         This POOLING AND SERVICING AGREEMENT, dated as of November 1, 2003 (the
"Agreement"), by and among SEQUOIA RESIDENTIAL FUNDING, INC., a Delaware
corporation, as depositor (the "Depositor"), HSBC Bank USA, a New York banking
corporation, as trustee (the "Trustee"), and WELLS FARGO BANK MINNESOTA,
NATIONAL ASSOCIATION, in its dual capacities as master servicer (the "Master
Servicer") and securities administrator (the "Securities Administrator") and
acknowledged by RWT HOLDINGS, INC., a Delaware corporation, as seller (the
"Seller"), for purposes of Section 2.04.

                              PRELIMINARY STATEMENT

         The Depositor has acquired the Initial Mortgage Loans from the Seller
and at the Closing Date is the owner of the Initial Mortgage Loans and the other
property being conveyed by the Depositor to the Trustee hereunder for inclusion
in the Trust Fund. On the Closing Date, the Depositor will acquire the
Certificates from the Trustee as consideration for the Depositor's transfer to
the Trust Fund of the Initial Mortgage Loans, an initial deposit to each
Pre-Funding Account of the Original Pre-Funded Amount with respect to the
related Mortgage Pool, an initial deposit to the Capitalized Interest Account in
an amount sufficient to satisfy the aggregate Capitalized Interest Requirement
on the Certificates during the Pre-Funding Period, and the other property
constituting the Trust Fund. The Depositor has duly authorized the execution and
delivery of this Agreement to provide for the conveyance to the Trustee of the
Mortgage Loans and the other property constituting the Trust Fund. All covenants
and agreements made by the Seller in the Mortgage Loan Purchase and Sale
Agreement and in this Agreement and by the Depositor, the Master Servicer, the
Securities Administrator and the Trustee herein, with respect to the Mortgage
Loans and the other property constituting the Trust Fund, are for the benefit of
the Holders from time to time of the Certificates. The Depositor, the Trustee,
the Master Servicer and the Securities Administrator are entering into this
Agreement, and the Trustee is accepting the Trust Fund created hereby, for good
and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged.

         As provided herein, the Trustee shall elect that the Trust Fund
(exclusive of the Additional Collateral, the assets held in the Reserve Fund,
the Pre-Funding Accounts and the Capitalized Interest Account) be treated for
federal income tax purposes as comprising three real estate mortgage investment
conduits (each, a "REMIC" or, in the alternative, the "Lower-Tier REMIC," the
"Middle-Tier REMIC," and the "Upper-Tier REMIC"). Each Certificate, other than
the Class A-R and Class LT-R Certificate, is hereby designated as a regular
interest in the Upper-Tier REMIC, as described herein. In addition, each of the
LIBOR Certificates represents the right to receive payments in respect of Net
WAC Shortfalls from the Reserve Fund as provided in Section 5.02 and Section
5.06. The owners of the Interest-Only Certificates beneficially own the Reserve
Fund. The Class A-R Certificate is hereby designated as the sole class of
residual interest in the Upper-Tier REMIC. The Class LT-R Certificate evidences
ownership of the sole class of residual interest in the Middle-Tier REMIC (the
"MT-R Interest") and the sole class of residual interest in the Lower-Tier REMIC
(the "LT-R Interest").

         The Lower-Tier REMIC shall hold as its assets all property of the Trust
Fund other than the Additional Collateral, the assets held in the Reserve Fund,
the Pre-Funding Accounts and the Capitalized Interest Account, and the interests
in any REMIC formed hereby. Each Lower-Tier Interest other than the LT-R
Interest is hereby designated as a regular interest in the Lower-Tier REMIC and
the LT-R Interest is hereby designated as the sole Class of residual interest in
the



Lower-Tier REMIC. The Middle-Tier REMIC shall hold as its assets the Lower-Tier
Interests other than the LT-R Interest. Each Middle-Tier Interest other than the
MT-R Interest is hereby designated as a regular interest in the Middle-Tier
REMIC and the MT-R Interest is hereby designated as the sole Class of residual
interest in the Middle-Tier REMIC. The Upper-Tier REMIC shall hold as its assets
the Middle-Tier Interests other than the MT-R Interests.

         THE LOWER-TIER REMIC.

         The following table specifies the Class designation, interest rate, and
initial Class Principal Amount for each Class of Lower-Tier Interests:

- ----------
     (1) The interest rate with respect to any Distribution Date (and the
         related Accrual Period) for these Lower-Tier Interests will be a per
         annum rate equal to the Pool 1 Net WAC.

     (2) The interest rate with respect to any Distribution Date (and the
         related Accrual Period) for these Lower-Tier Interests will be a per
         annum rate equal to the Pool 2 Net WAC.

     (3) The LT-R Interest is the sole class of residual interests in the
         Lower-Tier REMIC. It does not have a principal balance and does not
         bear interest.

         On each Distribution Date, the Available Distribution Amount for each
Mortgage Pool distributable as interest shall be distributed as interest with
respect to the Lower-Tier Interests based on the interest rates described above.
On each Distribution Date, Interest Shortfalls attributable to any Mortgage Pool
shall be allocated among the related Lower-Tier Interests based on the relative
amounts of interest otherwise accrued for the related Accrual Period on each
such Lower-Tier Interest.

         On each Distribution Date, the remaining Available Distribution Amount
for each Mortgage Pool shall be distributed as principal on the Lower-Tier
Interests as follows:

                  (i)      First, to the LT-Pool 1-PSA Interest until the Class
                           Principal Amount of such Lower-Tier Interest equals
                           one percent of the Pool Subordinate Amount for Pool 1
                           for the next succeeding Distribution Date;

                  (ii)     Second, to the LT-Pool 2-PSA Interest until the Class
                           Principal Amount of such Lower-Tier Interest equals
                           one percent of the Pool Subordinate Amount for Pool 2
                           for the next succeeding Distribution Date;

                  (iii)    Third, to the LT-Pool 1-PSA or to the LT-Pool 2-PSA
                           Interests until the ratio of the Class Principal
                           Amount of the LT-Pool 1-PSA Interest to the Class
                           Principal Amount of the LT-Pool 2 PSA Interest equals
                           the ratio of the Pool 1 Subordinate Amount to the
                           Pool 2 Subordinate Amount;

                  (iv)     Fourth, to the Lower-Tier Interests other than those
                           having "PSA" in their class designation as follows:

                           a. To the LT-Pool 1 and LT1-A-1 through LT42-A-1
                              Interests until the aggregate of their Class
                              Principal Amounts equals the difference between
                              (a) the Aggregate Stated Principal Balance of the
                              Pool 1 Mortgage Loans, minus, (b) the Class
                              Principal Amount of the LT-Pool 1-PSA Interest on
                              such Distribution Date, taking into account the
                              distributions under priorities (i) through (iii)
                              above, sequentially in the following order:

                                       4



                                  i.  First, to the extent of principal
                                      distributions on the Class A-1
                                      Certificates on such Distribution Date, to
                                      the Lower-Tier Interests in REMIC 1 having
                                      "A-1" in their Class designation, until
                                      the aggregate of the Class Principal
                                      Amounts of such Lower-Tier Interests
                                      equals the Class Principal Amount of the
                                      Class A-1 Certificate, in ascending order
                                      of their numerical designation until the
                                      Class Principal Amount of each such
                                      Lower-Tier Interest is reduced to zero;
                                      and

                                  ii. Second, to the LT-Pool 1 Interest until
                                      its Class Principal Amount is reduced to
                                      zero;

                           b. To the LT-Pool 2 and LT1-A-2 through LT42-A-2
                              Interests until the aggregate of their Class
                              Principal Amounts equals the difference between
                              (a) the Aggregate Stated Principal Balance of the
                              Pool 2 Mortgage Loans, minus, (b) the Class
                              Principal Amount of the LT-Pool 2-PSA Interest on
                              such Distribution Date, taking into account the
                              distributions under priorities (i) through (iii)
                              above, sequentially in the following order:

                                  i.  First, to the extent of principal
                                      distributions on the Class A-2
                                      Certificates on such Distribution Date, to
                                      the Lower-Tier Interests in REMIC 1 having
                                      "A-2" in their Class designation, until
                                      the aggregate of the Class Principal
                                      Amounts of such Lower-Tier Interests
                                      equals the Class Principal Amount of the
                                      Class A-2 Certificate, in ascending order
                                      of their numerical designation until the
                                      Class Principal Amount of each such
                                      Lower-Tier Interest is reduced to zero;
                                      and

                                  ii. Second, to the LT-Pool 2 Interest until
                                      its Class Principal Amount is reduced to
                                      zero.

         On each Distribution Date, Realized Losses attributable to principal,
with respect to any Mortgage Pool shall each be allocated among the Lower-Tier
Interests in the same manner that principal is distributed among such Lower-Tier
Interests.

(1)  The interest rate with respect to any Distribution Date (and the related
     Accrual Period) for the Class MT-A1 Interests is the per annum rate equal
     to the least of (i) One-Month LIBOR plus 0.32%, (ii) the Pool 1 Net WAC and
     (iii) 11.50%; provided, however, if the Mortgage Loans and related property
     are not purchased pursuant to Section 7.01(b) on the Initial Optional
     Purchase Date, then with respect to each subsequent Distribution Date the
     per annum rate calculated pursuant to clause (i) above with respect to the
     Class MT-A1 Interests will be LIBOR plus 0.64%.

(2)  The Class MT-Pool 1-NAS Component is an interest only component. With
     respect to any Distribution Date (and the related Accrual Period), the
     Class MT- Pool 1-NAS Component is entitled to receive a specified portion
     of the interest accrued on each of Lower-Tier Interests LT1-A-1 through
     LT42-A-1 for the specific Distribution Dates listed in the schedule set
     forth below, at a rate equal to the lesser of (i) 0.80% and (ii) the
     excess, if any, of the Pool 1 Net WAC for such Distribution Date over the
     Certificate Interest Rate for the Class A-1 Certificates for such
     Distribution Date (multiplied by a fraction, the numerator of which is 25
     and the denominator of which is 30 for the first Distribution Date only).

(6)     The Class MT-Pool 2-Companion Component is an interest only component.
     With respect to any Distribution Date (and the related Accrual Period), the
     Class MT-Pool 2-Companion Component is entitled to receive a specified
     portion of the interest accrued on each of Lower-Tier Interests LT-1-A-2
     through LT42-A-2, in each case, at a rate equal to the excess, if any, of
     (i) the Pool 2 Net WAC for such Distribution Date over (ii) the sum of the

     Interest, 0.80%.

(7)     With respect to any Distribution Date (and the related Accrual Period),
     these Interests will bear interest at a per annum rate equal to the
     Subordinate Net WAC, which is a weighted average rate based on the rate
     applicable to the LT-Pool 1-PSA interest and the LT-Pool 2-PSA Interest.

(8)     The interest rate with respect to any Distribution Date (and the related
     Accrual Period) for the MT-AR Interest is a per annum rate equal to the

     Middle-Tier REMIC. It does not have a principal balance and does not bear
     interest.

     On each Distribution Date, the Securities Administrator, as Paying Agent,
shall distribute interest and principal on, and shall allocate Realized Losses
among, the Middle-Tier Interests in the same manner that such amounts are
distributed on and such losses are allocated among the Corresponding Classes of
Certificates.

the amount of the monthly payment due on such Mortgage Loan.

         Securities Administrator: Wells Fargo Bank Minnesota, National
Association, not in its individual capacity but solely as Securities
Administrator, or any successor in interest, or if any

                                       38

         Senior Percentage: Except as provided in this definition, with respect
to any Distribution Date and Mortgage Pool before December 2013, 100%. The
Senior Percentage for any Distribution Date occurring (i) before the
Distribution Date in December 2013 but in or after December 2006 on which the
Two Times Test is satisfied, or (ii) in or after December 2013, is the Pro Rata
Senior Percentage. If the Two Times Test is satisfied with respect to any

Percentage is the Pro Rata Senior Percentage plus 50% of an amount equal to 100%
minus the related Pro Rata Senior Percentage. With respect to any Distribution

December 2013 through November 2014, the Senior Percentage plus 70% of the
Subordinate Percentage for that Distribution Date; (ii) from December 2014
through November 2015, the Senior Percentage plus 60% of the Subordinate
Percentage for that Distribution Date; (iii) from December 2015 through November
2016, the Senior Percentage plus 40% of the Subordinate Percentage for that
Distribution Date; (iv) from December 2016 through November 2017, the Senior
Percentage plus 20% of the Subordinate Percentage for that Distribution Date;
and (v) from and after December 2017, the related Senior Percentage for that
Distribution Date; provided, however, that there shall be no reduction in the
Senior Prepayment Percentage unless both Step Down Conditions are satisfied; and
provided, further, that if on any such Distribution Date the Pro Rata Senior
Percentage exceeds the initial Pro Rata Senior Percentage, the Senior Prepayment
Percentage for that Distribution Date shall again equal 100%.

         Notwithstanding the above, if on any Distribution Date the Two Times
Test is satisfied, the Senior Prepayment Percentage with respect to any Mortgage
Pool shall equal the Senior Percentage for such Distribution Date. In addition,
if on any Distribution Date the allocation to the Senior Certificates then
entitled to distributions of principal of full and partial principal prepayments
and other amounts in the percentage required above would reduce the sum of the
Class Principal Amounts of those Certificates to below zero, the related Senior
Prepayment Percentage for such Distribution Date shall be limited to the
percentage necessary to reduce that Class Principal Amount to zero.

                  (2)      with respect to each Mortgage Loan which became a
         Liquidated Mortgage Loan during the related Prepayment Period, the
         lesser of

                           (x)      the related Senior Prepayment Percentage of
                  the Stated Principal Balance of that Mortgage Loan and

                           (y)      Net Liquidation Proceeds allocable to
                  principal received with respect to that Mortgage Loan.

                  (3)      the related Senior Prepayment Percentage of the
         amounts described in clauses (b), (c), (d) and (g) of the definition of
         "Principal Distribution Amount" for that Mortgage Pool;

provided, however, that on any Distribution Date after a Senior Termination
Date, the Senior Principal Distribution Amount for the remaining Certificate
Group will be calculated pursuant to the above formula based on all Mortgage
Loans rather than the Mortgage Loans in the related Mortgage Pool only.

         Senior Termination Date: For each Certificate Group, the Distribution
Date when the aggregate of the Class Certificate Principal Balances of that
Group has been reduced to zero.

         Servicers: Each Servicer under a Servicing Agreement.

Distribution Date, the rate specified in the related Servicing Agreement.

         Servicing Officer: Any officer of the Servicers involved in, or
responsible for, the administration and servicing of the Mortgage Loans whose
name and facsimile signature appear on a list of servicing officers furnished to
the Master Servicer by the Servicers on the Closing Date pursuant to the
Servicing Agreements, as such list may from time to time be amended.

         Six-Month LIBOR: With respect to the first Accrual Period, the Initial
Six-Month LIBOR Rate. With respect to each subsequent Accrual Period, a per
annum rate determined on the immediately preceding LIBOR Determination Date for
the Class A-2 Certificates in the following manner by the Securities
Administrator on the basis of the "Interest Settlement Rate" set by the BBA for
six-month United States dollar deposits, as such rates appear on the Telerate
Page 3750, as of 11:00 a.m. (London time) on such LIBOR Determination Date.

         (a)      If on such a LIBOR Determination Date, the BBA's Interest
Settlement Rate does not appear on the Telerate Page 3750 as of 11:00 a.m.
(London time), or if the Telerate Page 3750 is not available on such date, the
Securities Administrator will obtain such rate from Reuters' "page LIBOR 01" or
Bloomberg's page "BBAM." If such rate is not published for such LIBOR
Determination Date, Six-Month LIBOR for such date will be the most recently
published Interest Settlement Rate. In the event that the BBA no longer sets an
Interest Settlement Rate, the Securities Administrator will designate an
alternative index that has performed, or that the Securities Administrator
expects to perform, in a manner substantially similar to the BBA's Interest
Settlement Rate. The Securities Administrator will select a particular index as
the alternative index only if it receives an Opinion of Counsel, which opinion
shall be an expense reimbursed from the Distribution Account, that the selection
of such index will not cause any of the REMICs to lose their classification as
REMICs for federal income tax purposes.

         (b)      The establishment of Six-Month LIBOR by the Securities
Administrator and the Securities Administrator's subsequent calculation of the
Certificate Interest Rate applicable to the Class A-2 Certificates for the
relevant Accrual Period, in the absence of manifest error, will be final and
binding.

         Six-Month LIBOR Loan: Each Mortgage Loan bearing a Mortgage Rate that
adjusts in accordance with LIBOR for six-month U.S. dollar deposits.

         Startup Day: The day designated as such pursuant to Section 10.01(b)

in the amortization schedule at the time relating thereto (before any adjustment
to such amortization schedule by reason of any moratorium or similar waiver or
grace period) after giving effect to any previous partial Principal Prepayments
and Liquidation Proceeds allocable to principal (other than with respect to any
Liquidated Mortgage Loan) and to the payment of principal due on such Due Date
and irrespective of any delinquency in payment by the related Mortgagor.

         Step Down Conditions: As of the first Distribution Date as to which any

Classes of Subordinate Certificates on such Distribution Date, does not equal or
exceed 50% and (ii) cumulative Realized Losses with respect to the Mortgage
Loans do not exceed (a) with respect to each Distribution Date from December
2013 through November 2014, 30% of the Original Subordinate Principal Amount,
(b) with respect to each Distribution Date from December 2014 through November
2015, 35% of the Original

                                       41

December 2015 through November 2016, 40% of the Original Subordinate Principal

                           any Principal Transfer Amount paid from the Available
                  Distribution Amount of the Related Certificate Group to an
                  Undercollateralized Group; and

                           the amount of principal distributions made to the
                  Senior Certificates pursuant to Section 5.02(k).

provided, however, that on any Distribution Date after a Senior Termination Date
has occurred with respect to a Mortgage Pool, the Subordinate Principal
Distribution Amount will not be calculated with respect to a Mortgage Pool, but
instead will equal the amount calculated as above based on a Subordinate
Percentage or Subordinate Prepayment Percentage, as applicable, for the
Subordinate Certificates for such Distribution Date with respect to all of the
Mortgage Loans.

after the execution and delivery hereof, but in any case within 180 days of the
Closing Date.

lieu of delivering the above documents, herewith delivers to the Trustee, or to
the related Custodian on behalf of the Trustee, an Officer's Certificate which
shall include a statement to the effect that all amounts received in connection
with such prepayment that are required to be deposited in the Distribution
Account pursuant to Section 4.01 have been so deposited. All original documents
that are not delivered to the Trustee or the related Custodian on behalf of the
Trustee shall be held by the Master Servicer or the applicable Servicer in trust
for the benefit of the Trustee and the Certificateholders.

         (e)      The requirements set forth in paragraphs (b), (c) and (d) of
this Section 2.01 shall equally apply upon the transfer and assignment to the

references therein to "Initial Mortgage Loans" shall be replaced by "Subsequent
Mortgage Loans" and references to "Cut-off Date" and "Closing Date" shall be
replaced by "Subsequent Cut-off Date" and "Subsequent Transfer Date,"

documents set forth in Section 2.01 have been received and appear on their face
to conform with the requirements set forth in Section 4A and 4B of the related

assumption by the Trust Fund, the Trustee, any Custodian or the
Certificateholders of any unsatisfied duty, claim or other liability on any
Initial Mortgage Loan or to any Mortgagor.

         (d)      Each of the parties hereto acknowledges that the Custodians

Subsequent Transfer Date, the Depositor shall be required to deliver to the
Trustee the related Acknowledgements, together with the underlying Purchase
Agreement and Servicing Agreements related to the Subsequent Mortgage Loans,
unless such documents were previously delivered to the Trustee on the Closing

         that includes a description of the collateral covering the Mortgage
         Loans other than a financing statement relating to the security
         interest granted to the Trustee hereunder or that has been terminated.
         The Depositor is not aware of any judgment or tax lien filings against
         the Depositor;

                  (x)      None of the Mortgage Loans have any marks or
         notations indicating that such Mortgage Loans have been pledged,
         assigned or otherwise conveyed to any Person other than the Trustee;
         and

                  (xi)     The Depositor has received all consents and approvals
         required by the terms of the Mortgage Loans to convey the Mortgage
         Loans hereunder to the Trustee.

         The foregoing representations made in this Section 2.03 shall survive
the termination of this Agreement and shall not be waived by any party hereto

         Section 2.04 Discovery of Breach; Repurchase or Substitution of
                      Mortgage Loans.

         (a)      Pursuant to Sections 2(b) and 2(d) of the Mortgage Loan
Purchase and Sale Agreement, the Seller has made certain representations and
warranties as to the characteristics of the Initial Mortgage Loans as of the
Closing Date (and will be deemed to have made the same representations and
warranties with respect to the Subsequent Mortgage Loan as of the applicable
Subsequent Transfer Date). The Depositor, for the benefit of the Trustee and the

                                       52



Certificateholders hereby assigns any such rights against the Seller to the
Trustee and the Seller acknowledges that it has agreed to comply with the
provisions of this Section 2.04 in respect of a breach of any of such
representations and warranties. With respect to the representations and
warranties made pursuant to Section 2(b) of the Mortgage Loan Purchase and Sale
Agreement in clauses (I)(xvii) and (II)(xix) of Schedule A thereto, to the
extent that the representations and warranties contained in such clauses are
made to the best of the Seller's knowledge or as to which the Seller has no
knowledge, if it is discovered by the Depositor, the Seller, the Servicer or the
Trustee that the substance of such representation and warranty is inaccurate and
such inaccuracy materially and adversely affects the value of the related
Mortgage Loan then, notwithstanding the Seller's lack of knowledge with respect
to the substance of such representation and warranty being inaccurate at the
time the representation or warranty was made, such inaccuracy shall be deemed a
breach of the applicable representation or warranty.

         It is understood and agreed that such representations and warranties
set forth in Section 2(b) and 2(d) of the Mortgage Loan Purchase and Sale
Agreement shall survive delivery of the Trustee Mortgage Files and the
Assignment of Mortgage of each Mortgage Loan to the Trustee and shall continue
throughout the term of this Agreement. Upon discovery by the Depositor or
receipt of written notice of any materially defective document in, or, following
the date of delivery to the Trustee of each Custodian's Final Trust Receipt as
required under the related Custody Agreement, that a document is missing from, a
related Trustee Mortgage File, or discovery by the Depositor, the Seller of the
breach by the Seller of any representation or warranty under the Mortgage Loan
Purchase and Sale Agreement in respect of any Mortgage Loan which materially
adversely affects the value of that Mortgage Loan or the interest therein of the
Certificateholders (a "Defective Mortgage Loan") (each of such parties hereby
agreeing to give written notice thereof to the Trustee and the other of such
parties), the Trustee, or its designee, shall promptly notify the Depositor in
writing of such defective or missing document or breach and request that the
Depositor deliver such missing document or cure or cause the cure of such defect
or breach within 90 days from the date that the Depositor discovered or was
notified of such missing document, defect or breach, and if the Depositor does
not deliver such missing document or cure such defect or breach in all material
respects during such period, the Trustee shall enforce the Seller's obligation
under the Mortgage Loan Purchase and Sale Agreement and cause the Seller to
repurchase that Mortgage Loan from the Trust Fund at the Purchase Price on or
prior to the Determination Date following the expiration of such 90-day period
(subject to Section 2.04(b) below); provided, however, that, in connection with
any such breach that could not reasonably have been cured within such 90-day
period, if the Seller shall have commenced to cure such breach within such
90-day period, the Seller shall be permitted to proceed thereafter diligently
and expeditiously to cure the same within an additional 90-day period. The
Purchase Price for the repurchased Mortgage Loan shall be deposited in the
related Distribution Account, and the Trustee, or its designee, upon receipt of
written certification from the Securities Administrator of such deposit, shall
release to the Seller, the related Trustee Mortgage File and shall execute and
deliver such instruments of transfer or assignment, in each case without
recourse, representation or warranties, as either party shall furnish to it and
as shall be necessary to vest in such party any Mortgage Loan released pursuant
hereto and the Trustee, or its designee, shall have no further responsibility
with regard to such Trustee Mortgage File (it being understood that the Trustee
shall have no responsibility for determining the sufficiency of such assignment
for its intended purpose). In lieu of repurchasing any such Mortgage Loan as
provided above, either party may cause such Mortgage Loan to be removed from the
Trust Fund

                                       53



(in which case it shall become a Deleted Mortgage Loan) and substitute one or
more Replacement Mortgage Loans in the manner and subject to the limitations set
forth in Section 2.04(b) below. It is understood and agreed that the obligation
of the Seller to cure or to repurchase (or to substitute for) any Mortgage Loan
as to which a document is missing, a material defect in a constituent document
exists or as to which such a breach has occurred and is continuing shall
constitute the sole remedy against the such party respecting such omission,
defect or breach available to the Trustee on behalf of the Certificateholders.

