in lieu of delivering such original recorded Mortgage referred to in clause (ii)
above, deliver to the Trustee (or a Custodian on behalf of the Trustee) a copy
thereof, provided that the Depositor certifies that the original Mortgage has
been delivered to a title insurance company for recordation after receipt of its
policy of title insurance or binder therefor (which may be a certificate
relating to a master policy of title insurance), and (b) in lieu of delivering
the completed assignment in recordable form referred to in clause (iii) above to
the Trustee (or a Custodian on behalf of the Trustee), deliver such assignment
to the Trustee (or a Custodian on behalf of the Trustee) completed except for
recording information. In all such instances, the Depositor will deliver the
original recorded Mortgage and completed assignment (if applicable) to the
Trustee (or a Custodian on behalf of the Trustee) promptly upon receipt of such
Mortgage. In instances where an original recorded Mortgage has been lost or
misplaced, the Depositor or the related title insurance company may deliver, in
lieu of such Mortgage, a copy of such Mortgage bearing recordation information
and certified as true and correct by the office in which recordation thereof was
made. In instances where the original or a copy of the title insurance policy
referred to in clause (vi) above (which may be a certificate relating to a
master policy of title insurance) pertaining to the Mortgaged Property relating
to a Mortgage Loan cannot be delivered by the Depositor to the Trustee (or a
Custodian on behalf of the Trustee) prior to or concurrently with the execution
and delivery of this Agreement because such policy is not yet available, the
Depositor may, in lieu of delivering the original or a copy of such title
insurance referred to in clause (vi) above, deliver to the Trustee (or a
Custodian on behalf of the Trustee) a binder with respect to such policy (which
may be a certificate relating to a master policy of title insurance) and deliver
the original or a copy of such policy (which may be a certificate relating to a
master policy of title insurance) to the Trustee (or a Custodian on behalf of
the Trustee) within 180 days of the Closing Date, in instances where an original
assumption, modification, buydown or conversion-to-fixed- interest-rate
agreement cannot be delivered by the Depositor to the Trustee (or a Custodian on
behalf of the Trustee) prior to or concurrently with the execution and delivery
of this Agreement, the Depositor may, in lieu of delivering the original of such
agreement referred to in clause (iv) above, deliver a certified copy thereof.

            To the extent not already recorded, except with respect to any
Mortgage Loan for which MERS is identified on the Mortgage or on a properly
recorded assignment of the Mortgage as the mortgagee of record, the Servicer, at
the expense of the Sponsor shall promptly (and in no event later than five
Business Days following the later of the Closing Date and the date of receipt by
the Servicer of the recording information for a Mortgage) submit or cause to be
submitted for recording, at no expense to any Trust REMIC, in the appropriate
public office for real property records, each Assignment delivered to it
pursuant to (iii) above. In the event that any such Assignment is lost or
returned unrecorded because of a defect therein, the Servicer, at


                                       53
<PAGE>

the expense of the Sponsor, shall promptly prepare or cause to be prepared a
substitute Assignment or cure or cause to be cured such defect, as the case may
be, and thereafter cause each such Assignment to be duly recorded.
Notwithstanding the foregoing, but without limiting the requirement that such
Assignments be in recordable form, neither the Servicer nor the Trustee shall be
required to submit or cause to be submitted for recording any Assignment
delivered to it or a Custodian pursuant to (iii) above if such recordation shall
not, as of the Closing Date, be required by the Rating Agencies, as a condition
to their assignment on the Closing Date of their initial ratings to the
Certificates, as evidenced by the delivery by the Rating Agencies of their
ratings letters on the Closing Date; provided, however, notwithstanding the
foregoing, the Servicer shall submit each Assignment for recording, at no
expense to the Trust Fund or the Servicer, upon the earliest to occur of: (A)
reasonable direction by Holders of Certificates entitled to at least 25% of the
Voting Rights, (B) the occurrence of a Servicer Event of Default, (C) the
occurrence of a bankruptcy, insolvency or foreclosure relating to the Sponsor,
(D) the occurrence of a servicing transfer as described in Section 7.02 of this
Agreement and (E) with respect to any one Assignment the occurrence of a
foreclosure relating to the Mortgagor under the related Mortgage.
Notwithstanding the foregoing, if the Sponsor fails to pay the cost of recording
the Assignments, such expense will be paid by the Servicer and the Servicer
shall be reimbursed for such expenses by the Trust as Servicing Advances.

            In connection with the assignment of any Mortgage Loan registered on
the MERS System, the Depositor further agrees that it will cause, within 30
Business Days after the Closing Date, the MERS System to indicate that such
Mortgage Loans have been assigned by the Depositor to the Trustee in accordance
with this Agreement for the benefit of the Certificateholders by including in
such computer files (a) the code in the field which identifies the specific
Trustee and (b) the code in the field "Pool Field" which identifies the series
of the Certificates issued in connection with such Mortgage Loans. The Depositor
further agrees that it will not, and will not permit the Servicer to, and the
Servicer agrees that it will not and will not permit a Sub-Servicer to, alter
the codes referenced in this paragraph with respect to any Mortgage Loan during
the term of this Agreement unless and until such Mortgage Loan is repurchased in
accordance with the terms of this Agreement.

             With respect to a maximum of approximately 5.00% of the Original
Mortgage Loans, by outstanding principal balance of the Original Mortgage Loans
as of the Cut-off Date, if any original Mortgage Note referred to in (i) above
cannot be located, the obligations of the Depositor to deliver such documents
shall be deemed to be satisfied upon delivery to the Trustee (or a Custodian on
behalf of the Trustee) of a photocopy of such Mortgage Note, if available, with
a lost note affidavit. If any of the original Mortgage Notes for which a lost
note affidavit was delivered to the Trustee (or a Custodian on behalf of the
Trustee) is subsequently located, such original Mortgage Note shall be delivered
to the Trustee (or a Custodian on behalf of the Trustee) within three Business
Days.

The Depositor shall deliver or cause to be delivered to the Trustee (or a
Custodian on behalf of the Trustee) promptly upon receipt thereof any other
original documents constituting a part of a Mortgage File received with respect
to any Mortgage Loan, including, but not limited to, any original documents
evidencing an assumption, modification, consolidation or extension of any
Mortgage Loan.


                                       54
<PAGE>

            All original documents relating to the Mortgage Loans that are not
delivered to the Trustee (or a Custodian on behalf of the Trustee) are and shall
be held by or on behalf of the Sponsor, the Depositor or the Servicer, as the
case may be, in trust for the benefit of the Trustee on behalf of the
Certificateholders. In the event that any such original document is required
pursuant to the terms of this Section to be a part of a Mortgage File, such
document shall be delivered promptly to the Trustee (or a Custodian on behalf of
the Trustee). Any such original document delivered to or held by the Depositor
that is not required pursuant to the terms of this Section to be a part of a
Mortgage File, shall be delivered promptly to the Servicer.

            Wherever it is provided in this Section 2.01 that any document,
evidence or information relating to a Mortgage Loan be delivered or supplied to
the Trustee, the Depositor shall do so by delivery thereof to the Trustee or a
Custodian on behalf of the Trustee.

            The parties hereto understand and agree that it is not intended that
any Mortgage Loan be included in the Trust that is a high-cost home loan as
defined by the Homeownership and Equity Protection Act of 1994 or any other
applicable predatory or abusive lending laws.

            The Depositor hereby directs the Trustee to execute, deliver and
perform its obligations under the Cap Contract on the Closing Date and
thereafter on behalf of the Trust and the Holders of the Floating Rate
Certificates. The Sponsor, the Depositor, the Servicer, the Trust Administrator
and the Holders of the Floating Rate Certificates by their acceptance of such
Certificates acknowledge and agree that the Trustee shall execute, deliver and
perform the Trust Fund's obligations under the Cap Contract and shall do so
solely in its capacity as Trustee of the Trust Fund and not in its individual
capacity. The Trustee shall not have any responsibility for the contents,
adequacy or sufficiency of the Cap contract, including, without limitation, any
representations and warranties contained therein.

            SECTION 2.02       Acceptance of the Trust Fund by the Trustee.

            Subject to the provisions of Section 2.01 and subject to any
exceptions noted on an exception report delivered by or on behalf of the
Trustee, the Trustee acknowledges receipt of the documents referred to in
Section 2.01 (other than such documents described in Section 2.01(iv)) above and
all other assets included in the definition of "Trust Fund" and declares that it
holds and will hold such documents and the other documents delivered to it
constituting the Mortgage File, and that it holds or will hold all such assets
and such other assets included in the definition of "Trust Fund" in trust for
the exclusive use and benefit of all present and future Certificateholders.

            The Trustee, by execution and delivery hereof, acknowledges receipt,
subject to the review described in the succeeding sentence, of the documents and
other property referred to in Section 2.01 and declares that the Trustee (or a
Custodian on behalf of the Trustee) holds and will hold such documents and other
property, including property yet to be received in the Trust Fund, in trust,
upon the trusts herein set forth, for the benefit of all present and future
Certificateholders. The Trustee or the related Custodian on its behalf shall,
for the benefit of the Trustee and the Certificateholders, review each Mortgage
File within 90 days after execution and delivery of this Agreement, to ascertain
that all required documents have been executed, received and recorded, if
applicable, and that such documents relate to the Mortgage Loans. If in the


                                       55
<PAGE>

course of such review the Trustee or the related Custodian on its behalf finds a
document or documents constituting a part of a Mortgage File to be defective in
any material respect, the Trustee or the related Custodian on its behalf shall
promptly so notify the Depositor, the Trust Administrator, the Sponsor, the
Servicer and, if such notice is from the related Custodian on the Trustee's
behalf, the Trustee. In addition, upon the discovery by the Depositor, the
Servicer, the Trust Administrator or the Trustee of a breach of any of the
representations and warranties made by the related Originator or the Sponsor in
the related Assignment Agreement in respect of any Mortgage Loan which
materially adversely affects such Mortgage Loan or the interests of the related
Certificateholders in such Mortgage Loan, the party discovering such breach
shall give prompt written notice to the other parties.

            The Depositor and the Trustee intend that the assignment and
transfer herein contemplated constitute a sale of the Mortgage Loans, the
related Mortgage Notes and the related documents, conveying good title thereto
free and clear of any liens and encumbrances, from the Depositor to the Trustee
in trust for the benefit of the Certificateholders and that such property not be
part of the Depositor's estate or property of the Depositor in the event of any
insolvency by the Depositor. In the event that such conveyance is deemed to be,
or to be made as security for, a loan, the parties intend that the Depositor
shall be deemed to have granted and does hereby grant to the Trustee a first
priority perfected security interest in all of the Depositor's right, title and
interest in and to the Mortgage Loans, the related Mortgage Notes and the
related documents, and that this Agreement shall constitute a security agreement
under applicable law.

             The Trustee may, concurrently with the execution and delivery hereof
or at any time thereafter, enter into a custodial agreement with a Custodian
pursuant to which the Trustee appoints a Custodian to hold the Mortgage Files on
behalf of the Trustee for the benefit of the Trustee and all present and future
Certificateholders, which may provide that the related Custodian shall, on
behalf of the Trustee, conduct the review of each Mortgage File required under
the first paragraph of this Section 2.02. Initially, Citibank West, FSB is
appointed as Custodian with respect to the related Mortgage Files of all the
related Mortgage Loans and, notwithstanding anything to the contrary herein, it
is understood that such initial Custodian shall be responsible for the review
contemplated in the second paragraph of this Section 2.02 and for all other
functions relating to the receipt, review, reporting and certification provided
for herein with respect to the Mortgage Files (other than ownership thereof for
the benefit of the Certificateholders and related duties and obligations set
forth herein).

