         This POOLING AND SERVICING AGREEMENT, dated as of April 1, 2004 (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, 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 Mortgage Loans from the Seller and at
the Closing Date is the owner of the 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
Mortgage Loans, 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 and the assets held in the Reserve Fund)
be treated for federal income tax purposes as comprising two real estate
mortgage investment conduits (each, a "REMIC" or, in the alternative, the
"Lower-Tier REMIC" and the "Upper-Tier REMIC," respectively). Each Certificate,
other than the Class A-R Certificate and the 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. Further, the Class X-1 Certificate represents the
right to receive the Class X-1 Additional Amount, as well as payments from the
Class X-2 Sub Account 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 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, 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 Upper-Tier REMIC shall hold as its assets the Lower-Tier
Interests other than the LT-R Interest.

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

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

(2)      The LT-R Interest is the sole class of residual interest 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
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 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
shall be distributed as principal on the Lower-Tier Interests as follows:

                  (i) First, to the LT-1 through LT-42 Interests until the
         aggregate of the Class Principal Amounts of such Lower-Tier Interests
         equals the Class Principal Amount of the Class A Certificate, in
         ascending order of their numerical designation until the Class
         Principal Amount of each such Lower-Tier Interest is reduced to zero;

                  (ii) second, to the Class LT-B1 Interest until its Class
         Principal Amount equals the Class Principal Amount of the Class B-1
         Certificate;

                  (iii) third, to the Class LT-B2 Interest until its Class
         Principal Amount equals the Class Principal Amount of the Class B-2
         Certificate;

                  (iv) fourth, to the Class LT-B3 Interest until its Class
         Principal Amount equals the Class Principal Amount of the Class B-3
         Certificate;

                  (v) fifth, to the Class LT-B4 Interest until its Class
         Principal Amount equals the Class Principal Amount of the Class B-4
         Certificate;

                  (vi) sixth, to the Class LT-B5 Interest until its Class
         Principal Amount equals the Class Principal Amount of the Class B-5
         Certificate;

                  (vii) seventh, to the Class LT-B6 Interest until its Class
         Principal Amount equals the Class Principal Amount of the Class B-6
         Certificate;

                  (viii) finally, to the Class LT-R Interest, any remaining
         amounts.

    (1)  The Certificate Interest Rate with respect to any Distribution Date
         (and the related Accrual Period) for the Class A Certificates is a per
         annum rate equal to the least of (i) Six-Month LIBOR plus 0.260%, (ii)
         the Net WAC and (iii) 11.50%; provided, however, if a Non-Redemption
         Event occurs, then the per annum rate calculated pursuant to clause (i)
         above with respect to the Class A Certificates will be Six-Month LIBOR
         plus 0.520% for all Distribution Dates thereafter, commencing with the
         Distribution Date related to the Six-Month LIBOR Determination Date
         immediately following such Non-Redemption Event.

    (2)  The Class X-1 Certificate is an interest only Class. With respect to
         any Distribution Date (and the related Accrual Period), the Class X-1
         Certificate is entitled to receive a specified portion of the interest
         accrued on each of Lower-Tier Interests LT-1 through LT-42 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 Net WAC for such Distribution Date over the Certificate Interest
         Rate for the Class A Certificates for such Distribution Date
         (multiplied by a fraction, the numerator of which is 21 and the
         denominator of which is 30 for the first Distribution Date only).

    (4)  The Class X-2 Certificate is an interest only Class. The Certificate
         Interest Rate with respect to any Distribution Date (and the related
         Accrual Period) for the Class X-2 Certificates is a per annum rate
         equal to the excess of the Adjusted Net WAC over the Certificate
         Interest Rate for the Class A Certificates. For purposes of the REMIC
         Provisions, with respect to any Distribution Date (and the related
         Accrual Period), the foregoing rate is intended to represent a
         specified portion of the interest accrued on each of Lower-Tier
         Interests LT-1 through LT-42, in each case, at a rate equal to the
         excess, if any, of (i) the Net WAC for such Distribution Date over (ii)
         the sum of (a) the Certificate Interest Rate on the Class A
         Certificates for such Distribution Date (multiplied by a fraction, the
         numerator of which is 21 and the denominator of which is 30 for the
         first Distribution Date only) and (b) for any Distribution Date on
         which the Class X-1 Certificate is entitled to a portion of the
         interest accrued on such Lower-Tier Interest, 0.80%.

