as amended in the Interest Rate Swap Agreement), and

      o "Merger without Assumption" (only with respect to the Swap Provider),

      as described in the Interest Rate Swap Agreement.

      "Termination  Events"  under  the  Interest  Rate Swap  Agreement  (each a
"Termination Event") include the following:

      o "Illegality"  (which  generally  relates to changes in law causing it to
become unlawful for either party to perform its  obligations  under the Interest
Rate Swap Agreement),

      o "Tax Event"  (which  generally  relates to either  party to the Interest
Rate Swap  Agreement  receiving a payment under the Interest Rate Swap Agreement
from which an amount has been deducted or withheld for or on account of taxes or
payment of an additional  amount on account of an  indemnifiable  tax, in either
case generally resulting from a change in tax law) and

      o "Tax Event Upon Merger" (which generally  relates to either party to the
Interest  Rate Swap  Agreement  receiving a payment under the Interest Rate Swap
Agreement  from which an amount has been  deducted or withheld for or on account
of taxes or payment of an additional  amount on account of an indemnifiable  tax
resulting from a merger),

      as described in the Interest Rate Swap Agreement.  In addition,  there are
"Additional Termination Events" (as defined in the Interest Rate Swap Agreement)
including (i) if the Swap Provider fails to comply with the Downgrade Provisions
(as  defined  below),  (ii) if the  Swap  Provider  fails  to  comply  with  the
Regulation AB provisions  of the Interest  Rate Swap  Agreement,  or (iii) if an
optional  termination  occurs pursuant to the terms of the Pooling and Servicing
Agreement.

      Upon the  occurrence  of any Swap  Default  under the  Interest  Rate Swap
Agreement,  the  non-defaulting  party will have the right to designate an early
termination  date (an "Early  Termination  Date").  With respect to  Termination
Events (including Additional  Termination Events), an Early Termination Date may
be  designated  by one of the parties (as  specified in the  Interest  Rate Swap
Agreement) and will occur only upon notice and, in some circumstances, after any
affected  party  has  used  reasonable   efforts  to  transfer  its  rights  and
obligations  under the Interest Rate Swap Agreement to a related entity within a
specified  period after notice has been given of the Termination  Event,  all as
set forth in the Interest Rate Swap  Agreement.  In addition,  the Swap Provider
will have the right to designate an Early  Termination Date upon the delivery of
notice  indicating  the  intent  of the or the  master  servicer  or Ocwen  Loan
Servicing,  LLC to exercise its option to terminate the trust fund in accordance
with the Pooling and Servicing Agreement. The occurrence of an Early Termination
Date under the  Interest  Rate Swap  Agreement  will  constitute  a "Swap  Early
Termination."

      Upon the  occurrence  of any Swap  Default  under the  Interest  Rate Swap
Agreement,  the  non-defaulting  party will have the right to designate an Early
Termination  Date.  With respect to  Termination  Events  (including  Additional
Termination  Events),  an Early Termination Date may be designated by one of the
parties (as specified in the Interest Rate Swap  Agreement)  and will occur only
after notice has been given of the  Termination  Event,  all as set forth in the
Interest Rate Swap Agreement.  The occurrence of an Early Termination Date under
the Interest Rate Swap Agreement will constitute a "Swap Early Termination."


                                     S-131


      Upon any Swap Early  Termination,  the Supplemental  Interest Trust or the
Swap Provider may be liable to make a termination payment (the "Swap Termination
Payment") to the other party (regardless, if applicable, of which of the parties
has caused the termination).  The Swap Termination  Payment will be based on the
value of the  Interest  Rate Swap  Agreement  computed  in  accordance  with the
procedures set forth in the Interest Rate Swap Agreement taking into account the
present  value of the  unpaid  amounts  that  would have been owed to and by the
Supplemental  Interest Trust and the Swap Provider under the remaining scheduled
term of the  Interest  Rate Swap  Agreement.  In the event  that the  Securities
Administrator is required to make a Swap Termination Payment (to the extent such
amount  has not been  paid by the  Securities  Administrator  from  any  upfront
payment  received  pursuant  to  any  related  replacement  interest  rate  swap
agreement that may be entered into by the Supplemental  Interest Trust Trustee),
that payment will be paid from the  Supplemental  Interest  Trust on the related
Distribution Date, and on any subsequent  Distribution Dates until paid in full,
generally prior to distributions to  Certificateholders,  in accordance with the
priorities set forth in this prospectus supplement,  other than in the case of a
Swap  Termination  Payment  triggered upon a Swap Provider  Trigger  Event.  The
trust's obligation to pay amounts in respect of any Swap Termination Payment due
to a Swap Provider  Trigger Event will be subordinated to  distributions  to the
holders of the of the Class A Certificates and Mezzanine Certificates.

      Upon a Swap  Early  Termination,  the  Trustee,  at the  direction  of the
Depositor,  will seek a  replacement  swap  provider to enter into a replacement
interest rate swap agreement or similar agreement.  To the extent the Securities
Administrator  receives a Swap Termination  Payment from the Swap Provider,  the
Securities Administrator on behalf of the Supplemental Interest Trust will apply
all or such portion of such Swap  Termination  Payment as may be required to the
payment  of amounts  due to a  replacement  swap  provider  under a  replacement
interest rate swap agreement or similar  agreement.  Furthermore,  to the extent
the Securities  Administrator is required to pay a Swap  Termination  Payment to
the Swap Provider,  the Securities  Administrator  on behalf of the Supplemental
Interest  Trust  will  apply all or a portion  of such  amount  received  from a
replacement  swap provider  upon entering into a replacement  interest rate swap
agreement or similar  agreement to the Swap Termination  Payment amount owing to
the Swap  Provider.  In the event that the Securities  Administrator  receives a
Swap Termination Payment from the Swap Provider and a replacement swap agreement
or similar  agreement  cannot be  obtained  within 30 days after  receipt by the
Securities  Administrator  of such  Swap  Termination  Payment,  then  the  Swap
Administrator  will  deposit  such Swap  Termination  Payment  into a  separate,
non-interest  bearing  account and will, on each subsequent  Distribution  Date,
withdraw  from the amount then  remaining on deposit in such reserve  account an
amount equal to the Net Swap  Payment,  if any, that would have been paid to the
Swap  Administrator by the original Swap Provider  calculated in accordance with
the terms of the original  Interest Rate Swap  Agreement,  and  distribute  such
amount in accordance with the terms of the Pooling and Servicing Agreement.

      A Swap Termination Payment that is triggered upon: (i) an Event of Default
under the Interest Rate Swap  Agreement  with respect to which the Swap Provider
is a Defaulting Party (as defined in the Interest Rate Swap  Agreement),  (ii) a
Termination  Event under the Interest Rate Swap  Agreement with respect to which
the Swap  Provider is the sole  Affected  Party (as defined in the Interest Rate
Swap Agreement) or (iii) an Additional Termination Event under the Interest Rate
Swap  Agreement  with  respect to which the Swap  Provider is the sole  Affected
Party, will be a "Swap Provider Trigger Event."

      If the Swap  Provider's  credit  ratings are  withdrawn  or fall below the
levels  specified in the Interest Rate Swap Agreement,  then,  unless (x) within
the specified time period, each rating agency has reconfirmed the rating of each
offered  certificate which was in effect immediately prior to such withdrawal or
downgrade,  and (y) certain other  conditions are met, the Swap Provider will be
required,  at its own expense,  either (1) to obtain a substitute  swap provider
which will assume the  obligations  of the Swap Provider under the Interest Rate
Swap Agreement and which meets


                                     S-132


the  rating  requirements  provided  therein,  or (2)  to  establish  any  other
arrangement  specified in the Interest Rate Swap Agreement that meets the rating
requirements provided therein (collectively, the "Downgrade Provisions").

      On  each  Distribution  Date,  to  the  extent  required,   following  the
distribution of the Net Monthly Excess Cashflow and withdrawals from the Reserve
Fund, as described in  "--Overcollateralization  Provisions" in this  prospectus
supplement,  the  Securities  Administrator  will  withdraw  any  amounts in the
Supplemental  Interest Trust and distribute  such amounts in the following order
of priority:

            FIRST,  to the Swap Provider,  any Net Swap Payment owed to the Swap
Provider  pursuant to the Interest  Rate Swap  Agreement  for such  Distribution
Date;

            SECOND, to the Swap Provider,  any Swap Termination  Payment owed to
the Swap  Provider  not due to a Swap  Provider  Trigger  Event  pursuant to the
Interest Rate Swap Agreement;

            THIRD,  concurrently,  to each  class of Class A  Certificates,  the
related Senior Interest  Distribution  Amount remaining  undistributed after the
distributions  of the Group IA  Interest  Remittance  Amount,  Group IB Interest
Remittance Amount and Group II Interest  Remittance  Amount, on a PRO RATA basis
based on such respective remaining Senior Interest Distribution Amounts;

            FOURTH, sequentially,  to the Class M-1, Class M-2, Class M-3, Class
M-4, Class M-5, Class M-6, Class M-7, Class M-8, Class M-9, Class M-10 and Class
M-11 Certificates,  in that order, the related Interest  Distribution Amount and
Interest Carry Forward Amount, to the extent remaining  undistributed  after the
distributions  of the Group IA  Interest  Remittance  Amount,  Group IB Interest
Remittance  Amount and Group II Interest  Remittance  Amount and the Net Monthly
Excess Cashflow;

            FIFTH,  concurrently,  to each  class of Class A  Certificates,  the
related Net WAC Rate Carryover  Amount,  to the extent  remaining  undistributed
after  distributions  of Net Monthly  Excess  Cashflow on deposit in the Reserve
Fund,  on a PRO RATA  basis  based  on such  respective  Net WAC Rate  Carryover
Amounts remaining;

            SIXTH,  sequentially,  to the Class M-1, Class M-2, Class M-3, Class
M-4, Class M-5, Class M-6, Class M-7, Class M-8, Class M-9, Class M-10 and Class
M-11 Certificates,  in that order, the related Net WAC Rate Carryover Amount, to
the extent  remaining  undistributed  after  distributions of Net Monthly Excess
Cashflow on deposit in the Reserve Fund;

            SEVENTH, to the holders of the class or classes of Certificates then
entitled  to  receive  distributions  in  respect  of  principal,  in an  amount
necessary to maintain or restore the Required Overcollateralization Amount after
taking  into  account   distributions   made  pursuant  to  clause  FIRST  under
"--Overcollateralization Provisions;"

            EIGHTH,  sequentially  to the Class M-1, Class M-2, Class M-3, Class
M-4, Class M-5, Class M-6, Class M-7, Class M-8, Class M-9, Class M-10 and Class
M-11  Certificates,  in that  order,  in each case up to the  related  Allocated
Realized Loss Amount related to such  Certificates  for such  Distribution  Date
remaining undistributed after distribution of the Net Monthly Excess Cashflow;

            NINTH, to the Swap Provider, an amount equal to any Swap Termination
Payment owed to the Swap Provider due to a Swap Provider  Trigger Event pursuant
to the Interest Rate Swap Agreement; and

            TENTH, to the Class CE Certificates, any remaining amounts.


                                     S-133


      In  the  event  that  the  Supplemental  Interest  Trust  receives  a Swap
Termination Payment, and a successor Swap Provider cannot be obtained, then such
Swap  Termination  Payment  will be  deposited  into a reserve  account  and the
Securities  Administrator,  on each  subsequent  Distribution  Date  (until  the
termination date of the original  Interest Rate Swap  Agreement),  will withdraw
the  amount  of any Net Swap  Payment  due to the  Supplemental  Interest  Trust
(calculated  in  accordance  with the terms of the original  Interest  Rate Swap
Agreement) and administer  such Net Swap Payment in accordance with the terms of
the pooling and servicing agreement.

      The  Interest  Rate Swap  Agreement  will be governed by and  construed in
accordance  with the laws of the State of New York. The  obligations of the Swap
Provider are limited to those  specifically  set forth in the Interest Rate Swap
Agreement, as applicable.

CALCULATION OF ONE-MONTH LIBOR

      With  respect to each  Interest  Accrual  Period  (other  than the initial
Interest  Accrual Period) and the Offered  Certificates,  on the second business
day  preceding  such  Interest  Accrual  Period,  (each such date,  an "Interest
Determination  Date"),  the Securities  Administrator  will determine  One-Month
LIBOR for such Interest  Accrual  Period.  With respect to the initial  Interest
Accrual Period, on the Closing Date, the Securities Administrator will determine
One-Month LIBOR for such Interest Accrual Period based on information  available
on the second  business day  preceding  the Closing Date (the related  "Interest
Determination Date").  "One-Month LIBOR" means, as of any Interest Determination
Date, the London interbank offered rate for one-month U.S. dollar deposits which
appears on Telerate Page 3750 (as defined herein) as of 11:00 a.m. (London time)
on such date. If such rate does not appear on Telerate  Page 3750,  the rate for
that day will be  determined  on the basis of the offered rates of the Reference
Banks (as defined herein) for one-month U.S. dollar  deposits,  as of 11:00 a.m.
(London time) on such Interest Determination Date. The Securities  Administrator
will  request the  principal  London  office of each of the  Reference  Banks to
provide a quotation of its rate. If on such Interest  Determination  Date two or
more Reference  Banks provide such offered  quotations,  One-Month LIBOR for the
related  Interest  Accrual Period shall be the  arithmetic  mean of such offered
quotations  (rounded  upwards if  necessary  to the  nearest  whole  multiple of
0.0625%). If on such Interest  Determination Date fewer than two Reference Banks
provide  such  offered  quotations,  One-Month  LIBOR for the  related  Interest
Accrual  Period shall be the higher of (x) One-Month  LIBOR as determined on the
previous  Interest  Determination  Date and (y) the  Reserve  Interest  Rate (as
defined herein).

      As used in this  section,  "business  day" means a day on which  banks are
open for  dealing  in  foreign  currency  and  exchange  in London and New York;
"Telerate  Page 3750" means the display page  currently so designated on the Dow
Jones  Telerate  Capital  Markets Report (or such other page as may replace that
page on that service for the purpose of displaying  comparable rates or prices);
"Reference  Banks" means leading banks selected by the Securities  Administrator
and  engaged  in  transactions  in  Eurodollar  deposits  in  the  international
Eurocurrency  market (i) with an established  place of business in London,  (ii)
which have been designated as such by the Securities Administrator and (iii) not
controlling,  controlled  by, or under common control with, the Depositor or the
Securities  Administrator,  and  "Reserve  Interest  Rate" shall be the rate per
annum  that  the  Securities  Administrator  determines  to be  either  (i)  the
arithmetic  mean (rounded  upwards if necessary to the nearest whole multiple of
0.0625%) of the one-month  U.S.  dollar  lending rates which New York City banks
selected by the Securities  Administrator  are quoting on the relevant  Interest
Determination  Date to the  principal  London  offices of  leading  banks in the
London interbank  market or (ii) in the event that the Securities  Administrator
can determine no such arithmetic  mean, the lowest one-month U.S. dollar lending
rate which New York City banks  selected  by the  Securities  Administrator  are
quoting on such Interest Determination Date to leading European banks.


                                     S-136


      The establishment of One-Month LIBOR on each Interest  Determination  Date
by the Securities Administrator and the Securities  Administrator's  calculation
of the rate of interest  applicable to the Offered  Certificates for the related
Interest  Accrual  Period shall (in the absence of manifest  error) be final and
binding.

PRINCIPAL DISTRIBUTIONS ON THE OFFERED CERTIFICATES

      On each  Distribution  Date,  the  Principal  Distribution  Amount will be
distributed  to the  holders  of  the  Offered  Certificates  then  entitled  to
principal distributions. In no event will the Principal Distribution Amount with
respect to any Distribution  Date be (i) less than zero or (ii) greater than the
then  outstanding   aggregate  Certificate  Principal  Balance  of  the  Offered
Certificates.

      (A) On each  Distribution  Date (i) prior to the Stepdown  Date or (ii) on
which a Trigger Event is in effect, distributions in respect of principal to the
extent  of the  Group  IA  Principal  Distribution  Amount  will  be made in the
following amounts and order of priority:

            FIRST,  to the  Supplemental  Interest Trust, an amount equal to the
Group IA  Allocation  Percentage  of (i) any Net Swap  Payment  owed to the Swap
Provider and (ii) any Swap Termination Payment owed to the Swap Provider not due
to a Swap  Provider  Trigger  Event to the  extent  not paid  from the  Interest
Remittance Amount on such Distribution Date;

            SECOND,  to the  holders of the Class A-1A  Certificates,  until the
Certificate Principal Balance of the Class A-1A Certificates has been reduced to
zero; and

            THIRD,   concurrently,   (i)  to  the  holders  of  the  Class  A-1B
Certificates and (ii) to the holders of the Class A-2 Certificates, after taking
into account the distribution of the Group IB Principal  Distribution Amount and
the Group II Principal  Distribution  Amount each as described  below,  on a pro
rata basis, based on the Certificate  Principal Balance of each such class until
the Certificate  Principal  Balance of each such class has been reduced to zero;
provided,  however that the pro rata  allocation  to the Class A-2  Certificates

      The  allocation  of  distributions  in respect of principal to the Class A
Certificates on each  Distribution Date (a) prior to the Stepdown Date or (b) on
which a Trigger Event has  occurred,  will have the effect of  accelerating  the
amortization  of the Class A  Certificates  while,  in the  absence of  Realized
Losses,  increasing the respective  percentage interest in the principal balance
of the Mortgage Loans  evidenced by the Mezzanine  Certificates.  Increasing the
respective  percentage interest in the trust fund of the Mezzanine  Certificates
relative  to that of the  Class A  Certificates  is  intended  to  preserve  the
availability of the subordination provided by the Mezzanine Certificates.


                                     S-141


      Notwithstanding  the priority of  distributions  described in this section
with  respect  to the  Class  A-2A,  Class  A-2B,  Class  A-2C  and  Class  A-2D
Certificates,  on any  Distribution  Date  which  occurs  after the  Certificate
Principal  Balances  of the  Mezzanine  Certificates  have been  reduced to zero
distributions  in respect of principal to the Class A-2A, Class A-2B, Class A-2C
and  Class  A-2D  Certificates  will be made on a pro rata  basis,  based on the
Certificate  Principal  Balance  of  each  such  class,  until  the  Certificate
Principal Balance of each such class has been reduced to zero.

CREDIT ENHANCEMENT

      The credit  enhancement  provided  for the  benefit of the  holders of the
Class A Certificates  consists of  subordination,  as described in this section,
the Interest Rate Swap  Agreement,  as described under "--The Interest Rate Swap
Agreement and the Interest Rate Swap  Provider"  and  overcollateralization,  as
described   under   "--Overcollateralization   Provisions"  in  this  prospectus
supplement.

      The  rights of the  holders  of the  Subordinate  Certificates  to receive
distributions will be subordinated,  to the extent described in this section, to
the rights of the holders of the Class A  Certificates.  This  subordination  is
intended  to enhance  the  likelihood  of regular  receipt by the holders of the
Class A Certificates of the full amount of their scheduled  monthly  payments of
interest  and  principal  and to  afford  holders  of the  Class A  Certificates
protection against Realized Losses.

      The  protection  afforded  to the holders of the Class A  Certificates  by
means of the subordination of the Subordinate  Certificates will be accomplished
by (i) the  preferential  right of the  holders of the Class A  Certificates  to
receive on any  Distribution  Date,  prior to  distribution  on the  Subordinate
Certificates,  distributions  in respect of interest and  principal,  subject to
available  funds and (ii) if necessary,  the right of the holders of the Class A
Certificates to receive future  distributions of amounts that would otherwise be
payable to the holders of the Subordinate Certificates.

      In addition,  (i) the rights of the holders of the Class M-1  Certificates
will be senior to the rights of holders of the Class M-2,  Class M-3, Class M-4,
Class M-5, Class M-6,  Class M-7,  Class M-8, Class M-9, Class M-10,  Class M-11
and  Class CE  Certificates,  (ii) the  rights of the  holders  of the Class M-2
Certificates will be senior to the rights of the holders of the Class M-3, Class
M-4, Class M-5,  Class M-6,  Class M-7, Class M-8, Class M-9, Class M-10,  Class
M-11 and Class CE Certificates, (iii) the rights of the holders of the Class M-3
Certificates will be senior to the rights of the holders of the Class M-4, Class
M-5, Class M-6,  Class M-7,  Class M-8,  Class M-9,  Class M-10,  Class M-11 and
Class  CE  Certificates,  (iv)  the  rights  of the  holders  of the  Class  M-4
Certificates will be senior to the rights of the holders of the Class M-5, Class
M-6,  Class M-7,  Class  M-8,  Class M-9,  Class  M-10,  Class M-11 and Class CE
Certificates,  (v) the rights of the holders of the Class M-5 Certificates  will
be senior to the rights of the holders of the Class M-6,  Class M-7,  Class M-8,
Class M-9, Class M-10, Class M-11 and Class CE Certificates,  (vi) the rights of
the  holders of the Class M-6  Certificates  will


                                     S-144


be senior to the rights of the holders of the Class M-7,  Class M-8,  Class M-9,
Class  M-10,  Class  M-11 and Class CE  Certificates,  (vii)  the  rights of the
holders  of the Class  M-7  Certificates  will be  senior  to the  rights of the
holders  of the Class  M-8,  Class  M-9,  Class  M-10,  Class  M-11 and Class CE
Certificates,  (viii)  the rights of the  holders of the Class M-8  Certificates
will be senior to the rights of the holders of the Class M-9, Class M-10,  Class
M-11 and Class CE Certificates,  (ix) the rights of the holders of the Class M-9
Certificates  will be senior to the  rights of the  holders  of the Class  M-10,
Class M-11 and Class CE Certificates, (x) the rights of the holders of the Class
M-10  Certificates will be senior to the rights of the holders of the Class M-11
Certificates and Class CE Certificates and (xi) the rights of the holders of the
Class M-11 Certificates will be senior to the rights of the holders of the Class
CE  Certificates.  This  subordination  is intended to enhance the likelihood of
regular receipt by the holders of more senior  certificates of  distributions in
respect of interest and principal and to afford these holders protection against
Realized Losses.

OVERCOLLATERALIZATION PROVISIONS

      The  weighted  average  Mortgage  Rate for the  Mortgage  Loans,  less the
Administration  Fee Rate,  the amount,  expressed as a per annum rate of any Net
Swap  Payments  payable to the Swap Provider and any Swap  Termination  Payments
payable  to the Swap  Provider  not due to a Swap  Provider  Trigger  Event,  is
expected to be higher than the weighted average of the Pass-Through Rates on the
Offered Certificates,  thus generating excess interest collections which, in the
absence of Realized Losses, will not be necessary to fund interest distributions
on the Offered Certificates. Additional excess interest will be generated by the
portion of the Mortgage Pool  represented by the  Overcollateralization  Amount.
The pooling and servicing  agreement  requires that, on each Distribution  Date,
the Net Monthly Excess Cashflow,  if any, be applied on the related Distribution
Date as an  accelerated  payment of principal on the class or classes of Offered
Certificates then entitled to receive distributions in respect of principal, but
only to the limited extent described in this section.

      With respect to any  Distribution  Date, any Net Monthly  Excess  Cashflow
(or,  in the  case of  clause  FIRST  below,  the Net  Monthly  Excess  Cashflow
exclusive  of any  Overcollateralization  Reduction  Amount)  shall  be  paid as
follows:

            FIRST, to the holders of the class or classes of  certificates  then
entitled to receive distributions in respect of principal, in an amount equal to
the  Overcollateralization  Increase Amount for such Distribution  Date, owed to
such holders in  accordance  with the  priorities  set forth under  "--Principal
Distributions on the Offered Certificates" above;

            SECOND,  sequentially,  to the holders of the Class M-1,  Class M-2,
Class M-3,  Class M-4,  Class M-5,  Class M-6,  Class M-7, Class M-8, Class M-9,
Class M-10 and Class M-11 Certificates, in that order, in an amount equal to the
Interest Carry Forward Amount allocable to each such class;

            THIRD,  sequentially  to the  holders of the Class  M-1,  Class M-2,
Class M-3,  Class M-4,  Class M-5,  Class M-6,  Class M-7, Class M-8, Class M-9,
Class M-10 and Class M-11 Certificates, in that order, in an amount equal to the
Allocated Realized Loss Amount allocable to each such class;

            FOURTH, concurrently to the holders of the Class A Certificates,  in
an amount equal to such certificates' allocated share of any Prepayment Interest
Shortfalls  on  the  related  Mortgage  Loans  to  the  extent  not  covered  by
Compensating  Interest  paid by the  Master  Servicer  or the  Servicer  and any
shortfalls  resulting from the application of the Relief Act or similar state or
local law or the bankruptcy code with respect to the related Mortgage Loans;

            FIFTH,  sequentially  to the  holders of the Class  M-1,  Class M-2,
Class M-3,  Class M-4,  Class M-5,  Class M-6,  Class M-7, Class M-8, Class M-9,
Class M-10 and Class M-11  Certificates,  in


                                     S-145


that order, in an amount equal to each such certificates' allocated share of any
Prepayment  Interest  Shortfalls on the Mortgage Loans to the extent not covered
by  Compensating  Interest  paid by the Master  Servicer or the Servicer and any
shortfalls  resulting from the application of the Relief Act or similar state or
local law or the bankruptcy code with respect to the Mortgage Loans;

            SIXTH,  to the reserve  fund (the  "Reserve  Fund")  established  in
accordance with the terms of the pooling and servicing agreement,  the amount by
which the Net WAC Rate  Carryover  Amounts,  if any, with respect to the Offered
Certificates  exceeds the amount in the Reserve Fund that was not distributed on
prior Distribution Dates;

            SEVENTH, to the Supplemental  Interest Trust, an amount equal to any
Swap  Termination  Payment  owed to the Swap  Provider,  due to a Swap  Provider
Trigger Event pursuant to the Interest Rate Swap Agreement;

            EIGHTH,  to the  holders  of the Class P  Certificates  and Class CE
Certificates  as  provided in the Pooling  and  Servicing  Agreement;  provided,
however, that the Certificate Principal Balance of the Class P Certificates will
not be reduced  until the  Distribution  Date  following  the  expiration of the
latest prepayment charge term with respect to the Mortgage Loans; and

            NINTH,  to the holders of the Residual  Certificates,  any remaining
amounts.

      On each Distribution  Date, after making the distributions  required under
"Interest Distributions on the Offered Certificates",  "Principal  Distributions
on the  Offered  Certificates"  and after the  distribution  of the Net  Monthly
Excess Cashflow as described above, the Securities  Administrator  will withdraw
from the Reserve Fund the amounts on deposit therein and distribute such amounts
to the Class A Certificates and the Mezzanine Certificates in respect of any Net
WAC Rate  Carryover  Amounts due to each such class in the following  manner and
order of priority:

      (A) concurrently, to each class of Class A Certificates, in respect of the
related Net WAC Rate Carryover Amount for such Distribution  Date, on a pro rata
basis, based on the entitlement of each such class; and

      (B)  sequentially,  to the holders of the Class M-1, Class M-2, Class M-3,
Class M-4, Class M-5, Class M-6, Class M-7, Class M-8, Class M-9, Class M-10 and
Class M-11  Certificates,  in that order, in respect of the related Net WAC Rate
Carryover Amount for each such class for such Distribution Date.

      As of the Closing Date,  the aggregate  principal  balance of the Mortgage
Loans as of the Cut-off  Date will exceed the sum of the  aggregate  Certificate
Principal  Balances of the Offered  Certificates and the Class P Certificates by
an amount  equal to  approximately  $23,248,126,  which is equal to the  initial
Certificate  Principal  Balance  of  the  Class  CE  Certificates.  This  amount
represents  approximately  2.10%  of  the  aggregate  principal  balance  of the
Mortgage  Loans  as of  the  Cut-off  Date,  which  is  the  initial  amount  of
overcollateralization  required to be provided  by the  Mortgage  Pool under the
pooling and servicing agreement.  Under the pooling and servicing agreement, the
Overcollateralization  Amount is  required  to be  maintained  at the  "Required
Overcollateralization Amount." In the event that Realized Losses are incurred on
the Mortgage Loans, such Realized Losses may result in an  overcollateralization
deficiency  since the Realized  Losses will reduce the principal  balance of the
Mortgage Loans without a  corresponding  reduction to the aggregate  Certificate
Principal   Balances   of  the  Offered   Certificates.   In  the  event  of  an
overcollateralization  deficiency,  the pooling and servicing agreement requires
the payment from Net Monthly Excess Cashflow and any Net Swap Payments  received
from the Swap Provider in respect of the Interest Rate Swap  Agreement,  subject
to available funds, of an amount equal to the overcollateralization  deficiency,
which shall constitute a principal  distribution on the Offered  Certificates in
reduction of the  Certificate  Principal  Balances of the Offered  Certificates.
These


                                     S-146


payments  have the  effect  of  accelerating  the  amortization  of the  Offered
Certificates  relative  to  the  amortization  of  the  Mortgage  Loans,  and of
increasing the Overcollateralization Amount.

      On and after the Stepdown Date and provided that a Trigger Event is not in
effect, the Required  Overcollateralization  Amount may be permitted to decrease
("step  down"),  to a level  equal to  approximately  4.20% of the then  current
aggregate  outstanding  principal  balance of the Mortgage  Loans (after  giving
effect to  principal  payments to be  distributed  on the  related  Distribution
Date),  subject to a floor equal to the product (i) 0.50% and (ii) the aggregate
principal  balance of the Mortgage  Loans as of the Cut-off  Date.  In the event
that the Required  Overcollateralization Amount is permitted to step down on any
Distribution  Date, the pooling and servicing  agreement provides that a portion
of the  principal  which would  otherwise be  distributed  to the holders of the
Offered  Certificates on the related  Distribution  Date shall be distributed to
the holders of the Class CE  Certificates  pursuant to the  priorities set forth
above.

      With  respect  to  each  Distribution   Date,  the   Overcollateralization
Reduction Amount,  after taking into account all other  distributions to be made
on the related  Distribution  Date,  shall be  distributed as Net Monthly Excess
Cashflow  pursuant to the  priorities  set forth  above.  This has the effect of
decelerating  the  amortization  of the  Offered  Certificates  relative  to the
amortization  of the Mortgage Loans,  and of reducing the  Overcollateralization
Amount.  However,  if on any Distribution Date a Trigger Event is in effect, the
Required  Overcollateralization Amount will not be permitted to step down on the
related Distribution Date.

ALLOCATION OF LOSSES; SUBORDINATION

      With respect to any  defaulted  Mortgage  Loan that is finally  liquidated
through  foreclosure sale or disposition of the related  Mortgaged  Property (if
acquired on behalf of the  certificateholders  by deed in lieu of foreclosure or
otherwise),  the amount of loss realized,  if any, will equal the portion of the
unpaid principal  balance  remaining,  if any, plus interest thereon through the
last day of the month in which the related Mortgage Loan was finally  liquidated
or  charged-off,  after  application  of all amounts  recovered  (net of amounts
reimbursable to the Servicer or the Master Servicer for P&I Advances,  servicing
advances and other related expenses, including attorneys' fees) towards interest
and principal  owing on the Mortgage  Loan.  The amount of loss realized and any
Bankruptcy  Losses are referred to in this  prospectus  supplement  as "Realized
Losses."  In the event  that  amounts  recovered  in  connection  with the final
liquidation  of a defaulted  Mortgage  Loan are  insufficient  to reimburse  the
Servicer or the Master Servicer for P&I Advances,  servicing advances and unpaid
servicing  fees,  these  amounts may be reimbursed to the Servicer or the Master
Servicer out of any funds in the  collection  account prior to any remittance to
the Securities  Administrator of funds for distribution on the certificates.  In
addition, to the extent the Servicer receives Subsequent Recoveries with respect
to any defaulted  Mortgage Loan, the amount of the Realized Loss with respect to
that defaulted  Mortgage Loan will be reduced to the extent such  recoveries are
applied to reduce the Certificate Principal Balance of any class of Certificates
on any Distribution Date.

      Any  Realized  Losses  on the  Mortgage  Loans  will be  allocated  on any
Distribution  Date:  FIRST,  to Net  Monthly  Excess  Cashflow  and to Net  Swap
Payments  received from the Swap Provider under the Interest Rate Swap Agreement
for that purpose, SECOND, to the Class CE Certificates, THIRD, to the Class M-11
Certificates  until  the  Certificate   Principal  Balance  of  the  Class  M-11
Certificates has been reduced to zero,  FOURTH,  to the Class M-10  Certificates
until the Certificate  Principal Balance of the Class M-10 Certificates has been
reduced to zero,  FIFTH,  to the Class M-9  Certificates  until the  Certificate
Principal Balance of the Class M-9 Certificates has been reduced to zero, SIXTH,
to the Class M-8  Certificates  until the Certificate  Principal  Balance of the
Class M-8  Certificates  has been  reduced  to zero,  SEVENTH,  to the Class M-7
Certificates   until  the  Certificate   Principal  Balance  of  the  Class  M-7
Certificates  has been reduced to zero,  EIGHTH,  to the Class M-6  Certificates
until the Certificate  Principal  Balance of the Class M-6 Certificates has been
reduced to


                                     S-147


zero,  NINTH,  to the Class M-5  Certificates  until the  Certificate  Principal
Balance of the Class M-5  Certificates  has been reduced to zero,  TENTH, to the
Class M-4 Certificates until the Certificate  Principal Balance of the Class M-4
Certificates has been reduced to zero,  ELEVENTH,  to the Class M-3 Certificates
until the Certificate  Principal  Balance of the Class M-3 Certificates has been
reduced to zero,  TWELFTH,  to the Class M-2 Certificates  until the Certificate
Principal  Balance of the Class M-2  Certificates  has been  reduced to zero and
THIRTEENTH,  to the  Class M-1  Certificates  until  the  Certificate  Principal
Balance of the Class M-1 Certificates has been reduced to zero.

      The pooling and  servicing  agreement  does not permit the  allocation  of
Realized Losses to the Class A Certificates  or Class P Certificates.  Investors
in the Class A Certificates  should note that although Realized Losses cannot be
allocated to the Class A  Certificates,  under certain loss scenarios there will
not be enough  principal  and interest on the Mortgage  Loans to pay the Class A
Certificates all interest and principal amounts to which they are then entitled.

      Except as described below, once Realized Losses have been allocated to the
Mezzanine  Certificates,  such amounts with respect to such certificates will no
longer  accrue  interest,  and such  amounts will not be  reinstated  thereafter
(except in the case of  Subsequent  Recoveries  as  described  below).  However,
Allocated  Realized  Loss  Amounts may be paid to the  holders of the  Mezzanine
Certificates  from Net Monthly Excess Cashflow and from amounts  received by the
Securities  Administrator  under the Interest Rate Swap Agreement,  according to
the priorities set forth under  "--Overcollateralization  Provisions" and "--The
Interest  Rate  Swap  Agreement  anD  the  Swap  Provider"  in  this  prospectus
supplement.

      Any allocation of a Realized Loss to a Mezzanine  Certificate will be made
by reducing the Certificate  Principal Balance of that Certificate by the amount
so allocated as of the  Distribution  Date in the month  following  the calendar
month in which the Realized Loss was incurred.  Notwithstanding  anything to the
contrary  described  in  this  prospectus  supplement,  in  no  event  will  the
Certificate  Principal Balance of any Mezzanine Certificate be reduced more than
once in respect of any particular  amount both (i) allocable to such certificate
in respect of Realized  Losses and (ii)  payable as  principal  to the holder of
such certificate from Net Monthly Excess Cashflow and from amounts on deposit in
the Supplemental Interest Trust.

      A "Bankruptcy Loss" is a Deficient  Valuation or a Debt Service Reduction.
With respect to any Mortgage  Loan, a "Deficient  Valuation" is a valuation by a
court of competent jurisdiction of the Mortgaged Property in an amount less than
the then  outstanding  indebtedness  under the Mortgage  Loan,  which  valuation
results from a proceeding  initiated under the United States  Bankruptcy Code. A
"Debt  Service  Reduction"  is any  reduction in the amount which a mortgagor is
obligated to pay on a monthly  basis with respect to a Mortgage Loan as a result
of any proceeding  initiated under the United States Bankruptcy Code, other than
a reduction attributable to a Deficient Valuation.

      In the event that the Servicer  receives any Subsequent  Recoveries,  such
Subsequent Recoveries will be distributed as part of the Available  Distribution
Amount in accordance  with the priorities  described  under  "Description of the
Certificates"  in  this  prospectus  supplement  and the  Certificate  Principal
Balance of each class of Subordinate  Certificates  that has been reduced by the
allocation of a Realized Loss to such certificate will be increased, in order of
seniority,  by the amount of such  Subsequent  Recoveries but only to the extent
that such  certificate  has not been  reimbursed for the amount of such Realized
Loss (or any portion  thereof)  allocated to such  certificate  from Net Monthly
Excess     Cashflow    as     described     under     "Description     of    the
Certificates--Overcollateralization  Provisions"  and from amounts on deposit in
the  Supplemental   Interest  Trust  as  described  under  "Description  of  the
Certificates--The  Interest Rate Swap  Agreement and the Swap  Provider" in this
prospectus supplement.  Holders of such certificates will not be entitled to any
payment in respect of current  interest on the amount of such  increases for any
Interest Accrual Period  preceding the Distribution  Date on which such increase
occurs.

GENERAL

      The originator of the Mortgage Loans is Option One Mortgage Corporation, a
California corporation.

      The information set forth in the following paragraphs has been provided by
Option One Mortgage Corporation, referred to in this section as Option One.

OPTION ONE MORTGAGE CORPORATION

      Option One, a California corporation headquartered in Irvine,  California,
is the originator of the Mortgage Loans (the "Originator").

      Option One was incorporated in 1992, commenced receiving  applications for
mortgage  loans under its  regular  lending  program in February  1993 and began
funding such mortgage loans indirectly in the same month. The principal business
of Option One is the origination,  sale and servicing of non-conforming mortgage
loans. Option One is a wholly-owned  subsidiary of Block Financial,  which is in
turn a wholly-owned  subsidiary of H&R Block, Inc. ("H&R Block").  Borrowers who
qualify under the Originator's  underwriting guidelines generally have equity in
their property and repayment  ability but may have a record of major  derogatory
credit items such as outstanding judgments or prior bankruptcies. The Originator
originates  mortgage  loans based on its  underwriting  guidelines  and does not
determine whether such mortgage loans would be acceptable for purchase by Fannie
Mae or Freddie Mac.

      The  following  table  details  the  Originator's   wholesale  and  retail
originations  for the years  ended  April 30,  2003,  2004 and 2005 and the nine

OPTION ONE MORTGAGE CORPORATION

      The information set forth in the following paragraphs has been provided by
Option One.

SERVICING BACKGROUND AND PORTFOLIO

      Option One began  servicing  mortgage loans in February  1993,  originally
operating as a wholly owned  subsidiary of Plaza Home Mortgage Corp. The company
was acquired by Fleet Financial Group and began full servicing operations in May
1995. Block Financial subsequently purchased Option One in June 1997.

      Option One services primarily sub-prime  first-lien  residential  mortgage
loans.  Over 70% of the mortgage loans serviced by Option One were originated by
Option  One and over 65% of the


                                     S-153


mortgage  loans  serviced  by Option  One are in  private  residential  mortgage
asset-backed securities.

      Option One has experienced  substantial growth in its servicing  portfolio
in the past few  years,  both as a  result  of its  growth  in  origination  and
third-party  servicing.  The following table  summarizes  Option One's servicing
portfolio by origin at April 30, 2003, 2004 and 2005 and at January 31, 2006:

BUSINESS STRATEGY AND ORGANIZATIONAL STRUCTURE

      Option  One's  business  strategy  includes   incremental  growth  of  its
servicing  portfolio  through  origination  volume,   leveraging  and  expanding
selective  third-party  servicing  strategic  partnerships  for both interim and
long-term sub-servicing.

      Option One has a scalable  technology  platform and expansion  capacity to
support its business strategy.  Option One's loan  administration  functions are
performed  in U.S.  servicing  sites in  Irvine,  California  and  Jacksonville,
Florida, as well as offshore outsource  provider's sites in Noida,  Gurgaon, and
Bangalore,  India and  Guadalajara,  Mexico.  The two U.S.  offices  operate  in
parallel,  handling  many of the same  processes  for loans  across  the  entire
portfolio.  The use of an offshore outsource provider has increased Option One's
ability to perform customer service, welcome calls, new loan audits, early stage
collections,  and other loan  administration  functions.  By allocating staff to
multiple  sites,  Option One has the  ability to extend  its  service  hours and
improve customer satisfaction.

      Option  One's  organizational  structure  is  aligned  to best  serve  its
customers,  maximize loan  performance  and minimize risk  exposure.  Management
continually  refines and improves its technology to enhance  automated  workflow
processes and boost productivity  throughout the operation.  Option One utilizes
the Fidelity  Mortgage  Servicing  Package (MSP) as its main  servicing  system,
along with a number of ancillary vendor and proprietary systems.  Option One has
also  developed its own data  warehouse and REO and loss  mitigation  management
system.

      In order to improve  servicing  efficiency and  effectiveness,  Option One
outsources  certain  servicing tasks to a variety of third-party  vendors.  Such
servicing  tasks may  include:  property tax  processing  and  tracking,  hazard
insurance tracking and related forced placed insurance  coverage tasks,  certain
field  services,  foreclosure,  bankruptcy  and loss  mitigation and real estate
owned related tasks, lien release services and customer service functions. Three
material  components  of Option  One's  outsourcing  model  include  redundancy,
oversight and audit. In some instances,  more than one outsource  vendor is used
to perform the same function on different  segments of the  servicing  portfolio
which  encourages  competitive  pricing and performance and provides  additional
back-up capabilities. Option One's outsource vendor agreements provide that each
vendor strictly comply with Option One's guidelines, policies and procedures and
that any


                                     S-154


significant or material  decisions are not made by the outsource  vendor but are
elevated to Option One  associates.  Option One  maintains  quality  control and
review  processes  to assure that the  outsource  vendors are  performing  their
functions in accordance  with investor  requirements  and are in compliance with
applicable  federal and state law.  Option One also retains the right to perform
audits of outsource vendor's operations at Option One's sole discretion.

      Option  One's  mortgage  loan  document  custodial   responsibilities  are
performed by an independent custodian, or if applicable, a trustee in accordance
with the related servicing agreement.

DEFAULT MANAGEMENT

      Option  One  defines  and  measures   delinquencies   in  accordance  with
applicable investor  guidelines and agreements.  The company employs a proactive
approach to  resolving  delinquencies  with an emphasis  on  expedient  timeline
management.  Option One  pursues a dual track loss  mitigation  and  foreclosure
policy.  Initial contact is based on the borrower's previous payment patterns in
tandem with the application of Freddie Mac's  EarlyIndicator (EI) scoring model,
which  seeks to  identify  those  accounts  posing a  greater  risk of  default.
Collectors work extensive  evening and weekend shifts to effectively  manage the
nationwide  portfolio and are trained to identify loss mitigation  opportunities
and  solicit  workout  opportunities  during  the  collection  process.  Workout
specialists  maintain  contact with borrowers while an account is in foreclosure
in an attempt to arrange an alternate resolution to the delinquency and mitigate
future losses.  Option One's borrower  assistance  department  offers  borrowers
alternatives,  all within specific investor guidelines,  to foreclosure that may
include   reinstatement,   repayment  and  forbearance   plans,   modifications,
short-sales, and deed in lieu of foreclosure. A loan will remain in the borrower
assistance  area until a resolution has been reached or until a foreclosure  has
been completed.  Option One's  proprietary  system,  DARES, is a real estate and
loss mitigation  web-based  database that provides the borrower  assistance team
with an automated  decision tree and gain/loss  analysis,  centralization of the
repayment   plan  process,   efficient   autodialer   utilization   by  outbound
solicitation,  and web-based  applications  designed to provide  customers  with
optimal contact avenues.  Through DARES, loss mitigation specialists complete an
on-line  rules-based  net present  value  analysis  form,  which  documents  the
presumed   loss   exposure  on  the   property  and  compares  it  to  different
alternatives.  DARES is also  used for  monitoring,  tracking,  maintaining  and
communicating  all REO department  needs. When properties become REO, Option One
obtains property valuations and analyzes each property individually to determine
what sales  decisions  will result in the highest net return while  limiting the
marketing time.  Option One's REO assets are marketed and listed with local real
estate agents and published on local multiple listing services.  Option One uses
the internet for additional listing exposure.

      The  following  tables set forth,  at or for the years ended  December 31,
2002,  2003,  2004 and 2005,  certain  information  relating to the  delinquency
experience  (including  imminent  foreclosures,  foreclosures  in  progress  and
bankruptcies)  of one- to  four-family  residential  mortgage  loans included in
Option One's entire servicing portfolio (which portfolio includes mortgage loans
originated  under  the  Option  One  Guidelines  and  mortgage  loans  that  are
subserviced  for  others) at the end of the  indicated  periods.  The  indicated
periods of delinquency are based on the number of days past due on a contractual
basis. No mortgage loan is considered delinquent for these purposes until it has
not been paid by the next scheduled due date for such mortgage loan.

- ----------
(1)   "Total  Portfolio"  on the  date  stated  above  is the  aggregate  of the
      principal  balances of the mortgage  loans  outstanding on the last day of
      the period.
(2)   "Net Losses" means "Gross Losses" minus  "Recoveries."  "Gross Losses" are
      actual  losses  incurred  on  liquidated  properties  for each  respective
      period.   Losses  are  calculated   after   repayment  of  all  principal,
      foreclosure  costs,  servicing  fees and  accrued  interest to the date of
      liquidation.   "Recoveries"  are  recoveries  from  liquidation  proceeds,
      deficiency judgments and MI proceeds.
(3)   "Net Losses" are computed on a  loan-by-loan  basis and are reported  with
      respect to the period in which the loan is liquidated. If additional costs
      are incurred or recoveries are received  after the end of the period,  the
      amounts are adjusted  with respect to the period in which the related loan
      was  liquidated.  Accordingly,  the Net Losses  reported  in the table may
      change in future  periods.  The  information  in this table  reflects loan
      liquidations  through December 2005 and claims,  refunds or the collection
      of MI proceeds related to such liquidations through February 14, 2006.

      It is unlikely that the delinquency  experience of the Mortgage Loans will
correspond to the delinquency  experience of Option One's mortgage portfolio set
forth  in the  foregoing  tables.  The  statistics  shown  above  represent  the
delinquency  experience for Option One's mortgage  servicing  portfolio only for
the periods  presented,  whereas the  aggregate  delinquency  experience  on the
Mortgage Loans will depend on the results obtained over the life of the Mortgage
Pool. In particular,  investors should note that newly originated mortgage loans
will not be added to the Mortgage  Pool,  and the Mortgage  Pool will  therefore
consist of a static  pool of Mortgage  Loans,  whereas  new  mortgage  loans are
continually  being  originated  and added to the pool for which such  statistics
above are compiled.  Accordingly,  the actual loss and  delinquency  percentages
with respect to the  Mortgage  Pool are likely to be  substantially  higher than
those indicated in the tables above. In addition, if the residential real estate
market should experience an overall decline in property values, the actual rates
of  delinquencies  and  foreclosures  could  be  higher  than  those  previously
experienced by Option One.  Furthermore,  adverse economic conditions may affect
the timely payment by mortgagors of scheduled payments of principal and interest
on such Mortgage Loans and,  accordingly,  the actual rates of delinquencies and
foreclosures with respect to the Mortgage Pool.

TRAINING, INTERNAL CONTROLS AND COMPLIANCE

      Option  One  has  a  training   program   established  for  its  servicing
associates,  offering a wide  range of core job  specific  and  non-job-specific
training  (corporate,   soft  skills,  and  mortgage   fundamentals).   Training
curriculums  are  tailored  for  both  new  and  seasoned  associates.  Seasoned
employees receive job-specific training annually.  The training program includes
new hire orientation, process improvement methodology,  computer-based training,
system usage techniques,  leadership development, and soft skills, all conducted
by dedicated  business unit trainers.  The training is structured to ensure that
new  representatives  are  sufficiently  knowledgeable of the subject matter and
applicable regulations.  Training can take the form of classroom instruction,  a
simulated work environment exercise, and side-by-side  monitoring and mentoring.
Option One also has ongoing  leadership  development,  mentoring  programs,  and
policy  and  procedure  manuals  citing  applicable  statutes  that  are  widely
available to employees.

      Option One has controls in place which are intended to protect the company
and its investors against risk of loss. An internal audit program is utilized to
evaluate the company's  internal controls and safeguard against risk of loss due
to  noncompliance  with regulatory,  investor,  company,  and prudent  servicing
practices. In addition to oversight from the audit


                                     S-157


function,  Option  One  also  has  dedicated  compliance  and  legal  teams  for
servicing-related  issues,  regulations,  and  laws.  A quality  assurance  team
performs call monitoring and helps to ensure Federal Debt  Collections  Practice
Act (FDCPA) and Real Estate  Settlement  Procedures  Act (RESPA)  compliance.  A
quality  control  team  benchmarks  and measures  adherence  to best  practices,
identifies risk areas in servicing  operations,  centralizes  communication  for
regulatory,  investor,  and industry  updates,  and ensures that  associates are
being properly  trained on topics related to best practices and servicing  risk.
Risk  management  policies  in place that assist in  ensuring  prompt,  accurate
reporting  to its  investor  base  include  automated  reporting  and  remitting
processes,  segregation of duties among  reporting,  remitting,  and reconciling
tasks, web portal access for investors to view and download securitization data,
online access to bank statements,  and an account  liquidation  database to more
closely track  historical  losses on the portfolio and assist in trend analysis.
Option One uses its own  proprietary  lock-box,  which  provides  increased cash
management  controls  resulting from direct  oversight over the payment  posting
process.   Option  One  maintains  separate  bank  accounts  for  each  investor
relationship in accordance with the related  servicing  agreement  requirements.
These  custodial  accounts are  maintained  with Mellon  Bank,  N.A. and are not
commingled.

      Option  One is not aware and has not  received  notice  that any  default,
early amortization or other  performance-triggered  event has occurred as to any
other securitization due to any servicing act or servicing failure to act. There
have been no previous  disclosures of material  noncompliance by Option One with
servicing criteria relating to any other portfolio serviced by Option One.

LEGAL PROCEEDINGS PENDING AGAINST OPTION ONE

      In July 2004,  Option One Mortgage  Corporation was named as defendant and
served  with a class  action  complaint  filed by Larry and Brandi  Freitag,  as
plaintiffs, in the Third Judicial Circuit Court in Madison County, Illinois. The
complaint alleges breach of contract,  or in the alternative  unjust enrichment,
and violation of the Illinois  Consumer Fraud and Deceptive  Business  Practices
Act.  Specifically,  the plaintiffs allege that Option One Mortgage  Corporation
improperly  retained an extra day of per diem interest on  residential  mortgage
loans by charging per diem interest up to and including the date of payoff.  The
class is defined as all  persons in the United  States who paid  interest  on or
after  the day of  payoff  and who did not  receive  a refund  from  Option  One
Mortgage Corporation of the interest charged on or after the day of payoff. This
action is one of several actions filed earlier against other lenders by the same
attorneys on a similar  basis in the same court.  In one such action,  the court
granted the defendant's  motion to dismiss the plaintiff's claims of defendant's
violation of the Illinois Consumer Fraud and Deceptive  Business  Practices Act.
Plaintiffs have agreed to settle their individual  claims;  plaintiffs'  counsel
has a motion pending to continue  prosecution  of the class action.  Plaintiffs'
counsel filed a motion to substitute Larry and Pamela Smith as plaintiffs, which
was  granted.   Option  One  Mortgage  Corporation  filed  a  motion  to  compel
arbitration.

      In April 2005,  Option One Mortgage  Corporation  was named as a defendant
and served  with a class  action  complaint  filed by Carol  Vines and  Virginia
Loucile  Henderson,  as plaintiffs,  in the United States District Court for the
Eastern District of Texas, Lufkin Division. The complaint alleges that the Texas
Constitution  prohibits  lenders from making variable rate home equity loans and
seeks  forfeiture  of all Texas  variable  rate home equity  loans made prior to
December 30, 2003 in which the monthly  payment amount changed when the interest
rate  changed.  Texas' state courts have  dismissed  two similar  suits filed by
plaintiffs'  counsel. On September 27, 2005,  plaintiff,  Henderson  voluntarily
dismissed  her  claim.   Pending   before  the  Court  is  Option  One  Mortgage
Corporation's motion to dismiss the remaining plaintiff or in the alternative to
compel  arbitration.  Plaintiff's  counsel  has  notified  Option  One  Mortgage
Corporation of its intent to dismiss her complaint.


                                     S-158


      In  September  2005,  Option  One  Mortgage  Corporation  was  named  as a
defendant and served with a class action complaint filed by Pamela Phillips,  as
plaintiff,  in the United  States  District  Court for the  Central  District of
California,  Southern  Division.  The complaint alleges that Option One Mortgage
Corporation's  affiliate H&R Block Mortgage  Corporation  willfully obtained the
plaintiffs consumer credit report without a "permissible  purpose" as defined in
the  federal  Fair  Credit  Reporting  Act  and  without  the  plaintiff  having
authorized  such  access  or  initiated  a  transaction.   Option  One  Mortgage
Corporation  is named as a defendant  under the theory  that H&R Block  Mortgage
Corporation is its alter-ego.  Plaintiff's counsel has voluntarily dismissed her
complaint, without prejudice, against Option One Mortgage Corporation.

      On January 31, 2006,  the Circuit  Court of Cook County,  Illinois  County
Department,  Chancery  Division,  certified a nationwide  class  action  against
Option One Mortgage Corporation on a complaint brought by Erin and Earl Austria,
in which the  Austria's  allege that Option One  impermissibly  assessed  them a
reconveyance  fee and  authorized  the  assessment  of a title  indemnity fee on
certain mortgage loans that have been  paid-in-full.  Option One intends to seek
an interlocutory appeal of the order of class certification.

      In  February  2006,  Option One  Mortgage  Corporation  became  aware of a
September 2005 default judgment against it in an adversary proceeding brought by
Jeffrey  R.  Pierson  in the  United  States  Bankruptcy  Court for the  Eastern
District  of  Pennsylvania.  The  adversary  complaint  alleged  that Option One
engaged  in  various  "predatory   practices,"   including  improperly  applying
payments,   forced  placing  insurance,   commencing  foreclosure,   and  credit
reporting.  Option One has filed a motion to set aside the $2.4 million  default
judgment for failure of proper  service and to dismiss the  adversary  complaint
for failure to serve within one-eighty days of Plaintiff's filing his complaint.

SERVICING AND OTHER COMPENSATION AND PAYMENT OF EXPENSES

      The Servicer will provide  customary  servicing  functions with respect to
the Mortgage Loans serviced by the Servicer. Among other things, the Servicer is
obligated  under some  circumstances  to make P&I  Advances  with respect to the
related Mortgage Loans. In managing the liquidation of defaulted Mortgage Loans,
the  Servicer  will  have sole  discretion  to take  such  action in  maximizing
recoveries to the  certificateholders  including,  without  limitation,  selling
defaulted  Mortgage  Loans and REO  properties  as  described in the Pooling and
Servicing Agreement.

      As additional servicing  compensation,  the Servicer is entitled to retain
all  servicing-related  fees,  including  assumption  fees,  modification  fees,
extension  fees,  non-sufficient  funds  fees,  late  payment  charges and other
ancillary  fees and charges in respect of the related  Mortgage  Loans (with the
exception of Prepayment Charges, which will be distributed to the holders of the
Class P Certificates),  to the extent  collected from mortgagors,  together with
any interest or other income earned on funds held in the collection  account and
any escrow account.  The Servicer is entitled to retain any Prepayment  Interest
Excess (as defined in the Pooling and Servicing  Agreement)  with respect to the
Mortgage Loans.

      The  Servicer is  obligated to pay  insurance  premiums and other  ongoing
expenses   associated   with  the  Mortgage   Loans  in   connection   with  its
responsibilities  under the Pooling and Servicing Agreement,  and is entitled to
reimbursement  for these  expenses as  provided  in the  Pooling  and  Servicing
Agreement.  See "Description of the Agreement-Material  Terms of the Pooling and
Servicing  Agreements and  Underlying  Servicing  Agreements-Retained  Interest,
Servicing   Compensation   and  Payment  of  Expenses"  in  the  prospectus  for
information regarding expenses payable by the Servicer.

PAYMENTS ON MORTGAGE LOANS; DEPOSITS TO COLLECTION ACCOUNT

      The  Servicer  will  establish  and  maintain or cause to be  maintained a
separate  trust  account  (the  "Collection  Account")  for the  benefit  of the
certificateholders.  The  Collection  Account  will be an  Eligible  Account (as
defined in the Pooling and Servicing Agreement). Upon receipt by the Servicer of
amounts in respect of the Mortgage Loans  (excluding  amounts  representing  the
related  Servicing Fees or other servicing  compensation,  reimbursement for P&I
Advances  and  servicing  advances and  insurance  proceeds to be applied to the
restoration or repair of a Mortgaged  Property or similar  items),  the Servicer
will deposit such amounts in the Collection Account. Amounts so deposited by the
Servicer  may be invested in  Permitted  Investments  maturing no later than one
Business  Day  prior to the date on which  the  amount  on  deposit  therein  is
required to be remitted to the Securities  Administrator.  All investment income
on funds in the Collection Account shall be for the benefit of the Servicer.

under the laws of the  United  States or of any state  thereof  and  subject  to
supervision  and  examination  by  federal  and/or  state  banking   authorities
(including the trustee in its commercial  banking  capacity),  provided that the
commercial  paper and/or long term unsecured debt obligations of such depository
institution or trust company are then rated one of the two highest long-term and
the highest  short-term  ratings of each such rating agency for such securities,
or such lower ratings as will not result in the downgrading or withdrawal of the
rating then assigned to the  certificates by any rating agency,  as evidenced in
writing;

      (v)  guaranteed  reinvestment  agreements  issued by any  bank,  insurance

each rating agency.

PREPAYMENT INTEREST SHORTFALLS AND COMPENSATING INTEREST

      When a  principal  prepayment  in full is made  on a  Mortgage  Loan,  the
mortgagor  is  charged  interest  only for the  period  from the Due Date of the
preceding  monthly  payment up to the date of the  prepayment,  instead of for a
full month. When a partial principal  prepayment is made on a Mortgage Loan, the
mortgagor is not charged  interest on the amount of the prepayment for the month
in  which  the  prepayment  is  made.  In  addition,   the  application  of  the
Servicemembers  Civil Relief Act (the "Relief  Act") and similar  state or local
laws to any Mortgage Loan could adversely affect, for an indeterminate period of
time,  the ability of the  Servicer to collect  full amounts of interest on such
Mortgage  Loans.  The Servicer is obligated to pay from its own funds only those
interest shortfalls  attributable to voluntary principal  prepayments in full by
the  mortgagors on the Mortgage  Loans  received  during the related  Prepayment
Period;  provided,  however  that the  obligation  of the  Servicer to remit the
amount of any  shortfall in interest  resulting  from a principal  prepayment in
full on a Mortgage  Loan shall be limited  to the  aggregate  Servicing  Fee (as
defined herein) payable to the Servicer for the related Due Period. The Servicer
will not remit any shortfalls in interest attributable to the application of the
Relief  Act  or any  similar  state  or  local  laws.  Any  interest  shortfalls
attributable  to voluntary  principal  prepayments in full required to be funded
but not funded by the Servicer  are required to be paid by the Master  Servicer,
but only to the extent that such amount does not exceed the master servicing fee
payable  to  the  Master   Servicer  for  the  applicable   Distribution   Date.
Accordingly,   the  effect  of  interest  shortfalls  resulting  from  principal
prepayments  in full  or in part on the  Mortgage  Loans  (each,  a  "Prepayment
Interest  Shortfall")  to the extent that they exceed any payments by the Master
Servicer or the Servicer  ("Compensating  Interest") or any shortfalls resulting
from the  application of the Relief Act or similar state or local laws,  will be
to reduce the  aggregate  amount of interest  collected  that is  available  for
distribution to certificateholders.  Any such shortfalls will be allocated among
the  certificates as provided under  "Description of the  Certificates--Interest
Distributions  on  the  Offered  Certificates"  and  "--   Overcollateralization
Provisions"  in this  prospectus  supplement.  See "Certain Legal Aspects of the
Mortgage Loans--Servicemembers Civil Relief Act" in the prospectus.


                                     S-161


P&I ADVANCES

      Subject  to the  limitations  set forth in the  following  paragraph,  the
Servicer  will be obligated to advance or cause to be advanced on or before each
Servicer  Remittance Date its own funds, or funds in the Collection Account that
are not included in the Available Distribution Amount for the Distribution Date.
The  amount  of the  related  advance  will be  equal  to the  aggregate  of all
scheduled  payments of principal  and interest,  net of the Servicing  Fee, that
were due during the related Due Period on the  related  Mortgage  Loans and that
were delinquent on the related  Determination  Date,  plus amounts  representing
assumed  payments  not  covered  by any  current  net  income  on the  Mortgaged
Properties  acquired by foreclosure  or deed in lieu of foreclosure  (net of the
Servicing Fees). These advances are referred to in this prospectus supplement as
"P&I Advances".

      P&I Advances are required to be made only to the extent they are deemed by
the Servicer to be recoverable from related late collections, insurance proceeds
or liquidation  proceeds on the related Mortgage Loan. The purpose of making the
P&I  Advances  is to  maintain  a regular  cash flow to the  certificateholders,
rather than to  guarantee or insure  against  losses.  The Servicer  will not be
required to make any P&I Advances  with respect to  reductions  in the amount of
the monthly payments on any Mortgage Loans due to bankruptcy  proceedings or the
application  of the Relief Act or similar state or local laws.  All P&I Advances
will  be  reimbursable  to  the  Servicer  or  the  Master  Servicer  from  late
collections,  insurance proceeds and liquidation proceeds from the Mortgage Loan
as to which the unreimbursed P&I Advance was made. In addition, any P&I Advances
previously  made in respect of any Mortgage  Loan that are deemed by Servicer or
the  Master  Servicer  to  be  nonrecoverable  from  related  late  collections,
insurance proceeds or liquidation  proceeds may be reimbursed to the Servicer or
the Master  Servicer  out of any funds in the  Collection  Account  prior to the
distributions on the  certificates.  In the event that the Servicer fails in its
obligation  to make any  required  P&I  Advance,  a successor  servicer  will be
obligated  to make  the P&I  Advance  on the  Distribution  Date for  which  the
Servicer was required to make such P&I  Advance,  to the extent  required in the
Pooling and Servicing Agreement.

      In the event that a Balloon Loan is not paid in full on its maturity date,
the Servicer will also be obligated to make advances with respect to the assumed
monthly  payments  that would have been due on such  Balloon Loan based upon the
original  amortization  schedule  for the  Balloon  Loan,  unless  the  Servicer
determines  that the  advance  would not be  recoverable.  In no event  will the
Servicer be obligated to advance the balloon payment due on any Balloon Loan.

      Upon an Event of Default by the Servicer  under the Pooling and  Servicing
Agreement,  the Master  Servicer may  terminate  the  Servicer  and  appoint,  a
successor  servicer.  Such  successor  servicer must meet the  requirements  for
successor servicers under the Pooling and Servicing Agreement (including receipt
of  confirmation  from each Rating Agency that the appointment of such successor
servicer  would not lead to a  qualification,  downgrade  or  withdrawal  of the
ratings then assigned to the Offered  Certificates  in accordance with the terms
and conditions of the Pooling and Servicing Agreement).

      The Pooling and  Servicing  Agreement  also provides that the Servicer may
enter into a facility  with any person which  provides that such person may fund
P&I Advances or servicing  advances,  although no such facility  shall reduce or
otherwise  affect the  obligations  of the Servicer to fund such P&I Advances or
servicing  advances.  Any  P&I  Advances  or  servicing  advances  funded  by an
advancing  person will be reimbursed to the advancing  person in the same manner
as  reimbursements  would be made to the  Servicer.  The Pooling  and  Servicing
Agreement also provides that the Servicer may pledge its servicing  rights under
the Pooling and Servicing Agreement to one or more lenders.


                                     S-162


MODIFICATIONS

      In  instances  in which a  Mortgage  Loan is in  default  or if default is
reasonably  foreseeable,  and if  determined  by the  Servicer to be in the best
interest  of  the   certificateholders,   the  Servicer  may  permit   servicing
modifications  of the Mortgage  Loan rather than  proceeding  with  foreclosure.
However,  the  Servicer's  ability to perform  servicing  modifications  will be
subject to some  limitations,  including but not limited to the  following.  Any
amounts added to the  principal  balance of the Mortgage  Loan,  or  capitalized
amounts added to the Mortgage Loan,  will be required to be fully amortized over
the  remaining   term,  or  the  extended   term,  of  the  Mortgage  Loan.  All
capitalizations  are  to  be  implemented  in  accordance  with  the  Servicer's
standards  and may be  implemented  only by the Servicer for that  purpose.  The
final  maturity of any  Mortgage  Loan will not be  extended  beyond the assumed
final  distribution  date. No servicing  modification with respect to a Mortgage
Loan will have the effect of reducing  the  mortgage  rate below one half of the
mortgage rate as in effect on the Cut off Date,  but not less than the servicing
fee rate. Further, the aggregate current principal balance of all Mortgage Loans
serviced by the servicer and subject to  modifications  can be no more than five
percent (5%) of the aggregate  principal  balance of the Mortgage Loans serviced
by the Servicer as of the Cut-off Date, but this limit may increase from time to
time with the consent of the Rating Agencies.

      Any  advances  made on any  Mortgage  Loan will be reduced to reflect  any
related  servicing  modifications  previously  made.  The mortgage  rate and net
mortgage  rate  as to any  Mortgage  Loan  will be  deemed  not  reduced  by any
servicing  modification,  so that the  calculation of the Interest  Distribution
Amount  (as  defined  in this  prospectus  supplement)  payable  on the  Offered
Certificates will not be affected by the servicing modification.

EVIDENCE AS TO COMPLIANCE

      The Pooling and  Servicing  Agreement  will  provide  that each year on or
before the date set forth in the Pooling and Servicing Agreement, beginning with
the first  year  after the year in which the  Cut-off  Date  occurs,  each party
responsible for the servicing function will provide to the Depositor, the Master
Servicer  and the  Trustee  a report on an  assessment  of  compliance  with the
minimum servicing criteria established in Item 1122(a) of Regulation AB (the "AB
Servicing  Criteria").  The AB  Servicing  Criteria  include  specific  criteria
relating  to  the  following  areas:  general  servicing  considerations,   cash
collection and  administration,  investor  remittances  and reporting,  and pool
asset  administration.  Such report will indicate that the AB Servicing Criteria
were used to test  compliance  on a  platform  level  basis and will set out any
material instances of noncompliance.

      The Pooling and Servicing  Agreement will also provide that the each party
responsible  for the  servicing  function  will deliver along with its report on
assessment  of  compliance,  an  attestation  report from a firm of  independent
public  accountants  on the  assessment  of  compliance  with  the AB  Servicing
Criteria.

      The Pooling and Servicing  Agreement will also provide for delivery to the
Master Servicer,  the Securities  Administrator and the Trustee, each year on or
before the date set forth in the pooling and servicing agreement,  of a separate
annual  statement of compliance  from each entity  responsible for the servicing
function to the effect that, to the best knowledge of the signing  officer,  the
Servicer  has  fulfilled  in all material  respects  its  obligations  under the
Pooling and Servicing  Agreement  throughout the preceding year or, if there has
been a material  failure in the  fulfillment  of any  obligation,  the statement
shall specify such failure and the nature and status thereof. This statement may
be provided as a single form making the required  statements as to more than one
pooling and servicing agreement.

      Copies of the annual  reports of  assessment  of  compliance,  attestation
reports, and statements of compliance may be obtained by securityholders without
charge upon written


                                     S-163


request to the Master  Servicer at the address of the Master  Servicer set forth
under "The Securities  Administrator,  the Master Servicer and the Custodian" in
this prospectus supplement.  These items will be filed with the Issuing Entity's
annual report on Form 10-K, to the extent required under Regulation AB.

MASTER SERVICING AND OTHER COMPENSATION AND PAYMENT OF EXPENSES

      The principal compensation to be paid to the Master Servicer in respect of
its master servicing  activities for the certificates will be a master servicing
fee equal to one-twelfth  of the product of 0.0040%  multiplied by the Scheduled
Principal  Balance  of the  Mortgage  Loans as of the Due Date in the  preceding
calendar month. In addition, the Master Servicer will be entitled to interest or
other income earned on funds held in the Distribution Account.

      In the event that the Servicer  fails to pay the amount of any  Prepayment
Interest  Shortfall  required to be paid on any  Distribution  Date,  the Master
Servicer shall pay such amount up to the master servicing  compensation  payable
to the Master Servicer on such Distribution Date.

THE DISTRIBUTION ACCOUNT

      The Securities  Administrator will establish an account (the "Distribution
Account")  into which will be deposited  amounts  remitted to it by the Servicer
for  distribution to  certificateholders  on a Distribution  Date and payment of
certain  fees and  expenses of the trust.  The  Distribution  Account will be an
Eligible Account (as defined in the Pooling and Servicing Agreement). Amounts on
deposit  therein may be  invested in  Permitted  Investments  (as defined  under
"Servicing  of the  Mortgage  Loans -- Payments on Mortgage  Loans;  Deposits to
Collection  Account" in this  prospectus  supplement)  maturing on or before the
Business  Day prior to the  related  Distribution  Date  unless  such  Permitted
Investments  are invested in  investments  managed or advised by the  Securities
Administrator or an affiliate thereof, in which case such Permitted  investments
may mature on the related Distribution Date.

TRANSFER OF MASTER SERVICING

      The Master Servicer may sell and assign its rights and delegate its duties
and  obligations  in its  entirety  as Master  Servicer  under the  Pooling  and
Servicing Agreement;  provided,  however,  that: (i) the purchaser or transferee
accept in writing such  assignment and delegation and assume


                                     S-165


the obligations of the Master Servicer under the Pooling and Servicing Agreement
(a)  shall  have a net  worth of not less  than  $25,000,000  (unless  otherwise
approved by each Rating  Agency  pursuant  to clause (ii)  below);  (b) shall be
reasonably  satisfactory to the Trustee (as evidenced in a writing signed by the
Trustee); and (c) shall execute and deliver to the Trustee an agreement, in form
and  substance  reasonably  satisfactory  to  the  Trustee,  which  contains  an
assumption by such Person of the due and punctual  performance and observance of
each covenant and condition to be performed or observed by it as Master Servicer
under the Pooling and  Servicing  Agreement;  (ii) each Rating  Agency  shall be
given prior  written  notice of the  identity of the  proposed  successor to the
Master Servicer and each Rating  Agency's  rating of the  Certificates in effect
immediately  prior  to  such  assignment,   sale  and  delegation  will  not  be
downgraded,  qualified  or withdrawn  as a result of such  assignment,  sale and
delegation,  as  evidenced  by a letter to such effect  delivered  to the Master
Servicer and the Trustee;  and (iii) the Master  Servicer  assigning and selling
the master  servicing shall deliver to the Trustee an officer's  certificate and
an opinion of independent counsel, each stating that all conditions precedent to
such action under the Pooling and Servicing  Agreement  have been  completed and
such  action is  permitted  by and  complies  with the terms of the  Pooling and
Servicing Agreement. No such assignment or delegation shall affect any liability
of the Master  Servicer  arising out of acts or omissions prior to the effective
date thereof.

                                   THE TRUSTEE

      HSBC Bank USA, National  Association will be the Trustee under the Pooling
and Servicing  Agreement.  The  Depositor  and the Master  Servicer may maintain
other banking relationships in the ordinary course of business with the Trustee.
The Trustee's  corporate trust office is located at 452 Fifth Avenue,  New York,
New York 10018,  Attention:  Corporate Trust, ACE Securities  Corp., Home Equity
Loan  Trust,  Series  2006-OP1  or at such  other  address  as the  Trustee  may
designate from time to time.

      As of March 31, 2006,  HSBC Bank USA,  National  Association  is acting as
Trustee for approximately  400 asset-backed  securities  transactions  involving
similar pool assets to those found in this transaction.

      The Trustee,  prior to the occurrence of an Event of Default and after the
curing or waiver of all Events of Default which may have occurred, undertakes to
perform  such duties and only such duties as are  specifically  set forth in the
Pooling  and  Servicing  Agreement  as  duties  of the  Trustee,  including  the
followings:


                                     S-166


1.    Upon  receipt  of all  resolutions,  certificates,  statements,  opinions,
      reports,  documents,  orders or other  instruments  which are specifically
      required  to be  furnished  to the  Trustee  pursuant  to the  Pooling and
      Servicing  Agreement,  the Trustee  (or the  applicable  Custodian)  shall
      examine them to determine whether they are in the required form; provided,
      however,  that the Trustee  shall not be  responsible  for the accuracy or
      content  of  any  resolution,  certificate,  statement,  opinion,  report,
      document,  order  or  other  instrument  furnished  hereunder;   provided,
      further,  that the Trustee  shall not be  responsible  for the accuracy or
      verification of any calculation provided to it pursuant to the Pooling and
      Servicing Agreement.

2.    The Trustee shall  promptly  remit to the Servicer any  complaint,  claim,
      demand, notice or other document  (collectively,  the "Notices") delivered
      to the Trustee as a  consequence  of the  assignment  of any Mortgage Loan
      hereunder  and relating to the servicing of the Mortgage  Loans;  provided
      than any such  notice (i) is  delivered  to the  Trustee at its  Corporate
      Trust Office, (ii) contains  information  sufficient to permit the Trustee
      to make a  determination  that the real  property  to which such  document
      relates is a Mortgaged  Property (as defined in the Pooling and  Servicing
      Agreement).  The Trustee shall have no duty  hereunder with respect to any
      Notice it may receive or which may be alleged to have been delivered to or
      served upon it unless such Notice is  delivered to it or served upon it at
      its  Corporate  Trust  Office and such  Notice  contains  the  information
      required pursuant to clause (ii) of the preceding sentence.

3.    Except for those  actions  that the  Trustee is required to take under the
      Pooling and Servicing Agreement, the Trustee shall not have any obligation
      or  liability  to take any action or to refrain  from taking any action in
      the absence of written  direction as provided in the Pooling and Servicing
      Agreement.

      If an Event of Default has occurred and has not been cured or waived,  the
Trustee shall exercise such of the rights and powers vested in it by the Pooling
and  Servicing  Agreement,  using  the same  degree  of care and  skill in their
exercise,  as a prudent  person would exercise  under the  circumstances  in the
conduct of his own affairs.

      Without  limiting the generality of the foregoing,  if an Event of Default
shall occur,  the Trustee shall,  at the direction of at least 51% of the Voting
Rights, by notice in writing to the Master Servicer and to the Depositor, with a
copy to each Rating Agency,  terminate all of the rights and  obligations of the
Master  Servicer  in its  capacity  as Master  Servicer  under the  Pooling  and
Servicing Agreement,  to the extent permitted by law, and in and to the Mortgage
Loans and the proceeds  thereof.  On or after the receipt by the Master Servicer
of such written  notice,  all  authority  and power of the Master  Servicer with
respect to the  Certificates  (other than as a holder of any Certificate) or the
Mortgage Loans or otherwise  including,  without  limitation,  the  compensation
payable to the Master Servicer under the Pooling and Servicing Agreement,  shall
pass to and be vested in the Trustee, and, without limitation, the Trustee shall
be authorized and empowered,  as attorney-in-fact  or otherwise,  to execute and
deliver,  on behalf of and at the  expense of the Master  Servicer,  any and all
documents and other instruments and to do or accomplish all other acts or things
necessary or appropriate  to effect the purposes of such notice of  termination,
whether to complete the transfer and  endorsement  or assignment of the Mortgage
Loans and related documents,  or otherwise.  Notwithstanding the foregoing,  The
Trustee may, if is shall be  unwilling to so to act, or shall,  if it is legally
unable  to act,  appoint,  or  petition  a court of  competent  jurisdiction  to
appoint, a successor master servicer in accordance with the terms of the Pooling
and Servicing Agreement.

      To the extent that the costs and  expenses  of the Trustee  related to the
termination  of the Master  Servicer,  appointment  of a  successor  servicer or
master  servicer or the transfer and  assumption of the master  servicing by the
Trustee (including, without limitation, (i) all legal costs and expenses and all
due diligence costs and expenses  associated with an evaluation of the potential
termination  of the Master  Servicer as a result of an Event of Default and (ii)
all costs and


                                     S-167


expenses  associated  with the complete  transfer of the servicing or the master
servicing,  as applicable,  including all servicing files and all servicing data
and the completion,  correction or manipulation of such servicing data as may be
required by the successor  servicer or master  servicer to correct any errors or
insufficiencies  in the  servicing  data or  otherwise  to enable the  successor
master  servicer  to service or master  service the  related  Mortgage  Loans in
accordance  with the Pooling and Servicing  Agreement)  are not fully and timely
reimbursed by the terminated  master servicer,  the Trustee shall be entitled to
reimbursement of such costs and expenses from the Distribution Account.

      FOR  FURTHER  DISCUSSION  OF  THE  DUTIES  OF  THE  TRUSTEE,   PLEASE  SEE
"DESCRIPTION  OF THE  AGREEMENTS--MATERIAL  TERMS OF THE POOLING  AND  SERVICING
AGREEMENTS AND UNDERLYING  SERVICING  AGREEMENTS--DUTIES  OF THE TRUSTEE" IN THE
PROSPECTUS.

      The Master  Servicer  will pay the Trustee the trustee's fee in respect of
its  obligations  under the Pooling  and  Servicing  Agreement.  The Pooling and
Servicing  Agreement  will provide that the Trustee and any  director,  officer,
employee or agent of the Trustee  will be  indemnified  by the trust and will be
held harmless against any loss,  liability,  expense or cost including,  without
limitation,   attorneys   fees  and  expenses   (not   including   expenses  and
disbursements  incurred  or made by the  Trustee in the  ordinary  course of the
Trustee's  performance  in  accordance  with the  provisions  of the Pooling and
Servicing  Agreement)  incurred by the Trustee in connection with any pending or
threatened  legal action or arising out of or in connection  with the acceptance
or  administration of its obligations and duties under the Pooling and Servicing
Agreement,  the  Certificates or the Custodial  Agreement,  other than any loss,
liability or expense (i) resulting from a breach of the  obligations  and duties
of the Servicer under the Pooling and Servicing Agreement (for which the Trustee
receives  indemnity  from the  Servicer)  or (ii)  incurred by reason of willful
misfeasance,  bad faith or negligence in the performance of the Trustee's duties
under the Pooling and Servicing  Agreement,  the  Certificates  or the Custodial
Agreement or by reason of reckless disregard,  of the Trustee's  obligations and
duties  under the Pooling  and  Servicing  Agreement,  the  Certificates  or the
Custodial Agreement.

      The Trustee may resign at any time, in which event the  Depositor  will be
obligated  to appoint a successor  trustee.  The  Depositor  may also remove the
Trustee if the Trustee  ceases to be eligible to continue  under the Pooling and
Servicing Agreement or if the trustee becomes insolvent.  Upon becoming aware of
the  circumstances,  the  Depositor  will be  obligated  to appoint a  successor
trustee.  The  Trustee  may also be  removed  at any time by the  holders of the
certificates  evidencing  not less a majority of the voting  rights in the trust
fund. Any  resignation or removal of the Trustee and  appointment of a successor
trustee will not become  effective  until  acceptance of the  appointment by the
successor  trustee.  If the Trustee resigns or is removed by the Depositor,  the
expenses  associated  with the  change of  trustees  will be paid by the  former
trustee and reimbursed from the Distribution  Account. If the Trustee is removed
by holders of  certificates,  such holders shall be  responsible  for paying any
compensation payable to a successor trustee, in excess of the amount paid to the
predecessor trustee.

                             THE CREDIT RISK MANAGER

      Clayton  Fixed Income  Services  Inc.  (formerly  known as The  Murrayhill
Company),  as credit risk manager for the trust (the "Credit Risk Manager") will
monitor  the  performance  of the  Servicer,  and  make  recommendations  to the
Servicer  and/or Master  Servicer  regarding  certain  delinquent  and defaulted
Mortgage  Loans  and will  report to the  Depositor  on the  performance  of the
Mortgage  Loans,  pursuant to a Credit Risk  Management  Agreement to be entered
into by the Credit Risk Manager and the Servicer  and/or  Master  Servicer on or
prior to the Closing Date.  The Credit Risk Manager will rely upon mortgage loan
data that is provided to it by the Servicer and/or Master Servicer in performing
its advisory and monitoring functions.  The Credit Risk Manager will be entitled
to receive a "Credit Risk Manager's  Fee" until the  termination of the trust or
until its


                                     S-168


removal by a vote of at least 66 2/3% of the  Certificateholders.  Such fee will
be paid by the trust and will be equal to  one-twelfth of the product of 0.0130%
multiplied  by the then  current  aggregate  principal  balance of the  Mortgage
Loans.

