                  This Pooling and Servicing Agreement, dated and effective as
of September 1, 1999, among Impac Secured Assets Corp., as depositor (the
"Depositor"), Impac Funding Corporation, as master servicer (the "Master
Servicer"), and Bankers Trust Company of California, N.A., as trustee (the
"Trustee").

                             PRELIMINARY STATEMENT:

                  The Depositor intends to sell mortgage 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 Mortgage Loans (as defined herein).

                                     REMIC I
                                     -------

           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 I." The Class R-I Certificates will
represent the sole class of "residual interests" in REMIC I for purposes of the
REMIC Provisions (as defined herein) under federal income tax law. The following
table irrevocably sets forth the designation, the remittance rate (the "REMIC I
Remittance Rate"), the initial Uncertificated Balance, and solely for purposes
of satisfying Treasury regulation Section 1.860G-1(a)(4)(iii), the "latest
possible maturity date" for each of the REMIC I Regular Interests. None of the
REMIC I Regular Interests will be certificated.

           Section 1.02.  Determination of LIBOR

           LIBOR for the Accrual Period for the Distribution Date in October
1999 will be 5.38% per annum. LIBOR applicable to the calculation of the
Pass-Through Rate on the Class A Certificates for any other Accrual Period will
be determined on each LIBOR Rate Adjustment Date.

           On each LIBOR Rate Adjustment Date, LIBOR shall be established by the
Trustee and, as to any Accrual Period, will equal the rate for one month United
States dollar deposits that appears on the Telerate Screen Page 3750 as of 11:00
a.m., London time, on such LIBOR Rate Adjustment Date. "Telerate Screen Page
3750" means the display designated as page 3750 on the Telerate Service (or such
other page as may replace page 3750 on that service for the purpose of
displaying London interbank offered rates of major banks). If such rate does not
appear on such page (or such other page as may replace that page on that
service, or if such service is no longer offered, LIBOR shall be so established
by use of such other service for displaying LIBOR or comparable rates as may be
selected by the Trustee after consultation with the Master Servicer and the
Insurer), the rate will be the Reference Bank Rate. The "Reference Bank Rate"
will be determined on the basis of the rates at which deposits in U.S. Dollars
are offered by the reference banks (which shall be any three major banks that
are engaged in transactions in the London interbank market, selected by the
Trustee after consultation with the Master Servicer and the Insurer) as of 11:00
a.m., London time, on the LIBOR Rate Adjustment Date to prime banks in the
London interbank market for a period of one month in amounts approximately equal
to the Certificate Principal Balance of the Class A Certificates then
outstanding. The Trustee will request the principal London office of each of the
reference banks to provide a quotation of its rate. If at least two such
quotations are provided, the rate will be the arithmetic mean of the quotations
rounded up to the next multiple of 1/16%. If on such date fewer than two
quotations are provided as requested, the rate will be the arithmetic mean of
the rates quoted by one or more major banks in New York City, selected by the
Trustee after consultation with the Master Servicer and the Insurer, as of 11:00
a.m., New York City time, on such date for loans in U.S. Dollars to leading
European banks for a period of one month in amounts approximately equal to the
aggregate Certificate Principal Balance of the Class A Certificates then
outstanding. If no such quotations can be obtained, the rate will be LIBOR for
the prior Distribution Date; provided however, if, under the priorities
described above, LIBOR for a Distribution Date would be based on LIBOR for the
previous Distribution Date for the third consecutive Distribution Date, the
Trustee, after consultation with the Insurer, shall select an alternative
comparable index (over which the Trustee has no control), used for determining
one-month Eurodollar lending rates that is calculated and published (or
otherwise made available) by an independent party.

           The establishment of LIBOR by the Trustee on any LIBOR Rate
Adjustment Date and the Trustee's subsequent calculation of the Pass-Through
Rate applicable to the Class A Certificates for the relevant Accrual Period, in
the absence of manifest error, will be final and binding.

           Promptly following each LIBOR Rate Adjustment Date the Trustee shall
supply the Master

                                      -37-


Servicer and the Insurer with the results of its determination of LIBOR on such
date. Furthermore, the Trustee will supply to any Certificateholder so
requesting by telephone the Pass-Through Rate on the Class A Certificates for
the current and the immediately preceding Accrual Period.

                                   ARTICLE II

                          CONVEYANCE OF MORTGAGE LOANS;
                        ORIGINAL ISSUANCE OF CERTIFICATES

           SECTION 2.01.Conveyance of Mortgage Loans.

           The Depositor, 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 Depositor 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 and the Insurer. 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) and the Yield Maintenance Agreement
Purchase Price.

           In connection with such transfer and assignment, the Depositor 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 "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 1999-1" with all intervening endorsements showing a complete 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 applicable public recording office, a copy of
     the Mortgage certified by the Seller 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 Trust Company of California, N.A., as trustee
     for holders of Impac Secured Assets Corp., Mortgage Pass-Through
     Certificates", Series 1999-1;

           (iv) the original recorded Assignment or Assignments of the Mortgage
     showing a complete 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;



<PAGE>


                                      -39-


            (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) the original of any assumption, modification, extension or
     guaranty agreement; and

           (vii) the original or a copy of the private mortgage insurance policy
     or original certificate of private mortgage insurance for each Mortgage
     Loan, if applicable.

           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 a complete 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.
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 and the
Insurer.

           Except as may otherwise expressly be provided herein, neither the
Depositor, the Master Servicer nor the Trustee shall (and the Master Servicer
shall ensure that no Sub-Servicer shall)

                                      -40-


assign, sell, dispose of or transfer any interest in the Trust Fund or any
portion thereof, or permit the Trust Fund or any portion thereof to be subject
to any lien, claim, mortgage, security interest, pledge
or other encumbrance of, any other Person.

           It is intended that the conveyance of the Mortgage Loans by the
Depositor to the Trustee as provided in this Section be, and be construed as, a
sale of the Mortgage Loans as provided for in this Section 2.01 by the Depositor
to the Trustee for the benefit of the Certificateholders and the Insurer. It is,
further, not intended that such conveyance be deemed a pledge of the Mortgage
Loans by the Depositor to the Trustee to secure a debt or other obligation of
the Depositor. However, in the event that the Mortgage Loans are held to be
property of the Depositor, or if for any reason this Agreement is held or deemed
to create a security interest in the Mortgage Loans, 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 Depositor
to the Trustee of a security interest in all of the Depositor's right (including
the power to convey title thereto), title and interest, whether now owned or
hereafter acquired, in and to (A)(1)the Mortgage Loans, including the Mortgage
Notes, the Mortgages, any related Insurance Policies and all other documents in
the related Mortgage Files and (2) the Yield Maintenance Agreement Purchase
Price, (B) all amounts payable to the holders of the Mortgage Loans in
accordance with the terms thereof, and (C) all proceeds of the conversion,
voluntary or involuntary, of the foregoing into cash, instruments, securities or
other property, including without limitation all 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 Depositor 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 (C); (c) the possession by the
Trustee or its agent 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 Depositor 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, 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 and the Insurer.

           The Trustee agrees, for the benefit of the Certificateholders and the
Insurer, 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 Depositor, the Insurer
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
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
Depositor, the Insurer 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, the Insurer and the Depositor. 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 and the Insurer that the Seller
purchase such



<PAGE>


                                      -42-


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 Depositor.

           (a) The Master Servicer hereby represents and warrants to and
covenants with the Depositor, the Insurer 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 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;




<PAGE>


                                      -43-


                       (iv) This Agreement, assuming due authorization,
         execution and delivery by the Depositor 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 or, to the best of the
         Master Servicer's knowledge, threatened against the Master Servicer
         which would prohibit its entering into this Agreement or performing its
         obligations under this Agreement 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 or federal court, agency,
         regulatory authority or other governmental body having jurisdiction
         over the Master Servicer, other than such as have been obtained; and

                       (ix) As of the date hereof, no information, certificate
         of an officer, statement furnished in writing or report delivered to
         the Depositor, any affiliate of the Depositor or the Trustee by the
         Master Servicer in its capacity as Master Servicer, to the knowledge of
         the Master Servicer, contains any untrue statement of a material fact.

