of November 1, 2000, among Impac Secured Assets Corp., as company (the
"Company"), Impac Funding Corporation, as master servicer (the "Master
Servicer"), and Bankers Trust Company of California, N.A., as trustee (the

                             PRELIMINARY STATEMENT:

                  The Company intends to sell pass-through certificates
(collectively, the "Certificates"), to be issued hereunder in multiple classes,
which in the aggregate will evidence the entire beneficial ownership interest in
the Trust Fund created hereunder. The Certificates will consist of eleven
classes of certificates, designated as (i) the Class A-1 Certificates, (ii) the
Class A-2 Certificates, (iii) the Class A-3 Certificates, (iv) the Class A-4
Certificates, (v) the Class A-IO Certificates, (vi) the Class M-1 Certificates,
(vii) the Class M-2 Certificates, (viii) the Class B Certificates, (ix) the
Class P Certificates, (x) the Class C Certificates and (xi) the Class R
Certificates.

                                     -------

         As provided herein, the Trustee will make an election to treat the
segregated pool of assets consisting of the Mortgage Loans and certain other
related assets subject to this Agreement as a real estate mortgage investment
conduit (a "REMIC") for federal income tax purposes, and such segregated pool of
assets will be designated as "REMIC 1." The Class R-1 Interest will represent
the sole class of "residual interests" in REMIC 1 for purposes of the REMIC
Provisions (as defined herein) under federal income tax law. The following table
irrevocably sets forth the designation, the Uncertificated REMIC 1 Pass-Through
Rate, the initial Uncertificated Principal Balance, and solely for purposes of
satisfying Treasury regulation Section 1.860G-1(a)(4)(iii), the "latest possible

                          CONVEYANCE OF MORTGAGE LOANS;
                        ORIGINAL ISSUANCE OF CERTIFICATES

                  SECTION 2.01.             Conveyance of Mortgage Loans.

                  The Company, as of the Closing Date, and concurrently with the
execution and delivery hereof, does hereby assign, transfer, sell, set over and
otherwise convey to the Trustee without recourse all the right, title and
interest of the Company in and to the Mortgage Loans identified on the Mortgage
Loan Schedule (exclusive of any prepayment fees and late payment charges
received thereon) and all other assets included or to be included in the Trust
Fund for the benefit of the Certificateholders. Such assignment includes all
principal and interest received by the Master Servicer on or with respect to the
Mortgage Loans (other than payment of principal and interest due on or before
the Cut-off Date).

                  The Master Servicer hereby acknowledges the receipt by it of
cash in an amount equal to $57,918 (the "Special Deposit"), representing
interest at the Mortgage Rate, for the calendar month of November 2000, for
those Mortgage Loans which do not have Monthly Payments due on December 1, 2000.
The Master Servicer shall hold such amount in the Custodial Account, and such
amount (other than an amount equal to interest on such Mortgage Loans for such
period at a per annum rate equal to the sum of the Servicing Fee Rate, the
Trustee Fee Rate and the Radian PMI Policy Rate) shall be included in the
Available Distribution Amount for the Distribution Date in December 2000.

                  In connection with such transfer and assignment, the Company
has caused the Seller to deliver to, and deposit with the Trustee, as described
in the Mortgage Loan Purchase Agreement the following documents or instruments:

                (i) the original Mortgage Note endorsed without recourse,
         "Bankers Trust Company of California, N.A., as trustee under the
         Pooling and Servicing Agreement relating to Impac Secured Assets Corp.,
         Mortgage Pass-Through Certificates, Series 2000-4" with all intervening
         endorsements showing an unbroken chain of endorsements from the
         originator to the Person endorsing it to the Trustee or, with respect
         to any Mortgage Loan as to which the original Mortgage Note has been
         permanently lost or destroyed and has not been replaced, a Lost Note
         Affidavit;

               (ii) the original recorded Mortgage or, if the original Mortgage
         has not been returned from the public recording office, a copy of the
         Mortgage certified by the Seller or the public recording office in
         which such Mortgage has been recorded to be a true and complete copy of
         the original Mortgage submitted for recording;

              (iii) a duly executed original Assignment of the Mortgage, without
         recourse, in recordable form to "Bankers Trust Company of California,
         N.A., as trustee," or to "Bankers


                                       40

         Trust Company of California, N.A., as trustee for holders of Impac
         Secured Assets Corp., Mortgage Pass-Through Certificates, Series
         2000-4";

               (iv) the original recorded Assignment or Assignments of the
         Mortgage showing an unbroken chain of assignment from the originator
         thereof to the Person assigning it to the Trustee or, if any such
         Assignment has not been returned from the applicable public recording
         office, a copy of such Assignment certified by the Seller to be a true
         and complete copy of the original Assignment submitted to the title
         insurance company for recording;

                (v) the original title insurance policy, or, if such policy has
         not been issued, any one of an original or a copy of the preliminary
         title report, title binder or title commitment on the Mortgaged
         Property with the original policy of the insurance to be delivered
         promptly following the receipt thereof;

              (vi) a copy of the related hazard insurance policy;

              (vii) a true and correct copy of any assumption, modification,
         consolidation or substitution agreement; and

             (viii) the original or a copy of the private mortgage insurance
         policy or original certificate of private mortgage insurance for each
         Mortgage Loan so identified on the Mortgage Loan Schedule (other than a
         Radian Lender-Paid PMI Policy).

                  The Seller is obligated as described in the Mortgage Loan
Purchase Agreement to deliver to the Trustee: (a) either the original recorded
Mortgage, or in the event such original cannot be delivered by the Seller, a
copy of such Mortgage certified as true and complete by the appropriate
recording office, in those instances where a copy thereof certified by the
Seller was delivered to the Trustee pursuant to clause (ii) above; and (b)
either the original Assignment or Assignments of the Mortgage, with evidence of
recording thereon, showing an unbroken chain of assignment from the originator
to the Seller, or in the event such original cannot be delivered by the Seller,
a copy of such Assignment or Assignments certified as true and complete by the
appropriate recording office, in those instances where copies thereof certified
by the Seller were delivered to the Trustee pursuant to clause (iv) above.
However, pursuant to the Mortgage Loan Purchase Agreement, the Seller need not
cause to be recorded any assignment in any jurisdiction under the laws of which,
as evidenced by an Opinion of Counsel delivered by the Seller to the Trustee and
the Rating Agencies, the recordation of such assignment is not necessary to
protect the Trustee's interest in the related Mortgage Loan; provided, however,
notwithstanding the delivery of any Opinion of Counsel, each assignment shall be
submitted for recording by the Seller in the manner described above, at no
expense to the Trust or the Trustee, upon the earliest to occur of: (i)
direction by the Holders of Certificates evidencing at least 25% of the Voting
Rights, (ii) the occurrence of a Event of Default, (iii) the occurrence of a
bankruptcy, insolvency or foreclosure relating to the Seller, (iv) the
occurrence of a servicing transfer as described in Section 7.02 hereof and (v)
if the Seller is not the Master Servicer and with respect to any one assignment,
the occurrence of a bankruptcy, insolvency or foreclosure relating to the
Mortgagor under the related Mortgage.

                  Notwithstanding anything to the contrary contained in this
Section 2.01, in those instances where the public recording office retains the
original Mortgage after it has been recorded, the Seller shall be deemed to have
satisfied its obligations hereunder upon delivery to the Trustee of a copy of
such Mortgage certified by the public recording office to be a true and complete
copy of the recorded original thereof.

                  If any Assignment is lost or returned unrecorded to the
Trustee because of any defect therein, the Seller is required, as described in
the Mortgage Loan Purchase Agreement, to prepare a substitute Assignment or cure
such defect, as the case may be, and the Seller shall cause such Assignment to
be recorded in accordance with this section.

                  The Seller is required as described in the Mortgage Loan
Purchase Agreement to exercise its best reasonable efforts to deliver or cause
to be delivered to the Trustee within 120 days of the Closing Date the original
or a photocopy of the title insurance policy with respect to each Mortgage Loan
assigned to the Trustee pursuant to this Section 2.01.

                  All original documents relating to the Mortgage Loans which
are not delivered to the Trustee are and shall be held by the Master Servicer in
trust for the benefit of the Trustee on behalf of the Certificateholders.

                  Except as may otherwise expressly be provided herein, none of
the Company, the Master Servicer or the Trustee shall (and the Master Servicer
shall ensure that no Sub-Servicer shall) assign, sell, dispose of or transfer
any interest in the Trust Fund or any portion thereof, or cause the Trust Fund
or any portion thereof to be subject to any lien, claim, mortgage, security
interest, pledge or other encumbrance.

                  It is intended that the conveyance of the Mortgage Loans by
the Company to the Trustee as provided in this Section be, and be construed as,
a sale of the Mortgage Loans and the REMIC 1 Regular Interests as provided for
in this Section 2.01 by the Company to the Trustee for the benefit of the
Certificateholders. It is, further, not intended that such conveyance be deemed
a pledge of the Mortgage Loans and the REMIC 1 Regular Interests by the Company
to the Trustee to secure a debt or other obligation of the Company. However, in
the event that the Mortgage Loans and the REMIC 1 Regular Interests are held to
be property of the Company, or if for any reason this Agreement is held or
deemed to create a security interest in the Mortgage Loans and the REMIC 1
Regular Interests, then it is intended that, (a) this Agreement shall also be
deemed to be a security agreement within the meaning of Articles 8 and 9 of the
New York Uniform Commercial Code and the Uniform Commercial Code of any other
applicable jurisdiction; (b) the conveyance provided for in this Section shall
be deemed to be (1) a grant by the Company to the Trustee of a security interest
in all of the Company's right (including the power to convey title thereto),
title and interest, whether now owned or hereafter acquired, in and to (A) the
Mortgage Loans, including the Mortgage Notes, the Mortgages, any related
Insurance Policies and all other documents in the related Mortgage Files, (B)
all amounts payable to the holders of the Mortgage Loans in accordance with the
terms thereof, (C) the REMIC 1 Regular Interests and (D) all proceeds of the
conversion, voluntary or involuntary, of the foregoing into cash, instruments,
securities or other property, including without limitation all


                                       42

<PAGE>



amounts from time to time held or invested in the Certificate Account or the
Custodial Account, whether in the form of cash, instruments, securities or other
property and (2) an assignment by the Company to the Trustee of any security
interest in any and all of the Seller's right (including the power to convey
title thereto), title and interest, whether now owned or hereafter acquired, in
and to the property described in the foregoing clauses (1)(A) through (D); (c)
the possession by the Trustee or any other agent of the Trustee of Mortgage
Notes and such other items of property as constitute instruments, money,
negotiable documents or chattel paper shall be deemed to be "possession by the
secured party" or possession by a purchaser or a person designated by such
secured party, for purposes of perfecting the security interest pursuant to the
New York Uniform Commercial Code and the Uniform Commercial Code of any other
applicable jurisdiction (including, without limitation, Sections 9-115, 9-305,
8-102, 8-301, 8-501 and 8-503 thereof); and (d) notifications to persons holding
such property, and acknowledgments, receipts or confirmations from persons
holding such property, shall be deemed notifications to, or acknowledgments,
receipts or confirmations from, financial intermediaries, bailees or agents (as
applicable) of the Trustee for the purpose of perfecting such security interest
under applicable law. The Company and the Trustee shall, to the extent
consistent with this Agreement, take such actions as may be necessary to ensure
that, if this Agreement were deemed to create a security interest in the
Mortgage Loans and the REMIC 1 Regular Interests, such security interest would
be deemed to be a perfected security interest of first priority under applicable
law and will be maintained as such throughout the term of the Agreement.

                  SECTION 2.02.             Acceptance of the Trust Fund by the
                                            Trustee.

                  The Trustee acknowledges receipt (subject to any exceptions
noted in the Initial Certification described below), of the documents referred
to in Section 2.01 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 Files, and that it
holds or will hold such other assets included in the definition of "Trust Fund"
(to the extent delivered or assigned to the Trustee), in trust for the exclusive
use and benefit of all present and future Certificateholders.

                  The Trustee agrees, for the benefit of the Certificateholders,
to review or cause to be reviewed on its behalf, each Mortgage File on or before
the Closing Date to ascertain that all documents required to be delivered to it
are in its possession, and the Trustee agrees to execute and deliver, or cause
to be executed and delivered, to the Company and the Master Servicer on the
Closing Date, an Initial Certification in the form annexed hereto as Exhibit C
to the effect that, as to each Mortgage Loan listed in the Mortgage Loan
Schedule (other than any Mortgage Loan paid in full or any Mortgage Loan
specifically identified in such certification as not covered by such
certification), (i) all documents required to be delivered to it pursuant to
this Agreement with respect to such Mortgage Loan are in its possession, (ii)
such documents have been reviewed by it and appear regular on their face and
relate to such Mortgage Loan and (iii) based on its examination and only as to
the foregoing documents, the information set forth in items (i), (ii), (iii) and
(iv) of the definition of the "Mortgage Loan Schedule" accurately reflects
information set forth in the Mortgage File. Neither the Trustee nor the Master
Servicer shall be under any duty to determine whether any


                                       43

<PAGE>



Mortgage File should include any of the documents specified in clause (vi) or
(vii) of Section 2.01. Neither the Trustee nor the Master Servicer shall be
under any duty or obligation to inspect, review or examine said documents,
instruments, certificates or other papers to determine that the same are
genuine, enforceable or appropriate for the represented purpose or that they
have actually been recorded, or they are in recordable form or that they are
other than what they purport to be on their face.

                  Within 90 days of the Closing Date the Trustee shall deliver
to the Company and the Master Servicer a Final Certification in the form annexed
hereto as Exhibit D evidencing the completeness of the Mortgage Files, with any
applicable exceptions noted thereon.

                  If in the process of reviewing the Mortgage Files and
preparing the certifications referred to above the Trustee finds any document or
documents constituting a part of a Mortgage File to be missing or defective in
any material respect, the Trustee shall promptly notify the Seller, the Master
Servicer and the Company. The Trustee shall promptly notify the Seller of such
defect and request that the Seller cure any such defect within 60 days from the
date on which the Seller was notified of such defect, and if the Seller does not
cure such defect in all material respects during such period, request on behalf
of the Certificateholders that the Seller purchase such Mortgage Loan from the
Trust Fund at the Purchase Price within 90 days after the date on which the
Seller was notified of such defect; provided that if such defect would cause the
Mortgage Loan to be other than a "qualified mortgage" as defined in Section
860G(a)(3) of the Code, any such cure or repurchase must occur within 90 days
from the date such breach was discovered. It is understood and agreed that the
obligation of the Seller to cure a material defect in, or purchase any Mortgage
Loan as to which a material defect in a constituent document exists shall
constitute the sole remedy respecting such defect available to
Certificateholders or the Trustee on behalf of Certificateholders. The Purchase
Price for the purchased Mortgage Loan shall be deposited or caused to be
deposited upon receipt by the Master Servicer in the Custodial Account and, upon
receipt by the Trustee of written notification of such deposit signed by a
Servicing Officer, the Trustee shall release or cause to be released to the
Seller the related Mortgage File and shall execute and deliver such instruments
of transfer or assignment, in each case without recourse, as the Seller shall
require as necessary to vest in the Seller ownership of any Mortgage Loan
released pursuant hereto and at such time the Trustee shall have no further
responsibility with respect to the related Mortgage File.

                  SECTION 2.03.             Representations, Warranties and
                                            Covenants of the Master Servicer and
                                            the Company.

                  (a) The Master Servicer hereby represents and warrants to and
covenants with the Company and the Trustee for the benefit of Certificateholders
that:

                        (i) The Master Servicer is, and throughout the term
         hereof shall remain, a corporation duly organized, validly existing and
         in good standing under the laws of the state of its incorporation
         (except as otherwise permitted pursuant to Section 6.02), the Master
         Servicer is, and shall remain, in compliance with the laws of each
         state in which any Mortgaged Property is located to the extent
         necessary to perform its obligations under this


                                       44

<PAGE>



         Agreement, and the Master Servicer is, and shall remain, approved to
         sell mortgage loans to and service mortgage loans for Fannie Mae and
         Freddie Mac;

                       (ii) The execution and delivery of this Agreement by the
         Master Servicer, and the performance and compliance with the terms of
         this Agreement by the Master Servicer, will not violate the Master
         Servicer's articles of incorporation or bylaws or constitute a default
         (or an event which, with notice or lapse of time, or both, would
         constitute a default) under, or result in the breach of, any material
         agreement or other instrument to which it is a party or which is
         applicable to it or any of its assets;

                      (iii) The Master Servicer has the full power and authority
         to enter into and consummate all transactions contemplated by this
         Agreement, has duly authorized the execution, delivery and performance
         of this Agreement, and has duly executed and delivered this Agreement;

                       (iv) This Agreement, assuming due authorization,
         execution and delivery by the Company and the Trustee, constitutes a
         valid, legal and binding obligation of the Master Servicer, enforceable
         against the Master Servicer in accordance with the terms hereof,
         subject to (A) applicable bankruptcy, insolvency, reorganization,
         moratorium and other laws affecting the enforcement of creditors'
         rights generally, and (B) general principles of equity, regardless of
         whether such enforcement is considered in a proceeding in equity or at
         law;

                        (v) The Master Servicer is not in violation of, and its
         execution and delivery of this Agreement and its performance and
         compliance with the terms of this Agreement will not constitute a
         violation of, any law, any order or decree of any court or arbiter, or
         any order, regulation or demand of any federal, state or local
         governmental or regulatory authority, which violation is likely to
         affect materially and adversely either the ability of the Master
         Servicer to perform its obligations under this Agreement or the
         financial condition of the Master Servicer;

                       (vi) No litigation is pending (other than litigation with
         respect to which pleadings or documents have been filed with a court,
         but not served on the Master Servicer) or, the best of the Master
         Servicer's knowledge, threatened against the Master Servicer which
         would prohibit its entering into this Agreement or performing its
         obligations under this Agreement or is likely to affect materially and
         adversely either the ability of the Master Servicer to perform its
         obligations under this Agreement or the financial condition of the
         Master Servicer;

                      (vii) The Master Servicer will comply in all material
         respects in the performance of this Agreement with all reasonable rules
         and requirements of each insurer under each Insurance Policy;

                      (viii) The execution of this Agreement and the performance
         of the Master Servicer's obligations hereunder do not require any
         license, consent or approval of any state


                                       45

<PAGE>



         or federal court, agency, regulatory authority or other governmental
         body having jurisdiction over the Master Servicer, other than such as
         have been obtained;

                       (ix) No information, certificate of an officer, statement
         furnished in writing or report delivered to the Company, any affiliate
         of the Company or the Trustee by the Master Servicer in its capacity as
         Master Servicer, and not in its capacity as a Seller hereunder, will,
         to the knowledge of the Master Servicer, contain any untrue statement
         of a material fact; and

                        (x) The Master Servicer will not waive any Prepayment
         Charge unless it is waived in accordance with the standard set forth in
         Section 3.01.

                  It is understood and agreed that the representations,
warranties and covenants set forth in this Section 2.03(a) shall survive the
execution and delivery of this Agreement, and shall inure to the benefit of the
Company, the Trustee and the Certificateholders. Upon discovery by the Company,
the Trustee or the Master Servicer of a breach of any of the foregoing
representations, warranties and covenants that materially and adversely affects
the interests of the Company or the Trustee, the party discovering such breach
shall give prompt written notice to the other parties. Notwithstanding the
foregoing, within 90 days of the earlier of discovery by the Master Servicer or
receipt of notice by the Master Servicer of the breach of the covenant of the
Master Servicer set forth in Section 2.03(x) above which materially and
adversely affects the interests of the Holders of the Class P Certificates in
any Prepayment Charge, the Master Servicer shall remedy such breach as follows:
the Master Servicer shall pay the amount of such waived Prepayment Charge, for
the benefit of the holders of the Class P Certificates, by depositing such
amount into the Custodial Account (net of any amount actually collected by the
Master Servicer in respect of such Prepayment Charge and remitted by the Master
Servicer, for the benefit of the Holders of the Class P Certificates, in respect
of such Prepayment Charge, into the Custodial Account). The foregoing shall not,
however, limit any remedies available to the Certificateholders, the Company or
the Trustee on behalf of the Certificateholders, pursuant to the Mortgage Loan
Purchase Agreement respecting a breach of any of the representations, warranties
and covenants contained in the Mortgage Loan Purchase Agreement.

                  (b) The Company hereby represents and warrants to the Master
Servicer and the Trustee for the benefit of Certificateholders that as of the
Closing Date, the representations and warranties of the Seller with respect to
the Mortgage Loans and the remedies therefor that are contained in the Mortgage
Loan Purchase Agreement are as set forth in Exhibit I hereto.

                  It is understood and agreed that the representations and
warranties set forth in this Section 2.03(b) shall survive delivery of the
respective Mortgage Files to the Trustee.

                  Upon discovery by either the Company, the Master Servicer or
the Trustee of a breach of any representation or warranty set forth in this
Section 2.03 which materially and adversely affects the interests of the
Certificateholders in any Mortgage Loan, the party discovering such breach shall
give prompt written notice to the other parties.

                  SECTION 2.04.             Representations and Warranties of
                                            the Seller.

                  The Company hereby assigns to the Trustee for the benefit of
Certificateholders all of its rights (but none of its obligations) in, to and
under the Mortgage Loan Purchase Agreement. Insofar as the Mortgage Loan
Purchase Agreement relates to such representations and warranties and any
remedies provided thereunder for any breach of such representations and
warranties, such right, title and interest may be enforced by the Trustee on
behalf of the Certificateholders. Upon the discovery by the Company, the Master
Servicer or the Trustee of a breach of any of the representations and warranties
made in the Mortgage Loan Purchase Agreement in respect of any Mortgage Loan
which materially and adversely affects the interests of the Certificateholders
in such Mortgage Loan, the party discovering such breach shall give prompt
written notice to the other parties. The Trustee shall promptly notify the
Seller of such breach and request that the Seller shall, within 90 days from the
date that the Seller was notified or otherwise obtained knowledge of such
breach, either (i) cure such breach in all material respects or (ii) purchase
such Mortgage Loan from the Trust Fund at the Purchase Price and in the manner
set forth in Section 2.02; provided that if such breach would cause the Mortgage
Loan to be other than a "qualified mortgage" as defined in Section 860G(a)(3) of
the Code, any such cure or repurchase must occur within 90 days from the date
such breach was discovered. However, in the case of a breach under the Mortgage
Loan Purchase Agreement, subject to the approval of the Company the Seller shall
have the option to substitute a Qualified Substitute Mortgage Loan or Loans for
such Mortgage Loan if such substitution occurs within two years following the
Closing Date, except that if the breach would cause the Mortgage Loan to be
other than a "qualified mortgage" as defined in Section 860G(a)(3) of the Code,
any such substitution must occur within 90 days from the date the breach was
discovered if such 90 day period expires before two years following the Closing
Date. In the event that the Seller elects to substitute a Qualified Substitute
Mortgage Loan or Loans for a Deleted Mortgage Loan pursuant to this Section
2.04, the Trustee shall enforce the obligation of the Seller under the Mortgage
Loan Purchase Agreement to deliver to the Trustee and the Master Servicer, as
appropriate, with respect to such Qualified Substitute Mortgage Loan or Loans,
the original Mortgage Note, the Mortgage, an Assignment of the Mortgage in
recordable form, and such other documents and agreements as are required by
Section 2.01, with the Mortgage Note endorsed as required by Section 2.01. No
substitution will be made in any calendar month after the Determination Date for
such month. Monthly Payments due with respect to Qualified Substitute Mortgage
Loans in the month of substitution, to the extent received by the Master
Servicer or any Sub-Servicer, shall not be part of the Trust Fund and will be
retained by the Master Servicer and remitted by the Master Servicer to the
Seller on the next succeeding Distribution Date. For the month of substitution,
distributions to Certificateholders will include the Monthly Payment due on a
Deleted Mortgage Loan for such month and thereafter the Seller shall be entitled
to retain all amounts received in respect of such Deleted Mortgage Loan. The
Company shall amend or cause to be amended the Mortgage Loan Schedule for the
benefit of the Certificateholders to reflect the removal of such Deleted
Mortgage Loan and the substitution of the Qualified Substitute Mortgage Loan or
Loans and the Company shall deliver the amended Mortgage Loan Schedule to the
Trustee. Upon such substitution, the Qualified Substitute Mortgage Loan or Loans
shall be subject to the terms of this Agreement in all respects, the Seller
shall be deemed to have made the representations and warranties with respect to
the Qualified Substitute Mortgage Loan contained in the Mortgage Loan Purchase
Agreement as of the


                                       47

<PAGE>



date of substitution, and the Company shall be deemed to have made with respect
to any Qualified Substitute Mortgage Loan or Loans, as of the date of
substitution, the representations and warranties set forth in Exhibit I hereof
(other than representations (xiv), (xvi), (xxix) and (xxxiii) through (xli)).

                  In connection with the substitution of one or more Qualified
Substitute Mortgage Loans for one or more Deleted Mortgage Loans, the Master
Servicer will determine the amount (the Substitution Adjustment"), if any, by
which the aggregate principal balance of all such Qualified Substitute Mortgage
Loans as of the date of substitution is less than the aggregate Stated Principal
Balance of all such Deleted Mortgage Loans (in each case after application of
the principal portion of the Monthly Payments due in the month of substitution
that are to be distributed to Certificateholders in the month of substitution).
The Trustee shall enforce the obligation of the Seller under the Mortgage Loan
Purchase Agreement to provide the Master Servicer on the day of substitution for
immediate deposit into the Custodial Account the amount of such shortfall,
without any reimbursement therefor. In accordance with the Mortgage Loan
Purchase Agreement, the Seller shall give notice in writing to the Trustee of
such event, which notice shall be accompanied by an Officers' Certificate as to
the calculation of such shortfall and by an Opinion of Counsel to the effect
that such substitution will not cause (a) any federal tax to be imposed on REMIC
1, REMIC 2 or REMIC 3, 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 portion of REMIC 1, REMIC 2 or REMIC 3 to fail to qualify as a REMIC at
any time that any Certificate is outstanding. The costs of any substitution as
described above, including any related assignments, opinions or other
documentation in connection therewith shall be borne by the Seller.

                  Except as expressly set forth herein neither the Trustee nor
the Master Servicer is under any obligation to discover any breach of the
above-mentioned representations and warranties.
It is understood and agreed that the obligation of the Seller to cure such
breach, purchase or to substitute for such Mortgage Loan as to which such a
breach has occurred and is continuing shall constitute the sole remedy
respecting such breach available to Certificateholders or the Trustee on behalf
of Certificateholders.

                  SECTION 2.05.             Issuance of Certificates; Conveyance
                                            of REMIC Regular Interests and
                                            Acceptance of REMIC 2 by the
                                            Trustee.

         (a) The Trustee acknowledges the assignment to it of the Mortgage Loans
and the delivery to it of the Mortgage Files, subject to the provisions of
Sections 2.01 and 2.02, together with the assignment to it of all other assets
included in the Trust Fund, receipt of which is hereby acknowledged.
Concurrently with such assignment and delivery and in exchange therefor, the
Trustee, pursuant to the written request of the Company executed by an officer
of the Company, has executed, authenticated and delivered to or upon the order
of the Company, the Certificates in authorized denominations. The interests
evidenced by the Certificates, constitute the entire beneficial ownership
interest in the Trust Fund.

         (b) The Company, concurrently with the execution and delivery hereof,

Certificates and Holders of the Class R Certificates (as holders of the Class
R-1 Interest). The Trustee acknowledges receipt of the REMIC 1 Regular Interests
(which are uncertificated) and declares that it holds and will hold the same in
trust for the exclusive use and benefit of the Holders of the Regular
Certificates and Holders of the Class R Certificates (as holders of the Class
R-1 Interest). The interests evidenced by the Class R-2 Interest, together with
the Regular Certificates, constitute the entire beneficial ownership interest in
REMIC 2.