         (b)      Any substitution of Replacement Mortgage Loans for Deleted
Mortgage Loans made pursuant to Section 2.04(a) above must be effected prior to
the last Business Day that is within two years after the Closing Date. As to any
Deleted Mortgage Loan for which the Seller substitutes a Replacement Mortgage
Loan or Loans, such substitution shall be effected by delivering to the related
Custodian, on behalf of the Trustee, for such Replacement Mortgage Loan or
Loans, the related Mortgage Note, the related Mortgage, the related Assignment
to the Trustee, and such other documents and agreements, with all necessary
endorsements thereon, together with an Officers' Certificate stating that each
such Replacement Mortgage Loan satisfies the definition thereof and specifying
the Substitution Amount (as described below), if any, in connection with such
substitution. Such Custodian shall acknowledge receipt for such Replacement
Mortgage Loan and, within 45 days thereafter, shall review such Mortgage
Documents as specified in the related Custody Agreement and deliver to the
Trustee and the Depositor, with respect to such Replacement Mortgage Loans, a
certification substantially in the form of a revised Trust Receipt, with any
exceptions noted thereon. Within one year of the date of substitution, the
related Custodian shall deliver to the Trustee and the Depositor a certification
substantially in the form of a revised Final Trust Receipt, with respect to such
Replacement Mortgage Loans, with any exceptions noted thereon. Monthly Payments
due with respect to Replacement Mortgage Loans in the month of substitution
shall not be included as part of the Trust Fund and shall be retained by the
Seller. For the month of substitution, distributions to the Certificateholders
shall reflect the collections and recoveries in respect of such Deleted Mortgage
in the Due Period preceding the month of substitution and the Seller shall
thereafter be entitled to retain all amounts subsequently received in respect of
such Deleted Mortgage Loan. Upon such substitution, such Replacement Mortgage
Loan shall constitute part of the Trust Fund and shall be subject in all
respects to the terms of this Agreement and the Mortgage Loan Purchase and Sale
Agreement, including all representations and warranties thereof included in the
Mortgage Loan Purchase and Sale Agreement, in each case as of the date of
substitution.

         For any month in which the Seller substitutes one or more Replacement
Mortgage Loans for one or more Deleted Mortgage Loans, the related Servicer
shall determine the excess (each, a "Substitution Amount"), if any, by which the
aggregate Purchase Price of all such Deleted Mortgage Loans exceeds the
aggregate Stated Principal Balance of the Replacement Mortgage Loans replacing
such Deleted Mortgage Loans, together with one month's interest on such excess
amount at the applicable Net Mortgage Rate. On the date of such substitution,
the Seller, as applicable, shall deliver or cause to be delivered to the
Servicer for deposit in the Custodial Account an amount equal to the related
Substitution Amount, if any, and the related Custodian, on behalf of the
Trustee, upon receipt of the related Replacement Mortgage Loan or Loans and
certification by the Servicer of such deposit, shall release to the Seller the
related Trustee Mortgage File or Files and shall execute and deliver such
instruments of transfer or assignment,

                                       54



in each case without recourse, as the Seller shall deliver to it and as shall be
necessary to vest therein any Deleted Mortgage Loan released pursuant hereto.

         In addition, the Seller shall obtain at its own expense and deliver to
the Trustee and the Securities Administrator an Opinion of Counsel to the effect
that such substitution (either specifically or as a class of transactions) shall
not cause an Adverse REMIC Event. If such Opinion of Counsel can not be
delivered, then such substitution may only be effected at such time as the
required Opinion of Counsel can be given.

         (c)      Upon discovery by the Seller, the Depositor or the Trustee
that any Mortgage Loan does not constitute a "qualified mortgage" within the
meaning of Section 860G(a)(3) of the Code, the party discovering such fact shall
within two Business Days give written notice thereof to the other parties. In
connection therewith, the applicable party shall repurchase or, subject to the
limitations set forth in Section 2.04(b), substitute one or more Replacement
Mortgage Loans for the affected Mortgage Loan within 90 days of the earlier of
discovery or receipt of such notice with respect to such affected Mortgage Loan.
Any such repurchase or substitution shall be made in the same manner as set
forth in Section 2.04(a) above. The Trustee shall re-convey to the Seller the
Mortgage Loan to be released pursuant hereto in the same manner, and on the same
terms and conditions, as it would a Mortgage Loan repurchased for breach of a
representation or warranty.

         (d)      The Seller indemnifies and holds the Trust Fund, the Master
Servicer, the Securities Administrator, the Trustee, the Depositor and each
Certificateholder harmless against any and all taxes, claims, losses, penalties,
fines, forfeitures, reasonable legal fees and related costs, judgments, and any
other costs, fees and expenses that the Trust Fund, the Trustee, the Master
Servicer, the Securities Administrator, the Depositor and any Certificateholder
may sustain in connection with any actions of such party relating to a
repurchase of a Mortgage Loan other than in compliance with the terms of this
Section 2.04 and the Mortgage Loan Purchase and Sale Agreement, to the extent
that any such action causes an Adverse REMIC Event.

         Section 2.05 Delivery of Subsequent Mortgage Loans.

         (a)      On each Subsequent Transfer Date occurring during the
Pre-Funding Period, provided that each condition set forth in this Section 2.05
is satisfied, the Depositor shall convey to the Trust Fund and the Trustee shall
purchase on behalf of the Trust Fund for inclusion in Pool 1 or Pool 2, as
applicable, at the applicable Transfer Price set forth in the related Subsequent
Transfer Date Notice, all Subsequent Mortgage Loans which satisfy the criteria
set forth in this Section 2.05 then offered for sale by the Depositor; provided,
however, that the related aggregate purchase price paid for the Subsequent
Mortgage Loans shall not exceed the Original Pre-Funded Amount related to Pool 1
or Pool 2, as applicable; provided, further, that in the case of Pool 1, the
aggregate purchase price paid for Subsequent Mortgage Loans which (x) constitute
One-Month LIBOR Loans shall not exceed the initial deposit made to the 1M
Sub-account of the Pool 1 Pre-Funding Account and (y) constitute Six-Month LIBOR
Loans shall not exceed the initial deposit made to the 6M Sub-account of the
Pool 1 Pre-Funding Account, in each case as provided in Section 4.02.

         (b)      Subject to satisfaction of the conditions set forth in Section
2.05(c), in consideration of the Securities Administrator's delivery on the
related Subsequent Transfer Date to the

                                       55



Depositor or its designee, or upon the order of the Depositor, of the Transfer
Price for the related Subsequent Mortgage Loans from amounts on deposit in the
applicable Pre-Funding Account, the Depositor, on each Subsequent Transfer Date,
shall sell, transfer, assign, set over and otherwise convey to the Trustee on
behalf of the Trust Fund for inclusion in the related Mortgage Pool, without
recourse, but subject to the other terms and provisions of this Agreement, all
of the right, title and interest of the Depositor in and to each Subsequent
Mortgage Loan (including all interest and principal thereon received after the
related Subsequent Cut-off Date) identified in the related Subsequent Transfer
Date Notice delivered by the Depositor prior to such Subsequent Transfer Date
and all items in the related Trustee Mortgage File. In connection therewith, the
Depositor shall amend the Mortgage Loan Schedule to reflect the inclusion of the
Subsequent Mortgage Loan in the applicable Mortgage Pool as part of the assets
of the Trust Fund. The Depositor shall promptly deliver to the Trustee and the
Master Servicer a copy of the Mortgage Loan Schedule as so amended.

         (c)      The obligation of the Securities Administrator to release
funds from the Pool 1 Pre-Funding Account or the Pool 2 Pre-Funding Account, as
applicable, in respect of any Subsequent Mortgage Loans is subject to
satisfaction of each of the following conditions on or prior to the related
Subsequent Transfer Date:

                  (i)      at least ten (10) days prior to the Subsequent
         Transfer Date, the Depositor shall have delivered to the Trustee, the
         Securities Administrator and the Master Servicer a duly executed
         written Subsequent Transfer Date Notice which shall include a schedule
         of Subsequent Mortgage Loans specifying the related Mortgage Pool to
         which such Subsequent Mortgage Loans relate and the Transfer Price to
         be released from the related Pre-Funding Account or Sub Account;

                  (ii)     after giving effect to the acquisition of such
         Subsequent Mortgage Loans, the Mortgage Loans shall conform to the
         Subsequent Delivery Requirements applicable to such Mortgage Pool;

                  (iii)    no Subsequent Mortgage Loan shall have been selected
         in a manner adverse to the interest of Certificateholders;

                  (iv)     the weighted average Mortgage Rate for all the
         Mortgage Loans in the Trust Fund at the close of the Pre-Funding Period
         shall not be more than 50 basis points lower than the weighted average
         Mortgage Rate for the Initial Mortgage Loans transferred to the Trust
         Fund on the Closing Date;

                  (v)      the addition of the Subsequent Mortgage Loans shall
         not result in the reduction, qualification or withdrawal of the then
         current rating of the Certificates as evidenced by a letter from each
         Rating Agency rating the Certificate delivered by the Depositor to the
         Trustee and the Securities Administrator dated the applicable
         Subsequent Transfer Date;

                  (vi)     each Subsequent Mortgage Loan shall be underwritten
         in accordance with the applicable underwriting guidelines for the
         related originator;

                                       56



                  (vii)    the Depositor shall have delivered to the Trustee and
         the Securities Administrator a letter from an independent accountant
         stating whether or not the characteristics of the Subsequent Mortgage
         Loans conform to the characteristics of the Mortgage Loans required in
         this Section 2.05(b);

                  (viii)   as of each Transfer Date, neither the Depositor nor
         the Seller shall be insolvent, nor will either of them be made
         insolvent by such transfer;

                  (ix)     the Pre-Funding Period shall not have ended;

                  (x)      the Depositor shall have delivered to the Master
         Servicer a copy of the related Servicing Agreement and executed
         Acknowledgement (if not previously delivered to the Master Servicer on
         or before the Closing Date) in respect of each such Subsequent Mortgage
         Loan, and such loan level data, in electronic or other format
         acceptable to the Master Servicer and the Depositor, as shall be
         necessary for the proper master servicing of such Subsequent Mortgage
         Loans by the Master Servicer;

                  (xi)     the Depositor shall have delivered to the Trustee and
         the Securities Administrator an Officer's Certificate confirming the
         satisfaction of each condition precedent specified in the Section 2.05
         and Opinions of Counsel with respect to corporate, bankruptcy and tax
         matters relating to the transfer of Subsequent Mortgage Loans in the
         form substantially similar to those delivered on the Closing Date
         pursuant to the Underwriting Agreement; and

                  (xii)    the Depositor shall have delivered to the Trustee,
         the Master Servicer, the Securities Administrator and each Rating
         Agency such additional information reasonably requested by any of them
         with respect to the Subsequent Mortgage Loans to be sold to the Trust
         on the Subsequent Transfer Date.

         The Depositor shall cause the applicable Servicer to deposit in the
Custodial Account within two Business Days following each Subsequent Transfer
Date all collections in respect to the related Subsequent Mortgage Loans
received after the related Subsequent Cut-off Date.

         Section 2.06 Grant Clause.

         (a)      It is intended that the conveyance of the Depositor's right,
title and interest in and to property constituting the Trust Fund pursuant to
this Agreement shall constitute, and shall be construed as, a sale of such
property and not a grant of a security interest to secure a loan. However, if
such conveyance is deemed to be in respect of a loan, it is intended that: (1)
the rights and obligations of the parties shall be established pursuant to the
terms of this Agreement; (2) the Depositor hereby grants to the Trustee for the
benefit of the Holders of the Certificates a first priority security interest in
all of the Depositor's right, title and interest in, to and under, whether now
owned or hereafter acquired, the Trust Fund and all proceeds of any and all
property constituting the Trust Fund to secure payment of the Certificates; and
(3) this Agreement shall constitute a security agreement under applicable law.
If such conveyance is deemed to be in respect of a loan and the trust created by
this Agreement terminates prior to the satisfaction of the claims of any Person
holding any Certificate, the security interest created

                                       57



hereby shall continue in full force and effect and the Trustee shall be deemed
to be the collateral agent for the benefit of such Person, and all proceeds
shall be distributed as herein provided.

         (b)      The Depositor shall, to the extent consistent with this
Agreement, take such reasonable actions as may be necessary to ensure that, if
this Agreement were deemed to create a security interest in the Mortgage Loans
and the other property described above, such security interest would be deemed
to be a perfected security interest of first priority under applicable law and
will be maintained as such throughout the term of this Agreement. The Depositor
will, at its own expense, make all initial filings on or about the Closing Date
and shall forward a copy of such filing or filings to the Trustee. Without
limiting the generality of the foregoing, the Depositor shall prepare and
forward for filing, or shall cause to be forwarded for filing, at the expense of
the Depositor, all filings necessary to maintain the effectiveness of any
original filings necessary under the relevant UCC to perfect the Trustee's
security interest in or lien on the Mortgage Loans, including without limitation
(x) continuation statements, and (y) such other statements as may be occasioned
by (1) any change of name of the Seller, the Depositor or the Trustee, (2) any
change of location of the place of business or the chief executive office of the
Seller or the Depositor, (3) any transfer of any interest of the Seller or the
Depositor in any Mortgage Loan or (4) any change under the relevant UCC or other
applicable laws. Neither of the Seller nor the Depositor shall organize under
the law of any jurisdiction other than the State under which each is organized
as of the Closing Date (whether changing its jurisdiction of organization or
organizing under an additional jurisdiction) without giving 30 days prior
written notice of such action to its immediate and intermediate transferee,
including the Trustee. Before effecting such change, the Seller or the Depositor
proposing to change its jurisdiction of organization shall prepare and file in
the appropriate filing office any financing statements or other statements
necessary to continue the perfection of the interests of its immediate and
mediate transferees, including the Trustee, in the Mortgage Loans. In connection
with the transactions contemplated by this Agreement, each of the Seller and the
Depositor authorizes its immediate or mediate transferee to file in any filing
office any initial financing statements, any amendments to financing statements,
any continuation statements, or any other statements or filings described in
this paragraph (b).

                                  ARTICLE III

                                THE CERTIFICATES

         Section 3.01 The Certificates.

         (a)      The Certificates shall be issuable in registered form only and
shall be securities governed by Article 8 of the New York Uniform Commercial
Code. The Book-Entry Certificates will be evidenced by one or more certificates,
beneficial ownership of which will be held in the dollar denominations in
Certificate Principal Amount, or Notional Amount, as applicable, or in the
Percentage Interests, specified herein. Each Class of Book-Entry Certificates
will be issued in the minimum denominations in Certificate Principal Amount (or
Notional Amount) specified in the Preliminary Statement hereto and in integral
multiples of $1 in excess thereof. Each Class of Non-Book-Entry Certificates
other than the Residual Certificates shall be issued in definitive, fully
registered form in the minimum denominations in Certificate Principal Amount
specified in the Preliminary Statement hereto and in integral multiples of $1 in
excess thereof. The Residual Certificates shall be issued as single Certificates

                                       58



and maintained in definitive, fully registered form in a denomination equal to
100% of the Percentage Interest of each such Class. The Class Class X-2 and
Class X-B Certificates shall be issued as single Certificates in a denomination
equal to 100% of the Percentage Interest of each such Class.

         (b)      The Certificates shall be executed by manual or facsimile
signature on behalf of the Trustee by an authorized officer. Each Certificate
shall, on original issue, be authenticated by the Authenticating Agent upon the
order of the Depositor upon receipt by the Trustee of the Trustee Mortgage Files
described in Section 2.01. No Certificate shall be entitled to any benefit under
this Agreement, or be valid for any purpose, unless there appears on such
Certificate a certificate of authentication substantially in the form provided
for herein, executed by an authorized officer of the Authenticating Agent, by
manual signature, and such certification upon any Certificate shall be
conclusive evidence, and the only evidence, that such Certificate has been duly
authenticated and delivered hereunder. All Certificates shall be dated the date
of their authentication. At any time and from time to time after the execution
and delivery of this Agreement, the Depositor may deliver Certificates executed
by the Trustee to the Authenticating Agent for authentication and the
Authenticating Agent shall authenticate and deliver such Certificates as in this
Agreement provided and not otherwise.

         (c)      The Class B-4, Class B-5, Class B-6, Class A-R and Class LT-R
Certificates offered and sold in reliance on the exemption from registration
under Rule 144A under the Act shall be issued initially in definitive, fully
registered form without interest coupons with the applicable legends set forth
in Exhibit A added to the forms of such Certificates (each, a "Restricted Global
Security").

         Section 3.02 Registration.

         The Securities Administrator is hereby appointed, and the Securities
Administrator hereby accepts its appointment as, initial Certificate Registrar
in respect of the Certificates and shall maintain books for the registration and
for the transfer of Certificates (the "Certificate Register"). The Trustee may
appoint a bank or trust company to act as successor Certificate Registrar. A
registration book shall be maintained for the Certificates collectively. The
Certificate Registrar may resign or be discharged or removed and a new successor
may be appointed in accordance with the procedures and requirements set forth in
Sections 6.06 and 6.07 hereof with respect to the resignation, discharge or
removal of the Securities Administrator and the appointment of a successor
Securities Administrator. The Certificate Registrar may appoint, by a written
instrument delivered to the Holders and the Master Servicer, any bank or trust
company to act as co-registrar under such conditions as the Certificate
Registrar may prescribe; provided, however, that the Certificate Registrar shall
not be relieved of any of its duties or responsibilities hereunder by reason of
such appointment.

         Section 3.03 Transfer and Exchange of Certificates.

         (a)      A Certificate (other than Book-Entry Certificates which shall
be subject to Section 3.09 hereof) may be transferred by the Holder thereof only
upon presentation and surrender of such Certificate at the office of the
Certificate Registrar duly endorsed or accompanied by an assignment duly
executed by such Holder or his duly authorized attorney in such form as shall be
satisfactory to the Certificate Registrar. Upon the transfer of any

                                       59



Certificate in accordance with the preceding sentence, the Trustee shall
execute, and the Authenticating Agent shall authenticate and deliver to the
transferee, one or more new Certificates of the same Class and evidencing, in
the aggregate, the same aggregate Certificate Principal Amount (or Notional
Amount) as the Certificate being transferred. No service charge shall be made to
a Certificateholder for any registration of transfer of Certificates, but the
Certificate Registrar may require payment of a sum sufficient to cover any tax
or governmental charge that may be imposed in connection with any registration
of transfer of Certificates.

         (b)      A Certificate may be exchanged by the Holder thereof for any
number of new Certificates of the same Class, in authorized denominations,
representing in the aggregate the same Certificate Principal Amount (or Notional
Amount) as the Certificate surrendered, upon surrender of the Certificate to be
exchanged at the office of the Certificate Registrar duly endorsed or
accompanied by a written instrument of transfer duly executed by such Holder or
his duly authorized attorney in such form as is satisfactory to the Certificate
Registrar. Certificates delivered upon any such exchange will evidence the same
obligations, and will be entitled to the same rights and privileges, as the
Certificates surrendered. No service charge shall be made to a Certificateholder
for any exchange of Certificates, but the Certificate Registrar may require
payment of a sum sufficient to cover any tax or governmental charge that may be
imposed in connection with any exchange of Certificates. Whenever any
Certificates are so surrendered for exchange, the Trustee shall execute, and the
Authenticating Agent shall authenticate, date and deliver the Certificates which
the Certificateholder making the exchange is entitled to receive.

         (c)      By acceptance of a Restricted Certificate, whether upon
original issuance or subsequent transfer, each Holder of such a Certificate
acknowledges the restrictions on the transfer of such Certificate set forth
thereon and agrees that it will transfer such a Certificate only as provided
herein.

         The following restrictions shall apply with respect to the transfer and
registration of transfer of a Restricted Certificate to a transferee that takes
delivery in the form of a Definitive Certificate:

                  (i)      The Certificate Registrar shall register the transfer
         of a Restricted Certificate if the requested transfer is (x) to the
         Depositor or an affiliate (as defined in Rule 405 under the 1933 Act)
         of the Depositor or (y) being made to a "qualified institutional buyer"
         (a "QIB") as defined in Rule 144A under the Securities Act of 1933, as
         amended (the "Act") by a transferor that has provided the Certificate
         Registrar with a certificate in the form of Exhibit H hereto; and

                  (ii)     The Certificate Registrar shall register the transfer
         of a Restricted Certificate if the requested transfer is being made to
         an "accredited investor" under Rule 501(a)(1), (2), (3) or (7) under
         the Act, or to any Person all of the equity owners in which are such
         accredited investors, by a transferor who furnishes to the Certificate
         Registrar a letter of the transferee substantially in the form of
         Exhibit I hereto.

         (d)      No transfer of an ERISA-Restricted Certificate in the form of
a Definitive Certificate shall be made to any Person or shall be effective
unless the Certificate Registrar, on behalf of the Trustee, has received (A) a
certificate substantially in the form of Exhibit J hereto (or Exhibit B, in the
case of a Residual Certificate) from such transferee or (B) an Opinion of

                                       60



Counsel satisfactory to the Certificate Registrar to the effect that the
purchase and holding of such a Certificate will not constitute or result in
prohibited transactions under Title I of ERISA or Section 4975 of the Code and
will not subject the Certificate Registrar, the Trustee, the Master Servicer,
the Depositor or the Securities Administrator to any obligation in addition to
those undertaken in the Agreement; provided, however, that the Certificate
Registrar will not require such certificate or opinion in the event that, as a
result of a change of law or otherwise, counsel satisfactory to the Certificate
Registrar has rendered an opinion to the effect that the purchase and holding of
an ERISA-Restricted Certificate by a Plan or a Person that is purchasing or
holding such a Certificate with the assets of a Plan will not constitute or
result in a prohibited transaction under Title I of ERISA or Section 4975 of the
Code. Each Transferee of an ERISA-Restricted Certificate that is a Book-Entry
Certificate shall be deemed to have made the representations set forth in
Exhibit J. The preparation and delivery of the certificate and opinions referred
to above shall not be an expense of the Trust Fund, the Certificate Registrar,
the Trustee, the Master Servicer, the Depositor or the Securities Administrator.