                         POOLING AND SERVICING AGREEMENT

GENERAL

      The certificates will be issued under the Pooling and Servicing Agreement,
a form of which is filed as an exhibit to the registration  statement. A Current
Report on Form 8-K relating to the certificates containing a copy of the Pooling
and  Servicing  Agreement as executed  will be filed by the  Depositor  with the
Securities and Exchange Commission ("SEC") following the initial issuance of the
certificates.  The trust fund created under the Pooling and Servicing  Agreement
will  consist of (i) all of the  Depositor's  right,  title and  interest in the
Mortgage  Loans,  the  related  mortgage  notes,  mortgages  and  other  related
documents;  (ii) all payments on or collections in respect of the Mortgage Loans
due after the Cut-off Date,  together  with any proceeds of the Mortgage  Loans;
(iii) any  Mortgaged  Properties  acquired  on behalf of  certificateholders  by
foreclosure  or by deed in lieu of  foreclosure,  and any  revenues  received on
these mortgaged  properties;  (iv) the rights of the Trustee under all insurance
policies  required to be maintained  under the Pooling and Servicing  Agreement;
(v) the rights of the Depositor under the Mortgage Loan Purchase Agreement; (vi)
the Reserve  Fund and any  amounts on deposit in the  Reserve  Fund from time to
time and any proceeds  thereof;  and (vii) the right to any Net Swap Payment and
any Swap  Termination  Payment made by the Swap Provider under the Interest Rate
Swap Agreement.  For the avoidance of doubt, the trust fund does not include the
Supplemental  Interest Trust.  Reference is made to the prospectus for important
information  in  addition  to  that  set  forth  in this  prospectus  supplement
regarding the trust fund,  the terms and conditions of the Pooling and Servicing
Agreement  and  the  Offered  Certificates.  The  Depositor  will  provide  to a
prospective or actual  certificate  holder without charge, on written request, a
copy, without exhibits, of the Pooling and Servicing Agreement.  Requests should
be addressed to 6525 Morrison Blvd., Suite 318, Charlotte, North Carolina 28211.

ASSIGNMENT OF THE MORTGAGE LOANS

      On the Closing Date,  the Depositor  will transfer to the trust all of its
right,  title and interest in and to each Mortgage  Loan,  the related  mortgage
note,  mortgage,  assignment of mortgage in  recordable  form in blank and other
related  documents  (collectively,  the  "Related  Documents"),   including  all
scheduled payments with respect to each such Mortgage Loan due after the Cut-off
Date.  The  Trustee,   concurrently   with  such  transfer,   will  deliver  the
certificates to the Depositor.  Each Mortgage Loan transferred to the trust will
be identified  on a schedule (the  "Mortgage  Loan  Schedule")  delivered to the
Trustee and the Servicer  pursuant to the Pooling and Servicing  Agreement.  The
Mortgage Loan Schedule will include information such as the principal balance of
each Mortgage  Loan as of the Cut-off  Date,  its Mortgage Rate as well as other
information with respect to each Mortgage Loan.

      The  Pooling and  Servicing  Agreement  will  require  that,  prior to the
closing date, the Depositor will deliver or cause to be delivered to the Trustee
(or the Custodian,  as the Trustee's  agent for such purpose) the mortgage notes
endorsed  in blank and the  Related  Documents.  In lieu of delivery of original
mortgages or mortgage  notes,  if such  original is not  available or lost,  the
Depositor may deliver or cause to be delivered true and correct copies  thereof,
or, with respect to a lost mortgage note, a lost note affidavit. The assignments
of  mortgage  are  generally  required  to be  recorded  by or on  behalf of the
Depositor in the appropriate  offices for real property  records,  except (i) in
states as to which an opinion of counsel is  delivered  to the effect  that such
recording is not required to protect the Trustee's interest in the Mortgage Loan
against the claim of any  subsequent  transferee or any successor to or creditor
of the  Depositor  or the Sponsor,  or (ii) with


                                     S-169


respect to any  Mortgage  Loan  electronically  registered  through the Mortgage
Electronic Registration Systems, Inc.

      On or prior to the  Closing  Date,  the  Trustee or the  Custodian  on its
behalf will review the Mortgage Loans and the Related Documents  pursuant to the
Custodial Agreement and, if any Mortgage Loan or Related Document is found to be
defective  in any  material  respect and such defect is not cured within 90 days
following  notification  thereof to the Sponsor by the Trustee or the  Servicer,
the Sponsor will be obligated  either to (i) substitute for such Mortgage Loan a
Qualified Substitute Mortgage Loan; however, such substitution is permitted only
within two years of the  Closing  Date and may not be made  unless an opinion of
counsel is provided to the effect that such substitution will not disqualify any
of the REMICs (as defined in the Pooling and Servicing  Agreement) as a REMIC or
result in a prohibited  transaction  tax under the Code;  or (ii)  purchase such
Mortgage  Loan  at a price  (the  "Purchase  Price")  equal  to the  outstanding
principal  balance of such  Mortgage  Loan as of the date of purchase,  plus all
accrued and unpaid interest  thereon,  computed at the Mortgage Rate through the
end of the calendar month in which the purchase is effected,  plus the amount of
any unpaid  Servicing Fees or unreimbursed  P&I Advances and servicing  advances
made by the Servicer  plus all  unreimbursed  costs and damages  incurred by the
trust and the Trustee in connection with any violation by any such Mortgage Loan
of any predatory or abusive  lending law. The Purchase Price will be required to
be remitted to the  Servicer for deposit in the  Collection  Account (as defined
herein)  for  remittance  to the  Securities  Administrator  prior  to the  next
succeeding Distribution Date after such obligation arises. The obligation of the
Sponsor to  repurchase  or  substitute  for a Deleted  Mortgage Loan (as defined
herein) is the sole  remedy  regarding  any  defects in the  Mortgage  Loans and
Related Documents available to the certificateholders.

      In connection  with the  substitution of a Qualified  Substitute  Mortgage
Loan,  the Sponsor  will be required to remit to the Servicer for deposit in the
Collection Account for remittance to the Securities  Administrator  prior to the
next succeeding  Distribution  Date after such obligation  arises an amount (the
"Substitution Shortfall Amount") equal to the excess of the principal balance of
the related Deleted  Mortgage Loan over the principal  balance of such Qualified
Substitute Mortgage Loan.

      A "Qualified  Substitute Mortgage Loan" is a mortgage loan substituted for
a Deleted Mortgage Loan which must, on the date of such  substitution,  (i) have
an outstanding  principal balance (or in the case of a substitution of more than
one Mortgage Loan for a Deleted Mortgage Loan, an aggregate  principal balance),
not in excess of the principal balance of the Deleted Mortgage Loan; (ii) have a
Mortgage Rate not less than the Mortgage  Rate of the Deleted  Mortgage Loan and
not more than 1% in excess of the Mortgage Rate of such Deleted  Mortgage  Loan;
(iii) if such mortgage loan is an adjustable-rate  mortgage loan, have a Maximum
Mortgage Rate and Minimum  Mortgage Rate not less than the  respective  rate for
the Deleted  Mortgage  Loan and have a Gross Margin equal to or greater than the
Deleted Mortgage Loan; (iv) have the same Due Date as the Deleted Mortgage Loan;
(v) have a  remaining  term to maturity  not more than one year  earlier and not
later than the remaining  term to maturity of the Deleted  Mortgage  Loan;  (vi)
comply with each  representation and warranty as to the Mortgage Loans set forth
in the Mortgage  Loan  Purchase  Agreement  (deemed to be made as of the date of
substitution);  (vii) be of the same or better  credit  quality as the  Mortgage
Loan being replaced; (viii) have the same lien priority on the related mortgaged
property as the Mortgage  Loan being  replaced and (ix)  satisfy  certain  other
conditions specified in the Pooling and Servicing Agreement.

      The Sponsor will make certain  representations  and  warranties  as to the
accuracy  in all  material  respects  of certain  information  furnished  to the
Trustee  with  respect to each  Mortgage  Loan.  In  addition,  the Sponsor will
represent and warrant,  as of the Closing Date, that, among other things: (i) at
the time of transfer to the Depositor,  the Sponsor has  transferred or assigned
all of its right,  title and  interest  in each  Mortgage  Loan and the  Related
Documents,  free of any lien;


                                     S-170


(ii) each Mortgage Loan complied,  at the time of  origination,  in all material
respects with applicable  state and federal laws including,  but not limited to,
predatory  lending  laws;  (iii)  the  Mortgage  Loans  are not  subject  to the
requirements  of the Home  Ownership  and Equity  Protection  Act of 1994 and no
Mortgage  Loan is  classified  and/or  defined as a "high  cost",  "covered"  or
"predatory"  loan under any other  federal,  state or local law or  ordinance or
regulation  including,  but not  limited  to, the States of  Georgia,  Arkansas,
Kentucky, New Jersey, New Mexico, Indiana or Illinois; and (iv) no proceeds from
any Mortgage Loan were used to purchase single premium credit insurance policies
as part of the origination of, or as a condition to closing, such Mortgage Loan.
Upon  discovery  of a  breach  of any such  representation  and  warranty  which
materially and adversely affects the interests of the  certificateholders in the
related Mortgage Loan and Related  Documents,  the Sponsor will have a period of
90 days after the  earlier  of  discovery  or  receipt of written  notice of the
breach  to  effect  a  cure;   provided,   however   that  any   breach  of  the
representations  and warranties  set forth in clauses (ii),  (iii) or (iv) above
(or certain  other  representations  and  warranties  made by the  Sponsor  with
respect  to any Group IA  Mortgage  Loan or Group IB  Mortgage  Loan),  shall be
deemed   to   materially   and   adversely   affect   the   interests   of   the
certificateholders  in the related  Group IA Mortgage  Loan or Group IB Mortgage
Loan, as applicable. If the breach cannot be cured within the 90-day period, the
Sponsor will be obligated to (i)  substitute  for such Deleted  Mortgage  Loan a
Qualified  Substitute  Mortgage Loan or (ii) purchase such Deleted Mortgage Loan
from the trust.  The same procedure and limitations that are set forth above for
the  substitution or purchase of Deleted Mortgage Loans as a result of deficient
documentation  relating  thereto will apply to the substitution or purchase of a
Deleted Mortgage Loan as a result of a breach of a representation or warranty in
the Mortgage Loan Purchase  Agreement that materially and adversely  affects the
interests of the  certificateholders.  The Depositor will file the Mortgage Loan
Purchase Agreement as an exhibit to the Pooling and Servicing Agreement with the
Securities and Exchange Commission in a Current Report on Form 8-K.

      Mortgage  Loans  required to be transferred to the Sponsor as described in
the preceding paragraphs are referred to as "Deleted Mortgage Loans."

EVENTS OF DEFAULT

      Upon the occurrence of events of default  described under  "Description of
the  Agreements-Material  Terms of the  Pooling  and  Servicing  Agreements  and
Underlying  Servicing  Agreements-Events  of Default  under the  Agreement"  and
"-Rights Upon Events of Default under the  Agreements"  in the  prospectus,  the
Servicer  may be  removed  as the  servicer  of the  related  Mortgage  Loans in
accordance  with the terms of the Pooling and  Servicing  Agreement.  As further
described  in,  and in  accordance  with the  provisions  of,  the  Pooling  and
Servicing  Agreement upon the removal of the Servicer after the occurrence of an
Event of Default, a successor to the Servicer (which may be the Master Servicer)
will become the  successor  to the  Servicer  under the  Pooling  and  Servicing
Agreement. See "Description of the Agreements-Material  Terms of the Pooling and
Servicing Agreements and Underlying Servicing Agreements-Events of Default under
the Agreement" and "-Rights Upon Events of Default under the  Agreements" in the
prospectus.

VOTING RIGHTS

      At all times, 98% of all voting rights will be allocated among the holders
of the  Class A  Certificates,  the  Mezzanine  Certificates  and the  Class  CE
Certificates  in  proportion  to  the  then  outstanding  Certificate  Principal
Balances  of their  respective  certificates,  1% of all voting  rights  will be
allocated to the holders of the Class P  Certificates  in proportion to the then
outstanding  Certificate Principal Balances of their respective certificates and
1% of all  voting  rights  will be  allocated  to the  holders  of the  Residual
Certificates.  The initial owner of the Residual  Certificates  is Deutsche Bank
Securities Inc.


                                     S-171


TERMINATION

      The circumstances  under which the obligations  created by the Pooling and
Servicing  Agreement will terminate in respect of the certificates are described
in "Description  of the  Securities-Termination"  in the prospectus.  The Master
Servicer  will have the right to purchase all remaining  Mortgage  Loans and any
properties  acquired in respect  thereof and thereby effect early  retirement of
the certificates on any Distribution  Date following the Due Period during which
the aggregate principal balance of the Mortgage Loans and properties acquired in
respect  thereof  remaining in the trust fund at the time of purchase is reduced
to less than or equal to 10% of the aggregate  principal balance of the Mortgage
Loans as of the Cut-off  Date.  In the event the Master  Servicer  exercises its
option,  the purchase price payable in connection  with the option will be equal
to par with  respect  to the  Mortgage  Loans and the fair  market  value of all
properties  acquired by the trust in respect of any Mortgage Loans, plus accrued
interest  for  each  Mortgage  Loan  at the  related  Mortgage  Rate  to but not
including  the  first  day of  the  month  in  which  the  repurchase  price  is
distributed,  together  with (to the extent not  covered by the  foregoing)  all
amounts due and owing to the Trustee,  the Servicer,  the Master  Servicer,  the
Securities  Administrator  and the Swap Provider as of the termination  date and
pursuant to the Pooling  and  Servicing  Agreement  and the  Interest  Rate Swap
Agreement.  In the event the Master Servicer  exercises this option, the portion
of the  purchase  price  allocable to the Offered  Certificates  will be, to the
extent  of  available  funds,  (i)  100%  of the  then  outstanding  Certificate
Principal Balance of the Offered Certificates, plus (ii) one month's interest on
the then outstanding  Certificate  Principal Balance of the Offered Certificates
at the then  applicable  Pass-Through  Rate for each such class,  plus (iii) any
previously  accrued  but unpaid  interest  thereon  to which the  holders of the
Offered Certificates are entitled,  together with the amount of any Net WAC Rate
Carryover  Amounts.  The holders of the Residual  Certificates  shall pledge any
amount received in a termination in excess of par to the holders of the Class CE
Certificates.  In no event will the trust  created by the Pooling and  Servicing
Agreement  continue  beyond  the  expiration  of 21 years  from the death of the
survivor  of the  persons  named in the Pooling  and  Servicing  Agreement.  See
"Description of the Securities-Termination" in the prospectus.

      The Securities  Administrator  shall give notice of any termination to the
Certificateholders,  upon which the  Certificateholders  shall  surrender  their
Certificates  to  the  Securities   Administrator   for  payment  of  the  final
distribution and cancellation.  Such notice shall be given by letter, mailed not
earlier  than the l5th day and not  later  than the 25th day of the  month  next
preceding  the  month of such  final  distribution,  and shall  specify  (i) the
Distribution Date upon which final payment of the Certificates will be made upon
presentation  and surrender of the  Certificates at the office of the Securities
Administrator therein designated,  (ii) the amount of any such final payment and
(iii) that the Record Date otherwise applicable to such Distribution Date is not
applicable,  payments  being made only upon  presentation  and  surrender of the
Certificates at the office of the Securities Administrator therein specified.

      In the event such notice is given in  connection  with the purchase of all
of the Mortgage Loans by the Master Servicer,  the Master Servicer shall deliver
to the  Securities  Administrator  for deposit in the  Distribution  Account not
later than the  Business Day prior to the  Distribution  Date on which the final
distribution on the Certificates an amount in immediately  available funds equal
to the  above-described  Termination Price. The Securities  Administrator  shall
remit to the Servicer,  the Master Servicer,  the Trustee and the Custodian from
such funds  deposited  in the  Distribution  Account (i) any  amounts  which the
Servicer would be permitted to withdraw and retain from the  Collection  Account
as if such funds had been  deposited  therein  (including  all unpaid  Servicing
Fees,  Master  Servicing  Fees and all  outstanding  P&I Advances and  Servicing
Advances)  and  (ii) any  other  amounts  otherwise  payable  by the  Securities
Administrator to the Master Servicer,  the Trustee, the Custodian,  the Servicer
and the Swap  Provider  from  amounts  on deposit  in the  Distribution  Account
pursuant to the terms of the Pooling and Servicing Agreement prior to making any
final  distributions.  Upon  certification  to the  Trustee  by  the  Securities
Administrator  of


                                     S-172


the making of such final deposit, the Trustee shall promptly release or cause to
be released to the Master Servicer the Mortgage Files for the remaining Mortgage
Loans,  and  Trustee  shall  execute  all  assignments,  endorsements  and other
instruments delivered to it and necessary to effectuate such transfer.

      Upon  presentation of the  Certificates by the  Certificateholders  on the
final Distribution Date, the Securities  Administrator  shall distribute to each
Certificateholder  so presenting and  surrendering  its  Certificates the amount
otherwise distributable on such Distribution Date in respect of the Certificates
so presented and surrendered. Any funds not distributed to any Holder or Holders
of Certificates  being retired on such  Distribution Date because of the failure
of such Holder or Holders to tender their  Certificates  shall, on such date, be
set aside and held in trust  and  credited  to the  account  of the  appropriate
non-tendering Holder or Holders. If any Certificates as to which notice has been
given shall not have been surrendered for  cancellation  within six months after
the time  specified in such notice,  the Securities  Administrator  shall mail a
second notice to the  remaining  non-tendering  Certificateholders  to surrender
their  Certificates for cancellation in order to receive the final  distribution
with  respect  thereto.  If within  one year  after the  second  notice all such
Certificates  shall not have been surrendered for  cancellation,  the Securities
Administrator  shall,  directly or through an agent,  mail a final notice to the
remaining  non-tendering   Certificateholders   concerning  surrender  of  their
Certificates.  The costs and expenses of  maintaining  the funds in trust and of
contacting such Certificateholders  shall be paid out of the assets remaining in
the  trust  funds.  If within  one (1) year  after  the  final  notice  any such
Certificates  shall not have been surrendered for  cancellation,  the Securities
Administrator  shall pay to the Depositor  all such  amounts,  and all rights of
non-tendering Certificateholders in or to such amounts shall thereupon cease. No
interest shall accrue or be payable to any  Certificateholder on any amount held
in trust by the Securities Administrator as a result of such Certificateholder's
failure to surrender its Certificate(s) on the final Distribution Date for final
payment thereof. Any such amounts held in trust by the Securities  Administrator
shall be held uninvested in an Eligible Account.

      In the event that the Master Servicer  purchases all the Mortgage Loans or
the final payment on or other  liquidation  of the last Mortgage Loan, the Trust
Fund  shall  be  terminated  in   accordance   with  the  following   additional
requirements:

      (i) The Securities Administrator shall specify the first day in the 90-day
liquidation  period in a  statement  attached  to each Trust  REMIC's  final Tax
Return pursuant to Treasury  regulation  Section  1.860F-1 and shall satisfy all
requirements of a qualified  liquidation  under Section 860F of the Code and any
regulations thereunder, as evidenced by an opinion of counsel obtained by and at
the expense of the Master Servicer;

      (ii) During such 90-day liquidation period and, at or prior to the time of
making of the final payment on the  Certificates,  the Trustee shall sell all of
the assets of REMIC I to the Master Servicer for cash; and

      (iii) At the time of the making of the final payment on the  Certificates,
the  Securities  Administrator  shall  distribute  or  credit,  or  cause  to be
distributed or credited, to the Holders of the Residual Certificates all cash on
hand in the Trust Fund (other than cash retained to meet claims),  and the Trust
Fund shall terminate at that time.

      At  the  expense  of the  Terminator  (or,  if the  Trust  Fund  is  being
terminated as a result of the Last Scheduled  Distribution  Date, at the expense
of the Trust Fund),  the Master  Servicer  shall prepare or cause to be prepared
the  documentation  required  in  connection  with  the  adoption  of a plan  of
liquidation of each Trust REMIC.


                                     S-173


      By their acceptance of  Certificates,  the Holders thereof hereby agree to
authorize the Securities  Administrator to specify the 90-day liquidation period
for each Trust REMIC,  which  authorization  shall be binding upon all successor
Certificateholders.

                         FEDERAL INCOME TAX CONSEQUENCES

      In the opinion of Thacher  Proffitt & Wood LLP,  counsel to the Depositor,
assuming compliance with the provisions of the Pooling and Servicing  Agreement,
for  federal  income  tax  purposes,  each of the REMICs  established  under the
Pooling and Servicing Agreement will qualify as a REMIC under the Code.

      For  federal  income  tax  purposes  (i) the  Residual  Certificates  will
represent the  "residual  interests" in each REMIC elected by the trust and (ii)
the  Offered  Certificates  (exclusive  of any  right  of  the  holder  of  such
certificates  to receive  payments  from the Reserve  Fund in respect of Net WAC
Rate Carryover Amounts or from the Supplemental Interest Trust or the obligation
to make payments to the Supplemental  Interest Trust),  the Class P Certificates
and the Class CE  Certificates  will  represent the "regular  interests" in, and
will be treated as debt  instruments of, a REMIC.  See "Material  Federal Income
Tax Considerations-REMICs" in the prospectus.

      For federal income tax purposes, the Class M-10 Certificates and the Class
M-11 Certificates  will, and the remaining classes of Offered  Certificates may,
be treated as having been issued with original  issue  discount.  The prepayment
assumption  that will be used in  determining  the rate of accrual  of  original
issue  discount,  market  discount and premium,  if any, for federal  income tax
purposes  will be based on the  assumption  that,  subsequent to the date of any
determination the adjustable-rate  Mortgage Loans will prepay at a rate equal to
100% PPC  (calculated  based on the  assumed  prepayment  rates set forth  under
"Yield  on  the   Certificates--Weighted   Average  Lives"  in  this  prospectus
supplement)  and the  fixed-rate  Mortgage  Loans will prepay at a rate equal to
100% PPC calculated based on the assumed prepayment rates set forth under "Yield
on the Certificates--Weighted  Average Lives" in this prospectus supplement). No
representation  is made that the  Mortgage  Loans will prepay at that rate or at
any other rate.  See "Material  Federal  Income Tax  Consideration-General"  and
"-REMICs-Taxation of Owners of Regular Securities" in the prospectus.

      The  holders of the  Offered  Certificates  will be required to include in
income  interest on their  certificates in accordance with the accrual method of
accounting.

      The  Internal  Revenue  Service  (the  "IRS")  has issued  original  issue
discount  regulations (the "OID Regulations") under sections 1271 to 1275 of the
Code that address the treatment of debt  instruments  issued with original issue
discount,  Purchasers of the Offered  Certificates  should be aware that the OID
Regulations do not  adequately  address  certain issues  relevant to, or are not
applicable  to,  prepayable  securities  such as the  Offered  Certificates.  In
addition,  there is considerable  uncertainty  concerning the application of the
OID Regulations to REMIC Regular Certificates that provide for payments based on
an adjustable rate such as the Offered Certificates.  Because of the uncertainty
concerning  the   application  of  Section   1272(a)(6)  of  the  Code  to  such
certificates  and  because  the rules of the OID  Regulations  relating  to debt
instruments  having  an  adjustable  rate  of  interest  are  limited  in  their
application in ways that could preclude their  application to such  certificates
even in the absence of Section 1272(a)(6) of the Code, the IRS could assert that
the  Offered  Certificates  should be  treated  as issued  with  original  issue
discount  or should be  governed  by the rules  applicable  to debt  instruments
having  contingent  payments  or by some  other  method  not yet  set  forth  in
regulations.  Prospective  purchasers of the Offered Certificates are advised to
consult their tax advisors concerning the tax treatment of such certificates.


                                     S-174


      In certain  circumstances the OID Regulations  permit the holder of a debt
instrument to recognize original issue discount under a method that differs from
that  used  by  the  issuing  entity.  Accordingly,  the  holder  of an  Offered
Certificate  may be able to  select  a method  for  recognizing  original  issue
discount  that differs  from that used by the Trust in preparing  reports to the
certificateholders and the IRS.

      If the  method for  computing  original  issue  discount  described  above
results in a negative amount for any period with respect to a Certificateholder,
the amount of original issue discount allocable to that period would be zero and
the  Certificateholder  will be  permitted to offset that  negative  amount only
against  future  original  issue  discount,   if  any,   attributable  to  those
Certificates.

      Certain of the certificates may be treated for federal income tax purposes
as having been issued at a premium.  Whether any holder of a certificate will be
treated as holding such certificate with amortizable bond premium will depend on
such  certificateholders  purchase price and the  distributions  remaining to be
made  on  such   certificate   at  the   time   of  its   acquisition   by  such
certificateholder.  Holders of such  certificates  should  consult their own tax
advisors  regarding  the  possibility  of making an election  to  amortize  such
premium.  See "Material Federal Income Tax  Considerations-  REMICs--Taxation of
Owners of Regular Securities" in the Prospectus.

      Each  holder of an  Offered  Certificate  is  deemed  to own an  undivided
beneficial  ownership  interest  in a REMIC  regular  interest  and the right to
receive payments from either the Reserve Fund or the Supplemental Interest Trust
in  respect  of any Net WAC Rate  Carryover  Amount  or the  obligation  to make
payments to the Supplemental Interest Trust. The Reserve Fund, the Interest Rate
Swap Agreement and the Supplemental  Interest Trust are not assets of any REMIC.
The REMIC  regular  interest  corresponding  to an Offered  Certificate  will be
entitled  to receive  interest  and  principal  payments at the times and in the
amounts equal to those made on the certificate to which it  corresponds,  except
that (i) the maximum interest rate of that REMIC regular interest will equal the
Net WAC  Pass-Through  Rate  computed  for this  purpose  by  limiting  the Swap
Notional  Amount of the Interest Rate Swap Agreement to the aggregate  principal
balance of the  Mortgage  Loans and (ii) any Swap  Termination  Payment  will be
treated as being payable solely from Net Monthly Excess Cashflow. As a result of
the  foregoing,  the  amount  of  distributions  on the REMIC  regular  interest
corresponding  to an  Offered  Certificate  may  exceed  the  actual  amount  of
distributions on the Offered Certificate.

      The  treatment of amounts  received by a holder of an Offered  Certificate
under such holder's  right to receive any Net WAC Rate  Carryover  Amount,  will
depend  on the  portion,  if any,  of such  holder's  purchase  price  allocable
thereto. Under the REMIC Regulations, each holder of an Offered Certificate must
allocate  its purchase  price for the Offered  Certificate  among its  undivided
interest in the regular interest of the related REMIC and its undivided interest
in the right to receive  payments  from the  Reserve  Fund and the  Supplemental
Interest  Trust in respect of any Net WAC Rate  Carryover  Amount in  accordance
with the relative  fair market  values of each property  right.  The  Securities
Administrator  will,  as  required,  treat  payments  made to the holders of the
Offered  Certificates  with  respect to any Net WAC Rate  Carryover  Amount,  as
includible  in income based on the  regulations  relating to notional  principal
contracts (the "Notional Principal Contract  Regulations").  The OID Regulations
provide that the Trust's allocation of the issue price is binding on all holders
unless the holder explicitly  discloses on its tax return that its allocation is
different from the Trust's allocation.  For tax reporting purposes, the right to
receive  payments from the Reserve Fund and the  Supplemental  Interest Trust in
respect  of  Net  WAC  Rate  Carryover   Amount  with  respect  to  the  Offered
Certificates  may be treated as having more than a DE MINIMIS  value as provided
in  the  pooling  and  servicing   agreement.   Upon  request,   the  Securities
Administrator will make available information regarding such amounts as has been
provided to it. Under the REMIC  Regulations,  the Securities  Administrator  is
required  to  account  for the REMIC  regular  interest,  the  right to  receive
payments from the Reserve Fund and the Supplemental Interest Trust in respect of


                                     S-175


any Net WAC Rate Carryover Amount as discrete  property  rights.  Holders of the
Offered Certificates are advised to consult their own tax advisors regarding the
allocation of issue price, timing, character and source of income and deductions
resulting from the ownership of such  Certificates.  Treasury  regulations  have
been  promulgated  under  Section 1275 of the Code  generally  providing for the
integration of a "qualifying  debt instrument" with a hedge if the combined cash
flows of the  components  are  substantially  equivalent  to the cash flows on a
variable rate debt instrument.  However, such regulations  specifically disallow
integration  of debt  instruments  subject  to Section  1272(a)(6)  of the Code.
Therefore,  holders  of the  Offered  Certificates  will  be  unable  to use the
integration  method  provided for under such  regulations  with respect to those
Certificates. If the Securities Administrator's treatment of payments of any Net
WAC Rate  Carryover  Amount is respected,  ownership of the right to any Net WAC
Rate Carryover  Amount will entitle the owner to amortize the price paid for the
right to any Net WAC Rate Carryover Amount under the Notional Principal Contract
Regulations.

      Any  payments  made to a  beneficial  owner of an Offered  Certificate  in
excess of the amounts payable on the  corresponding  REMIC regular interest will
be  treated  as having  been  received  as a  payment  on a  notional  principal
contract.  To the extent the sum of such periodic  payments for any year exceeds
that year's  amortized  cost of any Net WAC Rate Carryover  Amount,  such excess
represents net income for that year.  Conversely,  to the extent that the amount
of that year's  amortized  cost exceeds the sum of the periodic  payments,  such
excess will  represent a net deduction  for that year. In addition,  any amounts
payable on such REMIC  regular  interest  in excess of the amount of payments on
the  Offered  Certificate  to which it relates  will be  treated as having  been
received by the  beneficial  owners of such  Certificates  and then paid by such
owners to the  Supplemental  Interest  Trust  pursuant to the Interest Rate Swap
Agreement, and such excess should be treated as a periodic payment on a notional
principal  contract that is made by the  beneficial  owner during the applicable
taxable  year and that is taken  into  account  in  determining  the  beneficial
owner's net income or net deduction  with respect to any Net WAC Rate  Carryover
Amount for such taxable year.  Although not clear, net income or a net deduction
with respect to any Net WAC Rate Carryover  Amount should be treated as ordinary
income or as an  ordinary  deduction.  Holders of the Offered  Certificates  are
advised to consult their own tax advisors regarding the tax characterization and
timing issues relating to a Swap Termination Payment.

      Because a beneficial  owner of any Net WAC Rate  Carryover  Amount will be
required to include in income the amount deemed to have been paid by such owner,
but may not be able to deduct that amount from income,  a beneficial owner of an
Offered  Certificate  may have income that  exceeds  cash  distributions  on the
Offered Certificate, in any period and over the term of the Offered Certificate.
As a result, the Offered  Certificates may not be a suitable  investment for any
taxpayer whose net deduction  with respect to any Net WAC Rate Carryover  Amount
would be subject to the limitations described above.

      Upon the sale of an Offered Certificate,  the amount of the sale allocated
to the selling  certificateholder's  right to receive  payments from the Reserve
Fund  and the  Supplemental  Interest  Trust  in  respect  of any  Net WAC  Rate
Carryover Amount would be considered a "termination  payment" under the Notional
Principal Contract Regulations allocable to the related Offered Certificate,  as
the case may be. A holder of an Offered  Certificate will have gain or loss from
such a  termination  of the right to receive  payments from the Reserve Fund and
the Supplemental  Interest Trust in respect of any Net WAC Rate Carryover Amount
equal to (i) any  termination  payment it received or is deemed to have received
minus (ii) the  unamortized  portion of any amount paid (or deemed  paid) by the
certificateholder  upon  entering into or acquiring its interest in the right to
receive  payments from the Reserve Fund and the  Supplemental  Interest Trust in
respect of any Net WAC Rate Carryover Amount.

      Gain or loss  realized  upon  the  termination  of the  right  to  receive
payments from the Reserve Fund and the Supplemental Interest Trust in respect of
any Net WAC Rate  Carryover


                                     S-176


Amount will generally be treated as capital gain or loss. Moreover,  in the case
of a bank or thrift  institution,  Code Section 582(c) would likely not apply to
treat such gain or loss as ordinary.

      It is  possible  that the right to receive  payments in respect of any Net
WAC Rate Carryover Amount could be treated as a partnership among the holders of
all of the Certificates,  in which case holders of such Certificates potentially
would be  subject to  different  timing of income  and  foreign  holders of such
Certificates  could be subject to  withholding in respect of any related Net WAC
Rate  Carryover  Amount.  Holders of the  Offered  Certificates  are  advised to
consult their own tax advisors regarding the allocation of issue price,  timing,
character and source of income and  deductions  resulting  from the ownership of
their Certificates.

      The REMIC regular interest  component of each Offered  Certificate will be
treated as assets described in Section  7701(a)(19)(C) of the Code, and as "real
estate assets" under Section  856(c)(5)(B) of the Code,  generally,  in the same
proportion that the assets of the Trust, exclusive of the assets not included in
any REMIC, would be so treated. In addition, the interest derived from the REMIC
regular  interest  component  of each  Offered  Certificate  will be interest on
obligations  secured by  interests  in real  property  for  purposes  of section
856(c)(3) of the Code, subject to the same limitation in the preceding sentence.
The Notional Principal  Contract component of each Regular  Certificate will not
qualify,  however, as an asset described in Section  7701(a)(19)(C) of the Code,
as a real estate asset under Section 856(c)(5)(B) of the Code or as a "qualified
mortgage" within the meaning of Section 860G(a)(3) of the Code. As a result, the
Offered  Certificates  generally may not be a suitable investment for a REMIC, a
real estate  investment  trust or an entity  intending to qualify  under Section
7701(a)(19)(C) of the Code.

      Because any Net WAC Rate Carryover Amount is treated as separate rights of
the Offered  Certificates  not payable by any REMIC  elected by the Trust,  such
rights will not be treated as qualifying assets for any  certificateholder  that
is a mutual savings bank,  domestic building and loan  association,  real estate
investment  trust, or REMIC. In addition,  any amounts received from the Reserve
Fund and the  Supplemental  Interest  Trust will not be  qualifying  real estate
income for real estate investment trusts or qualifying income for REMICs.

      For further  information  regarding  federal  income tax  consequences  of
investing  in  the  Offered  Certificates,  see  "Material  Federal  Income  Tax
Considerations--REMICs" in the prospectus.

                             METHOD OF DISTRIBUTION

      Subject to the terms and  conditions  set forth in the second  amended and
restated  underwriting  agreement,  dated as of June 24,  1999,  as amended  and
restated to and including,  January 25, 2006 and a terms  agreement  dated as of
May  17,  2006  (collectively,   the  "Underwriting  Agreement"),   between  the
Underwriter  and  the  Depositor,  the  Depositor  has  agreed  to  sell  to the
Underwriter,  and the Underwriter has agreed to purchase from the Depositor, the
Offered Certificates.

      Distribution of the Offered Certificates will be made from time to time in
negotiated  transactions  or otherwise at varying prices to be determined at the
time  of  sale.  Proceeds  to  the  Depositor  from  the  sale  of  the  Offered
Certificates, before deducting expenses payable by the Depositor, will be 99.80%
of  the  aggregate  initial   Certificate   Principal  Balance  of  the  Offered
Certificates.   In  connection  with  the  purchase  and  sale  of  the  Offered
Certificates,  the Underwriter may be deemed to have received  compensation from
the Depositor in the form of underwriting discounts.

      The Offered  Certificates are offered subject to receipt and acceptance by
the  Underwriter,  to prior  sale and to the  Underwriter's  right to reject any
order in whole or in part and to  withdraw,


                                     S-177


cancel or modify the offer without  notice.  It is expected that delivery of the
Offered Certificates will be made through the facilities of DTC, Clearstream and
the Euroclear System on or about the Closing Date. The Offered Certificates will
be offered in Europe and the United States of America.

      The Underwriting  Agreement provides that the Depositor will indemnify the
Underwriter  against  those  civil  liabilities  set  forth in the  Underwriting
Agreement,  including  liabilities under the Securities Act of 1933, as amended,
or will  contribute  to  payments  the  Underwriter  may be  required to make in
respect of these liabilities.

                                SECONDARY MARKET

      There is currently no secondary  market for the Offered  Certificates  and
there can be no assurance that a secondary  market for the Offered  Certificates
will develop or, if it does  develop,  that it will  continue.  The  Underwriter
intends  to  establish  a  market  in  the  Offered  Certificates  but it is not
obligated to do so. There can be no assurance  that any  additional  information
regarding the Offered  Certificates  will be available through any other source.
In  addition,  the  Depositor  is not aware of any source  through  which  price
information  about the  Offered  Certificates  will be  available  on an ongoing
basis. The limited nature of the information  regarding the Offered Certificates
may  adversely  affect the  liquidity  of the  Offered  Certificates,  even if a
secondary market for the Offered  Certificates  becomes  available.  The primary
source of information available to investors concerning the Offered Certificates
will be the  monthly  statements  discussed  herein  under  "Description  of the
Certificates-Reports to Certificateholders" which will include information as to
the outstanding  principal balance of the Offered Certificates and the status of
the applicable form of credit enhancement.

                                  LEGAL MATTERS

      Legal matters relating to the Offered Certificates will be passed upon for
the Depositor and the Underwriter by Thacher  Proffitt & Wood LLP, New York, New
York.

                                     RATINGS

      It is a condition  to the  issuance of the  certificates  that the Offered
Certificates  receive  at least the  following  ratings  from  Standard & Poor's
Ratings  Service,  a division of The  McGraw-Hill  Companies,  Inc.  ("S&P") and
Moody's Investors Service, Inc. ("Moody's"):

      The ratings  assigned to mortgage  pass-through  certificates  address the
likelihood of the receipt by  certificateholders  of all  distributions to which
the certificateholders are entitled. The rating process addresses structural and
legal  aspects  associated  with the  certificates,  including the nature of the
Mortgage Loans.  The ratings assigned to mortgage  pass-through  certificates do
not represent any assessment of the likelihood that principal  prepayments  will
be made by the  mortgagors or the degree to which such  prepayments  will differ
from that  originally  anticipated.  The ratings do not address the  possibility
that  certificateholders  might  suffer a lower  than  anticipated  yield due to
non-credit events. In addition,  the ratings on the Offered  Certificates do not
address the  likelihood  of receipt by the holders of such  certificates  of any
amounts in respect of Net WAC Rate  Carryover  Amounts from amounts  received or
advanced on the Mortgage Loans.

      A security rating is not a recommendation  to buy, sell or hold securities
and may be subject to revision or withdrawal at any time by the assigning rating
organization.  Each  security  rating should be evaluated  independently  of any
other security rating. In the event that the ratings  initially  assigned to the
Offered  Certificates  are  subsequently  lowered for any  reason,  no person or
entity  is  obligated  to  provide  any  additional  credit  support  or  credit
enhancement with respect to the Offered Certificates.

      The Depositor  has not  requested  that any rating agency rate the Offered
Certificates other than as stated above.  However,  there can be no assurance as
to whether any other rating agency will rate the Offered Certificates, or, if it
does, what rating would be assigned by any other rating agency.  A rating on the
Offered  Certificates by another rating agency, if assigned at all, may be lower
than the ratings assigned to the Offered Certificates as stated in this section.

      The  rating  agencies  have  stated  that it is their  standard  policy to
monitor  ratings  on  publicly  offered  securities  for which a rating has been
provided,  as to each rating agency rating each class of Offered Certificates in
accordance with the rating agencies' particular  surveillance  policies,  unless
the Issuing Entity requests a rating without surveillance.  A rating agency will
monitor the rating it issues on an ongoing basis and may update the rating after
conducting its regular review of the Issuing Entity's  creditworthiness or after
conducting  a review of the  status of the  rating  upon  becoming  aware of any
information  that might  reasonably be expected to result in a change of rating.
The Depositor has not requested that any rating agency not monitor their ratings
of the Offered Certificates, and the Depositor has not requested that any rating
agency  use any  monitoring  procedures  other than  their  standard  monitoring
procedures.

                                LEGAL PROCEEDINGS

      There are no material legal proceedings  pending against the Sponsor,  the
Depositor,  the Trustee, the Issuing Entity, the Master Servicer,  the Servicer,
the  Securities  Administrator,  the  Custodian,  or with  respect  to which the
property  of any of the  foregoing  transaction  parties  is  subject,  that are
material  to the  Certificateholders.  No legal  proceedings  against any of the
foregoing  transaction  parties  is known  to be  contemplated  by  governmental
authorities, that are material to the Certificateholders.

              AFFILIATIONS, RELATIONSHIPS AND RELATED TRANSACTIONS

      There are no  affiliations  between  the  Sponsor,  the  Depositor  or the
Issuing Entity and any of the Master Servicer,  the Servicer,  the Trustee,  the
Securities  Administrator,  the Swap  Provider

or Wells Fargo Bank, National Association,  in its capacity as Custodian.  There
are no  affiliations  among  the  Master  Servicer  or the  Servicer.  There are
currently no business relationships,  agreements, arrangements,  transactions or
understandings  between (a) the Sponsor, the Depositor or the Issuing Entity and
(b) the  Master  Servicer,  the  Securities  Administrator,  Wells  Fargo  Bank,
National  Association,  as a custodian,  the Servicer,  the Swap Provider or the
Trustee, or any of their respective  affiliates,  that were entered into outside
the normal course of business or that contain terms other than would be obtained
in an arm's  length  transaction  with an  unrelated  third  party  and that are
material to the investor's understanding of the Certificates,  or that relate to
the Certificates or the pooled assets. No such business relationship, agreement,
arrangement, transaction or understanding has existed during the past two years.

                                LEGAL INVESTMENT

      The Offered Certificates, other than the Class A-1A Certificates, will not
constitute  "mortgage related securities" for purposes of the Secondary Mortgage
Market Enhancement Act of 1984 ("SMMEA").  As of the date of their issuance, the
Class A-1A  Certificates  will  constitute  "mortgage  related  securities"  for
purposes of SMMEA and as such will be legal  investments  for  persons,  trusts,
corporations,  partnerships, associations, business trusts and business entities
(including depository institutions,  life insurance companies and pension funds)
created  pursuant to or existing  under the laws of the United  States or of any
state whose  authorized  investments are subject to state regulation to the same
extent that,  under  applicable law,  obligations  issued by or guaranteed as to
principal  and  interest by the United  States or any agency or  instrumentality
thereof constitute legal investments for such entities.  Under SMMEA, if a state
enacted  legislation  before  October 4, 1991  specifically  limiting  the legal
investment  authority of any of such entities with respect to "mortgage  related
securities",  the Class A-1A  Certificates will constitute legal investments for
entities  subject  to such  legislation  only to the  extent  provided  therein.
Certain states have enacted such legislation. Investors should consult their own
legal  advisors  in   determining   whether  and  to  what  extent  the  Offered
Certificates constitute legal investments for such investors.

      SMMEA also amended the legal investment  authority of federally  chartered
depository  institutions as follows:  federal savings and loan  associations and
federal  savings banks may invest in, sell or otherwise deal with the Class A-1A
Certificates,   without   limitation  as  to  the  percentage  of  their  assets
represented  thereby;  federal  credit  unions  may  invest  in the  Class  A-1A
Certificates,  and national banks may purchase the Class A-1A  Certificates  for
their own accounts  without regard to the  limitations  generally  applicable to
investment securities set forth in 12 U.S.C. 24 (Seventh);  in each case subject
to  such  regulations  as  the  applicable  federal  regulatory   authority  may
prescribe. See "Legal Investment" in the prospectus.

      Investors  should consult their own legal advisors in determining  whether
and to what extent the Offered  Certificates  constitute  legal  investments for
such investors.

      Except with respect to the  classification  of the Class A-1A Certificates
as "mortgage  related  securities" for purposes of SMMEA, the Depositor makes no
representations  as to the  proper  characterization  of any  class  of  Offered
Certificates  for legal  investment or other  purposes,  or as to the ability of
particular  investors  to  purchase  any  class of  Offered  Certificates  under
applicable  legal investment  restrictions.  These  uncertainties  may adversely
affect the  liquidity  of any class of Offered  Certificates.  Accordingly,  all
institutions  whose  investment  activities are subject to legal investment laws
and  regulations,  regulatory  capital  requirements  or  review  by  regulatory
authorities should consult with their legal advisors in determining  whether and
to what extent any class of Offered Certificates  constitutes a legal investment
or  is  subject  to  investment,  capital  or  other  restrictions.  See  "Legal
Investment" in the Prospectus.

                    CONSIDERATIONS FOR BENEFIT PLAN INVESTORS

      Section 406 of the Employee  Retirement  Income  Security Act of 1974,  as
amended  ("ERISA"),  prohibits "parties in interest" with respect to an employee
benefit plan subject to ERISA from  engaging in certain  transactions  involving
such  plan and its  assets  unless a  statutory,  regulatory  or  administrative
exemption  applies to the transaction.  Section 4975 of the Code imposes certain
excise taxes on prohibited  transactions  involving  "disqualified  persons" and
employee  benefit plans or other  arrangements  (including,  but not limited to,
individual  retirement accounts) described under that section (collectively with
employee  benefit  plans  subject  to  ERISA,  "Plans").  ERISA  authorizes  the
imposition of civil  penalties for prohibited  transactions  involving Plans not
covered under Section 4975 of the Code.  Any Plan  fiduciary  which  proposes to
cause a Plan to acquire  Offered  Certificates is encouraged to consult with its
counsel with respect to the potential  consequences  under ERISA and the Code of
the Plan's  acquisition and ownership of such Offered  Certificates.  See "ERISA
Considerations" in the prospectus.

      Certain employee benefit plans,  including  governmental plans and certain
church plans, are not subject to ERISA's  requirements.  Accordingly,  assets of
such plans may be invested in Offered  Certificates  without regard to the ERISA
considerations described herein and in the prospectus, subject to the provisions
of other applicable  federal and state law. Any such plan which is qualified and
exempt  from  taxation  under  Sections  401(a)  and  501(a)  of  the  Code  may
nonetheless be subject to the prohibited  transaction rules set forth in Section
503 of the Code.

      Except as noted above, investments by Plans are subject to ERISA's general
fiduciary  requirements,  including the  requirement of investment  prudence and
diversification  and  the  requirement  that a  Plan's  investments  be  made in
accordance  with the documents  governing the Plan. A fiduciary which decides to
invest the assets of a Plan in a class of Offered  Certificates should consider,
among other factors,  the extreme  sensitivity of the investments to the rate of
principal payments (including prepayments) on the mortgage loans.

      The U.S.  Department of Labor has issued an Exemption,  as described under
"ERISA  Considerations"  in the prospectus,  to the Underwriters.  The Exemption
generally exempts from the application of certain of the prohibited  transaction
provisions  of  Section  406 of ERISA,  and the  excise  taxes  imposed  on such
prohibited  transactions  by  Section  4975(a)  and (b) of the Code and  Section
502(i) of ERISA,  transactions  relating  to the  purchase,  sale and holding of
pass-through  certificates  rated at least  "BBB-" (or its  equivalent)  by S&P,
Fitch  Ratings  or  Moody's  at the time of  purchase  and  underwritten  by the
Underwriters  and the  servicing  and  operation  of asset pools  consisting  of
certain types of secured obligations,  such as mortgage loans, provided that the
conditions of the Exemption are  satisfied.  However,  the Exemption  contains a
number of conditions which must be met for the Exemption,  as amended,  to apply
(as described in the  prospectus),  including the requirement that any such Plan
must be an "accredited investor" as defined in Rule 501(a)(1) of Regulation D of
the  Securities  and Exchange  Commission  under the  Securities Act of 1933, as
amended. A fiduciary of a Plan contemplating  purchasing an Offered  Certificate
must make its own determination  that the conditions set forth in the Exemption,
as amended,  will be satisfied with respect to such certificates,  including the
requirement  that the rating on a particular  class of Certificates be "BBB-" or
higher at the time of purchase.

      For so long as the holder of an Offered Certificate also holds an interest
in the  Supplemental  Interest Trust, the holder will be deemed to have acquired
and be holding the  Offered  Certificate  without the right to receive  payments
from the  Supplemental  Interest  Trust  and,  separately,  the right to receive
payments from the  Supplemental  Interest Trust. The Exemption is not applicable
to the  acquisition,  holding and  transfer  of an interest in the  Supplemental
Interest  Trust.  In  addition,  while  the  Supplemental  Interest  Trust is in
existence,  it is possible that not all of the requirements for the Exemption to
apply to the acquisition,  holding and transfer of Offered  Certificates will be
satisfied.  However,  if the  Exemption  is not  available,  there  may be other


                                     S-181


exemptions that may apply. Accordingly,  no Plan or other person using assets of
a Plan  may  acquire  or hold an  Offered  Certificate  while  the  Supplemental
Interest Trust is in existence,  unless (1) such Plan is an accredited  investor
within  the  meaning of the  Exemption  and (2) such  acquisition  or holding is
eligible for the exemptive relief  available under PTCE 84-14 (for  transactions
by independent "qualified professional asset managers"), 91-38 (for transactions
by bank  collective  investment  funds),  90-1 (for  transactions  by  insurance
company pooled separate accounts),  95-60 (for transactions by insurance company
general  accounts)  or 96-23  (for  transactions  effected  by  "in-house  asset
managers"). For so long as the Supplemental Interest Trust is in existence, each
beneficial  owner of an Offered  Certificate or any interest  therein,  shall be
deemed to have  represented,  by virtue of its  acquisition  or  holding  of the
Offered  Certificate,  or interest therein,  that either (i) it is not a Plan or
(ii) (A) it is an  accredited  investor  within the meaning of the Exemption and
(B) the  acquisition  and holding of such  Certificate and the separate right to
receive  payments  from the  Supplemental  Interest  Trust are  eligible for the
exemptive  relief available under one of the five prohibited  transaction  class
exemptions enumerated above.

      A fiduciary of or other investor of Plan assets  contemplating  purchasing
an Offered  Certificate  should  consult  their  legal  counsel  concerning  the
availability  of, and the scope of relief  provided  by, the  Exemption  and the
enumerated class Exemptions.

      Each beneficial  owner of a Mezzanine  Certificate or any interest therein
that is acquired after the termination of the Supplemental Interest Trust (which
holds the Interest Rate Swap Agreement) shall be deemed to have represented,  by
virtue of its  acquisition or holding of that  certificate or interest  therein,
that either (i) it is not a plan  investor,  (ii) it has acquired and is holding
such  subordinated  certificate  in  reliance  on the  Exemption,  and  that  it
understands  that  there  are  certain  conditions  to the  availability  of the
Exemption,  including that the  subordinated  certificate  must be rated, at the
time of  purchase,  not lower than  "BBB-"  (or its  equivalent)  by  Standard &
Poor's,  Fitch Ratings or Moody's or (iii) (1) it is an insurance  company,  (2)
the source of funds used to acquire or hold the certificate or interest  therein
is an "insurance company general account", as such term is defined in Prohibited
Transaction Class Exemption ("PTCE") 95-60, and (3) the conditions in Sections I
and III of PTCE 95-60 have been satisfied.

      If any Offered  Certificate,  or any interest therein, is acquired or held
in violation of the  provisions of this section,  the next  preceding  permitted
beneficial  owner will be treated as the beneficial  owner of that  certificate,
retroactive  to the date of  transfer to the  purported  beneficial  owner.  Any
purported   beneficial  owner  whose   acquisition  or  holding  of  an  Offered
Certificate, or interest therein, was effected in violation of the provisions of
this section  shall  indemnify to the extent  permitted by law and hold harmless
the Depositor,  the Sponsor, the Master Servicer,  the Servicer, the Underwriter
and the  Trustee  from and  against any and all  liabilities,  claims,  costs or
expenses incurred by such parties as a result of such acquisition or holding.

      Plan fiduciaries are encouraged to consult their legal counsel  concerning
the  availability  of, and scope of relief  provided by, the  Exemption  and the
enumerated class  exemptions,  and the potential  consequences in their specific
circumstances,  prior to  making  an  investment  in the  Offered  Certificates.
Moreover,  each Plan  fiduciary  should  determine  whether  under  the  general
fiduciary standards of investment prudence and diversification, an investment in
the Offered  Certificates is appropriate  for the Plan,  taking into account the
overall  investment  policy  of the  Plan  and  the  composition  of the  Plan's
investment portfolio.

      The sale of any class of Offered Certificates to a Plan is in no respect a
representation by the Depositor, the Trustee, the Securities Administrator,  the
Master  Servicer,  the Servicer or the Underwriter that such an investment meets
all relevant legal  requirements  with respect to investments by Plans generally
or any  particular  Plan, or that such an investment  is  appropriate  for Plans
generally or any particular Plan.

                                     ANNEX I

          GLOBAL CLEARANCE AND SETTLEMENT AND DOCUMENTATION PROCEDURES

      Except in certain limited circumstances,  the Offered Certificates will be
offered  globally  (the  "Global  Securities")  and  will be  available  only in
book-entry  form.  Investors  in the  Global  Securities  may hold  such  Global
Securities through any of DTC,  Clearstream or Euroclear.  The Global Securities
will be  tradable  as home  market  instruments  in both the  European  and U.S.
domestic  markets.  Initial  settlement and all secondary  trades will settle in
same-day funds.

      Secondary  market trading  between  investors  holding  Global  Securities
through  Clearstream  and  Euroclear  will be  conducted  in the ordinary way in
accordance  with their normal rules and operating  procedures  and in accordance
with conventional eurobond practice (i.e., seven calendar day settlement).

      Secondary  market trading  between  investors  holding  Global  Securities
through DTC will be conducted  according to the rules and procedures  applicable
to U.S. corporate debt obligations.

      Secondary  cross-market  trading between  Clearstream or Euroclear and DTC
Participants holding Certificates will be effected on a delivery-against-payment
basis through the respective  Depositories of Clearstream and Euroclear (in such
capacity) and as DTC Participants.

      Non-U.S. holders (as described below) of Global Securities will be subject
to U.S.  withholding  taxes unless such holders  meet certain  requirements  and
deliver appropriate U.S. tax documents to the securities clearing  organizations
or their participants.

INITIAL SETTLEMENT

      All Global  Securities  will be held in book-entry form by DTC in the name
of Cede & Co. as nominee of DTC.  Investors'  interests in the Global Securities
will be represented  through  financial  institutions  acting on their behalf as
direct and indirect Participants in DTC. As a result,  Clearstream and Euroclear
will hold  positions on behalf of their  participants  through their  respective
Depositories,  which  in turn  will  hold  such  positions  in  accounts  as DTC
Participants.

      Investors electing to hold their Global Securities through DTC will follow
the settlement practices applicable to conventional eurobonds, except that there
will be no temporary  global  security and no  "lock-up" or  restricted  period.
Investor  securities  custody  accounts  will be  credited  with their  holdings
against payment in same-day funds on the settlement date.

      Investors electing to hold their Global Securities through  Clearstream or
Euroclear  accounts  will  follow  the  settlement   procedures   applicable  to
conventional  eurobonds,  except that there will be no temporary global security
and no "lock-up" or restricted period. Global Securities will be credited to the
securities  custody  accounts on the settlement date against payment in same-day
funds.

SECONDARY MARKET TRADING

      Since the purchaser  determines the place of delivery,  it is important to
establish  at the time of the  trade  where  both the  purchaser's  and  sellers
accounts are located to ensure that  settlement can be made on the desired value
date.

      TRADING  BETWEEN DTC  PARTICIPANTS.  Secondary  market trading between DTC
Participants  will be settled using the procedures  applicable to prior mortgage
loan asset-backed certificates issues in same-day funds.


                                      I-1


      TRADING  BETWEEN  CLEARSTREAM  AND/OR  EUROCLEAR  PARTICIPANTS.  Secondary
market trading between Clearstream  Participants or Euroclear  Participants will
be settled using the procedures applicable to conventional eurobonds in same-day
funds.

      TRADING  BETWEEN DTC SELLER AND CLEARSTREAM OR EUROCLEAR  PURCHASER.  When
Global Securities are to be transferred from the account of a DTC Participant to
the  account  of a  Clearstream  Participant  or a  Euroclear  Participant,  the
purchaser  will  send   instructions  to  Clearstream  or  Euroclear  through  a
Clearstream Participant or Euroclear Participant at least one business day prior
to settlement. Clearstream or Euroclear will instruct the respective Depository,
as the case may be, to receive the Global  Securities  against payment.  Payment
will include  interest  accrued on the Global  Securities from and including the
last coupon payment date to and excluding the  settlement  date, on the basis of
the actual  number of days in such accrual  period and a year assumed to consist
of 360 days. For  transactions  settling on the 31st of the month,  payment will
include  interest accrued to and excluding the first day of the following month.
Payment will then be made by the respective  Depository of the DTC Participant's
account against  delivery of the Global  Securities.  After  settlement has been
completed,  the Global  Securities  will be credited to the respective  clearing
system and by the clearing system, in accordance with its usual  procedures,  to
the Clearstream Participant's or Euroclear Participant's account. The securities
credit  will  appear  the next day  (European  time)  and the cash  debt will be
back-valued to, and the interest on the Global  Securities will accrue from, the
value date (which would be the  preceding  day when  settlement  occurred in New
York).  If  settlement is not  completed on the intended  value date (i.e.,  the
trade fails),  the  Clearstream or Euroclear cash debt will be valued instead as
of the actual settlement date.

      Clearstream  Participants  and  Euroclear  Participants  will need to make
available  to the  respective  clearing  systems the funds  necessary to process
same-day funds  settlement.  The most direct means of doing so is to preposition
funds for settlement,  either from cash on hand or existing lines of credit,  as
they would for any settlement  occurring within Clearstream or Euroclear.  Under
this  approach,  they may take on credit  exposure to  Clearstream  or Euroclear
until the Global Securities are credited to their accounts one day later.

      As an  alternative,  if  Clearstream  or Euroclear  has extended a line of
credit to them, Clearstream Participants or Euroclear Participants can elect not
to  preposition  funds and allow that  credit  line to be drawn upon the finance
settlement.   Under  this  procedure,   Clearstream  Participants  or  Euroclear
Participants  purchasing Global Securities would incur overdraft charges for one
day,  assuming  they  cleared  the  overdraft  when the Global  Securities  were
credited to their accounts.  However,  interest on the Global  Securities  would
accrue from the value date.  Therefore,  in many cases the investment  income on
the Global Securities earned during that one-day period may substantially reduce
or offset the amount of such overdraft charges, although this result will depend
on each Clearstream  Participant's or Euroclear Participant's particular cost of
funds.

      Since the settlement is taking place during New York business  hours,  DTC
Participants can employ their usual procedures for sending Global  Securities to
the respective European  Depository for the benefit of Clearstream  Participants
or Euroclear Participants. The sale proceeds will be available to the DTC seller
on the settlement date. Thus, to the DTC Participants a cross-market transaction
will settle no differently than a trade between two DTC Participants.

      TRADING BETWEEN CLEARSTREAM OR EUROCLEAR SELLER AND DTC PURCHASER.  Due to
time zone  differences in their favor,  Clearstream  Participants  and Euroclear
Participants  may employ their  customary  procedures for  transactions in which
Global  Securities  are to be transferred  by the  respective  clearing  system,
through the respective  Depository,  to a DTC Participant.  The seller will send
instructions  to Clearstream or Euroclear  through a Clearstream  Participant or
Euroclear  Participant at least one business day prior to  settlement.  In these
cases  Clearstream  or Euroclear  will instruct the  respective  Depository,  as
appropriate,  to deliver the Global Securities to the DTC


                                      I-2


Participant's account against payment.  Payment will include interest accrued on
the  Global  Securities  from and  including  the  last  coupon  payment  to and
excluding the settlement  date on the basis of the actual number of days in such
accrual  period and a year  assumed to  consist  of 360 days.  For  transactions
settling on the 31st of the month,  payment will include interest accrued to and
excluding  the  first  day of the  following  month.  The  payment  will then be
reflected in the account of the Clearstream Participant or Euroclear Participant
the  following  day,  and  receipt  of the  cash  proceeds  in  the  Clearstream
Participant's  or Euroclear  Participant's  account would be  back-valued to the
value date (which would be the preceding  day, when  settlement  occurred in New
York). Should the Clearstream  Participant or Euroclear  Participant have a line
of  credit  with  its  respective  clearing  system  and  elect to be in debt in
anticipation of receipt of the sale proceeds in its account,  the back-valuation
will extinguish any overdraft  incurred over that one-day period.  If settlement
is not completed on the intended value date (i.e., the trade fails),  receipt of
the cash proceeds in the Clearstream  Participant's  or Euroclear  Participant's
account would instead be valued as of the actual settlement date.

      Finally,  day traders that use  Clearstream or Euroclear and that purchase
Global Securities from DTC Participants For deliver to Clearstream  Participants
or Euroclear Participants should note that these trades would automatically fail
on the sale side unless affirmative action were taken. At least three techniques
should be readily available to eliminate this potential problem:

      (a)  borrowing  through  Clearstream  or Euroclear  for one day (until the
purchase  side of the day trade is reflected in their  Clearstream  or Euroclear
accounts) in accordance with the clearing system's customary procedures;

      (b) borrowing the Global  Securities in the U.S. from a DTC Participant no
later than one day prior to settlement,  which would give the Global  Securities
sufficient  time to be reflected in their  Clearstream  or Euroclear  account in
order to settle the sale side of the trade; or

      (c)  staggering the value dates for the buy and sell sides of the trade so
that the value date for the purchase  from the DTC  Participant  is at least one
day  prior to the  value  date for the sale to the  Clearstream  Participant  or
Euroclear Participant.

CERTAIN U.S. FEDERAL INCOME TAX DOCUMENTATION REQUIREMENTS

      A  beneficial  owner  of  Global  Securities  holding  securities  through
Clearstream  or Euroclear  (or through DTC if the holder has an address  outside
the U.S.) will be subject to the 30% U.S. withholding tax that generally applies
to payments of interest  (including  original issue discount) on registered debt
issued by U.S. Persons, unless (i) each clearing system, bank or other financial
institution that holds customers' securities in the ordinary course of its trade
or business in the chain of intermediaries between such beneficial owner and the
U.S.  entity  required to withhold tax complies  with  applicable  certification
requirements  and (ii) such beneficial owner takes one of the following steps to
obtain an exemption or reduced tax rate:

      EXEMPTION FOR NON-U.S. PERSONS (FORM W-8BEN).  Beneficial owners of Global
Securities  that are non-U.S.  Persons can obtain a complete  exemption from the
withholding tax by filing a signed Form W-8BEN (Certificate of Foreign Status of
Beneficial Owner for United States Tax Withholding). If the information shown on
Form W-8BEN  changes,  a new Form  W-8BEN  must be filed  within 30 days of such
change.

      EXEMPTION FOR NON-U.S.  PERSONS WITH  EFFECTIVELY  CONNECTED  INCOME (FORM
W-8ECI). A non-U.S. Person, including a non-U.S. corporation or bank with a U.S.
branch,  for  which the  interest  income is  ineffectively  connected  with its
conduct of a trade or business  in the United  States,  can obtain an  exemption
from the withholding tax by filing Form W-8ECI  (Certificate of


                                      I-3


Foreign  Person's  Claim for Exemption from  Withholding  on Income  Effectively
Connected with the Conduct of a Trade or Business in the United States).

      EXEMPTION  OR  REDUCED  RATE  FOR  NON-U.S.  PERSONS  RESIDENT  IN  TREATY
COUNTRIES (FORM W-8BEN).  Non-U.S.  Persons that are Certificate Owners residing
in a  country  that has a tax  treaty  with the  United  States  can  obtain  an
exemption  or reduced tax rate  (depending  on the treaty  terms) by filing Form
W-8BEN  (Certificate of Foreign Status of Beneficial Owner for United States Tax
Withholding). Form W-8BEN may be filed by the Certificate Owners or his agent.

      EXEMPTION  OR REDUCED RATE FOR  NON-U.S.  PERSONS  SUBJECT TO SPECIAL U.S.
FEDERAL  INCOME TAX RULES  (FORM  W-8EXP).  A non-U.S.  Person that is a foreign
government,  international organization,  foreign central bank of issue, foreign
tax-exempt  organization,  foreign  private  foundation  or government of a U.S.
possession  may obtain an  exemption  or reduced  tax rate on certain  income by
filing  Form  W-8EXP   (Certificate  of  Foreign  Government  or  Other  Foreign
Organization for United States Tax Withholding).

      EXEMPTION FOR U.S.  PERSONS (FORM W-9). U.S. Persons can obtain a complete
exemption  from the  withholding  tax by filing  Form W-9  (Payers  Request  for
Taxpayer Identification Number and Certification).

      U.S. FEDERAL INCOME TAX REPORTING  PROCEDURE.  The Certificate  Owner of a
Global Security files by submitting the  appropriate  form to the person through
whom it holds (the clearing  agency,  in the case of persons holding directly on
the books of the  clearing  agency).  Form W-8BEN and Form W-8ECI are  effective
until the third succeeding calendar year from the date such form is signed.

      The term  "U.S.  Person"  means (i) a citizen  or  resident  of the United
States, (ii) a corporation, partnership or other entity treated as a corporation
or partnership  for United States  federal  income tax purposes  organized in or
under the laws of the  United  States or any state  thereof or the  District  of
Columbia (unless,  in the case of a partnership,  Treasury  regulations  provide
otherwise),  (iii) an estate the income of which is  includible  in gross income
for United States tax purposes,  regardless of its source,  or (iv) a trust if a
court within the United States is able to exercise primary  supervision over the
administration of the trust and one or more United States persons have authority
to control all substantial decisions of the trust. Notwithstanding the preceding
sentence,  to the extent  provided in Treasury  regulations,  certain  trusts in
existence on August 20,1996,  and treated as United States persons prior to such
date, that elect to continue to be treated as United States persons will also be
a U.S.  Person.  This  summary  does not deal with all  aspects of U.S.  Federal
income tax  withholding  that may be relevant  to foreign  holders of the Global
Securities. Investors are advised to consult their own tax advisors for specific
tax advice concerning their holding and disposing of the Global Securities.

        THE  FOLLOWING   INFORMATION,   WHICH  YOU  SHOULD  CAREFULLY  CONSIDER,
IDENTIFIES CERTAIN  SIGNIFICANT SOURCES OF RISK ASSOCIATED WITH AN INVESTMENT IN
THE  CERTIFICATES  AND  THE  NOTES.  YOU  SHOULD  ALSO  CAREFULLY  CONSIDER  THE
INFORMATION SET FORTH UNDER "RISK FACTORS" IN THE PROSPECTUS SUPPLEMENT.

                            things,  a  mortgagor's  credit  history,  repayment
                            ability and debt service-to-income ratio, as well as
                            the value,  type and use of the mortgaged  property.
                            As  further   described  in  this  prospectus,   the
                            underwriting  standards  of the  originators  do not
                            conform to Fannie Mae and Freddie Mac guidelines.

                            In  addition,   mortgage  loans  originated  by  the
                            originators  generally bear higher rates of interest
                            than mortgage  loans  originated in accordance  with
                            Fannie  Mae  and  Freddie  Mac  guidelines  and  may
                            experience  rates of  delinquency,  foreclosure  and

                            properties   may  have  a  greater   effect  on  the
                            delinquency,   foreclosure,   bankruptcy   and  loss

                            The mortgage loans are also subject to federal laws,

                              o   the   Federal    Truth-in-Lending    Act   and
                                  Regulation  Z  promulgated  thereunder,  which
                                  require certain  disclosures to the mortgagors
                                  regarding  the terms of the mortgage  loans or
                                  contracts;

                              o   the   Equal   Credit   Opportunity   Act   and
                                  Regulation  B  promulgated  thereunder,  which
                                  prohibit  discrimination  on the basis of age,
                                  race,  color, sex,  religion,  marital status,
                                  national origin,  receipt of public assistance
                                  or  the   exercise  of  any  right  under  the
                                  Consumer   Credit   Protection   Act,  in  the

                                  to the mortgagor's credit experience; and

                                  Monetary  Control Act of 1980,  which preempts
                                  certain state usury laws.

                            Violations  of certain  provisions  of these federal
                            and state laws may limit the ability of the servicer
                            to  collect  all  or  part  of the  principal  of or
                            interest on the related  mortgage loans or contracts
                            and in addition  could  subject the trust to damages
                            and administrative  enforcement.  In particular, the
                            failure of the  originators  to comply with  certain
                            requirements of the Federal Truth-in-Lending Act, as
                            implemented by Regulation Z, could subject the trust
                            to monetary penalties, and result in the mortgagors'
                            rescinding the mortgage  loans or contracts  against
                            the issuing entity. In addition to federal law, some
                            states  have   enacted,   or  may  enact,   laws  or
                            regulations   that   prohibit   inclusion   of  some
                            provisions in mortgage  loans or contracts that have
                            interest  rates or  origination  costs in  excess of
                            prescribed  levels,  and require that  mortgagors be
                            given certain  disclosures prior to the consummation
                            of the mortgage  loans or contracts and restrict the
                            servicer's  ability  to  foreclose  in  response  to
                            mortgagor  defaults.  The failure of the originators
                            to comply with these laws could subject the trust to
                            significant monetary penalties,  could result in the
                            mortgagors   rescinding   the   mortgage   loans  or
                            contracts   against  the  trust   and/or  limit  the

                DESCRIPTION OF THE ISSUING ENTITIES' TRUST FUNDS

ASSETS

        The primary  assets of each issuing  entity's  trust fund (the "Assets")
will include some or all of the following types of assets:

        o   mortgage  loans  on  single  family  and   multifamily   residential
            properties,  which may include Home Equity Loans,  home  improvement
            contracts  and  Land  Sale  Contracts   (each  as  defined  in  this
            prospectus),  commercial  properties,  unimproved land and mixed-use
            residential and commercial properties;

        o   home improvement  installment  sales contracts or installment  loans
            that are unsecured called unsecured home improvement Loans;

        o   manufactured  housing installment sale contracts or installment loan
            agreements referred to as contracts;

        o   any  combination of "fully  modified  pass-through"  mortgage-backed
            certificates   guaranteed  by  the  Government   National   Mortgage
            Association   ("Ginnie  Mae"),   guaranteed  mortgage   pass-through
            securities   issued  by  Fannie  Mae  ("Fannie  Mae")  and  mortgage
            participation  certificates issued by the Federal Home Loan Mortgage
            Corporation ("Freddie Mac") (collectively, "Agency Securities");

        o   previously issued asset-backed certificates, collateralized mortgage
            obligations or participation  certificates  (each, and collectively,
            "Mortgage  Securities")  evidencing  interests in, or collateralized
            by, mortgage loans or Agency Securities; or

        o   a combination of mortgage loans,  unsecured home improvement  loans,
            contracts, Agency Securities and/or Mortgage Securities.

        The mortgage  loans will not be guaranteed or insured by ACE  Securities
Corp. or any of its affiliates. The mortgage loans will be guaranteed or insured
by a governmental  agency or  instrumentality or other person only if and to the
extent  expressly  provided in the  prospectus  supplement.  The depositor  will
select each Asset to include in an issuing  entity's trust fund from among those
it has purchased,  either directly or indirectly, from a prior holder (an "Asset
Seller"),  which may be an affiliate of the depositor and which prior holder may
or may not be the  originator  of that  mortgage  loan.  As to  each  series  of
securities,  the mortgage  loans will be selected for  inclusion in the mortgage
pool  based on rating  agency  criteria,  compliance  with  representations  and
warranties,  and  conformity  to criteria  relating to the  characterization  of
securities for tax, ERISA, SMMEA, Form S-3 eligibility and other legal purposes.

        The Assets  included in the issuing  entity's trust fund for your series
may be subject to various types of payment provisions:

        o   "Level  Payment  Assets,"  which  may  provide  for the  payment  of
            interest, and full repayment of principal, in level monthly payments
            with a fixed rate of interest computed on their declining  principal
            balances;

                                       4



        o   "Adjustable Rate Assets," which may provide for periodic adjustments
            to their rates of interest to equal the sum of a fixed margin and an
            index;

        o   "Buy Down  Assets,"  which are  Assets  for  which  funds  have been
            provided by someone  other than the related  borrowers to reduce the
            borrowers'   monthly   payments   during  the  early   period  after
            origination of those Assets;

        o   "Increasing Payment Assets," as described below;

        o   "Interest   Reduction   Assets,"  which  provide  for  the  one-time
            reduction of the interest rate payable on these Assets;

        o   "GEM Assets" which provide for (1) monthly payments during the first
            year after  origination that are at least sufficient to pay interest
            due on these Assets,  and (2) an increase in those monthly  payments
            in later years at a  predetermined  rate resulting in full repayment
            over a shorter  term than the  initial  amortization  terms of those
            Assets;

        o   "GPM  Assets"  which  allow for  payments  during a portion of their
            terms  which are or may be less than the amount of  interest  due on
            their unpaid  principal  balances,  and this unpaid interest will be
            added to the  principal  balances of those  Assets and will be paid,
            together with interest on the unpaid interest, in later years;

        o   "Step-up Rate Assets" which provide for interest rates that increase
            over time;

        o   "Balloon Payment Assets;"

        o   "Convertible  Assets" which are  Adjustable  Rate Assets  subject to
            provisions  pursuant to which,  subject to limitations,  the related
            borrowers may exercise an option to convert the adjustable  interest
            rate to a fixed interest rate; and

        o   "Bi-weekly  Assets,"  which  provide  for  payments  to be  made  by
            borrowers on a bi-weekly basis.

        An  "Increasing  Payment  Asset" is an Asset that  provides  for monthly
payments that are fixed for an initial  period to be specified in the prospectus
supplement and which increase thereafter (at a predetermined rate expressed as a
percentage of the monthly payment during the preceding  payment period,  subject
to any caps on the amount of any single monthly  payment  increase) for a period
to be specified in the prospectus supplement from the date of origination, after
which the  monthly  payment  is fixed at a  level-payment  amount so as to fully
amortize the Asset over its remaining  term to maturity.  The scheduled  monthly
payment for an Increasing  Payment Asset is the total amount required to be paid
each month in accordance with its terms and equals the sum of (1) the borrower's
monthly payments referred to in the preceding  sentence and (2) payments made by
the  respective  servicers  pursuant  to  buy-down  or subsidy  agreements.  The
borrower's initial monthly payments for each Increasing Payment Asset are set at
the  level-payment  amount  that would  apply to an  otherwise  identical  Level
Payment Asset having an interest rate some number of percentage points below the
Asset Rate of that Increasing  Payment Asset. The borrower's monthly payments on
each Increasing Payment Asset, together with any payments made on the Increasing
Payment  Asset  by  the  related  servicers  pursuant  to  buy-down  or  subsidy
agreements, will in all cases be sufficient to allow payment of accrued interest
on the Increasing  Payment Asset at the related interest rate,  without negative
amortization.  A borrower's monthly payments on an Increasing Payment Asset may,
however,  not be sufficient to result in

                                       5



any reduction of the principal balance of that Asset until after the period when
those payments may be increased.

        The  Notes  or   Certificates,   as  applicable   (as  defined  in  this
prospectus),  will be  entitled  to payment  only from the assets of the related
issuing entity and will not be entitled to payments from the assets of any other
issuing entity established by the depositor. The assets of an issuing entity may
consist of  certificates  representing  beneficial  ownership  interests  in, or
indebtedness  of, another issuing entity that contains the Assets,  if specified
in the prospectus supplement.

MORTGAGE LOANS

        GENERAL

        Each mortgage loan will  generally be secured by a lien on (1) a one- to
four-family  residential  property (including a manufactured home) or a security
interest in shares issued by a cooperative housing corporation (a "Single Family
Property"), (2) a primarily residential rental property that consists of five or
more residential dwelling units ("Multifamily Property"),  (3) a retail, office,
agricultural  or  other  commercial  property,  including  but  not  limited  to
partially  improved  or  unimproved   ("Commercial   Property"),   (4)  a  mixed
residential/commercial  property ("Mixed-Use  Property" and together with Single
Family Property,  Multifamily Property and Commercial  Property,  the "Mortgaged
Properties").  The  mortgage  loans  will be  secured  by  first  and/or  junior
mortgages or deeds of trust or other  similar  security  instruments  creating a
first or junior lien on Mortgaged Property.

        The Mortgaged Properties may also include:

        o   Apartment  buildings  owned  by  cooperative  housing   corporations
            ("Cooperatives"); and

        o   Leasehold  interests  in  properties,  the title to which is held by
            third party lessors.  The term of these  leaseholds  will exceed the
            term of the  related  mortgage  note by at least  five years or some
            other time period specified in the prospectus supplement.

        The mortgage loans may include:

        o   Closed-end  and/or  revolving home equity loans or balances of these
            home equity loans ("Home Equity Loans");

        o   Secured home  improvement  installment  sales  contracts and secured
            installment  loan agreements,  known as home improvement  contracts;
            and

        o   Mortgage loans  evidenced by contracts  ("Land Sale  Contracts") for
            the sale of  properties  pursuant to which the borrower  promises to
            pay the amount due on the  mortgage  loans to the holder of the Land
            Sale  Contract  with fee title to the related  property held by that
            holder  until the  borrower  has made all of the  payments  required
            pursuant  to that Land  Sale  Contract,  at which  time fee title is
            conveyed to the borrower.

        The  originator of each mortgage loan will have been a person other than
the depositor.  The prospectus  supplement will indicate if any originator is an
affiliate of the  depositor.  The  mortgage  loans will be evidenced by mortgage
notes secured by mortgages,  deeds of trust or other security  instruments  (the
"Mortgages") creating a lien on the Mortgaged Properties. The

                                       6



Mortgaged  Properties  will be  located  in any  one of the  fifty  states,  the
District of  Columbia,  Guam,  Puerto Rico or any other  territory of the United
States. If provided in the prospectus supplement, the mortgage loans may include
loans  insured by the Federal  Housing  Administration  (the "FHA") or partially
guaranteed by the Veteran's  Administration  (the "VA"). See "--FHA Loans and VA
Loans" below.

        FICO SCORES

        The  FICO  Score  is a  statistical  ranking  of  likely  future  credit
performance  developed by Fair,  Isaac & Company  ("Fair,  Isaac") and the three
national credit  repositories-Equifax,  Trans Union and First American (formerly
Experian  which was  formerly  TRW).  The FICO Scores  available  from the three
national credit  repositories  are calculated by the assignment of weightings to
the most predictive data collected by the credit repositories and range from the
300's to the 900's. Although the FICO Scores are based solely on the information
at the particular  credit  repository,  such FICO Scores have been calibrated to
indicate the same level of credit risk regardless of which credit  repository is
used. The FICO Scores is used along with, but not limited to,  mortgage  payment
history, seasoning on bankruptcy and/or foreclosure, and is not a substitute for
the underwriter's judgment.

        LOAN-TO-VALUE RATIO

        The  "Loan-to-Value  Ratio" of a mortgage loan at any particular time is
the ratio (expressed as a percentage) of the then outstanding  principal balance
of the mortgage loan to the Value of the related Mortgaged Property. The "Value"
of a Mortgaged Property, other than for Refinance Loans, is generally the lesser
of (a) the appraised value determined in an appraisal obtained by the originator
at  origination  of that  loan  and (b)  the  sales  price  for  that  property.
"Refinance Loans" are loans made to refinance  existing loans.  Unless otherwise
specified in the  prospectus  supplement,  the Value of the  Mortgaged  Property
securing a  Refinance  Loan is the  appraised  value of the  Mortgaged  Property
determined in an appraisal  obtained at the time of origination of the Refinance
Loan.  The value of a Mortgaged  Property as of the date of initial  issuance of
the related series may be less than the Value at origination  and will fluctuate
from time to time based upon changes in economic  conditions and the real estate
market.

        PRIMARY MORTGAGE INSURANCE

        Except  in the  case  of  high  loan-to-value  loans  and  as  otherwise
specified in the related  prospectus  supplement,  each  mortgage  loan having a
loan-to-value  ratio at  origination in excess of 80%, is required to be covered
by a primary mortgage guaranty insurance policy insuring against default on such
mortgage loan as to at least the principal  amount thereof  exceeding 75% of the
value of the  mortgaged  property at  origination  of the  mortgage  loan.  This
insurance  must remain in force at least until the mortgage loan  amortizes to a
level that would  produce a  loan-to-value  ratio lower than 80%.  See  "Primary
Mortgage Insurance Policies".

        MORTGAGE LOAN INFORMATION IN THE PROSPECTUS SUPPLEMENTS

        Your  prospectus  supplement will contain  information,  as of the dates
specified in that  prospectus  supplement and to the extent then  applicable and
specifically  known  to the  depositor,  with  respect  to the  mortgage  loans,
including:

        o   the total outstanding  principal  balance and the largest,  smallest
            and average  outstanding  principal balance of the mortgage loans as
            of, unless otherwise  specified in that prospectus  supplement,  the
            close of business on the first day of the month of  formation of the
            related issuing entity (the "Cut-off Date");

                                       7



        o   the type of property securing the mortgage loans;

        o   the  weighted  average (by  principal  balance) of the  original and
            remaining terms to maturity of the mortgage loans;

        o   the range of maturity dates of the mortgage loans;

        o   the range of the Loan-to-Value Ratios at origination of the mortgage
            loans;

        o   the  mortgage  rates or range of  mortgage  rates  and the  weighted
            average mortgage rate borne by the mortgage loans;

        o   the state or states in which most of the  Mortgaged  Properties  are
            located;

        o   information  regarding  the  prepayment  provisions,  if any, of the
            mortgage loans;

        o   for mortgage loans with adjustable mortgage rates ("ARM Loans"), the
            index,  the frequency of the adjustment  dates, the range of margins
            added to the index, and the maximum mortgage rate or monthly payment
            variation at the time of any  adjustment of and over the life of the
            ARM Loan;

        o   information  regarding the payment  characteristics  of the mortgage
            loans, including balloon payment and other amortization provisions;

        o   the number of mortgage  loans that are  delinquent and the number of
            days or  ranges  of the  number  of days  those  mortgage  loans are
            delinquent; and

        o   the material underwriting standards used for the mortgage loans.