         (c) In exchange for the REMIC 1 Regular Interests and, concurrently
with the assignment to the Trustee thereof, pursuant to the written request of
the Depositor executed by an officer of the Company, the Trustee has executed,
authenticated and delivered to or upon the order of the Company, the Regular
Certificates in authorized denominations evidencing (together with the Class R-2
Interest) the entire beneficial ownership interest in REMIC 2.

         (d) The Company, 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 Company in and
to the REMIC 2 Regular Interests for the benefit of the holders of the
Certificates. The Trustee acknowledges receipt of the REMIC 2 Regular Interests
(which are uncertificated) and declares that it holds and will hold the same in
trust for the exclusive use and benefit of the holders of the Certificates. The
interests evidenced by the Class R-3 Interest, together with the Regular
Certificates, constitute the entire beneficial ownership interest in REMIC 3.

         (e) In exchange for the REMIC 2 Regular Interests and, concurrently
with the assignment to the Trustee thereof, pursuant to the written request of
the Company executed by an officer of the Company, the Trustee has executed,
authenticated and delivered to or upon the order of the Company, the Regular
Certificates in authorized denominations evidencing (together with the Class R-3
Interest) the entire beneficial ownership interest in REMIC 3.

         (f) Concurrently with (i) the assignment and delivery to the Trustee of

                                   ARTICLE III

                          ADMINISTRATION AND SERVICING
                                OF THE TRUST FUND

                  SECTION 3.01.             Master Servicer to Act as Master
                                            Servicer.

                  The Master Servicer shall supervise, or take such actions as
are necessary to ensure, the servicing and administration of the Mortgage Loans
and any REO Property in accordance with this Agreement and its normal servicing
practices, which generally shall conform to the standards (i) of the Servicing
Guide, if Impac Funding Corporation is Master Servicer, or (ii) if Impac Funding
Corporation is not the Master Servicer, of an institution prudently servicing
mortgage loans for its own account and shall have full authority to do anything
it reasonably deems appropriate or desirable in connection with such servicing
and administration. To the extent consistent with the foregoing, the Master
Servicer 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 (ii) such waiver would, in the
reasonable judgement of the Master Servicer, maximize recovery of total proceeds
taking into account the value of such Prepayment Charge and the related Mortgage
Loan and, if such waiver is made in connection with a refinancing of the related
Mortgage Loan, such refinancing is related to a default or a reasonably
foreseeable default.

                  The Master Servicer may perform its responsibilities relating
to servicing through other agents or independent contractors, but shall not
thereby be released from any of its responsibilities as hereinafter set forth.
The authority of the Master Servicer, in its capacity as master servicer, and
any Sub-Servicer acting on its behalf, shall include, without limitation, the
power to (i) consult with and advise any Sub-Servicer regarding administration
of a related Mortgage Loan, (ii) approve any recommendation by a Sub-Servicer to
foreclose on a related Mortgage Loan, (iii) supervise the filing and collection
of insurance claims and take or cause to be taken such actions on behalf of the
insured Person thereunder as shall be reasonably necessary to prevent the denial
of coverage thereunder, and (iv) effectuate foreclosure or other conversion of
the ownership of the Mortgaged Property securing a related Mortgage Loan,
including the employment of attorneys, the institution of legal proceedings, the
collection of deficiency judgments, the acceptance of compromise proposals, the
filing of claims under any Insurance Policy and any other matter pertaining to a
delinquent Mortgage Loan. The authority of the Master Servicer shall include, in
addition, the power on behalf of the Certificateholders, the Trustee or any of
them to (i) execute and deliver customary consents or waivers and other
instruments and documents, (ii) consent to transfer of any related Mortgaged
Property and assumptions of the related Mortgage Notes and Security Instruments
(in the manner provided in this Agreement) and (iii) collect any Insurance
Proceeds and Liquidation Proceeds. Without limiting the generality of the
foregoing, the Master Servicer and any Sub-Servicer acting on its behalf may,
and is hereby authorized, and empowered by the Trustee to, execute and deliver,
on behalf of itself, the Certificateholders or the Trustee or any of them, any
instruments of satisfaction, cancellation, partial or full release, discharge
and all other comparable instruments, with respect to the related Mortgage
Loans, the Insurance Policies and the accounts


                                       50

<PAGE>



related thereto, and the Mortgaged Properties. The Master Servicer may exercise
this power in its own name or in the name of a Sub-Servicer.

                  Subject to Section 3.16, the Trustee shall execute, at the
written request of the Master Servicer, and furnish to the Master Servicer and
any Sub-Servicer such documents as are necessary or appropriate to enable the
Master Servicer or any Sub-Servicer to carry out their servicing and
administrative duties hereunder, and the Trustee hereby grants to the Master
Servicer a power of attorney to carry out such duties. The Trustee shall not be
liable for the actions of the Master Servicer or any Sub-Servicers under such
powers of attorney.

                  In accordance with the standards of the preceding paragraph,
the Master Servicer shall advance or cause to be advanced funds as necessary for
the purpose of effecting the payment of taxes and assessments on the Mortgaged
Properties, which advances shall be reimbursable in the first instance from
related collections from the Mortgagors pursuant to Section 3.09, and further as
provided in Section 3.11; provided that the Master Servicer shall not be
obligated to make such advance if, in its good faith judgment, the Master
Servicer determines that such advance to be a Nonrecoverable Advance.

                  Notwithstanding anything in this Agreement to the contrary,
the Master Servicer shall not (unless the Mortgagor is in default with respect
to the Mortgage Loan or such default is, in the judgment of the Master Servicer,
reasonably foreseeable) make or permit any modification, waiver or amendment of
any term of any Mortgage Loan that would both (i) effect an exchange or
reissuance of such Mortgage Loan under Section 1001 of the Code (or Treasury
regulations promulgated thereunder) and (ii) cause either REMIC 1, REMIC 2 or
REMIC 3 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 relationship of the Master Servicer (and of any successor
to the Master Servicer under this Agreement) to the Trustee under this Agreement
is intended by the parties to be that of an independent contractor and not that
of a joint venturer, partner or agent.

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

                  (a) The Master Servicer may enter into Sub-Servicing
Agreements with Sub- Servicers for the servicing and administration of the
Mortgage Loans and for the performance of any and all other activities of the
Master Servicer hereunder; provided, however, that such agreements would not
result in a withdrawal or a downgrading by Standard & Poor's of its rating on
any Class of Certificates. Each Sub-Servicer shall be either (i) an institution
the accounts of which are insured by the FDIC or (ii) another entity that
engages in the business of originating or servicing mortgage loans comparable to
the Mortgage Loans, and in either case shall be 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 in either case shall be a Freddie Mac or Fannie Mae


                                       51

<PAGE>



approved mortgage servicer. Any Sub-Servicing Agreement entered into by the
Master Servicer shall include the provision that such Agreement may be
immediately terminated (x) with cause and without any termination fee by any
Master Servicer hereunder or (y) without cause in which case the Master Servicer
shall be responsible for any termination fee or penalty resulting therefrom. In
addition, each Sub-Servicing Agreement shall provide for servicing of the
Mortgage Loans consistent with the terms of this Agreement. With the consent of
the Trustee, the Master Servicer and the Sub-Servicers may enter into
Sub-Servicing Agreements and make amendments to the Sub- Servicing Agreements or
enter into different forms of Sub-Servicing Agreements providing for, among
other things, the delegation by the Master Servicer to a Sub-Servicer of
additional duties regarding the administration of the Mortgage Loans; 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 51% of the Voting
Rights. The parties hereto acknowledge that the initial Sub-Servicer shall be
Wendover.

         The Master Servicer has entered into a Sub-Servicing Agreement with
Wendover for the servicing and administration of the Mortgage Loans and may
enter into additional Sub-Servicing Agreements with Sub-Servicers acceptable to
the Trustee for the servicing and administration of certain of the Mortgage
Loans.

                  (b) As part of its servicing activities hereunder, the Master
Servicer, for the benefit of the Trustee and the Certificateholders, shall
enforce the obligations of each Sub-Servicer under the related 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 Master Servicer, in its good faith business
judgment, would require were it the owner of the related Mortgage Loans. The
Master Servicer shall pay the costs of such enforcement at its own expense, but
shall be reimbursed therefor only (i) from a general recovery resulting from
such enforcement only to the extent, if any, that such recovery exceeds all
amounts due in respect of the related Mortgage Loan or (ii) from a specific
recovery of costs, expenses or attorneys' fees against the party against whom
such enforcement is directed.

                  (c) The Master Servicer represents that it has entered into a
contract regarding the sale of sub-servicing rights with respect to the Mortgage
Loans with GMAC and shall transfer the subservicing of such Mortgage Loans from
Wendover to GMAC on or about January 1, 2001.
The Trustee hereby consents to such transfer.

                  SECTION 3.03.             Successor Sub-Servicers.

                  The Master 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


                                       52

<PAGE>



simultaneously by the Master Servicer without any act or deed on the part of
such Sub-Servicer or the Master Servicer, and the Master 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.

                  SECTION 3.04.             Liability of the Master Servicer.

                  Notwithstanding any Sub-Servicing Agreement, any of the
provisions of this Agreement relating to agreements or arrangements between the
Master Servicer and a Sub-Servicer or reference to actions taken through a
Sub-Servicer or otherwise, the Master Servicer shall under all circumstances
remain obligated and primarily liable to the Trustee and Certificateholders for
the servicing and administering of the Mortgage Loans and any REO Property in
accordance with the provisions of Article III 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 Master Servicer
alone were servicing and administering the Mortgage Loans. For purposes of this
Agreement, the Master Servicer shall be deemed to have received payments on
Mortgage Loans when the Sub-Servicer has received such payments. The Master
Servicer shall be entitled to enter into any agreement with a Sub-Servicer for
indemnification of the Master 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 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 and not as an originator shall be deemed to be between
the Sub-Servicer and the Master Servicer alone, and the Trustee and
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 Master Servicer (or Sub-Servicer) shall be liable for the payment of any
franchise taxes which may be assessed by the California Franchise Tax Board in
connection with the activities of the Trust under this Agreement.

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

                  (a) If the Trustee or its designee shall assume the master
servicing obligations of the Master Servicer in accordance with Section 7.02
below, the Trustee, to the extent necessary to permit the Trustee to carry out
the provisions of Section 7.02 with respect to the Mortgage Loans, shall succeed
to all of the rights and obligations of the Master Servicer under each of the
Sub- Servicing Agreements. In such event, the Trustee or its designee as the
successor master servicer shall be deemed to have assumed all of the Master
Servicer's rights and obligations therein and to have replaced the Master
Servicer as a party to such Sub-Servicing Agreements to the same extent as if
such Sub-Servicing Agreements had been assigned to the Trustee or its designee
as a successor


                                       53

<PAGE>



master servicer, except that the Trustee or its designee as a successor master
servicer shall not be deemed to have assumed any obligations or liabilities of
the Master Servicer arising prior to such assumption (other than the obligation
to make any Advances hereunder) and the Master Servicer shall not thereby be
relieved of any liability or obligations under such Sub-Servicing Agreements
arising prior to such assumption. Nothing in the foregoing shall be deemed to
entitle the Trustee or its designee as a successor master servicer at any time
to receive any portion of the servicing compensation provided under Section 3.17
except for such portion as the Master Servicer would be entitled to receive.

                  (b) In the event that the Trustee or its designee as successor
master servicer for the Trustee assumes the servicing obligations of the Master
Servicer under Section 7.02, upon the reasonable request of the Trustee or such
designee as successor master servicer the Master Servicer shall at its own
expense deliver to the Trustee, or at its written request to such designee,
photocopies of all documents, files and records, electronic or otherwise,
relating to the Sub-Servicing Agreements and the related Mortgage Loans or REO
Property then being serviced and an accounting of amounts collected and held by
it, if any, and will otherwise cooperate and use its reasonable efforts to
effect the orderly and efficient transfer of the Sub-Servicing Agreements, or
responsibilities hereunder to the Trustee, or at its written request to such
designee as successor master servicer.

                  SECTION 3.07.             Collection of Certain Mortgage Loan
                                            Payments.

                  (a) The Master Servicer will coordinate and monitor
remittances by Sub-Servicers to the Master Servicer with respect to the Mortgage
Loans in accordance with this Agreement.

                  (b) The Master Servicer shall make its reasonable efforts to
collect or cause to be collected all payments required under the terms and
provisions of the Mortgage Loans and shall follow, and use its reasonable
efforts to cause Sub-Servicers to follow, collection procedures comparable to
the collection procedures of prudent mortgage lenders servicing mortgage loans
for their own account to the extent such procedures shall be consistent with
this Agreement. Consistent with the foregoing, the Master Servicer may in its
discretion (i) waive or permit to be waived any late payment charge, prepayment
charge, assumption fee, or any penalty interest in connection with the
prepayment of a Mortgage Loan and (ii) suspend or reduce or permit to be
suspended or reduced regular monthly payments for a period of up to six months,
or arrange or permit an arrangement with a Mortgagor for a scheduled liquidation
of delinquencies. In the event the Master Servicer shall consent to the
deferment of the due dates for payments due on a Mortgage Note, the Master
Servicer shall nonetheless make an Advance or shall cause the related
Sub-Servicer to make an advance to the same extent as if such installment were
due, owing and delinquent and had not been deferred through liquidation of the
Mortgaged Property; provided, however, that the obligation of the Master
Servicer or related Sub-Servicer to make an Advance shall apply only to the
extent that the Master Servicer believes, in good faith, that such advances are
not Nonrecoverable Advances.

                  (c) Within five Business Days after the Master Servicer has
determined that all amounts which it expects to recover from or on account of a
Mortgage Loan have been recovered and that no further Liquidation Proceeds will
be received in connection therewith, the Master


                                       54

<PAGE>



Servicer shall provide to the Trustee a certificate of a Servicing Officer that
such Mortgage Loan became a Liquidated Mortgage Loan in a Cash Liquidation or
REO Disposition as of the date of such determination.

                  The Master 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 related Insurance Policy, follow such
collection procedures as it would follow with respect to mortgage loans
comparable to the Mortgage Loans and held for its own account. The Master
Servicer shall not be required to institute or join in litigation with respect
to collection of any payment (whether under a Mortgage, Mortgage Note, Primary
Hazard Insurance Policy or otherwise or against any public or governmental
authority with respect to a taking or condemnation) if it reasonably believes
that it is prohibited by applicable law from enforcing the provision of the
Mortgage or other instrument pursuant to which such payment is required. The
Master Servicer shall be responsible for preparing and distributing all
information statements relating to payments on the Mortgage Loans, in accordance
with all applicable federal and state tax laws and regulations.

                  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
otherwise be acceptable to the Master Servicer. All amounts held in a
Sub-Servicing Account shall be held in trust for the Trustee for the benefit of
the Certificateholders. Any investment of funds held in such an account shall be
in Permitted Investments maturing not later than the Business Day immediately
preceding the next Sub-Servicer Remittance Date. The Sub- Servicer will be
required to deposit into the Sub-Servicing Account no later than the first
Business Day after receipt all proceeds of Mortgage Loans received by the
Sub-Servicer, less its servicing compensation and any unreimbursed expenses and
advances, to the extent permitted by the Sub- Servicing Agreement. On each
Sub-Servicer Remittance Date the Sub-Servicer will be required to remit to the
Master Servicer for deposit in the Custodial Account all funds held in the
Sub-Servicing Account with respect to any Mortgage Loan as of the Sub-Servicer
Remittance Date, after deducting from such remittance an amount equal to the
servicing compensation (including interest on Permitted Investments) and
unreimbursed expenses and advances to which it is then entitled pursuant to the
related Sub-Servicing Agreement, to the extent not previously paid to or
retained by it. In addition, on each Sub-Servicer Remittance Date the
Sub-Servicer will be required to remit to the Master Servicer any amounts
required to be advanced pursuant to the related Sub-Servicing Agreement. The
Sub-Servicer will also be required to remit to the Master Servicer, within one
Business Day of receipt, the proceeds of any Principal Prepayment made by the
Mortgagor and any Insurance Proceeds or Liquidation Proceeds.

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

                  The Master Servicer and the Sub-Servicers shall establish and
maintain one or more accounts (the "Servicing Accounts"), and shall deposit and
retain therein all collections from the Mortgagors (or related advances from
Sub-Servicers) for the payment of taxes, assessments, Primary Hazard Insurance
Policy premiums, and comparable items for the account of the Mortgagors, to the
extent that the Master Servicer customarily escrows for such amounts.
Withdrawals of amounts so collected from a Servicing Account may be made only to
(i) effect payment of taxes, assessments, Primary Hazard Insurance Policy
premiums and comparable items; (ii) reimburse the Master Servicer (or a
Sub-Servicer to the extent provided in the related Sub-Servicing Agreement) out
of related collections for any payments made pursuant to Sections 3.01 (with
respect to taxes and assessments), and 3.13 (with respect to Primary Hazard
Insurance Policies); (iii) refund to Mortgagors any sums as may be determined to
be overages; or (iv) clear and terminate the Servicing Account at the
termination of this Agreement pursuant to Section 9.01. As part of its servicing
duties, the Master Servicer or Sub-Servicers shall, if and to the extent
required by law, pay to the Mortgagors interest on funds in Servicing Accounts
from its or their own funds, without any reimbursement therefor.

                  SECTION 3.10.             Custodial Account.

                  (a) The Master Servicer shall establish and maintain one or
more accounts (collectively, the "Custodial Account") in which the Master
Servicer shall deposit or cause to be deposited on a daily basis, or as and when
received from the Sub-Servicers, the following payments and collections received
or made by or on behalf of it subsequent to the Cut-off Date, or received by it
prior to the Cut-off Date but allocable to a period subsequent thereto (other
than in respect of principal and interest on the Mortgage Loans due on or before
the Cut-off Date):

                (i) all payments (including advances by a Sub-Servicer) on
         account of principal, including Principal Prepayments, on the Mortgage
         Loans and all Prepayment Charges collected on the Mortgage Loans (and
         any Master Servicer Prepayment Charge Payment Amounts paid by, or
         collected on behalf of the Trust Fund by, the Master Servicer or any
         Sub-Servicer);

               (ii) all payments (including advances by a Sub-Servicer) on
         account of interest on the Mortgage Loans, including Buydown Funds, if
         any, net of any portion thereof retained by the Master Servicer or any
         Sub-Servicer as Servicing Fees;

              (iii) all Insurance Proceeds, other than proceeds that represent
         reimbursement of costs and expenses incurred by the Master Servicer or
         any Sub-Servicer in connection with presenting claims under the related
         Insurance Policies, Liquidation Proceeds and REO
         Proceeds;



                                       56

<PAGE>



               (iv) all proceeds of any Mortgage Loan or REO Property
         repurchased or purchased in accordance with Sections 2.02, 2.04 , 3.14,
         3.24 or 9.01; and all amounts required to be deposited in connection
         with the substitution of a Qualified Substitute Mortgage Loan pursuant
         to Section 2.04; and

                (v) any amounts required to be deposited pursuant to Section
         3.12, 3.13, 3.15 or 3.22.

                  The foregoing requirements for deposit in the Custodial
Account shall be exclusive. In the event the Master Servicer shall deposit in
the Custodial Account any amount not required to be deposited therein, it may
withdraw such amount from the Custodial Account, any provision herein to the
contrary notwithstanding. The Custodial Account shall be maintained as a
segregated account, separate and apart from trust funds created for mortgage
pass-through certificates of other series, and the other accounts of the Master
Servicer.

                  (b) Funds in the Custodial Account may be invested in
Permitted Investments in accordance with the provisions set forth in Section
3.12. The Master Servicer shall give notice to the Trustee and the Company of
the location of the Custodial Account after any change thereof.

                  SECTION 3.11.             Permitted Withdrawals From the
                                            Custodial Account.

                  The Master Servicer may, from time to time as provided herein,
make withdrawals from the Custodial Account of amounts on deposit therein
pursuant to Section 3.10 that are attributable to the Mortgage Loans for the
following purposes:

                         (i) to make deposits into the Certificate Account in
         the amounts and in the manner provided for in Section 4.01;

                        (ii) to pay to itself, the Company, the Seller or any
         other appropriate person, as the case may be, with respect to each
         Mortgage Loan that has previously been purchased or repurchased
         pursuant to Sections 2.02, 2.04, 3.14, 3.24 or 9.01 all amounts
         received thereon and not yet distributed as of the date of purchase or
         repurchase;

                       (iii) to reimburse itself or any Sub-Servicer for
         Advances not previously reimbursed, the Master Servicer's or any
         Sub-Servicer's right to reimbursement pursuant to this clause (iii)
         being limited to amounts received which represent Late Collections (net
         of the related Servicing Fees) of Monthly Payments on Mortgage Loans
         with respect to which such Advances were made and as further provided
         in Section 3.15;

                        (iv) to reimburse or pay itself, the Trustee or the
         Company for expenses incurred by or reimbursable to the Master
         Servicer, the Trustee or the Company pursuant to Sections 3.22, 6.03,
         8.05 or 10.01(g), except as otherwise provided in such Sections
         hereof;



                                       57

<PAGE>



                         (v) to reimburse itself or any Sub-Servicer for costs
         and expenses incurred by or reimbursable to it relating to the
         prosecution of any claims pursuant to Section 3.13 that are in excess
         of the amounts so recovered;

                        (vi) to reimburse itself or any Sub-Servicer for unpaid
         Servicing Fees and unreimbursed Servicing Advances, the Master
         Servicer's or any Sub-Servicer's right to reimbursement pursuant to
         this clause (vi) with respect to any Mortgage Loan being limited to
         late recoveries of the payments for which such advances were made
         pursuant to Section 3.01 or Section 3.09 and any other related Late
         Collections;

                       (vii) to pay itself as servicing compensation (in
         addition to the Servicing Fee), on or after each Distribution Date, any
         interest or investment income earned on funds deposited in the
         Custodial Account for the period ending on such Distribution Date;

                      (viii) to reimburse itself or any Sub-Servicer for any
         Advance or Servicing Advance previously made, after a Realized Loss has
         been allocated with respect to the related Mortgage Loan if the Advance
         or Servicing Advance was not reimbursed pursuant to clauses (iii) and
         (vi);

                         (ix) to pay Radian the premium under the Radian
         Lender-Paid PMI Policies; and

                         (x) to clear and terminate the Custodial Account at the
         termination of this Agreement pursuant to Section 9.01.

                  The Master Servicer shall keep and maintain separate
accounting records on a Mortgage Loan by Mortgage Loan basis, for the purpose of
justifying any withdrawal from the Custodial Account pursuant to such subclauses
(ii) through (ix).

                  SECTION 3.12.             Permitted Investments.

                  Any institution maintaining the Custodial Account shall at the
direction of the Master Servicer invest the funds in such account in Permitted
Investments, each of which shall mature not later than (i) 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 Trustee
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
Trustee is the obligor thereon and shall not be sold or disposed of prior to its
maturity. All income and gain realized from any such investment as well as any
interest earned on deposits in the Custodial Account shall be for the benefit of
the Master Servicer. The Master Servicer shall deposit in the Custodial Account
an amount equal to the amount of any loss incurred in respect of any such
investment immediately upon realization of such loss without right of
reimbursement.

                  SECTION 3.13.             Maintenance of Primary Hazard
                                            Insurance.

                  (a) The Master Servicer shall cause to be maintained for each
Mortgage Loan primary hazard insurance by a Qualified Insurer or other insurer
satisfactory to the Rating Agencies with extended coverage on the related
Mortgaged Property in an amount equal to the lesser of (i) 100% of the
replacement value of the improvements, as determined by the insurance company,
on such Mortgaged Property or (ii) the unpaid principal balance of the Mortgage
Loan. The Master Servicer shall also cause to be maintained on property acquired
upon foreclosure, or deed in lieu of foreclosure, of any Mortgage Loan, fire
insurance with extended coverage in an amount equal to the replacement value of
the improvements thereon. Any costs incurred in maintaining any insurance
described in this Section 3.13 (other than any deductible described in the last
paragraph hereof) shall be recoverable as a Servicing Advance. The Master
Servicer shall not be obligated to advance any amounts pursuant to this Section
3.13 if, in its good faith judgment, the Master Servicer determines that such
advance would be a Nonrecoverable Advance. Pursuant to Section 3.10, any amounts
collected by the Master Servicer under any such policies (other than amounts to
be applied to the restoration or repair of the related Mortgaged Property or
property thus acquired or amounts released to the Mortgagor in accordance with
the Master Servicer's normal servicing procedures) shall be deposited in the
Custodial Account, subject to withdrawal pursuant to Section 3.11. Any cost
incurred by the Master Servicer in maintaining any such insurance shall not, for
the purpose of calculating monthly distributions to Certificateholders, be added
to the amount owing under the Mortgage Loan, notwithstanding that the terms of
the Mortgage Loan so permit. It is understood and agreed that no earthquake or
other additional insurance is to be required of any Mortgagor or maintained on
property acquired in respect of a Mortgage Loan other than pursuant to such
applicable laws and regulations as shall at any time be in force and as shall
require such additional insurance.

                  The Master Servicer shall, or shall cause the related
Sub-Servicer to, exercise its best reasonable efforts to maintain and keep in
full force and effect each Primary Insurance Policy by a Qualified Insurer, or
other insurer satisfactory to the Rating Agencies, with respect to each first
lien Mortgage Loan as to which as of the Cut-Off Date such a Primary Insurance
Policy was in effect (or, in the case of a Qualified Substitute Mortgage Loan,
the date of substitution) and the original principal amount of the related
Mortgage Note exceeded 80% of the Collateral Value in an amount at least equal
to the excess of such original principal amount over 75% of such Collateral
Value until the principal amount of any such first lien Mortgage Loan is reduced
below 80% of the Collateral Value or, based upon a new appraisal, the principal
amount of such first lien Mortgage Loan represents less than 80% of the new
appraised value. The Master Servicer shall, or shall cause the related
Sub-Servicer to, effect the timely payment of the premium on each Primary
Insurance Policy. The Master Servicer and the related Sub-Servicer shall have
the power to substitute for any Primary Insurance Policy another substantially
equivalent policy issued by another Qualified Insurer, provided, that, such
substitution shall be subject to the condition that it will not cause the
ratings on the Certificates to be downgraded or withdrawn, as evidenced in
writing from each Rating Agency.



                                       59

<PAGE>



          The Master Servicer shall cooperate with Radian and shall use its best
efforts to furnish all reasonable aid, evidence and information in the
possession of the Master Servicer or to which the Master Servicer has access
with respect to any Radian Insured Loan.

         In the event of a default by Radian under the Radian Lender-Paid PMI
Policy (a "Replacement Event"), the Master Servicer shall use its best efforts
to obtain a substitute lender-paid primary mortgage insurance policy (a
"Substitute PMI Policy"); PROVIDED, HOWEVER, that (i) the Certificates shall be
rated no lower than the rating assigned by each Rating Agency to the
Certificates immediately prior to such Replacement Event, as evidenced by a
letter from each Rating Agency addressed to the Company, the Master Servicer and
the Trustee, (ii) the timing and mechanism for drawing on such new Substitute
PMI Policy shall be reasonably acceptable to the Master Servicer and the Trustee
and (iii) the premiums under the proposed Substitute PMI Policy not exceed such
premiums under the existing Radian Lender-Paid PMI Policy.

         With respect to the Radian PMI Insured Loans covered by a Radian
Lender-Paid PMI Policy, the Master Servicer will confirm with Radian, and Radian
will certify to the Trustee, on or before January 15, 2001, that the Mortgage
Loans indicated on the Mortgage Loan Schedule as being covered by Radian
Lender-Paid PMI Policy are so covered.