                  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
Depositor, the Trustee, the Insurer and the Certificateholders. Upon discovery
by the Depositor, the Trustee, the Insurer 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



<PAGE>


                                      -44-


Insurer, Depositor or the Trustee, the party discovering such breach shall give
prompt written notice to the other parties.

                  (b) The Depositor hereby represents and warrants to the Master
Servicer, the Insurer 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 Depositor, the Master Servicer,
the Insurer 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 Insurer or 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 Depositor hereby assigns to the Insurer and the Trustee
for the benefit of Certificateholders its interest in respect of the
representations and warranties made by the Seller in the Mortgage Loan Purchase
Agreement or the exhibits thereto. 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 and the Insurer. Upon the discovery by the Depositor, the
Master Servicer, the Insurer 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 Insurer or Certificate holders in such Mortgage Loan, the party
discovering such breach shall give prompt written notice to the other parties
(including the Insurer). 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 Depositor 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.



<PAGE>


                                      -45-


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 Seller shall deliver to the Trustee for the benefit of the
Certificateholders 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 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
Depositor shall amend or cause to be amended the Mortgage Loan Schedule for the
benefit of the Certificateholders and the Insurer to reflect the removal of such
Deleted Mortgage Loan and the substitution of the Qualified Substitute Mortgage
Loan or Loans and the Depositor 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 date of substitution, and the Depositor 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 Section 2.03 hereof.

                  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 (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 Seller
shall 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. 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 the
REMIC, including without limitation, any federal tax imposed on "prohibited
transactions" under Section 860F(a)(1) of the Code or on "contributions after
the startup date" under Section 860G(d)(1) of the Code or (b) any portion of
REMIC I, REMIC II or REMIC III 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.

                                   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 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. 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 Primary 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 (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 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.

                  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



<PAGE>


                                      -49-


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. No costs
incurred by the Master Servicer or by Sub-Servicers in effecting the payment of
taxes and assessments on the Mortgaged Properties shall, for the purpose of
calculating distributions to Certificateholders, be added to the amount owing
under the related Mortgage Loans, notwithstanding that the terms of such
Mortgage Loans so permit.

                  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 REMIC I, REMIC II or REMIC
III to fail to qualify as REMICs 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. 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
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



<PAGE>


                                      -50-


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 Funding, Inc.

         The Master Servicer has entered into Sub-servicing Agreements with the
initial Sub-Servicer 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, the Insurer 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.

                  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 accor dance with the terms and
conditions of such Sub-Servicing Agreement. In the event of termination of any
Sub-Servicer, all servicing obligations of such Sub-Servicer shall be assumed
simultaneously by the 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



<PAGE>


                                      -51-


all circumstances remain obligated and primarily liable to the Trustee, the
Insurer 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 Agree ment, 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, the Insurer 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 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) 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



<PAGE>


                                      -52-


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.

                  (c) Unless an Insurer Default exists, the Master Servicer
will, if it is authorized to do so under the relevant Subservicing Agreement,
upon request of the Insurer at a time when the Insurer may remove the Master
Servicer under the terms hereof, terminate any Sub-servicing
Agreement.

                  SECTION 3.07. Collection of Certain Mortgage Loan Payments.

                  (a) The Master Servicer will coordinate and monitor
remittances by Sub- Servicers to the Trustee 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.




<PAGE>


                                      -53-


                  (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 Servicer shall provide to the
Trustee a certificate of a Servicing Officer that such Mortgage Loan became a
Liquidated Mortgage Loan and has 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 and the Insurer. 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-Servicing 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



<PAGE>


                                      -54-


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, payments under the Radian PMI Policy 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 on account of principal, including Principal
         Prepayments, on the Mortgage Loans;

               (ii) all payments on account of interest on the Mortgage Loans,
         net of any portion thereof retained by the Master Servicer as Master
         Servicing Fees or any Sub-Servicer as Servicing Fees and net of any
         portion thereof payable to Radian under the Radian PMI
         Policy;




<PAGE>


                                      -55-


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

               (iv) all proceeds of any Mortgage Loan or REO Property
         repurchased or purchased in accordance with Sections 2.02, 2.04 , 3.14,
         3.22, 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 or 3.13.

                  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 Depositor 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 Depositor, 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 Master Servicing Fees and Servicing Fees) of Monthly
         Payments on Mortgage



<PAGE>


                                      -56-


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

                         (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 for unpaid Master Servicing
         Fees 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); and

                        (ix) 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 (viii).

                  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



<PAGE>


                                      -57-


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.

                  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 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 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%



<PAGE>


                                      -58-


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.

         The Master Servicer shall take all such actions on behalf of the Trust
Fund as are necessary to service, maintain and administer the Radian PMI Policy
and to enforce the Trust Fund's rights under the Radian PMI Policy. The Master
Servicer shall effect the timely payment of the premium on the Radian PMI
Policy. To the extent the Mortgagor with respect to a Radian PMI Insured Loan is
delinquent, the Master Servicer shall advance the related premium as a Servicing
Advance. Except as expressly set forth herein, the Master Servicer shall have
full authority on behalf of the Trust Fund to do anything it reasonably deems
appropriate or desirable in connection with the servicing, maintenance and
administration of the Radian PMI Policy. The Master Servicer shall make its best
reasonable efforts to file all insured claims under the Radian PMI Policy and
collect from Radian all Insurance Proceeds due to the Trust Fund under the
Radian PMI Policy. The Master Servicer shall not take, or permit any subservicer
to take, any action which would result in non- coverage under the Radian PMI
Policy of any loss which, but for the actions of the Master Servicer or any
Subservicer, would have been covered thereunder. To the extent coverage is
available, the Master Servicer shall keep or cause to be kept in full force and
effect each Radian PMI Policy for the life of the Mortgage Loan. Neither the
Master Servicer nor the Trustee shall terminate the Radian PMI Policy with
respect to any Mortgage Loan. 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 PMI Loan.

         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 use its best reasonable efforts to 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



<PAGE>


                                      -59-


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 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. 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 purchase a Mortgage Loan from
the Trust Fund 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 appli cable 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



<PAGE>


                                      -60-


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 REMIC I, REMIC II or REMIC III to fail to qualify as
REMICs 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 re tained by or on behalf of the Master Servicer as additional servicing
compensation. In connection 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 REMIC I, REMIC II or REMIC III to fail to qualify as
REMICs 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 or the Master Servicer
for consenting in any such conveyance or entering into any such assumption
agreement may be retained by the related Sub-Servicer or the Master 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.




<PAGE>


                                      -61-


                  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 other wise 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 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 or the Insurer after reimbursement to itself
for such expenses, and (ii) that such expenses will be re coverable 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, 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 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 Master Servicing Fees and Servicing Fees; and second, to
interest at the Net Mortgage Rate. The portion of the recovery so allocated to
unpaid Master Servicing Fees and 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; 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 cancelled 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 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.




<PAGE>


                                      -63-


                  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 Master Servicing Fees and Servicing Fees with respect to each Mortgage Loan
(less any portion of the Servicing Fees retained by any Sub-Servicer). In
addition, the Master Servicer shall be entitled to recover unpaid Master
Servicing Fees and 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 and the Certificate Account as
additional servicing compensation interest or other income earned on deposits
therein, subject to Section 3.23, as well as any prepayment charges, assumption
fees, late payment charges and reconveyance fees. The Master Servicer shall be
required to pay all expenses incurred by it in connection with its servicing
activities hereunder (including servicing compensation of the Sub-Servicer to
the extent not retained by it and the fees and expenses of the Trustee), and
shall not be entitled to reimbursement therefor except as specifically provided
in Section 3.11. The Master 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 (to the extent generally
commerically available from time to time) at its own expense and for the
duration of this Agreement a blanket fidelity bond and shall cause each
Sub-Servicer to obtain and maintain an errors and omissions insurance policy
covering 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 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

                                      -64-


generally not regarded as excessive by industry standards. The Master Servicer
shall promptly notify the Trustee 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
December 1999, the Master Servicer at its own expense shall deliver to the
Trustee, with a copy to the Rating Agencies and the Insurer, 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 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
December, 1999, 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, the Insurer 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



