             IMPORTANT NOTICE REGARDING THIS FREE WRITING PROSPECTUS

The depositor has filed a registration  statement  (including a prospectus) with
the SEC for the offering to which this communication relates. Before you invest,
you  should  read  the  prospectus  in that  registration  statement  and  other
documents the  depositor  has filed with the SEC for more  complete  information
about the depositor and this offering.  You may get these  documents for free by
visiting EDGAR on the SEC Web site at www.sec.gov. Alternatively, the depositor,
any underwriter or any dealer participating in the offering will arrange to send
you the prospectus if you request it by calling  toll-free  1-800-294-1322 or if
you e-mail a request to dg.prospectus_distribution@bofasecurities.com.

The asset-backed securities referred to in these materials,  and the asset pools
backing them, are subject to modification or revision (including the possibility
that one or more classes of securities  may be split,  combined or eliminated at
any time  prior to  issuance  or  availability  of a final  prospectus)  and are
offered on a "when, as and if issued" basis.  You understand  that, when you are
considering the purchase of these securities,  a contract of sale will come into
being no sooner than the date on which the relevant class has been priced and we
have confirmed the allocation of securities to be made to you; any  "indications
of interest"  expressed by you, and any "soft circles" generated by us, will not
create binding contractual obligations for you or us.

Because the  asset-backed  securities  are being  offered on a "when,  as and if
issued"  basis,  any such contract  will  terminate,  by its terms,  without any
further obligation or liability between us, if the securities themselves, or the
particular  class to which the  contract  relates,  are not issued.  Because the
asset-backed  securities  are  subject to  modification  or  revision,  any such
contract also is conditioned upon the understanding that no material change will
occur with  respect to the  relevant  class of  securities  prior to the closing
date. If a material  change does occur with respect to such class,  our contract
will  terminate,  by its terms,  without any  further  obligation  or  liability
between us (the "Automatic Termination"). If an Automatic Termination occurs, we
will provide you with revised offering materials  reflecting the material change
and give you an opportunity to purchase such class. To indicate your interest in
purchasing  the class,  you must  communicate  to us your desire to do so within
such  timeframe  as may be  designated  in  connection  with your receipt of the
revised offering materials.

The  information  contained  in these  materials  may be  based  on  assumptions
regarding  market  conditions  and  other  matters  as  reflected  herein.   The
underwriter  make  no  representation   regarding  the  reasonableness  of  such
assumptions  or the  likelihood  that any such  assumptions  will  coincide with
actual market  conditions or events,  and these  materials  should not be relied
upon for such purposes. The underwriter and its affiliates, officers, directors,
partners  and  employees,  including  persons  involved  in the  preparation  or
issuance  of  these  materials,  may,  from  time to  time,  have  long or short
positions in, and buy and sell, the securities  mentioned  herein or derivatives
thereof (including options). Information in these materials is current as of the
date appearing on the material only.  Information in these  materials  regarding
any securities discussed herein supersedes all prior information  regarding such
securities.  These  materials are not to be construed as an offer to sell or the
solicitation of any offer to buy any security in any jurisdiction  where such an
offer or solicitation would be illegal.

     IMPORTANT NOTICE RELATING TO AUTOMATICALLY GENERATED EMAIL DISCLAIMERS

Any  disclaimers  or other  notices that may appear below this  document are not

The Issuing Entity Will Issue -

o     Six classes of senior certificates.

o     Nine  classes  of  subordinated  Class M  Certificates  all of  which  are
      subordinate   to,  and  provide   credit   enhancement   for,  the  senior
      certificates.  Each class of Class M Certificates is also  subordinated to
      and provides credit enhancement for each class of Class M Certificates, if
      any, with a lower number.

o     One class of subordinated  Class B Certificates  which are subordinate to,
      and provide credit enhancement for, the senior  certificates and the Class
      M Certificates.

o     The Class CE, Class P, Class R and Class R-X Certificates.

The classes of offered certificates are listed and their sizes and basic payment
characteristics  are described under the heading  "Offered  Certificates" in the

The Assets of the Issuing Entity Will Include -

o     Three loan groups of first and second lien residential mortgage loans. The
      mortgage loans will consist of conventional fixed-rate and adjustable-rate
      sub-prime mortgage loans.

Credit Enhancement Will Consist of -

o     Excess Interest - Certain excess interest received from the mortgage loans
      will be used to cover losses.

o     Overcollateralization  - As of the cut-off  date,  the assets of the trust
      will exceed the aggregate principal balance of the certificates, resulting
      in  overcollateralization.  Certain  excess  interest  received  from  the
      mortgage  loans will also be  applied  as  payments  of  principal  on the
      certificates to maintain a required level of overcollateralization.

o     Subordination - Each class of subordinated  certificates is subordinate to
      the senior certificates and to those classes of subordinated  certificates
      higher in order of payment priority.

o     Cross-Collateralization  - Under  certain  circumstances,  payments on the
      mortgage loans in one loan group may be used to make certain distributions
      to holders of senior certificates relating to the other loan groups.

Interest Rate Support Will Consist of -

o     Interest  Rate Swap  Agreement - Net swap  payments  received by the trust
      pursuant to an interest rate swap agreement with Bank of America, National
      Association,  as swap provider, will be available to make distributions on
      the related certificates.

              IMPORTANT NOTICE ABOUT INFORMATION PRESENTED IN THIS
             FREE WRITING PROSPECTUS AND THE ACCOMPANYING PROSPECTUS

      The depositor  describes the  certificates in two separate  documents that
progressively provide more detail:

   o  the accompanying prospectus,  which provides general information,  some of
      which may not apply to your certificates, and

   o  this  free  writing  prospectus,   which  incorporates  and  includes  the
      appendices, and describes the specific terms of your certificates.

      Cross-references  are  included in this free  writing  prospectus  and the
accompanying  prospectus  to  captions  in these  materials  where  you can find
further  related  discussions.  The foregoing table of contents and the table of
contents included in the accompanying  prospectus  provide the location of these
captions.

      You can find a listing of the pages where  capitalized  terms used in this
free writing  prospectus and the  accompanying  prospectus are defined under the
caption "Index of Free Writing Prospectus Definitions" beginning on page S-93 in
this document and under the caption "Index of Prospectus  Definitions" beginning
on page 132 in the accompanying  prospectus.  Any capitalized terms used but not

accompanying prospectus.

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

      This free  writing  prospectus  and the  accompanying  prospectus  contain
forward-looking   statements   relating  to  future   economic   performance  or
projections and other financial items. Such forward-looking statements, together
with related  qualifying  language and  assumptions,  are found in the material,
including  each of the  tables,  set forth  under  "Risk  Factors"  and  "Yield,
Prepayment and Maturity  Considerations" and in the appendices.  Forward-looking
statements  are also found  elsewhere  in this free writing  prospectus  and the
accompanying  prospectus,  and may be identified by, among other things, the use
of   forward-looking   words  such  as  "expects,"   "intends,"   "anticipates,"
"estimates,"  "believes,"  "may" or other  comparable  words.  These  statements
involve known and unknown risks,  uncertainties and other important factors that
could cause the actual  results or performance  to differ  materially  from such
forward-looking  statements.   Those  risks,  uncertainties  and  other  factors
include,  among others,  general economic and business conditions,  competition,
changes in political, social and economic conditions, regulatory initiatives and
compliance with government  regulations,  customer  preference and various other
matters, many of which are beyond the depositor's control. These forward-looking
statements  speak  only as of the  date of this  free  writing  prospectus.  The
depositor  expressly disclaims any obligation or undertaking to update or revise
forward-looking statements to reflect any change in the depositor's expectations
or  any   change  in  events,   conditions   or   circumstances   on  which  any
forward-looking statement is based.

(1)   Approximate.  The initial certificate balances of the offered certificates
      may vary by a total of plus or minus 5%.

(2)   See "Description of the Certificates--Categories of Classes of Securities"
      in the prospectus for a description of these  principal and interest types
      and  see  "Description  of  the   Certificates--Interest   Distributions,"
      "--Principal  Distributions"  and  "--Allocation  of  Losses" in this free
      writing prospectus for a description of the effects of subordination.

(3)   The final scheduled  distribution date represents the distribution date in
      the month  following the latest  maturity date of any mortgage loan in the
      mortgage pool. The actual final payment on your  certificates  could occur
      earlier or later than the final scheduled distribution date.

(4)   The offered  certificates  will not be issued unless they receive at least
      the ratings set forth in this table.  See  "Ratings"  in this free writing
      prospectus.

(5)   Interest will accrue on these  certificates  during each interest  accrual
      period at a per annum rate equal to the least of (i) the sum of  one-month
      LIBOR plus the margin set forth in the table  below,  (ii) the  applicable
      maximum  rate cap and  (iii) the  applicable  group cap or the pool cap as
      described  under  "Description of the  Certificates--Certificate  Interest
      Rates" in this free  writing  prospectus.  During  each  interest  accrual
      period relating to the distribution  dates after the optional  termination
      date, the margins will increase to margins set forth in the table below if
      the  optional  termination  right  is  not  exercised.  Interest  will  be
      calculated  based on the  methodology in the table below.  One-month LIBOR
      for the initial interest accrual period will be [___]%.

The Transaction Parties

Option One Mortgage Corporation originated or acquired all of the mortgage loans
and currently services all of the mortgage loans. Prior to the closing date, the
sponsor   purchased  all  of  the  mortgage   loans  from  Option  One  Mortgage
Corporation. On the closing date the sponsor will sell the mortgage loans to the
depositor, who will in turn deposit them into a New York common law trust, which
is the  issuing  entity.  The trust  will be formed by a pooling  and  servicing
agreement,  dated as of the cut-off date, among the depositor,  the servicer and
the trustee. The servicer will service the mortgage loans in accordance with the
pooling and  servicing  agreement  and provide  the  information  to the trustee
necessary  for the  trustee to  calculate  distributions  and other  information
regarding the certificates.

The  transfers  of the mortgage  loans from the sponsor to the  depositor to the
issuing entity in exchange for the certificates is illustrated below:

The Mortgage Pool

On the  closing  date,  the  issuing  entity  will  acquire  a pool of fixed and
adjustable-rate  first and second lien mortgage loans,  designated herein as the
"mortgage  loans."  All of the  mortgage  loans were  originally  originated  or
acquired by Option One Mortgage  Corporation in accordance with the underwriting
guidelines  described  under  "Underwriting  Standards"  in  this  free  writing
prospectus.

For purposes of calculating  principal and interest  distributions on the senior
certificates, the mortgage loans have been divided into three groups, designated
as the "group 1 mortgage  loans," the "group 2 mortgage  loans" and the "group 3
mortgage loans." The group 1 mortgage loans consist only of those mortgage loans
with  original  principal  balances that conform to Fannie Mae  guidelines.  The
group 2 mortgage  loans  consist  only of those  mortgage  loans  with  original
principal balances that conform to Freddie Mac guidelines.  The group 3 mortgage
loans consist of all other remaining  mortgage loans,  which may or may not have
original  principal  balances  conforming  to  Fannie  Mae  and/or  Freddie  Mac
guidelines.  Other than certain  cross-collateralization  payments,  the Group 1
Certificates  generally  represent  interests in the group 1 mortgage loans, the
Group 2 Certificates generally represent interests in the group 2 mortgage loans
and the  Group 3  Certificates  generally  represent  interests  in the  group 3
mortgage loans. The remaining classes of certificates represent interests in all
of the  group 1  mortgage  loans,  the  group 2  mortgage  loans and the group 3
mortgage loans.

The characteristics of the mortgage pool may change because:

      o     Before the closing date,  the depositor  may remove  mortgage  loans
            from the  mortgage  pool.  The  depositor  also may  substitute  new
            mortgage  loans for mortgage loans in the mortgage pool prior to the
            closing date.

      o     After the  certificates  are issued,  mortgage  loans may be removed
            from the trust  because  of  repurchases  by the  originator  or the
            sponsor  for  breaches  of  representations  or  failure  to deliver
            required documents.  Under certain circumstances and only during the
            two-year  period  following the closing date,  the originator or the
            sponsor may instead make substitutions for these mortgage loans.


                                      S-15


See "The Pooling and Servicing  Agreement--Assignment of Mortgage Loans" in this
free writing  prospectus for a discussion of the  circumstances  under which the
originator or the sponsor is required to  repurchase or substitute  for mortgage
loans. These removals and/or substitutions may result in changes in the mortgage
loan characteristics  shown above. These changes may affect the weighted average
lives and yields to maturity of the related offered certificates.

Additional  information  on the mortgage  pool is set forth under "The  Mortgage
Pool"  and in the  tables in  Appendix  A to this free  writing  prospectus  and
information  regarding repurchases and substitutions of the mortgage loans after
the closing date will be available on the trust's monthly  distribution  reports
on  Form  10-D.  See  "Reports  to  Certificateholders"  in  this  free  writing
prospectus.

Fees and Expenses

The  servicing  fees for the  mortgage  loans are  payable  out of the  interest
payments on the mortgage loans, prior to any payments to the trustee, the credit
risk manager or distributions to  certificateholders.  The servicing fees accrue
on the mortgage loans at the servicing fee rate or rates set forth in the tables
above.  In addition to the  servicing  fees,  the  servicer  will be entitled to
retain  as  additional  servicing  compensation  (i) all  service-related  fees,
including  assumption fees,  modification fees,  extension fees, bad check fees,
late payment  charges and  interest  paid on  principal  prepayments  during the
portion of a prepayment period occurring in the month of a distribution date, to
the extent collected from  mortgagors,  (ii) any interest or other income earned
on funds held in the  collection  account and any escrow  accounts and (iii) any
profits from the liquidation of mortgage loans.

The credit risk  manager is entitled to the credit risk manager fee payable from
the    interest     portion    of    collections     described    below    under
"--Distributions--General."  The trustee is entitled  to all  investment  income
earned on amounts on deposit in the distribution account.

The depositor,  the servicer and the trustee are entitled to indemnification and
reimbursement of certain expenses from the trust under the pooling and servicing
agreement  prior to  distributions  to  certificateholders  as  discussed in the
prospectus under the headings "Description of the Agreements--Material  Terms of
the   Pooling   and    Servicing    Agreements    and    Underlying    Servicing
Agreements--Certain  Matters  Regarding  Servicers and the Master  Servicer" and
"--Certain Matters Regarding the Trustee."

See "The Pooling and Servicing  Agreement--Compensation  and Payment of Expenses
of the  Servicer,  the Trustee and the Credit Risk Manager" in this free writing
prospectus  for more  information  about fees and expenses of the servicer,  the
trustee and the credit risk manager.

For any  distribution  date  prior to and  including  the  distribution  date in
September  2011,  the  supplemental  interest  trust will be obligated to make a
monthly  payment to the swap provider  equal to the product of (x) 5.0625%,  (y)
the notional amount (as set forth in Appendix D) for such  distribution date 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  supplemental  interest  trust will be  entitled  to  receive  from the swap
provider for any distribution  date prior to and including the distribution date
in September 2011, a floating amount equal to the product of (x) one-month LIBOR
(as determined  pursuant to the interest rate swap agreement),  (y) the notional
amount for such distribution date, 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.  Only a net
payment will be required to be made on or before each  distribution  date by the
applicable party. Any amounts payable by the supplemental  interest trust to the
swap  provider  (other than a swap  termination  payment  resulting  from a swap
provider  trigger  event)  will  reduce  the  interest  remittance  amount for a
distribution  date and, to the extent that the  interest  remittance  amount for
such distribution date is insufficient, the principal remittance amount for such
distribution date, prior to any distribution to certificateholders.

reimbursements  for advances made by the servicer,  amounts  payable to the swap
provider and payment of other  expenses and  indemnities  described in this free
writing prospectus) and principal distributions on the certificates will be made
on each  distribution  date from the  principal  portion  of  collections  (less
certain amounts payable to the swap provider) related to the related loan group,

            seventh,   to  the  Class  CE,  Class  P,  Class  R  and  Class  R-X
      Certificates,  in the  amounts  specified  in the  pooling  and  servicing
      agreement.
- --------------------------------------------------------------------------------

The Class P Certificates  will also receive any  prepayment  charges paid by the
mortgagors  during the related  prepayment  period.  The amount of interest  and
principal  distributions  on each class of  certificates is more fully described
under "Description of the Certificates--Interest Distributions" and "--Principal
Distributions" in this free writing prospectus.

Interest Distributions

On each  distribution  date, you will be entitled to receive interest accrued on
your certificate  during the related interest accrual period (less the amount of
shortfalls  allocated to your certificate due to the Servicemembers Civil Relief
Act or similar  state laws) and any  interest  which you earned  previously  but
which  you did  not  receive.  The  interest  accrual  period  for  all  offered
certificates is the period from the distribution date in the prior month (or the
closing date, in the case of the first  distribution date) through the day prior
to the current  distribution  date.  Interest will be calculated for all offered
certificates  on the basis of the actual number of days in the interest  accrual
period, based on a 360-day year.

There are certain  circumstances  which could reduce the amount of interest paid
to you. See "Description of the  Certificates--Interest  Distributions"  in this
free writing prospectus.

Principal Distributions

On each  distribution date you will receive a distribution of principal if there
are funds  available on that date for your class of  certificates.  As described
above under  "--Distributions--General,"  prior to the  stepdown  date or in the
event (i) a three-month  rolling average of loans two months or more past due or
(ii)  cumulative  realized  losses exceed  certain  thresholds  described  under
"Description   of   the   Certificates--Principal    Distributions,"   principal
distributions  will be made to the senior  certificates  until their certificate
principal  balances are reduced to zero and no principal  will be distributed on
the  subordinated  certificates or distributed as part of excess  cashflow.  You
should  review the  priority of payments  described  under  "Description  of the
Certificates--Principal Distributions" in this free writing prospectus.

Credit Enhancement

Credit  enhancement  is intended to reduce the potential risk of loss to holders
of the  certificates  as a result of  shortfalls  in  payments  received  on the
mortgage  loans.  Credit  enhancement can reduce the effect of shortfalls on all
classes,  or it can  allocate  shortfalls  so they  affect some  classes  before
others. This transaction employs the following forms of credit enhancement.  See
"Description of the Certificates" in this free writing prospectus.


                                      S-18


Monthly  Excess  Interest.  Because more  interest is expected to be paid by the
mortgagors than is necessary to pay the interest earned on the  certificates and
to pay certain  fees and expenses of the trust  (including  any net swap payment
owed to the supplemental interest trust for the benefit of the swap provider and
any swap  termination  payment owed to the  supplemental  interest trust for the
benefit of the swap provider,  other than any swap termination payment resulting
from a swap  provider  trigger  event),  it is  expected  there  will be  excess
interest   each   month.   The  excess   interest   will  be  used  to  maintain
overcollateralization,  to pay interest that was previously accrued but not paid
to the  certificates,  to  reimburse  the  certificates  for losses and  certain
shortfalls  that they  experienced  previously  and to pay certain cap carryover
amounts.

Overcollateralization.  If the  total  assets  in the  trust  exceed  the  total
certificate    principal    balance    of    the    certificates,    there    is
overcollateralization.  Overcollateralization will be available to absorb losses
on the mortgage loans before such losses affect the offered certificates and the
Class B Certificates.  On the closing date, the total initial  principal balance
of the  mortgage  loans will  exceed  the total  initial  certificate  principal
balance  of the  certificates  by  approximately  $26,932,882.  This  results in
overcollateralization  equal to approximately  2.450% of the aggregate principal
balance  of the  mortgage  loans  as of  the  cut-off  date.  If  the  level  of
overcollateralization falls below the targeted  overcollateralization amount for
a distribution date, the excess interest for that distribution date will be paid
to the offered certificates and the Class B Certificates as principal. This will
have the effect of reducing the aggregate  certificate  principal balance of the
certificates  faster than the principal  balance of the mortgage loans until the
required level of overcollateralization is reached.

Subordination.  On each  distribution  date,  classes that are lower in order of
payment  priority will not receive payments until the classes that are higher in
order of payment priority have been paid. If there are  insufficient  funds on a
distribution date to pay all classes, the subordinated classes will be the first
to forego  payment.  The chart below  summarizes  the relative  seniority of the
various  classes of  certificates  and  indicates  the  approximate  initial and
expected  post-stepdown  level of credit support provided to the various classes
of certificates. The initial credit support percentage shown below is the sum of
the  aggregate  initial  class  certificate  balance  of the class or classes of
certificates   subordinate   to  a   class   or   classes   plus   the   initial
overcollateralization  amount as a percentage of the initial aggregate principal
balance of the mortgage  loans.  The expected  credit support  percentage  after
stepdown is the sum of the expected  aggregate class certificate  balance of the
class or  classes of  certificates  subordinate  to a class or classes  plus the
targeted  overcollateralization  amount on the stepdown  date as a percentage of
the expected aggregate  principal balance of the mortgage loans as of the end of
the  related  collection  period  (after  giving  effect to  expected  principal
prepayments in the related prepayment period).

(1)   The certificate  principal balances of the senior certificates will not be
      reduced by realized losses;  however, under certain loss scenarios,  there
      will not be enough interest and principal on the mortgage loans to pay the
      senior  certificates all interest and principal  amounts to which they are
      entitled.

Application  of  Realized  Losses.  If,  on  any  distribution  date  after  the
certificate  principal  balances of the  certificates  have been  reduced by the
amount of cash paid on that date, the total certificate principal balance of the
certificates  is  greater  than the sum of the total  principal  balance  of the
mortgage  loans,   the  certificate   principal   balance  of  the  subordinated
certificates that are lowest in order of payment priority will be reduced by the
amount of such  excess.  Once the  certificate  principal  balance of a class is
reduced by realized losses  allocated to it, this balance will not be


                                      S-19


reinstated  (except  in the  case of  subsequent  recoveries).  The  certificate
principal  balances  of the  senior  certificates  will not be  reduced by these
realized losses, although these certificates may experience losses if the credit
enhancements described in this free writing prospectus are exhausted.

Cross-Collateralization. In certain circumstances payments on the mortgage loans
in one loan group may be used to make certain distributions to holders of senior
certificates relating to the other loan groups.

Interest Rate Swap Agreement

The supplemental  interest trust trustee, on behalf of the supplemental interest
trust,  will enter into an interest  rate swap  agreement  with Bank of America,
National Association,  as swap provider. Under the interest rate swap agreement,
for any  distribution  date  prior to and  including  the  distribution  date in
September 2011, the supplemental  interest trust will be obligated to make fixed
payments  to the swap  provider  equal to the  product of (x)  5.0625%,  (y) the
notional amount (as set forth in Appendix D) for such  distribution date 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.
During the same period,  the swap provider will be obligated  under the interest
rate swap agreement to make floating payments to the supplemental interest trust
prior to each  distribution date equal to the product of (x) one-month LIBOR (as
determined  pursuant to the  interest  rate swap  agreement),  (y) the  notional
amount (as set forth on the table in Appendix D) for that  distribution date 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.  To the extent  that the fixed  payment  exceeds  the  floating
payment with respect to any distribution  date,  amounts otherwise  available to
certificateholders  will be applied to pay that excess to the swap provider, and
to the extent that the floating  payment  exceeds the fixed payment with respect
to any  distribution  date,  the  swap  provider  will pay  that  excess  to the
supplemental  interest trust trustee for deposit into a segregated trust account
held by the supplemental interest trust established on the closing date.

Upon early  termination of the interest rate swap  agreement,  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
supplemental interest trust is required to make a swap termination payment, that
payment will be paid on the business day prior to the related distribution date,
and, until paid in full,  one business day prior to any subsequent  distribution
dates,   generally  prior  to  any  distribution  to   certificateholders.   See
"Description  of  the  Certificates--Interest  Rate  Swap  Agreement,  the  Swap
Provider and the Swap Account" in this free writing prospectus.

Net swap  payments and swap  termination  payments  payable by the  supplemental
interest  trust  (other than swap  termination  payments  resulting  from a swap
provider trigger event) will be deducted first from the interest collections for
a month and then from principal  collections for a month before distributions to
certificateholders  and will be  deposited  into the  swap  account  held by the
supplemental  interest trust before  payment,  on a first priority basis, to the
swap provider.

Optional Termination

The NIMS  Insurer,  if any,  will have the option to purchase  all the  mortgage
loans and any properties that the issuing entity acquired in satisfaction of any
of the  mortgage  loans,  subject to  certain  conditions  described  under "The
Pooling and  Servicing  Agreement--Optional  Termination"  in this free  writing
prospectus.  If there is no NIMS  Insurer,  the majority  holder of the Class CE
Certificates  will  have the  option.  If the  majority  holder  of the Class CE
Certificates  fails to exercise the option on the first  possible  date or is an
affiliate of the sponsor,  the servicer will have the option. This option can be
exercised on any distribution  date following the distribution date on which the
total  principal  balance of the mortgage  loans,  including the mortgage  loans
related  to REO  properties,  is 10% or less of the sum of the  total  principal
balance of the mortgage loans on the cut-off date. Any such optional termination
will be  permitted  only  pursuant to a  "qualified  liquidation"  as defined in
Section 860F of the Internal Revenue Code of 1986, as amended.  If the option is
exercised,  your  certificate will be retired earlier than it would be otherwise
and you will be entitled to the  following  amounts (to the extent that there is
enough cash to make such payments):


                                      S-20


o     the outstanding certificate principal balance of your certificate;

o     one month's interest on this balance at the related  certificate  interest
      rate;

o     any interest previously earned but not paid; and

o     any "cap carryover amount," as described in this free writing  prospectus,
      from all previous distribution dates.

See "The Pooling and  Servicing  Agreement--Optional  Termination"  in this free
writing prospectus.

Prepayment and Yield Considerations

The yields to maturity and weighted  average  lives of the offered  certificates
will  depend  upon,  among  other  things,  the  price  at  which  such  offered
certificates are purchased,  the amount and timing of principal  payments on the
applicable  mortgage loans, the allocation of available funds to various classes
of offered  certificates,  the amount and timing of mortgagor  delinquencies and
defaults on the applicable mortgage loans, the rate of liquidations and realized
losses and the  allocation  of  realized  losses to  various  classes of offered
certificates.

Federal Income Tax Consequences

Elections will be made to treat the assets of the issuing  entity,  exclusive of
the  arrangements  intended  to protect  against  basis risk for  certain of the
certificates,  the cap carryover  reserve  account,  the  supplemental  interest
trust,  the interest rate swap  agreement and the swap account and certain other
assets  specified  in the pooling  and  servicing  agreement,  as  comprised  of
multiple  real estate  mortgage  investment  conduits in a tiered  structure for
federal income tax purposes.

The offered  certificates will represent (i) regular interests in a REMIC, which
will be treated as debt  instruments  of a REMIC,  and (ii) interests in certain
cap carryover  amounts and the right to receive payments from and the obligation
to make  payments  to the  supplemental  interest  trust.  Each  interest in cap
carryover  amounts and the right to receive  payments from and the obligation to
make  payments to the  supplemental  interest  trust will be treated as notional
principal contracts for federal income tax purposes.

For  further  information  regarding  the  federal  income tax  consequences  of
investing in the offered certificates,  see "Federal Income Tax Consequences" in
this free writing prospectus and in the prospectus.

Legal Investment

You are  encouraged  to consult with counsel to see if you are  permitted to buy
the offered  certificates,  since legal  investment rules will vary depending on
the type of entity purchasing the offered  certificates,  whether that entity is
subject to regulatory  authority,  and if so, by whom. The offered  certificates
will not constitute  "mortgage related securities" for purposes of the Secondary
Mortgage Market  Enhancement Act of 1984, as amended.  See "Legal Investment" in
this free writing prospectus and in the prospectus.

ERISA Considerations

If you  are a  fiduciary  of any  employee  benefit  plan  or  other  retirement
arrangement  subject to the Employee  Retirement Income Security Act of 1974, as
amended,  or Section 4975 of the Internal Revenue Code of 1986 or any materially
similar provisions of applicable federal, state or local law, you are encouraged
to  consult  with  counsel  as to  whether  you  can  buy  or  hold  an  offered
certificate. Subject to the considerations and conditions described under "ERISA
Considerations" in this free writing prospectus, it is expected that the offered
certificates  may be  purchased  by a pension  or other  employee  benefit  plan
subject to the Employee  Retirement Income Security Act of 1974, as amended,  or
Section 4975 of the  Internal  Revenue  Code of 1986,  as amended.  Prior to the
termination of the supplemental interest trust, plans or persons using assets of
a plan may only purchase the offered certificates if the


                                      S-22


purchase  and holding of such  certificates  also meets the  requirements  of an
investor-based class exemption issued by the Department of Labor. A fiduciary of
an employee  benefit plan must  determine  that the purchase of a certificate is
consistent with its fiduciary duties under applicable law and does not result in
a prohibited  transaction  under applicable law. See "ERISA  Considerations"  in
this prospectus supplement and in the prospectus.

                                  RISK FACTORS

      The risk factors  discussed  below and under the heading "Risk Factors" in
the  prospectus  describe the  material  risks of an  investment  in the offered
certificates and should be carefully considered by all potential investors.

There are risks  involving  unpredictability  of  prepayments  and the effect of
prepayments on yields

      The rate of principal payments,  the aggregate amount of distributions and
the yields to maturity of the offered  certificates  will be related to the rate
and timing of payments of principal on the applicable  mortgage loans.  The rate
of  principal  payments  on the  mortgage  loans will in turn be affected by the
amortization  schedules  of the  mortgage  loans  and by the  rate of  principal
prepayments (including for this purpose prepayments resulting from refinancings,
liquidations of the mortgage loans due to defaults,  casualties or condemnations
and repurchases by the sponsor, the originator or the servicer).  Mortgagors may
prepay their  mortgage  loans in whole or in part at any time. We cannot predict
the rate at which  mortgagors will repay their mortgage loans. A prepayment of a
mortgage loan generally will result in a prepayment of the certificates.

   o  If you purchase  your  certificates  at a discount and principal is repaid
      more  slowly  than you  anticipate,  then your yield may be lower than you
      anticipate.

   o  If you purchase  your  certificates  at a premium and  principal is repaid
      faster  than  you  anticipate,  then  your  yield  may be  lower  than you
      anticipate.

   o  The  rate of  prepayments  on the  mortgage  loans  will be  sensitive  to
      prevailing interest rates. Generally, if prevailing interest rates decline
      significantly  below the interest rates on the fixed-rate  mortgage loans,
      those  mortgage  loans are more likely to prepay than if prevailing  rates
      remain above the interest  rates on such mortgage  loans.  Conversely,  if
      prevailing   interest  rates  rise   significantly,   the  prepayments  on
      fixed-rate mortgage loans are likely to decrease.  The prepayment behavior
      of the adjustable-rate mortgage loans and of the fixed-rate mortgage loans
      may respond to different factors,  or may respond  differently to the same
      factors.  If at the time of their first adjustment,  the interest rates on
      any of the  adjustable-rate  mortgage loans would be subject to adjustment
      to a  rate  higher  than  the  then  prevailing  mortgage  interest  rates
      available  to the  related  borrowers,  such  borrowers  may prepay  their
      adjustable-rate  mortgage loans.  Adjustable-rate  mortgage loans may also
      suffer  an  increase  in  defaults  and   liquidations   following  upward
      adjustments of their interest  rates,  especially  following their initial
      adjustments.

   o  The rate of prepayments on pools of mortgage loans may vary  significantly
      over time and may be influenced by a variety of economic,  geographic  and
      other  factors,  including  changes  in  mortgagors'  housing  needs,  job
      transfers,   unemployment,   mortgagors'   net  equity  in  the  mortgaged
      properties and servicing decisions.

   o  As of the  cut-off  date,  certain  of the  mortgage  loans  required  the
      mortgagor  to pay a charge if the  mortgagor  prepays  the  mortgage  loan
      during periods ranging, in substantially all cases, from one year to three
      years after the mortgage loan was originated. See the mortgage loan tables
      under "Summary of Free Writing Prospectus" in this free writing prospectus
      for the  percentages  of the  mortgage  loans in each  loan  group and the
      mortgage  pool that require the  mortgagor to pay a prepayment  charge.  A
      prepayment  charge may  discourage a mortgagor from prepaying the mortgage
      loan  during  the  applicable  period.  Such  prepayment  charges  will be
      distributed to holders of the Class P  Certificates  and not to holders of
      the offered  certificates.  The  servicer is entitled to waive  prepayment
      charges,  subject to certain conditions  specified in the prospectus under
      "Description  of  the  Agreements--Material   Terms  of  the  Pooling  and
      Servicing Agreements and Underlying Servicing  Agreements--Collection  and
      Other Servicing Procedures."

   o  The originator and the sponsor may be required to purchase  mortgage loans
      from the  trust in the  event  certain  breaches  of  representations  and
      warranties  have not been cured.  In  addition,  certain  parties have the
      option to purchase mortgage loans from the trust that are at least 90 days
      delinquent  under the


                                      S-24


      circumstances    described    under    "The    Pooling    and    Servicing
      Agreement--Optional  Purchase of  Defaulted  Mortgage  Loans" in this free
      writing  prospectus  and the option to purchase all of the mortgage  loans
      and REO properties in the trust and thereby effect the early retirement of
      the certificates  under the circumstances set forth under "The Pooling and
      Servicing   Agreement--Optional   Termination"   in  this   free   writing
      prospectus. In addition, Option One Mortgage Corporation generally will be
      required to repurchase from the trust certain mortgage loans for which the
      first  scheduled  monthly  payment due after their purchase by the sponsor
      becomes 45 or more days  delinquent.  These  purchases  will have the same
      effect on the holders of the offered  certificates  as a prepayment of the
      mortgage loans.

   o  The servicer will generally enforce  due-on-sale  clauses contained in the
      mortgage notes in connection with transfers of mortgaged properties.

   o  If the rate of default and the amount of losses on the mortgage  loans are
      higher than you expect, then your yield may be lower than you expect.

   o  If  the  level  of   overcollateralization   falls   below  the   targeted
      overcollateralization amount for a distribution date, excess interest and,
      in certain situations,  net swap payments will be paid to the certificates
      as principal.  This will have the effect of reducing the total certificate
      principal balance of the certificates faster than the principal balance of
      the mortgage  loans until the required level of  overcollateralization  is
      reached.

Adjustable rate mortgage loan borrowers may be more likely to prepay

      Mortgage interest rates on the adjustable-rate  mortgage loans at any time
may not equal the prevailing mortgage interest rates for similar adjustable-rate
mortgage loans,  and accordingly the prepayment rate may be lower or higher than
would  otherwise  be  anticipated.  Moreover,  some  mortgagors  who  prefer the
certainty  provided  by  fixed-rate   mortgage  loans  may  nevertheless  obtain
adjustable-rate  mortgage loans at a time when they regard the mortgage interest
rates  (and,   therefore,   the  payments)  on  fixed-rate   mortgage  loans  as
unacceptably high. These mortgagors may be induced to refinance  adjustable-rate
mortgage  loans  when the  mortgage  interest  rates  and  monthly  payments  on
comparable  fixed-rate  mortgage loans decline to levels which these  mortgagors
regard as  acceptable,  even though these  mortgage  interest  rates and monthly
payments may be significantly  higher than the current  mortgage  interest rates
and monthly  payments on the mortgagors'  adjustable-rate  mortgage  loans.  The
ability  to  refinance  a  mortgage  loan will  depend  on a number  of  factors
prevailing at the time refinancing is desired, such as, among other things, real
estate values, the mortgagor's financial situation, prevailing mortgage interest
rates, the mortgagor's  equity in the related mortgaged  property,  tax laws and
prevailing general economic conditions.

There is a risk that interest payments on the mortgage loans may be insufficient
to maintain overcollateralization

      Because the weighted  average of the interest  rates on the mortgage loans
is expected to be higher than the weighted  average of the certificate  interest
rates on the  certificates,  the mortgage  loans are  expected to generate  more
interest  than is needed to pay  interest  owed on the  certificates  as well as
certain fees and expenses of the trust  (including  any net swap payment owed to
the swap provider and any swap  termination  payment owed to the swap  provider,
other than a swap  termination  payment  resulting from a swap provider  trigger
event).  After  these  financial  obligations  of the  trust  are  covered,  the
available  excess interest will be used to maintain  overcollateralization.  Any
remaining  interest will then be used to compensate for losses that occur on the
mortgage loans. We cannot assure you, however,  that enough excess interest will
be generated to maintain the overcollateralization  level required by the rating
agencies.  The factors  described below, as well as the factors described in the
next Risk Factor,  will affect the amount of excess  interest  that the mortgage
loans will generate:

   o  When a mortgage loan is prepaid in full or  repurchased,  excess  interest
      will  generally  be reduced  because the  mortgage  loan will no longer be
      outstanding  and  generating  interest  or,  in  the  case  of  a  partial
      prepayment, will be generating less interest.


                                      S-25


   o  Every time a mortgage loan is liquidated or written off,  excess  interest
      will be reduced  because that 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  on a
      distribution date to pay certificateholders.

   o  The certificate  interest rates of the offered  certificates  are based on
      one-month LIBOR while the  adjustable-rate  mortgage loans have rates that
      are adjustable based on six-month LIBOR and the fixed-rate  mortgage loans
      have rates that do not adjust. As a result, the certificate interest rates
      on the offered certificates may increase relative to interest rates on the
      mortgage loans, thus requiring that more of the interest  generated by the
      mortgage loans be applied to cover interest on the offered certificates.

Effects of mortgage interest rates and other factors on the certificate interest
rates of the offered certificates

      The yields to maturity on the offered  certificates may be affected by the
inclusion  of  fixed-rate  mortgage  loans  and the  resetting  of the  mortgage
interest rates on the adjustable-rate mortgage loans on their related adjustment
dates due to the factors set forth  below.  The mortgage  interest  rates on the
fixed-rate  mortgage  loans  are  fixed and will not vary with any index and the
mortgage  interest  rates on the  adjustable-rate  mortgage  loans  are based on
six-month LIBOR and do not adjust for periods ranging from, in substantially all
cases,  two to five  years  after  the  dates of their  origination,  while  the
certificate  interest rates on the offered  certificates  are based on one-month
LIBOR,  are subject to the applicable  maximum rate cap and the applicable  cap,
and are adjusted monthly.  This mismatch of indices and adjustment frequency may
cause  the  one-month  LIBOR-based  certificate  interest  rates on the  offered
certificates to increase relative to the mortgage interest rates on the mortgage
loans,  which would require a greater  portion of the interest  generated by the
mortgage  loans  to  be  applied  to  cover  interest  accrued  on  the  offered
certificates,  and could result in the  limitation of the  certificate  interest
rates on some or all of the offered certificates by the related group cap or the
pool cap,  as  applicable,  and could  therefore  adversely  affect the yield to
maturity on such certificates.  The group caps are equal to the weighted average
of the interest  rates on the mortgage  loans in the related loan group,  net of
certain  expenses of the trust  (including any net swap payment owed to the swap
provider and any swap termination payment owed to the swap provider,  other than
a swap termination  payment due to a swap termination  trigger event).  The pool
cap is equal to the weighted average of the group caps, weighted on the basis of
the group subordinate  amount for each loan group. In addition,  you should note
that the  group  caps and the pool cap will  decrease  if the  related  mortgage
loans,  in the case of the group caps, or all the mortgage loans, in the case of
the pool cap, with  relatively  high mortgage  interest rates prepay at a faster
rate than the other mortgage loans in the group or the pool, as applicable, with
relatively low mortgage interest rates,  which will increase the likelihood that
the  group  caps or the pool cap will  apply to limit the  certificate  interest
rates on one or more classes of the offered certificates.

      If the certificate  interest rate on any class of the offered certificates
is  limited  by a group  cap or the  pool  cap for any  distribution  date,  the
resulting cap carryover  amounts may be recovered by the holders of such classes
of certificates on that same distribution date or on future  distribution dates,
to the extent that on that distribution date or future  distribution dates there
are any available  funds  remaining  after certain  other  distributions  on the
offered  certificates  and the Class B  Certificates  and the payment of certain
fees and expenses of the trust  (including any net swap payment owed to the swap
provider and any swap termination payment owed to the swap provider,  other than
a swap termination  payment due to a swap termination trigger event). You should
note,  however,   that  if  the  pass-through  rate  on  any  class  of  offered
certificates  is based on the  applicable  maximum  rate cap,  the amount of cap
carryover  will be less  during such  period on those  certificates  than if the
pass-through rate were based on one-month LIBOR plus the applicable  margin. The
ratings on the offered  certificates will not address the likelihood of any such
recovery of cap carryover amounts by holders of such certificates.

      Amounts  distributed  on the  offered  certificates  in  respect  of  such
shortfalls may be supplemented  by net payments  received from the swap provider
under the interest rate swap agreement,  to the extent that the floating payment
payable  by  the  swap  provider  exceeds  the  fixed  payment  payable  by  the
supplemental  interest  trust  on any  distribution  date,  and such  amount  is
available in the priorities described in this free writing prospectus.  However,
the  amount  received  from the swap  provider  under  the  interest  rate  swap
agreement may be insufficient to pay


                                      S-26


holders of the  applicable  certificates  the full amount of interest which they
would have received absent the limitations of the related cap.

There are risks relating to alternatives to foreclosure

      Certain  mortgage loans may become  delinquent after the closing date. The
servicer may either foreclose on any such mortgage loan or work out an agreement
with the mortgagor if the delinquency is not cured, which may involve waiving or
modifying  certain  terms of the  mortgage  loan.  If the  servicer  extends the
payment  period or accepts a lesser  amount than stated in the mortgage  note in
satisfaction of the mortgage note, your yield may be reduced.

Nature of sub-prime mortgage loans may increase risk of loss

      Substantially  all of the mortgage loans are of sub-prime  credit quality;
i.e., do not meet the customary  credit standards of Fannie Mae and Freddie Mac.
The originator  makes sub-prime  mortgage loans to borrowers that typically have
limited  access to  traditional  mortgage  financing  for a variety of  reasons,
including  impaired or limited past credit  history,  lower credit scores,  high
loan-to-value  ratios  or high  debt-to-income  ratios.  As a  result  of  these
factors,  delinquencies  and liquidation  proceedings are more likely with these
mortgage loans than with mortgage loans that satisfy customary credit standards.
In the event the mortgage  loans in the mortgage  pool do become  delinquent  or
subject to liquidation,  you may face delays in receiving payment and may suffer
losses if the  credit  enhancements  are  insufficient  to cover the  delays and
losses.

High combined loan-to-value ratios increase risk of loss

      Mortgage loans with high combined loan-to-value ratios leave the mortgagor
with little to no equity in the related  mortgaged  property.  See the  mortgage
loan  tables in  Appendix  A to this free  writing  prospectus  for  information
regarding the combined  loan-to-value  ratios of the mortgage loans. No mortgage
loan had a combined  loan-to-value  ratio  exceeding  100.00% as of the  cut-off
date.  An overall  decline in the  residential  real  estate  market,  a rise in
interest  rates over a period of time and the general  condition  of a mortgaged
property, as well as other factors, may have the effect of reducing the value of
such mortgaged  property from the appraised  value at the time the mortgage loan
was originated.  If there is a reduction in value of the mortgaged property, the
combined  loan-to-value  ratio  may  increase  over  what it was at the  time of
origination.  Such an  increase  may  reduce  the  likelihood  that  liquidation
proceeds or other  proceeds  will be  sufficient  to pay off the  mortgage  loan
fully.  There can be no assurance that the combined  loan-to-value  ratio of any
mortgage loan determined at any time after  origination is less than or equal to
its  original  combined  loan-to-value  ratio.  Additionally,  the  originator's
determination  of the value of a mortgaged  property used in the  calculation of
the  combined  loan-to-value  ratios of the  mortgage  loans may differ from the
appraised value of such mortgaged property or the actual value of such mortgaged
property.

The interest rate swap agreement is subject to counterparty risk

      The assets of the  supplemental  interest  trust include the interest rate
swap agreement which will require the swap provider to make certain  payments in
the    circumstances    set   forth   herein   under    "Description    of   the
Certificates--Interest  Rate  Swap  Agreement,  the Swap  Provider  and the Swap
Account."  To the extent  that  payments on the  certificates  depend in part on
payments to be received by the  supplemental  interest  trust  trustee under the
interest rate swap agreement, the ability of the issuing entity to make payments
on the certificates will be subject to the credit risk of the swap provider.

There is no assurance that amounts will be received under the interest rate swap
agreement

      Any amounts  received from the swap provider  under the interest rate swap
agreement  will be applied as described in this free writing  prospectus  to pay
interest and basis risk shortfalls, to maintain overcollateralization and to pay
unpaid  realized loss amounts.  However,  no amounts will be payable by the swap
provider  unless the floating amount owed by the swap provider with respect to a
distribution  date  exceeds  the fixed  amount  owed to the swap  provider  with
respect to that  distribution  date (other than minimal amounts resulting from a
fixed  accrual  period for the  supplemental  interest  trust's  payments  and a
floating  period  for the swap  provider's  payments).  This will only


                                      S-27


occur in periods when one-month  LIBOR (as  determined  pursuant to the interest
rate swap agreement) exceeds 5.0625%.  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 cover  interest  shortfalls
arising  from the  operation  of the  group  caps or the pool cap,  to  maintain
required overcollateralization or to pay realized losses.

      In addition,  to the extent that distributions on the offered certificates
depend in part on payments to be received  by the  supplemental  interest  trust
under the interest  rate swap  agreement,  the ability of the issuing  entity to
make such  distributions will be subject to the credit risk of the swap provider
under the interest rate swap agreement.  The credit ratings of the swap provider
are lower than the ratings assigned to the senior  certificates.  There can also
be no assurance  that in the event of an early  termination of the interest rate
swap agreement, the depositor will be able to obtain a replacement interest rate
swap  agreement.  See  "Description  of  the  Certificates--Interest  Rate  Swap
Agreement,  the  Swap  Provider  and the  Swap  Account"  in this  free  writing
prospectus.

The credit  rating of the swap  provider  could affect the rating of the offered
certificates

      The swap provider has, as of the date of this free writing  prospectus,  a
long-term  debt  rating  of "AA"  from  Standard  & Poor's,  a  division  of The
McGraw-Hill  Companies,  Inc., "Aa1" from Moody's  Investors  Service,  Inc. and
"AA-" from Fitch Ratings.  The ratings on the offered certificates are dependent
in part on the credit  ratings of the swap  provider.  If a credit rating of the
swap provider is qualified, reduced or withdrawn and an arrangement satisfactory
to rating  agencies is not obtained in accordance with the terms of the interest
rate swap agreement,  the ratings on the offered  certificates may be qualified,
reduced or withdrawn.  As a result,  the value and  marketability of the offered
certificates   may   be   adversely   affected.    See   "Description   of   the
Certificates--Interest  Rate  Swap  Agreement,  the Swap  Provider  and the Swap
Account" in this free writing prospectus.

Payments due to swap provider may result in losses on certificates

      Any net  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  certificate  interest  rates  of the
certificates.  If the rate of  prepayment  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, any termination payment payable to the swap provider
(other than a termination  payment resulting from a swap provider trigger event)
in the event of early  termination  of the  interest  rate swap  agreement  will
reduce amounts available for distribution to certificateholders.

      Upon  early   termination  of  the  interest  rate  swap  agreement,   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 supplemental  interest trust is required to make a swap termination payment,
that payment will be paid prior to the related  distribution  date,  and,  until
paid in full, prior to any subsequent distribution dates, generally prior to any
distribution  to  certificateholders.  This  feature may result in losses on the
certificates.   Due  to  the  priority  of   distributions,   the   subordinated
certificates  will bear the effects of any shortfalls  resulting from a net swap
payment or swap termination  payment by the  supplemental  interest trust before
such  effects are borne by the senior  certificates  and one or more  classes of
subordinated certificates may suffer a loss as a result of such payment.

Some of the  mortgage  loans have an initial  interest  only  period,  which may
result in increased delinquencies and losses or rates of prepayment

      Some of the  mortgage  loans do not  require  any  scheduled  payments  of
principal  during their  initial  interest  only period,  but require  scheduled
payments of interest  only during this time.  See the mortgage loan tables under
"Summary of Free Writing  Prospectus"  in this free writing  prospectus  for the
percentages  of the mortgage loans in each loan group and the mortgage pool that
are interest only mortgage loans.  During this period,  the payment due from the
related  mortgagor  will be less than that of a  traditional  mortgage  loan. In
addition, the principal balance of


                                      S-28


the  mortgage  loan  will not be  reduced  (except  in the case of  prepayments)
because  there will be no scheduled  monthly  payments of principal  during this
period.  Accordingly,  no principal  payments will be distributed to the related
certificates  from these mortgage loans during their interest only period except
in the case of a prepayment.

      After the initial  interest  only  period,  payments  on an interest  only
mortgage  loan will be  recalculated  to  amortize  fully its  unpaid  principal
balance  over its  remaining  life and the  mortgagor  will be  required to make
scheduled  payments of both  principal  and  interest.  The required  payment of
principal will increase the burden on the mortgagor and may increase the risk of
default  under the related  mortgage  loan.  This  increase  in the  mortgagor's
scheduled  monthly  payment  will occur when the  mortgagor's  monthly  interest
payment  may also be  increasing  as a result  of an  increase  in the  mortgage
interest rate on an  adjustment  date.  In  underwriting  interest only mortgage
loans,  the originator  generally does not consider the ability of mortgagors to
make  payments of  principal  at the end of the  interest  only  period.  Higher
scheduled monthly payments may induce the related  mortgagors to refinance their
mortgage  loans,  which would  result in higher  prepayments.  In  addition,  in
default situations losses may be greater on these mortgage loans because they do
not amortize  during the initial  period.  Losses,  to the extent not covered by
credit enhancement, will be allocated to the certificates.

      Mortgage loans with an initial  interest only period are relatively new in
the secondary  mortgage  market.  The performance of these mortgage loans may be
significantly  different from mortgage loans that amortize from origination.  In
particular,  these  mortgagors  may be more likely to refinance  their  mortgage
loans,  which may result in higher prepayment speeds than would otherwise be the
case.

The rate of default on mortgage  loans that are  secured by investor  properties
may be higher than on other mortgage loans.

      Certain of the  mortgage  loans are  expected  to be  secured by  investor
properties.  See the  mortgage  loan  tables  under  "Summary  of  Free  Writing
Prospectus" in this free writing  prospectus for the percentages of the mortgage
loans in each loan group and the  mortgage  pool that are  secured  by  investor
properties.   An  investor  property  is  a  property  which,  at  the  time  of
origination,  the  mortgagor  represented  would not be used as the  mortgagor's
primary  residence  or second home.  Because the  mortgagor is not living on the
property,  the mortgagor may be more likely to default on the mortgage loan than
on a comparable  mortgage  loan secured by a primary  residence,  or to a lesser
extent,  a second home.  In addition,  income  expected to be generated  from an
investor property may have been considered for underwriting purposes in addition
to the  income of the  mortgagor  from other  sources.  Should  this  income not
materialize, it is possible the mortgagor would not have sufficient resources to
make payments on the mortgage loan.

Balloon mortgage loans increase the risk of loss

      Certain of the mortgage loans are expected to be balloon  mortgage  loans.
See the mortgage loan tables under "Summary of Free Writing  Prospectus" in this
free writing  prospectus for the  percentages of the mortgage loans in each loan
group and the mortgage pool that are balloon  mortgage loans.  Balloon  mortgage
loans  require  a  mortgagor  to make a large  scheduled  lump  sum  payment  of
principal  at the end of the loan term.  If the  mortgagor  is unable to pay the
lump sum or refinance  such  amount,  you may suffer a loss.  In  addition,  the
servicer will not advance the unpaid principal  balance remaining at maturity of
a balloon mortgage loan.

There are risks relating to simultaneous second mortgage loans

      Certain of the mortgage  loans may have been  originated by the originator
simultaneously  with a second lien mortgage  loan.  See the mortgage loan tables
under "Summary of Free Writing  Prospectus" in this free writing  prospectus for
the  percentages  of the mortgage loans in each loan group and the mortgage pool
that have been  originated by the originator  simultaneously  with a second lien
mortgage  loan.  These second lien mortgage  loans may or may not be included in
the trust.  With respect to mortgage  loans that have junior lien mortgage loans
encumbering the same mortgaged property,  foreclosure frequency may be increased
relative to mortgage loans that do not have  subordinate  financing  behind them
because  mortgagors  have less equity in the mortgaged  property.  Further,  the
servicer  may  declare a default on the junior  lien loan even  though the first
lien loan is current,  which would  constitute a default on the first lien loan.
In  addition  to the  mortgage  loans  discussed  above  that have  simultaneous
subordinate financing provided by the originator,  with respect to certain other
mortgage  loans, at the


                                      S-29


time of  origination  of the first lien  mortgage  loan,  the related  mortgaged
property was also encumbered by a second lien mortgage to a mortgagee other than
the  originator.  Investors  should  also note  that any  mortgagor  may  obtain
subordinate financing at any time subsequent to the date of origination of their
mortgage loan from the originator or from any other lender.

There are risks relating to subordinate loans

      Certain of the mortgage  loans  evidence a second lien that is subordinate
to the rights of the  mortgagee  under a first  mortgage.  See the mortgage loan
tables  under  "Summary  of  Free  Writing  Prospectus"  in  this  free  writing
prospectus for the  percentages of the mortgage loans in each loan group and the
mortgage  pool that evidence a second lien.  The proceeds from any  liquidation,
insurance  or  condemnation   proceedings  will  be  available  to  satisfy  the
outstanding  principal  balance of such junior mortgage loans only to the extent
that the claims of the related  senior  mortgage  loans have been  satisfied  in
full,  including any  foreclosure  costs.  In  circumstances  where the servicer
determines that it would be  uneconomical to foreclose on the related  mortgaged
property, the servicer may write-off the entire outstanding principal balance of
the related  mortgage  loan as bad debt.  The foregoing  considerations  will be
particularly  applicable  to junior  mortgage  loans  that  have  high  combined
loan-to-value  ratios  because the  servicer is more  likely to  determine  that
foreclosure  would be  uneconomical.  You should  consider  the risk that to the
extent  losses on junior  mortgage  loans are not  covered by  available  credit
enhancement,   such  losses  will  be  borne  by  the  holders  of  the  offered
certificates.

There are risks relating to geographic concentration of the mortgage loans

      The following  chart lists the states with the highest  concentrations  of
mortgage  loans  for each  loan  group and in the  mortgage  pool,  based on the
aggregate  principal  balance of the  mortgage  loans in each loan group and the
mortgage pool as of the cut-off date.

      California,  Florida and several  other  states have  experienced  natural
disasters, such as earthquakes,  fires, floods and hurricanes,  which may not be
fully insured  against and which may result in property damage and losses on the
mortgage loans.

      In addition,  the conditions below will have a disproportionate  impact on
the mortgage loans in general:

   o  Economic  conditions  in states  listed  above which may or may not affect
      real  property  values may affect the ability of mortgagors to repay their
      loans on time.

   o  Declines in the residential real estate markets in the states listed above
      may reduce the values of properties  located in those states,  which would
      result in an increase in the combined loan-to-value ratios.

   o  Any  increase  in the  market  value of  properties  located in the states
      listed  above would reduce the  combined  loan-to-value  ratios and could,
      therefore,   make  alternative  sources  of  financing  available  to  the
      mortgagors  at lower  interest  rates,  which could result in an increased
      rate of prepayment of the mortgage loans.

Residential real estate values may fluctuate and adversely affect your
investment

      There can be no assurance  that values of the  mortgaged  properties  have
remained  or will  remain at their  levels on the  dates of  origination  of the
related  mortgage  loans.  The value of any mortgaged  property  generally  will
change over time from its value on the appraisal or sales date.  If  residential
real estate values  generally or in a particular  geographic  area decline,  the
combined  loan-to-value  ratios of the  mortgage  loans  shown in the  tables in
Appendix  A might not be a  reliable  indicator  of the rates of  delinquencies,
foreclosures  and  losses  that  could  occur  on  the  mortgage  loans.  If the
residential real estate market should  experience an overall decline in property
values


                                      S-30


large enough to cause the  outstanding  balances of the  mortgage  loans and any
secondary  financing on the related mortgaged  properties to equal or exceed the
value of the mortgaged properties, delinquencies,  foreclosures and losses could
be higher than those now generally  experienced in the mortgage lending industry
or in the sponsor's prior securitizations involving the depositor.

      In addition,  adverse economic  conditions and other factors (which may or
may not affect real property  values) may affect the mortgagors'  timely payment
of  scheduled  payments of principal  and  interest on the  mortgage  loans and,
accordingly,  the actual rates of  delinquencies,  foreclosures  and losses with
respect to any  mortgage  pool.  These other  factors  could  include  excessive
building  resulting  in an  oversupply  of  housing  in a  particular  area or a
decrease in employment reducing the demand for housing in an area. To the extent
that credit  enhancements do not cover such losses,  your yield may be adversely
impacted.

Credit scores may not accurately predict the likelihood of default

      The originator  generally  uses credit scores as part of its  underwriting
process.  The tables in Appendix A show credit scores for the  mortgagors of the
mortgage loans  obtained at the time of  origination of their mortgage  loans. A
credit score purports only to be a measurement of the relative  degree of risk a
borrower  represents to a lender,  i.e.,  that a borrower with a higher score is
statistically  expected to be less likely to default in payment  than a borrower
with a lower  score.  In  addition,  it should be noted that credit  scores were
developed  to indicate a level of default  probability  over a two-year  period,
which  does not  correspond  to the life of most  mortgage  loans.  Furthermore,
credit  scores  were  not  developed  specifically  for use in  connection  with
mortgage loans, but for consumer loans in general.  Therefore,  credit scores do
not  address  particular  mortgage  loan   characteristics  that  influence  the
probability of repayment by the borrower. None of the depositor,  the sponsor or
the  originator  makes any  representations  or warranties as to any  borrower's
current  credit score or the actual  performance  of any mortgage loan or that a
particular credit score should be relied upon as a basis for an expectation that
a borrower will repay its mortgage loan according to its terms.

The recording of the mortgages in the name of MERS may affect the yield on your
certificates

      The mortgages or  assignments  of mortgage for some of the mortgage  loans
have been  recorded in the name of  Mortgage  Electronic  Registration  Systems,
Inc.,  or MERS,  solely as nominee for the  originator  and its  successors  and
assigns,  including the trust.  Subsequent  assignments  of those  mortgages are
registered electronically through the MERS system. However, if MERS discontinues
the MERS system and it becomes  necessary to record an assignment of mortgage to
the trustee,  any related expenses will be paid by the trust and will reduce the
amount available to make distributions on the certificates.

      The  recording  of  mortgages  in the  name of MERS  is a  relatively  new
practice in the mortgage lending industry.  Public recording officers and others
may  have  limited,  if  any,  experience  with  lenders  seeking  to  foreclose
mortgages,  assignments of which are registered with MERS.  Accordingly,  delays
and additional  costs in  commencing,  prosecuting  and  completing  foreclosure
proceedings and conducting  foreclosure sales of the mortgaged  properties could
result.  Those  delays  and  the  additional  costs  could  in  turn  delay  the
distribution  of  liquidation  proceeds to  certificateholders  and increase the
amount of losses on the mortgage loans. In that regard, a Florida court recently
ruled that MERS lacked standing to pursue  foreclosure  proceedings on behalf of
the  beneficial  owners of several  mortgage notes who were not named parties to
the proceedings.

There are risks in holding subordinated certificates

      The  protections  afforded  the senior  certificates  in this  transaction
create  risks for the  subordinated  certificates.  Prior to any purchase of any
subordinated  certificates,  consider the  following  factors that may adversely
impact your yield:

   o  Because the  subordinated  certificates  receive  interest  and  principal
      distributions  after the senior  certificates  receive such distributions,
      there is a greater likelihood that the subordinated  certificates will not
      receive the  distributions  to which they are entitled on any distribution
      date.


                                      S-31


   o  If the  servicer  determines  not to  advance a  delinquent  payment  on a
      mortgage  loan  because such amount is not  recoverable  from a mortgagor,
      there may be a shortfall in distributions  on the certificates  which will
      impact the subordinated certificates.

   o  The portion of the  shortfalls  in the amount of interest  collections  on
      mortgage  loans that are  attributable  to prepayments in full and are not
      covered by the servicer and  shortfalls  in interest  collections  arising
      from the timing of partial principal prepayments may result in a shortfall
      in distributions on the certificates, which will disproportionately impact
      the subordinated certificates.

   o  The  subordinated  certificates  are not  expected  to  receive  principal
      distributions  until,  at the  earliest,  October  2009 (unless the senior
      certificates are reduced to zero prior to such date) or such later date as
      provided  in this  free  writing  prospectus.  As a result,  the  weighted
      average lives of such  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
      subordinated certificates, the holders of such certificates have a greater
      risk of suffering losses on their investments.

   o  Because  the   sequential   mezzanine   certificates   receive   principal
      distributions  sequentially  after the stepdown date, the weighted average
      lives of the more subordinate  sequential  mezzanine  certificates will be
      longer than if these principal  distributions  were made to the sequential
      mezzanine  certificates  in a pro rata fashion.  As a result of the longer
      weighted  average  lives  of the  more  subordinate  sequential  mezzanine
      certificates,  the  holders of such  certificates  have a greater  risk of
      suffering losses on their investments.

   o  Losses  resulting from the  liquidation  of defaulted  mortgage loans will
      first  reduce  monthly  excess  cashflow  and  then  reduce  the  level of
      overcollateralization,  if any, for the  certificates.  Realized losses on
      the  mortgage  loans,  to the  extent  they  exceed  the  amount of excess
      interest and overcollateralization following distributions of principal on
      the related distribution date and any net swap payments received under the
      interest  rate  swap  agreement  will  be  allocated  to the  subordinated
      certificates  in  reverse  order of  payment  priority.  No  principal  or
      interest  will be  distributable  on the  amount by which the  certificate
      principal balance of a class has been reduced by a realized loss allocated
      to a  subordinated  certificate  (except  where  a  certificate  principal
      balance has been increased by a subsequent  recovery).  A loss  allocation
      results in a reduction in a certificate  balance  without a  corresponding
      distribution  of cash to the  holder.  A lower  certificate  balance  will
      result in less interest accruing on the certificate.

   o  The earlier in the transaction that a loss on a mortgage loan occurs,  the
      greater the impact on yield.

      See "Description of the Certificates" and "Yield,  Prepayment and Maturity
Considerations" in this free writing prospectus for more detail.

Decrement tables are based upon assumptions and models

      The  decrement  tables set forth in  Appendix B have been  prepared on the
basis  of the  modeling  assumptions  described  under  "Yield,  Prepayment  and
Maturity   Considerations--Weighted   Average   Lives."  There  will  likely  be
discrepancies  between the characteristics of the actual mortgage loans included
in each loan group and the characteristics of the assumed mortgage loans used in
preparing the decrement tables. Any such discrepancy may have an effect upon the
percentages of original certificate  principal balances outstanding set forth in
the   decrement   tables  (and  the  weighted   average  lives  of  the  offered
certificates).  In addition, to the extent that the mortgage loans that actually
are included in a loan group have characteristics that differ from those assumed
in preparing the decrement tables, the certificate  principal balance of a class
of offered certificates could be reduced to zero earlier or later than indicated
by the decrement tables.

The rights of the NIMS Insurer could adversely affect the offered certificates

      After the closing date, a separate  entity may be established to issue net
interest margin securities secured by all or a portion of the Class CE and Class
P Certificates.  A NIMS Insurer may issue a financial  guaranty insurance policy
that  guarantees  payments  on  those  securities.  If the net  interest  margin
securities  are so insured,  the NIMS


                                      S-32


Insurer will have a number of rights under the pooling and  servicing  agreement
that could  adversely  affect  certificateholders.  Pursuant  to the pooling and
servicing  agreement,  unless the NIMS Insurer fails to make a required  payment
under the policy insuring the net interest margin securities or the NIMS Insurer
is the subject of a bankruptcy proceeding,  the NIMS Insurer will be entitled to
exercise,  among  others,  the  following  rights of the  holders of the offered
certificates, without their consent, and the holders of the offered certificates
will be able to exercise such rights only with the prior written  consent of the
NIMS  Insurer.  Rights of the NIMS  Insurer  under  the  pooling  and  servicing
agreement may include, but are not limited to, the following:

   o  the right to direct the trustee to terminate the rights and obligations of
      the servicer  under the pooling and servicing  agreement upon a default by
      the servicer;

   o  the right to remove the trustee or any co-trustee  pursuant to the pooling
      and  servicing  agreement  for  failure  of  such  party  to  perform  its
      obligations thereunder;

   o  the right to direct the trustee to make  investigations  and take  actions
      pursuant to the pooling and servicing agreement;

   o  the right to purchase all of the mortgage  loans and REO properties in the
      trust fund and thereby  effect the early  retirement  of the  certificates
      under the  circumstances  set  forth  under  "The  Pooling  and  Servicing
      Agreement--Optional Termination" in this free writing prospectus; and

   o  the right to purchase mortgage loans delinquent in payment 90 days or more
      under the  circumstances  set  forth  under  "The  Pooling  and  Servicing
      Agreement--Optional Purchase of Defaulted Mortgage Loans."

      In  addition,  unless the NIMS  Insurer  fails to make a required  payment
under the policy insuring the net interest margin securities or the NIMS Insurer
is the subject of a bankruptcy  proceeding,  the NIMS Insurer's  consent will be
required before, among other things,

   o  the appointment of any co-trustee;

   o  any otherwise  permissible  waivers of prepayment charges or extensions of
      due dates for payment granted by the servicer with respect to more than 5%
      of the number of mortgage loans; or

   o  any amendment to the pooling and servicing agreement.

      Investors in the offered certificates should note that:

   o  any insurance  policy issued by the NIMS Insurer will not cover,  and will
      not benefit in any manner whatsoever the offered certificates;

   o  the rights granted to the NIMS Insurer are extensive;

   o  the interests of the NIMS Insurer may be inconsistent with, and adverse to
      the  interests  of the  holders of the offered  certificates  and the NIMS
      Insurer has no obligation or duty to consider the interests of the offered
      certificates  in connection  with the exercise or  nonexercise of the NIMS
      Insurer's rights; and

   o  the NIMS  Insurer's  exercise of its rights and  consents  may  negatively
      affect the offered  certificates  and the existence of the NIMS  Insurer's
      rights,  whether or not exercised,  may adversely  affect the liquidity of
      the  offered  certificates,  relative to other  asset-backed  certificates
      backed by comparable mortgage loans and with comparable payment priorities
      and ratings.

United States military operations may increase risk of shortfalls in interest


                                      S-33


      As a result of military  operations in  Afghanistan  and Iraq,  the United
States has placed a substantial number of armed forces reservists and members of
the  National  Guard on active duty  status.  It is possible  that the number of
reservists  and members of the  National  Guard placed on active duty status may
remain at high levels for an extended  time.  To the extent that a member of the
military,  or a member of the armed  forces  reserves or  National  Guard who is
called to active  duty,  is a  mortgagor  of a mortgage  loan in the trust,  the
interest  rate  limitation  of the  Servicemembers  Civil  Relief  Act  and  any
comparable state law, will apply.  Substantially  all of the mortgage loans have
mortgage  interest rates which exceed such limitation,  if applicable.  This may
result in interest  shortfalls on the mortgage  loans,  which,  in turn, will be
allocated   ratably  in  reduction  of  accrued   interest  on  all  classes  of
interest-bearing  certificates,  irrespective of the availability of excess cash
flow or other credit  enhancement.  None of the originator,  the depositor,  the
underwriter,  the sponsor,  the servicer or any other party has taken any action
to  determine  whether  any of the  mortgage  loans  would be  affected  by such
interest  rate  limitation.   See  "Description  of  the  Certificates--Interest
Distributions" in this free writing prospectus and "Certain Legal Aspects of the
Mortgage Loans--Servicemembers Civil Relief Act" in the prospectus.

                                THE MORTGAGE POOL

      The descriptions of the Mortgage Loans and the Mortgaged  Properties below
and in Appendix A are based upon the  expected  characteristics  of the Mortgage
Loans  included in the Mortgage  Pool as of the close of business on the Cut-off
Date (the "Mortgage Loans").  The Principal Balances of the Mortgage Loans shown
have been  adjusted for the  scheduled  principal  payments due on or before the
Cut-off Date (each, a "Cut-off Date Principal Balance").

      Prior to the Closing  Date,  Mortgage  Loans may be removed  from the loan
groups and other  Mortgage  Loans may be  substituted  for them.  The  Depositor
believes  that the  information  set forth in this free  writing  prospectus  is
representative  of the  characteristics  of the  loan  groups  as  they  will be
constituted  on  the  Closing  Date.  Unless  the  context  requires  otherwise,
references  below and in Appendix A to  percentages  of the Mortgage  Loans in a
loan group are approximate percentages of the aggregate Principal Balance of the
Mortgage Loans in the loan group as of the Cut-off Date and references  below to
percentages of all Mortgage Loans are  approximate  percentages of the aggregate
Principal  Balance of the  Mortgage  Loans in all loan  groups as of the Cut-off
Date.

General

      The assets  included in the Trust will  consist  primarily  of a pool (the
"Mortgage  Pool")  of  closed-end,   fixed-rate  and  adjustable-rate  sub-prime
mortgage loans (the  "Mortgage  Loans").  The "Principal  Balance" of a Mortgage
Loan, as of any date, is equal to the principal balance of such Mortgage Loan at
its origination,  less the sum of (i) all collections and other amounts credited
against the  principal  balance of any such  Mortgage  Loan,  (ii) the principal
portion  of  Advances,  (iii) any  Deficient  Valuation  and (iv) any  principal
reduction resulting from a Servicer Modification. The "Pool Balance" is equal to
the aggregate of the Principal Balances of the Mortgage Loans in all loan groups
as of any date of determination.

      The  Mortgage  Pool  will  consist  of  fixed-rate   Mortgage-Loans   (the
"Fixed-Rate   Mortgage   Loans")  and   adjustable-rate   Mortgage   Loans  (the
"Adjustable-Rate   Mortgage  Loans").   All  of  the  Mortgage  Loans  that  are
Adjustable-Rate  Mortgage Loans have an initial fixed mortgage interest rate for
two years, three years, five years or fifteen years.

      The  Mortgage  Loans are  secured  by  mortgages,  deeds of trust or other
similar security instruments (each, a "Mortgage") which create a first or second
lien  on  one-  to  four-family  residential  properties  consisting  of one- to
four-family dwelling units and individual  condominium units (each, a "Mortgaged
Property"). All of the Mortgage Loans (other than one Mortgage Loan representing
approximately  0.05% of the Pool Balance as of the Cut-off Date) have  scheduled
Monthly  Payments  due on the  first  day of the  month  (the day  such  Monthly
Payments  are due with  respect  to each  Mortgage  Loan,  a "Due  Date").  Each
Mortgage  Loan  accrues  interest  at a per annum rate (the  "Mortgage  Interest
Rate") specified in the related mortgage note.

      Certain of the  Mortgage  Loans will  provide for  interest  only  Monthly
Payments for the first 60 months of the term of such  Mortgage  Loans (each,  an
"Interest  Only Mortgage  Loan").  See "Summary of Free Writing  Prospectus--The
Mortgage Pool" for the  percentages of the Mortgage Loans that are Interest Only
Mortgage Loans


                                      S-34


in each loan group and the Mortgage Pool. The Monthly  Payments for the Mortgage
Loans that are Interest Only Mortgage  Loans will include  accrued  interest and
principal  on these  Mortgage  Loans  beginning in the 61st month of the term of
these Mortgage Loans. As a result of this payment  structure,  Monthly  Payments
beginning  in  the  61st  month  of the  term  of  such  Mortgage  Loans  may be
significantly  larger  than the first 60  Monthly  Payments  required  under the
related mortgage notes.

      Certain of the Mortgage  Loans  provide for payment by the  mortgagor of a
prepayment charge in limited circumstances on certain prepayments.  See "Summary
of Free  Writing  Prospectus--The  Mortgage  Pool"  for the  percentages  of the
Mortgage  Loans in each loan group and the  Mortgage  Pool that  provide for the
payment of a prepayment charge. No such prepayment charge will be distributed to
the holders of the Offered Certificates.

      The  Mortgage  Pool has been  divided  into three loan groups as described
under "Summary of Free Writing Prospectus--The Mortgage Pool."