         No earthquake or other additional insurance is to be required of any
Mortgagor or maintained on property acquired with respect to a security
instrument other than pursuant to such applicable laws and regulations as shall
at any time be in force and shall require such additional insurance. When, at
the time of origination of the Mortgage Loan or at any subsequent time, the
Mortgaged Property is located in a federally designated special flood hazard
area, the Master Servicer shall cause with respect to the Mortgage Loans and
each REO Property flood insurance (to the extent available and in accordance
with mortgage servicing industry practice) to be maintained. Such flood
insurance shall cover the Mortgaged Property, including all items taken into
account in arriving at the Collateral Value on which the Mortgage Loan was
based, and shall be in an amount equal to the lesser of (i) the Stated Principal
Balance of the related Mortgage Loan and (ii) the minimum amount required under
the terms of coverage to compensate for any damage or loss on a replacement cost
basis, but not more than the maximum amount of such insurance available for the
related Mortgaged Property under either the regular or emergency programs of the
National Flood Insurance Program (assuming that the area in which such Mortgaged
Property is located is participating in such program). Unless applicable state
law requires a higher deductible, the deductible on such flood insurance may not
exceed $1,000 or 1% of the applicable amount of coverage, whichever is less.

                  In the event that the Master Servicer shall obtain and
maintain a blanket fire insurance policy with extended coverage 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 3.13, it being understood and agreed that such policy may contain a
deductible clause, in which case the Master Servicer shall, in the event that
there shall not have been maintained on the related Mortgaged Property a policy
complying with the first two sentences of this Section 3.13 and there shall have
been a loss which would have been covered by such policy, deposit in the
Certificate Account from its own funds the amount not otherwise payable under
the blanket policy because of


                                       60

<PAGE>



such deductible clause. Any such deposit by the Master Servicer shall be made on
the Certificate Account Deposit Date next preceding the Distribution Date which
occurs in the month following the month in which payments under any such policy
would have been deposited in the Custodial Account. Any such deposit shall not
be deemed Servicing Advances and the Master Servicer shall not be entitled to
reimbursement therefor. In connection with its activities as administrator and
servicer of the Mortgage Loans, the Master Servicer agrees to present, on behalf
of itself, the Trustee and Certificateholders, claims under any such blanket
policy.

                  SECTION 3.14.             Enforcement of Due-on-Sale Clauses;
                                            Assumption Agreements.

                  The Master Servicer will, to the extent it has knowledge of
any conveyance or prospective conveyance by any Mortgagor of the Mortgaged
Property (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 or the
Mortgage), exercise or cause to be exercised its rights to accelerate the
maturity of such Mortgage Loan under any "due-on-sale" clause applicable
thereto; provided, however, that the Master Servicer shall not exercise any such
rights if it reasonably believes that it is prohibited by law from doing so. The
Master Servicer or the related Sub-Servicer may repurchase a Mortgage Loan at
the Purchase Price when the Master Servicer requires acceleration of the
Mortgage Loan, but only if the Master Servicer is satisfied, as evidenced by an
Officer's Certificate delivered to the Trustee, that either (i) such Mortgage
Loan is in default or default is reasonably foreseeable or (ii) if such Mortgage
Loan is not in default or default is not reasonably foreseeable, such repurchase
will have no adverse tax consequences for the Trust Fund or any
Certificateholder.
If the Master Servicer is unable to enforce such "due-on-sale" clause (as
provided in the second preceding sentence) or if no "due-on-sale" clause is
applicable, the Master Servicer or the Sub- Servicer is authorized to enter into
an assumption and modification agreement 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; provided, however,
that the Master Servicer shall not enter into any assumption and modification
agreement if the coverage provided under the Primary Insurance Policy, if any,
would be impaired by doing so. The Master Servicer shall notify the Trustee,
whenever possible, before the completion of such assumption agreement, and shall
forward to the Trustee the original copy of such assumption agreement, which
copy shall be added by the Trustee to the related Mortgage File and which 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.
In connection with any such assumption agreement, the interest rate on the
related Mortgage Loan shall not be changed and no other material alterations in
the Mortgage Loan shall be made unless such material alteration would not cause
either REMIC 1, REMIC 2 or REMIC 3 to fail to qualify as a REMIC for federal
income tax purposes, as evidenced by an Opinion of Counsel. The Master 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. Any fee collected by or on behalf of the Master Servicer for
entering into an assumption or substitution of liability agreement will be
retained by or on behalf of the Master Servicer as additional servicing
compensation. In connection


                                       61

<PAGE>



with any such assumption, no material term of the Mortgage Note (including but
not limited to the Mortgage Rate, the amount of the Monthly Payment and any
other term affecting the amount or timing of payment on the Mortgage Loan) may
be changed. The Master Servicer shall not enter into any substitution or
assumption if such substitution or assumption shall (i) both constitute a
"significant modification" effecting an exchange or reissuance of such Mortgage
Loan under the Code (or Treasury regulations promulgated thereunder) and cause
either REMIC 1, REMIC 2 or REMIC 3 to fail to qualify as a REMIC under the REMIC
Provisions or (ii) cause the imposition of any tax on "prohibited transactions"
or "contributions" after the Startup Day under the REMIC Provisions. The Master
Servicer shall notify the Trustee that any such substitution or assumption
agreement has been completed by forwarding to the Trustee the original copy of
such substitution or assumption agreement, which copy 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. A portion equal to up to 2% of the Collateral Value
of the related Mortgage Loan, of any fee or additional interest collected by the
related Sub-Servicer for consenting in any such conveyance or entering into any
such assumption agreement may be retained by the related Sub-Servicer as
additional servicing compensation.

                  Notwithstanding the foregoing paragraph or any other provision
of this Agreement, the Master 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 any assumption that the
Master Servicer may be restricted by law from preventing, for any reason
whatsoever. For purposes of this Section 3.14, the term "assumption" is deemed
to also include a sale of a Mortgaged Property that is not accompanied by an
assumption or substitution of liability agreement.

                  SECTION 3.15.             Realization Upon Defaulted Mortgage
                                            Loans.

                  The Master Servicer shall exercise reasonable efforts,
consistent with the procedures that the Master Servicer would use in servicing
loans for its own account, to foreclose upon or otherwise comparably convert
(which may include an REO Acquisition) 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, and which are not released from the Trust Fund
pursuant to any other provision hereof. The Master Servicer shall use reasonable
efforts to realize proceeds from such defaulted Mortgage Loans in such manner
(including short sales) as will maximize the receipt of principal and interest
by Certificateholders, taking into account, among other things, the timing of
foreclosure proceedings. The foregoing is subject to the provisions that, in any
case in which Mortgaged Property shall have suffered damage from an Uninsured
Cause, the Master Servicer shall not be required to expend its own funds toward
the restoration of such property unless it shall determine in its sole
discretion (i) that such restoration will increase the net proceeds of
liquidation of the related Mortgage Loan to Certificateholders after
reimbursement to itself for such expenses, and (ii) that such expenses will be
recoverable by the Master Servicer through Insurance Proceeds or Liquidation
Proceeds from the related Mortgaged Property, as contemplated in Section 3.11.
The Master Servicer shall be responsible for all other costs and expenses
incurred by it in any such proceedings; provided,


                                       62

<PAGE>



however, that it shall be entitled to reimbursement thereof from the related
property, as contemplated in Section 3.11.

                  The proceeds of any Cash Liquidation or REO Disposition, as
well as any recovery resulting from a partial collection of Insurance Proceeds
or Liquidation Proceeds or any income from an REO Property, will be deposited
into the Custodial Account and applied in the following order of priority:
first, to reimburse the Master Servicer or any Sub-Servicer for any related
unreimbursed Servicing Advances, pursuant to Section 3.11(vi) or 3.22; second,
to accrued and unpaid interest on the Mortgage Loan or REO Imputed Interest, at
the Mortgage Rate, to the date of the Cash Liquidation or REO Disposition, or to
the Due Date prior to the Distribution Date on which such amounts are to be
distributed if not in connection with a Cash Liquidation or REO Disposition; and
third, as a recovery of principal of the Mortgage Loan. If the amount of the
recovery so allocated to interest is less than a full recovery thereof, that
amount will be allocated as follows: first, to unpaid Servicing Fees; and
second, to interest at the Net Mortgage Rate. The portion of the recovery so
allocated to unpaid Servicing Fees shall be reimbursed to the Master Servicer or
any Sub-Servicer pursuant to Section 3.11(vi). The portions of the recovery so
allocated to interest at the Net Mortgage Rate and to principal of the Mortgage
Loan shall be applied as follows: first, to reimburse the Master Servicer or any
Sub-Servicer for any related unreimbursed Advances in accordance with Section
3.11(iii) or 3.22, and second, for distribution in accordance with the
provisions of Section 4.01, subject to Section 3.22 with respect to certain
recoveries from an REO Disposition constituting Excess Proceeds.

                  SECTION 3.16.             Trustee to Cooperate; Release of
                                            Mortgage Files.

                  Upon the payment in full of any Mortgage Loan, or the receipt
by the Master Servicer of a notification that payment in full shall be escrowed
in a manner customary for such purposes, the Master Servicer will immediately
notify the Trustee by a certification (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 Custodial
Account pursuant to Section 3.10 have been or will be so deposited) of a
Servicing Officer and shall request delivery to it of the Mortgage File in the
form of the Request for Release attached hereto as Exhibit F-2. Upon receipt of
such certification and request, the Trustee shall promptly release the related
Mortgage File to the Master Servicer. Subject to the receipt by the Master
Servicer of the proceeds of such payment in full and the payment of all related
fees and expenses, the Master Servicer shall arrange for the release to the
Mortgagor of the original canceled Mortgage Note. All other documents in the
Mortgage File shall be retained by the Master Servicer to the extent required by
applicable law. The Master Servicer shall provide for preparation of the
appropriate instrument of satisfaction covering any Mortgage Loan which pays in
full and the Trustee shall cooperate in the execution and return of such
instrument to provide for its delivery or recording as may be required. No
expenses incurred in connection with any instrument of satisfaction or deed of
reconveyance shall be chargeable to the Custodial Account or the Certificate
Account.

                  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


                                       63

Loan, the Trustee shall, upon request of the Master Servicer and delivery to the
Trustee of a Request for Release in the form attached hereto as Exhibit F-1,
release the related Mortgage File to the Master Servicer and the Trustee shall
execute such documents as the Master Servicer shall prepare and request as being
necessary to the prosecution of any such proceedings. Such Request for Release
shall obligate the Master Servicer to return each document previously requested
from the Mortgage File to the Trustee when the need therefor by the Master
Servicer no longer exists; and in any event within 21 days of the Master
Servicer's receipt thereof, unless the Mortgage Loan has been liquidated and the
Liquidation Proceeds relating to the Mortgage Loan have been deposited in the
Custodial 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 Master Servicer has delivered to 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 Request for Release stating that such Mortgage Loan
was liquidated and that all amounts received or to be received in connection
with such liquidation which are required to be deposited into the Custodial
Account have been or will be so deposited, or that such Mortgage Loan has become
an REO Property, a copy of the Request for Release shall be released by the
Trustee to the Master Servicer.

                  Upon written request of a Servicing Officer, the Trustee shall
execute and deliver to the Master Servicer any court pleadings, requests for
trustee's sale or other documents prepared by the Master Servicer that are
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 request that such
pleadings or documents be executed by the Trustee shall include a certification
signed by a Servicing Officer 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 3.17.             Servicing Compensation.

                  As compensation for its activities hereunder, the Master
Servicer shall be entitled to withhold and retain, from deposits to the
Custodial Account of amounts representing payments or recoveries of interest,
the Servicing Fees with respect to each Mortgage Loan (less any portion of such
amounts retained by any Sub-Servicer). In addition, the Master Servicer shall be
entitled to recover unpaid Servicing Fees out of related Late Collections to the
extent permitted in Section 3.11.

                  The Master Servicer also shall be entitled pursuant to Section
3.11 to receive from the Custodial Account as additional servicing compensation
interest or other income earned on deposits therein, subject to Section 3.23, as
well as any assumption fees, late payment charges and reconveyance fees. The
Master Servicer shall not be entitled to retain any Prepayment Charges. The
Master Servicer shall be required to pay all expenses incurred by it in
connection with its servicing


                                       64

<PAGE>



activities hereunder (including payment of the premiums for any blanket policy
insuring against hazard losses pursuant to Section 3.13 and servicing
compensation of the Sub-Servicer to the extent not retained by it), and shall
not be entitled to reimbursement therefor except as specifically provided in
Section 3.11. The Servicing Fee may not be transferred in whole or in part
except in connection with the transfer of all of the Master Servicer's
responsibilities and obligations under this Agreement.

                  SECTION 3.18.             Maintenance of Certain Servicing
                                            Policies.

         The Master Servicer shall obtain and maintain at its own expense and
shall cause each Sub- Servicer to obtain and maintain for the duration of this
Agreement a blanket fidelity bond and an errors and omissions insurance policy
covering the Master Servicer's and such Sub-Servicer's officers, employees and
other persons acting on its behalf in connection with its activities under this
Agreement. The amount of coverage shall be at least equal to the coverage
maintained by the Master Servicer or Sub-Servicer in order to be acceptable to
Fannie Mae or Freddie Mac to service loans for it or otherwise in an amount as
is commercially available at a cost that is generally not regarded as excessive
by industry standards. The Master Servicer shall promptly notify the Trustee in
writing of any material change in the terms of such bond or policy. The Master
Servicer shall provide annually to the Trustee a certificate of insurance that
such bond and policy are in effect. If any such bond or policy ceases to be in
effect, the Master Servicer shall, to the extent possible, give the Trustee ten
days' notice prior to any such cessation and shall use its reasonable best
efforts to obtain a comparable replacement bond or policy, as the case may be.

                  SECTION 3.19.             Annual Statement as to Compliance.

                  Within 120 days after December 31 of each year, commencing on
the first December 31 following the first anniversary of the Closing Date, the
Master Servicer at its own expense shall deliver to the Trustee, with a copy to
the Rating Agencies, a certificate signed by a Servicing Officer stating, as to
the signers thereof, that (i) a review of the activities of the Master Servicer
during the preceding calendar year and of performance under this Agreement has
been made under such officers' supervision, (ii) to the best of such officers'
knowledge, based on such review, the Master Servicer has fulfilled all its
obligations under this Agreement for such year, or, if there has been a default
in the fulfillment of any such obligation, specifying each such default known to
such officer and the nature and status thereof including the steps being taken
by the Master Servicer to remedy such default; (iii) a review of the activities
of each Sub-Servicer during the Sub-Servicer's most recently ended fiscal year
on or prior to such December 31 and its performance under its Sub- Servicing
Agreement has been made under such officer's supervision; and (iv) to the best
of the Servicing Officer's knowledge, based on his review and the certification
of an officer of the Sub- Servicer (unless the Servicing Officer has reason to
believe that reliance on such certification is not justified), either each
Sub-Servicer has performed and fulfilled its duties, responsibilities and
obligations under this Agreement and its Sub-Servicing Agreement in all material
respects throughout the year, or, if there has been a default in performance or
fulfillment of any such duties, responsibilities or obligations, specifying the
nature and status of each such default known to the Servicing Officer. Copies of
such statements shall be provided by the Master Servicer to the


                                       65

<PAGE>



Certificateholders upon request or by the Trustee at the expense of the Master
Servicer should the Master Servicer fail to provide such copies.

                  SECTION 3.20.             Annual Independent Public
                                            Accountants' Servicing Statement.

                  (a) Within 120 days after December 31 of each year, commencing
on the first December 31 following the first anniversary of the Closing Date,
the Master Servicer, at its expense, shall cause a firm of independent public
accountants who are members of the American Institute of Certified Public
Accountants to furnish a statement to the Master Servicer, which will be
provided to the Trustee and the Rating Agencies, to the effect that, in
connection with the firm's examination of the Master Servicer's financial
statements as of the end of such calendar year, nothing came to their attention
that indicated that the Master Servicer was not in compliance with the
provisions of this Agreement except for (i) such exceptions as such firm
believes to be immaterial and (ii) such other exceptions as are set forth in
such statement.

                  (b) Within 120 days after December 31 of each year, commencing
December 2001, the Master Servicer, at its expense, shall or shall cause each
Sub-Servicer to cause a nationally recognized firm of independent certified
public accountants to furnish to the Master Servicer or such Sub-Servicer a
report stating that (i) it has obtained a letter of representation regarding
certain matters from the management of the Master Servicer or such Sub-Servicer
which includes an assertion that the Master Servicer or such Sub-Servicer has
complied with certain minimum mortgage loan servicing standards (to the extent
applicable to commercial and multifamily mortgage loans) identified in the
Uniform Single Attestation Program for Mortgage Bankers established by the
Mortgage Bankers Association of America with respect to the servicing of first
and second lien conventional single family mortgage loans during the most
recently completed calendar year and (ii) on the basis of an examination
conducted by such firm in accordance with standards established by the American
Institute of Certified Public Accountants, such representation is fairly stated
in all material respects, subject to such exceptions and other qualifications
that may be appropriate. Immediately upon receipt of such report, the Master
Servicer shall or shall cause each Sub-Servicer to furnish a copy of such report
to the Trustee and the Rating Agencies.

                  SECTION 3.21.             Access to Certain Documentation.

                  The Master Servicer shall provide, and shall cause any
Sub-Servicer to provide, to the Trustee, access to the documentation in their
possession regarding the related Mortgage Loans and REO Properties and to the
Certificateholders, the FDIC, and the supervisory agents and examiners of the
FDIC (to which the Trustee shall also provide) access to the documentation
regarding the related Mortgage Loans required by applicable regulations, such
access being afforded without charge but only upon reasonable request and during
normal business hours at the offices of the Master Servicer or the Sub-Servicers
that are designated by these entities; provided, however, that, unless otherwise
required by law, the Trustee, the Master Servicer or the Sub-Servicer shall not
be required to provide access to such documentation if the provision thereof
would violate the legal right to privacy of any Mortgagor; provided, further,
however, that the Trustee shall coordinate its


                                       66

<PAGE>



requests for such access so as not to impose an unreasonable burden on, or cause
an unreasonable interruption of, the business of the Master Servicer or any
Sub-Servicer. The Master Servicer, the Sub-Servicers and the Trustee shall allow
representatives of the above entities to photocopy any of the documentation and
shall provide equipment for that purpose at a charge that covers their own
actual out-of-pocket costs.

                  SECTION 3.22.             Title, Conservation and Disposition
                                            of REO Property.

                  This Section shall apply only to REO Properties acquired for
the account of REMIC 1 and shall not apply to any REO Property relating to a
Mortgage Loan which was purchased or repurchased from REMIC 1 pursuant to
Sections 2.02, 2.04, 3.14 or 3.24. In the event that title to any such REO
Property is acquired, the deed or certificate of sale shall be issued to the
Trustee, or to its nominee, on behalf of the Certificateholders. The Master
Servicer, on behalf of REMIC 1, shall either sell any REO Property before the
close of the third taxable year following the taxable year in which REMIC 1
acquires ownership of such REO Property for purposes of Section 860G(a)(8) of
the Code or, at the expense of REMIC 1, request, more than 60 days before the
day on which the three-year grace period would otherwise expire an extension of
the three-year grace period, unless the Master Servicer has delivered to the
Trustee an Opinion of Counsel (which shall not be at the expense of the
Trustee), addressed to the Trustee and the Master Servicer, to the effect that
the holding by REMIC 1 of such REO Property subsequent to the close of the third
taxable year following the taxable year in which REMIC 1 acquires ownership of
such REO Property will not result in the imposition on REMIC 1 of taxes on
"prohibited transactions" thereof, as defined in Section 860F of the Code, or
cause either REMIC 1, REMIC 2 or REMIC 3 to fail to qualify as a REMIC under the
REMIC Provisions or comparable provisions of the laws of the State of California
at any time that any Certificates are outstanding. The Master Servicer shall
manage, conserve, protect and operate each REO Property for the
Certificateholders solely for the purpose of its prompt disposition and sale in
a manner which does not cause such REO Property to fail to qualify as
"foreclosure property" within the meaning of Section 860G(a)(8) or result in the
receipt by either REMIC 1, REMIC 2 or REMIC 3 of any "income from non-permitted
assets" within the meaning of Section 860F(a)(2)(B) of the Code or any "net
income from foreclosure property" which is subject to taxation under the REMIC
Provisions. Pursuant to its efforts to sell such REO Property, the Master
Servicer shall either itself or through an agent selected by the Master Servicer
protect and conserve such REO Property in the same manner and to such extent as
is customary in the locality where such REO Property is located and may,
incident to its conservation and protection of the interests of the
Certificateholders, rent the same, or any part thereof, as the Master Servicer
deems to be in the best interest of the Certificateholders for the period prior
to the sale of such REO Property.

                  Any REO Disposition shall be for cash only (unless changes in
the REMIC Provisions made subsequent to the Startup Day allow a sale for other
consideration).

                  The Master Servicer shall segregate and hold all funds
collected and received in connection with the operation of any REO Property
separate and apart from its own funds and general assets. The Master Servicer
shall deposit, or cause to be deposited, on a daily basis in the


                                       67

<PAGE>



Custodial Account all revenues received with respect to the REO Properties, net
of any directly related expenses incurred or withdraw therefrom funds necessary
for the proper operation, management and maintenance of the REO Property.

                  If as of the date of acquisition of title to any REO Property
there remain outstanding unreimbursed Servicing Advances with respect to such
REO Property or any outstanding Advances allocated thereto the Master Servicer,
upon an REO Disposition, shall be entitled to reimbursement for any related
unreimbursed Servicing Advances and any unreimbursed related Advances as well as
any unpaid Servicing Fees from proceeds received in connection with the REO
Disposition, as further provided in Section 3.15. The Master Servicer shall not
be obligated to advance any amounts with respect to an REO Property if, in its
good faith judgment, the Master Servicer determines that such advance would
constitute a Nonrecoverable Advance.

                  The REO Disposition shall be carried out by the Master
Servicer at such price and upon such terms and conditions as the Master Servicer
shall determine.

                  The Master Servicer shall deposit the proceeds from the REO
Disposition, net of any payment to the Master Servicer as provided above, in the
Custodial Account upon receipt thereof for distribution in accordance with
Section 4.01; provided, that any such net proceeds received by the Master
Servicer which are in excess of the applicable Stated Principal Balance plus all
unpaid REO Imputed Interest thereon through the last day of the month in which
the REO Disposition occurred ("Excess Proceeds") shall be retained by the Master
Servicer as additional servicing compensation.

                  With respect to any Mortgage Loan as to which the Master
Servicer has received notice of, or has actual knowledge of, the presence of any
toxic or hazardous substance on the Mortgaged Property, the Master Servicer
shall not, on behalf of the Trustee, either (i) obtain title to the related
Mortgaged Property as a result of or in lieu of foreclosure or otherwise, or
(ii) otherwise acquire possession of, the related Mortgaged Property, unless the
Master Servicer has, at least 30 days prior to taking such action, obtained and
delivered to the Trustee an environmental audit report prepared by a Person who
regularly conducts environmental audits using customary industry standards. The
Master Servicer shall take such action as it deems to be in the best economic
interest of the Trust Fund (other than proceeding against the Mortgaged
Property) and is hereby authorized at such time as it deems appropriate to
release such Mortgaged Property from the lien of the related Mortgage.

                  The cost of the environmental audit report contemplated by
this Section 3.22 shall be advanced by the Master Servicer as an expense of the
Trust Fund, and the Master Servicer shall be reimbursed therefor from the
Custodial Account as provided in Section 3.11, any such right of reimbursement
being prior to the rights of the Certificateholders to receive any amount in the
Custodial Account.

                  If the Master 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


                                       68

<PAGE>



in 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 Master 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, clean-up or remediation shall be advanced by the
Master Servicer as an expense of the Trust Fund, and the Master Servicer shall
be entitled to be reimbursed therefor from the Custodial Account as provided in
Section 3.11, any such right of reimbursement being prior to the rights of the
Certificateholders to receive any amount in the Custodial Account.

                  SECTION 3.23.             Additional Obligations of the Master
                                            Servicer.

                  On each Certificate Account Deposit Date, the Master Servicer
shall deliver to the Trustee for deposit in the Certificate Account from its own
funds and without any right of reimbursement therefor, a total amount equal to
the amount of Compensating Interest for the related Distribution Date.

                  SECTION 3.24              Optional Purchase of Defaulted
                                            Mortgage Loans.

         The Master Servicer or any affiliate of the Master Servicer, in its
sole discretion, shall have the right to elect (by written notice sent to the
Master Servicer, and the Trustee), but shall not be obligated, to purchase for
its own account from the Trust Fund any Mortgage Loan which is 90 days or more
delinquent in the manner and at the price specified in Section 2.04. The
purchase price for any Mortgage Loan purchased hereunder shall be deposited in
the Certificate Account and the Trustee, upon receipt of such deposit, shall
release or cause to be released to the purchaser of such Mortgage Loan the
related Mortgage File and shall execute and deliver such instruments of transfer
or assignment prepared by the purchaser of such Mortgage Loan, in each case
without recourse, as shall be necessary to vest in the purchaser of such
Mortgage Loan any Mortgage Loan released pursuant hereto and the purchaser of
such Mortgage Loan shall succeed to all the Trustee's right, title and interest
in and to such Mortgage Loan and all security and documents related thereto.
Such assignment shall be an assignment outright and not for security. The
purchaser of such Mortgage Loan shall thereupon own such Mortgage Loan, and all
security and documents, free of any further obligation to the Trustee or the
Certificateholders with respect thereto. Notwithstanding the foregoing, the
Trustee, whether acting as Trustee or in the capacity of successor Master
Servicer, shall have no obligation to repurchase any Mortgage Loan.

                  SECTION 3.25.             Additional Obligations of the
                                            Company.

                  The Company agrees that on or prior to the tenth day after the
Closing Date, the Company shall provide the Trustee with a written notification,
substantially in the form of Exhibit J attached hereto, relating to each Class
of Certificates, setting forth (i) in the case of each Class of such
Certificates, (a) if less than 10% of the aggregate Certificate Principal
Balance or Notional Amount of such Class of Certificates has been sold as of
such date, the value calculated pursuant to clause (b)(iii) of Exhibit J hereto,
or, (b) if 10% or more of such Class of Certificates has been sold as of such
date but no single price is paid for at least 10% of the aggregate Certificate
Principal


                                       69

<PAGE>



Balance or Notional Amount of such Class of Certificates, then the weighted
average price at which the Certificates of such Class were sold and the
aggregate percentage of Certificates of such Class sold, (c) the first single
price at which at least 10% of the aggregate Certificate Principal Balance or
Notional Amount of such Class of Certificates was sold, or (d) if any
Certificates of each Class of Certificates are retained by the Company or an
affiliate corporation, or are delivered to the Seller, the fair market value of
such Certificates as of the Closing Date, (ii) the Prepayment Assumption used in
pricing the Certificates, and (iii) such other information as to matters of fact
as the Trustee may reasonably request to enable it to comply with its reporting
requirements with respect to each Class of such Certificates to the extent such
information can in the good faith judgment of the Company be determined by it.

                  SECTION 3.26.             Periodic Filings with the Securities
                                            and Exchange Commission; Additional
                                            Information.

                  The Trustee shall prepare or cause to be prepared for filing
with the Commission any and all reports, statements and information respecting
the Trust Fund and/or the Certificates required to be filed with the Commission
pursuant to the Securities Exchange Act of 1934, as amended, and shall solicit
any and all proxies of the Certificateholders whenever such proxies are required
to be solicited, pursuant to the Securities Exchange Act of 1934, as amended.
The Company shall promptly file, and exercise its reasonable best efforts to
obtain a favorable response to, no-action requests with, or other appropriate
exemptive relief from, the Commission seeking the usual and customary exemption
from such reporting requirements granted to issuers of securities similar to the
Certificates. Fees and expenses incurred by the Trustee in connection with this
Section shall not be reimbursable from the Trust Fund.

                  The Master Servicer and the Company each agree to promptly
furnish to the Trustee, from time to time upon request, such further
information, reports and financial statements within their respective control
related to this Agreement and the Mortgage Loans as the Trustee reasonably deems
appropriate to prepare and file all necessary reports with the Commission.

                  SECTION 3.27.             Administration of Buydown Funds.