If  specific  information  respecting  the  mortgage  loans  is  unknown  to the
depositor at the time the Notes or  Certificates,  as applicable,  are initially
offered, more general information of the nature described above will be provided
in the prospectus  supplement,  and specific  information will be set forth in a
report  that  will  be  available  to   purchasers   of  the  related  Notes  or
Certificates,  as applicable, at or before the initial issuance of that Security
and will be filed as part of a Current  Report  on Form 8-K with the  Securities
and  Exchange  Commission  (the  "Commission")  within  fifteen  days after that
initial issuance.  In the event that mortgage loans are added to or deleted from
the issuing entity after the date of the related prospectus supplement but on or
before  the  date  of  issuance  of  the   securities   if  any  material   pool
characteristic  differs  by 5% or more from the  description  in the  prospectus
supplement,  revised  disclosure will be provided either in a supplement or in a
Current Report on Form 8-K.

        The  prospectus  supplement  will  specify  whether the  mortgage  loans
include (1) Home Equity Loans, which may be secured by Mortgages that are junior
to other liens on the related  Mortgaged  Property  and/or (2) home  improvement
contracts originated by a home improvement  contractor and secured by a mortgage
on the related mortgaged property that is junior to other liens on the mortgaged
property.  The home improvements  purchased with the home improvement  contracts
typically include  replacement  windows,  house siding,  roofs,  swimming pools,
satellite dishes,  kitchen and bathroom  remodeling goods, solar heating panels,
patios,  decks,  room  additions and garages.  The  prospectus  supplement  will
specify  whether the home  improvement  contracts  are FHA loans and, if so, the
limitations on any FHA insurance.  In addition,  the prospectus  supplement will
specify whether the mortgage loans contain some mortgage loans evidenced by Land
Sale Contracts.

        PAYMENT PROVISIONS OF THE MORTGAGE LOANS

        All of the  mortgage  loans will  provide  for  payments  of  principal,
interest or both, on due dates that occur monthly, quarterly or semi-annually or
at some other  interval as is  specified  in the  prospectus  supplement  or for
payments in another manner described in the prospectus supplement. Each mortgage
loan may  provide  for no accrual of  interest or for accrual of interest on the
mortgage  loan at a mortgage  rate that is fixed  over its term or that  adjusts
from  time to  time,  or that may be  converted  from an  adjustable  to a fixed
mortgage  rate or a different  adjustable  mortgage  rate, or from a fixed to an
adjustable  mortgage  rate,  from time to time  pursuant  to an  election  or as
otherwise  specified in the related  mortgage note, in each case as described in
the prospectus supplement. Each mortgage loan may provide for scheduled payments
to maturity or payments that adjust from time to time to accommodate  changes in
the mortgage  rate or to reflect the  occurrence  of  particular  events or that
adjust  on the  basis of  other  methodologies,  and may  provide  for  negative
amortization  or  accelerated  amortization,  in each case as  described  in the
prospectus  supplement.  Each mortgage loan may be fully amortizing or require a
balloon  payment due on its stated  maturity  date, in each case as described in
the  prospectus  supplement.  Each  mortgage  loan may contain  prohibitions  on
prepayment (a "Lock-out Period" and, the date of expiration thereof, a "Lock-out
Date")  or  require  payment  of a premium  or a yield  maintenance  penalty  (a
"Prepayment Premium") in connection with a prepayment, in each case as described
in the prospectus supplement.  If the holders of any class or classes of Offered
Notes or Offered Certificates,  as applicable,  are entitled to all or a portion
of any Prepayment  Premiums  collected from the mortgage  loans,  the prospectus
supplement will specify the method or methods by which any of these amounts will
be allocated. See "--Assets" above.

        HELOCS

        As more fully described in the prospectus supplement, the mortgage loans
may consist,  in whole or in part, of revolving Home Equity Loans or balances of
these  Home  Equity  Loans  ("HELOCs").   Interest  on  each  HELOC,   excluding
introductory rates offered from time to time during promotional  periods, may be
computed and payable monthly on the average daily outstanding  principal balance
of that loan. From time to time before the expiration of the related draw period
specified in a HELOC, principal amounts on that HELOC may be drawn down (up to a
maximum  amount  as set  forth  in the  prospectus  supplement)  or  repaid.  If
specified in the prospectus supplement,  new draws by borrowers under the HELOCs
will automatically become part of the issuing entity described in the prospectus
supplement. As a result, the total balance of the HELOCs will fluctuate from day
to day as new draws by borrowers  are added to the issuing  entity and principal
payments  are applied to those  balances and those  amounts will usually  differ
each day, as more  specifically  described in the prospectus  supplement.  Under
some  circumstances,  under a HELOC,  a borrower  may,  during the related  draw
period,  choose an interest  only payment  option,  during which the borrower is
obligated to pay only the amount of interest that accrues on the loan during the
billing cycle,  and may also elect to pay all or a portion of the principal.  An
interest  only  payment  option may  terminate  at the end of the  related  draw
period,  after which the borrower  must begin paying at least a minimum  monthly
portion of the average outstanding principal balance of the loan.

        UNSECURED HOME IMPROVEMENT LOANS

        The  unsecured  home  improvement  loans  may  consist  of  conventional
unsecured home improvement loans, unsecured installment loans and unsecured home
improvement  loans  that are FHA loans.  Except as  otherwise  described  in the
prospectus  supplement,  the  unsecured  home  improvement  loans  will be fully
amortizing and will bear interest at a fixed or variable annual percentage rate.

                                       9



        UNSECURED HOME IMPROVEMENT LOAN INFORMATION IN PROSPECTUS SUPPLEMENTS

        Each  prospectus  supplement will contain  information,  as of the dates
specified in the  prospectus  supplement  and to the extent then  applicable and
specifically  known  to  the  depositor,  with  respect  to any  unsecured  home
improvement loans, including:

        o   the total outstanding  principal  balance and the largest,  smallest
            and average  outstanding  principal  balance of the  unsecured  home
            improvement loans as of the applicable cut-off date;

        o   the  weighted  average,  by principal  balance,  of the original and
            remaining terms to maturity of the unsecured home improvement loans;

        o   the earliest and latest  origination  date and maturity  date of the
            unsecured home improvements loans;

        o   the  interest  rates or range of  interest  rates  and the  weighted
            average  interest  rates  borne by the  unsecured  home  improvement
            loans;

        o   the state or states in which most of the unsecured home  improvement
            loans were originated.

        o   information  regarding  the  prepayment  provisions,  if any, of the
            unsecured home improvement loans;

        o   with respect to the unsecured home improvement loans with adjustable
            interest rates,  called ARM unsecured home  improvement  loans,  the
            index,  the frequency of the adjustment  dates, the range of margins
            added to the index, and the maximum interest rate or monthly payment
            variation at the time of any adjustment thereof and over the life of
            the ARM unsecured home improvement loan;

        o   information  regarding the payment  characteristics of the unsecured
            home improvement loans;

        o   the number of unsecured home  improvement  loans that are delinquent
            and  the  number  of days  or  ranges  of the  number  of days  that
            unsecured home improvement loans are delinquent; and

        o   the material  underwriting  standards  used for the  unsecured  home
            improvement loans.

If specific  information  respecting  the unsecured  home  improvement  loans is
unknown to the depositor at the time Notes or Certificates,  as applicable,  are
initially offered,  more general  information of the nature described above will
be provided in the prospectus  supplement,  and specific information will be set
forth in a report that will be available to  purchasers  of the related Notes or
Certificates,  as applicable, at or before the initial issuance thereof and will
be filed as part of a  Current  Report  on Form 8-K with the  Commission  within
fifteen days after the related initial issuance.

        COMMERCIAL, MULTIFAMILY AND MIXED-USE MORTGAGE LOANS

        The mortgage loans may include mortgage loans secured by first or junior
mortgages,  deeds of trust or similar  security  instruments  on, or installment
contracts for the sale of, fee simple


                                       10



or  leasehold  interests  in  commercial  real  property  ("Commercial  Mortgage
Loans"), multifamily residential property ("Multifamily Mortgage Loans"), and/or
mixed residential and commercial  property  ("Mixed-Use  Mortgage  Loans"),  and
related property and interests.

        Certain of the Commercial,  Multifamily and Mixed-Use Mortgage Loans may
be simple  interest  loans,  and other mortgage loans may provide for payment of
interest in advance rather than in arrears.

        Commercial, Multifamily and Mixed-Use Mortgage Loans also may be secured
by one or more  assignments  of  leases  and  rents,  management  agreements  or
operating  agreements  relating to the  Mortgaged  Property and in some cases by
certain letters of credit, personal guarantees or both, and/or other collateral.
Pursuant to an assignment of leases and rents,  the related borrower assigns its
right,  title and interest as landlord  under each related  lease and the income
derived  therefrom to the related  lender,  while retaining a license to collect
the rents for so long as there is no  default.  If the  borrower  defaults,  the
license  terminates and the related lender is entitled to collect the rents from
tenants to be applied to the monetary obligations of the borrower. State law may
limit the  enforcement  of the  assignment of leases and rents by a lender until
the lender takes possession of the related mortgaged  property and a receiver is
appointed.  See  "Certain  Legal  Aspects  of the  Mortgage  Loans -- Leases and
Rents."

        Certain of the Commercial,  Multifamily and Mixed-Use Mortgage Loans may
require the borrower to make an initial escrow deposit and/or an ongoing monthly
deposit to fund a reserve for any of a variety of purposes, including repairs to
the  Mortgaged  Property  or  replacement  of  fixtures  or  equipment,   tenant
improvements,  and payment in the event of certain lease contingencies.  In some
cases,  the initial  deposit amount may have been funded with a letter of credit
in lieu of a cash deposit.  These amounts may be held in a custodial  account by
the applicable  servicer or an agent. The loan documents will generally  provide
for release of the reserve  amounts to the borrowers  from time to time upon the
satisfaction of certain conditions.

        Such  amounts may not  continue  to be  escrowed in the future.  In some
instances,  the borrower may be released  from its  obligation to fund a monthly
reserve upon  specified  conditions  being met, such as a maximum escrow balance
being  attained,  a certain date being  reached,  or a certain tenant signing or
extending  its lease.  Likewise,  there may be cases  where,  although  there is
currently  no monthly  escrow  amount,  one may be  required to be funded in the
future,  upon  certain  trigger  events.  In the event of default by a borrower,
amounts in a related  reserve  account may  generally  be applied to pay amounts
owed on the mortgage loan.

        Originators of Commercial,  Multifamily and Mixed-Use Mortgage Loans may
include,  among others,  commercial banks, savings and loan associations,  other
financial institutions, insurance companies or real estate developers, which may
apply varying  underwriting  criteria in connection  with  originating  mortgage
loans.

        Commercial,  multifamily  and mixed-use real estate lending is generally
viewed as exposing the lender to a greater risk of loss than one- to four-family
residential lending.  Commercial,  multifamily and mixed-use real estate lending
typically  involves  larger  loans to single  borrowers  or  groups  of  related
borrowers than residential one- to four-family mortgage loans. Furthermore,  the
repayment of loans secured by income producing properties is typically dependent
upon the successful  operation of the related real estate  project.  If the cash
flow from the project is reduced,  for  example,  if leases are not  obtained or
renewed,  the borrower's ability to repay the loan may be impaired.  Commercial,
multifamily  and mixed-use real estate can be affected  significantly  by supply
and  demand  in the  market  for the type of  property  securing  the loan  and,
therefore, may be subject to adverse economic conditions. Market values may vary
as a result of economic events or governmental  regulations  outside the control
of the  borrower or lender,  such as rent control  laws,  that affect the future
cash flow of the property. Corresponding to

                                       11



the greater  lending risk is a generally  higher  interest  rate  applicable  to
commercial, multifamily and mixed-use real estate lending.

        A  borrower  (or the  borrowers)  under  a  Commercial,  Multifamily  or
Mixed-Use  Mortgage Loan may be one or more  individuals or may be a corporation
or other registered  organization.  In some cases a borrower,  such as a special
purpose entity,  will have no material assets other than the mortgaged property.
In addition, in some cases the loans will have been made on a non-recourse basis
- -- in the event of default by the borrower, the only source of repayment will be
the proceeds of liquidation of the related property.

        There are various risks  associated  with different types of commercial,
multifamily and mixed-use loans.  For example,  the performance of a multifamily
loan and the value of the  related  mortgaged  property  may be affected by many
factors, including:

        o   local and regional economic conditions;

        o   the physical condition of the property;

        o   the types of services and amenities provided;

        o   the tenant  population  -- i.e.,  predominantly  students or elderly
            persons, or workers in a particular industry;

        o   availability of alternative rental properties;

        o   changes in the surrounding neighborhood;

        o   management;

        o   the level of mortgage interest rates;

        o   dependence upon government rent subsidies;

        o   any applicable rent control laws; and

        o   state and local regulations.

The  performance of a commercial  loan secured by one or more retail  properties
and the value of the related mortgaged property may be affected by many factors,
including:

        o   the quality and success of a retail property's tenants;

        o   closing of a major store in the  shopping  center  where the related
            property is located;

        o   changes in consumer preferences;

        o   declines in consumer spending;

        o   competition  from local  merchants  and from  catalog  and  internet
            retailers; and

        o   product obsolescence.

                                       12



The  performance of a commercial  loan secured by one or more office  properties
and the value of the related mortgaged property may be affected by many factors,
including:

        o   quality and nature of tenants;

        o   tenant  concentration  -- i.e.,  predominantly  high tech firms, law
            firms, government agencies, etc.;

        o   the physical condition of the property;

        o   the types of services and amenities provided;

        o   changes in the surrounding neighborhood; and

        o   availability of alternative office space.

The  performance  of a  commercial  loan  secured  by  one  or  more  industrial
properties  and the value of the related  mortgaged  property may be affected by
many factors, including:

        o   the design and adaptability of the building;

        o   success  or  failure  of  the  business  of  the  tenant,  which  is
            frequently the sole tenant of the property;

        o   availability of alternative space; and

        o   quality of the local and regional transportation system.

        The value of a commercial, multifamily or mixed-use property may also be
affected by a variety of other  factors.  In general,  such factors as location,
changing  demographics  or traffic  patterns,  increases in operating  expenses,
competitive factors and economic conditions generally,  among others, may affect
the value of a commercial property.

        Hospitals,  nursing homes and other health care properties may receive a
substantial  portion  of their  revenues  from  government  programs,  which are
subject to  statutory  and  regulatory  changes  and funding  limitations.  With
respect to commercial,  multifamily and mixed-use loans generally,  such factors
as the  management  skill,  experience  and financial  resources of the operator
(which  may  be  other  than  the  borrower),  national  and  regional  economic
conditions  and other  factors  may affect  the  ability  of  borrowers  to make
payments when due.

        Unimproved  land generates no current  income to support  payment of the
related  mortgage loan and other  expenses,  may prove to be unsuitable  for its
intended  purpose and may be  difficult  to sell for an amount at least equal to
the unpaid principal balance of the related loan.

        Leasehold  mortgages are subject to risks not  associated  with mortgage
loans  secured  by a lien on the fee  estate of a  borrower.  If the  borrower's
leasehold were to be terminated  upon a lease default,  the leasehold  mortgagee
would lose its security.  However,  such leases generally  require the lessor to
give the leasehold  mortgagee  notice of lessee  defaults and an  opportunity to
cure  them,  and  permit  the  leasehold  estate  to be  assigned  to and by the
leasehold mortgagee.

        The risk that a mortgaged property may be, or become,  contaminated with
hazardous  materials is greater with respect to commercial  and mixed-use  loans
than with  respect  to  residential  mortgage  loans.  Under the laws of certain
states, contamination of a property may

                                       13



give rise to a lien on the  property to assure the costs of cleanup.  In several
states,  such a lien has priority over the lien of an existing  mortgage against
such property. In addition,  under the laws of some states and under the federal
Comprehensive  Environmental  Response,  Compensation  and Liability Act of 1980
("CERCLA"),  a lender may be liable,  as an "owner" or "operator,"  for costs of
addressing releases or threatened releases of hazardous  substances that require
remedy  at a  property,  if  agents  or  employees  of the  lender  have  become
sufficiently  involved in the operations of the borrower,  regardless of whether
or not the  environmental  damage or threat  was  caused by a prior  owner.  See
"Certain Legal Aspects of the Mortgage Loans -- Environmental Considerations." A
lender also risks such liability on  foreclosure of the mortgage.  Any such lien
arising with respect to a mortgaged property would adversely affect the value of
that mortgaged  property and could make  impracticable  the  foreclosure on that
mortgaged  property  in the  event of a  default  by the  related  borrower.  In
addition,  certain  environmental laws impose liability for releases of asbestos
into the air.  Third  parties may seek recovery from owners or operators of real
property for personal injury  associated with exposure to asbestos,  lead paint,
radon or other  hazardous  substances.  Property  owners in some areas have been
subject to liability claims associated with mold.

CONTRACTS

        GENERAL

        To the extent provided in the prospectus supplement,  each contract will
be secured by a security interest in a new or used  manufactured  home, called a
Manufactured  Home. The contracts may include  contracts that are FHA loans. The
method of computing the  Loan-to-Value  Ratio of a contract will be described in
the prospectus supplement.

        CONTRACT INFORMATION IN PROSPECTUS SUPPLEMENTS

        Each  prospectus  supplement  relating to an issuing entity whose assets
include a substantial  proportion of contracts will contain certain information,
as of the dates specified in that  prospectus  supplement and to the extent then
applicable  and  specifically  known  to  the  depositor,  with  respect  to any
contracts, including:

        o   the total outstanding  principal  balance and the largest,  smallest
            and average outstanding principal balance of the contracts as of the
            applicable cut-off date;

        o   whether  the  manufactured   homes  were  new  or  used  as  of  the
            origination of the related contracts;

        o   information  regarding  the  prepayment  provisions,  if any, of the
            contracts;

                                       14



        o   for contracts with  adjustable  contract  rates,  referred to as ARM
            contracts, the index, the frequency of the adjustment dates, and the
            maximum  contract rate or monthly  payment  variation at the time of
            any adjustment thereof and over the life of the ARM contract;

        o   the number of contracts  that are  delinquent and the number of days

depositor at the time the Notes or  Certificates,  as applicable,  are initially
offered, more general information of the nature described above will be provided
in the prospectus  supplement,  and specific  information will be set forth in a
report  that  will  be  available  to   purchasers   of  the  related  Notes  or
Certificates,  as applicable, at or before the initial issuance thereof and will
be filed as part of a  Current  Report  on Form 8-K with the  Commission  within
fifteen days after the related  initial  issuance.  The  characteristics  of the
contracts  included in an issuing entity will not vary by more than five percent
(by total  principal  balance as of the cut-off  date) from the  characteristics
thereof that are described in the prospectus supplement.

        The  information  described  above regarding the contracts in an issuing
entity may be presented in the prospectus supplement in combination with similar
information regarding the mortgage loans in the issuing entity.

        PAYMENT PROVISIONS OF THE CONTRACTS

        All of the contracts will provide for payments of principal, interest or
both, on due dates that occur monthly or at some other  interval as is specified
in the prospectus  supplement or for payments in another manner described in the
prospectus  supplement.  Each contract may provide for no accrual of interest or
for accrual of interest  thereon at a contract  rate that is fixed over its term
or that adjusts from time to time, or as otherwise  specified in the  prospectus
supplement.  Each  contract  may provide for  scheduled  payments to maturity or
payments  that adjust from time to time to  accommodate  changes in the contract
rate as otherwise described in the prospectus supplement.

AGENCY SECURITIES

        The Agency  Securities  will  consist of any  combination  of Ginnie Mae
certificates,  Fannie Mae certificates and Freddie Mac  certificates,  which may
include Stripped Agency Securities, as described below.

        GINNIE MAE

        Ginnie Mae is a  wholly-owned  corporate  instrumentality  of the United
States within the Department of Housing and Urban Development. Section 306(g) of
Title III of the  Housing  Act  authorizes  Ginnie Mae to  guarantee  the timely
payment of the principal of and interest on  certificates  that are based on and
backed  by a  pool  of FHA  loans,  VA  loans  or by  pools  of  other  eligible
residential loans.

        Section  306(g) of the  Housing  Act  provides  that "the full faith and
credit of the United States is pledged to the payment of all amounts that may be
required to be paid under any


                                       15



guaranty under this  subsection." To meet its  obligations  under that guaranty,
Ginnie Mae is authorized,  under Section  306(d) of the National  Housing Act of
1934 (the  "Housing  Act"),  to borrow from the United  States  Treasury with no
limitations as to amount, to perform its obligations under its guarantee.

        GINNIE MAE CERTIFICATES

        Each  Ginnie Mae  certificate  will be a "fully  modified  pass-through"
mortgage-backed  certificate issued and serviced by an issuer approved by Ginnie
Mae or Fannie  Mae as a  seller-servicer  of FHA  loans or VA  loans,  except as
described below regarding  Stripped  Agency  Securities (as defined below).  The
loans underlying  Ginnie Mae certificates may consist of FHA loans, VA loans and
other  loans  eligible  for  inclusion  in  loan  pools  underlying  Ginnie  Mae
certificates.  The mortgage loans may be secured by Manufactured  Homes,  Single
Family Property or Multifamily  Property.  Ginnie Mae certificates may be issued
under  either or both of the Ginnie Mae I program and the Ginnie Mae II program,
as described in the prospectus supplement. If the issuing entity includes Ginnie
Mae  certificates,   your  prospectus   supplement  will  include  any  material
additional   information   regarding  the  Ginnie  Mae  guaranty  program,   the
characteristics  of the pool  underlying  those  Ginnie  Mae  certificates,  the
servicing of the related  pool,  the payment of principal and interest on Ginnie
Mae  certificates   and  other  relevant   matters   regarding  the  Ginnie  Mae
certificates.

        Except  as  otherwise  specified  in  the  prospectus  supplement  or as
described  below with  respect to Stripped  Agency  Securities,  each Ginnie Mae
certificate will provide for the payment,  by or on behalf of the issuer, to the
registered  holder  of that  Ginnie  Mae  certificate  of  monthly  payments  of
principal and interest equal to the holder's proportionate interest in the total
amount of the monthly  principal and interest  payments on each related FHA loan
or VA loan,  minus  servicing  and  guaranty  fees  totaling  the  excess of the
interest on that FHA loan or VA loan over the Ginnie Mae certificates'  interest
rate.  In addition,  each payment to a holder of a Ginnie Mae  certificate  will
include proportionate pass-through payments to that holder of any prepayments of
principal of the FHA loans or VA loans underlying the Ginnie Mae certificate and
the holder's  proportionate  interest in the remaining  principal balance in the
event of a foreclosure or other disposition of any related FHA loan or VA loan.

        The  Ginnie  Mae  certificates  do not  constitute  a  liability  of, or
evidence any recourse against,  the issuer of the Ginnie Mae  certificates,  the
depositor  or any  affiliates  of the  depositor,  and the  only  recourse  of a
registered  holder (for  example,  the  trustee)  is to enforce the  guaranty of
Ginnie Mae.

        Ginnie Mae will have  approved  the  issuance  of each of the Ginnie Mae
certificates  included  in an  issuing  entity  in  accordance  with a  guaranty
agreement  or  contract  between  Ginnie  Mae and the  issuer of the  Ginnie Mae
certificates.  Pursuant  to that  agreement,  that  issuer,  in its  capacity as
servicer,  is required to perform customary functions of a servicer of FHA loans
and VA loans,  including  collecting payments from borrowers and remitting those
collections  to  the  registered  holder,  maintaining  escrow  and  impoundment
accounts of borrowers for payments of taxes,  insurance and other items required
to be paid by the borrower,  maintaining primary hazard insurance, and advancing
from its own funds to make timely  payments of all amounts due on the Ginnie Mae
certificate,  even if the payments  received by that issuer on the loans backing
the Ginnie  Mae  certificate  are less than the  amounts  due.  If the issuer is
unable to make payments on a Ginnie Mae  certificate as they become due, it must
promptly  notify Ginnie Mae and request  Ginnie Mae to make that  payment.  Upon
that  notification and request,  Ginnie Mae will make those payments directly to
the registered holder of the Ginnie Mae certificate.  In the event no payment is
made by the issuer and the issuer fails to notify and request Ginnie Mae to make
that payment,  the registered  holder of the Ginnie Mae certificate has recourse
against only Ginnie Mae to obtain that payment.  The trustee or its nominee,  as
registered holder of the Ginnie Mae certificates

                                       16



included in an issuing entity,  is entitled to proceed  directly  against Ginnie
Mae under the terms of the guaranty agreement or contract relating to the Ginnie
Mae  certificates for any amounts that are unpaid when due under each Ginnie Mae
certificate.

        The Ginnie Mae certificates included in an issuing entity may have other
characteristics  and terms,  different from those described above so long as the
Ginnie Mae  certificates and underlying  residential  loans meet the criteria of
the  rating  agency or  agencies.  The Ginnie Mae  certificates  and  underlying
residential loans will be described in the prospectus supplement.

        FANNIE MAE

        Fannie Mae is a federally  chartered and  stockholder-owned  corporation
organized and existing under the Federal National Mortgage  Association  Charter
Act, as amended (the "Charter  Act").  Fannie Mae was originally  established in
1938 as a United States government agency to provide  supplemental  liquidity to
the mortgage market and was transformed into a  stockholder-owned  and privately
managed corporation by legislation enacted in 1968.

        Fannie Mae provides funds to the mortgage market by purchasing  mortgage
loans  from  lenders.  Fannie Mae  acquires  funds to  purchase  loans from many
capital market investors, thus expanding the total amount of funds available for
housing.  Operating nationwide,  Fannie Mae helps to redistribute mortgage funds
from  capital-surplus  to  capital-short  areas. In addition,  Fannie Mae issues
mortgage-backed  securities  primarily in exchange  for pools of mortgage  loans
from  lenders.  Fannie Mae receives  fees for its guaranty of timely  payment of
principal and interest on its mortgage-backed securities.

        FANNIE MAE CERTIFICATES

        Fannie   Mae   certificates   are   Guaranteed   Mortgage   Pass-Through
Certificates  typically  issued  pursuant to a prospectus  that is  periodically
revised by Fannie Mae. Fannie Mae certificates  represent  fractional  undivided
interests in a pool of mortgage  loans formed by Fannie Mae.  Each mortgage loan
must meet the applicable standards of the Fannie Mae purchase program.  Mortgage
loans comprising a pool are either provided by Fannie Mae from its own portfolio
or  purchased  pursuant  to the  criteria  of the Fannie Mae  purchase  program.
Mortgage loans underlying Fannie Mae certificates  included in an issuing entity
will consist of conventional mortgage loans secured by Single Family Property or
Multifamily  Property,  FHA loans,  or VA loans.  If the issuing entity includes
Fannie Mae  certificates,  your prospectus  supplement will include any material
additional  information regarding the Fannie Mae program, the characteristics of
the pool  underlying the Fannie Mae  certificates,  the servicing of the related
pool, payment of principal and interest on the Fannie Mae certificates and other
relevant matters about the Fannie Mae certificates.

        Except as described  below with respect to Stripped  Agency  Securities,
Fannie Mae guarantees to each registered holder of a Fannie Mae certificate that
it will distribute  amounts  representing that holder's  proportionate  share of
scheduled principal and interest at the applicable interest rate provided for by
that Fannie Mae  certificate on the underlying  mortgage  loans,  whether or not
received,  and that holder's proportionate share of the full principal amount of
any prepayment or foreclosed or other finally liquidated  mortgage loan, whether
or not the related principal amount is actually recovered.

        The  obligations  of Fannie  Mae under its  guarantees  are  obligations
solely of Fannie Mae and are not backed by, nor  entitled to, the full faith and
credit  of the  United  States.  If Fannie  Mae were  unable  to  satisfy  those
obligations,  distributions  to the  holders  of Fannie Mae  certificates  would
consist  solely of payments and other  recoveries on the  underlying  loans and,
accordingly,

                                       17



monthly  distributions  to the  holders  of  Fannie  Mae  certificates  would be
affected by delinquent payments and defaults on those loans.

        Fannie Mae certificates  evidencing interests in pools of mortgage loans
formed on or after May 1, 1985  (other than  Fannie Mae  certificates  backed by
pools  containing  graduated  payment  mortgage loans or multifamily  loans) are
available  in  book-entry  form  only.  For a Fannie Mae  certificate  issued in
book-entry  form,  distributions  on the Fannie Mae certificate  will be made by
wire, and for a fully registered Fannie Mae certificate,  distributions  will be
made by check.

        The Fannie Mae certificates included in an issuing entity may have other
characteristics and terms,  different from those described above, as long as the
Fannie Mae certificates  and underlying  mortgage loans meet the criteria of the
rating agency or agencies rating the  Certificates.  The Fannie Mae certificates
and underlying mortgage loans will be described in the prospectus supplement.

        FREDDIE MAC

        Freddie Mac is a corporate  instrumentality of the United States created
pursuant to Title III of the Emergency Home Finance Act of 1970, as amended (the
"Freddie Mac Act").  Freddie Mac was  established  primarily  for the purpose of
increasing  the  availability  of mortgage  credit for the  financing  of needed
housing.  It seeks to provide an enhanced  degree of liquidity  for  residential
mortgage  investments  primarily by assisting  in the  development  of secondary
markets  for  conventional  mortgages.  The  principal  activity  of Freddie Mac
currently  consists  of the  purchase of first  lien,  conventional  residential
mortgage loans or participation interests in those mortgage loans and the resale
of the mortgage loans so purchased in the form of mortgage securities, primarily
Freddie Mac  certificates.  Freddie Mac is  confined  to  purchasing,  so far as
practicable,  mortgage loans and participation interests in mortgage loans which
it deems to be of the quality,  type and class as to meet generally the purchase
standards imposed by private institutional mortgage investors.

        FREDDIE MAC CERTIFICATES

        Each Freddie Mac certificate  represents an undivided interest in a pool
of  residential  loans that may consist of first lien  conventional  residential
loans,  FHA loans or VA loans (the  "Freddie Mac  Certificate  Group").  Each of
these mortgage loans must meet the applicable standards set forth in the Freddie
Mac Act. A Freddie Mac Certificate Group may include whole loans,  participation
interests  in  whole  loans  and  undivided  interests  in  whole  loans  and/or
participations  comprising another Freddie Mac Certificate Group. If the issuing
entity  includes  Freddie Mac  certificates,  your  prospectus  supplement  will
include any material additional  information  regarding the Freddie Mac guaranty
program,   the   characteristics   of  the  pool  underlying  that  Freddie  Mac
certificate,  the  servicing  of the  related  pool,  payment of  principal  and
interest on the Freddie Mac certificate and any other relevant matters about the
Freddie Mac certificates.

        Except as described  below with respect to Stripped  Agency  Securities,
Freddie Mac guarantees to each  registered  holder of a Freddie Mac  certificate
the timely payment of interest on the underlying mortgage loans to the extent of
the applicable  interest rate on the  registered  holder's pro rata share of the
unpaid  principal  balance  outstanding on the underlying  mortgage loans in the
Freddie Mac  Certificate  Group  represented  by that  Freddie Mac  certificate,
whether or not received.  Freddie Mac also guarantees to each registered  holder
of a Freddie Mac  certificate  collection by that holder of all principal on the
underlying  mortgage  loans,  without any offset or deduction,  to the extent of
that holder's pro rata share of the  principal,  but does not,  except if and to
the extent specified in the prospectus supplement,  guarantee the timely payment
of scheduled principal. Pursuant to its guarantees,  Freddie Mac also guarantees
ultimate collection of scheduled  principal  payments,  prepayments of principal
and the  remaining  principal  balance  in the

                                       18



event of a foreclosure or other disposition of a mortgage loan.  Freddie Mac may
remit the amount due on account of its  guarantee of  collection of principal at
any time after default on an  underlying  mortgage  loan,  but not later than 30
days following the latest of

                (1)     foreclosure sale;

                (2)     payment of the claim by any mortgage insurer; and

                (3)     the  expiration of any right of  redemption,  but in any
                event no later than one year after demand has been made upon the
                borrower for accelerated payment of principal.

        In taking actions regarding the collection of principal after default on
the mortgage loans underlying Freddie Mac certificates,  including the timing of
demand  for  acceleration,  Freddie  Mac  reserves  the  right to  exercise  its
servicing  judgment  for the  mortgage  loans in the same manner as for mortgage
loans  that it has  purchased  but not sold.  The length of time  necessary  for
Freddie Mac to determine that a mortgage loan should be accelerated  varies with
the particular  circumstances of each borrower,  and Freddie Mac has not adopted
servicing  standards  that require that the demand be made within any  specified
period.

        Freddie Mac  certificates  are not guaranteed by the United States or by
any Federal Home Loan Bank and do not  constitute  debts or  obligations  of the
United  States or any Federal  Home Loan Bank.  The  obligations  of Freddie Mac
under its guarantee are obligations solely of Freddie Mac and are not backed by,
nor entitled to, the full faith and credit of the United States.  If Freddie Mac
were unable to satisfy those  obligations,  distributions  to holders of Freddie
Mac  certificates  would consist solely of payments and other  recoveries on the
underlying mortgage loans and, accordingly,  monthly distributions to holders of
Freddie Mac certificates  would be affected by delinquent  payments and defaults
on those mortgage loans.

        The Freddie  Mac  certificates  included  in an issuing  entity may have
other  characteristics and terms,  different from those described above, so long
as the Freddie Mac certificates and underlying  mortgage loans meet the criteria
of  the  rating  agency  or  agencies  rating  the  Notes  or  Certificates,  as
applicable.  The Freddie Mac certificates and underlying  mortgage loans will be
described in the prospectus supplement.

        STRIPPED AGENCY SECURITIES

        The Ginnie Mae  certificates,  Fannie Mae  certificates  or Freddie  Mac
certificates  may be  issued  in the  form  of  certificates  ("Stripped  Agency
Securities")  that represent an undivided  interest in all or part of either the
principal  distributions  (but not the interest  distributions)  or the interest
distributions  (but  not the  principal  distributions),  or in  some  specified
portion  of the  principal  or  interest  distributions  (but  not all of  those
distributions),  on an  underlying  pool of mortgage  loans or other  Ginnie Mae
certificates,  Fannie Mae certificates or Freddie Mac certificates.  Ginnie Mae,
Fannie Mae or Freddie Mac, as applicable,  will  guarantee each Stripped  Agency
Security to the same extent as that entity guarantees the underlying  securities
backing the Stripped  Agency  Securities or to the extent  described above for a
Stripped Agency Security  backed by a pool of mortgage loans,  unless  otherwise
specified in the prospectus supplement.  If the issuing entity includes Stripped
Agency  Securities,   your  prospectus  supplement  will  include  any  material
additional  information  regarding the  characteristics of the assets underlying
the Stripped  Agency  Securities,  the payments of principal and interest on the
Stripped Agency  Securities and other relevant matters about the Stripped Agency
Securities.

                                       19



MORTGAGE SECURITIES

        The Mortgage Securities will represent  beneficial interests in loans of
the type that would otherwise be eligible to be mortgage  loans,  unsecured home
improvement loans, contract or Agency Securities, or collateralized  obligations
secured by mortgage loans,  unsecured home improvement loans, contract or Agency
Securities. Although individual Underlying Loans may be insured or guaranteed by
the United States or an agency or  instrumentality  of the United  States,  they
need not be,  and  Mortgage  Securities  themselves  will not be so  insured  or
guaranteed. Except as otherwise set forth in the prospectus supplement, Mortgage
Securities  will generally be similar to Notes or  Certificates,  as applicable,
offered under this prospectus.

        The  depositor  will  register  the  offering of the  relevant  Mortgage
Securities  as a  primary  offering  of such  securities,  unless  the  Mortgage
Securities are themselves exempt from registration under the Securities Act. The
offering of Mortgage  Securities included in a trust fund will not be separately
registered if all of the following are true:

                (1)     neither the issuer of the Mortgage Securities nor any of
        its  affiliates  has  a  direct  or  indirect  agreement,   arrangement,
        relationship  or  understanding,  written or otherwise,  relating to the
        Mortgage Securities and the related trust fund;

                (2)     neither the issuer of the Mortgage Securities nor any of
        its affiliates is an affiliate of the depositor, sponsor, issuing entity
        or any underwriter relating to such trust fund and series of securities;
        and

                (3)     the  depositor  would  be free to  publicly  resell  the
        Mortgage Securities without registration under the Securities Act.

        If all the conditions for the Mortgage  Securities  described  above are
not met,  the  offering  of the  relevant  Mortgage  Securities  itself  will be
registered as a primary offering of such securities under the Securities Act.

        The prospectus supplement for the Notes or Certificates,  as applicable,
of each series  evidencing  interests in an issuing  entity  including  Mortgage
Securities will include a description of the Mortgage Securities and any related
credit enhancement,  and the related mortgage loans,  unsecured home improvement
loans, contracts, or Agency Securities will be described together with any other
mortgage  loans or Agency  Securities  included  in the  issuing  entity of that
series.  As used in this prospectus,  the terms "mortgage loans," unsecured home
improvement  loans,  contracts,  include  the  mortgage  loans,  unsecured  home
improvement loans, contracts, as applicable,  underlying the Mortgage Securities
in your issuing entity. References in this prospectus to advances to be made and
other actions to be taken by the master  servicer in connection  with the Assets
may include any advances made and other  actions taken  pursuant to the terms of
the applicable Mortgage Securities.

FHA LOANS AND VA LOANS

        FHA loans  will be insured by the FHA as  authorized  under the  Housing
Act, and the United States Housing Act of 1937, as amended.  One- to four-family
FHA loans will be insured under various FHA programs  including the standard FHA
203-b programs to finance the  acquisition of one- to four-family  housing units
and the FHA 245 graduated  payment  mortgage  program.  The FHA loans  generally
require a minimum down  payment of  approximately  5% of the original  principal
amount  of the FHA  loan.  No FHA  loan may have an  interest  rate or  original
principal balance exceeding the applicable FHA limits at the time of origination
of that FHA loan.

                                       20



        Mortgage loans,  unsecured home improvement loans,  contracts,  that are
FHA loans are insured by the FHA (as described in the prospectus supplement,  up
to an amount equal to 90% of the sum of the unpaid  principal of the FHA loan, a
portion of the unpaid interest and other liquidation  costs) pursuant to Title I
of the Housing Act.

        There are two primary FHA  insurance  programs  that are  available  for
multifamily loans. Sections 221(d)(3) and (d)(4) of the Housing Act allow HUD to
insure multifamily loans that are secured by newly constructed and substantially
rehabilitated  multifamily  rental  projects.  Section  244 of the  Housing  Act
provides  for  co-insurance  of those loans made under  Sections  221(d)(3)  and
(d)(4) by HUD/FHA and a HUD-approved co-insurer. Generally the term of this type
of  multifamily  loan may be up to 40 years and the ratio of the loan  amount to
property replacement cost can be up to 90%.

        Section 223(f) of the Housing Act allows HUD to insure multifamily loans
made for the purchase or refinancing of existing  apartment projects that are at
least three years old.  Section 244 also provides for  co-insurance  of mortgage
loans made under Section 223(f).  Under Section 223(f), the loan proceeds cannot
be used for substantial  rehabilitation work, but repairs may be made for up to,
in general,  the greater of 15% of the value of the project and a dollar  amount
per  apartment  unit  established  from time to time by HUD. In general the loan
term may not exceed 35 years and a loan-to-value ratio refinancing of a project.

        VA loans will be partially  guaranteed by the VA under the  Servicemen's
Readjustment Act of 1944, as amended (the "Servicemen's  Readjustment Act"). The
Servicemen's Readjustment Act permits a veteran (or in some instances the spouse
of a veteran) to obtain a mortgage  loan  guarantee by the VA covering  mortgage
financing of the  purchase of a one- to  four-family  dwelling  unit at interest
rates permitted by the VA. The program has no mortgage loan limits,  requires no
down payment from the  purchasers and permits the guarantee of mortgage loans of
up to 30 years' duration.  However,  no VA loan will have an original  principal
amount  greater than five times the partial VA guarantee  for that VA loan.  The
maximum  guarantee  that may be issued by the VA under this  program will be set
forth in the prospectus supplement.

PRE-FUNDING ACCOUNTS

        To the extent  provided  in a  prospectus  supplement,  a portion of the
proceeds  of the  issuance  of  Notes or  Certificates,  as  applicable,  may be
deposited into an account maintained with the trustee (a "Pre-Funding Account").
In that case, the depositor will be obligated to sell at a predetermined price -
and the  issuing  entity for the  related  series of Notes or  Certificates,  as
applicable,  will be obligated to purchase - additional  Assets (the "Subsequent
Assets") from time to time,  and as frequently as daily,  within the period (not
to exceed three months) specified in the prospectus supplement (the "Pre-Funding
Period") after the issuance of the Notes or Certificates,  as applicable, having
a total principal  balance  approximately  equal to the amount on deposit in the
Pre-Funding Account (the "Pre-Funded Amount") for that series on the date of its
issuance. The Pre-Funded Amount for a series will be specified in the prospectus
supplement,  and will not in any case exceed 50% of the proceeds of the offering
of the related Notes or Certificates,  as applicable. Any Subsequent Assets will
be required to satisfy specific eligibility criteria more fully set forth in the
prospectus  supplement,  which criteria will be consistent  with the eligibility
criteria of the Assets  initially  included in the  issuing  entity,  subject to
those  exceptions  that are expressly  stated in the prospectus  supplement.  In
addition, specific conditions must be satisfied before the Subsequent Assets are
transferred  into the issuing  entity,  for example,  the delivery to the rating
agencies  and to the trustee of any  required  opinions  of counsel.  See "ERISA
Considerations--Pre-Funding   Accounts"  for  additional  information  regarding
Pre-Funding Accounts.

        Except as set forth in the following  sentence,  the  Pre-Funded  Amount
will be used  only to  purchase  Subsequent  Assets.  The  related  pooling  and
servicing  agreement or other agreement

                                       21



providing for the transfer of Subsequent  Assets will generally provide that the
transfers  must be made within up to three months (with respect to any series of
Notes or Certificates) or up to, but not in excess of, one year (with respect to
any  series of Notes or  Certificates)  after  the  Closing  Date,  and that any
portion of the Pre-Funded Amount remaining in the Pre-Funding Account at the end
of the Pre-Funding Period will be used to prepay one or more classes of Notes or
Certificates,  as applicable,  in the amounts and in the manner specified in the
prospectus  supplement.  In addition, if specified in the prospectus supplement,
the depositor may be required to deposit cash into an account  maintained by the
trustee (the  "Capitalized  Interest  Account")  for the purpose of assuring the
availability  of  funds  to  pay  interest  on the  Notes  or  Certificates,  as
applicable,   during  the  Pre-Funding  Period.  Any  amount  remaining  in  the
Capitalized  Interest  Account  at the  end of the  Pre-Funding  Period  will be
remitted as specified in the prospectus supplement.

        Amounts  deposited in the Pre-Funding and Capitalized  Interest Accounts
will  be  permitted  to be  invested,  pending  application,  only  in  eligible
investments authorized by each applicable rating agency.

ACCOUNTS

        Each issuing entity will include one or more accounts,  established  and
maintained  on behalf of the  securityholders  into  which the person or persons
designated in the prospectus  supplement  will, to the extent  described in this
prospectus and in the prospectus supplement deposit all payments and collections
received or advanced  with respect to the Assets and other assets in the issuing
entity.  This type of account  may be  maintained  as an  interest  bearing or a
non-interest bearing account, and funds held in that account may be held as cash
or invested in some short-term,  investment grade  obligations,  in each case as
described   in   the   prospectus   supplement.    See   "Description   of   the
Agreements--Material   Terms  of  the  Pooling  and  Servicing   Agreements  and
Underlying Servicing  Agreements--Collection Account and Related Accounts." Such
accounts will be  established  so as to comply with the standards of each Rating
Agency  that has rated any one or more  classes  of  securities  of the  related
series.  Such accounts shall be maintained as Eligible  Accounts,  and the funds
held  therein  may be held as cash or  invested in  Permitted  Investments.  The
person  designated in the  prospectus  supplement  will have sole  discretion to
determine  the  particular  investments  made so long as it  complies  with  the
investment  terms of the related pooling and servicing  agreement or the related
servicing agreement and indenture. Any Permitted Investments shall not cause the
depositor to register under the Investment  Company Act of 1940. Any interest or
other income earned on funds in such accounts will be paid to the related master
servicer or trustee as additional compensation or will be available for payments
on the securities as provided in the prospectus supplement.  If permitted by the
Rating Agency or Agencies and so specified in the related prospectus supplement,
such accounts may contain funds relating to more than one series of Certificates
and may contain  other funds  representing  payments on  mortgages  owned by the
related master servicer or serviced by it on behalf of others.

CREDIT SUPPORT

        If so provided in the prospectus supplement,  partial or full protection
against some defaults and losses on the Assets in the related issuing entity may
only be provided to one or more classes of Notes or Certificates, as applicable,
in the related series in the form of  subordination of one or more other classes
of Notes or  Certificates,  as  applicable,  in that series or by one or more of
only the  following  types of  credit  support:  a letter of  credit,  insurance
policy,  guarantee,  reserve fund, or a combination of these (any of these types
of coverage for the Notes or  Certificates,  as  applicable,  of any series,  is
referred to  generally as "credit  support").  The amount and types of coverage,
the  identification  of the entity  providing the coverage (if  applicable)  and
related  information for each type of credit support,  if any, will be described
in  the  prospectus  supplement  for a  series  of  Notes  or  Certificates,  as
applicable. See "Description of Credit Support."

                                       22



CASH FLOW AGREEMENTS

        The trust fund may include one or more derivative  instruments,  (each a
"Cash Flow Agreement"),  as described in this section.  All Cash Flow Agreements
included in any trust fund will be used only in a manner that  reduces or alters
risk  resulting from the mortgage loans or other assets in the pool, and only in
a manner such that the return on the offered  securities will be based primarily
on the  performance of the mortgage loans or other assets in the pool. Cash Flow
Agreements may include only 1) interest rate swaps (or caps, floors and collars)
and yield  supplement  agreements as described  below, 2) currency swaps, and 3)
market  value  swaps  that  are  referenced  to the  value of one or more of the
mortgage  loans or other  assets  included  in the  trust  fund or to a class of
offered securities.

        An interest rate swap is an agreement  between two parties to exchange a
stream of interest  payments on an agreed  hypothetical or "notional"  principal
amount.  No  principal  amount is  exchanged  between the  counterparties  to an
interest rate swap. In a typical swap, one party agrees to pay a fixed rate on a
notional principal amount,  while the counterparty pays a floating rate based on
one or more reference  interest  rates  including the London  Interbank  Offered
Rate,  or LIBOR,  a specified  bank's  prime rate or U.S.  Treasury  Bill rates.
Interest  rate swaps also  permit  counterparties  to  exchange a floating  rate
obligation based upon one reference interest rate, such as LIBOR, for a floating
rate  obligation  based upon  another  referenced  interest  rate,  such as U.S.
Treasury Bill rates. An interest rate cap, collar or floor is an agreement where
the  counterparty  agrees to make payments  representing  interest on a notional
principal  amount when a  specified  reference  interest  rate is above a strike
rate, outside of a range of strike rates, or below a strike rate as specified in
the agreement, generally in exchange for a fixed amount paid to the counterparty
at the time the  agreement is entered  into. A yield  supplement  agreement is a
type of cap  agreement,  and is  substantially  similar  to a cap  agreement  as
described above.

        The  trustee  on behalf of a trust  fund may enter  into  interest  rate
swaps, caps, floors and collars, or yield supplement agreements, to minimize the
risk to  securityholders  from adverse  changes in interest  rates or to provide
supplemental credit support. Cap agreements and yield supplement  agreements may
be entered into to supplement the interest rate or other rates available to make
interest payments on one or more classes of the securities of any series.

        A market value swap might be used in a structure where the pooled assets
are hybrid ARMs, or mortgage loans that provide for a fixed rate period and then
convert by their terms to adjustable rate loans.  Such a structure might provide
that at a specified  date near the end of the fixed rate period,  the  investors
must  tender  their  securities  to the  trustee  who  will  then  transfer  the
securities to other investors in a mandatory auction procedure. The market value
swap would ensure that the original  investors would receive at least par at the
time of tender,  by covering  any  shortfall  between  par and the then  current
market value of their securities.

        Any Cash Flow  Agreements  will be  documented  based upon the  standard
forms provided by the International Swaps and Derivatives Association,  or ISDA.
These forms  generally  consist of an ISDA master  agreement,  a schedule to the
master  agreement,  and a confirmation,  although in some cases the schedule and
confirmation  will be combined in a single document and the standard ISDA master
agreement will be incorporated  therein by reference.  Standard ISDA definitions
also will be  incorporated  by  reference.  Each  confirmation  will provide for
payments to be made by the Cash Flow Agreement counterparty to the trust, and in
some cases by the trust to the Cash Flow Agreement counterparty, generally based
upon specified notional amounts and upon differences  between specified interest
rates  or  values.  For  example,  the  confirmation  for an  interest  rate cap
agreement will contain a schedule of fixed interest rates, generally referred to
as strike rates, and a schedule of notional amounts,  for each distribution date
during the term of the interest rate cap agreement.  The confirmation  also will
specify a reference rate,  generally a floating or adjustable interest rate, and
will provide that payments will be made by the Cash Flow

                                       23



Agreement  counterparty  to the trust on each  distribution  date,  based on the
notional  amount  for that  distribution  date and the  excess,  if any,  of the
specified reference rate over the strike rate for that distribution date.

        In the  event of the  withdrawal  of the  credit  rating  of a Cash Flow
Agreement  counterparty  or the  downgrade  of such credit  rating  below levels
specified in the Cash Flow Agreement  (where the Cash Flow Agreement is relevant
to the ratings of the offered  securities,  such levels generally are set by the
rating  agencies  rating  the  offered  securities),  the  Cash  Flow  Agreement
counterparty  may be  required to post  collateral  for the  performance  of its
obligations  under the Cash Flow  Agreement,  or to take certain other  measures
intended to assure performance of those obligations.  Posting of collateral will
be documented using the ISDA Credit Support Annex.

        There can be no  assurance  that the trustee  will be able to enter into
Cash Flow  Agreements  at any specific  time or at prices or on other terms that
are  advantageous.  In addition,  although the terms of the Cash Flow Agreements
may  provide  for  termination  under  various  circumstances,  there  can be no
assurance  that the trustee will be able to terminate a Cash Flow Agreement when
it would be economically advantageous to the trust fund to do so.

                                 USE OF PROCEEDS

        The  net  proceeds  to be  received  from  the  sale  of  the  Notes  or
Certificates, as applicable, will be applied by the depositor to the purchase of
Assets, or the repayment of the financing incurred in that purchase,  and to pay
for some of the expenses incurred in connection with that purchase of Assets and
sale of Notes or Certificates,  as applicable. The depositor expects to sell the
Notes or  Certificates,  as  applicable,  from time to time,  but the timing and
amount of offerings of Notes or  Certificates,  as applicable,  will depend on a
number of factors,  including  the volume of Assets  acquired by the  depositor,
prevailing interest rates, availability of funds and general market conditions.

                              YIELD CONSIDERATIONS

GENERAL

        The yield on any Offered  Security  will depend on the price paid by the
securityholder,  the Interest  Rate of the  Security,  the receipt and timing of
receipt of  distributions  on the Security and the weighted  average life of the
Assets in the related  issuing  entity  (which may be  affected by  prepayments,
defaults, liquidations or repurchases).

INTEREST RATE

        Notes or Certificates,  as applicable,  of any class within a series may
have fixed, variable or adjustable Interest Rates, which may or may not be based
upon the interest rates borne by the Assets in the related issuing  entity.  The
prospectus  supplement  for any series will specify the  Interest  Rate for each
class of Notes or Certificates,  as applicable, or, in the case of a variable or
adjustable  Interest  Rate,  the method of  determining  the Interest  Rate; the
effect,  if any, of the  prepayment  of any Asset on the Interest Rate of one or
more  classes  of  Notes  or  Certificates,   as  applicable;  and  whether  the
distributions  of interest on the Notes or Certificates,  as applicable,  of any
class will be dependent, in whole or in part, on the performance of any borrower
under a Cash Flow Agreement.

        If  specified  in the  prospectus  supplement,  the  effective  yield to
maturity to each holder of Notes or  Certificates,  as  applicable,  entitled to
payments of interest  will be below that  otherwise  produced by the  applicable
Interest Rate and purchase price of that Security because, while

                                       24



interest may accrue on each Asset during a period (each,  an "Accrual  Period"),
the  distribution  of that  interest  will be made on a day that may be  several
days, weeks or months following the period of accrual.

TIMING OF PAYMENT OF INTEREST

        Each payment of interest on the Notes or  Certificates,  as  applicable,
entitled to  distributions of interest (or addition to the Security Balance of a
class of Accrual  Securities)  will be made by or on behalf of the trustee  each
month on the date specified in the related  prospectus  supplement (each date, a
"Distribution  Date"),  and will  include  interest  accrued  during the Accrual
Period for that Distribution  Date. As indicated above under "--Interest  Rate,"
if the Accrual  Period  ends on a date other than the day before a  Distribution
Date for the related series, the yield realized by the holders of those Notes or
Certificates,  as  applicable,  may be lower than the yield that would result if
the Accrual Period ended on the day before the Distribution Date.

PAYMENTS OF PRINCIPAL; PREPAYMENTS

        The yield to maturity on the Notes or Certificates,  as applicable, will
be affected by the rate of principal  payments on the Assets (or, in the case of
Mortgage Securities and Agency Securities,  the underlying assets related to the
Mortgage  Securities and Agency  Securities),  including  principal  prepayments
resulting  from both  voluntary  prepayments  by the borrowers  and  involuntary
liquidations.  The rate at which principal prepayments occur will be affected by
a variety of  factors,  including  the terms of the Assets  (or,  in the case of
Mortgage Securities and Agency Securities,  the underlying assets related to the
Mortgage  Securities and Agency  Securities),  the level of prevailing  interest
rates,   the   availability  of  mortgage  credit  and  economic,   demographic,
geographic, tax, legal and other factors.

        In general,  however,  if prevailing  interest rates fall  significantly
below the interest  rates on the Assets in a particular  issuing  entity (or, in
the case of Mortgage  Securities and Agency  Securities,  the underlying  assets
related to the  Mortgage  Securities  and Agency  Securities),  those assets are
likely to be the  subject of higher  principal  prepayments  than if  prevailing
rates remain at or above the rates borne by those  assets.  However,  you should
note that  some  Assets  (or,  in the case of  Mortgage  Securities  and  Agency
Securities,  the underlying assets related to the Mortgage Securities and Agency
Securities)  may consist of loans with  different  interest  rates.  The rate of
principal payment on Mortgage Securities will also be affected by the allocation
of principal payments on the underlying assets among the Mortgage  Securities or
Agency Securities and other Mortgage Securities or Agency Securities of the same
series.  The rate of  principal  payments on the Assets in the  related  issuing
entity  (or,  in the case of  Mortgage  Securities  and Agency  Securities,  the
underlying assets related to the Mortgage  Securities and Agency  Securities) is
likely to be affected by the  existence of any Lock-out  Periods and  Prepayment
Premium  provisions of the mortgage loans underlying or comprising those Assets,
and by the extent to which the servicer of any of these  mortgage  loans is able
to  enforce  these  provisions.  Mortgage  loans  with a  Lock-out  Period  or a
Prepayment  Premium  provision,  to the extent  enforceable,  generally would be
expected to  experience a lower rate of  principal  prepayments  than  otherwise
identical mortgage loans without those provisions, with shorter Lock-out Periods
or with lower Prepayment Premiums.

        Because of the depreciating nature of manufactured housing, which limits
the possibilities  for refinancing,  and because the terms and principal amounts
of  manufactured  housing  contracts are generally  shorter and smaller than the
terms and  principal  amounts of mortgage  loans  secured by  site-built  homes,
changes in interest rates have a  correspondingly  small effect on the amount of
the  monthly   payments  on  mortgage   loans  secured  by   site-built   homes.
Consequently,  changes in interest  rates may play a smaller role in  prepayment
behavior  of  manufactured  housing  contracts  than  they do in the  prepayment
behavior of loans secured by mortgage on  site-built  homes.

                                       25



Conversely,  local economic  conditions and some of the other factors  mentioned
above may play a larger role in the prepayment behavior of manufactured  housing
contracts than they do in the prepayment  behavior of loans secured by mortgages
on site-built homes.

        If the  purchaser  of a Security  offered at a discount  calculates  its
anticipated  yield to  maturity  based on an assumed  rate of  distributions  of
principal  that is faster than that actually  experienced  on the Assets (or, in
the case of Mortgage  Securities and Agency  Securities,  the underlying  assets
related to the Mortgage Securities and Agency  Securities),  the actual yield to
maturity will be lower than that so calculated.  Conversely, if the purchaser of
a Security  offered at a premium  calculates its  anticipated  yield to maturity
based on an assumed rate of  distributions of principal that is slower than that
actually  experienced on the Assets (or, in the case of Mortgage  Securities and
Agency Securities,  the underlying assets related to the Mortgage Securities and
Agency  Securities),  the actual  yield to  maturity  will be lower than that so
calculated.  In either case, if so provided in the  prospectus  supplement for a
series of Notes or  Certificates,  as applicable,  the effect on yield on one or
more  classes of the Notes or  Certificates,  as  applicable,  of that series of
prepayments  of the Assets in the related  issuing  entity may be  mitigated  or
exacerbated  by any  provisions  for  sequential  or selective  distribution  of
principal to those classes.

        When a full  prepayment  is made on a mortgage  loan or a contract,  the
borrower is charged  interest on the principal  amount of the mortgage loan or a
contract so prepaid for the number of days in the month  actually  elapsed up to
the date of the  prepayment  or some other period  specified  in the  prospectus
supplement.  Generally,  the effect of prepayments in full will be to reduce the
amount  of  interest  paid  in the  following  month  to  holders  of  Notes  or
Certificates,  as applicable,  entitled to payments of interest because interest
on the  principal  amount of any mortgage  loan or a contract so prepaid will be
paid only to the date of  prepayment  rather  than for a full  month.  A partial
prepayment  of  principal is applied so as to reduce the  outstanding  principal
balance of the  related  mortgage  loan or a contract  as of its due date in the
month in which the  partial  prepayment  is  received  or some  other date as is
specified in the prospectus supplement.

        The timing of changes in the rate of  principal  payments  on the Assets
(or, in the case of Mortgage  Securities and Agency  Securities,  the underlying
assets  related  to  the  Mortgage   Securities  and  Agency   Securities)   may
significantly affect an investor's actual yield to maturity, even if the average
rate of distributions of principal is consistent with an investor's expectation.
In general,  the earlier a principal  payment is received on the mortgage  loans
and distributed on a Security,  the greater the effect on that investor's  yield
to maturity.  The effect on an investor's yield of principal  payments occurring
at a rate higher (or lower) than the rate  anticipated by the investor  during a
particular  period may not be offset by a similar  decrease (or increase) in the
rate of principal payments at a later time.

        The  securityholder  will  bear the risk of not being  able to  reinvest
principal  received  from a Security  at a yield at least  equal to the yield on
that Security.

PREPAYMENTS--MATURITY AND WEIGHTED AVERAGE LIFE

        The  rates  at which  principal  payments  are  received  on the  Assets
included in or comprising an issuing  entity and the rate at which  payments are
made from any credit  support or Cash Flow  Agreement for the related  series of
Notes or Certificates,  as applicable,  may affect the ultimate maturity and the
weighted average life of each class of that series.  Prepayments on the mortgage
loans or contracts  comprising or underlying the Assets in a particular  issuing
entity will generally  accelerate the rate at which principal is paid on some or
all of the classes of the Notes or Certificates,  as applicable,  of the related
series.

        If so provided  in the  prospectus  supplement  for a series of Notes or
Certificates,  as applicable,  one or more classes of Notes or Certificates,  as
applicable, may have a final scheduled

                                       26



Distribution  Date, which is the date on or before which the Security Balance of
the class of Notes or Certificates, as applicable, is scheduled to be reduced to
zero,  calculated  on the basis of the  assumptions  applicable  to that series.
Weighted average life refers to the average amount of time that will elapse from
the date of issue of a security  until each dollar of principal of that security
will be repaid to the investor. The weighted average life of a class of Notes or
Certificates, as applicable, of a series will be influenced by the rate at which
principal  on the  Assets  is paid to that  class,  which  may be in the form of
scheduled  amortization or prepayments (for this purpose,  the term "prepayment"
includes prepayments, in whole or in part, and liquidations due to default).

        In addition, the weighted average life of the Notes or Certificates,  as
applicable,  may be  affected  by the  varying  maturities  of the  Assets in an
issuing entity.  If any Assets in a particular  issuing entity have actual terms
to maturity less than those assumed in calculating final scheduled  Distribution
Dates for the classes of Notes or  Certificates,  as applicable,  of the related
series, one or more classes of these Notes or Certificates,  as applicable,  may
be fully paid before their respective final scheduled  Distribution  Dates, even
in the absence of  prepayments.  Accordingly,  the prepayment  experience of the
Assets  will,  to some  extent,  be a function of the mix of  mortgage  rates or
contract rates and  maturities of the mortgage loans or contracts  comprising or
underlying those Assets. See "Description of the Issuing Entities."

        Prepayments on loans are also commonly measured relative to a prepayment
standard or model, such as the Constant Prepayment Rate ("CPR") prepayment model
or the Standard Prepayment Assumption ("SPA") prepayment model. CPR represents a
constant  assumed rate of prepayment each month relative to the then outstanding
principal balance of a pool of loans for the life of those loans. SPA represents
an assumed  rate of  prepayment  each  month  relative  to the then  outstanding
principal  balance of a pool of loans.  A prepayment  assumption  of 100% of SPA
assumes  prepayment  rates of 0.2% per annum of the then  outstanding  principal
balance  of those  loans in the  first  month  of the life of the  loans  and an
additional 0.2% per annum in each month  thereafter  until the thirtieth  month.
Starting in the thirtieth month and in each month thereafter  during the life of
the loans,  100% of SPA assumes a constant  prepayment rate of 6% per annum each
month.

        Neither  CPR nor  SPA  nor any  other  prepayment  model  or  assumption
purports to be a historical description of prepayment experience or a prediction
of the  anticipated  rate of  prepayment  of any pool of  loans,  including  the
mortgage loans or contracts underlying or comprising the Assets.

        The prospectus  supplement for each series of Notes or Certificates,  as
applicable,  may contain  tables,  if  applicable,  setting  forth the projected
weighted  average  life of each  class  of  Offered  Notes or  Certificates,  as
applicable, of that series and the percentage of the initial Security Balance of
each class that would be  outstanding on specified  Distribution  Dates based on
the assumptions stated in the prospectus supplement,  including assumptions that
prepayments  on the mortgage  loans  comprising or underlying the related Assets
are made at rates corresponding to various percentages of CPR, SPA or some other
standard  specified in the prospectus  supplement.  These tables and assumptions
are intended to illustrate the  sensitivity of the weighted  average life of the
Notes or Certificates,  as applicable,  to various prepayment rates and will not
be intended to predict or to provide  information  that will enable investors to
predict  the  actual  weighted  average  life of the Notes or  Certificates,  as
applicable.  It is unlikely that  prepayment of any mortgage  loans or contracts
comprising  or  underlying  the  Assets  for  any  series  will  conform  to any
particular  level of CPR,  SPA or any other  rate  specified  in the  prospectus
supplement.

                                       27



OTHER FACTORS AFFECTING WEIGHTED AVERAGE LIFE

        TYPE OF LOAN

        Mortgage  Loans secured by Multifamily  Properties  may have  provisions
that  prevent  prepayment  for a number of years and may provide for payments of
interest only during a certain period  followed by  amortization of principal on
the basis of a schedule  extending  beyond the maturity of the related  mortgage
loan.  There can be no assurance as to the  respective  rates of  prepayment  of
these mortgage loans in either stable or changing interest rate environments.

        TYPE OF ASSET

        If specified in the  prospectus  supplement,  a number of mortgage loans
may have balloon  payments  due at maturity  (which,  based on the  amortization
schedule of those mortgage loans, may be a substantial  amount), and because the
ability of a borrower  to make a balloon  payment  typically  will depend on its
ability either to refinance the loan or to sell the related Mortgaged  Property,
there is a risk that a number of Balloon Payment Assets may default at maturity.
The ability to obtain  refinancing will depend on a number of factors prevailing
at the time refinancing or sale is required,  including real estate values,  the
borrower's  financial  situation,  prevailing  mortgage loan interest rates, the
borrower's  equity in the related  Mortgaged  Property,  tax laws and prevailing
general economic  conditions.  Neither the depositor,  the servicer,  the master
servicer,  nor  any of  their  affiliates  will be  obligated  to  refinance  or
repurchase  any mortgage  loan or to sell the Mortgaged  Property  except to the
extent provided in the prospectus supplement. In the case of defaults,  recovery
of proceeds may be delayed by, among other things, bankruptcy of the borrower or
adverse  conditions  in the market  where the  property is located.  To minimize
losses on defaulted  mortgage loans, the servicer may modify mortgage loans that
are in default or as to which a payment default is reasonably  foreseeable.  Any
defaulted  balloon  payment or  modification  that  extends  the  maturity  of a
mortgage  loan will tend to extend  the  weighted  average  life of the Notes or
Certificates,  as  applicable,  and may thus lengthen the period of time elapsed
from the date of issuance of a Security until it is retired.

        For some  mortgage  loans,  including  ARM Loans,  the mortgage  rate at
origination  may be below the rate  that  would  result if the index and  margin
relating to the mortgage loan were applied at  origination.  For some contracts,
the contract rate may be stepped up during its terms or may otherwise vary or be
adjusted.  Under the applicable underwriting standards,  the borrower under each
mortgage  loan or  contract  generally  will be  qualified  on the  basis of the
mortgage rate or contract rate in effect at origination. The repayment of any of
these  mortgage  loans or contracts may therefore be dependent on the ability of
the borrower to make larger level monthly  payments  following the adjustment of
the mortgage  rate or contract  rate. In addition,  some  mortgage  loans may be
subject to temporary buydown plans ("Buydown  Mortgage Loans") pursuant to which
the monthly payments made by the borrower during the early years of the mortgage
loan will be less than the scheduled  monthly payments on the mortgage loan (the
"Buydown Period"). The periodic increase in the amount paid by the borrower of a
Buydown Mortgage Loan during or at the end of the applicable  Buydown Period may
create a greater financial burden for the borrower, who might not have otherwise
qualified for a mortgage,  and may accordingly  increase the risk of default for
the related mortgage loan.

        The mortgage  rates on some ARM Loans  subject to negative  amortization
generally   adjust  monthly  and  their   amortization   schedules  adjust  less
frequently.  During a period of  rising  interest  rates as well as  immediately
after  origination  (initial  mortgage rates are generally lower than the sum of
the applicable  index at  origination  and the related margin over that index at
which  interest  accrues),  the amount of  interest  accruing  on the  principal
balance of those mortgage  loans may exceed the amount of the minimum  scheduled
monthly  payment on the mortgage  loans.  As a result,  a portion of the accrued
interest on negatively  amortizing  mortgage loans may be added to

                                       28



the  principal  balance of those  mortgage  loans and will bear  interest at the
applicable mortgage rate. The addition of any deferred interest to the principal
balance of any related class or classes of Notes or Certificates, as applicable,
will  lengthen the  weighted  average  life of those Notes or  Certificates,  as
applicable,  and may  adversely  affect  yield  to  holders  of  those  Notes or
Certificates,  as  applicable,  depending  on the price at which  those Notes or
Certificates,  as applicable,  were purchased.  In addition,  for some ARM Loans
subject to negative  amortization,  during a period of declining interest rates,
it might be expected that each minimum scheduled monthly payment on this type of
mortgage  loan would  exceed  the  amount of  scheduled  principal  and  accrued
interest on the principal  balance of that mortgage  loan, and since that excess
will be applied to reduce the principal  balance of the related class or classes
of Notes or  Certificates,  as  applicable,  the weighted  average life of those
Notes or Certificates,  as applicable,  will be reduced and may adversely affect
yield to holders of those Notes or Certificates, as applicable, depending on the
price at which those Notes or Certificates, as applicable, were purchased.

        As may be described in the prospectus supplement,  the related Agreement
may provide that all or a portion of the principal  collected on or with respect
to the  related  mortgage  loans may be  applied by the  related  trustee to the
acquisition of additional  HELOCs during a specified period (rather than used to
fund  payments of  principal  to  securityholders  during that  period) with the
result  that the  related  Notes or  Certificates,  as  applicable,  possess  an
interest-only  period,  also commonly referred to as a revolving  period,  which
will be  followed  by an  amortization  period.  Any of these  interest-only  or
revolving  periods may, upon the occurrence of particular events to be described
in the prospectus  supplement,  terminate before the end of the specified period
and result in the earlier than  expected  amortization  of the related  Notes or
Certificates, as applicable.

        In addition, and as may be described in the prospectus  supplement,  the
related  Agreement may provide that all or some of this collected  principal may
be  retained  by the  trustee  (and  held  in  specific  temporary  investments,
including  mortgage  loans) for a  specified  period  before  being used to fund
payments of principal to securityholders.

        The result of the retention  and temporary  investment by the trustee of
this principal  would be to slow the  amortization  rate of the related Notes or
Certificates,  as applicable,  relative to the amortization  rate of the related
mortgage  loans,  or to attempt to match the  amortization  rate of the  related
Notes or Certificates, as applicable, to an amortization schedule established at
the time the Notes or  Certificates,  as  applicable,  are  issued.  Any similar
feature applicable to any Notes or Certificates,  as applicable,  may end on the
occurrence of events to be described in the prospectus supplement,  resulting in
the current funding of principal payments to the related  securityholders and an
acceleration of the amortization of these Notes or Certificates, as applicable.

        TERMINATION

        If  specified  in the  prospectus  supplement,  a  series  of  Notes  or
Certificates,  as  applicable,  may be subject  to  optional  early  termination
through the repurchase of the Assets in the related  issuing entity by the party
specified in the prospectus supplement,  on any date on which the total Security
Balance of the Notes or Certificates,  as applicable, of that series declines to
a percentage  specified in the  prospectus  supplement  (generally not to exceed
10%) of the Initial Security Balance,  under the circumstances and in the manner
set forth therein.  In addition,  if so provided in the  prospectus  supplement,
some  classes of Notes or  Certificates,  as  applicable,  may be  purchased  or
redeemed   in  the  manner  set  forth   therein.   See   "Description   of  the
Securities--Termination."

        DEFAULTS

        The rate of defaults on the Assets will also affect the rate, timing and
amount of  principal  payments  on the Assets and thus the yield on the Notes or
Certificates, as applicable. In general,

                                       29



defaults on  mortgage  loans or  contracts  are  expected to occur with  greater
frequency in their early years.  The rate of default on mortgage  loans that are
refinance or limited  documentation  mortgage loans,  and on mortgage loans with
high Loan-to-Value Ratios, may be higher than for other types of mortgage loans.
Furthermore,  the rate and timing of prepayments,  defaults and  liquidations on
the  mortgage  loans or  contracts  will be  affected  by the  general  economic
condition of the region of the country in which the related Mortgaged Properties
or manufactured homes are located. The risk of delinquencies and loss is greater
and prepayments are less likely in regions where a weak or deteriorating economy
exists, as may be evidenced by, among other factors,  increasing unemployment or
falling property values.

        FORECLOSURES

        The number of foreclosures or repossessions  and the principal amount of
the mortgage  loans or contracts  comprising or  underlying  the Assets that are
foreclosed  or  repossessed  in relation to the number and  principal  amount of
mortgage loans or contracts that are repaid in accordance  with their terms will
affect the weighted  average life of the mortgage loans or contracts  comprising
or  underlying   the  Assets  and  that  of  the  related  series  of  Notes  or
Certificates, as applicable.

        REFINANCING

        At the request of a borrower,  the servicer may allow the refinancing of
a mortgage loan or contract in any issuing  entity by accepting  prepayments  on
the  mortgage  loan and  permitting a new loan secured by a mortgage on the same
property.  In the event of that refinancing,  the new loan would not be included
in the related issuing entity and,  therefore,  that refinancing  would have the
same effect as a prepayment in full of the related mortgage loan or contract.  A
servicer  may,  from time to time,  implement  programs  designed  to  encourage
refinancing. These programs may include modifications of existing loans, general
or targeted solicitations,  the offering of pre-approved  applications,  reduced
origination fees or closing costs, or other financial  incentives.  In addition,
servicers  may  encourage  the  refinancing  of  mortgage  loans  or  contracts,
including defaulted mortgage loans or contracts,  that would permit creditworthy
borrowers to assume the  outstanding  indebtedness  of those  mortgage  loans or
contracts.

        DUE-ON-SALE CLAUSES

        Acceleration of mortgage payments as a result of transfers of underlying
Mortgaged Property is another factor affecting  prepayment rates that may not be
reflected in the prepayment  standards or models used in the relevant prospectus
supplement.  A number of the mortgage loans comprising or underlying the Assets,
other than FHA loans and VA loans, may include "due-on-sale  clauses" that allow
the holder of the  mortgage  loans to demand  payment  in full of the  remaining
principal balance of the mortgage loans upon sale, transfer or conveyance of the
related Mortgaged Property.

        For  any  mortgage  loans,   except  as  set  forth  in  the  prospectus
supplement,  the servicer will generally  enforce any due-on-sale  clause to the
extent  it has  knowledge  of  the  conveyance  or  proposed  conveyance  of the
underlying  Mortgaged Property and it is entitled to do so under applicable law;
provided, however, that the servicer will not take any action in relation to the
enforcement  of  any  due-on-sale  provision  that  would  adversely  affect  or
jeopardize  coverage under any applicable  insurance policy.  See "Certain Legal
Aspects  of  Mortgage   Loans--Due-on-Sale  Clauses"  and  "Description  of  the
Agreements--Material   Terms  of  the  Pooling  and  Servicing   Agreements  and
Underlying Servicing Agreements--Due-on-Sale Provisions."

        The contracts, in general,  prohibit the sale or transfer of the related
manufactured   homes  without  the  consent  of  the  servicer  and  permit  the
acceleration of the maturity of the contracts by

                                       30



the servicer  upon any sale or transfer that is not consented to. It is expected
that the  servicer  will permit most  transfers  of  manufactured  homes and not
accelerate the maturity of the related  contracts.  In some cases,  the transfer
may be made by a delinquent borrower to avoid a repossession of the manufactured
home. In the case of a transfer of a manufactured  home after which the servicer
desires to accelerate the maturity of related contract,  the servicer's  ability
to do so will depend on the  enforceability  under state law of the  due-on-sale
clause.

                             STATIC POOL INFORMATION

        For each  mortgage  pool,  the issuing  entity will provide  static pool
information with respect to the experience of the sponsor,  or other appropriate
entity, in securitizing asset pools of the same type to the extent material.

        With respect to each series of securities,  the information  referred to
in this  section  will be provided  through an internet  web site at the address
disclosed in the related prospectus supplement.

                                   THE SPONSOR

        The  sponsor  will  be  DB   Structured   Products,   Inc.,  a  Delaware
corporation,  referred to herein as the Sponsor,  for each series of  securities
unless otherwise  indicated in the related  prospectus  supplement.  The Sponsor
maintains its principal office at 60 Wall Street,  New York, New York 10005. Its
telephone number is (212) 250-2500.

        During  fiscal year 2005,  the Sponsor  and its  affiliates  securitized
approximately $18.4 billion of residential mortgages.

        With respect to any series of securities, if so specified in the related
prospectus supplement,  the Sponsor will also act as servicer or master servicer
for the mortgage pool. If so, the Sponsor will service the  Designated  Mortgage
Assets in accordance with the description of the applicable servicing procedures
contained in this prospectus under "Description of the Securities."

                                  THE DEPOSITOR

        ACE Securities  Corp., the depositor,  is a special purpose  corporation
incorporated  in the State of Delaware on June 3, 1998. The principal  executive
offices of the  depositor  are located at 6525  Morrison  Boulevard,  Suite 318,
Charlotte,  North Carolina 28211.  Its telephone  number is (704) 365-0569.  The
depositor  does  not  have,  nor is it  expected  in the  future  to  have,  any
significant assets.

        The limited purposes of the depositor are, in general,  to acquire,  own
and sell mortgage loans and financial assets; to issue,  acquire,  own, hold and

GENERAL

        The Securities  issued in each series will include  either  asset-backed
certificates  (the  "Certificates")  or  asset-backed  notes (the  "Notes",  and
together with the  Certificates,  the  "Securities").  The  Certificates of each
series (including any class of Certificates not offered by this prospectus) will
represent the entire beneficial ownership interest in the issuing entity created
pursuant to the  related  Agreement.  The "Notes" of each series will  represent
indebtedness  of the  related  issuing  entity  and will be issued  and  secured
pursuant to an indenture.  Each series of Notes or Certificates,  as applicable,
will consist of one or more of the following classes of Notes or Certificates:

                                     principal   payments   primarily  from  the
                                     interest that accrues on specified  Accrual
                                     Classes.

                                     interest    otherwise   payable   to   such
                                     certificates   or  notes  is  allocated  to
                                     specified   classes  of   certificates   as
                                     principal  payments in  reduction  of their
                                     certificate   principal   balance  or  note
                                     principal    balance.    The    certificate
                                     principal balance or note principal balance
                                     of the Accrual  Class will be  increased to
                                     the  extent  such  accrued  interest  is so
                                     allocated.

        COMPANION                    A class that receives principal payments on
                                     any  distribution  date  only if  scheduled
                                     payments   have  been  made  on   specified
                                     planned   principal    classes,    targeted
                                     principal  classes or  scheduled  principal
                                     classes.

        COMPONENT                    A class  consisting  of  "components."  The
                                     components   of  a   class   of   component
                                     securities  may  have  different  principal
                                     and/or interest payment characteristics but
                                     together  constitute a single  class.  Each
                                     component   of   a   class   of   component
                                     securities  may be  identified  as  falling
                                     into one or more of the  categories in this
                                     list.

        FIXED RATE                   A class with an interest rate that is fixed

                                     based on an interest  rate that  fluctuates
                                     each  payment  period based on a designated
                                     index plus a specified margin.

        INTEREST ONLY OR IO          A class  of  securities  with no  principal
                                     balance  and  which  is  not   entitled  to
                                     principal   payments.    Interest   usually
                                     accrues  based  on  a  specified   notional
                                     amount.

        INVERSE FLOATING RATE        A   class   of    securities    where   the
                                     pass-through  rate  adjusts  based  on  the
                                     excess  between a specified  rate and LIBOR
                                     or another index.

                                       32



        LOCK OUT                     A class of securities which is "locked out"
                                     of certain payments, usually principal, for
                                     a specified period of time.

        PARTIAL ACCRUAL              A class  that  accretes  a  portion  of the
                                     amount of accrued interest  thereon,  which
                                     amount  will  be  added  to  the  principal
                                     balance  of such  class on each  applicable
                                     distribution  date,  with the  remainder of
                                     such  accrued  interest  to be  distributed
                                     currently  as interest on such class.  Such
                                     accretion  may  continue  until a specified
                                     event has  occurred  or until such  Partial
                                     Accrual class is retired.

        PRINCIPAL ONLY               A class of securities which is not entitled
                                     to interest payments.

        PLANNED AMORTIZATION CLASS   A  class  of  securities  with a  principal
                                     balance that is reduced based on a schedule
                                     of principal  balances,  assuming a certain
                                     range of prepayment rates on the underlying
                                     assets.

        SCHEDULED PRINCIPAL          A  class  that  is   designed   to  receive
                                     principal  payments  using a  predetermined
                                     principal   balance  schedule  but  is  not
                                     designated as a Planned  Principal Class or
                                     Targeted  Principal  Class.  In many cases,
                                     the  schedule  is derived by  assuming  two
                                     constant    prepayment    rates   for   the
                                     underlying assets.  These two rates are the
                                     endpoints for the  "structuring  range" for
                                     the scheduled principal class.

        SENIOR SUPPORT               A class that  absorbs the  realized  losses
                                     other  than   excess   losses   that  would
                                     otherwise  be  allocated  to a Super Senior
                                     Class   after  the   related   classes   of
                                     subordinated   securities   are  no  longer
                                     outstanding.

        SEQUENTIAL PAY               Classes that receive principal  payments in
                                     a  prescribed  sequence,  that do not  have
                                     predetermined  principal  balance schedules
                                     and that  under all  circumstances  receive
                                     payments of principal continuously from the
                                     first   distribution  date  on  which  they
                                     receive principal until they are retired. A
                                     single   class  that   receives   principal
                                     payments  before or after all other classes
                                     in the same  series  of  securities  may be
                                     identified as a sequential pay class.

        SUPER SENIOR                 A   class    that   will   not   bear   its
                                     proportionate   share  of  realized  losses
                                     (other than excess  losses) as its share is
                                     directed to another  class,  referred to as
                                     the   "support   class"   until  the  class
                                     principal  balance of the support  class is
                                     reduced to zero.

                                       33



        TARGET AMORTIZATION          A  class  of  securities  with a  principal
                                     balance   that  is   reduced   based  on  a
                                     scheduled of principal balances, assuming a
                                     certain targeted rate of prepayments on the
                                     related collateral.

        VARIABLE RATE                A class with an  interest  rate that resets
                                     periodically and is calculated by reference
                                     to the rate or rates of interest applicable
                                     to specified  assets or instruments  (e.g.,
                                     the  Loan  Rates  borne  by the  underlying
                                     loans).

        If specified in the prospectus supplement,  distributions on one or more
classes of a series of Notes or Certificates,  as applicable,  may be limited to
collections  from a  designated  portion  of the Assets in the  related  issuing
entity (each portion of the Assets, an "Asset Group").  Any of these classes may
include classes of Offered Notes or Offered Certificates, as applicable.