<PAGE>


                                      -65-


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 1999, 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, the Insurer 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 regarding
the related Mortgage Loans and REO Property 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 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 the Trust Fund and shall not apply to any REO Property relating
to a Mortgage Loan which was purchased or repurchased from the Trust Fund
pursuant to Sections 2.02, 2.04, 3.14 or 3.24. In the event that title



<PAGE>


                                      -66-


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 the Trust Fund, shall either sell any REO
Property before the close of the third taxable year following the taxable year
in which the Trust Fund acquires ownership of such REO Property for purposes of
Section 860G(a)(8) of the Code or, at the expense of the Trust Fund, 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 and the Insurer an Opinion of Counsel,
addressed to the Trustee, the Insurer and the Master Servicer, to the effect
that the holding by the Trust Fund of such REO Property subsequent to three
years after its acquisition will not result in the imposition on The Trust Fund
of taxes on "prohibited transactions" thereof, as defined in Section 860F of the
Code, or cause REMIC I, REMIC II or REMIC III to fail to qualify as REMICs 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 and the Insurer 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 the Trust Fund 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 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 Master Servicing Fees and Servicing Fees from proceeds received in
connection with



<PAGE>


                                      -67-


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 and the Insurer 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 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



<PAGE>


                                      -68-


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 reimburse ment 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 Depositor.

                  The Depositor agrees that on or prior to the tenth day after
the Closing Date, the Depositor 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 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 Balance 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 of such class of Certificates
was sold, or



<PAGE>


                                      -69-


(d) if any Certificates of each Class of Certificates are retained by the
Depositor 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 Depositor
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 Depositor 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 Depositor 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.

                  (C) Notwithstanding the distributions on the REMIC I Regular

              (v) to the Class A Certificateholders in respect of any Unpaid

be paid to the Depository, as Holder thereof, and the Depository shall be
responsible for crediting the amount of such distribution to the accounts of its
Depository Participants in accordance with its normal procedures. Each
Depository Participant shall be responsible for disbursing such distribution to
the Certificate Owners that it represents and to each indirect participating
brokerage firm (a "brokerage firm" or "indirect participating firm") for which
it acts as agent. Each brokerage firm shall be responsible for disbursing funds
to the Certificate Owners that it represents. None of the Trustee, the Depositor
or the Master Servicer shall have any responsibility therefor except as
otherwise provided by this Agreement or applicable law.

           (g) The Trustee shall, upon written direction from the Master
Servicer, invest or cause the institution maintaining the Certificate Account to
invest the funds in the Certificate Account in Permitted Investments designated
in the name of the Trustee for the benefit of the Certificateholders and the
Insurer, which shall mature not later than the Business Day next preceding the
Distribution Date next following the date of such investment (except that (i)
any investment in the institution with which the Certificate Account is
maintained may mature on such Distribution Date and (ii) any other investment
may mature on such Distribution Date if the Trustee shall advance funds on such
Distribution Date to the Certificate Account in the amount payable on such
investment on such Distribution Date, pending receipt thereof to the extent
necessary to make distributions on the Certificates) and shall not be sold or
disposed of prior to maturity. All income and gain realized from any such
investment shall be for the benefit of the Master Servicer and shall be subject
to its withdrawal or order from time to time. The amount of any losses incurred
in respect of any such investments shall be deposited in the Certificate Account
by the Master Servicer out of its own funds immediately as realized without any
right of reimbursement.

           (h) Except as otherwise provided in Section 9.01, if the Master
Servicer anticipates that a final distribution with respect to any Class of
Certificates will be made on the next Distribution Date, the Master Servicer
shall, no later than the Determination Date in the month of such final
distribution, notify the Trustee and the Trustee shall, no later than two (2)
Business Days after such Determination Date, mail on such date to each Holder of
such Class of Certificates a notice to the effect that: (i) the Trustee
anticipates that the final distribution with respect to such Class of
Certificates will be made on such Distribution Date but only upon presentation
and surrender of such Certificates at the office of the Trustee or as otherwise
specified therein, and (ii) no interest shall accrue on such Certificates from
and after the end of the related Accrual Period.

           Any funds not distributed to any Holder or Holders of Certificates of
such Class on such Distribution Date because of the failure of such Holder or
Holders to tender their Certificates shall, on such date, be set 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(h) 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 receive the final distribution with
respect thereto. If within six months after the second notice all such
Certificates shall not have been surrendered for cancellation, the Trustee shall
take reasonable steps as directed by the Depositor, 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

thereof in accordance with this Section 4.01(h).

year, the Trustee shall prepare and forward, to each Person who at any time
during the calendar year was a Holder of a Certificate, a statement containing
the information set forth in subclauses (i) - (iii) above, aggregated for such
calendar year or applicable portion thereof during which such person was a
Certif icateholder. Such obligation of the Trustee shall be deemed to have been
satisfied to the extent that substantially comparable information shall be
provided by the Trustee pursuant to any requirements of the Code and regulations
thereunder as from time to time are in force.

           On each Distribution Date the Trustee shall prepare and forward, to

<PAGE>


                                      -76-


Residual Certificate a statement containing the information provided pursuant to
the previous paragraph aggregated for such calendar year or applicable portion
thereof during which such Person was a Certificateholder. Such obligation of the
Trustee shall be deemed to have been satisfied to the extent that substantially
comparable information shall be provided by the Trustee pursuant to any
requirements of the Code as from time to time are in force.

           SECTION 4.03.  Remittance Reports; Advances by the Master Servicer.

           (a) On the Business Day following each Determination Date, the Master
Servicer shall deliver to the Trustee and the Insurer a report, prepared as of
the close of business on the Determination Date (the "Determination Date
Report"), in the form of an electromagnetic tape or disk. The Determination Date
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. Not later than each Certificate Account
Deposit Date, the Trustee shall furnish by telecopy to the Master Servicer a
statement setting forth (i) the Available Distribution Amount, (ii) the amounts
required to be withdrawn from the Custodial Account and deposited into the
Certificate Account with respect to the immediately succeeding Distribution Date
pursuant to clause (ii) of Section 4.01(a), and (iii) the Certificate Insurer
Premium and, if the Master Servicer determines that a Deficiency Amount exists
for such Distribution Date, the amount necessary to complete the notice in the
form of Exhibit A to the Policy (the "Notice"). The Trustee shall have no
obligation to recompute, recalculate or verify any information provided to it by
the Master Servicer. The determination by the Trustee of such amounts shall, in
the absence of obvious error, be presumptively deemed to be correct for all
purposes hereunder.

           (b) Not later than 2:00 P.M. New York time on each Certificate
Account Deposit Date, the Trustee shall notify the Master Servicer of 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 the aggregate
amount of Monthly Payments (with each interest portion thereof adjusted to the
Mortgage Rate, less the Master Servicing Fee and Servicing Fee, or reductions in
the amount of principal collectable from the Mortgagor pursuant to a Deficient
Valuation), 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; provided that no Advance shall be made if it would be a
Nonrecoverable Advance. 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
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)



<PAGE>


                                      -77-


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, the Insurer and the
Trustee with the Determination Date 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 Trustee
pursuant to paragraph (b) above, it shall give notice to the Trustee and the
Insurer of its inability to Advance (such notice may be given by telecopy), not
later than 4:00 P.M., New York time, on such date, specifying the portion of
such amount that it will be unable to deposit. Not later than 4:00 P.M., New
York time, on the earlier of (x) two Business Days following such Certificate
Account Deposit Date or (y) the Business Day preceding the related Distribution
Date, unless by such time the Master Servicer shall have directly or indirectly
deposited in the Certificate Account the entire amount of the Advances required
to be made for the related Distribution Date, pursuant to Section 7.01, the
Trustee shall (a) terminate all of the rights and obligations of the Master
Servicer under this 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 immediately succeeding Distribution Date.

           SECTION 4.04.  Allocation of Realized Losses.