            SECTION 2.03       Repurchase or Substitution of Mortgage Loans
                        by the Sponsor or the Depositor.

            (a)    Upon discovery or receipt of notice by the Depositor, the
Servicer, the Trust Administrator or the Trustee of any materially defective
document in, or that a document is missing from, a Mortgage File or of the
breach by the Originator or the Sponsor of any representation, warranty or
covenant under an Assignment Agreement in respect of any Mortgage Loan which
materially adversely affects the value of such Mortgage Loan or the interest
therein of the Certificateholders, the party so discovering or receiving notice
shall promptly notify the other parties to this Agreement, and the Trustee
thereupon shall promptly notify the related Originator and the Sponsor of such
defect, missing document or breach and request that the related Originator
deliver such missing document or cure such defect or that the


                                       56
<PAGE>

related Originator or the Sponsor, as applicable, cure such breach within 90
days from the date the related Originator or the Sponsor, as applicable, was
notified of such missing document, defect or breach, and if the related
Originator or Sponsor, as applicable, does not deliver such missing document or
cure such defect or breach in all material respects during such period, the
Trustee shall enforce the obligations of the related Originator or Sponsor, as
applicable, under the related Assignment Agreement (i) to repurchase such
Mortgage Loan from REMIC I at the Purchase Price within 90 days after the date
on which the Sponsor was notified (subject to Section 2.03(e)) of such missing
document, defect or breach, and (ii) to indemnify the Trust Fund in respect of
such missing document, defect or breach, in the case of each of (i) and (ii), if
and to the extent that the related Originator or Sponsor, as applicable, is
obligated to do so under the related Assignment Agreement. The Purchase Price
for the repurchased Mortgage Loan and any indemnification shall be remitted by
the related Originator or the Sponsor, as applicable, to the Servicer for
deposit into the Collection Account, and the Trust Administrator, upon receipt
of written notice from the Servicer of such deposit, shall give written notice
to the Trustee and the related Custodian that such deposit has taken place and
the Trustee shall release (or cause the related Custodian to release on its
behalf) to the related Originator or the Sponsor, as applicable, the related
Mortgage File, and the Trustee and the Trust Administrator shall execute and
deliver such instruments of transfer or assignment, in each case without
recourse, as the related Originator or the Sponsor, as applicable, shall furnish
to it and as shall be necessary to vest in the related Originator or the
Sponsor, as applicable, any Mortgage Loan released pursuant hereto, and the
Trustee and the Trust Administrator shall have no further responsibility with
regard to such Mortgage File. In furtherance of the foregoing, if the related
Originator or the Sponsor, as applicable, is not a member of MERS and
repurchases a Mortgage Loan which is registered on the MERS System, the related
Originator or the Sponsor, as applicable, pursuant to the related Assignment
Agreement at its own expense and without any right of reimbursement, shall cause
MERS to execute and deliver an assignment of the Mortgage in recordable form to
transfer the Mortgage from MERS to the related Originator or the Sponsor, as
applicable, and shall cause such Mortgage to be removed from registration on the
MERS System in accordance with MERS rules and regulations. In lieu of
repurchasing any such Mortgage Loan as provided above, if so provided in the
related Assignment Agreement the related Originator or the Sponsor, as
applicable, may cause such Mortgage Loan to be removed from REMIC I (in which
case it shall become a Deleted Mortgage Loan) and substitute one or more
Qualified Substitute Mortgage Loans in the manner and subject to the limitations
set forth in Section 2.03(d). It is understood and agreed that the obligation of
the related Originator or the Sponsor, as applicable, 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, and if and to the extent provided in the related
Assignment Agreement to perform any applicable indemnification obligations with
respect to any such omission, defect or breach, as provided in such Assignment
Agreement, shall constitute the only remedies respecting such omission, defect
or breach available to the Trustee or the Trust Administrator on behalf of the
Certificateholders.

            (b)    Notwithstanding anything to the contrary in this Section 2.03,
with respect to any breach by the related Originator or the Sponsor, as
applicable, of any representation and warranty which breach materially and
adversely affects the value of any Prepayment Charge or the interests of the
Certificateholders therein, the Trustee shall enforce the obligation of the
related Originator or the Sponsor, as applicable, to remedy such breach as
provided in the related


                                       57
<PAGE>

Assignment Agreement as follows: upon any Principal Prepayment with respect to
the affected Mortgage Loan, the related Originator or the Sponsor, as
applicable, shall pay or cause to be paid to the Purchaser the excess, if any,
of (x) the amount of such Prepayment Charge calculated as set forth in the
Mortgage Loan Schedule and (y) the amount collected from the Mortgagor in
respect of such Prepayment Charge.

            (c)    Within 90 days of the earlier of discovery by the Servicer or
receipt of notice by the Depositor of the breach of any representation, warranty
or covenant of the Servicer set forth in Section 2.05 which materially and
adversely affects the interests of the Certificateholders in any Mortgage Loan,
the Servicer shall cure such breach in all material respects.

            (d)    Any substitution of Qualified Substitute Mortgage Loans for
Deleted Mortgage Loans made pursuant to Section 2.03(a) must be effected prior
to the date which is two years after the Startup Day for REMIC I.

            As to any Deleted Mortgage Loan for which the related Originator or
the Sponsor, as applicable, substitutes a Qualified Substitute Mortgage Loan or
Loans, such substitution shall be effected by the related Originator or the
Sponsor, as applicable, delivering to the Trustee (or to the related Custodian
on behalf of the Trustee, as applicable), for such Qualified Substitute Mortgage
Loan or Loans, the Mortgage Note, the Mortgage, the Assignment in blank or to
the Trustee, and such other documents and agreements, with all necessary
endorsements thereon, as are required by Section 2.01, together with an
Officers' Certificate providing that each such Qualified Substitute Mortgage
Loan satisfies the definition thereof and specifying the Substitution Shortfall
Amount (as described below), if any, in connection with such substitution. The
related Custodian on its behalf and on behalf of the Trustee shall, for the
benefit of the Certificateholders, review each Mortgage File within 90 days
after execution and delivery of this Agreement, to ascertain that all required
documents have been executed, received and recorded, if applicable, and that
such documents relate to the Mortgage Loans. If in the course of such review the
Trustee or the related Custodian on its behalf finds a document or documents
constituting a part of a Mortgage File to be defective in any material respect,
the Trustee or the related Custodian on its behalf shall promptly so notify the
Depositor, the Trust Administrator, the related Originator, the Sponsor and the
Servicer. Monthly Payments due with respect to Qualified Substitute Mortgage
Loans in the month of substitution are not part of the Trust Fund and will be
retained by the related Originator or the Sponsor, as applicable. For the month
of substitution, distributions to Certificateholders will reflect the Monthly
Payment due on such Deleted Mortgage Loan on or before the Due Date in the month
of substitution, and the related Originator or the Sponsor, as applicable, shall
thereafter be entitled to retain all amounts subsequently received in respect of
such Deleted Mortgage Loan. The Trust Administrator shall give or cause to be
given written notice to the Trustee and the Certificateholders that such
substitution has taken place, and the Trust Administrator shall amend or cause
the related Custodian to amend the Mortgage Loan Schedule to reflect the removal
of such Deleted Mortgage Loan from the terms of this Agreement and the
substitution of the Qualified Substitute Mortgage Loan or Loans and, upon
receipt thereof, shall deliver a copy of such amended Mortgage Loan Schedule to
the Servicer. Upon such substitution, such Qualified Substitute Mortgage Loan or
Loans shall constitute part of the Mortgage Pool and shall be subject in all
respects to the terms of this Agreement and the related Assignment Agreement
(including all


                                       58
<PAGE>

applicable representations and warranties thereof included in such Assignment
Agreement), in each case as of the date of substitution.

            For any month in which the related Originator or the Sponsor, as
applicable, substitutes one or more Qualified Substitute Mortgage Loans for one
or more Deleted Mortgage Loans, the Servicer will determine the amount (the
"Substitution Shortfall Amount"), if any, by which the aggregate Purchase Price
of all such Deleted Mortgage Loans exceeds the aggregate of, as to each such
Qualified Substitute Mortgage Loan, the Scheduled Principal Balance thereof as
of the date of substitution, together with one month's interest on such
Scheduled Principal Balance at the applicable Mortgage Loan Remittance Rate. On
the date of such substitution, the Trustee will monitor the obligation of the
related Originator or the Sponsor, as applicable, to deliver or cause to be
delivered, and shall request that such delivery be to the Servicer for deposit
in the Collection Account, an amount equal to the Substitution Shortfall Amount,
if any, and the Trustee (or the related Custodian on behalf of the Trustee, as
applicable), upon receipt of the related Qualified Substitute Mortgage Loan or
Loans and written notice given by the Servicer of such deposit, shall release to
the related Originator or the Sponsor, as applicable, the related Mortgage File
or Files and the Trustee and the Trust Administrator shall execute and deliver
such instruments of transfer or assignment, in each case without recourse, as
the related Originator or the Sponsor, as applicable, shall deliver to it and as
shall be necessary to vest therein any Deleted Mortgage Loan released pursuant
hereto.

            In addition, the related Originator or the Sponsor, as applicable,
shall obtain at its own expense and deliver to the Trustee and the Trust
Administrator an Opinion of Counsel to the effect that such substitution will
not cause (a) any federal tax to be imposed on any Trust REMIC, including
without limitation, any federal tax imposed on "prohibited transactions" under
Section 860F(a)(1) of the Code or on "contributions after the startup date"
under Section 860G(d)(1) of the Code, or (b) any Trust REMIC to fail to qualify
as a REMIC at any time that any Certificate is outstanding.

            In addition, pursuant to the terms of the related Assignment
Agreement, the related Originator or the Seller, as applicable, shall obtain at
its own expense and deliver to the Trustee and the Trust Administrator an
Opinion of Counsel to the effect that such substitution will not cause (a) any
federal tax to be imposed on the Trust Fund, including without limitation, any
federal tax imposed on "prohibited transactions" under Section 860F(a)(I) of the
Code or on "contributions after the startup date" under Section 860G(d)(I) of
the Code or (b) any REMIC to fail to qualify as a REMIC at any time that any
Certificate is outstanding. 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.