    (5)  The Class Notional Amount of the Class X-2 Certificates with respect to
         any Distribution Date will equal the Class Principal Amount of the
         Class A Certificates immediately before such Distribution Date. The
         initial Class Notional Amount of the Class X-2 Certificates is
         $799,511,000.

    (6)  The Certificate Interest Rate with respect to any Distribution Date
         (and the related Accrual Period) for the Class X-B Certificates will be
         equal to the excess of the Net WAC over the weighted average of the
         Certificate Interest Rates on the Class B-1 and Class B-2 Certificates
         (multiplied by a fraction, the numerator of which is 21 and the
         denominator of which is 30 for the first Distribution Date only).

    (7)  The Class X-B Certificate is an interest only Certificate and for any
         Distribution Date the Class X-B Certificate shall bear interest at the
         interest rate described above on a Class Notional Amount equal to the
         sum of the Class Principal Amounts of the Class B-1 and Class B-2
         Certificates immediately before such Distribution Date. The initial
         Class Notional Amount of the Class X-B Certificates is $22,962,000.

    (8)  The Certificate Interest Rate with respect to any Distribution Date
         (and the related Accrual Period) for the Class B-1 Certificates is the
         per annum rate equal to the least of (i) One-Month LIBOR plus 0.500%,
         (ii) the Net WAC and (iii) 11.50%; provided, however, if a
         Non-Redemption Event occurs, then the per annum rate calculated
         pursuant to clause (i) above with respect to the Class B-1 Certificates
         will be One-Month LIBOR plus 0.750% for all Distribution Dates
         thereafter, commencing with the Distribution Date immediately following
         such Non-Redemption Event.

    (9)  The Certificate Interest Rate with respect to any Distribution Date
         (and the related Accrual Period) for the Class B-2 Certificates is the
         per annum rate equal to the least of (i) One-Month LIBOR plus 0.900%,
         (ii) the Net WAC and (iii) 11.50%; provided, however, if a
         Non-Redemption Event occurs, then the per annum rate calculated
         pursuant to clause (i) above with respect to the Class B-2 Certificates
         will be One-Month LIBOR plus 1.350% for all Distribution Dates
         thereafter, commencing with the Distribution Date immediately following
         such Non-Redemption Event.

    (10) The Certificate Interest Rates with respect to any Distribution Date
         (and the related Accrual Period) for the Class B-3, Class B-4, Class
         B-5 and Class B-6 Certificates will equal the Net WAC.

    (11) The Certificate Interest Rate with respect to any Distribution Date
         (and the related Accrual Period) for the Class A-R Certificate will
         equal the Net WAC.

    (12) The Class LT-R Certificate does not have a Class Principal Amount or a
         Certificate Interest Rate.

         As of the Cut-off Date, the Mortgage Loans had an Aggregate Stated
Principal Balance of $835,003,083.75.

Officer, as the case may be, and delivered to the Trustee or the Master
Servicer, as required hereby.

         One-Month LIBOR: With respect to the first Accrual Period, the Initial
One-Month LIBOR Rate. With respect to each subsequent Accrual Period, a per
annum rate determined on the LIBOR Determination Date for the Class B-1 and
Class B-2 Certificates in the following manner by the Securities Administrator
on the basis of the "Interest Settlement Rate" set by the BBA for one-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

such LIBOR Determination Date, One-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 One-Month LIBOR by the Securities
Administrator and the Securities Administrator's subsequent calculation of the
Certificate Interest Rate applicable to the Class B-1 and Class B-2 Certificates
for the relevant Accrual Period, in the absence of manifest error, will be final
and binding.

counsel concerning the transfer of any Residual Certificate or concerning
certain matters with respect to the Employee Retirement Income Security Act of
1974, as amended ("ERISA"), or the taxation, or the federal income tax status,
of each REMIC.

