           (each such endorsement being sufficient to transfer all right, title

           thereof, in and to that Mortgage Note);

                     (ii) except as provided below, the original recorded
           Mortgage with evidence of a recording thereon, or if any such
           Mortgage has not been returned from the applicable recording office
           or has been lost, or if such public recording office retains the
           original recorded Mortgage, a copy of such Mortgage certified by the
           Seller as being a true and correct copy of the Mortgage;

                     (iii) subject to the proviso at the end of this paragraph,

           included in a blanket assignment or assignments), together with,
           except as provided below, originals of all interim recorded
           assignments of such mortgage or a copy of such interim assignment
           certified by the Seller as being a true and complete copy of the
           original recorded intervening assignments of Mortgage (each such
           assignment, when duly and validly completed, to be in recordable form
           and sufficient to effect the assignment of and transfer to the
           assignee thereof, under the Mortgage to which the assignment
           relates); provided that, if the related Mortgage has not been
           returned from the applicable public recording office, such Assignment
           of Mortgage may exclude the information to be provided by the
           recording office;

                     (iv) the originals of all assumption, modification,
           consolidation or extension agreements, if any, with evidence of
           recording thereon, if any;

                      (v) the original or duplicate original mortgagee title
           insurance policy and all riders thereto;

                      (vi) the original of any guarantee executed in connection
           with the Mortgage Note; and


                                       26
<PAGE>   33

                     (vii) the original of any security agreement, chattel
           mortgage or equivalent document executed in connection with the
           Mortgage;

provided, however, that on the Closing Date, with respect to item (iii), the
Sponsor has delivered to the Trustee a copy of such Assignment of Mortgage in
blank and has caused the Master Servicer to retain the completed Assignment of
Mortgage for recording as described below. In addition, if the Sponsor is unable
to deliver or cause the delivery of any original Mortgage Note due to the loss
of such original Mortgage Note, the Sponsor may deliver a copy of such Mortgage
Note, together with a lost note affidavit, and shall thereby be deemed to have
satisfied the document delivery requirements of this 2.01(b).

           If in connection with any Mortgage Loans, the Sponsor cannot deliver
(A) the Mortgage, (B) all interim recorded assignments, (C) all assumption,
modification, consolidation or extension agreements, if any, or (D) the lender's
title policy (together with all riders thereto) satisfying the requirements of
clause (ii), (iii), (iv) or (v) above, respectively, concurrently with the
execution and delivery hereof because such document or documents have not been
returned from the applicable public recording office in the case of clause (ii),
(iii) or (iv) above, or because the title policy has not been delivered to
either the Master Servicer or the Sponsor by the applicable title insurer in the
case of clause (v) above, the Sponsor shall promptly deliver or cause to be
delivered to the Trustee or the Custodian on behalf of the Trustee, in the case
of clause (ii), (iii) or (iv) above, such Mortgage, such interim assignment or
such assumption, modification, consolidation or extension agreement, as the case
may be, with evidence of recording indicated thereon upon receipt thereof from
the public recording office, but in no event shall any such delivery of any such
documents or instruments be made later than one year following the Closing Date,
unless, in the case of clause (ii), (iii) or (iv) above, there has been a
continuing delay at the applicable recording office or, in the case of clause
(v), there has been a continuing delay at the applicable insurer and the Sponsor
has delivered the Officer's Certificate to such effect to the Trustee. The
Sponsor shall forward or cause to be forwarded to the Trustee (1) from time to
time additional original documents evidencing an assumption or modification of a
Mortgage Loan and (2) any other documents required to be delivered by the
Sponsor or the Master Servicer to the Trustee or the Custodian on the Trustee's
behalf. In the event that the original Mortgage is not delivered and in
connection with the payment in full of the related Mortgage Loan the public
recording office requires the presentation of a "lost instruments affidavit and
indemnity" or any equivalent document, because only a copy of the Mortgage can
be delivered with the instrument of satisfaction or reconveyance, the Master
Servicer shall prepare, execute and deliver or cause to be prepared, executed
and delivered, on behalf of the Trust, such a document to the public recording
office.

           As promptly as practicable subsequent to such transfer and
assignment, and in any event, within 30 days thereafter, the Master Servicer
shall (I) cause each Assignment of Mortgage to be in proper form for recording
in the appropriate public office for real property records within 30 days of the
Closing Date and (II) at the Sponsor's expense, cause to be delivered for
recording in the appropriate public office for real property records the
Assignments of the Mortgages to the Trustee, except that, with respect to any
Assignment of a Mortgage as to which the Master Servicer has not received the
information required to prepare such assignment in recordable form, the Master
Servicer's obligation to do so and to deliver the same for such recording shall
be as soon as 



                                       27
<PAGE>   34

practicable after receipt of such information and in any event within 30 days
after the receipt thereof.

           In the case of Mortgage Loans that have been prepaid in full as of
the Closing Date, the Sponsor, in lieu of delivering the above documents to the
Trustee, or the Custodian on the Trustee's behalf, will cause the Master
Servicer to deposit in the Collection Account the portion of such payment that
is required to be deposited in the Collection Account pursuant to Section 3.08.

           SECTION 2.02. Acceptance by the Trustee of the Mortgage Loans.
Subject to the provisions of the following paragraph, the Trustee declares that
it, or the Custodian as its agent, will hold the documents referred to in
Section 2.01 and the other documents delivered to it constituting the Mortgage
Files, and that it will hold such other assets as are included in the Trust
Fund, in trust for the exclusive use and benefit of all present and future
Certificateholders.

           Upon execution and delivery of this document, the Trustee shall
deliver to the Sponsor and the Master Servicer a certification in the form of
Exhibit M hereto (the "Initial Certification") to the effect that, except as may
be specified in a list of exceptions attached thereto: (a) it, or the Custodian
as its agent, has received the original Mortgage Note relating to each of the
Mortgage Loans listed on the Mortgage Loan Schedule, and (b) each Mortgage Note
purports to be that of the Mortgagor.

           Within 90 days after the execution and delivery of this Agreement,
the Trustee shall review, or cause the Custodian to review, the Mortgage Files
in its possession, and shall deliver to the Sponsor and the Master Servicer a
certification in the form of Exhibit N hereto (the "Final Certification") to the
effect that, as to each Mortgage Loan listed in the Mortgage Loan Schedule,
except as may be specified in a list of exceptions attached to such Final
Certification, such Mortgage File contains all of the items required to be
delivered pursuant to Section 2.01(b).

           If, in the course of such review, the Trustee or the Custodian finds
any document constituting a part of a Mortgage File which does not meet the
requirements of Section 2.01 or is omitted from such Mortgage File, the Trustee
shall promptly so notify the Master Servicer, the Seller and the Sponsor, or
shall cause the Custodian to promptly so notify the Master Servicer, the Seller
and the Sponsor. In performing any such review, the Trustee or the Custodian may
conclusively rely on the purported genuineness of any such document and any
signature thereon. It is understood that the scope of the Trustee's or the
Custodian's review of the Mortgage Files is limited solely to confirming that
the documents listed in Section 2.01 have been received and further confirming
that any and all documents delivered pursuant to Section 2.01 have been executed
and relate to the Mortgage Loans identified in the Mortgage Loan Schedule.
Neither the Trustee nor the Custodian shall have any responsibility for
determining whether any document is valid and binding, whether the text of any
assignment or endorsement is in proper or recordable form, whether any document
has been recorded in accordance with the requirements of any applicable
jurisdiction, or whether a blanket assignment is permitted in any applicable
jurisdiction. The Master Servicer shall cause the Seller, in accordance with the
terms and provisions of Subsection 7.03 of the Sale Agreement, to promptly
correct or cure such defect within 90 days from the date it was so notified of
such defect and, if the Seller does not correct or cure such defect within such
period, the Master Servicer shall cause the Seller to either (a) substitute for
the related 



                                       28

Mortgage Loan a Substitute Mortgage Loan, which substitution shall be
accomplished in the manner and subject to the conditions set forth in Section
2.03(c), or (b) purchase such Mortgage Loan from the Trustee at the Purchase
Price for such Mortgage Loan, in either case within 90 days from the date the
Seller was notified of such defect in writing; provided, however, that in no
event shall such a substitution occur more than two years from the Closing Date,
unless the Seller shall have provided to the Trustee an Opinion of Counsel to
the effect that such later substitution will not affect the REMIC status of the
Trust Fund.

           The Trustee shall retain or shall cause the Custodian to retain
possession and custody of each Mortgage File in accordance with and subject to
the terms and conditions set forth herein. The Master Servicer shall promptly
deliver to the Trustee, upon the execution or, in the case of documents
requiring recording, receipt thereof, the originals of such other documents or
instruments constituting the Mortgage File as come into the possession of the
Master Servicer from time to time.

           It is understood and agreed that the obligation of the Seller,
pursuant to Subsection 7.03 of the Sale Agreement, to substitute for or to
purchase any Mortgage Loan which does not meet the requirements of Section 2.01
shall constitute the sole remedy respecting such defect available to the
Trustee, the Sponsor and any Certificateholder against the Seller.

           The Trustee or the Custodian, on behalf of the Trustee, shall be
under no duty or obligation (i) to inspect, review or examine any such
documents, instruments, certificates or other papers to determine that they are
genuine, enforceable, or appropriate for the represented purpose or that they
are other than what they purport to be on their face or (ii) to determine
whether any Mortgage File should include any of the documents specified in
Section 2.01(b)(iv), (vi) and (vii).

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

           (a) The Master Servicer hereby makes the following representations
and warranties to the Sponsor and the Trustee, as of the Closing Date:

                     (i) The Master Servicer is a corporation duly organized,
           validly existing, and in good standing under the laws of the State of
           Texas and has all licenses necessary to carry on its business as now
           being conducted and is licensed, qualified and in good standing in
           each of the states where a Mortgaged Property is located if the laws
           of such state require licensing or qualification in order to conduct
           business of the type conducted by the Master Servicer. The Master
           Servicer has corporate power and authority to execute and deliver
           this Agreement and to perform in accordance herewith; the execution,
           delivery and performance of this Agreement (including all instruments
           of transfer to be delivered pursuant to this Agreement) by the Master
           Servicer and the consummation of the transactions contemplated hereby
           have been duly and validly authorized. This Agreement, assuming due
           authorization, execution and delivery by the other parties hereto,
           evidences the valid, binding and enforceable obligation of the Master
           Servicer, subject to applicable law except as enforceability may be
           limited by (A) bankruptcy, insolvency, liquidation, receivership,
           moratorium, reorganization or other similar laws affecting the
           enforcement of the rights of creditors and (B) general principles 



                                       29
<PAGE>   36

           of equity, whether enforcement is sought in a proceeding in equity or
           at law. All requisite corporate action has been taken by the Master
           Servicer to make this Agreement valid and binding upon the Master
           Servicer in accordance with its terms.

                     (ii) No consent, approval, authorization or order is
           required for the transactions contemplated by this Agreement from any
           court, governmental agency or body, or federal or state regulatory
           authority having jurisdiction over the Master Servicer is required
           or, if required, such consent, approval, authorization or order has
           been or will, prior to the Closing Date, be obtained.

                     (iii) The consummation of the transactions contemplated by
           this Agreement are in the ordinary course of business of the Master
           Servicer and will not result in the breach of any term or provision
           of the charter or by-laws of the Master Servicer or result in the
           breach of any term or provision of, or conflict with or constitute a
           default under or result in the acceleration of any obligation under,
           any agreement, indenture or loan or credit agreement or other
           instrument to which the Master Servicer or its property is subject,
           or result in the violation of any law, rule, regulation, order,
           judgment or decree to which the Master Servicer or its property is
           subject.

                     (iv) There is no action, suit, proceeding or investigation
           pending or, to the best knowledge of the Master Servicer, threatened
           against the Master Servicer which, either individually or in the
           aggregate, would result in any material adverse change in the
           business, operations, financial condition, properties or assets of
           the Master Servicer, or in any material impairment of the right or
           ability of the Master Servicer to carry on its business substantially
           as now conducted or which would draw into question the validity of
           this Agreement or the Mortgage Loans or of any action taken or to be
           taken in connection with the obligations of the Master Servicer
           contemplated herein, or which would materially impair the ability of
           the Master Servicer to perform under the terms of this Agreement.

                     (v) The Master Servicer is working to modify its computer
           and other systems used in servicing the Mortgage Loans to operate in
           a manner such that, on and after January 1, 2000, the Master Servicer
           can service the Mortgage Loans in accordance with the terms of this
           Agreement.

           (b) The Seller has made certain representations and warranties with
respect to the Mortgage Loans in Subsection 7.01 of the Sale Agreement, and such
representations and warranties were assigned to the Sponsor pursuant to the
Assignment. The Sponsor hereby assigns such representations and warranties
(together with any rights to cure breaches with respect thereto) to the Trustee
for the benefit of the Certificateholders.