        Each  class of Notes or  Certificates,  as  applicable,  offered by this
prospectus and the related  prospectus  supplement  (the "Offered Notes" and the
"Offered  Certificates,"  respectively,  and together, the "Offered Securities")
will be issued in minimum  denominations  corresponding to the Security Balances
or,  in the  case of some  classes  of Strip  Securities,  notional  amounts  or
percentage interests specified in the prospectus supplement. The transfer of any
Offered Notes or Offered  Certificates,  as  applicable,  may be registered  and
those Notes or Certificates, as applicable, may be exchanged without the payment
of any service charge payable in connection  with that  registration of transfer
or exchange,  but the  depositor or the trustee or any agent of the depositor or
the trustee may require  payment of a sum  sufficient  to cover any tax or other
governmental  charge.  One  or  more  classes  of  Notes  or  Certificates,   as
applicable,  of a series may be issued in fully  registered,  certificated  form
("Definitive Notes" or "Definitive Certificates," and collectively,  "Definitive
Securities")   or  in  book-entry  form   ("Book-Entry   Notes"  or  "Book-Entry
Certificates," and collectively,  "Book-Entry  Securities"),  as provided in the
prospectus   supplement.   See   "Description   of  the   Securities--Book-Entry
Registration and Definitive Securities."
 Definitive   Notes  or  Definitive   Certificates,   as  applicable,   will  be
exchangeable for other Notes or Certificates,  as applicable,  of the same class
and series of a similar total Security  Balance,  notional  amount or percentage
interest but of different authorized denominations.

DISTRIBUTIONS

        Distributions  on the  Notes or  Certificates,  as  applicable,  of each
series will be made by or on behalf of the trustee on each  Distribution Date as
specified in the prospectus  supplement from the Available  Distribution  Amount
for that series and that Distribution Date.  Distributions (other than the final
distribution)  will  be  made  to the  persons  in  whose  names  the  Notes  or
Certificates,  as applicable, are registered at the close of business on, unless
a different  date is specified in the prospectus  supplement,  the last business
day of the month preceding the month in which the Distribution  Date occurs (the
"Record Date"), and the amount of each distribution will be determined as of the
close of  business  on the date  specified  in the  prospectus  supplement  (the
"Determination   Date").   All   distributions   for  each  class  of  Notes  or
Certificates,  as applicable,  on each  Distribution  Date will be allocated pro
rata among the outstanding  securityholders in that class or by random selection
or as described in the  prospectus  supplement.  Payments will be made either by
wire transfer in immediately  available funds to the account of a securityholder
at a bank or other entity having appropriate  facilities for these payments,  if
that securityholder has so notified the trustee or other person required to make
those  payments no later than the date  specified in the  prospectus  supplement
(and, if so provided in the prospectus supplement,  holds Notes or Certificates,
as applicable,  in the requisite amount specified in the prospectus supplement),
or by check  mailed to the  address of the person  entitled to the payment as it
appears on the Security Register; provided, however, that the final distribution
in retirement of the Notes or  Certificates,  as  applicable,  will be made only
upon presentation and surrender of the Notes or Certificates,  as applicable, at
the  location   specified  in  the  notice  to  securityholders  of  that  final
distribution.

supplement,  the entire Available  Distribution Amount will be distributed among
the  related  Notes or  Certificates,  as  applicable  (including  any  Notes or
Certificates,   as  applicable,   not  offered  by  this   prospectus)  on  each
Distribution  Date, and accordingly will be released from the issuing entity and
will not be available for any future distributions.

        The  prospectus  supplement  for a series of Notes or  Certificates,  as
applicable,  will describe any variation in the  calculation or  distribution of
the Available Distribution Amount for that series.

DISTRIBUTIONS OF INTEREST ON THE SECURITIES

        Each class of Notes or Certificates,  as applicable, (other than classes
of Strip Securities which have no Interest Rate), may have a different  Interest
Rate, which will be a fixed,  variable or adjustable rate at which interest will
accrue on that class or a component  of that class (the  "Interest  Rate" in the
case of  Certificates).  The indices  applicable to variable rate and adjustable
rate  classes will only be of a type that are  customarily  used in the debt and
fixed  income  markets to  measure  the cost of  borrowed  funds and will not be
indices linked to stocks or commodities.  The prospectus supplement will specify
the Interest  Rate for each class or component  or, in the case of a variable or
adjustable Interest Rate, the method for determining the Interest Rate. Interest
on the Notes or Certificates,  as applicable, will be calculated on the basis of
a 360-day  year  consisting  of  twelve  30-day  months  unless  the  prospectus
supplement specifies a different basis.

        Distributions of interest on the Notes or  Certificates,  as applicable,
of any class will be made on each  Distribution  Date  (other  than any class of
Accrual Securities,  which will be entitled to distributions of accrued interest
starting only on the Distribution Date, or under the circumstances, specified in
the  prospectus  supplement,  and any  class  of Strip  Securities  that are not
entitled  to any  distributions  of  interest)  based  on the  Accrued  Security
Interest for that class and that Distribution  Date,  subject to the sufficiency
of the portion of the Available  Distribution  Amount allocable to that class on
that  Distribution  Date.  Before any  interest is  distributed  on any class of
Accrual   Securities,   the  amount  of  Accrued  Security  Interest   otherwise
distributable  on that class will  instead be added to the  Security  Balance of
that class on each Distribution Date.

        For  each  class  of  Notes or  Certificates,  as  applicable,  and each
Distribution  Date  (other  than some  classes  of Strip  Securities),  "Accrued
Security  Interest" will be equal to interest accrued during the related Accrual
Period  on  the  outstanding   Security   Balance  of  the  class  of  Notes  or
Certificates,  as applicable,  immediately  before the Distribution Date, at the
applicable Interest Rate, reduced as described below.  Accrued Security Interest
on some classes of Strip Securities will be equal to interest accrued during the
related Accrual Period on the outstanding  notional amount of the Strip Security
immediately  before each  Distribution  Date, at the  applicable  Interest Rate,
reduced as described  below, or interest  accrual in the manner described in the
prospectus  supplement.  The method of  determining  the  notional  amount for a
particular  class  of  Strip  Securities  will be  described  in the  prospectus
supplement.  Reference to notional  amount is solely for  convenience in some of
the calculations  and does not represent the right to receive any  distributions
of  principal.  Unless  otherwise  provided in the  prospectus  supplement,  the
Accrued Security  Interest on a series of Notes or Certificates,  as applicable,
will be  reduced  in the  event of  prepayment  interest  shortfalls,  which are
shortfalls in collections  of interest for a full accrual period  resulting from
prepayments  before the due date in that accrual period on the mortgage loans or
contracts  comprising  or underlying  the Assets in the issuing  entity for that
series.  The  particular  manner in which these  shortfalls  are to be allocated
among some or all of the classes of Notes or  Certificates,  as  applicable,  of
that series will be  specified  in the  prospectus  supplement.  The  prospectus
supplement will also describe the extent to which the amount of Accrued Security
Interest  that is  otherwise  distributable  on  (or,  in the  case  of  Accrual
Securities,  that may otherwise be added to the Security  Balance of) a class of
Offered Notes or Offered Certificates, as applicable,

                                       36



may be reduced as a result of any other contingencies,  including delinquencies,
losses and deferred  interest on the mortgage  loans or contracts  comprising or
underlying the Assets in the related issuing entity.  Unless otherwise  provided
in the prospectus  supplement,  any reduction in the amount of Accrued  Security
Interest  otherwise  distributable  on a class  of  Notes  or  Certificates,  as
applicable,  by  reason of the  allocation  to that  class of a  portion  of any
deferred  interest on the mortgage  loans or contracts  comprising or underlying
the Assets in the related issuing entity will result in a corresponding increase
in the Security Balance of that class. See "Yield Considerations."

DISTRIBUTIONS OF PRINCIPAL OF THE SECURITIES

        The Notes or  Certificates,  as applicable,  of each series,  other than
some classes of Strip Securities,  will have a "Security  Balance" which, at any
time,  will equal the then  maximum  amount  that the holder will be entitled to
receive on principal  out of the future cash flow on the Assets and other assets
included in the related issuing entity.  The outstanding  Security  Balance of a
Security will be reduced:

        o   to the extent of  distributions  of principal on that  Security from
            time to time and

        o   if and to the extent provided in the prospectus  supplement,  by the
            amount of losses incurred on the related Assets.

        The outstanding Security Balance of a Security:

        o   may be  increased  in respect of  deferred  interest  on the related
            mortgage loans, to the extent provided in the prospectus  supplement
            and

        o   in the case of Accrual Securities,  will be increased by any related
            Accrued Security  Interest up until the  Distribution  Date on which
            distributions of interest are required to begin.

        If specified in the  prospectus  supplement,  the initial total Security
Balance of all classes of Notes or Certificates, as applicable, of a series will
be greater than the outstanding total principal balance of the related Assets as
of the applicable  Cut-off Date. The initial total Security  Balance of a series
and each class of the series will be  specified  in the  prospectus  supplement.
Distributions of principal will be made on each  Distribution  Date to the class
or  classes of Notes or  Certificates,  as  applicable,  in the  amounts  and in
accordance  with the  priorities  specified in the prospectus  supplement.  Some
classes of Strip  Securities  with no Security  Balance are not  entitled to any
distributions of principal.

        If specified in the related  prospectus  supplement,  the issuing entity
may issue notes or  certificates,  as applicable,  from time to time and use the
proceeds of this issuance to make principal payments with respect to a series.

REVOLVING PERIOD

        The applicable  prospectus  supplement may provide that all or a portion
of the principal collections may be applied by the trustee to the acquisition of
subsequent  HELOCs  or  asset-backed  or  mortgage  backed  securities  during a
specified  period  rather  than used to  distribute  payments  of  principal  to
noteholders  or  certificateholders,  as applicable,  during that period.  These
notes or  certificates,  as  applicable,  would then  possess an  interest  only
period,  also  commonly  referred  to as a  "Revolving  Period",  which  will be
followed by an "Amortization  Period",  during which principal will be paid. Any
interest  only  or  revolving  period  may  terminate  prior  to the  end of the

                                       37



specified period and result in the earlier than expected principal  repayment of
the notes or certificates, as applicable.

COMPONENTS

        To the extent specified in the prospectus supplement,  distribution on a
class of Notes or Certificates,  as applicable, may be based on a combination of
two or more different  components as described under "--General"  above. To that
extent,  the  descriptions set forth under  "--Distributions  of Interest on the
Securities"  and  "--Distributions  of Principal of the  Securities"  above also
relate  to  components  of the  component  class of Notes  or  Certificates,  as
applicable.  References in those  sections to Security  Balance may refer to the
principal  balance,  if any, of these  components  and reference to the Interest
Rate may refer to the Interest Rate, if any, on these components.

DISTRIBUTIONS ON THE SECURITIES OF PREPAYMENT PREMIUMS

        If so provided in the prospectus  supplement,  Prepayment  Premiums that
are  collected  on the  mortgage  loans in the  related  issuing  entity will be
distributed  on each  Distribution  Date to the  class  or  classes  of Notes or
Certificates,  as applicable,  entitled to the  distribution as described in the
prospectus supplement.

ALLOCATION OF LOSSES AND SHORTFALLS

        If so provided  in the  prospectus  supplement  for a series of Notes or
Certificates,  as  applicable,  consisting of one or more classes of Subordinate
Notes or Subordinate  Certificates,  as applicable,  on any Distribution Date in
respect of which losses or  shortfalls  in  collections  on the Assets have been
incurred,  the amount of those  losses or  shortfalls  will be borne  first by a
class of Subordinate Notes or Subordinate  Certificates,  as applicable,  in the
priority and manner and subject to the  limitations  specified in the prospectus
supplement.  See  "Description of Credit Support" for a description of the types
of  protection  that may be included  in an issuing  entity  against  losses and
shortfalls on Assets comprising that issuing entity.  The prospectus  supplement
for a  series  of  Notes or  Certificates,  as  applicable,  will  describe  the
entitlement, if any, of a class of Notes or Certificates,  as applicable,  whose
Security  Balance has been reduced to zero as a result of  distributions  or the
allocation  of losses on the  related  Assets to recover  any losses  previously
allocated to that class from  amounts  received on the Assets.  However,  if the
Security  Balance of a class of Notes or Certificates,  as applicable,  has been
reduced to zero as the result of  principal  distributions,  the  allocation  of
losses on the  Assets,  an  optional  termination  or an  optional  purchase  or
redemption,  that  class  will  no  longer  be  entitled  to  receive  principal
distributions from amounts received on the assets of the related issuing entity,
including  distributions in respect of principal losses previously  allocated to
that class.

ADVANCES IN RESPECT OF DELINQUENCIES

        If so provided in the  prospectus  supplement,  the  servicer or another
entity  described in the prospectus  supplement  will be required as part of its
servicing  responsibilities  to advance on or before each  Distribution Date its
own funds or funds held in the related  Collection Account that are not included
in the Available  Distribution  Amount for that Distribution  Date, in an amount
equal  to the  total of  payments  of (1)  principal  (other  than  any  balloon
payments) and (2) interest (net of related servicing fees and Retained Interest)
that were due on the Assets in that issuing entity during the related Due Period
and were delinquent on the related  Determination  Date, subject to a good faith
determination  that the advances will be reimbursable  from Related Proceeds (as
defined below). In the case of a series of Notes or Certificates, as applicable,
that  includes  one  or  more  classes  of  Subordinate   Notes  or  Subordinate
Certificates,  as applicable,  and if so provided in

                                       38



the  prospectus  supplement,   the  servicer's  (or  another  entity's)  advance
obligation may be limited only to the portion of those  delinquencies  necessary
to make the  required  distributions  on one or more  classes of Senior Notes or
Senior  Certificates,  as  applicable,  and/or  may be  subject  to a good faith
determination  that advances will be reimbursable not only from Related Proceeds
but also from collections on other Assets otherwise distributable on one or more
classes of those Subordinate Notes or Subordinate  Certificates,  as applicable.
See "Description of Credit Support."

        Advances are  intended to maintain a regular flow of scheduled  interest
and  principal  payments  to  holders  of the  class  or  classes  of  Notes  or
Certificates, as applicable,  entitled to the payments, rather than to guarantee
or insure against losses. Advances of the servicer's (or another entity's) funds
will be  reimbursable  only out of related  recoveries on the Assets  (including
amounts  received  under  any form of credit  support)  respecting  which  those
advances  were made (as to any Assets,  "Related  Proceeds")  and from any other
amounts  specified in the  prospectus  supplement,  including out of any amounts
otherwise  distributable  on  one  or  more  classes  of  Subordinate  Notes  or
Subordinate Certificates, as applicable, of that series; provided, however, that
any advance  will be  reimbursable  from any  amounts in the related  Collection
Account before any  distributions  being made on the Notes or  Certificates,  as
applicable, to the extent that the servicer (or some other entity) determines in
good faith that that  advance (a  "Nonrecoverable  Advance")  is not  ultimately
recoverable from Related  Proceeds or, if applicable,  from collections on other
Assets  otherwise   distributable  on  the  Subordinate   Notes  or  Subordinate
Certificates,  as  applicable.  If advances  have been made by the servicer from
excess  funds in the related  Collection  Account,  the  servicer is required to
replace these funds in that Collection  Account on any future  Distribution Date
to the extent that funds in that Collection  Account on that  Distribution  Date
are less than payments required to be made to  securityholders  on that date. If
specified in the  prospectus  supplement,  the  obligations  of the servicer (or
another  entity) to make advances may be secured by a cash advance reserve fund,
a surety  bond,  a letter of credit or  another  form of  limited  guaranty.  If
applicable, information regarding the characteristics of and the identity of any
borrower on any surety bond will be set forth in the prospectus supplement.

        If and to the  extent so  provided  in the  prospectus  supplement,  the
servicer (or another  entity)  will be entitled to receive  interest at the rate
specified in the prospectus  supplement on its outstanding  advances and will be
entitled to pay itself this interest  periodically  from general  collections on
the Assets before any payment to securityholders or as otherwise provided in the
related Agreement and described in the prospectus supplement.

        If specified in the prospectus  supplement,  the master  servicer or the
trustee  will be  required  to make  advances,  subject to  specific  conditions
described in the prospectus supplement, in the event of a servicer default.

REPORTS TO SECURITYHOLDERS

        With each distribution to holders of any class of Notes or Certificates,
as applicable, of a series, the servicer, the master servicer or the trustee, as
provided in the prospectus supplement,  will forward or cause to be forwarded to
each holder,  to the  depositor  and to any other parties as may be specified in
the related Agreement,  a statement containing the information  specified in the
prospectus  supplement,  or if no  information  is specified  in the  prospectus
supplement,  generally  setting forth, in each case to the extent applicable and

                (2)     the amount of that  distribution  to holders of Notes or
        Certificates, as applicable, of that class allocable to Accrued Security

        related Due Period, (a) the portion of the related liquidation  proceeds

        entity through  foreclosure or otherwise (an "REO Property") relating to
        a mortgage loan or contract and included in the issuing entity as of the
        end of the related Due Period, the date of acquisition;

                (10)    for each REO  Property  relating  to a mortgage  loan or
        contract and included in the issuing entity as of the end of the related
        Due Period,

                                Distribution   Date   (calculated   as  if  that
                                mortgage loan or contract were still outstanding
                                taking into account limited modifications to the
                                terms  of the  mortgage  loan  specified  in the
                                Agreement),

        offered  by  this   prospectus)   at  the  close  of  business  on  that
        Distribution Date, separately identifying any reduction in that Security
        Balance due to the  allocation  of any loss and increase in the Security
        Balance  of a  class  of  Accrual  Securities  if any  Accrued  Security

                                during the related Due Period.

        Reports,  whether monthly or annual, will be transmitted in paper format
to the holder of record of the class of  securities  contemporaneously  with the
distribution on that particular class. In addition,  the monthly reports will be
posted on a website as described below under "Available Information."

        Within a reasonable  period of time after the end of each calendar year,
the servicer,  the master servicer or the trustee, as provided in the prospectus
supplement, will furnish to each securityholder of record at any time during the
calendar year the information  required by the Internal Revenue Code of 1986, as
amended  (the  "Code")  and  applicable  regulations  under  the Code to  enable
securityholders   to  prepare  their  tax  returns.   See  "Description  of  the
Securities--Book-Entry Registration and Definitive Securities."

TERMINATION

        The  obligations  created by the  related  Agreement  for each series of
Notes or  Certificates,  as  applicable,  will  terminate  upon the  payment  to
securityholders of that series of all amounts held in the Collection Accounts or
by a servicer,  the master  servicer,  if any, or the trustee and required to be
paid to them pursuant to that  Agreement  following the earlier of (1) the final
payment or other  liquidation of the last Asset subject to the related Agreement
or the  disposition  of all property  acquired upon  foreclosure of any mortgage
loan or contract  subject to the  Agreement  and (2) the  purchase of all of the
assets of the issuing entity by the party  entitled to effect that  termination,
under  the  circumstances  and  in  the  manner  set  forth  in  the  prospectus
supplement.  In no event,  however,  will the issuing entity continue beyond the
date  specified in the prospectus  supplement.  Written notice of termination of
the Agreement will be given to each  securityholder,  and the final distribution
will be made only upon  presentation and surrender of the Notes or Certificates,
as applicable, at the location to be specified in the notice of termination.

        If  specified  in the  prospectus  supplement,  a  series  of  Notes  or
Certificates,  as  applicable,  may be subject  to  optional  early  termination
through the  purchase of the Assets in the related  issuing  entity by the party
specified  in the  prospectus  supplement,  under the  circumstances  and in the
manner set forth in the prospectus supplement.  If so provided in the prospectus
supplement,  upon the reduction of the Security  Balance of a specified class or
classes of Notes or Certificates,  as applicable, by a specified percentage, the
party specified in the prospectus  supplement will solicit bids for the purchase
of all assets of the issuing entity, or of a sufficient  portion of those assets
to retire that class or classes or purchase that class or classes at a price set
forth in the prospectus supplement, in each case, under the circumstances and in
the  manner  set forth in the  prospectus  supplement.  That price will at least
equal the outstanding  Security  Balances and any accrued and unpaid interest on
the  Security  Balances  (including  any unpaid  interest  shortfalls  for prior
Distribution  Dates).  Any sale of the  Assets  of the  issuing  entity  will be
without recourse to the issuing entity or the  securityholders.  Any purchase or
solicitation  of bids may be made only when the total  Security  Balance of that
class or classes  declines to a percentage  of the Initial  Security  Balance of
those Notes or Certificates,  as applicable (not to exceed 10%) specified in the
prospectus supplement. In addition, if so provided in the prospectus supplement,
some  classes of Notes or  Certificates,  as  applicable,  may be  purchased  or
redeemed  in the manner  set forth in the  prospectus  supplement  at a price at
least equal to the  outstanding  Security  Balance of each class so purchased or
redeemed and any accrued and unpaid interest on the Security Balance  (including
any unpaid interest shortfalls for prior Distribution  Dates). In the event that
any series of  certificates  or notes which  provides  for such a purchase,  the
certificates or notes will use the word "Callable" in their title.

OPTIONAL PURCHASES

        Subject to the  provisions of the applicable  Agreement,  the depositor,
the servicer or any other party  specified in the prospectus  supplement may, at
that party's  option,  repurchase  any mortgage loan that is in default or as to
which default is reasonably  foreseeable if, in the depositor's,  the servicer's
or any other party's judgment,  the related default is not likely to be cured by
the  borrower  or default is not likely to be  averted,  at a price equal to the
unpaid  principal  balance of the  mortgage  loan plus  accrued  interest on the
mortgage loan and under the conditions set forth in the prospectus supplement.

BOOK-ENTRY REGISTRATION AND DEFINITIVE SECURITIES

        GENERAL

        If provided for in the prospectus supplement, one or more classes of the
Offered  Notes or Offered  Certificates,  as  applicable,  of any series will be
issued as Book-Entry Notes or Book-Entry Certificates,  as applicable,  and each
of  these  classes  will  be   represented  by  one  or  more  single  Notes  or
Certificates,  as  applicable,  registered  in the  name  of a  nominee  for the
depository,  The  Depository  Trust  Company  ("DTC")  and,  if  provided in the
prospectus  supplement,  additionally  through Clearstream  Luxembourg,  societe
anonyme ("Clearstream  Luxembourg") or the Euroclear System ("Euroclear").  Each
class of Book-Entry  Notes or Book-Entry  Certificates,  as applicable,  will be
issued in one or more  certificates or notes, as the case may be, that equal the
initial  principal  amount of the  related  class of  Offered  Notes or  Offered
Certificates,  as  applicable,  and will  initially be registered in the name of
Cede & Co.

        No person  acquiring  an  interest in a  Book-Entry  Security  (each,  a
"Beneficial Owner") will be entitled to receive a Definitive Security, except as
set forth below under "--Definitive Securities."
 Unless and until  Definitive Notes or Definitive  Certificates,  as applicable,
are issued for the Book-Entry Notes or Book-Entry  Certificates,  as applicable,
under  the  limited   circumstances   described  in  the  applicable  prospectus
supplement or this prospectus, all references to actions by securityholders with
respect to the Book-Entry Notes or Book-Entry Certificates,  as applicable, will
refer  to  actions  taken  by DTC,  Clearstream  Luxembourg  or  Euroclear  upon
instructions from their  Participants (as defined below),  and all references in
this   prospectus  to   distributions,   notices,   reports  and  statements  to
securityholders with respect to the Book-Entry Notes or Book-Entry Certificates,
as applicable,  will refer to distributions,  notices, reports and statements to
DTC,  Clearstream  Luxembourg or Euroclear,  as applicable,  for distribution to
Beneficial  Owners  by DTC in  accordance  with  the  procedures  of DTC  and if
applicable, Clearstream Luxembourg and Euroclear.

        Beneficial  Owners  will  hold  their  Book-Entry  Notes  or  Book-Entry
Certificates,  as  applicable,  through  DTC in the  United  States,  or, if the
Offered  Notes or Offered  Certificates,  as  applicable,  are  offered for sale
globally,  through  Clearstream  Luxembourg  or  Euroclear in Europe if they are
participating  organizations  ("Participants")  of those  systems.  Participants
include  securities  brokers and dealers,  banks,  trust  companies and clearing
corporations  and may include some other  organizations.  Indirect access to the
DTC,  Clearstream  Luxembourg and Euroclear systems also is available to others,
such as banks,  brokers,  dealers  and trust  companies  that  clear  through or
maintain  a  custodial  relationship  with a  Participant,  either  directly  or
indirectly ("Indirect Participants").

        DTC

        DTC is a  limited-purpose  trust company organized under the laws of the
State  of New  York,  a  member  of the  Federal  Reserve  System,  a  "clearing
corporation"  within the meaning of the Uniform  Commercial  Code  ("UCC") and a
"clearing  agency"  registered  pursuant to the provisions

                                       43



of Section 17A of the Securities Exchange Act of 1934, as amended (the "Exchange
Act").  DTC was created to hold securities for its  Participants,  some of which
(and/or  their  representatives)  own DTC,  and  facilitate  the  clearance  and
settlement  of  securities   transactions   between  its  Participants   through
electronic  book-entry changes in their accounts,  thus eliminating the need for
physical movement of securities.  In accordance with its normal procedures,  DTC
is  expected to record the  positions  held by each of its  Participants  in the
Book-Entry Notes or Book-Entry Certificates, as applicable, whether held for its
own account or as a nominee for another person. In general, beneficial ownership
of Book-Entry Notes or Book-Entry Certificates,  as applicable,  will be subject
to the rules,  regulations and procedures  governing DTC and its Participants as
in effect from time to time.

        CLEARSTREAM LUXEMBOURG

        Clearstream Banking,  societe anonyme, 67 Bd Grande-Duchesse  Charlotte,
L-2967  Luxembourg  ("Clearstream,  Luxembourg"),  was  incorporated  in 1970 as
"Cedel S.A.", a company with limited  liability under  Luxembourg law (a societe
anonyme).  Cedel S.A. subsequently changed its name to Cedelbank. On January 10,
2000,  Cedelbank's parent company,  Cedel International,  societe anonyme ("CI")
merged its clearing, settlement and custody business with that of Deutsche Borse
Clearing AG ("DBC"). The merger involved the transfer by CI of substantially all
of its assets and  liabilities  (including its shares in CB) to a new Luxembourg
company, New Cedel International, societe anonyme ("New CI"), which is 50% owned
by CI and 50% owned by DBC's parent company  Deutsche Borse AG. The shareholders
of these two entities are banks,  securities dealers and financial institutions.
Cedel  International  currently has 92  shareholders,  including U.S.  financial
institutions or their subsidiaries. No single entity may own more than 5 percent
of Cedel International's stock.

        Further to the merger, the Board of Directors of New Cedel International
decided  to rename the  companies  in the group in order to give them a cohesive
brand  name.  The new brand name that was chosen is  "Clearstream".  With effect
from  January  14,  2000 New CI has  been  renamed  "Clearstream  International,
societe  anonyme".  On January 18,  2000,  Cedelbank  was  renamed  "Clearstream
Banking,  societe anonyme",  and Cedel Global Services was renamed  "Clearstream
Services, societe anonyme".

        On January 17, 2000 DBC was renamed "Clearstream Banking AG". This means
that there are now two entities in the  corporate  group  headed by  Clearstream
International which share the name "Clearstream  Banking", the entity previously
named "Cedelbank" and the entity previously named "Deutsche Borse Clearing AG".

        Clearstream,    Luxembourg    holds   securities   for   its   customers
("Clearstream,  Luxembourg  Participants")  and  facilitates  the  clearance and
settlement of securities transactions between Clearstream,  Luxembourg customers
through  electronic  book-entry  changes in accounts of Clearstream,  Luxembourg
customers,  thereby  eliminating the need for physical movement of certificates.
Transactions may be settled by Clearstream,  Luxembourg in any of 36 currencies,
including  United  States  Dollars.  Clearstream,  Luxembourg  provides  to  its
customers,  among  other  things,  services  for  safekeeping,   administration,
clearance and  settlement of  internationally  traded  securities and securities
lending  and  borrowing.  Clearstream,   Luxembourg  also  deals  with  domestic
securities  markets in over 30  countries  through  established  depository  and
custodial  relationships.  Clearstream,  Luxembourg  is  registered as a bank in
Luxembourg,  and  as  such  is  subject  to  regulation  by  the  Commission  de
Surveillance du Secteur Financier,  "CSSF",  which supervises  Luxembourg banks.
Clearstream,   Luxembourg's  customers  are  world-wide  financial  institutions
including  underwriters,  securities brokers and dealers, banks, trust companies
and clearing corporations.  Clearstream, Luxembourg's U.S. customers are limited
to securities brokers and dealers, and banks. Currently, Clearstream, Luxembourg
has approximately  2,000 customers  located in over 80 countries,  including all
major European countries, Canada, and the United

                                       44



States.  Indirect  access  to  Clearstream,  Luxembourg  is  available  to other
institutions  that clear  through or maintain a custodial  relationship  with an
account  holder  of  Clearstream,   Luxembourg.   Clearstream,   Luxembourg  has
established an electronic  bridge with Morgan Guaranty Trust Company of New York
as the Operator of the  Euroclear  System  (MGT/EOC)  in Brussels to  facilitate
settlement of trades between Clearstream, Luxembourg and MGT/EOC.

        EUROCLEAR

        Euroclear was created in 1968 to hold  securities  for its  Participants
and  to  clear  and  settle  transactions   between  its  Participants   through
simultaneous  electronic  book-entry delivery against payment,  thus eliminating
the  need  for  physical  movement  of  securities  and any  risk  from  lack of
simultaneous  transfers of securities and cash.  Transactions  may be settled in
any of 32  currencies,  including  United  States  dollars.  Euroclear  includes
various  other  services,   including  securities  lending  and  borrowing,  and
interfaces with domestic markets in several  countries  generally similar to the
arrangements for cross-market  transfers with DTC described above.  Euroclear is
operated by the Brussels, Belgium office of Morgan Guaranty Trust Company of New
York (the "Euroclear Operator"), under contract with Euroclear Clearance Systems
S.C., a Belgian  cooperative  corporation (the "Cooperative  Corporation").  All
operations are conducted by the Euroclear Operator, and all Euroclear securities
clearance  accounts and Euroclear  cash accounts are accounts with the Euroclear
Operator,  not  the  Cooperative   Corporation.   The  Cooperative   Corporation
establishes  policy  for  Euroclear  on  behalf of its  Participants.  Euroclear
Participants  include banks (including  central banks),  securities  brokers and
dealers and other  professional  financial  intermediaries.  Indirect  access to
Euroclear  is also  available  to other  firms that clear  through or maintain a
custodial  relationship  with a  Participant  of Euroclear,  either  directly or
indirectly.

        The  Euroclear  Operator  is the  Belgian  branch of a New York  banking
corporation  that  is a  member  bank  of the  Federal  Reserve  System,  and is
regulated and examined by the Board of Governors of the Federal  Reserve  System
and the New  York  State  Banking  Department,  as well as the  Belgian  Banking
Commission.

        Securities  clearance  accounts  and cash  accounts  with the  Euroclear
Operator are governed by the Terms and Conditions Governing Use of Euroclear and
the related Operating  Procedures of the Euroclear System and applicable Belgian
law (collectively,  the "Terms and Conditions"). The Terms and Conditions govern
transfers of securities and cash within Euroclear, withdrawals of securities and
cash from  Euroclear,  and receipts of payments  with respect to  securities  in
Euroclear.  All  securities  in Euroclear  are held on a fungible  basis without
attribution of specific  securities to specific  securities  clearance accounts.
The Euroclear Operator acts under the Terms and Conditions only on behalf of its
Participants,  and has no record of or relationship with persons holding through
Participants of Euroclear.

        Clearstream  Luxembourg  and  Euroclear  will hold omnibus  positions on
behalf  of  their  Participants   through  customers'   securities  accounts  in
Clearstream  Luxembourg's and Euroclear's names on the books of their respective
depositaries which in turn will hold positions in customers' securities accounts
in the depositaries  names on the books of DTC.  Citibank will act as depositary
for  Clearstream  Luxembourg  and JPMorgan Chase Bank will act as depositary for
Euroclear   (individually  the  "Relevant  Depositary"  and  collectively,   the
"European Depositaries").

        BENEFICIAL OWNERSHIP OF BOOK-ENTRY SECURITIES

        Except as  described  below,  no  Beneficial  Owner will be  entitled to
receive a physical certificate representing a Certificate,  or note representing
a Note.  Unless  and  until  Definitive  Notes or  Definitive  Certificates,  as
applicable,  are issued, it is anticipated that the only "securityholder" of the
Offered Notes or Offered  Certificates,  as  applicable,  will be Cede & Co., as
nominee of DTC.

                                       45



Beneficial Owners will not be  "Certificateholders"  as that term is used in any
Agreement,  nor "Noteholders" as that term is used in any indenture.  Beneficial
Owners  are  only  permitted  to  exercise  their  rights   indirectly   through
Participants, DTC, Clearstream Luxembourg or Euroclear, as applicable.

        The  Beneficial  Owner's  ownership  of a  Book-Entry  Security  will be
recorded on the records of the brokerage firm, bank, thrift institution or other
financial  intermediary  (each, a "Financial  Intermediary")  that maintains the
Beneficial   Owner's   account  for  that  purpose.   In  turn,   the  Financial
Intermediary's  ownership  of a  Book-Entry  Security  will be  recorded  on the
records  of DTC (or of a  Participant  that  acts  as  agent  for the  Financial
Intermediary,  whose interest will in turn be recorded on the records of DTC, if
the Beneficial Owner's Financial Intermediary is not a Participant of DTC and on
the records of Clearstream Luxembourg or Euroclear, as appropriate).

        Beneficial  Owners will receive all  distributions  of principal of, and
interest on, the Offered Notes or Offered Certificates,  as applicable, from the
trustee  through DTC and its  Participants.  While the Offered  Notes or Offered
Certificates,  as applicable,  are outstanding  (except under the  circumstances
described  below),  under the rules,  regulations  and  procedures  creating and
affecting  DTC  and  its  operations  (the  "Rules"),  DTC is  required  to make
book-entry  transfers among Participants on whose behalf it acts with respect to
the Offered Notes or Offered  Certificates,  as  applicable,  and is required to
receive and transmit distributions of principal of, and interest on, the Offered
Notes  or  Offered  Certificates,  as  applicable.   Participants  and  Indirect
Participants  with whom Beneficial  Owners have accounts with respect to Offered
Notes or Offered  Certificates,  as applicable,  are similarly  required to make
book-entry  transfers and receive and transmit  distributions on behalf of their
respective Beneficial Owners.  Accordingly,  although Beneficial Owners will not
possess certificates or notes, the Rules provide a mechanism by which Beneficial
Owners will receive distributions and will be able to transfer their interest.

        Beneficial   Owners   will  not   receive  or  be  entitled  to  receive
certificates or notes  representing  their  respective  interests in the Offered
Notes  or  Offered  Certificates,   as  applicable,  except  under  the  limited
circumstances  described below.  Unless and until Definitive Notes or Definitive
Certificates,   as  applicable,  are  issued,  Beneficial  Owners  who  are  not
Participants may transfer ownership of Offered Notes or Offered Certificates, as
applicable,  only through Participants and Indirect  Participants by instructing
the Participants and Indirect  Participants to transfer Offered Notes or Offered
Certificates, as applicable, by book-entry transfer, through DTC for the account
of the purchasers of the Offered Notes or Offered  Certificates,  as applicable,
which account is maintained with their respective Participants.  Under the Rules
and in  accordance  with DTC's  normal  procedures,  transfer  of  ownership  of
Book-Entry  Notes or Book-Entry  Certificates,  as applicable,  will be executed
through  DTC and the  accounts  of the  respective  Participants  at DTC will be
debited and credited. Similarly, the Participants and Indirect Participants will
make  debits or credits,  as the case may be, on their  records on behalf of the
selling and purchasing Beneficial Owners.

        Because of time zone differences,  any credits of securities received in
Clearstream  Luxembourg  or  Euroclear  as a  result  of a  transaction  with  a
Participant will be made during subsequent  securities settlement processing and
dated the business day following the DTC settlement  date.  These credits or any
transactions  in securities  settled during this  processing will be reported to
the  relevant  Participants  of  Clearstream  Luxembourg  or  Euroclear  on that
business day. Cash received in  Clearstream  Luxembourg or Euroclear as a result
of sales of securities by or through a Participant of Clearstream  Luxembourg or
Euroclear  to a  Participant  of DTC  will be  received  with  value  on the DTC
settlement date but will be available in the relevant Clearstream  Luxembourg or
Euroclear cash account only as of the business day following  settlement in DTC.
For information  with respect to tax  documentation  procedures  relating to the
Notes  or  Certificates,   as  applicable,  see  "Material  Federal  Income  Tax
Considerations -- Tax Treatment of Foreign Investors" in this prospectus and, if
the Book-Entry Notes or Book-Entry Certificates, as applicable,

                                       46



are globally  offered and the  prospectus  supplement  so provides,  see "Global
Clearance,  Settlement and Tax Documentation  Procedures -- Certain U.S. Federal
Income Tax Documentation Requirements" in Annex I to the prospectus supplement.

        Transfers between  Participants of DTC will occur in accordance with DTC
Rules.  Transfers  between  Participants of Clearstream  Luxembourg or Euroclear
will occur in accordance with their respective rules and operating procedures.

        Cross-market  transfers  between persons holding  directly or indirectly
through DTC, on the one hand, and directly or indirectly through Participants of
Clearstream  Luxembourg or Euroclear,  on the other,  will be effected in DTC in
accordance with the DTC Rules on behalf of the relevant  European  international
clearing system by the Relevant Depositary;  however,  cross-market transactions
will require  delivery of  instructions to the relevant  European  international
clearing system by the  counterparty in that system in accordance with its rules
and  procedures  and within  its  established  deadlines  (European  time).  The
relevant European  international  clearing system will, if the transaction meets
its settlement requirements,  deliver instructions to the Relevant Depositary to
take action to effect final  settlement on its behalf by delivering or receiving
securities  in DTC, and making or receiving  payment in  accordance  with normal
procedures  for same day funds  settlement  applicable to DTC.  Participants  of
Clearstream Luxembourg or Euroclear may not deliver instructions directly to the
European Depositaries.

        Distributions  on the Book-Entry  Notes or Book-Entry  Certificates,  as
applicable,  will be made on each  Distribution  Date by the Trustee to DTC. DTC
will be  responsible  for  crediting  the  amount  of each  distribution  to the
accounts of the applicable  Participants  of DTC in accordance with DTC's normal
procedures.  Each  Participant  of DTC will be  responsible  for  disbursing the
distribution  to the  Beneficial  Owners of the  Book-Entry  Notes or Book-Entry
Certificates,   as  applicable,   that  it  represents  and  to  each  Financial
Intermediary  for which it acts as agent.  Each Financial  Intermediary  will be
responsible  for  disbursing  funds to the  Beneficial  Owners of the Book-Entry
Notes or Book-Entry Certificates, as applicable, that it represents.

        Under a book-entry format,  Beneficial Owners of the Book-Entry Notes or
Book-Entry  Certificates,  as  applicable,  may  experience  some delay in their
receipt of payments,  because the distributions will be forwarded by the Trustee
to Cede & Co. Any  distributions on Notes or Certificates,  as applicable,  held
through  Clearstream  Luxembourg  or  Euroclear  will be  credited  to the  cash
accounts of  Participants  of Clearstream  Luxembourg or Euroclear in accordance
with the relevant  system's rules and procedures,  to the extent received by the
Relevant  Depositary.  These  distributions  will be subject to tax reporting in
accordance with relevant United States tax laws and  regulations.  See "Material
Federal  Income Tax  Considerations  -- REMICs --  Taxation  of Certain  Foreign
Investors" in this  prospectus.  Because DTC can only act on behalf of Financial
Intermediaries,  the ability of a Beneficial Owner to pledge Book-Entry Notes or
Book-Entry  Certificates,  as  applicable,  to persons or  entities  that do not
participate  in the depository  system,  or otherwise take actions in respect of
Book-Entry Notes or Book-Entry Certificates,  as applicable,  may be limited due
to the lack of  physical  securities  for the  Book-Entry  Notes  or  Book-Entry
Certificates,  as applicable.  In addition,  issuance of the Book-Entry Notes or
Book-Entry  Certificates,  as  applicable,  in  book-entry  form may  reduce the
liquidity of the securities in the secondary  market since  potential  investors
may be unwilling to purchase Notes or  Certificates,  as  applicable,  for which
they cannot obtain physical securities.

        Monthly and annual reports will be provided to Cede & Co., as nominee of
DTC, and may be made available by Cede & Co. to Beneficial  Owners upon request,
in accordance with the rules,  regulations and procedures creating and affecting
the depository,  and to the Financial  Intermediaries  to whose DTC accounts the
Book-Entry Notes or Book-Entry Certificates, as applicable, of Beneficial Owners
are credited.

                                       47



        Generally,  DTC will advise the applicable trustee that unless and until
Definitive Notes or Definitive Certificates, as applicable, are issued, DTC will
take any action  permitted to be taken by the holders of the Book-Entry Notes or
Book-Entry  Certificates,  as applicable,  under the Agreement or indenture,  as
applicable,  only at the direction of one or more  Financial  Intermediaries  to
whose  DTC  accounts  the  Book-Entry  Notes  or  Book-Entry  Certificates,   as
applicable,  are  credited,  to the extent  that  actions are taken on behalf of
Financial   Intermediaries  whose  holdings  include  the  Book-Entry  Notes  or
Book-Entry  Certificates,  as applicable.  If the Book-Entry Notes or Book-Entry
Certificates, as applicable, are globally offered, Clearstream Luxembourg or the
Euroclear Operator,  as the case may be, will take any other action permitted to
be taken by a securityholder under the Agreement or indenture, as applicable, on
behalf  of  a  Participant  of  Clearstream  Luxembourg  or  Euroclear  only  in
accordance  with its relevant rules and procedures and subject to the ability of
the Relevant  Depositary to effect those actions on its behalf  through DTC. DTC
may take actions, at the direction of the related Participants,  with respect to
some Offered Notes or Offered  Certificates,  as applicable,  that conflict with
actions taken with respect to other Offered  Notes or Offered  Certificates,  as
applicable.

        Although DTC,  Clearstream  Luxembourg  and Euroclear have agreed to the
foregoing  procedures  in order to facilitate  transfers of Book-Entry  Notes or
Book-Entry Certificates,  as applicable,  among Participants of DTC, Clearstream
Luxembourg and Euroclear, they are under no obligation to perform or continue to
perform these procedures and the procedures may be discontinued at any time.

        None of the depositor,  any master servicer,  any servicer, the trustee,
any securities  registrar or paying agent or any of their  affiliates  will have
any responsibility for any aspect of the records relating to or payments made on
account of beneficial  ownership interests of the Book-Entry Notes or Book-Entry
Certificates,  as applicable,  or for maintaining,  supervising or reviewing any
records relating to those beneficial ownership interests.

        DEFINITIVE SECURITIES

        Notes or  Certificates,  as applicable,  initially  issued in book-entry
form  will  be  issued  as  Definitive  Notes  or  Definitive  Certificates,  as
applicable,  to Beneficial  Owners or their nominees,  rather than to DTC or its
nominee only

                (1)     if the depositor advises the trustee in writing that DTC
        is no longer willing or able to properly discharge its  responsibilities
        as depository  for the Notes or  Certificates,  as  applicable,  and the
        depositor is unable to locate a qualified successor,

                (2)     if the depositor,  at its option,  in writing,  with the
        consent of the  applicable  Participants,  elects to end the  book-entry
        system through DTC or

                (3)     in accordance with any other provisions described in the
        prospectus supplement.

        Upon the  occurrence of any of the events  described in the  immediately
preceding  paragraph,  DTC  is  required  to  notify  all  Participants  of  the
availability  through DTC of  Definitive  Notes or Definitive  Certificates,  as
applicable,  for the Beneficial Owners. Upon surrender by DTC of the security or
securities  representing  the Book-Entry  Notes or Book-Entry  Certificates,  as
applicable,  together with instructions for registration, the trustee will issue
(or  cause  to  be  issued)  to  the  Beneficial   Owners  identified  in  those
instructions the Definitive Notes or Definitive Certificates,  as applicable, to
which they are entitled,  and  thereafter the trustee will recognize the holders
of  those  Definitive  Notes  or  Definitive  Certificates,  as  applicable,  as
securityholders under the Agreement.

                                       48



                          DESCRIPTION OF THE AGREEMENTS

AGREEMENTS APPLICABLE TO A SERIES

        REMIC SECURITIES AND GRANTOR TRUST SECURITIES

        Notes or  Certificates,  as  applicable,  representing  interests  in an
issuing entity,  or a portion of an issuing entity,  that the trustee will elect
to have treated as a real estate  mortgage  investment  conduit  ("REMIC") under
Sections  860A through 860G of the Code ("REMIC  Securities"),  or Grantor Trust
Securities  (as  defined in this  prospectus),  will be issued,  and the related
issuing entity will be created, pursuant to a pooling and servicing agreement or
trust agreement (in either case, generally referred to in this prospectus as the
"pooling and servicing agreement") among the depositor, the trustee and the sole
servicer or master  servicer,  as applicable.  The Assets of that issuing entity
will be transferred to the issuing entity and thereafter  serviced in accordance
with the terms of the pooling and  servicing  agreement.  In the event there are
multiple  servicers  of the Assets of that issuing  entity,  or in the event the
Securities consist of Notes, each servicer will perform its servicing  functions
pursuant to a related underlying  servicing  agreement.  Forms of the agreements
have  been  filed as  exhibits  to the  registration  statement  of  which  this
prospectus  is a part.  However,  the  provisions  of each  agreement  will vary
depending  upon the  nature  of the  related  securities  and the  nature of the
related issuing entity. The summaries  included herein describe  provisions that
may appear in a pooling  and  servicing  agreement  with  respect to a series of
Certificates or in either the servicing agreement or indenture with respect to a
series of Notes.  The  prospectus  supplement  for a series of  securities  will
describe  material  provisions  of the related  agreements  that differ from and
supplement the description thereof set forth below. The depositor will provide a
copy  of each  agreement  (without  exhibits)  that  relates  to any  series  of
securities  without  charge  upon  written  request  of a holder  of an  offered
security  of the  series  addressed  to it at its  principal  executive  offices
specified  in this  prospectus  under  "The  Depositor".  As to each  series  of
securities,  the  related  agreements  will be filed  with the  Commission  in a
current  report on Form 8-K  following  the  issuance of the  securities  to the
extent required to comply with the Securities Act of 1933 and Regulation AB.

        SECURITIES THAT ARE PARTNERSHIP INTERESTS FOR TAX PURPOSES AND NOTES

        Certificates,  as  applicable,  that  are  intended  to  be  treated  as
partnership  interests for tax purposes will be issued,  and the related issuing
entity will be created, pursuant to the pooling and servicing agreement or trust
agreement.

        A series of Notes  issued by an issuing  entity  that is  intended to be
treated as a partnership or  disregarded  entity for tax purposes will be issued
pursuant to an  indenture  between the related  issuing  entity and an indenture
trustee  named  in  the  prospectus  supplement.  The  issuing  entity  will  be
established  either as a statutory  business trust under the law of the State of
Delaware  or as a  common  law  trust  under  the law of the  State  of New York
pursuant  to a trust  agreement  between  the  depositor  and an  owner  trustee
specified in the  prospectus  supplement  relating to that series of Notes.  The
Assets securing  payment on the Notes will be serviced in accordance with a sale
and servicing agreement or servicing agreement.

MATERIAL TERMS OF THE POOLING AND SERVICING  AGREEMENTS AND UNDERLYING SERVICING
AGREEMENTS

        GENERAL

        The following summaries describe the material provisions that may appear
in each  pooling  and  servicing  agreement,  sale and  servicing  agreement  or
servicing agreement (each an

                                       49



"Agreement").  The prospectus  supplement for a series of Notes or Certificates,
as  applicable,  will describe any  provision of the Agreement  relating to that
series  that  materially  differs  from  the  description  of  those  provisions
contained in this  prospectus.  The  summaries do not purport to be complete and
are subject to, and are qualified by reference to, all of the  provisions of the
Agreement for each issuing entity and the description of those provisions in the
prospectus  supplement.  The provisions of each Agreement will vary depending on
the nature of the Notes or Certificates,  as applicable,  to be issued under the
Agreement  and  the  nature  of the  related  issuing  entity.  As  used in this
prospectus  for any series,  the term  "Security"  refers to all of the Notes or
Certificates,  as  applicable,  of that  series,  whether or not offered by this
prospectus  and by the  prospectus  supplement,  unless  the  context  otherwise
requires.  A form of a pooling  and  servicing  agreement  has been  filed as an
exhibit to the  Registration  Statement of which this  prospectus is a part. The
depositor  will provide a copy of the pooling and servicing  agreement  (without
exhibits)  relating  to any  series  of Notes or  Certificates,  as  applicable,
without charge upon written request of a securityholder of that series addressed
to ACE Securities Corp., 6525 Morrison Boulevard,  Suite 318,  Charlotte,  North
Carolina 28211, Attention: Evelyn Echevarria.

        The servicer or master  servicer and the trustee for any series of Notes
or Certificates,  as applicable,  will be named in the prospectus supplement. In
the event there are multiple  servicers for the Assets in an issuing  entity,  a
master  servicer  will  perform  some  of the  administration,  calculation  and
reporting  functions  for that  issuing  entity and will  supervise  the related
servicers pursuant to a pooling and servicing agreement.  For a series involving
a master  servicer,  references in this prospectus to the servicer will apply to
the master servicer where non-servicing  obligations are described. If specified
in the  prospectus  supplement,  a manager  or  administrator  may be  appointed
pursuant to the  pooling  and  servicing  agreement  for any  issuing  entity to
administer that issuing entity.

        ASSIGNMENT OF ASSETS; REPURCHASES

        At the time of  issuance  of any  series  of Notes or  Certificates,  as
applicable,  the  depositor  will  assign  (or  cause  to be  assigned)  to  the
designated  trustee the Assets to be included  in the  related  issuing  entity,
together  with all  principal  and interest to be received on or with respect to
those Assets after the Cut-off Date, other than principal and interest due on or
before the Cut-off Date and other than any Retained Interest.  The trustee will,
concurrently  with  that  assignment,  deliver  the  Notes or  Certificates,  as
applicable,  to the  depositor  in exchange  for the Assets and the other assets
comprising the issuing entity for that series.  Each Asset will be identified in
a schedule appearing as an exhibit to the related Agreement.  That schedule will
include detailed information to the extent available and relevant

                (1)     in respect of each mortgage loan included in the related
        issuing  entity,  including the city and state of the related  Mortgaged
        Property  and  type  of  that  property,   the  mortgage  rate  and,  if
        applicable,  the applicable index, margin,  adjustment date and any rate
        cap  information,  the original  and  remaining  term to  maturity,  the
        original and outstanding  principal balance and balloon payment, if any,
        the  Loan-to-Value  Ratio  as of the  date  indicated  and  payment  and
        prepayment provisions, if applicable;

                (2)     in  respect of each  contract  included  in the  related
        issuing  entity,  including  the  outstanding  principal  amount and the
        contract rate; and

                (3)     in  respect  of  each   Mortgage   Security  and  Agency
        Security, the original and outstanding principal amount, if any, and the
        interest rate on the Mortgage Security or Agency Security.

        For each mortgage loan, except as otherwise  specified in the prospectus
supplement,  the depositor  will deliver or cause to be delivered to the trustee
(or to the custodian hereinafter

                                       50



referred  to)  particular  loan  documents,  which will  generally  include  the
original mortgage note endorsed,  without recourse,  in blank or to the order of
the  trustee,  the  original  Mortgage  (or a  certified  copy  of the  original
Mortgage) with evidence of recording  indicated on the original  Mortgage and an
assignment  of the  Mortgage  to the trustee in  recordable  form.  However,  an
issuing entity may include  mortgage  loans where the original  mortgage note is
not  delivered  to the trustee if the  depositor  delivers to the trustee or the
custodian a copy or a duplicate original of the mortgage note,  together with an
affidavit  certifying  that the original of the  mortgage  note has been lost or
destroyed.  For those  mortgage  loans,  the trustee (or its nominee) may not be
able to enforce the mortgage note against the related borrower. The Asset Seller
or other entity specified in the prospectus supplement will be required to agree
to  repurchase,  or  substitute  for,  each  of  these  mortgage  loans  that is
subsequently in default if the enforcement thereof or of the related Mortgage is
materially  adversely affected by the absence of the original mortgage note. The
related  Agreement  will  generally  require  the  depositor  or  another  party
specified  in  the  prospectus  supplement  to  promptly  cause  each  of  these
assignments of Mortgage to be recorded in the appropriate public office for real
property records, except in the State of California or in other states where, in
the opinion of counsel  acceptable to the trustee,  recording is not required to
protect the trustee's interest in the related mortgage loan against the claim of
any subsequent transferee or any successor to or creditor of the depositor,  the
servicer,  the  relevant  Asset Seller or any other prior holder of the mortgage
loan.

        The trustee (or a  custodian)  will review the mortgage  loan  documents
within a specified  period of days after receipt of the mortgage loan documents,
and the  trustee (or a  custodian)  will hold those  documents  in trust for the
benefit  of the  securityholders.  If any of  these  documents  are  found to be
missing or defective in any material  respect,  the trustee (or that  custodian)
will  immediately  notify the servicer and the depositor,  and the servicer will
immediately  notify the relevant  Asset Seller or other entity  specified in the
prospectus  supplement.  If the Asset Seller  cannot cure the omission or defect
within a specified  number of days after receipt of that notice,  then the Asset
Seller or other entity specified in the prospectus supplement will be obligated,
within a  specified  number of days of  receipt  of that  notice,  to either (1)
repurchase  the related  mortgage  loan from the trustee at a price equal to the
sum of the unpaid  principal  balance of the mortgage loan,  plus unpaid accrued
interest at the interest rate for that Asset from the date as to which  interest
was last paid to the due date in the Due Period in which the  relevant  purchase
is to occur,  plus  servicing  expenses  that are  payable to the  servicer,  or
another price as specified in the prospectus  supplement (the "Purchase  Price")
or (2) substitute a new mortgage  loan.  There can be no assurance that an Asset
Seller or other named  entity  will  fulfill  this  repurchase  or  substitution
obligation,  and neither the  servicer  nor the  depositor  will be obligated to
repurchase  or  substitute  for that  mortgage loan if the Asset Seller or other
named entity defaults on its obligation.

        This repurchase or substitution  obligation  constitutes the sole remedy
available to the  securityholders  or the trustee for omission of, or a material
defect in, a constituent  document.  To the extent  specified in the  prospectus
supplement,  in  lieu  of  curing  any  omission  or  defect  in  the  Asset  or
repurchasing  or  substituting  for that Asset,  the Asset Seller or other named
entity may agree to cover any losses  suffered by the issuing entity as a result
of that breach or defect.

        Notwithstanding  the preceding three paragraphs,  the documents for Home
Equity Loans, home improvement  contracts and unsecured home improvements  loans
will be delivered to the trustee (or a custodian)  only to the extent  specified
in the prospectus supplement.  Generally these documents will be retained by the
servicer,  which may also be the Asset Seller.  In addition,  assignments of the
related  Mortgages to the trustee will be recorded only to the extent  specified
in the prospectus supplement.

        For each  contract,  the  servicer,  which may also be the asset seller,
generally will maintain custody of the original contract and copies of documents
and instruments related to each contract

                                       51



and the security  interest in the manufactured  home securing each contract.  To
give notice of the right,  title and  interest of the trustee in the  contracts,
the  depositor  will cause  UCC-1  financing  statements  to be  executed by the
related  asset seller  identifying  the  depositor  as secured  party and by the
depositor  identifying  the  trustee as the  secured  party  and,  in each case,
identifying  all  contracts  as  collateral.  The  contracts  will be stamped or
otherwise  marked to reflect their  assignment from the depositor to the issuing
entity only to the extent specified in the prospectus supplement. Therefore, if,
through negligence, fraud or otherwise, a subsequent purchaser were able to take
physical  possession of the contracts  without  notice of that  assignment,  the
interest of the trustee in the contracts could be defeated.

        While the contract  documents will not be reviewed by the trustee or the
servicer, if the servicer finds that any document is missing or defective in any
material  respect,  the  servicer  will be  required to  immediately  notify the
depositor  and the  relevant  asset  seller  or other  entity  specified  in the
prospectus supplement.  If the asset seller or some other entity cannot cure the
omission  or defect  within a  specified  number of days  after  receipt of this
notice,  then the asset seller or that other entity will be obligated,  within a
specified  number of days of receipt of this notice,  to repurchase  the related
contract from the trustee at the purchase price or substitute for that contract.
There can be no assurance  that an asset seller or any other entity will fulfill
this  repurchase or  substitution  obligation,  and neither the servicer nor the
depositor will be obligated to repurchase or substitute for that contract if the
asset seller or any other entity defaults on its obligation.  This repurchase or
substitution   obligation   constitutes   the  sole  remedy   available  to  the
securityholders  or the  trustee  for  omission  of, or a material  defect in, a
constituent document. To the extent specified in the prospectus  supplement,  in
lieu  of  curing  any  omission  or  defect  in the  asset  or  repurchasing  or
substituting  for that  asset,  the asset  seller  may agree to cover any losses
suffered by the issuing entity as a result of that breach or defect.

        Mortgage Securities and Agency Securities will be registered in the name
of the  trustee or its  nominee on the books of the issuer or  guarantor  or its
agent or, in the case of Mortgage  Securities and Agency  Securities issued only
in  book-entry  form,  through  the  depository  with  respect  to the  Mortgage
Securities and Agency Securities,  in accordance with the procedures established
by  the  issuer  or  guarantor  for  registration  of  those  certificates,  and
distributions  on those  securities to which the issuing entity is entitled will
be made directly to the trustee.

        REPRESENTATIONS AND WARRANTIES; REPURCHASES

        To the extent provided in the prospectus  supplement the depositor will,
for each Asset, assign  representations  and warranties,  as of a specified date
(the person making those representations and warranties, the "Warranting Party")
covering, by way of example, the following types of matters:

        o   the  accuracy  of the  information  set forth for that  Asset on the
            schedule of Assets appearing as an exhibit to the related Agreement;

        o   in the case of a mortgage  loan,  the  existence of title  insurance
            insuring the lien  priority of the mortgage loan and, in the case of
            a  contract,  that  the  contract  creates  a valid  first  security
            interest in or lien on the related manufactured home;

        o   the authority of the Warranting Party to sell the Asset;

        o   the payment status of the Asset;

                                       52



        o   in  the  case  of  a  mortgage  loan,  the  existence  of  customary
            provisions  in the  related  mortgage  note and  Mortgage  to permit
            realization  against  the  Mortgaged  Property of the benefit of the
            security of the Mortgage; and

        o   the existence of hazard and extended  perils  insurance  coverage on
            the Mortgaged Property or manufactured home.

        Any  Warranting  Party shall be an Asset  Seller or an  affiliate of the
Asset  Seller  or any  other  person  acceptable  to the  depositor  and will be
identified in the prospectus supplement.

        Representations and warranties made in respect of an Asset may have been
made as of a date before the  applicable  Cut-off Date. A substantial  period of
time may have elapsed between that date and the date of initial  issuance of the
related series of Notes or Certificates,  as applicable,  evidencing an interest
in that  Asset.  In the  event of a breach  of any of these  representations  or
warranties,  the  Warranting  Party will be obligated  to reimburse  the issuing
entity for losses caused by that breach or either cure that breach or repurchase
or replace the affected Asset as described below. Since the  representations and
warranties may not address events that may occur  following the date as of which
they were made, the Warranting Party will have a reimbursement, cure, repurchase
or substitution  obligation in connection  with a breach of that  representation
and warranty  only if the relevant  event that causes that breach  occurs before
that date.  That party  would have no  obligations  if the  relevant  event that
causes that breach occurs after that date.

        Each Agreement will provide that the servicer  and/or trustee or another
entity  identified  in the  prospectus  supplement  will be  required  to notify
promptly the relevant  Warranting Party of any breach of any  representation  or
warranty made by it in respect of an Asset that materially and adversely affects
the value of that Asset or the  interests in the  prospectus  supplement  of the
securityholders.  If the  Warranting  Party  cannot  cure that  breach  within a
specified  period  following  the date on which that party was  notified of that
breach,  then the  Warranting  Party will be obligated to repurchase  that Asset
from the trustee within a specified period from the date on which the Warranting
Party was  notified  of that  breach,  at the  Purchase  Price  therefor.  If so
provided in the prospectus  supplement for a series, a Warranting Party,  rather
than  repurchase  an  Asset as to which a breach  has  occurred,  will  have the
option, within a specified period after initial issuance of that series of Notes
or  Certificates,  as  applicable,  to cause the  removal of that Asset from the
issuing  entity  and  substitute  in its  place  one or more  other  Assets,  as
applicable,  in  accordance  with  the  standards  described  in the  prospectus
supplement.  If so  provided  in  the  prospectus  supplement  for a  series,  a
Warranting  Party,  rather than  repurchase or substitute an Asset as to which a
breach has occurred, will have the option to reimburse the issuing entity or the
securityholders  for any  losses  caused  by that  breach.  This  reimbursement,
repurchase or substitution  obligation will constitute the sole remedy available
to securityholders or the trustee for a breach of representation by a Warranting
Party.

        Neither the  depositor  (except to the extent that it is the  Warranting
Party) nor the servicer will be obligated to purchase or substitute for an Asset
if a Warranting  Party defaults on its obligation to do so, and no assurance can
be given  that the  Warranting  Parties  will carry out those  obligations  with
respect to the Assets.

        A  servicer  will make  representations  and  warranties  regarding  its
authority to enter into, and its ability to perform its obligations  under,  the
related  Agreement.  A  breach  of  any  representation  of  the  servicer  that
materially and adversely affects the interests of the  securityholders and which
continues unremedied for the number of days specified in the Agreement after the
discovery of the breach by the servicer or the receipt of written notice of that
breach by the servicer  from the trustee,  the depositor or the holders of Notes
or  Certificates,  as  applicable,  evidencing  not less than 25% of the  voting
rights or other percentage specified in the

                                       53



related Agreement, will constitute an Event of Default under that Agreement. See
"Events of Default under the  Agreement" and "Rights Upon Event of Default under
the Agreements."

        COLLECTION ACCOUNT AND RELATED ACCOUNTS

        GENERAL.  The  servicer  and/or the  trustee  will,  as to each  issuing
entity,  establish and maintain or cause to be established and maintained one or
more  separate  accounts for the  collection  of payments on the related  Assets
(collectively,  the "Collection Account"),  which must be an account or accounts
that either:

        o   are insured by the Bank  Insurance  Fund or the Savings  Association
            Insurance Fund of the Federal Deposit Insurance Corporation ("FDIC")
            (to the limits  established by the FDIC) and the uninsured  deposits
            in which are otherwise  secured so that the  securityholders  have a
            claim  with  respect  to the funds in the  Collection  Account  or a
            perfected first priority  security  interest  against any collateral
            securing  those  funds that is  superior  to the claims of any other
            depositors or general  creditors of the  institution  with which the
            Collection Account is maintained, or

        o   are  maintained  with a  bank  or  trust  company,  and in a  manner
            satisfactory  to the rating  agency or agencies  rating any class of
            Notes or Certificates, as applicable, of that series.

        Investment  of  amounts in the  Collection  Account is limited to United
States government securities and other investment grade obligations specified in
the Agreement ("Permitted Investments").  A Collection Account may be maintained
as an interest  bearing or a non-interest  bearing account and the funds held in
the Collection Account may be invested pending each succeeding Distribution Date
in  short-term  Permitted  Investments.  The  master  servicer  will  have  sole
discretion to determine the particular  investments  made so long as it complies
with the investment terms of the related pooling and servicing  agreement or the
related servicing  agreement and indenture.  Any interest or other income earned
on funds in the  Collection  Account  will,  unless  otherwise  specified in the
prospectus  supplement,  be paid to the servicer or its  designee as  additional
servicing  compensation.  The  Collection  Account  may be  maintained  with  an
institution that is an affiliate of the servicer,  if applicable,  provided that
that institution  meets the standards  imposed by the rating agency or agencies.
If permitted by the rating agency or agencies,  a Collection Account may contain
funds relating to more than one series of mortgage pass-through certificates and
may contain other funds  respecting  payments on mortgage loans belonging to the
servicer or serviced or master serviced by it on behalf of others.

        DEPOSITS.  A  servicer  or the  trustee  will  deposit  or  cause  to be
deposited in the Collection  Account for one or more issuing entities on a daily
basis,  or any other period  provided in the related  Agreement,  the  following
payments and  collections  received,  or advances  made,  by the servicer or the
trustee or on its behalf after the Cut-off  Date (other than  payments due on or
before the Cut-off Date,  and exclusive of any amounts  representing  a Retained
Interest), except as otherwise provided in the Agreement:

                (1)     all   payments  on  account  of   principal,   including
        principal prepayments, on the Assets;

                (2)     all  payments  on account  of  interest  on the  Assets,
        including  any  default  interest  collected,  in each  case  net of any
        portion retained by a servicer as its servicing  compensation and net of
        any Retained Interest;

                                       54



                (3)     Liquidation  Proceeds and Insurance  Proceeds,  together
        with the net  proceeds  on a monthly  basis  with  respect to any Assets
        acquired for the benefit of securityholders;

                (4)     any amounts paid under any  instrument or drawn from any
        fund that constitutes  credit support for the related series of Notes or
        Certificates,  as applicable,  as described under "Description of Credit
        Support;"

                (5)     any advances made as described under "Description of the
        Securities--Advances in Respect of Delinquencies;"

                (6)     any  amounts  paid  under  any Cash Flow  Agreement,  as
        described  under  "Description  of  the  Issuing   Entities--Cash   Flow
        Agreements;"

                (7)     all proceeds of any Asset or, with respect to a mortgage
        loan, property acquired in respect of the mortgage loan purchased by the
        depositor,  any Asset Seller or any other specified  person as described
        above under "--Assignment of Assets; Repurchases" and "--Representations
        and  Warranties;  Repurchases,"  all proceeds of any defaulted  mortgage
        loan purchased as described  below under  "--Realization  Upon Defaulted
        Assets,"  and all proceeds of any Asset  purchased  as  described  under
        "Description of the Securities--Termination;"

                (8)     any  amounts  paid  by  a  servicer  to  cover  interest
        shortfalls arising out of the prepayment of Assets in the issuing entity
        as described below under "--Retained  Interest;  Servicing  Compensation
        and Payment of Expenses;"

                (9)     to the extent that any of these items do not  constitute
        additional servicing compensation to a servicer, any payments on account
        of modification  or assumption  fees, late payment charges or Prepayment
        Premiums on the Assets;

                (10)    all payments  required to be deposited in the Collection
        Account with respect to any deductible  clause in any blanket  insurance
        policy described below under "--Hazard Insurance Policies;"

                (11)    any amount required to be deposited by a servicer or the
        trustee in  connection  with  losses  realized  on  investments  for the
        benefit of the  servicer  or the  trustee,  as the case may be, of funds
        held in the Collection Account; and

                (12)    any  other  amounts  required  to be  deposited  in  the
        Collection Account as provided in the related Agreement and described in
        the prospectus supplement.

        WITHDRAWALS.  A  servicer  or the  trustee  may,  from  time  to time as
provided in the related Agreement,  make withdrawals from the Collection Account
for each issuing entity for any of the following  purposes,  except as otherwise
provided in the Agreement:

                (1)     to make  distributions  to the  securityholders  on each
        Distribution Date;

                (2)     to  reimburse  a  servicer  for   unreimbursed   amounts
        advanced as described under "Description of the  Securities--Advances in
        Respect  of  Delinquencies,"  which  reimbursement  is to be made out of
        amounts  received  that were  identified  and applied by the servicer as
        late collections of interest (net of related servicing fees and Retained
        Interest)  on and  principal  of the  particular  Assets  for  which the
        advances  were  made or out of  amounts  drawn  under any form of credit
        support with respect to those Assets;

                                       55



                (3)     to reimburse a servicer for unpaid servicing fees earned
        and unreimbursed  servicing expenses incurred with respect to Assets and
        properties acquired in respect of the Assets,  which reimbursement is to
        be made out of amounts that represent Liquidation Proceeds and Insurance
        Proceeds  collected on the  particular  Assets and  properties,  and net
        income collected on the particular properties, which fees were earned or
        expenses  were incurred or out of amounts drawn under any form of credit
        support for those Assets and properties;

                (4)     to reimburse a servicer  for any  advances  described in
        clause  (2) above and any  servicing  expenses  described  in clause (3)
        above  which,  in  the  servicer's  good  faith  judgment,  will  not be
        recoverable  from  the  amounts   described  in  those  clauses,   which
        reimbursement  is to be made from amounts  collected on other Assets or,
        if and to the extent so provided by the related  Agreement and described
        in  the  prospectus  supplement,  just  from  that  portion  of  amounts
        collected on other Assets that is otherwise distributable on one or more
        classes of Subordinate Notes or Subordinate Certificates, as applicable,
        if any, remain outstanding, and otherwise any outstanding class of Notes
        or Certificates, as applicable, of the related series;

                (5)     if  and  to  the  extent  described  in  the  prospectus
        supplement, to pay a servicer interest accrued on the advances described
        in clause (2) above and the servicing  expenses  described in clause (3)
        above while those advances and servicing expenses remain outstanding and
        unreimbursed;

                (6)     to reimburse a servicer, the depositor,  or any of their
        respective  directors,  officers,  employees and agents, as the case may
        be, for expenses,  costs and liabilities  incurred by these parties,  as
        and to the extent  described below under  "--Certain  Matters  Regarding
        Servicers, the Master Servicer and the Depositor;"

                (7)     if  and  to  the  extent  described  in  the  prospectus
        supplement, to pay (or to transfer to a separate account for purposes of
        escrowing for the payment of) the trustee's fees;

                (8)     to  reimburse  the  trustee  or any  of  its  directors,
        officers,  employees and agents, as the case may be, for expenses, costs
        and  liabilities  incurred  by  these  parties,  as and  to  the  extent
        described below under "--Certain Matters Regarding the Trustee;"

                (9)     to pay a servicer, as additional servicing compensation,
        interest and investment  income earned in respect of amounts held in the
        Collection Account;

                (10)    to pay the person so entitled  any amounts  deposited in
        the Collection  Account that were identified and applied by the servicer
        as recoveries of Retained Interest;

                (11)    to pay for costs reasonably  incurred in connection with
        the proper management and maintenance of any Mortgaged Property acquired
        for the benefit of  securityholders by foreclosure or by deed in lieu of
        foreclosure  or otherwise,  which  payments are to be made out of income
        received on that property;

                (12)    if one or more  elections  have  been  made to treat the
        issuing entity or designated  portions of the issuing entity as a REMIC,
        to pay any federal,  state or local taxes imposed on the issuing  entity
        or its  assets or  transactions,  as and to the extent  described  under
        "Material Federal Income Tax  Considerations--REMICs--Taxes  That May Be
        Imposed   on  the  REMIC   Pool"  or  in  the   prospectus   supplement,
        respectively;

                                       56



                (13)    to pay for the cost of an independent appraiser or other
        expert in real estate  matters  retained to  determine a fair sale price
        for a  defaulted  mortgage  loan or a property  acquired in respect of a
        mortgage loan in connection  with the  liquidation of that mortgage loan
        or property;

                (14)    to pay  for the  cost of  various  opinions  of  counsel
        obtained   pursuant  to  the  related   Agreement  for  the  benefit  of
        securityholders;

                (15)    to pay for the costs of recording the related  Agreement
        if that recordation materially and beneficially affects the interests of
        securityholders, provided that the payment shall not constitute a waiver
        with respect to the  obligation  of the  Warranting  Party to remedy any
        breach of representation or warranty under the Agreement;

                (16)    to pay the person so entitled  any amounts  deposited in
        the Collection Account in error, including amounts received on any Asset
        after its removal from the issuing  entity whether by reason of purchase
        or  substitution as contemplated  above under  "--Assignment  of Assets;
        Repurchase"  and  "--Representations  and  Warranties;  Repurchases"  or
        otherwise;

                (17)    to make any other  withdrawals  permitted by the related
        Agreement; and

                (18)    to clear and  terminate  the  Collection  Account at the
        termination of the issuing entity.

        OTHER COLLECTION  ACCOUNTS.  If specified in the prospectus  supplement,
the  Agreement  for any  series of Notes or  Certificates,  as  applicable,  may
provide for the establishment and maintenance of a separate  collection  account
into which the servicer  will  deposit on a daily basis,  or any other period as
provided in the related  Agreement,  the amounts  described  under  "--Deposits"
above  for one or more  series  of Notes or  Certificates,  as  applicable.  Any
amounts on deposit in any of these  collection  accounts will be withdrawn  from
these collection accounts and deposited into the appropriate  Collection Account
by a time specified in the prospectus supplement. To the extent specified in the
prospectus  supplement,  any amounts that could be withdrawn from the Collection
Account as described under  "--Withdrawals" above may also be withdrawn from any
of these  collection  accounts.  The  prospectus  supplement  will set forth any
restrictions  for  any  of  these  collection  accounts,   including  investment
restrictions and any restrictions for financial  institutions  with which any of
these collection accounts may be maintained.

        The servicer will  establish and maintain with the indenture  trustee an
account, in the name of the indenture trustee on behalf of the holders of Notes,
into which amounts released from the Collection  Account for distribution to the
holders  of Notes will be  deposited  and from  which all  distributions  to the
holders of Notes will be made.

        COLLECTION AND OTHER SERVICING  PROCEDURES.  The servicer is required to
make reasonable  efforts to collect all scheduled  payments under the Assets and
will follow or cause to be followed those  collection  procedures  that it would
follow with respect to assets that are comparable to the Assets and held for its
own account, provided that those procedures are consistent with

                (1)     the  terms  of the  related  Agreement  and any  related
        hazard  insurance  policy  or  instrument  of  credit  support,  if any,
        included in the related  issuing entity  described in this prospectus or
        under "Description of Credit Support,"

                (2)     applicable law and

                                       57



                (3)     the  general   servicing   standard   specified  in  the
        prospectus  supplement  or, if no standard is so  specified,  its normal
        servicing practices (in either case, the "Servicing Standard").

In  connection,  the servicer  will be permitted in its  discretion to waive any
late  payment  charge or penalty  interest  in  respect of a late  payment on an
Asset.

        Each servicer will also be required to perform other customary functions
of a servicer of  comparable  assets,  including  maintaining  hazard  insurance
policies as described in this prospectus and in any prospectus  supplement,  and
filing and settling  claims  under these  policies;  maintaining,  to the extent
required by the  Agreement,  escrow or  impoundment  accounts of  borrowers  for
payment of taxes,  insurance and other items required to be paid by any borrower
pursuant to the terms of the Assets;  processing assumptions or substitutions in
those cases where the  servicer  has  determined  not to enforce any  applicable
due-on-sale clause;  attempting to cure delinquencies;  supervising foreclosures
or repossessions;  inspecting and managing Mortgaged  Properties or manufactured
homes under some circumstances;  and maintaining  accounting records relating to
the  Assets.  The  servicer  or any other  entity  specified  in the  prospectus
supplement  will be  responsible  for filing and  settling  claims in respect of
particular  Assets  under  any  applicable  instrument  of credit  support.  See
"Description of Credit Support."

        The servicer  may agree to modify,  waive or amend any term of any Asset
in a manner consistent with the Servicing  Standard so long as the modification,
waiver or  amendment  will not (1) affect the amount or timing of any  scheduled
payments  of  principal  or  interest  on the  Asset  or  (2)  in its  judgment,
materially  impair the security for the Asset or reduce the likelihood of timely
payment  of  amounts  due on the  Asset.  The  servicer  also  may  agree to any
modification,  waiver or  amendment  that would so affect or impair the payments
on, or the security for, an Asset if (1) in its judgment,  a material default on
the Asset has occurred or a payment default is reasonably foreseeable and (2) in
its judgment,  that  modification,  waiver or amendment is reasonably  likely to
produce a greater  recovery  with respect to the Asset on a present  value basis
than would liquidation. In the event of any modification, waiver or amendment of
any Asset,  the  servicer  will furnish a copy of that  modification,  waiver or
amendment to the trustee (or its custodian).

        In the case of  Multifamily,  Commercial or Mixed-Use  Mortgage Loans, a
borrower's  failure  to make  required  mortgage  loan  payments  may mean  that
operating  income is  insufficient  to service the  mortgage  loan debt,  or may
reflect the  diversion of that income from the  servicing  of the mortgage  loan
debt.  In addition,  a borrower  under a  Multifamily,  Commercial  or Mixed-Use
Mortgage  Loan that is unable to make  mortgage loan payments may also be unable
to make timely  payment of all  required  taxes and  otherwise  to maintain  and
insure the related Mortgaged Property. In general, the servicer will be required
to monitor any  Multifamily,  Commercial  or Mixed-Use  Mortgage Loan that is in
default,  evaluate  whether the causes of the default  can be  corrected  over a
reasonable  period  without  significant  impairment  of the  value  of  related
Mortgaged Property,  initiate corrective action in cooperation with the borrower
if cure is likely,  inspect the related Mortgaged  Property and take those other
actions as are consistent with the related  Agreement.  A significant  period of
time may elapse  before the  servicer is able to assess the success of servicer,
can make the initial  determination of appropriate action,  evaluate the success
of corrective action,  develop  additional  initiatives,  institute  foreclosure
proceedings  and  actually  foreclose  may vary  considerably  depending  on the
particular  Multifamily,  Commercial  or Mixed-Use  Mortgage  Loan,  the related
Mortgaged Property,  the borrower, the presence of an acceptable party to assume
the  mortgage  loan and the laws of the  jurisdiction  in  which  the  Mortgaged
Property is located.

                                       58



        REALIZATION UPON DEFAULTED ASSETS

        Generally,  the  servicer  is  required  to monitor any Asset that is in
default,  initiate corrective action in cooperation with the borrower if cure is
likely,  inspect the Asset and take any other actions as are consistent with the
Servicing Standard.  A significant period of time may elapse before the servicer
is able to  assess  the  success  of that  corrective  action  or the  need  for
additional initiatives.

        Any Agreement relating to an issuing entity that includes mortgage loans
or  contracts  may grant to the  servicer  and/or  the holder or holders of some
classes of Notes or  Certificates,  as  applicable,  a right of first refusal to
purchase from the issuing entity at a predetermined  purchase price any mortgage
loan or contract as to which a specified number of scheduled  payments under the
Agreement are delinquent. Any right of first refusal granted to the holder of an
Offered Security will be described in the prospectus supplement.  The prospectus
supplement  will also  describe any similar  right  granted to any person if the
predetermined  purchase  price is less than the Purchase Price  described  above
under "--Representations and Warranties; Repurchases."

        If specified  in the  prospectus  supplement,  the servicer may offer to
sell  any  defaulted  mortgage  loan  or  contract  described  in the  preceding
paragraph  and not  otherwise  purchased  by any person  having a right of first
refusal with respect to that  defaulted  mortgage loan or contract,  if and when
the servicer determines,  consistent with the Servicing Standard, so that a sale
would produce a greater recovery on a present value basis than would liquidation
through foreclosure,  repossession or similar proceedings. The related Agreement
will provide that any offering be made in a commercially reasonable manner for a
specified period and that the servicer accept the highest cash bid received from
any  person   (including   itself,   an   affiliate   of  the  servicer  or  any
securityholder)  that constitutes a fair price for that defaulted  mortgage loan
or contract. If there is no bid that is determined to be fair, the servicer will
proceed with respect to that  defaulted  mortgage  loan or contract as described
below. Any bid in an amount at least equal to the Purchase Price described above
under  "--Representations  and  Warranties;  Repurchases"  will in all  cases be
deemed fair.

        The  servicer,  on  behalf  of the  trustee,  may at any time  institute
foreclosure  proceedings,  exercise any power of sale contained in any mortgage,
obtain a deed in lieu of foreclosure,  or otherwise acquire title to a Mortgaged
Property  securing a mortgage  loan by operation of law or otherwise  and may at
any time  repossess  and realize upon any  manufactured  home, if that action is
consistent  with the  Servicing  Standard and a default on that mortgage loan or
contract has occurred or, in the servicer's judgment, is imminent.

        If title to any Mortgaged  Property is acquired by an issuing  entity as
to which a REMIC election has been made, the servicer,  on behalf of the issuing
entity,  will be required to sell the Mortgaged Property within three years from
the close of the calendar year of acquisition,  unless (1) the Internal  Revenue
Service  grants an  extension  of time to sell that  property or (2) the trustee
receives an opinion of independent counsel to the effect that the holding of the
property  by the issuing  entity  longer than three years after the close of the
calendar year of its  acquisition  will not result in the imposition of a tax on
the  issuing  entity or cause the  issuing  entity to fail to qualify as a REMIC
under the Code at any time that any Notes or  Certificates,  as applicable,  are
outstanding.  Subject to the  foregoing,  the  servicer  will be required to (A)
solicit  bids for any  Mortgaged  Property so acquired in that manner as will be
reasonably  likely to realize a fair price for that  property and (B) accept the
first (and, if multiple bids are contemporaneously  received,  the highest) cash
bid received from any person that constitutes a fair price.

        The  limitations   imposed  by  the  related  Agreement  and  the  REMIC
provisions  of the  Code (if a REMIC  election  has  been  made for the  related
issuing entity) on the ownership and

                                       59



management of any Mortgaged  Property  acquired on behalf of the issuing  entity
may  result  in the  recovery  of an  amount  less than the  amount  that  would
otherwise be recovered.