      All  of  the  Adjustable-Rate   Mortgage  Loans  provide  for  semi-annual
adjustment  to  the  Mortgage   Interest  Rate  thereon  and  for  corresponding
adjustments  to the Monthly  Payment  amount due  thereon,  in each case on each
adjustment date applicable  thereto (each such date, an "Adjustment  Date").  On
each  Adjustment  Date for each  Adjustable-Rate  Mortgage  Loan,  the  Mortgage
Interest Rate thereon will be adjusted to equal the sum of Six-Month  LIBOR (the
"Index")  and a fixed  percentage  amount (the  "Gross  Margin").  The  Mortgage
Interest  Rate on each such  Adjustable-Rate  Mortgage Loan will not increase or
decrease by more than a percentage specified in the related mortgage note on the
first related Adjustment Date (the "Initial Periodic Rate Cap") and a percentage
on any Adjustment  Date  thereafter  (the  "Periodic  Rate Cap").  Each Mortgage
Interest Rate on each Adjustable-Rate  Mortgage Loan will not exceed a specified
maximum Mortgage Interest Rate over the life of such Mortgage Loan (the "Maximum
Mortgage  Interest Rate") or be less than a specified  minimum Mortgage Interest
Rate over the life of such Mortgage Loan (the "Minimum Mortgage Interest Rate").

      Effective  with the  first  Monthly  Payment  due on each  Adjustable-Rate
Mortgage Loan after each related  Adjustment  Date,  the Monthly  Payment amount
will be adjusted to an amount that will amortize fully the outstanding Principal
Balance of the related  Mortgage Loan over its remaining  term, and pay interest
at the Mortgage  Interest  Rate as so adjusted.  Due to the  application  of the
Periodic  Rate  Caps and the  Maximum  Mortgage  Interest  Rates,  the  Mortgage
Interest Rate on each such Mortgage Loan, as adjusted on any related  Adjustment
Date,  may be less than the sum of the Index and the related Gross  Margin.  See
"--The Index" in this free writing prospectus.

      Certain of the  Mortgage  Loans are secured by a second  Mortgage  that is
junior to a first Mortgage on the related  Mortgaged  Property.  See "Summary of
Free Writing Prospectus--The  Mortgage Pool" for the percentages of the Mortgage
Loans in each loan group and the Mortgage Pool secured by a second Mortgage.

      None of the  Adjustable-Rate  Mortgage Loans have Mortgage  Interest Rates
that may be  converted  to fixed  Mortgage  Interest  Rates at the option of the
related mortgagor. None of the Mortgage Loans provide for negative amortization.

      Certain of the Mortgage Loans will not fully amortize by their  respective
maturity  dates  (each,  a  "Balloon  Loan").   See  "Summary  of  Free  Writing
Prospectus--The Mortgage Pool" for the percentages of the Mortgage Loans in each
loan group and the Mortgage Pool that are Balloon Loans. The Monthly Payment for
each Balloon Loan is based on an amortization schedule of 480 months, except for
the final  payment  (the  "Balloon  Payment")  which is due and payable on 360th
month following origination of such Mortgage Loan, depending on the terms of the
related mortgage note. The amount of the Balloon Payment on each Balloon Loan is
substantially in excess of the amount of the scheduled  Monthly Payment for such
Balloon Loan.

      None of the Mortgage  Loans were  Delinquent as of the Cut-off Date or any
time since origination. A Mortgage Loan is "Delinquent" if the scheduled monthly
payment of principal  and interest on such Mortgage Loan which is payable by the
related mortgagor under the related mortgage note (the "Monthly Payment") due on
a Due Date is not paid by the close of business on the next  scheduled  Due Date
for such Mortgage Loan.  Thus, a Mortgage Loan for which the mortgagor failed to
make the Monthly Payment due on September 1, 2006 will be reported as Delinquent
on  October  2,  2006 if the  payment  is not made by the close of  business  on
October 1, 2006.


                                      S-35


      The Servicer  will be required to make  servicing  advances on  Delinquent
Mortgage  Loans and make  advances  of  delinquent  payments  of  principal  and
interest on  Delinquent  Mortgage  Loans,  each to the extent such  advances are
deemed recoverable, until the earlier of such time that the Trust acquires title
to the Mortgage Loan, the Mortgage Loan is paid in full by the mortgagor,  until
the  Mortgage  Loan (or the related  Mortgaged  Property)  is disposed of by the
Trust or until recovery of all Liquidation Proceeds thereon.

      The "Combined  Loan-to-Value Ratio" of a Mortgage Loan generally means the
ratio,  expressed as a percentage of (i) the sum of (a) the principal  amount of
the Mortgage Loan at origination  plus (b) in the case of a second lien Mortgage
Loan, the outstanding amount of the first lien on the related Mortgaged Property
at the date of  origination  of the  Mortgage  Loan  over  (ii) the Value of the
related  Mortgaged  Property.  "Value"  means  with  respect  to  any  Mortgaged
Property,  the lesser  of:  (i) an amount  determined  by an  appraisal  done at
origination of the Mortgage Loan;  provided,  however, the amount may be reduced
to reflect  the results of a review of such  appraisal  in  accordance  with the
Originator's  underwriting  guidelines  and (ii) the purchase price paid for the
related  Mortgaged  Property by the Mortgagor  with the proceeds of the Mortgage
Loan;  provided,  however,  that in the case of a refinanced  Mortgage Loan, the
value of the Mortgaged Property is based solely upon clause (i) above.

      "Credit  Scores" are  statistical  credit scores obtained by many mortgage
lenders in  connection  with the loan  application  to help assess a  borrower's
credit-worthiness.  Credit Scores are  generated by models  developed by a third
party and are made available to lenders  through three national  credit bureaus.
The models were  derived by  analyzing  data on  consumers in order to establish
patterns  which are believed to be indicative of the  borrower's  probability of
default.  The Credit  Score is based on a  borrower's  historical  credit  data,
including,  among other  things,  payment  history,  delinquencies  on accounts,
levels of outstanding  indebtedness,  length of credit history, types of credit,
and bankruptcy experience.  Credit Scores generally range from approximately 300
to  approximately  850, with higher scores  indicating an individual with a more
favorable  credit  history  compared to an  individual  with a lower score.  The
Credit  Scores set forth in the table in Appendix A were  obtained at either the
time of origination of the Mortgage Loan or more recently.  The Depositor  makes
no  representations  or warranties as to the actual  performance of any Mortgage
Loan or that a  particular  Credit Score should be relied upon as a basis for an
expectation  that the  borrower  will repay the Mortgage  Loan  according to its
terms.

      The Depositor will purchase the Mortgage  Loans from the Sponsor  pursuant
to  the  Mortgage  Loan  Purchase   Agreement   (the   "Mortgage  Loan  Purchase
Agreement"),  dated  as of  the  Cut-off  Date,  between  the  Sponsor  and  the
Depositor.  Pursuant to the Pooling and Servicing Agreement,  the Depositor will
cause the  Mortgage  Loans to be  assigned to the Trustee for the benefit of the
Certificateholders.  See "The  Pooling  and  Servicing  Agreement"  in this free
writing prospectus.

      The Mortgage Loans were selected by the Sponsor,  with advice from Banc of
America  Securities LLC (the  "Underwriter")  as to the  characteristics  of the
Mortgage  Loans in each loan  group  that  will  optimize  marketability  of the
Certificates,  from the mortgage loans  purchased from the Originator  under the
Option  One  Mortgage  Loan  Purchase  Agreement,  and were  chosen  to meet the
requirements  imposed  by the rating  agencies  to  achieve  the credit  support
percentages listed under "Summary of Free Writing Prospectus--Credit Support."

      Based on the  representations  made by Option One, the Depositor  believes
that all of the Mortgage  Loans in the Mortgage  Pool were  originated by Option
One  and  one or  more  of its  affiliates  generally  in  accordance  with  the
underwriting  standards  described under  "Underwriting  Standards" in this free
writing prospectus.

      The Originator made certain  representations and warranties  regarding the
Mortgage  Loans,  as of August 31, 2006,  September  15, 2006 and  September 21,
2006, in the Flow Sale and Servicing  Agreement,  dated as of July 28, 2006 (the
"Option One Mortgage Loan Purchase Agreement"), pursuant to which Option One and
one or more of its  affiliates  sold such Mortgage  Loans to the Sponsor.  These
representations  and warranties will be assigned by the Sponsor to the Depositor
and by the Depositor to the Trustee, for the benefit of the  Certificateholders.
The  Originator,  subject to certain  limitations,  will be obligated  under the
Option One Mortgage  Loan  Purchase  Agreement  to  repurchase  or  substitute a
similar  mortgage loan for any Mortgage Loan as to which there exists  deficient
documentation or an uncured breach of any such  representation  or warranty,  if
such breach of any such  representation  or warranty  materially  and  adversely
affects the Certificateholders' interests in such Mortgage Loan.


                                      S-36


      Pursuant to the terms of the Mortgage Loan Purchase Agreement, the Sponsor
will make to the Depositor (and the Depositor will assign to the Trustee for the
benefit  of  Certificateholders)   only  certain  limited   representations  and
warranties as of the Closing Date with respect to the Mortgage Loans,  generally
intended to address the accuracy of the Mortgage  Loan  Schedule and the payment
and  delinquency  status of each Mortgage  Loan. In the event of a breach of any
such  representation  or  warranty  that  does not  constitute  a breach  of any
representation  or warranty  made by the  Originator  as  described  above,  the
Sponsor  will be  obligated  in the same manner as the  Originator  to cure such
breach or purchase or  substitute  the  affected  Mortgage  Loans,  as described
above.

      To the extent that any fact, condition or event with respect to a Mortgage
Loan  constitutes  a  breach  of  both  a  representation  and  warranty  of the
Originator  under the Option  One  Mortgage  Loan  Purchase  Agreement  with the
Sponsor and a breach of a  representation  and warranty of the Sponsor under the
Mortgage Loan Purchase  Agreement,  then the only right or remedy of the Trustee
or any Certificateholder  will be the Trustee's right to enforce the obligations
of the  Originator  under the Option One Mortgage Loan Purchase  Agreement,  and
there will be no remedy  against the Sponsor for such  breaches  (other than the
Sponsor's  obligation to reimburse the Trust, if the Originator  fails to do so,
for any  damages or costs  incurred  by the Trust as a result of a breach of the
representation  as to compliance with federal,  state or local laws with respect
to the origination of the Mortgage Loans).

      The Sponsor is selling the Mortgage  Loans without  recourse and will have
no obligation  with respect to the  Certificates in its capacity as seller other
than the cure,  repurchase  or  substitution  obligations  with  respect  to its
limited  representations  and warranties  described above and its  reimbursement
obligation described under "The Pooling and Servicing  Agreement--Assignment  of
the Mortgage Loans" in this free writing prospectus.

      See  "Description  of the  Agreements--Material  Terms of the  Pooling and
Servicing  Agreements and Underlying Servicing  Agreements--Representations  and
Warranties; Repurchases" in the prospectus.

The Index

      The Index for all the  Adjustable-Rate  Mortgage  Loans is the  average of
interbank  offered rates for six-month U.S. dollar deposits in the London market
calculated  as provided in the related note  ("Six-Month  LIBOR").  If Six-Month
LIBOR becomes unpublished or is otherwise unavailable,  the Servicer will select
an alternative index which is based upon comparable information.

Terms of the Mortgage Loans

      The Mortgage Loans accrue interest on an actuarial basis over the original
terms thereof,  calculated based on a 360-day year of twelve 30-day months. When
a full  prepayment of principal is made on a Mortgage  Loan during a month,  the
mortgagor is charged  interest only on the days of the month actually elapsed up
to the date of such prepayment,  at a daily interest rate that is applied to the
principal amount of the loan so prepaid.  When a partial prepayment of principal
is made on a  Mortgage  Loan  during a month,  the  mortgagor  generally  is not
charged  interest  on the amount of the partial  prepayment  during the month in
which such prepayment is made.

      The information set forth in the following paragraphs has been provided by
Option One Mortgage Corporation ("Option One").

General

      Option One, a California corporation headquartered in Irvine,  California,
originated or acquired all of the Mortgage Loans.

      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-prime  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  Option  One'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.  Option One 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 Option One's consolidated originations for the
fiscal years ended April 30, 2004, 2005 and 2006 and the three months ended July

                             UNDERWRITING STANDARDS

      The  Mortgage  Loans  originated  by Option One will have been  originated
generally in accordance with Option One's Non-Prime  Guidelines (the "Option One
Underwriting Guidelines").  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.


                                      S-38


      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 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 for closing. 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 bank statements.

      Lite  Documentation  is for  applicants  who  otherwise  cannot  meet  the
requirements of the Full Documentation program and requires applicants to submit
3 to 6 months' bank statements or a pay stub as verification of income.

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


                                      S-39


      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.

      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  generally  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  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


                                      S-40


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.  Upgrade points may also be earned
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.

                                  THE SERVICER

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  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, 2004, 2005 and 2006 and at July 31, 2006:

Option One Loan Servicing Portfolio--Advances

      Option One has  complied  with and  fulfilled  its  obligation  to advance
principal and interest for mortgage  loans  serviced by Option One in connection
with  securitizations  serviced  by Option One for the past three  fiscal  years
where its advancing obligations are substantially identical to those obligations
for this transaction.

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.


                                      S-41


      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 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,
2003,  2004 and 2005,  and at or for the quarter  ended June 30,  2006,  certain
information relating to the delinquency  experience (including  foreclosures) 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 (based on the OTS method).
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.

      following foreclosure or delivery of a deed in lieu of foreclosure.

(2)   The  Foreclosure  Ratio is equal to the  aggregate  principal  balance  or
      number of Foreclosed Loans divided by the aggregate  principal  balance or
      number, as applicable, of mortgage loans in the Total Portfolio at the end
      of the indicated period.

   Loan Loss Experience on Option One's Servicing Portfolio of Mortgage Loans

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

                                                                   Quarter Ended

Net Losses(1)(2)      $238,634          $239,008       $172,102       $146,096

- ----------
(1)   "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.

(2)   "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 June 2006 and claims, refunds or the collection of MI
      proceeds related to such liquidations through August 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 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


                                      S-44


process.   Option  One  maintains  separate  bank  accounts  for  each  investor
relationship in accordance with the related servicing agreement requirements.

      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.

Litigation Concerning Option One Mortgage Corporation

      In July 2004,  Option One 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 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 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.  Plaintiff's counsel filed a motion to substitute Larry and Pamela Smith
as  plaintiffs,  which  was  granted.  Option  One  filed  a  motion  to  compel
arbitration.  In a similar  action  before the same judge in the Third  Judicial
Circuit  Court in  Madison  County,  Illinois,  the Court  ruled in favor of the
defendants on the underlying per diem interest claim.

      On January 31, 2006,  the Circuit  Court of Cook County,  Illinois  County
Department,  Chancery  Division,  certified a nationwide  class  action  against
Option  One on a  complaint  brought  by Erin and  Earl  Austria,  in which  the
Austrias 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.  The Court has granted  Option One's motion for an
interlocutory appeal of the order of class certification.

      On February 28, 2006,  Option One was named as a defendant and served with
a class action complaint filed by Jeffrey Wright, et al., as plaintiffs,  in the
United States  District Court for the Central  District of California,  Southern
Division.  The complaint  alleges that Option One's affiliate H&R Block Mortgage
Corporation failed to pay overtime wages to its loan officers in accordance with
the Fair Labor Standards Act and that such alleged failure constitutes an unfair
business practice under  California's  Business and Professions Code. Option One
is named as a defendant under the theory that it and H&R Block Mortgage  operate
as a single employer. On May 1, 2006, the Court granted Option One and H&R Block
Mortgage's  motion to  transfer  the  action to the  District  Court in  Boston,
Massachusetts.  Option  One and H&R  Block  Mortgage  intend to file a motion to
compel  arbitration  after  the  case  has  been  formally  transferred  to  the
Massachusetts District Court.

      On July 28, 2006, Option One Mortgage Corporation was named as a defendant
and  served  with  a  class  action   complaint  filed  by  Chadwick   Thompson,
individually and on behalf of all persons similarly  situated who worked for the
defendants in California,  in the United States  District Court for the Southern
District  of  California.   The  complaint  alleges  that  Option  One  Mortgage
Corporation's  affiliate  H&R Block  Mortgage  Corporation  failed  to  properly
classify  and pay loan  officers  for  overtime  worked in violation of the Fair
Labor Standards Act,  California law, and California's  Unfair  Competition Law.
The complaint  further  alleges that Option One and H&R Block Mortgage failed to
provide meal and rest periods and seeks  restitution and waiting time penalties.
Option One filed an answer on August 17,  2006  denying the  allegations  in the
Complaint.

transaction and "The Sponsor" in the prospectus for more  information  about the
Sponsor and its securitization programs.

                             STATIC POOL INFORMATION

      Information  concerning  the  Sponsor's  prior  residential  mortgage loan
securitizations  involving  sub-prime  mortgage loans issued by the Depositor is
available  on the  internet at  http://www.bofa.com/abfc.  The website will also
provide  information about certain prior securitized pools of sub-prime mortgage
loans originated and serviced by Option One.

      Without  charge or  registration,  investors  can view on this website the
following information for each of those securitizations:

      o     summary initial pool information; and

      o     delinquency,  cumulative loss, and prepayment information as of each
            distribution date for the five years preceding the date of first use
            of this free writing prospectus, with respect to the Sponsor's prior
            securitized  pools of sub-prime  mortgage loans,  and for five years
            preceding the date of first use of this free writing prospectus with
            respect  to  certain  of Option  One's  prior  securitized  pools of
            sub-prime mortgage loans serviced by Option One.

      In the event any changes or updates are made to the information  regarding
these  securitizations  available on the Sponsor's  website,  the Depositor will
provide a copy of the original information upon request to any person who writes
or calls the  Depositor at 214 North Tryon  Street,  Charlotte,  North  Carolina
28255, (704) 683-4190, Attention: Luna Nguyen.

      The static pool data available on the Sponsor's website relating to any of
the  Sponsor's or Option One's  mortgage  loan  securitizations  issued prior to
January 1, 2006 is not deemed to be part of this free  writing  prospectus,  the
accompanying prospectus or the Depositor's registration statement.

      This  static  pool data may have been  influenced  in the past by  factors
beyond the Sponsor's  control,  such as unusually  robust  housing  prices,  low
interest rates and changes in product type. Therefore,  the performance of prior
residential  mortgage loan  securitizations  may not be indicative of the future
performance of the Mortgage Loans.

                                  THE DEPOSITOR

      Asset Backed Funding  Corporation is a direct  wholly-owned  subsidiary of
Banc of America Mortgage  Capital  Corporation and was incorporated in the State
of Delaware on July 23, 1997. It is not expected  that the  Depositor  will have
any business operations other than offering mortgage  pass-through  certificates
and related  activities.  The Depositor will have limited obligations and rights
under the Pooling and Servicing Agreement after the Closing Date.

      The Depositor  maintains its principal executive office at 214 North Tryon
Street, Charlotte, North Carolina 28255. Its telephone number is (704) 386-2400.

                               THE ISSUING ENTITY

      The  Issuing  Entity  will be a New York  common law trust (the  "Trust"),
formed on the Closing Date pursuant to the Pooling and Servicing Agreement.  The
Mortgage  Loans will be  deposited  by the  Depositor  into the Trust  under the
Pooling and  Servicing  Agreement as described  under "The Pooling and Servicing
Agreement--Assignment  of the Mortgage  Loans" in this free writing  prospectus.
The Trust will have no officers or directors  and no  activities  or  continuing
duties other than to hold the assets  underlying the  Certificates  and to issue
the  Certificates.  The fiscal year end of the Trust will be December 31 of each
year.


                                      S-46


      The Trust will be administered by the Trustee pursuant to the terms of the
Pooling and  Servicing  Agreement  as  described  under "The  Trustee"  and "The
Pooling and  Servicing  Agreement"  in this free  writing  prospectus  and under
"Description  of the  Agreements--Material  Terms of the Pooling  and  Servicing
Agreements and Underlying Servicing Agreements" in the prospectus.  The Trustee,
on behalf of the  Trust,  is only  permitted  to take the  actions  specifically
provided in the Pooling and  Servicing  Agreement  prior to an Event of Default.
After an Event of  Default,  the  Trustee  will take such  actions  as a prudent
person would be required to take under the same circumstances. Under the Pooling
and  Servicing  Agreement,  the Trustee on behalf of the Trust will not have the
power to issue  additional  certificates  representing  interests  in the Trust,
borrow  money on behalf of the Trust or make  loans from the assets of the Trust
to any person or entity.

      The  Issuing  Entity,  as a common law trust,  may not be eligible to be a
debtor in a bankruptcy proceeding, unless it can be characterized as a "business
trust" for purposes of the federal  bankruptcy laws.  Bankruptcy courts consider
various factors in making a determination  as to whether an entity is a business
trust, therefore it is not possible to predict with any certainty whether or not
the Issuing  Entity would be considered a "business  trust." In the event of the
insolvency or bankruptcy of the Sponsor, the Depositor or any other party to the
transaction,  it is not  anticipated  that the trust fund would become a part of
the bankruptcy estate or subject to the bankruptcy control of a third party. See
"Risk  Factors--Special  Powers  of the FDIC in the Event of  Insolvency  of the
Sponsor  Could  Delay  or  Reduce   Distributions  on  the   Certificates"   and
"--Insolvency  of the  Depositor  May Delay or Reduce  Collections  on  Mortgage
Loans" in the prospectus.

                                   THE TRUSTEE

      Wells Fargo Bank,  National  Association  ("Wells Fargo Bank") will act as
Trustee  under the  Pooling  and  Servicing  Agreement.  Wells  Fargo  Bank is a
national  banking  association  and a  wholly-owned  subsidiary of Wells Fargo &
Company.  A  diversified  financial  services  company with  approximately  $482
billion in assets,  23 million  customers and 153,000+  employees as of December
31,  2005,  Wells  Fargo & Company is a U.S.  bank  holding  company,  providing
banking, insurance, trust, mortgage and consumer finance services throughout the
United  States  and  internationally.  Wells  Fargo  Bank  provides  retail  and
commercial banking services and corporate trust,  custody,  securities  lending,
securities transfer, cash management,  investment management and other financial
and fiduciary services. The Depositor, the Sponsor and the Servicer may maintain
banking  and  other  commercial  relationships  with  Wells  Fargo  Bank and its
affiliates. Wells Fargo Bank maintains principal corporate trust offices located
at  9062  Old  Annapolis  Road,  Columbia,   Maryland  21045-1951  (among  other
locations), and its office for certificate transfer services is located at Sixth
Street and Marquette Avenue, Minneapolis, Minnesota 55479.

      Wells Fargo Bank has provided  corporate  trust services since 1934. As of
June 30, 2006,  Wells Fargo Bank acts as a trustee for a variety of transactions
and asset types,  including  corporate and municipal bonds,  mortgage-backed and
asset-backed  securities and  collateralized  debt  obligations.  As of June 30,
2006,  Wells  Fargo Bank was acting as trustee on more than  approximately  1230
series of residential  mortgage-backed  securities  with an aggregate  principal
balance of approximately $282,142,062,265.

      Under the terms of the Pooling and Servicing  Agreement,  the Trustee also
is responsible for securities  administration,  which includes pool  performance
calculations,   distribution   calculations   and  the  preparation  of  monthly
distribution  reports. As securities  administrator,  the Trustee is responsible
for the preparation and filing of all REMIC tax returns on behalf of the Issuing
Entity and the preparation of monthly  reports on Form 10-D,  current reports on
Form 8-K and annual  reports on Form 10-K that are required to be filed with the
Securities  and  Exchange  Commission  on behalf of the  Issuing  Entity and the
Depositor  will be required to sign any such  monthly or annual  reports.  Wells
Fargo Bank has been engaged in the business of securities  administration  since
June 30, 1995. As of June 30, 2006, was acting as securities  administrator with
respect to more than $894,733,136,436 of outstanding residential mortgage-backed
securities.

      Wells  Fargo  Bank is acting  as  custodian  of the  mortgage  loan  files
pursuant to the Pooling and Servicing Agreement.  In that capacity,  Wells Fargo
Bank is  responsible to hold and safeguard the mortgage notes and other contents
of the mortgage files on behalf of the Trustee and the Certificateholders. Wells
Fargo Bank  maintains  each  mortgage loan file in a separate file folder marked
with a unique  bar code to assure  loan-level  file  integrity  and to assist in
inventory  management.  Files are segregated by  transaction or investor.  Wells
Fargo Bank has been engaged in the mortgage  document  custody business for more
than 25 years.  Wells Fargo Bank maintains  document


                                      S-47


custody  facilities  in its  Minneapolis,  Minnesota  headquarters  and in three
regional offices located in Richfield,  Minnesota,  Irvine, California, and Salt
Lake City,  Utah.  As of June 30,  2006,  Wells  Fargo Bank  maintains  mortgage
custody  vaults in each of those  locations  with an aggregate  capacity of over
eleven million files.

      Wells Fargo Bank  serves or may have  served  within the past two years as
loan file  custodian  for  various  mortgage  loans  owned by the  Sponsor or an
affiliate  of the Sponsor  and  anticipates  that one or more of those  mortgage
loans may be included in the Trust.  The terms of any custodial  agreement under
which  those  services  are  provided  by  Wells  Fargo  are  customary  for the
mortgage-backed  securitization industry and provide for the delivery,  receipt,
review and safekeeping of mortgage loan files.

      The Trustee may appoint one or more  co-trustees  if  necessary  to comply
with the fiduciary requirements imposed by any jurisdiction in which a Mortgaged
Property is located. In the case of any appointment of a co-trustee, all rights,
powers,  duties and  obligations  conferred  or imposed upon the Trustee will be
conferred  or imposed  upon and  exercised  or  performed by the Trustee and the
co-trustee jointly,  unless the law of a jurisdiction prohibits the Trustee from
performing its duties under the Pooling and Servicing Agreement,  in which event
such rights,  powers, duties and obligations  (including the holding of title to
the  Trust  or any  portion  of the  Trust in any  such  jurisdiction)  shall be
exercised and performed by the co-trustee at the direction of the Trustee.

      See  "Description  of the  Agreements--Material  Terms of the  Pooling and
Servicing Agreements and Underlying Servicing  Agreements" in the prospectus for
more information about the Trustee and its obligations and rights (including its
right to indemnity and reimbursement in certain circumstances) under the Pooling
and Servicing Agreement.

                             THE CREDIT RISK MANAGER

      Clayton  Fixed Income  Services  Inc.  (formerly  known as The  Murrayhill
Company), a Colorado corporation,  will act as the Credit Risk Manager. In 1997,
the Credit  Risk  Manager  created  the  business  of  independent,  third-party
transaction  oversight for the fixed income industry.  The Credit Risk Manager's
credit risk management  portfolio  consists of more than $1 trillion in original
principal  balance across more than 400 MBS  transactions of various  collateral
types, including prime, Alt-A, subprime, scratch and dent, manufactured housing,
and HELOCs.  The Credit Risk Manager's  credit risk management  process enhances
transaction  performance through loan-level exception management and transaction
oversight.

      The  Credit  Risk  Manager  will not be  responsible  for  performing  any
servicing or  administrative  functions with respect to the Mortgage Loans,  but
rather will perform certain advisory functions in accordance with the provisions
of the credit risk  management  agreement  with the  Servicer.  These  oversight
functions are provided on an exception  management basis and aim to identify and
monitor  problems  in the  areas of  underwriting,  collateral,  reporting,  and
servicing of the Mortgage Loans, and may include the monitoring and/or making of
recommendations  to the Servicer  regarding  certain  Mortgage Loans. The Credit
Risk Manager's advice is made in the form of recommendation only, and the Credit
Risk Manager does not have the right to direct the Servicer to take any specific
course of action.  The  Servicer  may accept or reject a  recommendation  of the
Credit Risk Manager, in its sole discretion.

      The Credit Risk Manager will enter into a consulting  Agreement,  dated as
of the Closing Date,  with the Depositor to provide such consulting and advisory
services,  including  monthly  prepayment  analysis,  mortgage  insurance claims
analysis, realized loss analysis, delinquency review, bankruptcy, repayment, REO
and foreclosure analysis, delinquency trends, and periodic servicer reviews.

      The  Credit  Risk  Manager  will  enter  into  a  credit  risk  management
agreement,  dated as of the Closing  Date,  with the  Servicer.  The credit risk
management  agreement  requires  the Servicer to provide the Credit Risk Manager
certain  information  on the  Mortgage  Loans  and/or  access  to its  servicing
personnel.

      The Credit  Risk  Manager  will be  entitled  to receive  the Credit  Risk
Manager Fee until the termination of the Trust or until its removal by a vote of
at least 66-2/3% of the Certificateholders by Voting Rights.

                       THE POOLING AND SERVICING AGREEMENT

General

      The  Certificates  will be issued  pursuant to the  Pooling and  Servicing
Agreement,  dated as of October 1, 2006 (the "Pooling and Servicing Agreement"),
among the  Depositor,  the Servicer and the  Trustee.  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 thereof,  (iii) any Mortgaged  Properties acquired on
behalf of  Certificateholders  by foreclosure or by deed in lieu of foreclosure,
and any revenues received thereon,  (iv) the Cap Carryover Reserve Account,  (v)
the rights of the Trustee under all insurance policies required to be maintained
pursuant  to the  Pooling  and  Servicing  Agreement  and (vi) the rights of the
Depositor under the Option One Mortgage Loan Purchase Agreement and the Mortgage
Loan Purchase  Agreement.  The Offered  Certificates  will be  transferable  and
exchangeable  at the  corporate  trust  office of the  Trustee.  The  prospectus
contains important additional  information regarding the terms and conditions of
the Pooling and Servicing Agreement.

Assignment of the Mortgage Loans

      On the Closing Date the  Depositor  will transfer to the Trust Fund all of
its right, title and interest in and to each Mortgage Loan, the related mortgage
notes,  mortgages  and other  related  documents  (to the extent  required to be
delivered to the Sponsor under the Option One Mortgage Loan Purchase  Agreement,
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  transfers,   will  deliver  the  Certificates  to  the
Depositor.  Each Mortgage Loan  transferred to the Trust Fund will be identified
on a schedule (the "Mortgage Loan Schedule")  delivered to the Trustee  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 Interest Rate as well as other information.

      The  Pooling and  Servicing  Agreement  will  require  that the  Depositor
deliver   or  cause  to  be   delivered   to  the   Trustee  on  behalf  of  the
Certificateholders (or a 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
executed by the Sponsor or the Originator.

      Unless otherwise required by a Rating Agency,  assignments of the Mortgage
Loans to the Trustee (or its nominee) will not be recorded in any  jurisdiction,
but will be delivered  to the Trustee in  recordable  form,  so that they can be
recorded in the event  recordation is necessary in connection with the servicing
of a Mortgage  Loan. In addition,  assignments of the Mortgage Loans will not be
recorded  with  respect to any Mortgage  which has been  recorded in the name of
Mortgage Electronic  Registration Systems,  Inc. ("MERS") or its designee.  With
respect  to any  Mortgage  which  has been  recorded  in the name of MERS or its
designee,  no mortgage assignment in favor of the Trustee will be required to be
prepared  or  delivered.  Instead,  the  Servicer  will be  required to take all
actions  as are  necessary  to cause  the  Trust to be shown as the owner of the
related  Mortgage  Loan on the  records  of MERS for  purposes  of the system of
recording transfers of beneficial ownerships of mortgages maintained by MERS.

      Within 60 days  following  the Closing  Date the  Trustee  will review (or
cause a  custodian  to review)  the  Mortgage  Loans and the  Related  Documents
pursuant to the Pooling and  Servicing  Agreement  to  determine  if the Related
Documents  are in its  possession,  have not been  mutilated,  damaged  or torn,
relate to such  Mortgage  Loans and that  certain  information  set forth in the
Mortgage  Loan  Schedule  (such  as  balance  and  loan  identification  number)
accurately  reflects  information  set forth in the  Mortgage  File,  and if any
Mortgage  Loan or  Related  Document  is found  not to  conform  to this  review
criteria   and  such  defect  has  a  material   and   adverse   effect  on  the
Certificateholders  and is not  cured  within  120 days  following  notification
thereof  to the  Sponsor  (or  within 90 days of the  earlier  of the  Sponsor's
discovery  or receipt of  notification  if such defect  would cause the Mortgage
Loan not to be a "qualified  mortgage" for REMIC purposes),  the Sponsor will be
obligated to either (i) substitute for that Mortgage Loan an Eligible Substitute
Mortgage Loan; provided, 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


                                      S-49


substitution  will not disqualify any of the REMICs comprising the Trust Fund 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 Interest
Rate  through the end of the  calendar  month in which the purchase is effected,
plus  the  amount  of  any  unpaid  servicing  fees  (without  duplication)  and
unreimbursed Advances and Servicing Advances made by the Servicer.  If, however,
a Mortgage Loan is discovered to be defective in a manner that would cause it to
be a "defective  obligation" within the meaning of Treasury regulations relating
to REMICs, the Sponsor will be obligated to cure the defect or make the required
purchase  or  substitution  no  later  than 90 days  after  the  earlier  of its
discovery or receipt of notification  of the defect.  The Purchase Price will be
deposited  in  the  Collection  Account  on or  prior  to  the  next  succeeding
Determination  Date after such obligation  arises. The obligation of the Sponsor
to  repurchase or  substitute  for a Defective  Mortgage Loan is the sole remedy
regarding any defects in the Mortgage Loans and Related  Documents  available to
the Trustee or the Certificateholders.

      In connection  with the  substitution of an Eligible  Substitute  Mortgage
Loan,  the  Originator  or the Sponsor,  as the case may be, will be required to
deposit  in  the  Collection   Account  on  or  prior  to  the  next  succeeding
Determination  Date after such  obligation  arises an amount (the  "Substitution
Adjustment")  equal to the excess of the Purchase Price of the related Defective
Mortgage  Loan over the  Principal  Balance  (plus one month's  interest on such
balance) of such Eligible Substitute Mortgage Loan.

      An "Eligible  Substitute  Mortgage Loan" is a mortgage loan substituted by
the  Originator or the Sponsor,  as  applicable,  for a Defective  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
Defective  Mortgage Loan, an aggregate  Principal  Balance) not in excess of the
Principal  Balance  of the  Defective  Mortgage  Loan;  (ii) be of the same type
(fixed-rate or adjustable-rate)  and have a Mortgage Interest Rate not less than
the Mortgage  Interest Rate of the Defective  Mortgage Loan and not more than 2%
in excess of the Mortgage  Interest  Rate of such  Defective  Mortgage Loan and,
with respect to an  Adjustable-Rate  Mortgage  Loan,  have the same Index as the
Defective  Mortgage  Loan and have a Gross  Margin  equal to or greater than the
Defective  Mortgage Loan;  (iii) have a Credit Score not less than the Defective
Mortgage  Loan;  (iv) have a remaining  term to maturity  not more than one year
earlier  and not later than the  remaining  term to  maturity  of the  Defective
Mortgage  Loan;  (v) comply  with each  representation  and  warranty  as to the
Mortgage Loans set forth in the Option One Mortgage Loan Purchase  Agreement and
the  Mortgage  Loan  Purchase  Agreement  (deemed  to be made as of the  date of
substitution);  (vi) have a prepayment  charge at least equal to that prepayment
charge,  if any,  on the  Defective  Mortgage  Loan;  and (vii)  have a Combined
Loan-to-Value Ratio not greater than that of the Defective Mortgage Loan.

      Under the terms of the Option One Mortgage  Loan Purchase  Agreement,  the
Originator made certain  representations  and warranties  regarding the Mortgage
Loans,  which  will be  assigned  by the  Sponsor to the  Depositor,  and by the
Depositor  to the Trustee for the benefit of the  Certificateholders.  Within 90
days following its discovery of a breach of any  representation or warranty that
materially  or  adversely  affects  the  interests  of  Certificateholders  in a
Mortgage  Loan,  or receipt of notice of such  breach,  the  Originator  will be
obligated to cure such breach or purchase the  affected  Mortgage  Loan from the
Trust for the Purchase  Price (or, in certain  circumstances,  to  substitute an
Eligible Substitute Mortgage Loan). In addition to the foregoing,  if the breach
involves the  Originator's  representation  that the Mortgage Loan complies with
any and all  requirements  of  federal,  state or local law with  respect to the
origination of such Mortgage Loan, including,  without limitation,  usury, truth
in lending, real estate settlement procedures, consumer credit protection, equal
credit  opportunity,  predatory  and abusive  lending  laws or  disclosure  laws
applicable to the Mortgage Loans,  the Originator will be obligated to reimburse
the  Trust  for all costs or  damages  incurred  by the Trust as a result of the
violation of such representation (such amount, the "Reimbursement Amount").

      Pursuant to the terms of the Mortgage Loan Purchase Agreement, the Sponsor
will make to the Depositor (and the Depositor will assign to the Trustee for the
benefit of the  Certificateholders)  only certain  limited  representations  and
warranties  as of the Closing Date with  respect to the Mortgage  Loans such as:
(i) the accuracy of the Mortgage Loan Schedule; (ii) the payment and delinquency
status of each Mortgage  Loan;  (iii) 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;  (iv) each
Mortgage Loan complies with any and all  requirements  of any federal,  state or
local law with  respect to the  origination  of such  Mortgage  Loan  including,
without limitation,  usury, truth in lending, real estate settlement procedures,
consumer  credit  protection,  equal credit  opportunity,


                                      S-50


predatory and abusive lending laws or disclosure laws applicable to the Mortgage
Loans;  and (v) each Mortgaged  Property  securing the Mortgage Loans is in good
repair and is undamaged so as not to affect adversely the value of the Mortgaged
Property as security for the Mortgage Loan or the use for which the premises was
intended.  In the event of a breach of any such  representation or warranty that
does not  constitute  a breach of any  representation  or  warranty  made by the
Originator as described  above, the Sponsor will be obligated in the same matter
as the Originator to cure such breach or purchase the affected  Mortgage  Loans,
as  described  above.  In  addition  to  the  foregoing,  if  a  breach  of  the
representation set forth in clause (iv) occurs, the Sponsor will be obligated to
remit to the Trust any Reimbursement Amount which the Originator fails to pay.

      To the extent that any fact, condition or event with respect to a Mortgage
Loan  constitutes  a  breach  of  both  a  representation  and  warranty  of the
Originator under the Option One Mortgage Loan Purchase  Agreement,  and a breach
of a representation and warranty of the Sponsor under the Mortgage Loan Purchase
Agreement, then the only right or remedy of the Trustee or any Certificateholder
will be the Trustee's right to enforce the  obligations of the Originator  under
the Option One Mortgage  Loan  Purchase  Agreement,  and there will be no remedy
against the Sponsor for such breaches  (other than the  Sponsor's  obligation to
remit to the Trust any Reimbursement Amount which the Originator fails to pay).

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

Payments on Mortgage Loans; Deposits to Collection Account and Distribution
Account

      The  Servicer  will  establish  and  maintain or cause to be  maintained a
separate trust account (the "Collection Account") for the benefit of the holders
of the  Certificates.  The  Collection  Account will be an Eligible  Account (as
defined  below).  Upon  receipt  by the  Servicer  of  amounts in respect of the
Mortgage  Loans  (excluding  amounts  representing  the  Servicing  Fee or other
servicing  compensation,  reimbursement  for  Advances and  Servicing  Advances,
insurance  proceeds  to be applied to the  restoration  or repair of a Mortgaged
Property or similar  items),  the  Servicer  will be  required  to deposit  such
amounts in the  Collection  Account.  Amounts so  deposited  may be  invested in
certain investments acceptable to the Rating Agencies maturing no later than one
business  day  prior to the date on which  the  amount  on  deposit  therein  is
required to be deposited in the Distribution Account. The Trustee will establish
an account (the  "Distribution  Account")  into which the Trustee will  deposit,
upon receipt on the Servicer  Remittance Date preceding each Distribution  Date,
amounts withdrawn from the Collection Account and remitted to it by the Servicer
for distribution to Certificateholders on such Distribution Date and remitted to
it by the  Servicer.  The  Distribution  Account  will be an  Eligible  Account.
Amounts on deposit in the  Distribution  Account  may be  invested  in  eligible
investments  maturing  on or  before  the  business  day  prior  to the  related
Distribution  Date  unless  invested  in  investments  managed or advised by the
Trustee or an affiliate,  in which case the eligible  investments  may mature on
the related  Distribution  Date. The "Servicer  Remittance Date" with respect to
each  Distribution  Date will be the 20th day of the month of such  Distribution
Date (or if such day is not a business day, the preceding business day).

      An "Eligible  Account" is a  segregated  account that is (i) an account or
accounts maintained with a federal or state chartered depository  institution or
trust company the  short-term  unsecured  debt  obligations of which (or, in the
case  of a  depository  institution  or  trust  company  that  is the  principal
subsidiary of a holding  company,  the short-term  unsecured debt obligations of
such holding  company) are rated "A-1" (or the equivalent) by each of Standard &
Poor's,  a  division  of The  McGraw-Hill  Companies,  Inc.,  Moody's  Investors
Service,  Inc. and Fitch Ratings  (collectively,  the "Rating  Agencies") at the
time any amounts are held on deposit  therein,  (ii) an account or accounts  the
deposits in which are fully insured by the Federal Deposit Insurance Corporation
(to the limits established by such corporation), the uninsured deposits in which
account are  otherwise  secured such that, as evidenced by an opinion of counsel
delivered to the Trustee and to each Rating Agency, the Certificateholders  will
have a claim with  respect to the funds in such  account  or a  perfected  first
priority  security  interest against such collateral  (which shall be limited to
eligible  investments)  securing  such funds that is  superior  to claims of any
other  depositors  or creditors of the  depository  institution  with which such
account is  maintained,  (iii) a trust account or accounts  maintained  with the
trust  department  of a  federal  or  state  chartered  depository  institution,
national banking  association or trust company acting in its fiduciary  capacity
or (iv)  otherwise  acceptable  to  each  Rating  Agency  without  reduction  or
withdrawal of their then current  ratings of the  Certificates as evidenced by a
letter  from  each  Rating  Agency  to the  Trustee.  Eligible  investments  are
specified in the Pooling and Servicing  Agreement and are


                                      S-51


limited to investments  which meet the criteria of the Rating Agencies from time
to time as being  consistent  with their  then  current  ratings of the  Offered
Certificates.

Advances

      Subject to the  following  limitations,  the Servicer will be obligated to
advance or cause to be advanced on each  Servicer  Remittance  Date from its own
funds, or funds in the Collection Account that are not included in the Available
Funds for such  Distribution  Date, or a combination of both, an amount equal to
the aggregate of all payments of principal  and  interest,  net of the Servicing
Fee, that were due during the related  Collection  Period on the Mortgage  Loans
(other  than a  Balloon  Payment)  and that  were not  received  by the  related
Determination Date and, with respect to Balloon Loans, with respect to which the
Balloon Payment is not made when due, an assumed monthly payment that would have
been due on the related Due Date based on the  original  principal  amortization
schedule for such Balloon Loan (any such advance, an "Advance").

      Advances  with  respect to Mortgage  Loans are required to be made only to
the  extent  the  Servicer  deems  them  to be  recoverable  from  related  late
collections,  insurance proceeds, condemnation proceeds or liquidation proceeds.
The  purpose of making such  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,  however,  to make any Advances  with respect to
reductions  in the amount of the Monthly  Payments on the Mortgage  Loans due to
bankruptcy proceedings or the application of the Servicemembers Civil Relief Act
(the "Relief Act") or similar state laws. Subject to the recoverability standard
above,  the Servicer's  obligation to make Advances as to any Mortgage Loan will
continue  until such  Mortgage Loan is paid in full by the mortgagor or disposed
of by the Trust.

      All Advances will be reimbursable  to the Servicer from late  collections,
insurance  proceeds,  condemnation  proceeds and  liquidation  proceeds from the
Mortgage Loan as to which such unreimbursed  Advance was made. In addition,  any
Advances previously made in respect of any Mortgage Loan that the Servicer deems
to  be  nonrecoverable  from  related  late  collections,   insurance  proceeds,
condemnation  proceeds or liquidation proceeds may be reimbursed to the Servicer
out of general funds in the Collection Account prior to the distributions on the
Certificates. In addition, the Servicer may withdraw from the Collection Account
funds that were not included in Available  Funds for the preceding  Distribution
Date to reimburse itself for Advances previously made. In the event the Servicer
fails in its obligation to make any such Advance,  the Trustee,  in its capacity
as successor servicer, or a successor servicer appointed by the Trustee, will be
obligated to make any such  Advance,  to the extent  required in the Pooling and
Servicing Agreement.

      In the course of performing its servicing  obligations,  the Servicer will
pay all reasonable and customary  "out-of-pocket" costs and expenses incurred in
the performance of its servicing obligations, including, but not limited to, the
cost of (i) the  preservation,  restoration,  inspection  and  protection of the
Mortgaged Properties,  (ii) any enforcement or judicial  proceedings,  including
foreclosures  and (iii) the management and  liquidation of Mortgaged  Properties
acquired in satisfaction of the related  mortgage.  Each such  expenditure  will
constitute a "Servicing Advance."

      The Servicer's right to reimbursement for Servicing Advances is limited to
late collections on the related Mortgage Loan, including  liquidation  proceeds,
released mortgaged property proceeds, insurance proceeds,  condemnation proceeds
and such other  amounts the Servicer  may collect from the related  mortgagor or
otherwise  relating to the Mortgage  Loan in respect of which such  unreimbursed
amounts are owed,  unless such  amounts are deemed to be  nonrecoverable  by the
Servicer, in which event reimbursement will be made to the Servicer from general
funds in the Collection Account.

      The Pooling and Servicing  Agreement  may provide that the Servicer,  with
the consent of the parties to the Pooling  and  Servicing  Agreement,  may enter
into a facility with any person which  provides that such person (an  "Advancing
Person") may fund Advances and/or Servicing  Advances,  although no facility may
reduce or  otherwise  affect the  Servicer's  obligation  to fund such  Advances
and/or Servicing  Advances.  Any Advances and/or  Servicing  Advances made by an
Advancing  Person will be reimbursed to the Advancing  Person in the same manner
as reimbursements would be made to the Servicer.

Compensation and Payment of Expenses of the Servicer, the Trustee and the Credit
Risk Manager


                                      S-52


      The principal  compensation  to the Servicer will be the  "Servicing  Fee"
payable monthly by the Trust equal to 1/12th of the servicing fee rate set forth
in the table  below (the  "Servicing  Fee  Rate") in  respect  of its  servicing
activities for the Certificates.  The Servicing Fee will accrue on the aggregate
Principal Balance of the Mortgage Loans as of the first day of each month.

      The  principal  compensation  to be paid to the  Trustee in respect of its
obligations  under the  Pooling  and  Servicing  Agreement  will be  earnings on
eligible investments of funds on deposit in the Distribution Account.

      The Credit Risk  Manager  will be  entitled to receive a fee (the  "Credit
Risk Manager Fee") until the  termination of the Trust Fund or until its removal
by a vote of at least 66-2/3% of the  Certificateholders  by Voting Rights. This
fee will be paid monthly by the Trust equal to 1/12th of the credit risk manager
fee rate (the "Credit Risk Manager Fee Rate").  The Credit Risk Manager Fee will
accrue on the aggregate  Principal Balance of the Mortgage Loans as of the first
day of each month.

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


      Any co-trustee,  if applicable,  will be paid out of Available Funds prior
to any distributions to Certificateholders.

      The Servicing Fee for the Mortgage  Loans will be retained by the Servicer
out of the interest  payments on the Mortgage Loans,  prior to remittance to the
Trustee or distributions to Certificateholders. The Credit Risk Manager Fee will
be paid from the Interest  Remittance Amount (as described under "Description of
the  Certificates--Interest  Distributions")  to the Credit Risk Manager for its
services prior to any distributions to Certificateholders.

      In the event the  Trustee  succeeds  to the role of  Servicer,  it will be
entitled  to the  same  Servicing  Fee as the  predecessor  servicer  and if the
Trustee appoints a successor servicer under the Pooling and Servicing Agreement,
the Trustee may make such  arrangements  for the  compensation of such successor
out of the payments on the Mortgage Loans serviced by the  predecessor  Servicer
as it and such successor  shall agree,  not to exceed the Servicing Fee Rate. As
additional  servicing  compensation,  the  Servicer  is  entitled  to retain all
service-related  fees, including  assumption fees,  modification fees, extension
fees, bad check fees, late payment charges and Prepayment  Interest  Excess,  to
the extent collected from mortgagors, together with any interest or other income
earned on funds held in the  Collection  Account  and any escrow  accounts.  The
Servicer is obligated to offset any Prepayment Interest Shortfall resulting from
a principal  prepayment in full on the Mortgage Loans on any  Distribution  Date
(payments made by the Servicer in satisfaction of such obligation, "Compensating
Interest")  by an amount not in excess of the sum of its  Servicing  Fee and any
Prepayment Interest Excess for such Distribution Date. The Servicer is generally
obligated to pay expenses incurred by it in connection with its responsibilities
under the Pooling and  Servicing  Agreement,  unless these  expenses  constitute
Servicing  Advances as  described  above  under  "--Advances."  These  expenses,
including the fees of any subservicer hired by the Servicer, will be paid by the
Servicer out of its own funds, without reimbursement.

      "Prepayment Interest Excess" with respect to any Distribution Date will be
for each  Mortgage  Loan that was the subject of a principal  prepayment in full
during the portion of the related  Prepayment  Period beginning on the first day
of the  calendar  month in which  such  Distribution  Date  occurs  through  the
Determination Date of the calendar month in which such Distribution Date occurs,
an amount equal to interest (to the extent received) at the applicable  Mortgage
Interest Rate (net of the  Servicing  Fee Rate) on the amount of such  principal
prepayment  for the number of days  commencing  on the first day of the calendar
month in which  such  Distribution  Date  occurs and ending on the date on which
such prepayment is so applied.

      With respect to any Determination  Date and each Mortgage Loan as to which
a principal  prepayment  in full was  applied  during the portion of the related
Prepayment Period occurring in the prior calendar month or as to which a partial
prepayment  received  during  the  portion  of  the  related  Prepayment  Period
occurring  in the prior  calendar


                                      S-53


month is applied  during such prior calendar  month,  the  "Prepayment  Interest
Shortfall" is an amount equal to the interest at the Mortgage  Interest Rate for
such  Mortgage  Loan  (net of the  Servicing  Fee  Rate) on the  amount  of such
principal  prepayment for the number of days commencing on the date on which the
principal prepayment is applied and ending on the last day of the calendar month
in which applied.

      The Trustee is obligated to pay routine ongoing expenses incurred by it in
connection with its responsibilities  under the Pooling and Servicing Agreement.
Those  amounts  will be  paid  by the  Trustee  out of its  own  funds,  without
reimbursement.

      The   Depositor,   the   Servicer   and  the  Trustee   are   entitled  to
indemnification  and  reimbursement of certain expenses from the Trust under the
Pooling  and  Servicing  Agreement  as  discussed  in the  prospectus  under the
headings "The Depositor," "Description of the Agreements--Material  Terms of the
Pooling and Servicing  Agreements and Underlying  Servicing  Agreements--Certain
Matters  Regarding  Servicers and the Master  Servicer" and  "--Certain  Matters
Regarding the Trustee."

Optional Termination

      The  NIMS  Insurer,  if there  is a NIMS  Insurer,  or if there is no NIMS
Insurer, the majority holder of the Class CE Certificates or, if (i) such holder
is the  Sponsor or is  affiliated  with the Sponsor or (ii) there is no majority
holder  of the  Class CE  Certificates,  the  Servicer,  will  have the right to
purchase  all of the  Mortgage  Loans and REO  Properties  in the Trust Fund and
thereby effect the early  retirement of the  Certificates,  on any  Distribution
Date following the Distribution Date on which the aggregate Principal Balance of
such  Mortgage  Loans  and  REO  Properties  is 10% or  less  of the  sum of the
aggregate  Principal  Balance of the Mortgage  Loans as of the Cut-off Date. The
first  Distribution  Date on which such option could be exercised is referred to
herein as the  "Optional  Termination  Date." In the  event  that the  option is
exercised,  the  purchase  will be made at a  price  (the  "Termination  Price")
generally  equal to the sum of (x) par plus accrued  interest for each  Mortgage
Loan at the related Mortgage Interest Rate to but not including the first day of
the month in which such  purchase  price is  distributed  plus the amount of any
unpaid Servicing Fees and unreimbursed Advances and Servicing Advances,  and (y)
any Swap Termination  Payment owed to the Swap Provider pursuant to the Interest
Rate Swap Agreement. If any of the parties listed above is subject to regulation
by the OCC, the FDIC, the Federal  Reserve or the Office of Thrift  Supervision,
however,  such entity may not exercise  this option  unless the  aggregate  fair
market value of the Mortgage  Loans and REO  Properties is greater than or equal
to the Termination Price. In addition,  no option may be exercised until any due
and unpaid Reimbursement Amounts have been paid to the Trust. Proceeds from such
purchase  will be included in  Available  Funds and will be  distributed  to the
holders  of the  Certificates  in  accordance  with the  Pooling  and  Servicing
Agreement. Any such purchase of Mortgage Loans and REO Properties will result in
the early retirement of the Certificates.  Any such optional termination will be
permitted only pursuant to a "qualified  liquidation" as defined in Section 860F
of the Code.

      In  connection  with the  issuance of any net interest  margin  securities
secured  by all or a portion of the Class CE and Class P  Certificates,  a party
may agree to refrain  from  exercising  this option while those  securities  are
outstanding.

Optional Purchase of Defaulted Mortgage Loans

      As to any Mortgage Loan which is Delinquent in payment by 90 days or more,
the NIMS Insurer,  if there is a NIMS  Insurer,  or if there is no NIMS Insurer,
the majority holder of the Class CE  Certificates  or, if (i) such holder is the
Sponsor or is affiliated with the Sponsor or (ii) there is no majority holder of
the Class CE  Certificates,  the Servicer  may, at its option and in  accordance
with the terms of the Pooling and  Servicing  Agreement,  purchase such Mortgage
Loan from the  Trust  Fund at the  Purchase  Price for such  Mortgage  Loan.  In
addition,  the Servicer may only  exercise  such right if  delinquencies  on the
Mortgage  Loans exceed a specified  level set forth in the Pooling and Servicing
Agreement until such delinquencies are reduced to or below such specified level,
subject to certain  other  conditions  set forth in the  Pooling  and  Servicing
Agreement,  including  but not limited to the  condition  that the Servicer must
first purchase the Mortgage Loan that, as of the time of such purchase, has been
Delinquent for the greatest  period before  purchasing  Mortgage Loans that have
been Delinquent for lesser periods.

Events of Servicing Termination


                                      S-54


      Events of servicing termination will consist,  among other things, of: (i)
any failure by the  Servicer to deposit in the  Collection  Account the required
amounts or remit to the  Trustee  for  deposit in the  Distribution  Account any
payment which continues  unremedied for one business day after the first date on
which (x) the  Servicer has  knowledge of such failure or (y) written  notice of
such failure is given to the Servicer;  (ii) any failure of the Servicer to make
any Advance with respect to a Mortgage Loan or to cover any Prepayment  Interest
Shortfalls on Mortgage  Loans,  as described  herein,  which  failure  continues
unremedied  for one  business day after the first date on which (x) the Servicer
has knowledge of such failure or (y) written  notice of such failure is given to
the  Servicer;  (iii) any  failure by the  Servicer to observe or perform in any
material  respect any other of its  covenants or  agreements  in the Pooling and
Servicing Agreement, which continues unremedied for 30 days after the first date
on which (x) the Servicer has knowledge of such failure or (y) written notice of
such failure is given to the  Servicer (or a lesser  number of days set forth in
the  Pooling  and  Servicing  Agreement  in the case of failure  to perform  any
covenants or agreements  relating to the requirements of Regulation AB); or (iv)
insolvency,  readjustment  of debt,  marshalling  of assets and  liabilities  or
similar  proceedings,  and  certain  actions  by or on  behalf  of the  Servicer
indicating its insolvency or inability to pay its obligations.

Rights upon Event of Servicing Termination

      So long as an event of  servicing  termination  (as defined in the Pooling
and  Servicing  Agreement)  remains  unremedied,  the  Trustee  may,  and at the
direction of the holders of the Certificates evidencing not less than 51% of the
Voting Rights is required to, terminate all of the rights and obligations of the
Servicer in its  capacity as servicer  with respect to the  Mortgage  Loans,  as
provided in the Pooling and  Servicing  Agreement,  whereupon  the Trustee  will
succeed  to  (or   appoint  a   successor   servicer   to  assume)  all  of  the
responsibilities  and  duties  of  the  Servicer  pursuant  to the  Pooling  and
Servicing Agreement,  including the obligation to make any required Advances and
Servicing Advances. No assurance can be given that termination of the rights and
obligations of the Servicer under the Pooling and Servicing  Agreement would not
adversely  affect the  servicing of the related  Mortgage  Loans,  including the
delinquency experience of such Mortgage Loans.

Voting Rights

      With  respect  to any date of  determination,  the  percentage  of all the
Voting Rights allocated among holders of the Certificates  (other than the Class
CE,  Class  P,  Class R and  Class  R-X  Certificates)  will be 98% and  will be
allocated  among the classes of such  Certificates  in the  proportion  that the
aggregate  Certificate  Principal  Balance of all the Certificates of such class
then  outstanding  bear to the aggregate  Certificate  Principal  Balance of all
Certificates then outstanding. With respect to any date of determination,  1% of
all the Voting  Rights will be  allocated to the holders of each of the Class CE
and Class P Certificates. The Voting Rights allocated to a class of Certificates
will be  allocated  among all  holders of each such class in  proportion  to the
outstanding  certificate balances (or percentage interest) of such Certificates.
The Class R and Class R-X Certificates will not have any Voting Rights.

      No holder of an  Offered  Certificate,  solely by virtue of such  holder's
status  as a holder of an  Offered  Certificate,  will have any right  under the
Pooling and  Servicing  Agreement  to  institute  any  proceeding  with  respect
thereto,  unless such holder  previously has given to the Trustee written notice
of default  and unless the holders of  Certificates  having not less than 51% of
the  Voting  Rights  evidenced  by the  Certificates  so agree and have  offered
indemnity satisfactory to the Trustee.

Amendment

      The Pooling and Servicing  Agreement may be amended by the Depositor,  the
Servicer and the  Trustee,  with the consent of the NIMS insurer and without the
consent of the holders of the  Certificates,  for any of the  purposes set forth
under  "Description  of  the  Agreements--Material  Terms  of  the  Pooling  and
Servicing  Agreements and  Underlying  Servicing  Agreements--Amendment"  in the
prospectus or to provide for the rights of a NIMS Insurer,  if any, as described
under "--Rights of the NIMS Insurer under the Pooling and Servicing  Agreement."
In  addition,  the  Pooling  and  Servicing  Agreement  may  be  amended  by the
Depositor,  the  Servicer  and the  Trustee  and the  holders of a  majority  in
interest of any class of Certificates affected thereby for the purpose of adding
any provisions to or changing in any manner or eliminating any of the provisions
of the Pooling and Servicing  Agreement or of modifying in any manner the rights
of the holders of any class of  Certificates;  provided,  however,


                                      S-55


that no such  amendment may (i) reduce in any manner the amount of, or delay the
timing  of,  distributions  required  to be made on any  class  of  Certificates
without the consent of the holders of such  Certificates;  (ii) adversely affect
in any material respect the interests of the Swap Provider or the holders of any
class of  Certificates  in a manner other than as described in clause (i) above,
without the consent of the holders of such class evidencing percentage interests
aggregating not less than 51% of the Voting Rights represented by such class; or
(iii) reduce the aforesaid percentage of aggregate outstanding principal amounts
of  Certificates,  the  holders  of which are  required  to  consent to any such
amendment,  without  the  consent  of  the  holders  of all  such  Certificates.
Notwithstanding  the  foregoing,  the Trustee will not consent to any  amendment
that would result in the imposition of a tax on any REMIC  constituting  part of
the Trust Fund or cause any such REMIC to fail to qualify as a REMIC at any time
that the Certificates are outstanding.

Rights of the NIMS Insurer under the Pooling and Servicing Agreement

      After the Closing Date, a separate  trust may be  established to issue net
interest margin securities secured by all or a portion of the Class CE and Class
P  Certificates.  Those net interest  margin  securities may or may not have the
benefit of a financial guaranty  insurance policy. If a policy is obtained,  the
NIMS  Insurer that issues that policy will be a third party  beneficiary  of the
Pooling  and  Servicing  Agreement  and will have a number  of rights  under the
Pooling and Servicing Agreement, including the following:

   o  the right to consent to the Servicer's exercise of its discretion to waive
      assumption  fees,  late  payment  or other  charges in  connection  with a
      Mortgage  Loan or to arrange for the  extension  of Due Dates for payments
      due on a  mortgage  note for no more  than 125  days,  if the  waivers  or
      extensions  relate to more than 5% of the Mortgage Loans as of the Cut-off
      Date;

   o  the right to  direct  the  Trustee  to  terminate  all of the  rights  and
      obligations  of the  Servicer  under the Pooling and  Servicing  Agreement
      relating to the Trust Fund and the assets of the Trust Fund  following the
      occurrence  of an event of  servicing  termination  under the  Pooling and
      Servicing Agreement;

   o  the right to approve or reject the  appointment of any successor  servicer
      other than the Trustee, if the Servicer is required to be replaced and the

Allocation of Losses

      A "Realized Loss" is:

   o  as to any Liquidated  Mortgage Loan, its unpaid Principal Balance less the
      net proceeds from the  liquidation  of, and any insurance  proceeds  from,
      that Mortgage Loan and the related Mortgaged Property which are applied to
      the Principal Balance of that Mortgage Loan.

   o  as to any Mortgage Loan, a Deficient Valuation.

   o  as to any Mortgage  Loan, a reduction in its Principal  Balance  resulting
      from a Servicer Modification.

      A "Liquidated  Mortgage  Loan" is any defaulted  Mortgage Loan as to which
the Servicer has determined that all amounts which it expects to recover from or
on account of the Mortgage Loan have been recovered.

      A Realized Loss may result from the personal  bankruptcy of a mortgagor if
the  bankruptcy  court  establishes  the value of the  Mortgaged  Property at an
amount less than the then  outstanding  Principal  Balance of the Mortgage  Loan
secured by that  Mortgaged  Property and reduces the secured debt to such value.
In such case,  the Trust,  as the holder of the Mortgage  Loan,  would become an
unsecured  creditor  to the extent of the  difference  between  the  outstanding
Principal  Balance  of the  Mortgage  Loan and the  reduced  secured  debt  (the
difference, a "Deficient Valuation").


                                      S-70


      If a Mortgage Loan is in default, or if default is reasonably foreseeable,
the  Servicer  may  permit a  modification  of the  Mortgage  Loan to reduce its
Principal  Balance  and/or  extend its term to a term not longer than the latest
maturity  date of any other  Mortgage Loan (any such  modification,  a "Servicer
Modification").  Any such principal reduction will constitute a Realized Loss at
the time of the  reduction.  An  extension  of the term  will  not  result  in a
Realized Loss unless coupled with a principal reduction.

      Realized  Losses will, in effect,  be absorbed  through the application of
the  Monthly  Excess  Cashflow  Amount  and any Net Swap  Payment  from the Swap
Provider  to fund  the  deficiency,  as  well  as  through  a  reduction  in the
Overcollateralization Amount.

      If, after giving effect to the distribution of the Principal  Distribution
Amount and any Net Swap Payment from the Swap Provider on any Distribution  Date
and the increase of any Certificate Principal Balances as a result of Subsequent
Recoveries,  the aggregate  Certificate  Principal  Balance of the  Certificates
exceeds the Pool  Balance as of the end of the related  Collection  Period after
giving effect to principal  prepayments in the related  Prepayment  Period,  the
resulting  excess  (the  "Applied  Realized  Loss  Amount")  will  be  allocated
sequentially  to the Class B, 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,  until their
respective  Certificate  Principal Balances are reduced to zero. The Certificate
Principal Balances of the Senior Certificates will not be reduced by any Applied
Realized Loss Amounts; however, under certain loss scenarios,  there will not be
enough  interest  and  principal  on  the  Mortgage  Loans  to  pay  the  Senior
Certificates all interest and principal amounts to which they are entitled.  Any
reduction of a Certificate  Principal Balance will not be reversed or reinstated
(except in the case of Subsequent  Recoveries).  However, on future Distribution
Dates,  Certificateholders  of the related class may receive  payments up to the
Unpaid Realized Loss Amount for such class as described under  "--Application of
Monthly  Excess  Cashflow  Amounts" or from the Swap  Account,  according to the
priorities set forth under  "--Interest  Rate Swap Agreement,  the Swap Provider
and  the  Swap  Account"  below.  These  subsequent  payments  will  be  applied
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 and Class B Certificates.

Application of Monthly Excess Cashflow Amounts

      The weighted average Net Mortgage  Interest Rate for the Mortgage Loans is
generally  expected to be higher than the  weighted  average of the  Certificate
Interest Rates on the  Certificates,  thus  generating  certain excess  interest
collections  which,  in the  absence of losses,  will not be  necessary  to fund
interest  distributions  on  the  Certificates.   This  excess  interest  for  a
Collection Period,  together with interest on the  Overcollateralization  Amount
itself, is the "Monthly Excess Interest Amount."

      The "Net Mortgage  Interest Rate" for each Mortgage Loan is the applicable
Mortgage  Interest  Rate less the sum of (i) the Servicing Fee Rate and (ii) the
Credit Risk Manager Fee Rate.

      If  Realized  Losses  occur  that are not  covered by the  Monthly  Excess
Cashflow Amount and any Net Swap Payment from the Swap Provider,  these Realized
Losses  will  result in an  Overcollateralization  Deficiency  (since  they will
reduce the Pool Balance without giving rise to a corresponding  reduction of the
aggregate  Certificate  Principal  Balance of the  Certificates).  The  cashflow
priorities in this situation  increase the Extra Principal  Distribution  Amount
(subject to the availability of any Monthly Excess Cashflow Amount in subsequent
months) for the purpose of re-establishing the  Overcollateralization  Amount at
the then-required Targeted Overcollateralization Amount.

      On and after the Stepdown Date and assuming that a Trigger Event is not in
effect, the Targeted  Overcollateralization  Amount may be permitted to decrease
or  "stepdown."  If the  Targeted  Overcollateralization  Amount is permitted to
stepdown on a  Distribution  Date, the cashflow  priorities of this  transaction
permit a portion of the Principal  Remittance  Amount for that Distribution Date
not to be passed through as a distribution  of principal on the  Certificates on
that Distribution  Date. This has the effect of decelerating the amortization of
the Certificates relative to the Pool Balance, thereby reducing the actual level
of   the    Overcollateralization    Amount   to   the   new,   lower   Targeted
Overcollateralization  Amount.  This portion of the Principal  Remittance Amount
not distributed as principal on the  Certificates  therefore  releases a limited
portion of the overcollateralization from the Trust Fund.


                                      S-71


      On any  Distribution  Date, the sum of the Monthly Excess Interest Amount,
the  Overcollateralization  Release  Amount  and any  portion  of the  Principal
Distribution   Amount   (without   duplication)    remaining   after   principal
distributions on the Certificates is the "Monthly Excess Cashflow Amount," which
is  required to be applied in the  following  order of  priority  (the  "Monthly
Excess Cashflow Allocation") on that Distribution Date:

            (i) to the Senior  Certificates,  pro rata,  any  remaining  Accrued
      Certificate Interest for such classes for that Distribution Date;

            (ii) to the  Senior  Certificates,  pro  rata,  any  Interest  Carry
      Forward Amounts for such classes for that Distribution Date;

            (iii)  to  the  Class  M-1   Certificates,   any  remaining  Accrued
      Certificate Interest thereon for that Distribution Date;

            (iv) to the Class  M-1  Certificates,  any  Interest  Carry  Forward
      Amount thereon for that Distribution Date;

            (v) to the Class M-1  Certificates,  any  Class  M-1  Realized  Loss
      Amortization Amount for that Distribution Date;

      Amortization Amount for that Distribution Date;

allocated to that class,  (b) the  cumulative  amount of related  Realized  Loss
Amortization Amounts for that class for all prior Distribution Dates and (c) the
cumulative  amount of Unpaid Realized Loss Amounts  reimbursed to such class for
all prior Distribution Dates from the Supplemental Interest Trust.

Certificate Interest Rates

      Interest   for  each   Distribution   Date  will  accrue  on  the  Offered
Certificates  and the Class B Certificates  during the related  Interest Accrual
Period at a per annum rate (the "Certificate  Interest Rate") equal to the least
of (i) One-Month LIBOR plus the applicable  certificate  margin set forth in the
table beginning on page S-6, (ii) the applicable Maximum Rate Cap (the lesser of
(i) and (ii) for each  such  class,  the  "Pass-Through  Rate")  and  (iii)  the
applicable Cap for such  Distribution  Date. During each Interest Accrual Period
relating to the Distribution Dates after the Optional  Termination Date, each of
the certificate  margins will be "stepped-up" to the applicable margin set forth
in the table  beginning  on page S-6 if the  optional  termination  right is not
exercised.

Loans,  weighted on the basis of the Principal  Balances of the group 1 Mortgage
Loans  as of  the  first  day of  the  related  Collection  Period  minus  (b) a
percentage, expressed as a per annum rate (subject to an adjustment based on the
actual  number  of  days  elapsed  in  the  related  Interest  Accrual  Period),
calculated as a fraction,  the numerator of which is the sum of (i) any Net Swap
Payment owed to the Swap Provider and (ii) any Swap Termination  Payment owed to
the Swap Provider (other than any Swap Termination Payment resulting from a Swap
Provider  Trigger Event) and the  denominator of which is the Pool Balance as of
the first day of the related Collection Period.

Certificates  will be (a) a per annum rate (subject to  adjustment  based on the
actual number of days elapsed in the related  Interest  Accrual Period) equal to
the weighted average of the Net Mortgage Interest Rates for the group 2 Mortgage

Certificates  will be (a) a per annum rate (subject to  adjustment  based on the
actual number of days elapsed in the related  Interest  Accrual Period) equal to
the weighted average of the Net Mortgage Interest Rates for the group 3 Mortgage
Loans,  weighted on the basis of the Principal  Balances of the group 3 Mortgage
Loans  as of  the  first  day of  the  related  Collection  Period  minus  (b) a

Group Subordinate Amount.

      The "Pool Maximum Rate Cap" for any Distribution  Date and for the Class M
and Class B Certificates  will be a per annum rate equal to the weighted average
of the Group 1 Maximum  Rate Cap,  the Group 2 Maximum  Rate Cap and the Group 3
Maximum Rate Cap, weighted on the basis of the related Group Subordinate Amount.

      Each of the Group 1 Cap, the Group 2 Cap, the Group 3 Cap and the Pool Cap
are sometimes referred to in this free writing prospectus as a "Cap" and each of
the Group 1 Maximum  Rate Cap, the Group 2 Maximum Rate Cap, the Group 3 Maximum
Rate Cap and the Pool  Maximum Rate Cap are  sometimes  referred to in this free
writing prospectus as a "Maximum Rate Cap."

                                      S-76


      The "Group Subordinate Amount" for any Distribution Date and (i) the group
1 Mortgage Loans, will be equal to the excess of the aggregate Principal Balance
of the group 1  Mortgage  Loans as of the first  day of the  related  Collection
Period  over the  Certificate  Principal  Balance  of the  Group 1  Certificates
immediately  prior to that  Distribution  Date, (ii) the group 2 Mortgage Loans,
will be equal to the excess of the  aggregate  Principal  Balance of the group 2
Mortgage  Loans as of the first day of the  related  Collection  Period over the
Certificate  Principal Balance of the Group 2 Certificates  immediately prior to
that  Distribution  Date and (iii) the group 3 Mortgage Loans,  will be equal to
the excess of the aggregate  Principal  Balance of the group 3 Mortgage Loans as
of the first day of the related Collection Period over the aggregate Certificate
Principal  Balance  of the  Group  3  Certificates  immediately  prior  to  that
Distribution Date.

      If on any  Distribution  Date,  the Accrued  Certificate  Interest for any
Certificate  is based on the  applicable  Cap,  the  excess of (i) the amount of
interest  such  Certificate   would  have  been  entitled  to  receive  on  that
Distribution  Date  based on its  Pass-Through  Rate  over  (ii) the  amount  of
interest such Certificate  received on that  Distribution Date based on the Cap,
together  with the unpaid  portion of any such  excess  from prior  Distribution
Dates (and interest accrued thereon at the then applicable  Pass-Through Rate on
such Certificate)  will be the "Cap Carryover  Amount." Any Cap Carryover Amount
may be paid on the same or future  Distribution  Dates from  amounts  that would
otherwise be distributed on the Class CE  Certificates,  and then, to the extent
remaining  unpaid,  from amounts in the Swap Account,  as set forth herein under
"--Interest Rate Swap Agreement, the Swap Provider and the Swap Account." On the
Closing Date, the Trustee will establish the Cap Carryover Reserve Account ("Cap
Carryover Reserve Account") pursuant to the Pooling and Servicing Agreement from
which  distributions  of  Monthly  Excess  Cashflow  Amount  in  respect  of Cap
Carryover Amounts on the Offered  Certificates and the Class B Certificates will
be made. The Cap Carryover Reserve Account will be an asset of the Trust but not
of any REMIC.