           (c) Upon discovery by any of the parties hereto of a breach of any of
the foregoing representations or warranties, or a breach of a representation or
warranty made pursuant to Subsection 7.01 of the Sale Agreement that materially
and adversely affects the value of any Mortgage Loan or the interests of the
Certificateholders in any Mortgage Loan, the party discovering such breach shall
give prompt notice thereof to the other parties hereto and to the Seller. 



                                       30
<PAGE>   37

In accordance with the terms and provisions of Subsection 7.03 of the Sale
Agreement, the Master Servicer shall cause the Seller to, within 90 days of the
earlier of its discovery or its receipt of written notice from any party of a
breach of any representation or warranty made pursuant to Subsection 7.01 of the
Sale Agreement which materially and adversely affects the value of any Mortgage
Loan or interests of the Certificateholders in any Mortgage Loan, cure such
breach in all material respects, and if such breach is not so cured, shall, (i)
if such action is taken within the two-year period following the Closing Date,
remove such Mortgage Loan from the Trust Fund and substitute in its place a
Substitute Mortgage Loan, in the manner and subject to the conditions set forth
in this Section 2.03(c); or (ii) purchase the affected Mortgage Loan or Mortgage
Loans from the Trustee at the Purchase Price in the manner set forth below.

           With respect to each Substitute Mortgage Loan, the Master Servicer
shall cause the Seller to deliver to the Trustee, for the benefit of the
Certificateholders, the Mortgage Note, the Mortgage, the related Assignment of
Mortgage, and such other documents and agreements as are otherwise required by
Section 2.01, with the Mortgage Note endorsed and the Mortgage assigned as
required by Section 2.01. No substitution is permitted to be made in any
calendar month after the Determination Date for such month. Monthly Payments due
with respect to any Substitute Mortgage Loan in the month of substitution shall
not be part of the Trust Fund and will be retained by the Seller. For the month
of substitution, distributions to Certificateholders will include the Monthly
Payment due on any Defective Mortgage Loan for such month and thereafter the
Seller shall be entitled to retain all amounts received in respect of such
Defective Mortgage Loan.

           The Master Servicer shall amend the Mortgage Loan Schedule for the
benefit of the Certificateholders to reflect the removal of a Defective Mortgage
Loan and the substitution of the Substitute Mortgage Loan or Loans and the
Master Servicer shall deliver the amended Mortgage Loan Schedule to the Trustee
and the Custodian. Upon such substitution, each Substitute Mortgage Loan shall
be subject to the terms of this Agreement in all respects, and the Seller shall
be deemed to have made to the Trustee with respect to such Substitute Mortgage
Loan, as of the date of substitution, the representations and warranties made
pursuant to Subsection 7.01 of the Sale Agreement. Upon any such substitution
and the deposit to the Collection Account of any required Substitution
Adjustment Amount (as described in the next paragraph) and receipt of a Request
for Release, the Trustee shall release, or shall direct the Custodian to
release, the Mortgage File relating to such Defective Mortgage Loan to the
Seller and shall execute and deliver at the Seller's direction such instruments
of transfer or assignment prepared by the Seller, in each case without recourse,
as shall be necessary to vest title in the Seller, or its designee, the
Trustee's interest in any Defective Mortgage Loan substituted for pursuant to
this Section 2.03(c).

           For any month in which the Seller substitutes one or more Substitute
Mortgage Loans for one or more Defective Mortgage Loans, the Master Servicer
will determine the amount (if any) by which the aggregate principal balance of
all such Substitute Mortgage Loans as of the date of substitution is less than
the aggregate Stated Principal Balance of all such Defective Mortgage Loans
(after application of the principal portion of the Monthly Payments due in the
month of substitution). The amount of such shortage (the "Substitution
Adjustment Amount") plus an amount equal to the aggregate of any unreimbursed
Advances with respect to such Defective Mortgage Loans shall be deposited into
the Collection Account by the Seller on or before the 



                                       31
<PAGE>   38

Distribution Account Deposit Date for the Distribution Date in the month
succeeding the calendar month during which the related Mortgage Loan is required
to be purchased or replaced hereunder.

           If the Seller repurchases a Defective Mortgage Loan, the Purchase
Price therefor shall be deposited in the Collection Account pursuant to Section
3.08(b)(vi) on or before the Distribution Account Deposit Date for the
Distribution Date in the month following the month during which the Seller
became obligated to repurchase or substitute for such Mortgage Loan and upon
such deposit of the Purchase Price, and receipt of a Request for Release, the
Trustee, or the Custodian on behalf of the Trustee, shall release the related
Mortgage File held for the benefit of the Certificateholders to the Seller, and
the Trustee shall execute and deliver at the Seller's direction such instruments
of transfer or assignment prepared by the Seller, in each case without recourse,
as shall be necessary to transfer title from the Trustee. It is understood and
agreed that the obligation of the Seller, pursuant to Subsection 7.03 of the
Sale Agreement, to cure, repurchase or substitute for any Mortgage Loan as to
which a breach has occurred and is continuing shall constitute the sole remedy
against the Seller respecting such breach available to Certificateholders, the
Sponsor or the Trustee on their behalf.

           The representations and warranties made or assigned pursuant to this
Section 2.03 shall survive delivery of the respective Mortgage Files to the
Trustee for the benefit of the Certificateholders.

           SECTION 2.04. Representations and Warranties of the Sponsor as to the
Mortgage Loans. The Sponsor hereby represents and warrants to the Trustee with
respect to each Mortgage Loan as of the date hereof or such other date set forth
herein that as of the Closing Date, and following the transfer of the Mortgage
Loans to it by the Seller, the Sponsor had good title to the Mortgage Loans and
the Mortgage Notes were subject to no offsets, defenses or counterclaims.

           The Sponsor hereby assigns, transfers and conveys to the Trustee all
of its rights with respect to the Mortgage Loans including, without limitation,
the representations and warranties of the Seller made pursuant to Subsection
7.01 of the Sale Agreement, together with all rights of the Sponsor to require
the Seller to cure any breach thereof or to repurchase or substitute for any
affected Mortgage Loan in accordance with the Sale Agreement.

           It is understood and agreed that the representations and warranties
set forth in this Section 2.04 shall survive delivery of the Mortgage Files to
the Trustee. Upon discovery by the Master Servicer, the Sponsor or the Trustee
of a breach of any of the foregoing representations and warranties set forth in
this Section 2.04, which breach materially and adversely affects the interest of
the Certificateholders, the party discovering such breach shall give prompt
written notice to the other parties hereto and to each Rating Agency.

           SECTION 2.05. Designation of Interests in REMIC. The Preliminary
Statement sets forth the designations for federal income tax purposes of all
interests created hereby. The "tax matters person" with respect to the REMIC
hereunder shall be the Holder of the applicable Residual Certificate. The Tax
Matters Person of the REMIC hereby appoints the Trustee as its agent to perform
all acts required to be performed by the Tax Matters Person and to prepare and
file all necessary tax forms and reports. The REMIC's fiscal year shall be the
calendar year.

           SECTION 2.06. Designation of Start-up Day. The Closing Date is hereby
designated as the "start-up day" of the REMIC within the meaning of Section
860G(a)(9) of the Code.

           SECTION 2.07. REMIC Certificate Maturity Date. Solely for purposes of
satisfying Section 1.860G-1(a)(4)(iii) of the Treasury Regulations, the "latest
possible maturity date" of the Regular Certificates is the Distribution Date in
September 2031.

           SECTION 2.08. Repurchases for Tax Violations. Upon discovery by the
Sponsor, the Seller, the Master Servicer, or the Trustee that any Mortgage Loan
does not constitute a "qualified mortgage" within the meaning of Section
860G(a)(3) of the Code, the party discovering such fact shall promptly (and in
any event within five Business Days of discovery) give written notice thereof to
the other parties. In connection therewith, the Trustee shall require the Seller
pursuant to the terms of the Sale Agreement, at the Seller's option, to either
(a) substitute, if the conditions in Section 2.03(c) with respect to
substitutions are satisfied, a Substitute Mortgage Loan for the affected
Mortgage Loan, or (b) purchase the affected Mortgage Loan within 90 days of such
discovery in the same manner as it would a Mortgage Loan for a breach of
representation or warranty made pursuant to Subsection 7.01 of the Sale
Agreement and in accordance with Section 2.03. The Trustee shall reconvey to the
Seller the Mortgage Loan to be released pursuant hereto in the same manner, and
on the same terms and conditions, as it would a Mortgage Loan purchased for
breach of a representation or warranty pursuant to Subsection 7.01 of the Sale
Agreement and in accordance with Section 2.03.

           SECTION 2.09. Execution and Delivery of Certificates. The Trustee
acknowledges the transfer and assignment to it of the Trust Fund and the
creation of the Trust, and, concurrently with such transfer and assignment, the
Trustee has executed and delivered to or upon the order of the Sponsor, the
Certificates in authorized denominations evidencing directly or indirectly the
entire ownership of the Trust. The Trustee agrees to hold the Trust Fund and
exercise the rights referred to above for the benefit of all present and future
Holders of the Certificates and to perform the duties set forth in this
Agreement to the end that the interests of the Holders of the Certificates may
be adequately and effectively protected.


                                   ARTICLE III
                          ADMINISTRATION AND SERVICING
                                OF MORTGAGE LOANS

           SECTION 3.01. Master Servicer to Service Mortgage Loans. For and on
behalf of the Certificateholders, the Master Servicer shall service and
administer the Mortgage Loans in 



                                       33
<PAGE>   40

accordance with the terms of this Agreement, Customary Servicing Procedures,
applicable law and the terms of the Mortgage Notes and Mortgages. In connection
with such servicing and administration, the Master Servicer shall have full
power and authority, acting alone and/or through Servicers as provided in
Section 3.02, to do or cause to be done any and all things that it may deem
necessary or desirable in connection with such servicing and administration
including, but not limited to, the power and authority, subject to the terms
hereof, (a) to execute and deliver, on behalf of the Certificateholders and the
Trustee, customary consents or waivers and other instruments and documents, (b)
to consent to transfers of any Mortgaged Property and assumptions of the
Mortgage Notes and related Mortgages (but only in the manner provided in this
Agreement), (c) to collect any Insurance Proceeds and other Liquidation
Proceeds, and (d) to effectuate foreclosure or other conversion of the ownership
of the Mortgaged Property securing any Mortgage Loan. The Master Servicer shall
represent and protect the interests of the Trust in the same manner as it
protects its own interests in mortgage loans in its own portfolio in any claim,
proceeding or litigation regarding a Mortgage Loan and shall not make or permit
any modification, waiver or amendment of any term of any Mortgage Loan, except
as provided pursuant to Section 3.21. Without limiting the generality of the
foregoing, the Master Servicer, in its own name or in the name of any Servicer
or the Sponsor and the Trustee, is hereby authorized and empowered by the
Sponsor and the Trustee, when the Master Servicer or the Servicer, as the case
may be, believes it appropriate in its reasonable judgment, to execute and
deliver, on behalf of the Trustee, the Sponsor, the Certificateholders or any of
them, any and all instruments of satisfaction or cancellation, or of partial or
full release or discharge, and all other comparable instruments, with respect to
the Mortgage Loans, and with respect to the Mortgaged Properties held for the
benefit of the Certificateholders. The Master Servicer shall prepare and deliver
to the Sponsor and/or the Trustee such documents requiring execution and
delivery by either or both of them as are necessary or appropriate to enable the
Master Servicer to service and administer the Mortgage Loans to the extent that
the Master Servicer is not permitted to execute and deliver such documents
pursuant to the preceding sentence. Upon receipt of such documents, the Sponsor
and/or the Trustee shall promptly execute such documents and deliver them to the
Master 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 Servicing Advances shall be reimbursable in the first instance
from related collections from the Mortgagors pursuant to Section 3.09, and
further as provided in Section 3.11. The costs incurred by the Master Servicer,
if any, in effecting the timely payments of taxes and assessments on the
Mortgaged Properties and related insurance premiums shall not, for the purpose
of calculating monthly distributions to the Certificateholders, be added to the
Stated Principal Balances of the related Mortgage Loans, notwithstanding that
the terms of such Mortgage Loans so permit.

           The relationship of the Master Servicer (and of any successor to the
Master Servicer as 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.

<PAGE>   41

           SECTION 3.02. Subservicing; Enforcement of the Obligations of
Servicers.

           (a) The Master Servicer may arrange for the subservicing of any
Mortgage Loan by a Servicer pursuant to a Servicing Agreement; provided,
however, that such subservicing arrangement and the terms of the related
Servicing Agreement must provide for the servicing of such Mortgage Loan in a
manner consistent with the servicing arrangements contemplated hereunder.
Notwithstanding the provisions of any Servicing Agreement, any of the provisions
of this Agreement relating to agreements or arrangements between the Master
Servicer and a Servicer or reference to actions taken through a Servicer or
otherwise, the Master Servicer shall remain obligated and liable to the Sponsor,
the Trustee and the Certificateholders for the servicing and administration of
the Mortgage Loans in accordance with the provisions of this Agreement without
diminution of such obligation or liability by virtue of such Servicing
Agreements or arrangements or by virtue of indemnification from the 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. All actions
of each Servicer performed pursuant to the related Servicing Agreement shall be
performed as agent of the Master Servicer with the same force and effect as if
performed directly by the Master Servicer.