        If recovery on a defaulted Asset under any related  instrument of credit
support is not available,  the servicer nevertheless will be obligated to follow
or cause to be  followed  those  normal  practices  and  procedures  as it deems
necessary or advisable to realize upon the defaulted  Asset.  If the proceeds of
any  liquidation of the property  securing the defaulted Asset are less than the
outstanding  principal  balance of the defaulted Asset plus interest  accrued on
the defaulted  Asset at the applicable  interest rate,  plus the total amount of
expenses incurred by the servicer in connection with those proceedings and which
are reimbursable under the Agreement,  the issuing entity will realize a loss in
the amount of that  difference.  The  servicer  will be  entitled to withdraw or
cause  to be  withdrawn  from  the  Collection  Account  out of the  Liquidation
Proceeds  recovered on any defaulted  Asset,  before the  distribution  of those
Liquidation  Proceeds  to  securityholders,   amounts  representing  its  normal
servicing compensation on the Security, unreimbursed servicing expenses incurred
with respect to the Asset and any unreimbursed  advances of delinquent  payments
made with respect to the Asset.

        With respect to a  Multifamily  Mortgage  Loan,  the market value of any
property obtained in foreclosure or by deed in lieu of foreclosure will be based
substantially on the operating income obtained by renting the dwelling units. As
a default on a  Multifamily  Mortgage  Loan is likely to have  occurred  because
operating income, net of expenses, is insufficient to make debt service payments
on the  mortgage  loan,  it can be  anticipated  that  the  market  value of the
property will be less than anticipated when the mortgage loan was originated. To
the extent that equity does not cushion the loss in market value and the loss is
not covered by other credit  support,  a loss may be  experienced by the related
issuing entity.

        If any  property  securing a defaulted  Asset is damaged the servicer is
not required to expend its own funds to restore the damaged  property  unless it
determines (1) that restoration will increase the proceeds to securityholders on
liquidation  of the Asset after  reimbursement  of the servicer for its expenses
and (2) that its  expenses  will be  recoverable  by it from  related  Insurance
Proceeds or Liquidation Proceeds.

        The pooling and servicing  agreement will require the trustee, if it has
not received a distribution for any Mortgage  Security or Agency Security by the
fifth business day after the date on which that distribution was due and payable
pursuant  to the  terms of that  Agency  Security,  to  request  the  issuer  or
guarantor,  if any, of that  Mortgage  Security or Agency  Security to make that
payment as promptly  as possible  and  legally  permitted  to take legal  action
against  that issuer or  guarantor as the trustee  deems  appropriate  under the
circumstances,  including the prosecution of any claims in connection therewith.
The  reasonable  legal fees and expenses  incurred by the trustee in  connection
with the  prosecution of this legal action will be  reimbursable  to the trustee
out of the  proceeds of that  action and will be retained by the trustee  before
the  deposit  of any  remaining  proceeds  in  the  Collection  Account  pending
distribution of the Collection Account to securityholders of the related series.
If the proceeds of any legal action are  insufficient  to reimburse  the trustee
for its legal fees and  expenses,  the trustee will be entitled to withdraw from
the Collection  Account an amount equal to its expenses,  and the issuing entity
may realize a loss in that amount.

        As servicer of the Assets, a servicer,  on behalf of itself, the trustee
and  the  securityholders,  will  present  claims  to the  borrower  under  each
instrument  of credit  support,  and will  take  those  reasonable  steps as are
necessary to receive payment or to permit  recovery under these  instruments for
defaulted Assets.

        If a servicer or its designee  recovers payments under any instrument of
credit  support  for any  defaulted  Assets,  the  servicer  will be entitled to
withdraw or cause to be withdrawn from the

                                       60



Collection Account out of those proceeds,  before distribution of the Collection
Account  to   securityholders,   amounts   representing   its  normal  servicing
compensation on that Asset,  unreimbursed  servicing  expenses  incurred for the
Asset and any unreimbursed  advances of delinquent payments made with respect to
the Asset. See "Hazard Insurance Policies" and "Description of Credit Support."

        HAZARD INSURANCE POLICIES

        MORTGAGE LOANS. Generally, each Agreement for an issuing entity composed
of  mortgage  loans will  require  the  servicer  to cause the  borrower on each
mortgage loan to maintain a hazard insurance  policy  (including flood insurance
coverage,  if  obtainable,  to the extent the property is located in a federally
designated flood area, in an amount as is required under applicable  guidelines)
providing for the level of coverage that is required under the related  Mortgage
or, if any Mortgage  permits its holder to dictate to the borrower the insurance
coverage to be maintained on the related Mortgaged  Property,  then the level of
coverage that is consistent with the Servicing  Standard.  That coverage will be
in general in an amount equal to the lesser of the  principal  balance  owing on
that  mortgage  loan  (but  not less  than the  amount  necessary  to avoid  the
application of any co-insurance clause contained in the hazard insurance policy)
and the  amount  necessary  to fully  compensate  for any  damage or loss to the
improvements on the Mortgaged  Property on a replacement cost basis or any other
amount  specified in the prospectus  supplement.  The ability of the servicer to
assure that hazard insurance proceeds are appropriately applied may be dependent
upon its being named as an additional  insured under any hazard insurance policy
and under any other  insurance  policy  referred to below, or upon the extent to
which  information  in this  regard  is  furnished  by  borrowers.  All  amounts
collected by the servicer under any of these policies  (except for amounts to be
applied to the  restoration  or repair of the Mortgaged  Property or released to
the borrower in accordance  with the  servicer's  normal  servicing  procedures,
subject to the terms and  conditions of the related  Mortgage and mortgage note)
will be  deposited  in the  Collection  Account in  accordance  with the related
Agreement.

        The Agreement  may provide that the servicer may satisfy its  obligation
to cause each borrower to maintain a hazard  insurance  policy by the servicer's
maintaining  a blanket  policy  insuring  against  hazard losses on the mortgage
loans. If the blanket policy contains a deductible  clause, the servicer will be
required to deposit in the  Collection  Account from its own funds all sums that
would have been deposited in the Collection Account but for that clause.

        In general,  the  standard  form of fire and  extended  coverage  policy
covers physical damage to or destruction of the  improvements of the property by
fire,  lightning,  explosion,  smoke,  windstorm and hail, and riot,  strike and
civil  commotion,  subject to the conditions  and  exclusions  specified in each
policy.   Although  the  policies   relating  to  the  mortgage  loans  will  be
underwritten by different insurers under different state laws in accordance with
different applicable state forms, and therefore will not contain identical terms
and conditions, the basic terms of the policies are dictated by respective state
laws,  and most of these  policies  typically do not cover any  physical  damage
resulting  from  war,  revolution,   governmental  actions,   floods  and  other
water-related  causes,  earth movement  (including  earthquakes,  landslides and
mudflows), wet or dry rot, vermin, domestic animals and other kinds of uninsured
risks.

        The hazard insurance policies covering the Mortgaged Properties securing
the mortgage  loans will typically  contain a coinsurance  clause that in effect
requires the insured at all times to carry  insurance of a specified  percentage
(generally 80% to 90%) of the full replacement  value of the improvements on the
property  to recover  the full  amount of any  partial  loss.  If the  insured's
coverage falls below this specified percentage, the coinsurance clause generally
provides  that the  insurer's  liability  in the event of partial  loss does not
exceed the lesser of (1) the replacement cost of the improvements  less physical
depreciation  and (2) that  proportion  of the loss as the  amount of

                                       61



insurance carried bears to the specified percentage of the full replacement cost
of those improvements.

        Each  Agreement for an issuing  entity  composed of mortgage  loans will
require the servicer to cause the borrower on each mortgage loan to maintain all
other  insurance  coverage for the related  Mortgaged  Property as is consistent
with  the  terms of the  related  Mortgage  and the  Servicing  Standard,  which
insurance  may  typically  include  flood  insurance  (if the related  Mortgaged
Property was located at the time of origination in a federally  designated flood
area).

        Any cost incurred by the servicer in  maintaining  any insurance  policy
will be added to the amount owing under the mortgage loan where the terms of the
mortgage loan so permit; provided,  however, that the addition of that cost will
not be taken into account for purposes of  calculating  the  distribution  to be
made to  securityholders.  Those costs may be recovered by the servicer from the
Collection Account, with interest, as provided by the Agreement.

        Under the terms of the  mortgage  loans,  borrowers  will  generally  be
required  to  present  claims  to  insurers  under  hazard  insurance   policies
maintained on the related Mortgaged  Properties.  The servicer, on behalf of the
trustee and  securityholders,  is  obligated to present or cause to be presented
claims under any blanket  insurance  policy  insuring  against  hazard losses on
Mortgaged  Properties securing the mortgage loans.  However,  the ability of the
servicer to present or cause to be presented  those claims is dependent upon the
extent to which  information  in this  regard is  furnished  to the  servicer by
borrowers.

        OTHER HAZARD-RELATED INSURANCE; LIABILITY INSURANCE

        With respect to Multifamily Loans, certain additional insurance policies
may be required with respect to the related Multifamily  Property;  for example,
general  liability  insurance  for bodily  injury or death and  property  damage
occurring on the property or the adjoining  streets and sidewalks,  steam boiler
coverage where a steam boiler or other pressure vessel is in operation, interest
coverage  insurance,  and rent loss insurance to cover  operating  income losses
following  damage or  destruction of the mortgaged  property.  With respect to a
series for which  Multifamily  Loans are  included  in the issuing  entity,  the
prospectus  supplement will specify the required types and amounts of additional
insurance  and describe the general  terms of the  insurance  and  conditions to
payment thereunder.

        CONTRACTS.  Generally,  the terms of the agreement for an issuing entity
composed of contracts  will  require the servicer to maintain for each  contract
one or more hazard  insurance  policies  that  provide,  at a minimum,  the same
coverage as a standard form fire and extended coverage  insurance policy that is
customary  for  manufactured  housing,  issued by a company  authorized to issue
those policies in the state in which the manufactured home is located, and in an
amount that is not less than the maximum  insurable  value of that  manufactured
home or the  principal  balance due from the  borrower on the related  contract,
whichever is less;  provided,  however,  that the amount of coverage provided by
each hazard  insurance policy must be sufficient to avoid the application of any
co-insurance clause contained therein.  When a manufactured home's location was,
at the  time  of  origination  of  the  related  contract,  within  a  federally
designated special flood hazard area, the servicer must cause flood insurance to
be  maintained,  which  coverage  must be at least equal to the  minimum  amount
specified  in the  preceding  sentence or any lesser  amount as may be available
under the federal flood insurance  program.  Each hazard insurance policy caused
to be  maintained  by the servicer  must contain a standard loss payee clause in
favor of the servicer  and its  successors  and  assigns.  If any borrower is in
default in the payment of premiums on its hazard  insurance  policy or policies,
the  servicer  must  pay  those  premiums  out of its  own  funds,  and  may add
separately  the  premiums  to  the  borrower's  obligation  as  provided  by the
contract, but may not add the premiums to the remaining principal balance of the
contract.

                                       62



        The  servicer  may  maintain,  in  lieu  of  causing  individual  hazard
insurance  policies  to be  maintained  for  each  manufactured  home,  and must
maintain,  to the extent that the related contract does not require the borrower
to maintain a hazard insurance policy for the related  manufactured home, one or
more blanket insurance  policies  covering losses on the borrower's  interest in
the contracts  resulting from the absence or insufficiency of individual  hazard
insurance policies. The servicer must pay the premium for that blanket policy on
the basis described  therein and must pay any deductible amount for claims under
that policy relating to the contracts.

        FHA INSURANCE AND VA GUARANTEES

        FHA loans  will be insured by the FHA as  authorized  under the  Housing
Act.  Some FHA loans will be insured  under  various FHA programs  including the
standard FHA 203(b)  program to finance the  acquisition  of one- to four-family
housing units, the FHA 245 graduated  payment mortgage program and the FHA Title
I Program.  These  programs  generally  limit the principal  amount and interest
rates of the mortgage  loans  insured.  The  prospectus  supplement for Notes or
Certificates,  as applicable,  of each series evidencing interests in an issuing
entity including FHA loans will set forth additional  information  regarding the
regulations governing the applicable FHA insurance programs. Except as otherwise
specified in the prospectus  supplement,  the following  describes FHA insurance
programs and regulations as generally in effect for FHA loans.

        The insurance  premiums for FHA loans are collected by lenders  approved
by the  Department of Housing and Urban  Development  ("HUD") or by the servicer
and are paid to the FHA. The regulations  governing FHA  single-family  mortgage
insurance  programs  provide that  insurance  benefits  are payable  either upon
foreclosure (or other acquisition of possession) and conveyance of the mortgaged
premises to the United  States of America or upon  assignment  of the  defaulted
loan to the United States of America.  For a defaulted FHA loan, the servicer is
limited  in  its  ability  to  initiate  foreclosure  proceedings.  When  it  is
determined,  either  by  the  servicer  or  HUD,  that  default  was  caused  by
circumstances beyond the borrower's control, the servicer is expected to make an
effort to avoid  foreclosure by entering,  if feasible,  into one of a number of
available forms of forbearance plans with the borrower.  Those plans may involve
the reduction or suspension of regular mortgage payments for a specified period,
with those  payments to be made on or before the maturity  date of the mortgage,
or the  recasting  of payments  due under the  mortgage up to or, other than FHA
loans  originated  under the FHA Title I Program,  beyond the maturity  date. In
addition,  when a default caused by those  circumstances is accompanied by other
criteria,  HUD may provide relief by making  payments to the servicer in partial
or full satisfaction of amounts due under the FHA loan (which payments are to be
repaid by the borrower to HUD) or by accepting  assignment  of the loan from the
servicer. With some exceptions, at least three full monthly installments must be
due and unpaid  under the FHA loan,  and HUD must have  rejected any request for
relief  from  the  borrower   before  the  servicer  may  initiate   foreclosure
proceedings.

        HUD has the option, in most cases, to pay insurance claims in cash or in
debentures issued by HUD.  Currently,  claims are being paid in cash, and claims
have  not  been  paid  in  debentures  since  1965.  HUD  debentures  issued  in
satisfaction  of FHA  insurance  claims  bear  interest  at the  applicable  HUD
debentures interest rate. To the extent specified in the prospectus  supplement,
the  servicer of each single  family FHA loan will be  obligated to purchase any
debenture  issued in  satisfaction  of that FHA loan upon  default for an amount
equal to the principal amount of that debenture.

        Other  than in  relation  to the FHA  Title I  Program,  the  amount  of
insurance  benefits  generally  paid by the FHA is  equal to the  entire  unpaid
principal  amount of the  defaulted  FHA loan adjusted to reimburse the servicer
for some of its costs and expenses and to deduct amounts received or retained by
the servicer after default.  When entitlement to insurance benefits results from
foreclosure  (or other  acquisition  of  possession)  and conveyance to HUD, the
servicer is compensated for no more than  two-thirds of its  foreclosure  costs,
and is  compensated  for  interest

                                       63



accrued  and unpaid  before  that date but in general  only to the extent it was
allowed  pursuant to a forbearance  plan approved by HUD.  When  entitlement  to
insurance benefits results from assignment of the FHA loan to HUD, the insurance
payment  includes  full  compensation  for  interest  accrued  and unpaid to the
assignment date. The insurance payment itself,  upon foreclosure of an FHA loan,
bears  interest  from a date 30 days  after  the  borrower's  first  uncorrected
failure to perform any  obligation  to make any  payment due under the  mortgage
and, upon assignment,  from the date of assignment to the date of payment of the
claim,  in each case at the same interest rate as the  applicable  HUD debenture
interest rate as described above.

        VA loans will be partially  guaranteed by the VA under the  Serviceman's
Readjustment Act (a "VA Guaranty Policy"). For a defaulted VA loan, the servicer
is, absent  exceptional  circumstances,  authorized to announce its intention to
foreclose  only when the default has continued for three  months.  Generally,  a
claim  for  the  guarantee  is  submitted  after  liquidation  of the  Mortgaged
Property.

        The amount  payable under the guarantee will be the percentage of the VA
loan  originally  guaranteed  applied  to  indebtedness  outstanding  as of  the
applicable date of computation  specified in the VA regulations.  Payments under
the  guarantee  will be equal to the  unpaid  principal  amount of that VA loan,
interest  accrued on the unpaid balance of that VA loan to the appropriate  date
of computation and limited  expenses of the mortgagee,  but in each case only to
the extent that those amounts have not been recovered through liquidation of the
Mortgaged  Property.  The amount  payable  under the  guarantee  may in no event
exceed the amount of the original guarantee.

        ENVIRONMENTAL INSURANCE

        If  specified  in the  applicable  prospectus  supplement,  the trust or
trustee  will be the  beneficiary,  for the benefit of the  securityholders,  of
insurance policies ("Environmental Policies") providing limited coverage against
certain  environmental  risks with respect to the mortgaged  properties securing
certain Commercial, Multifamily and Mixed-Use Mortgage Loans. Subject to various
exceptions and  exclusions  (including  asbestos and lead paint),  Environmental
Policies will generally  cover losses,  clean-up costs,  third-party  claims and
legal  expenses  up to  pre-determined  limits.  Subject  to  the  terms  of the
applicable policy, if a Mortgaged Property securing a covered loan is subject to
environmental  contamination,  in the  event  of  default  by the  borrower  the
outstanding  principal  balance  of the loan,  plus  accrued  interest,  will be
payable under the applicable Environmental Policy.

        FIDELITY BONDS AND ERRORS AND OMISSIONS INSURANCE

        Each  Agreement  will require  that the servicer  obtain and maintain in
effect a fidelity bond or similar form of insurance  coverage (which may provide
blanket  coverage) or any combination of these insuring  against loss occasioned
by fraud, theft or other intentional  misconduct of the officers,  employees and
agents of the  servicer.  The  related  Agreement  will  allow the  servicer  to
self-insure against loss occasioned by the errors and omissions of the officers,
employees  and agents of the  servicer so long as the  criteria set forth in the
Agreement are met.

        DUE-ON-SALE CLAUSES

        The  mortgage  loans may contain  clauses  requiring  the consent of the
mortgagee to any sale or other transfer of the related  Mortgaged  Property,  or
due-on-sale  clauses  entitling  the  mortgagee  to  accelerate  payment  of the
mortgage loan upon any sale,  transfer or  conveyance  of the related  Mortgaged
Property.  The servicer will  generally  enforce any  due-on-sale  clause to the
extent  it has  knowledge  of  the  conveyance  or  proposed  conveyance  of the
underlying  Mortgaged Property and it is entitled to do so under applicable law;
provided, however, that the servicer will not take any action in relation to the
enforcement of any due-on-sale clause that would:

                                       64



        o   adversely  affect  or  jeopardize   coverage  under  any  applicable
            insurance policy or

        o   materially  increase  the risk of  default  or  delinquency  on,  or
            materially impair the security for, that mortgage loan.

Any  fee  collected  by or on  behalf  of the  servicer  for  entering  into  an
assumption  agreement  will be  retained  by or on  behalf  of the  servicer  as
additional  servicing  compensation.  See  "Certain  Legal  Aspects of  Mortgage
Loans--Due-on-Sale Clauses."

        The  contracts  may also contain  clauses  requiring  the consent of the
mortgagee to any sale or other transfer of the related  mortgaged  property,  or
due-on-sale clauses. The servicer will generally permit that transfer so long as
the transferee satisfies the servicer's then applicable  underwriting standards.
The purpose of those  transfers is often to avoid a default by the  transferring
borrower.

        RETAINED INTEREST; SERVICING COMPENSATION AND PAYMENT OF EXPENSES

        The  prospectus  supplement  for a series of Notes or  Certificates,  as
applicable,  will specify  whether  there will be any  Retained  Interest in the
Assets,  and, if so, the initial  owner of this  Retained  Interest.  If so, the
Retained  Interest  will be  established  on a  loan-by-loan  basis  and will be
specified on an exhibit to the related  Agreement.  A "Retained  Interest" in an
Asset  represents a specified  portion of the interest payable on the Asset. The
Retained  Interest will be deducted from borrower  payments as received and will
not be part of the related issuing entity.

        The servicer's  primary servicing  compensation for a series of Notes or
Certificates,  as  applicable,  will come from the  periodic  payment to it of a
portion of the interest  payment on each Asset or any other amount  specified in
the prospectus supplement.  Since any Retained Interest and a servicer's primary
compensation  are  percentages  of the  principal  balance of each Asset,  those
amounts will decrease in accordance  with the  amortization  of the Assets.  The
prospectus  supplement  for a series of Notes or  Certificates,  as  applicable,
evidencing  interests  in an issuing  entity  that  includes  mortgage  loans or
contracts may provide that, as additional compensation,  the servicer may retain
all or a portion of assumption fees,  modification fees, late payment charges or
Prepayment  Premiums  collected  from borrowers and any interest or other income
that may be  earned  on funds  held in the  Collection  Account  or any  account
established by a servicer pursuant to the Agreement.

        The servicer may, to the extent  provided in the prospectus  supplement,
pay from its servicing  compensation  expenses  incurred in connection  with its
servicing  and  managing  of the  Assets,  including  payment  of the  fees  and
disbursements  of the trustee and independent  accountants,  payment of expenses
incurred in connection with  distributions and reports to  securityholders,  and
payment of any other expenses described in the prospectus supplement. Some other
expenses, including expenses relating to defaults and liquidations on the Assets
and, to the extent so provided in the prospectus  supplement,  interest on these
expenses at the rate specified in the prospectus  supplement may be borne by the
issuing entity.

        If and to the extent provided in the prospectus supplement, the servicer
may be  required  to apply a portion  of the  servicing  compensation  otherwise
payable to it in respect of any Due Period to interest shortfalls resulting from
the voluntary prepayment of any Assets in the related issuing entity during that
period before their due dates.

        EVIDENCE AS TO COMPLIANCE

        Each  pooling and  servicing  agreement  and  servicing  agreement  will
provide that on or before a specified date in March of each year, beginning with
the first  year  after the year in which

                                       65



the cut-off date occurs,  each party responsible for the servicing function will
provide to the depositor and the trustee a report on an assessment of compliance
with the minimum servicing criteria established in Item 1122(a) of Regulation AB
(the "AB  Servicing  Criteria").  The AB  Servicing  Criteria  include  specific
criteria relating to the following areas: general servicing considerations, cash
collection and  administration,  investor  remittances  and reporting,  and pool
asset  administration.  Such report will indicate that the AB Servicing Criteria
were used to test  compliance  on a  platform  level  basis and will set out any
material instances of noncompliance.

        Each pooling and servicing  agreement and servicing  agreement will also
provide that the each party responsible for the servicing  function will deliver
along with its report on assessment of compliance,  an attestation report from a
firm of independent  public accountants on the assessment of compliance with the
AB Servicing Criteria.

        Each pooling and servicing  agreement and servicing  agreement will also
provide for delivery to the trustee,  on or before a specified  date in March of
each  year,  of a separate  annual  statement  of  compliance  from each  entity
responsible for the servicing function to the effect that, to the best knowledge
of the signing officer,  the servicer has fulfilled in all material respects its
obligations  under the pooling and  servicing  agreement or servicing  agreement
throughout  the preceding  year or, if there has been a material  failure in the
fulfillment of any obligation,  the statement shall specify such failure and the
nature and status  thereof.  This  statement  may be  provided  as a single form
making  the  required  statements  as to more  than one  pooling  and  servicing
agreement or servicing agreement.

        Copies of the annual  reports of assessment of  compliance,  attestation
reports, and statements of compliance may be obtained by securityholders without
charge upon written request to the master servicer or trustee.  These items will
be filed with the issuing  entity's  annual  report on Form 10-K,  to the extent
required under Regulation AB.

        CERTAIN  MATTERS  REGARDING  SERVICERS,  THE  MASTER  SERVICER  AND  THE
        DEPOSITOR

        The servicer or master  servicer  under each  Agreement will be named in
the prospectus  supplement.  The entities serving as servicer or master servicer
may  be  affiliates  of  the  depositor  and  may  have  other  normal  business
relationships with the depositor or the depositor's  affiliates.  If applicable,
reference in this  prospectus  to the servicer  will also be deemed to be to the
master servicer. Each Agreement will provide, in general, that:

        o       The  servicer may resign from its  obligations  and duties under
                the Agreement  only upon a  determination  that its duties under
                the Agreement are no longer  permissible under applicable law or
                are in material  conflict by reason of  applicable  law with any
                other  activities  carried on by it, the other activities of the
                servicer  so causing  that  conflict  being of a type and nature
                carried  on by the  servicer  at the date of the  Agreement.  No
                resignation  will  become  effective  until  the  trustee  or  a
                successor  servicer has assumed the servicer's  obligations  and
                duties under the Agreement.

        o       Neither any servicer,  the depositor nor any director,  officer,
                employee,  or agent of a servicer or the depositor will be under
                any liability to the related  issuing entity or  securityholders
                for any action taken,  or for refraining  from the taking of any
                action,  in good  faith  pursuant  to the  Agreement;  provided,
                however,  that neither a servicer,  the  depositor nor any other
                person will be protected against any breach of a representation,
                warranty or covenant made in the related  Agreement,  or against
                any liability specifically imposed by the Agreement,  or against
                any  liability  that  would  otherwise  be  imposed by reason of
                willful misfeasance, bad faith or gross


                                       66



                negligence in the performance of obligations or duties under the
                Agreement or by reason of reckless  disregard of obligations and
                duties under the Agreement.

        o       Any servicer, the depositor and any director,  officer, employee
                or agent of a servicer  or the  depositor  will be  entitled  to
                indemnification  by the related  issuing entity and will be held
                harmless  against  any loss,  liability  or expense  incurred in
                connection  with any legal action  relating to the  Agreement or
                the Notes or  Certificates,  as applicable;  provided,  however,
                that that indemnification will not extend to any loss, liability
                or expense

                (1)     specifically  imposed  by that  Agreement  or  otherwise
                        incidental to the  performance of obligations and duties
                        under  the  Agreement,  including,  in  the  case  of  a
                        servicer,  the  prosecution of an enforcement  action in
                        respect of any specific  mortgage loan or mortgage loans
                        or contract or contracts (except as any loss,  liability
                        or expense  will be otherwise  reimbursable  pursuant to
                        that Agreement);

                (2)     incurred   in   connection   with   any   breach   of  a
                        representation,   warranty  or  covenant  made  in  that
                        Agreement;

                (3)     incurred  by reason of  misfeasance,  bad faith or gross
                        negligence in the  performance  of obligations or duties
                        under the Agreement,  or by reason of reckless disregard
                        of those obligations or duties;

                (4)     incurred in  connection  with any violation of any state
                        or federal securities law; or

                (5)     imposed by any taxing authority if that loss,  liability
                        or expense is not specifically  reimbursable pursuant to
                        the terms of the related Agreement.

        o       Neither  any  servicer  nor  the  depositor  will be  under  any
                obligation  to appear in,  prosecute  or defend any legal action
                that is not incidental to its respective  responsibilities under
                the  Agreement  and which in its  opinion  may involve it in any
                expense  or  liability.  Any  servicer  or  the  depositor  may,
                however,  in its  discretion  undertake  any action which it may
                deem  necessary or desirable  with respect to the  Agreement and
                the rights and duties of the  parties to the  Agreement  and the
                interests of the  securityholders  under the Agreement.  In that
                event,  the  legal  expenses  and costs of that  action  and any
                liability  resulting will be expenses,  costs and liabilities of
                the securityholders,  and the servicer or the depositor,  as the
                case may be, will be entitled to be  reimbursed  therefor and to
                charge the Collection Account.

        Any person  into which the  servicer or the  depositor  may be merged or
consolidated,  or any person resulting from any merger or consolidation to which
the  servicer  or the  depositor  is a party,  or any person  succeeding  to the
business of the servicer or the depositor,  may be the successor of the servicer
or the depositor, as the case may be, under the terms of the related Agreement.

        SPECIAL SERVICERS

        If and to the extent specified in the prospectus  supplement,  a special
servicer (a "Special  Servicer") may be a party to the related  Agreement or may
be  appointed by the servicer or another  specified  party to perform  specified
duties in respect of servicing the related  mortgage loans that would  otherwise
be performed by the servicer (for example,  the workout  and/or  foreclosure  of
defaulted  mortgage  loans).  The rights and obligations of any Special servicer
will be specified in

                                       67



the prospectus  supplement,  and the servicer will be liable for the performance
of a Special  servicer only if, and to the extent,  set forth in the  prospectus
supplement.

        EVENTS OF DEFAULT UNDER THE AGREEMENT

        Events of default under the related Agreement will generally include:

        o   any failure by the servicer to distribute or cause to be distributed
            to  securityholders,  or to remit to the trustee for distribution to
            securityholders,  any required  payment that continues after a grace
            period, if any;

        o   any  failure  by the  servicer  duly to  observe  or  perform in any
            material respect any of its other covenants or obligations under the
            Agreement that continues unremedied for 30 days after written notice
            of that failure has been given to the servicer by the trustee or the
            depositor,  or to the  servicer,  the  depositor  and the trustee by
            securityholders  evidencing  not less than 25% of the voting  rights
            for that series;

        o   any breach of a  representation  or  warranty  made by the  servicer
            under the  Agreement  that  materially  and  adversely  affects  the
            interests of securityholders  and which continues  unremedied for 30
            days  after  written  notice of that  breach  has been  given to the
            servicer by the trustee or the  depositor,  or to the servicer,  the
            depositor  and the trustee by the holders of Notes or  Certificates,
            as applicable, evidencing not less than 25% of the voting rights for
            that series; and

        o   some  events of  insolvency,  readjustment  of debt,  marshaling  of
            assets and  liabilities or similar  proceedings and actions by or on
            behalf of the servicer indicating its insolvency or inability to pay
            its obligations.

        Material  variations to the foregoing  events of default  (other than to
shorten cure periods or eliminate notice  requirements) will be specified in the
prospectus supplement.  The trustee will, not later than the later of 60 days or
any other period specified in the prospectus  supplement after the occurrence of
any event  that  constitutes  or,  with  notice or lapse of time or both,  would
constitute  an event of default  and five days after  specific  officers  of the
trustee  become aware of the  occurrence of that event,  transmit by mail to the
depositor  and all  securityholders  of the  applicable  series  notice  of that
occurrence, unless that default has been cured or waived.

        RIGHTS UPON EVENT OF DEFAULT UNDER THE AGREEMENTS

        So long as an event of default  under an Agreement  remains  unremedied,
the  depositor or the trustee  may, and at the  direction of holders of Notes or
Certificates,  as  applicable,  evidencing  not  less  than  51% (or  any  other
percentage specified in the Agreement) of the voting rights for that series, the
trustee will  terminate all of the rights and  obligations of the servicer under
the Agreement and in and to the mortgage  loans (other than as a  securityholder
or as the owner of any Retained Interest), whereupon the trustee will succeed to
all of the  responsibilities,  duties and  liabilities of the servicer under the
Agreement  (except  that if the  trustee is  prohibited  by law from  obligating
itself  to make  advances  regarding  delinquent  Assets,  or if the  prospectus
supplement  so  specifies,  then the trustee will not be obligated to make those
advances)  and will be entitled  to similar  compensation  arrangements.  If the
trustee is unwilling  or unable so to act, it may or, at the written  request of
the holders of Notes or  Certificates,  as applicable,  entitled to at least 51%
(or any other  percentage  specified in the  Agreement) of the voting rights for
that series, it must appoint, or petition a court of competent  jurisdiction for
the appointment of, a loan servicing institution acceptable to the rating agency
with a net worth at the time of that appointment of at least $15,000,000 (or any
other  amount  specified in the  Agreement)  to act as successor to the servicer

                                       68



under the Agreement.  Pending that appointment,  the trustee is obligated to act
in that  capacity.  The trustee and any  successor  servicer  may agree upon the
servicing  compensation  to be paid,  which in no event may be greater  than the
compensation payable to the servicer under the Agreement.

        The holders of Notes or  Certificates,  as applicable,  representing  at
least 66 2/3% (or any other percentage specified in the Agreement) of the voting
rights  allocated  to the  respective  classes  of  Notes  or  Certificates,  as
applicable,  affected  by any event of default  will be  entitled  to waive that
event of  default;  provided,  however,  that an Event of  Default  involving  a
failure to distribute a required payment to securityholders  described in clause
(1) under "Events of Default under the  Agreements" may be waived only by all of
the  securityholders.  Upon any  waiver of an event of  default,  that  event of
default  will cease to exist and will be deemed to have been  remedied for every
purpose under the Agreement.

        No securityholders  will have the right under any Agreement to institute
any proceeding with respect to the Agreement  unless that holder  previously has
given to the trustee  written  notice of default and unless the holders of Notes
or  Certificates,  as  applicable,  evidencing  not less  than 25% (or any other
percentage  specified in the  Agreement)  of the voting rights have made written
request upon the trustee to institute that proceeding in its own name as trustee
under the Agreement and have offered to the trustee  reasonable  indemnity,  and
the trustee for 60 days (or any other number of days specified in the Agreement)
has neglected or refused to institute any proceeding.  The trustee,  however, is
under no  obligation to exercise any of the trusts or powers vested in it by any
Agreement or to make any investigation of matters arising under the Agreement or
to  institute,  conduct  or defend  any  litigation  under the  Agreement  or in
relation to the  Agreement  at the  request,  order or  direction  of any of the
securityholders  covered by that Agreement,  unless those  securityholders  have
offered to the  trustee  reasonable  security  or  indemnity  against the costs,
expenses and liabilities that may be incurred.

        The manner of  determining  the voting  rights of a Security or class or
classes  of Notes or  Certificates,  as  applicable,  will be  specified  in the
Agreement.

        AMENDMENT

        In general,  each Agreement may be amended by the parties to it, without
the  consent  of any  securityholders  covered  by the  Agreement,  to cure  any
ambiguity or mistake;

                (1)     correct,  modify  or  supplement  any  provision  in the
        Agreement  that may be  inconsistent  with any  other  provision  in the
        Agreement or with the prospectus supplement;

                (2)     make any other  provisions  with  respect  to matters or
        questions   arising  under  the  Agreement   that  are  not   materially
        inconsistent with the provisions of the Agreement; or

                (3)     comply  with  any  requirements  imposed  by  the  Code;
        provided  that,  in the case of  clause  (3),  that  amendment  will not
        adversely   affect  in  any  material   respect  the  interests  of  any
        securityholders  covered  by the  Agreement  as  evidenced  either by an
        opinion of  counsel to that  effect or the  delivery  to the  trustee of
        written  notification  from each  rating  agency that  provides,  at the
        request  of the  depositor,  a rating for the  Offered  Notes or Offered
        Certificates,  as  applicable,  of the related series to the effect that
        that amendment or supplement  will not cause that rating agency to lower
        or  withdraw  the  then  current  rating  assigned  to  those  Notes  or
        Certificates, as applicable.

        In general,  each  Agreement may also be amended by the  depositor,  the
servicer,  if any,  and the  trustee,  with the  consent of the  securityholders
affected by the amendment evidencing not

                                       69



less than 51% (or any other percentage specified in the Agreement) of the voting
rights, for any purpose;  provided,  however, no amendment may (1) reduce in any
manner the amount of, or delay the timing of,  payments  received or advanced on
Assets that are required to be distributed  on any Security  without the consent
of the  securityholder or (2) reduce the consent  percentages  described in this
paragraph  without  the  consent  of  all  the  securityholders  covered  by the
Agreement then outstanding. However, for any series of Notes or Certificates, as
applicable,  as to which a REMIC  election is to be made,  the trustee  will not
consent to any amendment of the  Agreement  unless it has first have received an
opinion of independent counsel to the effect that that amendment will not result
in the  imposition  of a tax on the related  issuing  entity or, if  applicable,
cause the related issuing entity to fail to qualify as a REMIC, at any time that
the related Notes or Certificates, as applicable, are outstanding.

        THE TRUSTEE

        The  trustee  under  each  Agreement  will be  named  in the  prospectus
supplement.   The  commercial  bank,  national  banking   association,   banking
corporation or trust company serving as trustee may have a banking  relationship
with the depositor and its affiliates,  with any servicer and its affiliates and
with any master servicer and its affiliates.  To the extent  consistent with its
fiduciary  obligations as trustee, the trustee may delegate its duties to one or
more agents as provided in the Agreement.

        DUTIES OF THE TRUSTEE

        The  trustee  will  make  no  representations  as  to  the  validity  or
sufficiency of any Agreement, the Notes or Certificates,  as applicable,  or any
Asset or related  document and is not  accountable for the use or application by
or on behalf of any  servicer  of any funds paid to the master  servicer  or its
designee in respect of the Notes or Certificates,  as applicable, or the Assets,
or deposited into or withdrawn from the Collection  Account or any other account
by or on behalf of the  servicer.  If no Event of Default  has  occurred  and is
continuing,  the trustee is required to perform only those  duties  specifically
required under the related Agreement,  as applicable.  However,  upon receipt of
the various certificates,  reports or other instruments required to be furnished
to it, the trustee is  required  to examine  those  documents  and to  determine
whether they conform to the requirements of the Agreement.

        If an Event of Default shall occur,  the trustee shall, at the direction
of 51% of the  holders of the  Certificates,  by notice in writing to the master
servicer and to the Depositor,  with a copy to each Rating Agency, terminate all
of the rights and  obligations of the master  servicer in its capacity as Master
Servicer  under the  related  pooling  and  servicing  agreement,  to the extent
permitted by law, and in and to the mortgage loans and the proceeds thereof.  On
or after  the  receipt  by the  master  servicer  of such  written  notice,  all
authority  and power of the master  servicer  with  respect to the  Certificates
(other than as a holder of any  Certificate)  or the mortgage loans or otherwise
including,  without limitation,  the compensation payable to the master servicer
under the related pooling and servicing  agreement,  shall pass to and be vested
in the trustee,  and,  without  limitation,  the trustee shall be authorized and
empowered,  as attorney-in-fact or otherwise,  to execute and deliver, on behalf
of and at the expense of the master  servicer,  any and all  documents and other
instruments  and to do or  accomplish  all  other  acts or things  necessary  or
appropriate  to effect the  purposes of such notice of  termination,  whether to
complete the transfer and  endorsement  or assignment of the mortgage  loans and
related documents, or otherwise.

        To the extent that the costs and expenses of the trustee  related to the
termination of the master  servicer,  appointment of a successor master servicer
or  the  transfer  and  assumption  of  the  master  servicing  by  the  trustee
(including,  without  limitation,  (i) all legal costs and  expenses and all due
diligence  costs and expenses  associated  with an  evaluation  of the potential
termination  of the master  servicer as a result of an event of default and (ii)
all costs and  expenses  associated  with

                                       70



the complete transfer of the master servicing, including all servicing files and
all  servicing  data and the  completion,  correction  or  manipulation  of such
servicing  data as may be required by the successor  master  servicer to correct
any errors or  insufficiencies  in the servicing data or otherwise to enable the
successor  master  servicer to master  service the mortgage  loans in accordance
with the  related  pooling  and  servicing  agreement)  are not fully and timely
reimbursed by the terminated  master servicer,  the trustee shall be entitled to
reimbursement of such costs and expenses from the Distribution Account.

        CERTAIN MATTERS REGARDING THE TRUSTEE

        The trustee and any director,  officer, employee or agent of the trustee
will be entitled to indemnification  out of the Collection Account for any loss,
liability  or  expense  (including  costs and  expenses  of  litigation,  and of
investigation,  counsel fees, damages, judgments and amounts paid in settlement)
incurred in connection with the trustee's

                (1)     enforcing  its rights and  remedies and  protecting  the
        interests of the  securityholders  during the continuance of an Event of
        Default,

                (2)     defending or prosecuting  any legal action in respect of
        the related Agreement or series of Notes or Certificates, as applicable,

                (3)     being the mortgagee of record for the mortgage  loans in
        an issuing  entity and the owner of record  for any  Mortgaged  Property
        acquired in respect thereof for the benefit of securityholders, or

                (4)     acting or  refraining  from  acting in good faith at the
        direction of the holders of the related series of Notes or Certificates,
        as applicable, entitled to not less than 25% (or any other percentage as
        is specified in the related Agreement for any particular  matter) of the
        voting rights for that series;

provided,  however,  that  this  indemnification  will not  extend  to any loss,
liability  or expense  that  constitutes  a specific  liability  of the  trustee
pursuant to the related Agreement, or to any loss, liability or expense incurred
by reason of willful  misfeasance,  bad faith or  negligence  on the part of the
trustee in the performance of its obligations and duties under the Agreement, or
by reason of its reckless  disregard of those  obligations or duties,  or as may
arise from a breach of any  representation,  warranty or covenant of the trustee
made in the Agreement.

        RESIGNATION AND REMOVAL OF THE TRUSTEE

        The trustee may resign at any time, in which event the depositor will be
obligated  to appoint a successor  trustee.  The  depositor  may also remove the
trustee if the trustee  ceases to be eligible to continue  under the pooling and
servicing agreement or if the trustee becomes insolvent.  Upon becoming aware of
the  circumstances,  the  depositor  will be  obligated  to appoint a  successor
trustee.  The  trustee  may  also  be  removed  at any  time by the  holders  of
securities  evidencing not less a majority of the aggregate  undivided interests
(or,  if  applicable,   voting  rights)  in  the  related  issuing  entity.  Any
resignation  or removal of the trustee and  appointment  of a successor  trustee
will not become  effective until  acceptance of the appointment by the successor
trustee.  If the trustee  resigns or is removed by the  depositor,  the expenses
associated  with the change of trustees  will be paid by the former  trustee and
reimbursed from the Distribution  Account.  If the trustee is removed by holders
of  securities,  such holders shall be responsible  for paying any  compensation
payable to a successor trustee,  in excess of the amount paid to the predecessor
trustee.

                                       71



MATERIAL TERMS OF THE INDENTURE

        GENERAL

        The following summary describes the material  provisions that may appear
in each indenture. The prospectus supplement for a series of Notes will describe
any provision of the indenture  relating to that series that materially  differs
from  the  description  of that  provision  contained  in this  prospectus.  The
summaries do not purport to be complete and are subject to, and are qualified by
reference to, all of the  provisions  of the indenture for a series of Notes.  A
form of an indenture has been filed as an exhibit to the Registration  Statement
of which this  prospectus is a part.  The  depositor  will provide a copy of the
indenture (without exhibits) relating to any series of Notes without charge upon
written request of a  securityholder  of that series addressed to ACE Securities
Corp.,  6525 Morrison  Boulevard,  Suite 318,  Charlotte,  North Carolina 28211,
Attention: Evelyn Echevarria.

        EVENTS OF DEFAULT

        Events of  default  under the  indenture  for each  series of Notes will
generally include:

        o   a default for thirty days (or any other number of days  specified in
            the  prospectus  supplement) or more in the payment of any principal
            of or interest on a Note of that series,  to the extent specified in
            the prospectus supplement;

        o   failure  to  perform  any other  covenant  of the  depositor  or the
            issuing entity in the indenture that continues for a period of sixty
            days  (or any  other  number  of days  specified  in the  prospectus
            supplement or the indenture) after notice of the failure is given in
            accordance   with  the   procedures   described  in  the  prospectus
            supplement;

        o   any  representation or warranty made by the depositor or the issuing
            entity  in the  indenture  or in any  certificate  or other  writing
            delivered  pursuant  to the  indenture  or in  connection  with  the
            indenture  with  respect to or  affecting  that  series  having been
            incorrect in a material respect as of the time made, and that breach
            is not  cured  within  sixty  days  (or  any  other  number  of days
            specified in the prospectus  supplement)  after notice of the breach
            is  given  in  accordance  with  the  procedures  described  in  the
            prospectus supplement;

        o   specified   events  of  bankruptcy,   insolvency,   receivership  or
            liquidation of the issuing entity; or

        o   any other event of default  provided  with  respect to Notes of that
            series.

        If an event of  default  with  respect to the Notes of any series at the
time outstanding occurs and is continuing, subject to and in accordance with the
terms of the  indenture,  either  the  indenture  trustee  or the  holders  of a
majority  of the then total  outstanding  amount of the Notes of that series may
declare  the  principal  amount  (or,  if the Notes of that  series are  Accrual
Securities,  that  portion of the  principal  amount as may be  specified in the
terms of that  series,  as provided in the  indenture)  of all the Notes of that
series to be due and  payable  immediately.  That  declaration  may,  under some
circumstances, be rescinded and annulled by the securityholders of a majority in
total outstanding amount of the Notes of that series.

        If,  following  an event of default with respect to any series of Notes,
the Notes of that series have been declared to be due and payable, the indenture
trustee may, in its discretion,

                                       72



notwithstanding   that  acceleration,   elect  to  maintain  possession  of  the
collateral  securing  the  Notes  of  that  series  and  to  continue  to  apply
distributions  on  that  collateral  as if  there  had  been no  declaration  of
acceleration if that collateral  continues to provide  sufficient  funds for the
payment of  principal  of and interest on the Notes of that series as they would
have  become  due if there  had not been  that  declaration.  In  addition,  the
indenture  trustee may not sell or otherwise  liquidate the collateral  securing
the Notes of a series following an event of default, other than a default in the
payment of any  principal or interest on any Note of that series for thirty days
or more, unless

                (1)     the holders of 100% (or any other  percentage  specified
        in the indenture) of the then total  outstanding  amount of the Notes of
        that series consent to that sale;

                (2)     the proceeds of that sale or liquidation  are sufficient
        to pay in full the principal of and accrued interest, due and unpaid, on
        the outstanding Notes of that series at the date of that sale; or

                (3)     the indenture  trustee  determines  that that collateral
        would not be  sufficient on an ongoing basis to make all payments on the
        Notes as those  payments would have become due if the Notes had not been
        declared due and payable,  and the indenture trustee obtains the consent
        of the  holders  of 66 2/3% (or any other  percentage  specified  in the
        indenture)  of the then  total  outstanding  amount of the Notes of that
        series.

        If so specified in the prospectus supplement, only holders of particular
classes of Notes will have the right to declare  the Notes of that  series to be
immediately  due and  payable in the event of a payment  default,  as  described
above, and to exercise the remedies described above.

        If the indenture trustee liquidates the collateral in connection with an
event of default  involving a default  for thirty  days (or any other  number of
days  specified  in the  indenture)  or more in the payment of  principal  of or
interest on the Notes of a series,  the  indenture  provides  that the indenture
trustee  will have a prior lien on the  proceeds of any  liquidation  for unpaid
fees and expenses.  As a result,  upon the  occurrence of that event of default,
the amount available for distribution to the securityholders  would be less than
would otherwise be the case. However,  the indenture trustee may not institute a
proceeding  for  the  enforcement  of  its  lien  except  in  connection  with a
proceeding  for the  enforcement of the lien of the indenture for the benefit of
the securityholders after the occurrence of that event of default.

        To the extent  provided in the prospectus  supplement,  in the event the
principal  of the Notes of a series is declared  due and  payable,  as described
above, the holders of any Notes issued at a discount from par may be entitled to
receive no more than an amount equal to the unpaid principal amount of the Notes
less the amount of the discount that is unamortized.

        Subject to the provisions of the indenture relating to the duties of the
indenture trustee, in case an event of default occurs and continues for a series
of Notes,  the indenture  trustee will be under no obligation to exercise any of
the rights or powers  under the  indenture at the request or direction of any of
the securityholders of that series,  unless those holders offer to the indenture
trustee security or indemnity satisfactory to it against the costs, expenses and
liabilities  that might be  incurred  by it in  complying  with that  request or
direction.  Subject to those provisions for indemnification and some limitations
contained  in the  indenture,  the  holders  of a  majority  of the  then  total
outstanding amount of the Notes of that series will have the right to direct the
time,  method and place of conducting any proceeding for any remedy available to
the  indenture  trustee  or  exercising  any  trust  or power  conferred  on the
indenture trustee with respect to the Notes of that series, and the holders of a
majority of the then total  outstanding  amount of the Notes of that series may,
in some cases, waive any default with respect to the Notes,  except a default in
the  payment of  principal  or interest or a default in respect of a covenant or
provision of the indenture

                                       73



that cannot be modified  without the waiver or consent of all the holders of the
outstanding Notes of that series affected.

        DISCHARGE OF INDENTURE

        The  indenture  will be  discharged,  subject to the  provisions  of the
indenture,  for a series of Notes (except for continuing rights specified in the
indenture)  upon the delivery to the indenture  trustee for  cancellation of all
the Notes of that  series  or,  with some  limitations,  upon  deposit  with the
indenture  trustee  of funds  sufficient  for the  payment in full of all of the
Notes of that series.

        With some limitations, the indenture will provide that, if specified for
the Notes of any series,  the related issuing entity will be discharged from any
and all  obligations  in  respect  of the  Notes  of  that  series  (except  for
obligations  specified  in  the  indenture  including  obligations  relating  to
temporary  Notes and exchange of Notes,  to register the transfer of or exchange
Notes of that series, to replace stolen, lost or mutilated Notes of that series,
to maintain  paying  agencies  and to hold monies for payment in trust) upon the
deposit with the indenture trustee, in trust, of money and/or direct obligations
of or  obligations  guaranteed by the United States of America which through the
payment of interest  and  principal in respect of the Notes in  accordance  with
their terms will provide  money in an amount  sufficient to pay the principal of
and each  installment  of interest  on the Notes of that series on the  maturity
date  for  those  Notes  and any  installment  of  interest  on  those  Notes in
accordance with the terms of the indenture and the Notes of that series.  In the
event of any defeasance and discharge of Notes of that series,  holders of Notes
of that  series  would be able to look only to that money  and/or  those  direct
obligations for payment of principal and interest,  if any, on their Notes until
maturity.

        INDENTURE TRUSTEE'S ANNUAL REPORT

        The indenture  trustee for each series of Notes will be required to mail
each year to all  related  securityholders  a brief  report,  as provided in the
indenture,  relating  to  its  eligibility  and  qualification  to  continue  as
indenture trustee under the related indenture,  any amounts advanced by it under
the indenture, the amount, interest rate and maturity date of indebtedness owing
by that Trust to the applicable  indenture  trustee in its individual  capacity,
the property and funds physically held by the indenture  trustee in its capacity
as  indenture  trustee and any action  taken by it that  materially  affects the
Notes and that has not been previously reported.

        THE INDENTURE TRUSTEE

        The  indenture  trustee for a series of Notes will be  specified  in the
prospectus  supplement.  The indenture  trustee for any series may resign at any
time in accordance with the terms of the indenture, in which event the depositor
or the  appropriate  party  designated  in the  indenture  will be  obligated to
appoint a successor  trustee for that series.  The depositor or the  appropriate
party designated in the indenture may also remove any indenture  trustee if that
indenture  trustee  ceases to be eligible to continue as the  indenture  trustee
under the related indenture,  if that indenture trustee becomes insolvent or for
any  other  grounds  specified  in the  indenture.  In those  circumstances  the
depositor or the appropriate party designated in the indenture will be obligated
to  appoint  a  successor  trustee  for the  applicable  series  of  Notes.  Any
resignation or removal of the indenture  trustee and  appointment of a successor
trustee for any series of Notes does not become  effective  until  acceptance of
the appointment by the successor trustee for that series.

        The  bank or trust  company  serving  as  indenture  trustee  may have a
banking relationship with the depositor or any of its affiliates,  a servicer or
any of its affiliates or the master  servicer or any of its  affiliates.  To the
extent  consistent  with its fiduciary  obligations  as indenture  trustee,  the
indenture  trustee may  delegate its duties to one or more agents as provided in
the indenture and the Agreement.

                                       74



                          DESCRIPTION OF CREDIT SUPPORT

GENERAL

        For any series of Notes or Certificates,  as applicable,  credit support
may be provided  for one or more  classes of the series or the  related  Assets.
Credit support only may be in the form of one or more of the following features:

        o   letters of credit;

        o   Pool Insurance Policies;

        o   special hazard insurance policies;

        o   Bankruptcy Bonds;

        o   guarantees; or

        o   the establishment of one or more reserve funds.

        Alternatively,  the  prospectus  supplement  relating  to  a  series  of
securities  will specify if credit support may be provided by  subordination  of
one or more classes of securities or by  overcollateralization,  in  combination
with or in lieu of any one or more of the instruments set forth above.

        Any form of credit  support may be  structured so as to be drawn upon by
more than one series to the extent described in the prospectus supplement.

        The  coverage  provided by any credit  support  will be described in the
prospectus  supplement.  Generally,  that coverage  will not provide  protection
against  all  risks  of loss  and will not  guarantee  repayment  of the  entire
Security  Balance of the Notes or Certificates,  as applicable,  and interest on
the  Security  Balance.  If losses or  shortfalls  occur that  exceed the amount
covered  by  credit  support  or  that  are  not  covered  by  credit   support,
securityholders will bear their allocable share of deficiencies.  Moreover, if a
form of credit support covers more than one series of Notes or Certificates,  as
applicable (each, a "Covered Trust"),  securityholders  evidencing  interests in
any of those Covered  Trusts will be subject to the risk that the credit support
will be  exhausted  by the claims of other  Covered  Trusts  before that Covered
Trust receiving any of its intended share of that coverage.

        If  credit  support  is  provided  for one or more  classes  of Notes or
Certificates,  as applicable, of a series, or the related Assets, the prospectus
supplement will include a description of

        (a)     the nature and amount of coverage under that credit support,

        (b)     any  conditions to payment under the  prospectus  supplement not
        otherwise described in this prospectus,

        (c)     the conditions (if any) under which the amount of coverage under
        that credit  support may be reduced and under which that credit  support
        may be terminated or replaced and

        (d)     the material provisions relating to that credit support.

                                       75



        Additionally,  the prospectus supplement will set forth information with
respect to the obligor under any financial guaranty insurance policy,  letter of
credit, guarantee or similar instrument of credit support, including

        (1)     a brief description of its principal business activities,

        (2)     its principal place of business,  place of incorporation and the
        jurisdiction under which it is chartered or licensed to do business,

        (3)     if applicable, the identity of regulatory agencies that exercise
        primary jurisdiction over the conduct of its business and

        (4)     its  total  assets,  and  its  stockholders'  or  policyholders'
        surplus,  if  applicable,  as of the date  specified  in the  prospectus
        supplement.

SUBORDINATE SECURITIES

        One or more classes of Notes or Certificates, as applicable, of a series
may  be  Subordinate  Notes  or  Subordinate  Certificates,  as  applicable,  if
specified in the prospectus supplement. The rights of the holders of Subordinate
Notes or Subordinate  Certificates,  as applicable,  to receive distributions of
principal and interest from the Collection Account on any Distribution Date will
be  subordinated  to those  rights  of the  holders  of  Senior  Notes or Senior
Certificates,  as applicable. The subordination of a class may apply only in the
event of (or may be limited to) particular  types of losses or  shortfalls.  The
prospectus  supplement  will set  forth  information  concerning  the  amount of
subordination  of a  class  or  classes  of  Subordinate  Notes  or  Subordinate
Certificates,  as  applicable,  in a series,  the  circumstances  in which  that
subordination  will be applicable and the manner, if any, in which the amount of
subordination will be effected.

CROSS-SUPPORT PROVISIONS

        If the  Assets for a series  are  divided  into  separate  groups,  each
supporting a separate class or classes of Notes or Certificates,  as applicable,
of a  series,  credit  support  may  be  provided  by  cross-support  provisions
requiring that distributions be made on Senior Notes or Senior Certificates,  as
applicable,   evidencing  interests  in  one  group  of  mortgage  loans  before
distributions on Subordinate Notes or Subordinate  Certificates,  as applicable,
evidencing  interests in a different  group of mortgage loans within the issuing
entity.  The prospectus  supplement  for a series that includes a  cross-support
provision will describe the manner and conditions for applying those provisions.

LIMITED GUARANTEE

        If  specified  in the  prospectus  supplement  for a series  of Notes or
Certificates, as applicable, credit enhancement may be provided in the form of a
limited guarantee issued by a guarantor named in the prospectus supplement.  Any
guarantee  specified in the prospectus  supplement,  if any, will be exempt from
registration under the Securities Act.

FINANCIAL GUARANTY INSURANCE POLICY OR SURETY BOND

        Credit  enhancement may be provided in the form of a financial  guaranty
insurance  policy or a surety bond  issued by an insurer  named in the policy or
surety bond, if specified in the prospectus supplement.

                                       76



LETTER OF CREDIT

        Alternative  credit  support for a series of Notes or  Certificates,  as
applicable, may be provided by the issuance of a letter of credit by the bank or
financial  institution  specified in the  prospectus  supplement.  The coverage,
amount and frequency of any reduction in coverage provided by a letter of credit
issued for a series of Notes or Certificates,  as applicable,  will be set forth
in the prospectus supplement relating to that series.

POOL INSURANCE POLICIES

        If specified in the prospectus  supplement relating to a series of Notes
or Certificates,  as applicable,  a pool insurance policy for the mortgage loans
in the related issuing entity will be obtained.  The pool insurance  policy will
cover  any  loss  (subject  to  the  limitations  described  in  the  prospectus
supplement)  by reason of default to the extent a related  mortgage  loan is not
covered by any primary mortgage insurance policy. The amount and principal terms
of any pool insurance coverage will be set forth in the prospectus supplement.

SPECIAL HAZARD INSURANCE POLICIES

        A special hazard  insurance  policy may also be obtained for the related
issuing  entity,  if specified in the prospectus  supplement,  in the amount set
forth in the prospectus  supplement.  The special hazard  insurance policy will,
subject to the  limitations  described  in the  prospectus  supplement,  protect
against loss by reason of damage to Mortgaged  Properties  caused by hazards not
insured  against  under the  standard  form of hazard  insurance  policy for the
respective states, in which the Mortgaged Properties are located. The amount and
principal  terms of any special hazard  insurance  coverage will be set forth in
the prospectus supplement.

BORROWER BANKRUPTCY BOND

        Losses  resulting  from a bankruptcy  proceeding  relating to a borrower
affecting  the  mortgage  loans in an  issuing  entity  for a series of Notes or
Certificates, as applicable, will, if specified in the prospectus supplement, be
covered under a borrower  bankruptcy bond (or any other instrument that will not
result  in a  downgrading  of  the  rating  of the  Notes  or  Certificates,  as
applicable, of a series by the rating agency or agencies that rate that series).
Any borrower  bankruptcy bond or any other  instrument will provide for coverage
in an amount  meeting the criteria of the rating  agency or agencies  rating the
Notes or Certificates,  as applicable,  of the related series, which amount will
be set forth in the prospectus supplement. The amount and principal terms of any
borrower bankruptcy coverage will be set forth in the prospectus supplement.

RESERVE FUNDS

        If so provided  in the  prospectus  supplement  for a series of Notes or
Certificates, as applicable,  deficiencies in amounts otherwise payable on those
Notes  or  Certificates,   as  applicable,  or  specific  classes  of  Notes  or
Certificates,  as  applicable,  will be covered by one or more reserve  funds in
which  cash,  a letter of  credit,  Permitted  Investments,  a demand  note or a
combination  of these will be  deposited,  in the  amounts so  specified  in the
prospectus  supplement.  The reserve  funds for a series may also be funded over
time by  depositing  a  specified  amount of the  distributions  received on the
related Assets as specified in the prospectus supplement.

        Amounts on deposit in any reserve fund for a series,  together  with the
reinvestment  income on these amounts, if any, will be applied for the purposes,
in the manner,  and to the extent  specified  in the  prospectus  supplement.  A
reserve fund may be provided to increase the likelihood

                                       77



of  timely   distributions  of  principal  of  and  interest  on  the  Notes  or
Certificates, as applicable. If specified in the prospectus supplement,  reserve
funds may be established to provide limited  protection  against only some types
of losses and shortfalls.  Following each Distribution Date amounts in a reserve
fund in excess of any amount  required to be  maintained in the reserve fund may
be  released  from the  reserve  fund  under the  conditions  and to the  extent
specified in the  prospectus  supplement  and will not be available  for further
application to the Notes or Certificates, as applicable.

        Money  deposited  in any reserve  funds will be  invested  in  Permitted
Investments, to the extent specified in the prospectus supplement. To the extent
specified in the prospectus  supplement,  any reinvestment  income or other gain
from those  investments  will be credited to the related  reserve  fund for that
series,  and any loss  resulting from those  investments  will be charged to the
reserve  fund.  However,  that income may be payable to any related  servicer or
another  service  provider  or other  entity.  To the  extent  specified  in the
prospectus supplement, the reserve fund, if any, for a series will not be a part
of the issuing entity.

        Additional  information concerning any reserve fund will be set forth in
the prospectus  supplement,  including the initial  balance of the reserve fund,
the balance  required to be maintained in the reserve fund,  the manner in which
the required  balance will decrease over time, the manner of funding the reserve
fund,  the  purposes  for which funds in the reserve fund may be applied to make
distributions to securityholders and use of investment earnings from the reserve
fund, if any.

OVERCOLLATERALIZATION

        If specified in the prospectus supplement,  subordination  provisions of
an issuing entity may be used to accelerate to a limited extent the amortization
of one or more classes of Notes or Certificates, as applicable,  relative to the
amortization of the related Assets. The accelerated  amortization is achieved by
the  application  of excess  interest to the payment of principal of one or more
classes of Notes or  Certificates,  as  applicable.  This  acceleration  feature
creates, for the Assets or groups of Assets, overcollateralization, which is the
excess of the total  principal  balance  of the  related  Assets,  or a group of
related  Assets,  over the principal  balance of the related class or classes of
Notes or  Certificates,  as applicable.  This  acceleration may continue for the
life  of the  related  Security,  or may be  limited.  In the  case  of  limited
acceleration,  once the required level of  overcollateralization is reached, and
subject to the provisions  specified in the prospectus  supplement,  the limited
acceleration  feature may cease, unless necessary to maintain the required level
of overcollateralization.

PRIMARY MORTGAGE INSURANCE POLICIES

        The servicer  will  maintain or cause to be  maintained  with respect to
each mortgage loan, a primary  mortgage  insurance policy in accordance with the
underwriting standards described in the related prospectus supplement.  Although
the terms and conditions of primary mortgage  insurance  policies  differ,  each
primary  mortgage  insurance  policy will generally cover losses up to an amount
equal to the excess of the unpaid principal amount of a defaulted mortgage loan,
plus accrued and unpaid interest thereon and approved expenses, over a specified
percentage of the value of the related mortgaged property.

        As  conditions  to the  filing  or  payment  of a claim  under a primary
mortgage insurance policy, the insured will typically be required,  in the event
of default by the borrower, to:

        o   advance  or  discharge  (a)  hazard  insurance  premiums  and (b) as
            necessary and approved in advance by the insurer, real estate taxes,
            property  protection and  preservation  expenses and foreclosure and
            related costs,

                                       78



        o   in the  event  of any  physical  loss  or  damage  to the  mortgaged
            property,  have the  mortgaged  property  restored  to at least  its
            condition at the effective  date of the primary  mortgage  insurance
            policy, ordinary wear and tear excepted, and

        o   tender to the insurer good and merchantable title to, and possession
            of, the mortgaged property.

                     CERTAIN LEGAL ASPECTS OF MORTGAGE LOANS

        The  following  discussion  contains  summaries,  which are  general  in
nature,  of legal  aspects of loans  secured by  single-family  or  multi-family
residential  properties.  Because these legal aspects are governed  primarily by
applicable state law (which laws may differ substantially), the summaries do not
purport to be complete nor to reflect the laws of any particular  state,  nor to
encompass the laws of all states in which the security for the mortgage loans is
situated.  The  summaries  are  qualified in their  entirety by reference to the
applicable  federal and state laws governing the mortgage loans. In this regard,
the following  discussion  does not fully reflect  federal  regulations  for FHA
loans and VA loans. See "Description of The Issuing  Entities--FHA  Loans and VA
Loans,"  "Description  of the  Agreements--Material  Terms  of the  Pooling  and
Servicing Agreements and Underlying Servicing  Agreements--FHA  Insurance and VA
Guarantees" and "Description of the Issuing Entities--Assets."

GENERAL

        All of the mortgage loans are evidenced by a note or bond and secured by
instruments  granting  a  security  interest  in  real  property  which  may  be
mortgages,  deeds of trust, security deeds or deeds to secure debt, depending on
the prevailing  practice and law in the state in which the Mortgaged Property is
located.  Mortgages,  deeds  of  trust  and  deeds  to  secure  debt are in this
prospectus  collectively  referred to as "mortgages." Any of the foregoing types
of mortgages  will create a lien upon, or grant a title interest in, the subject
property,  the  priority  of which  will  depend on the terms of the  particular
security instrument,  as well as separate,  recorded,  contractual  arrangements
with others holding  interests in the mortgaged  property,  the knowledge of the
parties to that instrument as well as the order of recordation of the instrument
in  the  appropriate  public  recording  office.  However,  recording  does  not
generally  establish priority over governmental claims for real estate taxes and
assessments and other charges imposed under governmental police powers.

TYPES OF MORTGAGE INSTRUMENTS

        A mortgage  either creates a lien against or constitutes a conveyance of
real property between two parties--a  borrower (usually the owner of the subject
property)  and a  mortgagee  (the  lender).  In  contrast,  a deed of trust is a
three-party  instrument,  among a trustor  (the  equivalent  of a  borrower),  a
trustee to whom the  mortgaged  property is  conveyed,  and a  beneficiary  (the
lender) for whose benefit the  conveyance  is made. As used in this  prospectus,
unless the context otherwise  requires,  "borrower" includes the trustor under a
deed of trust and a grantor under a security deed or a deed to secure debt.

        Under a deed of trust,  the borrower  grants the  property,  irrevocably
until the debt is paid, in trust, generally with a power of sale as security for
the indebtedness  evidenced by the related note. A deed to secure debt typically
has two parties.  By executing a deed to secure debt, the grantor  conveys title
to, as opposed  to merely  creating a lien upon,  the  subject  property  to the
grantee until the underlying  debt is repaid,  generally with a power of sale as
security for the indebtedness evidenced by the related mortgage note.

                                       79



        In case the borrower under a mortgage is a land trust, there would be an
additional  party  because legal title to the property is held by a land trustee
under a land trust agreement for the benefit of the borrower.  At origination of
a  mortgage  loan  involving  a land  trust,  the  borrower  executes a separate
undertaking  to make payments on the mortgage note.  The  mortgagee's  authority
under  a  mortgage,  the  trustee's  authority  under a deed  of  trust  and the
grantee's  authority  under a deed to secure  debt are  governed  by the express
provisions of the  mortgage,  the law of the state in which the real property is
located, some federal laws (including the Servicemembers' Civil Relief Act) and,
in some cases, in deed of trust transactions, the directions of the beneficiary.

        The  mortgages  that  encumber  multifamily  properties  may  contain an
assignment  of rents and leases,  pursuant to which the borrower  assigns to the
lender the borrower's right, title and interest as landlord under each lease and
the income derived therefrom, while retaining a revocable license to collect the
rents for so long as there is no default. If the borrower defaults,  the license
terminates  and the  lender is  entitled  to collect  the  rents.  Local law may
require  that  the  lender  take  possession  of the  property  and/or  obtain a
court-appointed receiver before becoming entitled to collect the rents.

INTEREST IN REAL PROPERTY

        The real property covered by a mortgage, deed of trust, security deed or
deed to  secure  debt is most  often the fee  estate  in land and  improvements.
However, that instrument may encumber other interests in real property such as a
tenant's interest in a lease of land or improvements, or both, and the leasehold
estate  created by that  lease.  An  instrument  covering  an  interest  in real
property other than the fee estate requires special provisions in the instrument
creating that interest or in the mortgage,  deed of trust, security deed or deed
to secure debt, to protect the mortgagee  against  termination  of that interest
before the  mortgage,  deed of trust,  security  deed or deed to secure  debt is
paid.  The  depositor,  the  Asset  Seller  or  other  entity  specified  in the
prospectus  supplement will make representations and warranties in the Agreement
or  representations  and  warranties  will be  assigned  to the  trustee for any
mortgage   loans   secured  by  an  interest  in  a  leasehold   estate.   Those
representation  and  warranties,  if  applicable,  will  be  set  forth  in  the
prospectus supplement.

COOPERATIVE LOANS

        If specified in the prospectus  supplement,  the mortgage loans may also
consist of cooperative apartment loans ("Cooperative Loans") secured by security
interests  in  shares   issued  by  a   cooperative   housing   corporation   (a
"Cooperative")  and in the related  proprietary  leases or occupancy  agreements
granting exclusive rights to occupy specific dwelling units in the cooperatives'
buildings.  The  security  agreement  will create a lien upon,  or grant a title
interest in, the property  that it covers,  the priority of which will depend on
the  terms  of the  particular  security  agreement  as  well  as the  order  of
recordation of the agreement in the appropriate  recording office.  That lien or
title  interest is not prior to the lien for real estate  taxes and  assessments
and other charges imposed under governmental police powers.

        Each Cooperative owns in fee or has a leasehold interest in all the real
property and owns in fee or leases the building and all separate  dwelling units
in the building. The Cooperative is directly responsible for property management
and, in most cases, payment of real estate taxes, other governmental impositions
and hazard and liability insurance.  If there is a blanket mortgage or mortgages
on the cooperative  apartment  building or underlying  land, as is generally the
case, or an underlying lease of the land, as is the case in some instances,  the
Cooperative,  as  property  borrower,  or  lessee,  as the case may be,  is also
responsible for meeting these mortgage or rental obligations. A blanket mortgage
is  ordinarily  incurred  by the  cooperative  in  connection  with  either  the
construction or purchase of the Cooperative's apartment building or obtaining of
capital by the

                                       80



Cooperative.  The interest of the occupant under proprietary leases or occupancy
agreements  as  to  which  that   Cooperative  is  the  landlord  are  generally
subordinate  to the  interest  of the  holder of a blanket  mortgage  and to the
interest of the holder of a land lease.

        If the Cooperative is unable to meet the payment obligations (1) arising
under a  blanket  mortgage,  the  mortgagee  holding a  blanket  mortgage  could
foreclose on that mortgage and terminate all subordinate  proprietary leases and
occupancy  agreements  or (2) arising  under its land  lease,  the holder of the
landlord's  interest under the land lease could terminate it and all subordinate
proprietary  leases and  occupancy  agreements.  Also,  a blanket  mortgage on a
cooperative may provide  financing in the form of a mortgage that does not fully
amortize, with a significant portion of principal being due in one final payment
at maturity.  The inability of the  Cooperative  to refinance a mortgage and its
consequent inability to make that final payment could lead to foreclosure by the
mortgagee.  Similarly,  a land lease has an expiration date and the inability of
the Cooperative to extend its term or, in the alternative,  to purchase the land
could lead to  termination  of the  Cooperative's  interest in the  property and
termination of all proprietary leases and occupancy agreement.  In either event,
a  foreclosure  by the holder of a blanket  mortgage or the  termination  of the
underlying  lease could  eliminate  or  significantly  diminish the value of any
collateral held by the lender that financed the purchase by an individual tenant
stockholder of  cooperative  shares or, in the case of the mortgage  loans,  the
collateral securing the Cooperative Loans.

        The Cooperative is owned by  tenant-stockholders  who, through ownership
of stock or shares in the corporation,  receive  proprietary  lease or occupancy
agreements that confer exclusive rights to occupy specific units.  Generally,  a
tenant-stockholder  of  a  Cooperative  must  make  a  monthly  payment  to  the
Cooperative  representing  that  tenant-stockholder's  pro  rata  share  of  the
Cooperative's   payments  for  its  blanket   mortgage,   real  property  taxes,
maintenance  expenses  and other  capital or  ordinary  expenses.  An  ownership
interest in a Cooperative and accompanying occupancy rights are financed through
a Cooperative  Loan evidenced by a promissory  note and secured by an assignment
of and a security interest in the occupancy agreement or proprietary lease and a
security interest in the related  Cooperative shares. The lender generally takes
possession of the share  certificate and a counterpart of the proprietary  lease
or occupancy  agreement and a financing statement covering the proprietary lease
or occupancy  agreement and the  cooperative  shares is filed in the appropriate
state and local  offices to perfect the  lender's  interest  in its  collateral.
Subject   to   the   limitations   discussed   below,   upon   default   of  the
tenant-stockholder,  the lender may sue for  judgment  on the  promissory  note,
dispose of the  collateral  at a public or  private  sale or  otherwise  proceed
against the collateral or tenant-stockholder as an individual as provided in the
security agreement covering the assignment of the proprietary lease or occupancy
agreement and the pledge of Cooperative shares. See  "--Foreclosure--Cooperative
Loans" below.

LAND SALE CONTRACTS

        Under an  installment  land sale contract for the sale of real estate (a
"land sale  contract")  the  contract  seller  (hereinafter  referred  to as the
"contract  lender")  retains  legal  title to the  property  and enters  into an
agreement with the contract purchaser  (hereinafter referred to as the "contract
borrower") for the payment of the purchase price,  plus interest,  over the term
of the land sale  contract.  Only after full  performance by the borrower of the
contract is the contract lender  obligated to convey title to the real estate to
the purchaser. As with mortgage or deed of trust financing, during the effective
period of the land sale  contract,  the  contract  borrower is  responsible  for
maintaining  the property in good  condition  and for paying real estate  taxes,
assessments and hazard insurance premiums associated with the property.

        The method of  enforcing  the  rights of the  contract  lender  under an
installment contract varies on a state-by-state basis depending on the extent to
which state courts are willing,  or able

                                       81



pursuant to state  statute,  to enforce the contract  strictly  according to its
terms. The terms of land sale contracts  generally  provide that upon default by
the  contract  borrower,  the  borrower  loses his or her  right to  occupy  the
property,  the entire  indebtedness  is accelerated,  and the buyer's  equitable
interest in the property is  forfeited.  The contract  lender in that  situation
does not have to  foreclose to obtain  title to the  property,  although in some
cases a quiet title  action is in order if the  contract  borrower has filed the
land  sale  contract  in local  land  records  and an  ejectment  action  may be
necessary to recover possession.

        In a few  states,  particularly  in cases of contract  borrower  default
during the early years of a land sale contract, the courts will permit ejectment
of the buyer and a forfeiture of his or her interest in the  property.  However,
most state  legislatures  have  enacted  provisions  by analogy to mortgage  law
protecting  borrowers  under land sale contracts from the harsh  consequences of
forfeiture. Under those statues, a judicial contract may be reinstated upon full
payment of the  default  amount  and the  borrower  may have a  post-foreclosure
statutory  redemption  right.  In other  states,  courts in equity  may permit a
contract borrower with significant  investment in the property under a land sale
contract  for the sale of real  estate  to  share  the  proceeds  of sale of the
property after the indebtedness is repaid or may otherwise refuse to enforce the
forfeiture  clause.  Nevertheless,  generally  speaking,  the contract  lender's
procedures  for obtaining  possession and clear title under a land sale contract
for the sale of real  estate in a  particular  state are  simpler  and less time
consuming and costly than are the procedures for foreclosing and obtaining clear
title to a mortgaged property.

FORECLOSURE

        GENERAL

        Foreclosure  is a legal  procedure  that allows the mortgagee to recover
its mortgage debt by enforcing its rights and available legal remedies under the
mortgage. If the mortgagor defaults in payment or performance of its obligations
under the note or mortgage, the mortgagee has the right to institute foreclosure
proceedings  to sell the  mortgaged  property  at public  auction to satisfy the
indebtedness.

        Foreclosure procedures for the enforcement of a mortgage vary from state
to state. Two primary methods of foreclosing a mortgage are judicial foreclosure
and non-judicial foreclosure pursuant to a power of sale granted in the mortgage
instrument.  There are several other  foreclosure  procedures  available in some
states  that are either  infrequently  used or  available  only in some  limited
circumstances, such as strict foreclosure.

        JUDICIAL FORECLOSURE

        A  judicial  foreclosure  proceeding  is  conducted  in a  court  having
jurisdiction over the mortgaged property.  Generally, the action is initiated by
the service of legal  pleadings upon all parties having an interest of record in
the real  property.  Delays in completion of the  foreclosure  may  occasionally
result from  difficulties  in locating  defendants.  When the lender's  right to
foreclose  is  contested,  the legal  proceedings  can be  time-consuming.  Upon
successful completion of a judicial foreclosure proceeding,  the court generally
issues a judgment  of  foreclosure  and  appoints a referee or other  officer to
conduct a public sale of the mortgaged property,  the proceeds of which are used
to satisfy the judgment. Those sales are made in accordance with procedures that
vary from state to state.

        EQUITABLE LIMITATIONS ON ENFORCEABILITY OF CERTAIN PROVISIONS

        United  States  courts  have  traditionally  imposed  general  equitable
principles  to limit the remedies  available to a mortgagee in  connection  with
foreclosure. These equitable principles are

                                       82



generally  designed to relieve the  borrower  from the legal  effect of mortgage
defaults, to the extent that the effect is perceived as harsh or unfair. Relying
on those  principles,  a court  may alter  the  specific  terms of a loan to the
extent  it  considers  necessary  to  prevent  or  remedy  an  injustice,  undue
oppression or overreaching,  or may require the lender to undertake  affirmative
and expensive  actions to determine the cause of the borrower's  default and the
likelihood that the borrower will be able to reinstate the loan.

        In some cases,  courts have substituted  their judgment for the lender's
and have required that lenders  reinstate  loans or recast payment  schedules to
accommodate  borrowers who are suffering from a temporary financial  disability.
In other cases,  courts have limited the right of the lender to foreclose if the
default  under the  mortgage  is not  monetary,  e.g.,  the  borrower  failed to
maintain the mortgaged  property  adequately  or the borrower  executed a junior
mortgage  on the  mortgaged  property.  The  exercise by the court of its equity
powers will depend on the individual circumstances of each case presented to it.
Finally,  some courts have been faced with the issue of whether federal or state
constitutional  provisions  reflecting due process  concerns for adequate notice
require  that a borrower  receive  notice in addition to  statutorily-prescribed
minimum notice. For the most part, these cases have upheld the reasonableness of
the  notice  provisions  or have  found  that a  public  sale  under a  mortgage
providing for a power of sale does not involve sufficient state action to afford
constitutional protections to the borrower.

        NON-JUDICIAL FORECLOSURE/POWER OF SALE

        Foreclosure  of  a  deed  of  trust  is  generally   accomplished  by  a
non-judicial trustee's sale pursuant to the power of sale granted in the deed of
trust. A power of sale is typically  granted in a deed of trust.  It may also be
contained  in any other type of  mortgage  instrument.  A power of sale allows a
non-judicial  public sale to be conducted generally following a request from the
beneficiary/lender  to the trustee to sell the property  upon any default by the
borrower  under the terms of the mortgage  note or the mortgage  instrument  and
after  notice  of sale is given in  accordance  with the  terms of the  mortgage
instrument, as well as applicable state law.

        In some states,  before the sale, the trustee under a deed of trust must
record a notice of default  and  notice of sale and send a copy to the  borrower
and to any other  party  who has  recorded  a request  for a copy of a notice of
default and notice of sale. In addition, in some states the trustee must provide
notice to any other party  having an  interest  of record in the real  property,
including junior lienholders.  A notice of sale must be posted in a public place
and, in most  states,  published  for a specified  period of time in one or more
newspapers.  The borrower or junior lienholder may then have the right, during a
reinstatement  period required in some states, to cure the default by paying the
entire  actual  amount  in  arrears  (without  acceleration)  plus the  expenses
incurred in  enforcing  the  obligation.  In other  states,  the borrower or the
junior  lienholder is not provided a period to reinstate the loan,  but has only
the right to pay off the entire debt to prevent the foreclosure sale. Generally,
the procedure  for public sale,  the parties  entitled to notice,  the method of
giving notice and the applicable time periods are governed by state law and vary
among  the  states.  Foreclosure  of a deed to  secure  debt  is also  generally
accomplished by a non-judicial sale similar to that required by a deed of trust,
except  that the  lender or its  agent,  rather  than a  trustee,  is  typically
empowered to perform the sale in accordance with the terms of the deed to secure
debt and applicable law.

        PUBLIC SALE

        A third party may be  unwilling  to  purchase a mortgaged  property at a
public sale because of the difficulty in determining  the value of that property
at the time of sale,  due to,  among other  things,  redemption  rights that may
exist and the possibility of physical  deterioration  of the property during the
foreclosure  proceedings.  For these  reasons,  it is common  for the  lender to
purchase  the  mortgaged  property  for an  amount  equal  to or less  than  the
underlying debt and

                                       83



accrued and unpaid interest plus the expenses of foreclosure.  Generally,  state
law controls the amount of foreclosure  costs and expenses that may be recovered
by a lender.  Thereafter,  subject  to the  borrower's  right in some  states to
remain in possession during a redemption period, if applicable,  the lender will
become  the owner of the  property  and have both the  benefits  and  burdens of
ownership  of the  mortgaged  property.  For  example,  the lender  will  become
obligated to pay taxes,  obtain casualty  insurance and to make those repairs at
its own expense as are necessary to render the property  suitable for sale.  The
lender will  commonly  obtain the  services of a real estate  broker and pay the
broker's  commission in connection  with the sale of the property.  Depending on
market  conditions,  the  ultimate  proceeds of the sale of the property may not
equal the lender's  investment  in the  property.  Moreover,  a lender  commonly
incurs  substantial legal fees and court costs in acquiring a mortgaged property
through contested foreclosure and/or bankruptcy  proceedings.  Generally,  state
law controls the amount of foreclosure expenses and costs,  including attorneys'
fees, that may be recovered by a lender.