         Original Applicable Credit Support Percentage: With respect to each

interest in the undivided beneficial ownership interest in the Trust Fund
evidenced by all Certificates of the same Class as such Certificate. With
respect to any Certificate other than a Notional Certificate or the Class A-R
and Class LT-R Certificates, the Percentage Interest evidenced thereby shall
equal the initial Certificate Principal Amount thereof divided by the initial
Class Principal Amount of all Certificates of the same Class. With respect to
each of the Class A-R and the Class LT-R Certificates, the Percentage Interest
evidenced thereby shall be as specified on the face thereof, or otherwise, be

for that Distribution Date; (iii) from May 2016 through April 2017, the Senior
Percentage plus 40% of the Subordinate Percentage for that Distribution Date;
(iv) from May 2017 through April 2018, the Senior Percentage plus 20% of the

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 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 Senior Prepayment Percentage for such
Distribution Date shall be limited to the percentage necessary to reduce that
Class Principal Amount to zero.

         Senior Principal Distribution Amount: With respect to any Distribution
Date, the sum of:

                  received with respect to that Mortgage Loan.

                  (3) the Senior Prepayment Percentage of the amounts described
         in clauses (b), (c), (d) and (g) of the definition of "Principal
         Distribution Amount".

related Due Period.

         Servicing Fee Rate: With respect to each Mortgage Loan and any
Distribution Date, the rate specified in the related Servicing Agreement.

Six-Month LIBOR Rate. With respect to each subsequent Accrual Period, a per

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 Certificates for the
relevant Accrual Period, in the absence of manifest error, will be final and
binding.

Trustee shall be held by the Master Servicer or the applicable Servicer in trust
for the benefit of the Trustee and the Certificateholders.

         (d) Each of the parties hereto acknowledges that each Custodian shall
perform the applicable review of the related Mortgage Loans and respective
certifications as provided in the related Custody Agreement.

         (e) Upon execution of this Agreement, the Depositor hereby delivers to
the Trustee and the Trustee acknowledges receipt of the Acknowledgements,
together with the related Purchase Agreements, Servicing Agreements and the
Mortgage Loan Purchase and Sale Agreement.

         Section 2.03 Representations and Warranties of the Depositor.

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

                  (i) the Depositor is a corporation duly organized, validly
         existing and in good standing under the laws governing its creation and
         existence and has full corporate power and authority to own its
         property, to carry on its business as presently conducted, to enter
         into and perform its obligations under this Agreement, and to create
         the trust pursuant hereto;

                  (ii) the execution and delivery by the Depositor of this
         Agreement have been duly authorized by all necessary corporate action
         on the part of the Depositor; neither the execution and delivery of
         this Agreement, nor the consummation of the transactions herein
         contemplated, nor compliance with the provisions hereof, will conflict
         with or result in a breach of, or constitute a default under, any of
         the provisions of any law, governmental rule, regulation, judgment,
         decree or order binding on the Depositor or its properties or the
         certificate of incorporation or bylaws of the Depositor;

                  (iii) the execution, delivery and performance by the Depositor
         of this Agreement and the consummation of the transactions contemplated
         hereby do not require the consent or approval of, the giving of notice
         to, the registration with, or the taking of any other action in respect
         of, any state, federal or other governmental authority or agency,
         except such as has been obtained, given, effected or taken prior to the
         date hereof;

                  (iv) this Agreement has been duly executed and delivered by
         the Depositor and, assuming due authorization, execution and delivery
         by the Trustee, the Master

         Servicer and the Securities Administrator, constitutes a valid and
         binding obligation of the Depositor enforceable against it in
         accordance with its terms except as 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 equity or at law;