           (b) For purposes of this Agreement, the Master Servicer shall be
deemed to have received any collections, recoveries or payments with respect to
the Mortgage Loans that are received by a Servicer regardless of whether such
payments are remitted by the Servicer to the Master Servicer.

           (c) As part of its servicing activities hereunder, the Master
Servicer, for the benefit of the Trustee and the Certificateholders, shall use
its best reasonable efforts to enforce the obligations of each Servicer under
the related Servicing Agreement, to the extent that the non-performance of any
such obligation would have a material and adverse effect on a Mortgage Loan.
Such enforcement, including, without limitation, the legal prosecution of
claims, termination of 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, and shall be reimbursed
therefor only (i) from a general recovery resulting from such enforcement to the
extent, if any, that such recovery exceeds all amounts due in respect of the
related Mortgage Loan or (ii) from a specific recovery of costs, expenses or
attorneys fees against the party against whom such enforcement is directed.

           (d) Any Servicing Agreement entered into by the Master Servicer shall
provide that it may be assumed or terminated by the Trustee, if the Trustee has
assumed the duties of the Master Servicer, or any successor Master Servicer, at
the Trustee's or successor Master Servicer's option, as applicable, without cost
or obligation to the assuming or terminating party or the Trust Fund, upon the
assumption by such party of the obligations of the Master Servicer pursuant to
Section 8.05.

           Any Servicing Agreement, and any other transactions or services
relating to the Mortgage Loans involving a Servicer, shall be deemed to be
between the Master Servicer and such Servicer 



                                       35
<PAGE>   42

alone, and the Trustee and the Certificateholders shall not be deemed parties
thereto and shall have no claims or rights of action against, rights,
obligations, duties or liabilities to or with respect to the Servicer or its
officers, directors or employees, except as set forth in Section 3.01.

           SECTION 3.03. Fidelity Bond; Errors and Omissions Insurance. The
Master Servicer shall maintain, at its own expense, a blanket fidelity bond and
an errors and omissions insurance policy, with broad coverage on all officers,
employees or other persons acting in any capacity requiring such persons to
handle funds, money, documents or papers relating to the Mortgage Loans. These
policies must insure the Master Servicer against losses resulting from dishonest
or fraudulent acts committed by the Master Servicer's personnel, any employees
of outside firms that provide data processing services for the Master Servicer,
and temporary contract employees or student interns. Such fidelity bond shall
also protect and insure the Master Servicer against losses in connection with
the release or satisfaction of a Mortgage Loan without having obtained payment
in full of the indebtedness secured thereby. No provision of this Section 3.03
requiring such fidelity bond and errors and omissions insurance shall diminish
or relieve the Master Servicer from its duties and obligations as set forth in
this Agreement. The minimum coverage under any such bond and insurance policy
shall be at least equal to the corresponding amounts required by FNMA in the
FNMA Servicing Guide or by FHLMC in the FHLMC Sellers' & Servicers' Guide, as
amended or restated from time to time, or in an amount as may be permitted to
the Master Servicer by express waiver of FNMA or FHLMC.

           SECTION 3.04. Access to Certain Documentation. The Master Servicer
shall provide to the OTS and the FDIC and to comparable regulatory authorities
supervising Holders of Subordinate Certificates and the examiners and
supervisory agents of the OTS, the FDIC and such other authorities, access to
the documentation regarding the Mortgage Loans required by applicable
regulations of the OTS and the FDIC. Such access shall be afforded without
charge, but only upon reasonable and prior written request and during normal
business hours at the offices designated by the Master Servicer. Nothing in this
Section 3.04 shall limit the obligation of the Master Servicer to observe any
applicable law and the failure of the Master Servicer to provide access as
provided in this Section 3.04 as a result of such obligation shall not
constitute a breach of this Section 3.04.

           SECTION 3.05. Maintenance of Primary Mortgage Insurance Policy;
Claims. With respect to each Mortgage Loan with an LTV in excess of 80% or such
other LTV as may be required by law, the Master Servicer shall, without any cost
to the Trust Fund, maintain or cause the Mortgagor to maintain in full force and
effect a Primary Insurance Policy insuring that portion of the Mortgage Loan in
excess of a percentage in conformity with FNMA requirements. The Master Servicer
shall pay or shall cause the Mortgagor to pay the premium thereon on a timely
basis, at least until the LTV of such Mortgage Loan is reduced to 80% or such
other LTV as may be required by law. If such Primary Insurance Policy is
terminated, the Master Servicer shall obtain from another insurer a comparable
replacement policy, with a total coverage equal to the remaining coverage of
such terminated Primary Insurance Policy. If the insurer shall cease to be an
insurer acceptable to FNMA, the Master Servicer shall notify the Trustee in
writing, it being understood that the Master Servicer shall not have any
responsibility or liability for any failure to recover under the Primary
Insurance Policy for such reason. If the Master Servicer determines that
recoveries under the Primary Insurance Policy are jeopardized by the financial
condition of the insurer, the Master Servicer shall obtain from another insurer
which meets the requirements of this Section 3.05 



                                       36
<PAGE>   43

a replacement insurance policy. The Master Servicer shall not take any action
that would result in noncoverage under any applicable Primary Insurance Policy
of any loss that, but for the actions of the Master Servicer, would have been
covered thereunder. In connection with any assumption or substitution agreement
entered into or to be entered into pursuant to Section 3.13, the Master Servicer
shall promptly notify the insurer under the related Primary Insurance Policy, if
any, of such assumption or substitution of liability in accordance with the
terms of such Primary Insurance Policy and shall take all actions which may be
required by such insurer as a condition to the continuation of coverage under
such Primary Insurance Policy. If such Primary Insurance Policy is terminated as
a result of such assumption or substitution of liability, the Master Servicer
shall obtain a replacement Primary Insurance Policy as provided above.

           In connection with its activities as master servicer, the Master
Servicer agrees to prepare and present, on behalf of itself, the Trustee and the
Certificateholders, claims to the insurer under any Primary Insurance Policy in
a timely fashion in accordance with the terms of such Primary Insurance Policy
and, in this regard, to take such action as shall be necessary to permit
recovery under any Primary Insurance Policy respecting a defaulted Mortgage
Loan. Pursuant to Section 3.09(a), any amounts collected by the Master Servicer
under any Primary Insurance Policy shall be deposited in the Escrow Account,
subject to withdrawal pursuant to Section 3.09(b).

           SECTION 3.06. Rights of the Sponsor and the Trustee in Respect of the
Master Servicer. The Sponsor may, but is not obligated to, enforce the
obligations of the Master Servicer hereunder and may, but is not obligated to,
perform, or cause a designee to perform, any defaulted obligation of the Master
Servicer hereunder and in connection with any such defaulted obligation to
exercise the related rights of the Master Servicer hereunder; provided that the
Master Servicer shall not be relieved of any of its obligations hereunder by
virtue of such performance by the Sponsor or its designee. Neither the Trustee
nor the Sponsor shall have any responsibility or liability for any action or
failure to act by the Master Servicer nor shall the Trustee or the Sponsor be
obligated to supervise the performance of the Master Servicer hereunder or
otherwise.

           SECTION 3.07. Trustee to Act as Master Servicer. If the Master
Servicer shall for any reason no longer be the Master Servicer hereunder
(including by reason of an Event of Default), the Trustee shall thereupon
assume, if it so elects, or shall appoint a successor Master Servicer to assume,
all of the rights and obligations of the Master Servicer hereunder arising
thereafter (except that the Trustee shall not be (a) liable for losses of the
Master Servicer pursuant to Section 3.12 or any acts or omissions of the
predecessor Master Servicer hereunder, (b) obligated to make Advances if it is
prohibited from doing so by applicable law or (c) deemed to have made any
representations and warranties of the Master Servicer hereunder). Any such
assumption shall be subject to Section 7.02. If the Master Servicer shall for
any reason no longer be the Master Servicer (including by reason of any Event of
Default), the Trustee or the successor Master Servicer may elect to succeed to
any rights and obligations of the Master Servicer under each Servicing Agreement
or may terminate each Servicing Agreement. If it has elected to assume the
Servicing Agreement, the Trustee or the successor Master Servicer shall be
deemed to have assumed all of the Master Servicer's interest therein and to have
replaced the Master Servicer as a party to any Servicing Agreement entered into
by the Master Servicer as contemplated by Section 3.02 to the same extent as if
the Servicing Agreement had been assigned to the assuming party except that the




                                       37
<PAGE>   44

Master Servicer shall not be relieved of any liability or obligations under any
such Servicing Agreement.

           The Master Servicer shall, upon request of the Trustee, but at the
expense of the Master Servicer, deliver to the assuming party all documents and
records relating to each Servicing Agreement or substitute servicing agreement
and the Mortgage Loans then being serviced thereunder and an accounting of
amounts collected or held by it and otherwise use its best efforts to effect the
orderly and efficient transfer of such substitute Servicing Agreement to the
assuming party.

           SECTION 3.08. Collection of Mortgage Loan Payments; Collection
Account and Distribution Account.

           (a) Continuously from the date hereof until the principal and
interest on all Mortgage Loans are paid in full, the Master Servicer will
proceed diligently, in accordance with this Agreement, to collect all payments
due under each of the Mortgage Loans when the same shall become due and payable.
Further, the Master Servicer will in accordance with all applicable law and
Customary Servicing Procedures ascertain and estimate taxes, assessments, fire
and hazard insurance premiums, mortgage insurance premiums and all other charges
that, as provided in any Mortgage, will become due and payable to the end that
the installments payable by the Mortgagors will be sufficient to pay such
charges as and when they become due and payable. Consistent with the foregoing,
the Master Servicer may in its discretion (i) waive any late payment charge or
any prepayment charge or penalty interest in connection with the prepayment of a
Mortgage Loan and (ii) extend the due dates for payments due on a Mortgage Note
for a period not greater than 120 days; provided, however, that the Master
Servicer cannot extend the maturity of any such Mortgage Loan past the date on
which the final payment is due on the latest maturing Mortgage Loan as of the
Cut-Off Date. In the event of any such arrangement, the Master Servicer shall
make Monthly Advances on the related Mortgage Loan in accordance with the
provisions of Section 3.20 during the scheduled period in accordance with the
amortization schedule of such Mortgage Loan without modification thereof by
reason of such arrangements. 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 or otherwise or against any public or
governmental authority with respect to a taking or condemnation) if it
reasonably believes that enforcing the provision of the Mortgage or other
instrument pursuant to which such payment is required is prohibited by
applicable law.

           (b) The Master Servicer shall establish and maintain the Collection
Account. The Master Servicer shall deposit or cause to be deposited into the
Collection Account on a daily basis within one Business Day of receipt, except
as otherwise specifically provided herein, the following payments and
collections remitted by Servicers or received by it in respect of Mortgage Loans
subsequent to the Cut-Off Date (other than in respect of principal and interest
due on the Mortgage Loans on or before the Cut-Off Date) and the following
amounts required to be deposited hereunder:

                      (i) all payments on account of principal of the Mortgage
           Loans, including Principal Prepayments;


                                       38
<PAGE>   45

                      (ii) all payments on account of interest on the Mortgage
           Loans, net of the Master Servicing Fee;

                     (iii) (A) all Insurance Proceeds and Liquidation Proceeds,
           other than Insurance Proceeds to be (1) applied to the restoration or
           repair of the Mortgaged Property, (2) released to the Mortgagor in
           accordance with Customary Servicing Procedures or (3) required to be
           deposited to an Escrow Account pursuant to Section 3.09(a) and (B)
           any Insurance Proceeds released from an Escrow Account pursuant to
           Section 3.09(b)(iv);

                     (iv) any amount required to be deposited by the Master
           Servicer pursuant to Section 3.08(d) in connection with any losses on
           Permitted Investments with respect to the Collection Account;

                      (v) any amounts required to be deposited by the Master
           Servicer pursuant to Section 3.14;

                      (vi) all Purchase Prices and all Substitution Adjustment
           Amounts received by the Master Servicer;

                     (vii) all Monthly Advances made by the Master Servicer
           pursuant to Section 3.20 and any payments of Compensating Interest;
           and

                      (viii) any other amounts required to be deposited
           hereunder.

           The foregoing requirements for remittance by the Master Servicer
shall be exclusive, it being understood and agreed that, without limiting the
generality of the foregoing, payments in the nature of prepayment penalties,
late payment charges or assumption fees, if collected, need not be remitted by
the Master Servicer. In the event that the Master Servicer shall remit any
amount not required to be remitted, it may at any time withdraw or direct the
institution maintaining the Collection Account to withdraw such amount from the
Collection Account, any provision herein to the contrary notwithstanding. The
Master Servicer shall maintain adequate records with respect to all withdrawals
made pursuant to this Section 3.08. All funds required to be deposited in the
Collection Account shall be held in trust for the Certificateholders until
withdrawn in accordance with Section 3.11.