         Notwithstanding the foregoing, no opinion or certificate shall be
required for the initial issuance of the ERISA-Restricted Certificates. The
Certificate Registrar shall have no obligation to monitor transfers of
Book-Entry Certificates that are ERISA-Restricted Certificates and shall have no
liability for transfers of such Certificates in violation of the transfer
restrictions. The Certificate Registrar shall be under no liability to any
Person for any registration of transfer of any ERISA-Restricted Certificate that
is in fact not permitted by this Section 3.03(d) and none of the Securities
Administrator, the Trustee or the Paying Agent shall have any liability for
making any payments due on such Certificate to the Holder thereof or taking any
other action with respect to such Holder under the provisions of this Agreement
so long as the transfer was registered by the Certificate Registrar in
accordance with the foregoing requirements. The Securities Administrator, on
behalf of the Trustee, shall be entitled, but not obligated, to recover from any
Holder of any ERISA-Restricted Certificate that was in fact a Plan or a Person
acting on behalf of a Plan any payments made on such ERISA-Restricted
Certificate at and after either such time. Any such payments so recovered by the
Securities Administrator, on behalf of the Trustee, shall be paid and delivered
by the Securities Administrator, on behalf of the Trustee, to the last preceding
Holder of such Certificate that is not such a Plan or Person acting on behalf of
a Plan.

         (e)      As a condition of the registration of transfer or exchange of
any Certificate, the Certificate Registrar may require the certified taxpayer
identification number of the owner of the Certificate and the payment of a sum
sufficient to cover any tax or other governmental charge imposed in connection
therewith; provided, however, that the Certificate Registrar shall have no
obligation to require such payment or to determine whether or not any such tax
or charge may be applicable. No service charge shall be made to the
Certificateholder for any registration, transfer or exchange of a Certificate.

         (f)      Notwithstanding anything to the contrary contained herein, no
Residual Certificate may be owned, pledged or transferred, directly or
indirectly, by or to (i) a Disqualified Organization or (ii) an individual,
corporation or partnership or other person unless such person is (A) not a
Non-U.S. Person or (B) is a Non-U.S. Person that holds a Residual Certificate in
connection with the conduct of a trade or business within the United States and
has furnished the transferor and the Certificate Registrar with an effective
Internal Revenue Service

                                       61



Form W-8ECI or successor form at the time and in the manner required by the Code
(any such person who is not covered by clause (A) or (B) above is referred to
herein as a "Non-permitted Foreign Holder").

         Prior to and as a condition of the registration of any transfer, sale
or other disposition of a Residual Certificate, the proposed transferee shall
deliver to the Trustee and the Certificate Registrar an affidavit in
substantially the form attached hereto as Exhibit B representing and warranting,
among other things, that such transferee is neither a Disqualified Organization,
an agent or nominee acting on behalf of a Disqualified Organization, nor a
Non-permitted Foreign Holder (any such transferee, a "Permitted Transferee"),
and the proposed transferor shall deliver to the Trustee and the Certificate
Registrar an affidavit in substantially the form attached hereto as Exhibit C.
In addition, the Trustee or the Certificate Registrar may (but shall have no
obligation to) require, prior to and as a condition of any such transfer, the
delivery by the proposed transferee of an Opinion of Counsel, addressed to the
Trustee and the Certificate Registrar, that such proposed transferee or, if the
proposed transferee is an agent or nominee, the proposed beneficial owner, is
not a Disqualified Organization, agent or nominee thereof, or a Non-permitted
Foreign Holder. Notwithstanding the registration in the Certificate Register of
any transfer, sale, or other disposition of a Residual Certificate to a
Disqualified Organization, an agent or nominee thereof, or Non-permitted Foreign
Holder, such registration shall be deemed to be of no legal force or effect
whatsoever and such Disqualified Organization, agent or nominee thereof, or
Non-permitted Foreign Holder shall not be deemed to be a Certificateholder for
any purpose hereunder, including, but not limited to, the receipt of
distributions on such Residual Certificate. The Depositor, the Certificate
Registrar and the Trustee shall be under no liability to any Person for any
registration or transfer of a Residual Certificate to a Disqualified
Organization, agent or nominee thereof or Non-permitted Foreign Holder or for
the Paying Agent making any payments due on such Residual Certificate to the
Holder thereof or for taking any other action with respect to such Holder under
the provisions of the Agreement, so long as the transfer was effected in
accordance with this Section 3.03(f), unless the Certificate Registrar shall
have actual knowledge at the time of such transfer or the time of such payment
or other action that the transferee is a Disqualified Organization, or an agent
or nominee thereof, or Non-permitted Foreign Holder. The Certificate Registrar
shall be entitled to recover from any Holder of a Residual Certificate that was
a Disqualified Organization, agent or nominee thereof, or Non-permitted Foreign
Holder at the time it became a Holder or any subsequent time it became a
Disqualified Organization, agent or nominee thereof, or Non-permitted Foreign
Holder, all payments made on such Residual Certificate at and after either such
times (and all costs and expenses, including but not limited to attorneys' fees,
incurred in connection therewith). Any payment (not including any such costs and
expenses) so recovered by the Certificate Registrar shall be paid and delivered
to the last preceding Holder of such Residual Certificate.

         If any purported transferee shall become a registered Holder of a
Residual Certificate in violation of the provisions of this Section 3.03(f),
then upon receipt of written notice to the Trustee that the registration of
transfer of such Residual Certificate was not in fact permitted by this Section
3.03(f), the last preceding Permitted Transferee shall be restored to all rights
as Holder thereof retroactive to the date of such registration of transfer of
such Residual Certificate. The Depositor, the Certificate Registrar and the
Trustee shall be under no liability to any Person for any registration of
transfer of a Residual Certificate that is in fact not permitted by this Section
3.03(f), or for the Paying Agent making any payment due on such Certificate to
the

                                       62



registered Holder thereof or for taking any other action with respect to such
Holder under the provisions of this Agreement so long as the transfer was
registered upon receipt of the affidavit described in the preceding paragraph of
this Section 3.03(f).

         (g)      Each Holder or Certificate Owner of a Restricted Certificate,
ERISA-Restricted Certificate or Residual Certificate, or an interest therein, by
such Holder's or Owner's acceptance thereof, shall be deemed for all purposes to
have consented to the provisions of this section.

         Section 3.04 Cancellation of Certificates.

         Any Certificate surrendered for registration of transfer or exchange
shall be cancelled and retained in accordance with normal retention policies
with respect to cancelled certificates maintained by the Trustee or the
Certificate Registrar.

         Section 3.05 Replacement of Certificates.

         If (i) any Certificate is mutilated and is surrendered to the Trustee
or the Certificate Registrar or (ii) the Trustee or the Certificate Registrar
receives evidence to its satisfaction of the destruction, loss or theft of any
Certificate, and there is delivered to the Trustee and the Certificate Registrar
such security or indemnity as may be required by them to save each of them
harmless, then, in the absence of notice to the Depositor, the Trustee or the
Certificate Registrar that such destroyed, lost or stolen Certificate has been
acquired by a protected purchaser, the Trustee shall execute and the
Authenticating Agent shall authenticate and deliver, in exchange for or in lieu
of any such mutilated, destroyed, lost or stolen Certificate, a new Certificate
of like tenor and Certificate Principal Amount. Upon the issuance of any new
Certificate under this Section 3.05, the Trustee, the Depositor or the
Certificate Registrar may require the payment of a sum sufficient to cover any
tax or other governmental charge that may be imposed in relation thereto and any
other expenses (including the fees and expenses of the Trustee, the Depositor or
the Certificate Registrar) connected therewith. Any replacement Certificate
issued pursuant to this Section 3.05 shall constitute complete and indefeasible
evidence of ownership in the applicable Trust Fund, as if originally issued,
whether or not the lost, stolen or destroyed Certificate shall be found at any
time.

         If after the delivery of such new Certificate, a protected purchaser of
the original Certificate in lieu of which such new Certificate was issued
presents for payment such original Certificate, the Depositor, the Certificate
Registrar and the Trustee or any agent shall be entitled to recover such new
Certificate from the Person to whom it was delivered or any Person taking
therefrom, except a protected purchaser, and shall be entitled to recover upon
the security or indemnity provided therefor to the extent of any loss, damage,
cost or expenses incurred by the Depositor, the Certificate Registrar, the
Trustee or any agent in connection therewith.

         Section 3.06 Persons Deemed Owners.

         Subject to the provisions of Section 3.09 with respect to Book-Entry
Certificates, the Depositor, the Master Servicer, the Trustee, the Certificate
Registrar, the Paying Agent and any agent of any of them shall treat the Person
in whose name any Certificate is registered upon the books of the Certificate
Registrar as the owner of such Certificate for the purpose of receiving

                                       63



distributions pursuant to Sections 5.01 and 5.02 and for all other purposes
whatsoever, and neither the Depositor, the Master Servicer, the Trustee, the
Certificate Registrar, the Paying Agent nor any agent of any of them shall be
affected by notice to the contrary.

         Section 3.07 Temporary Certificates.

         (a)      Pending the preparation of definitive Certificates, upon the
order of the Depositor, the Trustee shall execute and the Authenticating Agent
shall authenticate and deliver temporary Certificates that are printed,
lithographed, typewritten, mimeographed or otherwise produced, in any authorized
denomination, substantially of the tenor of the definitive Certificates in lieu
of which they are issued and with such variations as the authorized officers
executing such Certificates may determine, as evidenced by their execution of
such Certificates.

         (b)      If temporary Certificates are issued, the Depositor will cause
definitive Certificates to be prepared without unreasonable delay. After the
preparation of definitive Certificates, the temporary Certificates shall be
exchangeable for definitive Certificates upon surrender of the temporary
Certificates at the office or agency of the Certificate Registrar without charge
to the Holder. Upon surrender for cancellation of any one or more temporary
Certificates, the Trustee shall execute and the Authenticating Agent shall
authenticate and deliver in exchange therefor a like aggregate Certificate
Principal Amount of definitive Certificates of the same Class in the authorized
denominations. Until so exchanged, the temporary Certificates shall in all
respects be entitled to the same benefits under this Agreement as definitive
Certificates of the same Class.

         Section 3.08 Appointment of Paying Agent.

         The Trustee may appoint a Paying Agent (which may be the Trustee) for
the purpose of making distributions to the Certificateholders hereunder. The
Trustee hereby appoints the Securities Administrator as the initial Paying
Agent. The Trustee shall cause any Paying Agent, other than the Securities
Administrator, to execute and deliver to the Trustee an instrument in which such
Paying Agent shall agree with the Trustee that such Paying Agent will hold all
sums held by it for the payment to the Certificateholders in an Eligible Account
(which shall be the Distribution Account) in trust for the benefit of the
Certificateholders entitled thereto until such sums shall be paid to the
Certificateholders. All funds remitted by the Trustee to any such Paying Agent
for the purpose of making distributions shall be paid to the Certificateholders
on each Distribution Date and any amounts not so paid shall be returned on such
Distribution Date to the Trustee. If the Paying Agent is not the Trustee, the
Trustee shall cause to be remitted to the Paying Agent on or before the Business
Day prior to each Distribution Date, by wire transfer in immediately available
funds, the funds to be distributed on such Distribution Date. Any Paying Agent
shall be either a bank or trust company or otherwise authorized under law to
exercise corporate trust powers.

         Section 3.09 Book-Entry Certificates.

         (a)      Each Class of Book-Entry Certificates, upon original issuance,
shall be issued in the form of one or more typewritten Certificates representing
the Book-Entry Certificates. The Book-Entry Certificates shall initially be
registered on the Certificate Register in the name of the nominee of the
Clearing Agency, and no Certificate Owner will receive a definitive certificate

                                       64



representing such Certificate Owner's interest in the Book-Entry Certificates,
except as provided in Section 3.09(c). Unless Definitive Certificates have been
issued to Certificate Owners of Book-Entry Certificates pursuant to Section
3.09(c):

                  (i)      the provisions of this Section 3.09 shall be in full
         force and effect;

                  (ii)     the Certificate Registrar, the Paying Agent and the
         Trustee shall deal with the Clearing Agency for all purposes (including
         the making of distributions on the Book-Entry Certificates) as the
         authorized representatives of the Certificate Owners and the Clearing
         Agency and shall be responsible for crediting the amount of such
         distributions to the accounts of such Persons entitled thereto, in
         accordance with the Clearing Agency's normal procedures;

                  (iii)    to the extent that the provisions of this Section
         3.09 conflict with any other provisions of this Agreement, the
         provisions of this Section 3.09 shall control; and

                  (iv)     the rights of Certificate Owners shall be exercised
         only through the Clearing Agency and the Clearing Agency Participants
         and shall be limited to those established by law and agreements between
         such Certificate Owners and the Clearing Agency and/or the Clearing
         Agency Participants. Unless and until Definitive Certificates are
         issued pursuant to Section 3.09(c), the initial Clearing Agency will
         make book-entry transfers among the Clearing Agency Participants and
         receive and transmit distributions of principal of and interest on the
         Book-Entry Certificates to such Clearing Agency Participants.

         (b)      Whenever notice or other communication to the
Certificateholders is required under this Agreement, unless and until Definitive
Certificates shall have been issued to Certificate Owners pursuant to Section
3.09(c), the Securities Administrator shall give all such notices and
communications specified herein to be given to Holders of the Book-Entry
Certificates to the Clearing Agency.

         (c)      If (i) (A) the Clearing Agency or the Depositor advises the
Paying Agent in writing that the Clearing Agency is no longer willing or able to
discharge properly its responsibilities with respect to the Book-Entry
Certificates, and (B) the Depositor is unable to locate a qualified successor
satisfactory to the Depositor and the Paying Agent, (ii) the Depositor, at its
option, advises the Paying Agent in writing that it elects to terminate the
book-entry system through the Clearing Agency or (iii) after the occurrence of
an Event of Default, Certificate Owners representing beneficial interests
aggregating not less than 50% of the Class Principal Amount of a Class of
Book-Entry Certificates advise the Paying Agent and the Clearing Agency through
the Clearing Agency Participants in writing that the continuation of a
book-entry system through the Clearing Agency is no longer in the best interests
of the Certificate Owners of a Class of Book-Entry Certificates, the Certificate
Registrar shall notify the Clearing Agency to effect notification to all
Certificate Owners, through the Clearing Agency, of the occurrence of any such
event and of the availability of Definitive Certificates to Certificate Owners
requesting the same. Upon surrender to the Certificate Registrar of the
Book-Entry Certificates by the Clearing Agency, accompanied by registration
instructions from the Clearing Agency for registration, the Certificate
Registrar shall issue the Definitive Certificates. Neither the Depositor, the
Certificate Registrar nor the Trustee shall be liable for

                                       65



any delay in delivery of such instructions and may conclusively rely on, and
shall be protected in relying on, such instructions. Upon the issuance of
Definitive Certificates all references herein to obligations imposed upon or to
be performed by the Clearing Agency shall be deemed to be imposed upon and
performed by the Certificate Registrar, to the extent applicable, with respect
to such Definitive Certificates and the Certificate Registrar shall recognize
the holders of the Definitive Certificates as Certificateholders hereunder.
Notwithstanding the foregoing, the Certificate Registrar, upon the instruction
of the Depositor, shall have the right to issue Definitive Certificates on the
Closing Date in connection with credit enhancement programs.

                                   ARTICLE IV

                        ADMINISTRATION OF THE TRUST FUND

         Section 4.01 Custodial Accounts; Distribution Account.

         (a)      On or prior to the Closing Date, the Master Servicer shall
have caused the Servicers to establish and maintain one or more Custodial
Accounts, as provided in the related Servicing Agreements, into which all
Scheduled Payments and unscheduled payments with respect to the Mortgage Loans,
net of any deductions or reimbursements permitted under the related Servicing
Agreement, shall be deposited. On each Distribution Account Deposit Date, the
Servicers shall remit to the Securities Administrator for deposit into the
Distribution Account, all amounts so required to be deposited into such account
in accordance with the terms of the related Servicing Agreement.

         (b)      The Securities Administrator, as Paying Agent for the Trustee,
shall establish and maintain an Eligible Account entitled "Distribution Account
of HSBC Bank, USA, as Trustee for the benefit of Sequoia Mortgage Trust 2003-7
Holders of Mortgage Pass-Through Certificates." The Securities Administrator
shall, promptly upon receipt from the Servicers on each Distribution Account
Deposit Date, deposit into the Distribution Account and retain on deposit until
the related Distribution Date the following amounts:

                  (i)      the aggregate of collections with respect to the
         Mortgage Loans remitted by the Servicers from the related Custodial
         Accounts in accordance with the Servicing Agreements;

                  (ii)     any amounts required to be deposited by the Master
         Servicer with respect to the Mortgage Loans for the related Due Period
         pursuant to this Agreement, including the amount of any Advances or
         Compensation Interest Payments with respect to the Mortgage Loans not
         paid by the Servicers; and

                  (iii)    any other amounts so required to be deposited in the
         Distribution Account in the related Due Period pursuant to this
         Agreement.

         (c)      In the event the Master Servicer or a Servicer has remitted in
error to the Distribution Account any amount not required to be remitted in
accordance with the definition of Available Distribution Amount, it may at any
time direct the Securities Administrator to withdraw such amount from the
Distribution Account for repayment to the Master Servicer or

                                       66



Servicer, as applicable, by delivery of an Officer's Certificate to the
Securities Administrator and the Trustee which describes the amount deposited in
error.

         (d)      On each Distribution Date and Redemption Date, the Securities
Administrator, as Paying Agent, shall distribute the Available Distribution
Amount to the Certificateholders and any other parties entitled thereto in the
amounts and priorities set forth in Section 5.02. The Securities Administrator
may from time to time withdraw from the Distribution Account and pay the Master
Servicer, the Trustee, the Securities Administrator or any Servicer any amounts
permitted to be paid or reimbursed to such Person from funds in the Distribution
Account pursuant to the clauses (A) through (D) of the definition of Available
Distribution Amount.

         (e)      Funds in the Distribution Account may be invested in Permitted
Investments selected by and at the written direction of the Securities
Administrator, which shall mature not later than one Business Day prior to the
Distribution Date (except that if such Permitted Investment is an obligation of
the Securities Administrator, then such Permitted Investment shall mature not
later than such applicable Distribution Date) and any such Permitted Investment
shall not be sold or disposed of prior to its maturity. All such Permitted
Investments shall be made in the name of the Trustee (in its capacity as such)
or its nominee. All income and gain realized from any Permitted Investment shall
be for the benefit of the Securities Administrator, as additional compensation
for its duties hereunder, and shall be subject to its withdrawal or order from
time to time, and shall not be part of the Trust Fund. The amount of any losses
incurred in respect of any such investments shall be deposited in such
Distribution Account by the Securities Administrator out of its own funds,
without any right of reimbursement therefor, immediately as realized.

         Section 4.02 The Pre-Funding Accounts

         (a) The Securities Administrator, as Paying Agent for the Trustee,
shall establish and maintain two Eligible Accounts, each to be held in trust for
the benefit of Certificateholders, the first such Eligible Account entitled
"Pool 1 Pre-Funding Account of HSBC Bank, USA, as Trustee, for the benefit of
Sequoia Mortgage Trust 2003-7 Holders of Mortgage Pass-Through Certificates" and
the second entitled "Pool 2 Pre-Funding Account of HSBC Bank, USA, as Trustee,
for the benefit of Sequoia Mortgage Trust 2003-7 Holders of Mortgage
Pass-Through Certificates." The Pooling 1 Pre-Funding Account shall be comprised
of two Sub Accounts, the first entitled the "1M Sub-account" and the second
entitled the "6M Sub-account."

         (b) On the Closing Date, the Depositor will cause to be deposited to
the Pool 1 Pre-Funding Account the Original Pre-Funded Amount relating to Pool 1
and to the Pool 2 Pre-Funding Account the Original Pre-Funded Amount relating to
Pool 2. The Original Pre-Funded Amount relating to Pool 1 shall be further
allocated between the 1M Sub-account and the 6M Sub-account as follows:
$11,699,526.19 to the 1M Sub-account; and $27,087,938.69 to the 6M Sub-account.

         (c) Amounts on deposit in the 1M Sub-account (exclusive of investment
earnings thereon) shall solely be applied to acquire Subsequent Mortgage Loans
for inclusion in Pool 1 which constitute One-Month LIBOR Loans. Amounts on
deposit in the 6M Sub-account (exclusive of investment earnings thereon) shall
solely be applied to acquire Subsequent Mortgage Loans for inclusion in Pool 1
which constitute Six-Month LIBOR Loans. Amounts on

                                       67



deposit in the Pool 2 Pre-Funding Account (exclusive of investment earnings
thereon) shall solely be applied to acquire Subsequent Mortgage Loans for
inclusion in Pool 2. Funds on deposit in either Pre-Funding Account (or Sub
Account) may not be commingled with funds on deposit in the other Pre-Funding
Account (or Sub Account).

         (d) On any Subsequent Transfer Date, the Depositor shall instruct the
Securities Administrator, in writing, to withdraw funds from the applicable
Pre-Funding Account (specifying the applicable Sub Account in the case of Pool
1) in an amount equal to the Transfer Price for the Subsequent Mortgage Loans to
be acquired on such Subsequent Transfer Date, and to pay such amount to the
order of the Depositor. In no event shall the Securities Administrator withdraw
from the related Pre-Funding Account an amount in excess of the Original
Pre-Funded Amount (or portion thereof) deposited to such Account (or Sub Account
thereof) on the Closing Date.

         (e) During the Pre-Funding Period, amounts on deposit in the
Pre-Funding Accounts may be invested in Permitted Investments by the Securities
Administrator at the direction of the Depositor, or in absence of direction from
the Depositor, in money market funds described in paragraph (ix) of the
definition of Permitted Investments in Article I. All such Permitted Investments
shall be made in the name of the Trustee (in its capacity as such) or its
nominee. Any investment earnings on such Permitted Investments held in the
Pre-Funding Accounts shall be immediately transferred to the Distribution
Account and constitute part of the Available Distribution Amount for
distribution to the related Certificateholders on the next succeeding
Distribution Date.

         (f) On the Distribution Date immediately following the close of the
Pre-Funding Period, the Securities Administrator, as Paying Agent, shall
transfer any remaining Pool 1 Pre-Funded Amount or Pool 2 Pre-Funded Amount on
deposit in the related Pre-Funding Account (or Sub Account thereof) to the
Distribution Account for distribution to the Related Certificate Group as
principal on such Distribution Date in accordance with the priorities set forth
in Section 5.02 and terminate such Account.

         (g) The Pre-Funding Accounts shall not be an asset of any REMIC created
under this Agreement.

         Section 4.03 The Capitalized Interest Account.

         (a) The Securities Administrator, as Paying Agent, for the Trustee,
shall establish and maintain an Eligible Account, to be held in trust for the
benefit of Certificateholders, entitled "Capitalized Interest Account of HSBC
Bank, USA, as Trustee, for the benefit of Sequoia Mortgage Trust 2003-7 Holders
of Mortgage Pass-Through Certificates." On the Closing Date, the Depositor shall
cause to be deposited in the Capitalized Interest Account the Original
Capitalized Interest Amount. On each Distribution Date, funds in the Capitalized
Interest Account equal to the Capitalized Interest Requirement for such
Distribution Date shall be withdrawn by the Securities Administrator from the
Capitalized Interest Account and deposited into the Distribution Account as
required by Section 5.02(a).