      The Cap Carryover  Reserve  Account will be funded from amounts  otherwise
distributable to the Class CE Certificates  under clause (xxxiii) of the Monthly
Excess Cashflow Allocation. On each Distribution Date, amounts on deposit in the
Cap Carryover Reserve Account will be distributed, sequentially, as follows:

            first, concurrently,  to the Class A-1, Class A-2, Class A-3A, Class
      A-3B, Class A-3C and Class A-3D  Certificates,  pro rata (based on the Cap
      Carryover  Amount for each such class),  any Cap Carryover Amount for such
      class; and

            second, 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 and Class B
      Certificates, any Cap Carryover Amount for such class.

Interest Rate Swap Agreement, the Swap Provider and the Swap Account

The Interest Rate Swap Agreement

      On or before the Closing Date, the Supplemental  Interest Trust Trustee on
behalf of the  supplemental  interest  trust, a separate trust created under the
Pooling and Servicing  Agreement (the "Supplemental  Interest Trust") will enter
into an Interest Rate Swap Agreement with the Swap Provider. With respect to any
Distribution  Date prior to and  including  the  Distribution  Date in September
2011, the Supplemental Interest Trust Trustee will deposit into the Swap Account
certain amounts,  if any,  received from the Swap Provider and such amounts will
be distributed as described under "--The Swap Account." Neither the Supplemental
Interest Trust nor the Swap Account will be an asset of any REMIC.

      Under the Interest Rate Swap Agreement,  with respect to any  Distribution
Date occurring prior to and including the  Distribution  Date in September 2011,
the  Supplemental  Interest  Trust will be obligated to pay to the Swap Provider
from Available Funds a fixed amount equal to the product of (x) 5.0625%, (y) the
notional amount for that  Distribution Date set forth on the table in Appendix D
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,
and the Swap  Provider  will be  obligated to pay to the  Supplemental  Interest
Trust Trustee a floating  amount equal to the product of (x) one-month LIBOR (as
determined  pursuant to the  Interest  Rate Swap  Agreement),  (y) the  notional
amount for that Distribution Date set forth on the table in Appendix D 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,


                                      S-77


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 or  before  the  business  day  prior  to each
Distribution  Date  (each such net  payment,  a "Net Swap  Payment")  (a) by the
Supplemental  Interest Trust, to the Swap Provider, to the extent that the fixed
amount exceeds the  corresponding  floating amount, or (b) by the Swap Provider,
to the  Supplemental  Interest  Trust,  to the extent that the  floating  amount
exceeds the corresponding fixed amount.

      The initial  notional  amount for the Interest Rate Swap Agreement will be
approximately  $1,099,263,982.  The Interest Rate Swap  Agreement will terminate
immediately  after the  Distribution  Date in September  2011 unless  terminated
earlier upon the  occurrence of a Swap Default,  a Swap Early  Termination or an
Additional Termination Event.

      The  respective  obligations  of the Swap  Provider  and the  Supplemental
Interest Trust Trustee 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 ISDA Master  Agreement) has
occurred or been effectively designated by the Swap Provider or the Supplemental
Interest Trust Trustee under the Interest Rate Swap 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.  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.

      Upon any Swap Early  Termination,  the Supplemental  Interest Trust or the
Swap  Provider  may be liable to make a Swap  Termination  Payment  to the other
(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  Swap  Provider  under  the
remaining scheduled term of the Interest Rate Swap Agreement.  In the event that
the Supplemental  Interest Trust is required to make a Swap Termination  Payment
(other than a Swap  Termination  Payment  resulting from a Swap Provider Trigger
Event), that payment will be paid from the Supplemental  Interest Trust prior to
the related  Distribution Date, and, until paid in full, prior to any subsequent
Distribution Dates, prior to distributions to Certificateholders.

      Upon a Swap Early Termination, the Supplemental Interest Trust Trustee, at
the direction of the Depositor and with the consent of the NIMS Insurer, if any,
will seek a replacement swap provider to enter into a replacement  interest rate
swap agreement or similar  agreement.  To the extent the  Supplemental  Interest
Trust  receives  a  Swap  Termination  Payment  from  the  Swap  Provider,   the
Supplemental  Interest Trust Trustee will apply, as set forth in the Pooling and
Servicing Agreement, 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 Supplemental Interest Trust is required to pay a Swap Termination
Payment to the Swap Provider,  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 owing to the Swap Provider.

      Upon the  occurrence of a Downgrade  Provision,  the Swap Provider will be
required to (1) post collateral securing its obligations under the Interest Rate
Swap Agreement or (2) obtain a substitute Swap Provider acceptable to the Rating
Agencies,  that will  assume  the  obligations  of the Swap  Provider  under the
Interest Rate Swap Agreement or (3) obtain a guaranty of its obligations  from a
third  party  satisfactory  to the Rating  Agencies or (4)  establish  any other
arrangement satisfactory to the applicable Rating Agency or Rating Agencies.

      For  purposes  of  the  foregoing,  the  following  terms  will  have  the
respective meanings set forth below.


                                      S-78


      The  "Downgrade  Provisions"  of the Interest Rate Swap  Agreement will be
triggered if the Swap  Provider's  short-term or long-term  credit  ratings fall
below the levels specified in the Interest Rate Swap Agreement.

      "Events of Default" under the Interest Rate Swap Agreement  (each, a "Swap
Default")  include the following  standard events of default under the 2002 ISDA
Master  Agreement   published  by  the   International   Swaps  and  Derivatives
Association,  Inc.  (the "ISDA Master  Agreement"),  as modified by the Interest
Rate Swap Agreement:

   o  failure to pay or deliver,

   o  bankruptcy and insolvency events, and

   o  a merger by the Swap Provider  without an  assumption  of its  obligations
      under the Interest Rate Swap Agreement,

      as described in Sections  5(a)(i),  5(a)(vii) and 5(a)(viii)  (except with
respect to clause 2 thereof as it relates to the Supplemental Interest Trust) of
the ISDA Master Agreement.

      The "Swap  Account" means a segregated  trust account of the  Supplemental
Interest Trust in which payments owed to or received from the Swap Provider will
be deposited.

      A "Swap Early  Termination"  means the occurrence of an Early  Termination
Date under the Interest Rate Swap Agreement.

      A "Swap Provider Trigger Event" means 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)  or (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).

      The "Swap  Termination  Payment"  means the  amount,  if any,  owed by the
Supplemental Interest Trust or the Swap Provider upon a Swap Early Termination.

      A "Termination  Event" under the Interest Rate Swap Agreement  consists of
the following standard events under the ISDA Master Agreement:

   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  a 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 paying an additional amount on account of an indemnifiable  tax),
      and

   o  a tax event upon  merger  (solely  with  respect to the Swap  Provider  as
      merging party) (which generally relates to the Swap Provider's 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  paying  an
      additional  amount on  account  of an  indemnifiable  tax,  in each  case,
      resulting from a merger),

      as described in Section 5(b)(i), 5(b)(iii) and 5(b)(iv) of the ISDA Master
Agreement.

      In addition,  there are "Additional Termination Events" under the Interest
Rate Swap Agreement consisting of the following events:

   o  upon the  irrevocable  direction  to dissolve or otherwise  terminate  the
      Trust  following  which all assets of the Trust will be liquidated and the
      proceeds of such liquidation will be distributed to certificateholders,


                                      S-79


   o  upon the exercise of an optional termination,

   o  if the Pooling and Servicing Agreement or other transaction  documents are
      amended or modified without the prior written consent of the Swap Provider
      where written consent is required, and

   o  solely with respect to the Swap  Provider,  if the Swap Provider  fails to
      comply with the Downgrade Provisions.

      It may also be an  Additional  Termination  Event under the Interest  Rate
Swap  Agreement if the Depositor  determines at any time that it is required for
purpose  of  compliance  with Item  1115(b)(1)  or  (b)(2)  of the Asset  Backed
Securities  Regulation,  17  CFR  ss.229  ("Regulation  AB"),  to  disclose  any
financial data relating to the Swap Provider. If such determination is made, the
Swap  Provider  will be  required,  at its own  expense,  to (a)  provide to the
Depositor   the  required   financial   data,   (b)  subject  to  rating  agency
requirements,  select a successor  swap  provider  who will provide the required
financial data or (c) subject to rating agency requirements,  obtain a guarantee
from an affiliate, who will provide the required financial data, if provision of
such data would satisfy the  requirements of Regulation AB. If the Swap Provider
does not comply  with the  immediately  preceding  sentence,  then it will be an
Additional  Termination Event and the Swap Provider or the Supplemental Interest
Trust may be required to make a termination payment under the Interest Rate Swap
Agreement.

      The Supplemental  Interest Trust will not be required to make any gross-up
payments to the Swap Provider on account of any tax withholding.

      As of the date of this  free  writing  prospectus,  the  maximum  probable
exposure to the Swap  Provider  under the Interest  Rate Swap  Agreement is less
than 10% of the Pool Balance as of the Cut-off Date.

The Swap Account

      The Interest Rate Swap Agreement will be administered by the  Supplemental
Interest Trust Trustee pursuant to the Pooling and Servicing Agreement.  For any
Distribution  Date on which the Interest Rate Swap  Agreement is in effect,  the
Supplemental  Interest  Trust  Trustee will be required to deposit into the Swap
Account  established  by the  Supplemental  Interest  Trust  Trustee,  any  Swap
Termination  Payment (including a Swap


                                      S-80


Termination  Payment  resulting from a Swap Provider  Trigger Event) and any Net
Swap Payment.  Any Net Swap Payments and Swap  Termination  Payments (other than
any Swap  Termination  Payment  resulting  from a Swap Provider  Trigger  Event)
payable by the  Supplemental  Interest  Trust on a  Distribution  Date,  will be
deducted  from  interest  collections  on the Mortgage  Loans and, to the extent
interest  collections  on the  Mortgage  Loans  for such  Distribution  Date are
insufficient  to pay such amounts,  from  principal  collections on the Mortgage
Loans for such  Distribution  Date before any  distributions on the Certificates
for such Distribution Date.

      On  each  Distribution  Date,  to  the  extent  required,   following  the
distribution   of  the  Monthly  Excess   Cashflow  Amount  as  described  under
"--Application  of  Monthly  Excess  Cashflow  Amounts"  in  this  free  writing
prospectus and withdrawals  from the Cap Carryover  Reserve Account as described
under  "--Certificate  Interest Rates," the Supplemental  Interest Trust Trustee
will distribute amounts on deposit in the Swap Account 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 (other than a
Swap Termination  Payment  resulting from a Swap Provider Trigger Event) owed to
the  Swap  Provider  pursuant  to the  Interest  Rate  Swap  Agreement  for such
Distribution Date;

      third,  concurrently,  to each class of Class A Certificates,  the related
Accrued  Certificate  Interest  and  Interest  Carry  Forward  Amount  remaining
undistributed after the distributions of the Group 1 Interest Remittance Amount,
the Group 2 Interest  Remittance Amount, the Group 3 Interest  Remittance Amount

Calculation of One-Month LIBOR

      One-Month LIBOR for the first  Distribution Date will be determined on the
second  business  day  preceding  the  Closing  Date  and  for  each  subsequent
Distribution  Date will be  determined  on the second  business day prior to the
immediately preceding  Distribution Date (each such date, a "LIBOR Determination
Date"). With respect to each Distribution Date, "One-Month LIBOR" will equal the
interbank offered rate for one-month United States dollar deposits in the London
market as quoted on Telerate  Page 3750 as of 11:00 A.M.,  London  time,  on the
related  LIBOR  Determination  Date.  "Telerate  Page  3750"  means the  display
designated  as page 3750 on the  Reuters  Telerate  (or such  other  page as may
replace page 3750 on that service for the purpose of displaying London interbank
offered  rates of major  banks).  If such rate does not  appear on that page (or
such other page as may replace that page on that service,  or if such service is
no longer offered,  another service for displaying One-Month LIBOR or comparable
rates as may be selected by the Trustee),  the rate will be the  Reference  Bank
Rate. The "Reference  Bank Rate" will be determined on the basis of the rates at
which deposits in U.S.  Dollars are offered by the reference  banks (which shall
be three major banks that are engaged in  transactions  in the London  interbank
market,  selected by the Trustee) as of 11:00 A.M.,  London time, on the related
LIBOR  Determination  Date to prime banks in the London  interbank  market for a
period of one month in amounts  approximately equal to the aggregate Certificate
Principal Balance of the Offered Certificates and the Class B Certificates.  The
Trustee will request the principal  London office of each of the reference banks
to provide a quotation of its rate. If at least two quotations are provided, the
rate will be the arithmetic mean of the  quotations.  If on such date fewer than
two quotations are provided as requested,  the rate will be the arithmetic  mean
of the rates quoted by one or more major banks in New York City, selected by the
Trustee,  as of 11:00 A.M., New York City time, on such date for loans in United
States  dollars to leading  European  banks for a period of one month in amounts
approximately  equal  to the  aggregate  Certificate  Principal  Balance  of the
Offered  Certificates  and the Class B  Certificates.  If no  quotations  can be
obtained, the rate will be One-Month LIBOR for the prior Distribution Date.

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

                  YIELD, PREPAYMENT AND MATURITY CONSIDERATIONS

      The  yields  to  maturity  and  weighted  average  lives  of  the  Offered
Certificates  will  depend  upon,  among other  things,  the price at which such
Offered Certificates are purchased,  the amount and timing of principal payments
on the applicable  Mortgage Loans,  the allocation of Available Funds to various
classes  of   Offered   Certificates,   the  amount  and  timing  of   mortgagor
delinquencies  and  defaults  on the  applicable  Mortgage  Loans,  the  rate of
liquidations  and  Realized  Losses and the  allocation  of  Realized  Losses to
various classes of Offered  Certificates and the  relationship  between payments
made by the Trust and  payments,  if any,  made by the Swap  Provider  under the
Interest Rate Swap Agreement.

      The rate of payment of principal,  the aggregate  amount of  distributions
and the yield to maturity of the  Offered  Certificates  will be affected by the
rate of defaults  resulting in Realized Losses and by the severity and timing of
these  losses.  If  a  purchaser  of  an  Offered  Certificate   calculates  its
anticipated  yield  based on an assumed  rate of default  and amount of Realized
Losses  that is lower  than the  default  rate and  amount  of  losses  actually
incurred,  its actual yield to maturity will be lower than the yield calculated.
The timing of Realized  Losses will also affect an  investor's  actual  yield to
maturity,  even if the  average  rate of  defaults  and  severity  of losses 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.  There can be
no  assurance  as to the  delinquency,  foreclosure  or loss  experience  of the
Mortgage Loans. The Mortgage Loans may have a greater than normal risk of future
defaults and delinquencies,  as compared to newly originated,  high quality one-
to  four-family  residential  mortgage  loans of comparable  size and geographic
concentration  because the Mortgage Loans are of sub-prime  credit quality.  See
"Risk  Factors--Nature of sub-prime mortgage loans may increase risk of loss" in
this free  writing  prospectus  and  "Risk  Factors--Risks  Associated  with


                                      S-82


the Assets--Sub-Prime Mortgage Loans May Experience Greater Rates of Delinquency
and Foreclosure" in the prospectus.

      The rate of principal payments,  the aggregate amount of distributions and
the yields to maturity of the Offered  Certificates  will be related to the rate
and timing of payments of principal on the applicable  Mortgage Loans.  The rate
of  principal  payments  on the  Mortgage  Loans will in turn be affected by the
amortization  schedules  of the  Mortgage  Loans  and by the  rate of  principal
prepayments  (including for this purpose prepayments resulting from refinancing,
liquidations of the Mortgage Loans due to defaults,  casualties or condemnations
and repurchases by the Sponsor, the Originator or the Servicer). Because certain
of the Mortgage Loans contain prepayment charges, the rate of principal payments
may be less than the rate of principal payments for mortgage loans which did not
have  prepayment  charges.  The Mortgage Loans are subject to the  "due-on-sale"
provisions in the related  mortgage  notes.  See "Yield  Considerations"  in the
prospectus.

      Unscheduled  payments of principal  (whether  resulting from  prepayments,
liquidations,   casualties,  condemnations,   repurchases  due  to  breaches  of
representations  and  warranties,   or  purchase  in  connection  with  optional
termination) will result in distributions on the related Offered Certificates of
principal  amounts which would otherwise be distributed over the remaining terms
of the  Mortgage  Loans.  Since the rate of payment of principal on the Mortgage
Loans will depend on future events and a variety of other factors,  no assurance
can be given as to such rate or the rate of principal prepayments. The extent to
which the yield to maturity of a class of Offered Certificates may vary from the
anticipated  yield  will  depend  upon the degree to which such class of Offered
Certificates is purchased at a discount or premium,  and the degree to which the
timing of  payments  thereon  is  sensitive  to  prepayments,  liquidations  and
purchases of the applicable Mortgage Loans. Further, an investor should consider
the risk that, in the case of any Offered Certificate purchased at a discount, a
slower than anticipated rate of principal  payments  (including  prepayments) on
the  applicable  Mortgage Loans could result in an actual yield to such investor
that is lower  than  the  anticipated  yield  and,  in the  case of any  Offered
Certificate  purchased at a premium, a faster than anticipated rate of principal
payments on the  applicable  Mortgage  Loans could  result in an actual yield to
such investor that is lower than the anticipated yield.

      The  rate of  principal  payments  (including  prepayments)  on  pools  of
mortgage  loans  may vary  significantly  over time and may be  influenced  by a
variety  of  economic,  geographic  and  other  factors,  including  changes  in
mortgagors' housing needs, job transfers,  unemployment,  mortgagors' net equity
in the mortgaged properties and servicing  decisions.  In general, if prevailing
interest rates were to fall  significantly  below the Mortgage Interest Rates on
the Mortgage  Loans,  such Mortgage Loans could be subject to higher  prepayment
rates than if prevailing  interest rates were to remain at or above the Mortgage
Interest Rates on such Mortgage Loans. Conversely,  if prevailing interest rates
were to rise significantly, the rate of prepayments on such Mortgage Loans would
generally be expected to decrease.  As is the case with the Fixed-Rate  Mortgage
Loans,  the  Adjustable-Rate  Mortgage Loans may be subject to a greater rate of
principal  prepayments  in a low interest  rate  environment.  For  example,  if
prevailing interest rates were to fall, mortgagors with adjustable-rate mortgage
loans may be inclined to refinance their  adjustable-rate  mortgage loans with a
fixed-rate  loan to  "lock  in" a lower  interest  rate.  The  existence  of the
applicable  Periodic Rate Cap and Maximum Mortgage Interest Rate also may affect
the likelihood of prepayments resulting from refinancings.  No assurances can be
given as to the rate of  prepayments on the Mortgage Loans in stable or changing
interest rate environments.  In addition, the delinquency and loss experience of
the  Adjustable-Rate  Mortgage  Loans may  differ  from  that on the  Fixed-Rate
Mortgage Loans because the amount of the Monthly Payments on the Adjustable-Rate
Mortgage Loans are subject to adjustment on each  Adjustment  Date.  Further,  a
majority  of the  Adjustable-Rate  Mortgage  Loans will not have  their  initial
Adjustment   Date  for  two  to  five  years   after  their   origination.   The
Adjustable-Rate 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  Interest  Rates  on such
Adjustable-Rate  Mortgage  Loans as  borrowers  seek to avoid  changes  in their
Monthly Payments.

      The  weighted  average  life  and  yield  to  maturity  of each  class  of
Certificates  will also be influenced by the amount of Monthly  Excess  Cashflow
Amounts  generated  by the  Mortgage  Loans  and  applied  in  reduction  of the
Certificate Principal Balances of such Certificates. The level of Monthly Excess
Cashflow Amounts  available on any Distribution  Date to be applied in reduction
of the Certificate Principal Balances of the Certificates will be influenced by,
among other factors, (i) the  overcollateralization  level of the Mortgage Loans
at such time  (i.e.,  the  extent to which  interest  on the  Mortgage  Loans is
accruing on a higher Principal Balance than the aggregate


                                      S-83


Certificate  Principal  Balance of the  Certificates);  (ii) the delinquency and
default  experience of the Mortgage Loans;  and (iii) the level of the Index for
the  Adjustable-Rate  Mortgage  Loans.  To the extent  that  greater  amounts of
Monthly Excess Cashflow  Amounts are distributed in reduction of the Certificate
Principal Balance of a class of Certificates,  the weighted average life thereof
can be  expected  to  shorten.  No  assurance  can be given as to the  amount of
Monthly Excess Cashflow Amounts distributed at any time or in the aggregate.

      The Class M and Class B  Certificates  are not  expected  to  receive  any
principal  distributions  until at least the  Distribution  Date in October 2009
(unless the aggregate  Certificate  Principal Balance of the Senior Certificates
is reduced to zero prior thereto).  As a result,  the weighted  average lives of
the Class M and Class B  Certificates  will be longer  than  would have been the
case if principal  distributions were to be made on a pro rata basis. The longer
weighted  average  lives may  increase  the risk that an Applied  Realized  Loss
Amount  will  be  allocated  to one or  more  classes  of  Class  M and  Class B
Certificates.

      Option One generally will be required to repurchase from the Trust certain
Mortgage  Loans for which the first  scheduled  monthly  payment due after their
purchase  by the Sponsor  becomes 45 or more days  Delinquent.  Such  repurchase
obligation shall have the same effect on the holders of the Offered Certificates
as a  prepayment  on the  Mortgage  Loans.  See "Risk  Factors--There  are risks
involving  unpredictability  of  prepayments  and the effect of  prepayments  on
yields" in this free writing prospectus.

Weighted Average Lives

      The timing of changes in the rate of principal prepayments on the Mortgage
Loans may significantly  affect an investor's actual yield to maturity,  even if
the average rate of principal  prepayments  is consistent  with such  investor's
expectation.  In general,  the earlier a principal  prepayment  on the  Mortgage
Loans  occurs,  the  greater  the  effect  of such  principal  prepayment  on an
investor's  yield to maturity.  The effect on an  investor's  yield of principal
prepayments  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  may not be offset by a subsequent  like  decrease (or increase) in
the rate of principal prepayments.

      The projected  weighted average life of any class of Offered  Certificates
is the average amount of time that will elapse from the Closing Date, until each
dollar of principal is scheduled to be repaid to the  investors in such class of
Offered Certificates.  Because it is expected that there will be prepayments and
defaults on the Mortgage Loans, the actual weighted average lives of the classes
of Offered  Certificates  are expected to vary  substantially  from the weighted
average remaining terms to stated maturity of the Mortgage Loans as set forth in
the  tables in this free  writing  prospectus  under  "Summary  of Free  Writing
Prospectus."

      Prepayments  on  mortgage  loans  are  commonly  measured  relative  to  a
prepayment  model or standard.  The prepayment  models used in this free writing
prospectus  (the  "Prepayment  Assumptions")  are  based on an  assumed  rate of
prepayment each month of the then unpaid principal balance of three hypothetical
pools of mortgage loans similar to the Mortgage Loans.

      For the  Fixed-Rate  Mortgage  Loans,  the  Prepayment  Assumption  is the
"Fixed-Rate  Prepayment  Curve" or "FRM PPC," which assumes a prepayment rate of
2.30% CPR per annum of the then-outstanding  principal balance of a hypothetical
pool of  fixed-rate  mortgage  loans  in the  first  month  of the  life of such
mortgage loans and an additional  2.30% per annum in each month thereafter until
23% CPR is reached in the tenth month.  Beginning in the tenth month and in each
month  thereafter  during the life of such  mortgage  loans,  FRM PPC  assumes a
constant prepayment rate of 23.00% CPR per annum each month.

      For the Adjustable-Rate  Mortgage Loans, the Prepayment  Assumption is the
"Adjustable-Rate Prepayment Curve" or "ARM PPC," which assumes a prepayment rate
of 5% CPR per annum of the then-outstanding  principal balance of a hypothetical
pool of adjustable  rate  mortgage  loans in the first month of the life of such
mortgage  loans and an  additional  approximate  2.273%  per annum in each month
thereafter  until 30% CPR is  reached in the  twelfth  month.  Beginning  in the
twelfth month,  ARM PPC assumes a constant  prepayment rate of 30% CPR per annum
each  month  until  the  twenty-fifth   month  is  reached.   Beginning  in  the
twenty-fifth  month,  ARM PPC assumes a constant  prepayment rate of 60% CPR per
annum each month  until the  twenty-eighth  month is reached.  Beginning  in the
twenty-eighth  month  and in  each  month  thereafter  during  the  life of such
mortgage loans,


                                      S-84


ARM PPC  assumes a constant  prepayment  rate of 35% CPR per annum  each  month.
Notwithstanding  the foregoing,  CPR is capped at 90% with respect to all of the
decrement tables.

      "CPR"  represents a constant  assumed rate of  principal  prepayment  each
month relative to the  then-outstanding  principal balance of a pool of mortgage
loans for the life of such mortgage loans. No Prepayment  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.

      The decrement tables set forth in Appendix B were prepared on the basis of
the  Structuring  Assumptions in the following  paragraph.  There may be certain
differences  between the loan  characteristics  included in such assumptions and
the  characteristics of the actual Mortgage Loans. Any such discrepancy may have
an effect  upon the  percentages  of  original  Certificate  Principal  Balances
outstanding and weighted average lives of the Offered  Certificates set forth in
the decrement tables. In addition,  since the actual Mortgage Loans in the Trust
Fund will have  characteristics  that differ from those assumed in preparing the
table in Appendix C, the distributions of principal of the Offered  Certificates
may be made earlier or later than indicated in the tables.

      The  percentages and weighted  average lives in the decrement  tables were
determined  using  the  following  assumptions  collectively  (the  "Structuring
Assumptions"):  (i) the Mortgage Loans have the characteristics set forth in the
table in Appendix C, (ii) the closing date for the Offered  Certificates  occurs
on October 12, 2006 and the Offered  Certificates  are sold to investors on such
date,  (iii)  distributions on the Certificates are made on the 25th day of each
month  regardless of the day on which the  Distribution  Date  actually  occurs,
commencing in October 2006, in accordance with the allocation of Available Funds
set forth above under "Description of the Certificates," (iv) the Mortgage Loans
prepay in accordance with the Prepayment Assumptions indicated, (v) there are no
Prepayment Interest  Shortfalls,  (vi) neither the Sponsor nor the Originator is
required to substitute or repurchase  any of the Mortgage  Loans pursuant to the
Option  One  Mortgage  Loan  Purchase  Agreement,  the  Mortgage  Loan  Purchase
Agreement or the Pooling and Servicing Agreement and no optional  termination is
exercised  (except  with  respect to the entries  identified  by the row heading
"Weighted Avg. Life to Optional  Termination Date" in the tables in Appendix B),
(vii) the Targeted  Overcollateralization  Amount is set  initially as specified
herein and thereafter  decreases as described in the definition thereof,  (viii)
scheduled  payments  for  all  Mortgage  Loans  are  received  on the  Due  Date
commencing in October 2006,  the principal  portion of such payments is computed
prior to giving  effect to  prepayments  received in such month and there are no
losses  or  delinquencies  with  respect  to  such  Mortgage  Loans,  (ix)  such
prepayments  are received on the last day of each month  commencing in September
2006,  (x) the  Servicing  Fee Rate is 0.30% per annum for the first 10 calendar
months,  0.40% per annum for the 11th through 30th calendar months and 0.65% per
annum for all calendar months  thereafter,  and the Credit Risk Manager Fee Rate
is 0.015% per annum, (xi) One-Month LIBOR is at all times equal to 5.32%,  (xii)
the Certificate  Interest Rates for the Offered  Certificates  are calculated as
described  above under  "Description of the  Certificates--Certificate  Interest
Rates," (xiii) the Mortgage Interest Rate for each Adjustable-Rate Mortgage Loan
(which are  indicated as such in Appendix C with the  designation  ARM under the
column Interest Type) adjusts  semi-annually on its next Adjustment Date (and on
subsequent  Adjustment  Dates, if necessary) to equal the sum of (a) the assumed
level of the Index and (b) the respective  Gross Margin (this sum subject to the
applicable  Periodic  Rate Caps,  Minimum  Mortgage  Interest  Rates and Maximum
Mortgage   Interest   Rates),   (xiv)  the  Index  with   respect  each  of  the
Adjustable-Rate  Mortgage Loans is Six-Month  LIBOR and Six-Month LIBOR is equal
to  5.37%,  (xv) the  Class P  Certificates  have a zero  Certificate  Principal
Balance  and  (xvi)  the Net Swap  Payment  is  calculated  as  described  under
"Description  of  the  Certificates--Interest  Rate  Swap  Agreement,  the  Swap
Provider and the Swap Account" and no Swap Termination  Payment is made. Nothing
contained in the foregoing  assumptions  should be construed as a representation
that the Mortgage Loans will not experience delinquencies or losses.

      Based on the  foregoing  Structuring  Assumptions,  the  decrement  tables
indicate  the  projected  weighted  average  lives  of  each  class  of  Offered
Certificates and set forth the percentages of the original Certificate Principal
Balance of each such class  that  would be  outstanding  after each of the dates
shown at the indicated percentages of the applicable Prepayment Assumption.

                                 USE OF PROCEEDS

      The  Depositor  will  apply the net  proceeds  of the sale of the  Offered
Certificates  to the purchase  price of the Mortgage  Loans  transferred  to the
Trust. See "Method of Distribution" in this free writing prospectus.

                         FEDERAL INCOME TAX CONSEQUENCES

General

      The Pooling and Servicing  Agreement provides that designated  portions of
the Issuing Entity (exclusive of arrangements  intended to protect against basis
risk for certain of the certificates, the Interest Rate Swap Agreement, the Swap
Account,  the Supplemental  Interest Trust and the Cap Carryover Reserve Account
and certain other assets specified in the Pooling and Servicing  Agreement) will
comprise multiple REMICs.  Each REMIC will designate a single class of interests
as the  residual  interest in that REMIC.  Elections  will be made to treat each
REMIC as a REMIC  for  federal  income  tax  purposes.  Each  class  of  Offered
Certificates  (exclusive of the right to receive payments from the Cap Carryover
Reserve  Account and the  Supplemental  Interest Trust or the obligation to make
payments  to the  Supplemental  Interest  Trust),  the Class B, Class CE and the
Class P  Certificates  will  represent  beneficial  ownership  of REMIC  regular
interests.

      Upon the issuance of the Offered Certificates,  Hunton & Williams LLP will
deliver its opinion to the effect that, assuming compliance with the Pooling and
Servicing Agreement, for federal income tax purposes, each REMIC formed pursuant
to the  Pooling  and  Servicing  Agreement  will  qualify as a REMIC  within the
meaning of Section  860D of the Internal  Revenue Code of 1986,  as amended (the
"Code").

Taxation of Regular Interests

      For federal income tax reporting purposes, the regular interest portion of
the  classes of Offered  Certificates  may be treated as having been issued with
original issue discount ("OID"). The Prepayment  Assumption that will be used in
determining the rate of accrual of original issue  discount,  premium and market
discount,  if  any,  for  federal  income  tax  purposes  will be  based  on the
assumption that subsequent to the date of any  determination  the Mortgage Loans
will  prepay  at  a  constant   rate  of  100%  ARM  PPC  with  respect  to  the
Adjustable-Rate  Mortgage  Loans and 100% FRM PPC with respect to the Fixed-Rate
Mortgage Loans. No representation is made that the Mortgage Loans will prepay at
such   rate   or   at   any   other    rate.    See    "Federal    Income    Tax
Consequences--REMICs--Taxation  of Owners of Regular  Securities--Original Issue
Discount" in the prospectus.

      The IRS has issued regulations (the "OID Regulations") under Sections 1271
to 1275 of the Code  generally  addressing  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,  securities  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  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
manner 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.

      The Offered  Certificates  will  represent  beneficial  ownership of (i) a
REMIC  regular  interest  and (ii) the right to  receive  payments  from the Cap
Carryover   Reserve  Account  and  the  right  to  receive   payments  from  the
Supplemental  Interest  Trust in  respect  of the Cap  Carryover  Amount and the
obligation to make payments to the  Supplemental  Interest  Trust (the "Notional
Principal  Contract  Arrangement").  Holders of the  Offered  Certificates  must
allocate their basis between their regular interest and their Notional Principal
Contract Arrangement  component as set forth below under "--Taxation of Notional
Principal Contract Arrangement." The Cap Carryover Reserve Account, the Interest
Rate Swap Agreement,  the Swap Account and the  Supplemental  Interest Trust are
not assets of any REMIC created in this transaction.  The REMIC regular interest
corresponding  to an  Offered  Certificate  (the  "Regular  Interest")  will  be
entitled  to receive  interest  and  principal  payments at the times and in the
amounts equal to those made on the Offered  Certificate  to which it corresponds
except that (i) payments in respect of Cap Carryover Amounts will not be paid to
the  Regular  Interest,  (ii) the  maximum  interest  rate of the  corresponding
Regular Interest for the purposes of all  calculations  relating to such Regular
Interest will equal the weighted average of the Group 1 Cap, the Group 2 Cap and
the  Group  3 Cap,  weighted  on the  basis  of the  Principal  Balances  of the
applicable group of Mortgage Loans as of the first day of the related Collection
Period and computed for these  purposes by limiting the notional  balance of the
Interest Rate Swap Agreement to the aggregate


                                      S-86


Principal  Balance of the Mortgage Loans and (iii) any Swap Termination  Payment
will be treated as being first payable solely from the Excess Cashflow otherwise
distributable  to the Class CE Certificate and then from  distributions  made to
the Regular Interests,  which are then paid to the Swap Provider. As a result of
the foregoing, the amount of distributions on the Regular Interest corresponding
to an Offered  Certificate may exceed the actual amount of  distributions on the
Offered Certificate.

      The Regular  Interest of the Offered  Certificates  (but not the  Notional
Principal Contract Arrangement  components)  generally will be treated as assets
described in Section 7701(a)(19)(C) of the Code for a domestic building and loan
association and "real estate assets" under Section  856(c)(5)(B) of the Code for
a real estate  investment  trust (a  "REIT"),  in the same  proportion  that the
assets in the Issuing Entity would be so treated.  In addition,  interest on the
Regular Interests  generally will be treated as "interest on obligations secured
by mortgages on real  property"  under  Section  856(c)(3)(B)  of the Code for a
REIT, to the extent that the Regular Interest is treated as "real estate assets"
under   Section   856(c)(5)(B)   of  the   Code.   See   "Federal   Income   Tax
Consequences--REMICs--Characterization  of Investments  in REMIC  Securities" in
the prospectus. If more than 95% of the Regular Interests and income qualify for
these  treatments,  the  Regular  Interests  generally  will  qualify  for  such
treatments  in their  entirety  (exclusive  of the Notional  Principal  Contract
Arrangement  component).  However, no portion of an offered  certificateholder's
basis or income  allocable to a Notional  Principal  Contract  Arrangement  will
qualify for such treatment.  As a result, the Offered Certificates generally are
not  suitable  investments  for  inclusion  in  another  REMIC  and may not be a
suitable investment for a REIT.

Taxation of the Basis Risk Arrangements

      General. Each holder of an Offered Certificate will be treated for federal
income  tax  purposes  as having  entered  into a  notional  principal  contract
pursuant to its rights to receive payment with respect to Cap Carryover  Amounts
from the Cap Carryover  Reserve Account and the Supplemental  Interest Trust and
the obligation to make payments to the  Supplemental  Interest Trust on the date
it purchases its Certificates.

      In general,  the holders of the Offered  Certificates  must  allocate  the
price  they  pay for the  Offered  Certificates  between  the  Regular  Interest
component and the Notional  Principal  Contract  Arrangement  component based on
their relative fair market values.  To the extent rights to receive payments are
determined  to have a value on the  Closing  Date that is greater  than zero,  a
portion  of such  purchase  price will be  allocable  to such  rights,  and such
portion will be treated as a cap premium (the "Cap Premium") paid or received by
the  holders  of Offered  Certificates,  as  applicable.  A holder of an Offered
Certificate  will be required to amortize the Cap Premium  under a level payment
method as if the Cap Premium  represented the present value of a series of equal
payments  made  over  the life of the  applicable  Notional  Principal  Contract
Arrangement  (adjusted  to take into  account  decreases  in notional  principal
amount),  discounted at a rate equal to the rate used to determine the amount of
the Cap Premium  (or some other  reasonable  rate).  Prospective  purchasers  of
Offered  Certificates are encouraged to consult their own tax advisors regarding
the  appropriate  method of amortizing any Cap Premium.  The Notional  Principal
Contract Regulations treat a nonperiodic payment made under a notional principal
contract  as  a  loan  for  federal  income  tax  purposes  if  the  payment  is
"significant."  It is not known whether any Cap Premium would be treated in part
as a loan under the  regulations  governing  notional  principal  contracts (the
"Notional Principal Contract Regulations").  For information reporting purposes,
pursuant to the Pooling and  Servicing  Agreement,  the Trustee will assume that
the Notional  Principal  Contract  Arrangement will have a nominal value or such
other value as specified in the Pooling and  Servicing  Agreement.  The Notional
Principal  Contract  Arrangement is difficult to value, and the Internal Revenue
Service could assert that the value of a Notional Principal Contract Arrangement
as of the Closing Date is greater than the value used for information  reporting
purposes.  Prospective investors should consider the tax consequences to them if
the Internal  Revenue  Service were to assert a different value for the Notional
Principal Contract Arrangement.

      Under the Notional Principal  Contract  Regulations (i) all taxpayers must
recognize  periodic payments with respect to a notional principal contract under
the accrual method of accounting,  and (ii) any periodic payments received under
the applicable  Notional Principal  Contract  Arrangement must be netted against
payments,  if  any,  deemed  made  as a  result  of the Cap  Premiums  over  the
recipient's taxable year, rather than accounted for on a gross basis. Net income
or deduction  with respect to net payments under a notional  principal  contract
for a taxable year should constitute ordinary income or ordinary deduction.  The
IRS could  contend the amount is capital  gain or loss,  but such  treatment  is
unlikely,  at least in the absence of further  regulations.  Individuals  may be
limited in their


                                      S-87


ability to deduct any such net deduction and are encouraged to consult their tax
advisors prior to investing in the Offered Certificates.

      Any  payments  made to a  beneficial  owner of an Offered  Certificate  in
excess of the amounts  payable on the  corresponding  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 Cap Carryover  Amounts,  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  shall
represent a net  deduction for that year.  In addition,  any amounts  payable on
such  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 Cap  Carryover  Amounts for such taxable
year.  Although not clear, net income or a net deduction with respect to the Cap
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
payments and obligations under the Notional Principal Contract Arrangement.

      An offered  certificateholder's  ability to recognize a net deduction with
respect to the  Notional  Principal  Contract  Arrangement  component is limited
under  Sections  67 and 68 of the Code in the case of (i) estates and trusts and
(ii)  individuals  owning an  interest in such  component  directly or through a
"pass-through  entity" (other than in connection with such individual's trade or
business).  Pass-through entities include partnerships, S corporations,  grantor
trusts and  non-publicly  offered  regulated  investment  companies,  but do not
include estates, nongrantor trusts, cooperatives,  real estate investment trusts
and publicly offered regulated investment companies. Further, such a holder will
not be able to recognize a net  deduction  with  respect the Notional  Principal
Contract  Arrangement  component in computing the beneficial owner's alternative
minimum tax liability. Because a beneficial owner of an Offered Certificate will
be  required  to include  in income the amount  deemed to have been paid by such
owner pursuant to the Notional  Principal  Contract  Arrangement  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 the Notional  Principal  Contract
Arrangement would be subject to the limitations described above.

      It is  possible  that the right to  receive  payments  in  respect  of the
Notional Principal Contract  Arrangement could be treated as a partnership among
the holders of all of the  Certificates  subject to that  arrangement,  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  Cap  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.

      Any amount of  proceeds  from the sale,  redemption  or  retirement  of an
Offered  Certificate  that is  considered  to be  allocated  to  rights  under a
Notional  Principal  Contract  Arrangement  would be  considered a  "termination
payment" under the Notional  Principal Contract  Regulations.  It is anticipated
that the  Supplemental  Interest Trust Trustee will account for any  termination
payments  for  reporting  purposes in  accordance  with the  Notional  Principal
Contract Regulations, as described below.

      Termination  Payments.  Any amount of sales proceeds that is considered to
be allocated  to the selling  certificateholder's  rights  under the  applicable
Notional Principal Contract  Arrangement in connection with the sale or exchange
of an Offered Certificate would be considered a "termination  payment" under the
Notional Principal Contract Regulations allocable to that Offered Certificate. A
holder of an Offered  Certificate will have gain or loss from such a termination
of a  Notional  Principal  Contract  Arrangement  equal  to (i) any  termination
payment it received  or is deemed to have  received  minus (ii) the  unamortized
portion of any Cap Premium  paid (or deemed paid) by the  beneficial  owner upon
entering  into or  acquiring  its  interest  in a  Notional  Principal  Contract
Arrangement.


                                      S-88


      Gain or  loss  realized  upon  the  termination  of a  Notional  Principal
Contract  Arrangement  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.

REMIC Taxes and Reporting

      It is  not  anticipated  that  the  Issuing  Entity  will  engage  in  any
transactions that would subject it to the prohibited transactions tax as defined
in Section  860F(a)(2) of the Code, the  contributions tax as defined in Section
860G(d)  of the  Code or the tax on net  income  from  foreclosure  property  as
defined in Section 860G(c) of the Code.  However, in the event that any such tax
is imposed on the Issuing Entity,  such tax will be borne (i) by the Trustee, if
the Trustee has breached its obligations  with respect to REMIC compliance under
the Agreement,  (ii) the Servicer,  if the Servicer has breached its obligations
with respect to REMIC compliance under the Agreement, and (iii) otherwise by the
Issuing Entity, with a resulting reduction in amounts otherwise distributable to
Holders   of   the   Offered    Certificates.    See    "Description    of   the
Securities--General"  and "Federal Income Tax  Consequences--REMICs--Taxes  That
May Be Imposed on the REMIC Pool--Prohibited Transactions" in the prospectus.

      The responsibility for filing annual federal information returns and other
reports   will   be   borne   by  the   Trustee.   See   "Federal   Income   Tax
Consequences--REMICs--Taxes    That    May   Be    Imposed    on    the    REMIC
Pool--Administrative Matters" in the prospectus.

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

                              ERISA CONSIDERATIONS

      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 and/or a plan or other arrangement  subject to the
excise tax  provisions  set forth  under  Section  4975 of the Code (each of the
foregoing,  a "Plan") 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 plans described under that Section;
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 any of the  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 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.  However, such plans may
be subject to the  provisions of other  applicable  federal,  state or local law
("Similar Law") materially similar to the foregoing  provisions of ERISA and the
Code.  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 the 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 extended to Banc of America  Securities
LLC an administrative exemption (the "Exemption") from certain of the prohibited
transaction rules of ERISA and the related excise tax provisions of Section 4975
of the Code with respect to the initial purchase, the holding and the subsequent
resale by Plans of certificates  in pass-through  trusts that consist of certain
receivables,   loans  and  other   obligations  that  meet  the  conditions  and
requirements  of the  Exemption.  The Exemption can apply to  certificates  in a
pass-through  trust holding  mortgage loans,  and the Exemption may apply to the
Offered Certificates.


                                      S-89


      Among the conditions that must be satisfied for the Exemption to apply are
the following:

      (1) the acquisition of the  certificates by a Plan is on terms  (including
the price for the  certificates)  that are at least as  favorable to the Plan as
they would be in an arm's length transaction with an unrelated party;

      (2) the  certificates  acquired by the Plan have  received a rating at the
time  of  such  acquisition  that  is one of the  four  highest  generic  rating
categories  from  Standard & Poor's,  a division of The  McGraw-Hill  Companies,
Inc.,  Moody's  Investors  Service,  Inc. or Fitch  Ratings  (collectively,  the
"Exemption Rating Agencies");

      (3) the  trustee  must not be an  affiliate  of any  other  member  of the
Restricted Group (as defined below), other than an underwriter;

      (4) the sum of all payments  made to and retained by the  underwriters  in
connection with the  distribution of the  certificates  represents not more than
reasonable  compensation  for  underwriting  the  certificates;  the  sum of all
payments  made to and retained by the seller  pursuant to the  assignment of the
loans to the trust represents not more than the fair market value of such loans;
the sum of all payments made to and retained by the servicer represents not more
than  reasonable  compensation  for such person's  services  under the agreement
pursuant  to which the loans are  pooled  and  reimbursements  of such  person's
reasonable expenses in connection therewith; and

      (5) the Plan investing in the certificates is 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 (the "Act").

      The trust must also meet the following requirements:

            (i) the  corpus of the trust  must  consist  solely of assets of the
      type that 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 an Exemption  Rating  Agency for at least one year prior to
      the  acquisition of  certificates  by the Plan or with assets of the Plan;
      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 any acquisition of the  certificates by the Plan or with
      assets of the Plan.

      Moreover, the Exemption provides relief from certain self-dealing/conflict
of  interest  prohibited  transactions  that may occur  when the Plan  fiduciary
causes a Plan to acquire certificates in a trust holding receivables as to which
the  fiduciary  (or its  affiliate)  is an obligor  provided  that,  among other
requirements,  (i) in the case of an acquisition in connection  with the initial
issuance  of  certificates,  at  least  fifty  percent  (50%)  of each  class of
certificates in which Plans have invested is acquired by persons  independent of
the Restricted  Group; (ii) such fiduciary (or its affiliate) is an obligor with
respect to five percent (5%) or less of the fair market value of the obligations
contained in the trust;  (iii) a Plan's  investment in certificates of any class
does not exceed  twenty-five  percent (25%) of all of the  certificates  of that
class outstanding at the time of the acquisition; and (iv) immediately after the
acquisition,  no more than  twenty-five  percent (25%) of the assets of any Plan
with respect to which such person is a fiduciary  are  invested in  certificates
representing  an  interest  in one or  more  trusts  containing  assets  sold or
serviced by the same entity.  The Exemption does not apply to Plans sponsored by
any Underwriter,  the Trustee, the Servicer, the Swap Provider, the Cap Provider
any obligor  with  respect to  Mortgage  Loans  included  in the Issuing  Entity
constituting  more than five  percent  of the  aggregate  unamortized  principal
balance of the assets in the Issuing  Entity,  or any  affiliate of such parties
(the "Restricted Group").

      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


                                      S-90


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  exemptions  that  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  Department  of  Labor  Prohibited   Transaction  Class
Exemption 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 other  person  acting  on behalf of or using the
assets of 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.

      Plan  fiduciaries  should  consult  their  legal  counsel  concerning  the
availability  of,  and  scope of  relief  provided  by,  the  Exemption  and the
enumerated class exemptions.

      If any Offered  Certificate,  or any interest therein, is acquired or held
in violation of the provisions  discussed  above,  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
the preceding  paragraph shall indemnify to the extent permitted by law and hold
harmless the  Depositor,  the Trustee and the Servicer  from and against any and
all liabilities,  claims, costs or expenses incurred by such parties as a result
of such acquisition or holding.

      Prospective  Plan  investors  should  consult  with their  legal  advisors
concerning the impact of ERISA and the Exemption or any other exemption, and the
potential  consequences  in their  specific  circumstances,  prior to  making an
investment in the 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.

      For more information about ERISA considerations, see the information under
the heading "ERISA Considerations" in the prospectus.

                                LEGAL INVESTMENT

      The Offered Certificates will not constitute "mortgage related securities"
for  purposes of the  Secondary  Mortgage  Market  Enhancement  Act of 1984,  as
amended ("SMMEA").

      There may be restrictions on the ability of certain  investors,  including
depository  institutions,  either to  purchase  the Offered  Certificates  or to
purchase Offered  Certificates  representing more than a specified percentage of
the  investor's  assets.  Investors  are  encouraged  to consult their own legal
advisors in  determining  whether  and to what  extent the Offered  Certificates
constitute legal investments for such investors.  See "Legal  Investment" in the
Prospectus.

                          REPORTS TO CERTIFICATEHOLDERS

      The Trustee will prepare on a monthly basis a statement containing,  among
other things,  information  relating to principal and interest  distributions on
the  Certificates  and  the  status  of the  Mortgage  Pool  and  certain  other
information, as set forth in the Pooling and Servicing Agreement, required under
Item 1121 of Regulation AB


                                      S-91


as described under "Description of the Agreements--Material Terms of the Pooling
and  Servicing  Agreements  and  Underlying  Servicing   Agreements--Reports  to
Securityholders" in the prospectus.  In addition,  the Trustee and the Servicer,
and potentially  certain other parties as described in the Pooling and Servicing
Agreement,  will furnish to the Depositor and the Trustee,  as  applicable,  the
compliance  statements,  assessments and attestation  reports in accordance with
Item 1122 and Item 1123 of  Regulation  AB detailed  under  "Description  of the
Agreements--Material   Terms  of  the  Pooling  and  Servicing   Agreements  and
Underlying Servicing Agreements--Evidence as to Compliance" in the prospectus.

      Copies of these statements and reports will be filed on Form 10-D and Form
10-K with the SEC through its EDGAR system located at "http://www.sec.gov" under
the name of the Issuing  Entity for so long as the Issuing  Entity is subject to
the reporting requirement of the Securities Exchange Act of 1934, as amended.

      The Trustee  will make the  statement  described in the  prospectus  under
"Description  of the  Agreements--Material  Terms of the Pooling  and  Servicing
Agreements  and Underlying  Servicing  Agreements--Reports  to  Securityholders"
available each month to Certificateholders  and the other parties to the Pooling
and Servicing  Agreement via the Trustee's  internet website.  To the extent set
forth in the Pooling and  Servicing  Agreement,  the Trustee  will also make the
Periodic  Reports  described  in the  prospectus  under "Where You Can Find More
Information"  relating to the Issuing Entity available through its website.  The
Trustee's  internet  website  will  initially  be located at  "www.ctslink.com."
Assistance  in using the  website  can be  obtained  by  calling  the  Trustee's
customer  service  desk at (301)  815-6600.  Parties  that are unable to use the
website are  entitled to have a paper copy mailed to them at no charge via first
class mail by calling the customer service desk.

                                  LEGAL MATTERS

      The legality of the Offered  Certificates  and certain tax matters will be
passed upon for the Depositor and the  Underwriter by Hunton & Williams LLP, New
York, New York.

                                     RATINGS

      It is a condition  to the  issuance of the Offered  Certificates  that the
Certificates  receive at least the rating  set forth in the table  beginning  on
page S-6 of this free writing  prospectus from Standard & Poor's,  a division of
The  McGraw-Hill  Companies,  Inc.,  Moody's  Investors  Service,  Inc. or Fitch
Ratings.

      A  securities  rating  addresses  the  likelihood  of  the  receipt  by  a
Certificateholder  of distributions on the Mortgage Loans. The rating takes into
consideration  the  characteristics  of the Mortgage  Loans and the  structural,
legal and tax  aspects  associated  with the  certificates.  The  ratings on the
Offered  Certificates  do not,  however,  constitute  statements  regarding  the
likelihood  of the  payment  of any  Cap  Carryover  Amount,  the  frequency  of
prepayments  on the  Mortgage  Loans,  or the  possibility  that a holder  of an
Offered Certificate might realize a lower than anticipated yield.

      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.  In the event that the  ratings  initially  assigned to any of the
Offered  Certificates  by the Rating Agencies are  subsequently  lowered for any
reason,  no person or entity is obligated to provide any  additional  support or
credit enhancement with respect to such Offered Certificates.

      In addition,  the rating  agencies that assign the initial  ratings to the
Offered  Certificates  will  monitor  those  ratings  for so long as the Offered
Certificates remain outstanding.

         (i) multiplying the assumed net reduction, if any, in the Certificate
         Principal Balance on each Distribution Date of such class of
         Certificates by the number of years from the date of issuance of the
         Certificates to the related Distribution Date, (ii) summing the
         results, and (iii) dividing the sum by the aggregate amount of the
         assumed net reduction in the Certificate Principal Balance of such
         class of Certificates.

(1)      Rounded to the nearest whole percentage.
(2)      The weighted average life of any class of Certificates is determined by
         (i) multiplying the assumed net reduction, if any, in the Certificate
         Principal Balance on each Distribution Date of such class of
         Certificates by the number of years from the date of issuance of the
         Certificates to the related Distribution Date, (ii) summing the
         results, and (iii) dividing the sum by the aggregate amount of the
         assumed net reduction in the Certificate Principal Balance of such
         class of Certificates.

DESCRIPTION OF SECURITIES

      Each  series of  certificates  will be issued  pursuant  to a pooling  and
servicing  agreement  and  will  include  one or more  classes  representing  an
ownership  interest in a  segregated  pool of  mortgage  loans,  unsecured  home
improvement loans and/or  manufactured  housing  installment sales contracts and
other assets of the trust. If a series of securities  includes notes, such notes
will represent debt  obligations of the related trust fund formed  pursuant to a
deposit trust  agreement and will be secured by the assets of the trust pursuant
to an indenture.  A class of securities will be entitled, to the extent of funds
available,  to receive  distributions  from  collections on the related mortgage
loans and, to the extent specified in the related  prospectus  supplement,  from
any credit enhancements or cash flow agreements described in this prospectus.

      See "Description of the Securities" in this prospectus.

Interest Distributions

      For each series of securities, interest on each class of securities (other
than a class of  securities  entitled  to receive  only  principal)  will accrue
during  each  period  specified  in  the  prospectus   supplement  and  will  be
distributed  to the  holders  of the  related  classes  of  securities  on  each
distribution  date in  accordance  with the  particular  terms of each  class of
securities.  The terms of each  class of  securities  will be  described  in the
related prospectus supplement.

Securities" in this prospectus.

      For each series of securities,  principal payments (including prepayments)
on  the  related  mortgage  loans,   unsecured  home  improvement  loans  and/or
manufactured  housing installment sales contracts will be distributed to holders
of the related  securities  or  otherwise  applied as  described  in the related
prospectus  supplement on each distribution date.  Distributions in reduction of
principal  balance will be allocated among the classes of securities of a series
in the manner specified in the applicable prospectus supplement.

      See  "Description  of the  Securities--Distribution  of  Principal  of the
Securities" in this prospectus.

Denominations

      Each  class  of  securities  of a series  will be  issued  in the  minimum
denominations set forth in the related prospectus supplement.

Registration of the Securities

      The securities will be issued either:

      o     in book-entry form initially held through The Depository Trust
            Company in the United States, or Clearstream or Euroclear in Europe;
            or

      o     in fully registered, certificated form.

      See   "Description   of   the   Securities--General"   and   "--Book-Entry
Registration and Definitive Securities" in this prospectus.

ASSETS OF THE TRUST

      The trust  related to each series  will  consist  primarily  of any of the
following assets:

      o     a segregated pool of single family and/or multifamily mortgage loans
            which may include sub-prime mortgage loans;

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

                                       6





      o     manufactured housing installment sales contracts and installment
            loan agreements; and

      o     certain other property.

      You should refer to the applicable  prospectus  supplement for the precise
characteristics  or expected  characteristics of the assets and a description of
the other property, such as cash flow agreements or derivative  instruments,  if
any, included in a particular trust.

      See "Description of the Trust Funds" in this prospectus.

OPTIONAL TERMINATION OF THE TRUST

      The related prospectus  supplement may provide that the party specified in
the related prospectus supplement (which may be a securityholder) may

      o     repurchase all or part of the assets in the trust fund and thereby
            cause early retirement of some or all of the securities under the
            circumstances and in the manner specified in the related prospectus
            supplement; or

      o     auction all or part of the assets in the trust fund and thereby
            cause early retirement of the some or all of securities under the
            circumstances and in the manner specified in the related prospectus
            supplement.

      If an  election  is made  to  treat  the  issuing  entity  (or one or more
segregated  pools of assets of such issuing  entity) as one or more "real estate
mortgage  investment  conduits," any optional  termination or redemption will be
permitted only pursuant to a "qualified  liquidation,"  as defined under Section
860F of the Internal Revenue Code of 1986, as amended.

      See    "Description   of   the    Securities--Termination"    and   "Yield
Considerations" in this prospectus.

PREFUNDING ACCOUNT

      The related prospectus supplement may provide that the depositor deposit a
specified amount in a pre-funding account on the date the securities are issued.
In this case,  the  deposited  funds may only be used to acquire the  additional
assets  for the trust  during a set period  after the  initial  issuance  of the
securities.  Any amounts  remaining in the account at the end of the period will
be  distributed  as a  prepayment  of  principal  to the  holders of the related
securities.

      See  "Description  of  the  Trust   Funds--Prefunding   Account"  in  this
prospectus.

CREDIT ENHANCEMENT

      If so specified in the applicable prospectus supplement, the securities of
any series,  or any one or more  classes of a series,  may, in addition to or in
lieu  of  subordination,  be  entitled  to the  benefits  of one or  more of the
following types of credit enhancement:

o  overcollateralization                       o  excess interest

o  surety bond                                 o  cross-collateralization

o  financial guaranty insurance policy         o  reserve fund

o  spread account                              o  mortgage pool insurance policy

o  letter of credit                            o  limited guarantee

      Any  credit  support  will  be  described  in  detail  in  the  applicable
prospectus supplement.

      See "Description of Credit Support" in this prospectus.

                                       7





      In addition, if specified in the applicable prospectus supplement, amounts
received under one or more guaranteed investment  contracts,  swap agreements or
interest rate cap or floor agreements (also called yield maintenance agreements)
may also be used to  provide  credit  enhancement  for one or more  classes of a
series. See "Cash Flow Agreements" in this prospectus.

RATING OF SECURITIES

      The  securities  of any  series  will  not be  offered  pursuant  to  this
prospectus and a prospectus  supplement unless each offered security is rated in
one of the four highest rating categories by at least one nationally  recognized
statistical rating agency.

      o     A security rating is not a recommendation to buy, sell or hold the
            securities on any series and is subject to revision or withdrawal at
            any time by the assigning rating agency.

      o     Ratings do not address the effect of prepayments on the yield you
            may anticipate when you purchase your securities.

      See "Risk Factors--Risks Associated with the Securities--Ratings  Assigned
to the Securities Will Have Limitations" and "Ratings" in this prospectus.

TAX STATUS OF THE SECURITIES

      The securities of each series offered will be:

      o     regular interests and residual interests in a trust fund treated as
            a REMIC;

      o     interests in a trust fund treated as a grantor trust;

      o     interests in a trust fund treated as a partnership; or

      o     debt obligations secured by assets of a trust.

      For additional  information see "Federal Income Tax  Consequences" in this
prospectus and in the prospectus supplement.

ERISA CONSIDERATIONS

      If you are a  fiduciary  of any  employee  benefit  plan  or  arrangement,
including an individual  retirement account,  subject to the Employee Retirement
Income Security Act of 1974, as amended,  the Internal  Revenue Code of 1986, as
amended,  or any  federal,  state or local law which is  similar to ERISA or the
Code, you should  carefully review with your legal advisors whether the purchase
or holding of securities  could give rise to a transaction that is prohibited or
not otherwise permissible under ERISA, the Code or similar law.

      For additional  information see "ERISA  Considerations" in this prospectus
and in the prospectus supplement.

LEGAL INVESTMENT

      The applicable  prospectus  supplement  will specify  whether the class or
classes of securities offered will constitute  "mortgage related securities" for
purposes of the Secondary  Mortgage Market  Enhancement Act of 1984, as amended.
If  your  investment  activities  are  subject  to  legal  investment  laws  and
regulations,   regulatory   capital   requirements   or  review  by   regulatory
authorities,  then you may be  subject  to  restrictions  on  investment  in the
securities.  You  should  consult  your own legal  advisors  for  assistance  in
determining  the  suitability of the securities for you and the  consequences of
the purchase, ownership and sale of the securities.

      For additional information see "Legal Investment" in this prospectus and
in the prospectus supplement.

                                  RISK FACTORS

      You  should  consider,  among  other  things,  the  following  factors  in
connection  with  the  purchase  of  securities  as  well as the  specific  risk
discussed in the applicable prospectus supplement under "Risk Factors."

Risks Associated with the Securities

      Securities  May Not be Liquid.  The  liquidity of your  securities  may be
limited. You should consider that:

      o     a secondary market for the securities of any series may not develop,
            or if it does, it may not provide you with  liquidity of investment,
            or it may not continue for the life of the securities of any series;

      o     the prospectus  supplement for any series of securities may indicate
            that an underwriter  intends to establish a secondary  market in the
            securities of that series,  but no underwriter  will be obligated to
            do so; and

      o     the  securities  generally  will  not be  listed  on any  securities
            exchange.

      The  secondary  market  for  mortgage-backed  securities  has  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 (such as
securities  that receive only payments of principal or interest or  subordinated
securities), or that have been structured to meet the investment requirements of
limited categories of investors.  Consequently, you may not be able to sell your
securities  readily or at prices  that will enable you to realize  your  desired
yield.  The  market  values of the  securities  are likely to  fluctuate;  these
fluctuations may be significant and could result in significant losses to you.

      Limited  Source of Payments - No Recourse to  Depositor,  Sponsor,  Master
Servicer, Servicer or Trustee. Except for any related insurance policies and any
reserve fund or other external  credit  enhancement  described in the applicable
prospectus supplement:

      o     the  assets  included  in the  related  trust  fund will be the sole
            source of payments on the securities of a series;

      o     the  securities  of any series will not  represent an interest in or
            obligation of the depositor,  the sponsor, the master servicer,  the
            servicer,  the  trustee or any of their  affiliates,  except for any
            representing   parties'  limited  obligations  relating  to  certain
            breaches  of  its   representations   and   warranties  and  limited
            obligations   of  the  servicer   with  respect  to  its   servicing
            obligations; and

      o     neither  the  securities  of any series nor the  related  underlying
            assets will be guaranteed or insured by any  governmental  agency or
            instrumentality or any other entity.

      Consequently,  in the event that  payments on the assets  underlying  your
series of  securities  are  insufficient  or otherwise  unavailable  to make all
payments  required  on  your  securities,  there  will  be no  recourse  to  the
depositor, the sponsor, the master servicer, the servicer, the trustee or any of
their   affiliates  or,  except  as  specified  in  the  applicable   prospectus
supplement, any other entity.

      Credit Enhancement is Limited in Amount and Coverage. With respect to each
series of securities,  credit  enhancement may be provided in limited amounts to
cover certain types of losses on the underlying assets.  Credit enhancement will
be  provided  in one or  more  of the  forms  referred  to in  this  prospectus,
including,  but not limited to:  subordination of other classes of securities of
the     same      series;      excess      interest;      overcollateralization;
cross-collateralization;  a financial guaranty insurance policy; a reserve fund;
a surety bond; a spread account;  a mortgage pool insurance  policy; a letter of
credit; a limited guarantee; or any combination of the preceding types of credit
enhancement.  See  "Description  of  Credit  Support"  in  this  prospectus.  In
addition, if specified in the applicable prospectus supplement, amounts received
under  any  cash   flow   agreement   described   under   "Description   of  the

                                       9



Certificates--Cash   Flow  Agreements"  may  also  be  used  to  provide  credit
enhancement for one or more classes of certificates.

      Regardless of the form of credit enhancement provided:

      o     the amount of  coverage  will be limited in amount and in most cases
            will be subject to periodic  reduction in accordance with a schedule
            or formula; and

      o     the credit  enhancement may provide only very limited coverage as to
            certain  types of losses,  and may provide no coverage as to certain
            types of losses.

      None of the depositor, the sponsor, the master servicer, the servicer, the
trustee  or any of their  affiliates  will have any  obligation  to  replace  or
supplement any credit  enhancement,  or to take any other action to maintain any
rating of any class of securities.

      Rate of Prepayment on Assets May Adversely Affect Average Lives and Yields
on the  Securities.  The yield on the  securities  of each series will depend in
part on the rate of  principal  payment  on the assets  (including  prepayments,
liquidations due to defaults and asset repurchases). Such yield may be adversely
affected, depending upon whether a particular security is purchased at a premium
or a discount,  by a higher or lower than anticipated rate of prepayments on the
related assets. In particular:

      o     the yield on  principal-only  or  interest-only  securities  will be
            extremely  sensitive  to the  rate  of  prepayments  on the  related
            assets; and

      o     the  yield on  certain  classes  of  securities,  such as  companion
            securities,  may  be  relatively  more  sensitive  to  the  rate  of
            prepayments of specified assets than other classes of securities.

      The rate of  prepayments  on assets is  influenced by a number of factors,
including:

      o     the prevailing mortgage market interest rates;

      o     local and national economic conditions;

      o     homeowner mobility; and

      o     the ability of the borrower to obtain financing.

      If you are purchasing  securities at a discount,  and  specifically if you
are purchasing principal-only  securities,  you should consider the risk that if
principal  payments on the  mortgage  loans,  or, in the case of any ratio strip
securities,  the  related  mortgage  loans,  occur  at a rate  slower  than  you
expected, your yield will be lower than you expected.

      If you are  purchasing  securities  at a  premium,  or are  purchasing  an
interest-only  security, you should consider the risk that if principal payments
on the mortgage loans or, in the case of any interest-only  securities  entitled
to a portion of interest  paid on certain  mortgage  loans with higher  mortgage
interest rate,  those mortgage loans,  occur at a rate faster than you expected,
your yield may be lower than you expected.  If you are purchasing  interest-only
securities, you should consider the risk that a rapid rate of principal payments
on the  applicable  mortgage  loans could result in your failure to recover your
initial investment.

      If you are purchasing  any inverse  floating rate  securities,  you should
also consider the risk that a high rate of the applicable  index may result in a
lower actual yield than you expected or a negative  yield.  In  particular,  you
should  consider the risk that high constant  rates of the  applicable  index or
high constant  prepayment  rates on the mortgage loans may result in the failure
to recover your initial investment.

                                       10



      Timing  of  Prepayments  on the  Mortgage  Loans May  Result  in  Interest
Shortfalls  on the  Securities.  When a mortgage  loan is  prepaid in full,  the
mortgagor  pays interest on the amount  prepaid only to the date of  prepayment.
Liquidation  proceeds and amounts received in settlement of insurance claims are
also likely to include interest only to the time of payment or settlement.  When
a mortgage loan is prepaid in full or in part, an interest  shortfall may result
depending on the timing of the receipt of the  prepayment and the timing of when
those prepayments are passed through to  securityholders.  To partially mitigate
this reduction in yield,  the pooling  agreement,  indenture  and/or  underlying
servicing  agreements  relating to a series may provide, to the extent specified
in the applicable prospectus  supplement,  that for specified types of principal
prepayments  received,  the applicable  servicer or the master  servicer will be
obligated,  on or before each  distribution  date, to pay an amount equal to the
lesser of (i) the aggregate  interest shortfall with respect to the distribution
date resulting from those principal  prepayments by mortgagors and (ii) all or a
portion of the servicer's or the master  servicer's,  as  applicable,  servicing
compensation for the distribution date as specified in the applicable prospectus
supplement  or  other   mechanisms   specified  in  the  applicable   prospectus
supplement.  To the extent  these  shortfalls  from the  mortgage  loans are not
covered by the amount of compensating  interest or other mechanisms specified in
the applicable prospectus  supplement,  they will be allocated among the classes
of  interest  bearing   securities  as  described  in  the  related   prospectus
supplement.  No comparable  interest  shortfall coverage will be provided by the
servicer or the master  servicer  with respect to  liquidations  of any mortgage
loans. Any interest shortfall arising from liquidations will be covered by means
of the subordination of the rights of subordinated  securityholders or any other
credit support arrangements described in this prospectus.

      Ratings  Assigned to the  Securities  Will Have  Limitations.  The ratings
assigned to your securities will not:

      o     assess the likelihood that principal  prepayments  (including  those
            caused by defaults) on the related  assets will be made,  the degree
            to  which  the  rate of such  prepayments  might  differ  from  that
            originally   anticipated   or  the   likelihood  of  early  optional
            termination or redemption of the series of securities; and

      o     address the  possibility  that  prepayments at higher or lower rates
            than   anticipated  by  an  investor  may  cause  such  investor  to
            experience  a lower  than  anticipated  yield  or  that an  investor
            purchasing a security at a significant  premium might fail to recoup
            its initial investment under certain prepayment scenarios.

      In addition,  the ratings of any series of  securities  by any  applicable
rating agency may be lowered  following the initial  issuance of the securities.
The lowering of a rating on a series or class of securities may adversely affect
the market value of such securities and the liquidity of such  securities.  None
of the  depositor,  the  sponsor  or any  of  their  affiliates  will  have  any
obligation to maintain any rating of any series of securities.

      Book-Entry System for Certain Classes of Securities May Decrease Liquidity
and Delay Payment.  Since  transactions in the classes of securities of a Series
issued in  book-entry  form can be effected  only through The  Depository  Trust
Company,   Clearstream,   Euroclear,   participating   organizations,   indirect
participants and certain banks:

      o     you may experience  delays in your receipt of payments on book entry
            securities because  distributions will be made by the trustee,  or a
            paying agent on behalf of the trustee, to Cede & Co., as nominee for
            The Depository Trust Company, rather than directly to you;

      o     your ability to pledge such  securities  to persons or entities that
            do not participate in The Depository  Trust Company,  Clearstream or
            Euroclear may be limited due to the lack of a physical  certificate;
            and

      o     you may experience  delays in your receipt of payments on book-entry
            securities  in the event of  misapplication  of payments by DTC, DTC
            participants   or  indirect  DTC   participants   or  bankruptcy  or
            insolvency  of those  entities and your  recourse will be limited to
            your remedies against those entities.

      See "Description of the Securities--Book-Entry Registration and Definitive
Securities" in this prospectus.

      Risk of Loss May Be  Greater  on  Subordinated  Securities.  The rights of
holders of subordinated securities will be subordinate:

                                       11



      o     to the rights of the servicer and any master servicer (to the extent
            of their  servicing fees,  including any unpaid  servicing fees, and
            reimbursement  for certain  unreimbursed  advances and  unreimbursed
            liquidation expenses); and

      o     the  holders of senior  securities  to the extent  described  in the
            related prospectus supplement.

      As a result of the foregoing,  investors must be prepared to bear the risk
that they may be subject to delays in payment and may not recover  their initial
investments in the subordinated securities.  See "Description of Credit Support"
in this prospectus.

      The yields on the  subordinated  securities may be extremely  sensitive to
the loss experience of the related assets and the timing of any such losses.  If
the actual rate and amount of losses  experienced  by the assets exceed the rate
and amount of such losses  assumed by an investor,  the yield to maturity on the
subordinated securities may be lower than anticipated.

      Special  Powers  of the  FDIC in the  Event of  Insolvency  of the Bank of
America,  National Association,  as Sponsor, Could Delay or Reduce Distributions
on the Securities. If specified in the related prospectus supplement, the assets
may be acquired by Bank of America,  National  Association,  as sponsor. Bank of
America,  National  Association is a national bank whose deposits are insured to
the  applicable  limits by the FDIC.  If Bank of America,  National  Association
becomes  insolvent,  is in an unsound  condition or engages in violations of its
bylaws or regulations  applicable to it or if similar  circumstances  occur, the
FDIC could act as conservator and, if a receiver were appointed,  would act as a
receiver for it. As receiver, the FDIC would have broad powers to:

      o     require the trust,  as assignee of the  depositor,  to go through an
            administrative  claims procedure to establish its rights to payments
            collected on the assets; or

      o     request a stay of  proceedings  to  liquidate  claims  or  otherwise
            enforce  contractual  and legal  remedies  against  Bank of America,
            National Association.

      If the  FDIC  were to take  any of  those  actions,  distributions  on the
securities could be delayed or reduced.

      By  statute,  the FDIC as  conservator  or  receiver  of Bank of  America,
National  Association  is  authorized  to repudiate  any  "contract"  of Bank of
America,  National  Association  upon  payment  of "actual  direct  compensatory
damages."  This  authority  may be  interpreted  by the  FDIC  to  permit  it to
repudiate a transfer of mortgage loans by Bank of America,  National Association
to the depositor. Under an FDIC regulation,  however, the FDIC as conservator or
receiver  of  a  bank  has  stated  that  it  will  not   reclaim,   recover  or
recharacterize  a bank's  transfer  of  financial  assets in  connection  with a
securitization or participation, provided that the transfer meets all conditions
for sale accounting  treatment under generally accepted  accounting  principles,
other than the "legal  isolation"  condition as it applies to  institutions  for
which  the  FDIC may be  appointed  as  conservator  or  receiver,  was made for
adequate  consideration  and was not  made  fraudulently,  in  contemplation  of
insolvency,  or with the  intent to  hinder,  delay or  defraud  the bank or its
creditors.  For purposes of the FDIC regulation,  the term securitization means,
as relevant,  the issuance by a special  purpose entity of beneficial  interests
the most  senior  class of which at time of issuance is rated in one of the four
highest  categories  assigned to long-term  debt or in an equivalent  short-term
category  (within  either of which  there may be  sub-categories  or  gradations
indicating relative standing) by one or more nationally  recognized  statistical
rating  organizations.  A  special  purpose  entity,  as the term is used in the
regulation,  means a trust,  corporation,  or other entity demonstrably distinct
from the insured  depository  institution that is primarily engaged in acquiring
and  holding (or  transferring  to another  special  purpose  entity)  financial
assets, and in activities related or incidental to these actions,  in connection
with the issuance by the special  purpose entity (or by another  special purpose
entity that acquires  financial  assets  directly or indirectly from the special
purpose  entity) of beneficial  interests.  Any  transactions  involving Bank of
America, National Association as sponsor contemplated by this prospectus and the
related  prospectus  supplement  will be structured so that this FDIC regulation
should  apply to the  transfer  of the  assets  from Bank of  America,  National
Association to the depositor.