                  (a) With respect to any Buydown Mortgage Loan, the
Sub-Servicer has deposited Buydown Funds in an account that satisfies the
requirements for a Sub-Servicing Account (the "Buydown Account"). The Master
Servicer shall cause the Sub-Servicing Agreement to require that upon receipt
from the Mortgagor of the amount due on a Due Date for each Buydown Mortgage
Loan, the Sub-Servicer will withdraw from the Buydown Account the predetermined
amount that, when added to the amount due on such date from the Mortgagor,
equals the full Monthly Payment and transmit that amount in accordance with the
terms of the Sub-Servicing Agreement to the Master Servicer together with the
related payment made by the Mortgagor or advanced by the Sub-Servicer.

                  (b) If the Mortgagor on a Buydown Mortgage Loan prepays such
loan in its entirety during the period (the "Buydown Period") when Buydown Funds
are required to be applied to such Buydown Mortgage Loan, the Sub-Servicer shall
be required to withdraw from the Buydown


                                       70

<PAGE>



Account and remit any Buydown Funds remaining in the Buydown Account in
accordance with the related buydown agreement. The amount of Buydown Funds which
may be remitted in accordance with the related buydown agreement may reduce the
amount required to be paid by the Mortgagor to fully prepay the related Mortgage
Loan. If the Mortgagor on a Buydown Mortgage Loan defaults on such Mortgage Loan
during the Buydown Period and the property securing such Buydown Mortgage Loan
is sold in the liquidation thereof (either by the Master Servicer or the insurer
under any related Primary Insurance Policy), the Sub-Servicer shall be required
to withdraw from the Buydown Account the Buydown Funds for such Buydown Mortgage
Loan still held in the Buydown Account and remit the same to the Master Servicer
in accordance with the terms of the Sub-Servicing Agreement for deposit in the
Custodial Account or, if instructed by the Master Servicer, pay to the insurer
under any related Primary Insurance Policy if the Mortgaged Property is
transferred to such insurer and such insurer pays all of the loss incurred in
respect of such default. Any amount so remitted pursuant to the preceding
sentence will be deemed to reduce the amount owed on the Mortgage Loan.

                         PAYMENTS TO CERTIFICATEHOLDERS


                  SECTION 4.01.             Distributions.

                  (a) The Trustee shall establish and maintain a Certificate
Account, in which the Master Servicer shall cause to be deposited on behalf of
the Trustee on or before 5:00 P.M. New York time on each Certificate Account
Deposit Date by wire transfer of immediately available funds an amount equal to
the sum of (i) any Advance for the immediately succeeding Distribution Date,
(ii) any amount required to be deposited in the Certificate Account pursuant to
Sections 3.11, 3.13, 3.22 or 3.23, (iii) all other amounts constituting the
Available Distribution Amount for the immediately succeeding Distribution Date

aside and held in trust and credited to the account of the appropriate non-
tendering Holder or Holders. If any Certificates as to which notice has been
given pursuant to this Section 4.01(i) shall not have been surrendered for
cancellation within six months after the time specified in such notice, the
Trustee shall mail a second notice to the remaining non-tendering
Certificateholders to surrender their Certificates for cancellation in order to

the second notice all such Certificates shall not have been surrendered for
cancellation, the Trustee shall take reasonable steps as directed by the
Company, or appoint an agent to take reasonable steps, to contact the remaining
non-tendering Certificateholders concerning surrender of their Certificates. The
costs and expenses of maintaining the funds in trust and of contacting such
Certificateholders shall be paid out of the assets remaining in the Trust Fund.
If within nine months after the second notice any such Certificates shall not
have been surrendered for cancellation, the Class R Certificateholders shall be
entitled to all unclaimed funds and other assets which remain subject hereto. No
interest shall accrue or be payable to any Certificateholder on any amount held
in trust as a result of such Certificateholder's failure to surrender its
Certificate(s) for final payment thereof in accordance with this Section
4.01(i).

                                            Master Servicer.

                  (a) On the Business Day following each Determination Date, the
Master Servicer shall deliver to the Trustee a report, prepared as of the close
of business on the Determination Date (the "Remittance Report"), in the form of
an electromagnetic tape or disk. The Remittance Report and any written
information supplemental thereto shall include such information with respect to
the Mortgage Loans that is required by the Trustee for purposes of making the
calculations and preparing the statement described in Sections 4.01 and 4.02, as
set forth in written specifications or guidelines issued by the Trustee from
time to time. The Trustee shall have no obligation to recompute, recalculate or
verify any information provided to it by the Master Servicer.

                  (b) The Master Servicer shall determine the aggregate amount
of Advances required to be made for the related Distribution Date, which shall
be in an aggregate amount equal to the sum of (1) the aggregate amount of
Monthly Payments (with each interest portion thereof adjusted to the Mortgage
Rate less the Servicing Fee Rate and any applicable Radian PMI Policy Rate),
other than Balloon Payments, less the amount of any related Debt Service
Reductions or reductions in the amount of interest collectable from the
Mortgagor pursuant to the Relief Act, on the Outstanding Mortgage Loans as of
the related Due Date, which Monthly Payments were delinquent as of the close of
business as of the related Determination Date plus (2) with respect to each
Balloon Loan delinquent in respect of its Balloon Payment as of the close of
business on the related Determination Date, an amount equal to the assumed
Monthly Payment (net of the related Servicing Fees) that would have been due on
the related Due Date based on the original principal amortization scheduled for
such Balloon Loan until such Balloon Loan is finally liquidated; provided that
no Advance shall be made if it would be a Nonrecoverable Advance. On or before
4:00 P.M. New York time on each Certificate Account Deposit Date, the Master
Servicer shall either (i) deposit in the Certificate Account from its own funds,
or funds received therefor from the Sub-Servicers, an amount equal to the
Advances to be made by the Master Servicer in respect of the related


                                       79

Distribution Date, (ii) withdraw from amounts on deposit in the Custodial
Account and deposit in the Certificate Account all or a portion of the amounts
held for future distribution in discharge of any such Advance, or (iii) make
advances in the form of any combination of (i) and (ii) aggregating the amount
of such Advance. Any portion of the amounts held for future distribution so used
shall be replaced by the Master Servicer by deposit in the Certificate Account
on or before 1:00 P.M. New York time on any future Certificate Account Deposit
Date to the extent that funds attributable to the Mortgage Loans that are
available in the Custodial Account for deposit in the Certificate Account on
such Certificate Account Deposit Date shall be less than payments to
Certificateholders required to be made on the following Distribution Date. The
amount of any reimbursement pursuant to Section 3.11 in respect of outstanding
Advances on any Distribution Date shall be allocated to specific Monthly
Payments due but delinquent for previous Due Periods, which allocation shall be
made, to the extent practicable, to Monthly Payments which have been delinquent
for the longest period of time. Such allocations shall be conclusive for
purposes of reimbursement to the Master Servicer from recoveries on related
Mortgage Loans pursuant to Section 3.11. The determination by the Master
Servicer that it has made a Nonrecoverable Advance or that any proposed Advance,
if made, would constitute a Nonrecoverable Advance, shall be evidenced by a
certificate of a Servicing Officer delivered to the Seller and the Trustee with
the Remittance Report. The Trustee shall deposit all funds it receives pursuant
to this Section 4.03 into the Certificate Account.

                  (c) In the event that the Master Servicer determines as of any
Certificate Account Deposit Date that it will be unable to deposit in the
Certificate Account an amount equal to the Advance required to be made for the
immediately succeeding Distribution Date in the amount determined by the Master
Servicer pursuant to paragraph (b) above, it shall give notice to the Trustee of

Agreement in accordance with Section 7.01 and (b) assume the rights and
obligations of the Master Servicer hereunder, including the obligation to
deposit in the Certificate Account an amount equal to the Advance for the

                                    (B) to the Holders of REMIC 1 Regular
                  Interest LT1A, until the Uncertificated Principal Balance of
                  REMIC 1 Regular Interest LT1A is reduced to

Charges in respect of the Mortgage Loans received during the related Prepayment
Period and any Master Servicer Prepayment Charge Payment Amounts paid by the
Master Servicer during the related Prepayment Period will be distributed by
REMIC 1 to the Holders of REMIC 1 Regular Interest LT1P. The payment of the

reduce the Uncertificated Principal Balance thereof.

                  On each Distribution Date, the Trustee shall cause in the
following order of priority, the following amounts to be distributed by REMIC 2
to REMIC 3 on account of the REMIC 2 Regular Interests or withdrawn from the

         REMIC 2 Regular Interest A-IO, in an amount equal to (A) the

         respect thereof remaining unpaid from previous Distribution Dates.
         Amounts payable as Uncertificated Accrued Interest in respect of REMIC
         2 Regular Interest LT2I shall be reduced when the REMIC 2
         Overcollateralized Amount is less than the REMIC 2 Target
         Overcollateralized Amount, by the lesser of (x) the amount of such
         difference and (y) the Maximum LT2I Uncertificated Accrued Interest
         Deferral Amount;

                  (ii) second, to the Holders of REMIC 2 Regular Interests, in
         an amount equal to the remainder of the Available Funds for such
         Distribution Date after the distributions made pursuant to clause (i)
         above, allocated as follows:

                           (a) to the Holders of REMIC 2 Regular Interest LT2A,
                  98.00% of such remainder, until the Uncertificated Principal
                  Balance of such Uncertificated REMIC 2 Regular Interest is
                  reduced to zero;

                           (b) to the Holders of REMIC 2 Regular Interest LT2B,
                  REMIC 2 Regular Interest LT2C, REMIC 2 Regular Interest LT2D,
                  REMIC 2 Regular Interest LT2E, REMIC 2 Regular Interest LT2F,

                  LT2H, 1.00% of such remainder, in the same proportion as
                  principal payments are allocated to the Corresponding
                  Certificates, until the Uncertificated Principal Balances of
                  such REMIC 2 Regular Interests are reduced to zero;

                           (c) to the Holders of REMIC 2 Regular Interest LT2I,

                  on the Distribution Date immediately following the expiration
                  of the latest Prepayment Charge as identified on the

                  until $100 has been distributed pursuant to this clause; then

                           (e) any remaining amount to the Holders of the Class
                  R Certificates (in respect of the Class R-2 Interest); and

                  (iii) third, to REMIC 2 Regular Interest LT2P, 100% of the

         Prepayment Charge Payment Amounts on REMIC I Regular Interest LT1P;

provided, however, that 98.00% and 2.00% of any principal payments that are
attributable to an Overcollateralization Release Amount shall be allocated to
Holders of REMIC 2 Regular Interest LT2A and REMIC 2 Regular Interest LT2I,
respectively.

                  SECTION 4.05.             Allocation of Realized Losses.

                  (a) All Realized Losses on the Mortgage Loans shall be
allocated by the Trustee on each Distribution Date as follows: first, to Net
Monthly Excess Cashflow; second, to the Class C Certificates, until the
Certificate Principal Balance thereof has been reduced to zero; third, to the
Class B Certificates, until the Certificate Principal Balance thereof has been
reduced to zero; fourth, to the Class M-2 Certificates, until the Certificate
Principal Balance thereof has been reduced to zero; and fifth, to the Class M-1
Certificates, until the Certificate Principal Balance thereof has been reduced
to zero. All Realized Losses to be allocated to the Certificate Principal
Balances of all Classes on any Distribution Date shall be so allocated after the
actual distributions to be made on such date as provided above. All references
above to the Certificate Principal Balance of any Class of Certificates shall be
to the Certificate Principal Balance of such Class immediately prior to the
relevant Distribution Date, before reduction thereof by any Realized Losses, in
each case to be allocated to such Class of Certificates, on such Distribution
Date.

         Any allocation of Realized Losses to a Mezzanine Certificate on any
Distribution Date shall be made by reducing the Certificate Principal Balance
thereof by the amount so allocated. Any allocation of Realized Losses to a Class
C Certificate shall be made by reducing the amount otherwise payable in respect
thereof pursuant to Section 4.01(d)(viii). No allocations of any Realized Losses
shall be made to the Certificate Principal Balances of the Class A Certificates
or the Class P Certificates.

                  (b) All Realized Losses on the Mortgage Loans shall be
allocated by the Trustee on each Distribution Date to REMIC 1 Regular Interest
LT1A until the Uncertificated Principal Balance has been reduced to zero and
then to REMIC 1 Regular Interest LT1B until the Uncertificated Principal Balance
has been reduced to zero.

                  (c) All Realized Losses on the REMIC 1 Regular Interest LT1A
and REMIC 1 Regular Interest LT1B shall be deemed to have been allocated in the
specified percentages, as follows: first, to Uncertificated Accrued Interest
payable to the REMIC 2 Regular Interest LT2A and REMIC 2 Regular Interest LT2I
up to an aggregate amount equal to the REMIC 2 Interest Loss Allocation Amount,
98% and 2%, respectively; second, to the Uncertificated Principal Balances of
REMIC 2 Regular Interest LT2A and REMIC 2 Regular Interest LT2I up to an
aggregate amount equal to the REMIC 2 Principal Loss Allocation Amount, 98% and
2%, respectively; third, to the Uncertificated Principal Balances of REMIC 2
Regular Interest LT2A, REMIC 2 Regular Interest LT2H and REMIC 2 Regular
Interest LT2I, 98%, 1% and 1%, respectively, until the Uncertificated Principal
Balance of REMIC 2 Regular Interest LT2H has been reduced to zero; fourth, to
the Uncertificated Principal Balances of REMIC 2 Regular Interest LT2A, REMIC 2
Regular Interest LT2G and REMIC 2 Regular Interest LT2I, 98%, 1% and 1%,
respectively, until the Uncertificated Principal Balance of REMIC 2 Regular
Interest LT2G has been reduced to zero; and fifth, to the Uncertificated
Principal Balances of REMIC 2 Regular Interest LT2A, REMIC 2 Regular Interest
LT2F and REMIC 2 Regular Interest LT2I, 98%, 1% and 1%, respectively, until the
Uncertificated Principal Balance of REMIC 2 Regular Interest LT2F has been

                  SECTION 4.06.             Information Reports to Be Filed by
                                            the Master Servicer.

                  The Master Servicer or the Sub-Servicers shall file
information reports with respect to the receipt of mortgage interest received in
a trade or business, foreclosures and abandonments of any Mortgaged Property and
the information returns relating to cancellation of indebtedness income with
respect to any Mortgaged Property required by Sections 6050H, 6050J and 6050P of
the Code, respectively, and deliver to the Trustee an Officers' Certificate
stating that such reports have been filed. Such reports shall be in form and
substance sufficient to meet the reporting requirements imposed by such Sections
6050H, 6050J and 6050P of the Code.

                  SECTION 4.07.             Compliance with Withholding
                                            Requirements.

                  Notwithstanding any other provision of this Agreement, the
Trustee shall comply with all federal withholding requirements respecting
payments to Certificateholders of interest or original issue discount on the
Mortgage Loans, that the Trustee reasonably believes are applicable under the
Code. The consent of Certificateholders shall not be required for such
withholding. In the event the Trustee withholds any amount from interest or
original issue discount payments or advances thereof to any Certificateholder
pursuant to federal withholding requirements, the Trustee shall, together with
its monthly report to such Certificateholders pursuant to Section 4.02 hereof,
indicate such amount withheld.

                                THE CERTIFICATES


                  SECTION 5.01.             The Certificates.

                  (a) The Certificates will be substantially in the respective
forms annexed hereto as Exhibits A-1 through A-11. The Certificates will be
issuable in registered form only. The Certificates (other than the Class P
Certificates, the Class C Certificates and the Class R Certificates) will be
issued in minimum denominations of $25,000 Initial Certificate Principal Balance
or Initial Notional Amount, as applicable, and integral multiples of $1 in
excess thereof. The Class C Certificates will be issued in minimum denominations
of $10,000 Initial Certificate Principal Balance and integral multiples of $1 in
excess thereof. The Class P Certificates and the Class R Certificates will each
be issuable in minimum denominations of any Percentage Interest representing
20.00% and multiples of 0.01% in excess thereof.

                  Upon original issue, the Certificates shall, upon the written
request of the Company executed by an officer of the Company, be executed and
delivered by the Trustee, authenticated by the Trustee and delivered to or upon
the order of the Company upon receipt by the Trustee of the documents specified
in Section 2.01. The Certificates shall be executed by manual or facsimile
signature on behalf of the Trustee in its capacity as trustee hereunder by a
Responsible Officer. Certificates bearing the manual or facsimile signatures of
individuals who were at the time they signed the proper officers of the Trustee
shall bind the Trustee, notwithstanding that such individuals or any of them
have ceased to hold such offices prior to the authentication and delivery of
such Certificates or did not hold such offices at the date of such Certificates.
No Certificate shall be entitled to any benefit under this Agreement, or be
valid for any purpose, unless there appears on such Certificate a certificate of
authentication substantially in the form provided for herein executed by the
Trustee by manual signature, and such certificate upon any Certificate shall be
conclusive evidence, and the only evidence, that such Certificate has been duly
authenticated and delivered hereunder. All Certificates issued on the Closing
Date shall be dated the Closing Date and any Certificates delivered thereafter
shall be dated the date of their authentication.

                  (b) The Class A Certificates and the Mezzanine Certificates
shall initially be issued as one or more Certificates registered in the name of
the Depository or its nominee and, except as provided below, registration of
such Certificates may not be transferred by the Trustee except to another
Depository that agrees to hold such Certificates for the respective Certificate
Owners with Ownership Interests therein. The Certificate Owners shall hold their
respective Ownership Interests in and to each of such Book-Entry Certificates
through the book-entry facilities of the Depository and, except as provided
below, shall not be entitled to Definitive Certificates in respect of such
Ownership Interests. All transfers by Certificate Owners of their respective
Ownership Interests in the Book-Entry Certificates shall be made in accordance
with the procedures established by the Depository Participant or brokerage firm
representing such Certificate Owner. Each Depository Participant shall transfer
the Ownership Interests only in the Book-Entry


                                       85

<PAGE>



Certificates of Certificate Owners it represents or of brokerage firms for which
it acts as agent in accordance with the Depository's normal procedures. The
Trustee shall not be required to monitor, determine or inquire as to compliance
with the transfer restrictions with respect to the Book-Entry Certificates, and
the Trustee shall have no liability for transfers of Ownership Interests in the
Book Entry Certificates made through the book-entry facilities of the Depositary
or between or among Depositary Participants or Certificate Owners, made in
violation of the applicable restrictions.

                  The Trustee, the Master Servicer and the Company may for all
purposes (including the making of payments due on the respective Classes of
Book-Entry Certificates) deal with the Depository as the authorized
representative of the Certificate Owners with respect to the respective Classes
of Book-Entry Certificates for the purposes of exercising the rights of
Certificateholders hereunder. The rights of Certificate Owners with respect to
the respective Classes of Book-Entry Certificates shall be limited to those
established by law and agreements between such Certificate Owners and the
Depository Participants and brokerage firms representing such Certificate
Owners. Multiple requests and directions from, and votes of, the Depository as
Holder of any Class of Book- Entry Certificates with respect to any particular
matter shall not be deemed inconsistent if they are made with respect to
different Certificate Owners. The Trustee may establish a reasonable record date
in connection with solicitations of consents from or voting by
Certificateholders and shall give notice to the Depository of such record date.

                  If (i)(A) the Company advises the Trustee in writing that the
Depository is no longer willing or able to properly discharge its
responsibilities as Depository and (B) the Company is unable to locate a
qualified successor or (ii) the Company at its option advises the Trustee in
writing that it elects to terminate the book-entry system through the
Depository, the Trustee shall notify all Certificate Owners, through the
Depository, of the occurrence of any such event and of the availability of
Definitive Certificates to Certificate Owners requesting the same. Upon
surrender to the Trustee of the Book-Entry Certificates by the Depository,
accompanied by registration instructions from the Depository for registration of
transfer, the Trustee shall, at the expense of the Company, issue the Definitive
Certificates. Neither the Company, the Master Servicer nor the Trustee shall be
liable for any actions taken by the Depository or its nominee, including,
without limitation, any delay in delivery of such instructions and may
conclusively rely on, and shall be protected in relying on, such instructions.
Upon the issuance of Definitive Certificates the Trustee and the Master Servicer
shall recognize the Holders of the Definitive Certificates as Certificateholders
hereunder.

                  (c) Each Certificate is intended to be a "security" governed
by Article 8 of the Uniform Commercial Code as in effect in the State of New
York and any other applicable jurisdiction, to the extent that any of such laws
may be applicable.

                  SECTION 5.02.             Registration of Transfer and
                                            Exchange of Certificates.

                  (a) The Trustee shall maintain a Certificate Register in
which, subject to such reasonable regulations as it may prescribe, the Trustee
shall provide for the registration of Certificates and of transfers and
exchanges of Certificates as herein provided.

                  (b) Except as provided in Section 5.02(c), no transfer, sale,
pledge or other disposition of a Class P Certificate, Class C Certificate or a
Class R Certificate shall be made unless such transfer, sale, pledge or other
disposition is exempt from the registration requirements of the Securities Act
of 1933, as amended (the "Act"), and any applicable state securities laws or is
made in accordance with said Act and laws. In the event that a transfer of a
Class P Certificate, Class C Certificate or Class R Certificate is to be made
under this Section 5.02(b), (i) the Trustee shall require an Opinion of Counsel
acceptable to and in form and substance satisfactory to the Trustee that such
transfer shall be made pursuant to an exemption, describing the applicable
exemption and the basis therefor, from said Act and laws or is being made
pursuant to said Act and laws, which Opinion of Counsel shall not be an expense
of the Trustee, the Company or the Master Servicer, provided that such Opinion
of Counsel will not be required in connection with the initial transfer of any
such Certificate by the Company or any affiliate thereof, to a non-affiliate of
the Company and (ii) the Trustee shall require the transferee to execute a
representation letter, substantially in the form of Exhibit G-1 hereto, and the
Trustee shall require the transferor to execute a representation letter,
substantially in the form of Exhibit G-2 hereto, each acceptable to and in form
and substance satisfactory to the Trustee certifying to the Company and the
Trustee the facts surrounding such transfer, which representation letters shall
not be an expense of the Trustee, the Company or the Master Servicer; provided
however that such representation letters will not be required in connection with
any transfer of any such Certificate by the Company to an affiliate of the
Company and the Trustee shall be entitled to conclusively rely upon a
representation (which, upon the request of the Trustee, shall be a written
representation) from the Company of the status of such transferee as an
affiliate of the Company. Any such Certificateholder desiring to effect such
transfer shall, and does hereby agree to, indemnify the Trustee, the Company and
the Master Servicer against any liability that may result if the transfer is not
so exempt or is not made in accordance with such applicable federal and state
laws.

                  (c) Notwithstanding the requirements of Section 5.02(b),
transfers of Class P Certificates, Class C Certificates and Class R Certificates
may be made in accordance with this Section 5.02(c) if the prospective
transferee of a Certificate provides the Trustee and the Company with an
investment letter substantially in the form of Exhibit G-3 attached hereto,
which investment letter shall not be an expense of the Trustee, the Company or
the Master Servicer, and which investment letter states that, among other
things, such transferee is a "qualified institutional buyer" as defined under
Rule 144A. Such transfers shall be deemed to have complied with the requirements
of Section 5.02(b) hereof; provided, however, that no Transfer of any of the
Class P Certificates, Class C Certificates or Class R Certificates may be made
pursuant to this Section 5.02(c) by the Company. Any such Certificateholder
desiring to effect such transfer shall, and does hereby agree to, indemnify the
Trustee, the Company and the Master Servicer against any liability that may
result


                                       87

<PAGE>



if the transfer is not so exempt or is not made in accordance with such
applicable federal and state laws.

                  The Trustee shall require an Opinion of Counsel from a
prospective transferee prior to the transfer of any Class P Certificate, Class C
Certificate or Class R Certificate to any employee benefit plan or other
retirement arrangement, including individual retirement accounts and Keogh
plans, that is subject to Section 406 of the Employee Retirement Income Security
Act of 1974, as amended ("ERISA") or Section 4975 of the Code (any of the
foregoing, a "Plan"), to a trustee or other Person acting on behalf of any Plan,
or to any other person who is using "plan assets" of any Plan to effect such
acquisition (including any insurance company using funds in its general or
separate accounts that may constitute "plan assets"). Such Opinion of Counsel
must establish to the satisfaction of the Trustee that such transfer is
permissible under applicable law, will not violate the prohibited transaction
provisions of Section 406 of ERISA and Section 4975 of the Code, will not cause
the assets of the Trust Fund to constitute "plan assets" within the meaning of
29 C.F.R. ss.2510.3-101, and will not subject the Trustee, the Master Servicer
or the Company to any obligation in addition to those undertaken in this
Agreement. Neither the Company, the Master Servicer nor the Trustee will be
required to obtain such Opinion of Counsel on behalf of any prospective
transferee.

                  (e) (i) Each Person who has or who acquires any Ownership
Interest in a Class R Certificate shall be deemed by the acceptance or
acquisition of such Ownership Interest to have agreed to be bound by the
following provisions and to have irrevocably authorized the Trustee or its
designee under clause (iii)(A) below to deliver payments to a Person other than
such Person and to negotiate the terms of any mandatory sale under clause
(iii)(B) below and to execute all instruments of transfer and to do all other
things necessary in connection with any such sale. The rights of each Person
acquiring any Ownership Interest in a Class R Certificate are expressly subject
to the following provisions:

                  (A) Each Person holding or acquiring any Ownership Interest in
         a Class R Certificate shall be a Permitted Transferee and shall
         promptly notify the Trustee of any change or impending change in its
         status as a Permitted Transferee.

                  (B) In connection with any proposed Transfer of any Ownership
         Interest in a Class R Certificate, the Trustee shall require delivery
         to it, and shall not register the Transfer of any Class R Certificate
         until its receipt of (I) an affidavit and agreement (a "Transfer
         Affidavit and Agreement" in the form attached hereto as Exhibit G-5)
         from the proposed Transferee, in form and substance satisfactory to the
         Trustee representing and warranting, among other things, that it is a
         Permitted Transferee, that it is not acquiring its Ownership Interest
         in the Class R Certificate that is the subject of the proposed Transfer
         as a nominee, trustee or agent for any Person who is not a Permitted
         Transferee, that for so long as it retains its Ownership Interest in a
         Class R Certificate, it will endeavor to remain a Permitted Transferee,
         and that it has reviewed the provisions of this Section 5.02 and agrees
         to be bound by them, and (II) a certificate, in the form attached
         hereto as Exhibit G-4, from the Holder wishing to transfer the Class R
         Certificate, in form and substance satisfactory to the Trustee
         representing and


                                       88

<PAGE>



         warranting, among other things, that no purpose of the proposed
         Transfer is to impede the assessment or collection of tax.

                  (C) Notwithstanding the delivery of a Transfer Affidavit and
         Agreement by a proposed Transferee under clause (B) above, if a
         Responsible Officer of the Trustee assigned to this transaction has
         actual knowledge that the proposed Transferee is not a Permitted
         Transferee, no Transfer of an Ownership Interest in a Class R
         Certificate to such proposed Transferee shall be effected.

                  (D) Each Person holding or acquiring any Ownership Interest in
         a Class R Certificate shall agree (x) to require a Transfer Affidavit
         and Agreement from any other Person to whom such Person attempts to
         transfer its Ownership Interest in a Class R Certificate and (y) not to
         transfer its Ownership Interest unless it provides a certificate to the
         Trustee in the form attached hereto as Exhibit G-4.

                  (E) Each Person holding or acquiring an Ownership Interest in
         a Class R Certificate, by purchasing an Ownership Interest in such
         Certificate, agrees to give the Trustee written notice that it is a
         "pass-through interest holder" within the meaning of Temporary Treasury
         Regulations Section 1.67-3T(a)(2)(i)(A) immediately upon acquiring an
         Ownership Interest in a Class R Certificate, if it is "a pass-through
         interest holder", or is holding an Ownership Interest in a Class R
         Certificate on behalf of a "pass-through interest holder."

                  (ii) The Trustee will register the Transfer of any Class R
Certificate only if it shall have received the Transfer Affidavit and Agreement
in the form attached hereto as Exhibit G-5, a certificate of the Holder
requesting such transfer in the form attached hereto as Exhibit G-4 and all of
such other documents as shall have been reasonably required by the Trustee as a
condition to such registration. Transfers of the Class R Certificates other than
to Permitted Transferees are prohibited.