         (b) During the Pre-Funding Period, amounts on deposit in the
Capitalized Interest Account may, at the direction of the Depositor, be invested
in Permitted Investments, and in the

                                       68



absence of such instructions shall be invested in money market funds as
described in paragraph (ix) of the definition of Permitted Investments in
Article I. All investment earnings on such Permitted Investments in the
Capitalized Interest Account shall be for the benefit of the Depositor. At the
close of the Pre-Funding period, all amounts, if any, remaining in the
Capitalized Interest Account shall be released to the Depositor and the
Securities Administrator shall terminate such Account.

         (c) The Capitalized Interest Account shall not be the asset of any
REMIC created under this Agreement.

         Section 4.04 Reports to Trustee and Certificateholders.

         On each Distribution Date, the Securities Administrator shall have
prepared and shall make available to the Trustee and each Certificateholder a
written report setting forth the following information (on the basis of Mortgage
Loan level information obtained from the Master Servicer and the Servicers):

giving effect to the distribution of principal on that Distribution Date;

Mortgage Pool at the end of the related Prepayment Period;

         (g)      the Stated Principal Balance of the Mortgage Loans in each

         Upon the reasonable advance written request of any Certificateholder
that is a savings and loan, bank or insurance company, which request, if
received by the Trustee or any agent thereof, shall be promptly forwarded to the
Securities Administrator, the Securities Administrator shall provide, or cause

                    DISTRIBUTIONS TO HOLDERS OF CERTIFICATES

         Section 5.01 Distributions Generally.

         (a)      Subject to Section 7.01 respecting the final distribution on
the Certificates, on each Distribution Date the Trustee or the Paying Agent
shall make distributions in accordance with this Article V. Such distributions
shall be made by check mailed to each Certificateholder's address as it appears
on the Certificate Register of the Certificate Registrar or, upon written
request made to the Securities Administrator at least five Business Days prior
to the related Record Date by any Certificateholder owning an aggregate initial
Certificate Principal Amount of at least $1,000,000, or in the case of a Class
of Interest-Only Certificates or Residual Certificate, a Percentage Interest of
not less than 100%, by wire transfer in immediately available funds to an
account specified in the request and at the expense of such Certificateholder;
provided, however, that the final distribution in respect of any Certificate
shall be made only upon presentation and surrender of such Certificate at the
Certificate Registrar's Corporate Trust Office; provided, further, that the
foregoing provisions shall not apply to any Class of Certificates as long as
such Certificate remains a Book-Entry Certificate in which case all payments
made shall be made through the Clearing Agency and its Clearing Agency
Participants. Wire transfers will be made at the expense of the Holder
requesting such wire transfer by deducting a wire transfer fee from the related
distribution. Notwithstanding such final payment of principal of any of the
Certificates, each Residual Certificate will remain

                                       71



outstanding until the termination of each REMIC and the payment in full of all
other amounts due with respect to the Residual Certificates and at such time
such final payment in retirement of any Residual Certificate will be made only
upon presentation and surrender of such Certificate at the Certificate
Registrar's Corporate Trust Office. If any payment required to be made on the
Certificates is to be made on a day that is not a Business Day, then such
payment will be made on the next succeeding Business Day.

         (b)      All distributions or allocations made with respect to the
Certificateholders within each Class on each Distribution Date shall be
allocated among the outstanding Certificates in such Class equally in proportion
to their respective initial Class Principal Amounts or initial Class Notional
Amounts (or Percentage Interests).

         Section 5.02 Distributions from the Distribution Account.

         (a)      Subject to Sections 5.02(b), (c), (k) and (l), on each

and the Senior Certificates other than the Class X Certificates) and the
Mortgage Pools in the aggregate (in the case of the Subordinate Certificates and

         amount of the Interest Distribution Amount that would otherwise be
         payable to the related Pool NAS Component, related Pool Companion
         Component or Class X-B Certificates will (A) in the case of amounts
         otherwise payable to the related Pool NAS Component and related Pool
         Companion Component, be deposited in the related Sub Account of the
         Reserve Fund to the extent of any related Required Reserve Fund Deposit
         for such Distribution Date in the manner described herein, (B) in the
         case of amounts otherwise payable to the related Pool Companion
         Component after the payment of amounts, if any, described in clause (A)
         above, instead be paid to the related Pool NAS Component to the extent
         necessary to reimburse the related Pool NAS Component for any prior
         amounts not distributed to the related Pool NAS Component as a result
         of any reductions on the Interest Distribution Amount of the related
         Pool NAS Component resulting from Interest Shortfalls and (C) in the
         case of amounts otherwise payable to the Class X-B Certificates, be
         deposited in the Class B-1 Sub Account of the Reserve Fund to the
         extent of any Class X-B Required Reserve Fund Deposit for such
         Distribution Date;

                  for such Class and date;

                  Subordinate Class Percentage of the Subordinate Principal

                           (G)      to the Class B-5 Certificates, the Interest
                  Distribution Amount and any Interest Shortfalls, in each case,

         Section 5.02(d).

         (b)      On each Distribution Date on and after the Credit Support
Depletion Date, the Available Distribution Amount for each Mortgage Pool shall
be combined and distributed to the remaining Classes of Certificates, on a pro
rata basis, first, to pay the Interest Distribution Amount and any accrued but

Amounts), until such Certificate Principal Amounts have been reduced to zero;
third, to pay any related Net WAC Shortfall; and fourth, to the Class A-R and
Class LT-R Certificate, any remaining Available Distribution Amount from such

         (c)      Notwithstanding the priority and allocation set forth in
Section 5.02(a)(v) and (x) above, if with respect to any Class of Subordinate
Certificates on any Distribution Date the sum of the related Class Subordination
Percentages of such Class and of all other Classes of Subordinate Certificates
which have a higher numerical Class designation than such Class is less than the
Original Applicable Credit Support Percentage for such Class, no distribution of
Principal Prepayments shall be made to any such Classes and the amount of such
Principal Prepayment otherwise distributable to such Classes shall be
distributed to any Classes of Subordinate Certificates having lower numerical
Class designations than such Class, pro rata, based on the Class Principal
Amounts of the respective Classes immediately prior to such

                                       74



Distribution Date and shall be distributed in the sequential order provided in
Section 5.02(a)(v) and (x) above.

         (d)      Amounts distributed to the Residual Certificates pursuant to
subparagraph (a)(x) of this Section 5.02 on any Distribution Date shall be
allocated among the REMIC residual interests represented thereby such that each
such interest is allocated the excess of funds available to the related REMIC
over required distributions to the regular interests in such REMIC on such
Distribution Date.

         (e)      For purposes of distributions provided in paragraph (a), each
Mortgage Pool shall "relate" to the Senior Class or Classes of the applicable
Related Certificate Group.

         (f)      On any Distribution Date for which a Net WAC Shortfall exists
with respect to the Class A-1 Certificates, the Securities Administrator will
withdraw from the Class A-1 Companion Sub Account and the Class A-1 NAS Sub
Account, in that order, the amount for distribution to such Class equal to the
lesser of (1) the amount of such Net WAC Shortfall and (2) the amounts available
therefor on deposit in the related Sub Account as provided in Section
5.02(a)(vii).

         (g)      On any Distribution Date for which a Net WAC Shortfall exists
with respect to the Class A-2 Certificates, the Securities Administrator will
withdraw from the Class A-2 Companion Sub Account and the Class A-2 NAS Sub
Account, in that order, the amount for distribution to such Class equal to the
lesser of (1) the amount of such Net WAC Shortfall and (2) the amounts available
therefor on deposit in the related Sub Account as provided in Section
5.02(a)(vii).

         (h)      On any Distribution Date for which a Net WAC Shortfall exists
with respect to the Class B-1 Certificates, the Securities Administrator will
withdraw from the Class B-1 Sub Account, the lesser of (1) the amount of such
Net WAC Shortfall and (2) the amounts available therefor on deposit in the
related Sub Account as provided in Section 5.02(a)(vii).

         (i)      On any Distribution Date and with respect to the Class X-1
Certificates, to the extent that any amounts otherwise payable to the Pool 1 NAS
Component or Pool 2 NAS Component, as applicable, are used to make payments of
any related Required Reserve Fund Deposit, the Securities Administrator will
withdraw from the Class A-1 Companion Sub Account or Class A-2 Companion Sub
Account, as applicable, to the extent of amounts on deposit in such Sub Accounts
after withdrawals therefrom to cover any related Net WAC Shortfalls for such
Distribution Date or previous Distribution Dates, the amount of such deposits
for distribution on such Distribution Date as provided in Section 5.06.

         (j)      For purposes of distributions of interest in paragraph (a)
such distributions to a Class of Certificates on any Distribution Date shall be
made first, in respect of Current Interest; and second, in respect of Interest
Shortfalls.

         (k)      Notwithstanding the priority of distributions set forth in
paragraph (a) above, if on any Distribution Date prior to the Credit Support
Depletion (1) either one of the Rapid Prepayment Conditions is satisfied on such
date and (2) the Certificate Principal Amount of the Senior Certificates
relating to one of the Mortgage Pools have been reduced to zero, then that

                                       75



portion of the Available Distribution Amount for each Mortgage Pool described in
Section 5.02(a)(ii) that represents principal collections on the Mortgage Loans
shall be applied as an additional distribution to the remaining Classes of
Senior Certificates in reduction of, and in proportion to, the Class Principal
Amounts thereof; provided, however, that any such amounts distributable to the
Class A-R and Class A-1 Certificates shall be distributed sequentially thereto
in such order.

         (l)      If, on any Distribution Date, any Certificate Group would
constitute an Undercollateralized Group and the other Certificate Group
constitutes an Overcollateralized Group, then notwithstanding Section
5.02(a)(ii), the Available Distribution Amount for the Overcollateralized Group,
to the extent remaining following distributions of interest and principal to the
related Senior Certificates of that Certificate Group, shall be distributed up
to the sum of the Interest Transfer Amount and the Principal Transfer Amount for
the Undercollateralized Group to the Senior Certificates related to the
Undercollateralized Group in payment of accrued but unpaid interest, if any, and
then to such Senior Certificates as principal, in the same order and priority as
such Certificates would receive other distributions of principal.

         (m)      If, immediately after any Distribution Date, the amount on
deposit in any Sub Account of the Reserve Fund exceeds the initial deposit
therein, the Securities Administrator will distribute such excess to the Holders
of the Certificates that deposited such amounts in the relevant Sub Account.

         Section 5.03 Allocation of Losses.

         (a)      On or prior to each Distribution Date, the Master Servicer
shall aggregate the information provided by each Servicer with respect to the
total amount of Realized Losses experienced on the Mortgage Loans for the
related Distribution Date.

         (b)      On each Distribution Date, the principal portion of Realized
Losses shall be allocated as follows:

                  first, to the Classes of Subordinate Certificates in reverse
               order of their respective numerical Class designations (beginning
               with the Class of Subordinate Certificates with the highest
               numerical Class designation) until the Class Principal Amount of
               each such Class is reduced to zero; and

                  second, to each Class of Senior Certificates relating to the
               Mortgage Pool which sustained such loss (allocated among the
               related Senior Classes on a pro rata basis), in each case, until
               the Class Principal Amount of each Class of Senior Certificates
               is reduced to zero;

         (c)      On each Distribution Date, the Class Principal Amount of the
Class of Subordinate Certificates then outstanding with the highest numerical
Class designation shall be reduced on each Distribution Date by the amount, if
any, by which the aggregate of the Class Principal Amounts of all outstanding
Classes of Certificates (after giving effect to the distribution of principal on
such Distribution Date) exceeds the Aggregate Stated Principal Balance for the
following Distribution Date.

                                       76



         (d)      Any allocation of a loss pursuant to this section to a Class
of Certificates shall be achieved by reducing the Class Principal Amount thereof
by the amount of such loss.

         (e)      In the event that there is a recovery of an amount in respect
of principal of a Mortgage Loan, which amount had previously been allocated as a
Realized Loss to one or more Classes of Certificates, each outstanding Class to
which any portion of such Realized Loss had previously been allocated shall be
entitled to receive, on the Distribution Date in the month following the month
in which such recovery is received, its pro rata share (based on the amount of
Realized Losses previously allocated thereto) of such recovery, up to the amount
of the portion of such Realized Loss previously allocated to such Class. Any
such recovery allocated to a Class of Certificates shall not further reduce the
Certificate Principal Amount of such Certificate. Any such amounts not otherwise
allocated to any Class of Certificates pursuant to this subsection shall be
treated as Principal Prepayments for purposes of this Agreement.

         Section 5.04 Advances by Master Servicer.

         If any Servicer fails to remit any Advance required to be made under
the applicable Servicing Agreement, the Master Servicer shall itself make, or
shall cause the successor Servicer to make, such Advance. If the Master Servicer
determines that an Advance is required, it shall on the Business Day preceding
the related Distribution Date immediately following such Determination Date
remit to the Securities Administrator from its own funds (or funds advanced by
the applicable Servicer) for deposit in the Account immediately available funds
in an amount equal to such Advance. The Master Servicer and each Servicer shall
be entitled to be reimbursed for all Advances made by it. Notwithstanding
anything to the contrary herein, in the event the Master Servicer determines in
its reasonable judgment that an Advance is non-recoverable, the Master Servicer
shall be under no obligation to make such Advance. If the Master Servicer
determines that an Advance is non-recoverable, it shall, on or prior to the
related Distribution Date, deliver an Officer's Certificate to the Trustee to
such effect.

         Section 5.05 Compensating Interest Payments.

         The amount of the aggregate Master Servicing Fees payable to the Master
Servicer in respect of any Distribution Date shall be reduced (but not below
zero) by the amount of any Compensating Interest Payment for such Distribution
Date, but only to the extent that Prepayment Interest Shortfalls relating to
such Distribution Date are required to be paid but not actually paid by the
Servicers. Such amount shall not be treated as an Advance and shall not be
reimbursable to the Master Servicer.

         Section 5.06 Reserve Fund.

         (a)      On the Closing Date, the Securities Administrator shall
establish and maintain in the Trustee's name, in trust for the benefit of the
holders of the LIBOR Certificates and the Interest-Only Certificates, a Reserve
Fund, into which the Depositor shall, on such date, deposit $10,000.00. The
Reserve Fund shall be an Eligible Account, and funds on deposit therein shall be
held separate and apart from, and shall not be commingled with, any other
moneys, including, without limitation, other moneys of the Trustee held pursuant
to this Agreement. The Reserve Fund shall not be an asset of any REMIC
established hereby.

                                       77



         (b)      The Reserve Fund will be comprised of five Sub Accounts:
"Class A-1 NAS Sub Account", "Class A-1 Companion Sub Account", "Class A-2 NAS
Sub Account", "Class A-2 Companion Sub Account" and "Class B-1 Sub Account". On
each Distribution Date, (i) Current Interest that would otherwise be
distributable with respect to the Class X-1 Certificates will be deposited
instead in the Class A-1 NAS and Class A-2 NAS Sub Accounts, (ii) Current
Interest that would otherwise be distributable with respect to the Class X-2
Certificates will be deposited instead in the Class A-1 Companion and Class A-2
Companion Sub Accounts and (iii) Current Interest that would otherwise be
distributable with respect to the Class X-B Certificates will be deposited
instead in the Class B-1 Sub Account, in each case, to the extent of the
applicable Required Reserve Fund Deposit for such Class or Component.

         (c)      On any Distribution Date for which a Net WAC Shortfall exists
with respect to the Class A-1 Certificates, the Securities Administrator shall
withdraw, to the extent of available funds therein, from the Class A-1 Companion
Sub Account and the Class A-1 NAS Sub Account, in that order, the amount of such
Net WAC Shortfall for distribution on such Distribution Date pursuant to Section
5.02(f).

         (d)      On any Distribution Date for which a Net WAC Shortfall exists
with respect to the Class A-2 Certificates, the Securities Administrator shall
withdraw, to the extent of available funds therein, from the Class A-2 Companion
Sub Account and the Class A-2 NAS Sub Account, in that order, the amount of such
Net WAC Shortfall for distribution on such Distribution Date pursuant to Section
5.02(g).

         (e)      On any Distribution Date for which a Net WAC Shortfall exists
with respect to the Class B-1 Certificates, the Securities Administrator shall
withdraw, to the extent of available funds therein, from the Class B-1 Sub
Account the amount of such Net WAC Shortfall for distribution on such
Distribution Date pursuant to Section 5.02(h).

         (f)      On any Distribution Date and with respect to the Class X-1
Certificates, to the extent that any amounts otherwise payable to the Pool 1 NAS
Component or Pool 2 NAS Component, as applicable, are used to make payments of
any related Required Reserve Fund Deposit, the Securities Administrator will
withdraw from the Class A-1 Companion Sub Account or Class A-2 Companion Sub
Account, as applicable, to the extent of amounts on deposit in such Sub Accounts
after withdrawals therefrom to cover any related Net WAC Shortfalls for such
Distribution Date or previous Distribution Dates, the amount of such deposits
for distribution on such Distribution Date as provided in Section 5.02(i).

         (g)      Funds in each of the Sub Account shall be invested in
Permitted Investments. Any earnings on amounts in the Class A-1 NAS Sub Account
and Class A-2 NAS Sub Account shall be for the benefit of the Class X-1
Certificateholders; any earnings on amounts in the Class A-1 Companion Sub
Account and Class A-2 Companion Sub Account shall be for the benefit of the
Class X-2 Certificateholders; and any earnings on amounts in the Class B-1 Sub
Account shall be for the benefit of the Class X-B Certificateholders. The
Interest-Only Certificates shall evidence ownership of the related Sub Account
for federal income tax purposes and the Holders thereof shall direct the
Securities Administrator, in writing, as to investment of amounts on deposit
therein. The applicable Interest-Only Certificateholder(s) shall be liable for
any losses incurred on such investments. In the absence of written instructions
from the applicable Interest-Only Certificateholder as to investment of funds on
deposit in the related Sub Account, such

                                       78



funds shall be invested in money market funds as described in paragraph (ix) of
the definition of Permitted Investments in Article I. For all Federal income tax
purposes, amounts transferred by the Upper-Tier REMIC to the Reserve Fund shall
be treated as amounts distributed by the Upper-Tier REMIC to the applicable
Interest-Only Certificateholders.

         (h)      If, immediately after any Distribution Date, the amount on
deposit in any Sub Account of the Reserve Fund exceeds the initial deposit
therein, the Securities Administrator will distribute such excess to the Holders
of the Certificates that deposited such amounts in the relevant Sub Account
pursuant to Section 5.02(m).

         (i)      Upon termination of the Trust Fund any amounts remaining in
the related Sub Account shall be distributed to the applicable Interest-Only
Certificateholders.

                                   ARTICLE VI

   CONCERNING THE TRUSTEE AND THE SECURITIES ADMINISTRATOR; EVENTS OF DEFAULT

         Section 6.01 Duties of Trustee and the Securities Administrator.

         (a)      The Trustee, except during the continuance of an Event of
Default and the Securities Administrator undertakes to perform such duties and
only such duties as are specifically set forth in this Agreement. Any permissive
right of the Trustee or the Securities Administrator provided for in this
Agreement shall not be construed as a duty of the Trustee or the Securities
Administrator. If an Event of Default has occurred and has not otherwise been
cured or waived, the Trustee or the Securities Administrator shall exercise such
of the rights and powers vested in it by this Agreement and use the same degree
of care and skill in their exercise as a prudent Person would exercise or use
under the circumstances in the conduct of such Person's own affairs, unless the
Trustee is acting as Master Servicer, in which case it shall use the same degree
of care and skill as the Master Servicer hereunder.

         (b)      Each of the Trustee and the Securities Administrator, upon
receipt of all resolutions, certificates, statements, opinions, reports,
documents, orders or other instruments furnished to the Trustee or the
Securities Administrator which are specifically required to be furnished
pursuant to any provision of this Agreement, shall examine them to determine
whether they are in the form required by this Agreement; provided, however, that
neither the Trustee nor the Securities Administrator shall be responsible for
the accuracy or content of any such resolution, certificate, statement, opinion,
report, document, order or other instrument furnished by the Master Servicer or
any Servicer to the Trustee or the Securities Administrator pursuant to this
Agreement, and shall not be required to recalculate or verify any numerical
information furnished to the Trustee or the Securities Administrator pursuant to
this Agreement. Subject to the immediately preceding sentence, if any such
resolution, certificate, statement, opinion, report, document, order or other
instrument is found not to conform to the form required by this Agreement in a
material manner the Trustee shall take such action as it deems appropriate to
cause the instrument to be corrected, and if the instrument is not corrected to
the Trustee's satisfaction, the Trustee will provide notice thereof to the
Certificateholders and will, at the expense of the Trust Fund, which expense
shall be reasonable given the scope and nature of the required action, take such
further action as directed by the Certificateholders.

                                       79



         (c)      Neither the Trustee nor the Securities Administrator shall
have any liability arising out of or in connection with this Agreement, except
for its negligence or willful misconduct. Notwithstanding anything in this
Agreement to the contrary, neither the Trustee nor the Securities Administrator
shall be liable for special, indirect or consequential losses or damages of any
kind whatsoever (including, but not limited to, lost profits). No provision of
this Agreement shall be construed to relieve the Trustee or the Securities
Administrator from liability for its own negligent action, its own negligent
failure to act or its own willful misconduct; provided, however, that:

                  (i)      Neither the Trustee nor the Securities Administrator
         shall be personally liable with respect to any action taken, suffered
         or omitted to be taken by it in good faith in accordance with the
         direction of Holders of Certificates as provided in Section 6.18
         hereof;

                  (ii)     For all purposes under this Agreement, the Trustee
         shall not be deemed to have notice of any Event of Default (other than
         resulting from a failure by the Master Servicer (i) to remit funds (or
         to make Advances) or (ii) to furnish information to the Trustee when
         required to do so) unless a Responsible Officer of the Trustee has
         actual knowledge thereof or unless written notice of any event which is
         in fact such a default is received by the Trustee at the Corporate
         Trust Office of the Trustee, and such notice references the Holders of
         the Certificates and this Agreement;

                  (iii)    For all purposes under this Agreement, the Securities
         Administrator shall not be deemed to have notice of any Event of
         Default (other than resulting from a failure by the Master Servicer to
         furnish information to the Securities Administrator when required to do
         so) unless a Responsible Officer of the Securities Administrator has
         actual knowledge thereof or unless written notice of any event which is
         in fact such a default is received by the Securities Administrator at
         the address provided in Section 11.07, and such notice references the
         Holders of the Certificates and this Agreement;

                  (iv)     No provision of this Agreement shall require the
         Trustee or the Securities Administrator to expend or risk its own funds
         or otherwise incur any financial liability in the performance of any of
         its duties hereunder, or in the exercise of any of its rights or
         powers, if it shall have reasonable grounds for believing that
         repayment of such funds or adequate indemnity against such risk or
         liability is not reasonably assured to it; and none of the provisions
         contained in this Agreement shall in any event require the Trustee or
         the Securities Administrator to perform, or be responsible for the
         manner of performance of, any of the obligations of the Master Servicer
         under this Agreement;

                  (v)      Neither the Trustee nor the Securities Administrator
         shall be responsible for any act or omission of the Master Servicer,
         the Depositor, the Seller or any Custodian.