                  (v) there are no actions, suits or proceedings pending or, to
         the knowledge of the Depositor, threatened or likely to be asserted
         against or affecting the Depositor, before or by any court,
         administrative agency, arbitrator or governmental body (A) with respect
         to any of the transactions contemplated by this Agreement or (B) with
         respect to any other matter which in the judgment of the Depositor will
         be determined adversely to the Depositor and will if determined
         adversely to the Depositor materially and adversely affect it or its
         business, assets, operations or condition, financial or otherwise, or
         adversely affect its ability to perform its obligations under this
         Agreement;

                  (vi) immediately prior to the transfer and assignment of the
         Mortgage Loans to the Trustee, the Depositor was the sole owner of
         record and holder of each Mortgage Loan, and the Depositor had good and
         marketable title thereto, and had full right to transfer and sell each
         Mortgage Loan to the Trustee free and clear, subject only to (1) liens
         of current real property taxes and assessments not yet due and payable
         and, if the related Mortgaged Property is a condominium unit, any lien
         for common charges permitted by statute, (2) covenants, conditions and
         restrictions, rights of way, easements and other matters of public
         record as of the date of recording of such Mortgage acceptable to
         mortgage lending institutions in the area in which the related
         Mortgaged Property is located and specifically referred to in the
         lender's title insurance policy or attorney's opinion of title and
         abstract of title delivered to the originator of such Mortgage Loan,
         and (3) such other matters to which like properties are commonly
         subject which do not, individually or in the aggregate, materially
         interfere with the benefits of the security intended to be provided by
         the Mortgage, of any encumbrance, equity, participation interest, lien,
         pledge, charge, claim or security interest, and had full right and
         authority, subject to no interest or participation of, or agreement
         with, any other party, to sell and assign each Mortgage Loan pursuant
         to this Agreement;

                  (vii) This Agreement creates a valid and continuing security
         interest (as defined in the applicable Uniform Commercial Code (the
         "UCC"), in the Mortgage Loans in favor of the Trustee, which security
         interest is prior to all other liens, and is enforceable as such
         against creditors of and purchasers from the Depositor;

                  (viii) The Mortgage Loans constitute "instruments" within the
         meaning of the applicable UCC;

                  (ix) Other than the security interest granted to the Trustee
         pursuant to this Agreement, the Depositor has not pledged, assigned,
         sold, granted a security interest in, or otherwise conveyed any of the
         Mortgage Loans. The Depositor has not authorized the filing of and is
         not aware of any financing statement against the Depositor 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 Mortgage Loans as of the Closing Date,
including representations and warranties that no Mortgage Loan is a "high-cost
home loan" as defined under any local, state, or federal laws, and it is
intended that the Mortgage Loans (including any Replacement Mortgage Loans)
included in the Trust Fund satisfy such representations and warranties. The
Depositor, for the benefit of the Trustee and the 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.

         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 (i) discovery or receipt by the
Depositor of written notice of any materially defective document in a related
Trustee Mortgage File or, following the date of delivery to the Trustee of a
Custodian's Final Trust Receipt as required under any Custody Agreement, that a
document is missing from a related Trustee Mortgage File, or (ii) discovery by
the Depositor or 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

                                       41


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 (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 applicable
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. The applicable 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, each
applicable 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 for which it acts as Custodian, 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

                                       42


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 applicable 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, 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 [Reserved.]

         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 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).

                                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 Certificates will be evidenced by one or more certificates, beneficial
ownership of which will be held in the minimum denominations in Certificate
Principal Amount or Notional Amount specified in the Preliminary Statement to
this Agreement and in integral multiples of $1 in excess thereof, or in the
Percentage Interests specified in the Preliminary Statement to this Agreement,
as applicable.

         (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;

                                       45


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 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

                                       46


                  (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
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

                                       47


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 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 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

                                       49


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
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
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 or (ii) 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 (each such
event, a "Book-Entry Termination"), 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 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.