        A junior mortgagee may not foreclose on the property securing the junior
mortgage  unless it forecloses  subject to senior  mortgages and any other prior
liens, in which case it may be obliged to make payments on the senior  mortgages
to avoid their foreclosure. In addition, if the foreclosure of a junior mortgage
triggers  the  enforcement  of a  "due-on-sale"  clause  contained  in a  senior
mortgage,  the junior  mortgagee  may be  required to pay the full amount of the
senior mortgage to avoid its foreclosure. Accordingly, for those mortgage loans,
if any, that are junior mortgage loans, if the lender purchases the property the
lender's title will be subject to all senior mortgages, prior liens and specific
governmental liens.

        The  proceeds  received  by the  referee  or  trustee  from the sale are
applied first to the costs,  fees and expenses of sale and then in  satisfaction
of the indebtedness  secured by the mortgage under which the sale was conducted.
Any proceeds  remaining after satisfaction of senior mortgage debt are generally
payable to the holders of junior  mortgages  and other liens and claims in order
of their  priority,  whether or not the borrower is in default.  Any  additional
proceeds are generally  payable to the borrower.  The payment of the proceeds to
the  holders  of junior  mortgages  may occur in the  foreclosure  action of the
senior  mortgage  or a  subsequent  ancillary  proceeding  or  may  require  the
institution of separate legal proceedings by those holders.

        RIGHTS OF REDEMPTION

        The  purposes of a  foreclosure  action are to enable the  mortgagee  to
realize upon its security and to bar the  borrower,  and all persons who have an
interest in the property that is subordinate  to the mortgage being  foreclosed,
from  exercise  of their  "equity  of  redemption."  The  doctrine  of equity of
redemption provides that, until the property covered by a mortgage has been sold
in accordance with a properly conducted  foreclosure and foreclosure sale, those
having an interest that is subordinate to that of the foreclosing mortgagee have
an equity of  redemption  and may redeem the  property by paying the entire debt
with interest. In addition, in some states, when a foreclosure action has begun,
the redeeming  party must pay some of the costs of that action.  Those having an
equity  of  redemption  must  generally  be  made  parties  and  joined  in  the
foreclosure proceeding in order for their equity of redemption to be cut off and
terminated.

        The equity of  redemption  is a  common-law  (non-statutory)  right that
exists before  completion of the  foreclosure,  is not waivable by the borrower,
must be exercised before  foreclosure sale and should be distinguished  from the
post-sale statutory rights of redemption. In some states, after sale pursuant to
a deed of trust or foreclosure of a mortgage, the borrower and foreclosed junior
lienors are given a statutory  period in which to redeem the  property  from the
foreclosure  sale.  In some  states,  statutory  redemption  may occur only upon
payment of the  foreclosure  sale  price.  In other  states,  redemption  may be
authorized  if the  former  borrower  pays only a portion  of the sums due.  The
effect of a statutory  right of  redemption  is to  diminish  the ability of the
lender to sell the  foreclosed  property.  The exercise of a right of redemption
would

                                       84



defeat the title of any purchaser  from a foreclosure  sale or sale under a deed
of trust. Consequently, the practical effect of the redemption right is to force
the lender to maintain the property and pay the expenses of ownership  until the
redemption  period has expired.  In some states, a post-sale  statutory right of
redemption  may exist  following  a judicial  foreclosure,  but not  following a
trustee's sale under a deed of trust.

        Under the REMIC  Provisions  currently in effect,  property  acquired by
foreclosure  generally must not be held for more than three years from the close
of the calendar year of its acquisition.  For a series of Notes or Certificates,
as applicable,  for which an election is made to qualify the issuing entity or a
part of the issuing  entity as a REMIC,  the  Agreement  will permit  foreclosed
property to be held for more than such three year period if the Internal Revenue
Service  grants  an  extension  of time  within  which to sell the  property  or
independent  counsel  renders an opinion to the effect that holding the property
for that additional period is permissible under the REMIC Provisions.

        COOPERATIVE LOANS

        The Cooperative  shares owned by the  tenant-stockholder  and pledged to
the lender are, in almost all cases,  subject to restrictions on transfer as set
forth in the  Cooperative's  certificate of incorporation and bylaws, as well as
the  proprietary  lease  or  occupancy  agreement,  and may be  canceled  by the
Cooperative  for  failure  by  the  tenant-stockholder  to  pay  rent  or  other
obligations  or charges owed by that  tenant-stockholder,  including  mechanics'
liens   against   the   cooperative   apartment   building   incurred   by  that
tenant-stockholder.  The  proprietary  lease or  occupancy  agreement  generally
permit  the  Cooperative  to  terminate  the lease or  agreement  in the event a
borrower  fails to make  payments or defaults in the  performance  of  covenants
required under the  proprietary  lease or occupancy  agreement.  Typically,  the
lender and the Cooperative  enter into a recognition  agreement that establishes
the  rights  and  obligations  of both  parties in the event of a default by the
tenant-stockholder  under the  proprietary  lease or  occupancy  agreement  will
usually constitute a default under the security agreement between the lender and
the tenant-stockholder.

        The   recognition    agreement   generally   provides   that,   if   the
tenant-stockholder  has  defaulted  under  the  proprietary  lease or  occupancy
agreement,  the  Cooperative  will  take no action to  terminate  that  lease or
agreement  until the lender has been  provided with an  opportunity  to cure the
default.  The recognition  agreement  typically provides that if the proprietary
lease or occupancy  agreement is terminated,  the Cooperative will recognize the
lender's  lien  against  proceeds  from the sale of the  Cooperative  apartment,
subject,  however, to the Cooperative's right to sums due under that proprietary
lease or occupancy  agreement.  The total amount owed to the  Cooperative by the
tenant-stockholder,  which the lender  generally  cannot  restrict  and does not
monitor,  could  reduce  the  value  of the  collateral  below  the  outstanding
principal balance of the Cooperative Loan and accrued and unpaid interest on the
Cooperative Loan.

        Recognition  agreements  also provide that in the event of a foreclosure
on a  Cooperative  Loan,  the lender must obtain the  approval or consent of the
Cooperative  as  required  by the  proprietary  lease  before  transferring  the
Cooperative shares or assigning the proprietary lease. Generally,  the lender is
not limited in any rights it may have to dispossess the tenant-stockholders.

        In some states, foreclosure on the Cooperative shares is accomplished by
a sale  in  accordance  with  the  provisions  of  Article  9 of the UCC and the
security agreement relating to those shares.  Article 9 of the UCC requires that
a sale be conducted in a "commercially reasonable" manner. Whether a foreclosure
sale has been conducted in a "commercially reasonable" manner will depend on the
facts in each case. In determining commercial reasonableness,  a court will look
to the notice given the debtor and the method,  manner, time, place and terms of
the foreclosure.  Generally, a sale conducted according to the usual practice of
banks selling similar collateral will be considered reasonably conducted.

                                       85



        Article  9 of the UCC  provides  that the  proceeds  of the sale will be
applied  first to pay the costs and expenses of the sale and then to satisfy the
indebtedness  secured  by  the  lender's  security  interest.   The  recognition
agreement,  however, generally provides that the lender's right to reimbursement
is  subject  to the  right of the  Cooperatives  to  receive  sums due under the
proprietary lease or occupancy agreement.  If there are proceeds remaining,  the
lender must account to the tenant-stockholder for the surplus.  Conversely, if a
portion of the indebtedness remains unpaid, the  tenant-stockholder is generally
responsible for the deficiency.

        In the case of  foreclosure  on a  building  that was  converted  from a
rental building to a building owned by a Cooperative under a non-eviction  plan,
some states  require  that a purchaser at a  foreclosure  sale take the property
subject to rent  control and rent  stabilization  laws that apply to tenants who
elected to remain in a building so converted.

JUNIOR MORTGAGES

        Some of the mortgage  loans may be secured by junior  mortgages or deeds
of trust,  that are  subordinate to first or other senior  mortgages or deeds of
trust held by other lenders. The rights of the issuing entity as the holder of a
junior deed of trust or a junior mortgage are subordinate in lien and in payment
to those of the holder of the senior  mortgage or deed of trust,  including  the
prior rights of the senior  mortgagee or beneficiary to receive and apply hazard
insurance and condemnation  proceeds and, upon default of the borrower, to cause
a foreclosure on the property. Upon completion of the foreclosure proceedings by
the holder of the senior mortgage or the sale pursuant to the deed of trust, the
junior mortgagee's or junior  beneficiary's lien will be extinguished unless the
junior lienholder satisfies the defaulted senior loan or asserts its subordinate
interest in a property in foreclosure proceedings. See "--Foreclosure" above.

        Furthermore,  because the terms of the junior  mortgage or deed of trust
are  subordinate  to the terms of the first  mortgage  or deed of trust,  in the
event of a conflict between the terms of the first mortgage or deed of trust and
the junior mortgage or deed of trust, the terms of the first mortgage or deed of
trust  will  generally  govern.  Upon a failure  of the  borrower  or trustor to
perform any of its obligations, the senior mortgagee or beneficiary,  subject to
the terms of the senior mortgage or deed of trust, may have the right to perform
the  obligation  itself.  Generally,  all sums so expended by the  mortgagee  or
beneficiary  become part of the indebtedness  secured by the mortgage or deed of
trust.  To the extent a first  mortgagee  expends  these  sums,  these sums will
generally have priority over all sums due under the junior mortgage.

ANTI-DEFICIENCY LEGISLATION AND OTHER LIMITATIONS ON LENDERS

        Statutes in some states limit the right of a beneficiary under a deed of
trust or a mortgagee  under a mortgage to obtain a deficiency  judgment  against
the borrower  following  foreclosure or sale under a deed of trust. A deficiency
judgment would be a personal  judgment  against the former borrower equal to the
difference  between  the net amount  realized  upon the public  sale of the real
property and the amount due to the lender.

        Some states require the lender to exhaust the security  afforded under a
mortgage by foreclosure in an attempt to satisfy the full debt before bringing a
personal action against the borrower.  In some other states,  the lender has the
option of bringing a personal  action  against the  borrower on the debt without
first exhausting that security;  however,  in some of these states,  the lender,
following  judgment  on the  personal  action,  may be deemed to have  elected a
remedy  and may be  precluded  from  exercising  remedies  with  respect  to the
security.  In some  cases,  a  lender  will be  precluded  from  exercising  any
additional  rights  under  the  note  or  mortgage  if it has  taken  any  prior
enforcement  action.   Consequently,   the  practical  effect  of  the  election
requirement,  in those states  permitting  that  election,  is that lenders will
usually  proceed  against the  security  first  rather than  bringing a personal
action against the borrower. Finally, other statutory provisions

                                       86



limit any deficiency  judgment against the former borrower  following a judicial
sale to the excess of the  outstanding  debt over the fair  market  value of the
property  at the time of the  public  sale.  The  purpose of these  statutes  is
generally to prevent a lender from obtaining a large deficiency judgment against
the former borrower as a result of low or no bids at the judicial sale.

        In addition to anti-deficiency and related  legislation,  numerous other
federal and state statutory  provisions,  including the federal  bankruptcy laws
and state laws  affording  relief to debtors,  may interfere  with or affect the
ability of a secured mortgage lender to realize upon its security.  For example,
numerous statutory provisions under the United States Bankruptcy Code, 11 U.S.C.
Sections 101 et seq. (the "Bankruptcy  Code"),  may interfere with or affect the
ability of the secured  mortgage lender to obtain payment of a mortgage loan, to
realize upon  collateral  and/or  enforce a deficiency  judgment.  Under federal
bankruptcy  law,  virtually  all  actions  (including  foreclosure  actions  and
deficiency judgment  proceedings) are automatically  stayed upon the filing of a
bankruptcy petition, and often no interest or principal payments are made during
the course of the bankruptcy  proceeding.  In a case under the Bankruptcy  Code,
the secured party is precluded from foreclosing  without  authorization from the
bankruptcy court. In addition, a court with federal bankruptcy  jurisdiction may
permit a debtor  through  his or her  Chapter  11 or  Chapter  13 plan to cure a
monetary  default in respect of a mortgage  loan by paying  arrearages  within a
reasonable  time period and  reinstating  the  original  mortgage  loan  payment
schedule even though the lender accelerated the mortgage loan and final judgment
of foreclosure had been entered in state court (provided no foreclosure sale had
yet  occurred)  before the filing of the  debtor's  petition.  Some  courts with
federal  bankruptcy  jurisdiction  have approved plans,  based on the particular
facts of the case, that affected the curing of a mortgage loan default by paying
arrearages over a number of years.

        If a mortgage loan is secured by property not  consisting  solely of the
debtor's  principal  residence,  the Bankruptcy  Code also permits that mortgage
loan to be modified. These modifications may include reducing the amount of each
monthly payment, changing the rate of interest, altering the repayment schedule,
and reducing the lender's security  interest to the value of the property,  thus
leaving  the lender in the  position  of a general  unsecured  creditor  for the
difference between the value of the property and the outstanding  balance of the
mortgage loan. Some courts have permitted these  modifications when the mortgage
loan is  secured  both  by the  debtor's  principal  residence  and by  personal
property.

        Some tax liens arising under the Code may in some circumstances  provide
priority over the lien of a mortgage or deed of trust. In addition,  substantive
requirements   are  imposed  upon  mortgage   lenders  in  connection  with  the
origination  and the  servicing of mortgage  loans by numerous  federal and some
state consumer protection laws. These laws include the federal  Truth-in-Lending
Act, Real Estate Settlement  Procedures Act, Equal Credit  Opportunity Act, Fair
Credit  Billing  Act,  Fair Credit  Reporting  Act and related  statutes.  These
federal laws impose specific  statutory  liabilities  upon lenders who originate
mortgage  loans and who fail to comply with the  provisions  of the law. In some
cases this liability may affect assignees of the mortgage loans.

        Generally,  Article  9 of the UCC  governs  foreclosure  on  Cooperative
shares and the related  proprietary  lease or occupancy  agreement.  Some courts
have interpreted  Section 9-504 of the UCC to prohibit a deficiency award unless
the creditor  establishes that the sale of the collateral (which, in the case of
a  Cooperative  Loan,  would be the shares of the  Cooperative  and the  related
proprietary  lease or  occupancy  agreement)  was  conducted  in a  commercially
reasonable manner.

        FEDERAL   BANKRUPTCY   LAWS  RELATING  TO  MORTGAGE   LOANS  SECURED  BY
        MULTIFAMILY PROPERTY

        Section 365(a) of the Bankruptcy Code generally  provides that a trustee
or a  debtor-in-possession  in a  bankruptcy  or  reorganization  case under the
Bankruptcy Code has the power to assume or to reject an executory contract or an
unexpired lease of the debtor, in each case subject

                                       87



to the approval of the bankruptcy court  administering  the case. If the trustee
or debtor-in-  possession  rejects an executory  contract or an unexpired lease,
rejection generally  constitutes a breach of the executory contract or unexpired
lease  immediately  before  the  date  of  the  filing  of  the  petition.  As a
consequence,  if the  mortgagor  is the other party or parties to the  executory
contract or unexpired lease, such as a lessor under a lease, the mortgagor would
have only an unsecured  claim against the debtor for damages  resulting from the
breach, which could adversely affect the security for the related mortgage loan.
Moreover,  under Section 502(b)(6) of the Bankruptcy Code, the claim of a lessor
for damages from the  termination of a lease of real property will be limited to
the sum of (1) the rent  reserved by the lease,  without  acceleration,  for the
greater of one year or 15 percent,  not to exceed three years,  of the remaining
term of the  lease,  following  the  earlier  of the date of the  filing  of the
petition  and  the  date  on  which  the  lender  repossessed,   or  the  lessee
surrendered,  the leased property,  and (2) any unpaid rent due under the lease,
without acceleration, on the earlier of these dates.

        Under Section 365(h) of the Bankruptcy  Code, if a trustee for a lessor,
or a  lessor  as a  debtor-in-possession,  rejects  an  unexpired  lease of real
property,  the lessee may treat the lease as  terminated by rejection or, in the
alternative,  may remain in  possession  of the leasehold for the balance of the
term and for any renewal or  extension  of the term that is  enforceable  by the
lessee under applicable  nonbankruptcy law. The Bankruptcy Code provides that if
a lessee elects to remain in possession  after rejection of a lease,  the lessee
may offset  against rents  reserved  under the lease for the balance of the term
after the date of rejection of the lease, and any renewal or extension  thereof,
any  damages  occurring  after  that date  caused by the  nonperformance  of any
obligation of the lessor under the lease after that date.

        Under Section  365(f) of the  Bankruptcy  Code, if a trustee  assumes an
executory  contract  or an  unexpired  lease  of  the  debtor,  the  trustee  or
debtor-in-possession  generally may assign the  executory  contract or unexpired
lease,   notwithstanding  any  provision  therein  or  in  applicable  law  that
prohibits, restricts or conditions the assignment,  provided that the trustee or
debtor-in-possession  provides adequate  assurance of future  performance by the
assignee.  In addition,  no party to an executory contract or an unexpired lease
may terminate or modify any rights or obligations under an executory contract or
an  unexpired  lease at any time  after  the  commencement  of a case  under the
Bankruptcy  Code solely  because of a  provision  in the  executory  contract or
unexpired  lease or in applicable  law  conditioned  upon the  assignment of the
executory  contract or unexpired  lease.  Thus, an undetermined  third party may
assume the  obligations of the lessee or a mortgagor  under a lease in the event
of  commencement  of a proceeding  under the Bankruptcy Code with respect to the
lessee or a mortgagor, as applicable.

        Under Sections  363(b) and (f) of the  Bankruptcy  Code, a trustee for a
lessor, or a lessor as debtor-in-possession,  may, despite the provisions of the
related  mortgage  loan to the contrary,  sell the  Mortgaged  Property free and
clear of all liens, which liens would then attach to the proceeds of the sale.

ENVIRONMENTAL CONSIDERATIONS

        A lender may be subject to unforeseen  environmental risks when taking a
security interest in real or personal  property.  Property subject to a security
interest  may be  subject to  federal,  state,  and local  laws and  regulations
relating  to  environmental  protection.  These laws may  regulate,  among other
things:  emissions of air  pollutants;  discharges of wastewater or storm water;
generation,  transport,  storage or disposal  of  hazardous  waste or  hazardous
substances; operation, closure and removal of underground storage tanks; removal
and disposal of asbestos-containing  materials;  and/or management of electrical
or other equipment  containing  polychlorinated  biphenyls ("PCBs").  Failure to
comply  with these laws and  regulations  may result in  significant  penalties,
including civil and criminal fines. Under the laws of some states, environmental
contamination  on a property  may give rise to a lien on the  property to ensure
the availability

                                       88



and/or  reimbursement  of cleanup costs.  Generally all subsequent liens on that
property  are  subordinated  to the  environmentally-related  lien and,  in some
states,   even  prior   recorded   liens  are   subordinated   to  these   liens
("Superliens").  In the latter states, the security interest of the trustee in a
property that is subject to a Superlien could be adversely affected.

        Under the federal Comprehensive Environmental Response, Compensation and
Liability  Act, as amended  ("CERCLA"),  and under state law in some  states,  a
secured  party that takes a deed in lieu of  foreclosure,  purchases a mortgaged
property at a  foreclosure  sale,  operates a mortgaged  property or  undertakes
particular  types of activities that may constitute  management of the mortgaged
property  may  become  liable in some  circumstances  for the  cleanup  costs of
remedial action if hazardous  wastes or hazardous  substances have been released
or disposed of on the property.  These cleanup costs may be substantial.  CERCLA
imposes  strict,  as well as joint  and  several,  liability  for  environmental
remediation  and/or damage costs on several classes of "potentially  responsible
parties," including current "owners and/or operators" of property,  irrespective
of whether those owners or operators caused or contributed to the  contamination
on the property.  In addition,  owners and operators of properties that generate
hazardous  substances that are disposed of at other "off-site"  locations may be
held strictly, jointly and severally liable for environmental remediation and/or
damages at those off-site locations. Many states also have laws that are similar
to CERCLA.  Liability  under CERCLA or under  similar state law could exceed the
value of the property itself as well as the total assets of the property owner.

        Although some  provisions of the Asset  Conservation  Act (as defined in
this prospectus) apply to trusts and fiduciaries, the law is somewhat unclear as
to whether and under what precise circumstances cleanup costs, or the obligation
to take  remedial  actions,  could be imposed on a secured  lender,  such as the
issuing entity.  Under the laws of some states and under CERCLA, a lender may be
liable as an "owner or operator" for costs of addressing  releases or threatened
releases of hazardous  substances on a mortgaged  property if that lender or its
agents or employees have  "participated  in the management" of the operations of
the  borrower,  even though the  environmental  damage or threat was caused by a
prior owner or current  owner or operator or other third  party.  Excluded  from
CERCLA's   definition   of  "owner  or   operator"  is  a  person  "who  without
participating  in the  management  of . . . [the]  facility,  holds  indicia  of
ownership  primarily to protect his security  interest"  (the  "secured-creditor
exemption"). This exemption for holders of a security interest such as a secured
lender  applies  only to the extent that a lender  seeks to protect its security
interest  in  the  contaminated  facility  or  property.  Thus,  if  a  lender's
activities  begin to  encroach  on the actual  management  of that  facility  or
property,  the lender faces potential  liability as an "owner or operator" under
CERCLA.  Similarly,  when a lender  forecloses and takes title to a contaminated
facility or property, the lender may incur potential CERCLA liability in various
circumstances, including among others, when it holds the facility or property as
an  investment  (including  leasing the facility or property to a third  party),
fails to market the  property in a timely  fashion or fails to properly  address
environmental conditions at the property or facility.

        The  Resource  Conservation  and  Recovery  Act,  as  amended  ("RCRA"),
contains  a similar  secured-creditor  exemption  for those  lenders  who hold a
security  interest in a petroleum  underground  storage  tank ("UST") or in real
estate containing a UST, or that acquire title to a petroleum UST or facility or
property  on which a UST is  located.  As under  CERCLA,  a lender  may lose its
secured-creditor  exemption  and be held  liable  under  RCRA as a UST  owner or
operator if that lender or its employees or agents participate in the management
of the UST. In addition,  if the lender takes title to or  possession of the UST
or  the  real  estate   containing  the  UST,  under  some   circumstances   the
secured-creditor exemption may be deemed to be unavailable.

        A decision  in May 1990 of the United  States  Court of Appeals  for the
Eleventh Circuit in United States v. Fleet Factors Corp. very narrowly construed
CERCLA's secured-creditor exemption. The court's opinion suggested that a lender
need not have involved  itself in the  day-to-day  operations of the facility or
participated in decisions relating to hazardous waste to be liable

                                       89



under CERCLA; rather, liability could attach to a lender if its involvement with
the  management of the facility were broad enough to support the inference  that
the lender had the capacity to influence the  borrower's  treatment of hazardous
waste.  The court added that a lender's  capacity to influence  these  decisions
could be inferred from the extent of its involvement in the facility's financial
management.  A subsequent decision by the United States Court of Appeals for the
Ninth Circuit in re Bergsoe Metal Corp.,  apparently  disagreeing  with, but not
expressly contradicting, the Fleet Factors court, held that a secured lender had
no liability absent "some actual  management of the facility" on the part of the
lender.

        Court   decisions   have  taken  varying  views  of  the  scope  of  the
secured-creditor exemption, leading to administrative and legislative efforts to
provide guidance to lenders on the scope of activities that would trigger CERCLA
and/or RCRA  liability.  Until  recently,  these  efforts have failed to provide
substantial guidance.

        On September 28, 1996, however,  Congress enacted,  and on September 30,
1996, the President signed into law the Asset Conservation  Lender Liability and
Deposit  Insurance  Protection Act of 1996 (the "Asset  Conservation  Act"). The
Asset Conservation Act was intended to clarify the scope of the secured creditor
exemption under both CERCLA and RCRA. The Asset Conservation Act more explicitly
defined the kinds of  "participation in management" that would trigger liability
under CERCLA and specified  activities that would not constitute  "participation
in  management"  or  otherwise  result in a forfeiture  of the  secured-creditor
exemption before  foreclosure or during a workout period. The Asset Conservation
Act also clarified the extent of protection  against  liability  under CERCLA in
the event of foreclosure and authorized  specific  regulatory  clarifications of
the scope of the secured-creditor exemption for purposes of RCRA, similar to the
statutory protections under CERCLA.  However,  since the courts have not yet had
the  opportunity  to interpret  the new statutory  provisions,  the scope of the
additional  protections  offered  by the  Asset  Conservation  Act is not  fully
defined.  It also is important to note that the Asset  Conservation Act does not
offer complete protection to lenders and that the risk of liability remains.

        If a secured lender does become  liable,  it may be entitled to bring an
action  for  contribution   against  the  owner  or  operator  who  created  the
environmental  contamination or against some other liable party, but that person
or entity may be bankrupt or otherwise judgment-proof.  It is therefore possible
that cleanup or other environmental  liability costs could become a liability of
the  issuing   entity  and  occasion  a  loss  to  the  issuing  entity  and  to
securityholders in some  circumstances.  The new secured creditor  amendments to
CERCLA,  also,  would not  necessarily  affect the  potential  for  liability in
actions by either a state or a private  party under other  federal or state laws
that may impose  liability on "owners or operators" but do not  incorporate  the
secured-creditor exemption.

        Traditionally,  residential  mortgage  lenders  have not taken  steps to
evaluate  whether  hazardous  wastes or  hazardous  substances  are present with
respect to any mortgaged property before the origination of the mortgage loan or
before  foreclosure  or accepting a  deed-in-lieu  of  foreclosure.  Neither the
depositor nor any servicer  makes any  representations  or warranties or assumes
any  liability  with  respect  to:  environmental  conditions  of the  Mortgaged
Property;  the  absence,  presence or effect of  hazardous  wastes or  hazardous
substances  on, near or emanating  from the  Mortgaged  Property;  the impact on
securityholders  of any environmental  condition or presence of any substance on
or near the Mortgaged Property; or the compliance of any Mortgaged Property with
any  environmental  laws.  In  addition,  no agent,  person or entity  otherwise
affiliated with the depositor is authorized or able to make any  representation,
warranty or assumption of liability relative to any Mortgaged Property.

DUE-ON-SALE CLAUSES

        The  mortgage  loans may  contain  due-on-sale  clauses.  These  clauses
generally provide that the lender may accelerate the maturity of the loan if the
borrower  sells,  transfers  or conveys  the  related  Mortgaged  Property.  The
enforceability  of  due-on-sale  clauses has been the subject of  legislation or
litigation  in many  states  and, in some  cases,  the  enforceability  of these
clauses  was limited or denied.  However,  for some loans the  Garn-St.  Germain
Depository Institutions Act of 1982 (the "Garn-St.  Germain Act") preempts state
constitutional,  statutory  and case  law  that  prohibits  the  enforcement  of
due-on-sale  clauses and permits  lenders to enforce these clauses in accordance
with their terms,  subject to limited exceptions.  Due-on-sale clauses contained
in mortgage loans originated by federal savings and loan associations of federal
savings banks are fully enforceable pursuant to regulations of the United States
Federal Home Loan Bank Board, as succeeded by the Office of Thrift  Supervision,
which  preempt  state law  restrictions  on the  enforcement  of those  clauses.
Similarly,  "due-on-sale"  clauses in mortgage  loans made by national banks and
federal  credit  unions  are  now  fully  enforceable   pursuant  to  preemptive
regulations  of the  Comptroller  of the Currency and the National  Credit Union
Administration, respectively.

        The  Garn-St.  Germain Act also sets forth nine  specific  instances  in
which a mortgage  lender covered by the act (including  federal savings and loan
associations and federal savings banks) may not exercise a "due-on-sale" clause,
notwithstanding  the fact that a transfer  of the  property  may have  occurred.
These include intra-family transfers, some transfers by operation of law, leases
of fewer than three years and the creation of a junior encumbrance.  Regulations
promulgated  under the Garn-St.  Germain Act also  prohibit the  imposition of a
prepayment  penalty upon the  acceleration  of a loan  pursuant to a due-on-sale
clause. The inability to enforce a "due-on-sale" clause may result in a mortgage
that bears an interest rate below the current market rate being assumed by a new
home buyer rather than being paid off,  which may affect the average life of the
mortgage loans and the number of mortgage loans which may extend to maturity.

PREPAYMENT CHARGES AND LATE FEES; DEBT-ACCELERATION CLAUSES

        Some state laws restrict the  imposition of prepayment  charges and late
fees even when the loans expressly  provide for the collection of those charges.
Although the Alternative  Mortgage  Transaction  Parity Act of 1982 (the "Parity
Act"),  permits the collection of prepayment charges and late fees in connection
with  some  types  of  eligible   loans   preempting   any  contrary  state  law
prohibitions,  some states may not  recognize  the  preemptive  authority of the
Parity Act or have  formally  opted out of the Parity  Act.  As a result,  it is
possible  that  prepayment  charges and late fees may not be  collected  even on
loans that provide for the payment of those charges unless  otherwise  specified
in the  accompanying  prospectus  supplement.  The  related  servicer or another
entity identified in the accompanying  prospectus supplement will be entitled to
all prepayment  charges and late payment charges received on the loans and those
amounts will not be  available  for payment on the  certificates.  The Office of
Thrift  Supervision  ("OTS"),  the agency  that  administers  the Parity Act for
unregulated housing creditors, withdrew its favorable Parity Act regulations and
Chief Counsel Opinions that previously  authorized  lenders to charge prepayment
charges and late fees in certain  circumstances  notwithstanding  contrary state
law,  effective  with  respect  to loans  originated  on or after  July 1, 2003.
However,  the OTS's ruling does not retroactively affect loans originated before
July 1, 2003.

        Some  of  the  Commercial,  Multifamily  and  Mixed-Use  Mortgage  Loans
included in a trust will include a  "debt-acceleration  " clause,  which permits
the lender to accelerate the full debt upon a monetary or nonmonetary default of
the  borrower.  The courts of all states  will  enforce  clauses  providing  for
acceleration  in the event of a material  payment default after giving effect to
any appropriate notices. The courts of any state,  however, may refuse to permit
foreclosure  of a  mortgage  or  deed  of  trust  when  an  acceleration  of the
indebtedness  would be inequitable or

                                       91



unjust  or the  circumstances  would  render  the  acceleration  unconscionable.
Furthermore, in some states, the borrower may avoid foreclosure and reinstate an
accelerated  loan by  paying  only  the  defaulted  amounts  and the  costs  and
attorneys' fees incurred by the lender in collecting such defaulted payments.

SUBORDINATE FINANCING

        Where a borrower  encumbers  mortgaged  property with one or more junior
liens, the senior lender is subjected to additional risks, such as:

        o   The  borrower  may  have  difficulty  repaying  multiple  loans.  In
            addition,  if the junior loan  permits  recourse to the borrower (as
            junior  loans often do) and the senior loan does not, a borrower may
            be more  likely to repay sums due on the  junior  loan than those on
            the senior loan.

        o   Acts of the senior lender that prejudice the junior lender or impair
            the junior  lender's  security may create a superior equity in favor
            of the junior  lender.  For example,  if the borrower and the senior
            lender  agree  to an  increase  in the  principal  amount  of or the
            interest rate payable on the senior loan, the senior lender may lose
            its priority to the extent any existing  junior  lender is harmed or
            the borrower is additionally burdened.

        o   If the  borrower  defaults on the senior loan and/or any junior loan
            or loans,  the existence of junior loans and actions taken by junior
            lenders can impair the security  available to the senior  lender and
            can  interfere  with or delay the  taking  of  action by the  senior
            lender.  Moreover,  the bankruptcy of a junior lender may operate to
            stay foreclosure or similar proceedings by the senior lender.

APPLICABILITY OF USURY LAWS

        Title V of the Depository Institutions Deregulation and Monetary Control
Act of 1980,  enacted in March  1980  ("Title  V"),  provides  that state  usury
limitations  will not apply to some types of  residential  first  mortgage loans
originated  by lenders  after March 31, 1980. A similar  federal  statute was in
effect for mortgage loans made during the first three months of 1980. The Office
of Thrift  Supervision  is  authorized  to issue  rules and  regulations  and to
publish  interpretations  governing  implementation  of  Title  V.  The  statute
authorized any state to reimpose interest rate limits by adopting,  before April
1, 1983, a law or constitutional provision that expressly rejects application of
the federal law. In addition,  even where Title V is not so rejected,  any state
is authorized by the law to adopt a provision  limiting discount points or other
charges on mortgage  loans  covered by Title V. Some states have taken action to
reimpose interest rate limits and/or to limit discount points or other charges.

        The depositor believes that a court interpreting Title V would hold that
residential  first  mortgage  loans that are  originated  on or after January 1,
1980,  are  subject to federal  preemption.  Therefore,  in a state that has not
taken  the  requisite  action  to  reject  application  of Title V or to adopt a
provision  limiting discount points or other charges before origination of those
mortgage loans,  any limitation  under that state's usury law would not apply to
those mortgage loans.

        In any state in which application of Title V has been expressly rejected
or a provision limiting discount points or other charges is adopted, no mortgage
loan  originated  after  the date of that  state  action  will be  eligible  for
inclusion in an issuing  entity  unless (1) the mortgage  loan  provides for the
interest rate, discount points and charges as are permitted in that state or (2)
the mortgage loan  provides that its terms will be construed in accordance  with
the laws of another

                                       92



state under which the interest  rate,  discount  points and charges would not be
usurious and the  borrower's  counsel has rendered an opinion that the choice of
law provision would be given effect.

        Statutes differ in their provisions as to the consequences of a usurious
loan.  One group of statutes  requires  the lender to forfeit the  interest  due
above the applicable limit or impose a specified  penalty.  Under this statutory
scheme,  the  borrower  may cancel the  recorded  mortgage or deed of trust upon
paying its debt with lawful interest, and the lender may foreclose, but only for
the debt plus lawful  interest.  A second  group of statutes is more  severe.  A
violation  of  this  type  of  usury  law  results  in the  invalidation  of the
transaction,  thus  permitting  the borrower to cancel the recorded  mortgage or
deed of trust without any payment or prohibiting the lender from foreclosing.

ALTERNATIVE MORTGAGE INSTRUMENTS

        Alternative  mortgage  instruments,  including  adjustable rate mortgage
loans and early ownership mortgage loans,  originated by non-federally chartered
lenders  have  historically  been  subject to a variety of  restrictions.  Those
restrictions  differed  from  state  to  state,  resulting  in  difficulties  in
determining whether a particular alternative mortgage instrument originated by a
state-chartered lender was in compliance with applicable law. These difficulties
were alleviated  substantially as a result of the enactment of Title VIII of the
Garn-St.  Germain Act ("Title VIII"). Title VIII provides that,  notwithstanding
any state law to the contrary,  state-chartered  banks may originate alternative
mortgage   instruments  in  accordance  with  regulations   promulgated  by  the
Comptroller of the Currency with respect to origination of alternative  mortgage
instruments  by national  banks;  state-chartered  credit  unions may  originate
alternative mortgage  instruments in accordance with regulations  promulgated by
the  National  Credit  Union  Administration  with  respect  to  origination  of
alternative  mortgage  instruments  by  federal  credit  unions;  and all  other
non-federally chartered housing creditors, including state-chartered savings and
loan  associations,  state-chartered  savings banks and mutual savings banks and
mortgage banking companies,  may originate  alternative  mortgage instruments in
accordance with the regulations promulgated by the Federal Home Loan Bank Board,
predecessor to the Office of Thrift Supervision,  with respect to origination of
alternative mortgage instruments by federal savings and loan associations. Title
VIII provides that any state may reject applicability of the provisions of Title
VIII by adopting,  before  October 15, 1985, a law or  constitutional  provision
expressly  rejecting the  applicability  of those  provisions.  Some states have
taken that action.

SERVICEMEMBERS' CIVIL RELIEF ACT

        Under the terms of the  Servicemembers'  Civil  Relief  Act and  similar
state and local laws (the "Relief Act"), a borrower who enters military  service
after the origination of the borrower's  mortgage loan (including a borrower who
was in reserve  status and is called to active  duty  after  origination  of the
mortgage loan) may not be charged interest (including fees and charges) above an
annual rate of 6% during the period of the borrower's active duty status, unless
a court orders otherwise upon application of the lender.  The Relief Act applies
to borrowers who are members of the Army,  Navy,  Air Force,  Marines,  National
Guard,  Reserves,  Coast Guard and officers of the U.S.  Public  Health  Service
assigned to duty with the military.  Because the Relief Act applies to borrowers
who enter military service (including  reservists who are called to active duty)
after  origination of the related  mortgage loan, no information can be provided
as to the number of loans that may be affected by the Relief Act.

        Application  of  the  Relief  Act  would   adversely   affect,   for  an
indeterminate  period of time,  the  ability of the  servicer  to  collect  full
amounts of interest on some of the mortgage  loans.  Any  shortfalls in interest
collections  resulting from the  application of the Relief Act would result in a
reduction of the amounts  distributable  to the holders of the related series of
Notes or  Certificates,  as  applicable,  and would not be covered by  advances.
These  shortfalls  will be covered by the

                                       93



credit  support  provided  in  connection  with the  Notes or  Certificates,  as
applicable,  only  to the  extent  provided  in the  prospectus  supplement.  In
addition,  the Relief Act imposes  limitations  that would impair the ability of
the  servicer to foreclose on an affected  mortgage  loan during the  borrower's
period  of  active  duty  status,  and,  under  some  circumstances,  during  an
additional  three month period  thereafter.  Thus, if an affected  mortgage loan
goes into default, there may be delays and losses occasioned thereby.

FORFEITURES IN DRUG AND RICO PROCEEDINGS

        Federal  law  provides  that  property  owned by  persons  convicted  of
drug-related  crimes or of criminal  violations of the Racketeer  Influenced and
Corrupt  Organizations  ("RICO")  statute can be seized by the government if the
property was used in, or purchased  with the  proceeds of, those  crimes.  Under
procedures  contained in the Comprehensive Crime Control Act of 1984 (the "Crime
Control Act"), the government may seize the property even before conviction. The
government must publish notice of the forfeiture  proceeding and may give notice
to all parties "known to have an alleged  interest in the  property,"  including
the holders of mortgage loans.

        A lender may avoid  forfeiture  of its  interest  in the  property if it
establishes  that: (1) its mortgage was executed and recorded before  commission
of the crime upon which the  forfeiture is based,  or (2) the lender was, at the
time of execution of the  mortgage,  "reasonably  without cause to believe" that
the  property was used in, or  purchased  with the proceeds of,  illegal drug or
RICO activities.

COMMERCIAL, MULTIFAMILY AND MIXED USE LOANS

        The market value of any Commercial,  Multifamily or Mixed-Use  Mortgaged
Property obtained in foreclosure or by deed in lieu of foreclosure will be based
substantially  on the operating  income  obtained from renting the commercial or
dwelling units, the sale price, the value of any alternative uses, or such other
factors as are considered by the originator.  Because a default on a Commercial,
Multifamily  or  Mixed-Use  Mortgage  Loan is  likely to have  occurred  because
operating income, net of expenses, is insufficient to make debt service payments
on such  mortgage  loan,  it can be  anticipated  that the market  value of such
property  will  be less  than  was  anticipated  when  such  mortgage  loan  was
originated.  To the extent that the equity in the  property  does not absorb the
loss in market value and such loss is not covered by other credit enhancement, a
loss may be  experienced.  With respect to any  Multifamily  Mortgaged  Property
consisting of an apartment  building owned by a cooperative,  the  cooperative's
ability to meet debt service  obligations  on the mortgage  loan, as well as all
other  operating  expenses,  will be  dependent  in large part on the receipt of
maintenance payments from the  tenant-stockholders.  Unanticipated  expenditures
may  in  some   cases   have  to  be  paid  by   special   assessments   of  the
tenant-stockholders.  The cooperative's  ability to pay the principal balance of
the  mortgage  loan at  maturity  may  depend on its  ability to  refinance  the
mortgage loan. The  depositor,  the seller and the master  servicer will have no
obligation to provide refinancing for any such mortgage.

        In most  states,  hotel and motel  room  rates are  considered  accounts
receivable  under the UCC. Room rates are  generally  pledged by the borrower as
additional  security for the loan when a mortgage  loan is secured by a hotel or
motel. In general, the lender must file financing statements in order to perfect
its security interest in the room rates and must file  continuation  statements,
generally every five years, to maintain that perfection.  Mortgage loans secured
by hotels or motels may be included in the trust even if the  security  interest
in the room rates was not perfected or the requisite UCC filings were allowed to
lapse. A lender will  generally be required to commence a foreclosure  action or
otherwise  take  possession  of the  property  in order to enforce its rights to
collect  the room rates  following  a  default,  even if the  lender's  security
interest in room rates is perfected under applicable nonbankruptcy law.

                                       94



        In the bankruptcy setting,  the lender will be stayed from enforcing its
rights to  collect  hotel and motel  room  rates.  However,  the room rates will
constitute cash collateral and cannot be used by the bankrupt borrower without a
hearing or the lender's  consent,  or unless the  lender's  interest in the room
rates is given adequate protection.

        For purposes of the  foregoing,  the adequate  protection  may include a
cash  payment  for  otherwise   encumbered   funds  or  a  replacement  lien  on
unencumbered property, in either case equal in value to the amount of room rates
that the bankrupt borrower proposes to use.

LEASES AND RENTS

        Some of the  Commercial,  Multifamily  and Mixed-Use  Mortgage Loans are
secured by an  assignment  of leases (each , a "lease") and rents of one or more
lessees (each, a "lessee"),  either through a separate document of assignment or
as incorporated in the mortgage. Under such assignments,  the borrower under the
mortgage loan typically assigns its right,  title and interest as landlord under
each lease and the income  derived  therefrom to the lender,  while  retaining a
license  to  collect  the  rents  for so long as there is no  default  under the
mortgage loan  documentation.  The manner of perfecting the lender's interest in
rents may  depend on whether  the  borrower's  assignment  was  absolute  or one
granted as  security  for the loan.  Failure to properly  perfect  the  lender's
interest  in rents may  result in the loss of a  substantial  pool of funds that
otherwise  could serve as a source of repayment  for the loan.  In the event the
borrower  defaults,  the  license  terminates  and the lender may be entitled to
collect  rents.  Some state laws may  require  that to perfect  its  interest in
rents,  the lender must take  possession of the property  and/or obtain judicial
appointment of a receiver before becoming entitled to collect the rents. Lenders
that actually take possession of the property,  however,  may incur  potentially
substantial  risks  attendant  to being a mortgagee  in  possession.  Such risks
include liability for  environmental  clean-up costs and other risks inherent to
property  ownership.  In addition,  if  bankruptcy  or similar  proceedings  are
commenced by or in respect of the borrower,  the lender's ability to collect the
rents may be adversely affected. In the event of borrower default, the amount of
rent the lender is able to collect from the tenants can significantly affect the
value of the lender's security interest.

AMERICANS WITH DISABILITIES ACT

        Under Title III of the Americans with Disabilities Act of 1990 and rules
promulgated   thereunder   (collectively,   the   "ADA"),   owners   of   public
accommodations  (such  as  hotels,  restaurants,  shopping  centers,  hospitals,
schools and social service center  establishments) must remove architectural and
communication  barriers that are  structural  in nature from existing  places of
public accommodation to the extent "readily achievable." In addition,  under the
ADA, alterations to a place of public accommodation or a commercial facility are
to be made so that, to the maximum extent  feasible,  such altered  portions are
readily  accessible  to  and  useable  by  disabled  individuals.  The  "readily
achievable"  standard  takes into account,  among other  factors,  the financial
resources of the affected site, owner,  landlord or other applicable  person. In
addition to imposing a possible financial burden on the borrower in its capacity
as owner or landlord, the ADA may also impose such requirements on a foreclosing
lender who  succeeds  to the  interest  of the  borrower  as owner or  landlord.
Furthermore, because the "readily achievable" standard may vary depending on the
financial condition of the owner or landlord, a foreclosing secured party who is
financially more capable than the borrower of complying with the requirements of
the ADA may be subject to more  stringent  requirements  than those to which the
borrower is subject.

                     CERTAIN LEGAL ASPECTS OF THE CONTRACTS

        The  following  discussion  contains  summaries,  which are  general  in
nature, of certain legal matters relating to the contracts.  Because these legal
aspects are governed  primarily by applicable  state law,  which laws may differ
substantially, the summaries do not purport to be complete nor to

                                       95



reflect  the laws of any  particular  state,  nor to  encompass  the laws of all
states in which the security for the  contracts is situated.  The  summaries are
qualified in their entirety by reference to the  appropriate  laws of the states
in which contracts may be originated.

GENERAL

        As a result of the  assignment  of the  contracts  to the  trustee,  the
trustee will succeed  collectively  to all of the rights  including the right to
receive  payment on the  contracts,  of the obligee  under the  contracts.  Each
contract evidences both

                (a)     the  obligation  of  the  borrower  to  repay  the  loan
        evidenced thereby, and

                (b)     the grant of a  security  interest  in the  manufactured
        home to secure  repayment of the loan.  Aspects of both  features of the
        contracts are described more fully below.

        The  contracts  generally  are "chattel  paper" as defined in the UCC in
effect in the states in which the manufactured  homes initially were registered.
Pursuant to the UCC, the sale of chattel paper is treated in a manner similar to
perfection of a security  interest in chattel paper.  Under the  agreement,  the
servicer will transfer physical  possession of the contracts to the trustee.  In
addition,  the servicer  will make an  appropriate  filing of a UCC-1  financing
statement in the appropriate states to give notice of the trustee's ownership of
the  contracts.  The  contracts  will be stamped or marked  otherwise to reflect
their  assignment  from the  depositor  to the  trustee  only if provided in the
prospectus supplement.  Therefore, if, through negligence, fraud or otherwise, a
subsequent  purchaser  were able to take  physical  possession  of the contracts
without notice of the assignment,  the trustee's  interest in contracts could be
defeated.

SECURITY INTERESTS IN THE MANUFACTURED HOMES

        The  manufactured  homes securing the contracts may be located in all 50
states,  Security  interests in  manufactured  homes may be perfected  either by
notation of the secured  party's lien on the certificate of title or by delivery
of the  required  documents  and  payment  of a fee to the state  motor  vehicle
authority,  depending on state law. In some nontitle states, perfection pursuant
to the  provisions  of the UCC is  required.  The asset  seller may effect  that
notation or delivery of the required  documents and fees, and obtain  possession
of the certificate of title, as appropriate under the laws of the state in which
any manufactured home securing a manufactured housing conditional sales contract
is registered.  In the event the asset seller fails,  due to clerical  error, to
effect that notation or delivery, or files the security interest under the wrong
law, the asset  seller may not have a first  priority  security  interest in the
manufactured home securing a contract.  As manufactured homes have become larger
and often have been  attached to their sites  without any apparent  intention to
move them, courts in many states have held that manufactured  homes,  under some
circumstances,  may become subject to real estate title and recording laws. As a
result, a security interest in a manufactured home could be rendered subordinate
to the  interests  of other  parties  claiming  an  interest  in the home  under
applicable state real estate law.

        To perfect a security  interest in a manufactured home under real estate
laws,  the holder of the  security  interest  must file either a fixture  filing
under the provisions of the UCC or a real estate  mortgage under the real estate
laws of the state where the home is located.  These  filings must be made in the
real  estate   records   office  of  the  county  where  the  home  is  located.
Substantially all of the contracts contain  provisions  prohibiting the borrower
from  permanently  attaching the  manufactured  home to its site. So long as the
borrower  does  not  violate  this  agreement,   a  security   interest  in  the
manufactured  home will be governed by the certificate of title laws or the UCC,
and the notation of the  security  interest on the  certificate  of title or the
filing of a UCC financing  statement  will be effective to maintain the priority
of the security interest in the manufactured

                                       96



home.  If,  however,  a manufactured  home is permanently  attached to its site,
other parties could obtain an interest in the manufactured home that is prior to
the security interest originally retained by the asset seller and transferred to
the depositor.  For a series of securities and if so described in the prospectus
supplement,  the servicer may be required to perfect a security  interest in the
manufactured  home under  applicable real estate laws. The warranting party will
represent  that as of the date of the sale to the  depositor  it has  obtained a
perfected first priority security interest by proper notation or delivery of the
required  documents and fees for  substantially  all of the  manufactured  homes
securing the contracts.

        The  depositor  will cause the security  interests  in the  manufactured
homes to be  assigned  to the  trustee  on  behalf of the  securityholders.  The
depositor or the trustee  will amend the  certificates  of title,  or file UCC-3
statements,  to identify the trustee as the new secured party,  and will deliver
the  certificates  of title to the trustee or note  thereon the  interest of the
trustee only if specified in the prospectus supplement.  Accordingly,  the asset
seller,  or other originator of the contracts,  will continue to be named as the
secured party on the certificates of title relating to the  manufactured  homes.
In some  states,  that  assignment  is an effective  conveyance  of the security
interest without amendment of any lien noted on the related certificate of title
and the new secured party  succeeds to servicer's  rights as the secured  party.
However,  in some states,  in the absence of an amendment to the  certificate of
title and the new secured  party  succeeds to  servicer's  rights as the secured
party.  However,  in  some  states,  in  the  absence  of an  amendment  to  the
certificate of title, or the filing of a UCC-3 statement,  the assignment of the
security  interest in the  manufactured  home may not be held  effective  or the
security  interest in the  manufactured  home may not be held  effective  or the
security  interests  may not be perfected and in the absence of that notation or
delivery  to the  trustee,  the  assignment  of  the  security  interest  in the
manufactured home may not be effective against creditors of the asset seller, or
any other  originator of the contracts,  or a trustee in bankruptcy of the asset
seller, or any other originator.

        In  the  absence  of  fraud,  forgery  or  permanent  affixation  of the
manufactured  home to its site by the manufactured home owner, or administrative
error  by state  recording  officials,  the  notation  of the lien of the  asset
seller,  or other  originator of the Contracts,  on the  certificate of title or
delivery of the required  documents  and fees will be  sufficient to protect the
securityholders  against the rights or subsequent  purchasers of a  manufactured
home or  subsequent  lenders who take a security  interest  in the  manufactured
home.  If there are any  manufactured  homes as to which the  security  interest
assigned  to the  trustee is not  perfected,  that  security  interest  would be
subordinate  to, among others,  subsequent  purchasers for value of manufactured
homes and holders of perfected security  interests.  There also exists a risk in
not identifying the trustee as the new secured party on the certificate of title
that, through fraud or negligence, the security interest of the trustee could be
released.

        If the owner of a  manufactured  home moves it to a state other than the
state in which the manufactured home initially is registered,  under the laws of
most  states the  perfected  security  interest in the  manufactured  home would
continue for four months after the relocation  and thereafter  only if and after
the owner re-registers the manufactured home in that state. If the owner were to
relocate  a  manufactured   home  to  another  state  and  not  re-register  the
manufactured  home in that state,  and if steps are not taken to re-perfect  the
trustee's  security  interest  in  that  state,  the  security  interest  in the
manufactured  home would cease to be perfected.  A majority of states  generally
require surrender of a certificate of title to re-register a manufactured  home;
accordingly,  the servicer must surrender possession if it holds the certificate
of  title  to the  manufactured  home  or,  in the  case of  manufactured  homes
registered  in states that provide for notation of lien,  the asset  seller,  or
other originator,  would receive notice of surrender if the security interest in
the  manufactured  home is noted on the certificate of title.  Accordingly,  the
trustee would have the  opportunity to re-perfect  its security  interest in the
manufactured  home in the state of  relocation.  In states that do not require a
certificate of title for  registration of a manufactured  home,  re-registration
could defeat perfection. In the ordinary course of servicing

                                       97



the  manufactured  housing  contracts,   the  servicer  takes  steps  to  effect
re-perfection  upon receipt of notice of re-registration or information from the
borrower as to relocation.

        Similarly, when a borrower under a manufactured housing contract sells a
manufactured home, the servicer must surrender  possession of the certificate of
title or, if it is noted as lienholder on the certificate of title, will receive
notice  as a result  of its lien  noted  thereon  and  accordingly  will have an
opportunity  to  require   satisfaction  of  the  related  manufactured  housing
conditional sales contract before release of the lien. Under the Agreement,  the
servicer is obligated to take those steps,  at the  servicer's  expense,  as are
necessary  to maintain  perfection  of security  interests  in the  manufactured
homes.

        Under  the  laws  of most  states,  liens  for  repairs  performed  on a
manufactured  home and liens for personal property taxes take priority even over
a perfected  security  interest.  The  warranting  party will  represent  in the
agreement  that it has no knowledge  of any of these liens for any  manufactured
home securing payment on any contract.  However,  these liens could arise at any
time  during the term of a  contract.  No notice will be given to the trustee or
securityholders if a lien arises.

ENFORCEMENT OF SECURITY INTERESTS IN THE MANUFACTURED HOMES

        The  servicer on behalf of the  trustee,  to the extent  required by the
related  agreement,  may take action to enforce the trustee's  security interest
with  respect  to  contracts  in  default  by  repossession  and  resale  of the
manufactured  homes  securing  those  defaulted   contracts.   So  long  as  the
manufactured  home has not become subject to the real estate law, a creditor can
repossess a  manufactured  home securing a contract by voluntary  surrender,  by
"self-help"  repossession  that is  "peaceful"  or, in the absence of  voluntary
surrender and the ability to repossess  without breach of the peace, by judicial
process. The holder of a contract must give the debtor a number of days' notice,
which varies from 10 to 30 days  depending on that state,  before  beginning any
repossession.  The UCC  and  consumer  protection  laws  in  most  states  place
restrictions  on  repossession  sales,  including  requiring prior notice to the
debtor and  commercial  reasonableness  in effecting  that sale. The law in most
states also  requires  that the debtor be given notice of any sale before resale
of the unit so that the debtor may redeem at or before that resale. In the event
of repossession and resale of a manufactured home, the trustee would be entitled
to be paid out of the sale proceeds  before the proceeds could be applied to the
payment of the claims of  unsecured  creditors  or the  holders of  subsequently
perfected security interests or, thereafter, to the debtor.

        Under the laws  applicable  in most  states,  a creditor  is entitled to
obtain a deficiency  judgment from a debtor for any  deficiency on  repossession
and resale of the manufactured  home securing the debtor's loan.  However,  some
states impose prohibitions or limitations on deficiency  judgments,  and in many
cases the defaulting borrower would have no assets with which to pay a judgment.

        Other statutory  provisions,  including federal and state bankruptcy and
insolvency laws and general equitable principles, may limit or delay the ability
of a lender to repossess and resell collateral or enforce a deficiency judgment.

SERVICEMEMBERS' CIVIL RELIEF ACT

        The  terms of the  Relief  Act  apply to a  borrower  on a  Contract  as
described  for a borrower on a mortgage  loan under  "Certain  Legal  Aspects of
Mortgage Loans-Civil Act."

                                       98



CONSUMER PROTECTION LAWS

        The so-called  Holder-in-Due-Course rule of the Federal Trade Commission
is  intended  to defeat the  ability  of the  transferor  of a  consumer  credit
contract  that is the seller of goods  which gave rise to the  transaction,  and
some related  lenders and assignees,  to transfer the contract free of notice of
claims by the  debtor  thereunder.  The  effect of this rule is to  subject  the
assignee of the contract to all claims and defenses that the debtor could assert
against  the  seller of goods.  Liability  under this rule is limited to amounts
paid under a contract; however, the borrower also may be able to assert the rule
to set off  remaining  amounts due as a defense  against a claim  brought by the
trustee  against  the  borrower.  Numerous  other  federal  and  state  consumer
protection  laws impose  requirements  applicable to the origination and lending
pursuant to the contracts, including the Truth in Lending Act, the Federal Trade
Commission Act, the Fair Credit Billing Act, the Fair Credit  Reporting Act, the
Equal Credit  Opportunity  Act, the Fair Debt  Collection  Practices Act and the
Uniform  Consumer Credit Code. In the case of some of these laws, the failure to
comply  with  their  provisions  may affect the  enforceability  of the  related
contract.

TRANSFERS OF MANUFACTURED HOMES; ENFORCEABILITY OF "DUE-ON-SALE" CLAUSES

        The contracts, in general,  prohibit the sale or transfer of the related
manufactured   homes  without  the  consent  of  the  servicer  and  permit  the
acceleration  of the maturity of the  contracts by the servicer upon any sale or
transfer that is not consented to.  Generally,  it is expected that the servicer
will permit most transfers of manufactured homes and not accelerate the maturity
of the  related  contracts.  In  some  cases,  the  transfer  may be  made  by a
delinquent borrower to avoid a repossession proceeding for a manufactured home.

        In the  case of a  transfer  of a  manufactured  home  after  which  the
servicer  desires to  accelerate  the  maturity  of the  related  contract,  the
servicer's ability to do so will depend on the enforceability under state law of
the due-on-sale clauses applicable to the manufactured homes.  Consequently,  in
some states the servicer may be prohibited  from enforcing a due-on-sale  clause
in respect of some manufactured homes.

APPLICABILITY OF USURY LAWS

        Title V of the Depository Institutions Deregulation and Monetary Control
Act of 1980,  as amended  (Title V),  provides  that,  subject to the  following
conditions,  state usury  limitations will not apply to any loan that is secured
by a first lien on certain kinds of manufactured housing. The contracts would be
covered if they satisfy certain  conditions,  among other things,  governing the
terms of any prepayments,  late charges and deferral fees and requiring a 30-day
notice  period  before  instituting  any action  leading to  repossession  of or
foreclosure on the related unit.

        Title V authorized any state to re-impose  limitations on interest rates
and finance  charges by adopting  before April 1, 1983, a law or  constitutional
provision that expressly rejects  application of the federal law. Fifteen states
adopted a similar law before the April 1, 1983 deadline. In addition, even where
Title V was not so  rejected,  any  state  is  authorized  by the law to adopt a
provision limiting discount points or other charges on loans covered by Title V.
The related asset seller will  represent  that all of the contracts  comply with
applicable usury law.

                   MATERIAL FEDERAL INCOME TAX CONSIDERATIONS

GENERAL

        The following discussion represents the opinions of McKee Nelson LLP and
Thacher  Proffitt & Wood llp as to the material  federal income tax consequences
of the purchase, ownership and

                                       99



disposition  of the Notes or  Certificates,  as  applicable,  offered under this
prospectus.  These  opinions  assume  compliance  with  all  provisions  of  the
Agreements  pursuant  to which the Notes or  Certificates,  as  applicable,  are
issued.  This  discussion is directed  solely to  securityholders  that hold the
Notes or  Certificates,  as applicable,  as capital assets within the meaning of
Section 1221 of the Internal Revenue Code of 1986, as amended (the "Code"),  and
does not  purport to discuss  all federal  income tax  consequences  that may be
applicable to particular categories of investors,  some of which (such as banks,
insurance  companies,  investors  that do not buy in the  original  offering and
foreign investors) may be subject to special rules.  Further, the authorities on
which this discussion, and the opinions referred to below, are based are subject
to change or differing interpretations, which could apply retroactively.

        In addition to the federal  income tax  consequences  described  in this
prospectus,  potential investors are encouraged to consider the state, local and
other tax  consequences,  if any, of the purchase,  ownership and disposition of
the  Notes  or   Certificates,   as   applicable.   See  "State  and  Other  Tax
Considerations." The depositor recommends that securityholders consult their own
tax advisors  concerning the federal,  state, local or other tax consequences to
them of the purchase, ownership and disposition of the Notes or Certificates, as
applicable, offered under this prospectus.

        The following discussion addresses securities of four general types:

        o   securities ("REMIC Securities") representing interests in an issuing
            entity,  or a portion of an issuing  entity,  that the trustee  will
            elect to have treated as a real estate mortgage  investment  conduit
            ("REMIC") under Sections 860A through 860G (the "REMIC  Provisions")
            of the Code;

        o   securities ("Grantor Trust Securities")  representing interests in a
            trust fund (a "Grantor  Trust Fund") as to which no election will be
            made;

        o   securities   ("Partnership    Certificates")   representing   equity
            interests  in a trust fund (a  "Partnership  Trust  Fund")  which is
            treated as a partnership for federal income tax purposes; and

        o   securities  ("Debt  Securities")   representing  indebtedness  of  a
            Partnership  Trust Fund or a trust fund  which is  disregarded  as a
            separate  entity from the owner of its equity for federal income tax
            purposes.

               The   prospectus   supplement   for  each   series  of  Notes  or
        Certificates,  as  applicable,  will  indicate  which  of the  foregoing
        treatments  will  apply to that  series  and,  if a REMIC  election  (or
        elections) will be made for the related  issuing  entity,  will identify
        all "regular  interests"  and  "residual  interests"  in the REMIC.  For
        purposes of this tax discussion,

                1.      references  to a  "securityholder"  or a "holder" are to
                the beneficial owner of a Security,

                2.      references  to "REMIC  Pool" are to an entity or portion
                thereof as to which a REMIC election will be made and

                3.      to the extent  specified in the  prospectus  supplement,
                references to "mortgage loans" include Contracts.

        The  following  discussion  is based in part  upon the  rules  governing
original  issue discount that are set forth in Sections 1271 through 1275 of the
Code and in the Treasury regulations

                                      100



promulgated  thereunder  (the  "OID  Regulations"),  and in part  upon the REMIC
Provisions  and the  Treasury  regulations  promulgated  thereunder  (the "REMIC
Regulations").  In addition,  the OID Regulations do not adequately address some
issues  relevant to, and in some instances  provide that they are not applicable
to, prepayable securities such as the Notes or Certificates, as applicable.

        TAXABLE MORTGAGE POOLS

        Corporate  income tax can be imposed on the net income of some  entities
issuing  non-REMIC debt obligations  secured by real estate mortgages  ("Taxable
Mortgage  Pools").  Any entity  other than a REMIC will be  considered a Taxable
Mortgage Pool if

                (1)     substantially all of the assets of the entity consist of
                debt  obligations  and  more  than  50%  of  those   obligations
                (determined  by  adjusted  tax basis)  consist  of "real  estate
                mortgages,"

                (2)     that entity is the borrower under debt  obligations with
                two or more maturities, and

                (3)     under  the  terms of the debt  obligations  on which the
                entity is the  borrower,  payments on those  obligations  bear a
                relationship to payments on the obligations held by the entity.

Furthermore,  a group of assets  held by an entity  can be treated as a separate
Taxable  Mortgage  Pool if the assets are expected to produce  significant  cash
flow that will support one or more of the entity's  issues of debt  obligations.
The depositor  generally  will  structure  offerings of non-REMIC  Securities to
avoid the application of the Taxable Mortgage Pool rules.

REMICs

        CLASSIFICATION OF REMICS

        For each  series  of  REMIC  Securities,  McKee  Nelson  LLP or  Thacher
Proffitt & Wood LLP (as  applicable,  "Federal  Tax  Counsel")  will  deliver an
opinion that, assuming compliance with all provisions of the related pooling and
servicing  agreement,  the related issuing entity (or each applicable portion of
the issuing  entity)  will qualify as a REMIC and the REMIC  Securities  offered
with  respect  thereto  will be  considered  to evidence  ownership  of "regular
interests"   ("Regular   Securities")   or   "residual   interests"   ("Residual
Securities") in the REMIC within the meaning of the REMIC Provisions.

        In order for the REMIC Pool to qualify as a REMIC, there must be ongoing
compliance on the part of the REMIC Pool with the  requirements set forth in the
Code.  The REMIC Pool must fulfill an asset test,  which  requires  that no more
than a de minimis  portion of the assets of the REMIC  Pool,  as of the close of
the third calendar month  beginning  after the "Startup Day" (which for purposes
of this  discussion is the date of issuance of the REMIC  Securities) and at all
times  thereafter,  consist  of assets  other  than  "qualified  mortgages"  and
"permitted investments." The REMIC Regulations provide a safe harbor pursuant to
which the de minimis  requirement will be met if at all times the total adjusted
basis of the nonqualified  assets is less than 1% of the total adjusted basis of
all the REMIC  Pool's  assets.  An entity that fails to meet the safe harbor may
nevertheless  demonstrate  that it holds no more  than a de  minimis  amount  of
nonqualified assets. A REMIC Pool also must provide "reasonable arrangements" to
prevent its residual  interests from being held by "disqualified  organizations"
or  agents of  "disqualified  organizations"  and must  furnish  applicable  tax
information to transferors or agents that violate this requirement.  The pooling
and  servicing  agreement  for each  series  of REMIC  Securities  will  contain
provisions

                                      101



meeting   these   requirements.   See   "--Taxation   of  Owners   of   Residual
Securities--Tax-Related     Restrictions     on     Transfer     of     Residual
Securities--Disqualified Organizations" below.

        A qualified mortgage is any obligation that is principally secured by an
interest  in real  property  and that is  transferred  to the REMIC  Pool on the
Startup  Day,  is  purchased  by the  REMIC  Pool  within a  three-month  period
thereafter pursuant to a fixed price contract in effect on the Startup Day or is
attributable to an advance made to the mortgagor  pursuant to the original terms
of the  obligation  and is  purchased  by the REMIC  pursuant  to a fixed  price
contract  in  effect on the  Startup  Day.  Qualified  mortgages  include  whole
mortgage loans and,  certain  certificates  of beneficial  interest in a grantor
trust that holds mortgage loans and regular  interests in another REMIC, such as
lower-tier  regular interests in a tiered REMIC. The REMIC  Regulations  specify
that loans secured by timeshare  interests,  shares held by a tenant stockholder
in a cooperative housing corporation, and manufactured housing that qualifies as
a "single  family  residence"  under Code  Section  25(e)(10)  can be  qualified
mortgages. A qualified mortgage includes a qualified replacement mortgage, which
is any property that would have been treated as a qualified  mortgage if it were
transferred to the REMIC Pool on the Startup Day and that is received either:

                (1)     in  exchange  for  any  qualified   mortgage   within  a
        three-month period from the Startup Day; or

                (2)     in  exchange  for  a  "defective  obligation"  within  a
        two-year period from the Startup Day.

        A "defective obligation" includes:

                (1)     a  mortgage  in  default  or  as  to  which  default  is
        reasonably foreseeable;

                (2)     a mortgage  as to which a  customary  representation  or
        warranty  made at the  time of  transfer  to the  REMIC  Pool  has  been
        breached;

                (3)     a  mortgage  that  was  fraudulently   procured  by  the
        borrower; and

                (4)     a mortgage that was not in fact  principally  secured by
        real  property  (but only if the  sponsor  had a  reasonable  belief the
        mortgage  loan was  principally  secured by real  estate at the time the
        mortgage  was  acquired  by the REMIC and the  mortgage  is  disposed of
        within 90 days of discovery of this defect).

A mortgage loan that is "defective" as described in clause (4) above that is not
sold or, if within two years of the Startup Day,  sold or  exchanged,  within 90
days of discovery, ceases to be a qualified mortgage after that 90-day period.

        Permitted  investments include cash flow investments,  qualified reserve
assets,  and  foreclosure  property.  A cash flow  investment is an  investment,
earning a return in the  nature of  interest,  of  amounts  received  on or with
respect to qualified  mortgages for a temporary period, not exceeding 13 months,
until the next scheduled distribution to holders of interests in the REMIC Pool.
A qualified reserve asset is any intangible property held for investment that is
part of any reasonably  required reserve maintained by the REMIC Pool to provide
for  payments  of  expenses  of the REMIC Pool or amounts  due on the regular or
residual  interests in the event of defaults  (including  delinquencies)  on the
qualified  mortgages,  lower  than  expected  reinvestment  returns,  prepayment
interest  shortfalls  and  other   contingencies.   The  reserve  fund  will  be
disqualified  if more than 30% of the gross  income from the assets in that fund
for the year is derived from the sale or other  disposition of property held for
less than three  months,  unless  required  to prevent a default on the  regular
interests caused by a default on one or more qualified mortgages. A reserve fund
must be reduced "promptly and  appropriately" to the extent no longer reasonably
required.

                                      102



Foreclosure  property is real property  acquired by the REMIC Pool in connection
with the default or imminent  default of a qualified  mortgage and generally may
not be held  for more  than  three  taxable  years  after  the  taxable  year of
acquisition  unless an extension of up to three  additional  years is granted by
the Secretary of the Treasury.

        In addition to the foregoing  requirements,  the various  interests in a
REMIC Pool also must meet specific requirements. All of the interests in a REMIC
Pool  must be  either  of the  following:  (1) one or more  classes  of  regular
interests or (2) a single class of residual interests on which distributions, if
any, are made pro rata.

        o   A regular  interest is an interest in a REMIC Pool that is issued on
            the  Startup  Day with  fixed  terms,  is  designated  as a  regular
            interest,  and  unconditionally  entitles  the  holder to  receive a
            specified  principal amount (or other similar amount),  and provides
            that  interest  payments (or other similar  amounts),  if any, at or
            before  maturity  either  are  payable  based  on a fixed  rate or a
            qualified  variable  rate,  or  consist of a  specified,  nonvarying
            portion  of the  interest  payments  on  qualified  mortgages.  That
            specified  portion may consist of a fixed number of basis points,  a
            fixed  percentage  of the total  interest,  or a qualified  variable
            rate,  inverse  variable  rate or  difference  between  two fixed or
            qualified variable rates on some or all of the qualified  mortgages.
            The specified  principal  amount of a regular interest that provides
            for interest payments consisting of a specified,  nonvarying portion
            of interest payments on qualified mortgages may be zero.

        o   A  residual  interest  is an  interest  in a REMIC Pool other than a
            regular  interest  that is  issued  on the  Startup  Day and that is
            designated as a residual interest.

        An interest in a REMIC Pool may be treated as a regular interest even if
payments of principal  for that interest are  subordinated  to payments on other
regular  interests or the residual interest in the REMIC Pool, and are dependent
on the absence of defaults or delinquencies on qualified  mortgages or permitted
investments,  lower than reasonably  expected returns on permitted  investments,
unanticipated  expenses  incurred  by the  REMIC  Pool  or  prepayment  interest
shortfalls. Accordingly, except as disclosed in a related prospectus supplement,
in the opinion of Federal Tax Counsel,  the Regular  Securities of a series will
constitute one or more classes of regular interests, and the Residual Securities
for that series will  constitute a single class of residual  interests  for each
REMIC Pool.

        If an entity  electing to be treated as a REMIC fails to comply with one
or more of the  ongoing  requirements  of the Code for that  status  during  any
taxable  year,  the Code provides that the entity will not be treated as a REMIC
for that year and  thereafter.  In that  event,  that entity may be taxable as a
corporation under Treasury regulations, and the related REMIC Securities may not
be accorded the status or given the tax treatment described below.  Although the
Code authorizes the Treasury Department to issue regulations providing relief in
the  event  of an  inadvertent  termination  of  REMIC  status,  none  of  these
regulations have been issued. Any relief provided,  moreover, may be accompanied
by sanctions,  such as the  imposition of a corporate tax on all or a portion of
the issuing  entity's income for the period in which the  requirements  for that
status are not  satisfied.  The pooling and  servicing  agreement for each REMIC
Pool will include provisions designed to maintain the issuing entity's status as
a REMIC under the REMIC Provisions. It is not anticipated that the status of any
issuing entity as a REMIC will be terminated.

        CHARACTERIZATION OF INVESTMENTS IN REMIC SECURITIES

        The REMIC  Securities will be treated as "real estate assets" within the
meaning of Section  856(c)(4)(A)  of the Code and  assets  described  in Section
7701(a)(19)(C)  of the Code in the same  proportion that the assets of the REMIC
Pool underlying these Notes or Certificates, as applicable,

                                      103



would be so  treated.  Moreover,  if 95% or more of the assets of the REMIC Pool
qualify for either of the  foregoing  treatments  at all times during a calendar
year, the REMIC  Securities will qualify for the  corresponding  status in their
entirety for that calendar year.

        Interest  (including  original issue discount) on the Regular Securities
and  income  allocated  to the class of  Residual  Securities  will be  interest
described  in Section  856(c)(3)(B)  of the Code to the extent that the Notes or
Certificates,  as  applicable,  are treated as "real estate  assets"  within the
meaning of Section 856(c)(4)(A) of the Code. In addition, the Regular Securities
generally will be "qualified mortgages" within the meaning of Section 860G(a)(3)
of the Code if  transferred  to another REMIC on its Startup Day in exchange for
regular or residual interests in the REMIC.

        The assets of the REMIC  Pool will  include,  in  addition  to  mortgage
loans,  payments  on  mortgage  loans  held  pending  distribution  on the REMIC
Securities  and property  acquired by  foreclosure  held pending  sale,  and may
include amounts in reserve accounts.  It is unclear whether property acquired by
foreclosure  held  pending  sale  and  amounts  in  reserve  accounts  would  be
considered  to be part of the mortgage  loans,  or whether  those assets (to the
extent not invested in assets  described in the  foregoing  sections)  otherwise
would  receive the same  treatment as the mortgage  loans for purposes of all of
the foregoing sections. The REMIC Regulations do provide, however, that payments
on mortgage loans held pending  distribution are considered part of the mortgage
loans for purposes of Section 856(c)(4)(A) of the Code. Furthermore, foreclosure
property   generally   will  qualify  as  "real  estate  assets"  under  Section
856(c)(4)(A) of the Code.

        TIERED REMIC STRUCTURES

        For some series of REMIC Securities,  two or more separate elections may
be made to treat  designated  portions of the related  issuing  entity as REMICs
("Tiered  REMICs") for federal income tax purposes.  Upon the issuance of any of
these series of REMIC  Securities,  Federal Tax Counsel will deliver its opinion
that,  assuming  compliance  with all  provisions  of the  related  pooling  and
servicing  agreement,  the Tiered  REMICs  will each  qualify as a REMIC and the
respective  interests issued by each Tiered REMIC will be considered to evidence
ownership of regular interests or residual interests in the related REMIC within
the meaning of the REMIC Provisions.

        Solely for purposes of determining  whether the REMIC Securities will be
"real estate assets" within the meaning of Section  856(c)(4)(A) of the Code and
"loans secured by an interest in real property" under Section  7701(a)(19)(C) of
the Code, and whether the income on those Notes or Certificates,  as applicable,
is interest  described in Section  856(c)(3)(B)  of the Code,  the Tiered REMICs
will be treated as one REMIC.

        TAXATION OF OWNERS OF REGULAR SECURITIES

(1)     General

        Except as otherwise  indicated  herein,  the Regular  Securities will be
treated for federal income tax purposes as debt  instruments  that are issued by
the REMIC and not as  beneficial  interests in the REMIC or the REMIC's  assets.
Interest,  original issue  discount,  and market discount (other than de minimis
original  issue  discount  market  discount the holder does not elect to include
currently) on a Regular  Security will be treated as ordinary income to a holder
of the Regular Security (the "Regular  Securityholder"),  and principal payments
(other  than  payments  treated as  payments  of  accrued  market  discount  not
previously included in income) on a Regular Security will be treated as a return
of capital to the extent of the  Regular  Securityholder's  basis in the Regular
Security allocable thereto.  Regular Securityholders must use the accrual method
of  accounting  with regard to Regular  Securities,  regardless of the method of
accounting otherwise used by that Regular Securityholder.

                                      104



        Payments of interest on Regular Securities may be based on a fixed rate,
a variable  rate as  permitted  by the REMIC  Regulations,  or may  consist of a
specified  portion of the interest  payments on qualified  mortgages  where such
portion does not vary during the period the Regular Security is outstanding. The
definition of a variable rate for purposes of the REMIC  Regulations is based on
the definition of a qualified  floating rate for purposes of the rules governing
original  issue  discount  set  forth  in  the  OID  Regulations,  with  certain
modifications   and  permissible   variations.   See  "--Variable  Rate  Regular
Securities"  below for a discussion of the  definition  of a qualified  floating
rate for purposes of the OID Regulations.  A qualified floating rate, as defined
above for purposes of the REMIC Regulations (a "REMIC qualified floating rate"),
qualifies as a variable rate for purposes of the REMIC Regulations if such REMIC
qualified  floating  rate  is set at a  "current  rate"  as  defined  in the OID
Regulations.  In addition, a rate equal to the highest,  lowest or an average of
two or more REMIC  qualified  floating  rates  qualifies as a variable  rate for
REMIC  purposes.  A Regular  Security  may also have a variable  rate based on a
weighted average of the interest rates on some or all of the qualified mortgages
held by the REMIC where each  qualified  mortgage taken into account has a fixed
rate or a  variable  rate  that is  permissible  under  the  REMIC  Regulations.
Further,  a  Regular  Security  may have a rate that is the  product  of a REMIC
qualified floating rate or a weighted average rate and a fixed multiplier,  is a
constant  number of basis  points more or less than a REMIC  qualified  floating
rate or a weighted  average  rate,  or is the product,  plus or minus a constant
number of basis points, of a REMIC qualified floating rate or a weighted average
rate  and a fixed  multiplier.  An  otherwise  permissible  variable  rate for a
Regular  Security,  described above, will not lose its character as such because
it is subject to a floor or a cap,  including  a "funds  available  cap" as that
term is defined in the REMIC  Regulations.  Lastly,  a Regular  Security will be
considered as having a permissible  variable rate if it has a fixed or otherwise
permissible  variable  rate  during one or more  payment or accrual  periods and
different fixed or otherwise  permissible variable rates during other payment or
accrual periods.

(2)     Original Issue Discount

        Accrual  Securities will be, and other classes of Regular Securities may
be, issued with  "original  issue  discount"  within the meaning of Code Section
1273(a).  Holders of any Class or Subclass of Regular Securities having original
issue discount generally must include original issue discount in ordinary income
for federal  income tax purposes as it accrues,  in  accordance  with a constant
yield method that takes into account the compounding of interest,  in advance of
the receipt of the cash attributable to that income. The following discussion is
based in part on the OID  Regulations  and in part on the  provisions of the Tax
Reform Act of 1986 (the "1986 Act").  Regular  Securityholders  should be aware,
however,  that the OID Regulations do not adequately  address some of the issues
relevant  to, and in some  instances  provide that they are not  applicable  to,
securities,  such as the Regular Securities. To the extent that those issues are
not addressed in the  regulations,  the Seller intends to apply the  methodology
described in the Conference  Committee  Report to the 1986 Act. No assurance can
be provided that the Internal Revenue Service will not take a different position
as to those matters not currently  addressed by the OID  Regulations.  Moreover,
the OID  Regulations  include an anti-abuse  rule allowing the Internal  Revenue
Service  to  apply  or  depart  from  the OID  Regulations  where  necessary  or
appropriate  to  ensure  a  reasonable  tax  result  because  of the  applicable
statutory provisions. A tax result will not be considered unreasonable under the
anti-abuse rule in the absence of an expected  substantial effect on the present
value of a taxpayer's tax liability.  Investors are advised to consult their own
tax advisors as to the  discussion in the OID  Regulations  and the  appropriate
method for  reporting  interest  and  original  issue  discount  for the Regular
Securities.

        In limited  circumstances  multiple Regular Securities can be aggregated
and treated as a single debt  instrument  for  purposes of applying the original
issue  discount  rules.  Otherwise  each Regular  Security  will be treated as a
single  installment  obligation for purposes of  determining  the original issue
discount  includible in a Regular  Securityholder's  income. The total amount of
original  issue  discount  on a Regular  Security  is the excess of the  "stated
redemption price at

                                      105



maturity" of the Regular  Security over its "issue  price." The issue price of a
Class of Regular Securities offered pursuant to this prospectus generally is the
first  price at which a  substantial  amount of that Class is sold to the public
(excluding bond houses,  brokers and  underwriters).  Although unclear under the
OID  Regulations,  it is anticipated that the trustee will treat the issue price
of a Class as to which there is no substantial sale as of the issue date or that
is retained  by the  depositor  as the fair market  value of the Class as of the
issue date. The issue price of a Regular  Security also includes any amount paid
by an initial  Regular  Securityholder  for accrued  interest  that relates to a
period  before  the issue  date of the  Regular  Security,  unless  the  Regular
Securityholder  elects on its federal  income tax return to exclude  that amount
from the issue price and to recover it on the first Distribution Date.

        The stated  redemption  price at maturity of a Regular  Security  always
includes the original  principal amount of the Regular  Security,  but generally
will not include  distributions  of interest if those  distributions  constitute
"qualified  stated  interest."  Under  the  OID  Regulations,  qualified  stated
interest  generally means interest payable at a single fixed rate or a qualified
variable rate (as  described  below),  provided  that the interest  payments are
unconditionally  payable at intervals of one year or less during the entire term
of the Regular Security.  Interest is unconditionally payable only if reasonable
legal  remedies  exist  to  compel  timely  payment  or the  terms  of the  debt
instrument otherwise make the likelihood of late payment (beyond a grace period)
or  non-payment  sufficiently  remote.  Because  there is no  penalty or default
remedy in the case of  nonpayment  of  interest  for a Regular  Security,  it is
possible that no interest on any Class of Regular  Securities will be treated as
qualified  stated interest.  However,  except as provided in the following three
sentences  or in  the  prospectus  supplement,  although  there  is no  guidance
directly addressing the issue, because the underlying mortgage loans provide for
remedies in the event of default it is  anticipated  that the trustee will treat
interest for the Regular Securities as qualified stated interest.  Distributions
of interest on an Accrual  Security,  or on other Regular  Securities  for which
deferred interest will accrue, will not constitute qualified stated interest, in
which case the stated  redemption price at maturity of those Regular  Securities
includes  all  distributions  of  interest as well as  principal  on the Regular
Securities.  Likewise,  although  there is no guidance  directly  addressing the
issue, it is anticipated that the trustee will treat an interest-only Class or a
Class on which  interest  is  substantially  disproportionate  to its  principal
amount  (a  so-called  "super-premium"  Class) as  having  no  qualified  stated
interest.  Where the interval between the issue date and the first  Distribution
Date on a Regular  Security  is shorter  than the  interval  between  subsequent
Distribution  Dates,  the interest  attributable  to the additional days will be
included in the stated redemption price at maturity.