           Prior to each Distribution Date, the Master Servicer shall determine
the total amount of Realized Losses, if any, that resulted from any Cash
Liquidation, Debt Service Reduction, Deficient Valuation or REO Disposition that
occurred during the related Prepayment Period. The amount of each Realized Loss
shall be evidenced by an Officers' Certificate from the Master Servicer to the
Trustee. All Realized Losses remaining after the allocation of such amounts in
reduction of the funds on deposit in the Reserve Fund shall be allocated by the
Trustee on each Distribution Date to the following REMIC I Regular Interests in
the specified percentages, as follows: first, to Uncertificated Interest payable
to the REMIC I Regular Interest I-LT1 and REMIC I Regular Interest I-LT3 up to
an aggregate amount equal to 1% of the Net Monthly Excess Cash Flow, 98% and 2%,
respectively; second, to the Uncertificated Balances of the REMIC I Regular
Interest I-LT1 and REMIC I Regular Interest I-LT3, until the Uncertificated
Balance of the REMIC I Regular Interest I-LT3 is equal to that of REMIC I
Regular Interest I-LT2, 98% and 2%, respectively; third, to the Uncertificated
Balances of REMIC I Regular Interests I-LT1, I-LT2 and I-LT3, pro rata, until
the Uncertificated Balance of REMIC I Regular Interest I-LT3 has been reduced to
zero.

           All Realized Losses on the REMIC II Regular Interests shall be
allocated by the Trustee on each Distribution Date among the REMIC II Regular
Interests in the proportion that Realized Losses are allocated to the related
Uncertificated Corresponding Component.

           As used herein, an allocation of a Realized Loss on a "pro rata
basis" among two or more specified Classes of Certificates means an allocation
on a pro rata basis, among the various Classes so specified, to each such Class
of Certificates on the basis of their then outstanding Certificate Principal
Balances prior to giving effect to distributions to be made on such Distribution
Date in the case of the principal portion of a Realized Loss or among the
various Classes so specified based on the Accrued Certificate Interest thereon
payable on such Distribution Date (without regard to any Compensating Interest
for such Distribution Date) in the case of an interest portion of a Realized
Loss. Allocations of the interest portions of Realized Losses shall be made by
operation of the definition of "Accrued Certificate Interest" and by operation
of the provisions of Section 4.01. Allocations of the principal portion of Debt
Service Reductions shall be made by operation of the provisions of Section 4.01.
All Realized Losses and all other losses allocated to a Class of Certificates
hereunder will be allocated among the Certificates of such Class in proportion
to the Percentage Interests evidenced thereby.

           SECTION 4.05.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,



<PAGE>


                                      -79-


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 4.06. 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.

           SECTION 4.07. Yield Maintenance Agreement and Reserve Fund.

           (a) On the Closing Date, the Trustee, as trustee for the benefit of
the Insurer and the Certificateholders, shall enter into the Yield Maintenance
Agreement with DLJIC. The initial amount payable by the Trust Fund pursuant to
the Yield Maintenance Agreement shall be paid by Impac Funding on behalf of the
Trust Fund on or prior to the Closing Date in accordance with the Yield
Maintenance Agreement, in an amount equal to the Yield Maintenance Agreement
Purchase Price. Such payment shall be deemed to have been made as of the Closing
Date. Impac Funding shall be a third-party beneficiary of the Yield Maintenance
Agreement and shall have a right to amounts payable by DLJIC pursuant to the
Yield Maintenance Agreement in excess of the Reserve Fund YMA Addition and
certain other related amounts.

           (b) Immediately prior to each Distribution Date, the Trustee shall
deposit into the Reserve Fund the Reserve Fund YMA Addition and the Reserve Fund
Cash Flow Addition. On each Distribution Date, the Trustee shall withdraw from
the Reserve Fund (to the extent of funds available on deposit therein) and
include in Available Funds (to be distributed in the priority of Section
4.01(e)) an amount equal to the sum of (a) Cumulative Insurance Payments (to the
extent such payments would not otherwise be covered by distributions pursuant to
clause (iii) of Section 4.01(e)) and (b) the excess of (x) the amount of
Realized Losses on the Mortgage Loans for such Distribution Date over (y) the
Net Monthly Excess Cash Flow for such Distribution Date.

           (c) If following the distribution of Available Funds on any
Distribution Date pursuant to Section 4.01(e), the Overcollateralization Amount
is equal to or greater than the Required Overcollateralization Amount, any
amounts held in the Reserve Fund shall be paid as follows, with any amounts not
paid as described below to remain in the Reserve Fund:




<PAGE>


                                      -80-


              (i) FIRST, to the holders of the Class A Certificates, any Basis
           Risk Shortfall Carry- Forward Amount; and

              (ii) SECOND, in addition, if the Net WAC Cap Rate exceeds the
           lesser of clauses (i) and (ii) of the definition of Pass-Through Rate
           for the Class A Certificates by at least 0.25% per annum, or if on or
           prior to such Distribution Date the Certificate Principal Balance of
           the Class A Certificates has been reduced to zero, the entire amount
           in the Reserve Fund following distributions pursuant to clause (i)
           shall be paid to the Holders of the Class SB Certificates.

           (d) The Reserve Fund shall be an Eligible Account. Amounts held in
the Reserve Fund from time to time shall continue to constitute assets of the
Trust Fund, but not of the REMIC, until released from the Reserve Fund pursuant
to this Section 4.07. The Yield Maintenance Agreement and the Reserve Fund
constitute an "outside reserve fund" within the meaning of Treasury Regulation
ss.1.860G-2(h) and are not assets of REMIC I, REMIC II or REMIC III. The Holders
of the Class SB Certificates are the owners of the Reserve Fund and the Yield
Maintenance Agreement and for all federal tax purposes, amounts transferred by
REMIC III to the Reserve Fund are treated as amounts first distributed by the
REMIC to the Holders of the Class SB Certificates, and then by the Holders of
the Class SB Certificates to the Reserve Fund. The Trustee shall keep records
that accurately reflect the funds on deposit in the Reserve Fund. The Trustee
shall invest the Reserve Fund in Permitted Investments. On each Distribution
Date, the Trustee shall distribute any investment earnings on the Reserve Fund
to the Holder of the Class SB Certificates.

           SECTION 4.08. The Policy.

           (a) If pursuant to Section 4.03(a), the Master Servicer determines
that a Deficiency Amount exists for such Distribution Date, the Trustee shall
complete the Notice and submit such Notice in accordance with the Policy to the
Insurer no later than 12:00 P.M., New York City time, on the Business Day
immediately preceding each Distribution Date, as a claim for an Insured Amount
(provided that the Trustee shall submit such Notice on the second Business Day
immediately preceding such Distribution Date if it is able to do so) in an
amount equal to such Deficiency Amount.

           (b) The Trustee shall establish and maintain the Insurance Account on
behalf of the Holders of the Class A Certificates. Upon receipt of an Insured
Amount from the Insurer on behalf of the Class A Certificateholders, the Trustee
shall deposit such Insured Amount in the Insurance Account. All amounts on
deposit in the Insurance Account shall remain uninvested. On each Distribution
Date, the Trustee shall transfer any Insured Amount then on deposit in the
Insurance Account to the Certificate Account.




<PAGE>


                                      -81-


           (c) The Trustee shall (i) receive as attorney-in-fact of each Class A
Certificateholder any Insured Amount from the Insurer and (ii) distribute such
Insured Amount to such Class A Certificateholders as set forth in subsection (b)
above.

           (d) The Trustee promptly shall notify the Insurer of any proceeding
or the institution of any action seeking the avoidance as a preferential
transfer under applicable bankruptcy, insolvency, receivership or similar law (a
"Preference Claim") of any distribution made with respect to the Class A
Certificates. Each Holder, by its purchase of Class A Certificates, and the
Trustee hereby agree that the Insurer (so long as no Insurer Default exists) may
at any time during the continuation of any proceeding relating to a Preference
Claim direct all matters relating to such Preference Claim, including, without
limitation, (i) the direction of any appeal of any order relating to any
Preference Claim and (ii) the posting of any surety, supersedeas or performance
bond pending any such appeal. In addition and without limitation of the
foregoing, the Insurer shall be subrogated to the rights of the Trustee and each
such Holder in the conduct of any such Preference Claim, including, without
limitation, all rights of any party to an adversary proceeding action with
respect to any order issued in connection with any such Preference Claim.
Insured Amounts paid by the Insurer to the Trustee shall be received by the
Trustee, as agent to the Certificateholders. The Trustee is not permitted to
make a claim on the Trust or on any Certificateholder for payments made to
Certificateholders under the Policy which are characterized as preference
payments by any federal bankruptcy court having jurisdiction over any bankrupt
Mortgagor unless ordered to do so by such bankruptcy court.