             (e)    Upon discovery by the Depositor, the Servicer, the Trust
Administrator 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 to this Agreement, and the Trustee shall give
written notice thereof to the Sponsor. In connection therewith, the related
Originator or the Sponsor, as applicable, pursuant to the related Assignment
Agreement or the Depositor pursuant to this Agreement shall repurchase or,
subject to the limitations set forth in Section 2.03(d), substitute one or more
Qualified Substitute Mortgage Loans for the affected Mortgage


                                        59
<PAGE>

Loan within 90 days of the earlier of discovery or receipt of such notice with
respect to such affected Mortgage Loan. Such repurchase or substitution shall be
made by (i) the related Originator or the Sponsor, as applicable, if the
affected Mortgage Loan's status as a non-qualified mortgage is or results from a
breach of any representation, warranty or covenant made by the related
Originator or the Sponsor, as applicable, under the related Assignment Agreement
or (iii) the Depositor, if the affected Mortgage Loan's status as a
non-qualified mortgage is a breach of no representation or warranty. Any such
repurchase or substitution shall be made in the same manner as set forth in
Sections 2.03(a). The Trustee shall reconvey to the Depositor, the related
Originator or the Sponsor, as the case may be, 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 by the Originator or the Sponsor for breach of
a representation or warranty.

            SECTION 2.04       [Reserved].

            SECTION 2.05       Representations, Warranties and Covenants of the

<PAGE>

            other material agreement or instrument to which the Servicer is a
            party or by which it may be bound, or any statute, order or

            comply with HUD eligibility requirements or that would require
            notification to HUD;

                  (v) The Servicer does not believe, nor does it have any reason
            or cause to believe, that it cannot perform each and every covenant
            made by it and contained in this Agreement;

            obligations hereunder in accordance with the terms hereof;

                  (vii) There are no actions or proceedings against, or

                  (viii) No consent, approval, authorization or order of any
            court or governmental agency or body is required for the execution,

            (x) The Servicer is a member of MERS in good standing, and will
      comply in all material respects with the rules and procedures of MERS in
      connection with the servicing of the Mortgage Loans that are registered
      with MERS.

            It is understood and agreed that the representations, warranties and
covenants set forth in this Section 2.05 shall survive delivery of the Mortgage
Files to the Trustee or to the related Custodian on its behalf and shall inure
to the benefit of the Trustee, the Trust Administrator, the Depositor and the
Certificateholders. Upon discovery by any of the Depositor, the Servicer, the
Trust Administrator or the Trustee of a breach of any of the foregoing
representations, warranties and covenants which materially and adversely affects
the value of any Mortgage Loan or the interests therein of the
Certificateholders, the party discovering such breach shall give prompt written
notice (but in no event later than two Business Days following such discovery)
to the Trustee and the Trust Administrator. Subject to Section 7.01, the
obligation of the Servicer set forth in Section 2.03(c) to cure breaches shall
constitute the sole remedies against the Servicer available to the
Certificateholders, the Depositor, the Trust Administrator or the Trustee on
behalf of the Certificateholders respecting a breach of the representations,
warranties and covenants contained in this Section 2.05.

            SECTION 2.06       Issuance of the Certificates.

            The Trustee acknowledges the assignment to it of the Mortgage Loans
and the delivery to it or to the related Custodian on its behalf of the Mortgage
Files, subject to the provisions of Section 2.01 and Section 2.02, together with
the assignment to it of all other assets included in REMIC I delivered on the
date hereof, receipt of which is hereby acknowledged. Concurrently with such
assignment and delivery of such assets delivered on the date hereof and in
exchange therefor, the Trust Administrator, pursuant to the written request of
the Depositor executed by an officer of the Depositor, has executed,
authenticated and delivered, to or upon the order of the Depositor, the
Certificates in authorized denominations. The interests evidenced by the
Certificates (other than the Class CE Certificates, the Class P Certificates and

constitute the entire beneficial ownership interest in REMIC II.

            SECTION 2.07       Conveyance of the REMIC Regular Interests;
                              Acceptance of the Trust REMICs by the Trustee.

            (a)    The Depositor, concurrently with the execution and delivery

assets described in the definition of REMIC I and declares that it holds and
will hold the same in trust for the exclusive use and benefit of the holders of
the REMIC I Regular Interests and the Class R Certificates (in respect of the

of the Holders of the Regular Certificates (other than the Class CE Certificates
and the Class P Certificates), the Class CE Interest, the Class P Interest and

constitute the entire beneficial ownership interest in REMIC III.

            (d)    The Depositor, concurrently with the execution and delivery
hereof, does hereby transfer, assign, set over and otherwise convey in trust to
the Trustee without recourse all the right, title and interest of the Depositor

                                  ARTICLE III

                          ADMINISTRATION AND SERVICING
                              OF THE MORTGAGE LOANS

            SECTION 3.01       Servicer to Act as Servicer.

            The Servicer shall service and administer the Mortgage Loans on
behalf of the Trustee and in the best interests of and for the benefit of the
Certificateholders (as determined by the Servicer in its reasonable judgment) in
accordance with the terms of this Agreement and the respective Mortgage Loans
and, to the extent consistent with such terms, in the same manner in which it
services and administers similar mortgage loans for its own portfolio, giving
due consideration to customary and usual standards of practice of prudent
mortgage lenders and loan servicers administering similar mortgage loans but
without regard to:

            (i) any relationship that the Servicer, any Sub-Servicer or any
      Affiliate of the Servicer or any Sub-Servicer may have with the related
      Mortgagor;

            (ii) the ownership of any Certificate by the Servicer or any
      Affiliate of the Servicer;

            (iii) the Servicer's obligation to make P&I Advances or Servicing
      Advances; or

            (iv) the Servicer's or any Sub-Servicer's right to receive
      compensation for its services hereunder or with respect to any particular
      transaction.

      To the extent consistent with the foregoing, the Servicer (a) shall seek
the timely and complete recovery of principal and interest on the Mortgage Notes
and (b) shall waive (or permit a Sub-Servicer to waive) a Prepayment Charge only
under the following circumstances: (i) such waiver is standard and customary in
servicing similar Mortgage Loans and such waiver relates to a default or a
reasonably foreseeable default and would, in the reasonable judgment of the
Servicer, maximize recovery of total proceeds taking into account the value of
such Prepayment Charge and the related Mortgage Loan, (ii) the collection of
such Prepayment Charge would be in violation of applicable laws or (iii) the
amount of the Prepayment Charge set forth on the Prepayment Charge Schedule is
not consistent with the related Mortgage Note or is otherwise unenforceable. If
a Prepayment Charge is waived as permitted by meeting the standard described in
clauses (ii) or (iii) above, then, the Trustee shall make commercially
reasonable efforts to attempt to enforce the obligations of the related
Originator under the Master Agreement to pay the amount of such waived
Prepayment Charge, for the benefit of the Holders of the Class P Certificates;
provided, however, that the Trustee shall not be under any obligation to take
any action pursuant to this paragraph unless directed by the Depositor and
provided, further, the Depositor hereby agrees to assist the Trustee in
enforcing any obligations of any Originator to repurchase or substitute for a
Mortgage Loan which has breached a representation or warranty under the related
Assignment Agreement. If the Trustee makes a good faith determination as
evidenced by an officer's certificate delivered by the Trustee to the Trust
Administrator, that the Servicer's efforts are not reasonably expected to be
successful in enforcing such rights, it shall


                                       65
<PAGE>

notify the Trust Administrator of such failure and the Trust Administrator, with
the cooperation of the Servicer, shall enforce the obligation of the related
Originator under the Master Agreement to pay to the Servicer the amount of such
waived Prepayment Charge. If such Originator fails to pay the amount of such
waived Prepayment Charge in accordance with its obligations under the related
Master Agreement, the Trustee, Trust Administrator, the Servicer and the
Depositor shall consult on further actions to be taken against such Originator.
Notwithstanding the foregoing, to the extent that the Trustee and the related
Originator are the same entity, the Trust Administrator shall enforce the
obligations of the related Originator under the related Master Agreement
pursuant to the terms of this paragraph.

            To the extent consistent with the foregoing, the Servicer shall also
seek to maximize the timely and complete recovery of principal and interest on
the Mortgage Notes. Subject only to the above-described servicing standards and
the terms of this Agreement and of the respective Mortgage Loans, the Servicer
shall have full power and authority, acting alone or through Sub-Servicers as
provided in Section 3.02, to do or cause to be done any and all things in
connection with such servicing and administration which it may deem necessary or
desirable. Without limiting the generality of the foregoing, the Servicer in its
own name or in the name of a Sub-Servicer is hereby authorized and empowered by
the Trustee when the Servicer believes it appropriate in its best judgment in
accordance with the servicing standards set forth above, to execute and deliver,
on behalf of the Certificateholders and the Trustee, and upon notice to the
Trustee, any and all instruments of satisfaction or cancellation, or of partial
or full release or discharge, and all other comparable instruments, with respect
to the Mortgage Loans and the Mortgaged Properties and to institute foreclosure
proceedings or obtain a deed-in-lieu of foreclosure so as to convert the
ownership of such properties, and to hold or cause to be held title to such
properties, on behalf of the Trustee and Certificateholders. The Servicer shall
service and administer the Mortgage Loans in accordance with applicable state
and federal law and shall provide to the Mortgagors any reports required to be
provided to them thereby. The Servicer shall also comply in the performance of
this Agreement with all reasonable rules and requirements of any standard hazard
insurance policy. Subject to Section 3.17, the Trustee shall execute, at the
written request of the Servicer, and furnish to the Servicer and any
Sub-Servicer such documents as are necessary or appropriate to enable the
Servicer or any Sub-Servicer to carry out their servicing and administrative
duties hereunder, and the Trustee hereby grants to the Servicer a power of
attorney to carry out such duties. The Trustee shall not be liable for the
actions of the Servicer or any Sub-Servicers under such powers of attorney.

            In accordance with the standards of the preceding paragraph, the
Servicer shall advance or cause to be advanced funds as necessary for the
purpose of effecting the timely payment of taxes and assessments on the
Mortgaged Properties, which advances shall be Servicing Advances reimbursable in
the first instance from related collections from the Mortgagors pursuant to
Section 3.09, and further as provided in Section 3.11. Any cost incurred by the
Servicer or by Sub-Servicers in effecting the timely payment of taxes and
assessments on a Mortgaged Property shall not, for the purpose of calculating
distributions to Certificateholders, be added to the unpaid principal balance of
the related Mortgage Loan, notwithstanding that the terms of such Mortgage Loan
so permit provided, however, that (subject to Section 3.07) the Servicer may
capitalize the amount of any Servicing Advances incurred pursuant to this
Section 3.01 in connection with the modification of a Mortgage Loan.


                                       66
<PAGE>

            The Servicer further is authorized and empowered by the Trustee, on
behalf of the Certificateholders and the Trustee, in its own name or in the name
of the Sub-Servicer, when the Servicer or the Sub-Servicer, as the case may be,
believes it is appropriate in its best judgment to register any Mortgage Loan on
the MERS System, or cause the removal from the registration of any Mortgage Loan
on the MERS System, to execute and deliver, on behalf of the Trustee and the
Certificateholders or any of them, any and all instruments of assignment and
other comparable instruments with respect to such assignment or re-recording of
a Mortgage in the name of MERS, solely as nominee for the Trustee and its
successors and assigns. Any reasonable expenses (i) incurred as a result of MERS
discontinuing or becoming unable to continue operations in connection with the
MERS System or (ii) if the affected Mortgage Loan is in default or, in the
judgment of the Servicer, such default is reasonably foreseeable, incurred in
connection with the actions described in the preceding sentence, shall be
subject to withdrawal by the Servicer from the Collection Account.