         (d)      The Trustee shall have no duty hereunder with respect to any
complaint, claim, demand, notice or other document it may receive or which may
be alleged to have been delivered to or served upon it by the parties as a
consequence of the assignment of any Mortgage Loan hereunder; provided, however,
that the Trustee shall promptly remit to the applicable Servicer upon receipt
any such complaint, claim, demand, notice or other document (i) which is
delivered to the Corporate Trust Office of the Trustee, (ii) of which a
Responsible Officer has actual

                                       80


knowledge, and (iii) which contains information sufficient to permit the Trustee
to make a determination that the real property to which such document relates is
a Mortgaged Property.

         (e)      Neither the Trustee nor the Securities Administrator shall be
personally liable with respect to any action taken, suffered or omitted to be
taken by it in good faith in accordance with the direction of the
Certificateholders of any Class holding Certificates which evidence, as to such
Class, Percentage Interests aggregating not less than 25% as to the time, method
and place of conducting any proceeding for any remedy available to the Trustee
or the Securities Administrator or exercising any trust or power conferred upon
the Trustee or the Securities Administrator, as applicable, under this
Agreement.

         (f)      Neither the Trustee nor the Securities Administrator shall be
required to perform services under this Agreement, or to expend or risk its own
funds or otherwise incur financial liability for the performance of any of its
duties hereunder or the exercise of any of its rights or powers if there is
reasonable ground for believing that the timely payment of its fees and expenses
or the repayment of such funds or adequate indemnity against such risk or
liability is not reasonably assured to it, and none of the provisions contained
in this Agreement shall in any event require the Trustee or the Securities
Administrator, as applicable, to perform, or be responsible for the manner of
performance of, any of the obligations of the Master Servicer or any Servicer
under this Agreement or any Servicing Agreement except during such time, if any,
as the Trustee shall be the successor to, and be vested with the rights, duties,
powers and privileges of, the Master Servicer in accordance with the terms of
this Agreement.

         (g)      The Trustee shall not be held liable by reason of any
insufficiency in the Distribution Account or the Reserve Fund resulting from any
investment loss on any Permitted Investment included therein (except to the
extent that the Trustee is the obligor and has defaulted thereon).

         (h)      Except as otherwise provided herein, neither the Trustee nor
the Securities Administrator shall have any duty (A) to see to any recording,
filing, or depositing of this Agreement or any agreement referred to herein or
any financing statement or continuation statement evidencing a security
interest, or to see to the maintenance of any such recording or filing or
depositing or to any rerecording, refiling or redepositing of any thereof, (B)
to see to any insurance, (C) to see to the payment or discharge of any tax,
assessment, or other governmental charge or any lien or encumbrance of any kind
owing with respect to, assessed or levied against, any part of the Trust Fund
other than from funds available in the Distribution Account, or (D) to confirm
or verify the contents of any reports or certificates of the Master Servicer or
any Servicer delivered to the Trustee or the Securities Administrator pursuant
to this Agreement believed by the Trustee or the Securities Administrator, as
applicable, to be genuine and to have been signed or presented by the proper
party or parties.

         (i)      Neither the Securities Administrator nor the Trustee shall be
liable in its individual capacity for an error of judgment made in good faith by
a Responsible Officer or other officers of the Trustee or the Securities
Administrator, as applicable, unless it shall be proved that the Trustee or the
Securities Administrator, as applicable, was negligent in ascertaining the
pertinent facts.

                                       81



         (j)      Notwithstanding anything in this Agreement to the contrary,
neither the Securities Administrator nor the Trustee shall be liable for
special, indirect or consequential losses or damages of any kind whatsoever
(including, but not limited to, lost profits), even if the Trustee or the
Securities Administrator, as applicable, has been advised of the likelihood of
such loss or damage and regardless of the form of action.

         (k)      Neither the Securities Administrator nor the Trustee shall be
responsible for the acts or omissions of the other, it being understood that
this Agreement shall not be construed to render them agents of one another.

         refraining from acting upon any resolution, Officer's Certificate,
         certificate of auditors or any other certificate, statement,
         instrument, opinion, report, notice, request, consent, order, approval,

         respect of any action taken or suffered or omitted by it hereunder in
         good faith and in accordance with such advice or Opinion of Counsel;

                  (iii)    Neither the Trustee nor the Securities Administrator

         Agreement;

                  (iv)     Unless an Event of Default shall have occurred and be
         continuing, neither the Trustee nor the Securities Administrator shall
         be bound to make any investigation into the facts or matters stated in
         any resolution, certificate, statement, instrument, opinion, report,
         notice, request, consent, order, approval, bond or other paper or
         document (provided the same appears regular on its face), unless
         requested in writing to do so by the Holders of at least a majority in
         Class Principal Amount (or Percentage Interest) of each Class of
         Certificates; provided, however, that, if the payment within a
         reasonable time to the Trustee or the Securities Administrator, as
         applicable, of the costs, expenses or liabilities likely to be incurred
         by it in the making of such investigation is, in the opinion of the
         Trustee or the Securities Administrator, as applicable, not reasonably
         assured to the Trustee or the Securities Administrator by the security
         afforded to it by the terms of this Agreement, the Trustee or the
         Securities Administrator, as applicable, may require reasonable
         indemnity against such expense or liability or payment of such
         estimated expenses from the Certificateholders as a condition to
         proceeding. The reasonable expense thereof shall be paid by the party

         party shall be reimbursed to the Trustee by the Trust Fund;

                                     82

         may execute any of the trusts or powers hereunder or perform any duties
         hereunder either directly or by or through agents, custodians or
         attorneys, which agents, custodians or attorneys shall have any and all
         of the rights, powers, duties and obligations of the Trustee and the
         Securities Administrator conferred on them by such appointment,
         provided that each of the Trustee and the Securities Administrator
         shall continue to be responsible for its duties and obligations
         hereunder to the extent provided herein, and provided further that
         neither the Trustee nor the Securities Administrator shall be

         litigation hereunder or in relation hereto, in each case at the
         request, order or direction of any of the Certificateholders pursuant
         to the provisions of this Agreement, unless such Certificateholders
         shall have offered to the Trustee or the Securities Administrator, as
         applicable, reasonable security or indemnity against the costs,
         expenses and liabilities which may be incurred therein or thereby;

                  (vii)    The right of the Trustee and the Securities

         negligence or willful misconduct in the performance of such act; and

                  (viii)   Neither the Trustee nor the Securities Administrator

         Section 6.03 Trustee and Securities Administrator Not Liable for
                      Certificates.

         The Trustee and the Securities Administrator make no representations as
to the validity or sufficiency of this Agreement or of the Certificates (other
than the certificate of authentication on the Certificates) or of any Mortgage
Loan, or related document save that the Trustee and the Securities Administrator
represent that, assuming due execution and delivery by the other parties hereto,
this Agreement has been duly authorized, executed and delivered by it and
constitutes its valid and binding obligation, enforceable against it in
accordance with its terms except that such enforceability may be subject to (A)
applicable bankruptcy and insolvency laws and other similar laws affecting the
enforcement of the rights of creditors generally, and (B) general principles of
equity regardless of whether such enforcement is considered in a proceeding in

other parties hereto and their Affiliates with the same rights it would have if
it were not Trustee, Securities Administrator or such agent.

examination by federal or state authority and (iii) not an Affiliate of the
Master Servicer or any Servicer. If such corporation or national banking
association publishes reports of condition at least annually, pursuant to law or

published. In case at any time the Trustee shall cease to be eligible in

Trustee or resigning Securities Administrator, as applicable, may petition any
court of competent jurisdiction for the appointment of a successor trustee or

or insolvent, or a receiver of the Trustee or the Securities Administrator of
its property shall be appointed, or any public officer shall take charge or
control of the Trustee or the Securities Administrator or of either of their
property or affairs for the purpose of rehabilitation, conservation or
liquidation, (iii) a tax is imposed or threatened with respect to the Trust Fund
by any state in which the Trustee or the Trust Fund held by the Trustee is
located, or

                                       84



(iv) the continued use of the Trustee or Securities Administrator would result
in a downgrading of the rating by any Rating Agency of any Class of Certificates

trustee or successor securities administrator, as applicable, acceptable to the
Master Servicer by written instrument, one copy of which instrument shall be
delivered to the Trustee or Securities Administrator so removed, one copy each

written notice to the Trustee or the Securities Administrator, as applicable,
and to the Depositor remove the Trustee or the Securities Administrator, as
applicable, by such written instrument, signed by such Holders or their
attorney-in-fact duly authorized, one copy of which instrument shall be
delivered to the Depositor, one copy to the Trustee or Securities Administrator,
as applicable and one copy to the Master Servicer; the Depositor shall thereupon
appoint a successor trustee or successor securities administrator, as
applicable, in accordance with this Section.

         (d)      Any resignation or removal of the Trustee or the Securities
Administrator, as applicable, and appointment of a successor trustee or
successor securities administrator pursuant to any of the provisions of this
Section shall become effective upon acceptance of appointment by the successor
trustee or the successor securities administrator, as applicable, as provided in

appointed as provided in Section 6.06 shall execute, acknowledge and deliver to
the Depositor and to its predecessor trustee or predecessor securities
administrator, as applicable, an instrument accepting such appointment
hereunder, and thereupon the resignation or removal of the predecessor trustee
or predecessor securities administrator, as applicable, shall become effective
and such successor trustee or successor securities administrator, as applicable,
without any further act, deed or conveyance, shall become fully vested with all
the rights, powers, duties and obligations of its predecessor hereunder, with
like effect as if originally named as trustee or securities administrator, as
applicable, herein. The predecessor trustee or predecessor securities
administrator, as applicable, shall deliver to the successor trustee (or assign
to the Trustee its interest under the Custody Agreements, to the extent
permitted thereunder) or successor securities administrator, as applicable, all

pay over to the successor trustee the entire Trust Fund, together with all
necessary instruments of transfer and assignment or other documents properly
executed necessary to effect such transfer and such of the records or copies
thereof maintained by the predecessor trustee in the administration hereof as
may be requested by the successor trustee and shall thereupon be discharged from
all duties and responsibilities under this Agreement. In addition, the Depositor
and the predecessor trustee or predecessor securities administrator, as
applicable, shall execute and deliver such other instruments and do such other
things as may reasonably be required to more fully and certainly vest and
confirm in the successor trustee or successor securities administrator, as
applicable, all such rights, powers, duties and obligations.

                                       85



         (b)      No successor trustee shall accept appointment as provided in
this Section unless at the time of such appointment such successor trustee shall
be eligible under the provisions of Section 6.05.

         (c)      Upon acceptance of appointment by a successor trustee or
successor securities administrator, as applicable, as provided in this Section,
the predecessor trustee or predecessor securities administrator, as applicable,
shall mail notice of the succession of such trustee or securities administrator,
as applicable, hereunder to all Holders of Certificates at their addresses as
shown in the Certificate Register and to any Rating Agency. The expenses of such
mailing shall be borne by the Master Servicer.

         Section 6.08 Merger or Consolidation of Trustee or the Securities
                      Administrator.

         Any Person into which the Trustee or Securities Administrator may be
merged or with which it may be consolidated, or any Person resulting from any
merger, conversion or consolidation to which the Trustee or Securities
Administrator shall be a party, or any Persons succeeding to the business of the
Trustee or Securities Administrator, shall be the successor to the Trustee or
Securities Administrator hereunder, without the execution or filing of any paper
or any further act on the part of any of the parties hereto, anything herein to
the contrary notwithstanding, provided that, in the case of the Trustee, such
Person shall be eligible under the provisions of Section 6.05.

         Section 6.09 Appointment of Co-Trustee, Separate Trustee or Custodian.

         (a)      Notwithstanding any other provisions hereof, at any time, the
Trustee, the Depositor or the Certificateholders evidencing more than 50% of the
Class Principal Amount (or Percentage Interest) of every Class of Certificates
shall have the power from time to time to appoint one or more Persons, approved
by the Trustee, to act either as co-trustees jointly with the Trustee, or as
separate trustees, or as custodians, for the purpose of holding title to,
foreclosing or otherwise taking action with respect to any Mortgage Loan outside
the state where the Trustee has its principal place of business where such
separate trustee or co-trustee is necessary or advisable (or the Trustee has
been advised by the Master Servicer that such separate trustee or co-trustee is
necessary or advisable) under the laws of any state in which a property securing
a Mortgage Loan is located or for the purpose of otherwise conforming to any
legal requirement, restriction or condition in any state in which a property
securing a Mortgage Loan is located or in any state in which any portion of the
Trust Fund is located. The separate Trustees, co-trustees, or custodians so
appointed shall be trustees or custodians for the benefit of all the
Certificateholders and shall have such powers, rights and remedies as shall be
specified in the instrument of appointment; provided, however, that no such
appointment shall, or shall be deemed to, constitute the appointee an agent of
the Trustee. The obligation of the Master Servicer to make Advances pursuant to
Section 5.04 hereof shall not be affected or assigned by the appointment of a
co-trustee.

         (b)      Every separate trustee, co-trustee, and custodian shall, to
the extent permitted by law, be appointed and act subject to the following
provisions and conditions:

                                       86



                  (i)      all powers, duties, obligations and rights conferred
         upon the Trustee in respect of the receipt, custody and payment of
         moneys shall be exercised solely by the Trustee;

                  (ii)     all other rights, powers, duties and obligations
         conferred or imposed upon the Trustee shall be conferred or imposed
         upon and exercised or performed by the Trustee and such separate
         trustee, co-trustee, or custodian jointly, except to the extent that
         under any law of any jurisdiction in which any particular act or acts
         are to be performed the Trustee shall be incompetent or unqualified to
         perform such act or acts, in which event such rights, powers, duties
         and obligations, including the holding of title to the Trust Fund or
         any portion thereof in any such jurisdiction, shall be exercised and
         performed by such separate trustee, co-trustee, or custodian;

                  (iii)    no trustee or custodian hereunder shall be personally
         liable by reason of any act or omission of any other trustee or
         custodian hereunder; and

                  (iv)     the Trustee may at any time, by an instrument in
         writing executed by it, with the concurrence of the Depositor, accept
         the resignation of or remove any separate trustee, co-trustee or
         custodian, so appointed by it or them, if such resignation or removal
         does not violate the other terms of this Agreement.

         (c)      Any notice, request or other writing given to the Trustee
shall be deemed to have been given to each of the then separate trustees and
co-trustees, as effectively as if given to each of them. Every instrument
appointing any separate trustee, co-trustee or custodian shall refer to this
Agreement and the conditions of this Article VI. Each separate trustee and
co-trustee, upon its acceptance of the trusts conferred, shall be vested with
the estates or property specified in its instrument of appointment, either
jointly with the Trustee or separately, as may be provided therein, subject to
all the provisions of this Agreement, specifically including every provision of
this Agreement relating to the conduct of, affecting the liability of, or
affording protection to, the Trustee. Every such instrument shall be filed with
the Trustee and a copy given to the Master Servicer.

         (d)      Any separate trustee, co-trustee or custodian may, at any
time, constitute the Trustee its agent or attorney-in-fact with full power and
authority, to the extent not prohibited by law, to do any lawful act under or in
respect of this Agreement on its behalf and in its name. If any separate
trustee, co-trustee or custodian shall die, become incapable of acting, resign
or be removed, all of its estates, properties, rights, remedies and trusts shall
vest in and be exercised by the Trustee, to the extent permitted by law, without
the appointment of a new or successor trustee.

         (e)      No separate trustee, co-trustee or custodian hereunder shall
be required to meet the terms of eligibility as a successor trustee under
Section 6.05 hereunder and no notice to the Certificateholders of the
appointment shall be required under Section 6.07 hereof.

         (f)      The Trustee agrees to instruct the co-trustees, if any, to the
extent necessary to fulfill the Trustee's obligations hereunder.

                                       87



         (g)      The Trust shall pay the reasonable compensation of the
co-trustees (which compensation shall not reduce any compensation payable to the
Trustee under such Section).

         Section 6.10 Authenticating Agents.

         (a)      The Trustee may appoint one or more Authenticating Agents
which shall be authorized to act on behalf of the Trustee in authenticating
Certificates. The Trustee hereby appoints the Securities Administrator as
initial Authenticating Agent, and the Securities Administrator accepts such
appointment. Wherever reference is made in this Agreement to the authentication
of Certificates by the Trustee or the Trustee's certificate of authentication,
such reference shall be deemed to include authentication on behalf of the
Trustee by an Authenticating Agent and a certificate of authentication executed
on behalf of the Trustee by an Authenticating Agent. Each Authenticating Agent
must be a corporation organized and doing business under the laws of the United
States of America or of any state, having a combined capital and surplus of at
least $15,000,000, authorized under such laws to do a trust business and subject
to supervision or examination by federal or state authorities.

         (b)      Any Person into which any Authenticating Agent may be merged
or converted or with which it may be consolidated, or any Person resulting from
any merger, conversion or consolidation to which any Authenticating Agent shall
be a party, or any Person succeeding to the corporate agency business of any
Authenticating Agent, shall continue to be the Authenticating Agent without the
execution or filing of any paper or any further act on the part of the Trustee
or the Authenticating Agent.

         (c)      Any Authenticating Agent may at any time resign by giving at
least 30 days' advance written notice of resignation to the Trustee and the
Depositor. The Trustee may at any time terminate the agency of any
Authenticating Agent by giving written notice of termination to such
Authenticating Agent and the Depositor. Upon receiving a notice of resignation
or upon such a termination, or in case at any time any Authenticating Agent
shall cease to be eligible in accordance with the provisions of this Section
6.10, the Trustee may appoint a successor authenticating agent, shall give
written notice of such appointment to the Depositor and shall mail notice of
such appointment to all Holders of Certificates. Any successor authenticating
agent upon acceptance of its appointment hereunder shall become vested with all
the rights, powers, duties and responsibilities of its predecessor hereunder,
with like effect as if originally named as Authenticating Agent. No successor
authenticating agent shall be appointed unless eligible under the provisions of
this Section 6.10. No Authenticating Agent shall have responsibility or
liability for any action taken by it as such at the direction of the Trustee.

         Section 6.11 Indemnification of the Trustee and the Securities
                      Administrator.

         The Trustee and the Securities Administrator and their respective
directors, officers, employees and agents shall be entitled to indemnification
from the Depositor and the Trust Fund (provided that the Trust Fund's
indemnification under this Section 6.11 is limited by Section 4.01(d) for any
loss, liability or expense (including, without limitation, reasonable attorneys'
fees and disbursements (and, in the case of the Trustee, in connection with the
Custody Agreements, including the reasonable compensation and the expenses and
disbursements of its agents or counsel), incurred without negligence or willful
misconduct on their part, arising out of, or in connection

                                       88



with, the acceptance or administration of the trusts created hereunder or in
connection with the performance of their duties hereunder including the costs
and expenses of defending themselves against any claim in connection with the
exercise or performance of any of their powers or duties hereunder, provided
that:

                  (i)      with respect to any such claim, the Trustee or the
         Securities Administrator, as applicable, shall have given the Depositor
         written notice thereof promptly after the Trustee, the Securities
         Administrator, as applicable, shall have knowledge thereof;

                  (ii)     while maintaining control over its own defense, the
         Trustee or the Securities Administrator, as applicable, shall cooperate
         and consult fully with the Depositor in preparing such defense; and

                  (iii)    notwithstanding anything to the contrary in this
         Section 6.11, the Trust Fund shall not be liable for settlement of any
         such claim by the Trustee or the Securities Administrator, as
         applicable, entered into without the prior consent of the Depositor,
         which consent shall not be unreasonably withheld.

         The provisions of this Section 6.11 shall survive any termination of
this Agreement and the resignation or removal of the Trustee or the Securities
Administrator, as applicable, and shall be construed to include, but not be
limited to any loss, liability or expense under any environmental law.

         Section 6.12 Fees and Expenses of Securities Administrator and the
                      Trustee.

         (a)      Compensation for the services of the Securities Administrator
hereunder shall be paid by the Master Servicer. The Securities Administrator
shall be entitled to all disbursements and advancements incurred or made by the
Securities Administrator in accordance with this Agreement (including fees and
expenses of its counsel and all persons not regularly in its employment), except
any such expenses arising from its negligence, bad faith or willful misconduct.

         (b)      As compensation for its services hereunder, the Trustee shall
be entitled to receive a Trustee fee (which shall not be limited by any
provision of law in regard to the compensation of a trustee of an express trust)
which shall be paid by the Master Servicer pursuant to a separate agreement
between the Trustee and the Master Servicer. Any expenses incurred by the
Trustee shall be reimbursed in accordance with Section 6.11.

         Section 6.13 Collection of Monies.

         Except as otherwise expressly provided in this Agreement, the Trustee
may demand payment or delivery of, and shall receive and collect, all money and
other property payable to or receivable by the Trustee pursuant to this
Agreement. The Trustee shall hold all such money and property received by it as
part of the Trust Fund and shall distribute it as provided in this Agreement.

                                       89



         Section 6.14 Events of Default; Trustee To Act; Appointment of
                      Successor.

         (a)      The occurrence of any one or more of the following events
shall constitute an "Event of Default":

                  (i)      Any failure by the Master Servicer to furnish the
         Securities Administrator the Mortgage Loan data sufficient to prepare
         the reports described in Section 4.04 which continues unremedied for a
         period of one Business Day after the date upon which written notice of
         such failure shall have been given to such Master Servicer by the
         Trustee or the Securities Administrator or to such Master Servicer, the
         Securities Administrator and the Trustee by the Holders of not less
         than 25% of the Class Principal Amount (or Class Notional Amount) of
         each Class of Certificates affected thereby; or

                  (ii)     Any failure on the part of the Master Servicer duly
         to observe or perform in any material respect any other of the
         covenants or agreements (other than those referred to in (viii) and
         (ix) below) on the part of the Master Servicer contained in this
         Agreement which continues unremedied for a period of 30 days after the
         date on which written notice of such failure, requiring the same to be
         remedied, shall have been given to the Master Servicer by the Trustee
         or the Securities Administrator, or to the Master Servicer, the
         Securities Administrator and the Trustee by the Holders of more than
         50% of the Aggregate Voting Interests of the Certificates; or

                  (iii)    A decree or order of a court or agency or supervisory
         authority having jurisdiction for the appointment of a conservator or
         receiver or liquidator in any insolvency, readjustment of debt,
         marshalling of assets and liabilities or similar proceedings, or for
         the winding-up or liquidation of its affairs, shall have been entered
         against the Master Servicer, and such decree or order shall have
         remained in force undischarged or unstayed for a period of 60 days or
         any Rating Agency reduces or withdraws or threatens to reduce or
         withdraw the rating of the Certificates because of the financial
         condition or loan servicing capability of such Master Servicer; or

                  (iv)     The Master Servicer shall consent to the appointment
         of a conservator or receiver or liquidator in any insolvency,
         readjustment of debt, marshalling of assets and liabilities, voluntary
         liquidation or similar proceedings of or relating to the Master
         Servicer or of or relating to all or substantially all of its property;
         or

                  (v)      The Master Servicer shall admit in writing its
         inability to pay its debts generally as they become due, file a
         petition to take advantage of any applicable insolvency or
         reorganization statute, make an assignment for the benefit of its
         creditors or voluntarily suspend payment of its obligations; or

                  (vi)     The Master Servicer shall be dissolved, or shall
         dispose of all or substantially all of its assets, or consolidate with
         or merge into another entity or shall permit another entity to
         consolidate or merge into it, such that the resulting entity does not
         meet the criteria for a successor servicer as specified in Section 9.05
         hereof; or

                  (vii)    If a representation or warranty set forth in Section
         9.03 hereof shall prove to be incorrect as of the time made in any
         respect that materially and adversely affects the

                                       90



         interests of the Certificateholders, and the circumstance or condition
         in respect of which such representation or warranty was incorrect shall
         not have been eliminated or cured within 30 days after the date on
         which written notice of such incorrect representation or warranty shall
         have been given to the Master Servicer by the Trustee or the Securities
         Administrator, or to the Master Servicer, the Securities Administrator
         and the Trustee by the Holders of more than 50% of the Aggregate Voting
         Interests of the Certificates; or

                  (viii)   A sale or pledge of any of the rights of the Master
         Servicer hereunder or an assignment of this Agreement by the Master
         Servicer or a delegation of the rights or duties of the Master Servicer
         hereunder shall have occurred in any manner not otherwise permitted
         hereunder and without the prior written consent of the Trustee and
         Certificateholders holding more than 50% of the Aggregate Voting
         Interests of the Certificates; or

                  (ix)     After receipt of notice from the Trustee, any failure
         of the Master Servicer to make any Advances required to be made
         hereunder.