           (e) Insured Amounts disbursed by the Trustee from proceeds of the
Policy shall not be considered payment by the Trust Fund with respect to the
Class A Certificates, nor shall such disbursement of such Insured Amounts
discharge the obligations of the Trust Fund with respect to the amounts thereof,
and the Insurer shall become owner of such amounts to the extent covered by such
Insured Amounts as the deemed assignee of such Class A Certificateholders. The
Trustee hereby agrees on behalf of each Class A Certificateholder (and each
Class A Certificateholder, by its acceptance of its Class A Certificates, hereby
agrees) for the benefit of the Insurer that the Trustee shall recognize that to
the extent the Insurer pays Insured Amounts, either directly or indirectly (as
by paying through the Trustee), to the Class A Certificateholders, the Insurer
will be entitled to be subrogated to the rights of the Class A
Certificateholders to the extent of such payments.

                                THE CERTIFICATES

           SECTION 5.01. The Certificates.

           (a) The Certificates will be substantially in the respective forms
annexed hereto as Exhibits A-1, B-1 and B-2. The Certificates will be issuable
in registered form only. The Class A Certificates shall be issuable in minimum
dollar denominations of $25,000 and integral multiples of $1 in excess thereof.
The Class SB Certificates shall be issuable in registered, certificated form in
minimum Percentage Interests of 5.00% and integral multiples of 0.01% in excess
thereof. Each Class of Class R Certificates will each be issuable in minimum
denominations of any Percentage Interest representing 5.00% and multiples of
0.01% in excess thereof.

           Upon original issue, the Certificates shall, upon the written request
of the Depositor executed by an officer of the Depositor, be executed and
delivered by the Trustee, authenticated by the Trustee and delivered to or upon
the order of the Depositor 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. Cer tificates 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 Certif
icates 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 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 Class A Certificates (except for such remainders) 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 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, the Master Servicer and the Depositor 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 Depositor advises the Trustee in writing that the
Depository is no longer willing or able to properly discharge its
responsibilities as Depository and (B) the Depositor is unable to locate a
qualified successor or (ii) the Depositor 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 Depositor, issue the
Definitive Certificates. Neither the Depositor, 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.

           SECTION 5.02. Registration of Transfer and Exchange of Certificates.

           (a) The Trustee shall maintain a Certificate Register (in such
capacity, the "Certificate Registrar") 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 SB or 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"),



<PAGE>


                                      -84-


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 SB 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 Depositor 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 Depositor or any affiliate thereof, to a
non-affiliate of the Depositor 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 Depositor
and the Trustee the facts surrounding such transfer, which representation
letters shall not be an expense of the Trustee, the Depositor 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 Depositor to an
affiliate of the Depositor 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 Depositor of the status of such transferee as
an affiliate of the Depositor. Any such Certificateholder desiring to effect
such transfer shall, and does hereby agree to, indemnify the Trustee, the
Depositor 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 SB or 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 Depositor 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 Depositor 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 SB or Class R Certificates may be made pursuant to this
Section 5.02(c) by the Depositor. Any such Certificateholder desiring to effect
such transfer shall, and does hereby agree to, indemnify the Trustee, the
Depositor 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.

           (d) The Trustee shall require an Opinion of Counsel from a
prospective transferee prior to the transfer of any Class SB or Residual
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



<PAGE>


                                      -85-


(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 disposition will not violate the
prohibited transaction provisions of Section 406 of ERISA and Section 4975 of
the Code. Neither the Depositor, the Master Servicer nor the Trustee will be
required to obtain such Opinion of Counsel on behalf of any prospective
transferee. In lieu of such Opinion of Counsel, the Trustee shall require a
certification in the form of Exhibit G-6 (or in a form substantially similar to
such Exhibit G-6 as shall be agreed upon by the Trustee), in the case of the
transfer of any of the foregoing Certificates to a person capable of providing
such certification, substantially to the effect that all funds used by such
transferee to purchase such Certificates will be funds held by it in its general
account which it reasonably believes do not constitute "plan assets" of any Plan
(as defined above); provided however that such certification will not be
required in connection with any transfer of any such Certificate by the
Depositor to an affiliate of the Depositor 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 Depositor of the status of such
transferee as an affiliate of the Depositor. The permission of any transfer in
violation of the restriction on transfer set forth in this paragraph shall not
constitute a default or an Event of Default.

           (e) (i) Each Person who has or who acquires any Ownership Interest in
a Residual 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
Residual Certificate are expressly subject to the following provisions:

           (A) Each Person holding or acquiring any Ownership Interest in a
     Residual 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 Residual Certificate, the Trustee shall require delivery to
     it, and shall not register the Transfer of any Residual 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 Residual 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 Residual 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 Residual



<PAGE>


                                      -86-


     Certificate, in form and substance satisfactory to the Trustee representing
     and 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 Residual Certificate to such proposed Transferee
     shall be effected.

           (D) Each Person holding or acquiring any Ownership Interest in a
     Residual 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 Residual 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
     Residual 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 Residual Certificate, if it is "a pass-through
     interest holder", or is holding an Ownership Interest in a Residual
     Certificate on behalf of a "pass-through interest holder."

           (ii) The Trustee will register the Transfer of any Residual
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 Residual Certificates other
than to Permitted Transferees are prohibited.

           (iii) (A) If any Person other than a Permitted Transferee shall
become a Holder of a Residual 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 Residual Certificate. If a transfer of a Residual 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
Residual Certificate. The Trustee shall be under no liability to any Person for
any registration of Transfer of a Residual Certificate that is in fact not
permitted by this Section 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.



<PAGE>


                                      -87-


              (B) If any purported Transferee shall become a Holder of a
Residual 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 Residual 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 Residual Certificate,
to sell such Residual 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 Residual 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 Residual 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 Residual Certificate to any Person who is a Disqualified
Organization, including the information regarding "excess inclusions" of such
Residual 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 Residual 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.

           (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



<PAGE>


                                      -88-


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 Certi ficates.

           (i) All Certificates surrendered for transfer and exchange shall be
cancelled 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 Depositor, the Master Servicer, the Trustee, the Insurer 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 Depositor, the Master Servicer, the Trustee, the Insurer nor any
agent of any of them shall be affected by notice to the contrary.

                                   ARTICLE VI

                      THE DEPOSITOR AND THE MASTER SERVICER

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

           The Depositor 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 Depositor 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 Depositor or
                         the Master Servicer.

           The Depositor 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 Depositor or the Master Servicer may be
merged, consolidated or converted, or any corporation resulting from any merger
or consolidation to which the Depositor or the Master Servicer shall be a party,
or any Person succeeding to the business of the Depositor or the Master
Servicer, shall be the successor of the Depositor 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 Depositor, the Master
                         Servicer and Others.


           Neither the Depositor, the Master Servicer nor any of the directors,
officers, employees or agents of the Depositor 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 Depositor or the Master Servicer (but this
provision shall protect the above described persons) against any breach of
warranties or representations made herein; and provided further that this
provision shall not protect the Depositor, the Master Servicer or any such
person, against any



<PAGE>


                                      -90-


liability which would otherwise be imposed by reason of willful misfeasance, bad
faith or gross negligence in the performance of duties or by reason of reckless
disregard of obligations and duties hereunder. The Depositor, the Master
Servicer and any director, officer, employee or agent of the Depositor 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 Depositor, the Master Servicer and any director, officer,
employee or agent of the Depositor 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, 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 (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 Depositor 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 Depositor 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 lia bility 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 Depositor 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 and the Insurer upon receipt by the Trustee
of a letter from the Rating Agency that such a resignation and appointment will
not, in and of itself, result in a downgrading of the Certificates (without
regard to the Policy) or (b) upon determination that its duties hereunder are no
longer permissible under appli cable 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 and the Insurer. 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.