         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

         (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 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.

                    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 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) and (c), on each Distribution Date, the
Available Distribution Amount shall be withdrawn by the Securities Administrator

and Subordinate Certificates in the following order of priority:

                  (i) Concurrently, to the payment of the Interest Distribution

         (e) [Reserved].

         (f) [Reserved].

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, 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.

         (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) Subsequent Recoveries in respect of the Mortgage Loans shall be
distributed to the Certificates still outstanding, in accordance with Section
5.02, and the Class Principal Amount of each Class of Certificates then
outstanding that has been reduced due to application of a Realized Loss will be
increased, in order of seniority, by the amount of such Subsequent Recovery.

         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.

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

         (c) On any Distribution Date for which a Net WAC Shortfall exists with
respect to the Class A Certificates, the Securities Administrator shall
withdraw, to the extent of available funds therein, from the Class X-2 Sub
Account and the Class X-1 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) [Reserved].

         (e) On any Distribution Date for which a Net WAC Shortfall exists with
respect to the Class B-1 or Class B-2 Certificates, the Securities Administrator
shall withdraw, to the extent of available funds therein, from the Class X-B 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 Class X-1
Certificates, are used to make payments of any related Required Reserve Fund
Deposit (including any Class X-1 Additional

Amount for such Distribution Date), the Securities Administrator will withdraw
from the Class X-2 Sub Account, to the extent of amounts on deposit in such Sub
Account 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 X-1 Sub Account shall be for
the benefit of the Class X-1 Certificateholders; any earnings on amounts in the
Class X-2 Sub Account shall be for the benefit of the Class X-2
Certificateholders; and any earnings on amounts in the Class X-B 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 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.

       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.

         (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 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 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

         Except as otherwise provided in Section 6.01:

                  (i) Each of the Trustee and the Securities Administrator may
         request, and may rely and shall be protected in acting or 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, bond or other paper

                  (iii) Neither the Trustee nor the Securities Administrator
         shall be personally liable for any action taken, suffered or omitted by
         it in good faith and reasonably believed by it to be authorized or
         within the discretion or rights or powers conferred upon it by this
         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

         notice, request, consent, order, approval, bond or other paper or

         reasonable time to the Trustee or the Securities Administrator, as

                  (vii) The right of the Trustee and the Securities
         Administrator to perform any discretionary act enumerated in this
         Agreement shall not be construed as a duty, and neither the Trustee nor
         the Securities Administrator shall be answerable for other than its
         negligence or willful misconduct in the performance of such act; and

                  (viii) Neither the Trustee nor the Securities Administrator
         shall be required to give any bond or surety in respect of the
         execution of the Trust Fund created hereby or the powers granted
         hereunder.

         Section 6.03 Trustee and Securities Administrator Not Liable for
                      Certificates.

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
equity or at law. The Trustee and the Securities Administrator shall not be
accountable for the use or application by the Depositor of funds paid to the
Depositor in consideration of the assignment of the Mortgage Loans to the Trust
Fund by the Depositor or for the use or application of any funds deposited into
the Distribution Account or any other fund or account maintained with respect to

priority, perfection or sufficiency of the security for the Certificates issued
or intended to be issued hereunder. Except as otherwise provided herein, the
Trustee and the Securities Administrator shall have no responsibility for filing
any financing or continuation statement in any public office at any time or to

examination by federal or state authority and (iii) not an Affiliate of the
Master Servicer or any Servicer. If such corporation or national banking

corporation or national banking association shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so
published. In case at any time the Trustee shall cease to be eligible in
accordance with provisions of this Section, the Trustee shall resign immediately
in the manner and with the effect specified in Section 6.06.