                  (iii) (A) If any Person other than a Permitted Transferee
shall become a Holder of a Class R Certificate, then the last preceding
Permitted Transferee shall be restored, to the extent permitted by law, to all
rights and obligations as Holder thereof retroactive to the date of registration
of such Transfer of such Class R Certificate. If a Non-United States Person
shall become a Holder of a Class R Certificate, then the last preceding
Permitted Transferee shall be restored, to the extent permitted by law, to all
rights and obligations as Holder thereof retroactive to the date of registration
of such Transfer of such Class R Certificate. If a transfer of a Class R
Certificate is disregarded pursuant to the provisions of Treasury Regulations
Section 1.860E-1 or Section 1.860G-3, then the last preceding Permitted
Transferee shall be restored, to the extent permitted by law, to all rights and
obligations as Holder thereof retroactive to the date of registration of such
transfer of such Class R Certificate. The prior Holder shall be entitled to
recover from any purported Holder of a Class R Certificate that was in fact not
a Permitted Transferee under this Section 5.05(b) at the time it became a Holder
all payments made on such Class R Certificate. Each Holder of a Class R
Certificate, by acceptance thereof, shall be deemed for all purposes to have
consented to the provisions of this clause (b) and to any amendment of this
Agreement deemed necessary (whether


                                       89

<PAGE>



as a result of new legislation or otherwise) by counsel of the Company to ensure
that the Class R Certificates are not transferred to any Person who is not a
Permitted Transferee and that any transfer of such Class R Certificates will not
cause the imposition of a tax upon the Trust or cause any such REMIC to fail to
qualify as a REMIC. The Trustee shall be under no liability to any Person for
any registration of Transfer of a Class R Certificate that is in fact not
permitted by this Section 5.02 or for making any payments due on such
Certificate to the holder thereof or for taking any other action with respect to
such holder under the provisions of this Agreement.

                           (B) If any purported Transferee shall become a Holder
of a Class R Certificate in violation of the restrictions in this Section 5.02
and to the extent that the retroactive restoration of the rights of the Holder
of such Class R Certificate as described in clause (iii)(A) above shall be
invalid, illegal or unenforceable, then the Trustee shall have the right,
without notice to the holder or any prior holder of such Class R Certificate, to
sell such Class R Certificate to a purchaser selected by the Trustee on such
terms as the Trustee may choose. Such purported Transferee shall promptly
endorse and deliver each Class R Certificate in accordance with the instructions
of the Trustee. Such purchaser may be the Trustee itself. The proceeds of such
sale, net of the commissions (which may include commissions payable to the
Trustee), expenses and taxes due, if any, will be remitted by the Trustee to
such purported Transferee. The terms and conditions of any sale under this
clause (iii)(B) shall be determined in the sole discretion of the Trustee, and
the Trustee shall not be liable to any Person having an Ownership Interest in a
Class R Certificate as a result of its exercise of such discretion.

                  (iv) The Trustee shall make available to the Internal Revenue
Service and those Persons specified by the REMIC Provisions, all information
necessary to compute any tax imposed (A) as a result of the transfer of an
ownership interest in a Class R Certificate to any Person who is a Disqualified
Organization, including the information regarding "excess inclusions" of such
Class R Certificates required to be provided to the Internal Revenue Service and
certain Persons as described in Treasury Regulations Sections 1.860D-1(b)(5) and
1.860E-2(a)(5), and (B) as a result of any regulated investment company, real
estate investment trust, common trust fund, partnership, trust, estate or
organization described in Section 1381 of the Code that holds an Ownership
Interest in a Class R Certificate having as among its record holders at any time
any Person who is a Disqualified Organization. The Trustee may charge and shall
be entitled to reasonable compensation for providing such information as may be
required from those Persons which may have had a tax imposed upon them as
specified in clauses (A) and (B) of this paragraph for providing such
information.

                  (f) Subject to the preceding paragraphs, upon surrender for
registration of transfer of any Certificate at the office of the Trustee
maintained for such purpose, the Trustee shall execute and the Trustee shall
authenticate and deliver, in the name of the designated transferee or
transferees, one or more new Certificates of the same Class of a like aggregate
Percentage Interest. Every Certificate surrendered for transfer shall be
accompanied by notification of the account of the designated transferee or
transferees for the purpose of receiving distributions pursuant to Section 4.01
by wire transfer, if any such transferee desires and is eligible for
distribution by wire transfer.



                                       90

<PAGE>



                  (g) At the option of the Certificateholders, Certificates may
be exchanged for other Certificates of authorized denominations of the same
Class of a like aggregate Percentage Interest, upon surrender of the
Certificates to be exchanged at the office of the Trustee. Whenever any
Certificates are so surrendered for exchange the Trustee shall execute,
authenticate and deliver the Certificates which the Certificateholder making the
exchange is entitled to receive. Every Certificate presented or surrendered for
transfer or exchange shall (if so required by the Trustee) be duly endorsed by,
or be accompanied by a written instrument of transfer in the form satisfactory
to the Trustee duly executed by, the Holder thereof or his attorney duly
authorized in writing.

                  (h) No service charge shall be made to the Certificateholders
for any transfer or exchange of Certificates, but the Trustee may require
payment of a sum sufficient to cover any tax or governmental charge that may be
imposed in connection with any transfer or exchange of Certificates.

                  (i) All Certificates surrendered for transfer and exchange
shall be canceled and retained by the Trustee in accordance with the Trustee's
standard procedures.

                  SECTION 5.03.             Mutilated, Destroyed, Lost or Stolen
                                            Certificates.

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

                  SECTION 5.04.             Persons Deemed Owners.

                  The Company, the Master Servicer, the Trustee and any agent of
any of them may treat the person in whose name any Certificate is registered as
the owner of such Certificate for the purpose of receiving distributions
pursuant to Section 4.01 and for all other purposes whatsoever, and neither the
Company, the Master Servicer, the Trustee nor any agent of any of them shall be
affected by notice to the contrary.

                  SECTION 5.05.             Rule 144A Information.

                  For so long as any Class P Certificates, Class C Certificates
and Class R Certificates are outstanding and are "restricted securities" within
the meaning of Rule 144(a)(3) of the Securities


                                       91

<PAGE>



Act, (1) the Company will provide or cause to be provided to any holder of such
Certificates and any prospective purchaser thereof designated by such a holder,
upon the request of such holder or prospective purchaser, the information
required to be provided to such holder or prospective purchaser by Rule
144A(d)(4) under the Securities Act; and (2) the Company shall update such
information from time to time in order to prevent such information from becoming
false and misleading and will take such other actions as are necessary to ensure
that the safe harbor exemption from the registration requirements of the
Securities Act under Rule 144A is and will be available for resales of such
Certificates conducted in accordance with Rule 144A. The Master Servicer shall
cooperate with the Company and furnish the Company such information in the
Master Servicer's possession as the Company may reasonably request.

                                   ARTICLE VI

                       THE COMPANY AND THE MASTER SERVICER

                  SECTION 6.01.             Liability of the Company and the
                                            Master Servicer.

                  The Company and the Master Servicer each shall be liable in
accordance herewith only to the extent of the obligations specifically imposed
upon and undertaken by the Company and the Master Servicer herein. Only the
Master Servicer, any successor Master Servicer or the Trustee acting as Master
Servicer shall be liable with respect to the servicing of the Mortgage Loans and
the REO Property for actions taken by any such Person in contravention of the
Master Servicer's duties hereunder.

                  SECTION 6.02.             Merger, Consolidation or Conversion
                                            of the Company or the Master
                                            Servicer.

                  The Company and the Master Servicer each will keep in full
effect its existence, rights and franchises as a corporation under the laws of
the state of its incorporation, and each will obtain and preserve its
qualification to do business as a foreign corporation in each jurisdiction in
which such qualification is or shall be necessary to protect the validity and
enforceability of this Agreement, the Certificates or any of the Mortgage Loans
and to perform its respective duties under this Agreement.

                  Any Person into which the Company or the Master Servicer may
be merged, consolidated or converted, or any corporation resulting from any
merger or consolidation to which the Company or the Master Servicer shall be a
party, or any Person succeeding to the business of the Company or the Master
Servicer, shall be the successor of the Company or the Master Servicer, as the
case may be, hereunder, without the execution or filing of any paper or any
further act on the part of any of the parties hereto, anything herein to the
contrary notwithstanding; provided, however, that the successor or surviving
Person to the Master Servicer shall be qualified to sell mortgage loans to and
service mortgage loans for Fannie Mae or Freddie Mac.

                  SECTION 6.03.             Limitation on Liability of the
                                            Company, the Master Servicer and
                                            Others.

                  Neither the Company, the Master Servicer nor any of the
directors, officers, employees or agents of the Company or the Master Servicer
shall be under any liability to the Trust Fund or the Certificateholders for any
action taken or for refraining from the taking of any action in good faith
pursuant to this Agreement, or for errors in judgment; provided, however, that
this provision shall not protect the Company or the Master Servicer (but this
provision shall protect the above described persons) against any breach of
warranties or representations made herein, or against any specific liability
imposed on the Master Servicer pursuant to Section 3.01 or any other Section
hereof; and provided further that this provision shall not protect the Company,
the Master Servicer or any such person, against any liability which would
otherwise be imposed by reason of willful


                                       93

<PAGE>



misfeasance, bad faith or gross negligence in the performance of duties or by
reason of reckless disregard of obligations and duties hereunder. The Company,
the Master Servicer and any director, officer, employee or agent of the Company
or the Master Servicer may rely in good faith on any document of any kind PRIMA
FACIE properly executed and submitted by any Person respecting any matters
arising hereunder. The Company, the Master Servicer and any director, officer,
employee or agent of the Company or the Master Servicer shall be indemnified and
held harmless by the Trust Fund against any loss, liability or expense incurred
in connection with any legal action relating to this Agreement or the
Certificates (including reasonable legal fees and disbursements of counsel),
other than (a) any loss, liability or expense related to Master Servicer's
servicing obligations with respect to any specific Mortgage Loan or Mortgage
Loans (except as any such loss, liability or expense shall be otherwise
reimbursable pursuant to this Agreement) or related to the Master Servicer's
obligations under Section 3.01, or (b) any loss, liability or expense incurred
by reason of willful misfeasance, bad faith or gross negligence in the
performance of duties hereunder or by reason of reckless disregard of
obligations and duties hereunder. Neither the Company nor the Master Servicer
shall be under any obligation to appear in, prosecute or defend any legal action
which is not incidental to its respective duties under this Agreement and which
in its opinion may involve it in any expense or liability; provided, however,
that the Company or the Master Servicer may in its sole discretion undertake any
such action which it may deem necessary or desirable with respect to this
Agreement and the rights and duties of the parties hereto and the interests of
the Certificateholders hereunder. In such event, the legal expenses and costs of
such action and any liability resulting therefrom (except any action or
liability related to the Master Servicer's obligations under Section 3.01) shall
be expenses, costs and liabilities of the Trust Fund, and the Company and the
Master Servicer shall be entitled to be reimbursed therefor from the Certificate
Account as provided in Section 3.11, any such right of reimbursement being prior
to the rights of Certificateholders to receive any amount in the Certificate
Account.

                  SECTION 6.04.             Limitation on Resignation of the
                                            Master Servicer.

                  The Master Servicer shall not resign from the obligations and
duties hereby imposed on it except (a) upon appointment of a successor servicer
reasonably acceptable to the Trustee upon receipt by the Trustee of a letter
from each Rating Agency (obtained by the Master Servicer and at its expense)
that such a resignation and appointment will not, in and of itself, result in a
downgrading of the Certificates or (b) upon determination that its duties
hereunder are no longer permissible under applicable law. Any such determination
permitting the resignation of the Master Servicer shall be evidenced by an
Opinion of Counsel (at the expense of the resigning Master Servicer) to such
effect delivered to the Trustee. No such resignation shall become effective
until the Trustee or a successor servicer shall have assumed the Master
Servicer's responsibilities, duties, liabilities and obligations hereunder.

                  SECTION 6.05.             Sale and Assignment of Master
                                            Servicing.

                  The Master Servicer may sell and assign its rights and
delegate its duties and obligations in their entirety as Master Servicer under
this Agreement; provided, however, that: (i) the purchaser or transferee
accepting such assignment and delegation (a) shall be a Person which


                                       94

<PAGE>



shall be qualified to service mortgage loans for Fannie Mae or Freddie Mac; (b)
shall, in the case of successor master servicers only, have a net worth of not
less than $10,000,000 (unless otherwise approved by each Rating Agency pursuant
to clause (ii) below); (c) shall be reasonably satisfactory to the Trustee (as
evidenced in a writing signed by the Trustee) as having a comparable servicing
ability to that of the Master Servicer on the Closing Date; (d) shall execute
and deliver to the Trustee an agreement, in form and substance reasonably
satisfactory to the Trustee, which contains an assumption by such Person of the
due and punctual performance and observance of each covenant and condition to be
performed or observed by it as master servicer under this Agreement and any
custodial agreement, from and after the effective date of such agreement; (ii)
each Rating Agency shall be given prior written notice of the identity of the
proposed successor to the Master Servicer and each Rating Agency's rating of the
Certificates in effect immediately prior to such assignment, sale and delegation
will not be downgraded or withdrawn as a result of such assignment, sale and
delegation, as evidenced by a letter to such effect obtained by the Master
Servicer at its expense and delivered to the Trustee; and (iii) the Master
Servicer assigning and selling the master servicing shall deliver to the Trustee
an Officer's Certificate and an Opinion of Counsel (at the expense of the Master
Servicer), each stating that all conditions precedent to such action under this
Agreement have been completed and such action is permitted by and complies with
the terms of this Agreement. No such assignment or delegation shall affect any
liability of the Master Servicer arising prior to the effective date thereof.

                                     DEFAULT

                  SECTION 7.01.             Events of Default.

                  "Event of Default", wherever used herein, means any one of the
following events:

                (i) any failure by the Master Servicer to deposit into the
         Certificate Account on each Certificate Account Deposit Date the
         amounts required to be deposited therein (other than an Advance) under
         the terms of this Agreement which continues unremedied for two (2)
         Business Days after such amount was required to be remitted; or

               (ii) any failure on the part of the Master Servicer duly to
         observe or perform in any material respect any other of the covenants
         or agreements on the part of the Master Servicer contained in the
         Certificates or in this Agreement (including any breach of the Master
         Servicer's representations and warranties pursuant to Section 2.03(a)
         which materially and adversely affects the interests of the
         Certificateholders) which continues unremedied for a period of 60 days
         after the date on which written notice of such failure, requiring the
         same to be remedied, shall have been given to the Master Servicer by
         the Trustee, or to the Master Servicer and the Trustee by the Holders
         of Certificates entitled to at least 25% of the Voting Rights; or

              (iii) a decree or order of a court or agency or supervisory
         authority having jurisdiction in an involuntary case under any present
         or future federal or state bankruptcy, insolvency or similar law or the
         appointment of a conservator or receiver or liquidator in any
         insolvency, readjustment of debt, marshaling of assets and liabilities
         or similar proceedings, or for the winding-up or liquidation of its
         affairs, shall have been entered against the Master Servicer and such
         decree or order shall have remained in force undischarged or unstayed
         for a period of 60 consecutive days; or

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

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

               (vi) the Master Servicer shall fail to deposit in the Certificate
         Account on any Certificate Account Deposit Date an amount equal to any
         required Advance which continues


                                       96

<PAGE>



         unremedied for the earlier of (a) a period of two (2) Business Days or
         (b) the Business Day immediately preceding the Distribution Date.

If an Event of Default described in clauses (i) - (v) of this Section shall
occur, then, and in each and every such case, so long as such Event of Default
shall not have been remedied, the Trustee or the Holders of Certificates
entitled to at least 51% of the Voting Rights, by notice in writing to the
Master Servicer (and to the Trustee if given by such Holders of Certificates),
with a copy to the Rating Agencies, may terminate all of the rights and
obligations (but not the liabilities) of the Master Servicer under this
Agreement and in and to the Trust Fund, other than its rights as a
Certificateholder hereunder; provided, however, that the successor to the Master
Servicer appointed pursuant to Section 7.02 shall have accepted the duties of
Master Servicer effective upon the resignation or termination of the Master
Servicer. If an Event of Default described in clause (vi) hereof shall occur,
the Trustee shall, by notice to the Master Servicer, and the Company, terminate
all of the rights and obligations of the Master Servicer under this Agreement
and in and to the Trust Fund, other than its rights as a Certificateholder
hereunder; provided, however, that if the Trustee determines (in its sole
discretion) that the failure by the Master Servicer to make any required Advance
was due to circumstances beyond its control, and the required Advance was
otherwise made, the Trustee shall not terminate the Master Servicer. On or after
the receipt by the Master Servicer of such notice, all authority and power of
the Master Servicer under this Agreement, whether with respect to the
Certificates (other than as a holder thereof) or the Mortgage Loans or
otherwise, shall pass to and be vested in the Trustee pursuant to and under this
Section, and, without limitation, the Trustee is hereby authorized and empowered
to execute and deliver, on behalf of the Master Servicer, as attorney-in-fact or
otherwise, any and all documents and other instruments, and to do or accomplish
all other acts or things necessary or appropriate to effect the purposes of such
notice of termination, whether to complete the transfer and endorsement or
assignment of the Mortgage Loans and related documents, or otherwise at the
expense of the Master Servicer. The Master Servicer agrees to cooperate with
(and pay any related costs and expenses of) the Trustee in effecting the
termination of the Master Servicer's responsibilities and rights hereunder,
including, without limitation, the transfer to the Trustee or the successor
Master Servicer for administration by it of (i) the property and amounts which
are then or should be part of the Trust Fund or which thereafter become part of
the Trust Fund; (ii) originals or copies of all documents of the Master Servicer
reasonably requested by the Trustee to enable it to assume the Master Servicer's
duties thereunder; (iii) the rights and obligations of the Master Servicer under
the Sub-Servicing Agreements with respect to the Mortgage Loans; and (iv) all
cash amounts which shall at the time be deposited by the Master Servicer or
should have been deposited to the Custodial or the Certificate Account or
thereafter be received with respect to the Mortgage Loans. The Trustee shall not
be deemed to have breached any obligation hereunder as a result of a failure to
make or delay in making any distribution as and when required hereunder caused
by the failure of the Master Servicer to remit any amounts received by it or to
deliver any documents held by it with respect to the Mortgage Loans. For
purposes of this Section 7.01, the Trustee shall not be deemed to have knowledge
of an Event of Default unless a Responsible Officer of the Trustee has actual
knowledge thereof or unless notice of any event which is in fact such an Event
of Default is received by the Trustee as provided in Section 11.05 and such
notice references the Certificates, the Trust Fund or this Agreement.

                  SECTION 7.02.             Trustee to Act; Appointment of
                                            Successor.

                  Within 90 days of the time the Master Servicer receives a
notice of termination pursuant to Section 7.01(i) - (v), the Trustee or its
appointed agent shall be the successor in all respects to the Master Servicer in
its capacity as Master Servicer under this Agreement and the transactions set
forth or provided for herein and shall be subject thereafter to all the
responsibilities, duties and liabilities relating thereto placed on the Master
Servicer including the obligation to make Advances which have been or will be
required to be made (except for the responsibilities, duties and liabilities
contained in Section 2.03 and its obligations to deposit amounts in respect of
losses pursuant to Section 3.12 and 4.01(h)) by the terms and provisions hereof;
and provided further, that any failure to perform such duties or
responsibilities caused by the Master Servicer's failure to provide information
required by Section 4.03 shall not be considered a default by the Trustee
hereunder. As compensation therefor, the Trustee shall be entitled to all funds
relating to the Mortgage Loans which the Master Servicer would have been
entitled to charge to the Custodial Account and the Certificate Account if the
Master Servicer had continued to act hereunder. If the Trustee has become the
successor to the Master Servicer in accordance with Section 6.04 or Section
7.02, then notwithstanding the above, if the Trustee shall be unwilling to so
act, or shall be unable to so act, the Trustee may appoint, or petition a court
of competent jurisdiction or appoint, any established housing and home finance
institution, which is also a Fannie Mae- or Freddie Mac- approved mortgage
servicing institution, having a net worth of not less than $10,000,000 as the
successor to the Master Servicer hereunder in the assumption of all or any part
of the responsibilities, duties or liabilities of the Master Servicer hereunder.
Pending appointment of a successor to the Master Servicer hereunder, the Trustee
shall act in such capacity as herein above provided. In connection with such
appointment and assumption, the Trustee may make such arrangements for the
compensation of such successor out of payments on Mortgage Loans as it and such
successor shall agree; provided, however, that no such compensation shall be in
excess of that permitted the Master Servicer hereunder. Each of the Seller, the
Trustee and such successor shall take such action, consistent with this
Agreement, as shall be necessary to effectuate any such succession. In no event
shall the sucessor Master Servicer be liable for the acts or omissions of the
predecessor Master Servicer.

                  Any successor, including the Trustee, to the Master Servicer
shall maintain in force during its term as master servicer hereunder policies
and fidelity bonds to the same extent as the Master Servicer is so required
pursuant to Section 3.18.

                  Notwithstanding anything else herein to the contrary, in no
event shall the Trustee be liable for any Servicing Fee or for any differential
in the amount of the Servicing Fee paid hereunder and the amount necessary to
induce any successor Master Servicer or Servicer, as applicable, to act as
successor Master Servicer or Servicer, as applicable, under this Agreement and
the transactions set forth or provided for herein.

                  SECTION 7.03.             Notification to Certificateholders.

                  (a) Upon any such termination or appointment of a successor to
the Master Servicer, the Trustee shall give prompt notice thereof to
Certificateholders and to the Rating Agencies.

                  (b) Within 60 days after the occurrence of any Event of
Default, the Trustee shall transmit by mail to all Holders of Certificates
notice of each such Event of Default hereunder known to the Trustee, unless such
Event of Default shall have been cured or waived.

                  SECTION 7.04.             Waiver of Events of Default.

                  The Holders representing at least 51% of the Voting Rights of
Certificates affected by a default or Event of Default hereunder, may waive such
default or Event of Default (other than an Event of Default set forth in Section
7.01(vi)); PROVIDED, HOWEVER, that (a) a default or Event of Default under
clause (i) of Section 7.01 may be waived only by all of the Holders of
Certificates affected by such default or Event of Default and (b) no waiver
pursuant to this Section 7.04 shall affect the Holders of Certificates in the
manner set forth in the second paragraph of Section 11.01 or materially
adversely affect any non-consenting Certificateholder. Upon any such waiver of a
default or Event of Default by the Holders representing the requisite percentage
of Voting Rights of Certificates affected by such default or Event of Default,
such default or Event of Default shall cease to exist and shall be deemed to
have been remedied for every purpose hereunder. No such waiver shall extend to
any subsequent or other default or Event of Default or impair any right
consequent thereon except to the extent expressly so waived. The Master Servicer
shall give notice of any such waiver to the Rating Agencies.

                  SECTION 7.05.             List of Certificateholders.

                  Upon written request of three or more Certificateholders of
record, for purposes of communicating with other Certificateholders with respect
to their rights under this Agreement, the Trustee will afford such
Certificateholders access during business hours to the most recent list of
Certificateholders held by the Trustee.

                                  ARTICLE VIII

                             CONCERNING THE TRUSTEE

                  SECTION 8.01.             Duties of Trustee.

                  The Trustee, prior to the occurrence of an Event of Default
and after the curing or waiver of all Events of Default which may have occurred,
undertakes to perform such duties and only such duties as are specifically set
forth in this Agreement. If an Event of Default occurs, is continuing and has
not been waived, the Trustee shall exercise such of the rights and powers vested
in it by this Agreement, and use the same degree of care and skill in their
exercise as a prudent man would exercise or use under the circumstances in the
conduct of his own affairs. Any permissive right of the Trustee enumerated in
this Agreement shall not be construed as a duty.

                  The Trustee, upon receipt of all resolutions, certificates,
statements, opinions, reports, documents, orders or other instruments furnished
to the Trustee which are specifically required to be furnished pursuant to any
provision of this Agreement, shall examine them in accordance with the
requirements of this Agreement. If any such instrument is found not to conform
to the requirements of this Agreement in a material manner, the Trustee shall
take such action as it deems appropriate to have the instrument corrected, and
if the instrument is not corrected to the Trustee's satisfaction, the Trustee
will provide notice thereof to the Certificateholders. Notwithstanding the
foregoing, the Trustee shall not be responsible for the accuracy or content of
any resolution, certificate, statement, opinion, report, document, order or
other instrument furnished by the Master Servicer hereunder or any Opinion of
Counsel required hereunder.

                  The Trustee shall prepare and file or cause to be filed on
behalf of the Trust Fund any tax return that is required with respect to REMIC
1, REMIC 2 and REMIC 3 pursuant to applicable federal, state or local tax laws.

                  The Trustee covenants and agrees that it shall perform its
obligations hereunder in a manner so as to maintain the status of REMIC 1, REMIC
2 and REMIC 3 under the REMIC Provisions and to prevent the imposition of any
federal, state or local income, prohibited transaction, contribution or other
tax on either REMIC 1, REMIC 2 or REMIC 3 to the extent that maintaining such
status and avoiding such taxes are within the control of the Trustee and are
reasonably within the scope of its duties under this Agreement.

                  No provision of this Agreement shall be construed to relieve
the Trustee from liability for its own negligent action, its own negligent
failure to act or its own willful misconduct; provided, however, that:

                         (i) Prior to the occurrence of an Event of Default, and
                  after the curing or waiver of all such Events of Default which
                  may have occurred, the duties and obligations of the Trustee
                  shall be determined solely by the express provisions of this
                  Agreement, the Trustee shall not be liable except for the
                  performance of such duties

<PAGE>



                  and obligations as are specifically set forth in this
                  Agreement, no implied covenants or obligations shall be read
                  into this Agreement against the Trustee and, in the absence of
                  bad faith on the part of the Trustee, the Trustee may
                  conclusively rely, as to the truth of the statements and the
                  correctness of the opinions expressed therein, upon any
                  certificates or opinions furnished to the Trustee and
                  conforming to the requirements of this Agreement;

                        (ii) The Trustee shall not be liable for an error of
                  judgment made in good faith by a Responsible Officer or
                  Responsible Officers of the Trustee, unless it shall be proved
                  that the Trustee was negligent in ascertaining the pertinent
                  facts; and

                       (iii) The Trustee shall not be liable with respect to any
                  action taken, suffered or omitted to be taken by it in good
                  faith in accordance with the direction of the Holders of
                  Certificates entitled to at least 25% of the Voting Rights
                  relating to the time, method and place of conducting any
                  proceeding for any remedy available to the Trustee, or
                  exercising any trust or power conferred upon the Trustee,
                  under this Agreement.

                  SECTION 8.02.             Certain Matters Affecting the
                                            Trustee.