      If a condition  required under the FDIC regulation,  or other statutory or
regulatory  requirement  applicable to the  transaction,  were found not to have
been  satisfied,  the FDIC as  conservator or receiver might refuse to recognize

                                       12



Bank of America, National Association's transfer of the assets to the depositor.
In that event the depositor could be limited to seeking  recovery based upon its
security  interest  in the  assets.  The  FDIC's  statutory  authority  has been
interpreted  by the FDIC and at least one court to permit the  repudiation  of a
security interest upon payment of actual direct compensatory damages measured as
of the date of  conservatorship  or  receivership.  These damages do not include
damages for lost profits or  opportunity,  and no damages  would be paid for the
period  between  the date of  conservatorship  or  receivership  and the date of
repudiation.  The FDIC could delay its  decision  whether to  recognize  Bank of
America,  National  Association's transfer of the assets for a reasonable period
following  its  appointment  as  conservator  or  receiver  for Bank of America,
National  Association.  If the FDIC were to refuse to recognize Bank of America,
National  Association's  transfer  of the assets,  distributions  on the related
securities could be delayed or reduced.

      Insolvency  of the Depositor  May Delay or Reduce  Collections  on Assets.
Neither the United  States  Bankruptcy  Code nor similar  applicable  state laws
prohibit  the  depositor  from filing a voluntary  application  for relief under
these laws.  However,  the transactions  contemplated by this prospectus and the
related  prospectus  supplement  will be  structured  so that the  voluntary  or
involuntary application for relief under the bankruptcy laws by the depositor is
unlikely.  The  depositor  is  a  separate,   limited  purpose  subsidiary,  the
certificate of incorporation of which contains  limitations on the nature of the
depositor's  business,  including  the  ability  to incur  debt  other than debt
associated  with  the  transactions   contemplated  by  this   prospectus,   and
restrictions  on  the  ability  of  the  depositor  to  commence   voluntary  or
involuntary  cases or  proceedings  under  bankruptcy  laws  without  the  prior
unanimous  affirmative  vote of all its directors  (who are required to consider
the  interests  of the  depositor's  creditors,  in addition to the  depositor's
stockholders  in  connection  the filing of a voluntary  application  for relief
under applicable  insolvency laws).  Further,  the transfer of the assets to the
related  trust will be  structured  so that the  trustee  has no recourse to the
depositor.

      If the  depositor  were to become the  subject of a  proceeding  under the
bankruptcy laws, a court could conclude that the transfer of the assets from the
depositor to the trust should not be characterized as an absolute transfer,  and
accordingly,  that the  assets  should be  included  as part of the  depositor's
estate.  Under these  circumstances,  the bankruptcy  proceeding  could delay or
reduce  distributions on the securities.  In addition,  a bankruptcy  proceeding
could result in the temporary disruption of distributions on the securities.

      Cash Flow Agreements and External Credit Enhancements are Subject to Third
Party Risk.  The assets of a trust may, if specified  in the related  prospectus
supplement,  include cash flow  agreements,  such as swap, cap, floor or similar
agreements,  which will  require the  counterparty  to the trust (or the trustee
acting  on  behalf  of the  trust)  to make  payments  to the  trust  under  the
circumstances  described  in  the  prospectus  supplement.  If  payments  on the
securities of the related series depend in part on payments to be received under
one or these  agreements,  the  ability  of the  trust to make  payments  on the
securities will be subject to the credit risk of the counterparty.

      In addition, the ratings assigned to the securities of a series may depend
in part on the  ratings  assigned to the  provider of certain  types of external
credit  enhancement,  such as a mortgage  pool  insurance  policy,  surety bond,
financial guaranty  insurance policy or limited guarantee.  Any reduction in the
ratings  assigned  to the  provider  of one of these  types of  external  credit
enhancement  could  result  in the  reduction  of the  ratings  assigned  to the
securities of the series.  A reduction in the ratings assigned to the securities
of a series is likely to affect  adversely the liquidity and market value of the
securities.

      See  "Description  of Credit  Support" and "Cash Flow  Agreements" in this
prospectus.

      Amounts  Received  from an Auction  and a Related  Swap  Agreement  May Be
Insufficient to Assure Completion of the Auction. If specified in the prospectus
supplement  for a series,  one or more classes of securities may be subject to a
mandatory  auction.  If you hold a class of  securities  subject to a  mandatory
auction, on the distribution date specified in the related prospectus supplement
for the auction your security will be transferred to successful auction bidders,
thereby ending your investment in that security. If the security balance of your
class of  auction  securities  plus,  if  applicable,  accrued  interest,  after
application of all distributions and realized losses on the distribution date of
the auction,  is greater than the amount received in the auction, a counterparty
will be  obligated,  pursuant  to a swap  agreement,  to pay the  amount of that
difference to the  administrator  of the auction for distribution to the holders
of the class of auction securities. Auction bidders will be permitted to bid for
all or a portion of a class of auction securities. If the counterparty under the
swap agreement  defaults on its  obligations,  no

                                       13



bids for all or a portion  of a class of  auction  securities  will be  accepted
unless  the amount of the bids are equal to the  security  balance of a class of
auction securities plus, if applicable,  accrued interest,  after application of
all  distributions  and realized losses on the distribution  date of the auction
(or the pro rata  portion of this  price).  If the  counterparty  under the swap
agreement defaults and no bids for a class of auction securities or portion of a
class are  accepted  or there are no bids for the class or portion of the class,
all or a portion  of the  securities  of the class  will not be  transferred  to
auction bidders. In the event this happens,  you will retain the non-transferred
portion of your securities after the distribution date for the auction.

      See  "Description  of the  Securities--Mandatory  Auction  of the  Auction
Securities" in this prospectus.

      Servicing Transfer Following Event of Default May Result in Payment Delays
or Losses.  Following the  occurrence of an event of default under a pooling and
servicing agreement,  indenture or underlying  servicing agreement,  the trustee
for the related  series may, in its  discretion  or pursuant to  direction  from
securityholders,  remove the defaulting  master servicer or servicer and succeed
to its  responsibilities,  or may petition a court to appoint a successor master
servicer or servicer.  The trustee or the successor  master servicer or servicer
will be  entitled  to  reimbursement  of its costs of  effecting  the  servicing
transfer from the predecessor master servicer or servicer, or from the assets of
the  related  trust  if  the  predecessor  fails  to  pay.  In  the  event  that
reimbursement  to the trustee or the  successor  master  servicer or servicer is
made from trust assets, the resulting  shortfall will be borne by holders of the
related securities,  to the extent not covered by any applicable credit support.
In  addition,  during the  pendency  of a  servicing  transfer  or for some time
thereafter,  mortgagors  of the related  mortgage  loans may delay  making their
monthly  payments  or  may   inadvertently   continue  making  payments  to  the
predecessor  servicer,  potentially  resulting in delays in distributions on the
related securities.

Risks Associated with the Assets

      Sub-Prime  Mortgage Loans May Experience  Greater Rates of Delinquency and
Foreclosure.  All or a portion  of the  mortgage  loans  underlying  a series of
securities may consist of mortgage  loans  underwritten  in accordance  with the
underwriting  for  sub-prime  mortgage  loans.  A sub-prime  mortgage  loan is a
mortgage loan that is  ineligible  for purchase by Fannie Mae or the Freddie Mac
due  to  borrower  credit  characteristics,   high  loan-to-value  ratios,  high
debt-to-income ratios, property  characteristics,  loan documentation guidelines
or other  credit  characteristics  that do not meet  Fannie Mae or  Freddie  Mac
underwriting guidelines. As a consequence:

      o     delinquencies  and  foreclosures  may be  expected to be more likely
            with  respect  to  sub-prime  mortgage  loans  than with  respect to
            mortgage loans  originated in accordance  with Fannie Mae or Freddie
            Mac underwriting guidelines; and

      o     changes in the values of the mortgaged properties may have a greater
            effect on the loss  experience of sub-prime  mortgage  loans than on
            mortgage loans  originated in accordance  with Fannie Mae or Freddie
            Mac underwriting guidelines.

      In the event  these  mortgage  loans do become  delinquent  or  subject to
liquidation,  you may face delays in receiving  payment and may suffer losses if
the credit  enhancements for the series are insufficient to cover the delays and
losses.

      Mortgage  Loans Secured by Multifamily  Properties May Experience  Greater
Rates of Delinquency and Foreclosure.  The ability of a borrower to repay a loan
secured by an  income-producing  property typically is dependent  primarily upon
the  successful  operation of such  property  rather than upon the  existence of
independent   income  or  assets  of  the  borrower;   thus,  the  value  of  an
income-producing  property  typically is directly  related to the net  operating
income derived from such property.  If the net operating  income of the property
is reduced (for example, if rental or occupancy rates decline or real estate tax
rates or other operating expenses increase), the borrower's ability to repay the
loan may be impaired. In addition, the concentration of default, foreclosure and
loss risk for a pool of mortgage loans secured by multifamily  properties may be
greater than for a pool of mortgage loans secured by single family properties of
comparable aggregate unpaid principal balance because the pool of mortgage loans
secured by  multifamily  properties is likely to consist of a smaller  number of
higher balance loans.

      General  Economic  Conditions  Affect Mortgage Loan  Performance.  General
economic conditions have an impact on the ability of borrowers to repay mortgage
loans.  Loss of  earnings,  illness  and other  similar  factors  may lead to an
increase in delinquencies and bankruptcy  filings by borrowers.  In the event of
personal bankruptcy of a borrower under a mortgage loan, it is possible that the
holders of the related  securities  could experience a loss with respect to such
mortgagor's  mortgage  loan. In  conjunction  with a mortgagor's  bankruptcy,  a
bankruptcy court may suspend or reduce the payments of principal and interest to
be paid with respect to such mortgage loan, thus delaying the amount received by
the  holders of the  related  securities  with  respect to such  mortgage  loan.
Moreover,  if a bankruptcy court prevents the transfer of the related  mortgaged
property to the related trust,  any remaining  balance on such mortgage loan may
not be recoverable.

      Real  Estate  Market  Conditions  Affect  Mortgage  Loan  Performance.  An
investment  in the  securities  which are secured by or  represent  interests in
mortgage loans may be affected by, among other things,  a decline in real estate
values.  There is no assurance that the values of the mortgaged  properties will
remain  at the  levels  existing  on the  dates of  origination  of the  related
mortgage loans.

      If the residential real estate market should experience an overall decline
in property  values such that the  outstanding  balances of the  mortgage  loans
contained in a particular  trust and any  secondary  financing on the  mortgaged
properties,  become  equal  to or  greater  than  the  value  of  the  mortgaged
properties,  delinquencies,  foreclosures  and losses could be higher than those
now generally experienced in the mortgage lending industry.

      Geographic  Concentration May Increase Rates of Loss and Delinquency.  The
assets  underlying  certain series of securities may be  concentrated in certain
regions.  Any concentration may present risk considerations in addition to those
generally present for similar asset-backed securities without a concentration in
a  particular  region.  At  various  times,   certain  geographic  regions  will
experience  weaker economic  conditions and housing  markets and,  consequently,
will  experience  higher  rates  of  delinquency  and  loss  on  mortgage  loans
generally.  In addition,  certain  states have  experienced  natural  disasters,
including  earthquakes,  fires,  floods and  hurricanes,  which may not be fully
insured  against and may adversely  affect property  values.  See the applicable
table or tables in Appendix A to the related prospectus supplement detailing the
geographic   concentration   of  assets  for  listings  of  the   locations  and
concentrations of assets underlying the securities of a series.

      Any  deterioration  in housing  prices in a state or region due to adverse
economic conditions, natural disaster or other factors, and any deterioration of
economic  conditions in a state or region that adversely  affects the ability of
borrowers  to make  payments on the assets,  may result in losses on the assets.
Any losses may adversely affect the yield to maturity of the related securities.
Any  increase  in the market  value of  properties  located in a state or region
would reduce the combined  loan-to-value ratios of the related assets and could,
therefore,  make alternative  sources of financing available to the borrowers at
lower interest  rates,  which could result in an increased rate of prepayment of
these assets.

      See  "The  Mortgage  Pool"  and  Appendix  A  in  the  related  prospectus
supplement for further information regarding the geographic concentration of the
assets underlying the securities of any series.

      Risk of Loss May Be  Greater  on Junior  Mortgage  Loans.  Certain  of the
mortgage loans underlying the securities of a series may be secured by mortgages
junior or  subordinate  to one or more other  mortgages,  and the  related  more
senior mortgages may not be included in the trust fund.  Although little data is
available,  the rate of default of second or more junior  mortgage  loans may be
greater  than that of  mortgage  loans  secured  by senior  liens on  comparable
properties.  A primary  risk to  holders  of  mortgage  loans  secured by junior
mortgages  is the  possibility  that  adequate  funds  will not be  received  in
connection  with a foreclosure of the related  senior  mortgage to satisfy fully
both the senior mortgage and the mortgage that is junior or subordinate. In such
case, holders of the securities would bear:

      o     the risk of  delay  in  distributions  while a  deficiency  judgment
            against the borrower is obtained; and

      o     the risk of loss if the deficiency judgment is not realized upon.

                                       15



      Moreover,   deficiency   judgments   may  not  be   available  in  certain
jurisdictions. In addition, a junior mortgagee may not foreclose on the property
securing a junior  mortgage  unless it  forecloses  subject  to the more  senior
mortgage.

      In servicing junior  mortgages,  many servicers  advance funds to keep the
senior mortgage current if the mortgagor is in default  thereunder,  but only to
the extent that they  determine  such advances will be  recoverable  from future
payments and  collections on that mortgage loan or otherwise.  Such practice may
not be followed in servicing  loans more junior than second  mortgages or may be
modified at any time.  The related trust will have no source of funds to satisfy
any senior  mortgage or make  payments due to any senior  mortgagee.  The junior
mortgages  securing the mortgage loans are subject and subordinate to any senior
mortgage  affecting the related mortgaged  property,  including  limitations and
prohibitions  which may be contained in such senior  mortgage  upon  subordinate
financing.

      Special Risks of Certain  Assets.  Certain  assets that may be included in
the Trust may  involve  additional  uncertainties  not present in other types of
assets.  Certain of the assets may provide for  escalating or variable  payments
that may be larger than the initial payment amount; however, the borrowers under
such assets are generally  approved on the basis of the initial  payment  amount
and the  borrower's  income  may not be  sufficient  to  enable  them to pay the
increased  payment amounts.  Therefore,  in such cases the likelihood of default
may increase.

      Certain of the assets  underlying a series of securities may be delinquent
in respect of the payment of principal and interest. In addition, certain of the
mortgagors  under the mortgage  loans  underlying a series of securities  may be
subject to personal  bankruptcy  proceedings.  Credit enhancement  provided with
respect to a particular series of securities may not cover all losses related to
such mortgage  loans.  Prospective  investors  should consider the risk that the
inclusion in a trust of  delinquent  assets and  mortgage  loans with respect to
which the mortgagor is the subject of bankruptcy  proceedings may cause the rate
of the defaults and  prepayments  on such assets to increase  and, in turn,  may
cause  losses to exceed the  available  credit  enhancement  for such series and
affect the yield on the  securities of such series.  See "The Mortgage  Pool" in
the related prospectus supplement.

      Alternatives  to Foreclosure  May Adversely  Affect Yield.  Certain assets
underlying a series of securities may become  delinquent after the closing date.
A servicer may either  foreclose on any such asset or work out an agreement with
the  borrower if the  delinquency  is not cured,  which may  involve  waiving or
modifying  certain terms of the asset. If a servicer  extends the payment period
or accepts a lesser  amount than stated in the note or contract in  satisfaction
of the note or contract, the yield on the related securities may be reduced.

      Defaulted  Assets May  Experience  Delays in Liquidation  and  Liquidation
Proceeds May Be Less than the Outstanding  Principal  Balance of the Asset. Even
assuming the  applicable  collateral  provide  adequate  security for the assets
underlying a series of securities, substantial delays could result in connection
with the  liquidation of defaulted  assets.  This could result in  corresponding
delays in the receipt of the related  proceeds  by the related  trust.  Further,
liquidation  expenses such as legal fees,  real estate taxes and maintenance and
preservation expenses will reduce the portion of liquidation proceeds payable to
you. If the applicable  collateral  fails to provide  adequate  security for the
asset,  you will incur a loss on your investment if the credit  enhancements are
insufficient to cover the loss.

      Liquidation  Expenses May be  Disproportionate.  Liquidation expenses with
respect to defaulted assets do not vary directly with the outstanding  principal
balance  of the  assets at the time of  default.  Therefore,  assuming  that the
servicer and master  servicer took the same steps in realizing  upon a defaulted
asset having a small remaining  principal balance as they would in the case of a
defaulted asset having a large remaining principal balance,  the amount realized
after  expenses  of  liquidation  would  be  smaller  as  a  percentage  of  the
outstanding principal balance of the small asset than would be the case with the
defaulted asset having a large remaining principal balance.  Because the average
outstanding principal balance of the assets is small relative to the size of the
average outstanding  principal balance of the loans in a typical pool consisting
only of conventional  purchase-money mortgage loans, net liquidation proceeds on
liquidated  assets may also be smaller as a percentage of the principal  balance
of the  assets  than  would be the case in a  typical  pool  consisting  only of
conventional purchase-money mortgage loans.

                                       16



      Balloon  Payment  Assets  May Have a  Greater  Default  Risk at  Maturity.
Certain of the  underlying  a series of  securities  may  provide for a lump-sum
payment  of the  unamortized  principal  balance  of the  mortgage  loan  at the
maturity  of the  asset.  See  "The  Mortgage  Pool" in the  related  prospectus
supplement.

      Because  borrowers  under  this  type  of  asset  are  required  to make a
relatively  large single payment upon maturity,  it is possible that the default
risk   associated  with  such  assets  is  greater  than  that  associated  with
fully-amortizing  mortgage  loans.  The ability of a  mortgagor  on this type of
asset to repay the  mortgage  loan upon  maturity  frequently  depends  upon the
mortgagor's ability:

      o     to  refinance  the  asset,  which  will be  affected  by a number of
            factors,  including,  without  limitation,  the  level  of  mortgage
            interest rates available in the primary mortgage market at the time,
            the  mortgagor's  equity  in the  related  mortgaged  property,  the
            financial condition of the mortgagor, the condition of the mortgaged
            property,  tax law,  general  economic  conditions  and the  general
            willingness of financial  institutions  and primary mortgage bankers
            to extend credit; or

      o     to sell the  related  mortgaged  property at a price  sufficient  to
            permit the mortgagor to make the lump-sum payment.

      Collateral Securing  Cooperative Loans May Diminish in Value. If specified
in the  related  prospectus  supplement,  certain of the  mortgage  loans may be
cooperative loans. There are certain risks that differentiate  cooperative loans
from other types of mortgage loans. Ordinarily, the cooperative incurs a blanket
mortgage in connection with the  construction  or purchase of the  cooperative's
apartment building and the underlying land. The interests of the occupants under
proprietary  leases or occupancy  agreements to which the cooperative is a party
are generally subordinate to the interest of the holder of the blanket mortgage.
If the cooperative is unable to meet the payment  obligations  arising under its
blanket mortgage,  the mortgagee holding the blanket mortgage could foreclose on
that  mortgage and terminate all  subordinate  proprietary  leases and occupancy
agreements.  In  addition,  the 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 lump sum at final  maturity.
The inability of the  cooperative  to refinance this mortgage and its consequent
inability to make such final payment could lead to  foreclosure by the mortgagee
providing  the  financing.  A  foreclosure  in either event by the holder of the
blanket  mortgage  could  eliminate or  significantly  diminish the value of the
collateral securing the cooperative loans.

      Leaseholds  May Be Subject to Default  Risk on the  Underlying  Lease.  If
specified in the related  prospectus  supplement,  certain of the mortgage loans
may be  secured by  leasehold  mortgages.  Leasehold  mortgages  are  subject to
certain risks not associated  with mortgage loans secured by a fee estate of the
mortgagor. The most significant of these risks is that the ground lease creating
the leasehold estate could terminate,  leaving the leasehold  mortgagee  without
its security. The ground lease may terminate, if among other reasons, the ground
lessee breaches or defaults in its  obligations  under the ground lease or there
is a  bankruptcy  of the  ground  lessee or the  ground  lessor.  Any  leasehold
mortgages  underlying a series of securities will contain provisions  protective
of  the  mortgagee,  to  the  extent  described  in  the  applicable  prospectus
supplement.

      Increased Risk of Loss if Assets are  Delinquent.  A portion of the assets
may  be  delinquent  upon  the  issuance  of  the  related  securities.   Credit
enhancement  provided with respect to a particular  series of securities may not
cover  all  losses  related  thereto.  You  should  consider  the risk  that the
inclusion  of such  assets in the trust  fund for a series may cause the rate of
defaults  and  prepayments  on the assets to increase  and,  in turn,  may cause
losses to exceed the available credit enhancement for such series and affect the
yield on the securities of such series.

      Violations of Federal,  State and Local Laws May Adversely  Affect Ability
to Collect on Loans.  The mortgage  loans may also be subject to federal,  state
and local laws, including:

      o     the Federal Truth in Lending Act and Regulation Z promulgated  under
            that  act,  which  require  certain  disclosures  to  the  borrowers
            regarding the terms of the residential loans;

      o     the Equal Credit  Opportunity Act and Regulation B promulgated under
            that act, which prohibit  discrimination  on the basis of age, race,
            color, sex, religion,  marital status,  national origin,  receipt of

                                       17



            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 borrower's credit experience; and

      o     for mortgage loans that were  originated or closed after November 7,
            1989, the Home Equity Loan Consumer  Protection  Act of 1988,  which
            requires additional disclosures,  limits changes that may be made to
            the loan  documents  without the borrower's  consent.  This act also
            restricts  a lender's  ability to declare a default or to suspend or
            reduce a borrower's credit limit to certain enumerated events.

      Certain mortgage loans are subject to the Riegle Community Development and
Regulatory  Improvement  Act of 1994 which  incorporates  the Home Ownership and
Equity Protection Act of 1994. These provisions may:

      o     impose  additional  disclosure and other  requirements  on creditors
            with respect to non-purchase money mortgage loans with high interest
            rates or high up-front fees and charges;

      o     apply on a mandatory  basis to all mortgage  loans  originated on or
            after October 1, 1995;

      o     impose  specific  statutory  liabilities  on  creditors  who fail to
            comply with their provisions; and

      o     affect the enforceability of the related loans.

      In addition,  any assignee of the creditor  would  generally be subject to
all claims and defenses  that the consumer  could assert  against the  creditor,
including,   without  limitation,  the  right  to  rescind  the  mortgage  loan.
Violations  of certain  provisions  of these  laws may limit the  ability of the
servicer to collect all or part of the  principal of or interest on the mortgage
loans, may entitle the mortgagor to a refund of amounts  previously paid and may
subject the depositor, the servicer, the master servicer or the trust to damages
and  administrative  enforcement.  As a  result,  these  violations  or  alleged
violations  could  result  in  shortfalls  in  the  distributions  due  on  your
securities.

      In the past few  years,  a  number  of  legislative  proposals  have  been
introduced  at both the  federal,  state and local  level that are  designed  to
discourage predatory lending practices.  Some states have enacted, or may enact,
laws or regulations that prohibit inclusion of some provisions in mortgage loans
that have mortgage  interest rates or origination  costs in excess of prescribed
levels,  and require that  borrowers be given certain  disclosures  prior to the
consummation  of such mortgage  loans.  In some cases,  state and local laws may
impose  requirements and  restrictions  greater than those in the Home Ownership
and Equity Protection Act of 1994.  Lawsuits have been brought in various states
making claims against  assignees of high cost loans for violations of state law.
Named  defendants  in these  cases  include  numerous  participants  within  the
secondary mortgage market,  including some securitization  trusts. The seller of
the  assets,  either  directly  or  indirectly,   to  the  depositor  will  make
representations and warranties with respect to each asset relating to compliance
with federal, state and local laws at the time of origination,  that none of the
mortgage  loans are subject to the Home  Ownership and Equity  Protection Act of
1994 and that none of the  mortgage  loans  are "high  cost"  loans  within  the
meaning of such  federal,  state and local laws. In the event of a breach of any
such  representations,  the party specified in the related prospectus supplement
will be  required  to cure such breach or  repurchase  or replace  the  affected
mortgage loan. In addition, such party will be required to reimburse the related
trust fund for any damages or costs incurred by such trust fund as a result of a
breach of the  representation  as to compliance  with  federal,  state and local
laws. To the extent Bank of America,  National  Association  is the sponsor of a
series, it will be also make the  representations  and warranties above and cure
or  repurchase  the affected  mortgage loan and reimburse the trust fund for any
costs and damages to the extent the seller of the assets  fails to do so. To the
extent no party  fulfills this  reimbursement  obligation for financial or other
reasons, shortfalls in the distributions due on your securities could occur. See
"Description  of the  Agreements--Material  Terms of the Pooling  and  Servicing
Agreements and Underlying Servicing  Agreements--Representations and Warranties;
Repurchases" in this prospectus.

                                       18



      The home  improvement  contracts are also subject to the  Preservation  of
Consumers'  Claims and Defenses  regulations of the Federal Trade Commission and
other similar federal and state statutes and regulations. These laws:

      o     protect the homeowner  from  defective  craftsmanship  or incomplete
            work by a contractor;

      o     permit the obligated party to withhold  payment if the work does not
            meet the quality and durability standards agreed to by the homeowner
            and the contractor; and

      o     subject  any  person to whom the  seller of the  goods  assigns  its
            consumer  credit  transaction  to all claims and defenses  which the
            obligated  party in a credit sale  transaction  could assert against
            such seller.

      Market  Values  of  Manufactured  Homes  May  Increase  the  Risk of Loss.
Manufactured  homes generally  depreciate in value. Thus investors should expect
that, as a general  matter,  the market value of any  manufactured  home will be
lower  than  the  outstanding  principal  balance  of  the  related  installment
contract.  As a  result,  investors  must be  prepared  to bear the risk of loss
resulting from any  delinquency or liquidation  loss on the contracts in a trust
fund, to the extent not covered by the applicable credit support.

      Risk of Loss May Be Greater  on  Unsecured  Home  Improvement  Loans.  The
obligations of the borrower under any unsecured home  improvement  loan included
in a trust fund will not be secured by an interest in the related real estate or
any other property. In the event of a default, the trust fund will have recourse
only  against the  borrower's  assets  generally,  along with all other  general
unsecured creditors of the borrower.  In a bankruptcy or insolvency  proceeding,
the obligations of the borrower under an unsecured home  improvement loan may be
discharged in their entirety.  As a result, the trust fund may suffer losses. In
addition,  a borrower on an unsecured home  improvement loan may not demonstrate
the same degree of concern over performance of the borrower's  obligations as if
such  obligations  were secured by the real estate or other assets owned by such
borrower.

      Risks of Loss May Increase Due to Defective  Security Interest and Effects
of Certain  Other  Legal  Aspects of the  Contracts.  The seller of the  assets,
either  directly or indirectly,  to the depositor will represent that a contract
is secured by a security  interest in a  manufactured  home.  Perfection of such
security  interests and the right to realize upon the value of the  manufactured
homes as  collateral  for the  contracts  are subject to a number of federal and
state laws,  including  the Uniform  Commercial  Code.  The steps  necessary  to
perfect the  security  interest in a  manufactured  home will vary from state to
state.  Because of the expense and administrative  inconvenience  involved,  the
servicer  or the master  servicer  will not amend any  certificates  of title to
change the  lienholder  specified  therein  from the seller of the assets to the
trustee  and will not deliver  any  certificate  of title to the trustee or note
thereon the trustee's interest.  Consequently, in some states, in the absence of
such an amendment, the assignment to the trustee of the security interest in the
manufactured  home may not be  effective  or such  security  interest may not be
perfected  and,  may not be  effective  against  creditors  of the seller of the
assets or a trustee in bankruptcy of such seller.

      In addition,  numerous  federal and state consumer  protection laws impose
requirements on lending under  installment  sales contracts and installment loan
agreements  such as the  contracts,  and the  failure by the lender or seller of
goods to comply  with  such  requirements  could  give  rise to  liabilities  of
assignees for amounts due under such agreements and claims by such assignees may
be subject to set-off as a result of such  lender's or  seller's  noncompliance.
These laws would apply to the trustee as assignee of the  contracts.  The seller
of the assets of the contracts will warrant that each contract complies with all
requirements of law and will make certain  warranties  relating to the validity,
subsistence,   perfection  and  priority  of  the  security   interest  in  each
manufactured  home  securing  a  contract.  A breach of any such  warranty  that
materially  adversely  affects any contract  would create an  obligation  of the
seller of the assets to repurchase, or if permitted by the applicable agreement,
substitute for, such contract unless such breach is cured. If the credit support
is  exhausted  and  recovery of amounts due on the  contracts  is  dependent  on
repossession  and resale of  manufactured  homes securing  contracts that are in
default,  certain  other  factors  may limit the  ability  to  realize  upon the
manufactured  home or may limit the amount realized by  securityholders  to less
than the amount due.

                                       19



                         DESCRIPTION OF THE TRUST FUNDS

Assets

      The primary  assets of each Trust Fund (the  "Assets" ) will include (i) a
segregated  pool of single family and/or  multifamily  mortgage  loans which may
include  sub-prime  mortgage  loans (the "Mortgage  Loans" ), including  without
limitation,  Home  Equity  Loans,  Home  Improvement  Contracts  and  Land  Sale
Contracts,  (ii) home  improvement  installment  sales  contracts or installment
loans  that are  unsecured  (the  "Unsecured  Home  Improvement  Loans" ), (iii)
manufactured housing installment sales contracts and installment loan agreements
(the  "Contracts"  ) or (iv) a combination  of Mortgage  Loans,  Unsecured  Home
Improvement Loans and/or Contracts. The Mortgage Loans will not be guaranteed or
insured by the Depositor 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 related  prospectus
supplement. If specified in the related prospectus supplement,  the sponsor of a
Series may have  purchased  the Assets from a prior holder (an "Asset  Seller"),
which  prior  holder may or may not be the  originator  of such  Mortgage  Loan,
Unsecured Home Improvement Loan or Contract.

      The  Assets  included  in the Trust  Fund for a Series  may be  subject to
various  types of payment  provisions.  Such  Assets  may  consist of (1) "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;  (2) "Adjustable Rate Assets,"
which may provide for periodic  adjustments  to their rates of interest to equal
the sum (which may be  rounded)  of a fixed  margin and an index;  (3) "Buy Down
Assets,"  which are Assets for which funds have been  provided by someone  other
than the related  obligors to reduce the obligors'  monthly  payments during the
early period after origination of such Assets; (4) "Increasing  Payment Assets,"
as described  below;  (5)  "Interest  Reduction  Assets,"  which provide for the
one-time reduction of the interest rate payable thereon; (6) "GEM Assets," which
provide for (a) monthly  payments during the first year after  origination  that
are at least sufficient to pay interest due thereon, and (b) an increase in such
monthly payments in subsequent  years at a predetermined  rate resulting in full
repayment  over a  shorter  term  than the  initial  amortization  terms of such
Assets;  (7) "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 the unpaid
principal  balances  thereof,  and which  unpaid  interest  will be added to the
principal  balances  of such  Assets and will be paid,  together  with  interest
thereon,  in later years;  (8) "Step-up  Rate Assets" which provide for interest
rates that increase over time; (9) "Balloon  Payment  Assets" which are mortgage
loans that are not fully  amortizing  over their terms and, thus, will require a
lump-sum payment at their stated maturity;  (10) "Convertible  Assets" which are
Adjustable  Rate Assets  subject to  provisions  pursuant  to which,  subject to
certain limitations,  the related obligors may exercise an option to convert the
adjustable  interest rate to a fixed interest rate; and (11) "Bi-weekly Assets,"
which provide for obligor payments to be made on a bi-weekly basis.

      The applicable  prospectus supplement will set forth the relevant index or
indices with respect to the  Adjustable  Rate Assets in the related  Trust Fund.
The  indices  will  be one or  more of the  following:  one-month,  three-month,
six-month  or one-year  LIBOR (an  average of the  interest  rate on  one-month,
three-month,  six-month or one-year  dollar-denominated  deposits traded between
banks in London),  CMT (weekly or monthly average yields of U.S.  treasury short
and long-term  securities,  adjusted to a constant maturity),  COFI (an index of
the  weighted  average  interest  rate paid by savings  institutions  in Nevada,
Arizona and  California),  MTA (a one-year average of the monthly average yields
of U.S.  treasury  securities)  or the Prime Rate (an  interest  rate charged by
banks for short-term loans to their most creditworthy customers).

      An Increasing Payment Asset is an Asset that provides for monthly payments
that are fixed for an initial  period to be specified in the related  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  related  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 with respect to 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  obligor's  monthly  payments  referred  to in the
preceding  sentence and (2) in the case of certain  Increasing  Payment  Assets,
payments  made by the  respective  Servicers  pursuant  to  buy-down  or subsidy
agreements.  The obligor's initial monthly payments for each Increasing  Payment
Asset are set at the level-payment

                                       20



amount that would apply to an otherwise  identical Level Payment Asset having an
interest rate a certain number of percentage points below the Asset Rate of such
Increasing  Payment Asset.  The obligor's  monthly  payments on each  Increasing
Payment Asset,  together with any payments made thereon by the related Servicers
pursuant to buy-down or subsidy  agreements,  will in all cases be sufficient to
allow  payment of  accrued  interest  on such  Increasing  Payment  Asset at the
related  interest rate,  without  negative  amortization.  An obligor's  monthly
payments  on such an Asset  may,  however,  not be  sufficient  to result in any
reduction  of the  principal  balance of such Asset  until after the period when
such payments may be increased.

      The  Securities  will be entitled  to payment  only from the assets of the
related Trust Fund and will not be entitled to payments in respect of the assets
of any other  trust fund  established  by the  Depositor.  If  specified  in the
related  prospectus  supplement,  the  assets of a Trust  Fund will  consist  of
securities  representing  beneficial ownership interests in, or indebtedness of,
another trust fund that contains the Assets.

Mortgage Loans

      General

      Each  Mortgage  Loan will  generally  be secured by a lien on (i) a one-to
four-family  residential  property or a security  interest in shares issued by a
cooperative  housing  corporation  (a "Single  Family  Property" and the related
Mortgage Loan a "Single Family Mortgage  Loan") or (ii) a primarily  residential
property which consists of five or more  residential  dwelling units,  and which
may include limited  retail,  office or other  commercial  space (a "Multifamily
Property" and the related Mortgage Loan a "Multifamily  Mortgage Loan").  Single
Family  Properties and Multifamily  Properties are sometimes  referred to herein
collectively as "Mortgaged  Properties." To the extent  specified in the related
prospectus supplement, 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 include
stock,  shares  or  membership   certificates  issued  by  private,   nonprofit,
cooperative  housing  corporations,  known as "Cooperatives," and in the related
proprietary leases or occupancy  agreements  granting exclusive rights to occupy
specific  dwelling  units  in  such  Cooperatives'   buildings.   The  Mortgaged
Properties may include leasehold interests in properties,  the title to which is
held by third party  lessors.  The term of any such  leasehold  shall exceed the
term of the  related  mortgage  note by at least  five  years or such other time
period specified in the related  prospectus  supplement.  The Mortgage Loans may
include (i) closed-end  and/or  revolving home equity loans or certain  balances
thereof ("Home Equity Loans") and/or (ii) secured home  improvement  installment
sales  contracts and secured  installment  loan  agreements  ("Home  Improvement
Contracts").  In addition, the Mortgage Loans may include certain Mortgage Loans
evidenced  by  contracts  ("Land  Sale  Contracts")  for the sale of  properties
pursuant  to which the  mortgagor  promises to pay the amount due thereon to the
holder thereof with fee title to the related  property held by such holder until
the mortgagor has made all of the payments  required  pursuant to such Land Sale
Contract,  at which time fee title is conveyed to the mortgagor.  The Originator
of each  Mortgage  Loan will have been a person  other than the  Depositor.  The
related  prospectus  supplement  will indicate if any person who  originated the
Mortgage Loans (each an "Originator")  is an affiliate of the Depositor.  If any
Originator  or group of  affiliated  Originators  originated  10% or more of the
Mortgage  Loans in a Trust  Fund,  the  applicable  prospectus  supplement  will
disclose  the identity of the  Originator  and, if such  Originator  or group of
affiliated  Originators  originated  20% or  more  of the  Mortgage  Loans,  the
applicable prospectus supplement will provide information about the Originator's
form  of  organization  and,  to  the  extent  material,  a  description  of the
Originator's origination program and how long it has been engaged in originating
mortgage  loans of the same  type.  The  Mortgage  Loans  will be  evidenced  by
promissory notes (the "Mortgage Notes") secured by mortgages,  deeds of trust or
other security  instruments (the  "Mortgages")  creating a lien on the Mortgaged
Properties.

      Combined Loan-to-Value Ratio

      The "Combined Loan-to-Value Ratio" of a Mortgage Loan at any given time is
the ratio  (expressed  as a  percentage)  of (i) the sum of (a) the  outstanding
principal  balance of the Mortgage Loan at origination plus (b) in the case of a
second lien Mortgage Loan, the outstanding  principal  balance of the first lien
on the related  Mortgaged  Property at the date of  origination  of the Mortgage
Loan over (ii) the Value of the  related  Mortgaged  Property.  The "Value" of a
Mortgaged  Property is generally  the lesser of: (i) an amount  determined by an
appraisal  done at  origination  of the Mortgage Loan and (ii) other than in the
case of a refinanced  Mortgage  Loan,  the  purchase  price

                                       21



paid for the related  Mortgaged  Property by the Mortgagor  with the proceeds of
the Mortgage Loan.  The value of a Mortgaged  Property as of the date of initial
issuance  of the  related  Series  of  Securities  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.

      Mortgage Loan Information in Prospectus Supplements

      Each  prospectus  supplement  will  contain  information,  as of the dates
specified in such  prospectus  supplement and to the extent then  applicable and
specifically  known  to the  Depositor,  with  respect  to the  Mortgage  Loans,
including  (i) the  aggregate  outstanding  principal  balance and the  largest,
smallest and average  outstanding  principal balance of the Mortgage Loans as of
the  applicable  cut-off date (the "Cut-off  Date")  specified in the prospectus
supplement,  (ii) the type of property  securing the Mortgage  Loans,  (iii) the
occupancy  status,  (iv)  the  purpose,  (v) the  documentation  type,  (vi) the
weighted  average (by principal  balance) of the original and remaining terms to
maturity of the Mortgage Loans,  (vii) the earliest and latest  origination date
and maturity date of the Mortgage Loans,  (viii) the range of the  Loan-to-Value
Ratios at  origination  of the  Mortgage  Loans,  (ix) the credit  scores of the
Mortgagors,  (x) the Mortgage Interest Rates or range of Mortgage Interest Rates
and the weighted  average  Mortgage  Interest Rate borne by the Mortgage  Loans,
(xi) the geographic distribution of the Mortgaged Properties,  (xii) information
with respect to the prepayment provisions, if any, of the Mortgage Loans, (xiii)
with respect to Mortgage  Loans with  adjustable  Mortgage  Interest Rates ("ARM
Loans"),  the index, the frequency of the adjustment dates, the range of margins
added to the index,  and the maximum  Mortgage  Interest Rate or monthly payment
variation  at the time of any  adjustment  thereof  and over the life of the ARM
Loan, (xiv) information  regarding the payment  characteristics  of the Mortgage
Loans,  including  without  limitation  balloon  payment and other  amortization
provisions, (xv) the number of Mortgage Loans that are delinquent and the number
of days or ranges of the number of days such Mortgage  Loans are  delinquent and
(xvi) the  material  underwriting  standards  used for the  Mortgage  Loans.  If
specific information respecting the Mortgage Loans is not known to the Depositor
at the time Securities 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  which will be available to
purchasers of the related  Securities at or before the initial  issuance thereof
and will be filed as part of a Current  Report  on Form 8-K with the  Commission
after such initial issuance.  Notwithstanding the foregoing, the characteristics
of the Mortgage  Loans  included in a Trust Fund will not vary by more than five
percent  (by  aggregate  principal  balance  as of the  Cut-off  Date)  from the
characteristics thereof that are described in the related prospectus supplement.

      The related prospectus  supplement will specify whether the Mortgage Loans
include (i) Home Equity Loans, which may be secured by Mortgages that are junior
to other liens on the related  Mortgaged  Property and/or (ii) 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,
kitchen and bathroom remodeling goods, solar heating panels, patios, decks, room
additions and garages.  The related  prospectus  supplement will specify whether
the Home  Improvement  Contracts  are  partially  insured  under  Title I of the
National  Housing  Act of 1934 (the  "National  Housing  Act")  and,  if so, the
limitations on such insurance.  In addition,  the related prospectus  supplement
will specify whether the Mortgage Loans contain certain 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 such
other  interval as is  specified  in the related  prospectus  supplement  or for
payments in another manner described in the related prospectus supplement.  Each
Mortgage  Loan may provide for no accrual of interest or for accrual of interest
thereon at an interest rate (a "Mortgage  Interest 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 Interest Rate or a different  adjustable Mortgage
Interest Rate, or from a fixed to an adjustable  Mortgage  Interest  Rate,  from
time to time  pursuant to an election or as  otherwise  specified on the related
Mortgage Note, in each case as described in the related  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  Interest
Rate or to reflect the  occurrence of certain events or that adjust on the basis
of other methodologies, and may provide for

                                       22



negative amortization or accelerated amortization,  in each case as described in
the related 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 related 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 Charge") in connection with a prepayment,  in
each case as described in the related prospectus  supplement.  In the event that
holders of any Class or Classes of Offered Securities will be entitled to all or
a portion of any Prepayment  Charges collected in respect of Mortgage Loans, the
related  prospectus  supplement  will specify the method or methods by which any
such amounts will be allocated. See "--Assets" above.

      Revolving Credit Line Loans

      As more fully described in the related prospectus supplement, the Mortgage
Loans may  consist,  in whole or in part,  of  revolving  Home  Equity  Loans or
certain  balances  thereof  ("Revolving  Credit Line  Loans").  Interest on each
Revolving Credit Line Loan,  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 such loan.  From time to time
prior to the  expiration  of the related  draw period  specified  in a Revolving
Credit Line Loan,  principal  amounts on such Revolving  Credit Line Loan may be
drawn  down (up to a  maximum  amount  as set  forth in the  related  prospectus
supplement) or repaid. If specified in the related  prospectus  supplement,  new
draws by  borrowers  under the  Revolving  Credit Line Loans will  automatically
become part of the Trust Fund  described  in such  prospectus  supplement.  As a
result,  the aggregate balance of the Revolving Credit Line Loans will fluctuate
from day to day as new  draws by  borrowers  are  added  to the  Trust  Fund and
principal  payments  are applied to such  balances and such amounts will usually
differ  each day,  as more  specifically  described  in the  related  prospectus
supplement.  Under certain circumstances,  under a Revolving Credit Line Loan, 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 which 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 and FHA insured  unsecured home  improvement  loans. The
Unsecured  Home  Improvement  Loans will bear  interest  at a fixed or  variable
annual percentage rate.

      Unsecured Home Improvement Loan Information in Prospectus Supplements

      Each  prospectus  supplement  will  contain  information,  as of the dates
specified in such  prospectus  supplement and to the extent then  applicable and
specifically  known  to  the  Depositor,  with  respect  to the  Unsecured  Home
Improvement Loans, including (i) the aggregate 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,  (ii) the weighted
average (by principal  balance) of the original and remaining  terms to maturity
of  the  Unsecured  Home  Improvement  Loans,  (iii)  the  earliest  and  latest
origination  date and maturity date of the Unsecured  Home  Improvements  Loans,
(iv) the  interest  rates or range of interest  rates and the  weighted  average
interest rates borne by the Unsecured Home Improvement Loans, (v) the geographic
distributions  of the Unsecured Home  Improvement  Loans,  (vi) information with
respect to the prepayment provisions,  if any, of the Unsecured Home Improvement
Loans,  (vii)  with  respect  to  the  Unsecured  Home  Improvement  Loans  with
adjustable interest rates ("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,
(viii) information  regarding the payment  characteristics of the Unsecured Home
Improvement  Loan, (ix) the number of Unsecured Home Improvement  Loans that are
delinquent and the number of days or ranges of the number of days such Unsecured
Home Improvement Loans are delinquent,  (x) the material underwriting  standards
used for the Unsecured Home Improvement  Loans and (xi) the credit scores of the
borrowers of the  Unsecured  Home  Improvement  Loans.  If specific  information
respecting the Unsecured Home Improvement Loans is not known to the Depositor at
the time

                                       23



Securities  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 which will be available to purchasers
of the related  Securities at or before the initial issuance thereof and will be
filed as part of a Current  Report on Form 8-K with the  Commission  after  such
initial issuance.  Notwithstanding  the foregoing,  the  characteristics  of the
Unsecured Home Improvement  Loans included in a Trust Fund will not vary by more
than five percent (by aggregate  principal  balance as of the Cut-off Date) from
the  characteristics  thereof  that  are  described  in the  related  prospectus
supplement.

Contracts

      General

      To the extent provided in the related prospectus supplement, each Contract
will be secured by a security interest in a new or used manufactured home (each,
a "Manufactured  Home").  Such prospectus  supplement will specify the states or
other  jurisdictions  in which  the  Manufactured  Homes are  located  as of the
related  Cut-off  Date.  The method of computing  the  Loan-to-Value  Ratio of a
Contract will be described in the related prospectus supplement.

      Contract Information in Prospectus Supplements

      Each prospectus  supplement will contain  certain  information,  as of the
dates specified in such prospectus  supplement and to the extent then applicable
and  specifically  known  to the  Depositor,  with  respect  to  the  Contracts,
including  (i) the  aggregate  outstanding  principal  balance and the  largest,
smallest and average  outstanding  principal  balance of the Contracts as of the
applicable Cut-off Date, (ii) whether the Manufactured Homes were new or used as
of the  origination  of the related  Contracts,  (iii) the weighted  average (by
principal  balance)  of the  original  and  remaining  terms to  maturity of the
Contracts,  (iv) the earliest and latest  origination  date and maturity date of
the Contracts,  (v) the range of the Loan-to-Value  Ratios at origination of the
Contracts,  (vi) the Contract  Rates or range of Contract Rates and the weighted
average Contract Rate borne by the Contracts, (vii) the state or states in which
most of the Manufactured  Homes are located at origination,  (viii)  information
with respect to the prepayment provisions,  if any, of the Contracts,  (ix) with
respect to Contracts  with  adjustable  Contract  Rates ("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,  (x) the number of Contracts  that are  delinquent and
the  number  of  days  or  ranges  of the  number  of days  such  Contracts  are
delinquent,  (xi)  information  regarding  the  payment  characteristics  of the
Contracts, (xii) the material underwriting standards used for the Contracts, and
(xiii) the credit  scores of the  borrowers  under the  Contracts.  If  specific
information  respecting  the Contracts is not known to the Depositor at the time
Securities  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 which will be available to purchasers
of the related  Securities at or before the initial issuance thereof and will be
filed as part of a Current  Report on Form 8-K with the  Commission  after  such
initial issuance.  Notwithstanding  the foregoing,  the  characteristics  of the
Contracts  included in a Trust Fund will not vary by more than five  percent (by
aggregate  principal  balance as of the Cut-off  Date) from the  characteristics
thereof that are described in the related prospectus supplement.

      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 such other  interval as is specified
in the related 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 an annual  percentage  rate (a
"Contract  Rate") that is fixed over its term or that adjusts from time to time.
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 related prospectus supplement. See "--Assets" above.

                                       24



Pre-Funding Account

      To the  extent  provided  in a  prospectus  supplement,  a portion  of the
proceeds  of the  issuance  of  Securities  may be  deposited  into  an  account
maintained  with the  Trustee (a  "Pre-Funding  Account").  In such  event,  the
Depositor will be obligated  (subject only to the availability  thereof) to sell
at a  predetermined  price,  and the  Trust  Fund  for  the  related  Series  of
Securities will be obligated to purchase (subject to the availability  thereof),
additional Assets (the "Subsequent  Assets") from time to time (as frequently as
daily)  within the period (not to exceed  three  months if a REMIC  election has
been made or one year in all other cases)  specified  in the related  prospectus
supplement  (the  "Pre-Funding  Period")  after the  issuance  of such Series of
Securities  having an aggregate  principal  balance  approximately  equal to the
amount on deposit in the Pre-Funding Account (the "Pre-Funded  Amount") for such
Series on the date of such  issuance.  The  Pre-Funded  Amount with respect to a
Series  will not exceed 50% of the  aggregate  initial  Security  Balance of the
related  Securities.  Any Subsequent  Assets will be required to satisfy certain
eligibility  criteria more fully set forth in the  applicable  Agreement,  which
eligibility  criteria will be consistent  with the  eligibility  criteria of the
Assets initially  included in the Trust Fund,  subject to such exceptions as are
expressly  stated in the  prospectus  supplement.  For example,  the  Subsequent
Assets will be subject to the same underwriting  standards,  representations and
warranties  as the Assets  initially  included in the Trust Fund.  In  addition,
certain   conditions  must  be  satisfied  before  the  Subsequent   Assets  are
transferred  into the Trust Fund such as the delivery to the Rating Agencies and
the Trustee of certain opinions of counsel.

      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  Securities  in the  amounts  and  in the  manner  specified  in the  related
prospectus  supplement.  In addition,  if  specified  in the related  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  with  respect to the
Securities  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 related prospectus supplement.

Accounts

      Each  Trust  Fund  will  include  one or more  accounts,  established  and
maintained  on behalf of the  Securityholders  into  which the person or persons
designated in the related  prospectus  supplement  will, to the extent described
herein and in such  prospectus  supplement  deposit all payments and collections
received or advanced  with  respect to the Assets and other  assets in the Trust
Fund. Such an account may be maintained as an interest bearing or a non-interest
bearing  account,  and funds held  therein  may be held as cash or  invested  in
certain short-term,  investment grade obligations,  in each case as described in
the related prospectus supplement.  See "Description of the Agreements--Material
Terms  of  the  Pooling  and  Servicing   Agreements  and  Underlying  Servicing
Agreements--Collection Account and Related Accounts."

                                 USE OF PROCEEDS

      The  Depositor  will apply the net proceeds  received from the sale of the
Securities to the purchase of Assets, or the repayment of the financing incurred
in such  purchase.  The Depositor  expects to sell the  Securities  from time to
time,  but the timing and amount of  offerings  of  Securities  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
holder of the Security  (the  "Securityholder"),  the  Pass-Through  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 Trust Fund (which may be
affected by  prepayments,  defaults,  liquidations  or  repurchases).  See "Risk
Factors--Risks  Associated with the Securities--Rate of Prepayment on Assets May
Adversely Affect Average Lives and Yields on the Securities."

                                       25


Pass-Through Rate and Interest Rate

      Securities  of any  Class  within a Series  may have  fixed,  variable  or
adjustable  Pass-Through  Rates or interest rates, which may or may not be based
upon the  interest  rates  borne by the Assets in the related  Trust  Fund.  The
prospectus  supplement with respect to any Series of Securities will specify the
Pass-Through  Rate or interest rate for each Class of such Securities or, in the
case of a variable or adjustable  Pass-Through Rate or interest rate, the method
of determining the  Pass-Through  Rate or interest rate; the effect,  if any, of
the prepayment of any Asset on the Pass-Through  Rate or interest rate of one or
more Classes of  Securities;  and whether the  distributions  of interest on the
Securities  of any  Class  will  be  dependent,  in  whole  or in  part,  on the
performance of any obligor under a Cash Flow Agreement.

      If so specified in the related prospectus supplement,  the effective yield
to maturity to each holder of  Securities  entitled to payments of interest will
be below that otherwise produced by the applicable Pass-Through Rate or interest
rate and purchase price of such Security  because,  while interest may accrue on
each Asset during a certain period (each,  an "Interest  Accrual  Period"),  the
distribution  of such  interest will be made on a day which may be several days,
weeks or months following the period of accrual.

Timing of Payment of Interest

      Each  payment of interest on the  Securities  (or addition to the Security
Balance of a Class of Accrual  Securities)  on the  monthly,  quarterly or other
periodic  date  specified  in  the  related   prospectus   supplement  on  which
distributions will be made to holders of Securities (a "Distribution Date") will
include   interest   accrued  during  the  Interest   Accrual  Period  for  such
Distribution  Date. As indicated above under  "--Pass-Through  Rate and Interest
Rate," if the Interest 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
such  Securities  may be lower than the yield that would  result if the Interest
Accrual Period ended on such day before the Distribution Date.

Payments of Principal; Prepayments

      The yield to  maturity on the  Securities  will be affected by the rate of
principal  payments on the Assets (including  principal  prepayments on Mortgage
Loans and Contracts  resulting from both voluntary  prepayments by the borrowers
and involuntary liquidations).  The rate at which principal prepayments occur on
the  Mortgage  Loans and  Contracts  will be  affected  by a variety of factors,
including,  without  limitation,  the terms of the Mortgage Loans and Contracts,
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 Mortgage
Interest  Rates on the Mortgage  Loans  comprising or underlying the Assets in a
particular  Trust  Fund,  such  Mortgage  Loans are likely to be the  subject of
higher  principal  prepayments  than if prevailing  rates remain at or above the
rates borne by such  Mortgage  Loans.  In this  regard,  it should be noted that
certain Assets may consist of Mortgage Loans with  different  Mortgage  Interest
Rates.  The  rate  of  principal  payments  on  some  or all of the  Classes  of
Securities of a Series will correspond to the rate of principal  payments on the
Assets in the related  Trust Fund and is likely to be affected by the  existence
of Lock-out  Periods and  Prepayment  Charge  provisions  of the Mortgage  Loans
underlying or comprising such Assets, and by the extent to which the Servicer of
any such Mortgage Loan is able to enforce such provisions. Mortgage Loans with a
Lock-out Period or a Prepayment  Charge  provision,  to the extent  enforceable,
generally would be expected to experience a lower rate of principal  prepayments
than otherwise  identical  Mortgage Loans without such provisions,  with shorter
Lock-out Periods or with lower Prepayment  Charges.  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  smaller  effect  on the  amount  of  the  monthly  payments  on
manufactured  housing  contracts  than 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.  Conversely,  local economic  conditions and certain 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,  the
actual yield

                                       26



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,  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  Securities,  the  effect  on yield on one or more
Classes of the  Securities  of such Series of  prepayments  of the Assets in the
related  Trust  Fund may be  mitigated  or  exacerbated  by any  provisions  for
sequential or selective distribution of principal to such Classes.

      When a full  prepayment  is made on a  Mortgage  Loan or a  Contract,  the
obligor  generally is charged  interest on the principal  amount of the Mortgage
Loan or Contract so prepaid for the number of days in the month actually elapsed
up to the date of the prepayment.  Generally,  the effect of prepayments in full
will be to reduce the amount of interest paid in the following  month to holders
of Securities entitled to payments of interest because interest on the principal
amount of any Mortgage Loan or Contract so prepaid will be paid only to the date
of prepayment rather than for a full month. A partial prepayment of principal is
generally  applied  so as to reduce  the  outstanding  principal  balance of the
related  Mortgage Loan or Contract as of the Due Date in the month in which such
partial prepayment is received.

      The timing of changes in the rate of principal  payments on the Assets 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 such 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
given period may not be offset by a subsequent  like  decrease (or  increase) in
the rate of principal payments.

      The Securityholder  will bear the risk of being able to reinvest principal
received in respect of a Security at a yield at least equal to the yield on such
Security.

Prepayments--Maturity and Weighted Average Life

      The rates at which principal  payments are received on the Assets included
in or  comprising a Trust Fund and the rate at which  payments are made from any
credit  support or Cash Flow  Agreement for the related Series of Securities may
affect the ultimate maturity and the weighted average life of each Class of such
Series.  Prepayments on the Mortgage Loans or Contracts comprising or underlying
the Assets in a  particular  Trust Fund will  generally  accelerate  the rate at
which  principal is paid on some or all of the Classes of the  Securities of the
related Series.

      If so provided in the  prospectus  supplement  for a Series of Securities,
one or more Classes of Securities may have a final scheduled  Distribution Date,
which  is the  date on or  prior  to which  the  stated  principal  amount  (the
"Security  Balance")  thereof is scheduled to be reduced to zero,  calculated on
the basis of the  assumptions  applicable  to such  Series  set  forth  therein.
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 such security
will be  repaid  to the  investor.  The  weighted  average  life  of a Class  of
Securities of a Series will be influenced by the rate at which  principal on the
Assets is paid to such 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 Securities may be affected
by the  varying  maturities  of the Assets in a Trust  Fund.  If any Assets in a
particular  Trust Fund have actual terms to maturity  less than those assumed in
calculating final scheduled  Distribution Dates for the Classes of Securities of
the related  Series,  one or more Classes of such  Securities  may be fully paid
prior  to 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  Interest  Rates or
Contract Rates and  maturities of the Mortgage Loans or Contracts  comprising or
underlying such Assets. See "Description of the Trust Funds."

      Prepayments on loans are also commonly  measured  relative to a prepayment
standard or model,  such as the  Constant  Prepayment  Rate  ("CPR")  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
such loans.

                                       27



      Neither CPR 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  with respect to each Series of Securities may
contain tables, if applicable, setting forth the projected weighted average life
of each Class of Offered  Securities  of such Series and the  percentage  of the
initial  Security  Balance  of each such  Class  that  would be  outstanding  on
specified  Distribution Dates based on the assumptions stated in such 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 or such other standard  specified in such prospectus
supplement.   Such  tables  and  assumptions  are  intended  to  illustrate  the
sensitivity of the weighted average life of the Securities 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 Securities.
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
or any other rate specified in the related prospectus supplement.

Other Factors Affecting Weighted Average Life

      Type of Asset

      If so specified in the related prospectus supplement, a number of Mortgage
Loans  may  have  balloon  payments  due  at  maturity  (which,   based  on  the
amortization  schedule of such Mortgage Loans, may be a substantial amount), and
because the  ability of a mortgagor  to make a balloon  payment  typically  will
depend  upon 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,
without  limitation,  real estate values, the mortgagor's  financial  situation,
prevailing  mortgage loan interest rates, the mortgagor's  equity in the related
Mortgaged  Property,  tax laws and prevailing general economic  conditions.  The
applicable  prospectus  supplement will specify if the Depositor,  the Servicer,
the Master  Servicer,  or any of their affiliates will be obligated to refinance
or repurchase any Mortgage Loan or to sell the Mortgaged  Property.  In the case
of  defaults,  recovery of  proceeds  may be delayed  by,  among  other  things,
bankruptcy  of the  mortgagor  or adverse  conditions  in the  market  where the
property is located.  In order to minimize  losses on defaulted  Mortgage Loans,
the  Servicer  may, to the extent and under the  circumstances  set forth in the
related prospectus supplement, be permitted to 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  Securities
and may thereby lengthen the period of time elapsed from the date of issuance of
a Security until it is retired.

      With respect to certain Mortgage Loans,  including ARM Loans, the Mortgage
Interest  Rate at  origination  may be below the rate that  would  result if the
index and margin relating  thereto were applied at origination.  With respect to
certain Contracts,  the Contract Rate may be "stepped up" during its term or may
otherwise vary or be adjusted.  Under the applicable underwriting standards, the
mortgagor or obligor  under each  Mortgage  Loan or Contract  generally  will be
qualified on the basis of the Mortgage  Interest Rate or Contract Rate in effect
at origination.  The repayment of any such Mortgage Loan or Contract may thus be
dependent  on the  ability of the  mortgagor  or obligor  to make  larger  level
monthly  payments  following  the  adjustment  of the Mortgage  Interest Rate or
Contract Rate. In addition,  certain  Mortgage Loans may be subject to temporary
buydown plans ("Buydown  Mortgage Loans") pursuant to which the monthly payments
made by the  mortgagor  during the early years of the Mortgage Loan will be less
than the scheduled monthly payments thereon (the "Buydown Period"). The periodic
increase in the amount paid by the  mortgagor of a Buydown  Mortgage Loan during
or at the end of the applicable  Buydown  Period may create a greater  financial
burden for the mortgagor, who might not have otherwise qualified for a mortgage,
and may  accordingly  increase  the risk of default  with respect to the related
Mortgage Loan.

      The  Mortgage  Interest  Rates on certain  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 Interest Rates are generally lower than the
sum of the  applicable  index at  origination  and the related  margin over such
index at which interest accrues), the amount of interest

                                       28



accruing on the principal  balance of such Mortgage  Loans may exceed the amount
of the minimum scheduled monthly payment thereon.  As a result, a portion of the
accrued  interest on negatively  amortizing  Mortgage  Loans may be added to the
principal  balance  thereof and will bear  interest at the  applicable  Mortgage
Interest  Rate.  The  addition of any such  deferred  interest to the  principal
balance of any related Class or Classes of Securities will lengthen the weighted
average  life  thereof  and may  adversely  affect  yield  to  holders  thereof,
depending upon the price at which such Securities  were purchased.  In addition,
with  respect to certain ARM Loans  subject to negative  amortization,  during a
period of  declining  interest  rates,  it might be expected  that each  minimum
scheduled  monthly  payment on such a Mortgage  Loan would  exceed the amount of
scheduled  principal and accrued interest on the principal balance thereof,  and
since such excess will be applied to reduce the principal balance of the related
Class or Classes of  Securities,  the weighted  average life of such  Securities
will be reduced and may  adversely  affect yield to holders  thereof,  depending
upon the price at which such Securities were purchased.

      As may be described in the related prospectus  supplement,  the applicable
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  Mortgage  Loans  during a specified  period
(rather than used to fund payments of principal to  Securityholders  during such
period)  with the result that the related  securities  possess an  interest-only
period, also commonly referred to as a revolving period,  which will be followed
by an amortization  period. Any such interest-only or revolving period may, upon
the  occurrence  of certain  events to be  described  in the related  prospectus
supplement, terminate prior to the end of the specified period and result in the
earlier than expected amortization of the related Securities.

      In addition, and as may be described in the related prospectus supplement,
the  related  Agreement  may  provide  that all or a portion  of such  collected
principal  may be  retained  by the  Trustee  (and  held  in  certain  temporary
investments,  including  Mortgage  Loans) for a specified  period prior to being
used to fund payments of principal to Securityholders.

      The result of such  retention and  temporary  investment by the Trustee of
such principal would be to slow the amortization rate of the related  Securities
relative to the  amortization  rate of the related Mortgage Loans, or to attempt
to match the  amortization  rate of the related  Securities  to an  amortization
schedule  established at the time such  Securities are issued.  Any such feature
applicable to any  Securities  may terminate upon the occurrence of events to be
described in the related prospectus supplement, resulting in the current funding
of principal payments to the related  Securityholders and an acceleration of the
amortization of such Securities.

      Termination

      If so  specified  in  the  related  prospectus  supplement,  a  Series  of
Securities may be subject to optional early  termination  through the auction or
repurchase  of some or all of the Assets in the related  Trust Fund by the party
specified  therein  (which  may be a  Securityholder),  on any date on which the
aggregate  principal balance of the Assets or the aggregate  Security Balance of
the Securities of such Series declines to a percentage  specified in the related
prospectus  supplement  (not to exceed 10%) of the aggregate  initial  principal
balance of such Assets or initial Security  Balance of such  Securities,  as the
case may be,  under the  circumstances  and in the  manner  set  forth  therein;
however,  any such optional  termination  or redemption  will be permitted  only
pursuant to a  "qualified  liquidation,"  as defined  under  Section 860F of the
Internal  Revenue Code of 1986, as amended.  In addition,  if so provided in the
related prospectus supplement, certain Classes of Securities 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 Securities.
In general,  defaults on mortgage  loans or contracts are expected to occur with
greater  frequency in their early years.  The rate of default on Mortgage  Loans
which 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 and Contracts will be affected by the general
economic  condition  of the region of the country in which the related  Mortgage
Properties or Manufactured Homes are located. The risk of delinquencies and loss
is

                                       29



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 Securities.

      Refinancing

      At the request of a mortgagor, the Servicer may allow the refinancing of a
Mortgage  Loan or Contract in any Trust Fund by accepting a  prepayment  in full
and  permitting  a new loan secured by a mortgage on the same  property.  In the
event of such a  refinancing,  the new loan would not be included in the related
Trust Fund and,  therefore,  such  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.  Such
programs may  include,  without  limitation,  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 such Mortgage
Loans or Contracts.

      Due-on-Sale Clauses

      Acceleration  of  mortgage  payments as a result of certain  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  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.  With  respect to any Mortgage  Loans,  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
which  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 the Servicer upon any such 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  certain  cases,  the  transfer  may be  made  by a
delinquent obligor in order 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 the related Contract, the Servicer's ability to do
so  will  depend  on the  enforceability  under  state  law of the  "due-on-sale
clause." See "Certain Legal Aspects of the  Contracts--Transfers of Manufactured
Homes; Enforceability of Due-on-Sale Clauses."

      The  Depositor  is a direct  wholly-owned  subsidiary  of Banc of  America
Mortgage  Capital  Corporation and was  incorporated in the State of Delaware on
July 23, 1997. The principal  executive  offices of the Depositor are located at
214 North Tryon Street, Charlotte, North Carolina 28255. Its telephone number is
(704) 386-2400.

      The  Depositor  will  have  limited  obligations  and  rights  under  each
Agreement after the Closing Date for any Series.

                                       30



      The  Depositor  and  any  director,  officer,  employee  or  agent  of the
Depositor  shall be indemnified by the Trust Fund and held harmless  against any
loss, liability or expense incurred in connection with any legal action relating
to the applicable Agreement or the Securities, other than any loss, liability or
expense  related  to any  specific  Asset or Assets and any loss,  liability  or
expense  incurred by reason of willful  misfeasance,  bad faith or negligence in
the  performance  of its duties under the  applicable  Agreement or by reason of
reckless disregard of its obligations and duties under such Agreement.

      To the extent Bank of America is not the Sponsor of a Series,  information
regarding the Depositor's securitization program will be provided in the related
prospectus supplement.

      The Depositor does not have, nor is it expected in the future to have, any
significant assets.

                                   THE SPONSOR

      Bank of  America,  National  Association  ("Bank of  America")  or another
entity which will be named in the applicable  prospectus  supplement will act as
the Sponsor of a particular Series of Securities.

      The  Depositor's  securitization  program  principally  is used to finance
portfolios of sub-prime  mortgage loans secured by first or junior liens on one-
to  four-family  residential  properties  acquired  by  Bank of  America  or its
affiliates from third parties. The Depositor's  securitization  program may also
be used by third  parties that are not Bank of America  affiliates to securitize
mortgage loans on a  "rent-a-shelf"  basis,  whereby a third party transfers the
mortgage  loans  to  the  Depositor  simultaneously  with  the  transfer  by the
Depositor  of the  mortgage  loans to the  applicable  Trust and issuance of the
related  Series of  Securities.  In that event,  the  unaffiliated  third party,
rather than Bank of America, will be the Sponsor of the transaction.

                          DESCRIPTION OF THE SECURITIES

General

      A separate  common law trust  will  serve as the  Issuing  Entity and will
issue the asset-backed  certificates (the  "Certificates")  of a series (each, a
"Series")  (including  any  Class  of  Certificates  not  offered  hereby).  The
Certificates  will  represent the entire  beneficial  ownership  interest in the
trust fund (the "Trust" or the "Trust Fund") created  pursuant to the applicable
Agreement.  If a Series of Securities  includes  asset-backed notes (the "Notes"
and,  together  with  the  Certificates,  the  "Securities"),  such  Notes  will
represent  indebtedness of the related Trust Fund and will be issued and secured
pursuant to an Indenture.  Each Series of Securities will consist of one or more
classes (each, a "Class") of Securities  that may (i) provide for the accrual of
interest thereon based on fixed,  variable or adjustable  rates;  (ii) be senior
(the "Senior  Certificates"  or the "Senior  Notes" and,  collectively,  "Senior
Securities")  or subordinate  (the  "Subordinated  Certificates"  or the "Senior
Notes"  and,  collectively,  "Subordinated  Securities")  to one or  more  other
Classes of Securities  in respect of certain  distributions  on the  Securities;
(iii) be entitled either to (A) principal distributions, with disproportionately
low, nominal or no interest  distributions or (B) interest  distributions,  with
disproportionately  low,  nominal or no principal  distributions  (collectively,
"Strip Securities");  (iv) provide for distributions of accrued interest thereon
commencing  only  following  the  occurrence  of  certain  events,  such  as the
retirement   of  one  or  more  other  Classes  of  Securities  of  such  Series
(collectively,  "Accrual Securities");  (v) provide for payments of principal as
described in the related  prospectus  supplement,  from all or only a portion of
the Assets in such Trust Fund, to the extent of available funds, in each case as
described  in  the  related  prospectus  supplement;  and/or  (vi)  provide  for
distributions  based on a combination of two or more components thereof with one
or more of the  characteristics  described in this  paragraph  including a Strip
Security  component.  If so  specified  in the  related  prospectus  supplement,
distributions on one or more Classes of a Series of Securities may be limited to
collections  from a designated  portion of the Assets in the related  Trust Fund
(each such portion of Assets,  an "Asset  Group").  Any such Classes may include
Classes of  Securities of a Series  offered  pursuant to this  prospectus  and a
related prospectus supplement (the "Offered Securities" ).

      Each Class of  Offered  Securities  of a Series  will be issued in minimum
denominations  corresponding to the Security Balances or, in the case of certain
Classes of Strip Securities,  notional amounts or percentage interests specified
in the related prospectus supplement. The transfer of any Offered Securities may
be registered and such  Securities  may be exchanged  without the payment of any
service  charge  payable in  connection  with such  registration  of transfer or
exchange,  but the  Depositor  or the  Trustee or any agent  thereof may require
payment of a sum sufficient to cover any tax or other  governmental  charge. One
or more  Classes of  Securities  of a Series may be issued in fully  registered,
certificated form  ("Definitive  Securities") or in book-entry form ("Book-Entry
Securities"),  as  provided  in the  related  prospectus  supplement.  See "Risk
Factors--Risks  Associated with the Securities--Book-Entry  System  for  Certain
Classes of Securities May Decrease Liquidity and Delay Payment" and "Description
of  the   Securities--Book-Entry   Registration   and  Definitive   Securities."
Definitive  Securities  will be  exchangeable  for other  Securities of the same
Class and  Series  of a like  aggregate  Security  Balance,  notional  amount or
percentage  interest  but  of  different  authorized  denominations.  See  "Risk
Factors--Risks Associated with the Securities--Securities May Not be Liquid."

Distributions

      Distributions  on the  Securities  of  each  Series  will be made by or on
behalf of the  Trustee on each  Distribution  Date as  specified  in the related
prospectus supplement from the Available Distribution Amount for such Series and
such Distribution Date.  Distributions  (other than the final distribution) will
be made to the persons in whose names the Securities are registered at the close
of business on the date  specified  in the related  prospectus  supplement  (the
"Record Date"), and the amount of each distribution will be determined as of the
close of business on the date  specified  in the related  prospectus  supplement
(the  "Determination  Date").  All  distributions  with respect to each Class of
Securities  on each  Distribution  Date  will be  allocated  pro rata  among the
outstanding Securityholders in such Class or by random selection or as described
in the  related  prospectus  supplement.  Payments  will be made  either by wire
transfer in immediately  available funds to the account of a Securityholder at a

                                       32



bank  or  other  entity  having  appropriate   facilities   therefor,   if  such
Securityholder has so notified the Trustee or other person required to make such
payments no later than the date specified in the related  prospectus  supplement
(and, if so provided in the related prospectus  supplement,  holds Securities in
the requisite  amount specified  therein),  or by check mailed to the address of
the person entitled  thereto as it appears on the security  register;  provided,
however,  that the final  distribution  in retirement of the Securities  will be
made only upon  presentation  and  surrender of the  Securities  at the location
specified in the notice to Securityholders of such final distribution.