            Notwithstanding anything in this Agreement to the contrary, the
Servicer may not make any future advances with respect to a Mortgage Loan
(except as provided in Section 4.03) and the Servicer shall not (i) permit any
modification with respect to any Mortgage Loan (except with respect to a
Mortgage Loan that is in default or, in the judgment of the Servicer, such
default is reasonably foreseeable) that would change the Mortgage Rate, reduce
or increase the principal balance (except for reductions resulting from actual
payments of principal) or change the final maturity date on such Mortgage Loan
or (ii) permit any modification, waiver or amendment of any term of any Mortgage
Loan that would both (A) effect an exchange or reissuance of such Mortgage Loan
under Section 1001 of the Code (or final, temporary or proposed Treasury
regulations promulgated thereunder) and (B) cause any Trust REMIC to fail to
qualify as a REMIC under the Code or the imposition of any tax on "prohibited
transactions" or "contributions after the startup date" under the REMIC
Provisions.

            The Servicer may delegate its responsibilities under this Agreement;
provided, however, that no such delegation shall release the Servicer from the
responsibilities or liabilities arising under this Agreement.

            SECTION 3.02       Sub-Servicing Agreements Between the Servicer and
                              Sub-Servicers.

            (a)    The Servicer may enter into Sub-Servicing Agreements (provided
that such agreements would not result in a withdrawal or a downgrading by the
Rating Agencies of the rating on any Class of Certificates) with Sub-Servicers,
for the servicing and administration of the Mortgage Loans; provided, however,
such sub-servicing arrangement and the terms of the related Sub-Subservicing
Agreement must provide for the servicing of Mortgage Loans in a manner
consistent with the servicing arrangement contemplated hereunder.

            (b)    Each Sub-Servicer shall be (i) authorized to transact business
in the state or states in which the related Mortgaged Properties it is to
service are situated, if and to the extent required by applicable law to enable
the Sub-Servicer to perform its obligations hereunder and under the
Sub-Servicing Agreement and (ii) a Freddie Mac or Fannie Mae approved


                                       67
<PAGE>

mortgage servicer. Each Sub-Servicing Agreement must impose on the Sub-Servicer
requirements conforming to the provisions set forth in Section 3.08 and provide
for servicing of the Mortgage Loans consistent with the terms of this Agreement.
The Servicer will examine each Sub-Servicing Agreement and will be familiar with
the terms thereof. The terms of any Sub-Servicing Agreement will not be
inconsistent with any of the provisions of this Agreement. The Servicer and the
Sub-Servicers may enter into and make amendments to the Sub-Servicing Agreements
or enter into different forms of Sub-Servicing Agreements; provided, however,
that any such amendments or different forms shall be consistent with and not
violate the provisions of this Agreement, and that no such amendment or
different form shall be made or entered into which could be reasonably expected
to be materially adverse to the interests of the Certificateholders, without the
consent of the Holders of Certificates entitled to at least 66% of the Voting
Rights. Any variation without the consent of the Holders of Certificates
entitled to at least 66% of the Voting Rights from the provisions set forth in
Section 3.08 relating to insurance or priority requirements of Sub-Servicing
Accounts, or credits and charges to the Sub- Servicing Accounts or the timing
and amount of remittances by the Sub-Servicers to the Servicer, are conclusively
deemed to be inconsistent with this Agreement and therefore prohibited. The
Servicer shall deliver to the Trustee and the Trust Administrator copies of all
Sub-Servicing Agreements, and any amendments or modifications thereof, promptly
upon the Servicer's execution and delivery of such instruments.

            (c)    As part of its servicing activities hereunder, the Servicer
(except as otherwise provided in the last sentence of this paragraph), for the
benefit of the Trustee and the Certificateholders, shall enforce the obligations
of each Sub-Servicer under the related Sub-Servicing Agreement, including,
without limitation, any obligation to make advances in respect of delinquent
payments as required by a Sub-Servicing Agreement. Such enforcement, including,
without limitation, the legal prosecution of claims, termination of
Sub-Servicing Agreements, and the pursuit of other appropriate remedies, shall
be in such form and carried out to such an extent and at such time as the
Servicer, in its good faith business judgment, would require were it the owner
of the related Mortgage Loans. The Servicer shall pay the costs of such
enforcement at its own expense, and shall be reimbursed therefor only (i) from a
general recovery resulting from such enforcement, to the extent, if any, that
such recovery exceeds all amounts due in respect of the related Mortgage Loans,
or (ii) from a specific recovery of costs, expenses or attorneys' fees against
the party against whom such enforcement is directed.

            SECTION 3.03       Successor Sub-Servicers.

            The Servicer shall be entitled to terminate any Sub-Servicing
Agreement and the rights and obligations of any Sub-Servicer pursuant to any
Sub-Servicing Agreement in accordance with the terms and conditions of such
Sub-Servicing Agreement. In the event of termination of any Sub-Servicer, all
servicing obligations of such Sub-Servicer shall be assumed simultaneously by
the Servicer without any act or deed on the part of such Sub-Servicer or the
Servicer, and the Servicer either shall service directly the related Mortgage
Loans or shall enter into a Sub-Servicing Agreement with a successor
Sub-Servicer which qualifies under Section 3.02.

            Any Sub-Servicing Agreement shall include the provision that such
agreement may be immediately terminated by the Trustee or the Trust
Administrator without fee, in


                                       68
<PAGE>

accordance with the terms of this Agreement, in the event that the Servicer
shall, for any reason, no longer be the Servicer (including termination due to a
Servicer Event of Default).

            SECTION 3.04       Liability of the Servicer.

            Notwithstanding any Sub-Servicing Agreement, any of the provisions
of this Agreement relating to agreements or arrangements between the Servicer
and a Sub-Servicer or reference to actions taken through a Sub-Servicer or
otherwise, the Servicer shall remain obligated and primarily liable to the
Trustee and the Certificateholders for the servicing and administering of the
Mortgage Loans in accordance with the provisions of Section 3.01 without
diminution of such obligation or liability by virtue of such Sub-Servicing
Agreements or arrangements or by virtue of indemnification from the Sub-Servicer
and to the same extent and under the same terms and conditions as if the
Servicer alone were servicing and administering the Mortgage Loans. The Servicer
shall be entitled to enter into any agreement with a Sub- Servicer for
indemnification of the Servicer by such Sub-Servicer and nothing contained in
this Agreement shall be deemed to limit or modify such indemnification.

            SECTION 3.05       No Contractual Relationship Between Sub-Servicers
                              and Trustee, Trust Administrator or
                              Certificateholders.

            Any Sub-Servicing Agreement that may be entered into and any
transactions or services relating to the Mortgage Loans involving a Sub-Servicer
in its capacity as such shall be deemed to be between the Sub-Servicer and the
Servicer alone, and the Trustee, the Trust Administrator and the
Certificateholders shall not be deemed parties thereto and shall have no claims,
rights, obligations, duties or liabilities with respect to the Sub-Servicer
except as set forth in Section 3.06. The Servicer shall be solely liable for all
fees owed by it to any Sub-Servicer, irrespective of whether the Servicer's
compensation pursuant to this Agreement is sufficient to pay such fees.

            SECTION 3.06        Assumption or Termination of Sub-Servicing
                              Agreements by Trust Administrator.

            In the event the Servicer shall for any reason no longer be the
servicer (including by reason of the occurrence of a Servicer Event of Default),
the Trust Administrator or its designee shall thereupon assume all of the rights
and obligations of the Servicer under each Sub-Servicing Agreement that the
Servicer may have entered into, unless the Trust Administrator elects to
terminate any Sub-Servicing Agreement in accordance with its terms as provided
in Section 3.03. Upon such assumption, the Trust Administrator, its designee or
the successor servicer for the Trust Administrator appointed pursuant to Section
7.02 shall be deemed, subject to Section 3.03, to have assumed all of the
Servicer's interest therein and to have replaced the Servicer as a party to each
Sub-Servicing Agreement to the same extent as if each Sub-Servicing Agreement
had been assigned to the assuming party, except that (i) the Servicer shall not
thereby be relieved of any liability or obligations under any Sub-Servicing
Agreement and (ii) none of the Trust Administrator, its designee or any
successor Servicer shall be deemed to have assumed any liability or obligation
of the Servicer that arose before it ceased to be the Servicer.


                                       69
<PAGE>

            The Servicer at its expense shall, upon request of the Trust
Administrator, deliver to the assuming party all documents and records relating
to each Sub-Servicing Agreement and the Mortgage Loans then being serviced and
an accounting of amounts collected and held by or on behalf of it, and otherwise
use its best efforts to effect the orderly and efficient transfer of the Sub-
Servicing Agreements to the assuming party.

            SECTION 3.07       Collection of Certain Mortgage Loan Payments.

            The Servicer shall make reasonable efforts to collect all payments
called for under the terms and provisions of the Mortgage Loans, and shall, to
the extent such procedures shall be consistent with this Agreement and the terms
and provisions of any applicable insurance policies, follow such collection
procedures as it would follow with respect to mortgage loans comparable to the
Mortgage Loans and held for its own account. Consistent with the foregoing and
the servicing standards set forth in Section 3.01, the Servicer may in its
discretion (i) waive any late payment charge or, if applicable, penalty interest
or (ii) extend the due dates for Monthly Payments due on a Mortgage Note for a
period of not greater than 180 days; provided that any extension pursuant to
clause (ii) above shall not affect the amortization schedule of any Mortgage
Loan for purposes of any computation hereunder, except as provided below. In the
event of any such arrangement pursuant to clause (ii) above, the Servicer shall
make timely advances on such Mortgage Loan during such extension pursuant to
Section 4.03 and in accordance with the amortization schedule of such Mortgage
Loan without modification thereof by reason of such arrangements.
Notwithstanding the foregoing, in the event that any Mortgage Loan is in default
or, in the judgment of the Servicer, such default is reasonably foreseeable, the
Servicer, consistent with the standards set forth in Section 3.01, may waive,
modify or vary any term of such Mortgage Loan (including modifications that
change the Mortgage Rate, forgive the payment of principal or interest or extend
the final maturity date of such Mortgage Loan), accept payment from the related
Mortgagor of an amount less than the Stated Principal Balance in final
satisfaction of such Mortgage Loan (such payment, a "Short Pay-off") or consent
to the postponement of strict compliance with any such term or otherwise grant
indulgence to any Mortgagor, if in the Servicer's determination such waiver,
modification, postponement or indulgence is not materially adverse to the
interests of the Certificateholders (taking into account any estimated Realized
Loss that might result absent such action); provided, however, the Servicer
shall not modify any Mortgage Loan in a manner that would capitalize the amount
of any unpaid Monthly Payments or tax or insurance payments advanced by the
Servicer on the Mortgagor's behalf unless the related Mortgagor shall have
remitted an amount equal to a full Monthly Payment (or, in the case of any
Mortgage Loan subject to a forbearance plan or bankruptcy plan, a full modified
monthly payment under such plan) in each of the three calendar months
immediately preceding the month of such modification.

            SECTION 3.08       Sub-Servicing Accounts.