         If an Event of Default described in clauses (i) through (ix) of this
Section shall occur, then, in each and every case, subject to applicable law, so
long as any such Event of Default shall not have been remedied within any period
of time prescribed by this Section, the Trustee, by notice in writing to the
Master Servicer may, and shall, if so directed by Certificateholders evidencing
more than 50% of the Class Principal Amount (or Class Notional Amount) of each
Class of Certificates, terminate all of the rights and obligations of the Master
Servicer hereunder and in and to the Mortgage Loans and the proceeds thereof. On
or after the receipt by the Master Servicer of such written notice, all
authority and power of the Master Servicer, and only in its capacity as Master
Servicer under this Agreement, whether with respect to the Mortgage Loans or
otherwise, shall pass to and be vested in the Trustee; and the Trustee is hereby
authorized and empowered to execute and deliver, on behalf of the defaulting
Master Servicer as attorney-in-fact or otherwise, any and all documents and
other instruments, and to do or accomplish all other acts or things necessary or
appropriate to effect the purposes of such notice of termination, whether to
complete the transfer and endorsement or assignment of the Mortgage Loans and
related documents or otherwise. The defaulting Master Servicer agrees to
cooperate with the Trustee and the Securities Administrator in effecting the
termination of the defaulting Master Servicer's responsibilities and rights
hereunder as Master Servicer including, without limitation, notifying Servicers
of the assignment of the master servicing function and providing the Trustee or
its designee all documents and records in electronic or other form reasonably
requested by it to enable the Trustee or its designee to assume the defaulting
Master Servicer's functions hereunder and the transfer to the Trustee for
administration by it of all amounts which shall at the time be or should have
been deposited by the defaulting Master Servicer in the Distribution Account and
any other account or fund maintained with respect to the Certificates or
thereafter received with respect to the Mortgage Loans. The Master Servicer
being terminated shall bear all costs of a master servicing transfer, including
but not limited to those of the Trustee or Securities Administrator reasonably
allocable to specific employees and overhead, legal fees and expenses,
accounting and financial consulting fees and expenses, and costs of amending the
Agreement, if necessary.

                                       91



         Notwithstanding the termination of its activities as Master Servicer,
each terminated Master Servicer shall continue to be entitled to reimbursement
under this Agreement to the extent such reimbursement relates to the period
prior to such Master Servicer's termination.

         If any Event of Default shall occur, the Trustee, upon becoming aware
of the occurrence thereof, shall promptly notify the Securities Administrator
and each Rating Agency of the nature and extent of such Event of Default. The
Trustee or the Securities Administrator shall immediately give written notice to
the Master Servicer upon the Master Servicer's failure to make Advances as
required under this Agreement.

         (b)      On and after the time the Master Servicer receives a notice of
termination from the Trustee pursuant to Section 6.14(a) or the Trustee receives
the resignation of the Master Servicer evidenced by an Opinion of Counsel
pursuant to Section 9.06, the Trustee, unless another master servicer shall have
been appointed, shall be the successor in all respects to the Master Servicer in
its capacity as such under this Agreement and the transactions set forth or
provided for herein and shall have all the rights and powers and be subject to
all the responsibilities, duties and liabilities relating thereto and arising
thereafter placed on the Master Servicer hereunder, including the obligation to
make Advances; provided, however, that any failure to perform such duties or
responsibilities caused by the Master Servicer's failure to provide information
required by this Agreement shall not be considered a default by the Trustee
hereunder. In addition, the Trustee shall have no responsibility for any act or
omission of the Master Servicer prior to the issuance of any notice of
termination. The Trustee shall have no liability relating to the representations
and warranties of the Master Servicer set forth in Section 9.03. In the
Trustee's capacity as such successor, the Trustee shall have the same
limitations on liability herein granted to the Master Servicer. As compensation
therefor, the Trustee shall be entitled to receive all compensation payable to
the Master Servicer under this Agreement, including the Master Servicing Fee.

         (c)      Notwithstanding the above, the Trustee may, if it shall be
unwilling to continue to so act, or shall, if it is unable to so act, petition a
court of competent jurisdiction to appoint, or appoint on its own behalf any
established housing and home finance institution servicer, master servicer,
servicing or mortgage servicing institution having a net worth of not less than
$15,000,000 and meeting such other standards for a successor master servicer as
are set forth in this Agreement, as the successor to such Master Servicer in the
assumption of all of the responsibilities, duties or liabilities of a master
servicer, like the Master Servicer. Any entity designated by the Trustee as a
successor master servicer may be an Affiliate of the Trustee; provided, however,
that, unless such Affiliate meets the net worth requirements and other standards
set forth herein for a successor master servicer, the Trustee, in its individual
capacity shall agree, at the time of such designation, to be and remain liable
to the Trust Fund for such Affiliate's actions and omissions in performing its
duties hereunder. In connection with such appointment and assumption, the
Trustee may make such arrangements for the compensation of such successor out of
payments on Mortgage Loans as it and such successor shall agree; provided,
however, that no such compensation shall be in excess of that permitted to the
Master Servicer hereunder. The Trustee and such successor shall take such
actions, consistent with this Agreement, as shall be necessary to effectuate any
such succession and may make other arrangements with respect to the servicing to
be conducted hereunder which are not inconsistent herewith. The Master Servicer
shall cooperate with the Trustee and any successor master

                                       92



servicer in effecting the termination of the Master Servicer's responsibilities
and rights hereunder including, without limitation, notifying Mortgagors of the
assignment of the master servicing functions and providing the Trustee and
successor master servicer, as applicable, all documents and records in
electronic or other form reasonably requested by it to enable it to assume the
Master Servicer's functions hereunder and the transfer to the Trustee or such
successor master servicer, as applicable, all amounts which shall at the time be
or should have been deposited by the Master Servicer in the Distribution Account
and any other account or fund maintained with respect to the Certificates or
thereafter be received with respect to the Mortgage Loans. Neither the Trustee
nor any other successor master servicer shall be deemed to be in default
hereunder by reason of any failure to make, or any delay in making, any
distribution hereunder or any portion thereof caused by (i) the failure of the
Master Servicer to deliver, or any delay in delivering, cash, documents or
records to it, (ii) the failure of the Master Servicer to cooperate as required
by this Agreement, (iii) the failure of the Master Servicer to deliver the
Mortgage Loan data to the Trustee as required by this Agreement or (iv)
restrictions imposed by any regulatory authority having jurisdiction over the
Master Servicer. No successor master servicer shall be deemed to be in default
hereunder by reason of any failure to make, or any delay in making, any
distribution hereunder or any portion thereof caused by (i) the failure of the
Trustee to deliver, or any delay in delivering cash, documents or records to it
related to such distribution, or (ii) the failure of Trustee to cooperate as
required by this Agreement.

         Section 6.15 Additional Remedies of Trustee Upon Event of Default.

         During the continuance of any Event of Default, so long as such Event
of Default shall not have been remedied, the Trustee, in addition to the rights
specified in Section 6.14, shall have the right, in its own name and as trustee
of the Trust Fund, to take all actions now or hereafter existing at law, in
equity or by statute to enforce its rights and remedies and to protect the
interests, and enforce the rights and remedies, of the Certificateholders
(including the institution and prosecution of all judicial, administrative and
other proceedings and the filings of proofs of claim and debt in connection
therewith). Except as otherwise expressly provided in this Agreement, no remedy
provided for by this Agreement shall be exclusive of any other remedy, and each
and every remedy shall be cumulative and in addition to any other remedy, and no
delay or omission to exercise any right or remedy shall impair any such right or
remedy or shall be deemed to be a waiver of any Event of Default.

         Section 6.16 Waiver of Defaults.

         More than 50% of the Aggregate Voting Interests of the
Certificateholders may waive any default or Event of Default by the Master
Servicer in the performance of its obligations hereunder, except that a default
in the making of any required deposit to the Distribution Account that would
result in a failure of the Trustee to make any required payment of principal of
or interest on the Certificates may only be waived with the consent of 100% of
the affected Certificateholders. Upon any such waiver of a past default, such
default shall cease to exist, and any Event of Default arising therefrom shall
be deemed to have been remedied for every purpose of this Agreement. No such
waiver shall extend to any subsequent or other default or impair any right
consequent thereon except to the extent expressly so waived.

                                       93



         Section 6.17 Notification to Holders.

         Upon termination of the Master Servicer or appointment of a successor
to the Master Servicer, in each case as provided herein, the Trustee shall
promptly mail notice thereof by first class mail to the Securities
Administrator, and the Certificateholders at their respective addresses
appearing on the Certificate Register. The Trustee shall also, within 45 days
after the occurrence of any Event of Default known to the Trustee, give written
notice thereof to the Securities Administrator and the Certificateholders,
unless such Event of Default shall have been cured or waived prior to the
issuance of such notice and within such 45-day period.

         Section 6.18 Directions by Certificateholders and Duties of Trustee
                      During Event of Default.

         Subject to the provisions of Section 8.01 hereof, during the
continuance of any Event of Default, Holders of Certificates evidencing not less
than 25% of the Class Principal Amount (or Percentage Interest) of each Class of
Certificates affected thereby may direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee, or exercising
any trust or power conferred upon the Trustee, under this Agreement; provided,
however, that the Trustee shall be under no obligation to pursue any such
remedy, or to exercise any of the trusts or powers vested in it by this
Agreement (including, without limitation, (i) the conducting or defending of any
administrative action or litigation hereunder or in relation hereto and (ii) the
terminating of the Master Servicer or any successor master servicer from its
rights and duties as master servicer hereunder) at the request, order or
direction of any of the Certificateholders, unless such Certificateholders shall
have offered to the Trustee reasonable security or indemnity against the cost,
expenses and liabilities which may be incurred therein or thereby; and, provided
further, that, subject to the provisions of Section 8.01, the Trustee shall have
the right to decline to follow any such direction if the Trustee, in accordance
with an Opinion of Counsel, determines that the action or proceeding so directed
may not lawfully be taken or if the Trustee in good faith determines that the
action or proceeding so directed would involve it in personal liability for
which it is not indemnified to its satisfaction or be unjustly prejudicial to
the non-assenting Certificateholders.

         Section 6.19 Action Upon Certain Failures of the Master Servicer and
                      Upon Event of Default.

         In the event that the Trustee shall have actual knowledge of any action
or inaction of the Master Servicer that would become an Event of Default upon
the Master Servicer's failure to remedy the same after notice, the Trustee shall
give notice thereof to the Master Servicer.

         Section 6.20 Preparation of Tax Returns and Other Reports.

         (a)      The Securities Administrator shall prepare or cause to be
prepared on behalf of the Trust Fund, based upon information calculated in
accordance with this Agreement pursuant to instructions given by the Depositor,
and the Securities Administrator shall file federal tax returns, all in
accordance with Article X hereof. If the Trustee notifies the Securities
Administrator in writing that a state tax return or other return is required,
then, at the sole expense of the Trust Fund, the Securities Administrator shall
prepare and file such state income tax returns and such other returns as may be
required by applicable law relating to the Trust

                                       94



Fund, and, if required by state law, and shall file any other documents to the
extent required by applicable state tax law (to the extent such documents are in
the Securities Administrator's possession). The Securities Administrator shall
forward copies to the Depositor of all such returns and Form 1099 supplemental
tax information and such other information within the control of the Securities
Administrator as the Depositor may reasonably request in writing, and shall
forward to the Trustee for distribution to each Certificateholder such forms and
furnish such information within the control of the Securities Administrator as
are required by the Code and the REMIC Provisions to be furnished to them, and
will prepare and disseminate to the Trustee for distribution to
Certificateholders Form 1099 (supplemental tax information) (or otherwise
furnish information within the control of the Securities Administrator and the
Trustee) to the extent required by applicable law. The Master Servicer will
indemnify the Securities Administrator and the Trustee for any liability of or
assessment against the Securities Administrator and the Trustee, as applicable,
resulting from any error in any of such tax or information returns directly
resulting from errors in the information provided by such Master Servicer.

         (b)      The Securities Administrator shall prepare and file with the
Internal Revenue Service ("IRS"), on behalf of the Trust Fund and each REMIC
created hereunder, an application for an employer identification number on IRS
Form SS-4 or by any other acceptable method. The Securities Administrator shall
also file a Form 8811 as required. The Securities Administrator, upon receipt
from the IRS of the Notice of Taxpayer Identification Number Assigned, shall
upon request promptly forward a copy of such notice to the Trustee and the
Depositor. The Securities Administrator shall furnish any other information that
is required by the Code and regulations thereunder to be made available to the
Certificateholders. The Master Servicer shall cause each Servicer to provide the
Securities Administrator with such information as is necessary for the
Securities Administrator to prepare such reports.

         (c)      Within 15 days after each Distribution Date, the Depositor
shall, on behalf of the Trust and in accordance with industry standards, file
with the Securities and Exchange Commission (the "Commission") via the
Electronic Data Gathering and Retrieval System (EDGAR), a Form 8-K with a copy
of the report to the Certificateholders for such Distribution Date as an exhibit
thereto. Prior to March 30, 2004 (and, if applicable, prior to March 30 of each
year), the Depositor shall, on behalf of the Trust and in accordance with
industry standards, file with the Commission via EDGAR a Form 10-K with respect
to the Trust Fund. In addition, the Depositor will cause its senior officer in
charge of securitization to execute the certification (the "Form 10-K
Certification") required pursuant to Rule 13a-14 under the Securities Exchange
Act of 1934, as amended, and to file the same with the Commission prior to March
30, 2004 (and, if applicable, prior to March 30 of each year). To the extent any
information or exhibits required to be included in the Form 10-K are not
available by March 30, the Depositor shall, on behalf of the Trust, file one or
more amended Form 10-Ks to include such missing information or exhibits promptly
after receipt thereof by the Depositor. Promptly following the first date
legally permissible under applicable regulations and interpretations of the
Commission, the Depositor shall, on behalf of the Trust and in accordance with
industry standards, file with the Commission via EDGAR a Form 15 Suspension
Notification with respect to the Trust Fund, if applicable. Each of the
Securities Administrator, the Master Servicer and the Trustee agree to furnish
to the Depositor promptly, from time to time upon request, such further
information, reports and financial statements within its control related to this
Agreement and the Mortgage Loans as the

                                       95



Depositor reasonably deems appropriate to prepare and file all necessary reports
with the Commission. The Depositor shall have no responsibility to file any
items other than those specified in this section.

         (d)      On or before January 31 of each year, the Depositor, on behalf
of the Trust, shall provide the Securities Administrator with a written notice
listing all Distribution Date reports to the Certificateholders with respect to
Distribution Dates occurring in the prior calendar year that were included in a
Form 8-K filing pursuant to Section 6.20(c); provided that, if no Form 10-K is
required to be filed for such prior calendar year, no written notice shall be
required. No later than March 15 of each year in which such written notice is
provided by the Depositor to the Securities Administrator, the Securities
Administrator shall sign a certification (in the form attached hereto as Exhibit
M), for the benefit of the Person(s) signing the Form 10-K Certification,
regarding certain aspects of the Form 10-K Certification.

                                   ARTICLE II

                         PURCHASE OF MORTGAGE LOANS AND
                          TERMINATION OF THE TRUST FUND

         Section 7.01 Purchase of Mortgage Loans; Termination of Trust Fund
                      Upon Purchase or Liquidation of All Mortgage Loans.

         (a)      The respective obligations and responsibilities of the
Trustee, the Securities Administrator and the Master Servicer created hereby
(other than the obligation of the Securities Administrator to make payments to
the Certificateholders as set forth in Section 7.02), shall terminate on the
earliest of (i) the final payment or other liquidation of the last Mortgage Loan
remaining in the Trust Fund and the disposition of all REO Property, (ii) the
sale of the property held by the Trust Fund in accordance with Section 7.01(b)
(if the Holder of the Class LT-R Certificate chooses to sell the assets of the
Trust Fund in connection with the redemption of the Certificates) or Section
7.01(c) and (iii) the Latest Possible Maturity Date; provided, however, that in
no event shall the Trust Fund created hereby continue beyond the expiration of
21 years from the death of the last survivor of the descendants of Joseph P.
Kennedy, the late Ambassador of the United States to the Court of St. James's,
living on the date hereof. Any termination of the Trust Fund shall be carried
out in such a manner so that the termination of each REMIC included therein
shall qualify as a "qualified liquidation" under the REMIC Provisions.

         (b)      The Certificates shall be subject to optional redemption by
the Holder of the Class LT-R Certificate, in whole but not in part, on any
Distribution Date on or after the date on which the Aggregate Stated Principal
Balance is equal to or less than 20% of the Cut-off Date Balance. If the Holder
of the Class LT-R Certificate elects to redeem the Certificates, it shall, no
later than 30 days prior to the Distribution Date selected for redemption (the
"Redemption Date"), deliver written notice to the Trustee and the Securities
Administrator and either (a) deposit in the Distribution Account the Redemption
Price therefore or (b) state in such notice that the Redemption Price shall be
deposited in the Distribution Account not later than 10:00 a.m., New York City
time on the applicable Redemption Date. In connection with such redemption, if
the Holder of the Class LT-R Certificate elects to liquidate the assets of the
Trust Fund, such Holder shall cause the Trustee to cause each REMIC to adopt a
plan of complete liquidation for federal income tax purposes by complying with
the provisions of Section 7.02.

                                       96



         (c)      On any Distribution Date occurring on or after the Initial
Optional Purchase Date, the Depositor has the option to cause the Trust Fund to
adopt a plan of complete liquidation pursuant to Sections 7.02 and 7.03 hereof
to sell all of its property. If the Depositor elects to exercise such option, it
shall no later than 30 days prior to the Distribution Date selected for purchase
of the assets of the Trust Fund (the "Purchase Date") deliver written notice to
the Trustee and the Securities Administrator and either (a) deposit in the
Distribution Account the Redemption Price or (b) state in such notice that the
Redemption Price shall be deposited in the Distribution Account not later than
10:00 a.m., New York City time, on the applicable Purchase Date. Upon exercise
of such option, the property of the Trust Fund shall be sold to the Depositor at
a price equal to the Redemption Price.

         (d)      The Depositor, the Master Servicer, each Servicer, the
Securities Administrator and each Custodian shall be reimbursed from the
Redemption Price for any Advances, Servicer Advances, accrued and unpaid
Servicing Fees and Master Servicing Fees or other amounts with respect to the
related Mortgage Loans that are reimbursable to such parties under this
Agreement, the related Servicing Agreement or the Custody Agreements.

         Section 7.02 Procedure Upon Redemption Termination of Trust Fund.

         (a)      Notice of any redemption termination pursuant to the
provisions of Section 7.01, specifying the Distribution Date upon which the
final distribution shall be made or the Redemption Date of the Certificates,
shall be given promptly by the Trustee by first class mail to Certificateholders
mailed in the case of a redemption of the Certificate, no less than the first
day of the month in which the Distribution Date selected for redemption of the
Certificates occurs or upon (x) the sale of all of the property of the Trust
Fund by the Trustee or in the case of a sale of assets of the Trust Fund, or (y)
upon the final payment or other liquidation of the last Mortgage Loan or REO
Property in the Trust Fund. Such notice shall specify (A) the Redemption Date,
Distribution Date upon which final distribution on the Certificates of all
amounts required to be distributed to Certificateholders pursuant to Section
5.02 will be made upon presentation and surrender of the Certificates at the
Certificate Registrar's Corporate Trust Office, and (B) that the Record Date
otherwise applicable to such Distribution Date is not applicable, distribution
being made only upon presentation and surrender of the Certificates at the
office or agency of the Trustee therein specified. The Trustee shall give such
notice to the Securities Administrator, the Master Servicer and the Certificate
Registrar at the time such notice is given to Holders of the Certificates. Upon
any such termination, the duties of the Certificate Registrar with respect to
the Certificates shall terminate and the Trustee shall terminate or request the
Master Servicer to terminate, the Distribution Account and any other account or
fund maintained with respect to the Certificates, subject to the Trustee's
obligation hereunder to hold all amounts payable to Certificateholders in trust
without interest pending such payment.

         (b)      In the event that all of the Holders do not surrender their
Certificates for cancellation within three months after the time specified in
the above-mentioned written notice, the Trustee shall give a second written
notice to the remaining Certificateholders to surrender their Certificates for
cancellation and receive the final distribution with respect thereto. If within
one year after the second notice any Certificates shall not have been

                                       97



surrendered for cancellation, the Trustee may take appropriate steps to contact
the remaining Certificateholders concerning surrender of such Certificates, and
the cost thereof shall be paid out of the amounts distributable to such Holders.
If within two years after the second notice any Certificates shall not have been
surrendered for cancellation, the Trustee shall, subject to applicable state law
relating to escheatment, hold all amounts distributable to such Holders for the
benefit of such Holders. No interest shall accrue on any amount held by the
Trustee and not distributed to a Certificateholder due to such
Certificateholder's failure to surrender its Certificate(s) for payment of the
final distribution thereon in accordance with this Section.

         (c)      Any reasonable expenses incurred by the Trustee in connection
with any redemption or termination or liquidation of the Trust Fund shall be
reimbursed from proceeds received from the liquidation of the Trust Fund.

         Section 7.03 Additional Trust Fund Termination Requirements.

         (a)      Any termination of the Trust Fund shall be effected in
accordance with the following additional requirements, unless the Trustee seeks
(at the request of the party exercising the option to purchase all of the
Mortgage Loans pursuant to Section 7.01(c)), and subsequently receives, an
Opinion of Counsel (at the expense of such requesting party), addressed to the
Trustee to the effect that the failure of the Trust Fund to comply with the
requirements of this Section 7.03 will not result in an Adverse REMIC Event:

                  (i)      Within 89 days prior to the time of the making of the
         final payment on the Certificates, upon notification by the Depositor
         that it intends to exercise its option to cause the termination of the
         Trust Fund, the Trustee shall adopt a plan of complete liquidation of
         the Trust Fund on behalf of each REMIC, meeting the requirements of a
         qualified liquidation under the REMIC Provisions;

                  (ii)     Any sale of the assets of the Trust Fund pursuant to
         Section 7.02 shall be a sale for cash and shall occur at or after the
         time of adoption of such a plan of complete liquidation and prior to
         the time of making of the final payment on the Certificates;

                  (iii)    On the date specified for final payment of the
         Certificates, the Securities Administrator shall make final
         distributions of principal and interest on the Certificates in
         accordance with Section 5.02 and, after payment of, or provision for
         any outstanding expenses, distribute or credit, or cause to be
         distributed or credited, to the Holders of the Residual Certificates
         all cash on hand after such final payment (other than cash retained to
         meet claims), and the Trust Fund (and each REMIC) shall terminate at
         that time; and

                  (iv)     In no event may the final payment on the Certificates
         or the final distribution or credit to the Holders of the Residual
         Certificates be made after the 89th day from the date on which the plan
         of complete liquidation is adopted.