         Section 6.06 Resignation and Removal of Trustee and the Securities

successor securities administrator, as applicable, by written instrument, one

trustee or successor securities administrator, as applicable, and one copy to
the Master Servicer. If no successor trustee or successor securities
administrator shall have been so appointed and shall have accepted appointment
within 30 days after the giving of such notice of resignation, the resigning
Trustee or resigning Securities Administrator, as applicable, may petition any
court of competent jurisdiction for the appointment of a successor trustee or
successor securities administrator, as applicable.

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 (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 with a rating, then the Depositor shall remove the Trustee or the

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

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.

         (b) No successor trustee shall accept appointment as provided in this

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:

                  (i) all powers, duties, obligations and rights conferred upon

         shall be exercised solely by the Trustee;

                                       70


                  (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.

         (g) The Trust shall pay the reasonable compensation of the co-trustees

         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

         (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 each
Custody Agreement, including the reasonable compensation and the expenses and

or administration of the trusts created hereunder or in connection with the

                  (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.

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

part of the Trust Fund and shall distribute it as provided in this Agreement.

         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

         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,

         any Rating Agency reduces or withdraws or threatens to reduce or

         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

         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;

         which such representation or warranty was incorrect shall not have been
         eliminated or cured within 30 days after the date on which written

         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 (viii) 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, if so directed by Certificateholders evidencing more
than 50% of the Class Principal Amount (or Class Notional Amount) of each Class
of Certificates, or upon the occurrence of an Event of Default described in
clause (ix) of this Section, shall, 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.

         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.

                                       75


         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 in accordance with Section 5.04; 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 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

                                       76


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.

         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

Pooling and Servicing Agmt.

                                       77


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 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

                                       78


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 or, if shorter, within
the period of time required under the rules of the Securities and Exchange
Commission (the "Commission"), the Depositor shall, on behalf of the Trust and
in accordance with industry standards, file with the Commission via the
Electronic Data Gathering and Retrieval System (EDGAR), a Form 8-K (or such
other form prescribed by the Commission) with a copy of the report to the
Certificateholders for such Distribution Date as an exhibit thereto. Prior to
March 30, 2005 (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, 2005 (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
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
filing on Form 8-K (or other prescribed form) 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 VII

                         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

                                       80


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.

         (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 Clean-Up Call Price or (b) state in such notice that
the Clean-Up Call 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 Clean-Up Call Price.

         (d) The Depositor, the Master Servicer, each Servicer, the Securities
Administrator and each Custodian shall be reimbursed from the Redemption Price
or Clean-Up Call Price, as applicable, 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 related Custody
Agreement.

         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

                                       81


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 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
         or the Holder of the Class LT-R Certificate 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

                                       82


such other action in connection therewith as may be reasonably requested by the
Securities Administrator or any Servicer.

                          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 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

107174 Sequoia 2004-4
Pooling and Servicing Agmt.

                                       84


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.

         (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

107174 Sequoia 2004-4
Pooling and Servicing Agmt.

                                       85


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.

         (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 that is a member in good standing of MERS to serve as successor to the
Servicer; provided, however, that no Trustee consent or Rating Agency approval
shall be required if the successor servicer is GMAC or a Person that was a
Servicer on the Closing Date; provided, further, 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,

107174 Sequoia 2004-4
Pooling and Servicing Agmt.

                                       86


has succeeded the Servicer under the Servicing Agreement, which notice shall
also specify the name and address of any such successor servicer.

         (d) Unless otherwise specified herein, the provisions of Section
9.01(b) (relating to the Fannie Mae- and Freddie Mac- approval and MERS
membership of any successor servicer, the form of any servicing agreement to be
entered into by such successor servicer and the amount of compensation payable
thereunder) and the provisions of Section 9.01(c) (relating to notices to the
Trustee and the Rating Agencies) shall apply to any proposed transfer or
assignment by the Seller of its rights under any Servicing Agreement or of the
servicing thereunder or delegation of its rights or duties thereunder or any
portion thereof to any other Person other than GMAC or the initial Servicer
under such Servicing Agreement; provided that the Seller shall not be required
to provide prior notice to anyone other than the Master Servicer of any transfer
of servicing that occurs within three months following the Closing Date to GMAC
or to an entity that is a Servicer on the Closing Date. In addition, 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 to a
successor servicer other than GMAC or a Person that was a Servicer on the
Closing Date without the prior written consent of the Master Servicer, which
consent shall not be unreasonably withheld.