Available Distribution Amount

      All  distributions  on the Securities of each Series on each  Distribution
Date will be made from the Available  Distribution  Amount  described  below, in
accordance  with the  terms  described  in the  related  prospectus  supplement.
Generally, the "Available Distribution Amount" for each Distribution Date equals
the sum of the following amounts:

      (i)    the total  amount of all cash on deposit in the related  Collection
Account as of the corresponding Determination Date, exclusive of:

            (a)   all scheduled payments of principal and interest collected but
      due on a date subsequent to the related  Collection  Period (a "Collection
      Period" with respect to any  Distribution  Date generally will commence on
      the  second  day  of  the  month  in  which  the   immediately   preceding
      Distribution Date occurs, or the day after the Cut-off Date in the case of
      the first Collection Period, and will end on the first day of the month of
      the related Distribution Date),

            (b)   all  prepayments,   together  with  related  payments  of  the
      interest  thereon  and related  Prepayment  Charges,  all  proceeds of any
      insurance  policies  to be  maintained  in  respect  of each Asset (to the
      extent such  proceeds are not applied to the  restoration  of the Asset or
      released in accordance with the normal servicing procedures of a Servicer,
      subject  to the terms and  conditions  applicable  to the  related  Asset)
      (collectively,  "Insurance  Proceeds"),  all other  amounts  received  and
      retained in connection  with the  liquidation  of Assets in default in the
      Trust Fund  ("Liquidation  Proceeds"),  and other  unscheduled  recoveries
      received subsequent to the related Collection Period,

            (c)   all  amounts  in  the  Collection  Account  that  are  due  or
      reimbursable to the Depositor,  the Trustee,  an Asset Seller, a Servicer,
      the  Master  Servicer  or any other  entity as  specified  in the  related
      prospectus  supplement or that are payable in respect of certain  expenses
      of the related Trust Fund, and

            (d)   all amounts  received  for a  repurchase  of an Asset from the
      Trust Fund for defective  documentation or a breach of  representation  or
      warranty received subsequent to the related Collection Period;

      (ii)   if the related  prospectus  supplement  so  provides,  interest  or
investment income on amounts on deposit in the Collection Account, including any
net amounts paid under any Cash Flow Agreements;

      (iii)  all advances made by a Servicer or the Master Servicer or any other
entity as specified in the related  prospectus  supplement  with respect to such
Distribution Date;

      (iv)   if and to the extent the related prospectus supplement so provides,
amounts  paid by a Servicer  or any other  entity as  specified  in the  related
prospectus  supplement  with  respect  to  interest  shortfalls  resulting  from
prepayments during the related Prepayment Period; and

      (v)    to  the  extent not on deposit in the related Collection Account as
of the corresponding Determination Date, any amounts collected under, from or in
respect of any credit support with respect to such Distribution Date.

                                       33



      As  described  below,  the entire  Available  Distribution  Amount will be
distributed among the related  Securities  (including any Securities not offered
hereby) on each  Distribution  Date, and  accordingly  will be released from the
Trust Fund and will not be available for any future distributions.

      The related prospectus supplement for a Series of Securities will describe
any variation in the calculation of the Available  Distribution  Amount for such
Series.

Distributions of Interest on the Securities

      Each Class of Securities (other than Classes of Strip Securities that have
no Pass-Through Rate or interest rate) may have a different Pass-Through Rate or
interest  rate,  which will be a fixed,  variable  or  adjustable  rate at which
interest  will accrue on such Class or a Component  thereof  (the  "Pass-Through
Rate"). The related prospectus  supplement will specify the Pass-Through Rate or
interest  rate for each  Class or  component  or, in the case of a  variable  or
adjustable  Pass-Through  Rate or interest rate, the method for  determining the
Pass-Through  Rate or interest  rate.  The related  prospectus  supplement  will
specify whether interest on any Class of Securities will be calculated either on
the basis of a 360-day year  consisting  of twelve 30-day months or on the basis
of the actual  number of days in the  Interest  Accrual  Period and on a 360-day
year or another method specified in the such prospectus supplement.

      Distributions  of interest in respect of the  Securities 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  commencing only on
the  Distribution  Date,  or under the  circumstances,  specified in the related
prospectus  supplement,  and any Class of Strip Securities that are not entitled
to any  distributions  of interest) based on the Accrued  Security  Interest for
such Class and such Distribution Date, subject to the sufficiency of the portion
of  the  Available   Distribution   Amount  allocable  to  such  Class  on  such
Distribution  Date.  Prior to the time interest is distributable on any Class of
Accrual   Securities,   the  amount  of  Accrued  Security  Interest   otherwise
distributable  on such Class will be added to the  Security  Balance  thereof on
each  Distribution  Date.  With  respect  to each Class of  Securities  and each
Distribution  Date (other than certain  Classes of Strip  Securities),  "Accrued
Security Interest" will be equal to interest accrued during the related Interest
Accrual Period on the outstanding  Security Balance thereof immediately prior to
the  Distribution  Date, at the applicable  Pass-Through  Rate or interest rate,
reduced as described  below.  Accrued  Security  Interest on certain  Classes of
Strip  Securities will be equal to interest  accrued during the related Interest
Accrual Period on the outstanding  notional amount thereof  immediately prior to
each  Distribution  Date, at the applicable  Pass-Through Rate or interest rate,
reduced as described  below, or interest  accrual in the manner described in the
related prospectus supplement. The method of determining the notional amount for
a certain Class of Strip Securities will be described in the related  prospectus
supplement.  Reference to notional  amount is solely for  convenience in certain
calculations  and does not represent the right to receive any  distributions  of
principal. Accrued Security Interest on a Series of Securities generally will be
reduced in the event of prepayment interest shortfalls,  which are shortfalls in
collections  of interest  for a full  Interest  Accrual  Period  resulting  from
prepayments  prior  to the due  date  in such  Interest  Accrual  Period  on the
Mortgage  Loans or Contracts  comprising or  underlying  the Assets in the Trust
Fund for such Series.  The particular  manner in which such shortfalls are to be
allocated  among some or all of the Classes of Securities of that Series will be
specified  in  the  related  prospectus   supplement.   The  related  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  Securities  may be  reduced  as a result  of any  other  contingencies,
including  delinquencies,  losses and deferred  interest on or in respect of the
Mortgage  Loans or Contracts  comprising or underlying the Assets in the related
Trust Fund. Any reduction in the amount of Accrued Security  Interest  otherwise
distributable on a Class of Securities by reason of the allocation to such Class
of a  portion  of any  deferred  interest  on the  Mortgage  Loans or  Contracts
comprising  or underlying  the Assets in the related  Trust Fund will  generally
result in a corresponding  increase in the Security  Balance of such Class.  See
"Risk  Factors--Risk  Associated  with the  Securities--Rate  of  Prepayment  on
Mortgage Loans May Adversely  Affect Average Lives and Yields on the Securities"
and "Yield Considerations."

Distributions of Principal of the Securities

      The  Securities  of each  Series,  other  than  certain  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 in respect of

                                       34



principal out of the future cash flow on the Assets and other assets included in
the related Trust Fund. The outstanding  Security  Balance of a Security will be
reduced to the extent of  distributions  of principal  thereon from time to time
and, if and to the extent so provided in the related prospectus  supplement,  by
the amount of losses incurred in respect of the related Assets, may be increased
in respect of  deferred  interest on the  related  Mortgage  Loans to the extent
provided  in the  related  prospectus  supplement  and,  in the case of  Accrual
Securities prior to the Distribution Date on which distributions of interest are
required  to  commence,  will  be  increased  by any  related  Accrued  Security
Interest.  If so specified  in the related  prospectus  supplement,  the initial
aggregate  Security  Balance of all  Classes of  Securities  of a Series will be
greater than the outstanding  aggregate  principal balance of the related Assets
as of the applicable  Cut-off Date. The initial aggregate  Security Balance of a
Series  and each Class  thereof  will be  specified  in the  related  prospectus
supplement. Distributions of principal will be made on each Distribution Date to
the Class or Classes of  Securities  in the amounts and in  accordance  with the
priorities  specified in the related prospectus  supplement.  Certain Classes of
Strip Securities with no Security Balance are not entitled to any  distributions
of principal.

Categories of Classes of Securities

      The Securities of any Series may be comprised of one or more Classes. Such
Classes,  in  general,  fall into  different  categories.  The  following  chart
identifies and generally  defines  certain of the more typical  categories.  The
prospectus  supplement for a Series of Securities may identify the Classes which
comprise  such  Series by  reference  to the  following  categories  or  another
category specified in the applicable prospectus supplement.

Categories of Classes                     Definition

                                          PRINCIPAL TYPES

Accretion Directed Class                  A Class that receives principal
                                          payments from the accreted interest
                                          from specified Accrual Classes. An
                                          Accretion Directed Class also may
                                          receive principal payments from
                                          principal paid on the Assets for the
                                          related Series.

Component Class                           A Class consisting of two or more
                                          specified components (each, a
                                          "Component") as described in the
                                          applicable prospectus supplement. The
                                          Components of a Class may have
                                          different principal and/or interest
                                          payment characteristics but together
                                          constitute a single Class and do not
                                          represent severable interests. Each
                                          Component may be identified as falling
                                          into one or more of the categories in
                                          this chart.

Lockout Class                             A senior Class that is designed not to
                                          participate in or to participate to a
                                          limited extent in (i.e., to be "locked
                                          out" of), for a specified period, the
                                          receipt of (1) principal prepayments
                                          on the Assets that are allocated
                                          disproportionately to the senior
                                          Classes of such Series as a group
                                          pursuant to a "shifting interest"
                                          structure and/or (2) scheduled
                                          principal payments on the Assets that
                                          are allocated to the senior Classes as
                                          a group. A Lockout Class will
                                          typically not be entitled to receive,
                                          or will be entitled to receive only a
                                          restricted portion of, distributions
                                          or principal prepayments and/or
                                          scheduled principal payments, as
                                          applicable, for a period of several
                                          years, during which time all or a
                                          portion of such principal payments
                                          that it would otherwise be entitled to
                                          receive in the absence of a "lockout"
                                          structure will be distributed in
                                          reduction of the principal balances of
                                          other senior Classes. Lockout Classes
                                          are designed to minimize weighted
                                          average life volatility during the
                                          lockout period.

                                       35



Notional Amount Class                     A Class having no principal balance
                                          and bearing interest on the related
                                          notional amount. The notional amount
                                          is used for purposes of the
                                          determination of interest
                                          distributions.

Pass-Through Class                        A Class of Senior Securities that is
                                          entitled to receive all or a specified
                                          percentage of the principal payments
                                          that are distributable to the Senior
                                          Securities or applicable group of
                                          Senior Securities (other than any
                                          Ratio Strip Class) in the aggregate on
                                          each Distribution Date until the
                                          Security Balances of all the Senior
                                          Securities or applicable group of
                                          Senior Securities are reduced to zero
                                          and that is not designated as a
                                          Sequential Pay Class.

Planned Amortization Class                A Class that is designed to receive
(also sometimes referred to as a "PAC")   principal payments using a
                                          predetermined principal balance
                                          schedule derived by assuming two
                                          constant prepayment rates for the
                                          underlying Assets. These two rates are
                                          the endpoints for the "structuring
                                          range" for the Planned Amortization
                                          Class. The Planned Amortization
                                          Classes in any Series of Securities
                                          may be subdivided into different
                                          categories (e.g., Planned Amortization
                                          Class I ("PAC I"), Planned
                                          Amortization Class II ("PAC II") and
                                          so forth) derived using different
                                          structuring ranges and/or payment
                                          priorities. A PAC is designed to
                                          provide protection against volatility
                                          of weighted average life if
                                          prepayments occur at a constant rate
                                          within the structuring range.

Ratio Strip Class                         A Class that is entitled to receive a
                                          constant proportion, or "ratio strip,"
                                          of the principal payments on the
                                          underlying Assets.

Scheduled Amortization Class              A Class that is designed to receive
                                          principal payments using a
                                          predetermined principal balance
                                          schedule but is not designated as a
                                          Planned Amortization Class or Targeted
                                          Amortization Class. The schedule is
                                          derived by assuming either two
                                          constant prepayment rates or a single
                                          constant prepayment rate for the
                                          underlying Assets. In the former case,
                                          the two rates are the endpoints for
                                          the "structuring range" for the
                                          Scheduled Amortization Class and such
                                          range generally is narrower than that
                                          for a Planned Amortization Class.
                                          Typically, the Support Class(es) for
                                          the applicable Series of Securities
                                          generally will represent a smaller
                                          percentage of the Scheduled
                                          Amortization Class than a Support
                                          Class generally would represent in
                                          relation to a Planned Amortization
                                          Class or a Targeted Amortization
                                          Class. A Scheduled Amortization Class
                                          is generally less sensitive to
                                          weighted average life volatility as a
                                          result of prepayments than a Support
                                          Class but more sensitive than a
                                          Planned Amortization Class or a
                                          Targeted Amortization Class.

Senior Securities                         Classes that are entitled to receive
                                          payments of principal and interest on
                                          each Distribution Date prior to the

                                          sequence, that does not have a
                                          predetermined principal balance
                                          schedule and that, in most cases, is
                                          entitled to receive payments of
                                          principal continuously from the first
                                          Distribution Date on which it receives
                                          principal until it is retired. A

                                          payments before or after other Classes
                                          in the same Series of Securities may
                                          be identified as a Sequential Pay
                                          Class.

Subordinated Securities                   Classes that are entitled to receive
                                          payments of principal and interest on
                                          each Distribution Date only after the
                                          Senior Securities and certain Classes
                                          of Subordinated Securities with higher
                                          priority of distributions have
                                          received their full principal and
                                          interest entitlements.

Super Senior Class                        A Class of Senior Securities that will
                                          not bear its share of certain losses
                                          or is not allocated certain losses
                                          after the Classes of Subordinated
                                          Securities are no longer outstanding
                                          and one or more specified Classes of
                                          Senior Securities bear such losses.

Super Senior Support Class                A Class of Senior Securities that
                                          bears certain losses allocated to one
                                          or more Classes of Senior Securities
                                          or is allocated certain losses while
                                          one or more Classes of Senior
                                          Securities are not allocated losses.

Support Class (also sometimes             A Class that is entitled to receive
referred to as a "Companion Class")       principal payments on any Distribution
                                          Date only if scheduled payments have
                                          been made on specified Planned
                                          Amortization Classes, Targeted
                                          Amortization Classes and/or Scheduled
                                          Amortization Classes.

Targeted Amortization  Class              A Class that is designed to receive
(also sometimes referred to as a "TAC")   principal payments using a
                                          predetermined principal balance
                                          schedule derived by assuming a single
                                          constant prepayment rate for the
                                          underlying Assets. A TAC is designed
                                          to provide some protection against
                                          shortening of weighted average life if
                                          prepayments occur at a rate exceeding
                                          the assumed constant prepayment rate
                                          used to derive the principal balances
                                          schedule of such Class.

                                                      INTEREST TYPES

Accrual Class                             A Class that accretes the amount of
                                          accrued interest otherwise
                                          distributable on such Class, which
                                          amount will be added as principal to
                                          the principal balance of such Class on
                                          each applicable Distribution Date.
                                          Such accretion may continue until some
                                          specified event has occurred or until
                                          such Accrual Class is retired.

Fixed Rate Class                          A Class with an interest rate that is
                                          fixed throughout the life of the
                                          Class.

Floating Rate Class                       A Class with an interest rate that
                                          resets periodically based upon a
                                          designated index and that varies
                                          directly with changes in such index.

Interest Only Class                       A Class that is entitled to receive
                                          some or all of the interest payments
                                          made on the Assets and little or no
                                          principal. Interest Only Classes have
                                          either no principal balance, a nominal
                                          principal balance or a notional
                                          amount. A nominal principal balance
                                          represents actual principal that will
                                          be paid on the Class. It is referred
                                          to as nominal since it is extremely
                                          small compared

                                       37



                                          to other Classes. A notional amount is
                                          the amount used as a reference to
                                          calculate the amount of interest due
                                          on an Interest Only Class that is not
                                          entitled to any distributions in
                                          respect of principal.

Inverse  Floating Rate Class              A Class with an interest rate that
                                          resets periodically based upon a
                                          designated index and that varies
                                          inversely with changes in such index
                                          and with changes in the interest rate
                                          payable on the related Floating Rate
                                          Class.

Prepayment Charge Class                   A Class that is only entitled to
                                          penalties or premiums, if any, due in
                                          connection with a full or partial
                                          prepayment of an Asset.

Principal Only Class                      A Class that does not bear interest
                                          and is entitled to receive only
                                          distributions in respect of principal.

Step Coupon Class                         A Class with a fixed interest rate
                                          that is reduced to a lower fixed rate
                                          after a specific period of time. The
                                          difference between the initial
                                          interest rate and the lower interest
                                          rate will be supported by a reserve
                                          fund established on the Closing Date.

Variable Rate Class                       A Class with an interest rate that
                                          resets periodically and is calculated
                                          by reference to the rate or rates of
                                          interest applicable to the Assets.

Components

      To the extent specified in the related prospectus supplement, distribution
on a Class of Securities  may be based on a combination of two or more different
Components  as  described  under   "--General"   above.  To  such  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 such a Class of  Securities.  In such case,  reference  in such  sections  to
Security Balance and  Pass-Through  Rate or interest rate refer to the principal
balance,  if any, of any such  Component and the  Pass-Through  Rate or interest
rate, if any, on any such Component, respectively.

Distributions on the Securities of Prepayment Charges

      If so provided in the related  prospectus  supplement,  Prepayment Charges
that are  collected  on the  Mortgage  Loans in the  related  Trust Fund will be
distributed  on each  Distribution  Date to the Class or Classes  of  Securities
entitled thereto in accordance with the provisions  described in such prospectus
supplement.

Allocation of Losses and Shortfalls

      If so provided in the  prospectus  supplement  for a Series of  Securities
consisting  of  one  or  more  Classes  of  Subordinated   Securities,   on  any
Distribution Date in respect of which losses or shortfalls in collections on the
Assets have been incurred, the amount of such losses or shortfalls will be borne
first by a Class of  Subordinated  Securities  in the  priority  and  manner and
subject  to  the  limitations  specified  in  such  prospectus  supplement.  See
"Description  of Credit  Support" for a  description  of the types of protection
that may be included in a Trust Fund  against  losses and  shortfalls  on Assets
comprising such Trust Fund.

Advances in Respect of Delinquencies

      With respect to any Series of Securities evidencing an interest in a Trust
Fund,  if so provided  in the related  prospectus  supplement,  the  Servicer or
another  entity  described  therein  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  Collection  Account  that are not  included in the  Available
Distribution Amount for such Distribution Date, in an amount equal to the

                                       38



aggregate  of  payments of  principal  (other  than any  balloon  payments)  and
interest (net of related servicing fees and Retained  Interest) that were due on
the Assets in such Trust Fund  during  the  related  Collection  Period and were
delinquent on the related  Determination  Date,  subject to the  Servicer's  (or
another  entity's)  good  faith   determination   that  such  advances  will  be
reimbursable  from Related Proceeds (as defined below).  In the case of a Series
of Securities that includes one or more Classes of  Subordinated  Securities and
if so provided in the related prospectus supplement,  the Servicer's (or another
entity's)  advance  obligation  may be  limited  only  to the  portion  of  such
delinquencies  necessary  to  make  the  required  distributions  on one or more
Classes of Senior Securities and/or may be subject to the Servicer's (or another
entity's) good faith  determination  that such advances will be reimbursable not
only from Related  Proceeds but also from  collections on other Assets otherwise
distributable  on one or more  Classes  of  such  Subordinated  Securities.  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  Securities  entitled
thereto,  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 such advances were made (as to any Assets,  "Related
Proceeds")  and from any  other  amounts  specified  in the  related  prospectus
supplement,  including out of any amounts otherwise distributable on one or more
Classes of Subordinated Securities of such Series;  provided,  however, that any
such advance will be  reimbursable  from any amounts in the  Collection  Account
prior to any  distributions  being made on the Securities to the extent that the
Servicer (or such other entity) shall determine,  based on its estimation of the
value of the Mortgaged  Property or Manufactured  Home in relation to the sum of
the unpaid principal balance of the related Asset, accrued interest,  the amount
of previously  unreimbursed Advances and anticipated  disposition expenses, that
such advance (a  "Nonrecoverable  Advance") is not ultimately  recoverable  from
Related  Proceeds or, if applicable,  from collections on other Assets otherwise
distributable on such Subordinated Securities. If advances have been made by the
Servicer from excess funds in the Collection  Account,  the Servicer is required
to replace such funds in the Collection Account on any future  Distribution Date
to the extent that funds in the Collection Account on such Distribution Date are
less than payments  required to be made to  Securityholders  on such date. If so
specified in the related prospectus supplement,  the obligations of the Servicer
(or another  entity) to make advances may be secured by an advance  facility,  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 obligor on, any such surety  bond,  will be set forth in
the related prospectus supplement.

      If specified in the related prospectus supplement,  the Master Servicer or
the Trustee  will be required to make  advances,  subject to certain  conditions
described in the prospectus supplement, in the event of a Servicer default.

Reports to Securityholders

in  the  related  prospectus  supplement,  will  include  in the  statement  any

prospectus  supplement and, within a reasonable  period of time after the end of
each calendar year, shall furnish to each  Securityholder  of record at any time
during the calendar year such  information  required by the Code and  applicable
regulations  thereunder 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  applicable  Agreement for each Series of
Securities will terminate upon the payment to  Securityholders of that Series of
all  amounts  held  in the  Collection  Account  or by a  Servicer,  the  Master
Servicer,  if any, or the Trustee  and  required to be paid to them  pursuant to
such  Agreement  following  the  earlier  of (i)  the  final  payment  or  other
liquidation of the last Asset subject thereto or the disposition of all property
acquired upon  foreclosure of any Mortgage Loan or Contract  subject thereto and
(ii) upon the  reduction  of the  principal  balance  of all or a portion of the
assets of Trust Fund to a  percentage  specified  in the  applicable  prospectus
supplement,  the  auction or purchase of some or all of such assets of the Trust
Fund  by  the  party   entitled   to  effect  such   termination,   including  a
Securityholder,  under  the  circumstances  and in the  manner  set forth in the
related  prospectus  supplement.  In no  event,  however,  will the  Trust  Fund
continue beyond the date specified in the related prospectus supplement. Written
notice  of  termination  of the  applicable  Agreement  will  be  given  to each
Securityholder,  and the final  distribution will be made only upon presentation
and surrender of the Securities at the location to be specified in the notice of
termination.

                                       41



Definitive Form

      If so  specified in the related  prospectus  supplement,  Securities  of a
Series may be issued as Definitive  Securities.  Distributions  of principal of,
and  interest  on,  Definitive  Securities  will be made  directly to holders of
Definitive  Securities  in  accordance  with  the  procedures  set  forth in the
Agreement.  The Definitive Securities of a Series offered hereby and by means of
the applicable  prospectus  supplement will be transferable  and exchangeable at
the office or agency  maintained  by the  Trustee or such other  entity for such
purpose set forth in the  applicable  prospectus  supplement.  No service charge
will be made for any  transfer  or exchange of  Definitive  Securities,  but the
Trustee or such other entity may require  payment of a sum  sufficient  to cover
any tax or other  governmental  charge  in  connection  with  such  transfer  or
exchange.

      In the event that an  election  is made to treat the Trust Fund (or one or
more pools of segregated  assets  therein) as a REMIC,  the Residual  Securities
thereof will be issued as Definitive Securities. No legal or beneficial interest
in all or a portion of any  Residual  Security  may be  transferred  without the
receipt by the  transferor  and the  Trustee  of an  affidavit  described  under
"--Taxation  of  Owners  of  Residual  Securities--Tax-Related  Restrictions  on
Transfer of Residual Securities."

Book-Entry Registration and Definitive Securities

      Persons acquiring beneficial ownership interests  ("Beneficial Owners") in
the Book-Entry  Securities will hold their Securities  through DTC in the United
States,  or  Clearstream  or Euroclear (in Europe) if they are  participants  of
those systems (the  "Participants"),  or indirectly through  organizations which
are participants in those systems (the "Indirect  Participants").  Each Class of
the  Book-Entry  Securities of a Series  initially will be represented by one or
more physical  certificates  registered in the name of Cede & Co., as nominee of
DTC,  which will be the "holder" or  "Securityholder"  of those  Securities,  as
those terms are used in this prospectus and the applicable prospectus supplement
for a Series.  No Beneficial Owner of a Book-Entry  Security will be entitled to
receive  a  Definitive  Security  representing  that  person's  interest  in the
Book-Entry  Security,  except as set forth  below.  Unless and until  Definitive
Securities  are issued  under the limited  circumstances  described  below,  all
references to actions taken by  Securityholders or holders shall, in the case of
the Book-Entry Securities,  refer to actions taken by DTC upon instructions from
its DTC  Participants,  and all references in this prospectus and the applicable
prospectus  supplement  for a Series  to  distributions,  notices,  reports  and
statements to  Securityholders  or holders shall,  in the case of the Book-Entry
Securities,  refer to distributions,  notices,  reports and statements to DTC or
Cede & Co., as the registered holder of the Book-Entry  Securities,  as the case
may be, for distribution to Beneficial Owners in accordance with DTC procedures.
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  depositaries  which in turn
will hold those positions in customers' securities accounts in the depositaries'
names on the books of DTC.  Citibank will act as depositary for  Clearstream and
JPMorgan Chase Bank,  National  Association will act as depositary for Euroclear
(in those  capacities,  individually the "Relevant  Depositary" and collectively
the  "European  Depositaries").  Investors may hold  beneficial  interest in the
Book-Entry Securities in minimum denominations of $1,000.

      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 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).

      Beneficial  Owners will receive all  distributions  of  principal  of, and
interest  on,  the  Book-Entry  Securities  from  the  Trustee  through  DTC and
Participants.  While the Book-Entry Securities 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  Book-Entry  Securities  and is required to receive and  transmit
distributions  of  principal  of, and interest  on, the  Book-Entry  Securities.
Participants and Indirect Participants with whom Beneficial Owners have accounts
for their  Book-Entry  Securities  are  similarly  required  to make  book-entry
transfers  and  receive  and  transmit  these  distributions  on behalf of their
respective Beneficial Owners. Accordingly, although Beneficial

                                       42



Owners will not possess certificates  representing their respective interests in
the  Book-Entry  Securities,  the Rules provide a mechanism by which  Beneficial
Owners will receive distributions and will be able to transfer their interest.

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

      Because  of time zone  differences,  credits  of  securities  received  in
Clearstream 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
Euroclear or  Clearstream  Participants  on that  following  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  settlement in DTC. For information with respect to tax  documentation
procedures  relating to the Securities see  "--Certain  U.S.  Federal Income Tax
Documentation     Requirements"     below    and     "Federal     Income     Tax
Consequences--REMICs--Taxation  of  Certain  Foreign  Investors"  and  "--Backup
Withholding."

      Transfers  between  Participants  will occur in accordance with the 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
accordance  with the  Rules on  behalf of the  relevant  European  international
clearing  system  by  the  Relevant  Depositary;   however,  these  cross-market
transfers  will  require  delivery  of  instructions  to the  relevant  European
international  clearing  system by the  counterparty in the system in accordance
with its rules and procedures and within 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.
Clearstream Participants and Euroclear Participants may not deliver instructions
directly to the European Depositaries.

      The Depository  Trust Company  ("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 New York
Uniform Commercial Code and a "clearing agency"  registered  pursuant to Section
17A of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). DTC
performs   services  for  its   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
Securities, whether held for its own account or as a nominee for another person.
In general, beneficial ownership of Book-Entry Securities will be subject to the
Rules, as in effect from time to time.

      Clearstream  International,  a Luxembourg limited liability  company,  was
formed in January  2000 through the merger of Cedel  International  and Deutsche
Boerse Clearing.

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

                                       43



      Clearstream  holds  securities for its  Participants  and  facilitates the
clearance and  settlement of securities  transactions  by electronic  book-entry
transfers  between  their  accounts.   Clearstream  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 Euroclear Bank S.A./N.V.  (which operates
Euroclear)  in Brussels to  facilitate  settlement  of trades  between  systems.
Clearstream currently accepts over 200,000 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 2,500 customers located in over 80 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  custodial
relationship with an account holder of Clearstream.

      The  Euroclear  System  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 a variety of currencies,  including United States dollars.  Euroclear
provides 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 Euroclear Bank S.A./N.V. (the "Euroclear Operator").  All operations
are conducted by the Euroclear Operator,  and all Euroclear securities clearance
accounts and Euroclear  cash accounts are accounts with the Euroclear  Operator.
Euroclear  plc   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. These 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 of Euroclear only on behalf of Euroclear Participants,  and
has  no  record  of or  relationship  with  persons  holding  through  Euroclear
Participants.

      Distributions   on  the  Book-Entry   Securities  will  be  made  on  each
Distribution  Date by the Trustee to Cede & Co., as nominee of DTC.  DTC will be
responsible for crediting the amount of these  distributions  to the accounts of
the applicable DTC Participants in accordance with DTC's normal procedures. Each
DTC Participant  will be responsible for disbursing  these  distributions to the
Beneficial  Owners of the Book-Entry  Securities  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 Securities that it represents.

      Under a book-entry format,  Beneficial Owners of the Book-Entry Securities
may experience  some delay in their receipt of payments,  since payments will be
forwarded by the Trustee to Cede & Co.  Distributions with respect to Securities
held through  Clearstream  or Euroclear will be credited to the cash accounts of
Clearstream  Participants  or  Euroclear  Participants  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 "Federal Income Tax
Consequences--REMICs--Taxation  of  Certain  Foreign  Investors"  and  "--Backup
Withholding."  Because  DTC can  only act on  behalf  of DTC  Participants,  the
ability of a  Beneficial  Owner to pledge  Book-Entry  Securities  to persons or
entities that do not  participate  in the depository  system,  or otherwise take
actions regarding their Book-Entry Securities, may be limited due to the lack of
physical certificates for their Book-Entry Securities. In addition,  issuance of
the  Book-Entry  Securities in  book-entry  form may reduce the liquidity of the
Book-Entry  Securities in the secondary market since certain potential investors
may be unwilling to purchase  Securities  for which they cannot obtain  physical
certificates.

                                       44



      DTC has advised the Depositor that, unless and until Definitive Securities
are issued,  DTC will take any action the holders of the  Book-Entry  Securities
are  permitted  to take under the Pooling and  Servicing  Agreement  only at the
direction of one or more DTC  Participants  to whose DTC accounts the Book-Entry
Securities are credited, to the extent that these actions are taken on behalf of
Financial  Intermediaries  whose  holdings  include the  Book-Entry  Securities.
Clearstream or the Euroclear  Operator,  as the case may be, will take any other
action permitted to be taken by a Securityholder 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  Depositary to effect these  actions on its behalf  through DTC.
DTC may take actions, at the direction of the related Participants, with respect
to some Book-Entry  Securities which conflict with actions taken with respect to
other Book-Entry Securities.

      Definitive   Securities  will  be  issued  to  beneficial  owners  of  the
Book-Entry  Securities,  or their nominees,  rather than to DTC, only if (a) DTC
advises the Trustee 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  Securities and the Depositor or the Trustee is unable
to locate a qualified  successor  or (b) in the case of  Securities  of a Series
that  receive  distributions  pursuant  to  request or random  lot,  if pro rata
distributions cannot be made through the facilities of DTC.

      Upon the occurrence of any event  described in the  immediately  preceding
paragraph,  the Trustee  will be required  to notify the  applicable  beneficial
owners  of the  occurrence  of the  event and the  availability  through  DTC of
Definitive  Securities.  Upon  surrender  by DTC of the  global  certificate  or
certificates   representing  the  Book-Entry  Securities  and  instructions  for
re-registration,  the Trustee will issue Definitive  Securities,  and thereafter
the  Trustee  will  recognize  the  holders of those  Definitive  Securities  as
Securityholders under the Pooling and Servicing Agreement.

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

      In the event of the  insolvency of DTC, a DTC  Participant  or an Indirect
DTC Participant in whose name Book-Entry Securities are registered,  the ability
of the Beneficial  Owners of the Book-Entry  Securities to obtain timely payment
and, if the limits of applicable  insurance coverage by the Securities  Investor
Protection Corporation are exceeded or if the coverage is otherwise unavailable,
ultimate  payment,  of amounts  distributable  with  respect  to the  Book-Entry
Securities may be impaired.

      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  seller's
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 issued in same-day funds.

      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
Book-Entry  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
Depositary,  as the case may be, to receive the  Book-Entry  Securities  against
payment. Payment will include interest accrued on the Book-Entry Securities from
and including the last coupon payment date to and

                                       45



excluding the  settlement  date, on the basis of either a 360-day year comprised
of 30-day months or the actual  number of days in the accrual  period and a year
assumed to consist of 360 days, as applicable.  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
Depositary of the DTC  Participant's  account against delivery of the Book-Entry
Securities.  After settlement has been completed, the Book-Entry 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 Book-Entry  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 Book-Entry 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 Book-Entry Securities would incur overdraft charges for
one day, assuming they cleared the overdraft when the Book-Entry Securities were
credited to their accounts. However, interest on the Book-Entry Securities would
accrue from the value date.  Therefore,  in many cases the investment  income on
the Book-Entry  Securities  earned during that one-day period may  substantially
reduce or offset the amount of the 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 Book-Entry Securities
to  the   respective   European   Depositary  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
Book-Entry  Securities are to be transferred by the respective  clearing system,
through the respective  Depositary,  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  Depositary,  as
appropriate,  to deliver  the  Book-Entry  Securities  to the DTC  Participant's
account against payment. Payment will include interest accrued on the Book-Entry
Securities  from and  including  the last coupon  payment to and  excluding  the
settlement date on the basis of either a 360-day year comprised of 30-day months
or the actual number of days in the accrual period and a year assumed to consist
of 360 days, as applicable.  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
Book-Entry   Securities  from  DTC  Participants  for  delivery  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:

                                       46



            (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 Book-Entry Securities in the U.S. from a DTC
      Participant  no later than one day prior to  settlement,  which would give
      the  Book-Entry  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 Book-Entry  Securities  that is not a U.S. Person within the meaning of
Section  7701(a)(30)  of the Code (a  "Non-U.S.  Holder")  holding a  Book-Entry
Security  through  Clearstream,   Euroclear  or  DTC  may  be  subject  to  U.S.
withholding  tax unless it provides  certain  documentation  to the  Trustee,  a
Paying Agent or any other entity required to withhold tax (any of the foregoing,
a "U.S.  Withholding  Agent")  establishing  an exemption  from  withholding.  A
Non-U.S. Holder may be subject to withholding unless each U.S. Withholding Agent
receives:

      (i)    from a Non-U.S. Holder that is classified as a corporation for
U.S.  federal income tax purposes or is an  individual,  and is eligible for the
benefits of the portfolio  interest  exemption or an exemption (or reduced rate)
based on a  treaty,  a duly  completed  and  executed  IRS Form  W-8BEN  (or any
successor form);

      (ii)   from a Non-U.S.  Holder that is eligible  for an  exemption  on the
basis that the holder's  income from the  Book-Entry  Securities is  effectively
connected to its U.S. trade or business,  a duly completed and executed IRS Form
W-8ECI (or any successor form);

      (iii)  from a Non-U.S. Holder that is classified as a partnership for U.S.
federal  income tax purposes,  a duly completed and executed IRS Form W-8IMY (or
any successor form) with all supporting  documentation (as specified in the U.S.
Treasury  regulations)  required to substantiate  exemptions from withholding on
behalf of its partners;  certain partnerships may enter into agreements with the
IRS providing for different  documentation  requirements  and it is  recommended
that those partnerships consult their tax advisors regarding these certification
rules;

      (iv)   from a Non-U.S.  Holder  that is an  intermediary  (i.e.,  a person
acting  as a  custodian,  a broker,  nominee  or  otherwise  as an agent for the
Beneficial Owner of Book-Entry Securities):

             (a) if the  intermediary is a "qualified  intermediary"  within the
      meaning of Section  1.1441-1(e)(5)(ii) of the U.S. Treasury regulations (a
      "Qualified  Intermediary"),  a duly completed and executed IRS Form W-8IMY
      (or any successor or substitute form):

                 (1)   stating  the  name,   permanent   residence  address  and
             employer  identification  number of the Qualified  Intermediary and
             the country under the laws of which the Qualified  Intermediary  is
             created, incorporated or governed,

                 (2)   certifying that the Qualified  Intermediary has provided,
             or will provide, a withholding  statement as required under Section
             1.1441-1(e)(5)(v) of the U.S. Treasury regulations,

                 (3)   certifying  that,  with respect to accounts it identifies
             on its  withholding  statement,  the qualified  intermediary is not
             acting  for  its  own   account   but  is  acting  as  a  qualified
             intermediary, and

                 (4)   providing  any  other  information,   certifications,  or
             statements  that  may  be  required  by  the  IRS  Form  W-8IMY  or
             accompanying instructions in addition to, or in lieu of, the

                                       47



             information    and    certifications     described    in    Section
             1.1441-1(e)(3)(ii)   or  1.1441-1(e)(5)(v)  of  the  U.S.  Treasury
             regulations; or

             (b) if the  intermediary  is not a Qualified  Intermediary,  a duly
      completed  and  executed IRS Form W-8IMY (or any  successor or  substitute
      form):

                 (1)   stating the name and permanent  residence  address of the
             non-Qualified  Intermediary and the country under the laws of which
             the   non-Qualified   Intermediary  is  created,   incorporated  or
             governed,

                 (2)   certifying  that the  non-Qualified  Intermediary  is not
             acting for its own account,

                 (3)   certifying  that  the   non-Qualified   Intermediary  has
             provided,   or  will  provide,  a  withholding  statement  that  is
             associated  with the  appropriate IRS Forms W-8 and W-9 required to
             substantiate   exemptions   from   withholding  on  behalf  of  the
             non-Qualified Intermediary's beneficial owners, and

                 (4)   providing  any  other   information,   certifications  or
             statements  that  may  be  required  by  the  IRS  Form  W-8IMY  or
             accompanying  instructions  in  addition  to,  or in lieu  of,  the
             information,  certifications,  and statements  described in Section
             1.1441-1(e)(3)(iii) or (iv) of the U.S. Treasury regulations; or

      (v)    from a Non-U.S.  Holder that is a trust,  depending  on whether the
trust is classified for U.S. federal income tax purposes as the beneficial owner
of  Book-Entry  Securities,  either an IRS Form W-8BEN or W-8IMY;  any  Non-U.S.
Holder that is a trust should  consult its tax  advisors to  determine  which of
these forms it should provide.

      All Non-U.S. Holders will be required to update the above-listed forms and
any supporting  documentation in accordance with the requirements under the U.S.
Treasury  regulations.  These  forms  generally  remain in  effect  for a period
starting  on the date the form is signed and ending on the last day of the third
succeeding calendar year, unless a change in circumstances makes any information
on the form  incorrect.  Under  certain  circumstances,  an IRS Form W-8BEN,  if
furnished  with a taxpayer  identification  number,  remains in effect until the
status of the beneficial owner changes,  or a change in circumstances  makes any
information on the form incorrect.

      In addition, all holders, including holders that are U.S. Persons, holding
Book-Entry  Securities through  Clearstream,  Euroclear or DTC may be subject to
backup withholding unless the holder:

            (a)   provides the appropriate IRS Form W-8 (or any successor or
      substitute form), duly completed and executed, if the holder is a Non-U.S.
      Holder;

            (b)   provides a duly  completed  and  executed IRS Form W-9, if the
      Holder is a U.S. Person; or

            (c)   can be treated as a "exempt  recipient"  within the meaning of
      Section  1.6049-4(c)(1)(ii)  of the U.S.  Treasury  regulations  (e.g.,  a
      corporation or a financial institution such as a bank).

      This summary does not deal with all of the aspects of U.S.  federal income
tax withholding or backup withholding that may be relevant to investors that are
Non-U.S.  Holders.  Those  holders are advised to consult their own tax advisors
for specific tax advice  concerning  their  holding and  disposing of Book-Entry
Securities.

Mandatory Auction of Certificates

      If  specified  in the  prospectus  supplement  for a  series,  one or more
Classes of  Securities  ("Auction  Securities")  may be  subject to a  mandatory
auction.  Prior to a Distribution  Date  specified in the applicable  prospectus
supplement  (the  "Auction  Distribution  Date"),  the Trustee or another  party
specified in the prospectus

                                       48



supplement,   in  its   capacity   as  auction   administrator   (the   "Auction
Administrator"),  will  solicit  bids for the  purchase of each Class of Auction
Securities then outstanding from third party investors.

      On  the  Auction   Distribution  Date,  the  Auction  Securities  will  be
transferred to third party investors, and upon this transfer the holders of each
class of Auction  Securities  will be  entitled  to receive an amount  (the "Par
Price") equal to the related  Security  Balance,  plus, if  applicable,  accrued
interest on that Class Balance  (following all  distributions and the allocation
of Realized Losses on the Auction Distribution Date).

      The Auction  Administrator  will enter into a swap  agreement  pursuant to
which the  counterparty  will agree to pay the excess,  if any, of the Par Price
over the amounts received for a Class of Auction  Securities in the auction.  If
all or a portion of a Class of Auction  Securities  is not sold in the  auction,
the counterparty will pay the Auction Administrator the Par Price (or portion of
the Par Price) of the unsold  Securities.  If the amount received in the auction
is greater  than the Par  Price,  that  excess  will be paid by the Trust to the
counterparty to the swap agreement and will not be available for distribution to
Securityholders.

      If the counterparty  defaults on its obligations under the swap agreement,
no  Securities of a Class of Auction  Securities  will be  transferred  to third
parties  unless  bids equal to or higher than the  applicable  Par Price (or pro
rata portion in the case of a bid for less than all of a Class) are received. In
addition,  if the counterparty  defaults and third party investors bid an amount
equal to or higher than the pro rata portion of the Par Price for some,  but not
all, of a Class of Auction Securities,  only a portion of the Securities of such
Class will be transferred to the successful bidders on the Auction  Distribution
Date.  If only a portion of a Class is  transferred,  each  holder of such Class
will  transfer  only a pro  rata  portion  of  its  Securities  on  the  Auction
Distribution Date.

      See  "Risk  Factors--Amounts  Received  from  the  Auction  and  the  Swap
Agreement  May Be  Insufficient  to Assure  Completion  of the  Auction" in this
prospectus.

                          DESCRIPTION OF THE AGREEMENTS

Agreements Applicable to a Series

      REMIC Securities, Grantor Trust Securities

      Securities  representing  interests in a Trust Fund, or a portion thereof,
that the Trustee will elect to have treated as REMIC Securities or Grantor Trust
Securities will be issued, and the related Trust Fund will be created,  pursuant
to a pooling and servicing agreement (a "Pooling and Servicing Agreement") among
the Depositor,  the Trustee and the Servicer,  Servicers or Master Servicer,  as
applicable.  The Assets of such Trust Fund will be transferred to the Trust Fund
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
such Trust Fund, each Servicer may perform its servicing functions pursuant to a
servicing agreement (each, an "Underlying Servicing Agreement").

      Securities That Are Partnership Interests for Tax Purposes and Notes

      Partnership  Securities  that are  partnership  interests for tax purposes
will be issued,  and the  related  Trust  Fund will be  created,  pursuant  to a
Pooling and Servicing Agreement.

      A Series of Notes  issued by a Trust  Fund will be issued  pursuant  to an
indenture  (the  "Indenture")  between the related  Trust Fund and the Indenture
Trustee  named in the  related  prospectus  supplement.  The Trust  Fund will be
established  pursuant  to a deposit  trust  agreement  (each,  a "Deposit  Trust
Agreement")  between  the  Depositor  and  an  owner  trustee  specified  in the
prospectus  supplement  relating  to such Series of Notes.  The Assets  securing
payment on the Notes will be serviced in accordance  with a servicing  agreement
(each,  an "Indenture  Servicing  Agreement")  between the related Trust Fund as
issuer of the Notes,  the Servicer and the  Indenture  Trustee.  The Pooling and
Servicing  Agreements,   the  Indenture  Servicing  Agreements,  the  Underlying
Servicing Agreements and the Indenture are referred to each as an "Agreement."

                                       49



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 and Underlying Servicing Agreement.  The
prospectus  supplement  for a Series of  Securities  will  describe the specific
provisions of the applicable  Agreement  relating to such Series. The provisions
of each  Agreement  will vary  depending upon the nature of the Securities to be
issued  thereunder and the nature of the related Trust Fund. As used herein with
respect to any Series,  the term  "Security"  refers to all of the Securities of
that  Series,  whether  or not  offered  hereby  and by the  related  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  servicers  (the  "Servicers"),   any  master  servicer  (the  "Master
Servicer") and the trustee (the "Trustee") or indenture  trustee (the "Indenture
Trustee"), as applicable, with respect to any Series of Securities will be named
in the related prospectus supplement.  In the event there are multiple Servicers
for  the  Assets  in a  Trust  Fund,  a  Master  Servicer  may  perform  certain
administration,  calculation and reporting  functions with respect to such Trust
Fund and  supervise  the related  Servicers  pursuant to a Pooling and Servicing
Agreement.  With respect to 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 related prospectus
supplement,  a securities administrator may be appointed pursuant to the Pooling
and Servicing Agreement for any Trust Fund to administer such Trust Fund.

      Assignment of Assets; Repurchases

      At the time of issuance of any Series of  Securities,  the Depositor  will
assign (or cause to be  assigned)  to the  designated  Trustee  the Assets to be
included in the related Trust Fund,  together with all principal and interest to
be received on or with respect to such 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 such assignment,  deliver
the  Securities to the Depositor in exchange for the Assets and the other assets
comprising  the Trust Fund for such Series.  Each Asset will be  identified in a
schedule appearing as an exhibit to the applicable Agreement. Such schedule will
include detailed information to the extent available and relevant (i) in respect
of each  Mortgage Loan  included in the related  Trust Fund,  including  without
limitation, the state and zip code of the related Mortgaged Property and type of
such property,  the Mortgage  Interest 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;  and (ii) in respect of each
Contract included in the related Trust Fund,  including  without  limitation the
outstanding principal amount and the Contract Rate.

      With respect to each Mortgage Loan,  the Depositor  generally will deliver
or cause to be delivered to the Trustee (or a custodian for the Trustee) certain
loan  documents,  which will in most cases  include the original  Mortgage  Note
endorsed,  without  recourse,  in blank  or to the  order  of the  Trustee,  the
original  Mortgage  (or a certified  copy  thereof)  with  evidence of recording
indicated thereon and an assignment of the Mortgage to the Trustee in recordable
form.  Notwithstanding  the foregoing,  a Trust Fund may include  Mortgage Loans
where  the  original  Mortgage  Note  is not  delivered  to the  Trustee  if the
Depositor or Asset Seller delivers to the Trustee or a custodian for the Trustee
a copy or a duplicate original of the Mortgage Note,  together with an affidavit
certifying that the original thereof has been lost or destroyed. With respect to
such 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  related  prospectus  supplement  will be required to agree to
repurchase,  or substitute  for, each such Mortgage Loan 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 applicable
Agreement will generally require the Depositor or another party specified in the
related prospectus supplement to promptly cause each such assignment of Mortgage
to be recorded  in the  appropriate  public  office for real  property  records,
unless (i) with  respect to a  particular  state,  the Trustee  has  received an
opinion of counsel  acceptable to it that such recording is not required to make
the  assignment  effective  against  the parties to the  Mortgage or  subsequent
purchasers or encumbrancers  of the Mortgaged  Property or (ii) recordation in a
state is not  required  by the  Rating  Agencies  rating  the Series in order to
obtain the initial ratings on the Securities described in the related prospectus
supplement.

                                       50



      Notwithstanding the preceding paragraph, with respect to any Mortgage Loan
which has been recorded in the name of Mortgage Electronic Registration Systems,
Inc.  ("MERS") or its designee,  no mortgage  assignment in favor of the Trustee
will be required to be prepared or delivered.  Instead,  the Master Servicer and
the applicable Servicer will be required to take all actions as are necessary to
cause the applicable Trust Fund to be shown as the owner of the related Mortgage
Loan on the records of MERS for purposes of the system of recording transfers of
beneficial ownership of mortgages maintained by MERS.

      The Trustee (or a  custodian)  will review such  Mortgage  Loan  documents
within a period of days  specified in the related  prospectus  supplement  after
receipt  thereof,  and the Trustee (or a custodian)  will hold such documents in
trust for the benefit of the  Securityholders.  If any such document is found to
be missing or defective in any material respect, the Trustee (or such custodian)
shall immediately notify the Asset Seller,  the Servicer,  the Depositor and any
other entity specified in the related prospectus supplement. If the Asset Seller
or other entity specified in the related  prospectus  supplement cannot cure the
omission  or defect  within a  specified  number of days  after  receipt of such
notice,  then  the  Asset  Seller  or  other  entity  specified  in the  related
prospectus  supplement will be obligated,  within a specified  number of days of
receipt of such notice, to repurchase the related Mortgage Loan from the Trustee
at a price equal to the sum of the unpaid principal balance thereof, plus unpaid
accrued  interest at the interest  rate for such Asset from the date as to which
interest  was last  paid to the due date in the  Collection  Period in which the
relevant  purchase is to occur,  plus any unpaid servicing fees and unreimbursed
advances  that are payable to the  Servicer or such other price as  specified in
the related prospectus  supplement (the "Purchase Price") or substitute for such
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
such  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.

      Notwithstanding  the preceding two paragraphs,  the documents with respect
to Home Equity Loans, Home Improvement  Contracts and Unsecured Home Improvement
Loans will be  delivered  to the  Trustee  (or a  custodian)  only to the extent
specified in the related prospectus supplement. Generally such 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 related prospectus supplement.

      With respect to 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 and the security interest in
the  Manufactured  Home securing each  Contract.  In order 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 authorized 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 Company to the Trust Fund only to the extent  specified  in
the related prospectus supplement.  Therefore, if, through negligence,  fraud or
otherwise,  a subsequent  purchaser were able to take physical possession of the
Contracts without notice of such assignment,  the interest of the Trustee in the
Contracts could be defeated. See "Certain Legal Aspects of the Contracts."

      While the  Contract  documents  will not be reviewed by the Trustee or the
Servicer,  if the Servicer  finds that any such 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 related
prospectus supplement.  If the Asset Seller or such other entity cannot cure the
omission  or defect  within a  specified  number of days  after  receipt of such
notice,  then the Asset Seller or such other entity will be obligated,  within a
specified  number of days of receipt of such notice,  to repurchase  the related
Contract from the Trustee at the Purchase Price or substitute for such Contract.
There can be no assurance that an Asset Seller or such other entity will fulfill
this  repurchase or  substitution  obligation,  and neither the Servicer nor the
Depositor will be obligated to repurchase or substitute for such Contract if the
Asset Seller or such 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  related  prospectus
supplement,  in  lieu  of  curing  any  omission  or  defect  in  the  Asset  or
repurchasing or substituting for such Asset, the Asset Seller may agree to cover
any losses suffered by the Trust Fund as a result of such breach or defect.

                                       51



      Representations and Warranties; Repurchases

      To the extent  provided in the  related  prospectus  supplement  the Asset
Seller,  the Sponsor or the  Depositor or any  combination  thereof  will,  with
respect to each Asset, make or assign certain representations and warranties, as
of a specified date (the person making such representations and warranties,  the
"Warranting Party") covering, by way of example, the following types of matters:
(i) the accuracy of the  information set forth for such Asset on the schedule of
Assets appearing as an exhibit to the applicable Agreement;  (ii) in the case of
a Mortgage Loan, the existence of title insurance  insuring the lien priority of
the Mortgage Loan or an opinion of counsel of the type  customarily  rendered in
the applicable jurisdiction in lieu of a title insurance policy and, in the case
of a Contract,  that the Contract creates a valid first security  interest in or
lien on the related  Manufactured  Home;  (iii) the authority of the  Warranting
Party to sell the Asset;  (iv) the payment status of the Asset;  (v) 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 (vi) the existence of hazard
insurance coverage on the Mortgaged Property or Manufactured Home.

      Any Warranting  Party shall be an Asset Seller or an affiliate  thereof or
such other person  acceptable  to the  Depositor  and shall be identified in the
related prospectus supplement.

      Representations  and warranties  made in respect of an Asset may have been
made as of a date prior to the applicable  Cut-off Date. A substantial period of
time may have elapsed between such date and the date of initial  issuance of the
related Series of Securities  evidencing an interest in such Asset. In the event
of a breach of any such representation or warranty, the Warranting Party will be
obligated  to reimburse  the Trust Fund for losses  caused by any such breach or
either cure such 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 such a  representation  and warranty only if the relevant event
that causes such breach occurs prior to such date. Although the Warranting Party
would have no such  obligations  if the  relevant  event that causes such breach
occurs  after such date,  the Sponsor  specified  in the  applicable  prospectus
supplement will generally be required by the applicable  Rating Agencies to make
representations and warranties that address this gap period.

      Each Agreement will provide that the Servicer and/or Trustee or such other
entity  identified  in the  related  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 such  Asset or the  interests  therein  of the
Securityholders.  If such  Warranting  Party  cannot cure such  breach  within a
specified  period  following  the date on which such party was  notified of such
breach,  then such  Warranting  Party will be obligated to repurchase such Asset
from the Trustee within a specified period from the date on which the Warranting
Party was  notified  of such  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 such Series of
Securities,  to  cause  the  removal  of such  Asset  from  the  Trust  Fund and
substitute in its place one or more other Assets,  as applicable,  in accordance
with  the  standards  described  in  the  related  prospectus  supplement.  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.

      The Sponsor identified in the applicable prospectus supplement, if not the
Warranting Party, in addition to making representations and warranties regarding
the Assets  covering  any gap  between  the date the  Warranting  Party made its
representations  and warranties and the Closing Date as described above, will be
obligated to repurchase  such Asset from the Trustee  within a specified  period
from the date on which it is  notified  of a breach of its  representations  and
warranties  if it cannot cure such breach but only to the extent the  Warranting
Party is not also obligated to repurchase  such Asset from the Trustee.  Neither
the  Depositor  nor the  Servicer  (except to the extent  the  Depositor  or the
Servicer is the  Warranting  Party) 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 Warranting  Parties will carry out such  obligations
with respect to the Assets.

      A Servicer will make certain  representations and warranties regarding its
authority to enter into, and its ability to perform its obligations  under,  the
applicable Agreement.  A breach of any such representation of the

                                       52



Servicer  which   materially   and  adversely   affects  the  interests  of  the
Securityholders and which continues  unremedied for the number of days specified
in the applicable Agreement after the giving of written notice of such breach to
the Servicer by the Trustee or the Depositor,  or to the Servicer, the Depositor
and the Trustee by the holders of Securities evidencing not less than 25% of the
Voting  Rights or such other  percentage  specified  in the  related  prospectus
supplement,  will  constitute  an Event of  Default  under such  Agreement.  See
"--Events of Default under the  Agreements"  and "--Rights Upon Event of Default
under the Agreements."

      Collection Account and Related Accounts

      General.  The Servicer will, as to each Trust Fund, 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  meet  the  requirements  set  forth  in the  applicable
prospectus  supplement.  A Collection  Account may be  maintained as an interest
bearing or a non-interest  bearing account and, if interest  bearing,  the funds
held  therein may be  invested  pending  each  succeeding  Distribution  Date in
certain investments  acceptable to the applicable Rating Agencies.  Any interest
or other income earned on funds in the Collection Account will generally 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 such 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.  The  Trustee  or a  securities
administrator, if specified in the applicable prospectus supplement, will, as to
each  Trust  Fund,  establish  and  maintain  or  cause  to be  established  and
maintained a separate account into which it will deposit amounts remitted by the
Servicer  or  Master   Servicer  for   distribution  to   Securityholders   (the
"Distribution  Account"),  which  must  meet the  requirements  set forth in the
applicable prospectus supplement.

      Deposits.  A  Servicer  will  deposit  or  cause  to be  deposited  in the
Collection  Account for one or more Trust Funds on a daily basis,  or such other
period  provided  in  the  applicable  Agreement,  the  following  payments  and
collections received, or advances made, by the Servicer or the Trustee or on its
behalf  subsequent to the Cut-off Date (other than payments due on or before the
Cut-off Date, and exclusive of any amounts representing a Retained Interest):

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

      (ii)   all  payments on account of interest on the Assets,  including  any
default interest collected,  in each case net of any portion thereof retained by
a Servicer as its servicing compensation and net of any Retained Interest;

      (iii)  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;

      (iv)   any amounts paid under any  instrument  or drawn from any fund that
constitutes  credit  support for the related  Series of  Securities as described
under "Description of Credit Support";

      (v)    any  advances  made  as  described   under   "Description   of  the
Securities--Advances in Respect of Delinquencies";

      (vi)   any amounts paid under any Cash Flow Agreement,  as described under
"Cash Flow Agreements";

      (vii)  all  proceeds of any Asset or,  with  respect to a  Mortgage  Loan,
property  acquired in respect thereof  purchased by the Depositor,  the Sponsor,
any Asset Seller or any other specified person as described under  "--Assignment
of Assets; Repurchases" and "--Representations and Warranties; Repurchases," all
proceeds  of  any  defaulted   Mortgage  Loan   purchased  as  described   under
"--Realization  Upon Defaulted  Assets," and all proceeds of any Asset purchased
as described under "Description of the Securities--Termination";

                                       53



      (viii) any amounts paid by a Servicer to cover certain interest shortfalls
arising out of the  prepayment  of Assets in the Trust Fund as  described  under
"Description of the  Agreements--Retained  Interest;  Servicing Compensation and
Payment of Expenses";

      (ix)   to the  extent  that any such item does not  constitute  additional
servicing compensation to a Servicer, any payments on account of modification or
assumption fees, late payment charges or Prepayment Charges on the Assets;

      (x)    all payments  required to be deposited  in the  Collection  Account
with respect to any deductible  clause in any blanket insurance policy described
under "--Hazard Insurance Policies";

      (xi)   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

      (xii)  any  other  amounts  required  to be  deposited  in the  Collection
Account as provided in the  applicable  Agreement  and  described in the related
prospectus supplement.

      Withdrawals.  A Servicer may, from time to time, make withdrawals from the
Collection Account for each Trust Fund for any of the following purposes:

      (i)    to remit to the Trustee or securities  administrator for deposit in
the Distribution Account;

      (ii)   to  reimburse  a Servicer  for  unreimbursed  amounts  advanced  as
described  under  "Description  of  the   Securities--Advances   in  Respect  of
Delinquencies," such reimbursement to be made out of amounts received which 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  with  respect to which the  advances  were made or out of amounts  drawn
under any form of credit support with respect to such Assets;

      (iii)  to  reimburse  a Servicer  for  unpaid  servicing  fees  earned and
certain  unreimbursed  servicing  advances and expenses incurred with respect to
Assets and properties acquired in respect thereof, such reimbursement 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,  with respect to which such fees were earned or such
expenses were incurred or out of amounts drawn under any form of credit  support
with respect to such Assets and properties;

      (iv)   to reimburse a Servicer  for any advances  described in clause (ii)
above and any servicing  expenses  described in clause (iii) above which, in the
Servicer's  good  faith  judgment,  will not be  recoverable  from  the  amounts
described in clauses (ii) and (iii), respectively, such reimbursement to be made
from amounts collected on other Assets;

      (v)    if  and  to  the  extent   described  in  the  related   prospectus
supplement,  to pay a Servicer  interest  accrued on the  advances  described in
clause (ii) above and the  servicing  expenses  described  in clause (iii) above
while such advances and servicing expenses remain outstanding and unreimbursed;

      (vi)   to reimburse a Servicer, the Depositor,  or any of their respective
directors,  officers,  employees  and  agents,  as the case may be, for  certain
expenses, costs and liabilities incurred thereby, as and to the extent described
under "--Certain  Matters Regarding  Servicers and the Master Servicer" and "The
Depositor";

      (vii)  if  and  to  the  extent   described  in  the  related   prospectus
supplement, to pay the Trustee's fees;

      (viii) to  reimburse  the  Trustee  or  any of  its  directors,  officers,
employees  and  agents,  as the case may be,  for  certain  expenses,  costs and
liabilities  incurred  thereby,  as and to the extent described under "--Certain
Matters Regarding the Trustee";

                                       54



      (ix)   to pay a Servicer, as additional servicing  compensation,  interest
and  investment  income  earned in  respect of  amounts  held in the  Collection
Account;

      (x)    to pay the person  entitled  thereto any amounts  deposited  in the
Collection  Account  that  were  identified  and  applied  by  the  Servicer  as
recoveries of Retained Interest;

      (xi)   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,
such payments to be made out of income received on such property;

      (xii)  if one or more  elections have been made to treat the Trust Fund or
designated portions thereof as a REMIC, to pay any federal, state or local taxes
imposed on the Trust Fund or its  assets or  transactions,  as and to the extent
described  under  "Federal  Income Tax  Consequences--REMICs--Taxes  That May Be
Imposed  on  the  REMIC  Pool"  or  in  the  applicable  prospectus  supplement,
respectively;

      (xiii) to pay for  the  cost  of  various  opinions  of  counsel  obtained
pursuant to the applicable Agreement for the benefit of Securityholders;

      (xiv)  to pay the person  entitled  thereto any amounts  deposited  in the
Collection  Account in error,  including amounts received on any Asset after its
removal  from the Trust Fund  whether by reason of purchase or  substitution  as
contemplated by "--Assignment of Assets;  Repurchase" and "--Representations and
Warranties; Repurchases" or otherwise;

      (xv)   to  make  any  other   withdrawals   permitted  by  the  applicable
Agreement; and

      (xvi)  to clear and terminate the Collection Account at the termination of
the Trust Fund.

      Other Collection Accounts.  Notwithstanding the foregoing, if so specified
in the related prospectus supplement, the applicable Agreement for any Series of
Securities  may  provide for the  establishment  and  maintenance  of a separate
collection  account  into which the  Servicer  will deposit on a daily basis the
amounts described under "--Deposits" above for one or more Series of Securities.
Any  amounts  on  deposit  in any  such  collection  account  will be  withdrawn
therefrom  and  deposited  into the  appropriate  Collection  Account  by a time
specified in the related prospectus  supplement.  To the extent specified in the
related  prospectus  supplement,  any amounts which could be withdrawn  from the
Collection  Account  as  described  under  "--Withdrawals"  above,  may  also be
withdrawn from any such collection account.  The prospectus  supplement will set
forth any restrictions  with respect to any such collection  account,  including
investment   restrictions  and  any  restrictions   with  respect  to  financial
institutions with which any such collection account may be maintained.

      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  such  collection  procedures  as it would
follow with respect to assets that are comparable to the Assets and held for its
own account,  provided such  procedures are consistent with (i) the terms of the
applicable  Agreement and any related hazard  insurance  policy or instrument of
credit support,  if any,  included in the related Trust Fund described herein or
under "Description of Credit Support," (ii) applicable law and (iii) the general
servicing standard specified in the related prospectus supplement or, if no such
standard is so specified,  its normal  servicing  practices (in either case, the
"Servicing Standard").  In connection therewith,  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,  subject to the terms and  conditions  of
the applicable agreement.

      Each Servicer will also be required to perform other  customary  functions
of a servicer of  comparable  assets,  including  maintaining  hazard  insurance
policies as  described  herein and in any  related  prospectus  supplement,  and
filing and settling claims  thereunder;  maintaining,  to the extent required by
the applicable Agreement, escrow or impoundment accounts of obligors for payment
of taxes,  insurance and other items required to be paid by any obligor 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

                                       55



delinquencies;   supervising  foreclosures  or  repossessions;   inspecting  and
managing Mortgaged Properties or Manufactured Homes under certain circumstances;
and maintaining  accounting records relating to the Assets. The Servicer or such
other entity specified in the related 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 is not materially  adverse to  Securityholders  and will not
change the Mortgage Interest Rate or Contract Rate, defer or forgive the payment
thereof of any principal or interest payments,  reduce the outstanding principal
amount  (except for actual  payments of principal) or extend the final  maturity
date with respect to such Asset. If a REMIC election has been made for the Trust
Fund, such modification, waiver or amendment may not affect adversely the status
of any REMIC  constituting  part of the Trust  Fund as a REMIC or cause any such
REMIC to be subject to a tax on  "prohibited  transactions"  or  "contributions"
pursuant  to  the  REMIC  Provisions.   The  Servicer  also  may  agree  to  any
modification,  waiver or  amendment  that  would  reduce the  Principal  Balance
thereof,  extend the term of the Asset or reduce the Mortgage  Interest  Rate or
Contract rate by up to 50 basis points if, in its judgment,  a material  default
on the Asset has occurred or a payment  default is reasonably  foreseeable.  The
Servicer is  required  to notify the  Trustee in the event of any  modification,
waiver or amendment of any Asset.

      Notwithstanding the foregoing to the contrary, in the event of a voluntary
principal  prepayment  in full of a Mortgage  Loan, a Servicer may not waive any
Prepayment  Charge or  portion  thereof  required  by the  terms of the  related
Mortgage Note unless (i)(a) the Servicer determines that such waiver is standard
and customary in servicing  similar mortgage loans, (b) such waiver relates to a
default or a reasonably  foreseeable  default and (c) would,  in the  reasonable
judgment of the Servicer,  maximize  recovery of  Liquidation  Proceeds for such
Mortgage Loan, taking into account the value of such Prepayment  Charge, or (ii)
the enforceability thereof is limited (1) by bankruptcy, insolvency, moratorium,
receivership,  or other similar law relating to creditors'  rights  generally or
(2) due to acceleration  in connection  with a foreclosure or other  involuntary
payment.  If the  Servicer  waives or does not  collect  all or a  portion  of a
Prepayment  Charge relating to a voluntary  Principal  Prepayment in full due to
any action or  omission  of the  Servicer,  other than as  provided  above,  the
Servicer  generally will, on the date on which the principal  prepayment in full
is remitted to the Trustee,  deliver to the Trustee the amount of the Prepayment
Charge from its own funds for  distribution  in accordance with the terms of the
applicable Agreement.

      In the case of Multifamily  Mortgage Loans, a mortgagor'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 mortgagor  under a
Multifamily 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  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 the related Mortgaged Property,
initiate  corrective action in cooperation with the mortgagor if cure is likely,
inspect  the related  Multifamily  Property  and take such other  actions as are
consistent  with the  applicable  Agreement.  A  significant  period of time may
elapse before the Servicer is able to assess the success of any such  corrective
action  or the need  for  additional  initiatives.  The time  within  which  the
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  Mortgage Loan, the  Multifamily  Property,  the
mortgagor,  the  presence  of an  acceptable  party to  assume  the  Multifamily
Mortgage Loan and the laws of the jurisdiction in which the Multifamily Property
is located.

      Realization Upon Defaulted Assets

      Generally,  the  Servicer is  required  to monitor any Assets  which is in
default, initiate corrective action in cooperation with the mortgagor or obligor
if cure is  likely,  inspect  the  Asset  and take  such  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 such  corrective  action or
the need for additional initiatives.

                                       56



      Any  Agreement  relating to a Trust Fund that includes  Mortgage  Loans or
Contracts  may grant to the  Servicer  and/or  the  holder or holders of certain
Classes of  Securities a right of first  refusal to purchase from the Trust Fund
at a predetermined purchase price any such Mortgage Loan or Contract as to which
a specified  number of scheduled  payments  thereunder are delinquent.  Any such
right  granted to the holder of an Offered  Security  will be  described  in the
related  prospectus  supplement.  The related  prospectus  supplement  will also
describe  any such right  granted to any  person if the  predetermined  purchase
price is less than the Purchase Price  described  under  "--Representations  and
Warranties; Repurchases."

      If so specified  in the related  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 thereto,  if and when the Servicer  determines,  consistent
with the Servicing  Standard,  that such a sale would produce a greater recovery
on  a  present  value  basis  than  would   liquidation   through   foreclosure,
repossession or similar proceedings.  The applicable Agreement will provide that
any such 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 such defaulted  Mortgage Loan or Contract.  In
the absence of any bid determined in accordance with the applicable Agreement to
be fair, the Servicer shall proceed with respect to such defaulted Mortgage Loan
or  Contract  as  described  below.  Any bid in an amount at least  equal to the
Purchase Price described 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 such action is
consistent  with the  Servicing  Standard and a default on such Mortgage Loan or
Contract has occurred or, in the Servicer's judgment, is imminent.

      If title to any Mortgaged Property is acquired by a Trust Fund as to which
a REMIC election has been made, the Servicer,  on behalf of the Trust Fund, will
be required to sell the  Mortgaged  Property by the close of the third  calendar
year after the year of acquisition, unless (i) the Internal Revenue Service (the
"IRS")  grants an  extension  of time to sell such  property or (ii) the Trustee
receives an opinion of independent counsel to the effect that the holding of the
property by the Trust Fund  subsequent  to the close of the third  calendar year
after the year of the  acquisition  of the  property  by the Trust Fund will not
result in the  imposition  of a tax on the Trust Fund or cause the Trust Fund to
fail to qualify as a REMIC  under the Code at any time that any  Securities  are
outstanding.  Subject to the  foregoing,  the  Servicer  will be required to (i)
solicit bids for any Mortgaged  Property so acquired in such a manner as will be
reasonably  likely to realize a fair price for such property and (ii) 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  applicable  Agreement  and  the  REMIC
Provisions  of the Code (if a REMIC  election  has been made with respect to the
related Trust Fund) on the ownership  and  management of any Mortgaged  Property
acquired  on behalf of the Trust  Fund may result in the  recovery  of an amount
less than the amount that would  otherwise  be  recovered.  See  "Certain  Legal
Aspects of Mortgage Loans--Foreclosure."

      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  such  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
thereon at the applicable  interest rate, plus the aggregate  amount of expenses
incurred  by the  Servicer in  connection  with such  proceedings  and which are
reimbursable under the applicable Agreement,  the Trust Fund will realize a loss
in the amount of such  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,  prior to the  distribution of such
Liquidation  Proceeds  to  Securityholders,   amounts  representing  its  normal
servicing  compensation  on the Security,  unreimbursed  servicing  expenses and
advances  incurred  with respect to the Asset and any  unreimbursed  advances of
delinquent payments made with respect to the Asset.

      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   (i)  that  such   restoration   will   increase   the  proceeds  to

                                       57



Securityholders on liquidation of the Asset after  reimbursement of the Servicer
for its  expenses and (ii) that such  expenses  will be  recoverable  by it from
related Insurance Proceeds or Liquidation Proceeds.

      As servicer of the Assets,  a Servicer,  on behalf of itself,  the Trustee
and  the  Securityholders,  will  present  claims  to  the  obligor  under  each
instrument  of  credit  support,  and will  take  such  reasonable  steps as are
necessary to receive  payment or to permit  recovery  thereunder with respect to
defaulted Assets.

      If a Servicer or its designee  recovers  payments  under any instrument of
credit  support  with respect to any  defaulted  Assets,  the  Servicer  will be
entitled to withdraw or cause to be withdrawn from the Collection Account out of
such  proceeds,  prior  to  distribution  thereof  to  Securityholders,  amounts
representing  its normal  servicing  compensation  on such  Asset,  unreimbursed
servicing  expenses  incurred  with  respect  to 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 a Trust Fund comprised of
Mortgage Loans will require the Servicer to cause the mortgagor on each Mortgage
Loan to maintain a hazard  insurance  policy  providing  for such coverage as is
required  under the  related  Mortgage  or, if any  Mortgage  permits the holder
thereof to dictate to the mortgagor  the insurance  coverage to be maintained on
the related  Mortgaged  Property,  then such coverage as is consistent  with the
Servicing  Standard.  Such coverage will be in general in an amount equal to the
lesser of the  principal  balance owing on such 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 such other  amount  specified  in the  related
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 mortgagors.  All amounts collected by
the  Servicer  under any such  policy  (except  for amounts to be applied to the
restoration or repair of the Mortgaged  Property or released to the mortgagor 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.  The applicable  Agreement may provide that the Servicer
may satisfy its  obligation  to cause each  mortgagor to maintain  such a hazard
insurance policy by the Servicer's maintaining a blanket policy insuring against
hazard  losses  on the  Mortgage  Loans.  If  such  blanket  policy  contains  a
deductible  clause,  the Servicer will be required to deposit in the  Collection
Account all sums that would have been deposited therein but for such clause.

      In general,  the standard form hazard  insurance covers physical damage to
or  destruction  of  the  improvements  of  the  property  by  fire,  lightning,
explosion,  smoke,  windstorm and hail, 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  thereof  are  dictated  by
respective  state  laws,  and most  such  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, riot, strike and civil
commotion, and certain other kinds of uninsured risks.

      Each  Agreement for a Trust Fund  comprised of Mortgage Loans will require
the Servicer to cause the  mortgagor on each  Mortgage Loan to maintain all such
other insurance  coverage with respect to 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 such  insurance
policy will be  reimbursable  to it as a servicing  advance as  described  above
under "--Collection Account and Related Accounts."