            In those cases where a Sub-Servicer is servicing a Mortgage Loan
pursuant to a Sub-Servicing Agreement, the Sub-Servicer will be required to
establish and maintain one or more accounts (collectively, the "Sub-Servicing
Account"). The Sub-Servicing Account shall be an Eligible Account and shall
comply with all requirements of this Agreement relating to the Collection
Account. The Sub-Servicer shall deposit in the Sub-Servicing Account, in no
event more than two Business Days after the Sub-Servicer's receipt thereof, all
proceeds of Mortgage


                                       70
<PAGE>

Loans received by the Sub-Servicer less its servicing compensation to the extent
permitted by the Sub-Servicing Agreement. The Sub-Servicer shall thereafter
remit such proceeds to the Servicer for deposit in the Collection Account not
later than two Business Days after the deposit of such amounts in the
Sub-Servicing Account. For purposes of this Agreement, the Servicer shall be
deemed to have received payments on the Mortgage Loans when the Sub-Servicer
receives such payments.

            SECTION 3.09       Collection of Taxes, Assessments and Similar
                              Items; Servicing Accounts.

            To the extent the terms of a Mortgage provide for Escrow Payments,
the Servicer shall establish and maintain one or more accounts (the "Servicing
Accounts"), into which all collections from the Mortgagors (or related advances
from Sub-Servicers) for the payment of taxes, assessments, fire, flood, and
hazard insurance premiums, hazard insurance proceeds (to the extent such amounts
are to be applied to the restoration or repair of the property) and comparable
items for the account of the Mortgagors ("Escrow Payments") shall be deposited
and retained. Servicing Accounts shall be Eligible Accounts. The Servicer shall
deposit in the Servicing Accounts on a daily basis and in no event later than
the second Business Day after receipt, and retain therein, all Escrow Payments
collected on account of the Mortgage Loans, for the purpose of effecting the
timely payment of any such items as required under the terms of this Agreement.
Withdrawals of amounts from a Servicing Account may be made only to (i) effect
timely payment of taxes, assessments, fire, flood, and hazard insurance
premiums, and comparable items; (ii) reimburse the Servicer out of related
collections for any advances made pursuant to Section 3.01 (with respect to
taxes and assessments) and Section 3.14 (with respect to fire, flood and hazard
insurance); (iii) refund to Mortgagors any sums as may be determined to be
overages; (iv) pay interest, if required and as described below, to Mortgagors
on balances in the Servicing Account; or (v) clear and terminate the Servicing
Account at the termination of the Servicer's obligations and responsibilities in
respect of the Mortgage Loans under this Agreement in accordance with Article
IX. As part of its servicing duties, the Servicer shall pay to the Mortgagors
interest on funds in Servicing Accounts, to the extent required by law and, to
the extent that interest earned on funds in the Servicing Accounts is
insufficient, to pay such interest from its or their own funds, without any
reimbursement therefor. Notwithstanding the foregoing, the Servicer shall not be
obligated to collect Escrow Payments if the related Mortgage Loan does not
require such payments but the Servicer shall nevertheless be obligated to make
Servicing Advances as provided in Section 3.01. In the event the Servicer shall
deposit in the Servicing Accounts any amount not required to be deposited
therein, it may at any time withdraw such amount from the Servicing Accounts,
any provision to the contrary notwithstanding.

            To the extent that a Mortgage does not provide for Escrow Payments,
the Servicer (i) shall determine whether any such payments are made by the
Mortgagor in a manner and at a time that is necessary to avoid the loss of the
Mortgaged Property due to a tax sale or the foreclosure as a result of a tax
lien and (ii) shall ensure that all insurance required to be maintained on the
Mortgaged Property pursuant to this Agreement is maintained. If any such payment
has not been made and the Servicer receives notice of a tax lien with respect to
the Mortgage Loan being imposed, the Servicer will, to the extent required to
avoid loss of the Mortgaged Property, advance or cause to be advanced funds
necessary to discharge such lien on the Mortgaged Property. The Servicer assumes
full responsibility for the payment of all such


                                       71
<PAGE>

bills and shall effect payments of all such bills irrespective of the
Mortgagor's faithful performance in the payment of same or the making of the
Escrow Payments and shall make Servicing Advances from its own funds to effect
such payments.

            SECTION 3.10       Collection Account and Distribution Account.

            (a)    On behalf of the Trust Fund, the Servicer shall establish and
maintain one or more separate, segregated trust accounts (such account or
accounts, the "Collection Account"), held in trust for the benefit of the Trust
Administrator, the Trustee and the Certificateholders. On behalf of the Trust
Fund, the Servicer shall deposit or cause to be deposited in the clearing
account (which account must be an Eligible Account) in which it customarily
deposits payments and collections on mortgage loans in connection with its
mortgage loan servicing activities on a daily basis, and in no event more than
two Business Days after the Servicer's receipt thereof, and shall thereafter
deposit in the Collection Account, in no event more than one Business Day after
the deposit of such funds into the clearing account, as and when received or as
otherwise required hereunder, the following payments and collections received or
made by it from and after the Cut-off Date (other than in respect of principal
or interest on the related Mortgage Loans due on or before the Cut-off Date), or
payments (other than Principal Prepayments) received by it on or prior to the
Cut-off Date but allocable to a Due Period subsequent thereto:

            (i) all payments on account of principal, including Principal
      Prepayments (but not Prepayment Charges), on the Mortgage Loans;

            (ii) all payments on account of interest (the related Servicing Fee)
      on each Mortgage Loan;

            (iii) all Insurance Proceeds and Liquidation Proceeds (other than
      proceeds collected in respect of any particular REO Property and amounts
      paid by the Servicer in connection with a purchase of Mortgage Loans and
      REO Properties pursuant to Section 9.01);

            (iv) any amounts required to be deposited pursuant to Section 3.12
      in connection with any losses realized on Permitted Investments with
      respect to funds held in the Collection Account;

            (v) any amounts required to be deposited by the Servicer pursuant to
       the second paragraph of Section 3.14(a) in respect of any blanket policy
      deductibles;

            (vi) all proceeds of any Mortgage Loan repurchased or purchased in
      accordance with Section 2.03 or Section 9.01;

            (vii) all amounts required to be deposited in connection with
      shortfalls in principal amount of Qualified Substitute Mortgage Loans
      pursuant to Section 2.03; and

            (viii) all Prepayment Charges collected by the Servicer and any
      Servicer Prepayment Charge Payment Amounts in connection with the
      Principal Prepayment of any of the Mortgage Loans.


                                       72
<PAGE>

            For purposes of the immediately preceding sentence, the Cut-off Date
with respect to any Qualified Substitute Mortgage Loan shall be deemed to be the
date of substitution.

            The foregoing requirements for deposit in the Collection Accounts
shall be exclusive, it being understood and agreed that, without limiting the
generality of the foregoing, payments in the nature of late payment charges or
assumption fees (other than Prepayment Charges) need not be deposited by the
Servicer in the Collection Account. In the event the Servicer shall deposit in
the Collection Account any amount not required to be deposited therein, it may
at any time withdraw such amount from the Collection Account, any provision
herein to the contrary notwithstanding.

            (b)    On behalf of the Trust Fund, the Trust Administrator, as agent
for the Trustee, shall establish and maintain one or more separate, segregated
trust accounts (such account or accounts, the "Distribution Account"), held in
trust for the benefit of the Certificateholders. On behalf of the Trust Fund,
the Servicer shall deliver to the Trust Administrator in immediately available
funds for deposit in the Distribution Account on or before 4:00 p.m. New York
time (i) on the Servicer Remittance Date, that portion of the Available
Distribution Amount (calculated without regard to the subtraction therefrom of
the Credit Risk Manager Fee) for the related Distribution Date then on deposit
in the Collection Account, the amount of all Prepayment Charges collected during
the applicable Prepayment Period by the Servicer and Servicer Prepayment Charge
Payment Amounts in connection with the Principal Prepayment of any of the
Mortgage Loans then on deposit in the Collection Account and (ii) on each
Business Day as of the commencement of which the balance on deposit in the
Collection Account exceeds $75,000 following any withdrawals pursuant to the
next succeeding sentence, the amount of such excess, but only if the Collection
Account constitutes an Eligible Account solely pursuant to clause (ii) of the
definition of "Eligible Account." If the balance on deposit in the Collection
Account exceeds $75,000 as of the commencement of business on any Business Day
and the Collection Account constitutes an Eligible Account solely pursuant to
clause (ii) of the definition of "Eligible Account," the Servicer shall, on or
before 4:00 p.m. New York time on such Business Day, withdraw from the
Collection Account any and all amounts payable or reimbursable to the Depositor,
the Servicer, the Trustee, the Trust Administrator, the Sponsor or any
Sub-Servicer pursuant to Section 3.11 and shall pay such amounts to the Persons
entitled thereto.

            (c)    Funds in the Collection Account and the Distribution Account
may be invested in Permitted Investments in accordance with the provisions set
forth in Section 3.12. The Servicer shall give notice to the Trustee, the Trust
Administrator and the Depositor of the location of the Collection Account
maintained by it when established and prior to any change thereof. The Trust
Administrator shall give notice to the Servicer, the Trustee and the Depositor
of the location of the Distribution Account when established and prior to any
change thereof.

            (d)    Funds held in the Collection Account at any time may be
delivered by the Servicer to the Trust Administrator for deposit in an account
(which may be the Distribution Account and must satisfy the standards for the
Distribution Account as set forth in the definition thereof) and for all
purposes of this Agreement shall be deemed to be a part of the Collection
Account; provided, however, that the Trust Administrator shall have the sole
authority to withdraw any funds held pursuant to this subsection (d). In the
event the Servicer shall deliver to


                                       73
<PAGE>

the Trust Administrator for deposit in the Distribution Account any amount not
required to be deposited therein, it may at any time request that the Trust
Administrator withdraw such amount from the Distribution Account and remit to it
any such amount, any provision herein to the contrary notwithstanding. In
addition, the Servicer shall deliver to the Trust Administrator from time to
time for deposit, and upon written notification from the Servicer, the Trust
Administrator shall so deposit, in the Distribution Account:

             (i) any P&I Advances, as required pursuant to Section 4.03;

            (ii) any amounts required to be deposited pursuant to Section
      3.23(d) or (f) in connection with any REO Property;

            (iii) any amounts to be paid by the Servicer in connection with a
      purchase of Mortgage Loans and REO Properties pursuant to Section 9.01;

            (iv) any amounts required to be deposited pursuant to Section 3.24
      in connection with any Prepayment Interest Shortfalls; and

             (v) any Stayed Funds, as soon as permitted by the federal bankruptcy
      court having jurisdiction in such matters.

            (e)    Promptly upon receipt of any Stayed Funds, whether from the
Servicer, a trustee in bankruptcy, or federal bankruptcy court or other source,
the Trust Administrator shall deposit such funds in the Distribution Account,
subject to withdrawal thereof as permitted hereunder.

            (f)    The Servicer shall deposit in the Collection Account any
amounts required to be deposited pursuant to Section 3.12(b) in connection with
losses realized on Permitted Investments with respect to funds held in the
Collection Account.

            SECTION 3.11       Withdrawals from the Collection Account and
                               Distribution Account.