         The Seller has advised the Depositor, the Trustee and the Master
Servicer that it will transfer the servicing of the Mortgage Loans purchased
under the Seller's Purchase, Warranties and Interim Servicing Agreement, dated
as of January 1, 2004 between GreenPoint and GMAC and currently serviced by
GreenPoint to GMAC on or about July 1, 2004 (the "GMAC Servicing Transfer Date")
pursuant to a servicing agreement that will contain provisions for
scheduled/scheduled servicing of such Mortgage Loans in accordance with
customary securitization standards (including express provisions that prohibit
GMAC from taking actions with respect to Mortgage Loans it is servicing that
could cause an Adverse REMIC Event) and that are consistent with the provisions
of this Agreement and providing for a Servicing Fee that is not greater than the
Servicing Fee payable to GreenPoint. Not less than 10 Business Days prior to the
GMAC Servicing Transfer Date, the Seller shall furnish the Depositor, the
Trustee and the Master Servicer with an executed copy of such servicing
agreement together with (i) one or more assignment agreements assigning the
rights of the Seller thereunder to the Depositor, and from the Depositor to the
Trustee, if applicable, and (ii) either (x) Rating Agency approval of such
servicing transfer and servicing agreement or (y) a certificate of an authorized
officer of the Seller to the effect that the servicing agreement satisfies the
requirements of this Agreement. Neither the Trustee nor the Master Servicer
shall have any responsibility for determining whether such servicing agreement
complies with the provisions of this Agreement, and each of them may, in
executing any such assignment agreement rely fully on the Rating Agency approval
or Seller certification.

         In connection with any transfer of servicing (whether to GMAC, another
initial Servicer, or otherwise), the Seller shall, at its cost and expense, take
such steps, or cause the terminated Servicer to take such steps, as may be
necessary or appropriate to effectuate and evidence the transfer of the
servicing of the Mortgage Loans to such successor servicer, including, but not
limited to, the following: (A) to the extent required by the terms of the
Mortgage Loans and by applicable federal and state laws and regulations, the
Seller shall cause the prior Servicer to timely mail to each obligor under a
Mortgage Loan any required notices or disclosures

107174 Sequoia 2004-4
Pooling and Servicing Agmt.

                                       87


describing the transfer of servicing of the Mortgage Loans to the successor
servicer; (B) prior to the effective date of such transfer of servicing, the
Seller shall cause the prior Servicer to transmit to any related insurer
notification of such transfer of servicing; (C) on or prior to the effective
date of such transfer of servicing, the Seller shall cause the prior Servicer to
deliver to the successor servicer all Mortgage Documents and any related records
or materials; (D) on or prior to the effective date of such transfer of
servicing, the Seller shall cause the prior Servicer to transfer to the
successor servicer all funds held by the prior Servicer in respect of the
Mortgage Loans; (E) on or prior to the effective date of such transfer of
servicing, the Seller shall cause the prior Servicer to, after the effective
date of the transfer of servicing to the successor servicer, continue to forward
to such successor servicer, within one Business Day of receipt, the amount of
any payments or other recoveries received by the prior Servicer, and to notify
the successor servicer of the source and proper application of each such payment
or recovery; and (F) the Seller shall cause the prior Servicer to, after the
effective date of transfer of servicing to the successor servicer, continue to
cooperate with the successor servicer to facilitate such transfer in such manner
and to such extent as the successor servicer may reasonably request.
Notwithstanding the foregoing, the prior Servicer shall be obligated to perform
the items listed above to the extent provided in the Servicing Agreement.

         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;

                  (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;

                                       89


                  (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 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 or its Affiliate whose primary business is the
servicing of conventional residential mortgage loans 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
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, 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

                                       91


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 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

                                       92


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.