      Under  the terms of the  Mortgage  Loans,  mortgagors  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

                                       58



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 such claims is dependent upon the extent to which  information in this
regard is furnished to the Servicer by mortgagors.

      Contracts

      Generally,  the  terms  of  the  applicable  Agreement  for a  Trust  Fund
comprised of Contracts will require the Servicer to cause to be maintained  with
respect to each Contract one or more hazard insurance policies which 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 such policies in the state in which the Manufactured Home is
located,  and in an amount which is not less than the maximum insurable value of
such  Manufactured  Home or the  principal  balance  due from the obligor on the
related  Contract,  whichever  is less;  provided,  however,  that the amount of
coverage  provided by each such hazard  insurance  policy shall 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
shall cause such flood  insurance to be  maintained,  which coverage shall be at
least equal to the minimum  amount  specified in the preceding  sentence or such
lesser  amount as may be available  under the federal flood  insurance  program.
Each hazard  insurance  policy  caused to be  maintained  by the Servicer  shall
contain a standard loss payee clause in favor of the Servicer and its successors
and  assigns.  If any  obligor is in default in the  payment of  premiums on its
hazard insurance policy or policies, the Servicer shall pay such premiums out of
its own funds,  and may add separately such premium to the obligor's  obligation
as  provided  by the  Contract,  but may not add such  premium to the  remaining
principal balance of the Contract.

      The Servicer may maintain,  in lieu of causing individual hazard insurance
policies to be  maintained  with respect to each  Manufactured  Home,  and shall
maintain,  to the extent that the related  Contract does not require the obligor
to maintain a hazard insurance  policy with respect to the related  Manufactured
Home, one or more blanket  insurance  policies  covering losses on the obligor's
interest  in the  Contracts  resulting  from the  absence  or  insufficiency  of
individual  hazard  insurance  policies.  The Servicer shall pay the premium for
such blanket policy on the basis described  therein and shall pay any deductible
amount with respect to claims under such policy relating to the Contracts.

      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 thereof insuring against loss occasioned by
fraud,  theft or other  intentional  misconduct of the  officers,  employees and
agents of the  Servicer.  The  applicable  Agreement  may 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 certain  criteria set forth in
such Agreement are met.

      Due-on-Sale Provisions

      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  provision  which  would  adversely  affect  or
jeopardize coverage under any applicable  insurance policy. 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 such clauses. The Servicer will generally permit such
transfer so long as the  transferee  satisfies the  Servicer's  then  applicable
underwriting  standards.  The  purpose  of such  transfers  is  often to avoid a
default  by  the  transferring  obligor.  See  "Certain  Legal  Aspects  of  the
Contracts--Transfers  of Manufactured  Homes;  Enforceability  of  "Due-on-Sale"
Clauses."

                                       59



      Retained Interest; Servicing Compensation and Payment of Expenses

      The prospectus  supplement for a Series of Securities will specify whether
there will be any Retained Interest in the Assets, and, if so, the initial owner
thereof.  If so, the Retained  Interest will be  established  on a  loan-by-loan
basis  and will be  specified  on an  exhibit  to the  applicable  Agreement.  A
"Retained  Interest" in an Asset represents a specified  portion of the interest
payable thereon.  The Retained Interest will be deducted from mortgagor payments
as received and will not be part of the related Trust Fund.

      The Servicer's primary servicing  compensation with respect to a Series of
Securities  will  come  from the  periodic  payment  to it of a  portion  of the
interest  payment on each Asset or such other  amount  specified  in the related
prospectus  supplement.  Since any Retained  Interest  and a Servicer's  primary
compensation  are  percentages  of the  principal  balance of each  Asset,  such
amounts will decrease in accordance  with the  amortization  of the Assets.  The
Servicing Fee or range of Servicing  Fees relating to the Assets  underlying the
Securities of a Series will be specified in an expense  table in the  applicable
prospectus  supplement.  The prospectus  supplement  with respect to a Series of
Securities  evidencing interests in a Trust Fund 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  Charges  collected from  mortgagors and any interest or other income
which may be earned  on funds  held in the  Collection  Account  or any  account
established by a Servicer pursuant to the applicable Agreement.

      The  Servicer  may,  to the  extent  provided  in the  related  prospectus
supplement,  pay from its servicing  compensation  certain expenses  incurred in
connection  with its  servicing and managing of the Assets,  including,  without
limitation, 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
related  prospectus  supplement.   Certain  other  expenses,  including  certain
expenses  relating to defaults and liquidations on the Assets and, to the extent
so provided in the related prospectus  supplement,  interest thereon at the rate
specified therein may be borne by the Trust Fund.

      If and to the extent provided in the related  prospectus  supplement,  the
Servicer  may be  required  to apply a  portion  of the  servicing  compensation
otherwise  payable to it in respect of any Collection Period to certain interest
shortfalls  resulting from the voluntary prepayment of any Assets in the related
Trust Fund during such period prior to their respective due dates therein.

      Evidence as to Compliance

      Each Servicer and Master Servicer will deliver  annually to the Trustee or
Master  Servicer,  as  applicable,  on or  before  the  date  specified  in  the
applicable Agreement,  an officer's certificate stating that (i) a review of the
Servicer's or Master Servicer's  activities  during the preceding  calendar year
and of  performance  under the  applicable  Agreement  has been  made  under the
supervision  of the officer,  and (ii) to the best of the  officer's  knowledge,
based on the review,  the  Servicer or Master  Servicer  has  fulfilled  all its
obligations under the applicable Agreement throughout the year, or, if there has
been a default in the  fulfillment  of any  obligation,  specifying  the default
known to the officer and the nature and status of the default.

      In  addition,   each  party  that   participates   in  the  servicing  and
administration  of more than 5% of the Assets  comprising  a Trust will  deliver
annually  to the  Depositor  and  the  Trustee,  a  report  (an  "Assessment  of
Compliance") that assesses  compliance by that party with the servicing criteria
set forth in Item 1122(d) of  Regulation  AB (17 CFR 229.1122) and that contains
the following:

      o     a statement of the party's  responsibility for assessing  compliance
            with the servicing criteria applicable to it;

      o     a  statement  that the party used the  criteria  in Item  1122(d) of
            Regulation AB to assess  compliance  with the  applicable  servicing
            criteria;

                                       60



      o     the party's  assessment of compliance with the applicable  servicing
            criteria  during  and as of the  end of  the  prior  calendar  year,
            setting forth any material  instance of noncompliance  identified by
            the party; and

      o     a statement that a registered  public  accounting firm has issued an
            Attestation  Report on the party's Assessment of Compliance with the
            applicable  servicing criteria during and as of the end of the prior
            calendar year.

      Each party which is required to deliver an Assessment  of Compliance  will
also be required to simultaneously deliver a report (an "Attestation Report") of
a registered public  accounting firm,  prepared in accordance with the standards
for attestation  engagements  issued or adopted by the Public Company Accounting
Oversight Board, that expresses an opinion,  or states that an opinion cannot be
expressed,  concerning the party's  assessment of compliance with the applicable
servicing criteria.

      Certain Matters Regarding Servicers and the Master Servicer

      The Servicers and Master  Servicer  under each  Agreement will be named in
the related  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. Reference herein
to the Servicer shall be deemed to be to the Master Servicer, if applicable.

      The  applicable  Agreement  will provide that the Servicer may resign from
its  obligations and duties  thereunder  only (i) upon a determination  that its
duties under such 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  such a
conflict  being of a type and nature  carried on by the  Servicer at the date of
such Agreement or (ii) upon  satisfaction of the following  conditions:  (a) the
Servicer  has  proposed a successor  servicer to the Trustee in writing and such
proposed  successor  servicer is reasonably  acceptable to the Trustee;  and (b)
each Rating  Agency shall have  delivered a letter to the Trustee,  prior to the
appointment of the successor servicer,  stating that the proposed appointment of
such  successor  servicer  as  Servicer  will not result in a  reduction  of the
then-current  ratings  of  the  Securities.  No  such  resignation  will  become
effective  until the Trustee or a successor  servicer has assumed the Servicer's
obligations and duties under the applicable Agreement.

      Each  Agreement  will  further  provide  that neither any Servicer nor any
director,  officer, employee, or agent of a Servicer will be under any liability
to the  related  Trust  Fund or  Securityholders  for any action  taken,  or for
refraining  from  the  taking  of any  action,  in good  faith  pursuant  to the
applicable  Agreement;  provided,  however, that neither of any Servicer nor any
such person will be protected against any breach of a  representation,  warranty
or  covenant  made in such  Agreement,  or against  any  liability  specifically
imposed  thereby,  or against any liability  which would otherwise be imposed by
reason of willful  misfeasance,  bad faith or negligence in the  performance  of
obligations  or  duties  thereunder  or  by  reason  of  reckless  disregard  of
obligations and duties thereunder. In addition, each Agreement will provide that
no Servicer will be under any  obligation to appear in,  prosecute or defend any
legal  action  which  is  not  incidental  to  its  responsibilities  under  the
applicable  Agreement  and which in its opinion may involve it in any expense or
liability.  Any such Servicer may, however, in its discretion undertake any such
action which it may deem  necessary or desirable  with respect to the applicable
Agreement and the rights and duties of the parties  thereto and the interests of
the Securityholders  thereunder.  In such event, the legal expenses and costs of
such action and any liability  resulting  therefrom will be expenses,  costs and
liabilities  of the  Securityholders,  and such  Servicer will be entitled to be
reimbursed therefor from 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, will be the successor of the Servicer
or the Depositor, as the case may be, under the applicable Agreement.

      Special Servicers

      If and to the extent  specified in the related  prospectus  supplement,  a
special  servicer  (a  "Special  Servicer")  may be a  party  to the  applicable
Agreement  or may be appointed  by the  Servicer or another  specified  party to

                                       61



perform certain  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 the related  Agreement.
The Servicer will be liable for the  performance of a Special  Servicer only if,
and to the extent,  set forth in such Agreement.  Each Special  Servicer will be
required to deliver,  to the extent  applicable,  the documents  described under
"--Evidence as to Compliance."

      Events of Default under the Agreements

      Events of default under the applicable  Agreement  will generally  include
(i) any failure by the  Servicer to remit to the  Trustee  for  distribution  to
Securityholders,  any required  payment that continues after a grace period,  if
any; (ii) any failure by the Servicer duly to observe or perform in any material
respect any of its other covenants or obligations under the applicable Agreement
which continues  unremedied for 30 days after written notice of such 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;  (iii) any breach of a representation or warranty made by the
Servicer under the applicable  Agreement which materially and adversely  affects
the interests of  Securityholders  and which  continues  unremedied  for 30 days
after  written  notice of such  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  Securities  evidencing  not less than 25% of the Voting  Rights;
(iv) certain events of insolvency,  readjustment  of debt,  marshaling of assets
and  liabilities or similar  proceedings  and certain actions by or on behalf of
the Servicer indicating its insolvency or inability to pay its obligations;  and
(v)  if  specified  in  the  applicable  prospectus  supplement,  a  delinquency
percentage   exceeding  a  percentage   specified  in  the  related   prospectus
supplement.  Material  variations to the foregoing events of default (other than
to shorten cure periods or eliminate notice  requirements)  will be specified in
the related prospectus supplement..

      The manner of  determining  the "Voting  Rights" of a Security or Class or
Classes of Securities will be specified in the related prospectus supplement.

      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  Securities
generally  evidencing not less than 51% of the Voting Rights,  the Trustee shall
terminate all of the rights and obligations of the Servicer under the applicable
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
applicable  Agreement  (except  that if the  Trustee is  prohibited  by law from
obligating  itself  to make  advances  regarding  delinquent  Assets,  or if the
related  prospectus  supplement  so  specifies,  then  the  Trustee  will not be
obligated to make such  advances)  and will be entitled to similar  compensation
arrangements. In the event that the Trustee is unwilling or unable so to act, it
may or, at the written request of the holders of Securities  generally  entitled
to at least 51% of the Voting Rights,  it shall 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 such appointment
of at  least  $15,000,000  (or  such  other  amount  specified  in  the  related
prospectus  supplement) to act as successor to the Servicer under the applicable
Agreement.  Pending  such  appointment,  the Trustee is obligated to act in such
capacity.  The  Trustee  and any such  successor  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 applicable Agreement.

      The Trustee or a successor  servicer is entitled to be reimbursed  for its
costs in effecting a servicing  transfer from the predecessor  servicer.  In the
event that the predecessor  servicer fails to reimburse the Trustee or successor
servicer,  the Trustee or successor  servicer will be entitled to  reimbursement
from the assets of the related Trust.

      The holders of Securities  representing  generally at least 66 2/3% of the
Voting Rights allocated to the respective Classes of Securities  affected by any
event of default  will be  entitled  to waive such event of  default;  provided,
however,  that an Event of Default  involving a failure to distribute a required
payment to  Securityholders  described in clause (i) under  "--Events of Default
under the Agreements" may be waived only by all of the Securityholders. Upon any
such waiver of an event of default,  such event of default  shall cease to exist
and shall be deemed to have been remedied for every purpose under the applicable
Agreement.

                                       62



      No  Securityholders  will have the right under any  Agreement to institute
any proceeding with respect  thereto unless such holder  previously has given to
the  Trustee  written  notice of default  and unless the  holders of  Securities
generally  evidencing  not less than 25% of the Voting  Rights have made written
request upon the Trustee to institute such proceeding in its own name as Trustee
thereunder and have offered to the Trustee reasonable indemnity, and the Trustee
for 60 days has  neglected  or refused to  institute  any such  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
thereunder or to institute,  conduct or defend any  litigation  thereunder or in
relation   thereto  at  the   request,   order  or   direction  of  any  of  the
Securityholders  covered by such  Agreement,  unless such  Securityholders  have
offered to the  Trustee  reasonable  security  or  indemnity  against the costs,
expenses and liabilities which may be incurred therein or thereby.

      Amendment

      Each Agreement may be amended by the parties thereto,  without the consent
of any  Securityholders  covered by the  applicable  Agreement,  (i) to cure any
ambiguity  or  mistake,  (ii) to correct,  modify or  supplement  any  provision
therein which may be inconsistent  with any other provision  therein or with the
related prospectus  supplement,  (iii) to make any other provisions with respect
to matters or questions  arising under the  applicable  Agreement  which are not
materially  inconsistent with the provisions thereof, or (iv) to comply with any
requirements  imposed by the Code;  provided  that, in the case of clause (iii),
such amendment will not adversely  affect in any material  respect the interests
of any Securityholders  covered by the applicable  Agreement as evidenced either
by an  opinion  of  counsel to such  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 Securities of the related Series to the
effect that such  amendment or  supplement  will not cause such Rating Agency to
lower or withdraw  the then current  rating  assigned to such  Securities.  Each
Agreement  may also be amended by the  Depositor,  the Servicer and the Trustee,
with the consent of the  Securityholders  affected thereby generally  evidencing
not less than 51% of the Voting Rights, for any purpose;  provided,  however, no
such  amendment  may (i) reduce in any manner the amount of, or delay the timing
of, payments received or advanced on Assets which are required to be distributed
on any  Security  without the consent of the  Securityholder  or (ii) reduce the
consent  percentages  described in this paragraph without the consent of all the
Securityholders  covered  by such  Agreement  then  outstanding.  However,  with
respect to any Series of Securities as to which a REMIC  election is to be made,
the Trustee will not consent to any amendment of the applicable Agreement unless
it shall  first have  received  an  opinion  of counsel to the effect  that such
amendment  will not result in the  imposition of a tax on the related Trust Fund
or cause the  related  Trust Fund to fail to qualify as a REMIC at any time that
the related Securities are outstanding.

      The Trustee

      The Trustee under each Agreement  will be named in the related  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.  With respect to certain Series of
Securities, a securities administrator will perform certain duties and functions
normally performed by the Trustee. Any securities  administrator will be a party
to the  applicable  Agreement  and will be named  in the  applicable  prospectus
supplement.  Any  securities  administrator  will have  obligations  and  rights
similar to the Trustee as described in this Prospectus.

      Duties of the Trustee

      The Trustee will make no representations as to the validity or sufficiency
of any  Agreement,  the  Securities 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  Securities
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 applicable  Agreement.  However, upon receipt of
the various certificates,  reports or other instruments required to be furnished
to it, the  Trustee is  required  to examine  such  documents  and to  determine
whether they conform to the requirements of the applicable Agreement.

                                       63



      Certain Matters Regarding the Trustee

      The Trustee and any  director,  officer,  employee or agent of the Trustee
shall be reimbursed by the Trust Fund for all reasonable expenses, disbursements
and  advances  incurred  or made by the  Trustee in  accordance  with any of the
provisions of the applicable  Agreement  (including the reasonable  compensation
and the  expenses  and  disbursements  of its  counsel  and of all  persons  not
regularly in its employ) except any such expense, disbursement or advance as may
arise  from its  negligence  or bad  faith or  which  is the  responsibility  of
Securityholders or the Trustee under the Agreement. In addition, the Trustee and
its officers, directors,  employees and agents shall be indemnified by the Trust
Fund from, and held harmless against, any and all losses, liabilities,  damages,
claims or expenses  incurred in connection with any legal action relating to the
applicable  Agreement  or the  Securities,  other  than any loss,  liability  or
expense  incurred by reason of willful  misfeasance,  bad faith or negligence of
the  Trustee in the  performance  of its duties  thereunder  or by reason of the
Trustee's reckless disregard of obligations and duties thereunder.

      Resignation and Removal of the Trustee

      The Trustee may at any time resign from its  obligations  and duties under
an Agreement by giving written notice thereof to the Depositor, the Servicer and
all Securityholders. Upon receiving such notice of resignation, the Depositor is
required promptly to appoint a successor trustee acceptable to the Servicer.  If
no successor trustee shall have been so appointed and have accepted  appointment
within 30 days after the giving of such  notice of  resignation,  the  resigning
Trustee may petition any court of competent  jurisdiction for the appointment of
a successor trustee.

      If at any time the Trustee  shall cease to be eligible to continue as such
under the  applicable  Agreement,  or if at any time the  Trustee  shall  become
incapable of acting, or shall be adjudged  bankrupt or insolvent,  or a receiver
of the Trustee or of its  property  shall be  appointed,  or any public  officer
shall take  charge or control of the  Trustee or of its  property or affairs for
the purpose of  rehabilitation,  conservation or liquidation,  or if a change in
the financial  condition of the Trustee has adversely affected or will adversely
affect the rating on any Class of the Securities,  then the Depositor may remove
the  Trustee  and  appoint  a  successor  trustee  acceptable  to the  Servicer.
Securityholders  of any Series generally  entitled to at least 51% of the Voting
Rights for such  Series may at any time  remove the  Trustee  without  cause and
appoint a successor trustee.

      Any costs  associated  with the  appointment  of a  successor  trustee are
required  to be  paid by the  predecessor  Trustee  and,  if not  paid,  will be
reimbursed  to the person  incurring  such costs from the assets of the  related
Trust Fund.  Notwithstanding the foregoing,  if the predecessor Trustee has been
removed by a vote of the holders of the  Securities as provided in the paragraph
above, any costs associated with the appointment of a successor  trustee will be
reimbursed  to the party  incurring  such costs  from the assets of the  related
Trust Fund.

      Any  resignation or removal of the Trustee and  appointment of a successor
trustee  shall not become  effective  until  acceptance  of  appointment  by the
successor trustee.

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
the specific provisions of the Indenture relating to such Series. The provisions
of each  Indenture  will vary  depending upon the nature of the Securities to be
issued  thereunder  and the  nature  of the  related  Trust  Fund.  A form of an
Indenture  has been filed as an exhibit to the  Registration  Statement of which
this prospectus is a part.

      Events of Default

      Events  of  default  under the  Indenture  for each  Series of Notes  will
generally include:  (i) a default for thirty (30) days or more in the payment of
any principal of or interest on any Note of such Series; (ii) failure to perform
any other covenant of the Trust in the Indenture which continues for a period of
sixty (60) days after notice thereof

                                       64



is given in accordance with the procedures  described in the related  prospectus
supplement;  (iii)  any  representation  or  warranty  made by the  Trust in the
Indenture or in any certificate or other writing  delivered  pursuant thereto or
in  connection  therewith  with respect to or affecting  such Series having been
incorrect  in a material  respect as of the time  made,  and such  breach is not
cured within sixty (60) days after notice  thereof is given in  accordance  with
the  procedures  described in the related  prospectus  supplement;  (iv) certain
events of bankruptcy,  insolvency,  receivership or liquidation of the Depositor
or the Trust;  or (v) 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,  either  the  Indenture  Trustee or the
Securityholders  of a majority of the then aggregate  outstanding  amount of the
Notes of such Series may declare the principal  amount (or, if the Notes of that
Series are Accrual  Securities,  such portion of the principal  amount as may be
specified  in the terms of that  Series,  as provided in the related  prospectus
supplement)  of all the Notes of such Series to be due and payable  immediately.
Such declaration may, under certain circumstances,  be rescinded and annulled by
the  Securityholders of a majority in aggregate  outstanding amount of the Notes
of such Series.

      If, following an event of default with respect to any Series of Notes, the
Notes of such Series have been  declared to be due and  payable,  the  Indenture
Trustee may, in its  discretion,  notwithstanding  such  acceleration,  elect to
maintain  possession of the collateral  securing the Notes of such Series and to
continue  to apply  distributions  on such  collateral  as if there  had been no
declaration of acceleration if such collateral  continues to provide  sufficient
funds for the payment of  principal  of and interest on the Notes of such Series
as they  would  have  become  due if there had not been such a  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 such
Series for thirty (30) days or more, unless (a) the  Securityholders  of 100% of
the then  aggregate  outstanding  amount of the Notes of such Series  consent to
such sale, (b) the proceeds of such sale or liquidation are sufficient to pay in
full the principal of and accrued  interest,  due and unpaid, on the outstanding
Notes of such  Series  at the  date of such  sale or (c) the  Indenture  Trustee
determines that such  collateral  would not be sufficient on an ongoing basis to
make all payments on such Notes as such  payments  would have become due if such
Notes had not been declared due and payable,  and the Indenture  Trustee obtains
the consent of the Securityholders of 66 2/3% of the then aggregate  outstanding
amount of the Notes of such Series.

      In the event that the  Indenture  Trustee  liquidates  the  collateral  in
connection with an event of default  involving a default for thirty (30) days 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 such liquidation for unpaid fees and expenses. As a result, upon
the  occurrence  of  such  an  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 such an event of default.

      To the extent provided in the related prospectus supplement,  in the event
the principal of the Notes of a Series is declared due and payable, as described
above, the  Securityholders  of any such Notes issued at a discount from par may
be  entitled  to  receive no more than an amount  equal to the unpaid  principal
amount thereof less the amount of such discount which is unamortized.

      Subject to the  provisions of the Indenture  relating to the duties of the
Indenture  Trustee,  in case an event of default  shall occur and be  continuing
with  respect  to a Series of Notes,  the  Indenture  Trustee  shall 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 such Series,  unless such
holders offered to the Indenture  Trustee security or indemnity  satisfactory to
it against the costs,  expenses and liabilities which might be incurred by it in
complying  with such  request  or  direction.  Subject  to such  provisions  for
indemnification  and  certain  limitations  contained  in  the  Indenture,   the
Securityholders  of a majority of the then aggregate  outstanding  amount of the
Notes of such Series  shall 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 such Series,  and the  Securityholders of a majority of the then
aggregate  outstanding amount of the Notes of such Series may, in certain cases,
waive any  default  with  respect  thereto,  except a default in the  payment of
principal  or

                                       65



interest or a default in respect of a covenant  or  provision  of the  Indenture
that cannot be modified without the waiver or consent of all the Securityholders
of the outstanding Notes of such Series affected thereby.

      Discharge of Indenture

      The Indenture will be discharged with respect to a Series of Notes (except
with respect to certain  continuing  rights specified in the Indenture) upon the
delivery  to the  Indenture  Trustee for  cancellation  of all the Notes of such
Series or, with certain limitations,  upon deposit with the Indenture Trustee of
funds sufficient for the payment in full of all of the Notes of such Series.

      In addition to such discharge with certain limitations, the Indenture will
provide  that,  if so  specified  with  respect to the Notes of any Series,  the
related Trust Fund will be discharged from any and all obligations in respect of
the Notes of such Series (except for certain  obligations  relating to temporary
Notes and exchange of Notes,  to register  the transfer of or exchange  Notes of
such  Series,  to replace  stolen,  lost or mutilated  Notes of such 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  thereof 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 such Series on the maturity  date
for such Notes and any  installment of interest on such Notes in accordance with
the terms of the  Indenture  and the Notes of such  Series.  In the event of any
such defeasance and discharge of Notes of such Series,  holders of Notes of such
Series would be able to look only to such money and/or  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  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  certain  indebtedness  owing  by such  Trust to the
applicable Indenture Trustee in its individual capacity,  the property and funds
physically  held by such  Indenture  Trustee as such and any action  taken by it
that materially affects such Notes and that has not been previously reported.

      The Indenture Trustee

      The  Indenture  Trustee  for a Series of Notes  will be  specified  in the
related prospectus  supplement.  The Indenture Trustee for any Series may resign
at any time,  in which  event  the  Depositor  will be  obligated  to  appoint a
successor  trustee  for such  Series.  The  Depositor  may also  remove any such
Indenture Trustee if such Indenture Trustee ceases to be eligible to continue as
such under the related Indenture or if such Indenture Trustee becomes insolvent.
In such  circumstances  the  Depositor  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 such 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.

                          DESCRIPTION OF CREDIT SUPPORT

      Credit  enhancement  may  be  provided  with  respect  to  any  Series  of
Securities only in one or more of the methods  described  below.  The applicable
prospectus   supplement   will  describe  the  material  terms  of  such  credit
enhancement,  including  any  limits on the  timing  or  amount  of such  credit
enhancement  or any conditions  that must be met before such credit  enhancement
may be  accessed.  If the  provider  of the  credit  enhancement  is  liable  or
contingently  liable to provide  payments  representing  10% or more of the cash
flow  supporting  any offered Class of  Securities,  the  applicable  prospectus
supplement will disclose the name of the provider,  the  organizational  form of
the  provider,  the general  character  of the  business of the provider and the
financial  information  required by Item

                                       66



1114(b)(2) of Regulation AB (17 CFR 229.1114).  Copies of the limited guarantee,
financial  guaranty  insurance  policy,  surety  bond,  letter of  credit,  pool
insurance policy,  mortgagor bankruptcy bond, special hazard insurance policy or
Cash Flow  Agreement,  if any,  relating to a Series of Securities will be filed
with the Commission as an exhibit to a Current Report on Form 8-K.

Subordination

      If provided in the applicable prospectus  supplement,  one or more Classes
of Senior  Securities  will be  entitled  to receive  all or a  disproportionate
percentage  of the payments of principal  that are  received  from  borrowers in
advance  of  their  scheduled  due  dates  and are not  accompanied  by  amounts
representing  scheduled  interest  due after the months of those  payments or of
other unscheduled  principal receipts or recoveries in the percentages and under
the  circumstances  or for the periods  specified in the  applicable  prospectus
supplement.   This  type  of  allocation  of  principal   prepayments  or  other
unscheduled  receipts or recoveries relating to principal to this Class or these
Classes  of  Senior   Securities  will  have  the  effect  of  accelerating  the
amortization of these Senior Securities while increasing the interests evidenced
by the  Subordinated  Securities in the Trust Fund.  Increasing the interests of
the  Subordinated  Securities  relative  to that  of the  Senior  Securities  is
intended to  preserve  the  availability  of the  subordination  provided by the
Subordinated Securities.

      If specified in the applicable  prospectus  supplement,  the rights of the
holders  of the  Subordinated  Securities  of a Series of  Securities  for which
credit  enhancement is provided through  subordination to receive  distributions
with respect to the Assets in the related Trust Fund will be subordinated to the
rights  of the  holders  of the  Senior  Securities  of the  same  Series.  This
subordination  is  intended  to enhance  the  likelihood  of regular  receipt by
holders of Senior Securities of the full amount of scheduled monthly payments of
principal and interest due them and to provide limited protection to the holders
of the Senior Securities against losses due to obligor defaults.

      The protection afforded to the holders of Senior Securities of a Series of
Securities for which credit enhancement is provided by the subordination feature
described above will be effected by (i) the preferential  right of these holders
to receive,  prior to any  distribution  being made to the related  Subordinated
Securities  on each  Distribution  Date,  current  distributions  on the related
Assets of principal and interest due them on each  Distribution  Date out of the
funds  available  for  distribution  on that  date in the  related  Distribution
Account,  (ii) by the right of these holders to receive future  distributions on
the Assets that would otherwise have been payable to the holders of Subordinated
Securities  and/or (iii) by the prior allocation to the Subordinated  Securities
of all or a portion of losses realized on the related Assets.

      Losses  realized on  liquidated  Assets  (other than,  if specified in the
applicable  prospectus  supplement,  Excess Special Hazard Losses,  Excess Fraud
Losses and Excess Bankruptcy Losses as described below) will be allocated to the
holders  of  Subordinated  Securities  through  a  reduction  of the  amount  of
principal  payments on the Assets to which these holders are entitled before any
corresponding reduction is made in respect of the Senior Security.

      A "Special  Hazard  Loss" is a loss on a liquidated  Asset  occurring as a
result of a hazard not insured against under a standard hazard  insurance policy
of the type described below under "Description of the Agreements--Material Terms
of   the   Pooling   and   Servicing   Agreements   and   Underlying   Servicing
Agreements--Hazard Insurance Policies." A "Fraud Loss" is a loss on a liquidated
Asset due to fraud in the  origination of that Asset.  A "Bankruptcy  Loss" is a
loss on a liquidated Asset attributable to certain actions which may be taken by
a  bankruptcy  court in  connection  with a Asset,  including a  reduction  by a
bankruptcy court of the principal balance of or the interest rate on an Asset or
an  extension of its  maturity.  Special  Hazard  Losses in excess of the amount
specified in the  applicable  prospectus  supplement  (the "Special  Hazard Loss
Amount"),  if any, are "Excess Special Hazard Losses." Fraud Losses in excess of
the amount  specified in the applicable  prospectus  supplement (the "Fraud Loss
Amount"),  if any, are "Excess Fraud Losses." Bankruptcy Losses in excess of the
amount specified in the applicable  prospectus  supplement (the "Bankruptcy Loss
Amount"),  if any, are "Excess  Bankruptcy  Losses." Any Excess  Special  Hazard
Losses,  Excess  Fraud Losses or Excess  Bankruptcy  Losses for a Series will be
allocated  on a  pro  rata  basis  among  the  related  Classes  of  Senior  and
Subordinated Securities. An allocation of a loss on a "pro rata" basis among two
or more Classes of Securities means an allocation on a pro rata basis to each of
those  Classes of  Securities  on the basis of their  then-outstanding  Security
Balances  in the case of the  principal  portion  of a loss or based on  accrued
interest in the case of an interest portion of a loss.

                                       67



      Since the Special  Hazard Loss  Amount,  Fraud Loss Amount and  Bankruptcy
Loss Amount,  if any, for a Series of  Securities  are each  expected to be less
than the amount of principal  payments on the Assets to which the holders of the
Subordinated  Securities  of the Series are  initially  entitled  (the amount of
principal  payments being subject to reduction,  as described above, as a result
of allocation of losses on liquidated Assets that are not Special Hazard Losses,
Fraud Losses or Bankruptcy  Losses),  the holders of Subordinated  Securities of
that  Series  will bear the risk of  Special  Hazard  Losses,  Fraud  Losses and
Bankruptcy  Losses  to a lesser  extent  than they  will  bear  other  losses on
liquidated Assets.

      Although the subordination  feature described above is intended to enhance
the  likelihood  of timely  payment of principal  and interest to the holders of
Senior  Securities,  shortfalls  could  result  in  certain  circumstances.  For
example,  a shortfall in the payment of principal  otherwise  due the holders of
Senior  Securities  could occur if losses realized on the Assets in a Trust Fund
were exceptionally high and were concentrated in a particular month.

      The holders of Subordinated  Securities will not be required to refund any
amounts previously properly distributed to them, regardless of whether there are
sufficient funds on a subsequent  Distribution  Date to make a full distribution
to holders of each Class of Senior Securities of the same Series.

Limited Guarantee

      If  specified in the  prospectus  supplement  for a Series of  Securities,
credit  enhancement may be provided in the form of a limited guarantee issued by
a guarantor named in that prospectus supplement. The limited guarantee may cover
deficiencies in amounts  otherwise payable on some or all of the Securities of a
Series. The limited guarantee may cover timely distributions of interest or full
distributions  of  principal  or both on the basis of a  schedule  of  principal
distributions  set forth in or determined in the manner specified in the related
prospectus  supplement.  The limited guarantee may provide additional protection
against  losses on the  Assets  included  in a Trust  Fund,  provide  payment of
administrative  expenses,  or  establish  a  minimum  reinvestment  rate  on the
payments made on the Assets or principal  payment rate on the Assets.  A limited
guarantee  will be limited in amount to the dollar  amount or  percentage of the
principal  balance  of the  Assets or  Securities  specified  in the  applicable
prospectus supplement.

Financial Guaranty Insurance Policy or Surety Bond

      If  specified in the  prospectus  supplement  for a Series of  Securities,
credit enhancement may be provided in the form of a financial guaranty insurance
policy or a surety bond issued by one or more insurers named in that  prospectus
supplement. The financial guaranty insurance policy will guarantee, with respect
to one or more Classes of Securities of the related Series, timely distributions
of interest and ultimate distributions of principal at the dates set forth in or
determined in the manner specified in the prospectus supplement. If specified in
the prospectus  supplement,  the financial  guaranty  insurance policy will also
guarantee  against any payment  made to a  Securityholder  that is  subsequently
recovered as a preferential transfer under the Bankruptcy Code.

Letter of Credit

      If  specified in the  prospectus  supplement  for a Series of  Securities,
credit  enhancement  may be provided  by a letter of credit  issued by a bank or
other financial institution  specified in the applicable prospectus  supplement.
Under the letter of  credit,  the  provider  will be  obligated  to pay up to an
aggregate fixed dollar amount, net of previous drawings on the letter,  equal to
the percentage  specified in the prospectus  supplement of the unpaid  principal
balance of the Assets or of one or more Classes of  Securities.  If specified in
the prospectus supplement, the letter of credit may permit drawings in the event
of losses not covered by  insurance  policies or other credit  support,  such as
losses arising from damage not covered by standard  hazard  insurance  policies,
losses  resulting  from the  bankruptcy  of a borrower  and the  application  of
certain  provisions of the Bankruptcy  Code, or losses  resulting from denial of
insurance coverage due to  misrepresentations in connection with the origination
of an Asset. The amount available under the letter of credit will, in all cases,
be reduced to the  extent of the  unreimbursed  payments  previously  paid.  The
obligations  of the  provider  under the  letter of  credit  for each  Series of
Securities  will expire at the earlier of the date  specified in the  prospectus
supplement or the termination of the Trust.

                                       68



Pool Insurance Policy

      If  specified  in  the  prospectus  supplement  relating  to a  Series  of
Securities,  credit  enhancement  may be provided by a mortgage  pool  insurance
policy for the Mortgage  Loans in the related  Trust Fund.  Each  mortgage  pool
insurance  policy,  in  accordance  with  the  limitations   described  in  this
prospectus and in the prospectus supplement, if any, will cover all or a portion
of any loss by reason of  default  on a  Mortgage  Loan in an amount  equal to a
percentage  specified  in the  applicable  prospectus  supplement  of the unpaid
principal  balance of the Mortgage  Loans. As described under "Material Terms of
the   Pooling   and    Servicing    Agreements    and    Underlying    Servicing
Agreements--Due-on-Sale Provisions," the Servicer or the Master Servicer, as the
case may be,  generally will be required to use its best efforts to maintain the
mortgage pool insurance  policy and to present  claims to the pool insurer.  The
mortgage pool insurance  policies,  however,  are not blanket  policies  against
loss,  since claims may only be made respecting  particular  defaulted  Mortgage
Loans and only upon  satisfaction of specified  conditions  precedent  described
below. The mortgage pool insurance  policies will generally not cover losses due
to a  failure  to pay or denial of a claim  under a primary  mortgage  insurance
policy, regardless of the reason for nonpayment.

      As more specifically provided in the related prospectus  supplement,  each
mortgage pool insurance  policy will provide for  conditions  under which claims
may be  presented  and covered  under the  policy.  Upon  satisfaction  of these
conditions,  the pool  insurer  will have the option  either (a) to purchase the
property  securing the  defaulted  Mortgage  Loan at a price equal to its unpaid
principal  balance plus accrued and unpaid  interest at the applicable  Mortgage
Interest Rate to the date of purchase plus certain  Advances,  or (b) to pay the
amount  by  which  the sum of the  unpaid  principal  balance  of the  defaulted
Mortgage Loan plus accrued and unpaid interest at the Mortgage  Interest Rate to
the date of payment of the claim plus  certain  Advances  exceeds  the  proceeds
received from an approved sale of the Mortgaged Property,  in either case net of
certain  amounts  paid or assumed to have been paid  under any  related  primary
mortgage insurance policy.

      Securityholders  may  experience  a  shortfall  in the amount of  interest
payable on the related Securities in connection with the payment of claims under
a mortgage pool  insurance  policy  because the pool insurer is only required to
remit unpaid  interest  through the date a claim is paid rather than through the
end of the month in which the claim is paid.  In addition,  Securityholders  may
also experience losses with respect to the related Securities in connection with
payments  made under a mortgage  pool  insurance  policy to the extent  that the
related  Servicer  expends  funds to cover unpaid real estate taxes or to repair
the related  Mortgaged  Property in order to make a claim under a mortgage  pool
insurance  policy,  as those  amounts will not be covered by payments  under the
policy and will be  reimbursable  to the related  Servicer from funds  otherwise
payable to the  Securityholders.  If any Mortgaged Property securing a defaulted
Mortgage Loan is damaged and proceeds,  if any from the related hazard insurance
policy or applicable special hazard insurance policy are insufficient to restore
the damaged  property to a condition  sufficient  to permit  recovery  under the
mortgage pool  insurance  policy,  a Servicer will  generally not be required to
expend its own funds to restore the damaged  property  unless it determines that
(a) restoration  will increase the proceeds to one or more Classes of Securities
on liquidation of the Mortgage Loan after  reimbursement of the related Servicer
for its  expenses  and (b)  the  expenses  will  be  recoverable  by it  through
Liquidation Proceeds or insurance proceeds.

      A mortgage  pool  insurance  policy and some  primary  mortgage  insurance
policies will generally not insure against loss sustained by reason of a default
arising from,  among other things,  fraud or  negligence in the  origination  or
servicing of a Mortgage Loan, including  misrepresentation by the mortgagor, the
seller or other  persons  involved  in the  origination  of the  Mortgage  Loan,
failure  to  construct  a  mortgaged  property  in  accordance  with  plans  and
specifications  or  bankruptcy,  unless as specified  in the related  prospectus
supplement,  an endorsement to the mortgage pool insurance  policy  provides for
insurance against that type of loss.

      The original amount of coverage under each mortgage pool insurance  policy
will be  reduced  over the  life of the  related  Series  of  Securities  by the
aggregate  amount of claims paid less the aggregate of the net amounts  realized
by the pool insurer upon disposition of all foreclosed properties. The amount of
claims paid includes some  expenses  incurred by the related  Servicer or Master
Servicer as well as accrued interest on delinquent Mortgage Loans to the date of
payment of the  claim.  Accordingly,  if  aggregate  net  claims  paid under any
mortgage pool insurance  policy reach the original policy limit,  coverage under
that mortgage  pool  insurance  policy will be exhausted and any further  losses
will be borne by the  related  Securities,  to the extent  not  covered by other
credit enhancements.

                                       69



Special Hazard Insurance Policy

      Any insurance  policy covering  Special Hazard Losses obtained for a Trust
will be issued by the insurer named in the related prospectus  supplement.  Each
special hazard insurance policy will be subject to limitations described in this
paragraph and in the related prospectus supplement, if any, and will protect the
related  Securityholders  from Special Hazard Losses.  Aggregate  claims under a
special hazard  insurance  policy will be limited to the amount set forth in the
related  Pooling and  Servicing  Agreement or  Indenture  and will be subject to
reduction  as  described  in the related  Pooling  and  Servicing  Agreement  or
Indenture.  A special hazard  insurance policy will provide that no claim may be
paid unless hazard and, if applicable, flood insurance on the Mortgaged Property
securing the Mortgage Loan or  Manufactured  Home securing the Contract has been
kept in force and other protection and  preservation  expenses have been paid by
the related Servicer or Master Servicer, as the case may be.

      In accordance with the foregoing  limitations,  a special hazard insurance
policy will provide that, where there has been damage to the Mortgaged  Property
securing a foreclosed  Mortgage Loan or Manufactured  Home securing a foreclosed
Contract, title to which has been acquired by the insured, and to the extent the
damage is not covered by the hazard insurance policy or flood insurance  policy,
if any, maintained by the obligor or the related Servicer or Master Servicer, as
the case may be,  the  insurer  will pay the lesser of (i) the cost of repair or
replacement of the related Mortgaged  Property or Manufactured Home or (ii) upon
transfer of the property to the  insurer,  the unpaid  principal  balance of the
Mortgage  Loan or  Contract  Rate  at the  time of  acquisition  of the  related
property by foreclosure or deed in lieu of foreclosure, plus accrued interest at
the Mortgage  Interest Rate or Contract Rate to the date of claim settlement and
certain expenses  incurred by the related  Servicer or Master  Servicer,  as the
case may be, with  respect to the  related  Mortgaged  Property or  Manufactured
Home.

      If the Mortgaged  Property or Manufactured  Home is transferred to a third
party in a sale  approved by the  special  hazard  insurer,  the amount that the
special  hazard  insurer will pay will be the amount under (ii) above reduced by
the net proceeds of the sale of the Mortgaged  Property or Manufactured Home. If
the unpaid principal  balance plus accrued interest and certain Advances is paid
by the special hazard insurer,  the amount of further coverage under the related
special  hazard  insurance  policy  will be reduced by that  amount less any net
proceeds  from the sale of the  Mortgaged  Property or  Manufactured  Home.  Any
amount paid as the cost of repair of the property will further  reduce  coverage
by that amount.  Restoration of the property with the proceeds  described  under
(i) above will satisfy the condition  under any mortgage pool  insurance  policy
that the  property  be  restored  before a claim under the policy may be validly
presented  with respect to the  defaulted  Mortgage  Loan secured by the related
Mortgaged  Property or Contract  secured by the related  Manufactured  Home. The
payment described under (ii) above will render  presentation of a claim relating
to an Asset  under the  related  mortgage  pool  insurance  policy  unnecessary.
Therefore,  so long as a mortgage pool insurance  policy remains in effect,  the
payment by the insurer under a special  hazard  insurance  policy of the cost of
repair or of the unpaid  principal  balance of the  related  Asset plus  accrued
interest and certain Advances will not affect the total insurance  proceeds paid
to  Securityholders,  but will affect the relative amounts of coverage remaining
under the related  special hazard  insurance  policy and mortgage pool insurance
policy.

Mortgagor Bankruptcy Bond

      If specified in the related  prospectus  supplement,  a bankruptcy bond to
cover losses resulting from proceedings  under the federal  Bankruptcy Code with
respect to a Mortgage Loan will be issued by an insurer named in the  prospectus
supplement.  Each  bankruptcy  bond will cover,  to the extent  specified in the
related  prospectus  supplement,  certain losses resulting from a reduction by a
bankruptcy  court of scheduled  payments of principal and interest on a Mortgage
Loan or a reduction by the court of the unpaid  principal  balance of a Mortgage
Loan and will  cover  certain  unpaid  interest  on the  amount  of a  principal
reduction  from the date of the filing of a  bankruptcy  petition.  The required
amount of coverage under each  bankruptcy  bond will be set forth in the related
prospectus supplement.

Reserve Fund

      If specified in the applicable prospectus  supplement,  credit enhancement
with respect to a Series of Securities may be provided by the  establishment  of
one or more reserve  funds for the Series.  Any reserve fund for a Series may be
funded  (i) by a  deposit  of cash,  U.S.  Treasury  securities  or  instruments
evidencing  entitlements to

                                       70



principal or interest payments, letters of credit, demand notes, certificates of
deposit or a  combination  of these in the  aggregate  amount  specified  in the
applicable  prospectus  supplement  or (ii) by the deposit  from time to time of
certain amounts received on or in respect of the related Assets, as specified in
the applicable prospectus supplement.

      If  specified  in  the  prospectus   supplement,   reserve  funds  may  be
established to provide  limited  protection,  in an amount  satisfactory to each
Rating Agency,  against certain interest  shortfalls  arising from the timing of
principal prepayments, certain types of losses not covered by insurance policies
or other  credit  support,  such as losses  arising  from  damage not covered by
standard hazard  insurance  policies,  losses resulting from the bankruptcy of a
borrower and the  application of certain  provisions of the  Bankruptcy  Code or
losses   resulting   from  denial  of   insurance   coverage  due  to  fraud  or
misrepresentation in connection with the origination of an Asset. Following each
Distribution  Date amounts in a reserve  fund in excess of any required  reserve
fund amount 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 related Securities.

      If specified in the  prospectus  supplement,  any  reinvestment  income or
other gain from investments in certain investments  acceptable to the applicable
Rating Agencies will be credited to the related reserve fund for the Series, and
any loss resulting from the investments will be charged to the reserve fund. The
reserve fund for a Series will not be a part of the Trust Fund.

      Additional  information  concerning  any reserve fund will be set forth in
the prospectus  supplement,  including the initial  balance of the reserve fund,
the required reserve fund balance to be maintained, 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.

Cross Collateralization

      If specified  in the  applicable  prospectus  supplement,  the  beneficial
ownership of separate groups of Assets included in a Trust Fund may be evidenced
by separate Classes of Securities.  In this case, credit support may be provided
by a cross  collateralization  feature which requires that distributions be made
to certain  Classes from Asset  payments that would  otherwise be distributed to
Subordinated Securities evidencing a beneficial ownership interest in other loan
groups within the same Trust Fund. As a result, the amount of credit enhancement
available to a Class of Securities  against future losses on the Assets in which
that Class  represents  an interest  may be reduced as the result of losses on a
group of Assets in which that Class has no interest.  The applicable  prospectus
supplement  for a Series that  includes a cross  collateralization  feature will
describe its specific operation.

Overcollateralization

      If  specified  in  the  related   prospectus   supplement,   subordination
provisions  of a  Series  may be used to  accelerate  to a  limited  extent  the
amortization of one or more Classes of Securities  relative to the  amortization
of  the  related  Assets.  The  accelerated  amortization  is  achieved  by  the
application  of certain  excess  interest to the payment of  principal of one or
more Classes of Securities.  This acceleration feature creates,  with respect to
the Assets or a group of Assets,  overcollateralization  which  results from the
excess of the aggregate  principal  balance of the related  Assets,  or group of
Assets, over the Security Balance of the related Class or Classes of Securities.
This  acceleration may continue for the life of the related  Securities,  or may
have a shorter duration. In the case of limited acceleration,  once the required
level of  overcollateralization  is reached,  and subject to certain  provisions
specified  in the  related  prospectus  supplement,  this  limited  acceleration
feature  may  cease,   unless  necessary  to  maintain  the  required  level  of
overcollateralization.

Excess Interest

      If specified in the related prospectus  supplement,  the Assets in a Trust
may generate more  interest than is necessary to pay the interest  earned on the
Classes of Securities  each month.  The excess  interest may be used to maintain
overcollateralization,  to pay interest that was previously  earned but not paid
to certain Classes of Securities and to reimburse  certain Classes of Securities
for losses and certain shortfalls that they experienced previously.

                                       71



      If specified in the applicable prospectus supplement,  amounts received by
the  Trustee  under any Cash Flow  Agreement  described  below  under "Cash Flow
Agreements"  may  also be used to  provide  credit  enhancement  for one or more
Classes of Securities.

                              CASH FLOW AGREEMENTS

      If specified in the prospectus supplement, the Trust Fund may include cash
flow agreements  consisting only of one or more guaranteed investment contracts,
swap  agreements  or interest  rate cap or floor  agreements  (also called yield
maintenance  agreements),  each of which  agreements  is  intended to reduce the
effects of interest rate fluctuations on the assets or on one or more Classes of
Securities (each, a "Cash Flow Agreement"). The applicable prospectus supplement
will  describe  the  name,  organizational  form and  general  character  of the
business of the  counterparty  under any Cash Flow Agreement.  In addition,  the
prospectus  supplement  for the related  Series of Securities  will disclose the
significance  percentage,  calculated in accordance with Item 1115 of Regulation
AB (17 CFR 229.1115).  To the extent this percentage is (a) 10% or more but less
than 20%, the related prospectus supplement will provide financial data required
by Item 301 of  Regulation  S-K (17 CFR  229.301) or (b) greater  than 20%,  the
related prospectus supplement will provide financial statements required by Item
1115(b)(2) of Regulation AB (17 CFR 229.1115)  and, in either case,  the related
prospectus  supplement  will contain a description of the operation and material
terms of the Cash Flow Agreement,  including, without limitation,  conditions to
payment or limits on the timing or amount of payments  and  material  provisions
relating to the termination or  substitution of the Cash Flow Agreement.  Copies
of the Cash Flow Agreement,  if any,  relating to a Series of Securities will be
filed with the Commission as an exhibit to a Current Report on Form 8-K.

Guaranteed Investment Contracts

      If specified in the related prospectus  supplement,  the Trustee on behalf
of the  Trust  may  enter  into  one or more  guaranteed  investment  contracts.
Guaranteed  investment  contracts are generally  used to maximize the investment
income  on  funds  held  between  Distribution  Dates  pending  distribution  to
Securityholders.  Under a  guaranteed  investment  contract,  the  issuer of the
contract, which is typically a highly rated financial institution,  guarantees a
fixed or floating rate of interest over the life of the contract, as well as the
ultimate return of the principal.  Any payments  received from the issuer of the
contract by the Trust will be  distributed  to the  related  Class or Classes of
Securities as specified in the applicable prospectus supplement.

Yield Maintenance Agreements

      If specified in the related prospectus  supplement,  the Trustee on behalf
of the Trust will enter into one or more yield  maintenance  agreements in order
to support the yield of one or more Classes of Securities. The counterparty to a
yield  maintenance  agreement will receive an upfront payment and the Trust will
have no ongoing payment  obligations.  Generally,  if the index specified in the
applicable prospectus  supplement,  which index will be one-month,  three-month,
six-month  or  one-year  LIBOR,  CMT,  COFI,  MTA or the Prime  Rate,  exceeds a
percentage  for  a  particular  date  specified  in  the  applicable  prospectus
supplement, the counterparty to the yield maintenance agreement will be required
to pay to the Trustee an amount  equal to that excess  multiplied  by a notional
amount or the Security  Balance or Balances of one or more Classes of Securities
multiplied  by  one-twelfth.  This  amount may be adjusted to reflect the actual
number of days in the Interest  Accrual  Period for the related Class or Classes
of  Securities  and  will be paid to the  Class  or  Classes  of  Securities  as
specified in the related prospectus supplement.

Swap Agreements

      If specified in the related prospectus  supplement,  the Trustee on behalf
of the Trust  will enter into a swap  agreement  to support  the yield on one or
more  Classes  of  Securities.  Under  the swap  agreement,  the  Trust  will be
obligated to pay an amount equal to a certain  percentage  of a notional  amount
set forth in the related prospectus supplement to the counterparty and the Trust
will be entitled to receive an amount equal to one-month, three-month, six-month
or one-year LIBOR,  CMT, COFI, MTA or the Prime Rate on the notional amount from
the counterparty, until the swap agreement is terminated. Only the net amount of
the two obligations will be paid by the appropriate party. In the event that the
Trust is required to make a payment to the  counterparty,  that  payment will be
paid on the related Distribution Date prior to distributions to Securityholders.
Generally,  any payments  received  from the

                                       72



counterparty by the Trust will be distributed to cover certain shortfalls as set
forth in the applicable prospectus supplement.

      If specified in the related prospectus  supplement,  the Trustee on behalf
of the Trust will enter into one or more swap agreements to cover any shortfalls
on one or more Classes of Securities in the event those Securities are auctioned
to  third  party  investors  on a  date  specified  in  the  related  prospectus
supplement  and the  proceeds  from the  auction  are less than the  outstanding
Security  Balance of the  applicable  Class or Classes  of  Securities  plus any
accrued  and unpaid  interest.  In the event the  proceeds  from the auction are
greater  than the  outstanding  Security  Balance or  Security  Balances  of the
applicable  Class or Classes of Securities plus any accrued and unpaid interest,
this excess will be paid to the  counterparty or  counterparties  under the swap
agreement(s).  See "Risk  Factors--Amounts  Received  from  the  Auction and the
Swap Agreement May Be Insufficient to Assure  Completion of the Auction" and "--
Mandatory Auction of Securities" in this prospectus.

                     CERTAIN LEGAL ASPECTS OF MORTGAGE LOANS

      The following discussion contains summaries,  which are general in nature,
of certain  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. See "Description
of the Trust Funds--Assets."

General

      All of the  Mortgage  Loans  are  loans  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
upon  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
herein  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 such 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  mortgagor  (the borrower and 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
mortgagor),  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, "mortgagor" 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  mortgagor  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  such time as the  underlying  debt is  repaid,
generally with a power of sale as security for the indebtedness evidenced by the
related  mortgage note. In case the mortgagor  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 mortgagor.
At origination of a mortgage loan involving a land trust, the mortgagor 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,  certain federal laws (including,  without limitation,  the Relief Act)
and,  in some  cases,  in deed of  trust  transactions,  the  directions  of the
beneficiary.

                                       73



      The  Mortgages  that  encumber  Multifamily   Properties  may  contain  an
assignment of rents and leases,  pursuant to which the mortgagor  assigns to the
lender the  mortgagor'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  mortgagor  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,  such an 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 such lease.  An instrument  covering an interest in
real  property  other than the fee estate  requires  special  provisions  in the
instrument  creating such interest or in the mortgage,  deed of trust,  security
deed or deed to secure debt, to protect the  mortgagee  against  termination  of
such  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 related  prospectus  supplement  will make  certain  representations  and
warranties in the applicable Agreement or certain representations and warranties
will be assigned  to the Trustee  with  respect to any  Mortgage  Loans that are
secured  by  an  interest  in  a  leasehold  estate.   Such  representation  and
warranties, if applicable, will be set forth in the prospectus supplement.

Condominiums

      Certain of the Mortgage Loans may be loans secured by  condominium  units.
The condominium  building may be a multi-unit building or buildings,  or a group
of buildings whether or not attached to each other,  located on property subject
to condominium  ownership.  Condominium ownership is a form of ownership of real
property  as to which each owner is  entitled  to the  exclusive  ownership  and
possession  of his or her  individual  condominium  unit.  The owner also owns a
proportionate undivided interest in all parts of the condominium building (other
than the other  individual  condominium  units) and all areas or facilities,  if
any, for the common use of the condominium  units.  The condominium  unit owners
appoint  or elect the  condominium  association  to govern  the  affairs  of the
condominium.

Cooperatives

      Certain of the Mortgage Loans may be cooperative  loans.  The  Cooperative
either owns all the real property that comprises the project, including the land
and the apartment building comprised of separate dwelling units and common areas
or leases the land  generally by a long term ground lease and owns the apartment
building. The Cooperative is directly responsible for project management and, in
most cases, payment of real estate taxes and hazard and liability insurance.  If
there is a blanket  mortgage  on the  property  and/or  underlying  land,  as is
generally the case, the Cooperative,  as project mortgagor,  is also responsible
for meeting these mortgage  obligations.  Ordinarily,  the Cooperative  incurs a
blanket  mortgage  in  connection  with  the  construction  or  purchase  of the
Cooperative's   apartment   building.   The  interest  of  the  occupants  under
proprietary  leases or occupancy  agreements to which the Cooperative is a party
are generally  subordinate to the interest of the holder of the blanket mortgage
in that building.

      The Cooperative is owned by tenant  stockholders who, through ownership of
stock, shares or membership certificates in the corporation, receive proprietary
leases or occupancy  agreements which confer exclusive rights to occupy specific
units.  Generally,  a tenant  stockholder  of a Cooperative  must make a monthly
payment to the Cooperative representing such 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  rights  is  financed  through  a
cooperative  share loan evidenced by a promissory note and secured by a security
interest in the  occupancy  agreement  or  proprietary  lease and in the related
cooperative  shares.  The lender takes possession of the share certificate and a
counterpart of the  proprietary  lease or occupancy  agreement,  and typically 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

                                       74



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.

Leaseholds

      Mortgage  Loans may be secured by a mortgage on a ground lease.  Leasehold
mortgages are subject to certain  considerations  not  associated  with mortgage
loans secured by the fee estate of the mortgagor.  The most significant of these
consideration  is that the ground  lease  creating  the  leasehold  estate could
terminate,  leaving the leasehold  mortgagee  without its  security.  The ground
lease may  terminate,  if among other  reasons,  the ground  lessee  breaches or
defaults in its  obligations  under the ground lease or there is a bankruptcy of
the ground lessee or the ground lessor. This possibility may be minimized if the
ground lease contains certain  provisions  protective of the mortgagee,  but the
ground leases that secure Mortgage Loans may not contain all of these protective
provisions,  and mortgages may not contain the other protection discussed in the
next  paragraph.  Protective  ground lease  provisions  include the right of the
leasehold mortgagee to receive notices from the ground lessor of any defaults by
the mortgagor;  the right to cure those defaults, with adequate cure periods; if
a default is not  susceptible of cure by the leasehold  mortgagee,  the right to
acquire the leasehold  estate through  foreclosure or otherwise;  the ability of
the ground lease to be assigned to and by the  leasehold  mortgagee or purchaser
at a foreclosure  sale and for the  simultaneous  release of the ground lessee's
liabilities  under the new lease;  and the right of the  leasehold  mortgagee to
enter  into a new  ground  lease  with the  ground  lessor on the same terms and
conditions as the old ground lease upon a termination.

      In addition  to the  preceding  protections,  a  leasehold  mortgagee  may
require that the ground lease or leasehold  mortgage  prohibit the ground lessee
from treating the ground lease as terminated in the event of the ground lessor's
bankruptcy   and   rejection  of  the  ground  lease  by  the  trustee  for  the
debtor-ground  lessor. As further  protection,  a leasehold mortgage may provide
for the  assignment  of the  debtor-ground  lessee's  right  to  reject  a lease
pursuant to Section 365 of the Bankruptcy Code,  although the  enforceability of
that clause has not been established.  Without the protections  described in the
preceding paragraph,  a leasehold mortgagee may lose the collateral securing its
leasehold  mortgage.  In addition,  terms and conditions of a leasehold mortgage
are subject to the terms and  conditions of the ground lease.  Although  certain
rights  given to a ground  lessee  can be  limited  by the terms of a  leasehold
mortgage,  the rights of a ground lessee or a leasehold  mortgagee  with respect
to, among other things, insurance, casualty and condemnation will be governed by
the provisions of the ground lease.

Land Sale Contracts

      Under Land Sale Contracts 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 upon the extent
to which state courts are willing, or able 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 such a situation  does not have to  foreclose in order 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 such 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

                                       75



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 given 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 with respect to 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
certain 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.  Such 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 generally  designed to relieve the
mortgagor  from the legal effect of mortgage  defaults,  to the extent that such
effect is perceived as harsh or unfair. Relying on such 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 mortgagor's default and the likelihood that the mortgagor 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 in order to accommodate  mortgagors 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
mortgagor failed to maintain the mortgaged property  adequately or the mortgagor
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  mortgagor  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 mortgagor.

      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

                                       76



default by the  mortgagor  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, prior to
such sale, the trustee under a deed of trust must record a notice of default and
notice of sale and send a copy to the  mortgagor  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  mortgagor  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  mortgagor 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 such property
at the time of sale,  due to, among other  things,  redemption  rights which 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  accrued  and  unpaid   interest  plus  the  expenses  of
foreclosure.  Generally,  state law controls the amount of foreclosure costs and
expenses  which  may  be  recovered  by a  lender.  Thereafter,  subject  to the
mortgagor'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 such 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 upon 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, in the event that 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,  with respect to
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 certain 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 mortgagor is in default.  Any additional
proceeds are generally payable to the mortgagor.  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 such holders.

      Rights of Redemption

      The  purposes  of a  foreclosure  action  are to enable the  mortgagee  to
realize upon its security and to bar the mortgagor,  and all persons who have an
interest in the property which 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

                                       77



foreclosure  sale,  those having an interest which 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 been  commenced,  the  redeeming  party must pay certain
costs of such 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  which
exists prior to completion of the foreclosure, is not waivable by the mortgagor,
must be exercised prior to 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  mortgagor  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  mortgagor  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 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  calendar  years
following  the year the Trust Fund  acquired  the  property.  With  respect to a
Series of Securities  for which an election is made to qualify the Trust Fund or
a part  thereof as a REMIC,  the  applicable  Agreement  will permit  foreclosed
property  to be held for more  than  such  period  of time if the IRS  grants an
extension  of time within  which to sell such  property or  independent  counsel
renders an opinion to the effect that holding such property for such  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 by-laws, 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 such  tenant-stockholder,  including  mechanics'
liens   against   the   cooperative   apartment   building   incurred   by  such
tenant-stockholder.  The  proprietary  lease or  occupancy  agreement  generally
permit the  Cooperative  to  terminate  such lease or  agreement in the event an
obligor  fails to make  payments  or defaults in the  performance  of  covenants
required  thereunder.  Typically,  the lender and the  Cooperative  enter into a
recognition  agreement  which  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, in the event that the
tenant-stockholder  has  defaulted  under  the  proprietary  lease or  occupancy
agreement,  the  Cooperative  will  take no action to  terminate  such  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 such 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
thereon.

      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 Uniform  Commercial
Code ("UCC") and the security agreement  relating to those

                                       78



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.

      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 which 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 which apply to certain 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,  which are  subordinate  to first or other  senior  mortgages or deeds of
trust  held by other  lenders.  The  rights of the Trust Fund 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 mortgagor, 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" herein.

      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  mortgagor  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  such  sums,  such  sums will
generally have priority over all sums due under the junior mortgage.

Rights of Redemption

      The  purposes  of a  foreclosure  action  are to enable the  mortgagee  to
realize upon its security and to bar the mortgagor,  and all persons who have an
interest in the property which 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  which 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
been commenced, the redeeming party must pay certain costs of such 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  which
exists prior to completion of the foreclosure, is not waivable by the mortgagor,
must be exercised prior to 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  mortgagor  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

                                       79



of the foreclosure sale price. In other states,  redemption may be authorized if
the  former  mortgagor  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 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.

Anti-Deficiency  Legislation,  the  Bankruptcy  Code and  Other  Limitations  on
Lenders

      Certain  states  have  imposed  statutory  prohibitions  which  limit  the
remedies of a beneficiary under a deed of trust or a mortgagee under a mortgage.
In some  states,  statutes  limit the right of the  beneficiary  or mortgagee 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 in most cases to the  difference  between the
net amount realized upon the public sale of the real property and the amount due
to the lender.  Other statutes  require the  beneficiary or mortgagee to exhaust
the security  afforded  under a deed of trust or mortgage by  foreclosure  in an
attempt to satisfy the full debt before  bringing a personal  action against the
borrower.  Finally,  other statutory  provisions  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 beneficiary
or a mortgagee 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 United States Bankruptcy
Code, 11 U.S.C.  Sections 101 et seq. (the  "Bankruptcy  Code"),  and state laws
affording relief to debtors  (together with the Bankruptcy Code, the "Insolvency
Laws") may interfere with or affect the ability of a secured  mortgage lender to
obtain payment of a mortgage loan, to realize upon  collateral  and/or enforce a
deficiency  judgment.  For example,  under the  Bankruptcy  Code,  virtually all
actions (including  foreclosure actions and deficiency judgment proceedings) are
automatically stayed upon the filing of a bankruptcy petition,  and, usually, no
interest or  principal  payments  are made  during the course of the  bankruptcy
case.  Foreclosure  of an interest in real  property of a debtor in a case under
the Bankruptcy Code can typically occur only if the bankruptcy court vacates the
stay; an action the court may be reluctant to take,  particularly  if the debtor
has the prospect of restructuring  his or her debts and the mortgage  collateral
is not deteriorating in value. The delay and the consequences  thereof caused by
such automatic stay can be  significant.  Also,  under the Bankruptcy  Code, the
filing  of a  petition  in  bankruptcy  by or on  behalf  of a junior  lienor (a
subordinate  lender  secured by a mortgage  on the  property)  may stay a senior
lender from taking action to foreclose.

      A homeowner  may file for relief  under the  Bankruptcy  Code under any of
three different  chapters of the Bankruptcy Code. Under Chapter 7, the assets of
the debtor are liquidated and a lender secured by a lien may "bid in" (i.e., bid
up to the amount of the debt) at the sale of the asset. See  "--Foreclosure."  A
homeowner may also file for relief under Chapter 11 of the  bankruptcy  code and
reorganize   his  or  her  debts  through  his  or  her   reorganization   plan.
Alternatively,  a  homeowner  may  file  for  relief  under  Chapter  13 of  the
Bankruptcy Code and address his or her debts in a rehabilitation  plan. (Chapter
13 is often  referred  to as the "wage  earner  chapter" or  "consumer  chapter"
because  most  individuals  seeking to  restructure  their debts file for relief
under Chapter 13 rather than under Chapter 11.)

      The  Bankruptcy  Code permits a mortgage  loan that is secured by property
that does not consist solely of the debtor's principal  residence to be modified
without the consent of the lender  provided  certain  substantive and procedural
safeguards are met. Under the Bankruptcy  Code, the lender's  security  interest
may be reduced to the  then-current  value of the property as  determined by the
court if the value is less than the amount due on the loan,  thereby leaving the
lender as a general unsecured  creditor for the difference  between the value of
the  collateral and the  outstanding  balance of the mortgage loan. A borrower's
unsecured  indebtedness  will  typically be discharged in full upon payment of a
substantially reduced amount. Other modifications to a mortgage loan may include
a reduction in the amount of each scheduled payment,  which reduction may result
from a  reduction  in the  rate of  interest,  an  alteration  of the  repayment
schedule,  an extension of the final  maturity  date,  and/or a reduction in the
outstanding   balance  of  the   secured   portion  of  the  loan.   In  certain
circumstances, subject to the court's approval, a

                                       80



debtor in a case under Chapter 11 of the  Bankruptcy  Code may have the power to
grant liens senior to the lien of a mortgage.

      A  reorganization  plan under Chapter 11 and a  rehabilitation  plan under
Chapter 13 of the Bankruptcy Code may each allow a debtor to cure a default with
respect to a mortgage loan on such debtor's  residence by paying arrearages over
a period of time and to  deaccelerate  and reinstate the original  mortgage loan
payment  schedule,  even  though  the  lender  accelerated  the loan and a final
judgment of foreclosure had been entered in state court (provided no sale of the
property had yet occurred)  prior to the filing of the debtor's  petition  under
the  Bankruptcy  Code.  Under a  Chapter  13 plan,  curing of  defaults  must be
accomplished  within the five year maximum term  permitted for repayment  plans,
such term commencing when the repayment plan becomes  effective,  while defaults
may be  cured  over a  longer  period  of  time  under  a  Chapter  11  plan  of
reorganization.

      Generally,  a repayment plan in a case under Chapter 13 may not modify the
claim of a mortgage  lender if the borrower  elects to retain the property,  the
property is the borrower's  principal residence and the property is the lender's
only  collateral.  Certain courts have allowed  modifications  when the mortgage
loan is secured both by the debtor's principal  residence and by collateral that
is not "inextricably bound" to the real property, such as appliances, machinery,
or furniture.  Certain courts have also allowed  modifications when the Mortgage
Loan is fully unsecured at the time of bankruptcy.

      The  general  protection  for  mortgages  secured  only  by  the  debtor's
principal  residence is not  applicable  in a case under  Chapter 13 if the last
payment  on the  original  payment  schedule  is due  before  the final date for
payment under the debtor's Chapter 13 plan (which date could be up to five years
after the debtor emerges from bankruptcy). Under several recently decided cases,
the terms of such a loan can be modified in the manner  described  above.  While
these  decisions  are  contrary  to the  holding  in a prior  case  by a  senior
appellate  court,  it is  possible  that the later  decisions  will  become  the
accepted  interpretation  in view of the  language of the  applicable  statutory
provision.  If  this  interpretation  is  adopted  by a  court  considering  the
treatment in a Chapter 13 repayment plan of a Mortgage Loan, it is possible that
the Mortgage Loan could be modified.

      State  statutes  and  general  principles  of  equity  may also  provide a
mortgagor  with means to halt a  foreclosure  proceeding  or sale and to force a
restructuring of a mortgage loan on terms a lender would not otherwise accept.

      In a bankruptcy or similar proceeding of a mortgagor,  action may be taken
seeking the recovery,  as a preferential  transfer or on other  grounds,  of any
payments  made by the  mortgagor  under the related  mortgage  loan prior to the
bankruptcy or similar  proceeding.  Payments on long-term  debt may be protected
from  recovery as  preferences  if they are payments in the  ordinary  course of
business  made on debts  incurred in the  ordinary  course of business or if the
value of the  collateral  exceeds the debt at the time of  payment.  Whether any
particular  payment  would be  protected  depends  upon the facts  specific to a
particular transaction.

      A trustee in  bankruptcy,  in some  cases,  may be entitled to collect its
costs and expenses in  preserving  or selling the  mortgaged  property  ahead of
payment to the lender.  Moreover,  the laws of certain states also give priority
to  certain  tax and  mechanics  liens  over the lien of a  mortgage.  Under the
Bankruptcy  Code,  if the court finds that  actions of the  mortgagee  have been
unreasonable  and  inequitable,   the  lien  of  the  related  mortgage  may  be
subordinated to the claims of unsecured creditors.

      The Bankruptcy  Code provides  priority to certain tax liens over the lien
of the mortgage. 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 applicable  laws. In some cases,  this liability may affect  assignees of
the Mortgage Loans.

                                       81



Enforceability of Certain Provisions

      Standard  forms of note,  mortgage  and  deed of trust  generally  contain
provisions  obligating  the  borrower to pay a late  charge if payments  are not
timely  made  and in some  circumstances  may  provide  for  prepayment  fees or
penalties if the obligation is paid prior to maturity.  In certain states, there
are or may be specific  limitations upon late charges which a lender may collect
from a borrower for delinquent  payments.  Certain states also limit the amounts
that a lender may collect from a borrower as an additional charge if the loan is
prepaid.

      Courts have imposed general equitable  principles upon foreclosure.  These
equitable  principles  are  generally  designed to relieve the borrower from the
legal effect of defaults under the loan documents. Examples of judicial remedies
that may be fashioned  include judicial  requirements  that the lender undertake
affirmative  and expensive  actions to determine  the causes for 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 judgment
and have  required  lenders to reinstate  loans or recast  payment  schedules to
accommodate borrowers who are suffering from temporary financial disability.  In
some cases, courts have limited the right of lenders to foreclose if the default
under the mortgage  instrument is not monetary,  such as the borrower failing to
adequately  maintain the property or the borrower executing a second mortgage or
deed of trust  affecting  the  property.  In other cases,  some courts have been
faced  with the issue of  whether  federal  or state  constitutional  provisions
reflecting due process concerns for adequate notice require that borrowers under
the deeds of trust  receive  notices in addition  to the  statutorily-prescribed
minimum  requirements.  For the most part,  these  cases have  upheld the notice
provisions as being  reasonable or have found that the sale by a trustee under a
deed of trust  or under a  mortgage  having  a power  of sale  does not  involve
sufficient state action to afford constitutional protections to the borrower.

Environmental Considerations

      A lender may be subject to  unforeseen  environmental  risks when taking a
security  interest  in real or  personal  property.  Property  subject to such a
security  interest  may be  subject  to  federal,  state,  and  local  laws  and
regulations relating to environmental protection.  Such 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;  management  of
electrical or other equipment  containing  polychlorinated  biphenyls  ("PCBs").
Failure  to comply  with such laws and  regulations  may  result in  significant
penalties, including civil and criminal fines. Under the laws of certain states,
environmental  contamination  on a  property  may  give  rise  to a lien  on the
property  to ensure the  availability  and/or  reimbursement  of cleanup  costs.
Generally all subsequent  liens on such property are subordinated to such a lien
and, in some states,  even prior recorded liens are  subordinated  to such liens
("Superliens").  In the latter states, the security interest of the Trustee in a
property that is subject to such Superlien could be adversely affected.