           (c) The Trustee shall establish and maintain, on behalf of the
Certificateholders, the Distribution Account. The Trustee shall, promptly upon
receipt, deposit in the Distribution Account and retain therein the following:

                      (i) the aggregate amount remitted by the Master Servicer
           to the Trustee pursuant to Section 3.11(a)(viii);

                      (ii) any amount paid by the Master Servicer pursuant to
           Section 3.08(d) in connection with any losses on Permitted
           Investments with respect to the Distribution Account; and


                                       39
<PAGE>   46

                      (iii) any other amounts deposited hereunder which are
           required to be deposited in the Distribution Account.

           If the Master Servicer shall remit any amount not required to be
remitted, it may at any time direct the Trustee to withdraw such amount from the
Distribution Account, any provision herein to the contrary notwithstanding. Such
direction may be accomplished by delivering an Officer's Certificate to the
Trustee which describes the amounts deposited in error in the Distribution
Account. All funds required to be deposited in the Distribution Account shall be
held by the Trustee in trust for the Certificateholders until disbursed in
accordance with this Agreement or withdrawn in accordance with Section 3.11. In
no event shall the Trustee incur liability for withdrawals from the Distribution
Account at the direction of the Master Servicer.

           (d) Each institution at which the Collection Account or the
Distribution Account is maintained shall invest the funds therein as directed in
writing by the Master Servicer (with respect to the Collection Account) or the
Trustee (with respect to the Distribution Account) in Permitted Investments,
which shall mature not later than (i) in the case of the Collection Account, the
Business Day next preceding the related Distribution Account Deposit Date
(except that if such Permitted Investment is an obligation of the institution
that maintains such account, then such Permitted Investment shall mature not
later than such Distribution Account Deposit Date) and (ii) in the case of the
Distribution Account, the Business Day next preceding the Distribution Date
(except that if such Permitted Investment is an obligation of the institution
that maintains such account, then such Permitted Investment shall mature not
later than such Distribution Date) and, in each case, shall not be sold or
disposed of prior to its maturity. All such Permitted Investments shall be made
in the name of the Trustee, for the benefit of the Certificateholders. All
income and gain (net of any losses) realized from any such investment of funds
on deposit in the Collection Account shall be for the benefit of the Master
Servicer as servicing compensation and shall be retained by it monthly as
provided herein. All income or gain (net of any losses) realized from any such
investment of funds on deposit in the Distribution Account shall be for the
benefit of the Trustee as additional compensation and shall be retained by it
monthly as provided herein. The amount of any losses realized in the Collection
Account or the Distribution Account incurred in any such account in respect of
any such investments shall promptly be deposited by the Master Servicer in the
Collection Account or by the Trustee in the Distribution Account, as applicable.

           (e) The Master Servicer shall give notice to the Trustee of any
proposed change of the location of the Collection Account not later than 30 days
and not more than 45 days prior to any change thereof. The Trustee shall give
notice to the Master Servicer, the Seller, each Rating Agency and the Sponsor of
any proposed change of the location of the Distribution Account not later than
30 days and not more than 45 days prior to any change thereof. The creation of
any Collection Account shall be evidenced by a certification substantially in
the form of Exhibit G hereto. A copy of such certification or letter agreement
shall be furnished to the Trustee.

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

           (a) To the extent required by the related Mortgage Note and not
violative of current law, the Master Servicer shall segregate and hold all funds
collected and received pursuant to each 



                                       40
<PAGE>   47

Mortgage Loan which constitute Escrow Payments in trust separate and apart from
any of its own funds and general assets and for such purpose shall establish and
maintain one or more escrow accounts (collectively, the "Escrow Account"),
titled "NationsBanc Mortgage Corporation, in trust for registered holders of
NationsBanc Montgomery Funding Corp. Mortgage Pass-Through Certificates, Series
1998-2 and various Mortgagors". The Escrow Account shall be established with a
commercial bank, a savings bank or a savings and loan association that meets the
guidelines set forth by FNMA or FHLMC as an eligible institution for escrow
accounts and which is a member of the Automated Clearing House. In any case, the
Escrow Account shall be insured by the FDIC to the fullest extent permitted by
law. The Master Servicer shall deposit in the Escrow Account on a daily basis,
and retain therein: (i) all Escrow Payments collected on account of the Mortgage
Loans, (ii) all amounts representing proceeds of any hazard insurance policy
which are to be applied to the restoration or repair of any Mortgaged Property
and (iii) all amounts representing proceeds of any Primary Insurance Policy.
Nothing herein shall require the Master Servicer to compel a Mortgagor to
establish an Escrow Account in violation of applicable law.

           (b) Withdrawals of amounts so collected from the Escrow Accounts may
be made by the Master Servicer only (i) to effect timely payment of taxes,
assessments, mortgage insurance premiums, fire and hazard insurance premiums,
condominium or PUD association dues, or comparable items constituting Escrow
Payments for the related Mortgage, (ii) to reimburse the Master Servicer out of
related Escrow Payments made with respect to a Mortgage Loan for any Servicing
Advance made by the Master Servicer pursuant to Section 3.09(c) with respect to
such Mortgage Loan, (iii) to refund to any Mortgagor any sums determined to be
overages, (iv) for transfer to the Collection Account upon default of a
Mortgagor or in accordance with the terms of the related Mortgage Loan and if
permitted by applicable law, (v) for application to restore or repair the
Mortgaged Property, (vi) to pay to the Mortgagor, to the extent required by law,
any interest paid on the funds deposited in the Escrow Account, (vii) to pay to
itself any interest earned on funds deposited in the Escrow Account (and not
required to be paid to the Mortgagor), (viii) to the extent permitted under the
terms of the related Mortgage Note and applicable law, to pay late fees with
respect to any Monthly Payment which is received after the applicable grace
period, (ix) to withdraw suspense payments that are deposited into the Escrow
Account, (x) to withdraw any amounts inadvertently deposited in the Escrow
Account or (xi) to clear and terminate the Escrow Account upon the termination
of this Agreement in accordance with Section 10.01. Any Escrow Account shall not
be a part of the Trust Fund.

           (c) With respect to each Mortgage Loan, the Master Servicer shall
maintain accurate records reflecting the status of taxes, assessments and other
charges which are or may become a lien upon the Mortgaged Property and the
status of Primary Insurance Policy premiums and fire and hazard insurance
coverage. The Master Servicer shall obtain, from time to time, all bills for the
payment of such charges (including renewal premiums) and shall effect payment
thereof prior to the applicable penalty or termination date and at a time
appropriate for securing maximum discounts allowable, employing for such purpose
deposits of the Mortgagor in the Escrow Account, if any, which shall have been
estimated and accumulated by the Master Servicer in amounts sufficient for such
purposes, as allowed under the terms of the Mortgage. To the extent that a
Mortgage does not provide for Escrow Payments, the Master Servicer shall
determine that any such payments are made by the Mortgagor. The Master Servicer
assumes full responsibility for the timely payment of all such bills and shall
effect timely payments of all such bills irrespective of each Mortgagor's
faithful 



                                       41
<PAGE>   48

performance in the payment of same or the making of the Escrow Payments. The
Master Servicer shall advance any such payments that are not timely paid, but
the Master Servicer shall be required so to advance only to the extent that such
Servicing Advances, in the good faith judgment of the Master Servicer, will be
recoverable by the Master Servicer out of Insurance Proceeds, Liquidation
Proceeds or otherwise.

           SECTION 3.10. Access to Certain Documentation and Information
Regarding the Mortgage Loans. The Master Servicer shall afford the Trustee
reasonable access to all records and documentation regarding the Mortgage Loans
and all accounts, insurance information and other matters relating to this
Agreement, such access being afforded without charge, but only upon reasonable
request and during normal business hours at the office designated by the Master
Servicer.

           Upon reasonable advance notice in writing, the Master Servicer will
provide to each Certificateholder which is a savings and loan association, bank
or insurance company certain reports and reasonable access to information and
documentation regarding the Mortgage Loans sufficient to permit such
Certificateholder to comply with applicable regulations of the OTS or other
regulatory authorities with respect to investment in the Certificates; provided
that the Master Servicer shall be entitled to be reimbursed by each such
Certificateholder for actual expenses incurred by the Master Servicer in
providing such reports and access.

           SECTION 3.11. Permitted Withdrawals from the Collection Account and
Distribution Account.

           (a) The Master Servicer may from time to time make withdrawals from
the Collection Account for the following purposes:

                     (i) to pay to the Master Servicer (to the extent not
           previously retained), the servicing compensation to which it is
           entitled pursuant to Section 3.17, and to pay to the Master Servicer,
           as additional master servicing compensation, earnings on or
           investment income with respect to funds in or credited to the
           Collection Account;

                     (ii) to reimburse the Master Servicer for unreimbursed
           Advances made by it, such right of reimbursement pursuant to this
           clause (ii) being limited to amounts received on the Mortgage Loan(s)
           in respect of which any such Advance was made;

                     (iii) to reimburse the Master Servicer for any
           Nonrecoverable Advance previously made, it being understood that, in
           the case of any such reimbursement, the Master Servicer's right
           thereto shall be prior to the rights of the Trust unless the Master
           Servicer is also the Seller and the Seller is required to purchase a
           Mortgage Loan pursuant to Section 2.02, 2.03 or 2.08, in which case
           the Master Servicer's right to such reimbursement shall be subsequent
           to the payment to the Trust of the Purchase Price and all other
           amounts required to be paid to the Trust with respect to such
           Mortgage Loan;

                      (iv) to reimburse the Master Servicer for Insured Expenses
           from the related Insurance Proceeds;



                                       42
<PAGE>   49

                     (v) to pay to the purchaser, with respect to each Mortgage
           Loan or REO Property that has been purchased pursuant to Section
           2.02, 2.03 or 2.08, all amounts received thereon after the date of
           such purchase;

                     (vi) to reimburse the Master Servicer or the Sponsor for
           expenses incurred by any of them and reimbursable pursuant to Section
           7.03;

                      (vii) to withdraw any amount deposited in the Collection
           Account and not required to be deposited therein;

                     (viii) on or prior to the Distribution Account Deposit
           Date, to withdraw an amount equal to the related Available Funds, the
           related Trustee Fee and any other amounts due to the Trustee under
           this Agreement for such Distribution Date, to the extent on deposit,
           and remit such amount to the Trustee for deposit in the Distribution
           Account; and

                     (ix) to clear and terminate the Collection Account upon
           termination of this Agreement pursuant to Section 10.01.

           The Master Servicer shall keep and maintain separate accounting, on a
Mortgage Loan by Mortgage Loan basis, for the purpose of justifying any
withdrawal from the Collection Account pursuant to clauses (i), (ii), (iv) and
(v). Prior to making any withdrawal from the Collection Account pursuant to
clause (iii), the Master Servicer shall deliver to the Trustee an Officer's
Certificate of a Servicing Officer indicating the amount of any previous Advance
determined by the Master Servicer to be a Nonrecoverable Advance and identifying
the related Mortgage Loan(s) and their respective portions of such
Nonrecoverable Advance.

           (b) The Trustee shall withdraw funds from the Distribution Account
for distributions to Certificateholders in the manner specified in this
Agreement. In addition, the Trustee may from time to time make withdrawals from
the Distribution Account for the following purposes:

                      (i) to pay to itself the Trustee Fee and any other amounts
           due to the Trustee under this Agreement for the related Distribution
           Date;

                     (ii) to pay to itself as additional compensation earnings
           on or investment income with respect to funds in the Distribution
           Account;

                     (iii) to withdraw and return to the Master Servicer any
           amount deposited in the Distribution Account and not required to be
           deposited therein; and

                     (iv) to clear and terminate the Distribution Account upon
           termination of the Agreement pursuant to Section 10.01.

           SECTION 3.12. Maintenance of Hazard Insurance. The Master Servicer
shall cause to be maintained for each Mortgage Loan fire and hazard insurance
with extended coverage customary in the area where the Mortgaged Property is
located in an amount which is at least equal 



                                       43
<PAGE>   50

to the lesser of (a) the full insurable value of the Mortgaged Property or (b)
the greater of (i) the outstanding principal balance owing on the Mortgage Loan
and (ii) an amount such that the proceeds of such insurance shall be sufficient
to avoid the application to the Mortgagor or loss payee of any coinsurance
clause under the policy. If the Mortgaged Property is in an area identified in
the Federal Register by the Federal Emergency Management Agency as having
special flood hazards (and such flood insurance has been made available) the
Master Servicer will cause to be maintained a flood insurance policy meeting the
requirements of the current guidelines of the Federal Insurance Administration
and the requirements of FNMA or FHLMC. The Master Servicer shall also maintain
on REO Property, fire and hazard insurance with extended coverage in an amount
which is at least equal to the maximum insurable value of the improvements which
are a part of such property, liability insurance and, to the extent required,
flood insurance in an amount required above. Any amounts collected by the Master
Servicer under any such policies (other than amounts to be deposited in the
Escrow Account and applied to the restoration or repair of the property subject
to the related Mortgage or property acquired in liquidation of the Mortgage
Loan, or to be released to the Mortgagor in accordance with Customary Servicing
Procedures) shall be deposited in the Collection Account, subject to withdrawal
pursuant to Section 3.11(a). It is understood and agreed that no earthquake or
other additional insurance need be required by the Master Servicer of any
Mortgagor or maintained on REO Property, other than pursuant to such applicable
laws and regulations as shall at any time be in force and as shall require such
additional insurance. All policies required hereunder shall be endorsed with
standard mortgagee clauses with loss payable to the Master Servicer, and shall
provide for at least 30 days prior written notice of any cancellation, reduction
in amount or material change in coverage to the Master Servicer.