            (a) The Servicer shall, from time to time, make withdrawals from the
Collection Account for any of the following purposes or as described in Section
4.03:

            (i) to remit to the Trust Administrator for deposit in the
      Distribution Account the amounts required to be so remitted pursuant to
      Section 3.10(b) or permitted to be so remitted pursuant to the first
      sentence of Section 3.10(d);

            (ii) subject to Section 3.16(d), to reimburse the Servicer for P&I
      Advances, but only to the extent of amounts received which represent Late
      Collections (net of the related Servicing Fees) of Monthly Payments on
      Mortgage Loans with respect to which such P&I Advances were made in
       accordance with the provisions of Section 4.03;

            (iii) subject to Section 3.16(d), to pay the Servicer or any
      Sub-Servicer (A) any unpaid Servicing Fees, (B) any unreimbursed Servicing
      Advances with respect to each Mortgage Loan, but only to the extent of any
      Liquidation Proceeds, Insurance Proceeds


                                       74
<PAGE>

      or other amounts as may be collected by the Servicer from a Mortgagor, or
      otherwise received with respect to such Mortgage Loan and (C) without
      limiting any right of withdrawal set forth in clause (vi) below, any
      Servicing Advances made with respect to a Mortgage Loan that, following
      the final liquidation of a Mortgage Loan are Nonrecoverable Advances, but
      only to the extent that Late Collections, Liquidation Proceeds and
      Insurance Proceeds received with respect to such Mortgage Loan are
      insufficient to reimburse the Servicer or any Sub-Servicer for such
      Servicing Advances;

             (iv) to pay to the Servicer as servicing compensation (in addition
      to the Servicing Fee) on the Servicer Remittance Date any interest or
      investment income earned on funds deposited in the Collection Account;

            (v) to pay to the Servicer, the Depositor or the Sponsor, as the
      case may be, with respect to each Mortgage Loan that has previously been
      purchased or replaced pursuant to Section 2.03 all amounts received
      thereon subsequent to the date of purchase or substitution, as the case
      may be;

            (vi) to reimburse the Servicer for any P&I Advance or Servicing
      Advance previously made which the Servicer has determined to be a
      Nonrecoverable Advance in accordance with the provisions of Section 4.03;

            (vii) to reimburse the Servicer or the Depositor for expenses
      incurred by or reimbursable to the Servicer or the Depositor, as the case
      may be, pursuant to Section 6.03;

            (viii) to reimburse the Servicer, the Trust Administrator or the
      Trustee, as the case may be, for expenses reasonably incurred in respect
      of the breach or defect giving rise to the purchase obligation under
      Section 2.03 or Section 2.04 of this Agreement that were included in the
      Purchase Price of the Mortgage Loan, including any expenses arising out of
      the enforcement of the purchase obligation;

            (ix) [reserved];

            (x) to pay, or to reimburse the Servicer for advances in respect of
      expenses incurred in connection with any Mortgage Loan pursuant to Section
      3.16(b); and

            (xi) to clear and terminate the Collection Account pursuant to
      Section 9.01.

            The Servicer shall keep and maintain separate accounting, on a
Mortgage Loan by Mortgage Loan basis, for the purpose of justifying any
withdrawal from the Collection Account, to the extent held by or on behalf of
it, pursuant to subclauses (ii), (iii), (iv), (v), (vi), (viii) and (ix) above.
The Servicer shall provide written notification to the Trustee and the Trust
Administrator, on or prior to the next succeeding Servicer Remittance Date, upon
making any withdrawals from the Collection Account pursuant to subclause (vii)
above.

            (b) The Trust Administrator shall, from time to time, make
withdrawals from the Distribution Account, for any of the following purposes,
without priority:


                                       75
<PAGE>

            (i) to make distributions to the Cap Account in accordance with
      Section 4.08;

            (ii) to make distributions to Certificateholders in accordance with
      Section 4.01;

            (iii) to pay to itself any interest income earned on funds deposited
      in the Distribution Account pursuant to Section 3.12(c);

            (iv) to reimburse the Trust Administrator or the Trustee pursuant to
      Section 7.02;

            (v) to pay any amounts in respect of taxes pursuant to
      10.01(g)(iii);

            (vi) to pay any Extraordinary Trust Fund Expenses;

            (vii) to reimburse the Trust Administrator or the Trustee for any
      P&I Advance made by it under Section 7.01 (if not reimbursed by the
      Servicer) to the same extent the Servicer would be entitled to
      reimbursement under Section 3.11(a);

            (viii) to pay the Credit Risk Manager the Credit Risk Manager Fee;
      and

            (ix) to clear and terminate the Distribution Account pursuant to
      Section 9.01.

            SECTION 3.12       Investment of Funds in the Collection Account and
                              the Distribution Account.

            (a) The Servicer may direct any depository institution maintaining
the Collection Account (for purposes of this Section 3.12, an "Investment
Account"), and the Trust Administrator may at the direction of the Depositor
direct any depository institution maintaining the Distribution Account (for
purposes of this Section 3.12, also an "Investment Account"), to hold the funds
in such Investment Account uninvested or to invest the funds in such Investment
Account in one or more Permitted Investments specified in such instruction
bearing interest or sold at a discount, and maturing, unless payable on demand,
(i) no later than the Business Day immediately preceding the date on which such
funds are required to be withdrawn from such account pursuant to this Agreement,
if a Person other than the Trust Administrator is the obligor thereon, and (ii)
no later than the date on which such funds are required to be withdrawn from
such account pursuant to this Agreement, if the Trust Administrator is the
obligor thereon. All such Permitted Investments shall be held to maturity,
unless payable on demand. Any investment of funds in an Investment Account shall
be made in the name of the Trust Administrator (in its capacity as such) or in
the name of a nominee of the Trust Administrator. The Trust Administrator shall
be entitled to sole possession (except with respect to investment direction of
funds held in the Collection Account and the Distribution Account and any income
and gain realized thereon) over each such investment, and any certificate or
other instrument evidencing any such investment shall be delivered directly to
the Trust Administrator or its agent, together with any document of transfer
necessary to transfer title to such investment to the Trust Administrator or its
nominee. In the event amounts on deposit in an Investment Account are at any
time invested in a Permitted Investment payable on demand, the Trust
Administrator shall:


                                       76
<PAGE>

            (x) consistent with any notice required to be given thereunder,
      demand that payment thereon be made on the last day such Permitted
      Investment may otherwise mature hereunder in an amount equal to the lesser
      of (1) all amounts then payable thereunder and (2) the amount required to
      be withdrawn on such date; and

            (y) demand payment of all amounts due thereunder promptly upon
      determination by a Responsible Officer of the Trust Administrator that
      such Permitted Investment would not constitute a Permitted Investment in
      respect of funds thereafter on deposit in the Investment Account.

            (b) All income and gain realized from the investment of funds
deposited in the Collection Account held by or on behalf of the Servicer, shall
be for the benefit of the Servicer and shall be subject to its withdrawal in
accordance with Section 3.11. The Servicer shall deposit in the Collection
Account the amount of any loss of principal incurred in respect of any such
Permitted Investment made with funds in such accounts immediately upon
realization of such loss.

            (c) All income and gain realized from the investment of funds
deposited in the Distribution Account held by or on behalf of the Trust
Administrator, shall be for the benefit of the Trust Administrator and shall be
subject to its withdrawal at any time. The Trust Administrator shall deposit in
the Distribution Account the amount of any loss of principal incurred in respect
of any such Permitted Investment made with funds in such accounts immediately
upon realization of such loss.

            (d) Except as otherwise expressly provided in this Agreement, if any
default occurs in the making of a payment due under any Permitted Investment, or
if a default occurs in any other performance required under any Permitted
Investment, the Trust Administrator may and, subject to Section 8.01 and Section
8.02(a)(v), upon the request of the Holders of Certificates representing more
than 50% of the Voting Rights allocated to any Class of Certificates, shall take
such action as may be appropriate to enforce such payment or performance,
including the institution and prosecution of appropriate proceedings.

            SECTION 3.13       [Reserved].

            SECTION 3.14       Maintenance of Hazard Insurance and Errors and
                              Omissions and Fidelity Coverage.

            (a) The terms of each Mortgage Note require the related Mortgagor to
maintain fire, flood and hazard insurance policies. To the extent such policies
are not maintained, the Servicer shall cause to be maintained for each Mortgaged
Property fire and hazard insurance with extended coverage as is customary in the
area where the Mortgaged Property is located in an amount which is at least
equal to the lesser of the current principal balance of such Mortgage Loan and
the amount necessary to fully compensate for any damage or loss to the
improvements which are a part of such property on a replacement cost basis, in
each case in an amount not less than such amount as is necessary to avoid the
application of any coinsurance clause contained in the related hazard insurance
policy. The Servicer shall also cause to be maintained fire and hazard insurance
on each REO Property with extended coverage as is customary in the area


                                       77
<PAGE>

where the Mortgaged Property is located in an amount which is at least equal to
the lesser of (i) the maximum insurable value of the improvements which are a
part of such property and (ii) the outstanding principal balance of the related
Mortgage Loan at the time it became an REO Property. The Servicer will comply in
the performance of this Agreement with all reasonable rules and requirements of
each insurer under any such hazard policies. Any amounts to be collected by the
Servicer under any such policies (other than amounts to be applied to the
restoration or repair of the property subject to the related Mortgage or amounts
to be released to the Mortgagor in accordance with the procedures that the
Servicer would follow in servicing loans held for its own account, subject to
the terms and conditions of the related Mortgage and Mortgage Note) shall be
deposited in the Collection Account, subject to withdrawal pursuant to Section
3.11, if received in respect of a Mortgage Loan, or in the REO Account, subject
to withdrawal pursuant to Section 3.23, if received in respect of an REO
Property. Any cost incurred by the Servicer in maintaining any such insurance
shall not, for the purpose of calculating distributions to Certificateholders,
be added to the unpaid principal balance of the related Mortgage Loan,
notwithstanding that the terms of such Mortgage Loan so permit; provided,
however, that the Servicer may capitalize the amount of any Servicing Advances
incurred pursuant to this Section 3.14 in connection with the modification of a
Mortgage Loan. It is understood and agreed that no earthquake or other
additional insurance is to be required of any Mortgagor other than pursuant to
such applicable laws and regulations as shall at any time be in force and as
shall require such additional insurance. If the Mortgaged Property or REO
Property is at any time in an area identified in the Federal Register by the
Federal Emergency Management Agency as having special flood hazards, the
Servicer will cause to be maintained a flood insurance policy in respect
thereof. Such flood insurance shall be in an amount equal to the lesser of (i)
the unpaid principal balance of the related Mortgage Loan and (ii) the maximum
amount of such insurance available for the related Mortgaged Property under the
national flood insurance program (assuming that the area in which such Mortgaged
Property is located is participating in such program).

            In the event that the Servicer shall obtain and maintain a blanket
policy with an insurer having a General Policy Rating of B:VI or better in
Best's Key Rating Guide insuring against hazard losses on all of the Mortgage
Loans, it shall conclusively be deemed to have satisfied its obligations as set
forth in the first two sentences of this Section 3.14, it being understood and
agreed that such policy may contain a deductible clause, in which case the
Servicer shall, in the event that there shall not have been maintained on the
related Mortgaged Property or REO Property a policy complying with the first two
sentences of this Section 3.14, and there shall have been one or more losses
which would have been covered by such policy, deposit to the Collection Account
from its own funds the amount not otherwise payable under the blanket policy
because of such deductible clause. In connection with its activities as
administrator and servicer of the Mortgage Loans, the Servicer agrees to prepare
and present, on behalf of itself, the Trustee, the Trust Fund and the
Certificateholders, claims under any such blanket policy in a timely fashion in
accordance with the terms of such policy.