                           Except as otherwise provided in Section 8.01:

                (a) The Trustee may conclusively rely upon and shall be fully
         protected in acting or refraining from acting in reliance upon any
         resolution, Officers' Certificate, certificate of auditors or any other
         certificate, statement, instrument, opinion, report, notice, request,
         consent, order, appraisal, bond or other paper or document reasonably
         believed by it to be genuine and to have been signed or presented by
         the proper party or parties;

                (b) The Trustee may consult with counsel and any Opinion of
         Counsel shall be full and complete authorization and protection in
         respect of any action taken or suffered or omitted by it hereunder in
         good faith and in accordance therewith;

                (c) The Trustee shall be under no obligation to exercise any of
         the trusts or powers vested in it by this Agreement, other than its
         obligation to give notice pursuant to this Agreement, or to institute,
         conduct or defend any litigation hereunder or in relation hereto at the
         request, order or direction of any of the Certificateholders, pursuant
         to the provisions of this Agreement, unless such Certificateholders
         shall have offered to the Trustee security or indemnity satisfactory to
         it against the costs, expenses and liabilities which may be incurred
         therein or thereby; nothing contained herein shall, however, relieve
         the Trustee of the obligation, upon the occurrence of an Event of
         Default of which a Responsible Office of the Trustee's corporate trust
         department has actual knowledge (which has not been waived or cured),
         to exercise such of the rights and powers vested in it by this
         Agreement, and to use the same degree of care and skill in their
         exercise as a prudent man would exercise or use under the circumstances
         in the conduct of his own affairs;

<PAGE>



                (d) The Trustee shall not be liable for any action taken,
         suffered or omitted by it in good faith and believed by it to be
         authorized or within the discretion or rights or powers conferred upon
         it by this Agreement;

                (e) Prior to the occurrence of an Event of Default hereunder and
         after the curing or waiver of all Events of Default which may have
         occurred, the Trustee shall not be bound to make any investigation into
         the facts or matters stated in any resolution, certificate, statement,
         instrument, opinion, report, notice, request, consent, order, approval,
         bond or other paper or document, unless requested in writing to do so
         by the Holders of Certificates entitled to at least 25% of the Voting
         Rights; provided, however, that if the payment within a reasonable time
         to the Trustee of the costs, expenses or liabilities likely to be
         incurred by it in the making of such investigation is, in the opinion
         of the Trustee, reasonably assured to the Trustee by the security
         afforded to it by the terms of this Agreement reasonable expense of
         every such examination shall be paid by the Certificateholders
         requesting the investigation;

                (f) The Trustee may execute any of the trusts or powers
         hereunder or perform any duties hereunder either directly or by or
         through agents, nominees, custodians or attorneys appointed with due
         care, and shall not be responsible for any willful misconduct or
         negligence on the part of any agent, attorney, custodian or nominee so
         appointed;

                (g) The Trustee shall not be required to give any bond or surety
         with respect to the execution of the trust created hereby or the powers
         granted hereunder; and

                (h) Whenever in the administration of the provisions of this
         Agreement the Trustee shall deem it necessary or desirable that a
         matter be proved or established prior to taking or suffering any action
         to be taken hereunder, such matter (unless other evidence in respect
         thereof be herein specifically prescribed) may, in the absence of gross
         negligence or bad faith on the part of the Trustee, be deemed to be
         conclusively proved and established by a certificate signed and
         delivered to the Trustee and such certificate, in the absence of gross
         negligence or bad faith on the part of the Trustee, shall be full
         warrant to the Trustee for any action taken, suffered or omitted by it
         under the provisions of this Agreement upon the faith thereof.

                  SECTION 8.03.             Trustee Not Liable for Certificates
                                            or Mortgage Loans.

                  The recitals contained herein and in the Certificates (other
than the signature of the Trustee, the authentication of the Trustee on the
Certificates, the acknowledgments of the Trustee contained in Article II) shall
be taken as the statements of the Company and the Trustee assumes no
responsibility for their correctness. The Trustee makes no representations or
warranties as to the validity or sufficiency of this Agreement or of the
Certificates (other than the signature and authentication of the Trustee on the
Certificates) or of any Mortgage Loan or related document. The Trustee shall not
be accountable for the use or application by the Company of any of the
Certificates or of the proceeds of such Certificates, or for the use or
application of any funds paid to the


                                       102

Company or the Master Servicer in respect of the Mortgage Loans or deposited in
or withdrawn from the Custodial Account by the Master Servicer.

                  SECTION 8.04.             Trustee May Own Certificates.

                  The Trustee in its individual or any other capacity (other
than as Trustee hereunder) may become the owner or pledgee of Certificates with
the same rights it would have if it were not Trustee and may otherwise deal with
the parties hereto.

                  SECTION 8.05.             Trustee's Fees.

                  On each Distribution Date, the Trustee shall be entitled to
withdraw from the Certificate Account as compensation hereunder the Trustee
Fees. Such compensation (which shall not be limited by any provision of law in
regard to the compensation of a trustee of an express trust) shall be paid for
all services rendered by it (except as otherwise reimbursed by the Seller
pursuant to a separate fee letter between the Seller and the Trustee) in the
execution of the trusts hereby created and in the exercise and performance of
any of the powers and duties hereunder or of the Trustee. Except as otherwise
provided in this Agreement, the Trustee and any director, officer, employee or
agent of the Trustee shall be indemnified and held harmless by the Trust Fund
against any claim, loss, liability, fee or expense incurred in connection with
any Event of Default, any breach of this Agreement or any claim or legal action
(including any pending or threatened claim or legal action) relating to the
acceptance or administration of its trusts hereunder or the Certificates, other
than any claim, loss, liability or expense (i) sustained in connection with this
Agreement related to the willful misfeasance, bad faith or negligence of the
Master Servicer in the performance of its duties hereunder or (ii) incurred in
connection with a breach constituting willful misfeasance, bad faith or
negligence of the Trustee in the performance of its duties hereunder or by
reason of reckless disregard of its obligations and duties hereunder.

                  The Master Servicer shall indemnify the Trustee and any
director, officer, employee or agent of the Trustee against any such claim or
legal action (including any pending or threatened claim or legal action), loss,
liability, fee or expense that may be sustained in connection with this
Agreement related to the willful misfeasance, bad faith, or negligence in the
performance of the Master Servicer's duties hereunder.

                  The provisions of this Section 8.05 shall survive the
resignation or removal of the Trustee or the termination of this Agreement.

                  SECTION 8.06.             Eligibility Requirements for
                                            Trustee.

                  The Trustee hereunder shall at all times be a corporation or a
national banking association organized and doing business under the laws of any
state or the United States of America or the District of Columbia, authorized
under such laws to exercise corporate trust powers, having a combined capital
and surplus of at least $50,000,000 and subject to supervision or examination by
federal or state authority. In addition, the Trustee shall at all times be
acceptable to the Rating


                                       103

<PAGE>



Agency rating the Certificates. If such corporation publishes reports of
condition at least annually, pursuant to law or to the requirements of the
aforesaid supervising or examining authority, then for the purposes of this
Section the combined capital and surplus of such corporation shall be deemed to
be its combined capital and surplus as set forth in its most recent report of
condition so published. In case at any time the Trustee shall cease to be
eligible in accordance with the provisions of this Section, the Trustee shall
resign immediately in the manner and with the effect specified in Section 8.07.
The corporation or national banking association serving as Trustee may have
normal banking and trust relationships with the Seller and their affiliates or
the Master Servicer and its affiliates; provided, however, that such corporation
cannot be an affiliate of the Master Servicer other than the Trustee in its role
as successor to the Master Servicer.

                  SECTION 8.07.             Resignation and Removal of the
                                            Trustee.

                  The Trustee may at any time resign and be discharged from the
trusts hereby created by giving written notice thereof to the Master Servicer;
with a copy to the Rating Agencies; provided, that such resignation shall not be
effective until a successor trustee is appointed and accepts appointment in
accordance with the following provisions; provided, however, that the resigning
Trustee shall not resign and be discharged from the trusts hereby created until
such time as the Rating Agency rating the Certificates approves the successor
trustee. Upon receiving such notice of resignation, the Master Servicer shall
promptly appoint a successor trustee who meets the eligibility requirements of
Section 8.06 by written instrument, in triplicate, one copy of which instrument
shall be delivered to each of the resigning Trustee and to the successor
trustee. If no successor trustee shall have been so appointed and have accepted
appointment within 30 days after the giving of such notice of resignation, the
resigning Trustee may petition any court of competent jurisdiction for the
appointment of a successor trustee.

                  If at any time the Trustee shall cease to be eligible in
accordance with the provisions of Section 8.06 and shall fail to resign after
written request therefor by the Master Servicer, or if at any time the Trustee
shall become incapable of acting, or shall be adjudged bankrupt or insolvent, or
a receiver of the Trustee or of its property shall be appointed, or any public
officer shall take charge or control of the Trustee or of its property or
affairs for the purpose of rehabilitation, conservation or liquidation, the
Master Servicer may remove the Trustee and appoint a successor trustee who meets
the eligibility requirements of Section 8.06 by written instrument, in
triplicate, which instrument shall be delivered to the Trustee so removed and to
the successor trustee.

                  The Holders of Certificates entitled to at least 51% of the
Voting Rights, may at any time remove the Trustee and appoint a successor
trustee by written instrument or instruments, in triplicate, signed by such
Holders or their attorneys-in-fact duly authorized, one complete set of which
instruments shall be delivered to the Master Servicer, one complete set to the
Trustee so removed and one complete set to the successor so appointed. A copy of
such instrument shall be delivered to the Certificateholders and the Company by
the Master Servicer.

                  Any resignation or removal of the Trustee and appointment of a
successor trustee pursuant to any of the provisions of this Section shall not
become effective until acceptance of appointment by the successor trustee as
provided in Section 8.08.

                  SECTION 8.08.             Successor Trustee.

                  Any successor trustee appointed as provided in Section 8.07
shall execute, acknowledge and deliver to the Master Servicer and to its
predecessor trustee an instrument accepting such appointment hereunder, and
thereupon the resignation or removal of the predecessor trustee shall become
effective and such successor trustee, without any further act, deed or
conveyance, shall become fully vested with all the rights, powers, duties and
obligations of its predecessor hereunder, with the like effect as if originally
named as trustee herein. The predecessor trustee shall after payment of its
outstanding fees and expenses, promptly deliver to the successor trustee all
assets and records of the Trust Fund held by it hereunder, and the Master
Servicer and the predecessor trustee shall execute and deliver all such
instruments and do such other things as may reasonably be required for more
fully and certainly vesting and confirming in the successor trustee all such
rights, powers, duties and obligations.

                  No successor trustee shall accept appointment as provided in
this Section unless at the time of such acceptance such successor trustee shall
be eligible under the provisions of Section 8.06.

                  Upon acceptance of appointment by a successor trustee as
provided in this Section, the Master Servicer shall mail notice of the
succession of such trustee hereunder to all Holders of Certificates at their
addresses as shown in the Certificate Register. If the Master Servicer fails to
mail such notice within ten days after acceptance of appointment by the
successor trustee, the successor trustee shall cause such notice to be mailed at
the expense of the Master Servicer.

                  SECTION 8.09.             Merger or Consolidation of Trustee.

                  Any state bank or trust company or corporation or national
banking association into which the Trustee may be merged or converted or with
which it may be consolidated or any state bank or trust company or national
banking association resulting from any merger, conversion or consolidation to
which the Trustee shall be a party, or any state bank or trust company or
corporation or national banking association succeeding to all or substantially
all of the corporate trust business of the Trustee, shall be the successor of
the Trustee hereunder, provided such state bank or trust company or corporation
or national banking association shall be eligible under the provisions of
Section 8.06 without the execution or filing of any paper or any further act on
the part of any of the parties hereto, anything herein to the contrary
notwithstanding.

                  SECTION 8.10.             Appointment of Co-Trustee or
                                            Separate Trustee.

                  Notwithstanding any other provisions hereof, at any time, for
the purpose of meeting any legal requirements of any jurisdiction in which any
part of the Trust Fund or property securing


                                       105

the same may at the time be located, the Master Servicer and the Trustee acting
jointly shall have the power and shall execute and deliver all instruments to
appoint one or more Persons approved by the Trustee to act as co-trustee or
co-trustees, jointly with the Trustee, or separate trustee or separate trustees,
of all or any part of the Trust Fund, and to vest in such Person or Persons, in
such capacity, such title to the Trust Fund, or any part thereof, and, subject
to the other provisions of this Section 8.10, such powers, duties, obligations,
rights and trusts as the Master Servicer and the Trustee may consider necessary
or desirable. If the Master Servicer shall not have joined in such appointment
within 15 days after the receipt by it of a request so to do, or in case an
Event of Default shall have occurred and be continuing, the Trustee alone shall
have the power to make such appointment without the Master Servicer. No
co-trustee or separate trustee hereunder shall be required to meet the terms of
eligibility as a successor trustee under Section 8.06 hereunder and no notice to
Holders of Certificates of the appointment of co-trustee(s) or separate
trustee(s) shall be required under Section 8.08 hereof.

                  In the case of any appointment of a co-trustee or separate
trustee pursuant to this Section 8.10 all rights, powers, duties and obligations
conferred or imposed upon the Trustee and required to be conferred or such
co-trustee shall be conferred or imposed upon and exercised or performed by the
Trustee and such separate trustee or co-trustee jointly, except to the extent
that under any law of any jurisdiction in which any particular act or acts are
to be performed (whether as Trustee hereunder or as successor to the Master
Servicer hereunder), the Trustee shall be incompetent or unqualified to perform
such act or acts, in which event such rights, powers, duties and obligations
(including the holding of title to the Trust Fund or any portion thereof in any
such jurisdiction) shall be exercised and performed by such separate trustee or
co-trustee at the direction of the Trustee.

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

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

                                   TERMINATION

                  SECTION 9.01.             Termination Upon Repurchase or
                                            Liquidation of All Mortgage Loans or
                                            upon Purchase of Certificates.

         (a) Subject to Section 9.03, the respective obligations and
responsibilities of the Company, the Master Servicer and the Trustee created
hereby (other than the obligations of the Master Servicer to the Trustee
pursuant to Section 8.05 and of the Master Servicer to provide for and the
Trustee to make payments to Certificateholders as hereafter set forth) shall
terminate upon payment to the Certificateholders of all amounts held by or on
behalf of the Trustee and required to be paid to them hereunder following the
earlier to occur of (i) the repurchase by the Holder of a 50.01% Percentage
Interest in the Class C Certificates (the "Majority Class C Certificateholders")
or its designee of all Mortgage Loans and each REO Property in respect thereof
remaining in the Trust Fund at a price equal to (a) 100% of the unpaid principal
balance of each Mortgage Loan (other than one as to which a REO Property was
acquired) on the day of repurchase together with accrued interest on such unpaid
principal balance at the Net Mortgage Rate to the first day of the month in
which the proceeds of such repurchase are to be distributed, plus (b) the
appraised value of any REO Property (but not more than the unpaid principal
balance of the related Mortgage Loan, together with accrued interest on that
balance at the Net Mortgage Rate to the first day of the month such repurchase
price is distributed), less the good faith estimate of the Majority Class C
Certificateholders of liquidation expenses to be incurred in connection with its
disposal thereof, such appraisal to be conducted by an appraiser mutually agreed
upon by the Majority Class C Certificateholders and the Trustee at the expense
of the Master Servicer, and (ii) the final payment or other liquidation (or any
Advance with respect thereto) of the last Mortgage Loan remaining in the Trust
Fund (or the disposition of all REO Property in respect thereof); provided,
however, that in no event shall the trust created hereby continue beyond the
earlier of (i) the Distribution Date occurring in January 2031 and (ii) the
expiration of 21 years from the death of the last survivor of the descendants of
Joseph P. Kennedy, the late ambassador of the United States to the Court of St.
James, living on the date hereof, and provided further that the purchase price
set forth above shall be increased as is necessary, as determined by the
Majority Class C Certificateholders, to avoid disqualification of either REMIC
1, REMIC 2 or REMIC 3 as a REMIC. In the case of any repurchase by the Majority
Class C Certificateholders pursuant to clause (i), shall exercise reasonable
efforts to cooperate fully with the Trustee in effecting such repurchase and the
transfer of the Mortgage Loans and related Mortgage Files and related records to
the Majority Class C Certificateholders.

                  The right of the Majority Class C Certificateholders or its
designee to repurchase all Mortgage Loans pursuant to (i) above shall be
conditioned upon the aggregate Stated Principal Balance of such Mortgage Loans
at the time of any such repurchase aggregating an amount equal to or less than
10% of the aggregate Stated Principal Balance of the Mortgage Loans at the
Cut-off Date. If such right is exercised, the Majority Class C
Certificateholders upon such repurchase shall provide to the Trustee, notice of
such exercise prior to the Determination Date in the month preceding the month
of purchase and the certification required by Section 3.16.


                                       107

<PAGE>



                  Written notice of any termination, specifying the Distribution
Date upon which the Certificateholders may surrender their Certificates to the
Trustee for payment of the final distribution and cancellation, shall be given
promptly by the Trustee by letter to the Certificateholders mailed (a) in the
event such notice is given in connection with the Majority Class C
Certificateholder's election to repurchase, not earlier than the 15th day and
not later than the 25th day of the month next preceding the month of such final
distribution or (b) otherwise during the month of such final distribution on or
before the Determination Date in such month, in each case specifying (i) the
Distribution Date upon which final payment of the Certificates will be made upon
presentation and surrender of Certificates at the office of the Trustee therein
designated, (ii) the amount of any such final payment and (iii) that the Record
Date otherwise applicable to such Distribution Date is not applicable, payments
being made only upon presentation and surrender of the Certificates at the
office of the Trustee therein specified. In the event such notice is given in
connection with the Majority Class C Certificateholder or its designee's
election to repurchase, the Majority Class C Certificateholder or its designee
shall deliver to the Trustee for deposit in the Certificate Account on the
Business Day immediately preceding the Distribution Date specified in such
notice an amount equal to the above-described repurchase price payable out of
its own funds. Upon presentation and surrender of the Certificates by the
Certificateholders, the Trustee shall first, pay itself the Trustee's Fees for
such Distribution Date and any other amounts owing to the Trustee under this
Agreement, and second, distribute to the Certificateholders (i) the amount
otherwise distributable on such Distribution Date, if not in connection with the
Majority Class C Certificateholder's election to repurchase, or (ii) if the
Majority Class C Certificateholder elected to so repurchase, an amount
determined as follows: with respect to each Regular Certificate (other than the
Class A-IO Certificates), the outstanding Certificate Principal Balance thereof,
plus with respect to each Regular Certificate (other than the Class P
Certificates), one month's interest thereon at the applicable Pass- Through Rate
and any Unpaid Interest Shortfall Amount, plus with respect to each Mezzanine
Certificate, any unpaid Allocated Realized Loss Amount; and with respect to the
Class R Certificates, the Percentage Interest evidenced thereby multiplied by
the difference, if any, between the above described repurchase price and the
aggregate amount to be distributed to the Holders of the Regular Certificates,
subject to the priorities set forth in Section 4.01. Notwithstanding the
foregoing, by acceptance of the Class R Certificates, the Holders of the Class R
Certificates agree, in connection with any termination hereunder, to assign and
transfer any amounts received in respect of such termination to the Holders of
the Class C Certificates and to pay any such amounts to the Holders of the Class
C Certificates. Upon certification to the Trustee by a Servicing Officer,
following such final deposit, the Trustee shall promptly release the Mortgage
Files as directed by the Majority Class C Certificateholder for the remaining
Mortgage Loans, and the Trustee shall execute all assignments, endorsements and
other instruments required by the Majority Class C Certificateholder as being
necessary to effectuate such transfer.

                  In the event that all of the Certificateholders shall not
surrender their Certificates for cancellation within six months after the time
specified in the above-mentioned notice, the Trustee shall give a second notice
to the remaining Certificateholders to surrender their Certificates for
cancellation and receive the final distribution with respect thereto. If within
six months after the second notice all of the Certificates shall not have been
surrendered for cancellation, the Trustee shall take reasonable steps as
directed by the Company in writing, or appoint an agent to take


                                       108

<PAGE>



reasonable steps, to contact the remaining Certificateholders concerning
surrender of their Certificates, and the cost thereof shall be paid out of the
funds and other assets which remain subject hereto. If within nine months after
the second notice all the Certificates shall not have been surrendered for
cancellation, the Class R Certificateholders shall be entitled to all unclaimed
funds and other assets which remain subject hereto.

                  SECTION 9.02.             Termination of REMIC 2 and REMIC 3.

                  REMIC 2 shall be terminated on the earlier of the Final
Distribution Date and the date on which it is deemed to receive the last deemed
distributions on the REMIC 1 Regular Interests and the last distribution due on
the REMIC 2 Regular Interests and the Class R Certificates (in respect of the
Class R-2 Interest) is made. REMIC 3 shall be terminated on the earlier of the
Final Distribution Date and the date on which it is deemed to receive the last
deemed distributions on the REMIC 2 Regular Interests and the last distribution
due on the Regular Certificates and the Class R Certificates (in respect of the
Class R-3 Interest) is made.

                  SECTION 9.03.             Additional Termination Requirements.

                  (a) In the event the Majority Class C Certificateholder
repurchases the Mortgage Loans as provided in Section 9.01, the Trust Fund shall
be terminated in accordance with the following additional requirements, unless
the Majority Class C Certificateholder, at its own expense, obtains for the
Trustee an Opinion of Counsel to the effect that the failure of the Trust Fund
to comply with the requirements of this Section 9.03 will not (i) result in the
imposition on the Trust of taxes on "prohibited transactions," as described in
Section 860F of the Code, or (ii) cause either REMIC 1, REMIC 2 or REMIC 3 to
fail to qualify as a REMIC at any time that any Certificate is outstanding:

                  (i) The Trustee shall establish a 90-day liquidation period
         for REMIC 1, REMIC 2 and REMIC 3, as the case may be, and specify the
         first day of such period in a statement attached to the Trust Fund's
         final Tax Return pursuant to Treasury regulations Section 1.860F-1. The
         Trustee also shall satisfy all of the requirements of a qualified
         liquidation for REMIC 1, REMIC 2 and REMIC 3, as the case may be, under
         Section 860F of the Code and regulations thereunder; and

                  (ii) The Majority Class C Certificateholder shall notify the
         Trustee at the commencement of such 90-day liquidation period and, at
         or prior to the time of making of the final payment on the
         Certificates, the Trustee shall sell or otherwise dispose of all of the
         remaining assets of the Trust Fund in accordance with the terms hereof.

         (b) Each Holder of a Certificate and the Trustee hereby irrevocably
approves and appoints the Master Servicer as its attorney-in-fact to adopt a
plan of complete liquidation for REMIC 1, REMIC 2 and REMIC 3 at the expense of
the Trust Fund in accordance with the terms and conditions of this Agreement.

                                REMIC PROVISIONS

                  SECTION 10.01.            REMIC Administration.

         (a) The Trustee shall make an election to treat the Trust Fund as three
REMICs under the Code and, if necessary, under applicable state law. Each such
election will be made on Form 1066 or other appropriate federal tax or
information return (including Form 8811) or any appropriate state return for the
taxable year ending on the last day of the calendar year in which the
Certificates are issued. For the purposes of the REMIC elections in respect of
the Trust Fund, (i) the Class R-1 Interest will constitute the sole class of
"residual interest" in REMIC 1, (ii) the Class R-2 Interest will constitute the
sole class of "residual interest" in REMIC 2 and (iii) the Class R-3 Interest
will constitute the sole class of "residual interest" in REMIC 3, and the
Regular Certificates shall be designated as the "regular interests" in REMIC 2.
The Master Servicer and the Trustee shall not permit the creation of any
"interests" (within the meaning of Section 860G of the Code) in REMIC 1, REMIC 2
or REMIC 3 other than the REMIC 1 Regular Interests and the Class R-1 Interest
(in the case of REMIC 1) the REMIC 2 Regular Interests and the Class R-2
Interest (in the case of REMIC 2) and the Regular Certificates and the Class R-3
Interest (in the case of REMIC 3). The Trustee will apply for an Employee
Identification Number from the IRS via form SS-4 or any other acceptable method
for each of REMIC 1, REMIC 2 and REMIC 3.

         (b) The Closing Date is hereby designated as the "startup day" of the
Trust Fund within the meaning of Section 860G(a)(9) of the Code.

         (c) The Trustee shall pay out of its own funds, without any right of
reimbursement, any and all expenses relating to any tax audit of the REMICs
(including, but not limited to, any professional fees or any administrative or
judicial proceedings with respect to the REMICs that involve the Internal
Revenue Service or state tax authorities), other than the expense of obtaining
any tax related Opinion of Counsel except as specified herein. The Trustee, as
agent for the REMICs' tax matters person, shall (i) act on behalf of the REMICs
in relation to any tax matter or controversy involving the Trust Fund and (ii)
represent the Trust Fund in any administrative or judicial proceeding relating
to an examination or audit by any governmental taxing authority with respect
thereto. By their acceptance thereof, the holder of the largest Percentage
Interest of the Class R Certificates hereby agrees to irrevocably appoint the
Trustee or an Affiliate as its agent to perform all of the duties of the tax
matters person for the REMICs.

                  (d) The Trustee shall prepare, sign and file all of the Tax
Returns in respect of the REMICs created hereunder. The expenses of preparing
and filing such returns shall be borne by the Trustee without any right of
reimbursement therefor. The Master Servicer shall provide on a timely basis to
the Trustee or its designee such information with respect to the assets of the
REMICs as is in its possession and reasonably required by the Trustee to enable
it to perform its obligations under this Article X.



                                       110

<PAGE>



                  (e) The Trustee shall perform on behalf of the REMICs all
reporting and other tax compliance duties that are the responsibility of the
REMICs under the Code, the REMIC Provisions or other compliance guidance issued
by the Internal Revenue Service or any state or local taxing authority. Among
its other duties, as required by the Code, the REMIC Provisions or other such
compliance guidance, the Trustee shall provide (i) to any Transferor of a Class
R Certificate such information as is necessary for the application of any tax
relating to the transfer of a Class R Certificate to any Person who is not a
Permitted Transferee, (ii) to the Certificateholders such information or reports
as are required by the Code or the REMIC Provisions including reports relating
to interest, original issue discount and market discount or premium (using the
Prepayment Assumption as required) and (iii) to the Internal Revenue Service the
name, title, address and telephone number of the person who will serve as the
representative of the REMICs. The Master Servicer shall provide on a timely
basis to the Trustee such information with respect to the assets of the REMICs,
including, without limitation, the Mortgage Loans, as is in its possession and
reasonably required by the Trustee to enable it to perform its obligations under
this subsection. In addition, the Company shall provide or cause to be provided
to the Trustee, within ten (10) days after the Closing Date, all information or
data that the Trustee reasonably determines to be relevant for tax purposes as
to the valuations and issue prices of the Certificates, including, without
limitation, the price, yield, prepayment assumption and projected cash flow of
the Certificates.

                  (f) The Trustee shall take such action and shall cause the
REMICs created hereunder to take such action as shall be necessary to create or
maintain the status thereof as REMICs under the REMIC Provisions (and the Master
Servicer shall assist it, to the extent reasonably requested by it). The Trustee
shall not take any action, cause the Trust Fund to take any action or fail to
take (or fail to cause to be taken) any action that, under the REMIC Provisions,
if taken or not taken, as the case may be, could (i) endanger the status of the
REMIC 1, REMIC 2 or REMIC 3 as REMICs or (ii) result in the imposition of a tax
upon the REMICs (including but not limited to the tax on prohibited transactions
as defined in Section 860F(a)(2) of the Code and the tax on contributions to a
REMIC set forth in Section 860G(d) of the Code) (either such event, an "Adverse
REMIC Event") unless the Trustee has received an Opinion of Counsel, addressed
to the Trustee (at the expense of the party seeking to take such action but in
no event at the expense of the Trustee) to the effect that the contemplated
action will not, with respect to the REMICs created hereunder, endanger such
status or result in the imposition of such a tax, nor shall the Master Servicer
take or fail to take any action (whether or not authorized hereunder) as to
which the Trustee has advised it in writing that it has received an Opinion of
Counsel to the effect that an Adverse REMIC Event could occur with respect to
such action. In addition, prior to taking any action with respect to the REMICs
or the assets of the REMICs, or causing the REMICs to take any action, which is
not contemplated under the terms of this Agreement, the Master Servicer will
consult with the Trustee or its designee, in writing, with respect to whether
such action could cause an Adverse REMIC Event to occur with respect to the
Trust Fund, and the Master Servicer shall not take any such action or cause the
Trust Fund to take any such action as to which the Trustee has advised it in
writing that an Adverse REMIC Event could occur. The Trustee may consult with
counsel to make such written advice, and the cost of same shall be borne by the
party seeking to take the action not permitted by this Agreement, but in no
event shall such cost be an expense of the Trustee. At all times as may be
required by the Code, the Trustee will ensure that substantially all of the
assets


                                       111

<PAGE>



of the REMICs created hereunder will consist of "qualified mortgages" as defined
in Section 860G(a)(3) of the Code and "permitted investments" as defined in
Section 860G(a)(5) of the Code.