           The hazard insurance policies for each Mortgage Loan secured by a
unit in a condominium development or planned unit development shall be
maintained with respect to such Mortgage Loan and the related development in a
manner which is consistent with FNMA requirements.

           SECTION 3.13. Enforcement of Due-On-Sale Clauses; Assumption
Agreements.

           (a) Except as otherwise provided in this Section 3.13, when any
Mortgaged Property subject to a Mortgage has been conveyed by the Mortgagor, the
Master Servicer shall use reasonable efforts, to the extent that it has actual
knowledge of such conveyance, to enforce any due-on-sale clause contained in any
Mortgage Note or Mortgage, to the extent permitted under applicable law and
governmental regulations, but only to the extent that such enforcement will not
adversely affect or jeopardize coverage under any Required Insurance Policy.
Notwithstanding the foregoing, the Master Servicer is not required to exercise
such rights with respect to a Mortgage Loan if the Person to whom the related
Mortgaged Property has been conveyed or is proposed to be conveyed satisfies the
terms and conditions contained in the Mortgage Note and Mortgage related thereto
and the consent of the mortgagee under such Mortgage Note or Mortgage is not
otherwise required under such Mortgage Note or Mortgage as a condition to such
transfer. If (i) the Master Servicer is prohibited by law from enforcing any
such due-on-sale clause, (ii) coverage under any Required Insurance Policy would
be adversely affected, (iii) the Mortgage Note does not include a due-on-sale
clause or (iv) nonenforcement is otherwise permitted hereunder, the Master
Servicer is authorized, subject to Section 3.13(b), to take or enter into an
assumption and modification agreement from or with the Person to whom such
Mortgaged Property has been or is about to be conveyed, pursuant to which such
Person becomes liable under the Mortgage Note and, unless 



                                       44
<PAGE>   51

prohibited by applicable state law, the Mortgagor remains liable thereon;
provided that the Mortgage Loan shall continue to be covered (if so covered
before the Master Servicer enters such agreement) by the applicable Required
Insurance Policies. The Master Servicer, subject to Section 3.13(b), is also
authorized with the prior approval of the insurers under any Required Insurance
Policies 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 Mortgagor and becomes liable under the Mortgage Note.
Notwithstanding the foregoing, the Master Servicer shall not be deemed to be in
default under this Section 3.13 by reason of any transfer or assumption which
the Master Servicer reasonably believes it is restricted by law from preventing,
for any reason whatsoever.

           (b) Subject to the Master Servicer's duty to enforce any due-on-sale
clause to the extent set forth in Section 3.13(a), in any case in which a
Mortgaged Property has been conveyed to a Person by a Mortgagor, and such Person
is to enter into an assumption agreement or modification agreement or supplement
to the Mortgage Note or Mortgage that requires the signature of the Trustee, or
if an instrument of release signed by the Trustee is required releasing the
Mortgagor from liability on the Mortgage Loan, the Master Servicer shall prepare
and deliver or cause to be prepared and delivered to the Trustee for signature
and shall direct, in writing, the Trustee to execute the assumption agreement
with the Person to whom the Mortgaged Property is to be conveyed and such
modification agreement or supplement to the Mortgage Note or Mortgage or other
instruments as are reasonable or necessary to carry out the terms of the
Mortgage Note or Mortgage or otherwise to comply with any applicable laws
regarding assumptions or the transfer of the Mortgaged Property to such Person.
In no event shall the Trustee incur liability for executing any document under
this Section 3.13 at the direction of the Master Servicer. In connection with
any such assumption, no material term of the Mortgage Note may be changed. In
addition, the substitute Mortgagor and the Mortgaged Property must be acceptable
to the Master Servicer in accordance with its underwriting standards as then in
effect. Together with each such substitution, assumption or other agreement or
instrument delivered to the Trustee for execution by it, the Master Servicer
shall deliver an Officer's Certificate signed by a Servicing Officer stating
that the requirements of this subsection have been met. The Master Servicer
shall notify the Trustee that any such substitution or assumption agreement has
been completed by forwarding to the Trustee (or at the direction of the Trustee,
the Custodian) the original of such substitution or assumption agreement, which
in the case of the original 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. Any
fee collected by the Master Servicer for entering into an assumption or
substitution of liability agreement may be retained by the Master Servicer as
additional master servicing compensation. Notwithstanding the foregoing, to the
extent permissible under applicable law and at the request of the Master
Servicer, the Trustee shall execute and deliver to the Master Servicer any
powers of attorney and other documents prepared by the Master Servicer that are
reasonably necessary or appropriate to enable the Master Servicer to execute any
assumption agreement or modification agreement required to be executed by the
Trustee under this Section 3.13.

           SECTION 3.14. Realization Upon Defaulted Mortgage Loans; REO
Property. The Master Servicer shall use reasonable efforts to foreclose upon or
otherwise comparably convert the ownership of Mortgaged Properties securing such
of the Mortgage Loans as come into and continue 



                                       45
<PAGE>   52

in default and as to which no satisfactory arrangements can be made for
collection of delinquent payments. In connection with such foreclosure or other
conversion, the Master Servicer shall follow Customary Servicing Procedures and
shall meet the requirements of the insurer under any Required Insurance Policy.
Notwithstanding the foregoing, the Master Servicer shall not be required to
expend its own funds in connection with any foreclosure or towards the
restoration of any Mortgaged Property unless it shall determine (a) that such
restoration and/or foreclosure will increase the proceeds of liquidation of the
Mortgage Loan after reimbursement to itself of such expenses and (b) that such
expenses will be recoverable to it through proceeds of the liquidation of the
Mortgage Loan (respecting which it shall have priority for purposes of
withdrawals from the Collection Account). Any such expenditures shall constitute
Servicing Advances for purposes of this Agreement.

           The decision of the Master Servicer to foreclose on a defaulted
Mortgage Loan shall be subject to a determination by the Master Servicer that
the proceeds of such foreclosure would exceed the costs and expenses of bringing
such a proceeding.

           With respect to any REO Property, the deed or certificate of sale
shall be taken in the name of the Trustee for the benefit of the
Certificateholders, or its nominee, on behalf of the Certificateholders. The
Trustee's name shall be placed on the title to such REO Property solely as the
Trustee hereunder and not in its individual capacity. The Master Servicer shall
ensure that the title to such REO Property references the Agreement and the
Trustee's capacity hereunder. Pursuant to its efforts to sell such REO Property,
the Master Servicer shall either itself or through an agent selected by the
Master Servicer manage, conserve, protect and operate such REO Property in the
same manner that it manages, conserves, protects and operates other foreclosed
property for its own account and in the same manner that similar property in the
same locality as the REO Property is managed. Incident to its conservation and
protection of the interests of the Certificateholders, the Master Servicer may
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. The Master Servicer shall prepare for and deliver to the Trustee a
statement with respect to each REO Property that has been rented, if any,
showing the aggregate rental income received and all expenses incurred in
connection with the management and maintenance of such REO Property at such
times as is necessary to enable the Trustee to comply with the reporting
requirements of the REMIC Provisions; provided, however, that the Master
Servicer shall have no duty to rent any REO Property on behalf of the Trust. The
net monthly rental income, if any, from such REO Property shall be deposited in
the Collection Account no later than the close of business on each Determination
Date. The Master Servicer shall perform the tax reporting and withholding
required by Sections 1445 and 6050J of the Code with respect to foreclosures and
abandonments, the tax reporting required by Section 6050H of the Code with
respect to the receipt of mortgage interest from individuals and, if required by
Section 6050P of the Code with respect to the cancellation of indebtedness by
certain financial entities, by preparing such tax and information returns as may
be required, in the form required. The Master Servicer shall deliver copies of
such reports to the Trustee.

           If the Trust acquires any Mortgaged Property as described above or
otherwise in connection with a default or a default which is reasonably
foreseeable on a Mortgage Loan, the Master Servicer shall dispose of such
Mortgaged Property prior to the end of the third calendar year following the




                                       46
<PAGE>   53

year of its acquisition by the Trust (such period, the "REO Disposition Period")
unless (a) the Trustee shall have been supplied by the Master Servicer with an
Opinion of Counsel to the effect that the holding by the Trust of such Mortgaged
Property subsequent to the REO Disposition Period will not result in the
imposition of taxes on "prohibited transactions" on the REMIC (as defined in
Section 860F of the Code) or cause the REMIC to fail to qualify as a REMIC at
any time that any Certificates are outstanding, or (b) the Trustee (at the
Master Servicer's expense) or the Master Servicer shall have applied for, prior
to the expiration of the REO Disposition Period, an extension of the REO
Disposition Period in the manner contemplated by Section 856(e)(3) of the Code.
If such an Opinion of Counsel is provided or such an exemption is obtained, the
Trust may continue to hold such Mortgaged Property (subject to any conditions
contained in such Opinion of Counsel) for the applicable period. Notwithstanding
any other provision of this Agreement, no Mortgaged Property acquired by the
Trust shall be rented (or allowed to continue to be rented) or otherwise used
for the production of income by or on behalf of the Trust in such a manner or
pursuant to any terms that would (i) cause such Mortgaged Property to fail to
qualify as "foreclosure property" within the meaning of Section 860G(a)(8) of
the Code or (ii) subject the REMIC to the imposition of any federal, state or
local income taxes on the income earned from such Mortgaged Property under
Section 860G(c) of the Code or otherwise, unless the Master Servicer has agreed
to indemnify and hold harmless the Trust with respect to the imposition of any
such taxes. The Master Servicer shall identify to the Trustee any Mortgaged
Property held by the Trust for 30 months for which no plans to dispose of such
Mortgaged Property by the Master Servicer have been made. After delivery of such
identification, the Master Servicer shall proceed to dispose of any such
Mortgaged Property by holding a commercially reasonable auction for such
property.

           The income earned from the management of any REO Properties, net of
reimbursement to the Master Servicer for expenses incurred (including any
property or other taxes) in connection with such management and net of
unreimbursed Master Servicing Fees, Monthly Advances and Servicing Advances,
shall be applied to the payment of principal of and interest on the related
defaulted Mortgage Loans (solely for the purposes of allocating principal and
interest, interest shall be treated as accruing as though such Mortgage Loans
were still current) and all such income shall be deemed, for all purposes in
this Agreement, to be payments on account of principal and interest on the
related Mortgage Notes and shall be deposited into the Collection Account. To
the extent the net income received during any calendar month is in excess of the
amount attributable to amortizing principal and accrued interest at the related
Mortgage Rate on the related Mortgage Loan for such calendar month, such excess
shall be considered to be a partial prepayment of principal of the related
Mortgage Loan.

           The proceeds from any liquidation of a Mortgage Loan, as well as any
income from an REO Property, will be applied in the following order of priority:
first, to reimburse the Master Servicer for any related unreimbursed Servicing
Advances and Master Servicing Fees; second, to reimburse the Master Servicer for
any unreimbursed Monthly Advances and to reimburse the Collection Account for
any Nonrecoverable Advances (or portions thereof) that were previously withdrawn
by the Master Servicer pursuant to Section 3.11(a)(iii) that related to such
Mortgage Loan; third, to accrued and unpaid interest (to the extent no Monthly
Advance has been made for such amount or any such Monthly Advance has been
reimbursed) on the Mortgage Loan or related REO Property, at the Mortgage Rate
to the Due Date occurring in the month in which such amounts are required to be
distributed; and fourth, as a recovery of principal of the Mortgage Loan. Excess
Proceeds, if any, 



                                       47
<PAGE>   54

from the liquidation of a Liquidated Mortgage Loan will be retained by the
Master Servicer as additional servicing compensation pursuant to Section 3.17.