             (b) The Servicer shall keep in force during the term of this
Agreement a policy or policies of insurance covering errors and omissions for
failure in the performance of its respective obligations under this Agreement,
which policy or policies shall be in such form and amount that would meet the
requirements of Fannie Mae or Freddie Mac if it were the purchaser of the
Mortgage Loans, unless the Servicer, has obtained a waiver of such requirements
from Fannie Mae or Freddie Mac. The Servicer shall each also maintain a fidelity
bond in the form and amount that would meet the requirements of Fannie Mae or
Freddie Mac, unless the Servicer, has obtained a waiver of such requirements
from


                                       78
<PAGE>

Fannie Mae or Freddie Mac. The Servicer shall be deemed to have complied with
this provision if an Affiliate of the Servicer, has such errors and omissions
and fidelity bond coverage and, by the terms of such insurance policy or
fidelity bond, the coverage afforded thereunder extends to the Servicer. Any
such errors and omissions policy and fidelity bond shall by its terms not be
cancelable without thirty days' prior written notice to the Trustee and the
Trust Administrator.

            SECTION 3.15       Enforcement of Due-On-Sale Clauses; Assumption
                              Agreements.

            The Servicer will, to the extent it has knowledge of any conveyance
or prospective conveyance of any Mortgaged Property by any Mortgagor (whether by
absolute conveyance or by contract of sale, and whether or not the Mortgagor
remains or is to remain liable under the Mortgage Note and/or the Mortgage),
exercise its rights to accelerate the maturity of such Mortgage Loan under the
"due-on-sale" clause, if any, applicable thereto; provided, however, that the
Servicer shall not exercise any such rights if prohibited by law from doing so.
If the Servicer reasonably believes it is unable under applicable law to enforce
such "due-on-sale" clause, or if any of the other conditions set forth in the
proviso to the preceding sentence apply, the Servicer will enter into an
assumption and modification agreement from or with the person to whom such
property has been conveyed or is proposed to be conveyed, pursuant to which such
person becomes liable under the Mortgage Note and, to the extent permitted by
applicable state law, the Mortgagor remains liable thereon. The Servicer is also
authorized to enter into a substitution of liability agreement with such person,
pursuant to which the original Mortgagor is released from liability and such
person is substituted as the Mortgagor and becomes liable under the Mortgage
Note, provided that no such substitution shall be effective unless such person
satisfies the then current underwriting criteria of the Servicer for mortgage
loans similar to the Mortgage Loans. In connection with any assumption or
substitution, the Servicer shall apply such underwriting standards and follow
such practices and procedures as shall be normal and usual in its general
mortgage servicing activities and as it applies to other mortgage loans owned
solely by it. The Servicer shall not take or enter into any assumption and
modification agreement, however, unless (to the extent practicable in the
circumstances) it shall have received confirmation, in writing, of the continued
effectiveness of any applicable hazard insurance policy. Any fee collected by
the Servicer in respect of an assumption or substitution of liability agreement
will be retained by the Servicer as additional servicing compensation. In
connection with any such assumption, no material term of the Mortgage Note
(including but not limited to the related Mortgage Rate and the amount of the
Monthly Payment) may be amended or modified, except as otherwise required
pursuant to the terms thereof. The Servicer shall notify the Trustee and the
Trust Administrator that any such substitution or assumption agreement has been
completed by forwarding to the Trust Administrator on behalf of the Trustee the
executed original of such substitution or assumption agreement, which document
shall be added to the related Mortgage File and shall, for all purposes, be
considered a part of such Mortgage File to the same extent as all other
documents and instruments constituting a part thereof.


                                       79
<PAGE>

            Notwithstanding the foregoing paragraph or any other provision of
this Agreement, the Servicer shall not be deemed to be in default, breach or any
other violation of its obligations hereunder by reason of any assumption of a
Mortgage Loan by operation of law or by the terms of the Mortgage Note or any
assumption which the Servicer may be restricted by law from preventing, for any
reason whatever. For purposes of this Section 3.15, the term "assumption" is
deemed to also include a sale (of the Mortgaged Property) subject to the
Mortgage that is not accompanied by an assumption or substitution of liability
agreement.

            SECTION 3.16       Realization Upon Defaulted Mortgage Loans.

             (a) The Servicer shall, consistent with the servicing standard set
forth in Section 3.01, foreclose upon or otherwise comparably convert the
ownership of properties securing such of the Mortgage Loans as come into and
continue in default and as to which no satisfactory arrangements can be made for
collection of delinquent payments pursuant to Section 3.07. The Servicer shall
be responsible for all costs and expenses incurred by it in any such
proceedings; provided, however, that such costs and expenses will be recoverable
as Servicing Advances by the Servicer as contemplated in Section 3.11 and
Section 3.23. The foregoing is subject to the provision that, in any case in
which Mortgaged Property shall have suffered damage from an Uninsured Cause, the
Servicer shall not be required to expend its own funds toward the restoration of
such property unless it shall determine in its discretion that such restoration
will increase the proceeds of liquidation of the related Mortgage Loan after
reimbursement to itself for such expenses.

            (b) Notwithstanding the foregoing provisions of this Section 3.16 or
any other provision of this Agreement, with respect to any Mortgage Loan as to
which the Servicer has received actual notice of, or has actual knowledge of,
the presence of any toxic or hazardous substance on the related Mortgaged
Property, the Servicer shall not, on behalf of the Trustee, either (i) obtain
title to such Mortgaged Property as a result of or in lieu of foreclosure or
otherwise, or (ii) otherwise acquire possession of, or take any other action
with respect to, such Mortgaged Property, if, as a result of any such action,
the Trustee, the Trust Fund, the Trust Administrator, the Servicer or the
Certificateholders would be considered to hold title to, to be a
"mortgagee-in-possession" of, or to be an "owner" or "operator" of such
Mortgaged Property within the meaning of the Comprehensive Environmental
Response, Compensation and Liability Act of 1980, as amended from time to time,
or any comparable law, unless the Servicer has also previously determined, based
on its reasonable judgment and a report prepared by a Person who regularly
conducts environmental audits using customary industry standards, that:

                  (1) such Mortgaged Property is in compliance with applicable
            environmental laws or, if not, that it would be in the best economic
            interest of the Trust Fund to take such actions as are necessary to
            bring the Mortgaged Property into compliance therewith; and

                  (2) there are no circumstances present at such Mortgaged
            Property relating to the use, management or disposal of any
            hazardous substances, hazardous materials, hazardous wastes, or
            petroleum-based materials for which investigation, testing,
            monitoring, containment, clean-up or remediation could be required
            under any federal, state or local law or regulation, or that if any
            such


                                        80
<PAGE>

            materials are present for which such action could be required, that
            it would be in the best economic interest of the Trust Fund to take
            such actions with respect to the affected Mortgaged Property.

            The cost of the environmental audit report contemplated by this
Section 3.16 shall be advanced by the Servicer, subject to the Servicer's right
to be reimbursed therefor from the Collection Account as provided in Section
3.11(a)(ix), such right of reimbursement being prior to the rights of
Certificateholders to receive any amount in the Collection Account received in
respect of the affected Mortgage Loan or other Mortgage Loans.

            If the Servicer determines, as described above, that it is in the
best economic interest of the Trust Fund to take such actions as are necessary
to bring any such Mortgaged Property into compliance with applicable
environmental laws, or to take such action with respect to the containment,
clean-up or remediation of hazardous substances, hazardous materials, hazardous
wastes or petroleum-based materials affecting any such Mortgaged Property, then
the Servicer shall take such action as it deems to be in the best economic
interest of the Trust Fund. The cost of any such compliance, containment,
cleanup or remediation shall be advanced by the Servicer, subject to the
Servicer's right to be reimbursed therefor from the Collection Account as
provided in Section 3.11(a)(ix), such right of reimbursement being prior to the
rights of Certificateholders to receive any amount in the Collection Account
received in respect of the affected Mortgage Loan or other Mortgage Loans.

            (c) The Servicer shall have the right to purchase from REMIC I any
defaulted Mortgage Loan that is 90 days or more delinquent, which the Servicer
determines in good faith will otherwise become subject to foreclosure
proceedings (evidence of such determination to be delivered in writing to the
Trustee and the Trust Administrator, in form and substance satisfactory to the
Trustee and the Trust Administrator prior to purchase), at a price equal to the
Purchase Price. The Purchase Price for any Mortgage Loan purchased hereunder
shall be deposited in the Collection Account, and the Trust Administrator, upon
receipt of written certification from the Servicer of such deposit, shall
release or cause to be released to the Servicer the related Mortgage File and
the Trust Administrator, upon receipt of written certification from the Servicer
of such deposit, shall execute and deliver such instruments of transfer or
assignment, in each case without recourse, as the Servicer shall furnish and as
shall be necessary to vest in the Servicer title to any Mortgage Loan released
pursuant hereto.

             (d) Proceeds received in connection with any Final Recovery
Determination, as well as any recovery resulting from a partial collection of
Insurance Proceeds or Liquidation Proceeds, in respect of any Mortgage Loan,
will be applied in the following order of priority: first, to reimburse the
Servicer or any Sub-Servicer for any related unreimbursed Servicing Advances and
P&I Advances, pursuant to Section 3.11(a)(ii) or (a)(iii)(B); second, to accrued
and unpaid interest on the Mortgage Loan, to the date of the Final Recovery
Determination, or to the Due Date prior to the Distribution Date on which such
amounts are to be distributed if not in connection with a Final Recovery
Determination; and third, as a recovery of principal of the Mortgage Loan. If
the amount of the recovery so allocated to interest is less than the full amount
of accrued and unpaid interest due on such Mortgage Loan, the amount of such
recovery will be allocated by the Servicer as follows: first, to unpaid
Servicing Fees; and second, to the balance of


                                       81

the interest then due and owing. The portion of the recovery so allocated to
unpaid Servicing Fees shall be reimbursed to the Servicer or any Sub-Servicer
pursuant to Section 3.11(a)(iii)(A).

            SECTION 3.17       Trustee to Cooperate; Release of Mortgage Files.

            (a) Upon the payment in full of any Mortgage Loan, or the receipt by
the Servicer of a notification that payment in full shall be escrowed in a
manner customary for such purposes, the Servicer will immediately notify the
related Custodian, on behalf of the Trustee, by a Request for Release in the
form of Exhibit E (which certification shall include a statement to the effect
that all amounts received or to be received in connection with such payment
which are required to be deposited in the Collection Account pursuant to Section
3.10 have been or will be so deposited) of a Servicing Officer and shall request
that the related Custodian, on behalf of the Trustee, deliver to it the Mortgage
File. Upon receipt of such certification and request, the related Custodian, on
behalf of the Trustee, shall promptly release the related Mortgage File to the
Servicer, and the Servicer is authorized to cause the removal from the
registration on the MERS(R) System of any such Mortgage, if applicable, and to
execute and deliver, on behalf of the Trustee and the Certificateholders or any
of them, any and all instruments of satisfaction or cancellation or of partial
or full release. No expenses incurred in connection with any instrument of
satisfaction or deed of reconveyance shall be chargeable to the Collection
Account or the Distribution Account.