         (b)      By its acceptance of a Residual Certificate, each Holder
thereof hereby agrees to accept the plan of complete liquidation adopted by the
Trustee under this Section and to take such other action in connection therewith
as may be reasonably requested by the Securities Administrator or any Servicer.

                                       98



                                  ARTICLE VIII

                          RIGHTS OF CERTIFICATEHOLDERS

         Section 8.01 Limitation on Rights of Holders.

         (a)      The death or incapacity of any Certificateholder shall not
operate to terminate this Agreement or this Trust Fund, nor entitle such
Certificateholder's legal representatives or heirs to claim an accounting or
take any action or proceeding in any court for a partition or winding up of this
Trust Fund, nor otherwise affect the rights, obligations and liabilities of the
parties hereto or any of them. Except as otherwise expressly provided herein, no
Certificateholder, solely by virtue of its status as a Certificateholder, shall
have any right to vote or in any manner otherwise control the Master Servicer or
the operation and management of the Trust Fund, or the obligations of the
parties hereto, nor shall anything herein set forth, or contained in the terms
of the Certificates, be construed so as to constitute the Certificateholders
from time to time as partners or members of an association, nor shall any
Certificateholder be under any liability to any third person by reason of any
action taken by the parties to this Agreement pursuant to any provision hereof.

         (b)      No Certificateholder, solely by virtue of its status as
Certificateholder, shall have any right by virtue or by availing of any
provision of this Agreement to institute any suit, action or proceeding in
equity or at law upon or under or with respect to this Agreement, unless such
Holder previously shall have given to the Trustee a written notice of an Event
of Default and of the continuance thereof, as hereinbefore provided, and unless
also the Holders of Certificates evidencing not less than 25% of the Class
Principal Amount or Class Notional Amount (or Percentage Interest) of
Certificates of each Class affected thereby shall have made written request upon
the Trustee to institute such action, suit or proceeding in its own name as
Trustee hereunder and shall have offered to the Trustee such reasonable
indemnity as it may require against the cost, expenses and liabilities to be
incurred therein or thereby, and the Trustee, for sixty days after its receipt
of such notice, request and offer of indemnity, shall have neglected or refused
to institute any such action, suit or proceeding and no direction inconsistent
with such written request has been given such Trustee during such sixty-day
period by such Certificateholders; it being understood and intended, and being
expressly covenanted by each Certificateholder with every other
Certificateholder, the Securities Administrator and the Trustee, that no one or
more Holders of Certificates shall have any right in any manner whatever by
virtue or by availing of any provision of this Agreement to affect, disturb or
prejudice the rights of the Holders of any other of such Certificates, or to
obtain or seek to obtain priority over or preference to any other such Holder,
or to enforce any right under this Agreement, except in the manner herein
provided and for the benefit of all Certificateholders. For the protection and
enforcement of the provisions of this Section, each and every Certificateholder
and the Trustee shall be entitled to such relief as can be given either at law
or in equity.

         Section 8.02 Access to List of Holders.

         (a)      If the Trustee is not acting as Certificate Registrar, the
Certificate Registrar will furnish or cause to be furnished to the Trustee,
within fifteen days after receipt by the Certificate Registrar of a request by
the Trustee in writing, a list, in such form as the Trustee may

                                       99



reasonably require, of the names and addresses of the Certificateholders of each
Class as of the most recent Record Date.

         (b)      If three or more Holders or Certificate Owners (hereinafter
referred to as "Applicants") apply in writing to the Trustee, and such
application states that the Applicants desire to communicate with other Holders
with respect to their rights under this Agreement or under the Certificates and
is accompanied by a copy of the communication which such Applicants propose to
transmit, then the Trustee shall, within five Business Days after the receipt of
such application, afford such Applicants reasonable access during the normal
business hours of the Trustee to the most recent list of Certificateholders held
by the Trustee or shall, as an alternative, send, at the Applicants' expense,
the written communication proffered by the Applicants to all Certificateholders
at their addresses as they appear in the Certificate Register.

         (c)      Every Holder or Certificate Owner, if the Holder is a Clearing
Agency, by receiving and holding a Certificate, agrees with the Depositor, the
Master Servicer, the Securities Administrator, the Certificate Registrar and the
Trustee that neither the Depositor, the Master Servicer, the Securities
Administrator, the Certificate Registrar nor the Trustee shall be held
accountable by reason of the disclosure of any such information as to the names
and addresses of the Certificateholders hereunder, regardless of the source from
which such information was derived.

         Section 8.03 Acts of Holders of Certificates.

         (a)      Any request, demand, authorization, direction, notice,
consent, waiver or other action provided by this Agreement to be given or taken
by Holders or Certificate Owners, if the Holder is a Clearing Agency, may be
embodied in and evidenced by one or more instruments of substantially similar
tenor signed by such Holders in person or by agent duly appointed in writing;
and, except as herein otherwise expressly provided, such action shall become
effective when such instrument or instruments are delivered to the Trustee and
the Securities Administrator and, where expressly required herein, to the Master
Servicer. Such instrument or instruments (as the action embodies therein and
evidenced thereby) are herein sometimes referred to as an "Act" of the Holders
signing such instrument or instruments. Proof of execution of any such
instrument or of a writing appointing any such agents shall be sufficient for
any purpose of this Agreement and conclusive in favor of the Trustee, the
Securities Administrator and the Master Servicer, if made in the manner provided
in this Section. Each of the Trustee, the Securities Administrator and the
Master Servicer shall promptly notify the others of receipt of any such
instrument by it, and shall promptly forward a copy of such instrument to the
others.

         (b)      The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by the certificate of any notary public or other officer authorized
by law to take acknowledgments or deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Whenever
such execution is by an officer of a corporation or a member of a partnership on
behalf of such corporation or partnership, such certificate or affidavit shall
also constitute sufficient proof of his authority. The fact and date of the
execution of any such instrument or writing, or the authority of the individual
executing the same, may also be proved in any other manner which the Trustee
deems sufficient.

                                       100



         (c)      The ownership of Certificates (whether or not such
Certificates shall be overdue and notwithstanding any notation of ownership or
other writing thereon made by anyone other than the Trustee) shall be proved by
the Certificate Register, and neither the Trustee, the Securities Administrator,
the Master Servicer, nor the Depositor shall be affected by any notice to the
contrary.

         (d)      Any request, demand, authorization, direction, notice,
consent, waiver or other action by the Holder of any Certificate shall bind
every future Holder of the same Certificate and the Holder of every Certificate
issued upon the registration of transfer thereof or in exchange therefor or in
lieu thereof, in respect of anything done, omitted or suffered to be done by the
Trustee or the Master Servicer in reliance thereon, whether or not notation of
such action is made upon such Certificate.

                                   ARTICLE IX

                 ADMINISTRATION AND SERVICING OF MORTGAGE LOANS
                             BY THE MASTER SERVICER

         Section 9.01 Duties of the Master Servicer; Enforcement of Servicer's
                      and Master Servicer's Obligations.

         (a)      The Master Servicer, on behalf of the Trustee, the Depositor
and the Certificateholders shall monitor the performance of the Servicers under
the Servicing Agreements, and shall use its reasonable good faith efforts to
cause the Servicers duly and punctually to perform all of their duties and
obligations thereunder. Upon the occurrence of a default of which an Authorized
Officer of the Master Servicer has actual knowledge under a Servicing Agreement,
the Master Servicer shall promptly notify the Trustee thereof, and shall specify
in such notice the action, if any, the Master Servicer is taking in respect of
such default. So long as any such default shall be continuing, the Master
Servicer may, and shall if it determines such action to be in the best interests
of Certificateholders, (i) terminate all of the rights and powers of such
Servicer pursuant to the applicable provisions of the Servicing Agreement; (ii)
exercise any rights it may have to enforce the Servicing Agreement against such
Servicer; and/or (iii) waive any such default under the Servicing Agreement or
take any other action with respect to such default as is permitted thereunder.
Notwithstanding any provision of this Agreement or any Servicing Agreement to
the contrary, the Master Servicer shall have no duty or obligation to supervise,
monitor or oversee the activities of, or to enforce the obligations of, (i) the
Servicer under its Servicing Agreement with respect to any Additional Collateral
or any Limited Purpose Surety Bond relating thereto, including, without
limitation, the collection of any amounts owing to the Trust Fund in respect
thereof (unless and until the Master Servicer shall have assumed the obligations
of such Servicer as successor servicer under the related Servicing Agreement
pursuant to this Section 9.01, in which case, as successor servicer, it shall be
bound to serve and administer the Additional Collateral and any related Limited
Purpose Surety Bond in accordance with the provisions of such Servicing
Agreement) or (ii) the Servicer under its Servicing Agreement with respect to
the servicing or administration of defaulted or delinquent Mortgage Loans and
the management and disposition of any REO Properties or for any actions of the
Trustee in connection therewith.

                                       101



         (b)      Upon any termination by the Master Servicer of a Servicer's
rights and powers pursuant to its Servicing Agreement, the rights and powers of
the Servicer with respect to the Mortgage Loans shall vest in the Master
Servicer and the Master Servicer shall be the successor in all respects to such
Servicer in its capacity as Servicer with respect to such Mortgage Loans under
the related Servicing Agreement, unless or until the Master Servicer shall have
appointed, with the consent of the Trustee and the Rating Agencies, such consent
not to be unreasonably withheld, and in accordance with the applicable
provisions of the Servicing Agreement, a new Fannie Mae- or FHLMC-approved
Person to serve as successor to the Servicer; provided, however, that it is
understood and agreed by the parties hereto that there will be a period of
transition (not to exceed 90 days) before the actual servicing functions can be
fully transferred to a successor servicer (including the Master Servicer). With
such consent, the Master Servicer may elect to continue to serve as successor
servicer under the Servicing Agreement. Upon appointment of a successor
servicer, as authorized under this Section 9.01(b), unless the successor
servicer shall have assumed the obligation of the terminated Servicer under such
Servicing Agreement, the Trustee and such successor servicer shall enter into a
servicing agreement in a form substantially similar to the affected Servicing
Agreement. In connection with any such appointment, the Master Servicer may make
such arrangements for the compensation of such successor as it and such
successor shall agree, but in no event shall such compensation of any successor
servicer (including the Master Servicer) be in excess of that payable to the
Servicer under the affected Servicing Agreement.

         The Master Servicer shall pay the costs of such enforcement (including
the termination of any Servicer, the appointment of a successor servicer or the
transfer and assumption of the servicing by the Master Servicer) at its own
expense and shall be reimbursed therefor initially (i) by the terminated
Servicer, (ii) from a general recovery resulting from such enforcement only to
the extent, if any, that such recovery exceeds all amounts due in respect of the
related Mortgage Loans, (iii) from a specific recovery of costs, expenses or
attorney's fees against the party against whom such enforcement is directed, or
(iv) to the extent that such amounts described in (i)-(iii) above are
insufficient to reimburse the Master Servicer for such costs of enforcement,
from the Trust Fund, as provided in Section 9.04.

         If the Master Servicer assumes the servicing with respect to any of the
Mortgage Loans, it will not assume liability for the representations and
warranties of any Servicer it replaces or for the errors or omissions of such
Servicer.

         (c)      Upon any termination of a Servicer's rights and powers
pursuant to its Servicing Agreement, the Master Servicer shall promptly notify
the Trustee and the Rating Agencies, specifying in such notice that the Master
Servicer or any successor servicer, as the case may be, has succeeded the
Servicer under the Servicing Agreement, which notice shall also specify the name
and address of any such successor servicer.

         (d)      Neither the Depositor nor the Trustee shall consent to the
assignment by any Servicer of such Servicer's rights and obligations under the
Servicing Agreement without the prior written consent of the Master Servicer,
which consent shall not be unreasonably withheld.

                                       102



         Section 9.02 Assumption of Master Servicing by Trustee.

         (a)      In the event the Master Servicer shall for any reason no
longer be the Master Servicer (including by reason of any Event of Default under
this Agreement), the Trustee shall thereupon assume all of the rights and
obligations of such Master Servicer hereunder and under each Servicing Agreement
entered into with respect to the Mortgage Loans or shall appoint a Fannie-Mae or
FHLMC-approved server as successor with servicer acceptable to the Depositor and
the Rating Agencies. The Trustee, its designee or any successor master servicer
appointed by the Trustee shall be deemed to have assumed all of the Master
Servicer's interest herein and therein to the same extent as if such Servicing
Agreement had been assigned to the assuming party, except that the Master
Servicer shall not thereby be relieved of any liability or obligations of the
Master Servicer under such Servicing Agreement accruing prior to its replacement
as Master Servicer, and shall be liable to the Trustee, and hereby agrees to
indemnify and hold harmless the Trustee from and against all costs, damages,
expenses and liabilities (including reasonable attorneys' fees) incurred by the
Trustee as a result of such liability or obligations of the Master Servicer and
in connection with the Trustee's assumption (but not its performance, except to
the extent that costs or liability of the Trustee are created or increased as a
result of negligent or wrongful acts or omissions of the Master Servicer prior
to its replacement as Master Servicer) of the Master Servicer's obligations,
duties or responsibilities thereunder.

         (b)      The Master Servicer that has been terminated shall, upon
request of the Trustee but at the expense of such Master Servicer, deliver to
the assuming party all documents and records relating to each Servicing
Agreement and the related Mortgage Loans and an accounting of amounts collected
and held by it and otherwise use its best efforts to effect the orderly and
efficient transfer of each Servicing Agreement to the assuming party.

         Section 9.03 Representations and Warranties of the Master Servicer.

         (a)      The Master Servicer hereby represents and warrants to the
Depositor, the Securities Administrator and the Trustee, for the benefit of the
Certificateholders, as of the Closing Date that:

                  (i)      it is validly existing and in good standing under the
         laws of the United States of America as a national banking association,
         and as Master Servicer has full power and authority to transact any and
         all business contemplated by this Agreement and to execute, deliver and
         comply with its obligations under the terms of this Agreement, the
         execution, delivery and performance of which have been duly authorized
         by all necessary corporate action on the part of the Master Servicer;

                  (ii)     the execution and delivery of this Agreement by the
         Master Servicer and its performance and compliance with the terms of
         this Agreement will not (A) violate the Master Servicer's charter or
         bylaws, (B) violate any law or regulation or any administrative decree
         or order to which it is subject or (C) constitute a default (or an
         event which, with notice or lapse of time, or both, would constitute a
         default) under, or result in the breach of, any material contract,
         agreement or other instrument to which the Master Servicer is a party
         or by which it is bound or to which any of its assets are subject,
         which violation, default or breach would materially and adversely
         affect the Master Servicer's ability to perform its obligations under
         this Agreement;

                                       103



                  (iii)    this Agreement constitutes, assuming due
         authorization, execution and delivery hereof by the other respective
         parties hereto, a legal, valid and binding obligation of the Master
         Servicer, enforceable against it in accordance with the terms hereof,
         except as such enforcement may be limited by bankruptcy, insolvency,
         reorganization, moratorium and other laws affecting the enforcement of
         creditors' rights in general, and by general equity principles
         (regardless of whether such enforcement is considered in a proceeding
         in equity or at law);

                  (iv)     the Master Servicer is not in default with respect to
         any order or decree of any court or any order or regulation of any
         federal, state, municipal or governmental agency to the extent that any
         such default would materially and adversely affect its performance
         hereunder;

                  (v)      the Master Servicer is not a party to or bound by any
         agreement or instrument or subject to any charter provision, bylaw or
         any other corporate restriction or any judgment, order, writ,
         injunction, decree, law or regulation that may materially and adversely
         affect its ability as Master Servicer to perform its obligations under
         this Agreement or that requires the consent of any third person to the
         execution of this Agreement or the performance by the Master Servicer
         of its obligations under this Agreement;

                  (vi)     no litigation is pending or, to the best of the
         Master Servicer's knowledge, threatened against the Master Servicer
         which would prohibit its entering into this Agreement or performing its
         obligations under this Agreement;

                  (vii)    the Master Servicer, or an affiliate thereof the
         primary business of which is the servicing of conventional residential
         mortgage loans, is a Fannie Mae- or FHLMC-approved seller/servicer;

                  (viii)   no consent, approval, authorization or order of any
         court or governmental agency or body is required for the execution,
         delivery and performance by the Master Servicer of or compliance by the
         Master Servicer with this Agreement or the consummation of the
         transactions contemplated by this Agreement, except for such consents,
         approvals, authorizations and orders (if any) as have been obtained;
         and

                  (ix)     the consummation of the transactions contemplated by
         this Agreement are in the ordinary course of business of the Master
         Servicer;

         (b)      It is understood and agreed that the representations and
warranties set forth in this Section shall survive the execution and delivery of
this Agreement. The Master Servicer shall indemnify the Depositor, the
Securities Administrator and the Trustee and hold them harmless against any
loss, damages, penalties, fines, forfeitures, legal fees and related costs,
judgments, and other costs and expenses resulting from any claim, demand,
defense or assertion based on or grounded upon, or resulting from, a material
breach of the Master Servicer's representations and warranties contained in
Section 9.03(a). It is understood and agreed that the enforcement of the
obligation of the Master Servicer set forth in this Section to indemnify the
Depositor, the Securities Administrator and the Trustee as provided in this
Section constitutes the sole remedy (other than as set forth in Section 6.14) of
the Depositor, the Securities Administrator and the

                                       104



Trustee, respecting a breach of the foregoing representations and warranties.
Such indemnification shall survive any termination of the Master Servicer as
Master Servicer hereunder, and any termination of this Agreement.

         Any cause of action against the Master Servicer relating to or arising
out of the breach of any representations and warranties made in this Section
shall accrue upon discovery of such breach by either the Depositor, the Master
Servicer or the Trustee or notice thereof by any one of such parties to the
other parties.

         Section 9.04 Compensation to the Master Servicer.

         The Master Servicer shall be entitled to be paid by the Trust Fund, and
either retain or withdraw from the Distribution Account, (i) its Master
Servicing Fee with respect to each Distribution Date, (ii) amounts necessary to
reimburse itself for any previously unreimbursed Advances, Servicer Advances and
Nonrecoverable Advances in accordance with the definition of "Available
Distribution Amount" and (iii) amounts representing assumption fees, late
payment charges or other ancillary income not included in the definition of
"Available Distribution Amount" and which are not required to be remitted by the
Servicers to the Securities Administrator or deposited by the Securities
Administrator into the Distribution Account. The Master Servicer shall be
required to pay all expenses incurred by it in connection with its activities
hereunder and shall not be entitled to reimbursement therefor except as provided
in this Agreement.

         In addition, Depositor agrees, except as otherwise expressly provided
herein, to reimburse the Master Servicer, upon its request, for all reasonable
expenses, disbursements and advances incurred or made by the Master Servicer in
connection with the performance of its duties hereunder (including the
reasonable compensation and the expenses and disbursements of its agents and
counsel), to the extent not otherwise reimbursed pursuant to this Agreement,
except any such expense, disbursement or advance as may be attributable to its
willful misfeasance, bad faith or negligence.

         Section 9.05 Merger or Consolidation.

         Any Person into which the Master Servicer may be merged or
consolidated, or any Person resulting from any merger, conversion, other change
in form or consolidation to which the Master Servicer shall be a party, or any
Person succeeding to the business of the Master Servicer, shall be the successor
to the Master Servicer hereunder, without the execution or filing of any paper
or any further act on the part of any of the parties hereto, anything herein to
the contrary notwithstanding; provided, however, that the successor or resulting
Person to the Master Servicer shall be a Person that shall be qualified and
approved to service mortgage loans for Fannie Mae or FHLMC and shall have a net
worth of not less than $15,000,000.

         Section 9.06 Resignation of Master Servicer.

         Except as otherwise provided in Sections 9.05 and 9.07 hereof, the
Master Servicer shall not resign from the obligations and duties hereby imposed
on it unless the Master Servicer's duties hereunder 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 and cannot be cured. Any such

                                       105



determination permitting the resignation of the Master Servicer shall be
evidenced by an Opinion of Counsel that shall be Independent to such effect
delivered to the Trustee. No such resignation shall become effective until the
Trustee shall have assumed, or a successor master servicer shall have been
appointed by the Trustee and until such successor shall have assumed, the Master
Servicer's responsibilities and obligations under this Agreement. Notice of such
resignation shall be given promptly by the Master Servicer and the Depositor to
the Trustee.

         If, at any time, the Master Servicer resigns under this Section 9.06,
or transfers or assigns its rights and obligations under Section 9.07, or is
removed as Master Servicer pursuant to Section 6.14, then at such time as Wells
Fargo Bank Minnesota, National Association also shall resign (and shall be
entitled to resign) as Securities Administrator, Paying Agent, Authenticating
Agent and Certificate Registrar under this Agreement. In such event, the
obligations of each such party shall be assumed by the Trustee or such successor
master servicer appointed by the Trustee (subject to the provisions of Section
9.02(c)).

         Section 9.07 Assignment or Delegation of Duties by the Master Servicer.

         Except as expressly provided herein, the Master Servicer shall not
assign or transfer any of its rights, benefits or privileges hereunder to any
other Person, or delegate to or subcontract with, or authorize or appoint any
other Person to perform any of the duties, covenants or obligations to be
performed by the Master Servicer hereunder; provided, however, that the Master
Servicer shall have the right with the prior written consent of the Trustee and
the Depositor (which consent shall not be unreasonably withheld), and upon
delivery to the Trustee and the Depositor of a letter from each Rating Agency to
the effect that such action shall not result in a downgrading of the
Certificates, to delegate or assign to or subcontract with or authorize or
appoint any qualified Person to perform and carry out any duties, covenants or
obligations to be performed and carried out by the Master Servicer hereunder.
Notice of such permitted assignment shall be given promptly by the Master
Servicer to the Depositor and the Trustee. If, pursuant to any provision hereof,
the duties of the Master Servicer are transferred to a successor master
servicer, the entire amount of the Master Servicing Fees and other compensation
payable to the Master Servicer pursuant hereto shall thereafter be payable to
such successor master servicer. Such successor Master Servicer shall also pay
the fees of the Trustee and the Securities Administrator, as provided herein.

         Section 9.08 Limitation on Liability of the Master Servicer and Others.

         Neither the Master Servicer nor any of the directors, officers,
employees or agents of the Master Servicer shall be under any liability to the
Trustee or the Certificateholders for any action taken or for refraining from
the taking of any action in good faith pursuant to this Agreement, or for errors
in judgment; provided, however, that this provision shall not protect the Master
Servicer or any such person against any liability that would otherwise be
imposed by reason of willful misfeasance, bad faith or negligence in its
performance of its duties or by reason of reckless disregard for its obligations
and duties under this Agreement. The Master Servicer and any director, officer,
employee or agent of the Master Servicer may rely in good faith on any document
of any kind prima facie properly executed and submitted by any Person respecting
any matters arising hereunder. The Master Servicer shall be under no obligation
to appear in, prosecute or defend any legal action that is not incidental to its
duties to master service the Mortgage Loans in accordance with this Agreement
and that in its opinion may involve it in any

                                       106



expenses or liability; provided, however, that the Master Servicer may in its
sole discretion undertake any such action that it may deem necessary or
desirable in respect to this Agreement and the rights and duties of the parties
hereto and the interests of the Certificateholders hereunder. In such event, the
legal expenses and costs of such action and any liability resulting therefrom
shall be expenses, costs and liabilities of the Trust Fund and the Master
Servicer shall be entitled to be reimbursed therefor out of the Distribution
Account.