           SECTION 3.15. 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 will be escrowed in a manner customary
for such purposes, the Master Servicer will immediately notify the Trustee (or,
at the direction of the Trustee, the Custodian) by delivering, or causing to be
delivered, two copies (one of which will be returned to the Master Servicer with
the Mortgage File) of a Request for Release (which may be delivered in an
electronic format acceptable to the Trustee and the Master Servicer). Upon
receipt of such request, the Trustee or the Custodian, as applicable, shall
within seven Business Days release the related Mortgage File to the Master
Servicer. The Trustee shall at the Master Servicer's direction execute and
deliver to the Master Servicer the request for reconveyance, deed of
reconveyance or release or satisfaction of mortgage or such instrument releasing
the lien of the Mortgage, in each case provided by the Master Servicer, together
with the Mortgage Note with written evidence of cancellation thereon. Expenses
incurred in connection with any instrument of satisfaction or deed of
reconveyance shall be chargeable to the related Mortgagor. From time to time and
as shall be appropriate for the servicing or foreclosure of any Mortgage Loan,
including for such purpose collection under any policy of flood insurance, any
fidelity bond or errors or omissions policy, or for the purposes of effecting a
partial release of any Mortgaged Property from the lien of the Mortgage or the
making of any corrections to the Mortgage Note or the Mortgage or any of the
other documents included in the Mortgage File, the Trustee or the Custodian, as
applicable, shall, upon delivery to the Trustee (or, at the direction of the
Trustee, the Custodian) of a Request for Release signed by a Servicing Officer,
release the Mortgage File within seven Business Days to the Master Servicer.
Subject to the further limitations set forth below, the Master Servicer shall
cause the Mortgage File so released to be returned to the Trustee or the
Custodian, as applicable, when the need therefor by the Master Servicer no
longer exists, unless the Mortgage Loan is liquidated and the proceeds thereof
are deposited in the Collection Account, in which case the Master Servicer shall
deliver to the Trustee or the Custodian, as applicable a Request for Release,
signed by a Servicing Officer.

           The Trustee shall execute and deliver to the Master Servicer any
powers of attorney and other documents prepared by the Master Servicer that are
reasonably necessary or appropriate to enable the Master Servicer to carry out
its servicing and administrative duties under this Agreement, upon the request
of the Master Servicer. In addition, upon prepayment in full of any Mortgage
Loan or the receipt of notice that funds for such purpose have been placed in
escrow, the Master Servicer is authorized to give, as attorney-in-fact for the
Trustee and the mortgagee under the Mortgage, an instrument of satisfaction (or
Assignment of Mortgage without recourse) regarding the Mortgaged Property
relating to such Mortgage Loan, which instrument of satisfaction or Assignment
of Mortgage, as the case may be, shall be delivered to the Person entitled
thereto against receipt of the prepayment in full. In lieu of executing such
satisfaction or Assignment of Mortgage, or if another document is required to be
executed by the Trustee, the Master Servicer may deliver or cause to be
delivered to the Trustee, for signature, as appropriate, any court pleadings,
requests for trustee's sale or other documents necessary to effectuate such
foreclosure or any legal action brought to obtain judgment against the Mortgagor
on the Mortgage Note or the Mortgage or to obtain a deficiency judgment or to
enforce any other remedies or rights provided by the Mortgage Note or the
Mortgage or otherwise available at law or in equity.


                                       48
<PAGE>   55

           SECTION 3.16. Documents, Records and Funds in Possession of the
Master Servicer to be Held for the Trustee . The Master Servicer shall transmit
to the Trustee or, at the direction of the Trustee, the Custodian as required by
this Agreement all documents and instruments in respect of a Mortgage Loan
coming into the possession of the Master Servicer from time to time and shall
account fully to the Trustee for any funds received by the Master Servicer or
which otherwise are collected by the Master Servicer as Liquidation Proceeds or
Insurance Proceeds in respect of any Mortgage Loan. The documents constituting
the Servicing File shall be held by the Master Servicer as custodian and bailee
for the Trustee. All Mortgage Files and funds collected or held by, or under the
control of, the Master Servicer in respect of any Mortgage Loans, whether from
the collection of principal and interest payments or from Liquidation Proceeds,
including but not limited to, any funds on deposit in the Collection Account,
shall be held by the Master Servicer for and on behalf of the Trustee and shall
be and remain the sole and exclusive property of the Trustee, subject to the
applicable provisions of this Agreement. The Master Servicer also agrees that it
shall not knowingly create, incur or subject any Mortgage File or any funds that
are deposited in the Collection Account, Distribution Account or any Escrow
Account, or any funds that otherwise are or may become due or payable to the
Trustee for the benefit of the Certificateholders, to any claim, lien, security
interest, judgment, levy, writ of attachment or other encumbrance created by the
Master Servicer, or assert by legal action or otherwise any claim or right of
setoff against any Mortgage File or any funds collected on, or in connection
with, a Mortgage Loan, except, however, that the Master Servicer shall be
entitled to set off against and deduct from any such funds any amounts that are
properly due and payable to the Master Servicer under this Agreement.

           SECTION 3.17. Servicing Compensation. The Master Servicer shall be
entitled out of each payment of interest on a Mortgage Loan (or portion thereof)
included in the Trust Fund to retain or withdraw from the Collection Account an
amount equal to the Master Servicing Fee for such Distribution Date.

           Additional master servicing compensation in the form of Excess
Proceeds, prepayment penalties, assumption fees, late payment charges and all
income and gain net of any losses realized from Permitted Investments and all
other customary and ancillary income and fees shall be retained by the Master
Servicer to the extent not required to be deposited in the Collection Account
pursuant to Section 3.08(b). The Master Servicer shall be required to pay all
expenses incurred by it in connection with its servicing activities hereunder
and shall not be entitled to reimbursement therefor except as specifically
provided in this Agreement.

           Notwithstanding the foregoing, with respect to the payment of the
Master Servicing Fee on any Distribution Date, the aggregate Master Servicing
Fee for such Distribution Date shall be reduced (but not below zero) by an
amount equal to the lesser of (a) such Prepayment Interest Shortfall for such
Distribution Date and (b) one-twelfth of 0.25% of the Pool Stated Principal
Balance for such Distribution Date (any such reduction, "Compensating
Interest").

           SECTION 3.18. Annual Statement as to Compliance. The Master Servicer
shall deliver to the Trustee and each Rating Agency on or before 75 days after
the end of the Master Servicer's fiscal year, commencing with its 1998 fiscal
year, an Officer's Certificate stating, as to the signer thereof, that (a) a
review of the activities of the Master Servicer during the preceding 



                                       49
<PAGE>   56

calendar year and of the performance of the Master Servicer under this Agreement
has been made under such officer's supervision, and (b) to the best of such
officer's knowledge, based on such review, the Master Servicer has fulfilled all
its obligations under this Agreement throughout 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.

           SECTION 3.19. Annual Independent Public Accountants' Servicing
Statement; Financial Statements. On or before 75 days after the end of the
Master Servicer's fiscal year, commencing with its 1998 fiscal year, the Master
Servicer, at its expense, shall cause a firm of independent public accountants
(who may also render other services to the Master Servicer, the Seller or any
affiliate thereof) which is a member of the American Institute of Certified
Public Accountants to furnish a statement to the Trustee to the effect that such
firm has with respect to the Master Servicer's overall servicing operations,
examined such operations in accordance with the requirements of the Uniform
Single Attestation Program for Mortgage Bankers, stating such firm's conclusions
relating thereto.

           SECTION 3.20. Advances. The Master Servicer shall determine on or
before each Master Servicer Advance Date whether it is required to make a
Monthly Advance pursuant to the definition thereof. If the Master Servicer
determines it is required to make a Monthly Advance, it shall, on or before the
Master Servicer Advance Date, either (a) deposit into the Collection Account an
amount equal to the Advance and/or (b) make an appropriate entry in its records
relating to the Collection Account that any Amount Held for Future Distribution
has been used by the Master Servicer in discharge of its obligation to make any
such Monthly Advance. Any funds so applied shall be replaced by the Master
Servicer by deposit in the Collection Account no later than the close of
business on the Business Day preceding the next Master Servicer Advance Date.
The Master Servicer shall be entitled to be reimbursed from the Collection
Account for all Advances of its own funds made pursuant to this Section 3.20 as
provided in Section 3.11(a). The obligation to make Monthly Advances with
respect to any Mortgage Loan shall continue until the ultimate disposition of
the REO Property or Mortgaged Property relating to such Mortgage Loan. The
Master Servicer shall inform the Trustee of the amount of the Monthly Advance to
be made on each Master Servicer Advance Date no later than the related
Distribution Account Deposit Date.

           The Master Servicer shall deliver to the Trustee on the related
Master Servicer Advance Date an Officer's Certificate of a Servicing Officer
indicating the amount of any proposed Monthly Advance determined by the Master
Servicer to be a Nonrecoverable Advance. Notwithstanding anything to the
contrary, the Master Servicer shall not be required to make any Monthly Advance
or Servicing Advance that would be a Nonrecoverable Advance.

           SECTION 3.21. Modifications, Waivers, Amendments and Consents.

           (a) Subject to this Section 3.21, the Master Servicer may agree to
any modification, waiver, forbearance, or amendment of any term of any Mortgage
Loan without the consent of the Trustee or any Certificateholder. All
modifications, waivers, forbearances or amendments of any Mortgage Loan shall be
in writing and shall be consistent with Customary Servicing Procedures.


                                       50
<PAGE>   57

           (b) The Master Servicer shall not agree to enter into, and shall not
enter into, any modification, waiver (other than a waiver referred to in Section
3.13, which waiver, if any, shall be governed by Section 3.13), forbearance or
amendment of any term of any Mortgage Loan if such modification, waiver,
forbearance, or amendment would:

                      (i) affect the amount or timing of any related payment of
           principal, interest or other amount payable thereunder; or

                      (ii) in the Master Servicer's judgment, materially impair
           the security for such Mortgage Loan or reduce the likelihood of
           timely payment of amounts due thereon;

unless, in either case, (A) such Mortgage Loan is 90 days or more past due or
(B) the Master Servicer delivers to the Trustee an Opinion of Counsel to the
effect that such modification, waiver, forbearance or amendment would not affect
the Trust Fund's REMIC status and, in either case, such modification, waiver,
forbearance or amendment is reasonably likely to produce a greater recovery with
respect to such Mortgage Loan than would liquidation. Subject to Customary
Servicing Procedures, the Master Servicer may permit a forbearance for a
Mortgage Loan which in the Master Servicer's judgment is subject to imminent
default.

           (c) Any payment of interest, which is deferred pursuant to any
modification, waiver, forbearance or amendment permitted hereunder, shall not,
for purposes hereof, including, without limitation, calculating monthly
distributions to Certificateholders, be added to the unpaid principal balance of
the related Mortgage Loan, notwithstanding that the terms of such Mortgage Loan
or such modification, waiver or amendment so permit.

           (d) The Master Servicer may, as a condition to granting any request
by a Mortgagor for consent, modification, waiver, forbearance or amendment, the
granting of which is within the Master Servicer's discretion pursuant to the
Mortgage Loan and is permitted by the terms of this Agreement, require that such
Mortgagor pay to the Master Servicer, as additional servicing compensation, a
reasonable or customary fee for the additional services performed in connection
with such request, together with any related costs and expenses incurred by the
Master Servicer, which amount shall be retained by the Master Servicer as
additional servicing compensation.

           (e) The Master Servicer shall notify the Trustee, in writing, of any
modification, waiver, forbearance or amendment of any term of any Mortgage Loan
and the date thereof, and shall deliver to the Trustee (or, at the direction of
the Trustee, the Custodian) for deposit in the related Mortgage File, an
original counterpart of the agreement relating to such modification, waiver,
forbearance or amendment, promptly (and in any event within ten Business Days)
following the execution thereof; provided, however, that if any such
modification, waiver, forbearance or amendment is required by applicable law to
be recorded, the Master Servicer (i) shall deliver to the Trustee a copy thereof
and (ii) shall deliver to the Trustee such document, with evidence of
notification upon receipt thereof from the public recording office.

           SECTION 3.22. Reports to the Securities and Exchange Commission. The
Trustee shall, on behalf of the Trust, cause to be filed with the Securities and
Exchange Commission any periodic reports required to be filed under the
provisions of the Securities Exchange Act of 1934, as 



                                       51
<PAGE>   58

amended, and the rules and regulations of the Securities and Exchange Commission
thereunder, for so long as any Certificates registered under the 1933 Act are
outstanding. Upon the request of the Trustee, each of the Master Servicer and
the Sponsor shall cooperate with the Trustee in the preparation of any such
report and shall provide to the Trustee in a timely manner all such information
or documentation as the Trustee may reasonably request in connection with the
performance of its duties and obligations under this Section.


                                   ARTICLE IV
                          MASTER SERVICER'S CERTIFICATE

           SECTION 4.01. Master Servicer's Certificate. Each month, not later
than 12:00 noon Eastern time on the Business Day following each Determination
Date, the Master Servicer shall deliver to the Trustee, a Master Servicer's
Certificate (in substance and format mutually acceptable to the Master Servicer
and the Trustee) certified by a Servicing Officer. The Trustee may conclusively
rely upon the information contained in a Master Servicer's Certificate for all
purposes hereunder and shall have no duty to verify or re-compute any of the
information contained therein.