                  (g) In the event that any tax is imposed on "prohibited
transactions" of the REMICs created hereunder as defined in Section 860F(a)(2)
of the Code, on the "net income from foreclosure property" of the REMICs as
defined in Section 860G(c) of the Code, on any contributions to the REMICs after
the Startup Day therefor pursuant to Section 860G(d) of the Code, or any other
tax is imposed by the Code or any applicable provisions of state or local tax
laws, such tax shall be charged (i) to the Trustee pursuant to Section 10.03
hereof, if such tax arises out of or results from a breach by the Trustee of any
of its obligations under this Article X, (ii) to the Master Servicer pursuant to
Section 10.03 hereof, if such tax arises out of or results from a breach by the
Master Servicer of any of its obligations under Article III or this Article X,
or otherwise, (iii) to the Master Servicer as provided in Section 3.05 and (iv)
against amounts on deposit in the Certificate Account and shall be paid by
withdrawal therefrom to the extent not required to be paid by the Master
Servicer or the Trustee pursuant to another provision of this Agreement.

                  (h) On or before April 15 of each calendar year, commencing
April 15, 2001, the Trustee shall deliver to the Master Servicer and the Rating
Agency a Certificate from a Responsible Officer of the Trustee stating the
Trustee's compliance with this Article X.

                  (i) The Trustee shall, for federal income tax purposes,
maintain books and records with respect to the REMICs on a calendar year and on
an accrual basis.

                  (j) Following the Startup Day, the Trustee shall not accept
any contributions of assets to the REMICs other than in connection with any
Qualified Substitute Mortgage Loan delivered in accordance with Section 2.04
unless it shall have received an Opinion of Counsel to the effect that the
inclusion of such assets in the REMICs will not cause the REMIC 1, REMIC 2 or
REMIC 3 to fail to qualify as REMICs at any time that any Certificates are
outstanding or subject either REMIC 1, REMIC 2 or REMIC 3 to any tax under the
REMIC Provisions or other applicable provisions of federal, state and local law
or ordinances.

                  (k) Neither the Trustee nor the Master Servicer shall enter
into any arrangement by which the REMICs will receive a fee or other
compensation for services nor permit the REMICs to receive any income from
assets other than "qualified mortgages" as defined in Section 860G(a)(3) of the
Code or "permitted investments" as defined in Section 860G(a)(5) of the Code.

                  SECTION 10.02.            Prohibited Transactions and
                                            Activities.

                  None of the Company, the Master Servicer or the Trustee shall
sell, dispose of or substitute for any of the Mortgage Loans (except in
connection with (i) the foreclosure of a Mortgage Loan, including but not
limited to, the acquisition or sale of a Mortgaged Property acquired by deed in
lieu of foreclosure, (ii) the bankruptcy of the Trust Fund, (iii) the
termination of REMIC 1, REMIC 2 or REMIC 3 pursuant to Article IX of this
Agreement, (iv) a substitution pursuant to Article II of this Agreement or (v) a
purchase of Mortgage Loans pursuant to Article II or III of this


                                       112

Agreement), nor acquire any assets for the Trust Fund (other than REO Property
acquired in respect of a defaulted Mortgage Loan), nor sell or dispose of any
investments in the Custodial Account or the Certificate Account for gain, nor
accept any contributions to the REMICs after the Closing Date (other than a
Qualified Substitute Mortgage Loan delivered in accordance with Section 2.03),
unless it has received an Opinion of Counsel, addressed to the Trustee (at the
expense of the party seeking to cause such sale, disposition, substitution,
acquisition or contribution but in no event at the expense of the Trustee) that
such sale, disposition, substitution, acquisition or contribution will not (a)
affect adversely the status of REMIC 1, REMIC 2 or REMIC 3 as REMICs or (b)
cause the Trust Fund to be subject to a tax on "prohibited transactions" or
"contributions" pursuant to the REMIC Provisions.

                  SECTION 10.03.            Master Servicer and Trustee
                                            Indemnification.

                  (a) The Trustee agrees to indemnify the Trust Fund, the
Company, and the Master Servicer for any taxes and costs including, without
limitation, any reasonable attorneys fees imposed on or incurred by the Trust
Fund, the Company or the Master Servicer, as a result of a breach of the
Trustee's covenants set forth in this Article X.

                  (b) The Master Servicer agrees to indemnify the Trust Fund,
the Company and the Trustee for any taxes and costs including, without
limitation, any reasonable attorneys' fees imposed on or incurred by the Trust
Fund, the Company or the Trustee, as a result of a breach of the Master
Servicer's covenants set forth in Article III or this Article X, in each case
with respect to compliance with the REMIC Provisions.

                  SECTION 11.01.            Amendment.

                  This Agreement may be amended from time to time by the
Company, the Master Servicer and the Trustee, without the consent of any of the
Certificateholders, (i) to cure any ambiguity, (ii) to correct or supplement any
provisions herein which may be defective or inconsistent with any other
provisions herein or to correct any error, (iii) to amend this Agreement in any
respect subject to the provisions in clauses (A) and (B) below, or (iv) if such
amendment, as evidenced by an Opinion of Counsel (provided by the Person
requesting such amendment) delivered to the Trustee, is reasonably necessary to
comply with any requirements imposed by the Code or any successor or amendatory
statute or any temporary or final regulation, revenue ruling, revenue procedure
or other written official announcement or interpretation relating to federal
income tax laws or any proposed such action which, if made effective, would
apply retroactively to the Trust Fund at least from the effective date of such
amendment; provided that such action (except any amendment described in (iv)
above) shall not adversely affect in any material respect the interests of any
Certificateholder (other than Certificateholders who shall consent to such
amendment), as evidenced by (A) an Opinion of Counsel (provided by the Person
requesting such amendment) delivered to the Trustee, and (B) a letter from each
Rating Agency, confirming that such amendment shall not cause it to lower its
rating on any of the Certificates.

                  This Agreement may also be amended from time to time by the
Company, the Master Servicer and the Trustee and Holders of Certificates
entitled to at least 66-2/3% of the Voting Rights for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions of
this Agreement or of modifying in any manner the rights of the Holders of
Certificates; provided, however, that no such amendment shall (i) reduce in any
manner the amount of, or delay the timing of, payments received on Mortgage
Loans which are required to be distributed on any Certificate without the
consent of the Holder of such Certificate, (ii) adversely affect in any material
respect the interests of the Holders of any Class of Certificates in a manner
other than as described in (i), without the consent of the Holders of
Certificates of such Class evidencing at least 66-2/3% of the Voting Rights of
such Class, or (iii) reduce the aforesaid percentage of Certificates the Holders
of which are required to consent to any such amendment, without the consent of
the Holders of all Certificates then outstanding. Notwithstanding any other
provision of this Agreement, for purposes of the giving or withholding of
consents pursuant to this Section 11.01, Certificates registered in the name of
the Seller or the Master Servicer or any affiliate thereof shall be entitled to
Voting Rights with respect to matters described in (i), (ii) and (iii) of this
paragraph.

                  Notwithstanding any contrary provision of this Agreement, the
Trustee shall not consent to any amendment to this Agreement unless it shall
have first received an Opinion of Counsel (provided by the Person requesting
such amendment) to the effect that such amendment will not result in the
imposition of any tax on either REMIC 1, REMIC 2 or REMIC 3 pursuant to the


                                       114

<PAGE>



REMIC Provisions or cause either REMIC 1, REMIC 2 or REMIC 3 to fail to qualify
as a REMIC at any time that any Certificates are outstanding.

                  Promptly after the execution of any such amendment the Trustee
shall furnish a copy of such amendment or a written statement describing the
amendment to each Certificateholder, with a copy to the Rating Agencies.

                  It shall not be necessary for the consent of
Certificateholders under this Section 11.01 to approve the particular form of
any proposed amendment, but it shall be sufficient if such consent shall approve
the substance thereof. The manner of obtaining such consents and of evidencing
the authorization of the execution thereof by Certificateholders shall be
subject to such reasonable regulations as the Trustee may prescribe.

                  Prior to executing any amendment pursuant to this Section, the
Trustee shall be entitled to receive an Opinion of Counsel (provided by the
Person requesting such amendment) to the effect that such amendment is
authorized or permitted by this Agreement. The cost of any Opinion of Counsel
delivered pursuant to this Section 11.01 shall be an expense of the party
requesting such amendment, but in any case shall not be an expense of the
Trustee.

                  The Trustee may, but shall not be obligated to enter into any
amendment pursuant to this Section that affects its rights, duties and
immunities under this Agreement or otherwise.

                  SECTION 11.02.            Recordation of Agreement;
                                            Counterparts.

                  To the extent permitted by applicable law, this Agreement is
subject to recordation in all appropriate public offices for real property
records in all the counties or other comparable jurisdictions in which any or
all of the properties subject to the Mortgages are situated, and in any other
appropriate public recording office or elsewhere, such recordation to be
effected by the Master Servicer at the expense of the Certificateholders, but
only upon direction of the Company accompanied by an Opinion of Counsel to the
effect that such recordation materially and beneficially affects the interests
of the Certificateholders.

                  For the purpose of facilitating the recordation of this
Agreement as herein provided and for other purposes, this Agreement may be
executed simultaneously in any number of counterparts, each of which
counterparts shall be deemed to be an original, and such counterparts shall
constitute but one and the same instrument.

                  SECTION 11.03.            Limitation on Rights of
                                            Certificateholders.

                  The death or incapacity of any Certificateholder shall not
operate to terminate this Agreement or the Trust Fund, nor entitle such
Certificateholder's legal representatives or heirs to claim an accounting or to
take any action or proceeding in any court for a partition or winding up of the
Trust Fund, nor otherwise affect the rights, obligations and liabilities of the
parties hereto or any of them.

                  No Certificateholder shall have any right to vote (except as
expressly provided for herein) or in any manner otherwise control the operation
and management of the Trust Fund, or the obligations of the parties hereto, nor
shall anything herein set forth, or contained in the terms of the Certificates,
be construed so as to constitute the Certificateholders from time to time as

any liability to any third party by reason of any action taken by the parties to
this Agreement pursuant to any provision hereof.

                  No Certificateholder shall have any right by virtue of any

Default, or of a default by the Seller or the Trustee in the performance of any
obligation hereunder, and of the continuance thereof, as hereinbefore provided,
and unless also the Holders of Certificates entitled to at least 51% of the
Voting Rights shall have made written request upon the Trustee to institute such
action, suit or proceeding in its own name as Trustee hereunder and shall have
offered to the Trustee such reasonable indemnity as it may require against the
costs, expenses and liabilities to be incurred therein or thereby, and the
Trustee, for 60 days after its receipt of such notice, request and offer of
indemnity, shall have neglected or refused to institute any such action, suit or
proceeding. It is understood and intended, and expressly covenanted by each
Certificateholder with every other Certificateholder and the Trustee, that no
one or more Holders of Certificates shall have any right in any manner whatever
by virtue of any provision of this Agreement to affect, disturb or prejudice the
rights of the Holders of any other of such Certificates, or to obtain or seek to
obtain priority over or preference to any other such Holder, or to enforce any
right under this Agreement, except in the manner herein provided and for the
equal, ratable and common benefit of all Certificateholders. For the protection
and enforcement of the provisions of this Section, each and every
Certificateholder and the Trustee shall be entitled to such relief as can be
given either at law or in equity.

                  This Agreement and the Certificates shall be construed in
accordance with the laws of the State of New York and the obligations, rights
and remedies of the parties hereunder shall be determined in accordance with

         evidencing a percentage interest in the distributions allocable to the
         Class A-__ Certificates with respect to a Trust Fund consisting
         primarily of a pool of conforming one- to four-family fixed-rate first
         lien mortgage loans formed and sold by IMPAC SECURED ASSETS CORP.

         This Certificate is payable solely from the assets of the Trust Fund,
and does not represent an obligation of or interest in Impac Secured Assets
Corp., the Master Servicer, the Trustee referred to below or any of their
affiliates. Neither this Certificate nor the underlying Mortgage Loans are
guaranteed or insured by any governmental agency or instrumentality or by Impac
Secured Assets Corp., the Master Servicer, the Trustee or any of their
affiliates. None of the Company, the Master Servicer or any of their affiliates
will have any obligation with respect to any certificate or other obligation
secured by or payable from payments on the Certificates.

         This certifies that Cede & Co. is the registered owner of the
Percentage Interest evidenced by this Certificate (obtained by dividing the
Initial [Certificate Principal Balance] [Notional Amount] of this Certificate by
the aggregate Initial [Certificate Principal Balance] [Notional Amount] of all
Class A-___ Certificates, both as specified above) in certain distributions with
respect to the Trust Fund consisting primarily of an interest in a pool of
conventional one- to four-family fixed-rate first lien mortgage loans (the
"Mortgage Loans"), formed and sold by Impac Secured Assets Corp. (hereinafter
called the "Company," which term includes any successor entity under the
Agreement


                                       A-2

referred to below). The Trust Fund was created pursuant to a Pooling and
Servicing Agreement dated as specified above (the "Agreement") among the
Company, the Master Servicer and Bankers Trust Company of California, N.A., as
trustee (the "Trustee"), a summary of certain of the pertinent provisions of
which is set forth hereafter. To the extent not defined herein, the capitalized
terms used herein have the meanings assigned in the Agreement. This Certificate
is issued under and is subject to the terms, provisions and conditions of the
Agreement, to which Agreement the Holder of this Certificate by virtue of the
acceptance hereof assents and by which such Holder is bound.

         Pursuant to the terms of the Agreement, a distribution will be made on
the 25th day of each month or, if such 25th day is not a Business Day, the
Business Day immediately following (the "Distribution Date"), commencing as
described in the Agreement, to the Person in whose name this Certificate is
registered at the close of business on the last Business Day of the month
immediately preceding the month of such Distribution Date (the "Record Date"),
from the Available Distribution Amount in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount of [interest
and] [principal], if any, required to be distributed to Holders of Class A-__
Certificates on such Distribution Date.

         Distributions on this Certificate will be made either by the Trustee or
by a Paying Agent appointed by the Trustee either in immediately available funds
(by wire transfer or otherwise) for the account of the Person entitled thereto
if such Person shall have so notified the Trustee or such Paying Agent at least
5 Business Days prior to the related Record Date, or by check mailed to the
address of the Person entitled thereto, as such name and address shall appear on
the Certificate Register.

         Notwithstanding the above, the final distribution on this Certificate
will be made after due notice of the pendency of such distribution and only upon
presentation and surrender of this Certificate at the office or agency appointed
by the Trustee for that purpose in the City and State of New York. The Initial
[Certificate Principal Balance] [Notional Amount] of this Certificate is set
forth above. The [Certificate Principal Balance] [Notional Amount] hereof will
be reduced to the extent of [distributions allocable to principal and] any
Realized Losses allocable hereto.

         This Certificate is one of a duly authorized issue of Certificates
issued in several Classes designated as Mortgage Pass-Through Certificates of
the Series specified hereon (herein collectively called the "Certificates").

         The Certificates are limited in right of payment to certain collections
and recoveries respecting the Mortgage Loans, all as more specifically set forth
herein and in the Agreement. In the event Master Servicer funds are advanced
with respect to any Mortgage Loan, such advance is reimbursable to the Master
Servicer, to the extent provided in the Agreement, from related recoveries on
such Mortgage Loan or from other cash that would have been distributable to
Certificateholders.

         As provided in the Agreement, withdrawals from the Custodial Account
and/or the Certificate Account created for the benefit of Certificateholders may
be made by the Master Servicer


                                       A-3

<PAGE>



from time to time for purposes other than distributions to Certificateholders,
such purposes including without limitation reimbursement to the Trustee, the
Company and the Master Servicer of advances made, or certain expenses incurred,
by either of them.

         The Agreement permits, with certain exceptions therein provided, the
amendment of the Agreement and the modification of the rights and obligations of
the Company, the Master Servicer and the Trustee and the rights of the
Certificateholders under the Agreement at any time by the Company, the Master
Servicer and the Trustee with the consent of the Holders of Certificates
evidencing in the aggregate not less than 66-2/3% of the Percentage Interests of
each Class of Certificates affected thereby. Any such consent by the Holder of
this Certificate shall be conclusive and binding on such Holder and upon all
future holders of this Certificate and of any Certificate issued upon the
transfer hereof or in exchange herefor or in lieu hereof whether or not notation
of such consent is made upon the Certificate. The Agreement also permits the
amendment thereof in certain circumstances without the consent of the Holders of
any of the Certificates and, in certain additional circumstances, without the
consent of the Holders of certain Classes of Certificates.

         As provided in the Agreement and subject to certain limitations therein
set forth, the transfer of this Certificate is registrable in the Certificate
Register upon surrender of this Certificate for registration of transfer at the
offices or agencies appointed by the Trustee, duly endorsed by, or accompanied
by an assignment in the form below or other written instrument of transfer in
form satisfactory to the Trustee and the Certificate Registrar duly executed by
the Holder hereof or such Holder's attorney duly authorized in writing, and
thereupon one or more new Certificates of authorized denominations evidencing
the same Class and aggregate Percentage Interest will be issued to the
designated transferee or transferees.

         The Certificates are issuable only as registered Certificates without

Registrar and any agent of the Company, the Master Servicer, the Trustee or the
Certificate Registrar may treat the Person in whose name this Certificate is
registered as the owner hereof for all purposes, and neither the Company, the

         The obligations created by the Agreement in respect of the Certificates
and the Trust Fund created thereby shall terminate upon the payment to
Certificateholders of all amounts held by or on behalf of the Trustee and

(i) the purchase by the Master Servicer or the Company from the Trust Fund of
all remaining Mortgage Loans and each REO Property in respect thereof remaining
in the Trust Fund, thereby effecting early retirement of the Certificates and
(ii) the final payment or other liquidation (or any Advance with respect
thereto) of the last Mortgage Loan remaining in the Trust Fund (or the

determined as provided in the Agreement all remaining Mortgage Loans and all
property acquired in respect of any Mortgage Loan or (ii) purchase in whole, but
not in part, all of the Certificates from the Holders thereof; provided, that
any such option may only be exercised if the aggregate Stated Principal Balance
of the Mortgage Loans as of the Distribution Date upon which the proceeds of any
such purchase are distributed is less than ten percent of the aggregate Stated
Principal Balance of the Mortgage Loans at the Cut-off Date.

         Unless the certificate of authentication hereon has been executed by
the Trustee, by manual signature, this Certificate shall not be entitled to any
benefit under the Agreement or be valid for any purpose.

         evidencing a percentage interest in any distributions allocable to the
         Class [M-__][B] Certificates with respect to the Trust Fund consisting
         primarily of a pool of conforming one- to four-family fixed-rate first
         lien mortgage loans formed and sold by IMPAC SECURED ASSETS CORP.

         This Certificate is payable solely from the assets of the Trust Fund,
and does not represent an obligation of or interest in Impac Secured Assets
Corp., the Master Servicer, the Trustee referred to below or any of their
affiliates. Neither this Certificate nor the underlying Mortgage Loans are
guaranteed or insured by any governmental agency or instrumentality or by Impac
Secured Assets Corp., the Master Servicer, the Trustee or any of their
affiliates. None of the Company, the Master Servicer or any of their affiliates
will have any obligation with respect to any certificate or other obligation
secured by or payable from payments on the Certificates.

Percentage Interest evidenced by this Certificate (obtained by dividing the
Initial [Certificate Principal Balance][Notional Amount] of this Certificate by
the aggregate Initial [Certificate Principal Balance][Notional Amount] of all
Class [M-__][B] Certificates, both as specified above) in certain distributions
with respect to a Trust Fund consisting primarily of a pool of conforming one-
to four-family fixed-rate first lien mortgage loans (the "Mortgage Loans"),
formed and sold by Impac Secured Assets Corp. (hereinafter called the "Company,"
which term includes any successor entity under the Agreement referred to below).
The Trust Fund was created pursuant to a Pooling and Servicing Agreement dated
as specified above


                                      B-1-2

<PAGE>



(the "Agreement") among the Company, the Master Servicer and Bankers Trust
Company of California, N.A., as trustee (the "Trustee"), a summary of certain of
the pertinent provisions of which is set forth hereafter. To the extent not
defined herein, the capitalized terms used herein have the meanings assigned in
the Agreement. This Certificate is issued under and is subject to the terms,
provisions and conditions of the Agreement, to which Agreement the Holder of
this Certificate by virtue of the acceptance hereof assents and by which such
Holder is bound.

         Pursuant to the terms of the Agreement, a distribution will be made on
the 25th day of each month or, if such 25th day is not a Business Day, the
Business Day immediately following (the "Distribution Date"), commencing as
described in the Agreement, to the Person in whose name this Certificate is
registered at the close of business on the last Business Day of the month
immediately preceding the month of such Distribution Date (the "Record Date"),
from the Available Distribution Amount in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount (of interest
[and principal], if any) required to be distributed to Holders of Class [M-
__][B] Certificates on such Distribution Date.

         Distributions on this Certificate will be made either by the Trustee or
by a Paying Agent appointed by the Trustee either in immediately available funds
(by wire transfer or otherwise) for the account of the Person entitled thereto
if such Person shall have so notified the Trustee or such Paying Agent at least
5 Business Days prior to the related Record Date, or by check mailed to the
address of the Person entitled thereto, as such name and address shall appear on
the Certificate Register.

         Notwithstanding the above, the final distribution on this Certificate
will be made after due notice of the pendency of such distribution and only upon
presentation and surrender of this Certificate at the office or agency appointed
by the Trustee for that purpose in the City and State of New York. The Initial
[Certificate Principal Balance][Notional Amount] of this Certificate is set
forth above. The [Certificate Principal Balance][Notional Amount] hereof will be
reduced to the extent of [the distributions allocable to principal and] any
Realized Losses allocable hereto.

         This Certificate is one of a duly authorized issue of Certificates
issued in several Classes designated as Mortgage Pass-Through Certificates of
the Series specified hereon (herein collectively called the "Certificates").

         The Certificates are limited in right of payment to certain collections
and recoveries respecting the Mortgage Loans, all as more specifically set forth
herein and in the Agreement. In the event Master Servicer funds are advanced
with respect to any Mortgage Loan, such advance is reimbursable to the Master
Servicer, to the extent provided in the Agreement, from related recoveries on
such Mortgage Loan or from other cash that would have been distributable to
Certificateholders.

         As provided in the Agreement, withdrawals from the Custodial Account
and/or the Certificate Account created for the benefit of Certificateholders may
be made by the Master Servicer from time to time for purposes other than
distributions to Certificateholders, such purposes including without


                                      B-1-3

<PAGE>



limitation reimbursement to the Trustee, the Company and the Master Servicer of
advances made, or certain expenses incurred, by either of them.

         The Agreement permits, with certain exceptions therein provided, the
amendment of the Agreement and the modification of the rights and obligations of
the Company, the Master Servicer and the Trustee and the rights of the
Certificateholders under the Agreement at any time by the Company, the Master
Servicer and the Trustee with the consent of the Holders of Certificates
evidencing in the aggregate not less than 66-2/3% of the Percentage Interests of
each Class of Certificates affected thereby. Any such consent by the Holder of
this Certificate shall be conclusive and binding on such Holder and upon all
future holders of this Certificate and of any Certificate issued upon the
transfer hereof or in exchange herefor or in lieu hereof whether or not notation
of such consent is made upon the Certificate. The Agreement also permits the
amendment thereof in certain circumstances without the consent of the Holders of
any of the Certificates and, in certain additional circumstances, without the
consent of the Holders of certain Classes of Certificates.

         As provided in the Agreement and subject to certain limitations therein
set forth, the transfer of this Certificate is registrable in the Certificate
Register upon surrender of this Certificate for registration of transfer at the
offices or agencies appointed by the Trustee, duly endorsed by, or accompanied
by an assignment in the form below or other written instrument of transfer in
form satisfactory to the Trustee and the Certificate Registrar duly executed by
the Holder hereof or such Holder's attorney duly authorized in writing, and
thereupon one or more new Certificates of authorized denominations evidencing
the same Class and aggregate Percentage Interest will be issued to the
designated transferee or transferees.

         The Certificates are issuable only as registered Certificates without
coupons in Classes and in denominations specified in the Agreement. As provided
in the Agreement and subject to certain limitations therein set forth,
Certificates are exchangeable for new Certificates of authorized denominations
evidencing the same Class and aggregate Percentage Interest, as requested by the
Holder surrendering the same.

         No service charge will be made for any such registration of transfer or
exchange, but the Trustee may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

         The Company, the Master Servicer, the Trustee and the Certificate
Registrar and any agent of the Company, the Master Servicer, the Trustee or the
Certificate Registrar may treat the Person in whose name this Certificate is
registered as the owner hereof for all purposes, and neither the Company, the
Master Servicer, the Trustee nor any such agent shall be affected by notice to
the contrary.

         This Certificate shall be governed by and construed in accordance with
the laws of the State of New York.

         of a pool of conforming one- to four-family fixed-rate first lien
         mortgage loans formed and sold by IMPAC SECURED ASSETS CORP.

         Principal in respect of this Certificate is distributable monthly as
set forth herein. Accordingly, the Certificate Principal Balance of this Class C
Certificate at any time may be less than the Initial Certificate Principal
Balance set forth on the face hereof, as described herein. This Class C
Certificate does not evidence an obligation of, or an interest in, and is not
guaranteed by the Company, the Master Servicer, or the Trustee referred to below
or any of their respective affiliates.

         This certifies that ____________ is the registered owner of the

Principal Balance) in certain distributions with respect to a Trust consisting

terms, provisions and conditions of the Agreement, to which Agreement the Holder
of this Class C Certificate by virtue of the acceptance hereof assents and by
which such Holder is bound.

         No transfer of a Certificate of this Class shall be made unless such
transfer is made pursuant to an effective registration statement under the Act
and any applicable state securities laws or is exempt from the registration
requirements under said Act and such laws. In the event that a transfer is to be
made in reliance upon an exemption from the Act and such laws, in order to
assure compliance with the Act and such laws, the Certificateholder desiring to

         This Certificate does not evidence an obligation of, or an interest in,
and is not guaranteed by Impac Secured Assets Corp., the Master Servicer or the
Trustee referred to below or any of their respective affiliates.

         This certifies that _____________ is the registered owner of the

have the meanings assigned in the Agreement. This Certificate is issued under
and is subject to the terms, provisions and conditions of the Agreement, to
which Agreement the Holder of this Certificate by virtue of the acceptance

Agreement. In addition, any distribution of the proceeds of any remaining assets
of the Trust will be made only upon presentment and surrender of this

and any applicable state securities laws or is exempt from the registration
requirements under said Act and such laws. In the event that a transfer is to be
made in reliance upon an exemption from the Act and such laws, in order to
assure compliance with the Act and such laws, the Certificateholder desiring to
effect such transfer and such Certificateholder's prospective transferee shall
each certify to the Trustee and the Company in writing the facts surrounding the

desiring to effect such transfer shall, and does hereby agree to, indemnify the
Trustee and the Company against any liability that may result if the transfer is

                       Mortgage Pass-Through Certificates,
                                  Series 2000-4

         This Certificate is one of a duly authorized issue of Certificates
designated as Impac Secured Assets Corp., Mortgage Pass-Through Certificates,
Series 2000-4 (herein collectively called the "Certificates"), and representing
a beneficial ownership interest in the Trust created by the Agreement.

         The Certificateholder, by its acceptance of this Certificate, agrees
that it will look solely to the funds on deposit in the Distribution Account for
payment hereunder and that the Trustee is not liable to the Certificateholders
for any amount payable under this Certificate or the Agreement or, except as
expressly provided in the Agreement, subject to any liability under the
Agreement.

         This Certificate does not purport to summarize the Agreement and
reference is made to the Agreement for the interests, rights and limitations of
rights, benefits, obligations and duties evidenced thereby, and the rights,
duties and immunities of the Trustee.

         Pursuant to the terms of the Agreement, a distribution will be made on
the 25th day of each month or, if such 25th day is not a Business Day then the
first Business Day following such Distribution Date (the "Distribution Date"),
commencing on the first Distribution Date specified on the face hereof, to the
Person in whose name this Certificate is registered at the close of business on
the applicable Record Date in an amount equal to the product of the Percentage
Interest evidenced by this Certificate and the amount required to be distributed
to Holders of Certificates of the Class to which this Certificate belongs on
such Distribution Date pursuant to the Agreement.