         The Master Servicer shall not be liable for any acts or omissions of
any Servicer except to the extent that damages or expenses are incurred as a
result of such act or omissions and such damages and expenses would not have
been incurred but for the negligence, willful misfeasance, bad faith or
recklessness of the Master Servicer in supervising, monitoring and overseeing
the obligations of the Servicers in this Agreement.

         Section 9.09 Indemnification; Third-Party Claims.

         The Master Servicer agrees to indemnify the Depositor, the Securities
Administrator and the Trustee, and hold them harmless against any and all
claims, losses, penalties, fines, forfeitures, legal fees and related costs,
judgments, and any other costs, liability, fees and expenses that the Depositor,
the Securities Administrator or the Trustee may sustain as a result of the
Master Servicer's willful misfeasance, bad faith or negligence in the
performance of its duties hereunder or by reason of its reckless disregard for
its obligations and duties under this Agreement. The Depositor, the Securities
Administrator and the Trustee shall immediately notify the Master Servicer if a
claim is made by a third party with respect to this Agreement or the Mortgage
Loans entitling the Depositor, the Securities Administrator or the Trustee to
indemnification under this Section 9.09, whereupon the Master Servicer shall
assume the defense of any such claim and pay all expenses in connection
therewith, including counsel fees, and promptly pay, discharge and satisfy any
judgment or decree which may be entered against it or them in respect of such
claim.

                                    ARTICLE X

                              REMIC ADMINISTRATION

         Section 10.01 REMIC Administration.

         (a)      REMIC elections as set forth in the Preliminary Statement
shall be made on Forms 1066 or other appropriate federal tax or information
return for the taxable year ending on the last day of the calendar year in which
the Certificates are issued. The regular interests and residual interest in each
REMIC shall be as designated in the Preliminary Statement.

         (b)      The Closing Date is hereby designated as the "Startup Day" of
each REMIC within the meaning of section 86OG(a)(9) of the Code. The latest
possible maturity date for purposes of Treasury Regulation 1.86OG-1(a)(4) will
be the Latest Possible Maturity Date.

         (c)      The Securities Administrator shall represent the Trust Fund in
any administrative or judicial proceeding relating to an examination or audit by
any governmental taxing authority with respect thereto. The Securities
Administrator shall pay any and all tax related expenses (not including taxes)
of each REMIC, including but not limited to any professional fees or expenses

                                       107



related to audits or any administrative or judicial proceedings with respect to
such REMIC that involve the Internal Revenue Service or state tax authorities,
but only to the extent that (i) such expenses are ordinary or routine expenses,
including expenses of a routine audit but not expenses of litigation (except as
described in (ii)); or (ii) such expenses or liabilities (including taxes and
penalties) are attributable to the negligence or willful misconduct of the
Securities Administrator in fulfilling its duties hereunder (including its
duties as tax return preparer). The Securities Administrator shall be entitled
to reimbursement of expenses to the extent provided in clause (i) above from the
Securities Administration Account, provided, however, the Securities
Administrator shall not be entitled to reimbursement for expenses incurred in
connection with the preparation of tax returns and other reports as required by
Section 6.20 and this Section.

         (d)      The Securities Administrator shall prepare, and the Trustee
shall sign and file, as instructed by the Securities Administrator, all of each
REMIC's federal and appropriate state tax and information returns as such
REMIC's direct representative. The expenses of preparing and filing such returns
shall be borne by the Securities Administrator. In preparing such returns, the
Securities Administrator shall, with respect to each REMIC created hereunder
other than the Upper-Tier REMIC (each such REMIC, a "Non-Upper-Tier REMIC"): (i)
treat the accrual period for interests in such Non-Upper-Tier REMIC as the
calendar month; (ii) account for distributions made from such Non-Upper-Tier
REMIC as made on the first day of each succeeding calendar month; (iii) account
for income under the all-OID method at the Net WAC; (iv) use the aggregation
method provided in Treasury Regulation section 1.1275-2(c); and (v) account for
income and expenses related to such Non-Upper-Tier REMIC in the manner resulting
in the lowest amount of excess inclusion income possible accruing to the Holder
of the residual interest in such Non-Upper-Tier REMIC.

         (e)      The Securities Administrator or its designee shall perform on
behalf of each REMIC all reporting and other tax compliance duties that are the
responsibility of such REMIC under the Code, the REMIC Provisions, or other
compliance guidance issued by the Internal Revenue Service or any state or local
taxing authority. Among its other duties, if required by the Code, the REMIC
Provisions, or other such guidance, the Securities Administrator shall provide,
upon receipt of additional reasonable compensation, (i) to the Treasury or other
governmental authority such information as is necessary for the application of
any tax relating to the transfer of a Residual Certificate to any disqualified
person or organization pursuant to Treasury Regulation 1.860E-2(a)(5) and any
person designated in Section 860E(e)(3) of the Code and (ii) to the Trustee such
information as is necessary for the Trustee to provide to the Certificateholders
such information or reports as are required by the Code or REMIC Provisions.

         (f)      The Trustee, the Securities Administrator, the Master Servicer
and the Holders of Certificates shall take any action or cause any REMIC to take
any action necessary to create or maintain the status of any REMIC as a REMIC
under the REMIC Provisions and shall assist each other as necessary to create or
maintain such status. Neither the Trustee, the Securities Administrator, the
Master Servicer nor the Holder of any Residual Certificate shall knowingly take
any action, cause any REMIC to take any action or fail to take (or fail to cause
to be taken) any action that, under the REMIC Provisions, if taken or not taken,
as the case may be, could result in an Adverse REMIC Event unless the Trustee,
the Securities Administrator and the Master Servicer have received an Opinion of
Counsel (at the expense of the party seeking to take such action) to the effect
that the contemplated action will not endanger such status or result in

                                       108



the imposition of such a tax. In addition, prior to taking any action with
respect to any REMIC or the assets therein, or causing any REMIC to take any
action, which is not expressly permitted under the terms of this Agreement, any
Holder of a Residual Certificate will consult with the Trustee, the Securities
Administrator, the Master Servicer or their respective designees, in writing,
with respect to whether such action could cause an Adverse REMIC Event to occur
with respect to any REMIC, and no such Person shall take any such action or
cause any REMIC to take any such action as to which the Trustee, the Securities
Administrator or the Master Servicer has advised it in writing that an Adverse
REMIC Event could occur; provided, however, that if no Adverse REMIC Event would
occur but such action could result in the imposition of additional taxes on the
Residual Certificateholders, no such Person shall take any such action, or cause
any REMIC to take any such action without the written consent of the Residual
Certificateholders.

         (g)      Each Holder of a Residual Certificate shall pay when due any
and all taxes imposed on the related REMIC by federal or state governmental
authorities. To the extent that such taxes are not paid by a Residual
Certificateholder, the Trustee or the Paying Agent shall pay any remaining REMIC
taxes out of current or future amounts otherwise distributable to the Holder of
the Residual Certificate in any such REMIC or, if no such amounts are available,
out of other amounts held in the Collection Account, and shall reduce amounts
otherwise payable to holders of regular interests in any such REMIC, as the case
may be.

         (h)      The Securities Administrator shall, for federal income tax
purposes, maintain books and records with respect to each REMIC on a calendar
year and on an accrual basis.

         (i)      No additional contributions of assets shall be made to any

REMIC, except as expressly provided in this Agreement.

         (j)      Neither the Securities Administrator nor the Master Servicer
shall enter into any arrangement by which any REMIC will receive a fee or other
compensation for services.

         (k)      The Trustee and the Securities Administrator shall treat the
Reserve Fund as an outside reserve fund within the meaning of Treasury
Regulation Section 1.860G-2(h) that is owned by the holders of the Interest-Only
Certificates and that is not an asset of any REMIC. The Trustee and the
Securities Administrator shall treat the rights of the Holders of the LIBOR
Certificates to receive distributions from the Reserve Fund to cover Net WAC
Shortfalls as payments under a cap contract written by the Holders of the Class
X-1, Class X-2 and Class X-B Certificates in favor of the Holders of the LIBOR
Certificates. The Trustee and the Securities Administrator shall treat the
rights of the Holders of the Class X-1 Certificates to receive distributions
from the Reserve Fund to cover any related Required Reserve Fund Deposits as
payments under a cap contract written by the Holders of the Class X-2
Certificates in favor of the Holders of the Class X-1 Certificates. Thus, each
Class A-1, Class A-2 and Class B-1 Certificates shall be treated as representing
not only ownership of regular interests in a REMIC, but also ownership of an
interest in an interest rate cap contract. For purposes of determining the issue
prices of the Certificates, the interest rate cap contracts shall be assumed to
have a zero value unless and until required otherwise by an applicable taxing
authority.

         (l)      The Class LT-R Holder shall act as "tax matters person" with
respect to the Lower-Tier REMIC and shall act as agent for the Class A-R
Certificateholder as "tax matters

                                       109



person" with respect to the Middle-Tier REMIC and the Upper-Tier REMIC and the
Securities Administrator shall act as agent for the Class LT-R Holder in such
roles, unless and until another party is so designated by the Class LT-R Holder.

         Section 10.02 Prohibited Transactions and Activities.

         Neither the Depositor, the Master Servicer nor the Trustee shall sell,
dispose of, or substitute for any of the Mortgage Loans, except in a disposition
pursuant to (i) the foreclosure of a Mortgage Loan, (ii) the bankruptcy of the
Trust Fund, (iii) the termination of each REMIC pursuant to Article VII of this
Agreement, (iv) a substitution pursuant to Article II of this Agreement or (v) a
repurchase of Mortgage Loans pursuant to Article II of this Agreement, nor
acquire any assets for any REMIC, nor sell or dispose of any investments in the
Distribution Account for gain, nor accept any contributions to any REMIC after
the Closing Date, unless it has received an Opinion of Counsel (at the expense
of the party causing such sale, disposition, or substitution) that such
disposition, acquisition, substitution, or acceptance will not result in an
Adverse REMIC Event, (b) affect the distribution of interest or principal on the
Certificates or (c) result in the encumbrance of the assets transferred or
assigned to the Trust Fund (except pursuant to the provisions of this
Agreement).

         Section 10.03 Indemnification with Respect to Prohibited Transactions
                       or Loss of REMIC Status.

         Upon the occurrence of an Adverse REMIC Event due to the negligent
performance by the Securities Administrator of its duties and obligations set
forth herein, the Securities Administrator shall indemnify the
Certificateholders of the related Residual Certificate against any and all
losses, claims, damages, liabilities or expenses ("Losses") resulting from such
negligence; provided, however, that the Securities Administrator shall not be
liable for any such Losses attributable to the action or inaction of the
Depositor, the Trustee or the Holder of the Residual Certificate, nor for any
such Losses resulting from misinformation provided by any of the foregoing
parties on which the Securities Administrator has relied. Notwithstanding the
foregoing, however, in no event shall the Securities Administrator have any
liability (1) for any action or omission that is taken in accordance with and in
compliance with the express terms of, or which is expressly permitted by the
terms of, this Agreement or under any Servicing Agreement or under any
Acknowledgement, (2) for any Losses other than arising out of malfeasance,
willful misconduct or negligent performance by the Service Administrator of its
duties and obligations set forth herein, and (3) for any special or
consequential damages to Certificateholders of the related Residual Certificate
(in addition to payment of principal and interest on the Certificates).

         Section 10.04 REO Property.

         (a)      Notwithstanding any other provision of this Agreement, the
Master Servicer, acting on behalf of the Trustee hereunder, shall not, except to
the extent provided in the applicable Servicing Agreement, knowingly permit any
Servicer to, rent, lease, or otherwise earn income on behalf of any REMIC with
respect to any REO Property which might cause an Adverse REMIC Event unless the
applicable Servicer has provided to the Trustee an Opinion of Counsel concluding
that, under the REMIC Provisions, such action would not adversely affect

the status of any REMIC as a REMIC and any income generated for any REMIC by the
REO Property would not result in an Adverse REMIC Event.

         (b)      The Depositor shall cause the applicable Servicer (to the
extent provided in its Servicing Agreement) to make reasonable efforts to sell
any REO Property for its fair market value. In any event, however, the Depositor
shall, or shall cause the applicable Servicer (to the extent provided in its
Servicing Agreement) to, dispose of any REO Property within three years of its
acquisition by the Trust Fund unless the Depositor or the applicable Servicer
(on behalf of the Trust Fund) has received a grant of extension from the
Internal Revenue Service to the effect that, under the REMIC Provisions and any
relevant proposed legislation and under applicable state law, the REMIC may hold
REO Property for a longer period without causing an Adverse REMIC Event. If such
an extension has been received, then the Depositor, acting on behalf of the
Trustee hereunder, shall, or shall cause the applicable Servicer to, continue to
attempt to sell the REO Property for its fair market value for such period
longer than three years as such extension permits (the "Extended Period"). If
such an extension has not been received and the Depositor or the applicable
Servicer, acting on behalf of the Trust Fund hereunder, is unable to sell the
REO Property within 33 months after its acquisition by the Trust Fund or if such
an extension, has been received and the Depositor or the applicable Servicer is
unable to sell the REO Property within the period ending three months before the
close of the Extended Period, the Depositor shall cause the applicable Servicer,
before the end of the three year period or the Extended Period, as applicable,
to (i) purchase such REO Property at a price equal to the REO Property's fair
market value or (ii) auction the REO Property to the highest bidder (which may
be the applicable Servicer) in an auction reasonably designed to produce a fair
price prior to the expiration of the three-year period or the Extended Period,
as the case may be.

         Section 11.01 Binding Nature of Agreement; Assignment.

         This Agreement shall be binding upon and inure to the benefit of the
parties hereto and their respective successors and permitted assigns.

         Section 11.02 Entire Agreement.

         This Agreement contains the entire agreement and understanding among
the parties hereto with respect to the subject matter hereof, and supersedes all
prior and contemporaneous agreements, understandings, inducements and
conditions, express or implied, oral or written, of any nature whatsoever with
respect to the subject matter hereof. The express terms hereof control and
supersede any course of performance and/or usage of the trade inconsistent with
any of the terms hereof.

         Section 11.03 Amendment.

         (a)      This Agreement may be amended from time to time by the
Depositor, the Master Servicer, the Securities Administrator, and the Trustee,
without notice to or the consent of any of the Holders, (i) to cure any
ambiguity or mistake, (ii) to cause the provisions herein to conform

                                       111



to or be consistent with or in furtherance of the statements made with respect
to the Certificates, the Trust Fund or this Agreement in any Offering Document,
or to correct or supplement any provision herein which may be inconsistent with
any other provisions herein or with the provisions of any Servicing Agreement,
(iii) to make any other provisions with respect to matters or questions arising
under this Agreement or (iv) to add, delete, or amend any provisions to the
extent necessary or desirable to comply with any requirements imposed by the
Code and the REMIC Provisions. No such amendment effected pursuant to the
preceding sentence shall, as evidenced by an Opinion of Counsel, result in an
Adverse REMIC Event, nor shall such amendment effected pursuant to clause (iii)
of such sentence adversely affect in any material respect the interests of any
Holder. Prior to entering into any amendment without the consent of Holders
pursuant to this paragraph, the Trustee shall be provided with an Opinion of
Counsel (at the expense of the party requesting such amendment) to the effect
that such amendment is permitted under this Section. Any such amendment shall be
deemed not to adversely affect in any material respect any Holder, if the
Trustee receives written confirmation from each Rating Agency that such
amendment will not cause such Rating Agency to reduce the then current rating
assigned to the Certificates.

         (b)      This Agreement may also be amended from time to time by the
Depositor, the Master Servicer, the Securities Administrator and the Trustee,
with the consent of the Holders of not less than 66-2/3% of the Class Principal
Amount (or Percentage Interest) of each 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 this Agreement or of modifying in any
manner the rights of the Holders; provided, however, that no such amendment
shall be made unless the Trustee receives an Opinion of Counsel, at the expense
of the party requesting the change, that such change will not cause an Adverse
REMIC Event; and provided further, that no such amendment may (i) reduce in any
manner the amount of, or delay the timing of, payments received on Mortgage
Loans which are required to be distributed on any Certificate, without the
consent of the Holder of such Certificate or (ii) reduce the aforesaid
percentages of Class Principal Amount or Class Notional Amount (or Percentage
Interest) of Certificates of each Class, the Holders of which are required to
consent to any such amendment without the consent of the Holders of 100% of the
Class Principal Amount or Class Notional Amount (or Percentage Interest) of each
Class of Certificates affected thereby. For purposes of this paragraph,
references to "Holder" or "Holders" shall be deemed to include, in the case of
any Class of Book-Entry Certificates, the related Certificate Owners.

         (c)      Promptly after the execution of any such amendment, the
Trustee shall furnish written notification of the substance of such amendment to
each Holder, the Depositor and the Rating Agencies.

         (d)      It shall not be necessary for the consent of Holders under
this Section 11.03 to approve the particular form of any proposed amendment, but
it shall be sufficient if such consent shall approve the substance thereof. The
manner of obtaining such consents and of evidencing the authorization of the
execution thereof by Holders shall be subject to such reasonable regulations as
the Trustee may prescribe.

         (e)      Notwithstanding anything to the contrary in any Servicing
Agreement, the Trustee shall not consent to any amendment of any Servicing
Agreement except pursuant to the standards provided in this Section with respect
to amendment of this Agreement.

owned by the Depositor, the Master Servicer, the Securities Administrator, the
Trustee, any Servicer or any Affiliates thereof are not to be counted so long as

         3.       That the Purchaser is not a "disqualified organization" within
                  the meaning of Section 860E(e)(5) of the Internal Revenue Code

                  that is exempt from federal income tax unless such
                  organization is subject to the tax on unrelated business
                  income imposed by Code Section 511.

         4.       That the Purchaser either (x) is not, and on ________________

                  delivers to the Certificate Registrar an opinion of counsel (a
                  "Benefit Plan Opinion") satisfactory to the Certificate
                  Registrar, and upon which the Certificate Registrar, the
                  Trustee, the Master Servicer, the Depositor and Securities
                  Administrator shall be entitled to rely, to the effect that
                  the purchase or holding of such Residual Certificate by the
                  Investor will not result in any non-exempt prohibited
                  transactions under Title I of ERISA or Section 4975 of the
                  Code and will not subject the Certificate Registrar, the

                  Administrator to any obligation in addition to those

                  be permitted to be made to any person unless the Certificate

                  transferee containing the representations in paragraphs 3 and
                  4 hereof.

                  Certificate.

                  any person or entity (i) as to which the Purchaser has actual

                  paragraph 6 or paragraph 10 hereof are not satisfied or that
                  the Purchaser has reason to believe does not satisfy the
                  requirements set forth in paragraph 7 hereof, and (ii) without
                  obtaining from the prospective Purchaser an affidavit
                  substantially in this form and providing to the Trustee and

                  in excess of any cash flows generated by the interest and that
                  it intends to pay taxes associated with holding such Residual

                  accordance with the requirements of the Code and the
                  regulations promulgated thereunder and that such transfer of a

                  that are treated as United States persons prior to such date
                  and elect to continue to be treated as United States persons.

                  person" of each REMIC created by the Trust Fund pursuant to
                  the Pooling and Servicing Agreement.

affidavit of ____________________ (the "Transferee"), and has no actual
knowledge that such affidavit is not true and has no reason to believe that the
information contained in paragraph 7 thereof is not true, and has no reason to
believe that the Transferee has the intention to impede the assessment or
collection of any federal, state or local taxes legally required to be paid with
respect to a Residual Certificate. In addition, the Transferor has conducted a
reasonable investigation at the time of the transfer and found that the
Transferee had historically paid its debts as they came due and found no
significant evidence to indicate that the Transferee will not continue to pay
its debts as they become due.

Dear Sirs:

         In connection with our proposed purchase of $______________ principal
amount of Sequoia Mortgage Trust 2003-7 Mortgage Pass-Through Certificates (the
"Privately Offered Certificates") of Sequoia Residential Funding, Inc. (the
"Depositor"), we confirm that:

(1)      We understand that the Privately Offered Certificates have not been,
         and will not be, registered under the Securities Act of 1933, as
         amended (the "Securities Act"), and may not be sold except as permitted
         in the following sentence. We agree, on our own behalf and on behalf of
         any accounts for which we are acting as hereinafter stated, that if we
         should sell any Privately Offered Certificates within two years of the
         later of the date of original issuance of the Privately Offered
         Certificates or the last day on which such Privately Offered
         Certificates are owned by the Depositor or any affiliate of the
         Depositor we will do so only (A) to the Depositor, (B) to "qualified
         institutional buyers" (within the meaning of Rule 144A under the
         Securities Act) in accordance with Rule 144A under the Securities Act
         ("QIBs"), (C) pursuant to the exemption from registration provided by
         Rule 144 under the Securities Act, or (D) to an institutional
         "accredited investor" within the meaning of Rule 501(a)(1), (2), (3) or
         (7) of Regulation D under the Securities Act that is not a QIB (an
         "Institutional Accredited Investor") which, prior to such transfer,
         delivers to the Certificate Registrar under the Pooling and Servicing
         Agreement, dated as of November 1, 2003, by and among Sequoia
         Residential Funding, Inc., as Depositor, Wells Fargo Bank Minnesota,
         National Association, as Master Servicer and as Securities
         Administrator, and HSBC Bank USA, as Trustee, a signed letter in the
         form of this letter; and we further agree, in the capacities stated
         above, to provide to any person purchasing any of the Privately Offered
         Certificates from us a notice advising such purchaser that resales of
         the Privately Offered Certificates are restricted as stated herein.

(2)      We understand that, in connection with any proposed resale of any
         Privately Offered Certificates to an Institutional Accredited Investor,
         we will be required to furnish to the Certificate Registrar a
         certification from such transferee in the form hereof to confirm that
         the proposed sale is being made pursuant to an exemption from, or in a
         transaction not subject to, the registration requirements of the
         Securities Act. We further understand that the Privately Offered
         Certificates purchased by us will bear a legend to the foregoing
         effect.

                                       I-1



(3)      We are acquiring the Privately Offered Certificates for investment
         purposes and not with a view to, or for offer or sale in connection
         with, any distribution in violation of the Securities Act. We have such
         knowledge and experience in financial and business matters as to be
         capable of evaluating the merits and risks of our investment in the
         Privately Offered Certificates, and we and any account for which we are
         acting are each able to bear the economic risk of such investment.

(4)      We are an Institutional Accredited Investor and we are acquiring the
         Privately Offered Certificates purchased by us for our own account or
         for one or more accounts (each of which is an Institutional Accredited
         Investor) as to each of which we exercise sole investment discretion.

(5)      We have received such information as we deem necessary in order to make
         our investment decision.

(6)      If we are acquiring ERISA-Restricted Certificates, we understand that
         in accordance with ERISA, the Code and the Exemption, no Plan and no
         person acting on behalf of such a Plan may acquire such Certificate
         except in accordance with Section 3.03(d) of the Pooling and Servicing
         Agreement.

         Terms used in this letter which are not otherwise defined herein have
the respective meanings assigned thereto in the Pooling and Servicing Agreement.