        Under a de minimis rule,  original issue discount on a Regular  Security
will be considered to be zero if the original  issue discount is less than 0.25%
of the stated redemption price at maturity of the Regular Security multiplied by
the weighted average  maturity of the Regular  Security.  For this purpose,  the
weighted  average maturity of the Regular Security is computed as the sum of the
amounts determined by multiplying the number of full years (i.e.,  rounding down
partial  years)  from the issue date until each  distribution  in  reduction  of
stated  redemption price at maturity is scheduled to be made by a fraction,  the
numerator  of which is the amount of each  distribution  included  in the stated
redemption  price at maturity of the Regular  Security  and the  denominator  of
which is the stated  redemption price at maturity of the Regular  Security.  The
Conference  Committee Report to the 1986 Act provides that the schedule of those
distributions  should be  determined  in  accordance  with the  assumed  rate of
prepayment  of  the  mortgage  loans  (the  "Prepayment   Assumption")  and  the
anticipated  reinvestment rate, if any, relating to the Regular Securities.  The
Prepayment  Assumption for a series of Regular  Securities  will be set forth in
the prospectus  supplement.  Holders  generally must report de minimis  original
issue discount pro rata as principal payments are received, and that income will
generally  be capital gain if the Regular  Security is held as a capital  asset.
Under the OID Regulations,  however, Regular Securityholders may elect to accrue
all de minimis original issue discount as well as market

                                      106



discount and market premium,  under the constant yield method. See "-Election to
Treat All Interest Under the Constant Yield Method" below.

        A Regular Securityholder  generally must include in gross income for any
taxable year the sum of the "daily  portions," as defined below, of the original
issue discount on the Regular Security accrued during an accrual period for each
day on which it holds the Regular  Security,  including the date of purchase but
excluding  the date of  disposition.  The trustee will treat the monthly  period
ending on the day before each Distribution Date as the accrual period.  For each
Regular Security, a calculation will be made of the original issue discount that
accrues during each  successive  full accrual period (or shorter period from the
date of original  issue)  that ends on the day before the  related  Distribution
Date on the Regular  Security.  The Conference  Committee Report to the 1986 Act
states  that the rate of accrual of  original  issue  discount is intended to be
based on the Prepayment  Assumption.  The original issue discount  accruing in a
full accrual period would be the excess, if any, of:

                (1)     the sum of:

                        (a)     the  present  value  of  all  of  the  remaining
                        distributions  to be made on the Regular  Security as of
                        the end of that accrual period and

                        (b)     the  distributions  made on the Regular Security
                        during  the  accrual  period  that are  included  in the
                        Regular  Security's stated redemption price at maturity,
                        over

                (2)     the adjusted issue price of the Regular  Security at the
        beginning of the accrual period.

The present  value of the remaining  distributions  referred to in the preceding
sentence is calculated based on:

                (1)     the yield to  maturity  of the  Regular  Security at the
        issue date; and

                (2)     the Prepayment Assumption.

For these  purposes,  the  adjusted  issue  price of a Regular  Security  at the
beginning of any accrual period equals the issue price of the Regular  Security,
increased  by the total  amount  of  original  issue  discount  for the  Regular
Security that accrued in all prior accrual  periods and reduced by the amount of
distributions  included in the Regular  Security's  stated  redemption  price at
maturity  that were made on the Regular  Security in those  prior  periods.  The
original  issue  discount  accruing  during any accrual period (as determined in
this  paragraph)  will then be  divided  by the  number of days in the period to
determine  the daily  portion of  original  issue  discount  for each day in the
period.  For an initial accrual period shorter than a full accrual  period,  the
daily  portions of original  issue  discount must be determined  according to an
appropriate allocation under any reasonable method.

        Under the method  described  above, the daily portions of original issue
discount required to be included in income by a Regular Securityholder generally
will increase to take into account  prepayments  on the Regular  Securities as a
result  of  prepayments  on  the  mortgage  loans  that  exceed  the  Prepayment
Assumption,  and generally  will decrease (but not below zero for any period) if
the  prepayments  are slower  than the  Prepayment  Assumption.  An  increase in
prepayments on the mortgage loans for a series of Regular  Securities can result
in both a change in the  priority  of  principal  payments  for some  Classes of
Regular  Securities  and either an increase or decrease in the daily portions of
original issue discount for those Regular Securities.

                                      107



(3)     Acquisition Premium

        A purchaser of a Regular  Security  having  original issue discount at a
price greater than its adjusted issue price but less than its stated  redemption
price at maturity will be required to include in gross income the daily portions
of the original  issue  discount on the Regular  Security  reduced pro rata by a
fraction,  the  numerator of which is the excess of its purchase  price over the
adjusted issue price and the denominator of which is the excess of the remaining
stated   redemption   price  at  maturity   over  the   adjusted   issue  price.
Alternatively, a purchaser may elect to treat all that acquisition premium under
the constant yield method,  as described below under the heading  "--Election to
Treat All Interest Under the Constant Yield Method" below.

(4)     Variable Rate Regular Securities

        Regular  Securities  may provide for interest  based on a variable rate.
Under the OID  Regulations,  interest  is  treated  as  payable  at a  qualified
variable  rate if,  generally,  (1) the issue price does not exceed the original
principal balance by more than a specified  amount,  (2) it does not provide for
any  principal  payments  that are  contingent,  within  the  meaning of the OID
Regulations,  except as provided in (1),  and (3) the  interest  compounds or is
payable at least annually at current values of

                (a)     one or more "qualified floating rates,"

                (b)     a single fixed rate and one or more  qualified  floating
                        rates,

                (c)     a single "objective rate," or

                (d)     single fixed rate and a single  objective rate that is a
                        "qualified inverse floating rate."

A floating rate is a qualified  floating rate if  variations  can  reasonably be
expected to measure  contemporaneous  variations  in the cost of newly  borrowed
funds.  A multiple  of a  qualified  floating  rate is  considered  a  qualified
floating rate only if the rate is equal to either (a) the product of a qualified
floating  rate and a fixed  multiple that is greater than 0.65 but not more than
1.35 or (b) the product of a qualified  floating rate and a fixed  multiple that
is greater  than 0.65 but not more than 1.35,  increased or decreased by a fixed
rate.  That rate may also be subject to a fixed cap or floor,  or a cap or floor
that is not reasonably  expected as of the issue date to affect the yield of the
instrument significantly.  An objective rate is any rate (other than a qualified
floating rate) that is determined using a single fixed formula and that is based
on objective financial or economic information, provided that the information is
not (1) within the control of the issuer or a related party or (2) unique to the
circumstances of the issuer or a related party.  However, an objective rate does
not include a rate if it is  reasonably  expected that the average value of such
rate  during  the  first  half of the  Regular  Security's  term  will be either
significantly  less than or significantly  greater than the average value of the
rate during the final half of the Regular  Security's term. A qualified  inverse
floating  rate is a rate equal to a fixed rate minus a qualified  floating  rate
that inversely  reflects  contemporaneous  variations in the qualified  floating
rate; an inverse floating rate that is not a qualified inverse floating rate may
nevertheless be an objective  rate. A Class of Regular  Securities may be issued
under this  prospectus  that does not have a qualified  variable  rate under the
foregoing  rules,  for example,  a Class that bears different rates at different
times during the period it is  outstanding  that it is considered  significantly
"front-loaded" or "back-loaded" within the meaning of the OID Regulations. It is
possible that a Class may be considered to bear "contingent interest" within the
meaning  of the OID  Regulations.  The OID  Regulations,  as they  relate to the
treatment of contingent  interest,  are by their terms not applicable to Regular
Securities.  However,  if final regulations dealing with contingent interest for
Regular  Securities  apply the same  principles  as the OID  Regulations,  those
regulations may lead to

                                      108



different  timing  of  income  inclusion  than  would be the case  under the OID
Regulations.  Furthermore,  application  of those  principles  could lead to the
characterization  of gain on the sale of contingent  interest Regular Securities
as ordinary  income.  Investors  are  encouraged  to consult  their tax advisors
regarding the  appropriate  treatment of any Regular  Security that does not pay
interest  at a fixed  rate or  qualified  variable  rate  as  described  in this
paragraph.

        The amount of original issue discount for a Regular  Security  bearing a
qualified  variable rate of interest will accrue in the manner  described  above
under  "--Original  Issue  Discount,"  with the  yield to  maturity  and  future
payments on that Regular  Security  generally to be  determined by assuming that
interest  will be  payable  for the life of the  Regular  Security  based on the
initial rate (or, if different,  the value of the applicable variable rate as of
the pricing  date) for the  relevant  Class,  if the Class  bears  interest at a
qualified  floating rate or qualified inverse floating rate, or based on a fixed
rate which reflects the reasonably expected yield for the relevant Class, if the
Class bears  interest  at an  objective  rate  (other  than a qualified  inverse
floating rate).  However,  the qualified stated interest allocable to an accrual
period will be increased (or decreased) if the interest actually paid during the
accrual  period  exceed (or is less than) the interest  assumed to be paid under
the  rate  just  described.   Unless  required  otherwise  by  applicable  final
regulations,  although there is no guidance directly addressing the issue, it is
anticipated that the trustee will treat interest,  other than variable  interest
on an interest-only or super-premium  Class, as qualified stated interest at the
qualified variable rate.

(5)     Market Discount

        A subsequent  purchaser of a Regular Security also may be subject to the
market  discount rules of Code Sections 1276 through 1278.  Under these sections
and the  principles  applied by the OID  Regulations  in the context of original
issue  discount,  "market  discount"  is the  amount  by which  the  purchaser's
original  basis  in the  Regular  Security  (1)  is  exceeded  by the  remaining
outstanding principal payments and interest payments other than qualified stated
interest  payments  due on a Regular  Security,  or (2) in the case of a Regular
Security having original issue discount, is exceeded by the adjusted issue price
of that Regular Security at the time of purchase.  The purchaser  generally will
be  required  to  recognize  ordinary  income to the  extent of  accrued  market
discount on that  Regular  Security as  distributions  includible  in the stated
redemption price at maturity of the Regular Security are received,  in an amount
not exceeding that distribution. The market discount would accrue in a manner to
be provided in Treasury  regulations and should take into account the Prepayment
Assumption.  The Conference Committee Report to the 1986 Act provides that until
these regulations are issued, the market discount would accrue either (1) on the
basis of a  constant  interest  rate,  or (2) in the  ratio of  stated  interest
allocable to the relevant period to the sum of the interest for that period plus
the remaining interest as of the end of that period, or in the case of a Regular
Security  issued with original  issue  discount,  in the ratio of original issue
discount  accrued  for the  relevant  period  to the sum of the  original  issue
discount  accrued for that period plus the remaining  original issue discount as
of the end of that period.  The  purchaser  also  generally  will be required to
treat a portion of any gain on a sale or  exchange  of the  Regular  Security as
ordinary  income to the  extent of the  market  discount  accrued to the date of
disposition under one of the foregoing methods, less any accrued market discount
previously reported as ordinary income as partial  distributions in reduction of
the stated  redemption  price at maturity were  received.  The purchaser will be
required to defer  deduction of a portion of the excess of the interest  paid or
accrued on  indebtedness  incurred to purchase or carry a Regular  Security over
the interest  distributable on the Regular Security. The deferred portion of the
interest  expense in any  taxable  year  generally  will not exceed the  accrued
market  discount on the Regular  Security for that year.  Any deferred  interest
expense is, in general,  allowed as a deduction not later than the year in which
the related  market  discount  income is recognized  or the Regular  Security is
disposed of.

        As an alternative  to the inclusion of market  discount in income on the
foregoing basis, the Regular Securityholder may elect to include market discount
in income currently as it accrues on

                                      109



all market discount instruments  acquired by the Regular  Securityholder in that
taxable year or  thereafter,  in which case the interest  deferral rule will not
apply.  See  "--Election  to Treat All Interest Under the Constant Yield Method"
below regarding an alternative manner in which that election may be deemed to be
made.  A person  who  purchases  a Regular  Security  at a price  lower than the
remaining  amounts  includible in the stated redemption price at maturity of the
security, but higher than its adjusted issue price, does not acquire the Regular
Security with market  discount,  but will be required to report  original  issue
discount,  appropriately  adjusted  to reflect the excess of the price paid over
the adjusted issue price.

        Market discount for a Regular  Security will be considered to be zero if
the market discount is less than 0.25% of the remaining stated  redemption price
at  maturity  of the Regular  Security  (or,  in the case of a Regular  Security
having  original  issue  discount,  the  adjusted  issue  price of that  Regular
Security)  multiplied by the weighted  average  maturity of the Regular Security
(presumably   determined  as  described  above  in  the  third  paragraph  under
"--Original  Issue Discount"  above)  remaining  after the date of purchase.  It
appears that de minimis market discount would be reported in a manner similar to
de minimis original issue discount. See "--Original Issue Discount" above.

        Treasury regulations implementing the market discount rules have not yet
been issued, and uncertainty exists with respect to many aspects of those rules.
Due to the  substantial  lack of regulatory  guidance with respect to the market
discount rules,  it is unclear how those rules will affect any secondary  market
that  develops  for  a  particular  Class  of  Regular  Securities.  Prospective
investors in Regular Securities are encouraged to consult their own tax advisors
regarding the application of the market discount rules to the Regular Securities
and the elections to include market  discount in income  currently and to accrue
market discount on the basis of the constant yield method.

(6)     Amortizable Premium

        A Regular Security purchased at a cost greater than its remaining stated
redemption  price at maturity  generally  is  considered  to be  purchased  at a
premium. If the Regular Securityholder holds that Regular Security as a "capital
asset" within the meaning of Code Section 1221, the Regular  Securityholder  may
elect  under Code  Section 171 to amortize  the premium  under a constant  yield
method that reflects  compounding  based on the interval between payments on the
Regular  Security.  The  election  will apply to all  taxable  debt  obligations
(including REMIC regular interests) acquired by the Regular  Securityholder at a
premium  held in that  taxable  year or  thereafter,  unless  revoked  with  the
permission of the Internal Revenue Service.  The Conference  Committee Report to
the 1986 Act indicates a Congressional  intent that the same rules that apply to
the accrual of market  discount on  installment  obligations  will also apply to
amortizing bond premium under Code Section 171 on installment obligations as the
Regular  Securities,  although  it is unclear  whether the  alternatives  to the
constant  interest method described above under "Market Discount" are available.
Amortizable  bond  premium  generally  will be treated as an offset to  interest
income on a Regular  Security,  rather than as a separate  deductible  item. See
"--Election  to Treat  All  Interest  Under the  Constant  Yield  Method"  below
regarding  an  alternative  manner in which the Code Section 171 election may be
deemed to be made.

(7)     Election to Treat All Interest Under the Constant Yield Method

        A holder of a debt  instrument  such as a Regular  Security may elect to
treat all interest  that  accrues on the  instrument  using the  constant  yield
method,  with none of the interest being treated as qualified  stated  interest.
For purposes of applying the constant yield method to a debt instrument  subject
to this  election,  (1)  "interest"  includes  stated  interest,  original issue
discount,  de minimis  original issue  discount,  market discount and de minimis
market  discount,  as adjusted by any  amortizable  bond premium or  acquisition
premium and (2) the debt  instrument is treated

                                      110



as if the instrument were issued on the holder's  acquisition date in the amount
of the holder's  adjusted basis  immediately  after  acquisition.  It is unclear
whether, for this purpose,  the initial Prepayment  Assumption would continue to
apply  or if a new  prepayment  assumption  as  of  the  date  of  the  holder's
acquisition  would  apply.  A holder  generally  may make  this  election  on an
instrument  by  instrument  basis or for a class  or group of debt  instruments.
However,  if  the  holder  makes  this  election  for  a  debt  instrument  with
amortizable  bond  premium,  the  holder is deemed  to have  made  elections  to
amortize bond premium  currently as it accrues  under the constant  yield method
for all premium bonds held by the holder in the same taxable year or thereafter.
Alternatively,  if the holder  makes this  election for a debt  instrument  with
market  discount,  the holder is deemed to have made  elections to report market
discount income  currently as it accrues under the constant yield method for all
market  discount  bonds  acquired  by the  holder  in the same  taxable  year or
thereafter.  The election is made on the holder's  federal income tax return for
the year in which the debt instrument is acquired and is irrevocable except with
the  approval of the Internal  Revenue  Service.  Investors  are  encouraged  to
consult  their own tax  advisors  regarding  the  advisability  of  making  this
election.

(8)     Treatment of Losses

        Regular  Securityholders  will be required to report  income for Regular
Securities on the accrual method of accounting,  without giving effect to delays
or reductions in distributions  attributable to defaults or delinquencies on the
mortgage loans,  except to the extent it can be established  that the losses are
uncollectible.  Accordingly,  the holder of a Regular  Security,  particularly a
Subordinate Security, may have income, or may incur a diminution in cash flow as
a result of a default or  delinquency,  but may not be able to take a  deduction
(subject to the discussion below) for the corresponding  loss until a subsequent
taxable  year.  In this  regard,  investors  are  cautioned  that while they may
generally  cease to accrue  interest  income if it  reasonably  appears that the
interest  will be  uncollectible,  the  Internal  Revenue  Service  may take the
position  that original  issue  discount must continue to be accrued in spite of
its  uncollectibility  until the debt  instrument  is  disposed  of in a taxable
transaction  or becomes  worthless in accordance  with the rules of Code Section
166.

        To the  extent the rules of Code  Section  166  regarding  bad debts are
applicable,  it appears that Regular  Securityholders  that are  corporations or
that  otherwise  hold  the  Regular  Securities  in  connection  with a trade or
business  should in general be allowed to deduct as an  ordinary  loss that loss
with  respect to principal  sustained  during the taxable year on account of any
Regular Securities becoming wholly or partially worthless, and that, in general,
Regular  Securityholders  that are not  corporations and do not hold the Regular
Securities in connection with a trade or business should be allowed to deduct as
a short-term  capital loss any loss sustained during the taxable year on account
of a portion of any Regular Securities  becoming wholly worthless.  Although the
matter is not free from doubt,  non-corporate Regular  Securityholders should be
allowed a bad debt  deduction at the time the  principal  balance of the Regular
Securities is reduced to reflect losses  resulting from any liquidated  mortgage
loans.  The Internal  Revenue  Service,  however,  could take the position  that
non-corporate  holders  will be allowed a bad debt  deduction  to reflect  those
losses only after all the mortgage  loans  remaining in the issuing  entity have
been liquidated or the applicable Class of Regular Securities has been otherwise
retired.  The  Internal  Revenue  Service  could also  assert that losses on the
Regular  Securities  are  deductible  based on some other  method that may defer
those deductions for all holders,  such as reducing future cashflow for purposes
of  computing  original  issue  discount.  This may have the effect of  creating
"negative"  original issue  discount that may be deductible  only against future
positive original issue discount or otherwise upon termination of the Class.

        Regular Securityholders are encouraged to consult their own tax advisors
regarding the appropriate timing, amount and character of any loss sustained for
their  Regular  Securities.  While losses  attributable  to interest  previously
reported as income should be deductible as ordinary

                                      111



losses by both corporate and non-corporate holders, the Internal Revenue Service
may take the  position  that  losses  attributable  to  accrued  original  issue
discount  may only be  deducted as capital  losses in the case of  non-corporate
holders who do not hold the Regular  Securities  in  connection  with a trade or
business. Special loss rules may be applicable to banks and thrift institutions.
These  taxpayers  are  advised  to  consult  their tax  advisors  regarding  the
treatment of losses on Regular Securities.

(9)     Sale or Exchange of Regular Securities

        If a Regular  Securityholder sells or exchanges a Regular Security,  the
Regular  Securityholder will recognize gain or loss equal to the difference,  if
any, between the amount received and its adjusted basis in the Regular Security.
The adjusted basis of a Regular Security  generally will equal the original cost
of the Regular Security to the seller,  increased by any original issue discount
or market  discount  previously  included in the  seller's  gross income for the
Regular Security and reduced by amounts included in the stated  redemption price
at maturity of the Regular Security that were previously received by the seller,
by any amortized premium, and by any recognized losses.

        Except as  described  above  regarding  market  discount,  and except as
provided  in this  paragraph,  any  gain or loss on the  sale or  exchange  of a
Regular  Security  realized by an investor  who holds the Regular  Security as a
capital  asset will be capital gain or loss and will be long-term or  short-term
depending  on  whether  the  Regular  Security  has been held for the  long-term
capital gain holding period  (currently,  more than one year). That gain will be
treated as ordinary income

                (1)     if a Regular  Security is held as part of a  "conversion
        transaction"  as defined in Code  Section  1258(c),  up to the amount of
        interest  that would have  accrued on the Regular  Securityholder's  net
        investment  in the  conversion  transaction  at 120% of the  appropriate
        applicable  federal rate in effect at the time the taxpayer entered into
        the transaction minus any amount  previously  treated as ordinary income
        for any  prior  disposition  of  property  that was held as part of that
        transaction;

                (2)     in the case of a non-corporate  taxpayer,  to the extent
        that the taxpayer has made an election  under Code Section  163(d)(4) to
        have net capital  gains taxed as  investment  income at ordinary  income
        rates; or

                (3)     to the extent  that the gain does not exceed the excess,
        if any, of (a) the amount that would have been  includible  in the gross
        income of the holder if its yield on that Regular  Security were 110% of
        the  applicable  federal rate as of the date of  purchase,  over (b) the
        amount of income  actually  includible in the gross income of the holder
        for that Regular Security (the "110% yield rule").

        In addition, gain or loss recognized from the sale of a Regular Security
by some banks or thrift  institutions will be treated as ordinary income or loss
pursuant  to Code  Section  582(c).  Long-term  capital  gains  of  noncorporate
taxpayers generally are subject to a lower maximum tax rate than ordinary income
of those  taxpayers for property held for more than one year,  with further rate
reductions  for property held for more than five years.  Currently,  the maximum
tax rate for  corporations  is the same for both  ordinary  income  and  capital
gains.

        TAXATION OF OWNERS OF RESIDUAL SECURITIES

(1)     Taxation of REMIC Income

        Generally, the "daily portions" of REMIC taxable income or net loss will
be  includible as ordinary  income or loss in  determining  the federal  taxable
income of holders of Residual

                                      112



Securities ("Residual  Holders"),  and will not be taxed separately to the REMIC
Pool.  The daily  portions  of REMIC  taxable  income or net loss of a  Residual
Holder are  determined by allocating the REMIC Pool's taxable income or net loss
for each calendar  quarter ratably to each day in that quarter and by allocating
that daily portion among the Residual  Holders in proportion to their respective
holdings of Residual  Securities  in the REMIC Pool on that day.  REMIC  taxable
income is generally  determined  in the same manner as the taxable  income of an
individual using the accrual method of accounting, except that

                (1)     the limitations on deductibility of investment  interest
        expense and expenses for the production of income do not apply;

                (2)     all bad loans will be  deductible as business bad debts;
        and

                (3)     the  limitation  on the  deductibility  of interest  and
        expenses related to tax-exempt income will apply.

The REMIC Pool's gross income includes interest,  original issue discount income
and  market  discount  income,  if  any,  on  the  mortgage  loans,  reduced  by
amortization of any premium on the mortgage loans, plus income from amortization
of issue premium, if any, on the Regular Securities, plus income on reinvestment
of cash flows and reserve assets,  plus any cancellation of indebtedness  income
upon allocation of realized losses to the Regular Securities or as a result of a
Certificateholder,   particularly  an  interest  only  Regular   Security,   not
recovering  its  adjusted  issue  price.  The REMIC  Pool's  deductions  include
interest  and  original  issue  discount  expense  on  the  Regular  Securities,
servicing fees on the mortgage loans, other administrative expenses of the REMIC
Pool and realized  losses on the mortgage loans.  The requirement  that Residual
Holders  report their pro rata share of taxable  income or net loss of the REMIC
Pool will continue until there are no Notes or Certificates,  as applicable,  of
any class of the related series outstanding.

        The taxable income  recognized by a Residual  Holder in any taxable year
will be affected by, among other factors, the relationship between the timing of
recognition of interest,  original issue discount or market  discount  income or
amortization  of premium for the mortgage loans, on the one hand, and the timing
of deductions for interest  (including  original issue  discount) or income from
amortization of issue premium on the Regular  Securities,  on the other hand. If
an interest in the  mortgage  loans is acquired by the REMIC Pool at a discount,
and one or more of these mortgage  loans is prepaid,  the prepayment may be used
in whole or in part to make  distributions  in  reduction  of  principal  on the
Regular Securities, and the discount on the mortgage loans that is includible in
income may exceed the original issue discount deductions allowed with respect to
the Regular Securities.  When there is more than one Class of Regular Securities
that  distribute  principal   sequentially,   this  mismatching  of  income  and
deductions is particularly likely to occur in the early years following issuance
of the Regular Securities when distributions in reduction of principal are being
made in respect of earlier  Classes  of Regular  Securities  to the extent  that
those  Classes  are not  issued  with  substantial  discount  or are issued at a
premium.  If taxable income  attributable  to that  mismatching is realized,  in
general,  losses would be allowed in later years as  distributions  on the later
maturing Classes of Regular Securities are made.

        Taxable  income may also be greater in earlier years than in later years
as a  result  of the fact  that  interest  expense  deductions,  expressed  as a
percentage  of the  outstanding  principal  amount  of that  series  of  Regular
Securities,  may increase over time as  distributions  in reduction of principal
are made on the lower yielding Classes of Regular  Securities,  whereas,  to the
extent the REMIC Pool consists of fixed rate mortgage loans, interest income for
any particular  mortgage loan will remain  constant over time as a percentage of
the outstanding  principal amount of that loan.  Consequently,  Residual Holders
must have sufficient  other sources of cash to pay any federal,  state, or local
income taxes due as a result of that mismatching or unrelated deductions against
which to offset that income,  subject to the  discussion of "excess  inclusions"
below under

                                      113



"--Limitations   on  Offset  or  Exemption  of  REMIC  Income."  The  timing  of
mismatching of income and deductions described in this paragraph, if present for
a series of Notes or Certificates, as applicable, may have a significant adverse
effect upon a Residual Holder's after-tax rate of return.

        A portion of the income of a Residual Holder may be treated  unfavorably
in three contexts:

                (1)     it may not be offset by  current or net  operating  loss
        deductions;

                (2)     it will be considered  unrelated business taxable income
        to tax-exempt entities; and

                (3)     it is ineligible  for any statutory or treaty  reduction
        in the 30%  withholding  tax otherwise  available to a foreign  Residual
        Holder.

See "--Limitations on Offset or Exemption of REMIC Income" below. In addition, a
Residual  Holder's  taxable  income  during  some  periods may exceed the income
reflected  by those  Residual  Holders  for those  periods  in  accordance  with
generally accepted  accounting  principles.  Investors are encouraged to consult
their own accountants concerning the accounting treatment of their investment in
Residual Securities.

(2)     Basis and Losses

        The  amount  of any net loss of the REMIC  Pool  that may be taken  into
account by the Residual  Holder is limited to the adjusted basis of the Residual
Security as of the close of the quarter (or time of  disposition of the Residual
Security if earlier),  determined  without  taking into account the net loss for
the quarter. The initial adjusted basis of a purchaser of a Residual Security is
the amount paid for that Residual Security. The adjusted basis will be increased
by the amount of taxable  income of the REMIC Pool  reportable  by the  Residual
Holder and will be decreased (but not below zero), first, by a cash distribution
from the  REMIC  Pool and,  second,  by the  amount  of loss of the  REMIC  Pool
reportable  by the Residual  Holder.  Any loss that is  disallowed on account of
this  limitation may be carried over  indefinitely  with respect to the Residual
Holder as to whom the loss was disallowed and may be used by the Residual Holder
only to offset any income generated by the same REMIC Pool, but is not available
to a subsequent Residual Holder.

        A Residual Holder will not be permitted to amortize directly the cost of
its  Residual  Security as an offset to its share of the  taxable  income of the
related REMIC Pool.  However,  if, in any year, cash distributions to a Residual
Holder  exceed  its  share  of the  REMIC's  taxable  income,  the  excess  will
constitute  a return  of  capital  to the  extent of the  holder's  basis in its
Residual  Security.  A return of  capital is not  treated as income for  federal
income tax purposes,  but will reduce the tax basis of the Residual  Holder (but
not below zero).  If a Residual  Security's  basis is reduced to zero,  any cash
distributions  with  respect to that  Residual  Security in any taxable  year in
excess of its share of the REMIC's income would be taxable to the holder as gain
on the sale or exchange of its interest in the REMIC.

        A Residual  Security may have a negative  value if the net present value
of anticipated  tax  liabilities  exceeds the present value of anticipated  cash
flows.  The REMIC  Regulations  appear to treat the issue price of the  residual
interest as zero rather than the negative amount for purposes of determining the
REMIC Pool's basis in its assets.  The preamble to the REMIC Regulations  states
that the Internal  Revenue Service may provide future guidance on the proper tax
treatment of payments  made by a transferor  of the residual  interest to induce
the transferee to acquire the interest,  and Residual  Holders are encouraged to
consult their own tax advisors in this regard.

        Further,  to the extent  that the initial  adjusted  basis of a Residual
Holder (other than an original holder) in the Residual  Security is greater than
the corresponding portion of the REMIC

                                      114



Pool's  basis in the  mortgage  loans,  the  Residual  Holder will not recover a
portion of the basis until  termination of the REMIC Pool unless future Treasury
regulations  provide for  periodic  adjustments  to the REMIC  income  otherwise
reportable by the holder.  The REMIC  Regulations  currently in effect do not so
provide.  See "--Treatment of Certain Items of REMIC Income and  Expense--Market
Discount"  below  regarding  the basis of  mortgage  loans to the REMIC Pool and
"--Sale or Exchange of a Residual  Security" below regarding  possible treatment
of a loss upon termination of the REMIC Pool as a capital loss.

(3)     Treatment of Certain Items of REMIC Income and Expense

        Although it is  anticipated  that the trustee will compute  REMIC income
and  expense  in  accordance  with  the  Code and  applicable  regulations,  the
authorities  regarding the determination of specific items of income and expense
are subject to differing interpretations.  The depositor makes no representation
as to the specific method that will be used for reporting income with respect to
the  mortgage  loans and  expenses  for the Regular  Securities,  and  different
methods could result in different  timing or reporting of taxable  income or net
loss to Residual Holders or differences in capital gain versus ordinary income.

        ORIGINAL  ISSUE  DISCOUNT  AND  PREMIUM.  Generally,  the  REMIC  Pool's
deductions for original issue discount and income from  amortization  of premium
will be  determined  in the same manner as  original  issue  discount  income on
Regular  Securities as described  above under  "--Taxation  of Owners of Regular
Securities--Original  Issue Discount" and "--Variable Rate Regular  Securities,"
without  regard to the de minimis rule  described  therein,  and  "--Amortizable
Premium."

        MARKET  DISCOUNT.  The REMIC Pool will have  market  discount  income in
respect of mortgage  loans if, in general,  the basis of the REMIC Pool in those
mortgage loans is exceeded by their unpaid principal balances.  The REMIC Pool's
basis in those mortgage loans is generally the fair market value of the mortgage
loans  immediately  after the transfer of the mortgage  loans to the REMIC Pool.
The REMIC Regulations  provide that the basis is equal to the total of the issue
prices of all  regular and  residual  interests  in the REMIC  Pool.  The market
discount  must be  recognized  currently  as an item of  ordinary  income  as it
accrues, rather than being included in income upon the sale of mortgage loans or
as principal on the mortgage loans is paid.  Market  discount  income  generally
should  accrue in the manner  described  above  under  "--Taxation  of Owners of
Regular Securities--Market Discount."

        PREMIUM. Generally, if the basis of the REMIC Pool in the mortgage loans
exceeds the unpaid principal balances of the mortgage loans, the REMIC Pool will
be considered to have acquired  those  mortgage  loans at a premium equal to the
amount of that excess. As stated above, the REMIC Pool's basis in mortgage loans
is generally  the fair market  value of the  mortgage  loans and is based on the
total of the issue  prices of the regular and  residual  interests  in the REMIC
Pool immediately  after the transfer of the mortgage loans to the REMIC Pool. In
a manner  analogous  to the  discussion  above  under  "--Taxation  of Owners of
Regular Securities--Amortizable Premium," a person that holds a mortgage loan as
a capital  asset under Code  Section  1221 may elect  under Code  Section 171 to
amortize  premium on mortgage loans  originated  after September 27, 1985, under
the constant yield method. Amortizable bond premium will be treated as an offset
to interest  income on the mortgage loans,  rather than as a separate  deduction
item.  Because  substantially  all of the  borrowers on the  mortgage  loans are
expected to be  individuals,  Code Section 171 will not be available for premium
on mortgage loans originated on or before September 27, 1985.  Premium for those
mortgage  loans  may  be  deductible  in  accordance  with a  reasonable  method
regularly employed by the holder of those mortgage loans. The allocation of that
premium pro rata among  principal  payments  should be  considered  a reasonable
method;  however, the Internal Revenue Service may argue that the premium should
be allocated in a different  manner,  such as allocating the premium entirely to
the final payment of principal.

                                      115



(4)     Limitations on Offset or Exemption of REMIC Income

        A portion (or all) of the REMIC taxable income includible in determining
the federal income tax liability of a Residual Holder will be subject to special
treatment.  That portion, referred to as the "excess inclusion," is equal to the
excess of REMIC taxable income for the calendar quarter  allocable to a Residual
Security over the daily  accruals for that  quarterly  period of (1) 120% of the
long-term  applicable  federal  rate that  would have  applied  to the  Residual
Security  (if it were a debt  instrument)  on the Startup Day under Code Section
1274(d),  multiplied by (2) the adjusted issue price of the Residual Security at
the beginning of the quarterly  period.  For this  purpose,  the adjusted  issue
price of a Residual Security at the beginning of a quarter is the issue price of
the Residual  Security,  plus the amount of those daily accruals of REMIC income
described  in  this  paragraph  for  all  prior   quarters,   decreased  by  any
distributions made with respect to the Residual Security before the beginning of
that quarterly period.

        The portion of a Residual  Holder's REMIC taxable  income  consisting of
the excess inclusions generally may not be offset by other deductions, including
net operating loss carryforwards,  on the Residual Holder's return. However, net
operating  loss  carryovers are  determined  without regard to excess  inclusion
income. Further, if the Residual Holder is an organization subject to the tax on
unrelated  business  income  imposed by Code Section 511, the Residual  Holder's
excess  inclusions will be treated as unrelated  business  taxable income of the
Residual  Holder for purposes of Code Section  511. In addition,  REMIC  taxable
income is subject to 30%  withholding  tax for persons who are not U.S.  Persons
(as defined  below  under  "--Tax-Related  Restrictions  on Transfer of Residual
Securities--Foreign  Investors"), and the portion thereof attributable to excess
inclusions is not eligible for any reduction in the rate of withholding  tax (by
treaty or otherwise).  See  "--Taxation of Certain  Foreign  Investors--Residual
Securities"  below.  Finally,  if a real estate  investment trust or a regulated
investment company owns a Residual Security, a portion (allocated under Treasury
regulations  yet to be issued) of dividends  paid by the real estate  investment
trust or  regulated  investment  company  could not be  offset by net  operating
losses of its shareholders,  would constitute  unrelated business taxable income
for  tax-exempt   shareholders,   and  would  be  ineligible  for  reduction  of
withholding to persons who are not U.S. Persons.

        Provisions  governing the relationship between excess inclusions and the
alternative  minimum tax provide that (i) alternative minimum taxable income for
a Residual  Holder is determined  without regard to the special rule,  discussed
above,  that  taxable  income  cannot be less  than  excess  inclusions,  (ii) a
Residual Holder's  alternative  minimum taxable income for a taxable year cannot
be less than the  excess  inclusions  for the year,  and (iii) the amount of any
alternative  minimum tax net operating loss  deduction must be computed  without
regard to any excess inclusions.

        The Internal  Revenue  Service has authority to  promulgate  regulations
providing  that  if the  aggregate  value  of  the  Residual  Securities  is not
considered to be "significant," then the entire share of REMIC taxable income of
a Residual Holder may be treated as excess  inclusions  subject to the foregoing
limitations. This authority has not been exercised to date.

(5)     Tax-Related Restrictions on Transfer of Residual Securities

        DISQUALIFIED  ORGANIZATIONS.  If any legal or  beneficial  interest in a
Residual  Security is  transferred to a  Disqualified  Organization  (as defined
below),  a tax would be  imposed  in an amount  equal to the  product of (1) the
present  value of the total  anticipated  excess  inclusions  for that  Residual
Security for periods  after the transfer  and (2) the highest  marginal  federal
income tax rate applicable to corporations.  The REMIC Regulations  provide that
the anticipated  excess inclusions are based on actual prepayment  experience to
the  date  of the  transfer  and  projected  payments  based  on the  Prepayment
Assumption. The present value rate equals the applicable

                                      116



federal  rate under Code  Section  1274(d) as of the date of the  transfer for a
term  ending  with the last  calendar  quarter in which  excess  inclusions  are
expected to accrue.  That rate is applied to the anticipated  excess  inclusions
from the end of the remaining  calendar quarters in which they arise to the date
of the transfer.  That tax generally  would be imposed on the  transferor of the
Residual Security, except that where the transfer is through an agent (including
a broker, nominee, or other middleman) for a Disqualified Organization,  the tax
would  instead  be imposed on the agent.  However,  a  transferor  of a Residual
Security  would  in no  event  be  liable  for  the tax  for a  transfer  if the
transferee  furnished to the transferor an affidavit stating that the transferee
is not a  Disqualified  Organization  and, as of the time of the  transfer,  the
transferor does not have actual knowledge that the affidavit is false. Under the
REMIC Regulations,  an affidavit will be sufficient if the transferee  furnishes
(A) a social  security  number,  and states under  penalties of perjury that the
social  security  number is that of the  transferee,  or (B) a  statement  under
penalties of perjury that it is not a disqualified organization.

        "Disqualified   Organization"   means  the  United  States,   any  state
(including  the  District of Columbia) or  political  subdivision  thereof,  any
foreign   government,   any   international   organization,    any   agency   or
instrumentality  of any of the  foregoing  (provided,  that  the  term  does not
include an  instrumentality  if all of its  activities  are  subject to tax and,
except for the Federal Home Loan Mortgage  Corporation,  a majority of its board
of  directors  in not  selected by any  governmental  entity),  any  cooperative
organization  furnishing  electric  energy or  providing  telephone  service  to
persons in rural  areas as  described  in Code  Section  1381(a)(2)(C),  and any
organization (other than a farmers'  cooperative  described in Code Section 521)
that is exempt from taxation under the Code unless the  organization  is subject
to the tax on unrelated business income imposed by Code Section 511.

        In addition,  if a  "Pass-Through  Entity" (as defined below) has excess
inclusion  income  for  a  Residual   Security  during  a  taxable  year  and  a
Disqualified  Organization  is the record  holder of an equity  interest in that
entity,  then a tax is  imposed on the  entity  equal to the  product of (1) the
amount  of  excess  inclusions  that  are  allocable  to  the  interest  in  the
Pass-Through  Entity during the period that interest is held by the Disqualified
Organization,  and (2) the highest marginal  federal  corporate income tax rate.
That tax would be deductible from the ordinary gross income of the  Pass-Through
Entity for the taxable year. The Pass-Through Entity would not be liable for the
tax if (1) it has received an affidavit  from the record holder  stating,  under
penalties of perjury, that it is not a Disqualified  Organization,  or providing
the holder's  taxpayer  identification  number and stating,  under  penalties of
perjury,  that the social security  number is that of the record owner,  and (2)
during the period that person is the record holder of the Residual Security, the
Pass-Through Entity does not have actual knowledge that the affidavit is false.

        "Pass-Through  Entity"  means any  regulated  investment  company,  real
estate investment trust, common trust fund, partnership, trust or estate and any
organization  treated as a cooperative under Code Section 1381. Except as may be
provided  in  Treasury  regulations,   any  person  holding  an  interest  in  a
Pass-Through  Entity  as a  nominee  for  another  will,  with  respect  to that
interest, be treated as a Pass-Through Entity.

        If an  "electing  large  partnership"  holds a  Residual  Security,  all
interests in the electing large  partnership are treated as held by Disqualified
Organizations  for  purposes of the tax imposed  upon a  Pass-Through  Entity by
Section 860E(e) of the Code. The exception to this tax, otherwise available to a
Pass-Through Entity that is furnished particular affidavits by record holders of
interests in the entity and that does not know those  affidavits  are false,  is
not available to an electing large partnership.

        The pooling and  servicing  agreement  for a series will provide that no
legal or  beneficial  interest  in a Residual  Security  may be  transferred  or
registered  unless (1) the proposed  transferee  furnished to the transferor and
the trustee an affidavit providing its taxpayer identification number

                                      117



and stating that the transferee is the beneficial owner of the Residual Security
and is not a  Disqualified  Organization  and is  not  purchasing  the  Residual
Security on behalf of a Disqualified Organization (i.e., as a broker, nominee or
middleman) and (2) the transferor provides a statement in writing to the trustee
that it has no actual  knowledge  that the  affidavit  is false.  Moreover,  the
pooling and  servicing  agreement  will provide that any  attempted or purported
transfer in violation of these transfer  restrictions  will be null and void and
will vest no rights in any purported  transferee.  Each Residual  Security for a
series will bear a legend referring to those restrictions on transfer,  and each
Residual  Holder will be deemed to have  agreed,  as a condition of ownership of
the Residual  Security,  to any amendments to the related  pooling and servicing
agreement  required  under  the  Code  or  applicable  Treasury  regulations  to
effectuate  the  foregoing  restrictions.  Information  necessary  to compute an
applicable  excise tax must be furnished to the Internal  Revenue Service and to
the  requesting  party  within  60 days of the  request,  and the  Seller or the
trustee may charge a fee for computing and providing that information.

        NONECONOMIC   RESIDUAL  INTERESTS.   The  REMIC  Regulations   disregard
transfers of Residual Securities under certain circumstances,  in which case the
transferor would continue to be treated as the owner of the Residual  Securities
and thus would continue to be subject to tax on its allocable portion of the net
income  of the  REMIC  Pool.  Under  the  REMIC  Regulations,  a  transfer  of a
"noneconomic  residual  interest" (as defined below) to a Residual Holder (other
than a  Residual  Holder  who  is  not a U.S.  Person  as  defined  below  under
"--Foreign  Investors")  is  disregarded to all federal income tax purposes if a
significant purpose of the transfer is to impede the assessment or collection of
tax. A residual  interest  in a REMIC  (including  a  residual  interest  with a
positive value at issuance) is a "noneconomic  residual interest" unless, at the
time of the transfer, (1) the present value of the expected future distributions
on the residual interest at least equals the product of the present value of the
anticipated  excess  inclusions  and the  highest  corporate  income tax rate in
effect  for the  year in  which  the  transfer  occurs,  and (2) the  transferor
reasonably expects that the transferee will receive distributions from the REMIC
at or after the time at which taxes accrue on the anticipated  excess inclusions
in an amount  sufficient to satisfy the accrued taxes on each excess  inclusion.
The anticipated  excess  inclusions and the present value rate are determined in
the same  manner as set forth above under  "--Disqualified  Organizations."  The
REMIC Regulations explain that a significant purpose to impede the assessment or
collection of tax exists if the transferor,  at the time of the transfer, either
knew or should have known that the  transferee  would be  unwilling or unable to
pay taxes due on its share of the taxable  income of the REMIC. A safe harbor is
provided  if (1)  the  transferor  conducted,  at the  time of the  transfer,  a
reasonable  investigation of the financial condition of the transferee and found
that the transferee  historically  had paid its debts as they came due and found
no significant  evidence to indicate that the  transferee  would not continue to
pay its debts as they came due in the future,  (2) the transferee  represents to
the  transferor  that it  understands  that,  as the holder of the  non-economic
residual  interest,  the transferee may incur  liabilities in excess of any cash
flows  generated by the interest  and that the  transferee  intends to pay taxes
associated with holding the residual interest as they become due, and (3) either
the formula test or the asset test (each as described below) is satisfied.

        The formula test is satisfied  if the present  value of the  anticipated
tax liabilities  associated  with holding the Residual  Security does not exceed
the sum of the present values of (1) any  consideration  given to the transferee
to the acquire the Residual Security,  (2) the expected future  distributions on
the Residual  Security,  and (3) the  anticipated  tax savings  associated  with
holding the Residual  Security as the REMIC  generates  losses.  For purposes of
this  calculation,  the present values generally are calculated using a discount
rate equal to the applicable  federal rate, and the transferee is assumed to pay
tax at the highest corporate rate of tax.

        The asset test is satisfied if

        1.  at the time of the  transfer of the  Residual  Security,  and at the
            close of each of the  transferee's  two fiscal years  preceding  the
            year of transfer, the transferee's gross


                                      118



            assets for financial  reporting purposes exceed $100 million and its
            net assets for financial reporting purposes exceed $10 million,

        2.  the  transferee is a taxable  domestic C  corporation,  other than a
            RIC, REIT, REMIC or a cooperative  corporation to which subchapter T
            of  Chapter  1 of  subtitle  A of the  Code  applies  (an  "Eligible
            Corporation"),  that makes a written  agreement  that any subsequent
            transfer  of the  Residual  Security  will  be to  another  Eligible
            Corporation  in  a  transaction   that  satisfies  the  safe  harbor
            described above, and the transferor does not know, or have reason to
            know, that the transferee will not honor such agreement, and

        3.  the facts and circumstances known to the transferor on or before the
            date  of  transfer  do  not  reasonably   indicate  that  the  taxes
            associated with the Residual Security will not be paid.

For purposes of requirement (1), the gross and net assets of a transferee do not
include any obligations of a person related to the transferee or any other asset
if a  principal  purpose  for  holding or  acquiring  the asset is to permit the
transferee  to satisfy the asset  test.  Further,  the formula  test will not be
treated as satisfied in the case of any transfer or  assignment  of the Residual
Security to a foreign branch of an Eligible Corporation or any other arrangement
by which the  Residual  Security is at any time  subject to net tax by a foreign
country or possession of the United States.

        Foreign Investors.  The REMIC Regulations provide that the transfer of a
Residual Security that has "tax avoidance  potential" to a "foreign person" will
be disregarded  for all federal tax purposes.  This rule applies to a transferee
who is not a "U.S. Person" (as defined below), unless the transferee's income is
effectively  connected with the conduct of a trade or business within the United
States. A Residual Security is deemed to have tax avoidance potential unless, at
the time of the transfer,  the transferor reasonably expects that (1) the future
distributions  on  the  Residual  Security  will  equal  at  least  30%  of  the
anticipated  excess inclusions after the transfer,  and (2) such amounts will be
distributed  at or after  the time at which the  excess  inclusions  accrue  and
before the end of the calendar  taxable  year  following  the  calendar  year of
accrual.  A safe harbor in the REMIC  Regulations  provides that the  reasonable
expectation  requirement will be satisfied if the above test would be met at all
assumed  prepayment  rates for the mortgage loans from 50 percent to 200 percent
of the  Prepayment  Assumption.  If the non-U.S.  Person  transfers the Residual
Security back to a U.S. Person, the transfer will be disregarded and the foreign
transferor will continue to be treated as the owner unless arrangements are made
so that the  transfer  does not have the effect of allowing  the  transferor  to
avoid tax on accrued excess inclusions.

        The prospectus  supplement  relating to the Certificates of a series may
provide that a Residual  Security may not be purchased by or  transferred to any
person  that  is not a  U.S.  Person  or  may  describe  the  circumstances  and
restrictions  pursuant to which the transfer may be made. The term "U.S. Person"
means a citizen or resident of the United  States,  a corporation or partnership
(or other entity  properly  treated as a  partnership  or as a  corporation  for
federal  income tax  purposes)  created or organized in or under the laws of the
United  States or of any state  (including,  for this  purpose,  the District of
Columbia),  an estate that is subject to U.S.  federal  income tax regardless of
the source of its income, or a trust if a court within the United States is able
to exercise primary  supervision over the administration of the trust and one or
more U.S. Persons have the authority to control all substantial decisions of the
trust (or, to the extent provided in applicable Treasury regulations,  trusts in
existence  on August 20,  1996,  which are  eligible to elect and do elect to be
treated as U.S.  Persons).  In addition,  a REMIC  Residual  Interest held by an
entity treated as a partnership  for federal tax purposes may be treated as held
by its equity owners.

                                      119



(6)     Sale or Exchange of a Residual Security

        Upon the sale or exchange of a Residual  Security,  the Residual  Holder
will recognize gain or loss equal to the excess,  if any, of the amount realized
over the  adjusted  basis (as  described  above under  "--Taxation  of Owners of
Residual  Securities--Basis  and Losses") of the Residual Holder in the Residual
Security at the time of the sale or exchange.

        Further,  as  described  above under  "--Taxation  of Owners of Residual
Securities--Basis  and  Losses",  if a Residual  Security's  basis is reduced to
zero,  any cash  distributions  with  respect to that  Residual  Security in any
taxable year in excess of its share of the REMIC's income for that year would be
taxable to the holder as gain on the sale or  exchange  of its  interest  in the
REMIC. If a Residual Holder has an adjusted basis in its Residual  Security when
its interest in the REMIC Pool terminates, then it will recognize a loss at that
time in an amount equal to the remaining adjusted basis.

        Any gain on the sale of a Residual  Security will be treated as ordinary
income (1) if a Residual Security is held as part of a "conversion  transaction"
as defined in Code Section 1258(c), up to the amount of interest that would have
accrued on the Residual Holder's net investment in the conversion transaction at
120% of the  appropriate  applicable  federal  rate in  effect  at the  time the
taxpayer  entered into the transaction  minus any amount  previously  treated as
ordinary income for any prior disposition of property that was held as a part of
that transaction or (2) in the case of a non-corporate  taxpayer,  to the extent
that the taxpayer has made an election under Code Section  163(d)(4) to have net
capital gains taxed as investment  income at ordinary income rates. In addition,
gain or loss  recognized  from the sale of a Residual  Security by some banks or
thrift  institutions will be treated as ordinary income or loss pursuant to Code
Section 582(c).

        Except as provided in Treasury  regulations  yet to be issued,  the wash
sale  rules  of Code  Section  1091  will  apply  to  dispositions  of  Residual
Securities  where  the  seller  of the  Residual  Security,  during  the  period
beginning six months before the sale or disposition of the Residual Security and
ending six months  after the sale or  disposition,  acquires (or enters into any
other  transaction  that results in the  application  of Code Section  1091) any
residual  interest  in any REMIC or any  interest in a "taxable  mortgage  pool"
(such as a non-REMIC owner trust) that is economically  comparable to a Residual
Security.

(7)     Mark to Market Regulations

        Treasury  regulations  provide that a Residual  Security  acquired on or
after January 4, 1995 is not treated as a security and thus may not be marked to
market pursuant to Section 475 of the Code.

(8)     Inducement Fees

        Regulations have been adopted regarding the federal income tax treatment
of "inducement  fees" received by  transferees  of  non-economic  REMIC residual
interests. The regulations (i) provide tax accounting rules for the treatment of
such fees as income over an appropriate  period and (ii) specify that inducement
fees  constitute  income  from  sources  within the United  States.  Prospective
purchasers  of the Residual  Certificates  are  encouraged  to consult their tax
advisors  regarding the effect of these  regulations and the tax consequences of
receiving any inducement fee.

                                      120



        TAXES THAT MAY BE IMPOSED ON THE REMIC POOL

(1)     Prohibited Transactions

        Income  from   transactions  by  the  REMIC  Pool,   called   prohibited
transactions,  will not be part of the  calculation of income or loss includible
in the federal income tax returns of Residual Holders,  but rather will be taxed
directly  to the REMIC Pool at a 100% rate.  Prohibited  transactions  generally
include:

                (1)     the disposition of a qualified mortgages other than for:

                        (a)     substitution   for  a  defective   (including  a
                        defaulted)  obligation  within two years of the  Startup
                        Day  (or  repurchase  in  lieu  of   substitution  of  a
                        defective  (including  a  defaulted)  obligation  at any
                        time) or for any qualified  mortgage within three months
                        of the Startup Day;

                        (b)     foreclosure,  default,  or imminent default of a
                        qualified mortgage;

                        (c)     bankruptcy or insolvency of the REMIC Pool; or

                        (d)     a qualified (complete) liquidation;

                (2)     the receipt of income from assets that are not qualified
        mortgages or investments that the REMIC Pool is permitted to hold;

                (3)     the receipt of compensation for services; or

                (4)     the  receipt  of gain  from  disposition  of  cash  flow
        investments other than pursuant to a qualified liquidation.

        Notwithstanding (1) and (4) above, it is not a prohibited transaction to
sell a  qualified  mortgage  or cash  flow  investment  held by a REMIC  Pool to
prevent a default on Regular  Securities  as a result of a default on  qualified
mortgages or to facilitate a clean-up call of a class of REMIC regular  interest
to save  administrative  costs when no more than a small percentage of the Notes
or Certificates,  as applicable, is outstanding.  The REMIC Regulations indicate
that the  modification  of a mortgage  loan  generally  will not be treated as a
disposition  for this  purpose if it is  occasioned  by a default or  reasonably
foreseeable  default,  an  assumption  of the  mortgage  loan,  the  waiver of a
due-on-sale or due-on-encumbrance  clause, or the conversion of an interest rate
by a borrower  pursuant to the terms of a convertible  adjustable  rate mortgage
loan.

(2)     Contributions to the REMIC Pool After the Startup Day

        In  general,  the REMIC  Pool will be subject to a tax at a 100% rate on
the value of any property  contributed  to the REMIC Pool after the Startup Day.
Exceptions are provided for cash contributions to the REMIC Pool

                (1)     during the three months following the Startup Day,

                (2)     made to a qualified reserve fund by a Residual Holder,

                (3)     in the nature of a guarantee,

                (4)     made to facilitate a qualified  liquidation  or clean-up
        call, and

                                      121



                (5)     as otherwise permitted in Treasury regulations yet to be
        issued.

It is not  anticipated  that there will be any  contributions  to the REMIC Pool
after the Startup Day that do not qualify for an exception from the 100% penalty
tax.

(3)     Net Income from Foreclosure Property

        The REMIC  Pool will be subject  of  federal  income tax at the  highest
corporate  rate  on  "net  income  from  foreclosure  property,"  determined  by
reference to the rules applicable to real estate investment  trusts.  Generally,
property  acquired by  foreclosure  or by deed in lieu of  foreclosure  would be
treated as  "foreclosure  property"  until the close of the third  calendar year
after  the year in which  the  REMIC  Pool  acquired  that  property,  unless an
extension  of  up  to  three  additional  years  is  granted.  Net  income  from
foreclosure  property  generally  means  gain  from  the  sale of a  foreclosure
property that is inventory  property and gross income from foreclosure  property
other than income that would be qualifying rents and other qualifying income for
a real estate  investment  trust. It is not anticipated that the REMIC Pool will
have any taxable net income from foreclosure property.

(4)     Liquidation of the REMIC Pool

        If a REMIC  Pool  adopts  a plan of  complete  liquidation,  within  the
meaning  of  Code  Section  860F(a)(4)(A)(i),   which  may  be  accomplished  by
designating  in the REMIC Pool's final tax return a date on which that  adoption
is deemed to occur,  and sells all of its  assets  (other  than  cash)  within a
90-day period  beginning on that date, the REMIC Pool will not be subject to the
prohibited transaction rules on the sale of its assets,  provided that the REMIC
Pool credits or  distributes  in  liquidation  all of the sale proceeds plus its
cash  (other  than  amounts  retained  to meet  claims)  to  holders  of Regular
Securities and Residual Holders within the 90-day period.

(5)     Administrative Matters

        The REMIC Pool will be required to maintain its books on a calendar year
basis and to file federal  income tax returns for federal income tax purposes in
a manner  similar to a  partnership.  The form for the income tax return is Form
1066,  U.S.  Real Estate  Mortgage  Investment  Conduit  Income Tax Return.  The
trustee will be required to sign the REMIC Pool's returns.  Treasury regulations
provide  that,  except  where  there is a single  Residual  Holder for an entire
taxable  year,   the  REMIC  Pool  will  be  subject  to  the   procedural   and
administrative  rules of the Code  applicable  to  partnerships,  including  the
determination by the Internal Revenue Service of any adjustments to, among other
things,  items of REMIC income,  gain, loss,  deduction,  or credit in a unified
administrative  proceeding. The master servicer will be obligated to act as "tax
matters person," as defined in applicable  Treasury  regulations,  for the REMIC
Pool as agent of the Residual Holders holding the largest percentage interest in
the Residual  Securities.  If the Code or applicable Treasury regulations do not
permit the master servicer to act as tax matters person in its capacity as agent
of the  Residual  Holder,  the  Residual  Holder or any other  person  specified
pursuant to Treasury  regulations will be required to act as tax matters person.
The tax matters person generally has responsibility for overseeing and providing
notice to the other Residual Holders of administrative and judicial  proceedings
regarding the REMIC Pool's tax affairs,  although  other holders of the Residual
Securities of the same series would be able to participate in those  proceedings
in appropriate circumstances.

(6)     Limitations on Deduction of Certain Expenses

        An investor who is an  individual,  estate,  or trust will be subject to
limitation  with respect to some itemized  deductions  described in Code Section
67, to the extent that those itemized deductions,  in total, do not exceed 2% of
the investor's adjusted gross income. In the case of a

                                      122



partnership  that  has 100 or more  partners  and  elects  to be  treated  as an
"electing large partnership," 70% of that partnership's  miscellaneous  itemized
deductions will be disallowed,  although the remaining deductions will generally
be allowed at the partnership level and will not be subject to the 2% floor that
would otherwise be applicable to individual partners. In addition,  Code Section
68, provides that itemized deductions  otherwise allowable for a taxable year of
an individual  taxpayer will be reduced by the lesser or (1) 3% of the excess of
adjusted  gross  income in  excess of a  specified  threshold  amount  (which is
adjusted  annually  for  inflation),  or  (2)  80%  of the  amount  of  itemized
deductions  otherwise  allowable for that year. The reduction under Code Section
68 is itself reduced by one-third for taxable years  beginning in 2006 and 2007,
two-thirds  for taxable years  beginning in 2008 and 2009, and fully reduced for
taxable years beginning in 2010 with no reduction  thereafter.  In the case of a
REMIC Pool, those  deductions may include  deductions under Code Section 212 for
the  Servicing Fee and all  administrative  and other  expenses  relating to the
REMIC Pool,  or any similar  expenses  allocated to the REMIC Pool for a regular
interest it holds in another REMIC.  Those  investors who hold REMIC  Securities
either directly or indirectly through  pass-through  entities may have their pro
rata share of those expenses  allocated to them as additional gross income,  but
may be subject to that limitation on deductions. In addition, those expenses are
not deductible at all for purposes of computing the alternative minimum tax, and
may cause those investors to be subject to significant additional tax liability.
Temporary  Treasury  regulations  provide that the  additional  gross income and
corresponding  amount of expenses  generally are to be allocated entirely to the
holders  of  Residual  Securities  in the case of a REMIC  Pool  that  would not
qualify as a fixed  investment  trust in the absence of a REMIC election.  For a
REMIC Pool that would be classified  as an investment  trust in the absence of a
REMIC  election or that is  substantially  similar to an investment  trust,  any
holder  of  a  Regular  Security  that  is  an  individual,  trust,  estate,  or
pass-through  entity also will be allocated its pro rata share of those expenses
and a  corresponding  amount of income and will be subject to the limitations or
deductions  imposed  by  Code  Sections  67 and  68,  as  described  above.  The
prospectus  supplement will indicate if all those expenses will not be allocable
to the Residual Securities.

        TAXATION OF CERTAIN FOREIGN INVESTORS

(1)     Regular Securities

        Interest,  including  original issue discount,  distributable to Regular
Securityholders  who are non-resident  aliens,  foreign  corporations,  or other
Non-U.S.  Persons (as defined  below),  generally will be considered  "portfolio
interest"  and,  therefore,  generally  will not be subject to 30% United States
withholding  tax,  provided that (1) the interest is not  effectively  connected
with  the  conduct  of  a  trade  or  business  in  the  United  States  of  the
securityholder, (2) the Non-U.S. Person is not a "10-percent shareholder" within
the meaning of Code Section  871(h)(3)(B)  or a controlled  foreign  corporation
described in Code Section 881(c)(3)(C) and (3) that Non-U.S.  Person complies to
the extent necessary with certain  certification  requirements,  which generally
relate to the identity of the beneficial  owner and the status of the beneficial
owner as a person that is a Non-U.S.  person.  Each  Regular  Securityholder  is
encouraged  to consult its tax  advisors  regarding  the tax  documentation  and
certifications  that must be provided to secure the exemption from United States
withholding taxes.

        Any capital gain realized on the sale,  redemption,  retirement or other
taxable disposition of a Regular Security by a Non-U.S. Person generally will be
exempt from United States federal income and withholding tax,  provided that (i)
such gain is not  effectively  connected with the conduct of a trade or business
in the  United  States  by the  Non-U.S.  Person  and  (ii)  in the  case  of an
individual  Non-U.S.  Person,  the Non-U.S.  Person is not present in the United
States for 183 days or more in the taxable year.

                                      123



        If the interest on the Regular  Security is  effectively  connected with
the conduct of a trade or  business  within the United  States by that  Non-U.S.
Person, the Non-U.S. Person, although exempt from the withholding tax previously
discussed if the holder provides an appropriate statement establishing that such
income is so  effectively  connected,  will be subject to United States  federal
income tax at regular rates.  Investors who are Non-U.S.  Persons are encouraged
to consult  their own tax advisors  regarding the specific tax  consequences  to
them of owning a Regular Security.  The term "Non-U.S.  Person" means any person
who is not a U.S. Person.

(2)     Residual Securities

        The Conference  Committee  Report to the 1986 Act indicates that amounts
paid to Residual Holders who are Non-U.S. Persons generally should be treated as
interest  for  purposes  of  the  30%  (or  lower  treaty  rate)  United  States
withholding  tax.  Treasury  regulations  provide  that  amount  distributed  to
Residual Holders may qualify as "portfolio  interest," subject to the conditions
described  in "Regular  Securities"  above,  but only to the extent that (1) the
mortgage  loans were issued after July 18, 1984,  and (2) the issuing  entity or
segregated  pool of assets in the issuing  entity (as to which a separate  REMIC
election  will be made),  to which the Residual  Security  relates,  consists of
obligations  issued in "registered  form" within the meaning of Code Section 163
(f) (1). Generally, mortgage loans will not be, but regular interests in another
REMIC  Pool  will  be,  considered   obligations   issued  in  registered  form.
Furthermore, Residual Holders will not be entitled to any exemption from the 30%
withholding  tax (or lower  treaty  rate) to the extent of that portion of REMIC
taxable income that constitutes an "excess inclusion." See "--Taxation of Owners
of Residual  Securities--Limitations  on Offset or  Exemption  of REMIC  Income"
above.  If the amounts  paid to Residual  Holders who are  Non-U.S.  Persons are
effectively  connected with the conduct of a trade or business within the United
States by those  Non-U.S.  Persons,  although  exempt from the  withholding  tax
previously   discussed  if  the  holder   provides  an   appropriate   statement
establishing that such income is so effectively  connected,  the amounts paid to
those  Non-U.S.  Persons will be subject to United States  federal income tax at
regular  rates.  See   "--Tax-Related   Restrictions  on  Transfer  of  Residual
Securities--Foreign  Investors"  above  concerning  the  disregard  of transfers
having  "tax  avoidance  potential."  Investors  who are  Non-U.S.  Persons  are
encouraged  to  consult  their  own tax  advisors  regarding  the  specific  tax
consequences to them of owning Residual Securities.

(3)     Backup Withholding

        Distributions  made on the REMIC Securities,  and proceeds from the sale
of the REMIC  Securities  to or  through  certain  brokers,  may be subject to a
"backup"  withholding  tax under  Code  Section  3406 on  "reportable  payments"
(including  interest  distributions,  original issue  discount,  and, under some
circumstances,  principal  distributions)  if the  Holder  fails to comply  with
certain  identification  procedures,  unless the Holder is  otherwise  an exempt
recipient  under   applicable   provisions  of  the  Code,  and,  if  necessary,
demonstrates  such status.  Any amounts to be withheld from  distribution on the
REMIC Securities would be refunded by the Internal Revenue Service or allowed as
a credit against the Regular Holder's federal income tax liability.

GRANTOR TRUST FUNDS

        CHARACTERIZATION.  For each series of Grantor Trust Securities,  Federal
Tax Counsel  will  deliver its opinion  that the Grantor  Trust Fund will not be
classified as an association taxable as a corporation and that the Grantor Trust
Fund will be classified as a grantor trust under subpart E, Part I of subchapter
J of chapter 1 of  subtitle A of the Code.  In this case,  beneficial  owners of
Grantor  Trust  Securities  (referred to in this  Prospectus  as "Grantor  Trust
Securityholders") will be treated for federal income tax purposes as owners of a
portion of the Grantor Trust Fund's assets as described below.

                                      124



        TAXATION OF GRANTOR  TRUST  SECURITYHOLDERS.  Subject to the  discussion
below  under  "Stripped  Certificates"  and  "Subordinated  Certificates,"  each
Grantor  Trust  Securityholder  will  be  treated  as the  owner  of a pro  rata
undivided  interest in the assets of the Grantor  Trust Fund.  Accordingly,  and
subject to the discussion below of the  recharacterization of the servicing fee,
each Grantor Trust  Securityholder  must include in income its pro rata share of
the  interest  and other  income  from the  assets of the  Grantor  Trust  Fund,
including any interest,  original issue discount,  market  discount,  prepayment
fees, assumption fees, and late payment charges with respect to the assets, and,
subject to  limitations  discussed  below,  may deduct its pro rata share of the
fees and other  deductible  expenses paid by the Grantor Trust Fund, at the same
time and to the same  extent as these items would be included or deducted by the
Grantor Trust Securityholder if the Grantor Trust Securityholder held directly a
pro rata  interest in the assets of the Grantor Trust Fund and received and paid
directly the amounts  received and paid by the Grantor  Trust Fund.  Any amounts
received by a Grantor Trust  Securityholder  in lieu of amounts due with respect
to any asset of the Grantor  Trust Fund because of a default or  delinquency  in
payment  will be treated  for  federal  income tax  purposes  as having the same
character as the payments they replace.

        Each  Grantor  Trust  Securityholder  will be entitled to deduct its pro
rata  share of  servicing  fees,  prepayment  fees,  assumption  fees,  any loss
recognized upon an assumption and late payment charges retained by the servicer,
provided that these amounts are reasonable compensation for services rendered to
the Grantor Trust Fund.  Grantor  Trust  Securityholders  that are  individuals,
estates or trusts will be entitled to deduct their share of expenses only to the
extent these expenses plus all other  miscellaneous  itemized  deductions exceed
two percent of the Grantor Trust  Securityholder's  adjusted  gross income,  and
will be allowed no deduction for these expenses in determining their liabilities
for alternative minimum tax. In addition,  Section 68 of the Code, provides that
the amount of itemized  deductions  otherwise allowable for the taxable year for
an individual whose adjusted gross income exceeds a prescribed  threshold amount
will be reduced by the lesser of (1) 3% of the excess of adjusted  gross  income
over the specified threshold amount (adjusted annually for inflation) or (2) 80%
of the amount of itemized  deductions  otherwise  allowable  for the  applicable
taxable year. The reduction under Code Section 68 is itself reduced by one-third
for taxable  years  beginning  in 2006 and 2007,  two-thirds  for taxable  years
beginning in 2008 and 2009,  and fully  reduced for taxable  years  beginning in
2010 with no reduction thereafter.  In the case of a partnership that has 100 or
more partners and elects to be treated as an "electing large  partnership,"  70%
of the  partnership's  miscellaneous  itemized  deductions  will be  disallowed,
although the remaining  deductions  will generally be allowed at the partnership
level and will not be subject to the 2% floor that would otherwise be applicable
to individual partners.

        The  servicing  compensation  to be  received  by  the  servicer  may be
questioned  by the IRS as  exceeding a  reasonable  fee for the  services  being
performed  in  exchange  for the  servicing  compensation,  and a portion of the
servicing  compensation  could  be  recharacterized  as  an  ownership  interest
retained by the servicer or other party in a portion of the interest payments to
be made with  respect to the Grantor  Trust  Fund's  assets.  In this  event,  a
certificate might be treated as a Stripped  Certificate  subject to the stripped
bond rules of Section 1286 of the Code,  and either the original  issue discount
or the  market  discount  rules.  See the  discussion  below  under  "--Stripped
Certificates".  Except as  discussed  below  under  "Stripped  Certificates"  or
"--Subordinated  Certificates,"  this discussion assumes that the servicing fees
paid to the servicer do not exceed reasonable servicing compensation.

        A purchaser of a Grantor Trust Security will be treated as purchasing an
interest  in each  asset in the  Grantor  Trust  Fund at a price  determined  by
allocating  the purchase price paid for the  certificate  among all asset of the
Grantor  Trust Fund in proportion to their fair market values at the time of the
purchase of the  certificate.  To the extent  that the  portion of the  purchase
price of a Grantor  Trust  Security  allocated to an asset of the Grantor  Trust
Fund is less than or greater than

                                      125



the stated  redemption price at maturity of the asset, the interest in the asset
will have been acquired at a discount or premium.  See  "--Market  Discount" and
"--Premium," below.

        The treatment of any discount on an asset of the Grantor Trust Fund will
depend on whether the  discount  represents  original  issue  discount or market
discount. Except as indicated otherwise in the applicable Prospectus Supplement,
it is not  expected  that any asset of the  Grantor  Trust  Fund  (other  than a
Stripped Agency Security or other  instrument  evidencing  ownership of specific
interest  and/or  principal  of a  particular  bond)  will have  original  issue
discount   (except  as  discussed   below  under  "Stripped   Certificates"   or
"Subordinated  Certificates").  For the rules governing original issue discount,
see "REMICs--Taxation of Owners of Regular  Securities--Original Issue Discount"
above.

        The  information  provided  to Grantor  Trust  Securityholders  will not
include  information  necessary to compute the amount of discount or premium, if
any, at which an interest in each asset of the Grantor Trust Fund is acquired.

        MARKET  DISCOUNT.  A  Grantor  Trust  Securityholder  that  acquires  an
undivided  interest in the  Grantor  Trust  Fund's  assets may be subject to the
market  discount  rules of Sections 1276 through 1278 to the extent an undivided
interest  in an asset of the  Grantor  Trust  Fund is  considered  to have  been
purchased at a "market discount".  For a discussion of the market discount rules
under the Code, see  "REMICs--Taxation  of Owners of Regular  Securities--Market
Discount" above. As discussed above, to the extent an asset of the Grantor Trust
Fund is a Stripped Agency Security or other instrument  evidencing  ownership of
specific  interest and/or  principal of a particular bond, it will be subject to
the rules  relating to original issue discount (in lieu of the rules relating to
market    discount).    See    "REMICs--Taxation    of   Owners    of    Regular
Securities--Original Issue Discount" above.

        PREMIUM.  To the extent a Grantor Trust  Securityholder is considered to
have  purchased an undivided  interest in an asset of the Grantor Trust Fund for
an amount that is greater  than the stated  redemption  price at maturity of the
interest,  the Grantor Trust Securityholder will be considered to have purchased
the interest in the asset with "amortizable bond premium" equal in amount to the
excess.  For a discussion of the rules  applicable to amortizable  bond premium,
see  "REMICs--Taxation  of Owners of  Regular  Securities--Amortizable  Premium"
above.

        STATUS OF THE GRANTOR  TRUST  SECURITIES.  Except for that  portion of a
Grantor Trust Fund consisting of unsecured home improvement  loans and except as
qualified below, a Grantor Trust Security owned by a:

        o   "domestic building and loan association"  within the meaning of Code
            Section  7701(a)(19)  will be considered  to represent  "loans . . .
            secured by an interest in real property"  within the meaning of Code
            Section 7701(a)(19)(C)(v), to the extent assets of the Trust consist
            of mortgage  loans and other  assets of the type  described  in that
            section of the Code.

        o   real estate  investment  trust will be considered to represent "real
            estate  assets" within the meaning of Code Section  856(c)(4)(A)  to
            the extent that the assets of the related Grantor Trust Fund consist
            of qualified  assets,  and  interest  income on those assets will be
            considered  "interest  on  obligations  secured by mortgages on real
            property"  to  that  extent  within  the  meaning  of  Code  Section
            856(c)(3)(B).

        o   REMIC will be considered to represent an "obligation  (including any
            participation or certificate of beneficial  ownership therein) which
            is principally  secured by an interest in real property"  within the
            meaning of Code Section  860G(a)(3)(A) to the


                                      126



            extent that the assets of the related  Grantor Trust Fund consist of
            "qualified mortgages" within the meaning of Code Section 860G(a)(3).

        It is not clear  whether  Grantor Trust  Certificates  that are Stripped
Certificates  (as  described  below  under  "Stripped  Certificates")  should be
treated as qualifying  under the Code  provisions  cited in the first two bullet
points  above to the same  extent as  Grantor  Trust  Certificates  that are not
Stripped  Certificate.  Grantor Trust  Securityholders are encouraged to consult
their own tax advisors concerning the  characterization of the  securityholder's
investment for federal income tax purposes.

        STRIPPED  CERTIFICATES.  Some classes of certificates  may be subject to
the  stripped  bond rules of Section  1286 of the Code and for  purposes of this
discussion  will be  referred  to as  "Stripped  Certificates."  In  general,  a
Stripped  Certificate will be subject to the stripped bond rules where there has
been a  separation  of  ownership  of the  right to  receive  some or all of the
principal  payments  on a  mortgage  loan held by the  Grantor  Trust  Fund from
ownership of the right to receive some or all of the related interest  payments.
Generally,  where a separation  has  occurred,  under the stripped bond rules of
Section  1286 of the Code,  the  holder of a right to  receive  a  principal  or
interest  payment on the bond is required to accrue into  income,  on a constant
yield basis under rules governing original issue discount (see "REMICs--Taxation
of Owners of  Regular  Securities--Original  Issue  Discount"),  the  difference
between the holder's initial  purchase price for the right to receive  principal
or interest,  and the principal or interest  payment to be received with respect
to that right.  However, a holder of a Stripped Certificate will account for any
discount  on the  Stripped  Certificate  (other  than an  interest  treated as a
"stripped  coupon") as market  discount  rather than original  issue discount if
either (i) the amount of original  issue  discount  with respect to the Stripped
Certificate  was treated as zero under the  original  issue  discount de minimis
rule when the Stripped  Certificate  was stripped or (ii) no more than 100 basis
points (including any amount of servicing in excess of reasonable  servicing) is
stripped from the mortgage assets.

        Certificates will constitute  Stripped  Certificates and will be subject
to these rules under various circumstances, including the following:

        o   if any  servicing  compensation  is deemed  to  exceed a  reasonable
            amount;

        o   if the  company or any other  party  retains a  retained  yield with
            respect to the assets held by the Grantor Trust Fund;

        o   if two or more classes of certificates  are issued  representing the
            right to non-pro  rata  percentages  of the  interest  or  principal
            payments on the Grantor Trust Fund's assets; or

        o   if   certificates   are  issued   which   represent   the  right  to
            interest-only payments or principal-only payments.

        The tax  treatment  of the  Stripped  Certificates  with  respect to the
application of the original  issue discount  provisions of the Code is currently
unclear.  However,  the trustee intends to treat each Stripped  Certificate as a
single  debt  instrument  issued  on the day it is  purchased  for  purposes  of
calculating  any original  issue  discount.  Holders may be obligated to perform
such calculation based on the day they acquire their Trust  Certificates  rather
than based on when the Grantor  Trust Fund  acquires the Stripped  Certificates.
Original issue discount with respect to a Stripped  Certificate must be included
in  ordinary  gross  income for  federal  income tax  purposes  as it accrues in
accordance   with  the  constant  yield  method  that  takes  into  account  the
compounding  of  interest  and this  accrual  of income may be in advance of the
receipt of any cash attributable to that income. See "REMICs--Taxation of Owners
of Regular  Securities--Original Issue Discount"

                                      127



above.  For purposes of applying the original issue  discount  provisions of the
Code, the issue price of a Stripped  Certificate will be the purchase price paid
by each holder of the Stripped  Certificate and the stated  redemption  price at
maturity  may  include  the  aggregate  amount of all  payments  to be made with
respect to the Stripped Certificate whether or not denominated as interest.  The
amount of original issue discount with respect to a Stripped  Certificate may be
treated as zero under the original  issue  discount de minimis  rules  described
above.

        The  precise  tax   treatment  of  Stripped   Coupon   Certificates   is
substantially  uncertain.  The Code could  read  literally  to require  that OID
computations be made for each payment from each mortgage loan. However, based on
IRS guidance,  it appears that all payments  from a mortgage  loan  underlying a
Stripped Coupon Certificate should be treated as a single installment obligation
subject  to the OID rules of the Code,  in which  case,  all  payments  from the
mortgage loan would be included in the mortgage loan's stated  redemption  price
at  maturity  for  purposes  of  calculating   income  on  the  Stripped  Coupon
Certificate under the OID rules of the Code.

        Based on current  authority it is unclear under what  circumstances,  if
any, the  prepayment of mortgage loans will give rise to a loss to the holder of
a  Stripped  Bond  Certificate  purchased  at a  premium  or a  Stripped  Coupon
Certificate.  The Code  provides  that a prepayment  assumption  must be used to
accrue income on any pool of debt instruments the yield on which can be affected
by prepayments. There is no guidance as to whether a Stripped Coupon Certificate
or a Stripped  Bond  Certificate  would  represent an interest in a pool of debt
instruments  for purposes of this Code  provision.  In  addition,  the manner in
which to take prepayments into account is uncertain. It is possible that no loss
may be available as a result of any particular prepayment, except perhaps to the
extent that even if no further  prepayments  were  received a  Certificateholder
would be  unable  to  recover  its  basis.  In  addition,  amounts  received  in
redemption for debt  instruments  issued by natural persons  purchased or issued
after June 8, 1997 are treated as received in exchange therefor (that is treated
the same as obligations  issued by  corporations).  This change could affect the
character of any loss.

        Holders of Stripped Bond  Certificates and Stripped Coupon  Certificates
are  encouraged  to consult  with their own tax  advisors  regarding  the proper
treatment of these certificates for federal income tax purposes.

        SUBORDINATED  CERTIFICATES.  In the event the Grantor  Trust Fund issues
two classes of Grantor Trust Securities that are identical except that one class
is a subordinate  class, with a relatively high certificate  pass-through  rate,
and the other is a senior class, with a relatively low certificate  pass-through
rate  (referred to in this  Prospectus  as the  "Subordinate  Certificates"  and
"Senior Certificates",  respectively),  the Grantor Trust Securityholders in the
aggregate  will be  deemed  to  have  acquired  the  following  assets:  (1) the
principal  portion of each  mortgage  loan plus a portion of the interest due on
each mortgage loan (the "Grantor Trust Fund Stripped  Bond"),  and (2) a portion
of the interest due on each  mortgage loan equal to the  difference  between the
Interest  Rate on the  Subordinate  Certificates  and the  Interest  Rate on the
Senior  Certificates,  if  any,  which  difference  is  then  multiplied  by the
Subordinate  Class  Percentage (the "Grantor Trust Fund Stripped  Coupon").  The
"Subordinate Class Percentage" equals the initial aggregate  principal amount of
the  Subordinate  Certificates  divided  by the  sum of  the  initial  aggregate
principal amount of the Subordinate  Certificates  and the Senior  Certificates.
The "Senior Class Percentage"  equals the initial aggregate  principal amount of
the Senior  Certificates  divided by the sum of the initial aggregate  principal
amount of the Subordinate Certificates and the Senior Certificates.

        The Senior Certificateholders in the aggregate will own the Senior Class
Percentage of the Grantor Trust Fund Stripped Bond and  accordingly  each Senior
Certificateholder  will be treated  as owning its pro rata share of such  asset.
The Senior Certificateholders will not own any portion of the Grantor Trust Fund
Stripped Coupon.  The Subordinate  Certificateholders  in the aggregate own both
the  Subordinate  Class  Percentage of the Grantor Trust Fund Stripped Bond plus
100% of

                                      128



the Grantor Trust Fund Stripped Coupon, if any, and accordingly each Subordinate
Certificateholder  will be treated as owning its pro rata share in both  assets.
The Grantor Trust Fund  Stripped  Bond will be treated as a "stripped  bond" and
the Grantor  Trust Fund  Stripped  Coupon will be treated as "stripped  coupons"
within the meaning of Section 1286 of the Code.

        Although not entirely  clear,  the  interest  income on the  Subordinate
Certificates and the portion of the servicing fee allocable to such certificates
that does not constitute  excess  servicing will be treated by the Grantor Trust
Fund as qualified  stated  interest,  assuming the interest  with respect to the
mortgage  loans  held by the  Grantor  Trust  Fund  would  otherwise  qualify as
qualified stated interest. Accordingly, except to the extent modified below, the
income of the  Subordinate  Certificates  will be reported in the same manner as
described generally above for holders of Senior Certificates.

        If the Subordinate  Certificateholders receive distribution of less than
their share of the Grantor  Trust Fund's  receipts of principal or interest (the
"Shortfall   Amount")   because  of  the   subordination   of  the   Subordinate
Certificates,  holders of Subordinate Certificates would probably be treated for
federal income tax purposes as if they had

        o   received as distributions their full share of receipts;

        o   paid over to the Senior  Certificateholders  an amount  equal to the
            Shortfall Amount; and

        o   retained the right to  reimbursement  of the relevant amounts to the
            extent  these  amounts  are  otherwise  available  as  a  result  of
            collections  on the  mortgage  loans  or  amounts  available  from a
            reserve account or other form of credit enhancement, if any.