<PAGE>


                                      -91-


           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 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 and the Insurer (as
evidenced in a writing signed by the Trustee and the Insurer) 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 (without regard to the Policy) 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 delivered to the Master Servicer and 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, 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 the Insurer, 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




<PAGE>


                                      -93-


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

     of two (2) Business Days or (b) the Business Day immediately preceding the

     Mortgage Loans as of the first day of the first month of such twelve month
     period, or (2) the Rolling Delinquency Percentage with respect to the
     Mortgage Loans for any Distribution Date is more than 4.50%.

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 (which Voting Rights of the Class
A Certificateholders may be exercised by the Insurer without the consent of such
Holders and may only be exercised by such Holders with the prior written consent
of the Insurer so long as there does not exist a failure by the Insurer to make
a required payment under the Policy), 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 unless an Insurer Default is continuing the successor to
the Master Servicer appointed pursuant to Section 7.02 shall be acceptable to
the Insurer and 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) or (vii) hereof shall occur, the Trustee with the
consent of the Insurer shall, by notice to the Master Servicer, the Insurer and
the Depositor, 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 (and pay any related costs and expenses) with the Trustee in effecting
the termination of the Master Servicer's responsibilities and rights hereunder,



<PAGE>


                                      -94-


including, without limitation, the transfer to the Trustee or its appointed
agent 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 on 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 assigned to
and working in the Trustee's corporate trust division has actual knowledge
thereof or unless notice of any event which is in fact such an Event of Default
is received by the Trustee and such notice references the Certificates, the
Trust Fund or this Agreement.

           SECTION 7.02. Trustee to Act; Appointment of Successor.

           On and after the time the Master Servicer receives a notice of
termination pursuant to Section 7.01 (i)-(v), the Insurer may appoint a
successor Master Servicer and if the Insurer fails to do so within 30 days, 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(g)) 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 compen sation 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, the Insurer may appoint a successor Master
Servicer and if the Insurer fails to do so within 30 days, the Trustee may, if
it shall be unwilling to so act, or shall be unable to so act, 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,



<PAGE>


                                      -95-


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.

           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.

           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 the Insurer,
the 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 and the Insurer
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 Insurer or 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) or (vii)) with the written consent of the Insurer, which
consent shall not be unreasonably withheld; PROVIDED, HOWEVER, that (a) a
default or Event of Default under clause (i) of Section 7.01 may be waived with
the written consent of the Insurer, only by all of the Holders of Certificates
affected by such default or Event of Default (which Voting Rights of the Class A
Certificateholders may be exercised by the Insurer without the consent of such
Holders and may only be exercised by such Holders with the prior written consent
of the Insurer so long as there does not exist a failure by the Insurer to make
a required payment under the Policy) 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
nonconsenting Certificateholder. Upon any such waiver of a default or Event of
Default by the Insurer or the Holders representing the requisite percentage of
Voting Rights of Certificates affected by such default or Event of Default, with
the consent of the Insurer, which consent shall not be unreasonably withheld,
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 Insurer and 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 I, REMIC II
and REMIC III 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 I, REMIC
II and REMIC III under the REMIC Provisions and to prevent the imposition of any
federal, state or local income, prohibited transaction, contribution or other
tax on the Trust Fund to the extent that maintaining such status and avoiding
such taxes are reasonably within the control of the Trustee and are reasonably
within the scope of its duties under this Agreement.

           The Trustee shall furnish in a timely fashion to the Insurer such
information as the Insurer may reasonably request from time to time necessary
for the Insurer to fulfill its duties under the Policy.




<PAGE>


                                      -98-


           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
           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 Insurer or 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 rely upon and shall be 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



<PAGE>


                                      -99-


     or direction of any of the Certificateholders or the Insurer, pursuant to
     the provisions of this Agreement, unless such Certificateholders or the
     Insurer shall have offered to the Trustee reasonable security or indemnity
     against the costs, expenses and liabilities which may be incurred therein
     or thereby and the Insurer has given its consent; 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;

         (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 Insurer or
     the Holders of Certificates entitled to at least 25% of the Voting Rights
     with written consent of the Insurer; 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 or the
     Insurer 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 or
     attorneys; and

         (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.

           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 and the
representations and warranties of the Trustee in Section 8.12) shall be taken as
the statements of the Depositor 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 (other than as specifically set forth
in Section 8.12), of the Certificates (other than the signature and
authentication of the Trustee on the Certificates) or of any Mortgage Loan or
related document. The



<PAGE>


                                      -100-


Trustee shall not be accountable for the use or application by the Depositor of
any of the Certificates or of the proceeds of such Certificates, or for the use
or application of any funds paid to the Depositor 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.




<PAGE>


                                      -101-


           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 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 and the
Insurer; 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. Upon receiving such
notice of resignation, the Master Servicer shall promptly appoint a successor
trustee acceptable to the Insurer 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 then
the Insurer may appoint a successor trustee and if the Insurer fails to do so
within 30 days, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor trustee; 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.

           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 Insurer or the Master Servicer with the consent of the
Insurer, 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 Insurer or the Master Servicer with the consent
of the Insurer 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.



<PAGE>


                                      -102-


           During the continuance of an Insurer Default, 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 Depositor 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, the Insurer 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 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 national banking
association



<PAGE>


                                      -103-


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 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 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

                                      -104-


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.

                                   ARTICLE IX

                                   TERMINATION

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

                  Subject to Section 9.02, the respective obligations and
responsibilities of the Depositor, 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 Master Servicer 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), including the amounts due to the Insurer under the Insurance
Agreement, less the good faith estimate of the Master Servicer 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 Master Servicer 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); pro vided, however, that in no event shall the trust created
hereby continue beyond the earlier of (i) October 25, 2032, 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 Master
Servicer, to avoid disqualification of the REMIC I, REMIC II or REMIC III as
REMICs; and provided further, that no purchase by the Master Servicer pursuant
to clause (i) is permitted if it would result in a draw on the Policy unless the
Insurer consents in writing. In the case of any repurchase by the Master
Servicer pursuant to clause (i), the Master Servicer shall include in such
repurchase price the amount of any Advances that will be reimbursed to the
Master Servicer pursuant to Section 3.11(iii) and the Master Servicer 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 Master Servicer.

                  The right of the Master Servicer or its designee to repurchase
all Mortgage Loans pursuant to (i) above shall be conditioned upon the aggregate
Stated Principal Balance of such



<PAGE>


                                      -106-


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 Master Servicer 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.

                  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 Master Servicer'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
Master Servicer or its designee's election to repurchase, the Master Servicer 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 distribute to the Certificateholders (i)
the amount otherwise distributable on such Distribution Date, if not in
connection with the Master Servicer's election to repurchase, or (ii) if the
Master Servicer elected to so repurchase, an amount determined as follows: with
respect to the Class A Certificates, the outstanding Certificate Principal
Balance thereof, plus one month's interest thereon at the appli cable
Pass-Through Rate and any previously unpaid Accrued Certificate Interest; and
with respect to the Residual 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 Class A Certificates, subject to the priorities set forth in Section
4.01(c). 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 Master Servicer for the remaining Mortgage Loans, and the
Trustee shall execute all assignments, endorsements and other instruments
required by the Master Servicer 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 Depositor, or appoint an agent to take reasonable steps,



<PAGE>


                                      -107-


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 Residual Certificateholders shall be entitled to all unclaimed funds and
other assets which remain subject hereto.

                  SECTION 9.02. Additional Termination Requirements.

                  (a) In the event the Master Servicer repurchases the Mortgage
Loans as provided in Section 9.01, the Trust Fund shall be terminated in
accordance with the following additional re quirements, unless the Master
Servicer, 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 9.02 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 REMIC I, REMIC II or REMIC III to fail to qualify as REMICs at any time
that any Certificate is outstanding:

                  (i) The Master Servicer shall establish a 90-day liquidation
         period for REMIC I, REMIC II and REMIC III 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 Master
         Servicer also shall satisfy all of the requirements of a qualified
         liquidation for REMIC I, REMIC II and REMIC III under Section 860F of
         the Code and regulations thereunder;

                  (ii) The Master Servicer 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; and

                  (iii) If the Master Servicer or the Depositor is exercising
         its right to purchase the assets of the Trust Fund, the Master Servicer
         shall, during the 90-day liquidation period and at or prior to the
         Final Distribution Date, purchase all of the assets of the Trust Fund
         for cash; provided, however, that in the event that a calendar quarter
         ends after the commencement of the 90-day liquidation period but prior
         to the Final Distribution Date, the Master Servicer or the Depositor
         shall not purchase any of the assets of the Trust Fund prior to the
         close of that calendar quarter.