         Distributions on this Certificate shall be made by check or money order
mailed to the address of the person entitled thereto as it appears on the
Certificate Register or by wire transfer or otherwise, as set forth in the
Agreement. The final distribution on each Certificate will be made in like
manner, but only upon presentment and surrender of such Certificate at the
office or agency of the Trustee specified in the notice to Certificateholders of
such final distribution.

         The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Trustee and the rights of the Certificateholders under the Agreement at any time
by the Company, the Master Servicer and the Trustee and of Holders of the
requisite percentage of the Percentage Interests of each Class of Certificates
affected by such amendment, as specified in the Agreement. Any such consent by
the Holder of this Certificate shall be conclusive and binding on such Holder
and upon all future Holders of this Certificate and of any Certificate issued
upon the transfer hereof or in exchange therefor or in lieu hereof whether or
not notation of such consent is made upon this Certificate. The Agreement also


                                     B-2-23

<PAGE>



permits the amendment thereof, in certain limited circumstances, without the
consent of the Holders of any of the Certificates.

         As provided in the Agreement and subject to certain limitations therein
set forth, the transfer of this Certificate is registrable in the Certificate
Register of the Trustee upon surrender of this Certificate for registration of
transfer at the office or agency maintained by the Trustee accompanied by a
written instrument of transfer in form satisfactory to the Trustee and the
Certificate Registrar duly executed by the holder hereof or such holder's
attorney duly authorized in writing, and thereupon one or more new Certificates
of the same Class in authorized denominations and evidencing the same aggregate
Percentage Interest in the Trust will be issued to the designated transferee or
transferees.

         The Certificates are issuable only as registered Certificates without
coupons in denominations specified in the Agreement. As provided in the
Agreement and subject to certain limitations therein set forth, Certificates are
exchangeable for new Certificates of the same Class in authorized denominations
and evidencing the same aggregate Percentage Interest, as requested by the
Holder surrendering the same.

         No service charge will be made for any such registration of transfer or
exchange, but the Trustee may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

         The Company, the Master Servicer and the Trustee and any agent of the
Company or the Trustee may treat the Person in whose name this Certificate is
registered as the owner hereof for all purposes, and neither the Company, the
Trustee nor any such agent shall be affected by any notice to the contrary.

         On any Distribution Date following the date at which the remaining
aggregate Principal Balance of the Mortgage Loans is less than 10% of the
aggregate Principal Balance of the Mortgage Loans as of the Cut-off Date, the
Master Servicer may purchase, in whole, from the Trust the Mortgage Loans at a
purchase price determined as provided in the Agreement. In the event that no
such optional termination occurs, the obligations and responsibilities created
by the Agreement will terminate upon notice to the Trustee upon the earliest of
(i) the Distribution Date on which the Certificate Principal Balances of the
Regular Certificates have been reduced to zero, (ii) the final payment or other
liquidation of the last Mortgage Loan in the Trust, (iii) the Distribution Date
in November 2030.

         Capitalized terms used herein that are defined in the Agreement shall
have the meanings ascribed to them in the Agreement, and nothing herein shall be
deemed inconsistent with that meaning.

                  Agreement contains restrictions regarding the transfer of the

<PAGE>



                           2. The Purchaser is acquiring the Certificates for
                  its own account for investment only and not with a view to or
                  for sale in connection with any distribution thereof in any
                  manner that would violate the Act or any applicable state
                  securities laws.

                           3. The Purchaser is (a) a substantial, sophisticated
                  institutional investor having such knowledge and experience in
                  financial and business matters, and, in particular, in such
                  matters related to securities similar to the Certificates,
                  such that it is capable of evaluating the merits and risks of
                  investment in the Certificates, (b) able to bear the economic
                  risks of such an investment and (c) an "accredited investor"
                  within the meaning of Rule 501(a) promulgated pursuant to the
                  Act.

                           4. The Purchaser has been furnished with, and has had
                  an opportunity to review (a) [a copy of the Private Placement
                  Memorandum, dated November [__], 2000, relating to the
                  Certificates (b)] a copy of the Pooling and Servicing
                  Agreement and [(b)] [(c)] such other information concerning
                  the Certificates, the Mortgage Loans and the Company as has
                  been requested by the Purchaser from the Company or the Seller
                  and is relevant to the Purchaser's decision to purchase the
                  Certificates. The Purchaser has had any questions arising from
                  such review answered by the Company or the Seller to the
                  satisfaction of the Purchaser. [If the Purchaser did not
                  purchase the Certificates from the Seller in connection with
                  the initial distribution of the Certificates and was provided
                  with a copy of the Private Placement Memorandum (the
                  "Memorandum") relating to the original sale (the "Original
                  Sale") of the Certificates by the Company, the Purchaser
                  acknowledges that such Memorandum was provided to it by the
                  Seller, that the Memorandum was prepared by the Company solely
                  for use in connection with the Original Sale and the Company
                  did not participate in or facilitate in any way the purchase
                  of the Certificates by the Purchaser from the Seller, and the
                  Purchaser agrees that it will look solely to the Seller and
                  not to the Company with respect to any damage, liability,
                  claim or expense arising out of, resulting from or in
                  connection with (a) error or omission, or alleged error or
                  omission, contained in the Memorandum, or (b) any information,
                  development or event arising after the date of the
                  Memorandum.]

                           5. The Purchaser has not and will not nor has it
                  authorized or will it authorize any person to (a) offer,
                  pledge, sell, dispose of or otherwise transfer any
                  Certificate, any interest in any Certificate or any other
                  similar security to any person in any manner, (b) solicit any
                  offer to buy or to accept a pledge, disposition of other
                  transfer of any Certificate, any interest in any Certificate
                  or any other similar security from any person in any manner,
                  (c) otherwise approach or negotiate with respect to any
                  Certificate, any interest in any Certificate or any other
                  similar security with any person in any manner, (d) make any
                  general solicitation by means of general advertising or in any
                  other manner or (e) take any other action, that (as to any of
                  (a) through (e) above) would constitute a distribution of any
                  Certificate under the Act,


                                      G-1-2

                  that would render the disposition of any Certificate a
                  violation of Section 5 of the Act or any state securities law,
                  or that would require registration or qualification pursuant
                  thereto. The Purchaser will not sell or otherwise transfer any
                  of the Certificates, except in compliance with the provisions
                  of the Pooling and Servicing Agreement.

                        Series 2000-4, Class ___, No. ___


                  The undersigned seller, as registered holder (the
"Transferor"), intends to transfer the Rule 144A Securities described above to
the undersigned buyer (the "Buyer").

                  1. In connection with such transfer and in accordance with the
agreements pursuant to which the Rule 144A Securities were issued, the
Transferor hereby certifies the following facts: Neither the Transferor nor
anyone acting on its behalf has offered, transferred, pledged, sold or otherwise
disposed of the Rule 144A Securities, any interest in the Rule 144A Securities
or any other similar security to, or solicited any offer to buy or accept a
transfer, pledge or other disposition of the Rule 144A Securities, or otherwise
approached or negotiated with respect to the Rule 144A Securities, any interest
in the Rule 144A Securities or any other similar security with, any person in
any manner, or made any general solicitation by means of general advertising or
in any other manner, or taken any other action, which would constitute a
distribution of the Rule 144A Securities under the Securities Act of 1933, as
amended (the "1933 Act"), or which would render the disposition of the Rule 144A
Securities a violation of Section 5 of the 1933 Act or require registration
pursuant thereto, and that the Transferor has not offered the Rule 144A
Securities to any person other than the Buyer or another "qualified
institutional buyer" as defined in Rule 144A under the 1933 Act.

                  2. The Buyer warrants and represents to, and covenants with,

         Securities have not been registered under the 1933 Act or the
         securities laws of any state.

                           b. The Buyer considers itself a substantial,
         sophisticated institutional investor having such knowledge and
         experience in financial and business matters that it is capable of
         evaluating the merits and risks of investment in the Rule 144A

         Rule 144A Securities under the 1933 Act or that would render the
         disposition of the Rule 144A Securities a violation of Section 5 of the
         1933 Act or require registration pursuant thereto, nor will it act, nor
         has it authorized or will it authorize any person to act, in such

         either of the forms of certification to that effect attached hereto as
         Annex 1 or Annex 2. The Buyer is aware that the sale to it is being
         made in reliance on Rule 144A. The Buyer is acquiring the Rule 144A
         Securities for its own account or the account of other qualified
         institutional buyers, understands that such Rule 144A Securities may be
         resold, pledged or transferred only (i) to a person reasonably believed
         to be a qualified institutional buyer that purchases for its own
         account or for the account of a qualified institutional buyer to whom
         notice is given that the resale, pledge or transfer is being made in
         reliance on Rule 144A, or (ii) pursuant to another exemption from
         registration under the 1933 Act.

                  3. The Buyer warrants and represents to, and covenants with,
the Transferor, the Servicer and the Company that either (1) the Buyer is not an
employee benefit plan within the meaning of Section 3(3) of the Employee
Retirement Income Security Act of 1974, as amended ("ERISA") ("Plan"), or a plan
within the meaning of Section 4975(e)(1) of the Internal Revenue Code of 1986
(the "Code") (also a "Plan"), and the Buyer is not directly or indirectly
purchasing the Rule 144A Securities on behalf of, as investment manager of, as
named fiduciary of, as trustee of, or with assets of a Plan, or (2) the Buyer's
purchase of the Rule 144A Securities will not result in a prohibited transaction
under Section 406 of ERISA or Section 4975 of the Code.

                  4. This document may be executed in one or more counterparts
and by the different parties hereto on separate counterparts, each of which,
when so executed, shall be deemed to be an original; such counterparts,

conclude that such third party independently meets the definition of "qualified
institutional buyer" set forth in Rule 144A.

             7. The Buyer will notify each of the parties to which this
certification is made of any changes in the information and conclusions herein.

                  Series 2000-4, Class __

Ladies and Gentlemen:

             This letter is delivered to you in connection with the sale by
___________________________ (the "Seller") to _____________________________ (the
"Purchaser") of a ___% Percentage Interest in the Mortgage Pass-Through
Certificates, Series
2000-4, Class R-I and Class R-II (the "Certificates"), issued pursuant to
Section 5.02 of the Pooling and Servicing Agreement (the "Pooling and Servicing
Agreement"), dated as of November 1, 2000, among Impac Secured Assets Corp., as
company (the "Company"), Impac Funding Corporation, as master servicer and
Bankers Trust Company of California, N.A., as trustee (the "Trustee"). All terms
used herein and not otherwise defined shall have the meaning set forth in the
Pooling and Servicing Agreement. The Seller hereby certifies, represents and
warrants to, and covenants with, the Company and the Trustee that:

             1. No purpose of the Seller relating to the sale of the
Certificates by the Seller to the Purchaser is or will be to impede the
assessment or collection of any tax.

             2. The Seller understands that the Purchaser has delivered to the
Trustee and the Master Servicer a transfer affidavit and agreement in the form
attached to the Pooling and Servicing Agreement as Exhibit G-5. The Seller does
not know or believe that any representation contained therein is false.

             3. The Seller has at the time of the transfer conducted a
reasonable investigation of the financial condition of the Purchaser as
contemplated by Treasury Regulations Section 1.860E-



                                     G-4-1

<PAGE>


1(c)(4)(i) and, as a result of that investigation, the Seller has determined
that the Purchaser has historically paid its debts as they have become due and
has found no significant evidence to indicate that the Purchaser will not
continue to pay its debts as they become due in the future. The Seller
understands that the transfer of the Certificates may not be respected for
United States income tax purposes (and the Seller may continue to be liable for
United States income taxes associated therewith) unless the Seller has conducted
such an investigation.

             4. The Seller has no actual knowledge that the proposed Transferee
is a Disqualified Organization, an agent of a Disqualified Organization or a
Non-United States Person.

                                            Very truly yours,

Servicing Agreement (the "Pooling and Servicing Agreement") dated as of November

as master servicer (the "Master Servicer"), and Bankers Trust Company of

             2. That the Owner (i) is not and will not be a "disqualified
organization" as of _______________[date of transfer] within the meaning of
Section 860E(e)(5) of the Internal Revenue Code of 1986, as amended (the
"Code"), (ii) will endeavor to remain other than a disqualified organization for
so long as it retains its ownership interest in the Class R Certificates, and
(iii) is acquiring the Class R Certificates for its own account or for the
account of another Owner from which it has received an affidavit and agreement
in substantially the same form as this affidavit and agreement. (For this
purpose, a "disqualified organization" means the United States, any state or
political subdivision thereof, any agency or instrumentality of any of the
foregoing (other than an instrumentality all of the activities of which are
subject to tax and, except for Freddie Mac, a majority of whose board of
directors is not selected by any such governmental entity) or any foreign
government, international organization or any agency or instrumentality of such
foreign government or organization, any rural electric or telephone cooperative,
or any organization (other than certain farmers' cooperatives) that is generally
exempt from federal income tax unless such organization is subject to the tax on
unrelated business taxable income).

             3. That the Owner is aware (i) of the tax that would be imposed on
transfers of Class R Certificates to disqualified organizations under the Code,
that applies to all transfers of Class R Certificates after March 31, 1988; (ii)
that such tax would be on the transferor, or, if such transfer is through an
agent (which person includes a broker, nominee or middleman) for a disqualified
organization, on the agent; (iii) that the person otherwise liable for the tax
shall be relieved of liability for the tax if the transferee furnishes to such
person an affidavit that the transferee is not a


                                      G-5-1

<PAGE>



disqualified organization and, at the time of transfer, such person does not
have actual knowledge that the affidavit is false; and (iv) that the Class R
Certificates may be "noneconomic residual interests" within the meaning of
Treasury regulations promulgated pursuant to the Code and that the transferor of
a noneconomic residual interest will remain liable for any taxes due with
respect to the income on such residual interest, unless no significant purpose
of the transfer was to impede the assessment or collection of tax.

             4. That the Owner is aware of the tax imposed on a "pass-through
entity" holding Class R Certificates if at any time during the taxable year of
the pass-through entity a disqualified organization is the record holder of an
interest in such entity. (For this purpose, a "pass through entity" includes a
regulated investment company, a real estate investment trust or common trust
fund, a partnership, trust or estate, and certain cooperatives.)

             5. That the Owner is aware that the Trustee will not register the
transfer of any Class R Certificates unless the transferee, or the transferee's
agent, delivers to it an affidavit and agreement, among other things, in
substantially the same form as this affidavit and agreement. The Owner expressly
agrees that it will not consummate any such transfer if it knows or believes
that any of the representations contained in such affidavit and agreement are
false.

             6. That the Owner has reviewed the restrictions set forth on the
face of the Class R Certificates and the provisions of Section 5.02(f) of the
Pooling and Servicing Agreement under which the Class R Certificates were issued
(in particular, clause (iii)(A) and (iii)(B) of Section 5.02(f) which authorize
the Trustee to deliver payments to a person other than the Owner and negotiate a
mandatory sale by the Trustee in the event the Owner holds such Certificates in
violation of Section 5.02(f)). The Owner expressly agrees to be bound by and to
comply with such restrictions and provisions.

             7. That the Owner consents to any additional restrictions or
arrangements that shall be deemed necessary upon advice of counsel to constitute
a reasonable arrangement to ensure that the Class R Certificates will only be
owned, directly or indirectly, by an Owner that is not a disqualified
organization.

             8.   The Owner's Taxpayer Identification Number is ______________.

             9. This affidavit and agreement relates only to the Class R
Certificates held by the Owner and not to any other holder of the Class R
Certificates. The Owner understands that the liabilities described herein relate
only to the Class R Certificates.

             10. That no purpose of the Owner relating to the transfer of any of
the Class R Certificates by the Owner is or will be to impede the assessment or
collection of any tax.

             11.  That the Owner has no present knowledge or expectation that it
will be unable to pay any United States taxes owed by it so long as any of the
Certificates remain outstanding. In this


                                      G-5-2

<PAGE>



regard, the Owner hereby represents to and for the benefit of the person from
whom it acquired the Class R Certificate that the Owner intends to pay taxes
associated with holding such Class R Certificate as they become due, fully
understanding that it may incur tax liabilities in excess of any cash flows
generated by the Class R Certificate.

             12. That the Owner has no present knowledge or expectation that it
will become insolvent or subject to a bankruptcy proceeding for so long as any
of the Class R Certificates remain outstanding.

             13. The Owner is a citizen or resident of the United States, a
corporation, partnership or other entity created or organized in, or under the
laws of, the United States or any political subdivision thereof, provided that
with respect to any partnership or other entity treated as a partnership for
United States federal income tax purposes, all persons that own an interest in
such partnership either directly or through any entity that is not a corporation
for United States federal income tax purposes are required by the applicable
operative agreement to be United States Persons, or an estate or trust whose
income from sources without the United States is includible in gross income for
United States federal income tax purposes regardless of its connection with the
conduct of a trade or business within the United States.

             14. (a) The Certificates (i) are not being acquired by, and will
not be transferred to, any employee benefit plan within the meaning of section
3(3) of the Employee Retirement Income Security Act of 1974, as amended
("ERISA") or other retirement arrangement, including individual retirement
accounts and annuities, Keogh plans and bank collective investment funds and
insurance company general or separate accounts in which such plans, accounts or
arrangements are invested, that is subject to Section 406 of ERISA or Section
4975 of the Internal Revenue Code of 1986 (the "Code") (any of the foregoing, a
"Plan"), (ii) are not being acquired with "plan assets" of a Plan within the
meaning of the Department of Labor ("DOL") regulation, 29 C.F.R. ss. 2510.3-101
or otherwise under ERISA, and (iii) will not be transferred to any entity that
is deemed to be investing in plan assets within the meaning of the DOL
regulation, 29 C.F.R. ss. 2510.3-101 or otherwise under ERISA; or

             (b) The Owner will provide the Trustee, the Company and the Master
Servicer with an opinion of counsel acceptable to and in form and substance
satisfactory to the Trustee, the Company and the Master Servicer to the effect
that the purchase of Certificates is permissible under applicable law, will not
constitute or result in any non-exempt prohibited transaction under ERISA or
Section 4975 of the Code and will not subject the Trustee, the Company or the
Master Servicer to any obligation or liability (including obligations or
liabilities under ERISA or Section 4975 of the Code) in addition to those
undertaken in the Pooling and Servicing Agreement.

             In addition, the Owner hereby certifies, represents and warrants
to, and covenants with, the Company, the Trustee and the Master Servicer that
the Owner will not transfer such Certificates to any Plan or person unless
either such Plan or person meets the requirements set forth in either (a) or (b)
above.

                      SELLER REPRESENTATIONS AND WARRANTIES

Seller's Representations Assigned by Company to Trustee

             Representations and Warranties. Pursuant to the Mortgage Loan
Purchase Agreement, the Seller has made certain representations and warranties
to the Company. The Seller shall confirm such representations and warranties and
shall deliver a Seller's Warranty Certificate and an Officers' Certificate on
the Closing Date (i) reaffirming such representations and warranties and (ii)
specifically restating and reaffirming the following representations and
warranties as of such date. The following representations are, pursuant to the
Pooling and Servicing Agreement, assigned by the Company to the Trustee for the
benefit of the Certificateholders, together with the related repurchase rights
specified in the Mortgage Loan Purchase Agreement. Pursuant to the Mortgage Loan
Purchase Agreement, the Seller's Warranty Certificate and related Officer's
Certificate, the Seller affirms each such representation and warranty and
agrees, consents to and acknowledges the assignment thereof to the Trustee. All
capitalized terms herein shall have the meanings assigned in the Pooling and
Servicing Agreement and the Seller's Warranty Certificate, as applicable.

             The Seller hereby represents and warrants to the Company and
Trustee, as to each Mortgage Loan, that as of the Closing Date or as of such
other date specifically provided herein:

                (i)        the information set forth in the Mortgage Loan
             Schedule hereto is true and correct in all material respects;

               (ii) the terms of the Mortgage Note and the Mortgage have not

             by written instruments, (i) if required by law in the jurisdiction
             where the Mortgaged Property is located, or (ii) to protect the
             interests of the Trustee on behalf of the Certificateholders;

              (iii) the Mortgage File for each Mortgage Loan contains a true and
             complete copy of each of the documents contained in such Mortgage

             waivers and assumptions that have been executed in connection with
             such Mortgage Loan;

               (iv) immediately prior to the transfer to the Purchaser, the
             Seller was the sole owner of beneficial title and holder of each
             Mortgage and Mortgage Note relating to the Mortgage Loans and is
             conveying the same free and clear of any and all liens, claims,
             encumbrances, participation interests, equities, pledges, charges
             or security interests of any nature and the Seller has full right
             and authority to sell or assign the same pursuant to this
             Agreement;



                                       I-1

<PAGE>



                (v) each Mortgage is a valid and enforceable first lien on the
             property securing the related Mortgage Note and each Mortgaged
             Property is owned by the Mortgagor in fee simple (except with
             respect to common areas in the case of condominiums, PUDs and de
             minimis PUDs) or by leasehold for a term longer than the term of
             the related Mortgage, subject only to (i) the lien of current real
             property taxes and assessments, (ii) covenants, conditions and
             restrictions, rights of way, easements and other matters of public
             record as of the date of recording of such Mortgage, such
             exceptions being acceptable to mortgage lending institutions
             generally or specifically reflected in the appraisal obtained in
             connection with the origination of the related Mortgage Loan or
             referred to in the lender's title insurance policy delivered to the
             originator of the related Mortgage Loan and (iii) other matters to
             which like properties are commonly subject which do not materially
             interfere with the benefits of the security intended to be provided
             by such Mortgage;

               (vi) no payment of principal of or interest on or in respect of
             any Mortgage Loan is 30 or more days past due;

              (vii) there is no mechanics' lien or claim for work, labor or
             material affecting the premises subject to any Mortgage which is or

             except those which are insured against by the title insurance
             policy referred to in (xii) below;

             (viii) as of the Cut-off Date, (i) no Mortgage Loan had been 30
             days or more delinquent more than once during the preceding 12
             months, (ii) no Mortgage Loan had been delinquent for 60 days or
             more during the preceding 12 months and (iii) to Seller's
             knowledge, there was no delinquent tax or assessment lien against
             the property subject to any Mortgage, except where such lien was
             being contested in good faith and a stay had been granted against
             levying on the property;

               (ix) there is no valid offset, defense or counterclaim to any
             Mortgage Note or Mortgage, including the obligation of the
             Mortgagor to pay the unpaid principal and interest on such Mortgage
             Note;

                (x) to Seller's knowledge, except to the extent insurance is in
             place which will cover such damage, the physical property subject
             to any Mortgage is free of material damage and is in good repair
             and there is no proceeding pending or threatened for the total or
             partial condemnation of any Mortgaged Property;

               (xi) to the best of Seller's knowledge, each Mortgage Loan at the
             time it was made complied in all material respects with applicable
             state and federal laws, including, without limitation, usury, equal
             credit opportunity and disclosure laws; and each Mortgage Loan is
             being serviced in all material respects in accordance with
             applicable


                                       I-2

             state and federal laws, including, without limitation, usury,
             equal credit opportunity and disclosure laws;

              (xii) a lender's title insurance policy (on an ALTA or CLTA form)
             or binder, or other assurance of title customary in the relevant
             jurisdiction therefor in a form acceptable to Fannie Mae or Freddie
             Mac, was issued on the date that each Mortgage Loan was created by
             a title insurance company which, to the best of Seller's knowledge,
             was qualified to do business in the jurisdiction where the related
             Mortgaged Property is located, insuring the Seller and its
             successors and assigns that the Mortgage is a first priority lien
             on the related Mortgaged Property in the original principal amount
             of the Mortgage Loan. Seller is the sole insured under such
             lender's title insurance policy, and such policy, binder or
             assurance is valid and remains in full force and effect, and each
             such policy, binder or assurance shall contain all applicable
             endorsements including a negative amortization endorsement, if
             applicable;

             (xiii) in the event the Mortgage constitutes a deed of trust,
             either a trustee, duly qualified under applicable law to serve as
             such, has been properly designated and currently so serves and is
             named in the Mortgage or if no duly qualified trustee has been
             properly designated and so serves, the Mortgage contains
             satisfactory provisions for the appointment of such trustee by the
             holder of the Mortgage at no cost or expense to such holder, and no
             fees or expenses are or will become payable by Purchaser to the
             trustee under the deed of trust, except in connection with a
             trustee's sale after default by the mortgagor;

              (xiv) (i) the Loan-to-Value Ratio of each Mortgage Loan at
             origination was not more than 97.00%; (ii) except with respect to
             approximately 0.44% of the Mortgage Loans (by aggregate outstanding
             principal balance as of the Cut-off Date), each Mortgage Loan with
             a Loan-to-Value Ratio at origination in excess of 80.00% will be
             insured by one of the following: (i) a Primary Insurance Policy
             issued by a private mortgage insurer, (ii) the Radian PMI Pool
             Policy or (iii) a Radian Lender-Paid PMI Policy. Each Primary
             Insurance Policy will insure against default under each insured
             Mortgage Note as follows: (i) for which the outstanding principal
             balance at origination of such Mortgage Loan is greater than or
             equal to 80.01% and up to and including 90.00% of the lesser of the
             Appraised Value and the sales price, such Mortgage Loan is covered
             by a Primary Insurance Policy in an amount equal to at least 20.00%
             of the Allowable Claim and (ii) for which the outstanding principal
             balance at origination of such Mortgage Loan exceeded 90.00% of the
             lesser of the Appraised Value and the sales price, such Mortgage
             Loan is covered by a Primary Insurance Policy in an amount equal to
             at least 25.00% of the Allowable Claim. The Radian PMI Pool Policy
             will insure against default under each insured Mortgage Note
             related to a covered Mortgage Loan originated pursuant to the
             Seller's "Progressive Express(TM)" program as follows: (A) for
             which the outstanding principal balance at origination of such
             Mortgage Loan is at least 80.01% and up to and including 89.99% of
             the lesser of the Appraised Value and the sales price, such
             Mortgage


                                       I-3

<PAGE>



             Loan is covered by such Radian PMI Pool Policy in an amount equal
             to at least 22.00% of the Allowable Claim and (B) for which the
             outstanding principal balance at origination of such Mortgage Loan
             is at least 90.00% and up to and including 95.00% of the lesser of
             the Appraised Value and the sales price, such Mortgage Loan is
             covered by such Radian PMI Pool Policy in an amount equal to at
             least 30.00% of the Allowable Claim. Each Radian Lender-Paid PMI
             Policy will insure against default under each insured Mortgage Note
             related to a covered Mortgage Loan as follows: (A) for which the
             outstanding principal balance at origination of such Mortgage Loan
             is at least 80.01% and up to and including 89.99% of the lesser of
             the Appraised Value and the sales price, such Mortgage Loan is
             covered by such Radian Lender-Paid PMI Policy in an amount equal to
             at least 22.00% of the Allowable Claim, (B) for which the
             outstanding principal balance at origination of such Mortgage Loan
             is at least 90.00% and up to and including 95.00% of the lesser of
             the Appraised Value and the sales price, such Mortgage Loan is
             covered by such Radian Lender-Paid PMI Policy in an amount equal to
             at least 30.00% of the Allowable Claim and (C) for which the
             outstanding principal balance at origination of such Mortgage Loan
             is at least 95.01% and up to and including 97.00% of the lesser of
             the Appraised Value and the sales price, such Mortgage Loan is
             covered by such Radian Lender-Paid PMI Policy in an amount equal to
             at least 35.00% of the Allowable Claim. The "Appraised Value" is
             the appraised value of the related Mortgaged Property at the time
             of origination of such Mortgage Loan. The "Allowable Claim" for any
             Mortgage Loan covered by a Primary Insurance Policy or a Radian PMI
             Pool Policy is the current principal balance of such Mortgage Loan
             plus accrued interest and allowable expenses at the time of the
             claim;