      Under the federal Comprehensive  Environmental Response,  Compensation and
Liability Act, as amended  ("CERCLA"),  and under state law in certain states, a
secured party which takes a deed in lieu of  foreclosure,  purchases a mortgaged
property at a  foreclosure  sale,  operates a mortgaged  property or  undertakes
certain  types of  activities  that may  constitute  management of the mortgaged
property may become  liable in certain  circumstances  for the costs of remedial
action ("Cleanup  Costs") if hazardous wastes or hazardous  substances have been
released or disposed of on the property.  Such 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  aggregate  assets of the property
owner.

      The law is  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 Trust Fund.  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 such 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

                                       82



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 such  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 such 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 such 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  certain  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 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  such  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 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,  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.  This  legislation  more clearly defines the kinds of activities that
would constitute  "participation in management" and that therefore would trigger
liability  for  secured  parties  under  CERCLA.  It  also  identified   certain
activities that ordinarily would not trigger liability,  provided, however, that
such  activities  did not  otherwise  rise to the  level  of  "participation  in
management." The Asset Conservation Act specifically  reverses the Fleet Factors
"capacity to  influence"  standard.  The Asset  Conservation  Act also  provides
additional  protection  against liability in the event of foreclosure.  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 Trust Fund and occasion a loss to the Trust Fund and to  Securityholders  in
certain  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 which 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 prior to the origination of the mortgage loan
or prior to foreclosure or accepting a deed-in-lieu of foreclosure.  Neither the
Depositor nor any Servicer  makes

                                       83



any  representations  or warranties  or assumes any  liability  with respect to:
environmental  conditions of such Mortgaged Property;  the absence,  presence or
effect of hazardous  wastes or hazardous  substances  on, near or emanating from
such Mortgaged  Property;  the impact on  Securityholders  of any  environmental
condition or presence of any substance on or near such  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 such  representation,  warranty or assumption of
liability relative to any such Mortgaged Property.

Due-on-Sale Clauses

      The Mortgage  Loans will  generally  contain  due-on-sale  clauses.  These
clauses  generally  provide that the lender may  accelerate  the maturity of the
loan  if the  mortgagor  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,  with respect to certain loans
the  Garn-St.  Germain  Depository  Institutions  Act  of  1982  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 certain 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 such
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,  certain  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  charge 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

      Some state laws restrict the  imposition  of  Prepayment  Charges and late
fees even when the mortgage 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  mortgage 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.  The "OTS", the agency that
administers  the Parity Act for  unregulated,  non-federally  chartered  housing
creditors,  withdrew its  favorable  Parity Act  regulations  and Chief  Counsel
Opinions that previously authorized  state-chartered housing creditors to charge
Prepayment  Charges  and  late  fees in  certain  circumstances  notwithstanding
contrary state law,  effective  with respect to mortgage loans  originated on or
after July 1, 2003.  However,  the OTS's  ruling does not  retroactively  affect
mortgage loans originated by such entities before July 1, 2003.

Subordinate Financing

      Where a mortgagor  encumbers  mortgaged  property  with one or more junior
liens, the senior lender is subjected to additional  risk.  First, the mortgagor
may have difficulty  servicing and repaying multiple loans. In addition,  if the
junior loan permits recourse to the mortgagor (as junior loans often do) and the
senior  loan does not, a  mortgagor  may be more likely to repay sums due on the
junior loan than those on the senior  loan.  Second,  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
mortgagor 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

                                       84




existing  junior  lender is harmed or the  mortgagor is  additionally  burdened.
Third,  if the  mortgagor  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 shall not apply to certain types of residential first mortgage loans
originated by certain  lenders after March 31, 1980. A similar  federal  statute
was in effect with respect to 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. Certain
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 prior to origination of such mortgage
loans,  any such limitation under such state's usury law would not apply to such
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 such  state  action  will be  eligible  for
inclusion  in a Trust  Fund  unless (i) such  mortgage  loan  provides  for such
interest  rate,  discount  points and charges as are  permitted in such state or
(ii) such  mortgage  loan  provides that the terms thereof shall be construed in
accordance  with the laws of  another  state  under  which such  interest  rate,
discount  points and charges would not be usurious and the  mortgagor's  counsel
has rendered an opinion that such 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  mortgagor  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, thereby permitting the mortgagor 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.  Such
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

                                       85



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,  prior to October  15,  1985,  a law or  constitutional  provision
expressly  rejecting the  applicability of such provisions.  Certain states have
taken such action.

Homeowners Protection Act of 1998

      The  Homeowners  Protection  Act of 1998  ("HOPA")  provides  for  certain
disclosure and termination  requirements for primary mortgage insurance ("PMI").
The  termination  provisions  of HOPA apply only to mortgage  loans  relating to
single-family  primary  residences  originated  on or after July 29, 1999.  Such
termination  provisions  govern when a mortgagor may cancel the  requirement  to
maintain  PMI  and  when  the  requirement  to  maintain  PMI  is  automatically
terminated.  In  general,  voluntary  termination  is  permitted  and  automatic
termination occurs when the principal balance of the mortgage loan is reduced to
80% or  78%,  respectively,  of the  original  property  value.  The  disclosure
requirements  of HOPA vary depending on whether the mortgage loan was originated
before or after July 29, 1999. Such disclosure requirements include notification
of the  circumstances  whereby a  mortgagor  may cancel  PMI,  the date when PMI
automatically  terminates and servicer contact  information.  In addition,  HOPA
provides that no later than 30 days after  cancellation  or  termination of PMI,
the servicer shall provide written  notification that such PMI is terminated and
no further  payments  are due or payable.  Any  servicer,  mortgagee or mortgage
insurer that violates  provisions of HOPA is subject to possible liability which
includes,  but  is  not  limited  to,  actual  damages,  statutory  damages  and
reasonable attorney's fees.

Texas Home Equity Loans

      Generally,   any  "cash-out"   refinance  or  other   non-purchase   money
transaction  (except for  rate/term  refinance  loans and certain  other  narrow
exceptions) secured by a Texas resident's  principal residence is subject to the
provisions set forth in Section  50(a)(6) of Article XVI of the  Constitution of
Texas and its  implementing  statutes  and  regulations  (the "Texas Home Equity
Laws"). The Texas Home Equity Laws provide for certain disclosure  requirements,
caps on allowable fees, required loan closing procedures and other restrictions.
Failure, inadvertent or otherwise, to comply with any requirement may render the
Mortgage Loan  unenforceable  and/or the lien on the Mortgaged Property voidable
unless cured within 60 days after the borrower  provides notice of the defect to
the lender.  Because  mortgage  loans which are subject to the Texas Home Equity
Laws can be foreclosed  only pursuant to court order,  rather than  non-judicial
foreclosure as is available for other types of mortgage  loans in Texas,  delays
and increased  losses may result in connection with  foreclosures of such loans.
If a court were to find that any  requirement  of the Texas Home Equity Laws was
not  complied  with,  the court could  refuse to allow  foreclosure  to proceed,
declare  the lien on the  Mortgaged  Property  to be void,  and/or  require  the
originating  lender or the holder of the note to forfeit  some or all  principal
and interest of the related Mortgage Loan. Title insurance  generally  available
on such Mortgage Loans may exclude  coverage for some of the risks  described in
this paragraph.

Servicemembers Civil Relief Act

      Generally,  under the terms of the  Servicemembers  Civil  Relief Act (the
"Relief Act"), a mortgagor who enters military  service after the origination of
such mortgagor's  Mortgage Loan, including a mortgagor 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,  in excess of 6% per annum during
the period of the mortgagor's  active duty status.  In addition to adjusting the
interest,  the lender must forgive any such  interest in excess of 6%,  unless a
court or administrative  agency orders otherwise upon application of the lender.
Further,  the  Relief  Act  provides  broad  discretion  for a court to modify a
mortgage  loan upon  application  by the  mortgagor.  The Relief Act  applies to
mortgagors  who are members of the U.S.  Armed  Forces and  officers of the U.S.
Public Health  Service or the National  Oceanic and  Atmospheric  Administration
assigned to duty with the military.  The  California  Military and Veterans Code
(the "California  Military Code") provides protection  substantially  similar to
that provided by the Relief Act to California  national  guard members called up
to active service by the Governor,  California  national guard members called up
to active  service by the  President  and  reservists  called to active duty. In
addition,  other states have enacted comparable  legislation which may interfere
with or affect  the  ability  of the  Servicer  to timely  collect  payments  of
principal and interest on, or to foreclose on,  Mortgage  Loans of mortgagors in
such  states  who are active or reserve  members  of the armed  services.  It is
possible that the Relief Act, the California  Military Code or similar state law
could have an effect, for an indeterminate period of time, on the ability of the
Servicer to collect full amounts of interest on certain of the Mortgage Loans in
a  Trust  Fund.  Any  shortfall  in  interest  collections

                                       86



resulting from the  application of the Relief Act, the California  Military Code
or similar state law could result in losses to the holders of the  Securities of
the related Series.  Further, since the Relief Act, the California Military Code
and similar state law impose  limitations  which would impair the ability of the
Servicer to foreclose on an affected Mortgage Loan during the mortgagor's period
of active duty status, in the event that such a Mortgage Loan goes into default,
there may be delays and losses  occasioned  by the inability to realize upon the
Mortgaged Property in a timely fashion.

Forfeiture for Drug, RICO and Money Laundering Violations

      Federal law  provides  that  property  purchased  or improved  with assets
derived from criminal activity or otherwise  tainted,  or used in the commission
of certain offenses, can be seized and ordered forfeited to the United States of
America.  The offenses which can trigger such a seizure and forfeiture  include,
among others,  violations of the Racketeer Influenced and Corrupt  Organizations
Act,  the Bank  Secrecy Act, the  anti-money  laundering  laws and  regulations,
including the USA Patriot Act of 2001 and the regulations issued thereunder,  as
well as the narcotic drug laws. In many  instances,  the United States may seize
the property even before a conviction occurs.

      In the event of a forfeiture proceeding, a lender may be able to establish
its  interest in the  property by proving that (i) its mortgage was executed and
recorded before the commission of the illegal conduct from which the assets used
to purchase or improve the property  were derived or before any other crime upon
which the forfeiture is based, or (ii) the lender,  at the time of the execution
of the mortgage,  "did not know or was reasonably  without cause to believe that
the property was subject to forfeiture." However, there can be no assurance that
such a defense will be successful.

                     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 such 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 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 obligor to repay the loan  evidenced
thereby,  and (b) the grant of a security  interest in the Manufactured  Home to
secure repayment of such loan. Certain 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  applicable
Agreement,  the Servicer will transfer  physical  possession of the Contracts to
the  Trustee or its  custodian  or may retain  possession  of the  Contracts  as
custodian for 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 Company to the Trustee
only if provided in the related prospectus  supplement.  Therefore,  if, through
negligence,  fraud  or  otherwise,  a  subsequent  purchaser  were  able to take
physical  possession of the Contracts  without  notice of such  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 and the District of Columbia.  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

                                       87



authority,  depending on state law. In some nontitle states, perfection pursuant
to the  provisions  of the UCC is  required.  The Asset  Seller may effect  such
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 such notation or delivery, or files the security interest under the wrong
law (for example, under a motor vehicle title statute rather than under the UCC,
in a few  states),  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 certain  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.
In order 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  Home. If, however,  a Manufactured
Home is permanently attached to its site, other parties could obtain an interest
in the  Manufactured  Home which is prior to the  security  interest  originally
retained by the Asset Seller and transferred to the Depositor. With respect to a
Series of Securities and if so described in the related  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 with respect to 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 related 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,  such  assignment is an effective  conveyance of such 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 (or
the filing of a UCC-3  statement),  such assignment of the security  interest in
the Manufactured  Home may not be held effective or such security  interests may
not be perfected and in the absence of such 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 such other originator of the
Contracts)  or a trustee  in  bankruptcy  of the  Asset  Seller  (or such  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 of 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,  such  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.

      In the event  that the owner of a  Manufactured  Home  moves it to a state
other than the state in which such  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 such  relocation  and
thereafter only if and after the owner  re-registers  the  Manufactured  Home in
such state.  If the owner were to relocate a Manufactured  Home to another state
and not re-register the  Manufactured  Home in such state,  and if steps are not
taken to re-perfect the Trustee's

                                       88



security  interest in such 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 such
Manufactured  Home or, in the case of  Manufactured  Homes  registered in states
which 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 which do not require a certificate of title for
registration of a manufactured home, re-registration could defeat perfection. In
the  ordinary  course of  servicing  the  manufactured  housing  contracts,  the
Servicer  takes steps to effect  such  re-perfection  upon  receipt of notice of
re-registration  or information  from the obligor as to  relocation.  Similarly,
when an obligor 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  applicable  Agreement,  the Servicer is
obligated to take such 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
applicable  Agreement that it has no knowledge of any such liens with respect to
any  Manufactured  Home securing  payment on any Contract.  However,  such liens
could arise at any time  during the term of a Contract.  No notice will be given
to the Trustee or Securityholders in the event such a lien arises.

Enforcement of Security Interests in Manufactured Homes

      The  Servicer  on behalf of the  Trustee,  to the extent  required  by the
applicable 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  such  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" (i.e., without breach of the peace)
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
the state,  prior to  commencement  of 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  such a sale.  The law in most states also requires that the debtor be
given  notice of any sale  prior to resale  of the unit so that the  debtor  may
redeem at or before such resale. In the event of such repossession and resale of
a  Manufactured  Home,  the Trustee would be entitled to be paid out of the sale
proceeds  before such 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 such 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.

      Certain other statutory provisions,  including 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 an obligor on a Contract as described
for a mortgagor  on a Mortgage  Loan under  "Certain  Legal  Aspects of Mortgage
Loans--Servicemembers Civil Relief Act."

                                       89



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  which is the seller of goods which gave rise to the  transaction  (and
certain  related lenders and assignees) to transfer such contract free of notice
of claims by the debtor  thereunder.  The effect of this rule is to subject  the
assignee of such a contract to all claims and  defenses  which the debtor  could
assert  against  the  seller of goods.  Liability  under this rule is limited to
amounts paid under a Contract;  however,  the obligor 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 such obligor.  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 such 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 certain cases, the transfer may be made by
a delinquent obligor in order to avoid a repossession proceeding with respect to
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" clause. The Garn-St.  Germain Depositary  Institutions Act of 1982
preempts,  subject to certain exceptions and conditions,  state laws prohibiting
enforcement  of  "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 certain Manufactured Homes.

Applicability of Usury Laws

      Title V provides that,  subject to the following  conditions,  state usury
limitations  shall not apply to any loan  which 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
prior to instituting any action leading to  repossession of or foreclosure  with
respect to the related unit.

      Title V authorized any state to reimpose limitations on interest rates and
finance  charges  by  adopting  before  April  1,  1983 a law or  constitutional
provision which expressly rejects application of the federal law. Fifteen states
adopted such a law prior to 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.

                         FEDERAL INCOME TAX CONSEQUENCES

General

      The following discussion is based on the advice of Cadwalader,  Wickersham
& Taft LLP or Hunton & Williams  LLP,  as to the  anticipated  material  federal
income tax  consequences  of the  purchase,  ownership  and  disposition  of the
Securities  offered  hereunder.  As to any Securities  offered  pursuant hereto,
Cadwalader,  Wickersham  & Taft LLP or Hunton & Williams  LLP is of the  opinion
that the following  discussion,  as  supplemented  by the  discussion  under the
heading "Federal Income Tax Consequences," if any, in the prospectus  supplement
accompanying this prospectus with respect to those Securities, is correct in all
material  respects  as of the  date of such  prospectus  supplement.  Except  as
specifically set forth elsewhere herein,  the opinion set forth in the preceding
sentence  and any  opinions  specifically  set forth in this  discussion  or the
related prospectus  supplement are the only opinions being rendered with respect
to tax  matters  affecting  the  Securities  offered  hereunder  by  Cadwalader,
Wickersham & Taft LLP or Hunton & Williams LLP. The opinion stated above and the
opinions

                                       90



specifically  identified as such in the following  discussion and in the related
prospectus  supplement are the only opinions that Cadwalader,  Wickersham & Taft
LLP or Hunton & Williams  LLP has been asked to render  with  respect to the tax
consequences  of the purchase,  ownership  and  dispositions  of the  Securities
offered  under this  prospectus  and the  related  prospectus  supplement.  This
discussion is directed  solely to  Securityholders  that hold the  Securities 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  and  foreign
investors) may be subject to special rules.  Further,  the  authorities on which
this  discussion,  and the opinion  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  herein,  potential
investors should consider the state and local tax  consequences,  if any, of the
purchase,  ownership and disposition of the Securities. See "State and Other Tax
Consequences."  Securityholders are encouraged to consult their own tax advisors
concerning the federal,  state,  local or other tax  consequences to them of the
purchase, ownership and disposition of the Securities offered hereunder.

      The following  discussion  addresses securities of four general types: (i)
securities  ("REMIC  Securities")  representing  interests in a Trust Fund, or a
portion  thereof,  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, (ii) securities  ("Grantor Trust  Securities")
representing  interests  in a Trust Fund  ("Grantor  Trust Fund") as to which no
such  election  will  be  made,  (iii)  securities  ("Partnership   Securities")
representing  interests  in a Trust Fund  ("Partnership  Trust  Fund")  which is
treated as a partnership  for federal income tax purposes,  and (iv)  securities
("Debt  Securities")  representing  indebtedness of a Partnership Trust Fund for
federal  income tax  purposes.  The  prospectus  supplement  for each  Series of
Securities  will indicate which of the foregoing  treatments  will apply to such
Series  and, if a REMIC  election  (or  elections)  will be made for the related
Trust Fund,  will identify all "regular  interests" and "residual  interests" in
the  REMIC.   For  purposes  of  this  tax  discussion,   (i)  references  to  a
"Securityholder"  or a "holder" are to the beneficial owner of a Security,  (ii)
references  to "REMIC  Pool" are to an entity or  portion  thereof as to which a
REMIC  election will be made and (iii)  references to "Mortgage  Loans"  include
Contracts.  Generally,  no REMIC election will be made with respect to Unsecured
Home Improvement Loans.

      The  following  discussion  is based  in part  upon  the  rules  governing
original issue discount that are set forth in Sections 1271-1273 and 1275 of the
Code and in the Treasury  regulations issued thereunder (the "OID Regulations"),
and in part  upon the  REMIC  Provisions  and the  Treasury  regulations  issued
thereunder  (the "REMIC  Regulations").  The OID  Regulations  do not adequately
address certain issues relevant to, and in some instances  provide that they are
not applicable to, securities such as the Securities.

      Taxable Mortgage Pools

      Corporate  income tax can be imposed on the net income of certain 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 (i)  substantially  all of the assets of the entity  consist of
debt obligations and more than 50% of such  obligations  consist of "real estate
mortgages,"  (ii) such entity is the obligor under debt  obligations with two or
more maturities,  and (iii) under the terms of the debt obligations on which the
entity is the  obligor,  payments on such  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

      With respect to each Series of REMIC Securities,  assuming compliance with
all provisions of the related Pooling and Servicing Agreement, the related Trust
Fund (or each applicable  portion thereof) will qualify as a REMIC and the REMIC
Securities offered with respect thereto will be considered to evidence ownership
of "regular

                                       91



interests"   ("Regular   Securities")   or   "residual   interests"   ("Residual
Securities") in that 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,  may 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  aggregate
adjusted  basis of the  nonqualified  assets  is less  than 1% of the  aggregate
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 thereof and must furnish  applicable tax information to
transferors or agents that violate this  requirement.  The Pooling and Servicing
Agreement  with  respect  to  each  Series  of  REMIC  Securities  will  contain
provisions  meeting these  requirements.  See  "--Taxation of Owners of Residual
Securities--Tax-Related     Restrictions     on     Transfer     of     Residual
Securities--Disqualified Organizations."

      A qualified  mortgage is any obligation that is principally  secured by an
interest in real property and that (i) is either  transferred  to the REMIC Pool
on the Startup Day,  (ii) 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 (iii)  represents an increase in the principal  amount of the  obligation
under  the  terms  of such  obligation  described  in (i) or (ii)  above if such
increase  is  attributable  to an advance  made to the  obligor  pursuant to the
original terms of the obligation,  occurs after the Startup Day of the REMIC and
is  purchased by the REMIC  pursuant to a fixed price  contract in effect on the
Startup Day.  Qualified  mortgages  include whole  mortgage  loans,  such as the
Mortgage Loans, and, generally, 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 Tiered REMICs.  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 (i)
in exchange for any qualified mortgage within a three-month period thereafter or
(ii)  in  exchange  for  a  "defective  obligation"  within  a  two-year  period
thereafter. A "defective obligation" includes (i) a mortgage in default or as to
which default is reasonably foreseeable, (ii) a mortgage as to which a customary
representation  or  warranty  made at the time of transfer to the REMIC Pool has
been breached, (iii) a mortgage that was fraudulently procured by the mortgagor,
and (iv) a mortgage  that was not in fact  principally  secured by real property
(but only if such  mortgage  is  disposed  of within  90 days of  discovery).  A
mortgage loan that is  "defective"  as described in clause (iv) that is not sold
or,  if  within  two  years of the  Startup  Day,  exchanged,  within 90 days of
discovery, ceases to be a qualified mortgage after such 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 (i) 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 certain other contingencies or (ii) to provide a source
of  funding  for  the  purchase  of  additional  mortgage  loans  pursuant  to a
qualifying fixed price or additional draws made by mortgagors under the terms of
loans held by the related  REMIC.  The aggregate fair market of any such reserve
cannot exceed 50% of the aggregate  fair market value of all assets of the REMIC
on the Startup Day. The reserve  fund will be  disqualified  if more than 30% of
the gross  income from the assets in such 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"  as  payments on the  Mortgage  Loans are  received.  Foreclosure
property  is real  property  acquired by the REMIC Pool in  connection  with

                                       92



the default or imminent default of a qualified mortgage and generally may not be
held beyond the close of the third  calendar  year  beginning  after the taxable
year of acquisition unless an extension is granted by the IRS.

      In addition to the  foregoing  requirements,  the various  interests  in a
REMIC Pool also must meet certain requirements.  All of the interests in a REMIC
Pool  must be  either  of the  following:  (i) one or more  Classes  of  regular
interests or (ii) a single class of residual  interests on which  distributions,
if any,  are made pro rata.  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.  Such a
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.  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 with respect to such 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, the Regular Securities of a Series will constitute one
or more Classes of regular interests,  and the Residual  Securities with respect
to that Series will constitute a single Class of residual interests with respect
to 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 such status during any taxable
year,  the Code provides that the entity will not be treated as a REMIC for such
year and thereafter.  In that event, such 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,  no such  regulations have
been issued. Any such relief, moreover, may be accompanied by sanctions, such as
the imposition of a corporate tax on all or a portion of the Trust Fund's income
for the period in which the requirements for such status are not satisfied.  The
Pooling and  Servicing  Agreement  with  respect to each REMIC Pool will include
provisions  designed to maintain  the Trust  Fund's  status as a REMIC under the
REMIC  Provisions.  It is not anticipated that the status of any Trust Fund as a
REMIC will be terminated.

      Characterization of Investments in REMIC Securities

      In general,  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 such Securities 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.
If the assets of the REMIC Pool include  Buydown  Mortgage Loans, it is possible
that the  percentage  of such  assets  constituting  "loans . . .  secured by an
interest in real property which is . . . residential real property" for purposes
of Code Section 7701(a)(19)(C)(v) may be required to be reduced by the amount of
the related  funds paid  thereon  (the  "Buydown  Funds").  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 such  Securities  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 therein.  The determination as
to the percentage of the REMIC Pool's assets that constitute assets described in
the  foregoing  sections of the Code will be made with respect to each  calendar
quarter based on the average  adjusted basis of each category of the assets held
by the REMIC Pool  during such  calendar  quarter.  The REMIC will report  those
determinations  to  Securityholders  in the manner and at the times  required by
applicable Treasury regulations.

      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

                                       93



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  such 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 certain Series of REMIC Securities, two or more separate elections may
be made to  treat  designated  portions  of the  related  Trust  Fund as  REMICs
("Tiered REMICs") for federal income tax purposes. Upon the issuance of any such
Series  of REMIC  Securities,  Cadwalader,  Wickersham  & Taft  LLP or  Hunton &
Williams  LLP will deliver its opinion  generally  to the effect that,  assuming
compliance with all provisions of the related  Pooling and Servicing  Agreement,
the Tiered REMICs will each qualify as a REMIC and the REMIC  Securities  issued
by the  Tiered  REMICs  will be  considered  to  evidence  ownership  of Regular
Securities or Residual Securities 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 such  Securities  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

      General

      In general,  interest,  original issue discount,  and market discount on a
Regular  Security will be treated as ordinary  income to a holder of the Regular
Security (the  "Regular  Securityholder"),  and principal  payments 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 such
Regular Securityholder.

      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 such income. The following discussion is
based in part on OID  Regulations  issued under Code  Sections 1271 through 1273
and 1275 and in part on the provisions of the 1986 Act. Regular  Securityholders
should be aware,  however,  that the OID  Regulations do not adequately  address
certain  issues  relevant  to  prepayable   securities,   such  as  the  Regular
Securities. To the extent such issues are not addressed in such regulations, the
Depositor intends to apply the methodology described in the Conference Committee
Report to the 1986 Act. No assurance  can be provided that the IRS 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  IRS to  apply  or  depart  from  the OID  Regulations  where  necessary  or
appropriate  to  ensure a  reasonable  tax  result  in  light of the  applicable
statutory provisions. A tax result will not be considered unreasonable under the
anti-abuse rule in the absence of a 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  therein and the appropriate  method for reporting
interest and original issue discount with respect to the Regular Securities.

      Each Regular  Security  (except to the extent described below with respect
to a Regular Security on which principal is distributed in a single  installment
or by lots of specified  principal  amounts upon the request of a Securityholder
or by random  lot (a  "Non-Pro  Rata  Security"))  will be  treated  as a single
installment  obligation for

                                       94



purposes of  determining  the original  issue  discount  includable 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 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  such  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  prior to the issue date of the  Regular  Security,  unless  the  Regular
Securityholder  elects on its federal  income tax return to exclude  such 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 such 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 such  interest  payments are  unconditionally
payable at  intervals  of one year or less during the entire term of the Regular
Security.  Because  there  is no  penalty  or  default  remedy  in the  case  of
nonpayment of interest with respect to 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 applicable prospectus  supplement,  because the underlying Mortgage Loans
provide for remedies in the event of default, it is anticipated that the Trustee
will treat interest with respect to the Regular  Securities as qualified  stated
interest.  Distributions of interest on an Accrual Security, or on other Regular
Securities  with  respect  to which  deferred  interest  will  accrue,  will not
constitute qualified stated interest,  in which case the stated redemption price
at maturity of such Regular Securities includes all distributions of interest as
well as principal  thereon.  Likewise,  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 such 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 such
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 with respect to a Series of Regular Securities will be set
forth in the applicable prospectus supplement.  Holders generally must report de
minimis original issue discount pro rata as principal payments are received, and
such  income will 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  discount and
market  premium,  under the constant yield method.  See "--Election to Treat All
Interest Under the Constant Yield Method."

      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.  With
respect to 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
(i) 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

                                       95



Regular  Security's stated redemption price at maturity,  over (ii) 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 (i) the  yield  to  maturity  of the  Regular
Security at the issue date, (ii) events (including actual prepayments) that have
occurred  prior to the end of the  accrual  period,  and  (iii)  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  aggregate  amount of original  issue  discount with
respect to 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 such
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. With respect to 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 with respect to a Series of Regular Securities
can result in both a change in the priority of principal  payments  with respect
to certain  Classes of Regular  Securities and either an increase or decrease in
the daily  portions of original  issue  discount  with  respect to such  Regular
Securities.

      In the case of a Non-Pro Rata Security, it is anticipated that the Trustee
will determine the yield to maturity of such Security based upon the anticipated
payment characteristics of the Class as a whole under the Prepayment Assumption.
In general,  the original issue discount  accruing on each Non-Pro Rata Security
in a full accrual  period  would be its  allocable  share of the original  issue
discount with respect to the entire Class,  as determined in accordance with the
preceding paragraph. However, in the case of a distribution in retirement of the
entire unpaid principal balance of any Non-Pro Rata Security (or portion of such
unpaid principal  balance),  (a) the remaining unaccrued original issue discount
allocable to such  Security (or to such portion) will accrue at the time of such
distribution,  and (b) the accrual of original issue discount  allocable to each
remaining  Security of such Class will be adjusted by reducing the present value
of the  remaining  payments on such Class and the  adjusted  issue price of such
Class to the extent  attributable to the portion of the unpaid principal balance
thereof  that  was  distributed.  The  Depositor  believes  that  the  foregoing
treatment  is  consistent  with  the  "pro  rata  prepayment"  rules  of the OID
Regulations,  but with the rate of accrual of original issue discount determined
based on the  Prepayment  Assumption  for the  Class as a whole.  Investors  are
advised to consult their tax advisors as to this treatment.

      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 such
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,  such  a  subsequent  purchaser  may  elect  to  treat  all  such
acquisition  premium under the constant yield method,  as described  below under
the heading "--Election to Treat All Interest Under the Constant Yield Method."

      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 variable rate if,
generally, (i) the issue price does not exceed the original principal balance by
more than a specified  amount and (ii) 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) a 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

                                       96



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 that 0.65 but not more than
1.35, increased or decreased by a fixed rate. Such 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 such information is not (i) within the control of the
issuer or a related party or (ii) unique to the circumstances of the issuer or a
related party. 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 cost of newly borrowed funds; 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 variable rate under the foregoing rules, for example,  a Class that bears
different rates at different times during the period it is outstanding such that
it is  considered  significantly  "front-loaded"  or  "back-loaded"  within  the
meaning  of the  OID  Regulations.  It is  possible  that  such 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  with respect to Regular
Securities  apply the same principles as the OID  Regulations,  such regulations
may lead to different  timing of income  inclusion  that would be the case under
the OID Regulations.  Furthermore,  application of such principles could lead to
the  characterization  of  gain  on the  sale  of  contingent  interest  Regular
Securities  as ordinary  income.  Investors  should  consult  their tax advisors
regarding the  appropriate  treatment of any Regular  Security that does not pay
interest at a fixed rate or variable rate as described in this paragraph.

      Under the REMIC Regulations,  a Regular Security (i) bearing interest at a
rate that qualifies as a variable rate under the OID Regulations that is tied to
current  values of a variable rate (or the highest,  lowest or average of two or
more variable rates,  including a rate based on the average cost of funds of one
or more financial  institutions),  or a positive or negative  multiple of such a
rate (plus or minus a specified  number of basis points),  or that  represents a
weighted average of rates on some or all of the Mortgage Loans, including such a
rate that is subject to one or more caps or floors,  or (ii) bearing one or more
such variable rates for one or more periods,  or one or more fixed rates for one
or more periods,  and a different variable rate or fixed rate for other periods,
qualifies as a regular interest in a REMIC. Accordingly,  it is anticipated that
the Trustee will treat  Regular  Securities  that  qualify as regular  interests
under this rule in the same manner as  obligations  bearing a variable  rate for
original issue discount reporting purposes.

      The amount of original issue  discount with respect to a Regular  Security
bearing a variable  rate of interest will accrue in the manner  described  above
under "Original Issue  Discount," with the yield to maturity and future payments
on such 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.  Unless  required  otherwise by applicable  final
regulations,  it is  anticipated  that the  Trustee  will  treat  such  variable
interest  as  qualified  stated  interest,  other than  variable  interest on an
interest-only  or  super-premium  Class,  which will be treated as non-qualified
stated interest includable in the stated redemption price at maturity.  Ordinary
income reportable for any period will be adjusted based on subsequent changes in
the applicable interest rate index.

      Although unclear under the OID Regulations,  unless required  otherwise by
applicable  final  regulations,  the Seller intends to treat Regular  Securities
bearing an interest rate that is a weighted average of the net interest rates on
Mortgage Loans as having qualified  stated  interest,  except to the extent that
initial "teaser" rates cause sufficiently  "back-loaded" interest to create more
than de minimis  original issue discount.  The yield on such Regular  Securities
for purposes of accruing  original issue  discount will be a hypothetical  fixed
rate based on the fixed rates,  in the case of fixed-rate  Mortgage  Loans,  and
initial  "teaser  rates"  followed  by  fully  indexed  rates,  in the  case  of
adjustable-rate  Mortgage Loans. In the case of adjustable-rate  Mortgage Loans,
the applicable index used to compute interest on the Mortgage Loans in effect on
the  pricing  date (or  possibly  the issue date) will be deemed to be in effect
beginning with the period in which the first weighted  average  adjustment  date
occurring after the issue date occurs.  Adjustments will be made in each accrual
period either  increasing or decreasing the amount of ordinary income reportable
to reflect the actual Pass-Through Rate on the Regular Securities.

                                       97



      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  (i)  is  exceeded  by the  remaining
outstanding principal payments and interest payments other than qualified stated
interest  payments due on a Regular  Security,  or (ii) in the case of a Regular
Security having original issue discount, is exceeded by the adjusted issue price
of such Regular Security at the time of purchase.  Such purchaser generally will
be  required  to  recognize  ordinary  income to the  extent of  accrued  market
discount on such  Regular  Security as  distributions  includable  in the stated
redemption  price at maturity  thereof are received,  in an amount not exceeding
any such  distribution.  Such  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
such regulations are issued, such market discount would accrue either (i) on the
basis of a  constant  interest  rate,  or (ii) in the ratio of  stated  interest
allocable to the relevant period to the sum of the interest for such period plus
the remaining interest as of the end of such 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 such period plus the remaining  original issue discount as
of the end of such period.  Such  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.  Such 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  thereon.  The  deferred  portion of such  interest
expense  in any  taxable  year  generally  will not exceed  the  accrued  market
discount on the  Regular  Security  for such year.  Any such  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 all market  discount  instruments
acquired by such 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 such election may be deemed to be made. A person who purchases a
Regular Security at a price lower than the remaining  amounts  includable 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 with respect to a Regular  Security will be considered to
be zero if such  market  discount  is less than  0.25% of the  remaining  stated
redemption  price at maturity  of such  Regular  Security  (or, in the case of a
Regular  Security having  original issue  discount,  the adjusted issue price of
such  Regular  Security)  multiplied  by the  weighted  average  maturity of the
Regular  Security  (determined as described  above in the third  paragraph under
"--Original  Issue Discount")  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.

      Under  provisions of the OID  Regulations  relating to contingent  payment
obligations,  a secondary  purchaser of a Regular  Security that has "contingent
interest"  at a  discount  generally  would  continue  to  accrue  interest  and
determine  adjustments on the Regular  Security based on the original  projected
payment  schedule  devised by the issuer of the  Security.  The holder of such a
Regular Security would be required,  however, to allocate the difference between
the  adjusted  issue price of the Regular  Security and its basis in the Regular
Security as positive  adjustments  to the accruals or projected  payments on the
Regular  Security  over the remaining  term of the Regular  Security in a manner
that is reasonable (e.g., based on a constant yield to maturity).

      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 given Class of Regular Securities.  Prospective investors in
Regular   Securities  should  consult  their  own  tax  advisors  regarding  the
application of the market  discount rules to the Regular  Securities.  Investors
should also consult Revenue  Procedure 92-67 concerning the elections to include
market  discount in income  currently and to accrue market discount on the basis
of the constant yield method.

                                       98



      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 such Regular Security as a "capital
asset" within the meaning of Code Section 1221, the Regular  Securityholder  may
elect under Code  Section 171 to amortize  such premium  under a constant  yield
method that reflects  compounding  based on the interval between payments on the
Regular  Security.  Such  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 IRS. Final Treasury  regulations have been issued with respect
to  amortizable  bond  premiums  which do not by their terms apply to prepayable
debt  instruments  such  as the  Regular  Securities.  However,  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 such 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
deduction.  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.

      Amortizable premium on a Regular Security that is subject to redemption at
the  option  of the  issuer  generally  must  be  amortized  as if the  optional
redemption price and date were the Security's principal amount and maturity date
if doing so would result in a smaller amount of premium  amortization during the
period  ending with the optional  redemption  date.  Thus, a holder of a Regular
Security would not be able to amortize any premium on a Regular Security that is
subject  to  optional  redemption  at a  price  equal  to or  greater  than  the
Securityholder's  acquisition  price  unless  and  until the  redemption  option
expires.  A Regular  Security  subject to redemption at the option of the issuer
described in the  preceding  sentence  will be treated as having  matured on the
redemption  date for the  redemption  price and then as having been  reissued on
that date for that price.  Any premium  remaining on the Regular Security at the
time of the deemed reissuance will be amortized on the basis of (i) the original
principal  amount and maturity date or (ii) the price and date of any succeeding
optional redemption, under the principles described above.

      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 such an election,  (i) "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 (ii) the debt instrument is treated 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 such an election on an instrument by instrument  basis or for
a Class or group of debt  instruments.  However,  if the  holder  makes  such an
election with respect to a debt instrument with amortizable bond premium or with
market  discount,  the holder is deemed to have made  elections to amortize bond
premium or to report market  discount  income  currently as it accrues under the
constant  yield  method,  respectively,  for all  premium  bonds  held or 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 IRS.  Investors should consult their own tax advisors  regarding
the advisability of making such an election.

      Treatment of Losses

      Regular  Securityholders will be required to report income with respect to
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 such
losses  are  uncollectable.  Accordingly,  the  holder  of a  Regular  Security,
particularly a Subordinated Security, may have income, or may incur

                                       99



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 uncollectable,  the IRS 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.  Under Code Section 166, 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
such loss with respect to principal sustained during the taxable year on account
of any such 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 such  Regular  Securities  becoming  wholly
worthless.  Although  the  matter is not free  from  doubt,  such  non-corporate
Regular  Securityholders  should be allowed a bad debt deduction at such time as
the principal  balance of such Regular  Securities is reduced to reflect  losses
resulting from any liquidated  Mortgage Loans. The IRS, however,  could take the
position  that  non-corporate  holders  will be allowed a bad debt  deduction to
reflect  such losses only after all the  Mortgage  Loans  remaining in the Trust
Fund have been liquidated or the applicable Class of Regular Securities has been
otherwise  retired.  The IRS  could  also  assert  that  losses  on the  Regular
Securities  are  deductible  based on some  other  method  that may  defer  such
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 which would be deductible only against future
positive  original issue  discount or otherwise  upon  termination of the Class.
Regular  Securityholders  are urged to consult their own tax advisors  regarding
the appropriate timing,  amount and character of any loss sustained with respect
to such Regular  Securities.  While losses  attributable to interest  previously
reported as income should be deductible as ordinary losses by both corporate and
non-corporate holders, the IRS 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 are applicable to banks
and thrift institutions,  including rules regarding reserves for bad debts. Such
taxpayers are advised to consult  their tax advisors  regarding the treatment of
losses on Regular Securities.

      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 with respect
to 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 with respect to 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). Such gain will be
treated  as  ordinary  income  (i) 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 with respect to any prior  disposition of
property  that  was  held as part of  such  transaction,  (ii) in the  case of a
non-corporate  taxpayer,  to the extent such 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 (iii) to the extent that such gain does not exceed the
excess,  if any, of (a) the amount that would have been  includable in the gross
income  of the  holder if its yield on such  Regular  Security  were 110% of the
applicable  Federal  rate as of the date of  purchase,  over (b) the  amount  of
income  actually  includable  in the gross income of such holder with respect to
such Regular Security.  In addition,  gain or loss recognized from the sale of a
Regular  Security  by certain  banks or thrift  institutions  will be treated as
ordinary income or loss pursuant to Code Section 582(c). Long-term capital gains
of certain  noncorporate  taxpayers generally are subject to a lower maximum tax
rate than  ordinary  income or short-term  capital  gains of such

                                       100



taxpayers for property held for more than one year.  Currently,  the maximum tax
rate for  corporations  is the same with  respect  to both  ordinary  income and
capital gains.

      Taxation of Owners of Residual Securities

      Taxation of REMIC Income

      Generally,  the "daily  portions" of REMIC taxable income or net loss will
be  includable as ordinary  income or loss in  determining  the federal  taxable
income of holders of Residual 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 such
quarter and by  allocating  such daily  portion  among the  Residual  Holders in
proportion to their respective holdings of Residual Securities in the REMIC Pool
on such 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 (i) the limitations on deductibility of investment  interest expense
and expenses for the production of income do not apply,  (ii) all bad loans will
be  deductible  as  business  bad  debts,   and  (iii)  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.  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  Securities 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 with respect to 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.  In the event that an interest in the Mortgage  Loans is acquired by
the REMIC Pool at a discount, and one or more of such 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 (ii) the discount on the
Mortgage  Loans which is includable  in income may exceed the deduction  allowed
upon such  distributions on those Regular Securities on account of any unaccrued
original issue discount relating to those 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 such  Classes  are not issued  with  substantial
discount or are issued at a premium.  If taxable income  attributable  to such a
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 such a 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 with respect to any
given  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 such mismatching or unrelated  deductions against which
to offset such income,  subject to the discussion of "excess  inclusions"  below
under "--Limitations on Offset or Exemption of REMIC Income." The timing of such
mismatching of income and  deductions  described in this  paragraph,  if present
with respect to a Series of  Securities,  may have a significant  adverse effect
upon a Residual Holder's after-tax rate of return.

      A  portion  of the  income of a  Residual  Securityholder  may be  treated
unfavorably  in three  contexts:  (i) it may not be  offset  by  current  or net
operating loss deductions; (ii) it will be considered unrelated business taxable
income to tax-exempt  entities;  and (iii) it is ineligible for any statutory or
treaty  reduction in the 30%  withholding  tax otherwise  available to a foreign
Residual  Securityholder.  See  "--Limitations  on Offset or  Exemption of REMIC

                                       101



Income" below. In addition,  a Residual  Holder's  taxable income during certain
periods  may exceed the  income  reflected  by such  Residual  Holders  for such
periods in accordance with generally accepted accounting  principles.  Investors
should consult their own  accountants  concerning  the  accounting  treatment of
their investment in Residual Securities.

      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 such  Residual  Security.  Such  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  such loss was  disallowed  and may be used by such  Residual
Holder only to offset any income generated by the same REMIC Pool.

      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,  the taxable income will not include cash received
by the REMIC Pool that  represents  a recovery of the REMIC  Pool's basis in its
assets.  Although the law is unclear in certain respects, such recovery of basis
by the REMIC Pool will have the effect of amortization of the issue price of the
Residual   Securities  over  their  life.  However,  in  view  of  the  possible
acceleration of the income of Residual Holders described above under "--Taxation
of REMIC  Income," the period of time over which such issue price is effectively
amortized may be longer than the economic life of the Residual Securities.

      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 such a  residual
interest as zero rather than such  negative  amount for purposes of  determining
the REMIC Pool's basis in its assets.  Regulations  have been issued  addressing
the federal income tax treatment of "inducement fees" received by transferees of
noneconomic  residual  interests.  The regulations require inducement fees to be
included  in income  over a period  reasonably  related to the period in which a
Residual  Security is expected  to  generate  taxable  income or net loss to its
holder.  Under two safe harbor  methods,  inducement  fees are  permitted  to be
included  in income:  (i) in the same  amounts and over the same period that the
holder uses for financial reporting  purposes,  provided that such period is not
shorter than the period the related REMIC is expected to generate taxable income
or (ii) ratably over the remaining  anticipated weighted average life of all the
regular and residual interests issued by the related REMIC,  determined based on
actual  distributions  projected as remaining to be made on such interests under
the applicable  prepayment  assumption.  If a Residual Holder sells or otherwise
disposes of the residual  interest,  any unrecognized  portion of the inducement
fee is required to be taken into account at the time of the sale or disposition.

      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 Pool's basis in the Mortgage Loans, the
Residual  Holder will not recover a portion of such basis until  termination  of
the  REMIC  Pool  unless  future  Treasury   regulations  provide  for  periodic
adjustments to the REMIC income otherwise  reportable by such 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.

      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  with  respect  to 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.

                                       102



      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  "--Taxation of
Owners of Regular Securities--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 such
Mortgage Loans is exceeded by their unpaid principal balances.  The REMIC Pool's
basis in such Mortgage  Loans is generally the fair market value of the Mortgage
Loans  immediately  after the  transfer  thereof  to the REMIC  Pool.  The REMIC
Regulations  provide  that  such  basis is equal in the  aggregate  to the issue
prices of all  regular and  residual  interests  in the REMIC Pool.  The accrued
portion of such market  discount  would be  recognized  currently  as an item of
ordinary income in a manner similar to original issue discount.  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 thereof, the REMIC Pool will be considered
to have acquired  such  Mortgage  Loans at a premium equal to the amount of such
excess.  As stated above,  the REMIC Pool's basis in Mortgage  Loans is the fair
market value of the Mortgage  Loans,  based on the aggregate of the issue prices
of the regular and residual  interests in the REMIC Pool  immediately  after the
transfer  thereof 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
mortgagors on the Mortgage  Loans are expected to be  individuals,  Code Section
171 will not be available for premium on Mortgage  Loans  originated on or prior
to September  27,  1985.  Premium  with  respect to such  Mortgage  Loans may be
deductible  in accordance  with a reasonable  method  regularly  employed by the
holder thereof. The allocation of such premium pro rata among principal payments
should be considered a reasonable method;  however,  the IRS may argue that such
premium  should be  allocated in a different  manner,  such as  allocating  such
premium entirely to the final payment of principal.

      Limitations on Offset or Exemption of REMIC Income

      A portion (or all) of the REMIC taxable  income  includable 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 such  quarterly  period of (i) 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 (ii) the adjusted issue price of such Residual  Security
at the beginning of such 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 such daily  accruals of REMIC income
described  in  this  paragraph  for  all  prior   quarters,   decreased  by  any
distributions made with respect to such Residual Security prior to the beginning
of such quarterly period.  Accordingly,  the portion of the REMIC Pool's taxable
income  that will be treated as excess  inclusions  will be a larger  portion of
such income as the adjusted issue price of the Residual Securities diminishes.

      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 such 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 such
Residual  Holder for purposes of Code Section  511. In addition,  REMIC  taxable
income is subject to 30% withholding tax with respect to certain 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

                                       103



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 certain  persons who are not U.S.
Persons.

      There are three rules for determining  the effect of excess  inclusions on
the alternative minimum taxable income of a Residual Holder. First,  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. Second, a Residual Holder's alternative minimum taxable income for a
taxable year cannot be less than the excess  inclusions for the year. Third, the
amount of any  alternative  minimum tax net  operating  loss  deduction  must be
computed without regard to any excess inclusions.

      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 (i) the
present value of the total  anticipated  excess  inclusions with respect to such
Residual  Security for periods after the transfer and (ii) 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 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.
Such 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.
Such a tax  generally  would  be  imposed  on  the  transferor  of the  Residual
Security,  except  that where such  transfer  is through an agent  (including  a
broker,  nominee, or other middleman) for a Disqualified  Organization,  the tax
would  instead be imposed on such agent.  However,  a  transferor  of a Residual
Security  would in no event be liable for such tax with respect to 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 such affidavit is
false.  The tax also may be waived by the IRS if the  Disqualified  Organization
promptly disposes of the Residual Security and the transferor pays income tax at
the highest  corporate rate on the excess  inclusion for the period the Residual
Security is actually held by the Disqualified Organization.

      In  addition,  if a  Pass-Through  Entity  (as  defined  below) has excess
inclusion income with respect to a Residual Security during a taxable year and a
Disqualified  Organization  is the record  holder of an equity  interest in such
entity,  then a tax is imposed on such  entity  equal to the  product of (i) the
amount  of  excess  inclusions  that  are  allocable  to  the  interest  in  the
Pass-Through Entity during the period such interest is held by such Disqualified
Organization,  and (ii) the highest marginal federal  corporate income tax rate.
Such 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
such tax if it has received an affidavit  from such record holder that it is not
a Disqualified  Organization  or stating such holder's  taxpayer  identification
number and,  during the period such person is the record  holder of the Residual
Security,  the  Pass-Through  Entity  does not have actual  knowledge  that such
affidavit is false.

      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(c) of the Code. An exception to this tax, otherwise  available to a
Pass-Through  Entity that is furnished  certain  affidavits by record holders of
interests in the entity and that does not know such affidavits are false, is not
available to an electing large partnership.

      For these  purposes,  (i)  "Disqualified  Organization"  means the  United
States, any state or political subdivision thereof, any foreign government,  any
international  organization,  any  agency  or  instrumentality  of  any  of  the
foregoing  (provided,  that such term does not include an instrumentality if all
of its activities are subject to tax and a majority of its board of directors in
not selected by any such  governmental  entity),  any  cooperative  organization
furnishing  electric energy or providing  telephone  service or 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 531) that is exempt from
taxation  under the Code  unless  such  organization  is  subject  to the tax on
unrelated  business  income  imposed by Code  Section  511,  (ii)  "Pass-Through
Entity" means any regulated  investment  company,  real estate investment trust,
common  trust  fund,  partnership,  trust or  estate  and  certain  corporations
operating  on a  cooperative

                                       104



basis. 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
such interest, be treated as a Pass-Through Entity, and (iii) an "electing large
partnership"  means any  partnership  having  more than 100  members  during the
preceding  tax year (other  than  certain  service  partnerships  and  commodity
pools), which elect to apply simplified reporting provisions under the Code.

      The Pooling and Servicing  Agreement with respect to a Series will provide
that no legal or beneficial  interest in a Residual  Security may be transferred
or registered unless (i) the proposed transferee furnished to the transferor and
the  Trustee an  affidavit  providing  its  taxpayer  identification  number and
stating that such  transferee is the beneficial  owner of the Residual  Security
and is not a  Disqualified  Organization  and is not  purchasing  such  Residual
Security on behalf of a Disqualified Organization (i.e., as a broker, nominee or
middleman  thereof) and (ii) the  transferor  provides a statement in writing to
the  Trustee  that it has no  actual  knowledge  that such  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
with respect to a Series will bear a legend  referring to such  restrictions  on
transfer, and each Residual Holder will be deemed to have agreed, as a condition
of ownership  thereof,  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 IRS and to the requesting  party
within 60 days of the request, and the Depositor or the Trustee may charge a fee
for computing and providing such information.

      Noneconomic  Residual  Interests.  The REMIC  Regulations  would disregard
certain  transfers of Residual  Securities,  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 for 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,  (i) 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 (ii) 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. Under the REMIC  Regulations,  as amended on
July 19, 2002, a safe harbor is provided if (i) 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,  (ii) 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 (iii) the transferee  represents to the  transferor  that it will
not cause  income from the  Residual  Security to be  attributable  to a foreign
permanent  establishment  or fixed base  (within  the  meaning of an  applicable
income tax  treaty) of the  transferee  or any other  person.  The  Pooling  and
Servicing Agreement with respect to each Series of Certificates will require the
transferee  of a Residual  Security to certify to the  matters in the  preceding
sentence  as  part  of  the   affidavit   described   above  under  the  heading
"Disqualified Organizations."

      In addition to the three  conditions set forth above for the transferor of
a noneconomic  residual  interest to be presumed not to have  knowledge that the
transferee  would be  unwilling  or  unable to pay taxes due on its share of the
taxable income of the REMIC,  the REMIC  Regulations  contain a fourth condition
for the transferor to be presumed to lack such knowledge.  This fourth condition
requires that one of the two following tests be satisfied: Either

                                       105



            (a)   the  present  value  of  the   anticipated   tax   liabilities
      associated with holding the noneconomic  residual  interest not exceed the
      sum of:

      (i)   the present value of any  consideration  given to the  transferee to
acquire the interest;

      (ii)  the  present  value  of the  expected  future  distributions  on the
interest; and

      (iii) the present value of the  anticipated  tax savings  associated  with
holding the interest as the REMIC generates losses.

      For purposes of these  computations,  the transferee is assumed to pay tax
at the  highest  corporate  rate of tax  specified  in the Code or,  in  certain
circumstances,  the  alternative  minimum  tax  rate.  Further,  present  values
generally  are computed  using a discount rate equal to the  short-term  Federal
rate set forth in Section  1274(d) of the Code for the month of the transfer and
the compounding period used by the transferee; or

            (b)   (i) the transferee must be a domestic "C"  corporation  (other
      than a corporation exempt from taxation or a regulated  investment company
      or real estate  investment trust) that meets certain asset tests; (ii) the
      transferee  must  agree in writing  that any  subsequent  transfer  of the
      residual  interest would be to an eligible "C"  corporation and would meet
      the  requirements  for a safe  harbor  transfer;  and  (iii) the facts and
      circumstances  known  to the  transferor  on or  before  the  date  of the
      transfer  must not  reasonably  indicate  that the taxes  associated  with
      ownership of the residual interest will not be paid by the transferee.

      The Pooling and Servicing Agreement will not require that transfers of the
Residual  Securities meet the fourth  requirement  above, and thus meet the safe
harbor.  Persons  considering  the  purchase of the Residual  Securities  should
consult their advisors  regarding the advisability of meeting the safe harbor in
any transfer of the Residual Securities.

      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 appears intended to apply
to a  transferee  who is not a "U.S.  Person"  (as defined  below),  unless such
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, (i) the future value of
expected  distributions equals at least 30% of the anticipated excess inclusions
after  the  transfer,  and  (ii)  the  transferor  reasonably  expects  that the
transferee will receive sufficient distributions from the REMIC Pool at or after
the time at which the excess  inclusions accrue and prior to the end of the next
succeeding  taxable year for the  accumulated  withholding  tax  liability to be
paid.  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  Securities  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  such a  transfer  may be made.  The term "U.S.
Person"  means a citizens or resident of the United  States,  a  corporation  or
partnership  (unless,  in the case of a partnership,  Treasury  regulations  are
adopted that provide otherwise) created or organized in or under the laws of the
United  States,  any state  thereof or the  District of  Columbia,  including an
entity treated as a corporation or partnership  for federal income tax purposes,
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 such trust and one or more such
U.S.  Persons have the  authority to control all  substantial  decisions of such
trust (or, to the extent provided in applicable  Treasury  regulations,  certain
trusts in existence on August 20, 1996 which are eligible to elect to be treated
as U.S. Persons).

                                       106



      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 such Residual Holder in such Residual Security
at the time of the sale or exchange. In addition to reporting the taxable income
of the REMIC Pool, a Residual Holder will have taxable income to the extent that
any cash  distribution  to it from the REMIC Pool exceeds such adjusted basis on
that  Distribution  Date.  Such  income will be treated as gain from the sale or
exchange of the  Residual  Holder's  Residual  Security,  in which case,  if the
Residual  Holder has an adjusted basis in its Residual  Security  remaining when
its  interest  in the  REMIC  Pool  terminates,  and if it holds  such  Residual
Security as a capital  asset under Code Section 1221,  then it will  recognize a
capital loss at that time in the amount of such remaining adjusted basis.

      Any gain on the sale of a Residual  Security  will be treated as  ordinary
income (i) 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 with respect to any prior  disposition of property that was held
as a part of such  transaction or (ii) in the case of a non-corporate  taxpayer,
to the extent such 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
certain banks or thrift  institutions will be treated as ordinary income or loss
pursuant to Code Section 582(c).

      The Conference  Committee Report to the 1986 Act provides that,  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 such 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.

      Mark to Market Regulations

      The IRS has issued final  regulations  (the "Mark to Market  Regulations")
under Code Section 475 relating to the requirement that a securities dealer mark
to market securities held for sale to customers. This mark-to-market requirement
applies to all securities of a dealer,  except to the extent that the dealer has
specifically  identified a security as held for  investment.  The Mark to Market
Regulations  provide that,  for purposes of this mark to market  requirement,  a
Residual  Security  is not  treated as a security  and thus may not be marked to
market.

      Taxes That May Be Imposed on the REMIC Pool

      Prohibited Transactions

      Income  from  certain  transaction  by the REMIC Pool,  called  prohibited
transactions,  will not be part of the  calculation of income or loss includable
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  (i)  the  disposition  of a  qualified  mortgages  other  than  for (a)
substitution  within two years of the Startup Day for a defective  (including  a
defaulted)  obligation  (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,  (ii) the  receipt of income  from
assets that are not the type of mortgages or investments  that the REMIC Pool is
permitted to hold, (iii) the receipt of compensation  for services,  or (iv) the
receipt of gain from disposition of cash flow investments other than pursuant to
a qualified  liquidation.  Notwithstanding  (i) and (iv), 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  (generally,  an optional
termination to save administrative costs when no more than a small percentage of
the  Securities  is  outstanding).  The  REMIC  Regulations  indicate  that  the
modification  of a Mortgage Loan  generally will not be treated as a disposition
if  it  is  occasioned  by a  default  or  reasonably  foreseeable  default,  an
assumption   of  the

                                       107



Mortgage Loan, the waiver of a due-on-sale or due-on-encumbrance  clause, or the
conversion  of an  interest  rate by a  mortgagor  pursuant  to the  terms  of a
convertible adjustable rate Mortgage Loan.

      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 (i) during the
three months following the Startup Day, (ii) made to a qualified reserve fund by
a Residual Holder, (iii) in the nature of a guarantee, (iv) made to facilitate a
qualified  liquidation  or clean-up  call,  and (v) 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.

      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  deed  in  lieu  of  foreclosure  would  be  treated  as
"foreclosure  property" for a period ending with the close of the third calendar
year  beginning  after the year in which the REMIC Pool acquires such  property,
with a possible extension.  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  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.

      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 such  adoption  is deemed to
occur,  and sells all of its assets  (other  than cash)  within a 90-day  period
beginning  on such 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.

      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 such 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 IRS 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,  with  respect to 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 such  Residual  Holder,  such  Residual  Holder or such
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  certain
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 such proceedings in appropriate circumstances.

      Limitations on Deduction of Certain Expenses

      An  investor  who is an  individual,  estate,  or trust will be subject to
limitation with respect to certain itemized deductions described in Code Section
67, to the extent that such itemized deductions, in the aggregate, do not exceed
2% of the  investor's  adjusted  gross  income.  In  addition,  Code  Section 68
provides that itemized

                                       108



deductions otherwise allowable for a taxable year of an individual taxpayer will
be reduced by the lesser of (i) 3% of the  excess,  if any,  of  adjusted  gross
income over a statutory  threshold  amount or (ii) 80% of the amount of itemized
deductions  otherwise  allowable for such year. These limitations will be phased
out and  eliminated by 2010. In the case of a REMIC Pool,  such  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 with respect to a regular interest it holds
in another REMIC.  Such investors who hold REMIC  Securities  either directly or
indirectly through certain  pass-through  entities may have their pro rata share
of such  expenses  allocated  to them as  additional  gross  income,  but may be
subject to such  limitation on  deductions.  In addition,  such expenses are not
deductible at all for purposes of computing the alternative minimum tax, and may
cause such  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.  With
respect to 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 such 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.  All such
expenses  will  be  allocable  to the  Residual  Securities.  In  general,  such
allocable   portion  will  be  determined  based  on  the  ratio  that  a  REMIC
Securityholder's income, determined on a daily basis, bears to the income of all
holders of Regular  Securities and Residual  Securities  with respect to a REMIC
Pool.  As a result,  individuals,  estates or trusts  holding  REMIC  Securities
(either  directly  or  indirectly  through  a  grantor  trust,  partnership,   S
corporation,  REMIC,  or certain other  pass-through  entities  described in the
foregoing  temporary Treasury  regulations) may have taxable income in excess of
the interest  income at the  pass-through  rate on Regular  Securities  that are
issued in a single Class or otherwise  consistently  with fixed investment trust
status or in excess of cash  distributions  for the  related  period on Residual
Securities.

      Taxation of Certain Foreign Investors

      Regular Securities

      Interest,  including  original issue  discount,  distributable  to Regular
Securityholders  who are non-resident  aliens,  foreign  corporations,  or other
non-U.S.  Persons,  generally  will  be  considered  "portfolio  interest"  and,
therefore,  generally will not be subject to 30% United States  withholding tax,
provided that (i) such interest is not effectively connected with the conduct of
a trade or  business  in the  United  States  of the  Securityholder,  (ii) such
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 (iii) such non-U.S. Person provides the Trustee, or the
person who would  otherwise be required to withhold tax from such  distributions
under Code Section 1441 or 1442,  with an  appropriate  statement,  signed under
penalties of perjury,  identifying the beneficial owner and stating, among other
things, that the beneficial owner of the Regular Security is a non-U.S.  Person.
If such  statement,  or any  other  required  statement,  is not  provided,  30%
withholding  will apply unless  reduced or eliminated  pursuant to an applicable
tax  treaty or unless  the  interest  on the  Regular  Security  is  effectively
connected  with the conduct of a trade or business  within the United  States by
such non-U.S.  Person. In the latter case, such non-U.S.  Person will be subject
to United States federal income tax at regular rates. Investors who are non-U.S.
Persons  should  consult  their own tax  advisors  regarding  the  specific  tax
consequences to them of owning a Regular Security.

      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 (i) the
Mortgage  Loans  were  issued  after  July 18,  1984 and (ii) the Trust  Fund or
segregated pool of assets therein (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

                                       109



of Residual  Securities--Limitations on Offset or Exemption of REMIC Income." 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
such non-U.S.  Persons,  30% (or lower treaty rate)  withholding will not apply.
Instead,  the amounts  paid to such  non-U.S.  Persons will be subject to United
States  federal  income  tax at regular  rates.  If 30% (or lower  treaty  rate)
withholding is applicable, such amounts generally will be taken into account for
purposes of  withholding  only when paid or otherwise  distributed  (or when the
Residual  Security  is  disposed  of) under rules  similar to  withholding  upon
disposition  of  debt  instruments  that  have  original  issue  discount.   See
"--Taxation  of  Owners  of  Residual  Securities--Tax-Related  Restrictions  on
Transfer  of  Residual  Securities--Foreign   Investors"  above  concerning  the
disregard of certain transfers having "tax avoidance potential."

      The Internal  Revenue  Service issued  temporary  regulations on August 1,
2006 (the  "Temporary  Regulations")  modifying  the  general  rule that  excess
inclusions from a REMIC residual  interest are not includible in the income of a
foreign person (or subject to withholding  tax) until paid or  distributed.  The
Temporary  Regulations are effective generally for interests in a REMIC residual
interest first acquired on or after August 1, 2006, and accelerate the time both
for reporting of, and  withholding  tax on, excess  inclusions  allocated to the
foreign equity holders of partnerships and certain other pass-through  entities.
The Temporary  Regulations also provide that excess inclusions are United States
source income.

      In the case of REMIC residual interests held by a foreign person through a
partnership,  the  Temporary  Regulations  deem the  amount of excess  inclusion
income allocated to the foreign partner to be received by the foreign partner on
the last day of the  partnership's  taxable year,  except to the extent that the
excess inclusion was required to be taken into account by the foreign partner at
an earlier time under section  860G(b) of the Code as a result of a distribution
by the  partnership to the foreign  partner or a disposition in whole or in part
of the foreign  partner's  indirect interest in the REMIC residual  interest.  A
disposition in whole or in part of the foreign  partner's  indirect  interest in
the REMIC residual interest may occur as a result of a termination of the REMIC,
a disposition of the partnership's residual interest in the REMIC, a disposition
of the foreign partner's interest in the partnership,  or any other reduction in
the foreign partner's  allocable share of the portion of the REMIC net income or
deduction allocated to the partnership.

      In  the  case  of a  residual  interest  held  by a  foreign  person  as a
shareholder of a real estate investment trust or regulated  investment  company,
as a  participant  in a  common  trust  fund or as a patron  in an  organization
subject to part I of  subchapter  T  (cooperatives),  the  foreign  person  must
include  in income the amount of excess  inclusion  allocated  to it at the same
time that other income from the trust,  company,  fund, or organization would be
taken into account.

      The Temporary  Regulations  also expressly make subject to withholding tax
excess inclusions  allocated to a foreign person (whether as a partner or holder
of an interest in a  pass-through  entity).  In addition,  in the case of excess
inclusions allocable to a foreign person as a partner, the Temporary Regulations
eliminate an important  exception to the withholding  requirements under which a
withholding  agent  unrelated  to a payee is  obligated to withhold on a payment
only to the extent that the withholding agent has control over the payee's money
or property and knows the facts giving rise to the payment.

      Investors who are non-U.S.  Persons  should consult their own tax advisors
regarding the specific tax consequences to them of owning Residual Securities.

      Backup Withholding

      Distributions made on the Regular  Securities,  and proceeds from the sale
of the Regular  Securities to or through  certain  brokers,  may be subject to a
"backup" withholding tax under Code Section 3406 of 28% (increasing to 31% after
2010) on "reportable payments" (including interest distributions, original issue
discount, and, under certain circumstances,  principal distributions) unless the
Regular Holder complies with certain reporting and/or certification  procedures,
including  the provision of its taxpayer  identification  number to the Trustee,
its agent or the broker who effected the sale of the Regular  Security,  or such
Holder is otherwise an exempt recipient under applicable provisions of the Code.
Any amounts to be withheld from distribution on the Regular  Securities would be
refunded by the IRS or allowed as a credit against the Regular  Holder's federal
income tax liability.  The Withholding  Regulations  change certain of the rules
relating to certain  presumptions  relating to information

                                       110



reporting and backup  withholding.  Non-U.S.  Persons are urged to contact their
own tax advisors  regarding the  application to them of backup  withholding  and
information reporting.

      Reporting Requirements

      Reports of accrued  interest,  original  issue  discount  and  information
necessary to compute the accrual of market discount will be made annually to the
IRS and to  individuals,  estates,  non-exempt and  non-charitable  trusts,  and
partnerships  who  are  either  holders  of  record  of  Regular  Securities  or
beneficial  owners who own Regular  Securities  through a broker or middleman as
nominee.  All brokers,  nominees and all other  non-exempt  holders of record of
Regular  Securities  (including   corporations,   non-calendar  year  taxpayers,
securities or commodities  dealers,  real estate investment  trusts,  investment
companies,  common trust funds,  thrift  institutions and charitable trusts) may
request such  information for any calendar quarter by telephone or in writing by
contacting the person  designated in Internal  Revenue  Service  Publication 938
with  respect to a  particular  Series of Regular  Securities.  Holders  through
nominees must request such information from the nominee.

      The IRS's Form 1066 has an  accompanying  Schedule Q, Quarterly  Notice to
Residual  Interest  Holders  of REMIC  Taxable  Income  or Net Loss  Allocation.
Treasury  regulations  require that Schedule Q be furnished by the REMIC Pool to
each  Residual  Holder  by the end of the  month  following  the  close  of each
calendar  quarter (41 days after the end of a quarter  under  proposed  Treasury
regulations)  in which the REMIC  Pool is in  existence).  Treasury  regulations
require  that, in addition to the foregoing  requirements,  information  must be
furnished quarterly to Residual Holders,  furnished annually, if applicable,  to
holders of Regular  Securities,  and filed annually with the IRS concerning Code
Section  67  expenses   (see   "--Taxes   That  May  Be  Imposed  on  the  REMIC
Pool--Limitations  on Deduction of Certain  Expenses"  above)  allocable to such
holders.  Furthermore,  under such  regulations,  information  must be furnished
quarterly  to  Residual  Holders,  furnished  annually  to  holders  of  Regular
Securities,  and filed  annually with the IRS  concerning  the percentage of the
REMIC Pool's assets  meeting the  qualified  asset tests  described  above under
"Characterization of Investments in REMIC Securities."

      Residual Holders should be aware that their responsibilities as holders of
the residual  interest in a REMIC Pool,  including the duty to account for their
shares of the REMIC  Pool's  income or loss on their  returns,  continue for the
life of the REMIC Pool,  even after the principal and interest on their Residual
Securities have been paid in full.

      Treasury  regulations  provide  that a Residual  Holder is not required to
treat items on its return  consistently with their treatment on the REMIC Pool's
return  if the  Holder  owns  100% of the  Residual  Securities  for the  entire
calendar year. Otherwise, each Residual Holder is required to treat items on its
returns consistently with their treatment on the REMIC Pool's return, unless the
Holder either files a statement  identifying  the  inconsistency  or establishes
that the  inconsistency  resulted from incorrect  information  received from the
REMIC Pool.  The IRS may assess a deficiency  resulting from a failure to comply
with  the  consistency   requirement   without   instituting  an  administrative
proceeding at the REMIC Pool level. Any person that holds a Residual Security as
a nominee for another  person may be required to furnish the related REMIC Pool,
in a manner to be provided in Treasury regulations, with the name and address of
such person and other specified information.

Grantor Trust Funds

      Classification of Grantor Trust Funds

      With  respect  to  each  Series  of  Grantor  Trust  Securities,  assuming
compliance with all provisions of the applicable Agreement,  the related Grantor
Trust Fund will be  classified  as a grantor  trust  under  subpart E, part I of
subchapter J of the Code and not as a partnership,  an association  taxable as a
corporation,  or a "taxable  mortgage  pool"  within the meaning of Code Section
7701(i).  Accordingly, each holder of a Grantor Trust Security generally will be
treated as the beneficial  owner of an undivided  interest in the Mortgage Loans
included in the Grantor Trust Fund.

                                       111



Standard Securities

      General

      Where there is no Retained Interest or "excess"  servicing with respect to
the  Mortgage  Loans  underlying  the  Securities  of a Series,  and where  such
Securities are not designated as "Stripped  Securities," the holder of each such
Security in such Series  (referred to herein as "Standard  Securities")  will be
treated as the owner of a pro rata undivided interest in the ordinary income and
corpus portions of the Grantor Trust Fund  represented by its Standard  Security
and will be considered the beneficial owner of a pro rata undivided  interest in
each  of  the   Mortgage   Loans,   subject  to  the   discussion   below  under
"--Recharacterization of Servicing Fees." Accordingly,  the holder of a Standard
Security of a particular Series will be required to report on its federal income
tax  return  its pro rata share of the entire  income  from the  Mortgage  Loans
represented by its Standard  Security,  including interest at the coupon rate on
such  Mortgage  Loans,  original  issue  discount  (if  any),  prepayment  fees,
assumption  fees,  and  late  payment  charges  received  by  the  Servicer,  in
accordance with such  Securityholder's  method of accounting.  A  Securityholder
generally  will  be  able to  deduct  its  share  of the  Servicing  Fee and all
administrative  and other  expenses  of the Trust  Fund in  accordance  with its
method of accounting, provided that such amounts are reasonable compensation for
services  rendered  to that  Grantor  Trust  Fund.  However,  investors  who are
individuals, estates or trusts who own Securities, either directly or indirectly
through  certain  pass-through  entities,  will be subject to  limitations  with
respect to certain itemized  deductions  described in Code Section 67, including
deductions   under  Code  Section  212  for  the  Servicing  Fee  and  all  such
administrative  and other expenses of the Grantor Trust Fund, to the extent that
such  deductions,  in the aggregate,  do not exceed two percent of an investor's
adjusted  gross  income.  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 of (i) 3% of the  excess,  if any,  of  adjusted  gross
income over a statutory  threshold  amount or (ii) 80% of the amount of itemized
deductions  otherwise  allowable for such year. These limitations will be phased
out and  eliminated  by 2010.  As a  result,  such  investors  holding  Standard
Securities,  directly or  indirectly  through a  pass-through  entity,  may have
aggregate  taxable income in excess of the aggregate  amount of cash received on
such Standard Securities with respect to interest at the pass-through rate or as
discount income on such Standard Securities.  In addition, such expenses are not
deductible at all for purposes of computing the alternative minimum tax, and may
cause such  investors to be subject to  significant  additional  tax  liability.
Moreover,  where there is Retained  Interest with respect to the Mortgage  Loans
underlying a Series of Securities  or where the servicing  fees are in excess of
reasonable  servicing  compensation,  the  transaction  will be  subject  to the
application of the "stripped  bond" and "stripped  coupon" rules of the Code, as
described  below under  "--Stripped  Securities"  and  "--Recharacterization  of
Servicing Fees," respectively.

      Holders of Standard  Securities,  particularly any Class of a Series which
is a  Subordinated  Security,  may incur  losses of interest or  principal  with
respect to the Mortgage Loans. Such losses would be deductible generally only as
described    above    under    "--REMICs--Taxation    of   Owners   of   Regular
Securities--Treatment of Losses," except that Securityholders on the cash method
of  accounting  would not be required  to report  qualified  stated  interest as
income until actual receipt.

      Tax Status

      With  respect to a Series,  Cadwalader,  Wickersham & Taft LLP or Hunton &
Williams LLP has advised the Depositor that, except with respect to a Trust Fund
consisting of Unsecured Home Improvement Loans:

      o     A  Standard  Security  owned  by  a  "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  which  is . . .  residential  real  property"  within  the
            meaning of Code Section  7701(a)(19)(C)(v),  provided  that the real
            property  securing the Mortgage  Loans  represented by that Standard
            Security is of the type described in such section of the Code.

      o     A Standard  Security owned by a 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 such assets will be  considered  "interest on  obligations
            secured by  mortgages on real  property"  to such extent  within the
            meaning of Code Section 856(c)(3)(B).