           Such statement shall be provided by the Trustee to any Holder of a
Certificate upon request and shall also, to the extent available, include
information regarding delinquencies on Mortgage Loans, indicating the number and
aggregate principal amount of Mortgage Loans which are either one, two, three or
more than three months delinquent and the book value of any REO Property.


                                    ARTICLE V

                           PAYMENTS AND STATEMENTS TO
                    CERTIFICATEHOLDERS; REMIC ADMINISTRATION

           SECTION 5.01. Distributions. On each Distribution Date, the Trustee
shall distribute out of the Distribution Account to each Certificateholder of
record on the related Record Date (other than as provided in Section 10.01
respecting the final distribution) (a) by check mailed to such Certificateholder
entitled to receive a distribution on such Distribution Date at the address
appearing in the Certificate Register, or (b) upon written request by the Holder
of a Regular Certificate (in the event such Certificateholder owns of record
100% of a Class of Certificates or holds Certificates of any Class having
denominations aggregating $1,000,000 or more), by wire transfer or by such other
means of payment as such Certificateholder and the Trustee shall agree upon,
such Certificateholder's Percentage Interest in, the amount to which the related
Class of Certificates is entitled in accordance with the priorities set forth
below in Section 5.02.

           None of the Holders of any Class of Certificates, the Sponsor, the
Master Servicer or the Trustee shall in any way be responsible or liable to
Holders of any Class of Certificates in respect of amounts properly previously
distributed on any such Class.


                                       52
<PAGE>   59

           Amounts distributed with respect to any Class of Certificates shall
be applied first to the distribution of interest thereon and then to principal
thereon.

           SECTION 5.02. Priorities of Distribution.

           (a) On each Distribution Date, the Trustee shall withdraw from the
Distribution Account (1) the amounts payable to the Trustee pursuant to Sections
3.11(b)(i) and 3.11(b)(ii) and shall pay such funds to itself, and (2) the
Available Funds, in an amount as specified in written notice received by the
Trustee from the Master Servicer no later than the related Determination Date,
and shall apply such funds to distributions on the Certificates in the following
order of priority and to the extent of Available Funds:

                      (i) to each Class of Senior Certificates (other than the
           Class A-PO Certificates), an amount allocable to interest equal to
           the Interest Distribution Amount for such Class, any shortfall being
           allocated among such Classes in proportion to the amount of the
           Interest Distribution Amount that would have been distributed in the
           absence of such shortfall;

                      (ii) to each Class of Senior Certificates, concurrently as
           follows:

                                 (A) to the Class A-PO Certificates, up to the
                      amount of the PO Principal Amount, until the outstanding
                      Class Certificate Balance thereof has been reduced to
                      zero; and

                                 (B) on each Distribution Date prior to the

Distribution Date, (i) the aggregate of the Class Certificate Balances
immediately prior to such Distribution Date of all Classes of Subordinate
Certificates which have a higher numerical Class designation than such Class,
divided by (ii) the aggregate Class Certificate Balance of all the Certificates
immediately prior to such Distribution Date (the "Credit Support Percentage") is
less than the Original Credit Support Percentage for such Class, no distribution
of principal will be made to any Classes junior to such Class (the "Restricted
Classes") and the amount otherwise distributable to the Restricted Classes in
respect to principal shall be distributed to the Classes of Subordinate
Certificates that are not Restricted Classes, pro rata, based on their
respective Class Certificate Balances immediately prior to such Distribution
Date, and shall be distributed in the order provided in Section 5.02(a)(iv).

           SECTION 5.03. Allocation of Losses.

           (a) On or prior to each Determination Date, the Master Servicer shall

Valuation, a Debt Service Reduction, a Fraud Loss or a Special Hazard Loss, (2)
of the amount of such loss or Deficient Valuation, or of the terms of such Debt
Service Reduction and (3) of the total amount of Realized Losses. Based on such
information, the Trustee shall determine the total amount of Realized Losses,
including Excess Losses, with respect to the related Distribution Date.

           Realized Losses with respect to any Distribution Date shall be
allocated as follows:


                                       56

                     (i) the applicable PO Percentage of any Realized Loss with
           respect to a Discount Mortgage Loan, including any Excess Loss, shall
           be allocated to the Class A-PO Certificates until the Class
           Certificate Balance thereof is reduced to zero; and

                     (ii) (1) the applicable Non-PO Percentage of any Realized
                     Loss (other than an Excess Loss) shall be allocated first
                     to the Subordinate Certificates in reverse order of their
                     respective numerical Class designations (beginning with the
                     Class of Subordinate Certificates then outstanding with the
                     highest numerical Class designation) until the respective
                     Class Certificate Balance of each such Class is reduced to
                     zero, and second to the Senior Certificates (other than the
                     Notional Amount Certificates and the Class A-PO
                     Certificates), pro rata, on the basis of their respective
                     Class Certificate Balances immediately prior to the related
                     Distribution Date until the Class Certificate Balances
                     thereof have been reduced to zero; and

                          (2) the applicable Non-PO Percentage of any
                     Excess Losses shall be allocated to the Senior Certificates
                     (other than the Notional Amount Certificates and the Class
                     A-PO Certificates) and the Subordinate Certificates then
                     outstanding, pro rata, on the basis of their respective
                     Class Certificate Balances.

           (b) The Class Certificate Balance of the Class of Subordinate
Certificates then outstanding with the highest numerical Class designation shall
be reduced on each Distribution Date by the amount, if any, by which the
aggregate of the Class Certificate Balances of all outstanding Classes of
Certificates (after giving effect to the distribution of principal and the
allocation of Realized Losses and Class A-PO Deferred Amounts on such
Distribution Date) exceeds the Pool Stated Principal Balance for the following
Distribution Date.

           (c) Any Realized Loss allocated to a Class of Certificates or any
reduction in the Class Certificate Balance of a Class of Certificates pursuant
to Section 5.03(b) above shall be allocated among the Certificates of such Class
in proportion to their respective Percentage Interests.

           (d) Any allocation of Realized Losses to a Certificate or any
reduction in the Certificate Balance of a Certificate, pursuant to Section
5.03(b) above shall be accomplished by reducing the Certificate Balance thereof
prior to the distributions made on the related Distribution Date in accordance
with the definition of "Certificate Balance."

           SECTION 5.04. Statements to Certificateholders.

           (a) Prior to the Distribution Date in each month, based upon the

information set forth in Section 5.04(a).

           In the case of information furnished pursuant to clauses (i), (ii)
and (ix) of Section 5.04(a), the amounts shall be expressed as a dollar amount
or Notional Amount, as the case may be, per Certificate with a $1,000
denomination.

           On each Distribution Date, the Trustee shall prepare and furnish to
each Financial Market Publisher, in electronic or such other format and media
mutually agreed upon by the Trustee, the Financial Market Publisher and the
Sponsor, the information contained in the statement described in Section 5.04(a)
for such Distribution Date.

           Within a reasonable period of time after the end of each calendar
year, the Trustee shall furnish to each Person who at any time during the
calendar year was the Holder of a Certificate, if requested in writing by such
Person, a statement containing the information set forth in clauses (i), (ii)
and (vii) of Section 5.04(a), in each case 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 in force.

           The Trustee shall deliver to the Holders of Certificates any reports
or information the Trustee is required by this Agreement or the Code, Treasury
Regulations or REMIC Provisions to deliver to the Holders of Certificates, and
the Trustee shall prepare and provide to the Certificateholders (by mail,
telephone, or publication as may be permitted by applicable Treasury
Regulations) such other reasonable information as the Trustee deems necessary or
appropriate or is required by the Code, Treasury Regulations, and the REMIC
Provisions including, but not limited to, (i) information to be reported to the
Holders of the Residual Certificates for quarterly notices on Schedule Q (Form
1066) (which information shall be forwarded to the Holders of the Residual
Certificates by the Trustee), (ii) information to be provided to the Holders of
Certificates with respect to amounts which should be included as interest and
original issue discount in such Holders' gross income and (iii) information to
be provided to all Holders of Certificates setting forth the percentage of the
REMIC's assets, determined in accordance with Treasury Regulations using a
convention, not inconsistent with Treasury Regulations, selected by the Trustee
in its absolute discretion, that constitute real estate assets under Section 856
of the Code, and assets described in Section 7701(a)(19)(C) of the Code;
provided, however, that in setting forth the percentage of such assets of the
REMIC, nothing contained in this Agreement, including without limitation Section
7.03 hereof, shall be interpreted to require the Trustee periodically to
appraise the fair market values of the assets of the Trust Fund or to indemnify
the Trust Fund or any Certificateholders from any adverse federal, state or
local tax consequences associated with a change subsequently required to 



                                       59
<PAGE>   66

be made in the Sponsor's initial good faith determinations of such fair market
values (if subsequent determinations are required pursuant to the REMIC
Provisions) made from time to time.

           SECTION 5.05. Tax Returns and Reports to Certificateholders.

           (a) For federal income tax purposes, the REMIC shall have a calendar
year taxable year and shall maintain its books on the accrual method of
accounting.

           (b) The Trustee shall prepare or cause to be prepared and shall file
or cause to be filed with the Internal Revenue Service and applicable state or
local tax authorities income tax information returns for each taxable year with
respect to the REMIC containing such information at the times and in the manner
as may be required by the Code or state or local tax laws, regulations, or
rules, and shall furnish or cause to be furnished to the REMIC and the
Certificateholders the schedules, statements or information at such times and in
such manner as may be required thereby. Within 30 days of the Closing Date, the
Trustee shall furnish or cause to be furnished to the Internal Revenue Service,
on Form 8811 or as otherwise required by the Code, the name, title, address and
telephone number of the person that Holders of the Certificates may contact for
tax information relating thereto, together with such additional information at
the time or times and in the manner required by the Code. Such federal, state,
or local income tax or information returns shall be signed by the Trustee, or
such other Person as may be required to sign such returns by the Code or state
or local tax laws, regulations, or rules.

           (c) In the first federal income tax return of the REMIC for its short
taxable year ending December 31, 1998, REMIC status shall be elected for such
taxable year and all succeeding taxable years.

           (d) The Trustee will maintain or cause to be maintained such records
relating to the REMIC, including but not limited to the income, expenses, assets
and liabilities of the Trust Fund, and the initial fair market value and
adjusted basis of the Trust Fund property and assets determined at such
intervals as may be required by the Code, as may be necessary to prepare the
foregoing returns, schedules, statements or information.

           SECTION 5.06. Tax Matters Person. The Tax Matters Person shall have
the same duties with respect to the REMIC as those of a "tax matters partner"
under Subchapter C of Chapter 63 of Subtitle F of the Code. The Holder of the
Class R Certificate is hereby designated as the Tax Matters Person for the
REMIC. By its acceptance of the Class R Certificate, such Holder agrees to
irrevocably appoint the Trustee as its agent to perform all of the duties of the
Tax Matters Person for the REMIC.

           SECTION 5.07. Rights of the Tax Matters Person in Respect of the
Trustee. The Trustee shall afford the Tax Matters Person, upon reasonable notice
during normal business hours, access to all records maintained by the Trustee in
respect of its duties hereunder and access to officers of the Trustee
responsible for performing such duties. Upon request, the Trustee shall furnish
the Tax Matters Person with its most recent statement of condition publicly
available. The Trustee shall make available to the Tax Matters Person such
books, documents or records relating to the Trustee's services hereunder as the
Tax Matters Person shall reasonably request. 



                                       60
<PAGE>   67

The Tax Matters Person shall not have any responsibility or liability for any
action or failure to act by the Trustee and is not obligated to supervise the
performance of the Trustee under this Agreement or otherwise.

           SECTION 5.08. REMIC Related Covenants. For as long as the Trust shall
exist, the Trustee, the Sponsor and the Master Servicer shall act in accordance
herewith to assure continuing treatment of the Trust Fund as a REMIC and avoid
the imposition of tax on the REMIC. In particular:

                     (a) The Trustee shall not create, or permit the creation
           of, any "interests" in the REMIC within the meaning of Code Section
           860D(a)(2) other than the interests represented by the Trust Fund,
           the Regular Certificates and the Residual Certificates, respectively.

                     (b) Except as otherwise provided in the Code, the Sponsor
           and the Master Servicer shall not grant and the Trustee shall not
           accept property unless (i) substantially all of the property held in
           the REMIC constitutes either "qualified mortgages" or "permitted
           investments" as defined in Code Sections 860G(a)(3) and (5),
           respectively, and (ii) no property shall be contributed to the REMIC
           after the start-up day unless such grant would not subject the Trust
           Fund to the 100% tax on contributions to a REMIC after the start-up
           day of the REMIC imposed by Code Section 860G(d).

                     (c) The Trustee shall not accept on behalf of the REMIC any
           fee or other compensation for services and the Trustee shall not
           knowingly accept, and the Master Servicer shall not knowingly accept,
           on behalf of the Trust Fund any income from assets other than those
           permitted to be held by a REMIC.