         Section 9.10 Master Servicer Fidelity Bond and Master Servicer Errors
                      and Omissions Insurance Policy.

         The Master Servicer, at its expense, shall maintain in effect a blanket
fidelity bond and an errors and omissions insurance policy, affording coverage
with respect to all directors, officers, employees and other Persons acting on
such Master Servicer's behalf, and covering errors and omissions in the
performance of the Master Servicer's obligations hereunder. The errors and
omissions insurance policy and the fidelity bond shall be in such form and
amount generally acceptable for entities serving as master servicers or
trustees.

                              REMIC ADMINISTRATION

         Section 10.01 REMIC Administration.

         (a) REMIC elections as set forth in the Preliminary Statement to this
Agreement 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 to
this Agreement.

         (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 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

Pooling and Servicing Agmt.

                                       93


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 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

107174 Sequoia 2004-4
Pooling and Servicing Agmt.

                                       94


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 Distribution 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, Class B-1 and Class B-2 Certificate 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 Holder of the Class LT-R Certificate shall act as "tax matters
person" with respect to the Lower-Tier REMIC and shall act as agent for the
Holder of the Class A-R Certificate as "tax matters person" with respect to the
Upper-Tier REMIC and the Securities Administrator shall act as agent for the
Holder of the Class LT-R Certificate in such roles, unless and until another
party is so designated by the Holder of the Class LT-R Certificate.

         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

107174 Sequoia 2004-4
Pooling and Servicing Agmt.

                                       95


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

107174 Sequoia 2004-4
Pooling and Servicing Agmt.

                                       96


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 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

         3.       That the Purchaser is not a "disqualified organization" within
                  the meaning of Section 860E(e)(5) of the Internal Revenue Code
                  of 1986, as amended (the "Code") and will not be a

                  organization is subject to the tax on unrelated business
                  income imposed by Code Section 511.

                  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
                  Trustee, the Depositor, the Master Servicer or the Securities
                  Administrator to any obligation in addition to those
                  undertaken by such entities in the Pooling and Servicing
                  Agreement, which opinion of counsel shall not be an expense of
                  the Trust Fund or any of the above parties.

         5.       That the Purchaser hereby acknowledges that under the terms of
                  the Pooling and Servicing Agreement, dated as of April 1, 2004
                  (the "Agreement"), by and among Sequoia Residential Funding,

                  Residual Certificates shall be permitted to be made to any
                  person unless the Certificate Registrar and Trustee have
                  received a certificate from such transferee containing the
                  representations in paragraphs 3 and 4 hereof.

         6.       That the Purchaser does not hold REMIC residual securities as
                  nominee to facilitate the clearance and settlement of such
                  securities through electronic book-entry changes in accounts
                  of participating organizations (such entity, a "Book-Entry
                  Nominee").

         7.       That the Purchaser does not have the intention to impede the
                  assessment or collection of any federal, state or local taxes
                  legally required to be paid with respect to such Residual
                  Certificate.

         8.       That the Purchaser will not transfer a Residual Certificate to
                  any person or entity (i) as to which the Purchaser has actual
                  knowledge that the requirements set forth in paragraph 3,
                  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
                  the Certificate Registrar a written statement substantially in
                  the form of Exhibit C to the Agreement.

         9.       That the Purchaser understands that, as the holder of a
                  Residual Certificate, the Purchaser may incur tax liabilities
                  in excess of any cash flows generated by the interest and that
                  it intends to pay taxes associated with holding such Residual
                  Certificate as they become due.

         10.      That the Purchaser (i) is not a Non-U.S. Person or (ii) is a
                  Non-U.S. Person that holds a Residual Certificate in

      _______________________ (the "Transferor") has reviewed the attached
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 2004-4 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 April 1, 2004, by and among Sequoia Residential
      Funding, Inc., as Depositor, Wells Fargo Bank, 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.

(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.