         (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 I, REMIC II and REMIC III 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-I Certificates will constitute the sole class of
"residual interest" in REMIC I, (ii) the Class R-II Certificates will constitute
the sole class of "residual interest" in REMIC II, (iii) the Class R-III
Certificates will constitute the sole class of "residual interest" in the REMIC
III, and the Class A Certificates and Class SB Certificates shall be designated
as the "regular interests" in REMIC III. The Master Servicer and the Trustee
shall not permit the creation of any "interests" (within the meaning of Section
860G of the Code) in the REMIC other than the Class A Certificates and Class SB
Certificates.

         (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 Residual 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.




<PAGE>


                                      -109-


                  (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
Residual Certificate such information as is necessary for the application of any
tax relating to the transfer of a Residual 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 Depositor 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 I, REMIC II or REMIC III 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



<PAGE>


                                      -110-


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 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, 1999, 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 I, REMIC II or
REMIC III to fail to qualify as REMICs at any time that any Certificates are
outstanding or subject either REMIC I, REMIC II or REMIC III 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 Depositor, 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 I, REMIC II or REMIC III 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 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 I, REMIC II or REMIC III 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
Insurer, the Depositor, 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 Insurer, the Depositor 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 Insurer, the Depositor and the Trustee for any taxes and costs including,
without limitation, any reasonable attorneys' fees imposed on or incurred by the
Trust Fund, the Insurer, the Depositor 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.

                            MISCELLANEOUS PROVISIONS

                  SECTION 11.01. Amendment.

                  This Agreement may be amended from time to time by the
Depositor, the Master Servicer and the Trustee, with the consent of the Insurer
and 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 with the
consent of the Insurer by the Depositor, 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 the Trust Fund pursuant to the REMIC Provisions or
cause REMIC I, REMIC II or REMIC III to fail to qualify as REMICs 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.

                                  SERIES 1999-1

     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 one- to four-family  adjustable
     interest  rate  first  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 of this Certificate by the aggregate
Initial Certificate Principal Balance 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 one- to four-family adjustable
interest rate first 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 (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


<PAGE>



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 day (or if such last day is not
a Business Day, the Business Day immediately preceding such last day) of the
month immediately preceding the month of such distribution (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 in immediately available funds (by
wire transfer or otherwise) for the account of the Holder entitled thereto if
such Holder shall have so notified the Trustee or such Paying Agent at least 5
Business Days prior to the related Record Date and such Holder is the registered
owner of Certificates the aggregate Initial Certificate Principal Balance of
which is not less than $2,500,000, or by check mailed to the address of the
Holder 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 of this Certificate is set forth above. The
Certificate Principal Balance 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").

          This Certificate is entitled to the benefits of an irrevocable and
unconditional financial guaranty insurance policy issued by Ambac Assurance
Corporation (the "Policy").

          The Certificates are limited in right of payment to certain
collections and recoveries respecting the Mortgage Loans and the Policy, 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 limitation
reimbursement to the Company and the Master Servicer of advances made, or
certain expenses incurred, by either of them.



<PAGE>



          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 662/3% of the Percentage Interests of
each Class of Certificates affected thereby and the Insurer. 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 in the City and
State of New York, 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.

          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
required to be paid to them pursuant to the Agreement following the earlier of
(i) the maturity or other liquidation of the last Mortgage Loan subject thereto
or the disposition of all property acquired upon foreclosure or deed in lieu of
foreclosure of any Mortgage Loan and (ii) the purchase by the Master Servicer
from the Trust Fund of all remaining Mortgage Loans and all property acquired in
respect of such Mortgage Loans, thereby effecting early retirement


<PAGE>



of the Certificates. The Agreement permits, but does not require, the Master
Servicer to purchase at a price determined as provided in the Agreement all
remaining Mortgage Loans and all property acquired in respect of any Mortgage
Loan; provided, that any such option may only be exercised if the Pool 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
Cut-off Date Balance.

          Reference is hereby made to the further provisions of this Certificate
set forth on the reverse hereof, which further provisions shall for all purposes
have the same effect as if set forth at this place.

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

     consisting primarily of a pool of one- to four-family  adjustable
     interest  rate  first  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 _________________ is the registered owner of the
Percentage Interest evidenced by this Certificate in certain distributions with
respect to the Trust Fund consisting primarily of an interest in a pool of one-
to four-family adjustable interest rate first 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 (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.



<PAGE>



          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 day (or if such last day is not
a Business Day, the Business Day immediately preceding such last day) of the
month immediately preceding the month of such distribution (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 SB
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 in immediately available funds (by
wire transfer or otherwise) for the account of the Holder entitled thereto if
such Holder 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 Holder 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.

          No transfer of this Class SB Certificate will be made unless such
transfer is exempt from the registration requirements of the Securities Act of
1933, as amended, and any applicable state securities laws or is made in
accordance with said Act and laws. In the event that such a transfer is to be
made, (i) the Trustee or the Company may require an opinion of counsel
acceptable to and in form and substance satisfactory to the Trustee and the
Company that such transfer is exempt (describing the applicable exemption and
the basis therefor) from or is being made pursuant to the registration
requirements of the Securities Act of 1933, as amended, and of any applicable
statute of any state and (ii) the transferee shall execute an investment letter
in the form described by the Agreement. The Holder hereof desiring to effect
such transfer shall, and does hereby agree to, indemnify the Trustee, the
Company, the Master Servicer and the Certificate Registrar acting on behalf of
the Trustee against any liability that may result if the transfer is not so
exempt or is not made in accordance with such Federal and state laws.

          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


<PAGE>



without limitation reimbursement to 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 662/3%% of the Percentage Interests of
each Class of Certificates affected thereby and the Insurer. 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 in the City and
State of New York, 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.

          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
required to be paid to them pursuant to the Agreement following the earlier of
(i) the maturity or other liquidation of the last Mortgage Loan subject thereto
or the


<PAGE>



disposition of all property acquired upon foreclosure or deed in lieu of
foreclosure of any Mortgage Loan and (ii) the purchase by the Master Servicer
from the Trust Fund of all remaining Mortgage Loans and all property acquired in
respect of such Mortgage Loans, thereby effecting early retirement of the
Certificates. The Agreement permits, but does not require, the Master Servicer
to purchase at a price determined as provided in the Agreement all remaining
Mortgage Loans and all property acquired in respect of any Mortgage Loan;
provided, that any such option may only be exercised if the Pool 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
Cut-off Date Balance.

          Reference is hereby made to the further provisions of this Certificate
set forth on the reverse hereof, which further provisions shall for all purposes
have the same effect as if set forth at this place.

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

          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

          This certifies that ______________ is the registered owner of the
Percentage Interest evidenced by this Certificate in certain distributions with
respect to a Trust Fund, consisting primarily of a pool of one- to four-family
adjustable interest rate first 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 (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

last day) of the month immediately preceding the month of such distribution (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 R-I Certificates on such Distribution Date.

          Each Holder of this Certificate will be deemed to have agreed to be
bound by the restrictions set forth in the Agreement to the effect that (i) each
person holding or acquiring any Ownership Interest in this Certificate must be a
United States Person and a Permitted Transferee, (ii) the transfer of any
Ownership Interest in this Certificate will be conditioned upon the delivery to
the Trustee of, among other things, an affidavit to the effect that it is a
United States Person and Permitted Transferee, (iii) any attempted or purported
transfer of any Ownership Interest in this Certificate in violation of such
restrictions will be absolutely null and void and will vest no rights in the
purported transferee, and (iv) if any person other than a United States Person
and a Permitted Transferee acquires any Ownership Interest in this Certificate
in violation of such restrictions, then the Company will have the right, in its
sole discretion and without notice to the Holder of this Certificate, to sell
this Certificate to a purchaser selected by the Company, which purchaser may be
the Company, or any affiliate of the Company, on such terms and conditions as
the Company may choose.