Under this analysis,

        o   Subordinate  Certificateholders  would  be  required  to  accrue  as
            current income any interest income,  original issue discount, or (to
            the extent paid on assets of the Grantor Trust Fund) accrued  market
            discount  of the  Grantor  Trust  Fund that was a  component  of the
            Shortfall  Amount,  even  though that amount was in fact paid to the
            Senior Certificateholders;

        o   a loss would only be allowed to the  Subordinate  Certificateholders
            when their right to receive  reimbursement  of the Shortfall  Amount
            became worthless  (i.e.,  when it becomes clear that amount will not
            be available from any source to reimburse the loss); and

        o   reimbursement   of  the  Shortfall   Amount  prior  to  a  claim  of
            worthlessness   would  not  be   taxable   income   to   Subordinate
            Certificateholders  because  the amount was  previously  included in
            income.

Those  results  should  not  significantly  affect the  inclusion  of income for
Subordinate  Certificateholders  on the accrual method of accounting,  but could
accelerate  inclusion of income to  Subordinate  Certificateholders  on the cash
method  of  accounting  by,  in  effect,  placing  them on the  accrual  method.
Moreover,  the character and timing of loss deductions are unclear.  Subordinate
Certificateholders  are strongly  encouraged  to consult  their own tax advisors
regarding the appropriate  timing,  amount and character of any losses sustained
with respect to the Subordinate  Certificates  including any loss resulting from
the failure to recover previously accrued interest or discount income.

                                      129



        ELECTION TO TREAT ALL INTEREST AS ORIGINAL ISSUE DISCOUNT.  The Treasury
Regulations   relating  to  original  issue  discount  permit  a  Grantor  Trust
Securityholder to elect to accrue all interest,  discount,  including de minimis
market  or  original  issue  discount,  reduced  by any  premium,  in  income as
interest,  based on a constant yield method. If an election were to be made with
respect to an interest  in a mortgage  loan with  market  discount,  the Grantor
Trust  Securityholder  would be deemed to have made an  election  to  include in
income  currently  market  discount  with respect to all other debt  instruments
having market discount that the Grantor Trust Securityholder acquires during the
year of the election or afterward.  See "--Market Discount" above.  Similarly, a
Grantor  Trust  Securityholder  that makes this  election  for an  interest in a
mortgage  loan  that is  acquired  at a  premium  will be deemed to have made an
election to amortize  bond premium with respect to all debt  instruments  having
amortizable  bond  premium  that the Grantor  Trust  Securityholder  owns at the
beginning of the first  taxable  year to which the election  applies or acquires
afterward. See "--Premium" above. The election to accrue interest,  discount and
premium on a constant  yield method with respect to a Grantor Trust  Security is
irrevocable.

        PREPAYMENTS. The Taxpayer Relief Act of 1997 (the "1997 Act") contains a
provision  requiring original issue discount on any pool of debt instruments the
yield on which may be affected by reason of  prepayments  be  calculated  taking
into account the  Prepayment  Assumption  and requiring the discount to be taken
into income on the basis of a constant yield to assumed  maturity taking account
of actual prepayments.

        SALE OR  EXCHANGE  OF A GRANTOR  TRUST  SECURITY.  Sale or exchange of a
Grantor Trust  Security  prior to its maturity will result in gain or loss equal
to the difference,  if any,  between the amount  realized,  exclusive of amounts
attributable  to accrued and unpaid  interest (which will be treated as ordinary
income  allocable  to the related  asset of the  Grantor  Trust  Fund),  and the
owner's  adjusted  basis in the  Grantor  Trust  Security.  The  adjusted  basis
generally will equal the seller's cost for the Grantor Trust Security, increased
by the original issue discount and any market discount  included in the seller's
gross income with respect to the Grantor Trust  Security,  and reduced,  but not
below zero, by any premium amortized by the seller and by principal  payments on
the Grantor Trust Security  previously  received by the seller. The gain or loss
will,  except as discussed  below, be capital gain or loss to an owner for which
the assets of the Grantor Trust Fund represented by a Grantor Trust Security are
"capital assets" within the meaning of Section 1221. A capital gain or loss will
be  long-term  or  short-term  depending  on  whether or not the  Grantor  Trust
Security has been owned for the long-term capital gain holding period, currently
more than one year.

        Notwithstanding the foregoing, any gain realized on the sale or exchange
of a  Grantor  Trust  Security  will be  ordinary  income  to the  extent of the
seller's  interest in accrued  market  discount on Grantor Trust Fund assets not
previously taken into income. See "--Market Discount," above.  Further,  Grantor
Trust  Securities  will be  "evidences  of  indebtedness"  within the meaning of
Section  582(c)(1)  to the extent the assets of the  grantor  trust  would be so
treated.  Accordingly,  gain or loss recognized from the sale of a Grantor Trust
Security by a bank or thrift  institution to which such section  applied will be
treated as ordinary gain or loss to the extent selling the assets of the grantor
trust directly would be so treated.

        FOREIGN  INVESTORS IN GRANTOR  TRUST  SECURITIES.  A holder of a Grantor
Trust  Security  who is not a "U.S.  person" (as defined  above at  "REMICs--Tax
Related Restrictions on Transfer of Residual Securities--Foreign Investors") and
is not  subject  to federal  income  tax as a result of any  direct or  indirect
connection  to the United  States other than its  ownership  of a Grantor  Trust
Security  generally  will not be subject to United States income or  withholding
tax in respect of payments of interest or original issue discount on its Grantor
Trust  Security  to the  extent  attributable  to debt  obligations  held by the
Grantor Trust Fund that were originated  after July 18, 1984,  provided that the
Grantor  Trust  Securityholder  complies to the extent  necessary  with  certain
certification  requirements  which  generally  relate  to  the  identity  of the
beneficial  owner and the status of the beneficial owner as a person that is not
a U.S.  person.  Interest or original issue

                                      130



discount on a Grantor Trust Security  attributable to debt  obligations  held by
the  Grantor  Trust  Fund that were  originated  prior to July 19,  1984 will be
subject to a 30% withholding tax (unless such tax is reduced or eliminated by an
applicable tax treaty).  All holders of Grantor Trust  Securities are encouraged
to consult their tax advisors regarding the tax documentation and certifications
that must be provided to secure any  applicable  exemptions  from United  States
withholding taxes.

        Any capital gain realized on the sale or other taxable  disposition of a
Grantor   Trust   Security   by  a  Non-U.S.   Person  (as   defined   above  at
"REMICs--Taxation of Certain Foreign  Investors--Regular  Securities") generally
will be exempt from United States federal income and withholding  tax,  provided
that (i) such gain is not  effectively  connected with the conduct of a trade or
business in the United States by the Non-U.S.  Person and (ii) in the case of an
individual  Non-U.S.  Person,  the Non-U.S.  Person is not present in the United
States for 183 days or more in the taxable year.

        If the interest, gain or income with respect to a Grantor Trust Security
held by a Non-U.S.  Person is effectively  connected with the conduct of a trade
or business in the United States by the Non-U.S.  Person  (although  exempt from
the withholding  tax previously  discussed if the holder provides an appropriate
statement establishing that such income is so effectively connected), the holder
generally  will be subject to United States  federal income tax on the interest,
gain or income at regular federal income tax rates. In this regard,  real estate
acquired by a Grantor Trust as a result of foreclosure or in lieu of foreclosure
could cause a foreign holder to have  "effectively  connected  income" or a U.S.
tax filing  obligation even in the absence of such income.  In addition,  if the
Non-U.S. Person is a foreign corporation,  it may be subject to a branch profits
tax equal to 30% of its "effectively connected earnings and profits," within the
meaning of the Code, for the taxable year, as adjusted for certain items, unless
it qualifies for a lower rate under an applicable tax treaty (as modified by the
branch profits tax rules).

        BACKUP  WITHHOLDING.  Distributions made on the Grantor Trust Securities
and proceeds from the sale of the Grantor Trust  Securities will be subject to a
"backup"  withholding tax if, in general, the Grantor Trust Securityholder fails
to comply with  particular  identification  procedures,  unless the holder is an
exempt  recipient  under  applicable  provisions  of the Code and, if necessary,
demonstrates  such status.  Any amounts so withheld would be refunded by the IRS
or  allowable as a credit  against the Grantor  Trust  Securityholder's  federal
income tax.

PARTNERSHIP TRUST FUNDS AND DISREGARDED ENTITIES

        CLASSIFICATION OF ISSUING ENTITIES

        For each series of Partnership Certificates or Debt Securities,  Federal
Tax  Counsel  will  deliver its  opinion  that the issuing  entity will not be a
taxable mortgage pool or an association (or publicly traded partnership) taxable
as a corporation for federal income tax purposes.  This opinion will be based on
the assumption that the parties to the related  Agreement and related  documents
will comply with the terms of those documents.

        TAXATION OF DEBT SECURITYHOLDERS

        The depositor will agree,  and the  securityholders  will agree by their
purchase of Debt  Securities,  to treat the Debt  Securities as debt for federal
income tax purposes.  No regulations,  published rulings,  or judicial decisions
exist that  discuss  the  characterization  for federal  income tax  purposes of
securities with terms  substantially  the same as the Debt Securities.  However,
for each series of Debt Securities, Federal Tax Counsel will deliver its opinion
that the Debt Securities  will be classified as indebtedness  for federal income
tax purposes.  The discussion  below assumes this  characterization  of the Debt
Securities is correct.

                                      131



        If,  contrary to the opinion of counsel,  the Internal  Revenue  Service
successfully  asserted that the Debt Securities were not debt for federal income
tax  purposes,  the Debt  Securities  might be treated as equity  interests in a
Partnership  Trust Fund.  If so  treated,  the  Partnership  Trust Fund might be
treated as a publicly traded  partnership that would be taxable as a corporation
unless it met  particular  qualifying  income tests,  and the resulting  taxable
corporation  would not be able to reduce its taxable  income by  deductions  for
interest expense on Debt Securities  recharacterized as equity. Treatment of the
Debt  Securities  as equity  interests in a  partnership  could have adverse tax
consequences  to some  holders,  even if the  Partnership  Trust  Fund  were not
treated as a publicly traded partnership taxable as a corporation.  For example,
income  allocable to foreign  holders  might be subject to United States tax and
United States tax return filing and withholding  requirements,  income allocable
to tax-exempt holders might constitute  "unrelated  business taxable income" (if
some, but not all, of the Debt  Securities were  recharacterized  as equity in a
partnership),  individual  holders  might be  subject  to  limitations  on their
ability to deduct  their share of the  Partnership  Trust Fund's  expenses,  and
income from the  Partnership  Trust Fund's  assets would be taxable to owners of
Debt Securities  without regard to whether cash  distributions  are made to such
owners and without regard to the owners' method of tax accounting.

        Except for the  treatment of the  allocation  of Realized  Losses,  Debt
Securities  generally  will be subject to the same rules of  taxation as Regular
Securities  issued  by a REMIC,  as  described  above,  except  that (1)  income
reportable on Debt  Securities is not required to be reported  under the accrual
method unless the holder  otherwise  uses the accrual method and (2) the special
110% yield rule  treating a portion of the gain on sale or exchange of a Regular
Security  as  ordinary   income  is  inapplicable   to  Debt   Securities.   See
"--REMICs--Taxation  of Owners of Regular Securities" and "--Sale or Exchange of
Regular Securities."

        ALLOCATIONS OF REALIZED LOSSES.

        The  manner  in which  losses  are  claimed  on the Notes as a result of
defaults by the  underlying  obligors is complex  and differs  depending  on the
characterization  of the person  considered  the issuer of the Notes for federal
tax  purposes.  Whether  the Notes are  governed by the loss rules for bad debts
under Code  Section  166 or for  worthless  securities  under Code  Section  165
depends on whether the Notes are considered issued by a corporation. If there is
a single  corporate  holder of the  Certificates  constituting all of the equity
interests in the issuing Partnership Trust Fund, then the issuing entity will be
a disregarded  entity as separate from its equity owner and if such equity owner
is a corporation,  the Notes will be considered issued by a corporation  subject
to the loss rules of Code Section 165 (which  affects both timing and  character
of loss for corporate  taxpayers,  and  character and possibly  timing for other
taxpayers).  If the Notes are  considered  issued by a grantor  trust,  then the
notes  may  be   treated  as  issued  in   proportion   to  the  nature  of  the
Certificateholders  (e.g.,  if some  Certificateholders  are natural  persons or
partnerships and some are corporations, losses on the Notes would be governed in
part by Code  Section  166 and in part by Code  Section  165).  If the Notes are
considered  issued by a  partnership  then they would be  governed  by the rules
under Code Section 166 the same as a REMIC.  Investors are encouraged to consult
their  tax  advisors  as to the  character  and  timing  of any loss that can be
claimed with respect to a Note.

        Further, for federal income tax purposes,  (i) Debt Securities held by a
thrift  institution  taxed as a domestic  building and loan association will not
constitute  "loans . . . secured by an  interest  in real  property"  within the
meaning  of  Section  7701(a)(19)(C)(v)  of the  Code;  (ii)  interest  on  Debt
Securities  held by a real  estate  investment  trust  will  not be  treated  as
"interest on  obligations  secured by mortgages on real property or on interests
in real property  "within the meaning of Code Section  856(c)(3)(B);  (iii) Debt
Securities  held by a real estate  investment  trust will not  constitute  "real
estate  assets"  or  "Government  securities"  within  the  meaning  of  Section
856(c)(4)(A) of the Code;  (iv) Debt  Securities held by a regulated  investment
company  will not  constitute  "Government  securities"  within  the  meaning of
Section 851(b)(3)(A)(i) of the Code; and

                                      132



(v)  Debt  Securities  will not  constitute  "qualified  mortgages"  with in the
meaning of Section 860G(a)(3) of the Code for REMICs.

        TAXATION OF OWNERS OF PARTNERSHIP CERTIFICATES

(1)     Treatment as a Partnership Trust Fund

        The correct  characterization  of an issuing entity that has issued debt
and is not otherwise taxed as a corporation is uncertain.  If the issuing entity
has only a single class of equity and the Trustee does not have the authority to
accept any  additional  assets  after the  initial  acquisition  of  receivables
(except  within a certain  prescribed  pre-funding  period not  exceeding  three
months) and has very limited powers of investment (for example does not hold any
reserve fund that could ultimately flow to the  Certificateholders if not needed
to pay the Noteholders) the issuing entity could qualify as a grantor trust with
an interest expense. As a consequence,  each Certificateholder  would be treated
as  owning a pro rata  share of the  issuing  entity's  assets,  earning  income
thereon and incurring the expenses of the issuing entity (including the interest
expense on the Notes).  See "Grantor  Trusts." If an issuing  entity that issues
Notes intends to take the position that  Certificateholders  hold interests in a
grantor  trust it will be disclosed  in the related  prospectus  supplement.  In
addition,  it is possible that an issuing entity that issued Notes could qualify
as a partnership  eligible to make an election under Section 761 to not be taxed
under the main partnership  provisions of the Code (although  certain  ancillary
provisions,  including  the rules  relating  to audits  of  partnerships,  would
continue  to apply).  Such an  election  would  cause  Certificateholders  to be
treated  as  essentially  the same as holding an  interest  in a grantor  trust.
However,  the IRS has  recently  taken a  narrow  interpretation  of the type of
entities  that  qualify  for this  election,  which may not  include  an issuing
entity.  If an  issuing  entity  that is treated  as a  partnership  has made an
election under Section 761 to be excluded from the main  partnership  provisions
of the Code this will be disclosed in the related  prospectus  supplement  along
with a description of the  consequences of making such an election.  If there is
only one  Certificateholder  in an issuing  entity  that  represents  all of the
equity of the  issuing  entity for federal  income tax  purposes,  the  separate
existence of the issuing entity is  disregarded,  and the  Certificateholder  is
treated  as the owner of all of the  assets  of the  issuing  entity  and as the
issuer of the Notes of the issuing entity for federal  income tax purposes.  For
all other Issuing  entities that issue Notes,  the  Partnership  Trust Fund will
agree,  and  the  related  owners  of  Partnership  Certificates   ("Partnership
Certificate  Owners") will agree by their purchase of Partnership  Certificates,
if  there  is  more  than  one  Partnership  Certificate  Owner,  to  treat  the
Partnership Trust Fund as a partnership for purposes of federal and state income
tax,  franchise  tax and any other tax  measured  in whole or in part by income,
with the  assets of the  partnership  being the assets  held by the  Partnership
Trust Fund, the partners of the partnership  being the  Partnership  Certificate
Owners,  including,  to the extent  relevant,  the  depositor in its capacity as
recipient of distributions  from any reserve fund, and the Debt  Securities,  if
any, being debt of the partnership,  and if there is one Partnership Certificate
Owner, to treat the Partnership  Certificate Owner as the owner of the assets of
the  Partnership  Trust  Fund  and to  treat  the  Partnership  Trust  Fund as a
disregarded  entity.  However,  the proper  characterization  of the arrangement
involving the  Partnership  Trust Fund, the Partnership  Certificates,  the Debt
Securities  and the  depositor is not certain  because  there is no authority on
transactions closely comparable to that contemplated in this prospectus.

        A variety of alternative  characterizations  are possible.  For example,
because the Partnership  Certificates  have certain features  characteristic  of
debt, the Partnership  Certificates  might be considered debt of the Partnership
Trust Fund. Generally,  provided such Partnership  Certificates are issued at or
close to face value,  any such  characterization  would not result in materially
adverse tax  consequences to holders of Partnership  Certificates as compared to
the consequences  from treatment of the Partnership  Certificates as equity in a
partnership,   described  below.  The  following  discussion  assumes  that  the
Partnership  Certificates  represent  equity  interests  in a  partnership.  The
following discussion also assumes that all payments on the

                                      133



Partnership   Certificates  are  denominated  in  U.S.  dollars,   none  of  the
Partnership  Certificates  have Interest Rates which would qualify as contingent
interest under the Treasury regulations relating to original issue discount, and
that a series of securities includes a single class of Partnership Certificates.
If these  conditions  are not  satisfied  with  respect  to any given  series of
Partnership  Certificates,  additional tax  considerations  with respect to such
Partnership   Certificates  will  be  disclosed  in  the  applicable  prospectus
supplement.

(2)     Partnership Taxation

        As a  partnership,  the  Partnership  Trust  Fund will not be subject to
federal income tax. Rather, each Partnership  Certificate Owner will be required
to take into account  separately the Partnership  Certificate  Owner's allocable
share of income, gains, losses,  deductions and credits of the Partnership Trust
Fund, whether or not there is a corresponding cash distribution.  The Trust will
generally  be required  to use an accrual  method of  accounting  and a tax year
based on the tax year of its  Certificateholders.  Thus, cash basis holders will
in effect be required to report income from the Partnership  Certificates on the
accrual basis and Partnership  Certificate Owners may become liable for taxes on
Partnership  Trust  Fund  income  even if they have not  received  cash from the
Partnership  Trust Fund to pay the taxes.  The  Partnership  Trust Fund's income
will consist  primarily of interest  and finance  charges  earned on the related
mortgage loans, including appropriate adjustments for market discount,  original
issue discount and bond premium,  and any gain upon collection or disposition of
the mortgage loans.

        The  Partnership  Trust  Fund's  deductions  will  consist  primarily of
interest accruing with respect to the Debt Securities, servicing and other fees,
and losses or deductions upon collection or disposition of mortgage loans.

        The  tax  items  of a  partnership  are  allocable  to the  partners  in
accordance with the Code,  Treasury  regulations  and the partnership  agreement
(i.e.,  the Agreement and related  documents).  To the extent that there is more
than one class of equity  (or  potentially  more than one class of  equity)  the
related prospectus  supplement will describe the manner in which income from the
assets of the issuing entity will be allocated.

        Assuming Debt Securities are also issued,  all or  substantially  all of
the  taxable  income  allocated  to a  Partnership  Certificate  Owner that is a
pension,  profit sharing or employee  benefit plan or other  tax-exempt  entity,
including an individual  retirement account, will constitute "unrelated business
taxable income" generally taxable to the holder under the Code.

        An  individual  taxpayer's  share of expenses of the  Partnership  Trust
Fund,  including  fees to the  servicer,  but not  interest  expense,  would  be
miscellaneous  itemized  deductions and thus  deductible only to the extent such
expenses plus all other miscellaneous itemized deductions exceeds two percent of
the individual's  adjusted gross income. An individual  taxpayer will be allowed
no deduction for his share of expenses of the Partnership Trust Fund, other than
interest, in determining his liability for alternative minimum tax. In addition,
Section 68 of the Code provides that the amount of itemized deductions otherwise
allowable for the taxable year for an  individual  whose  adjusted  gross income
exceeds a prescribed threshold amount will be reduced by the lesser of (1) 3% of
the  excess  of  adjusted  gross  income  over the  specified  threshold  amount
(adjusted  annually  for  inflation)  or  (2)  80%  of the  amount  of  itemized
deductions  otherwise  allowable for the applicable  taxable year.  Accordingly,
deductions  might be disallowed to the  individual in whole or in part and might
result in the Partnership  Certificate  Owner being taxed on an amount of income
that exceeds the amount of cash actually distributed to the holder over the life
of the  Partnership  Trust Fund.  The reduction  under Code Section 68 is itself
reduced by one-third  for taxable years  beginning in 2006 and 2007,  two-thirds
for taxable  years  beginning  in 2008 and 2009,  and fully  reduced for taxable
years  beginning  in  2010  with  no  reduction  thereafter.  In the  case  of a
partnership  that  has 100 or more  partners  and  elects  to be  treated  as an
"electing

                                      134



large partnership," 70% of that partnership's  miscellaneous itemized deductions
will be disallowed,  although the remaining deductions will generally be allowed
at the  partnership  level and will not be  subject  to the 2% floor  that would
otherwise be applicable to individual partners.

        The Partnership Trust Fund intends to make all tax calculations relating
to income and  allocations  to  Partnership  Certificate  Owners on an aggregate
basis to the extent  relevant.  If the IRS were to require that the calculations
be made separately for each mortgage loan, the  calculations  may result in some
timing and character differences under some circumstances.

(3)     Discount and Premium

        The purchase  price paid by the  Partnership  Trust Fund for the related
mortgage  loans may be greater or less than the remaining  principal  balance of
the mortgage loans at the time of purchase.  If so, the mortgage loans will have
been  acquired  at a  premium  or  market  discount,  as the  case  may be.  See
"REMICs--Taxation of Owners of Regular Securities--Acquisition  Premium" and "--
Market Discount" above. As indicated above, the Partnership Trust Fund will make
this  calculation on an aggregate  basis,  but it is possible that the IRS might
require  that  it be  recomputed  on a  mortgage  loan-by-mortgage  loan  basis.
Further,  with  respect  to any asset of the  Partnership  Trust  Fund that is a
Stripped Agency Security or other  instrument  evidencing  ownership of specific
interest and/or  principal of a particular bond, it will be subject to the rules
relating to original  issue discount with respect to such security or instrument
(in lieu of the rules relating to market  discount).  See  "REMICs--Taxation  of
Owners of Regular Securities--Original Issue Discount" above.

        If the  Partnership  Trust Fund acquires the mortgage  loans at a market
discount or premium, the Partnership Trust Fund will elect to include any market
discount in income  currently as it accrues over the life of the mortgage  loans
or to offset any premium  against  interest  income on the  mortgage  loans.  As
indicated  above, a portion of the market discount  income or premium  deduction
may be allocated to Partnership Certificate Owners.

(4)     Section 708 Termination

        Under Section 708 of the Code, the Partnership Trust Fund will be deemed
to terminate  for federal  income tax purposes if 50% or more of the capital and
profits  interests in the Partnership  Trust Fund are sold or exchanged within a
12-month  period.  If a termination  occurs under  Section 708 of the Code,  the
Partnership  Trust Fund will be  considered  to  contribute  its assets to a new
Partnership Trust Fund, which would be treated as a new partnership, in exchange
for Partnership  Certificates  in the new  Partnership  Trust Fund. The original
Partnership  Trust  Fund  will  then be deemed  to  distribute  the  Partnership
Certificates  in the  new  Partnership  Trust  Fund to  each  of the  owners  of
Partnership  Certificates in the original  Partnership Trust Fund in liquidation
of the original  Partnership  Trust Fund.  The  Partnership  Trust Fund will not
comply  with  particular   technical   requirements  that  might  apply  when  a
constructive  termination occurs. As a result, the Partnership Trust Fund may be
subject  to some  tax  penalties  and may  incur  additional  expenses  if it is
required to comply with those requirements.  Furthermore,  the Partnership Trust
Fund might not be able to comply with these requirements due to lack of data.

(5)     Disposition of Partnership Certificates

        Generally,  capital  gain  or  loss  will  be  recognized  on a sale  of
Partnership Certificates in an amount equal to the difference between the amount
realized and the seller's tax basis in the  Partnership  Certificates  sold. Any
gain  or loss  would  be  long-term  capital  gain  or  loss if the  Partnership
Certificate Owner's holding period exceeded one year. A Partnership  Certificate
Owner's tax basis in a Partnership  Certificate  will generally  equal its cost,
increased  by its  share of  Partnership  Trust  Fund  income  allocable  to the
Partnership Certificate Owner and decreased by

                                      135



any  distributions  received or losses allocated with respect to the Partnership
Certificate. In addition, both the tax basis in the Partnership Certificates and
the amount  realized on a sale of a  Partnership  Certificate  would include the
Partnership Certificate Owner's share, determined under Treasury Regulations, of
the Debt  Securities  and other  liabilities  of the  Partnership  Trust Fund. A
Partnership  Certificate Owner acquiring  Partnership  Certificates at different
prices will  generally be required to maintain a single  aggregate  adjusted tax
basis in the Partnership  Certificates  and, upon a sale or other disposition of
some of the  Partnership  Certificates,  allocate a portion of the aggregate tax
basis to the Partnership  Certificates  sold, rather than maintaining a separate
tax basis in each Partnership Certificate for purposes of computing gain or loss
on a sale of that  Partnership  Certificate.  A portion holding rule is applied,
however, if a Certificateholder has held some of its interest in the Partnership
Trust Fund for one year or less and some of its  interest for more than one year
and a "by lot" identification is not permitted.

        If a Partnership Certificate Owner is required to recognize an aggregate
amount of income (not  including  income  attributable  to  disallowed  itemized
deductions  described above) over the life of the Partnership  Certificates that
exceeds  the  aggregate  cash  distributions  with  respect  to the  Partnership
Certificates,  the excess will  generally  give rise to a capital  loss upon the
retirement of the Partnership Certificates.

(6)     Allocations Between Transferors and Transferees

        In general,  the Partnership Trust Fund's taxable income and losses will
be determined each Due Period and the tax items for a particular Due Period will
be apportioned  among the  Partnership  Certificate  Owners in proportion to the
principal  amount of Partnership  Certificates  owned by them as of the close of
the last day of that Due Period.  As a result, a Partnership  Certificate  Owner
purchasing  Partnership  Certificates  may be  allocated  tax items,  which will
affect the  purchaser's  tax  liability and tax basis,  attributable  to periods
before the actual transaction.

        The use of a Due Period  convention  may not be  permitted  by  existing
Treasury regulations. If a Due Period convention is not allowed, or only applies
to  transfers  of less than all of the  partner's  interest,  taxable  income or
losses of the Partnership  Trust Fund might be reallocated among the Partnership
Certificate  Owners.  The Partnership Trust Fund's method of allocation  between
transferors and  transferees may be revised to conform to a method  permitted by
future laws, regulations or other IRS guidance.

(7)     Section 731 Distributions

        In the case of any distribution to a Partnership  Certificate  Owner, no
gain will be recognized to that Partnership Certificate Owner to the extent that
the amount of any money distributed for that Partnership Certificate exceeds the
adjusted  basis  of  that  Partnership   Certificate  Owner's  interest  in  the
Partnership  Certificate.  To the extent  that the  amount of money  distributed
exceeds  that  Partnership  Certificate  Owner's  adjusted  basis,  gain will be
currently  recognized.  In  the  case  of  any  distribution  to  a  Partnership
Certificate  Owner,  no loss will be recognized  except upon a  distribution  in
liquidation  of a Partnership  Certificate  Owner's  interest.  Any gain or loss
recognized by a Partnership  Certificate Owner generally will be capital gain or
loss.

(8)     Section 754 Election

        In the event that a Partnership  Certificate Owner sells its Partnership
Certificates at a profit (or loss), the purchasing Partnership Certificate Owner
will have a higher (or lower)  basis in the  Partnership  Certificates  than the
selling  Partnership  Certificate  Owner had.  The tax basis of the  Partnership
Trust Fund's assets will not be adjusted to reflect that higher (or lower) basis
unless there is a "substantial  basis  reduction"  within the meaning of Section
734 of the Code or unless the trust were to file an election  under  Section 754
of the Code. Because the trust will most likely

                                      136



qualify as a "securitization  partnership"  within the meaning of Section 743(f)
of the Code, there will not be a substantial basis reduction with respect to the
sale of the certificates.  With respect to the election under Section 754 of the
Code, in order to avoid the  administrative  complexities that would be involved
in  keeping  accurate   accounting  records,  as  well  as  potentially  onerous
information reporting requirements,  the Partnership Trust Fund current does not
intend  to  make  an  election  under  Section  754 of the  Code.  As a  result,
Partnership  Certificate Owners might be allocated a greater or lesser amount of
Partnership  Trust  Fund  income  than would be  appropriate  based on their own
purchase price for Partnership Certificates.

(9)     Administrative Matters

        The  trustee  is  required  to keep or  cause  to be kept  complete  and
accurate books of the Partnership Trust Fund. Except as disclosed in the related
prospectus  supplement,  the trustee will file a partnership  information return
(IRS Form 1065) with the IRS for each taxable year of the Partnership Trust Fund
and will report each Partnership Certificate Owner's allocable share of items of
Partnership Trust Fund income and expense to Partnership  Certificate Owners and
the IRS on Schedule  K-1. The  Partnership  Trust Fund will provide the Schedule
K-1 information to nominees that fail to provide the Partnership Trust Fund with
the information  statement  described below and the nominees will be required to
forward  this   information  to  the  beneficial   owners  of  the   Partnership
Certificates.   Generally,  holders  must  timely  file  tax  returns  that  are
consistent with the information return filed by the Partnership Trust Fund or be
subject  to   penalties   unless  the  holder   notifies  the  IRS  of  all  the
inconsistencies.

        Under  Section  6031 of the Code,  any  person  that  holds  Partnership
Certificates  as a nominee at any time  during a calendar  year is  required  to
furnish  the  Partnership  Trust  Fund  with  a  statement  containing  specific
information  on  the  nominee,   the  beneficial   owners  and  the  Partnership
Certificates  so held.  The  information  includes  (1) the  name,  address  and
taxpayer  identification  number of the  nominee  and (2) as to each  beneficial
owner

        o   the name, address and identification number of such person,

        o   whether such person is a United States person,  a tax-exempt  entity
            or a  foreign  government,  an  international  organization,  or any
            wholly owned agency or  instrumentality  of either of the foregoing,
            and

        o   particular  information on Partnership  Certificates that were held,
            bought or sold on behalf of the person throughout the year.

In  addition,   brokers  and  financial   institutions   that  hold  Partnership
Certificates  through  a  nominee  are  required  to  furnish  directly  to  the
Partnership  Trust Fund  information  as to  themselves  and their  ownership of
Partnership Certificates.  A clearing agency registered under Section 17A of the
Exchange  Act is not  required  to  furnish  any  information  statement  to the
Partnership Trust Fund. The information  referred to above for any calendar year
must be  furnished  to the  Partnership  Trust Fund on or before  the  following
January 31. Nominees,  brokers and financial  institutions  that fail to provide
the Partnership  Trust Fund with the information  described above may be subject
to penalties.

        Unless another  designation is made, the depositor will be designated as
the tax  matters  partner  for each  Partnership  Trust Fund in the  pooling and
servicing  agreement and, as the tax matters  partner,  will be responsible  for
representing the Partnership  Certificate  Owners in some specific disputes with
the IRS. The Code provides for administrative examination of a partnership as if
the partnership were a separate and distinct taxpayer. Generally, the statute of
limitations  for  partnership  items does not  expire  before the later of three
years after the date on which the

                                      137



partnership  information  return is filed or the last day for  filing the return
for the applicable year,  determined  without regard to extensions.  Any adverse
determination  following an audit of the return of the Partnership Trust Fund by
the appropriate  taxing authorities could result in an adjustment of the returns
of  the  Partnership  Certificate  Owners,  and,  under  some  circumstances,  a
Partnership  Certificate  Owner may be precluded  from  separately  litigating a
proposed  adjustment to the items of the  Partnership  Trust Fund. An adjustment
could also result in an audit of a Partnership  Certificate  Owner's returns and
adjustments  of items not  related to the  income and losses of the  Partnership
Trust Fund.

        A special audit system exists for  qualifying  large  partnerships  that
have elected to apply a simplified  flow-through reporting system under Sections
771  through  777 of the Code.  Unless  otherwise  specified  in the  applicable
prospectus  supplement,  a  Partnership  Trust  Fund will not elect to apply the
simplified flow-through reporting system.

(10)    Taxation of Certain Foreign Partnership Certificate Owners

        As used below,  the term  "Non-United  States Owner" means a Partnership
Certificate Owner that is not a U.S. Person, as defined under  "REMICs--Taxation
of Owners of  Residual  Securities--Tax  Related  Restrictions  on  Transfer  of
Residual Securities--Foreign Investors," above.

        It is not clear whether the  Partnership  Trust Fund would be considered
to be  engaged in a trade or  business  in the United  States  for  purposes  of
federal withholding taxes with respect to Non-United States Owners because there
is no clear authority dealing with that issue under facts substantially  similar
to those  described in this  Prospectus.  Although it is not  expected  that the
Partnership  Trust Fund would be  engaged in a trade or  business  in the United
States for these  purposes,  the  Partnership  Trust Fund will withhold as if it
were so engaged in order to protect  the  Partnership  Trust Fund from  possible
adverse  consequences  of a failure  to  withhold.  The  Partnership  Trust Fund
expects to withhold on the portion of its taxable  income that is  allocable  to
Non-United  States Owners pursuant to Section 1446 of the Code, as if the income
were  effectively  connected to a U.S.  trade or business,  at a rate of 35% for
Non-United  States  Owners  that are taxable as  corporations  and 39.6% for all
other Non-United States Owners.

        Subsequent  adoption of Treasury  regulations  or the  issuance of other
administrative  pronouncements  may require the Partnership Trust Fund to change
its withholding procedures.

        Each Non-United States Owner might be required to file a U.S. individual
or  corporate  income tax  return on its share of the income of the  Partnership
Trust Fund including,  in the case of a corporation,  a return in respect of the
branch profits tax. Assuming the Partnership Trust Fund is not engaged in a U.S.
trade or business,  a Non-United States Owner would be entitled to a refund with
respect to all or a portion of taxes withheld by the Partnership  Trust Fund if,
in  particular,  the Owner's  allocable  share of interest from the  Partnership
Trust Fund constituted "portfolio interest" under the Code.

        The interest, however, may not constitute "portfolio interest" if, among
other  reasons,  the underlying  obligation is not in registered  form or if the
interest is determined  without  regard to the income of the  Partnership  Trust
Fund,  in the  later  case,  the  interest  being  properly  characterized  as a
guaranteed  payment  under  Section  707(c) of the Code.  If this were the case,
Non-United  States Owners would be subject to a United States federal income and
withholding  tax at a rate of 30 percent on the  Partnership  Trust Fund's gross
income,  without  any  deductions  or other  allowances  for costs and  expenses
incurred in producing the income,  unless  reduced or eliminated  pursuant to an
applicable  treaty.  In this  case,  a  Non-United  States  Owner  would only be
entitled  to a refund for that  portion of the taxes,  if any,  in excess of the
taxes that should have been withheld with respect to the interest.

                                      138



(11)    Backup Withholding

        Distributions made on the Partnership Certificates and proceeds from the
sale of the Partnership  Certificates will be subject to a "backup"  withholding
tax if, in  general,  the  Partnership  Certificate  Owner  fails to comply with
particular identification  procedures,  unless the holder is an exempt recipient
under  applicable  provisions of the Code and, if necessary,  demonstrates  such
status.  Any amounts so withheld  would be refunded by the IRS or allowable as a
credit against the Non-United States Owner's federal income tax.

(12)    Reportable Transactions

        Pursuant to  recently  enacted  legislation,  a penalty in the amount of
$10,000 in the case of a natural person and $50,000 in any other case in imposed
on any  taxpayer  that fails to timely file an  information  return with the IRS
with respect to a  "reportable  transaction"  (as defined in Section 6011 of the
Code). The rules defining  "reportable  transactions" are complex,  and include,
but are not limited to,  transactions  that result in certain losses that exceed
threshold  amounts.  Prospective  investors are advised to consult their own tax
advisers  regarding  any  possible  disclosure  obligations  in  light  of their
particular circumstances.

CONSEQUENCES FOR PARTICULAR INVESTORS

        The federal tax discussions  above may not be applicable  depending on a
securityholder's   particular  tax  situation.  The  depositor  recommends  that
prospective  purchasers  consult their tax advisors for the tax  consequences to
them of the purchase,  ownership and  disposition of REMIC  Securities,  Grantor
Trust Securities,  Partnership  Certificates and Debt Securities,  including the
tax consequences under state, local, foreign and other tax laws and the possible
effects of changes in federal or other tax laws.

                                PENALTY AVOIDANCE

        The  summary  of tax  considerations  contained  herein  was  written to
support the promotion and marketing of the  securities,  and was not intended or
written  to be used,  and  cannot be used,  by a  taxpayer  for the  purpose  of
avoiding  United States federal  income tax penalties that may be imposed.  Each
taxpayer  is  encouraged  to seek  advice  based  on the  taxpayer's  particular
circumstances from an independent tax advisor.

                       STATE AND OTHER TAX CONSIDERATIONS

        In  addition  to  the  federal  income  tax  consequences  described  in
"Material  Federal  Income  Tax  Considerations,"   potential  investors  should
consider the state and local tax consequences of the acquisition, ownership, and
disposition  of the Notes or  Certificates,  as  applicable,  offered under this
prospectus.  State and local law may differ substantially from the corresponding
federal tax law,  and the  discussion  above does not  purport to  describe  any
aspect  of  the  tax  laws  of  any  state  or  other  jurisdiction.  Therefore,
prospective  investors  are  encouraged  to consult  their own tax advisors with
respect to the various state and other tax  consequences  of  investments in the
Notes and  Certificates,  as applicable,  offered under this  prospectus and the
prospectus   supplement.   In  particular,   individuals   should  consider  the
deductability of the expenses (including interest expense) of a partnership.

                              ERISA CONSIDERATIONS

GENERAL

        A fiduciary of a pension,  profit-sharing,  retirement or other employee
benefit plan subject to Title I of ERISA should consider the fiduciary standards
under the Employee  Retirement Income Security Act of 1974, as amended ("ERISA")
in the context of the plan's  particular  circumstances  before  authorizing  an
investment  of a portion of such plan's assets in the  Securities.  Accordingly,
pursuant to Section 404 of ERISA,  such  fiduciary  should  consider among other
factors  (i)  whether  the  investment  is for  the  exclusive  benefit  of plan
participants and their beneficiaries;  (ii) whether the investment satisfies the
applicable  diversification  requirements;  (iii)  whether the  investment is in
accordance  with the documents  and  instruments  governing  the plan;  and (iv)
whether the  investment is prudent,  considering  the nature of the  investment.
Fiduciaries  of plans also  should  consider  ERISA's  prohibition  on  improper
delegation of control over, or responsibility for, plan assets.

        In addition,  employee  benefit plans or other  retirement  arrangements
subject to ERISA, as well as individual  retirement  accounts,  certain types of
Keogh plans not subject to ERISA but subject to Section 4975 of the Code, or any
entity  (including   insurance  company  separate  or  general  accounts)  whose
underlying  assets include plan assets by reason of such plans,  arrangements or
accounts  investing in the entity (each, a "Plan") are prohibited  from engaging
in a broad  range of  transactions  involving  Plan  assets and  persons  having
certain   specified   relationships   to  a  Plan  ("parties  in  interest"  and
"disqualified   persons").   Such   transactions   are  treated  as  "prohibited
transactions"  under  Sections  406 of  ERISA  and  excise  taxes  and/or  other
penalties are imposed upon such persons  under ERISA and/or  Section 4975 of the
Code  unless an  exemption  applies.  The  depositor,  underwriter,  each master
servicer or other servicer,  any insurer, the trustee, the indenture trustee and
certain  of their  affiliates  might be  considered  "parties  in  interest"  or
"disqualified  persons" with respect to a Plan. If so, the acquisition,  holding
or disposition of Securities by or on behalf of such Plan could be considered to
give rise to a "prohibited transaction" within the meaning of ERISA and the Code
unless a  statutory,  regulatory  or  administrative  exception  or exemption is
available.

ERISA CONSIDERATIONS RELATING TO CERTIFICATES

        PLAN ASSETS

        In 29 C.F.R  ss.2510.3-101  (the  "Plan  Asset  Regulations"),  the U.S.
Department  of Labor  ("DOL") has defined  what  constitutes  "plan  assets" for
purposes  of ERISA and  Section  4975 of the Code.  The Plan  Asset  Regulations
provide that if a Plan makes an investment in an "equity interest" in an entity,
an undivided  portion of the assets of the entity will be considered  the assets
of such Plan unless certain  exceptions set forth in such Regulations apply. The
Certificates  will be deemed an equity  interest  for purposes of the Plan Asset
Regulations,  and the depositor can give no assurance that the Certificates will
qualify for any of the exceptions under the Plan Asset Regulations. As a result,
(i) a Plan may be deemed  to have  acquired  an  interest  in the  Assets of the
issuing  entity  and not  merely  an  interest  in the  Certificates,  (ii)  the
fiduciary  investment  standards  of ERISA  could apply to such Assets and (iii)
transactions  occurring in the course of managing,  operating  and servicing the
issuing entity and its Assets might constitute prohibited transactions, unless a
statutory, regulatory or administrative exemption applies.

        PROHIBITED TRANSACTION CLASS EXEMPTION 83-1

        The DOL has issued an administrative  exemption,  Prohibited Transaction
Class Exemption 83-1 ("PTCE 83-1"),  which under certain conditions exempts from
the application of the prohibited  transaction rules of ERISA and the excise tax
provisions of Section 4975 of the Code transactions

                                      140



involving a Plan in connection  with the operation of a "mortgage  pool" and the
purchase, sale and holding of Certificates which are "mortgage pool pass-through
certificates."  A  "mortgage  pool"  is  defined  as  a  fixed  investment  pool
consisting  solely of  interest-bearing  obligations  secured by first or second
mortgages  or deeds of trust on  single-family  residential  property,  property
acquired in foreclosure and  undistributed  cash. A "mortgage pool  pass-through
certificate" is defined as a Certificate which represents a beneficial undivided
interest in a mortgage pool which  entitles the holder to pass through  payments
of principal and interest from the mortgage loans.  PTCE 83-1 requires that: (i)
the depositor and the trustee maintain a system of insurance or other protection
for the  mortgage  loans,  the property  securing  such  mortgage  loans and for
indemnifying holders of Certificates against reductions in pass-through payments
due to defaults in loan payments or property  damage in an amount at least equal
to the  greater of (x) 1% of the  aggregate  principal  balance of the  mortgage
loans or (y) 1% of the principal  balance of the largest covered pooled mortgage
loans; (ii) the trustee may not be an affiliate of the depositor;  and (iii) the
payments made to, and retained by, the depositor in connection  with the issuing
entity,  together  with all funds inuring to its benefit for  administering  the
issuing entity,  represent no more than "adequate consideration" for selling the
mortgage  loans,  plus  reasonable  compensation  for  services  provided to the
issuing entity. In addition,  PTCE 83-1 exempts the initial sale of Certificates
to a Plan with respect to which the depositor,  the insurer, the master servicer
or other servicer or the trustee is a party in interest if the Plan does not pay
more than fair market value for such  Certificates  and the rights and interests
evidenced by such  Certificates are not subordinated to the rights and interests
evidenced by other Certificates of the same pool.

        PTCE  83-1  also  exempts  from the  prohibited  transaction  rules  any
transactions  in  connection  with the  servicing  and operation of the mortgage
pool,  provided that any payments made to the master servicer in connection with
the  servicing  of the  issuing  entity  are made in  accordance  with a binding
agreement, copies of which must be made available to prospective Plan investors.
In the  case of any Plan  with  respect  to  which  the  depositor,  the  master
servicer,  the insurer or the trustee is a fiduciary,  PTCE 83-1 will only apply
if, in addition to the other  requirements:  (i) the initial  sale,  exchange or
transfer of Certificates is expressly  approved by an independent  fiduciary who
has  authority  to manage  and  control  those Plan  assets  being  invested  in
Certificates; (ii) the Plan pays no more for the Certificates than would be paid
in an  arm's-length  transaction;  (iii) no investment  management,  advisory or
underwriting  fee,  sales  commission  or  similar  compensation  is paid to the
depositor with regard to the sale,  exchange or transfer of  Certificates to the
Plan; (iv) the total value of the  Certificates  purchased by such Plan does not
exceed 25% of the amount issued and (v) at least 50% of the aggregate  amount of
Certificates is acquired by persons  independent of the depositor,  the trustee,
the master servicer and the insurer. Before purchasing Certificates, a fiduciary
of a Plan should confirm that the issuing entity is a "mortgage  pool," that the
Certificates  constitute "mortgage pool pass-through  certificates" and that the
conditions set forth in PTCE 83-1 would be satisfied.  In addition to making its
own  determination  as to the  availability of the exemptive  relief provided in
PTCE 83-1,  the Plan fiduciary  should  consider the  availability  of any other
prohibited transaction  exemptions.  The Plan fiduciary should also consider its
general fiduciary obligations under ERISA in determining whether to purchase any
Certificates on behalf of a Plan pursuant to PTCE 83-1.

        UNDERWRITER EXEMPTION

        The DOL has  granted to Deutsche  Bank  Securities  Inc.  an  individual
exemption,  Prohibited  Transaction  Exemption  94-84,  and to  Deutsche  Morgan
Grenfell/C.J.  Lawrence  Inc.,  similar  approval (FAN 97-03E),  which were both
amended by Prohibited  Transaction  Exemption  97-34 ("PTE  97-34"),  Prohibited
Transaction  Exemption  2000-58  ("PTE  2000-58")  and  Prohibited   Transaction
Exemption  2002-41 ("PTE  2002-41")  (collectively,  the  "Exemption")  which is
applicable to Certificates which meet its requirements  whenever the underwriter
or  its  affiliate  is  the  sole  underwriter,  manager  or  co-manager  of  an
underwriting  syndicate  or is the selling or  placement  agent.  The  Exemption
generally  exempts certain  transactions  from the application of certain of the

                                      141



prohibited  transaction  provisions  of  ERISA  and the Code  provided  that the
conditions set forth in the Exemption are satisfied.  These transactions include
the  servicing,  managing  and  operation of  investment  trusts  holding  fixed
(generally  non-revolving  pools)  of  enumerated  categories  of  assets  which
include:  single and multi-family  residential mortgage loans, home equity loans
or receivables  (including  cooperative  housing  loans),  manufactured  housing
loans,  guaranteed governmental mortgage pool certificates and previously issued
securities  eligible  under the Exemption and the purchase,  sale and holding of
Certificates  which represent  beneficial  ownership  interests in the assets of
such trusts.

        GENERAL CONDITIONS OF EXEMPTION

        The Exemption sets forth general  conditions which must be satisfied for
a transaction involving the purchase, sale and holding of the Certificates to be
eligible for exemptive relief thereunder. First, the acquisition of Certificates
by Plans  must be on terms  that are at least as  favorable  to the Plan as they
would be in an arm's-length  transaction  with an unrelated party.  Second,  the
Assets held by the issuing entity must be fully secured (other than  one-to-four
family residential  mortgage loans and home equity loans or receivables  backing
certain types of Certificates,  as described  below).  (Mortgage  loans,  loans,
obligations  and  receivables  will  be  collectively   referred  to  herein  as
"loans.").  Third,  unless the Certificates  are backed by fully-secured  loans,
they  may  not  be  subordinated.   Fourth,   except  as  described  below,  the
Certificates  at the time of  acquisition by the Plan must generally be rated in
one of the four highest  generic rating  categories by Standard & Poor's Ratings
Services,  a division of The  McGraw-Hill  Companies,  Inc.,  Moody's  Investors
Services, Inc. or Fitch, Inc. (each, a "Rating Agency").  Fifth, the trustee and
the  indenture  trustee  generally  cannot be  affiliates  of any  member of the
"Restricted  Group" other than any underwriter as defined in the Exemption.  The
"Restricted  Group" consists of any (i) underwriter as defined in the Exemption,
(ii) the  depositor,  (iii) the master  servicer,  (iv) each  servicer,  (v) the
insurer,  (vi) the counterparty of any "interest rate swap" (as described below)
held as an Asset of the  issuing  entity and (vii) any obligor  with  respect to
loans constituting more than 5% of the aggregate  unamortized  principal balance
of the loans held in the  issuing  entity as of the date of initial  issuance of
the Certificates.  Sixth, the sum of all payments made to, and retained by, such
underwriters   must  represent  not  more  than  reasonable   compensation   for
underwriting the Certificates; the sum of all payments made to, and retained by,
the depositor  pursuant to the  assignment  of the loans to the related  issuing
entity must represent not more than the fair market value of such loans; and the
sum of all  payments  made to, and  retained  by, the  master  servicer  and any
servicer must represent not more than reasonable  compensation for such person's
services  under the Agreement  and  reimbursement  of such  person's  reasonable
expenses in connection therewith.  Seventh, (i) the investment pool must consist
only of assets  of the type  enumerated  in the  Exemption  and which  have been
included in other investment pools; (ii)  Certificates  evidencing  interests in
such other  investment  pools  must have been  rated in one of the four  highest
generic  rating  categories by one of the Rating  Agencies for at least one year
prior to a Plan's acquisition of Certificates; and (iii) Certificates evidencing
interests in such other  investment  pools must have been purchased by investors
other  than  Plans  for at least  one year  prior  to a  Plan's  acquisition  of
Certificates.  Finally,  the investing  Plan must be an  accredited  investor as
defined in Rule 501(a)(1) of Regulation D of the Commission under the Securities
Act of 1933, as amended. If Securities are being sold under the Exemptions,  the
depositor  assumes  that only Plans  which are  accredited  investors  under the
federal securities laws will be permitted to purchase the Certificates.

        Residential  (one- to-four  family) and home equity  loans,  may be less
than  fully  secured,  provided  that the  rights  and  interests  evidenced  by
Certificates issued in such transactions are: (a) not subordinated to the rights
and  interests  evidenced by  Securities  of the same issuing  entity;  (b) such
Certificates acquired by the Plan have received a rating from a Rating Agency at
the time of such  acquisition  that is in one of the two highest  generic rating
categories;  and (c) any loan  included  in the corpus or Assets of the  issuing
entity is secured by  collateral  whose fair market

                                      142



value on the closing date of the  Designated  Transactions  is at least equal to
80% of the sum of:  (i) the  outstanding  principal  balance  due under the loan
which  is  held  by the  issuing  entity  and  (ii)  the  outstanding  principal
balance(s) of any other loan(s) of higher  priority  (whether or not held by the
issuing entity) which are secured by the same collateral.

        TYPES OF ISSUING ENTITIES

        The  Exemption  permits  the issuer to be an  owner-trust,  a REMIC or a
grantor  trust.  Owner-trusts  are  subject  to  certain  restrictions  in their
governing  documents  to ensure  that  their  Assets  may not be  reached by the
creditors of the depositor in the event of bankruptcy  or other  insolvency  and
must provide certain legal opinions.

        COVERAGE FOR CERTIFICATES NOT EXEMPTION ELIGIBLE

        In the  event  that  Certificates  do not meet the  requirements  of the
Exemption  solely because they are  Subordinate  Certificates  or fail to meet a
minimum rating requirement under the Exemption, certain Plans may be eligible to
purchase  Certificates  pursuant to Section III of Prohibited  Transaction Class
Exemption 95-60 ("PTCE 95-60") which permits  insurance company general accounts
as defined in PTCE 95-60 to purchase such  Certificates  if they  otherwise meet
all of the other requirements of the Exemption.

        PERMITTED ASSETS

        The  Amendment  permits  an  interest-rate  swap  agreement  and a yield
supplement agreement to be Assets of an issuing entity which issues Certificates
acquired  by  Plans  in an  initial  offering  or in the  secondary  market.  An
interest-rate  swap (or if purchased  by or on behalf of the issuing  entity) an
interest-rate  cap contract  (collectively,  a "Swap" or "Swap  Agreement") is a
permitted  issuing entity Asset if it: (a) is an "eligible Swap;" (b) is with an
"eligible  counterparty;"  (c) is purchased by a "qualified  plan investor;" (d)
meets certain additional specific conditions which depend on whether the Swap is
a "ratings dependent Swap" or a "non-ratings dependent Swap" and (e) permits the
issuing entity to make termination payments to the Swap counterparty (other than
currently  scheduled  payments)  solely from excess spread or amounts  otherwise
payable to the servicer or depositor.

        An "eligible Swap" is one which: (a) is denominated in U.S. dollars; (b)
pursuant to which the issuing entity pays or receives,  on or immediately  prior
to the respective  payment or distribution date for the class of Certificates to
which the Swap relates,  a fixed rate of interest or a floating rate of interest
based on a publicly  available index (E.G.,  LIBOR or the U.S. Federal Reserve's
Cost of Funds Index (COFI)),  with the issuing entity receiving such payments on
at least a  quarterly  basis and  obligated  to make  separate  payments no more
frequently than the  counterparty,  with all simultaneous  payments being netted
("Allowable  Interest  Rate");  (c) has a notional  amount  that does not exceed
either: (i) the principal balance of the class of Certificates to which the Swap
relates,  or (ii) the portion of the principal balance of such class represented
by  obligations  ("Allowable  Notional  Amount");  (d) is not  leveraged  (I.E.,
payments are based on the applicable  notional amount,  the day count fractions,
the fixed or floating rates  permitted  above,  and the  difference  between the
products  thereof,  calculated on a one-to-one  ratio and not on a multiplier of
such difference) ("Leveraged");  (e) has a final termination date that is either
the earlier of the date on which the issuer  terminates  or the related class of
Certificates  are fully repaid and (f) does not  incorporate any provision which
could cause a unilateral alteration in the interest rate requirements  described
above or the prohibition against leveraging.

        An "eligible  counterparty" means a bank or other financial  institution
which has a rating at the date of issuance of the Certificates,  which is in one
of the  three  highest  long-term  credit  rating  categories  or one of the two
highest  short-term  credit  rating  categories,  utilized  by at  least  one of

                                      143



the Rating Agencies rating the Certificates; provided that, if a counterparty is
relying  on its  short-term  rating to  establish  eligibility  hereunder,  such
counterparty  must either have a  long-term  rating in one of the three  highest
long-term  rating  categories or not have a long-term rating from the applicable
Rating Agency.

        A "qualified plan investor" is a Plan or Plans where the decision to buy
such  class of  Certificates  is made on  behalf  of the Plan by an  independent
fiduciary  qualified to understand the Swap  transaction and the effect the Swap
would have on the rating of the  Certificates and such fiduciary is either (a) a
"qualified  professional  asset manager"  ("QPAM") under Prohibited  Transaction
Class  Exemption  84-14  ("PTCE  84-14") (see  below),  (b) an  "in-house  asset
manager" under Prohibited  Transaction Class Exemption 96-23 ("PTCE 96-23") (see
below) or (c) has total assets (both Plan and non-Plan)  under  management of at
least $100 million at the time the Certificates are acquired by the Plan.

        In  "ratings   dependent   Swaps"  (where  the  rating  of  a  class  of
Certificates  is dependent on the terms and  conditions  of the Swap),  the Swap
Agreement  must  provide  that  if the  credit  rating  of the  counterparty  is
withdrawn or reduced by any Rating Agency below a level  specified by the Rating
Agency,  the servicer must,  within the period  specified  under the Pooling and
Servicing  Agreement:  (a) obtain a replacement  Swap Agreement with an eligible
counterparty which is acceptable to the Rating Agency and the terms of which are
substantially  the same as the current Swap Agreement (at which time the earlier
Swap Agreement must terminate);  or (b) cause the Swap counterparty to establish
any  collateralization  or other  arrangement  satisfactory to the Rating Agency
such that the then current rating by the Rating Agency of the  particular  class
of  Certificates  will not be  withdrawn  or reduced  (and the terms of the Swap
Agreement must  specifically  obligate the  counterparty to perform these duties
for any class of  Certificates  with a term of more than one year). In the event
that the servicer fails to meet these obligations,  Plan certificateholders must
be notified in the  immediately  following  periodic report which is provided to
certificateholders  but in no  event  later  than  the end of the  second  month
beginning  after the date of such failure.  Sixty days after the receipt of such
report,  the exemptive  relief  provided under the Exemption will  prospectively
cease  to be  applicable  to any  class  of  Certificates  held by a Plan  which
involves such ratings dependent Swap.

        "Non-ratings   dependent   Swaps"   (those   where  the  rating  of  the
Certificates  does not  depend  on the  terms  and  conditions  of the Swap) are
subject to the following conditions. If the credit rating of the counterparty is
withdrawn or reduced below the lowest level permitted  above, the servicer will,
within a specified period after such rating withdrawal or reduction:  (a) obtain
a replacement Swap Agreement with an eligible  counterparty,  the terms of which
are  substantially  the same as the current  Swap  Agreement  (at which time the
earlier Swap  Agreement  must  terminate);  (b) cause the  counterparty  to post
collateral  with the issuing  entity in an amount equal to all payments  owed by
the counterparty if the Swap  transaction were terminated;  or (c) terminate the
Swap Agreement in accordance with its terms.

        An  "eligible  yield  supplement  agreement"  is  any  yield  supplement
agreement or similar arrangement (or if purchased by or on behalf of the issuing
entity) an interest rate cap contract to supplement the interest rates otherwise
payable on obligations held by the issuing entity ("EYS Agreement").  If the EYS
Agreement has a notional  principal amount and/or is written on an International
Swaps and Derivatives Association,  Inc. (ISDA) form, the EYS Agreement may only
be held as an Asset of the issuing entity if it meets the following  conditions:
(a) it is denominated in U.S. dollars;  (b) it pays an Allowable  Interest Rate;
(c) it is not  Leveraged;  (d) it does not  allow any of these  three  preceding
requirements to be unilaterally  altered without the consent of the trustee; (e)
it is entered into between the issuing entity and an eligible  counterparty  and
(f) it has an Allowable Notional Amount.

                                      144



        PRE-FUNDING ACCOUNTS

        If  Certificates  issued  in  transactions  using  pre-funding  accounts
whereby a portion of the loans backing the  Certificates  are transferred to the
issuing  entity  within a specified  period  following  the  closing  date ("DOL
Pre-Funding  Period")  (see below)  instead of requiring  that all such loans be
either identified or transferred on or before the closing date. Exemptive relief
is available provided that the following conditions are met. First, the ratio of
the amount allocated to the Pre-Funding Account to the total principal amount of
the Certificates being offered ("Pre-Funding Limit") must not exceed twenty-five
percent (25%). Second, all loans transferred after the closing date (referred to
here as  "additional  loans")  must  meet  the same  terms  and  conditions  for
eligibility as the original loans used to create the issuing entity, which terms
and conditions have been approved by the Rating Agency.  Third,  the transfer of
such additional  loans to the issuing entity during the DOL  Pre-Funding  Period
must not result in the  Certificates  receiving a lower  credit  rating from the
Rating Agency upon  termination  of the DOL  Pre-Funding  Period than the rating
that was obtained at the time of the initial issuance of the Certificates by the
issuing  entity.  Fourth,  solely  as a result  of the use of  pre-funding,  the
weighted average annual  percentage  interest rate (the "average interest rate")
for all of the loans in the  issuing  entity  at the end of the DOL  Pre-Funding
Period must not be more than 100 basis  points  lower than the average  interest
rate for the loans which were  transferred  to the issuing entity on the closing
date. Fifth,  either:  (i) the  characteristics  of the additional loans must be
monitored by an insurer or other credit support provider which is independent of
the depositor;  or (ii) an independent accountant retained by the depositor must
provide the depositor with a letter (with copies  provided to the Rating Agency,
the underwriter and the trustee) stating whether or not the  characteristics  of
the additional loans conform to the characteristics described in the Prospectus,
Prospectus  Supplement,  Private  Placement  Memorandum  ("Offering  Documents")
and/or the Agreement.  In preparing such letter, the independent accountant must
use the same type of  procedures  as were  applicable  to the loans  which  were
transferred as of the closing date.  Sixth, the DOL Pre-Funding  Period must end
no later than three  months or 90 days after the  closing  date or  earlier,  in
certain  circumstances,  if the amount on deposit in the Pre-Funding  Account is
reduced  below the  minimum  level  specified  in the  Agreement  or an event of
default  occurs  under  the  Agreement.  Seventh,  amounts  transferred  to  any
Pre-Funding Account and/or Capitalized  Interest Account used in connection with
the pre-funding  may be invested only in investments  which are permitted by the
Rating Agency and (i) are direct obligations of, or obligations fully guaranteed
as to timely  payment of principal  and  interest  by, the United  States or any
agency or instrumentality  thereof (provided that such obligations are backed by
the full faith and credit of the United States); or (ii) have been rated (or the
obligor has been rated) in one of the three highest generic rating categories by
the  Rating  Agency  ("Acceptable  Investments").   Eighth,  certain  disclosure
requirements must be met.

        REVOLVING POOL FEATURES

        The Exemption only covers  Certificates backed by "fixed" pools of loans
which require that all the loans must be  transferred  to the issuing  entity or
identified at closing (or  transferred  within the DOL  Pre-Funding  Period,  if
pre-funding  meeting  the  conditions  described  above is  used).  Accordingly,
Certificates  issued by issuing entities which feature revolving pools of Assets
will not be eligible  for a purchase  by Plans.  However,  Securities  which are
Notes backed by revolving  pools of Assets may be eligible for purchase by Plans
pursuant to certain other  prohibited  transaction  exemptions.  See  discussion
below in "ERISA Considerations Relating to Notes."

        LIMITATIONS ON SCOPE OF THE EXEMPTION

        If the general conditions of the Exemption are satisfied,  the Exemption
may provide an exemption from the restrictions  imposed by ERISA and the Code in
connection  with  the  initial   acquisition,   transfer  or  holding,  and  the
acquisition or  disposition  in the secondary  market,  of the  Certificates  by
Plans.  However, no exemption is provided from the restrictions of ERISA for the


                                      145



acquisition or holding of a Certificates  on behalf of an "Excluded Plan" by any
person who is a fiduciary  with respect to the assets of such Excluded Plan. For
those  purposes,  an  Excluded  Plan is a Plan  sponsored  by any  member of the
Restricted  Group.  Exemptive  relief may also be provided for the  acquisition,
holding  and  disposition  of  Certificates  by  Plans if the  fiduciary  or its
affiliate  is the obligor with respect to 5% or less of the fair market value of
the Loans in the issuing  entity  provided that: (i) the Plan is not an Excluded
Plan, (ii) each Plan's  investment in each class of Certificates does not exceed
25% of the  outstanding  Certificates  in the  class,  (iii)  after  the  Plan's
acquisition of the  Certificates,  no more than 25% of the assets over which the
fiduciary  has  investment  authority  are invested in  Certificates  of a trust
containing  assets which are sold or serviced by the same entity and (iv) in the
case of initial issuance (but not secondary market  transactions),  at least 50%
of each class of Certificates and at least 50% of the aggregate interests in the
issuing entity are acquired by persons independent of the Restricted Group.

ERISA CONSIDERATIONS RELATING TO NOTES

        Under the Plan Asset Regulations, the Assets of the issuing entity would
be treated as "plan  assets"  of a Plan for the  purposes  of ERISA and the Code
only if the Plan acquires an "equity interest" in the issuing entity and none of
the exceptions contained in the Plan Asset Regulations is applicable.  An equity
interest is defined under the Plan Asset  Regulations  as an interest other than
an instrument  which is treated as indebtedness  under  applicable local law and
which has no substantial equity features. Assuming that the Notes are treated as
indebtedness  without substantial equity features for purposes of the Plan Asset
Regulations,  then such Notes will be eligible for  purchase by Plans.  However,
without regard to whether the Notes are treated as an "equity interest" for such
purposes, the acquisition or holding of Notes by or on behalf of a Plan could be
considered to give rise to a prohibited transaction if the issuing entity or any
of its affiliates is or becomes a party in interest or disqualified  person with
respect to such Plan,  or in the event that a Note is purchased in the secondary
market and such  purchase  constitutes  a sale or exchange  between a Plan and a
party in interest or disqualified person with respect to such Plan. There can be
no assurance  that the issuing  entity or any of its  affiliates  will not be or
become a party in interest or a disqualified  person with respect to a Plan that
acquires Notes.

        The  Amendment  to the  Exemption  permits  issuing  entities  which are
grantor trusts,  owner-trusts or REMICs to issue Notes, as well as Certificates,
provided a legal opinion is received to the effect that the  noteholders  have a
perfected security interest in the issuing entity's Assets. The exemptive relief
provided  under the Exemption  for any  prohibited  transactions  which could be
caused as a result of the  operation,  management  or  servicing  of the issuing
entity  and its  Assets  would not be  necessary  with  respect to Notes with no
substantial  equity  features  which are issued as  obligations  of the  issuing
entity.  However, with respect to the acquisition,  holding or transfer of Notes
between a Plan and a party in interest,  the Exemption would provide  prohibited
transaction exemptive relief, provided that the same conditions of the Exemption
described above relating to Certificates  are met with respect to the Notes. The
same   limitations  of  such  exemptive   relief  relating  to  acquisitions  of
Certificates  by  fiduciaries  with  respect  to  Excluded  Plans  would also be
applicable  to the Notes as  described  herein in  "Limitations  on Scope of the
Exemption."

        In the event that the Exemption is not  applicable to the Notes,  one or
more  other  prohibited  transactions  exemptions  may  be  available  to  Plans
purchasing  or  transferring  the Notes  depending in part upon the type of Plan
fiduciary making the decision to acquire the Notes and the  circumstances  under
which such decision is made. These exemptions  include,  but are not limited to,
Prohibited  Transaction Class Exemption 90-1 (regarding investments by insurance
company pooled separate accounts),  Prohibited Transaction Class Exemption 91-38
(regarding  investments  by  bank  collective  investments  funds),  PTCE  84-14
(regarding  transactions  effected by "qualified  professional asset managers"),
PTCE 95-60  (regarding  investments by insurance  company general  accounts) and
PTCE 96-23  (regarding  transactions  effected  by  "in-house  asset  managers")
(collectively, the "Investor-Based Exemptions"). However, even if the conditions
specified in these

                                      146



Investor-Based  Exemptions are met, the scope of the relief  provided under such
Exemptions  might or might  not  cover  all acts  which  might be  construed  as
prohibited transactions.

        EACH   PROSPECTUS   SUPPLEMENT  WILL  CONTAIN   INFORMATION   CONCERNING
CONSIDERATIONS RELATING TO ERISA AND THE CODE THAT ARE APPLICABLE TO THE RELATED
SECURITIES.   BEFORE  PURCHASING  SECURITIES  IN  RELIANCE  ON  PTCE  83-1,  THE
EXEMPTION, THE INVESTOR-BASED  EXEMPTIONS OR ANY OTHER EXEMPTION, A FIDUCIARY OF
A PLAN SHOULD ITSELF CONFIRM THAT REQUIREMENTS SET FORTH IN SUCH EXEMPTION WOULD
BE SATISFIED.

        ANY PLAN  INVESTOR  WHO  PROPOSES  TO USE "PLAN  ASSETS"  OF ANY PLAN TO
PURCHASE  SECURITIES  OF ANY SERIES OR CLASS IS  ENCOURAGED  TO CONSULT WITH ITS
COUNSEL WITH RESPECT TO THE POTENTIAL  CONSEQUENCES UNDER ERISA AND SECTION 4975
OF THE CODE OF THE ACQUISITION AND OWNERSHIP OF SUCH SECURITIES.

        Governmental  plans and church plans as defined in ERISA are not subject
to ERISA or Code Section  4975,  although  they may elect to be qualified  under
Section  401(a) of the Code and exempt from taxation under Section 501(a) of the
Code and would then be subject to the prohibited  transaction rules set forth in
Section  503 of the Code.  In  addition,  governmental  plans may be  subject to
federal,  state and local  laws which are to a  material  extent  similar to the
provisions  of ERISA or a Code Section 4975  ("Similar  Law").  A fiduciary of a
governmental  plan should make its own  determination  as to the propriety of an
investment  in  Securities  under  applicable   fiduciary  or  other  investment
standards and the need for the  availability  of any exemptive  relief under any
Similar Law.

                                LEGAL INVESTMENT

        The  prospectus  supplement  will specify  which classes of the Notes or
Certificates,   as  applicable,   if  any,  will  constitute  "mortgage  related
securities"  for purposes of the Secondary  Mortgage  Market  Enhancement Act of
1984, as amended ("SMMEA").  Generally, only classes of Offered Notes or Offered
Certificates, as applicable, that (1) are rated in one of the two highest rating
categories  by one or  more  rating  agencies  and  (2)  are  part  of a  series
representing  interests  in,  or  secured  by, an  issuing  entity'  trust  fund
consisting of loans  secured by first liens on real  property and  originated by
particular types of originators  specified in SMMEA,  will be "mortgage  related
securities" for purposes of SMMEA.

        Those classes of Offered Notes or Offered  Certificates,  as applicable,
qualifying as "mortgage  related  securities" will constitute legal  investments
for persons, trusts, corporations,  partnerships,  associations, business trusts
and business  entities  (including,  but not limited to, state chartered savings
banks,  commercial banks, savings and loan associations and insurance companies,
as well as trustees and state government  employee  retirement  systems) created
pursuant  to or  existing  under the laws of the  United  States or of any state
(including   the  District  of  Columbia  and  Puerto  Rico)  whose   authorized
investments  are  subject to state  regulation  to the same extent  that,  under
applicable law, obligations issued by or guaranteed as to principal and interest
by the United  States or any  agency or  instrumentality  of the  United  States
constitute legal investments for those entities.  Pursuant to SMMEA, a number of
states enacted  legislation,  on or before the October 3, 1991 cut-off for those
enactments,  limiting  to  varying  extents  the  ability of some  entities  (in
particular,  insurance  companies)  to invest  in  mortgage  related  securities
secured  by  liens  on  residential,   or  mixed   residential  and  commercial,
properties,  in most cases by requiring  the  affected  investors to rely solely
upon existing state law, and not SMMEA.

        SMMEA also amended the legal investment authority of federally-chartered
depository  institutions as follows:  federal savings and loan  associations and
federal savings banks may invest in, sell or otherwise deal in "mortgage related
securities"  without limitation as to the percentage

                                      147



of their assets represented  thereby,  federal credit unions may invest in these
securities,  and national  banks may  purchase  these  securities  for their own
account  without regard to the  limitations  generally  applicable to investment
securities  set  forth in 12 U.S.C.  ss.24  (Seventh),  subject  in each case to
regulations that the applicable federal regulatory  authority may prescribe.  In
this  connection,  the Office of the Comptroller of the Currency (the "OCC") has
amended 12 C.F.R.  Part 1 to authorize  national  banks to purchase and sell for
their own account,  without  limitation as to a percentage of the bank's capital
and surplus (but subject to compliance with general standards concerning "safety
and soundness" and retention of credit  information in 12 C.F.R.  ss.1.5),  some
"Type  IV  securities,"   defined  in  12  C.F.R.   ss.1.2(l)  to  include  some
"residential   mortgage  related   securities."  As  so  defined,   "residential
mortgage-related  security" means, in relevant part, "mortgage related security"
within the meaning of SMMEA. The National Credit Union  Administration  ("NCUA")
has adopted rules,  codified at 12 C.F.R.  Part 703, which permit federal credit
unions  to  invest  in  "mortgage   related   securities"   under  some  limited
circumstances,   other  than  stripped  mortgage  related  securities,  residual
interests  in mortgage  related  securities,  and  commercial  mortgage  related
securities,  unless the credit union has obtained written approval from the NCUA
to  participate  in  the  "investment  pilot  program"  described  in 12  C.F.R.
ss.703.140.  Thrift  institutions  that are subject to the  jurisdiction  of the
Office of  Thrift  Supervision  (the  "OTS")  should  consider  the OTS'  Thrift
Bulletin 13a (December 1, 1998),  "Management of Interest Rate Risk,  Investment
Securities,  and Derivatives Activities," before investing in any of the Offered
Notes or Offered Certificates, as applicable.

        All   depository   institutions   considering   an   investment  in  the
Certificates  should  review the  "Supervisory  Policy  Statement on  Investment
Securities and End-User Derivatives Activities" (the "1998 Policy Statement") of
the Federal Financial Institutions Examination Council ("FFIEC"), which has been
adopted by the Board of Governors  of the Federal  Reserve  System,  the Federal
Deposit Insurance Corporation,  the OCC and the OTS, effective May 26, 1998, and
by the NCUA,  effective  October 1, 1998.  The 1998 Policy  Statement sets forth
general  guidelines which depository  institutions must follow in managing risks
(including  market,  credit,  liquidity,  operational  (transaction),  and legal
risks) applicable to all securities (including mortgage pass-through  securities
and mortgage-derivative products) used for investment purposes.

        If  specified in the  prospectus  supplement,  other  classes of Offered
Notes  or  Offered  Certificates,  as  applicable,   offered  pursuant  to  this
prospectus will not constitute  "mortgage  related  securities" under SMMEA. The
appropriate  characterization  of those classes  under various legal  investment
restrictions, and thus the ability of investors subject to these restrictions to
purchase  these Offered Notes or Offered  Certificates,  as  applicable,  may be
subject to significant interpretive uncertainties.

        Institutions  whose  investment  activities are subject to regulation by
federal or state  authorities  should  review  rules,  policies  and  guidelines
adopted from time to time by those  authorities  before  purchasing  any Offered
Notes or Offered Certificates,  as applicable, as some classes or subclasses may
be deemed unsuitable  investments,  or may otherwise be restricted,  under those
rules, policies or guidelines (in some instances irrespective of SMMEA).

        The foregoing  does not take into  consideration  the  applicability  of
statutes,  rules,  regulations,   orders,  guidelines  or  agreements  generally
governing investments made by a particular investor,  including, but not limited
to, "prudent investor" provisions,  percentage-of-assets  limits provisions that
may  restrict  or  prohibit  investment  in  securities  that are not  "interest
bearing" or "income  paying,"  and with  regard to any Offered  Notes or Offered
Certificates,  as applicable,  issued in book-entry  form,  provisions  that may
restrict or prohibit  investments  in  securities  that are issued in book-entry
form.

        Except as to the  status of some  classes  of  Offered  Notes or Offered
Certificates, as applicable, as "mortgage related securities," no representation
is made as to the  proper

                                      148



characterization  of the Offered Notes or Offered  Certificates,  as applicable,
for legal investment, financial institution regulatory, or other purposes, or as
to the ability of particular  investors to purchase any Offered Notes or Offered
Certificates, as applicable, under applicable legal investment restrictions. The
uncertainties   described  above  (and  any  unfavorable  future  determinations
concerning legal investment or financial institution regulatory  characteristics
of the Offered  Notes or Offered  Certificates,  as  applicable)  may  adversely
affect  the  liquidity  of  the  Offered  Notes  or  Offered  Certificates,   as
applicable.

        Accordingly,  all investors whose  investment  activities are subject to
legal investment laws and regulations, regulatory capital requirements or review
by  regulatory  authorities  are  encouraged  to  consult  with  their own legal
advisors in determining  whether and to what extent the Offered Notes or Offered
Certificates,  as applicable, of any class constitute legal investments for them
or are subject to investment, capital or other restrictions, and, if applicable,
whether SMMEA has been overridden in any jurisdiction relevant to that investor.

                             METHODS OF DISTRIBUTION

        The Notes or Certificates, as applicable, offered by this prospectus and
by  the  supplements  to  this  prospectus  will  be  offered  in  series.   The
distribution of the Notes or Certificates,  as applicable,  may be effected from
time to time in one or more transactions,  including negotiated transactions, at
a fixed public  offering price or at varying prices to be determined at the time
of sale or at the time of commitment  therefor.  If specified in the  prospectus
supplement, the Notes or Certificates,  as applicable,  will be distributed in a
firm  commitment  underwriting,  subject  to the  terms  and  conditions  of the
underwriting  agreement,  by Deutsche Bank  Securities  Inc.  ("DBS")  acting as
underwriter  with  other  underwriters,   if  any,  named  in  the  underwriting
agreement.  In that event,  the prospectus  supplement may also specify that the
underwriters  will not be  obligated  to pay for any Notes or  Certificates,  as
applicable, agreed to be purchased by purchasers pursuant to purchase agreements
acceptable  to the  depositor.  In  connection  with  the  sale of the  Notes or
Certificates,  as applicable,  underwriters  may receive  compensation  from the
depositor or from purchasers of the Notes or Certificates, as applicable, in the
form of discounts,  concessions or commissions.  The prospectus  supplement will
describe any compensation paid by the depositor.

        As to  any  offering  of  securities,  in  additions  to the  method  of
distribution as described in the prospectus supplement and this base prospectus,
the distribution of any class of the offered  securities may be effected through
one or more resecuritization transactions, in accordance with Rule 190(b).

        Alternatively,  the prospectus  supplement may specify that the Notes or
Certificates,  as  applicable,  will be distributed by DBS acting as agent or in
some cases as principal  with respect to Notes or  Certificates,  as applicable,
that it has previously purchased or agreed to purchase.  If DBS acts as agent in
the sale of Notes or  Certificates,  as  applicable,  DBS will receive a selling
commission for each series of Notes or Certificates, as applicable, depending on
market  conditions,  expressed as a percentage of the total principal balance of
the related mortgage loans as of the Cut-off Date. The exact percentage for each
series  of  Notes or  Certificates,  as  applicable,  will be  disclosed  in the
prospectus  supplement.  To the  extent  that DBS  elects to  purchase  Notes or
Certificates,  as  applicable,  as principal,  DBS may realize losses or profits
based upon the difference  between its purchase  price and the sales price.  The
prospectus  supplement  for any series  offered other than through  underwriters
will  contain  information  regarding  the  nature  of  that  offering  and  any
agreements to be entered into between the  depositor and  purchasers of Notes or
Certificates, as applicable, of that series.

        The depositor will indemnify DBS and any underwriters against particular
civil  liabilities,  including  liabilities under the Securities Act of 1933, or
will contribute to payments DBS and any  underwriters may be required to make in
respect of these civil liabilities.

                                      149



        In the ordinary course of business,  DBS and the depositor may engage in
various securities and financing  transactions,  including repurchase agreements
to provide interim financing of the depositor's  mortgage loans pending the sale
of those  mortgage  loans or interests in those  mortgage  loans,  including the
Notes or Certificates,  as applicable.  DBS performs management services for the
depositor.

        The depositor anticipates that the Notes or Certificates, as applicable,
will be sold  primarily  to  institutional  investors.  Purchasers  of  Notes or
Certificates, as applicable,  including dealers, may, depending on the facts and
circumstances  of those  purchases,  be deemed to be  "underwriters"  within the
meaning of the Securities  Act of 1933 in connection  with reoffers and sales by
them of Notes or Certificates,  as applicable  Securityholders are encouraged to
consult with their legal  advisors in this regard  before any reoffer or sale of
Notes or Certificates, as applicable.

        As to each series of Notes or  Certificates,  as applicable,  only those
classes rated in one of the four highest rating  categories by any rating agency
will be  offered by this  prospectus.  Any lower  rated or unrated  class may be
initially  retained by the  depositor,  and may be sold by the  depositor at any
time to one or more institutional investors.

                             ADDITIONAL INFORMATION

        A new  issuing  entity  will be  formed  for  each  series  of  Notes or
Certificates,  as applicable,  and no issuing entity will engage in any business
activities or have any assets or obligations  before the issuance of the related
series  of  Notes  or  Certificates,  as  applicable.   Accordingly,   financial
statements  for an  issuing  entity  will  generally  not be  included  in  this
prospectus or in the prospectus supplement.

                                     RATING

        As a condition to the issuance of any class of Offered  Notes or Offered
Certificates, as applicable, they must not be rated lower than investment grade;
that is, they must be rated in one of the four highest rating  categories,  by a
rating agency.

        Ratings on mortgage pass-through  certificates and mortgage-backed notes
address the likelihood of receipt by securityholders of all distributions on the
underlying  mortgage  loans.  These ratings  address the  structural,  legal and
issuer-related aspects associated with the Notes or Certificates, as applicable,
the nature of the underlying assets and the credit quality of the guarantor,  if
any. Ratings on mortgage  pass-through  certificates,  mortgage-backed notes and
other asset backed  securities do not represent any assessment of the likelihood
of principal  prepayments  by  borrowers  or of the degree by which  prepayments
might differ from those  originally  anticipated.  As a result,  securityholders
might  suffer a lower than  anticipated  yield,  and,  in  addition,  holders of
stripped  interest  certificates  in extreme  cases  might fail to recoup  their
initial investments.

        A  security  rating  is  not a  recommendation  to  buy,  sell  or  hold
securities  and may be  subject to  revision  or  withdrawal  at any time by the
assigning  rating  organization.   Each  security  rating  should  be  evaluated
independently of any other security rating.