            The Trustee (or a Custodian on its behalf) shall, at the written
request and expense of any Certificateholder, provide a written report to such
Certificateholder of all Mortgage Files released to the Servicer for servicing
purposes.

            (b) From time to time and as appropriate for the servicing or
foreclosure of any Mortgage Loan, including, for this purpose, collection under
any insurance policy relating to the Mortgage Loans, the related Custodian, on
behalf of the Trustee, shall, upon request of the Servicer and delivery to the
related Custodian and the Trustee of a Request for Release in the form of
Exhibit E, release the related Mortgage File to the Servicer, and the related
Custodian, on behalf of the Trustee, shall, at the direction of the Servicer,
execute such documents as shall be necessary to the prosecution of any such
proceedings. Such Request for Release shall obligate the Servicer to return each
and every document previously requested from the Mortgage File to the related
Custodian when the need therefor by the Servicer no longer exists, unless the
Mortgage Loan has been liquidated and the Liquidation Proceeds relating to the
Mortgage Loan have been deposited in the Collection Account or the Mortgage File
or such document has been delivered to an attorney, or to a public trustee or
other public official as required by law, for purposes of initiating or pursuing
legal action or other proceedings for the foreclosure of the Mortgaged Property
either judicially or non-judicially, and the Servicer has delivered to the
related Custodian, on behalf of the Trustee, a certificate of a Servicing
Officer certifying as to the name and address of the Person to which such
Mortgage File or such document was delivered and the purpose or purposes of such
delivery. Upon receipt of a certificate of a Servicing Officer stating that such
Mortgage Loan was liquidated and that all amounts received or to be received in
connection with such liquidation that are required to be deposited into the
Collection Account have been so deposited, or that such Mortgage Loan has become
an REO Property, a copy of the Request for Release shall be released by the
related Custodian, on behalf of the Trustee, to the Servicer.


                                       82
<PAGE>

            (c) Upon written certification of a Servicing Officer, the Trustee
shall execute and deliver to the Servicer any court pleadings, requests for
trustee's sale or other documents reasonably necessary to the foreclosure or
trustee's sale in respect of a Mortgaged Property or to any legal action brought
to obtain judgment against any Mortgagor on the Mortgage Note or Mortgage or to
obtain a deficiency judgment, or to enforce any other remedies or rights
provided by the Mortgage Note or Mortgage or otherwise available at law or in
equity. Each such certification shall include a request that such pleadings or
documents be executed by the Trustee and a statement as to the reason such
documents or pleadings are required and that the execution and delivery thereof
by the Trustee will not invalidate or otherwise affect the lien of the Mortgage,
except for the termination of such a lien upon completion of the foreclosure or
trustee's sale.

            SECTION 3.18       Servicing Compensation.

            As compensation for the activities of the Servicer hereunder, the
Servicer shall be entitled to the Servicing Fee with respect to each Mortgage
Loan payable solely from payments of interest in respect of such Mortgage Loan,
subject to Section 3.24. In addition, the Servicer shall be entitled to recover
unpaid Servicing Fees out of Insurance Proceeds or Liquidation Proceeds to the
extent permitted by Section 3.11(a)(iii)(A) and out of amounts derived from the
operation and sale of an REO Property to the extent permitted by Section 3.23.
The right to receive the Servicing Fee may not be transferred in whole or in
part except in connection with the transfer of all of the Servicer's
responsibilities and obligations under this Agreement.

            Additional servicing compensation in the form of assumption fees,
late payment charges and other similar fees and charges (other than Prepayment
Charges) shall be retained by the Servicer (subject to Section 3.24) only to the
extent such fees or charges are received by the Servicer. The Servicer shall
also be entitled pursuant to Section 3.11(a)(iv) to withdraw from the Collection
Account, and pursuant to Section 3.23(b) to withdraw from any REO Account, as
additional servicing compensation, interest or other income earned on deposits
therein, subject to Section 3.12 and Section 3.24. The Servicer shall be
required to pay all expenses incurred by it in connection with its servicing
activities hereunder (including premiums for the insurance required by Section
3.14, to the extent such premiums are not paid by the related Mortgagors or by a
Sub-Servicer, servicing compensation of each Sub-Servicer, and to the extent
provided herein in Section 8.05, the fees and expenses of the Trustee and the
Trust Administrator) and shall not be entitled to reimbursement therefor except
as specifically provided herein.

            SECTION 3.19       Reports to the Trust Administrator; Collection
                              Account Statements.

            Not later than fifteen days after each Distribution Date, the
Servicer shall forward to the Trust Administrator, upon the request of the Trust
Administrator, a statement prepared by the Servicer setting forth the status of
the Collection Account as of the close of business on the last day of the
calendar month relating to such Distribution Date and showing, for the period
covered by such statement, the aggregate amount of deposits into and withdrawals
from the Collection Account of each category of deposit specified in Section
3.10(a) and each category of withdrawal specified in Section 3.11. Such
statement may be in the form of the then current Fannie Mae Monthly Accounting
Report for its Guaranteed Mortgage Pass-Through Program


                                       83
<PAGE>

with appropriate additions and changes, and shall also include information as to
the aggregate of the outstanding principal balances of all of the Mortgage Loans
as of the last day of the calendar month immediately preceding such Distribution
Date. Copies of such statement shall be provided by the Trust Administrator to
any Certificateholder and to any Person identified to the Trust Administrator as
a prospective transferee of a Certificate, upon the request and at the expense
of the requesting party, provided such statement is delivered by the Servicer to
the Trust Administrator.

             SECTION 3.20       Statement as to Compliance.

            The Servicer shall deliver to the Trust Administrator, on or before
March 15th of each calendar year beginning in 2007, an Officers' Certificate (an
"Annual Statement of Compliance") stating, as to each signatory thereof, that
(i) a review of the activities of the Servicer during the preceding calendar
year and of performance under this Agreement has been made under such officers'
supervision and (ii) to the best of such officers' knowledge, based on such
review, the Servicer has fulfilled all of its obligations under this Agreement
in all material respects throughout such year, or, if there has been a failure
to fulfill any such obligation in any material respect, specifying each such
failure known to such officer and the nature and status of cure provisions
thereof. The Servicer shall deliver, or cause any Sub-Servicer to deliver, a
similar Annual Statement of Compliance by any Sub-Servicer to which the Servicer
has delegated any servicing responsibilites with respect to the Mortgage Loans,
to the Trust Administrator as described above as and when required with respect
to the Servicer.

            If the Servicer cannot deliver the related Annual Statement of
Compliance by March 15th of such year, the Trust Administrator, at its sole
option, may permit a cure period for the Servicer to deliver such Annual
Statement of Compliance, but in no event later than March 20th of such year.

            Failure of the Servicer to timely comply with this Section 3.20,
which continues unremedied for ten (10) calendar days after the date on which
the Annual Statement of Compliance was required to be delivered, shall be deemed
an Event of Default, and upon the receipt of written notice from the Trust
Administrator of such Event of Default, the Trustee may at the direction of the
Depositor, in addition to whatever rights the Trustee may have under this
Agreement and at law or equity or to damages, including injunctive relief and
specific performance, upon notice immediately terminate all the rights and
obligations of the Servicer under this Agreement and in and to the Mortgage
Loans and the proceeds thereof without compensating the Servicer for the same;
PROVIDED that to the extent that any provision of this Agreement expressly
provides for the survival of certain rights or obligations following termination
of the Servicer, such provision shall be given effect. This paragraph shall
supercede any other provision in this Agreement or any other agreement to the
contrary.

            The Servicer shall indemnify and hold harmless the Depositor, the
Trust Administrator and their officers, directors and Affiliates from and
against any actual losses, damages, penalties, fines, forfeitures, reasonable
and necessary legal fees and related costs, judgments and other costs and
expenses that such Person may sustain based upon a breach of the Servicer's
obligations under this Section 3.20.

            SECTION 3.21       Assessments of Compliance and Attestation Reports.

            (a) The Servicer shall service and administer the Mortgage Loans in
accordance with all applicable requirements of the Servicing Criteria (as set
forth in Exhibit C hereto). The Servicer shall deliver to the Trust
Administrator on or before March 1st of each calendar year beginning in 2007,
the following:

            (i) a report (an "Assessment of Compliance") regarding the
      Servicer's assessment of compliance with the Servicing Criteria during the
      immediately preceding calendar year, as required under Rules 13a-18 and
      15d-18 of the Exchange Act and Item 1122 of Regulation AB. Such report
      shall be signed by an authorized officer of the Servicer, and shall
      address each of the Servicing Criteria set forth in Exhibit C hereto;

            (ii) a report (an "Attestation Report") of a registered public
      accounting firm reasonably acceptable to the Depositor that attests to,
      and reports on, the assessment of compliance made by the Servicer and
      delivered pursuant to the preceding paragraph. Such attestation shall be
      in accordance with Rules 1-02(a)(3) and 2-02(g) of Regulation S-X under
      the Securities Act and the Exchange Act; and

            (iii) cause each Sub-Servicer, and each subcontractor determined by
      the Servicer to be "participating in the servicing function" within the
      meaning of Item 1122 of Regulation AB, to deliver an Assessment of
      Compliance and Attestation Report as and when provided in paragraphs (i)
      and (ii) of this Section 3.21(a).

            (iv) a statement as to which of the Servicing Criteria, if any, are
      not applicable to the Servicer, which statement shall be based on the
      activities it performs with respect to asset-backed securities
      transactions taken as a whole involving the Servicer, that are backed by
      the same asset type as the Mortgage Loans.

            (b) The Servicer shall, or shall cause any Sub-Servicer and each
subcontractor determined by the Servicer to be "participating in the servicing
function" within the meaning of Item 1122 of Regulation AB to, deliver to the
Trust Administrator and the Depositor an Assessment of Compliance and
Attestation Report as and when provided above.

            Such Assessment of Compliance, as to any Sub-Servicer, shall at a
minimum address each of the Servicing Criteria specified on Exhibit C hereto
which are indicated as applicable to any "primary servicer." Notwithstanding the
foregoing, as to any subcontractor, an Assessment of Compliance is not required
to be delivered unless it is required as part of a Form 10-K with respect to the
Trust Fund.

            If the Servicer cannot deliver any Assessment of Compliance or
Attestation Report by March 1st of such year, the Trust Administrator, at its
sole option, may permit a cure period for the Servicer to deliver such
Assessment of Compliance or Attestation Report, but in no event later than March
15th of such year.

            Failure of the Servicer to timely comply with this Section 3.21
shall be deemed a Servicer Event of Default, and upon the receipt of written
notice from the Trust Administrator of such Event of Default, the Trustee at the
direction of the Depositor may, in addition to whatever


                                       85
<PAGE>

rights the Trustee may have under this Agreement and at law or equity or to
damages, including injunctive relief and specific performance, upon notice
immediately terminate all the rights and obligations of the Servicer under this
Agreement and in and to the Mortgage Loans and the proceeds thereof without
compensating the Servicer for the same; provided, however, the Depositor shall
not be entitled to instruct the Trustee to terminate the rights and obligations
of the Servicer pursuant to clause (iii) above if a failure of the Servicer to
identify a subcontractor "participating in th