                                       112



      o     A Standard Security owned by a 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 extent that the assets of the related  Grantor
            Trust Fund consist of  "qualified  mortgages"  within the meaning of
            Code Section 860G(a)(3).

      An issue arises as to whether Buydown  Mortgage Loans may be characterized
in their entirety under the Code provisions cited in the first two bullet points
above or whether the amount qualifying for such treatment must be reduced by the
amount of the Buydown Funds. There is indirect authority supporting treatment of
an investment in a Buydown Mortgage Loan as entirely secured by real property if
the fair  market  value of the  real  property  securing  the loan  exceeds  the
principal amount of the loan at the time of issuance or acquisition, as the case
may be.  There is no assurance  that the  treatment  described  above is proper.
Accordingly,  Securityholders  are  urged  to  consult  their  own tax  advisors
concerning  the effects of such  arrangements  on the  characterization  of such
Securityholder's investment for federal income tax purposes.

      Premium and Discount

      Securityholders  are advised to consult  with their tax advisors as to the
federal income tax treatment of premium and discount arising either upon initial
acquisition of Standard Securities or thereafter.

      Premium. The treatment of premium incurred upon the purchase of a Standard
Security   will   be   determined    generally   as   described    above   under
"--REMICs--Taxation  of  Owners  of  Residual  Securities--Premium."  The  rules
allowing for the  amortization of premium are available with respect to Mortgage
Loans originated after September 27, 1985.

      Original Issue Discount. The original issue discount rules of Code Section
1271 through 1275 will be  applicable  to a  Securityholder's  interest in those
Mortgage Loans as to which the conditions for the  application of those sections
are met. Rules  regarding  periodic  inclusion of original issue discount income
generally are applicable to mortgages  originated after March 2, 1984. Under the
OID  Regulations,  original issue discount could arise by the charging of points
by the  originator of the  mortgages in an amount  greater than the statutory de
minimis exception, including a payment of points that is currently deductible by
the borrower under  applicable Code provisions or, under certain  circumstances,
by the  presence  of  "teaser"  rates on the  Mortgage  Loans.  See  "--Stripped
Securities" below regarding original issue discount on Stripped Securities.

      Original  issue  discount  generally  must be reported  as ordinary  gross
income as it accrues  under a constant  interest  method that takes into account
the compounding of interest, in advance of the cash attributable to such income.
Generally no prepayment assumption will be assumed for purposes of such accrual.
However,  Code Section  1272  provides for a reduction in the amount of original
issue  discount  includable  in the  income  of a holder of an  obligation  that
acquires the obligation  after its initial  issuance at a price greater than the
sum of the  original  issue  price and the  previously  accrued  original  issue
discount, less prior payments of principal.  Accordingly, if such Mortgage Loans
acquired by a  Securityholder  are purchased at a price equal to the then unpaid
principal amount of such Mortgage Loans, no original issue discount attributable
to the difference  between the issue price and the original  principal amount of
such Mortgage Loans (i.e., points) will be includable by such holder.

      Market  Discount.  Securityholders  also  will be  subject  to the  market
discount  rules to the  extent  that the  conditions  for  application  of those
sections are met.  Market  discount on the Mortgage Loans will be determined and
will be reported as ordinary  income  generally  in the manner  described  above
under  "--REMICs--Taxation  of Owners of Regular  Securities--Market  Discount,"
except  that the  ratable  accrual  methods  described  therein  will not apply.
Rather,  the holder will accrue  market  discount  pro rata over the life of the
Mortgage  Loans,  unless the  constant  yield  method is elected.  Generally  no
prepayment assumption will be assumed for purposes of such accrual.

                                       113



      Recharacterization of Servicing Fees

      If the servicing fees paid to a Servicer were deemed to exceed  reasonable
servicing compensation, the amount of such excess would represent neither income
nor a deduction to Securityholders.  In this regard,  there are no authoritative
guidelines  for federal  income tax purposes as to either the maximum  amount of
servicing  compensation that may be considered reasonable in the context of this
or similar  transactions  or whether,  in the case of Standard  Securities,  the
reasonableness  of servicing  compensation  should be  determined  on a weighted
average or  loan-by-loan  basis.  If a loan-by-loan  basis is  appropriate,  the
likelihood that such amount would exceed reasonable servicing compensation as to
some of the Mortgage  Loans would be increased.  IRS guidance  indicates  that a
servicing fee in excess of reasonable  compensation  ("excess  servicing")  will
cause the Mortgage  Loans to be treated  under the "stripped  bond" rules.  Such
guidance  provides  safe  harbors  for  servicing  deemed to be  reasonable  and
requires  taxpayers to demonstrate that the value of servicing fees in excess of
such amounts is not greater than the value of the services provided.

      Accordingly,  if the IRS's  approach is upheld,  a Servicer who receives a
servicing  fee in  excess  of such  amounts  would be  viewed  as  retaining  an
ownership  interest in a portion of the interest payments on the Mortgage Loans.
Under the rules of Code Section 1286,  the  separation of ownership of the right
to receive some or all of the interest  payments on an obligation from the right
to receive some or all of the principal  payments on the obligation would result
in treatment of such Mortgage Loans as "stripped  coupons" and "stripped bonds."
Subject to the de minimis rule discussed below under "Stripped Securities," each
stripped  bond or stripped  coupon  could be  considered  for this  purpose as a
non-interest  bearing  obligation  issued  on the date of issue of the  Standard
Securities, and the original issue discount rules of the Code would apply to the
holder  thereof.  While  Securityholders  would  still be  treated  as owners of
beneficial  interests in a grantor trust for federal  income tax  purposes,  the
corpus of such trust could be viewed as  excluding  the portion of the  Mortgage
Loans the ownership of which is attributed to the Servicer, or as including such
portion as a second Class of equitable interest. Applicable Treasury regulations
treat  such an  arrangement  as a fixed  investment  trust,  since the  multiple
Classes  of trust  interests  should be treated  as merely  facilitating  direct
investments  in the trust  assets  and the  existence  of  multiple  Classes  of
ownership  interests  is  incidental  to  that  purpose.  In  general,   such  a
recharacterization  should not have any  significant  effect  upon the timing or
amount of income reported by a  Securityholder,  except that the income reported
by a cash method holder may be slightly accelerated. See "--Stripped Securities"
below for a further  description of the federal income tax treatment of stripped
bonds and stripped coupons.

      Sale or Exchange of Standard Securities

      Upon sale or  exchange of a Standard  Securities,  a  Securityholder  will
recognize  gain or loss equal to the difference  between the amount  realized on
the sale and its aggregate adjusted basis in the Mortgage Loans and other assets
represented by the Security. In general, the aggregate adjusted basis will equal
the  Securityholder's  cost for the  Standard  Security,  exclusive  of  accrued
interest, increased by the amount of any income previously reported with respect
to the Standard  Security and  decreased by the amount of any losses  previously
reported  with  respect  to  the  Standard   Security  and  the  amount  of  any
distributions (other than accrued interest) received thereon. Except as provided
above with  respect to market  discount on any  Mortgage  Loans,  and except for
certain financial institutions subject to the provisions of Code Section 582(c),
any such gain or loss  generally  would be capital  gain or loss if the Standard
Security was held as a capital  asset.  However,  gain on the sale of a Standard
Security will be treated as ordinary  income (i) if a Standard  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  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 with respect to any prior
disposition of property that was held as part of such transaction or (ii) in the
case of a  non-corporate  taxpayer,  to the  extent  such  taxpayer  has made an
election  under  Code  Section  163(d)(4)  to have net  capital  gains  taxed as
investment  income at ordinary income rates.  Long-term capital gains of certain
noncorporate  taxpayers  generally  are subject to a lower maximum tax rate than
ordinary income or short-term  capital gains of such taxpayers for property held
for more than one year. The maximum tax rate for  corporations  currently is the
same with respect to both ordinary income and capital gains.

                                       114



Stripped Securities

      General

      Pursuant to Code Section 1286, the separation of ownership of the right to
receive some or all of the principal payments on an obligation from ownership of
the  right  to  receive  some or all of the  interest  payments  results  in the
creation of "stripped  bonds" with respect to principal  payments and  "stripped
coupons"  with respect to interest  payments.  For purposes of this  discussion,
Securities  that are subject to those  rules will be  referred  to as  "Stripped
Securities."  The Securities will be subject to those rules if (i) the Depositor
or any of its  affiliates  retains  (for  its own  account  or for  purposes  of
resale), in the form of Retained Interest or otherwise, an ownership interest in
a portion of the payments on the Mortgage  Loans,  (ii) the  Depositor or any of
its affiliates is treated as having an ownership  interest in the Mortgage Loans
to the  extent  it is paid (or  retains)  servicing  compensation  in an  amount
greater than  reasonable  consideration  for servicing  the Mortgage  Loans (see
"--Standard  Securities--Recharacterization of Servicing Fees" above), and (iii)
a  Class  of  Securities  are  issued  in  two or  more  Classes  or  subclasses
representing the right to non-pro-rata percentages of the interest and principal
payments on the Mortgage Loans.

      In general,  a holder of a Stripped  Security  will be  considered  to own
"stripped  bonds" with  respect to its pro rata share of all or a portion of the
principal  payments on each Mortgage Loan and/or "stripped coupons" with respect
to its pro rata  share of all or a  portion  of the  interest  payments  on each
Mortgage  Loan,  including  the  Stripped  Security's  allocable  share  of  the
servicing  fees paid to a  Servicer,  to the  extent  that  such fees  represent
reasonable  compensation for services  rendered.  See the discussion above under
"--Standard Securities--Recharacterization of Servicing Fees." Although not free
from doubt, for purposes of reporting to Stripped Securityholders, the servicing
fees will be allocated to the Classes of Stripped  Securities  in  proportion to
the distributions to such Classes for the related period or periods.  The holder
of a Stripped  Security  generally  will be entitled to a deduction each year in
respect  of  the   servicing   fees,  as  described   above  under   "--Standard
Securities--General," subject to the limitation described therein.

      Code Section 1286 treats a stripped bond or a stripped coupon generally as
an  obligation  issued  at an  original  issue  discount  on the date  that such
stripped  interest is purchased.  Although the treatment of Stripped  Securities
for federal income tax purposes is not clear in certain  respects,  particularly
where such  Stripped  Securities  are  issued  with  respect to a Mortgage  Pool
containing  variable-rate  Mortgage  Loans,  the  Depositor  has been advised by
counsel that (i) the Grantor Trust Fund will be treated as a grantor trust under
subpart E, part I of subchapter J of the Code and not as an association  taxable
as a corporation or a "taxable mortgage pool" within the meaning of Code Section
7701(i),  and  (ii)  each  Stripped  Security  should  be  treated  as a  single
installment  obligation for purposes of calculating  original issue discount and
gain or loss on disposition. This treatment is based on the interrelationship of
Code Section 1286,  Code Sections  1272 through 1275,  and the OID  Regulations.
Although it is possible that  computations  with respect to Stripped  Securities
could be made in one of the ways described below under  "--Possible  Alternative
Characterizations," the OID Regulations state, in general, that two or more debt
instruments  issued  by  a  single  issuer  to a  single  investor  in a  single
transaction  should be treated as a single  debt  instrument.  Accordingly,  for
original issue discount purposes, all payments on any Stripped Securities should
be aggregated and treated as though they were made on a single debt  instrument.
The Pooling and  Servicing  Agreement  will  require  that the Trustee  make and
report all computations  described below using this aggregate  approach,  unless
substantial legal authority requires otherwise.

      Furthermore,  Treasury  regulations  provide for  treatment  of a Stripped
Security  as a single debt  instrument  issued on the date it is  purchased  for
purposes of calculating  any original issue  discount.  In addition,  under such
regulations,  a Stripped  Security  that  represents a right to payments of both
interest  and  principal  may be viewed  either as issued  with  original  issue
discount or market discount (as described below), at a de minimis original issue
discount,  or,  presumably,  at a premium.  This  treatment  indicates  that the
interest  component  of such a Stripped  Security  would be treated as qualified
stated interest under the OID  Regulations,  assuming it is not an interest-only
or super-premium Stripped Security.  Further, these regulations provide that the
purchaser  of such a Stripped  Security  will be  required  to  account  for any
discount as market  discount  rather than original  issue discount if either (i)
the initial  discount with respect to the Stripped  Security was treated as zero
under the de minimis  rule,  or (ii) no more than 100 basis  points in excess of
reasonable servicing is stripped off the related Mortgage Loans. Any such market
discount  would be reportable as described  above under  "--REMICs--Taxation  of
Owners of Regular Securities--Market Discount," without regard to the de minimis
rule  therein,  assuming  that a  prepayment  assumption  is  employed  in  such
computation.

                                       115



      The holder of a Stripped Security will be treated as owning an interest in
each of the Mortgage  Loans held by the Grantor Trust Fund and will recognize an
appropriate share of the income and expenses associated with the Mortgage Loans.
Accordingly,  an  individual,  trust or estate  that holds a  Stripped  Security
directly or through a pass-through  entity will be subject to the limitations on
deductions imposed by Code Sections 67 and 68.

      A holder of a Stripped Security,  particularly any Class of a Series which
is a  Subordinated  Security,  may deduct  losses  incurred  with respect to the
Stripped Security as described above under "--Standard Securities--General."

      Status of Stripped Securities

      No specific  legal  authority  exists as to whether the  character  of the
Stripped Securities,  for federal income tax purposes,  will be the same as that
of the Mortgage  Loans.  Although the issue is not free from doubt,  counsel has
advised the Depositor  that,  except with respect to a Trust Fund  consisting of
Unsecured  Home  Improvement  Loans,  Stripped  Securities  owned by  applicable
holders  should be  considered  to  represent  "real estate  assets"  within the
meaning of Code Section  856(c)(4)(A),  "obligation[s] . . . principally secured
by an interest in real property which is . . .  residential  real estate" within
the  meaning  of Code  Section  860G(a)(3)(A),  and  "loans . . .  secured by an
interest in real property" within the meaning of Code Section 7701(a)(19)(C)(v),
and interest (including original issue discount) income attributable to Stripped
Securities should be considered to represent "interest on obligations secured by
mortgages on real  property"  within the meaning of Code  Section  856(c)(3)(B),
provided  that in each case the  Mortgage  Loans and  interest on such  Mortgage
Loans qualify for such  treatment.  The  application of such Code  provisions to
Buydown  Mortgage Loans is uncertain.  See "--Standard  Securities--Tax  Status"
above.

      Taxation of Stripped Securities

      Original Issue Discount. Except as described above under "--General," each
Stripped  Security will be  considered to have been issued at an original  issue
discount for federal  income tax purposes.  Original issue discount with respect
to a Stripped  Security  must be included in ordinary  income as it accrues,  in
accordance  with a constant yield method that takes into account the compounding
of interest,  which may be prior to the receipt of the cash attributable to such
income.  Based in part on the issue  discount  required  to be  included  in the
income of a holder of a Stripped  Security  (referred to in this discussion as a
"Stripped Securityholder") in any taxable year likely will be computed generally
as   described   above   under   "--REMICs--Taxation   of   Owner   of   Regular
Securities--Original  Issue Discount" and "--Variable Rate Regular  Securities."
However,  with the apparent  exception of a Stripped  Security  qualifying  as a
market discount obligation as described above under "--General," the issue price
of a Stripped  Security will be the purchase price paid by each holder  thereof,
and the stated redemption price at maturity will include the aggregate amount of
the payments,  other than qualified stated interest,  to be made on the Stripped
Security to such Securityholder, presumably under the Prepayment Assumption.

      If the Mortgage  Loans prepay at a rate either  faster or slower than that
under the  Prepayment  Assumption,  a  Securityholder's  recognition of original
issue discount will be either  accelerated or decelerated and the amount of such
original issue discount will be either  increased or decreased  depending on the
relative  interests in principal and interest on each Mortgage Loan  represented
by such  Securityholder's  Stripped Security.  While the matter is not free from
doubt, the holder of a Stripped  Security should be entitled in the year that it
becomes  certain  (assuming  no further  prepayments)  that the holder  will not
recover a portion of its adjusted basis in such Stripped Security to recognize a
loss (which may be a capital loss) equal to such portion of unrecoverable basis.

      As an alternative to the method described above, the fact that some or all
of the interest  payments  with respect to the Stripped  Securities  will not be
made if the Mortgage  Loans are prepaid  could lead to the  interpretation  that
such  interest  payments  are  "contingent"   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 prepayable securities such as the
Stripped  Securities.  However,  if final  regulations  dealing with  contingent
interest with respect to the Stripped  Securities  apply the same  principles as
the OID  Regulations,  such  regulations may lead to different  timing of income
inclusion  that  would  be the  case  under  the OID  Regulations.  Furthermore,
application of such principles could lead to the characterization of gain on the
sale of contingent  interest Stripped  Securities as ordinary income.  Investors
should  consult their tax advisors  regarding the  appropriate  tax treatment of
Stripped Securities.

                                       116



      Sale or Exchange of  Stripped  Securities.  Sale or exchange of a Stripped
Security  prior  to its  maturity  will  result  in gain or  loss  equal  to the
difference,  if any,  between  the  amount  received  and  the  Securityholder's
adjusted   basis  in  such   Stripped   Security,   as  described   above  under
"--REMICs--Taxation of Owners of Regular Securities--Sale or Exchange of Regular
Securities."  Gain or loss  from the sale or  exchange  of a  Stripped  Security
generally  will be capital  gain or loss to the  Securityholder  if the Stripped
Security is held as a "capital  asset"  within the meaning of Code Section 1221,
and will be long-term or short-term  depending on whether the Stripped  Security
has been held for the long-term  capital gain holding  period  (currently,  more
than one year).  To the extent that a subsequent  purchaser's  purchase price is
exceeded by the remaining payments on the Stripped  Securities,  such subsequent
purchaser  will be required for federal income tax purposes to accrue and report
such excess as if it were original issue discount in the manner described above.
It is not clear for this purpose whether the assumed  prepayment rate that is to
be used in the case of a  Securityholder  other than an original  Securityholder
should be the Prepayment  Assumption or a new rate based on the circumstances at
the date of subsequent purchase.

      Purchase of More Than One Class of Stripped  Securities.  When an investor
purchases more than one Class of Stripped  Securities,  it is currently  unclear
whether for federal  income tax  purposes  such  Classes of Stripped  Securities
should be treated  separately or aggregated for purposes of the rules  described
above.

      Possible  Alternative  Characterization.   The  characterizations  of  the
Stripped Securities discussed above are not the only possible interpretations of
the applicable Code provisions.  For example,  the Securityholder may be treated
as the  owner of (i) one  installment  obligation  consisting  of such  Stripped
Security's  pro rata share of the  payments  attributable  to  principal on each
Mortgage Loan and a second  installment  obligation  consisting of such Stripped
Security's  pro rata share of the  payments  attributable  to  interest  on each
Mortgage  Loan,  (ii) as many  stripped  bonds or stripped  coupons as there are
scheduled  payments of principal and/or interest on each Mortgage Loan, or (iii)
a separate  installment  obligation  for each Mortgage  Loan,  representing  the
Stripped  Security's pro rata share of payments of principal  and/or interest to
be made with respect thereto.  Alternatively,  the holder of one or more Classes
of  Stripped  Securities  may be treated  as the owner of a pro rata  fractional
undivided  interest  in each  Mortgage  Loan to the  extent  that such  Stripped
Security, or Classes of Stripped Securities in the aggregate, represent the same
pro rata portion of principal  and interest on each such  Mortgage  Loan,  and a
stripped bond or stripped coupon (as the case may be), treated as an installment
obligation or  contingent  payment  obligation,  as to the  remainder.  Treasury
regulations  regarding original issue discount on stripped  obligations make the
foregoing  interpretations  less likely to be  applicable.  The preamble to such
regulations  states that they are premised on the assumption that an aggregation
approach is appropriate  for  determining  whether  original issue discount on a
stripped  bond or  stripped  coupon is de  minimis,  and  solicits  comments  on
appropriate rules for aggregating stripped bonds and stripped coupons under Code
Section 1286.

      Because of these possible varying characterizations of Stripped Securities
and the resultant differing treatment of income recognition, Securityholders are
urged to  consult  their own tax  advisors  regarding  the proper  treatment  of
Stripped Securities for federal income tax purposes.

      Reporting Requirements and Backup Withholding

      The Trustee will furnish,  within a reasonable  time after the end of each
calendar  year,  to each  Securityholder  at any time  during  such  year,  such
information  (prepared on the basis  described  above) as is necessary to enable
such Securityholder to prepare its federal income tax returns.  Such information
will include the amount of original issue discount accrued on Securities held by
persons other than  Securityholders  exempted  from the reporting  requirements.
However,  the amount  required to be reported by the Trustee may not be equal to
the proper amount of original issue discount  required to be reported as taxable
income by a Securityholder, other than an original Securityholder that purchased
at the issue price.  In  particular,  in the case of Stripped  Securities,  such
reporting  will be based upon a  representative  initial  offering price of each
Class of Stripped  Securities.  The Trustee will also file such  original  issue
discount  information  with the IRS.  If a  Securityholder  fails to  supply  an
accurate  taxpayer  identification  number or if the  Secretary  of the Treasury
determines  that a  Securityholder  has not  reported  all interest and dividend
income required to be shown on his federal income tax return, backup withholding
may be required in respect of any reportable payments,  as described above under
"--REMICs--Taxation of Certain Foreign Investors--Backup Withholding."

                                       117



      On  January  24,  2006,  the  Internal  Revenue  Service  published  final
regulations which establish a reporting  framework for interests in "widely held
fixed investment trusts" and place the responsibility of reporting on the person
in the ownership  chain who holds an interest for a beneficial  owner.  A widely
held fixed investment trust is defined as an arrangement classified as a "trust"
under Treasury  Regulation Section  301.7701-4(c)  which is a U.S. Person and in
which any interest is held by a middleman, which includes, but is not limited to
(i) a custodian of a person's account, (ii) a nominee and (iii) a broker holding
an interest for a customer in street name. The Trustee, or its designated agent,
will be required to calculate and provide information to requesting persons with
respect to the related Trust in accordance with these new regulations  beginning
with respect to the 2007 calendar year.  The Trustee (or its designated  agent),
or the applicable middleman (in the case of interests held through a middleman),
will be  required  to file  information  returns  with the IRS and  provide  tax
information  statements  to  Certificateholders  in  accordance  with  these new
regulations after December 31, 2007.

      Taxation of Certain Foreign Investors

      To the extent that a Security  evidences  ownership in Mortgage Loans that
are issued on or before July 18, 1984,  interest or original issue discount paid
by the  person  required  to  withhold  tax under Code  Section  1441 or 1442 to
nonresident aliens,  foreign corporations,  or other non-U.S.  Persons generally
will be subject to 30% United States  withholding tax, or such lower rate as may
be provided for interest by an applicable  tax treaty.  Accrued  original  issue
discount  recognized  by the  Securityholder  on the sale or  exchange of such a
Security also will be subject to federal income tax at the same rate.

      Treasury regulations provide that interest or original issue discount paid
by the  Trustee  or other  withholding  agent to a  non-U.S.  Person  evidencing
ownership  interest  in  Mortgage  Loans  issued  after  July 18,  1984  will be
"portfolio interest" and will be treated in the manner, and such persons will be
subject  to  the  same   certification   requirements,   described  above  under
"--REMICs--Taxation of Certain Foreign Investors--Regular Securities."

Partnership Trust Funds

      Classification of Partnership Trust Funds

      With respect to each Series of Partnership  Securities or Debt Securities,
Cadwalader,  Wickersham  & Taft LLP or Hunton & Williams  LLP will  deliver  its
opinion  that  the  Trust  Fund  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 terms of the  applicable  Agreement and related  documents  will be complied
with,  and on  counsel's  conclusion  that the nature of the income of the Trust
Fund will exempt it from the rule that certain publicly traded  partnerships are
taxable as corporations.

      Characterization  of  Investments  in  Partnership   Securities  and  Debt
Securities

      For federal  income tax  purposes,  (i)  Partnership  Securities  and 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  which is . . . residential  real property"  within the meaning of Code
Section  7701(a)(19)(C)(v)  and (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),  and Debt Securities held by a real estate
investment  trust will not constitute "real estate assets" within the meaning of
Code Section  856(c)(4)(A),  but  Partnership  Securities  held by a real estate
investment  trust will  qualify  under those  sections  based on the real estate
investments  trust's  proportionate  interest  in the assets of the  Partnership
Trust Fund qualifying for such treatments based on capital accounts.

                                       118



      Taxation of Debt Securityholders

      Treatment of the Debt Securities as Indebtedness

      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,
with respect to each Series of Debt  Securities,  Cadwalader,  Wickersham & Taft
LLP or Hunton & Williams LLP 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.

      If, contrary to the opinion of counsel, the IRS successfully asserted that
the Debt  Securities  were not debt for federal  income tax  purposes,  the Debt
Securities  might be treated as equity  interests in the Partnership  Trust, and
the timing and amount of income allocable to holders of such Debt Securities may
be different than as described in the following paragraph.

      Debt Securities generally will be subject to the same rules of taxation as
Regular Securities issued by a REMIC, as described above, except that (i) income
reportable on Debt  Securities is not required to be reported  under the accrual
method unless the holder  otherwise uses the accrual method and (ii) the special
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."

      Taxation of Owners of Partnership Securities

      Treatment of the Partnership Trust Fund as a Partnership

      If so specified in the  applicable  prospectus  supplement,  the Depositor
will agree, and the Securityholders  will agree by their purchase of Securities,
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
Securityholders  (including  the  Depositor),  and the Debt  Securities (if any)
being  debt of the  partnership.  However,  the proper  characterization  of the
arrangement  involving the Partnership  Trust Fund, the Partnership  Securities,
the  Debt  Securities,  and the  Depositor  is not  clear,  because  there is no
authority on transactions closely comparable to that contemplated herein.

      A variety of  alternative  characterizations  are  possible.  For example,
because  one or more of the  Classes  of  Partnership  Securities  have  certain
features  characteristic of debt, the Partnership Securities might be considered
debt of the Depositor or the Partnership  Trust Fund. Any such  characterization
would not result in materially  adverse tax consequences to  Securityholders  as
compared to the  consequences  from treatment of the  Partnership  Securities as
equity in a partnership,  described below. The following discussion assumes that
the Partnership Securities represent equity interests in a partnership.

      Partnership Taxation

      As a  partnership,  the  Partnership  Trust  Fund will not be  subject  to
federal income tax. Rather,  each  Securityholder will be required to separately
take into  account  such  holder's  allocated  share of income,  gains,  losses,
deductions and credits of the Partnership Trust Fund. It is anticipated that the
Partnership Trust Fund's income will consist primarily of interest earned on the
Mortgage Loans (including appropriate adjustments for market discount,  original
issue  discount and bond  premium) as  described  above under  "--Grantor  Trust
Funds-- Standard Securities--General" and "--Premium and Discount") and any gain
upon collection or disposition of 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 Debt Securities.

      The tax items of a partnership are allocable to the partners in accordance
with the Code,  Treasury  regulations and the partnership  agreement  (here, the
Agreements and related  documents).  The applicable  Agreement will provide,  in
general,  that the  Securityholders  will be  allocated  taxable  income  of the
Partnership  Trust Fund for each  Collection  Period equal to the sum of (i) the
interest that accrues on the  Partnership  Securities  in accordance  with their
terms for such Collection Period,  including interest accruing at the applicable
pass-through

                                       119



rate for such  Collection  Period and interest on amounts  previously due on the
Partnership Securities but not yet distributed;  (ii) any Partnership Trust Fund
income  attributable  to discount on the Mortgage Loans that  corresponds to any
excess of the principal amount of the Partnership  Securities over their initial
issue   price;   and  (iii)  any  other   amounts  of  income   payable  to  the
Securityholders  for such Collection Period.  Such allocation will be reduced by
any amortization by the Partnership Trust Fund of premium on Mortgage Loans that
corresponds  to any excess of the issue  price of  Partnership  Securities  over
their principal  amount.  All remaining  taxable income of the Partnership Trust
Fund will be allocated to the  Depositor.  Based on the economic  arrangement of
the parties,  this approach for allocating  Partnership Trust Fund income should
be permissible under applicable Treasury regulations,  although no assurance can
be given  that the IRS  would  not  require  a  greater  amount  of income to be
allocated  to  Securityholders.  Moreover,  even under the  foregoing  method of
allocation,  Securityholders  may  be  allocated  income  equal  to  the  entire
pass-through  rate plus the other  items  described  above even though the Trust
Fund might not have sufficient cash to make current cash  distributions  of such
amount.  Thus,  cash basis  holders will in effect be required to report  income
from the  Partnership  Securities on the accrual basis and  Securityholders  may
become liable for taxes on  Partnership  Trust Fund income even if they have not
received cash from the Partnership Trust Fund to pay such taxes.

      Part or all of the taxable income allocated to a Securityholder  that is a
pension,  profit  sharing or employee  benefit plan or other  tax-exempt  entity
(including an individual  retirement account) may constitute "unrelated business
taxable income" generally taxable to such a holder under the Code.

      A share of expenses of the  Partnership  Trust Fund (including fees of the
Master Servicer but not interest expense) allocable to an individual,  estate or
trust Securityholder  would be miscellaneous  itemized deductions subject to the
limitations    described   above   under   "--Grantor   Trust    Funds--Standard
Securities--General".  Accordingly,  such deductions  might be disallowed to the
individual in whole or in part and might result in such holder being taxed on an
amount of income that exceeds the amount of cash  actually  distributed  to such
holder over the life of the Partnership Trust Fund.

      Discount income or premium amortization with respect to each Mortgage Loan
would  be  calculated  in a  manner  similar  to  the  description  above  under
"--Grantor  Trust  Funds--Standard   Securities--General"   and  "--Premium  and
Discount." Notwithstanding such description, it is intended that the Partnership
Trust Fund will make all tax calculations  relating to income and allocations to
Securityholders on an aggregate basis with respect to all Mortgage Loans held by
the  Partnership  Trust Fund  rather  than on a Mortgage  Loan-by-Mortgage  Loan
basis. If the IRS were to require that such  calculations be made separately for
each  Mortgage  Loan,  the  Partnership  Trust Fund might be  required  to incur
additional  expense,  but it is  believed  that  there  would not be a  material
adverse effect on Securityholders.

      Discount and Premium

      It is not  anticipated  that the Mortgage Loans will have been issued with
original issue discount and,  therefore,  the Partnership  Trust Fund should not
have original issue  discount  income.  However,  the purchase price paid by the
Partnership  Trust Fund for the  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 discount,  as the
case  may be.  See  "--Grantor  Trust  Funds--Standard  Securities--Premium  and
Discount."  (As  indicated  above,  the  Partnership  Trust  Fund will make this
calculation  on an aggregate  basis,  but might be required to recompute it on a
Mortgage Loan-by-Mortgage Loan basis).

      If the  Partnership  Trust Fund  acquires the  Mortgage  Loans at a market
discount or premium,  the Partnership  Trust Fund will elect to include any such
discount in income  currently as it accrues over the life of the Mortgage  Loans
or to offset any such premium against  interest income on the Mortgage Loans. As
indicated  above, a portion of such market discount income or premium  deduction
may be allocated to Securityholders.

      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  such a  termination  occurs,  it  would  cause  a  deemed
contribution of the assets of a

                                       120



Partnership  Trust Fund (the "old  partnership") to a new Partnership Trust Fund
(the "new  partnership") in exchange for interests in the new partnership.  Such
interests would be deemed  distributed to the partners of the old partnership in
liquidation  thereof,  which  would  not  constitute  a sale  or  exchange.  The
Partnership Trust Fund will not comply with certain technical  requirements that
might  apply  when such a  constructive  termination  occurs.  As a result,  the
Partnership  Trust Fund may be subject to certain  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 due to lack
of data.

      Disposition of Securities

      Generally,  capital  gain  or  loss  will  be  recognized  on  a  sale  of
Partnership  Securities in an amount equal to the difference  between the amount
realized  and the  seller's  tax basis in the  Partnership  Securities  sold.  A
Securityholder's  tax basis in an Partnership  Security will generally equal the
holder's cost increased by the holder's  share of Partnership  Trust Fund income
(includable in income) and decreased by any distributions  received with respect
to such Partnership Security. In addition, both the tax basis in the Partnership
Securities and the amount  realized on a sale of an  Partnership  Security would
include the holder's share of the Debt  Securities and other  liabilities of the
Partnership Trust Fund. A holder acquiring  Partnership  Securities at different
prices may be required to maintain a single aggregate adjusted tax basis in such
Partnership  Securities,  and,  upon  sale or other  disposition  of some of the
Partnership  Securities,  allocate a portion of such  aggregate tax basis to the
Partnership  Securities  sold (rather than  maintaining  a separate tax basis in
each  Partnership  Security for purposes of computing  gain or loss on a sale of
that Partnership Security).

      Any  gain  on the  sale  of a  Partnership  Security  attributable  to the
holder's share of  unrecognized  accrued  market  discount on the Mortgage Loans
would  generally be treated as ordinary income to the holder and would give rise
to special  tax  reporting  requirements.  The  Partnership  Trust Fund does not
expect to have any other assets that would give rise to such  special  reporting
considerations.  Thus,  to  avoid  those  special  reporting  requirements,  the
Partnership  Trust Fund will elect to include  market  discount  in income as it
accrues.

      If a Securityholder 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  Securities  that exceeds the aggregate
cash distributions with respect thereto, such excess will generally give rise to
a capital loss upon the retirement of the Partnership Securities.

      Allocations Between Transferors and Transferees

      In general, the Partnership Trust Fund's taxable income and losses will be
determined each Collection Period and the tax items for a particular  Collection
Period  will be  apportioned  among the  Securityholders  in  proportion  to the
principal amount of Partnership  Securities owned by them as of the close of the
last day of such Collection Period. As a result, a holder purchasing Partnership
Securities  may be allocated  tax items (which will affect its tax liability and
tax basis) attributable to periods before the actual transaction.

      The use of such a  Collection  Period  convention  may not be permitted by
existing regulations.  If a Collection 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
Securityholders.  The Depositor  will be  authorized  to revise the  Partnership
Trust Fund's method of allocation between transferors and transferees to conform
to a method permitted by future regulations.

                                       121



      Section 731 Distributions

      In the  case of any  distribution  to a  Securityholder,  no gain  will be
recognized  to that  Securityholder  to the extent  that the amount of any money
distributed  with respect to such Security does not exceed the adjusted basis of
such Securityholder's interest in the Security. To the extent that the amount of
money  distributed  exceeds such  Securityholder's  adjusted basis, gain will be
currently  recognized.  In the case of any distribution to a Securityholder,  no
loss  will  be  recognized  except  upon  a  distribution  in  liquidation  of a
Securityholder's  interest. Any gain or loss recognized by a Securityholder will
be capital gain or loss.

      Section 754 Election

      In the event that a Securityholder  sells its Partnership  Securities at a
profit (loss), the purchasing Securityholder will have a higher (lower) basis in
the Partnership Securities than the selling Securityholder had. The tax basis of
the Partnership Trust Fund's assets would not be adjusted to reflect that higher
(or lower)  basis  unless the  Partnership  Trust Fund were to file an  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 will not make such an  election.  As a result,  a  Securityholder  might be
allocated a greater or lesser amount of Partnership Trust Fund income than would
be appropriate based on its own purchase price for Partnership Securities.

      Administrative Matters

      The Trustee is required to keep or have kept  complete and accurate  books
of the  Partnership  Trust Fund.  Such books will be  maintained  for  financial
reporting  and tax  purposes  on an  accrual  basis and the  fiscal  year of the
Partnership  Trust  Fund will be the  calendar  year.  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  Securityholder's
allocable share of items of Partnership Trust Fund income and expense to holders
and the  IRS on  Schedule  K-1.  The  Trustee  will  provide  the  Schedule  K-1
information to nominees that fail to provide the Partnership Trust Fund with the
information  statement  described  below and such  nominees  will be required to
forward such information to the beneficial owners of the Partnership Securities.
Generally,   holders  must  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 such inconsistencies.

      Under  Section  6031  of the  Code,  any  person  that  holds  Partnership
Securities  as a nominee  at any time  during a  calendar  year is  required  to
furnish  the  Partnership  Trust  Fund  with  a  statement   containing  certain
information on the nominee, the beneficial owners and the Partnership Securities
so  held.  Such  information   includes  (i)  the  name,  address  and  taxpayer
identification  number of the nominee and (ii) as to each  beneficial  owner (x)
the name,  address and  identification  number of such person,  (y) 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 (z) certain information on Partnership  Securities
that were held,  bought or sold on behalf of such person throughout the year. In
addition,  brokers and financial  institutions that hold Partnership  Securities
through a nominee are required to furnish directly to the Trustee information as
to themselves and their ownership of Partnership  Securities.  A clearing agency
registered  under Section 17A of the Exchange Act is not required to furnish any
such  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.

      The Depositor will be designated as the tax matters partner in the Pooling
and Servicing  Agreement and, as such, will be responsible for  representing the
Securityholders   in  any  dispute   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 until three years after the date on which the
partnership  information return is filed. 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 Securityholders,
and,  under  certain  circumstances,  a  Securityholder  may be  precluded  from
separately  litigating  a

                                       122



proposed  adjustment to the items of the  Partnership  Trust Fund. An adjustment
could also result in an audit of a  Securityholder's  returns and adjustments of
items not related to the income and losses of the Partnership Trust Fund.

      Tax Consequences to Foreign Securityholders

      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-U.S.  Persons,  because there is no clear
authority  dealing  with that issue under facts  substantially  similar to those
described  herein.  Although it is not expected that the Partnership  Trust Fund
would be engaged in a trade or business in the United States for such  purposes,
if so specified in the applicable prospectus  supplement,  the Partnership Trust
Fund may  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 may withhold on the portion of its taxable income that is
allocable to Securityholders  who are non-U.S.  Persons pursuant to Section 1446
of the Code,  as if such income were  effectively  connected to a U.S.  trade or
business,  at  the  maximum  tax  rate  for  corporations  or  individuals,   as
applicable.  Amounts withheld will be deemed distributed to the non-U.S.  Person
Securityholders.  Subsequent adoption of Treasury regulations or the issuance of
other  administrative  pronouncements  may require the Partnership Trust Fund to
change its withholding procedures. In determining a holder's withholding status,
the  Partnership  Trust  Fund may rely on IRS Form  W-8BEN,  IRS Form W-9 or the
holder's certification of nonforeign status signed under penalties of perjury.

      To the extent specified in the applicable prospectus supplement,  (i) each
non-U.S.  Person holder might be required to file a U.S. individual or corporate
income tax return (including,  in the case of a corporation,  the branch profits
tax) on its share of the  Partnership  Trust Fund's  income;  (ii) each non-U.S.
Person  holder  must  obtain a taxpayer  identification  number from the IRS and
submit  that  number to the  Partnership  Trust Fund on Form  W-8BEN in order to
assure appropriate crediting of the taxes withheld; and (iii) a non-U.S.  Person
holder  generally would be entitled to file with the IRS a claim for refund with
respect to taxes  withheld by the  Partnership  Trust Fund,  taking the position
that no taxes were due because the  Partnership  Trust Fund was not engaged in a
U.S. trade or business.  Notwithstanding  the foregoing,  interest payments made
(or  accrued) to a  Securityholder  who is a non-U.S.  Person may be  considered
guaranteed payments to the extent such payments are determined without regard to
the  income of the  Partnership  Trust  Fund.  If these  interest  payments  are
properly  characterized  as  guaranteed  payments,  then the interest may not be
considered "portfolio  interest." As a result,  Securityholders who are non-U.S.
Persons may be subject to United States federal income tax and  withholding  tax
at a rate of 30 percent,  unless reduced or eliminated pursuant to an applicable
treaty. In such case, a non-U.S. Person holder would only be entitled to claim a
refund  for that  portion  of the taxes in excess  of the taxes  that  should be
withheld with respect to the guaranteed payments.

      Backup Withholding

      Distributions  made on the  Partnership  Securities  and proceeds from the
sale of the Partnership Securities will be subject to a "backup" withholding tax
of 28% (increasing to 31% after 2010) if, in general,  the Securityholder  fails
to comply with certain identification procedures, unless the holder is an exempt
recipient under applicable provisions of the Code.

      PROSPECTIVE  INVESTORS  SHOULD  CONSULT THEIR TAX ADVISORS  CONCERNING ANY
POSSIBLE  TAX  RETURN  DISCLOSURE  OBLIGATION  WITH  RESPECT  TO THE  SECURITIES
DISCUSSED  HEREIN.  THE FEDERAL TAX DISCUSSIONS SET FORTH ABOVE ARE INCLUDED FOR
GENERAL   INFORMATION   ONLY  AND  MAY  NOT  BE  APPLICABLE   DEPENDING  UPON  A
SECURITYHOLDER'S PARTICULAR TAX SITUATION. PROSPECTIVE PURCHASERS SHOULD CONSULT
THEIR TAX ADVISORS WITH RESPECT TO THE TAX CONSEQUENCES TO THEM OF THE PURCHASE,
OWNERSHIP  AND  DISPOSITION  OF  REMIC  SECURITIES,  GRANTOR  TRUST  SECURITIES,
PARTNERSHIP SECURITIES 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.

                        STATE AND OTHER TAX CONSEQUENCES

      In addition to the federal income tax  consequences  described in "Federal
Income Tax  Consequences,"  potential  investors  should  consider the state and
local tax  consequences of the  acquisition,  ownership,  and disposition of the
Securities  offered hereunder.  State tax 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  should  consult  their own tax advisors with
respect to the various tax consequences of investments in the Securities offered
hereunder.

                              ERISA CONSIDERATIONS

      The Employee Retirement Income Security Act of 1974, as amended ("ERISA" )
and the Code  impose  certain  requirements  on  employee  benefit  plans and on
certain other retirement plans and arrangements, including individual retirement
accounts, individual retirement annuities, Keogh plans and collective investment
funds and separate  accounts in which such plans,  accounts or arrangements  are
invested,  that are  subject  to Title I of ERISA and  Section  4975 of the Code
("Plans")  and on  persons  who are  fiduciaries  with  respect to such Plans in
connection with the investment of Plan assets.  Certain  employee benefit plans,
such as  governmental  plans (as  defined in ERISA  Section  3(32)),  and, if no
election  has been made  under  Section  410(d) of the  Code,  church  plans (as
defined  in  Section  3(33) of ERISA)  are not  subject  to ERISA  requirements.
However,  such  plans  may be  subject  to the  provisions  of other  applicable
federal,  state and local law materially similar to the foregoing  provisions of
ERISA and the Code.  Any such plan which is qualified  and exempt from  taxation
under  Sections  401(a)  and  501(a) of the Code,  however,  is  subject  to the
prohibited transaction rules set forth in Section 503 of the Code.

      ERISA generally  imposes on Plan  fiduciaries  certain  general  fiduciary
requirements, including those of investment prudence and diversification and the
requirement  that a Plan's  investments be made in accordance with the documents
governing  the Plan.  In addition,  ERISA and the Code prohibit a broad range of
transactions  involving assets of a Plan and persons ("Parties in Interest") who
have  certain  specified  relationships  to  the  Plan  unless  a  statutory  or
administrative  exemption  is  available.   Certain  Parties  in  Interest  that
participate in a prohibited  transaction may be subject to an excise tax imposed
pursuant  to Section  4975 of the Code,  unless a  statutory  or  administrative
exemption is available. These prohibited transactions generally are set forth in
Sections 406 and 407 of ERISA and Section 4975 of the Code.

      A Plan's investment in Securities may cause the Mortgage Loans, Contracts,
Unsecured Home  Improvement  Loans and other assets  included in a related Trust
Fund to be  deemed  Plan  assets.  United  States  Department  of Labor  ("DOL")
regulations  Section 2510.3-101 (as modified by Section 3(42) of ERISA) provides
that when a Plan  acquires an equity  interest in an entity,  the Plan's  assets
include  both such  equity  interest  and an  undivided  interest in each of the
underlying assets of the entity,  unless certain  exceptions not applicable here
apply,  or unless  the  equity  participation  in the  entity by  "benefit  plan
investors"  (i.e.,  Plans and any entity whose  underlying  assets are deemed to
include assets of such Plans by reason of such Plan's  investment in the entity)
is not  "significant,"  both as defined therein.  For this purpose,  in general,
equity participation by benefit plan investors will be "significant" on any date
if 25% or more of the value of any Class of equity  interests  in the  entity is
held by benefit  plan  investors.  To the extent the  Securities  are treated as
equity interests for purposes of DOL regulations Section 2510.3-101 (as modified
by  Section  3(42) of  ERISA),  equity  participation  in a Trust  Fund  will be
significant on any date if immediately after the most recent  acquisition of any
Security,  25% or more of any  Class  of  Securities  is  held by  benefit  plan
investors.  With respect to the application of the 25% limit described above, if
a benefit plan investor that is an entity whose underlying  assets are deemed to
include Plan assets, acquires equity interests in the issuing entity, only a pro
rata portion of such equity  interests  will be treated as being held by benefit
plan investors for purposes of DOL regulations  Section  2510.3-101 (as modified
by Section 3(42) of ERISA).

      Any person who has  discretionary  authority  or  control  respecting  the
management or disposition of Plan assets, and any person who provides investment
advice with  respect to such assets for a fee, is a fiduciary  of the  investing
Plan. If the Mortgage Loans,  Contracts,  Unsecured Home  Improvement  Loans and
other assets  included in a Trust Fund  constitute  Plan assets,  then any party
exercising  management or discretionary  control regarding those assets, such as
the Servicer or Master Servicer, may be deemed to be a Plan "fiduciary" and thus
subject to the fiduciary  responsibility  provisions and prohibited  transaction
provisions  of  ERISA  and the Code  with  respect  to the  investing  Plan.  In
addition, if the Mortgage Loans, Contracts, Unsecured Home Improvement Loans and
other assets included in a Trust Fund  constitute  Plan assets,  the purchase of
Securities by a Plan, as well as the operation of the Trust Fund, may constitute
or involve a prohibited transaction under ERISA and the Code.

                                       124



      On  May  14,  1993,  the  DOL  granted  to  NationsBank  Corporation,  the
predecessor  to Bank of America  Corporation,  the  corporate  parent of Banc of
America  Securities  LLC, an  individual  administrative  exemption,  Prohibited
Transaction  Exemption  ("PTE") 93-31, as amended by PTE 97-34,  PTE 2000-58 and
PTE 2002-41 (the  "Exemption"),  which generally exempts from the application of
the prohibited  transaction  provisions of Sections 406(a) and 407 of ERISA, and
the excise taxes  imposed on such  prohibited  transactions  pursuant to Section
4975(a) and (b) of the Code, certain transactions, among others, relating to the
servicing and operation of mortgage pools and the purchase,  sale and holding of
Securities  underwritten by an Underwriter (as  hereinafter  defined),  that (a)
represent  a  beneficial  ownership  interest  in the assets of a Trust Fund and
entitle the holder the pass-through payments of principal, interest and/or other
payments  made  with  respect  to  the  assets  of the  Trust  Fund  or (b)  are
denominated as a debt instrument and represent an interest in a REMIC or certain
other  specified  entities,  provided that certain  conditions  set forth in the
Exemption are satisfied.  For purposes of this Section  "ERISA  Considerations,"
the term "Underwriter"  shall include (a) Bank of America  Corporation,  (b) any
person directly or indirectly, through one or more intermediaries,  controlling,
controlled  by or  under  common  control  with  Bank  of  America  Corporation,
including Banc of America Securities LLC, and (c) any member of the underwriting
syndicate  or  selling  group  of which a  person  described  in (a) or (b) is a
manager or co-manager with respect to a Class of Securities.

      The Exemption sets forth five general  conditions  which must be satisfied
for a transaction  involving the purchase,  sale and holding of Securities to be
eligible for exemptive relief  thereunder.  First, the acquisition of Securities
by a Plan 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
Securities  at the time of  acquisition  by the Plan must be rated in one of the
four highest generic rating  categories by Standard & Poor's,  a division of The
McGraw-Hill Companies, Inc. ("S&P"), Moody's Investors Service, Inc. ("Moody's")
or Fitch Ratings  ("Fitch").  Third,  the Trustee  cannot be an affiliate of any
member of the Restricted Group other than an Underwriter; the "Restricted Group"
consists of the Underwriter,  the Depositor,  the Trustee,  the Master Servicer,
any  Servicer,  any insurer and any obligor with respect to Assets  constituting
more than 5% of the aggregate unamortized principal balance of the Assets in the
related Trust Fund as of the date of initial issuance of the Securities. Fourth,
the  sum  of all  payments  made  to and  retained  by the  Underwriter(s)  must
represent not more than reasonable compensation for underwriting the Securities;
the sum of all payments  made to and retained by the  Depositor  pursuant to the
assignment of the Assets to the related Trust Fund must  represent not more than
the fair market value of such  obligations;  and the sum of all payments made to
and  retained  by  the  Servicer  must   represent  not  more  than   reasonable
compensation  for such  person's  services  under the  applicable  Agreement and
reimbursement  of such person's  reasonable  expenses in  connection  therewith.
Fifth,  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. In addition, the Trust Fund must meet the following  requirements:  (i)
the assets of the Trust Fund must consist solely of assets of the type that have
been included in other investment pools; (ii) securities evidencing interests in
such other  investment  pools  must have been  rated in one of the four  highest
generic rating  categories by S&P,  Moody's or Fitch for at least one year prior
to the Plan's  acquisition of the securities;  and (iii)  securities  evidencing
interests in such other  investment  pools must have been purchased by investors
other than Plans for at least one year  prior to any Plan's  acquisition  of the
Securities.

      A fiduciary of a Plan  contemplating  purchasing a Security  must make its
own determination  that the general conditions set forth above will be satisfied
with  respect to such  Security.  In addition,  any  Securities  representing  a
beneficial  ownership  interest in Unsecured Home Improvement Loans or Revolving
Credit Line Loans will not satisfy the general conditions of the Exemption.

      If the general  conditions of the Exemption are  satisfied,  the Exemption
may provide an exemption from the  restrictions  imposed by Sections  406(a) and
407 of ERISA (as well as the excise taxes imposed by Sections 4975(a) and (b) of
the  Code by  reason  of  Sections  4975(c)(1)(A)  through  (D) of the  Code) in
connection with the direct or indirect sale, exchange,  transfer, holding or the
direct  or  indirect  acquisition  or  disposition  in the  secondary  market of
Securities by Plans.  However, no exemption is provided from the restrictions of
Sections 406(a)(1)(E), 406(a)(2) and 407 of ERISA for the acquisition or holding
of  a  Security  on  behalf  of  an  "Excluded  Plan"  by  any  person  who  has
discretionary  authority or renders investment advice with respect to the assets
of such Excluded  Plan.  For purposes of the  Securities,  an Excluded Plan is a
Plan sponsored by any member of the Restricted Group.

      If certain  specific  conditions of the Exemption are also satisfied,  the
Exemption  may provide an exemption  from the  restrictions  imposed by Sections
406(b)(1) and (b)(2) of ERISA and the taxes imposed by Sections  4975(a)

                                       125



and (b) of the Code by reason of Section 4975(c)(1)(E) of the Code in connection
with (1) the direct or indirect sale,  exchange or transfer of Securities in the
initial  issuance of Securities  between the Depositor or an  Underwriter  and a
Plan when the  person who has  discretionary  authority  or  renders  investment
advice with respect to the investment of Plan assets in the Securities is (a) an
obligor with respect to 5% or less of the fair market value of the Assets or (b)
an  affiliate  of such a person,  (2) the  direct  or  indirect  acquisition  or
disposition in the secondary  market of Securities by a Plan and (3) the holding
of Securities by a Plan.

      Further,  if certain  specific  conditions of the Exemption are satisfied,
the Exemption may provide an exemption from the restrictions imposed by Sections
406(a),  406(b) and 407 of ERISA,  and the taxes imposed by Sections 4975(a) and
(b) of the Code by reason of  Section  4975(c) of the Code for  transactions  in
connection  with the servicing,  management and operation of the Trust Fund. The
Depositor  expects that the specific  conditions of the  Exemption  required for
this  purpose  will be  satisfied  with  respect to the  Securities  so that the
Exemption would provide an exemption from the  restrictions  imposed by Sections
406(a) and (b) of ERISA (as well as the excise taxes imposed by Sections 4975(a)
and (b) of the Code by reason of Section  4975(c) of the Code) for  transactions
in  connection  with the  servicing,  management  and  operation of the Mortgage
Pools, provided that the general conditions of the Exemption are satisfied.

      The Exemption also may provide an exemption from the restrictions  imposed
by Sections 406(a) and 407(a) of ERISA, and the taxes imposed by Section 4975(a)
and (b) of the Code by reason of Sections  4975(c)(1)(A) through (D) of the Code
if such  restrictions  are deemed to otherwise  apply merely because a person is
deemed to be a "party in  interest"  (within  the  meaning of  Section  3(14) of
ERISA) or a "disqualified  person" (within the meaning of Section  4975(e)(2) of
the Code) with respect to an investing  Plan by virtue of providing  services to
the Plan (or by virtue  of  having  certain  specified  relationships  to such a
person) solely as a result of the Plan's ownership of Securities.

      The  Exemption  was  amended by PTE 97-34,  62 Fed.  Reg.  39021 (July 21,
1997),  which,  among other  changes,  permits the  inclusion  of a  pre-funding
account in a trust fund, provided that the following conditions are met: (a) the
pre-funding account may not exceed 25% of the total amount of certificates being
offered; (b) additional obligations purchased generally must meet the same terms
and  conditions  as those of the original  obligations  used to create the trust
fund;  (c) the  transfer  of  additional  obligations  to the trust  during  the
pre-funding period must not result in the certificates  receiving a lower rating
at the termination of the  pre-funding  period than the rating that was obtained
at the  time of the  initial  issuance  of the  certificates;  (d) the  weighted
average  interest rate for all of the obligations in the trust at the end of the
pre-funding period must not be more than 100 basis points less than the weighted
average interest rate for the obligations which were transferred to the trust on
the closing date; (e) the characteristics of the additional  obligations must be
monitored  to confirm  that they are  substantially  similar to those which were
acquired as of the closing date either by a credit support provider or insurance
provider independent of the sponsor or by an independent  accountant retained by
the sponsor that  confirms  such  conformance  in writing;  (f) the  pre-funding
period must be  described  in the  prospectus  or private  placement  memorandum
provided  to  investing  plans;  and  (g) the  trustee  of the  trust  must be a
substantial   financial  institution  or  trust  company  experienced  in  trust
activities and familiar with its duties,  responsibilities  and liabilities as a
fiduciary under ERISA.

      Further,  the pre-funding period must be a period beginning on the closing
date and ending no later than the  earliest  to occur of (x) the date the amount
on deposit in the  pre-funding  account is less than the minimum  dollar  amount
specified in the pooling and servicing agreement; (y) the date on which an event
of default  occurs under the pooling and  servicing  agreement;  or (z) the date
which is the later of three  months or 90 days  after the  closing  date.  It is
expected that the Pre-Funding Account will meet all of these requirements.

      To the extent the  Securities  are not  treated  as equity  interests  for
purposes of DOL regulations  section 2510.3-101 (as modified by Section 3(42) of
ERISA), a Plan's investment in such Securities  ("Non-Equity  Securities") would
not cause the assets  included in a related Trust Fund to be deemed Plan assets.
However,  the Depositor,  the Servicer,  the Trustee,  or Underwriter may be the
sponsor of or investment advisor with respect to one or more Plans. Because such
parties may receive  certain  benefits in connection with the sale of Non-Equity
Securities,  the purchase of Non-Equity  Securities using Plan assets over which
any such parties has investment  authority  might be deemed to be a violation of
the  prohibited  transaction  rules of ERISA and the Code for which no

                                       126



exemption  may be  available.  Accordingly,  Non-Equity  Securities  may  not be
purchased  using the assets of any Plan if any of the  Depositor,  the Servicer,
the Trustee or Underwriter has investment authority with respect to such assets.

      In addition,  certain  affiliates of the Depositor  might be considered or
might become  Parties in Interest  with respect to a Plan.  Also,  any holder of
Securities,  because  of its  activities  or the  activities  of its  respective
affiliates,  may be deemed to be a Party in  Interest  with  respect  to certain
Plans,  including but not limited to Plans  sponsored by such holder.  In either
case,  the  acquisition  or holding of Non-Equity  Securities by or on behalf of
such a  Plan  could  be  considered  to  give  rise  to an  indirect  prohibited
transaction  within the  meaning of ERISA and the Code,  unless it is subject to
one  or  more  statutory  or   administrative   exemptions  such  as  Prohibited
Transaction Class Exemption ("PTCE") 84-14,  which exempts certain  transactions
effected on behalf of a Plan by a "qualified  professional asset manager",  PTCE
90-1,  which exempts certain  transactions  involving  insurance  company pooled
separate accounts, PTCE 91-38, which exempts certain transactions involving bank
collective  investment  funds,  PTCE 95-60,  which exempts certain  transactions
involving  insurance  company  general  accounts,  or PTCE 96-23,  which exempts
certain  transactions  effected on behalf of a Plan by certain  "in-house" asset
managers.  It should be noted, however, that even if the conditions specified in
one or more of these  exemptions are met, the scope of relief  provided by these
exemptions  may not  necessarily  cover  all acts  that  might be  construed  as
prohibited transactions.

      Any Plan fiduciary  which proposes to cause a Plan to purchase  Securities
should consult with its counsel with respect to the potential  applicability  of
ERISA and the Code to such investment,  the availability of the exemptive relief
provided  in  the  Exemption  and  the  potential  applicability  of  any  other
prohibited transaction exemption in connection therewith. In particular,  a Plan
fiduciary which proposes to cause a Plan to purchase  Securities  representing a
beneficial  ownership  interest  in a pool of  single-family  residential  first
mortgage loans, a Plan fiduciary should consider the applicability of PTCE 83-1,
which provides exemptive relief for certain transactions involving mortgage pool
investment  trusts.  The  prospectus  supplement  with  respect  to a Series  of
Securities may contain additional  information  regarding the application of the
Exemption,  PTCE 83-1 or any other  exemption,  with  respect to the  Securities
offered thereby.  In addition,  any Plan fiduciary that proposes to cause a Plan
to purchase Strip Securities should consider the federal income tax consequences
of such investment.  Fiduciaries of plans not subject to ERISA or the Code, such
as  governmental  plans,  should  consider  the  application  of any  applicable
federal,  state or local law materially  similar to the  prohibited  transaction
rules of ERISA or the Code or the fiduciary  provisions of ERISA, as well as the
need for and the availability of exemptive relief under such applicable law.

      Any Plan fiduciary considering whether to purchase a Security on behalf of
a Plan  should  consult  with its counsel  regarding  the  applicability  of the
fiduciary  responsibility and prohibited transaction provisions of ERISA and the
Code to such investment.

      The sale of Securities to a Plan is in no respect a representation  by the
Depositor or the  Underwriter  that this  investment  meets all  relevant  legal
requirements  with respect to investments  by Plans  generally or any particular
Plan,  or that  this  investment  is  appropriate  for  Plans  generally  or any
particular Plan.

                                LEGAL INVESTMENT

      As will be  specified in the  applicable  prospectus  supplement,  certain
Classes of the Securities will  constitute  "mortgage  related  securities " for
purposes of the Secondary  Mortgage  Market  Enhancement Act of 1984, as amended
("SMMEA"),  so long as (i)  they  are  rated  in one of the two  highest  rating
categories  by at  least  one  Rating  Agency  and  (ii)  are  part of a  Series
representing  interests in a Trust Fund consisting of Mortgage Loans  originated
by certain types of originators specified in SMMEA and secured by first liens on
real estate. The appropriate characterization of those Securities not qualifying
as "mortgage related securities" for purposes of SMMEA ("Non-SMMEA  Securities")
under various legal investment  restrictions,  and thus the ability of investors
subject to these  restrictions  to purchase such  Securities,  may be subject to
significant  interpretive  uncertainties.   Accordingly,   all  investors  whose
investment  activities  are subject to legal  investment  laws and  regulations,
regulatory  capital  requirements,  or review by regulatory  authorities  should
consult with their own legal advisors in determining  whether and to what extent
the Non-SMMEA Securities constitute legal investments for them.

      Classes which qualify as "mortgage  related  securities"  will  constitute
legal investments for persons, trusts, corporations, partnerships, associations,
business trusts and business  entities  (including but not limited to depository

                                       127



institutions,  insurance  companies and pension  funds)  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   thereof  constitute  legal  investments  for  such
entities.  Pursuant  to SMMEA,  a number of states  enacted  legislation,  on or
before the  October 3, 1991  cut-off  for such  enactments,  limiting to varying
extents the ability of certain entities (in particular,  insurance companies) to
invest in "mortgage  related  securities"  secured by loans 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.
Pursuant  to Section  347 of the Riegle  Community  Development  and  Regulatory
Improvement  Act of 1994,  which  amended the  definition  of "mortgage  related
security" to include,  in relevant  part,  Securities  satisfying the rating and
qualified  originator   requirements  for  "mortgage  related  securities,"  but
evidencing  interests in a Trust Fund consisting,  in whole or in part, of first
liens on one or more  parcels of real  estate upon which are located one or more
commercial structures, states were authorized to enact legislation, on or before
September 23, 2001,  specifically  referring to Section 347 and  prohibiting  or
restricting the purchase,  holding or investment by state-regulated  entities in
those  types  of  Securities.   Accordingly,  the  investors  affected  by  such
legislation  will be authorized to invest in the Offered  Securities only to the
extent provided in such legislation.

      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 of their assets represented
thereby, federal credit unions may invest in such securities, and national banks
may purchase mortgage related securities for their own account without regard to
the limitations generally applicable to investment securities set forth in 12 U.
S. C.  Section 24  (Seventh),  subject in each case to such  regulations  as the
applicable federal regulatory authority may prescribe.  In this connection,  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 certain general standards in
12 C. F. R.  Section 1.5  concerning  "safety and  soundness"  and  retention of
credit  information),  certain  "Type  IV  securities,"  defined  in 12 C. F. R.
Section 1.2(m) to include certain "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,"  other than stripped mortgage related securities (unless the credit
union  complies  with  the  requirements  of 12  C.F.R.  Section  703.16(e)  for
investing  in  those   securities),   residual  interests  in  mortgage  related
securities and commercial  mortgage  related  securities,  subject to compliance
with general rules governing investment policies and practices;  however, credit
unions  approved  for the  NCUA's  "investment  pilot  program"  under 12 C.F.R.
Section  703.19 may be able to invest in those  prohibited  forms of securities.
The OTS has issued  Thrift  Bulletin  13a  (December 1, 1998),  " Management  of
Interest Rate Risk, Investment Securities, and Derivative Activities" and Thrift
Bulletin 73a  (December  18, 2001),  "Investing  in Complex  Securities,"  which
thrift  institutions  subject to the  jurisdiction  of the OTS  should  consider
before investing in any of the Offered Securities.

      All  depository  institutions  considering  an  investment  in the Offered
Securities  should  review  the  "Supervisory  Policy  Statement  on  Investment
Securities  and  End-User  Derivatives  Activities"  of  the  Federal  Financial
Institutions  Examination  Council,  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. This 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.

      Investors 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 Class of the Offered
Securities,  as certain  Classes may be deemed  unsuitable  investments,  or may
otherwise be restricted,  under those rules, policies, or guidelines (in certain
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 which
may restrict or prohibit investment

                                      128



in securities which are not  "interest-bearing"  or  "income-paying,"  and, with
regard to any Class of Offered Securities issued in book-entry form,  provisions
which may restrict or prohibit  investments  in  securities  which are issued in
book-entry form.

      Except as to the  status of  certain  Classes  of  Offered  Securities  as
"mortgage  related  securities,"  no  representations  are made as to the proper
characterization  of the  Offered  Securities  for  legal  investment  purposes,
financial  institution  regulatory  purposes,  or other  purposes,  or as to the
ability of  particular  investors  to  purchase  any  Offered  Securities  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 Securities) may adversely
affect the liquidity of the Offered Securities.

      Accordingly,  all investors  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 the  Offered  Securities  of any Class
constitute  legal  investments  or are subject to  investment,  capital or other
restrictions  and,  if  applicable,  whether  SMMEA has been  overridden  in any
jurisdiction relevant to such investor.

                             METHODS OF DISTRIBUTION

      The Securities  offered hereby and by the  supplements to this  prospectus
will be offered in Series.  The  distribution  of the Securities 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 so
specified  in  the  related  prospectus  supplement,   the  Securities  will  be
distributed  in a  firm  commitment  underwriting,  subject  to  the  terms  and
conditions of the  underwriting  agreement,  by Banc of America  Securities  LLC
("Banc of America Securities") acting as underwriter with other underwriters, if
any, named therein.  In such event,  the prospectus  supplement may also specify
that the underwriters  will not be obligated to pay for any Securities agreed to
be purchased by  purchasers  pursuant to purchase  agreements  acceptable to the
Depositor.  In  connection  with the sale of the  Securities,  underwriters  may
receive  compensation from the Depositor or from purchasers of the Securities in
the form of discounts,  concessions or  commissions.  The prospectus  supplement
will describe any such compensation paid by the Depositor.

      Alternatively,  the prospectus  supplement may specify that the Securities
will be  distributed  by Banc of America  Securities  acting as agent or in some
cases as principal with respect to Securities which it has previously  purchased
or agreed to purchase.  If Banc of America  Securities acts as agent in the sale
of Securities, Banc of America Securities will receive a selling commission with
respect to each Series of Securities,  depending on market conditions, expressed
as a percentage of the aggregate  principal  balance of the related Assets as of
the Cut-off Date.  The exact  percentage  for each Series of Securities  will be
disclosed  in the  related  prospectus  supplement.  To the extent  that Banc of
America Securities elects to purchase  Securities as principal,  Banc of America
Securities may realize  losses or profits based upon the difference  between its
purchase price and the sales price.

      In addition, the prospectus supplement may specify that the Securities may
be offered by direct placements by the Depositor with investors,  in which event
the  Depositor  will be an  underwriter  with respect to the  Securities,  or by
inclusion  as  underlying  securities  backing  another  series of  asset-backed
securities  issued by an entity of which the  Depositor  or an  affiliate of the
Depositor  may act as the  depositor.  In the  event  that the  Depositor  or an
affiliate of the Depositor acts as depositor with respect to the other series of
asset-backed  securities,  the Depositor or its affiliate will be an underwriter
with respect to the underlying securities.

      The  prospectus  supplement  with respect to any Series offered other than
through  underwriters  will  contain  information  regarding  the nature of such
offering  and any  agreements  to be entered  into  between  the  Depositor  and
purchasers of Securities of such Series.

      The  Depositor  will   indemnify  Banc  of  America   Securities  and  any
underwriters against certain civil liabilities,  including liabilities under the
Securities  Act of  1933,  or  will  contribute  to  payments  Banc  of  America
Securities and any underwriters may be required to make in respect thereof.

                                      129



      In the ordinary  course of business,  Banc of America  Securities  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 such mortgage  loans or interests  therein,  including
the Securities.

      The Depositor  anticipates  that the Securities  will be sold primarily to
institutional  investors.  Purchasers of  Securities,  including  dealers,  may,
depending on the facts and  circumstances of such purchases,  be  "underwriters"
within the meaning of the Securities Act of 1933 in connection with reoffers and
sales by them of  Securities.  Securityholders  should  consult with their legal
advisors in this regard prior to any such reoffer or sale.

      As to each Series of  Securities,  only those  Classes rated in one of the
four highest rating categories by any Rating Agency will be offered hereby.  Any
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.

                                  LEGAL MATTERS

      The legality of,  including the federal income tax matters  related to the
Securities  of a Series,  will be passed upon for the  Depositor by  Cadwalader,
Wickersham & Taft LLP, New York,  New York or Hunton & Williams LLP,  Charlotte,
North Carolina.

                              FINANCIAL INFORMATION

      A new Trust Fund will be formed with respect to each Series of  Securities
and no Trust Fund will engage in any business  activities  or have any assets or
obligations  prior  to  the  issuance  of  the  related  Series  of  Securities.
Accordingly,  no  financial  statements  with  respect to any Trust Fund will be
included in this prospectus or in the related prospectus supplement.

                                     RATING

      It is a condition to the issuance of any Class of Offered  Securities that
they shall have been rated not lower than investment  grade,  that is, in one of
the four  highest  rating  categories,  by at least  one  nationally  recognized
statistical rating organization ("Rating Agency").

      Ratings on mortgage  pass-through  securities  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 such  securities,  the nature of the underlying  assets and the
credit  quality  of the  guarantor,  if any.  Ratings on  mortgage  pass-through
securities and other asset-backed  securities do not represent any assessment of
the  likelihood of principal  prepayments by borrowers or of the degree by which
such 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  securities  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.

                           REPORTS TO SECURITYHOLDERS

      The Trustee will prepare and forward to the Securityholders of each Series
statements  containing  information  with  respect  to  principal  and  interest
payments and the related  Trust Fund,  as described  under  "Description  of the
Securities--Reports  to  Securityholders."  Copies of these  statements  will be
filed   with   the   Commission    through   its   EDGAR   system   located   at
"http://www.sec.gov"  under the name of the Issuing  Entity as an exhibit to the
Issuing  Entity's monthly  distribution  reports on Form 10-D for each Series of
Securities  for so  long as the  Issuing  Entity  is  subject  to the  reporting
requirement  of the  Securities  Exchange Act of 1934, as amended.  In addition,
each party to the servicing  function for a Series of Securities  (generally the
Trustee and the Servicer (and any Master  Servicer)) will furnish to the Trustee
or Master Servicer,  as applicable,  the compliance  statements,  Assessments of
Compliance  and  Attestation   Reports   detailed  under   "Description  of  the
Agreements--Material   Terms  of  the  Pooling  and  Servicing   Agreements  and
Underlying Servicing Agreements--Evidence as to

                                      130



Compliance."  Copies of these  statements  and  reports  will be filed  with the
Commission  under the name of the  Issuing  Entity as an exhibit to the  Issuing
Entity's annual statement on Form 10-K for each Series of Securities.

                       WHERE YOU CAN FIND MORE INFORMATION

      The  Depositor   filed  a  registration   statement   (the   "Registration
Statement")  relating  to  the  Securities  with  the  Securities  and  Exchange
Commission  (the  "Commission").  This  prospectus  is part of the  Registration
Statement, but the Registration Statement includes additional information.

      Copies of the Registration Statement and any other materials the Depositor
files with the Commission,  including  distribution reports on Form 10-D, annual
reports  on Form  10-K,  current  reports  on Form 8-K and  amendments  to these
reports  (collectively,  "Periodic  Reports")  may be  read  and  copied  at the
Commission's Public Reference Room at 100 F Street N.E., Washington, D.C. 20549.
Information  concerning the operation of the Commission's  Public Reference Room
may be obtained by calling the Commission at (800) SEC-0330. The Commission also
maintains a site on the World Wide Web at  "http://www.sec.gov" at which you can
view and download copies of reports,  proxy and information statements and other
information  filed  electronically  through the EDGAR system.  The Depositor has
filed the Registration Statement, including all exhibits, and will file Periodic
Reports  through  the  EDGAR  system  and  therefore  such  materials  should be
available by logging onto the  Commission's  Web site.  Copies of any  documents
incorporated to this prospectus by reference will be provided at no cost to each
person,  including any beneficial  owner, to whom a prospectus is delivered upon
written or oral request directed to Asset Backed Funding Corporation,  214 North
Tryon Street, Charlotte, North Carolina 28255, telephone number (704) 386-2400.

      Copies of filed Periodic  Reports  relating to an Issuing Entity will also
be available on the applicable  Trustee's website on the same day they are filed
through the EDGAR system as described under "Reports to  Certificateholders"  or
"Reports  to  Noteholders,"  as the  case  may  be,  in the  related  prospectus
supplement.

                INCORPORATION OF CERTAIN INFORMATION BY REFERENCE

      The  Commission   allows  the  Depositor  to  "incorporate  by  reference"
information  it files with the  Commission,  which means that the  Depositor can
disclose important  information to you by referring you to those documents.  The
information  incorporated  by  reference  is  considered  to  be  part  of  this
prospectus.  Information that the Depositor files later with the Commission will
automatically  update the  information  in this  prospectus.  In all cases,  you
should rely on the later  information  rather than on any different  information
included in this  prospectus  or the  accompanying  prospectus  supplement.  The
Depositor  incorporates by reference any future monthly  distribution reports on
Form  10-D and any  current  reports  on Form 8-K  filed by or on  behalf of the
Issuing  Entity until the  termination  of the offering of the related Series of
Securities.

      Copies of any documents  incorporated to this prospectus by reference will
be provided at no cost to each person, including any beneficial owner, to whom a
prospectus  is delivered  upon written or oral request  directed to Asset Backed
Funding Corporation,  214 North Tryon Street,  Charlotte,  North Carolina 28255,
telephone number (704) 386-2400.