          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 Holder of
this Certificate may have additional obligations with respect to this
Certificate, including tax liabilities.

          No transfer of this Class R-__ Certificate will be made unless such
transfer is exempt from the registration requirements of the Securities Act of
1933, as amended, and any applicable state securities laws or is made in
accordance with said Act and laws. In the event that such a transfer is to be
made, (i) the Trustee or the Company may require an opinion of counsel
acceptable to and in form and substance satisfactory to the Trustee and the
Company that such transfer is exempt (describing the applicable exemption and
the basis therefor) from or is being made pursuant to the registration
requirements of the Securities Act of 1933, as amended, and of any applicable
statute of any state and (ii) the transferee shall execute an investment letter
in the form described by the Agreement. The Holder hereof desiring to effect
such transfer shall, and does hereby agree to, indemnify the Trustee, the
Company, the Master Servicer and the Certificate Registrar acting on behalf of
the Trustee against any liability that may result if the transfer is not so
exempt or is not made in accordance with such Federal and state laws.

          No transfer of this Class R-__ Certificate will be made unless the
Trustee has received either (i) an opinion of counsel acceptable to and in form
and substance satisfactory to the Trustee, the Company and the Master Servicer
with respect to the permissibility of such transfer under the Employee
Retirement Income Security Act of 1974, as amended ("ERISA"), and Section 4975
of the Internal Revenue Code (the "Code") and stating, among other things, that
the transferee's acquisition of a Class R Certificate will not constitute or
result in a non-exempt prohibited transaction under Section 406 of ERISA or
Section 4975 of the Code or (ii) a representation letter, in the form as
described by the Agreement, stating that the transferee is not an employee
benefit or


<PAGE>



other plan subject to the prohibited transaction provisions of ERISA or Section
4975 of the Code (a "Plan"), or any other person (including an investment
manager, a named fiduciary or a trustee of any Plan) acting, directly or
indirectly, on behalf of or purchasing any Certificate with "plan assets" of any
Plan.

          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 limitation
reimbursement to 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 662/3%% 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 in the City and
State of New York, 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.



<PAGE>



          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.

          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
required to be paid to them pursuant to the Agreement following the earlier of
(i) the maturity or other liquidation of the last Mortgage Loan subject thereto
or the disposition of all property acquired upon foreclosure or deed in lieu of
foreclosure of any Mortgage Loan and (ii) the purchase by the Master Servicer
from the Trust Fund of all remaining Mortgage Loans and all property acquired in
respect of such Mortgage Loans, thereby effecting early retirement of the
Certificates. The Agreement permits, but does not require, the Master Servicer
to purchase at a price determined as provided in the Agreement all remaining
Mortgage Loans and all property acquired in respect of any Mortgage Loan;
provided, that any such option may only be exercised if the Pool 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
Cut-off Date Balance.

          Reference is hereby made to the further provisions of this Certificate
set forth on the reverse hereof, which further provisions shall for all purpose
have the same effect as if set forth at this place.

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

Ladies and Gentlemen:

          _____________________ (the "Purchaser") intends to purchase from

and warrants to, and covenants with, the Company and the Trustee that:

               1. The Purchaser understands that (a) the Certificates have not
          been and will not be registered or qualified under the Securities Act
          of 1933, as amended (the "Act") or any state securities law, (b) the
          Company is not required to so register or qualify the Certificates,

                  Mortgage Pass-Through Certificates
                  Series 1999-1, 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 1999-1, Class R-__ (the "Certificates"), issued pursuant to
Section 5.02 of the Pooling and Servicing Agreement (the "Pooling and Servicing
Agreement"), dated as of September 1, 1999, among Impac Secured Assets Corp., as
seller (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- 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


<PAGE>



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,

                    FORM OF TRANSFER AFFIDAVIT AND AGREEMENT



STATE OF                     )
                       : ss.:
COUNTY OF                    )


          ___________________, being first duly sworn, deposes, represents and
warrants:

          1. That he/she is [Title of Officer] of [Name of Owner], a [savings
institution] [corporation] duly organized and existing under the laws of [the
State of ___________] [the United States], (the "Owner"), (record or beneficial
owner of the Class R-__ Certificates on behalf of which he/she makes this
affidavit and agreement). This Class R-__ Certificate was issued pursuant to the
Pooling and Servicing Agreement (the "Pooling and Servicing Agreement") dated as
of September 1, 1999 among Impac Secured Assets Corp., as depositor, Impac
Funding Corporation, as master servicer (the "Master Servicer"), and Bankers
Trust Company of California, N.A., as trustee (the "Trustee").

          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 the Federal Home Loan Mortgage Corporation, 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 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


<PAGE>



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(e) 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(e) 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(e)). 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 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.



<PAGE>



          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, 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 purchase of Certificates is permissible under applicable law,
will not constitute or result in any prohibited transaction under ERISA or
Section 4975 of the Code, will not subject the Company, the Trustee or the
Master Servicer to any obligation in addition to those undertaken in the Pooling
and Servicing Agreement and, with respect to each source of funds ("Source")
being used by the Purchaser to acquire the Certificates, each of the following
statements are accurate: (a) the Purchaser is an insurance company; (b) the
Source is assets of the Purchaser's "general account;" (c) the conditions set
forth in Sections I and III of Prohibited Transaction Class Exemption ("PTCE")
95-60 issued by the DOL have been satisfied and the purchase, holding and
transfer of Certificates by or on behalf of the Purchaser are exempt under PTCE
95-60; and (d) the amount of reserves and liabilities for such general account
contracts held by or on behalf of any Plan do not exceed 10% of the total
reserves and liabilities of such general account plus surplus as of the date
hereof (for purposes of this clause, all Plans maintained by the same employer
(or affiliate thereof) or employee organization are deemed to be a single Plan)
in connection with its purchase and holding of such Certificates; or

          (c) 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), (b) or (c) above.

     Capitalized terms used but not defined herein shall have the meanings
assigned in the Pooling and Servicing Agreement.

          Mortgage Loan is 30 or more days past due;

          is a first priority lien on the related

          been properly designated and currently so serves and is named in the
          Mortgage or if no duly qualified trustee has been properly designated

     (q)  neither the Seller nor any servicer of the related Mortgage Loans has
          advanced funds or knowingly received any advance of funds by a party
          other than the Mortgagor, directly or indirectly, for the payment of
          any amount required by the Mortgage, except for (i) interest accruing

          bankruptcy, insolvency, reorganization or other similar laws affecting
          the enforcement of creditors' rights generally and by general equity
          principles (regardless of whether such enforcement is considered in a
          proceeding in equity or at law); and, to the best of Seller's
          knowledge, all parties to each Mortgage Note and the Mortgage had
          legal capacity to execute the Mortgage Note and the Mortgage and each

          Loan to, any of them, or any servicing agent of any of the foregoing;

          of the benefits of the security, including realization by judicial,
          or, if applicable, non-judicial foreclosure, and, to Seller's

          Mortgagor which would interfere with such right to foreclosure;

          been fully disbursed, there is no requirement for future advances

          under a standard extended coverage endorsement in the locale in which
          the Mortgaged Property is located, in an amount which is not less than
          the lesser of the maximum insurable value of the improvements securing
          such Mortgage Loan or the outstanding principal balance of the
          Mortgage Loan, but in no event in an amount less than an amount that
          is required to prevent the Mortgagor from being deemed to be a
          co-insurer thereunder; if the improvement on the Mortgaged Property is
          a condominium unit, it is included under the coverage afforded by a
          blanket policy for the condominium project; if upon origination of the
          related Mortgage Loan, the improvements on the Mortgaged Property were
          in an area identified as a federally designated flood area, a flood
          insurance policy is in effect in an amount representing coverage not

          the related Mortgage Note and there is no material event which, with
          the passage of time or with notice and the expiration of any grace or
          cure period, would constitute a default, breach or event of
          acceleration; and neither the Seller, any of its affiliates nor any
          servicer of any related Mortgage Loan has taken any action to waive
          any material default, breach or event of acceleration; no foreclosure
          action is threatened or has been commenced with respect to the