                     (d) The Trustee shall not sell or permit the sale of all or
           any portion of the Mortgage Loans (other than in accordance with
           Sections 2.02, 2.03 or 2.08), unless such sale is pursuant to a
           "qualified liquidation" as defined in Code Section 860F(a)(4)(A) and
           in accordance with Article X.

                     (e) The Trustee shall maintain books with respect to the
           Trust on a calendar year taxable year and on an accrual basis.

           Neither the Master Servicer nor the Trustee shall engage in a
"prohibited transaction" (as defined in Code Section 860F(a)(2)), except that,
with the prior written consent of the Master Servicer and the Sponsor, the
Trustee may engage in the activities otherwise prohibited by the foregoing
paragraphs (b), (c) and (d); provided that the Master Servicer shall have
delivered to the Trustee an Opinion of Counsel to the effect that such
transaction will not result in the imposition of a tax on the REMIC and will not
disqualify the Trust Fund from treatment as a REMIC; and, provided further, that
the Master Servicer shall have demonstrated to the satisfaction of the Trustee
that such action will not adversely affect the rights of the Holders of the
Certificates and the Trustee and that such action will not adversely impact the
rating of the Certificates.

                                   ARTICLE VI

                                THE CERTIFICATES

           SECTION 6.01. The Certificates. The Classes of Senior Certificates
and the Subordinate Certificates shall be substantially in the forms set forth
in Exhibits A, B, C and D (reverse of all Certificates) and shall, on original
issue, be executed by the Trustee and shall be countersigned and delivered by
the Trustee to or upon the order of the Sponsor upon receipt by the Trustee of
the documents specified in Section 2.01. The Senior Certificates (other than the
Class A-PO and Class R Certificates) shall be available to investors in
interests representing minimum dollar Certificate Balances of $1,000 and
integral multiples of $1 in excess thereof. The Subordinate Certificates and the
Class A-PO Certificates shall be available to investors in interests
representing minimum dollar Certificate Balances of $25,000 and integral dollar
multiples of $1 in excess thereof (except one Certificate of such Class may be
issued with a different Certificate Balance). The Class R Certificates shall be
in a minimum denomination of $100. The Senior Certificates (other than the Class
R Certificates) and the Class B-1, Class B-2 and Class B-3 Certificates shall
initially be issued in book-entry form through the Depository and all other
Classes of Certificates shall initially be issued as in definitive,
fully-registered form.

           The Certificates shall be executed by manual or facsimile signature
on behalf of the Trustee by an authorized officer or signatory. Certificates
bearing the manual or facsimile signatures of individuals who were, at the time
when such signatures were affixed, authorized to sign on behalf of the Trustee
shall bind the Trustee, notwithstanding that such individuals or any of them
have ceased to be so authorized prior to the execution and delivery of such
Certificates or did not hold such offices or positions at the date of such
Certificate. No Certificate shall be entitled to any benefit under this
Agreement, or be valid for any purpose, unless such Certificate shall have been
manually countersigned by the Trustee substantially in the form provided for
herein, and such countersignature upon any Certificate shall be conclusive
evidence, and the only evidence, that such Certificate has been duly
authenticated and delivered hereunder. All Certificates shall be dated the date
of their countersignature.

           SECTION 6.02. Registration of Transfer and Exchange of Certificates.

           (a) The Trustee shall cause to be kept at an office or agency in the
city in which the Corporate Trust Office of the Trustee is located a Certificate
Register in which, subject to such reasonable regulations as it may prescribe,
the Trustee shall provide for the registration of Certificates and of transfers
and exchanges of Certificates as herein provided. The Trustee shall initially
serve as Certificate Registrar for the purpose of registering Certificates and
transfers and exchanges of Certificates as herein provided.

           (b) At the option of the Certificateholders, Certificates may be
exchanged for other Certificates of authorized denominations of a like Class,
tenor and aggregate Percentage Interest, upon surrender of the Certificates to
be exchanged at any such office or agency. Whenever any Certificates are so
surrendered for exchange, the Sponsor shall execute and the Trustee shall
authenticate, countersign and deliver the Certificates which the
Certificateholder making the exchange is entitled to receive. Every Certificate
presented or surrendered for transfer or exchange 



                                       62
<PAGE>   69

shall (if so required by the Trustee or the Certificate Registrar) be duly
endorsed by, or be accompanied by a written instrument of transfer in form
satisfactory to the Trustee and the Certificate Registrar duly executed by, the
Holder thereof or its attorney duly authorized in writing.

                  (c) (i) Except as provided in paragraph (c)(iii) below,
           the Book-Entry Certificates shall at all times remain registered in
           the name of the Depository or its nominee and at all times: (A)
           registration of the Certificates may not be transferred by the
           Trustee except to another Depository; (B) the Depository shall
           maintain book-entry records with respect to the Certificate Owners
           and with respect to ownership and transfers of such Book-Entry
           Certificates; (C) ownership and transfers of registration of the
           Book-Entry Certificates on the books of the Depository shall be
           governed by applicable rules established by the Depository; (D) the
           Depository may collect its usual and customary fees, charges and
           expenses from its Depository Participants; (E) the Trustee shall deal
           with the Depository as the representative of the Certificate Owners
           of the Book-Entry Certificates for purposes of exercising the rights
           of Holders under this Agreement, and requests and directions for and
           votes of the Depository shall not be deemed to be inconsistent if
           they are made with respect to different Certificate Owners; and (F)
           the Trustee may rely and shall be fully protected in relying upon
           information furnished by the Depository with respect to its
           Depository Participants and furnished by the Depository Participants
           with respect to indirect participating firms and persons shown on the
           books of such indirect participating firms as direct or indirect
           Certificate Owners.

                      (ii) All transfers by Certificate Owners of 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 only transfer 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.

                      (iii) If (A) (1) the Depository or the Sponsor advises the
           Trustee in writing that the Depository is no longer willing or able
           to properly discharge its responsibilities as Depository, and (2) the
           Trustee or the Sponsor is unable to locate a qualified successor, (B)
           the Sponsor at its option advises the Trustee in writing that it
           elects to terminate the book-entry system through the Depository or
           (C) after the occurrence of an Event of Default, Certificate Owners
           representing at least 51% of the aggregate Class Certificate Balances
           of the Book-Entry Certificates together advise the Trustee and the
           Depository through the Depository Participants in writing that the
           continuation of a book-entry system through the Depository is no
           longer in the best interests of the Certificate Owners, the Trustee
           shall notify all Certificate Owners, through the Depository, of the
           occurrence of any such event and of the availability of definitive,
           fully registered Certificates (the "Definitive Certificates") to
           Certificate Owners requesting the same. Upon surrender to the Trustee
           of the related Class of Certificates by the Depository, accompanied
           by the instructions from the Depository for registration, the Trustee
           shall issue the Definitive Certificates. Neither the Master Servicer,
           the Sponsor nor the Trustee shall be liable for any delay in delivery
           of such instruction and may conclusively rely on, and shall be
           protected in relying on, such instructions. The Master Servicer shall
           provide the Trustee with an adequate inventory of certificates to
           facilitate the issuance and transfer of Definitive Certificates. Upon
           the 



                                       63
<PAGE>   70

           issuance of Definitive Certificates, the Trustee shall recognize the
           Holders of the Definitive Certificates as Certificateholders
           hereunder.

           (d) No transfer of a Private Certificate shall be made unless such
transfer is exempt from the registration requirements of the 1933 Act and any
applicable state securities laws or is made in accordance with the 1933 Act and
such laws. In the event of any such transfer, (i) unless such transfer is made
in reliance on Rule 144A under the 1933 Act, the Trustee or the Sponsor may
require a written Opinion of Counsel (which may be in-house counsel) acceptable
to and in form and substance reasonably satisfactory to the Trustee and the
Sponsor that such transfer may be made pursuant to an exemption, describing the
applicable exemption and the basis therefor, from the 1933 Act and such laws or
is being made pursuant to the 1933 Act and such laws, which Opinion of Counsel
shall not be an expense of the Trustee or the Sponsor and (ii) the Trustee shall
require a certificate from the Certificateholder desiring to effect such
transfer substantially in the form attached hereto as Exhibit I-1 and a
certificate from such Certificateholder's prospective transferee substantially
in the form attached hereto either as Exhibit I-2A or as Exhibit I-2B, which
certificates shall not be an expense of the Trustee or the Sponsor; provided
that the foregoing requirements under clauses (i) and (ii) shall not apply to a
transfer of a Private Certificate between or among the Sponsor, the Seller,
their affiliates or both. The Sponsor shall provide to any Holder of a Private
Certificate and any prospective transferees designated by any such Holder,
information regarding the related Certificates and the Mortgage Loans and such
other information as shall be necessary to satisfy the condition to eligibility
set forth in Rule 144A(d)(4) for transfer of any such certificate without
registration thereof under the 1933 Act pursuant to the registration exemption
provided by Rule 144A. The Holder of a Private Certificate desiring to effect
such transfer shall, and does hereby agree to, indemnify the Trustee and the
Sponsor 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.

           (e) No transfer of an ERISA-Restricted Certificate shall be made
unless the transferee delivers to the Trustee either (i) a representation letter
in the form of Exhibit J from the transferee of such Certificate, which
representation letter shall not be an expense of the Sponsor, the Trustee or the
Master Servicer, or (ii) in the case of any ERISA-Restricted Certificate
presented for registration in the name of (A) an employee benefit plan or
arrangement to which both ERISA and the Code apply, (B) an individual retirement
account established under Code Section 408 (whether or not subject to ERISA),
(C) any other employee benefit plan which is not subject to ERISA but which is
subject to ERISA-like requirements as well as the prohibited transaction
provisions of the Code, (D) a governmental plan (as defined in Section 3(32) of
ERISA) or (E) a church plan (as defined in Section 3(33) of ERISA), or a trustee
or custodian of any of the foregoing, an Opinion of Counsel in form and
substance satisfactory to the Trustee and the Master Servicer to the effect that
the purchase or holding of such ERISA-Restricted Certificate will not result in
the assets of the Trust Fund being deemed to be "plan assets" and subject to the
prohibited transaction provisions of ERISA and the Code and will not subject the
Trustee, the Sponsor, the Seller or the Master Servicer to any obligation in
addition to those undertaken in this Agreement, which Opinion of Counsel shall
not be an expense of the Trustee or the Master Servicer. Notwithstanding
anything else to the contrary herein, any purported transfer of an
ERISA-Restricted Certificate to or on behalf of an employee benefit plan subject
to ERISA or to the Code, or an IRA without the delivery to the Trustee and the
Master Servicer of an Opinion of Counsel satisfactory to the Trustee and the
Master Servicer as described above shall be void and of no effect.


                                       64
<PAGE>   71

           Neither the Trustee nor the Certificate Registrar shall have any
liability for transfers of Book-Entry Certificates made through the book-entry
facilities of DTC or between or among any Depository Participants or Certificate
Owners, made in violation of applicable restrictions. The Trustee may rely and
shall be fully protected in relying upon information furnished by the Depository
with respect to its Depository Participants and furnished by the Depository
Participants with respect to indirect participating firms and Persons shown on
the books of such indirect participating firms as direct or indirect Certificate
Owners.

           To the extent permitted under applicable law (including, but not
limited to, ERISA), the Trustee shall be under no liability to any Person for
any registration of transfer of any ERISA-Restricted Certificate that is in fact
not permitted by this Section 6.02 or for making any payments due on such
Certificate to the Holder thereof or taking any other action with respect to
such Holder under the provisions of this Agreement so long as the transfer was
registered by the Trustee in accordance with the foregoing requirements.

           (f) 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 appointed the Trustee or its designee as its attorney-in-fact
to negotiate the terms of any mandatory sale under clause (vi) below and to
execute all instruments of transfer and to do all other things necessary in
connection with any such sale, and the rights of each Person acquiring any
Ownership Interest in a Residual Certificate are expressly subject to the
following provisions:

                     (i) 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.

                     (ii) No Person shall acquire an Ownership Interest in a
           Residual Certificate unless such Ownership Interest is a pro rata
           undivided interest.

                     (iii) In connection with any proposed transfer of any
           Ownership Interest in a Residual Certificate, the Trustee shall
           require delivery to it, in form and substance satisfactory to it, of
           an affidavit in the form of Exhibit K hereto from the proposed
           transferee.

                     (iv) Notwithstanding the delivery of an affidavit by a
           proposed transferee under clause (iii) above, if a Responsible
           Officer of the Trustee has actual knowledge that the proposed
           transferee is not a Permitted Transferee, no Transfer of any
           Ownership Interest in a Residual Certificate to such proposed
           transferee shall be effected.

                     (v) No Ownership Interest in a Residual Certificates may be
           purchased by or transferred to any Person that is not a U.S. Person,
           unless (i) such Person holds such Residual Certificate in connection
           with the conduct of a trade or business within the United States and
           furnishes the transferor and the Trustee with an effective Internal
           Revenue Service Form 4224 or (ii) the transferee delivers to both the
           transferor and the Trustee an Opinion of Counsel from a
           nationally-recognized tax counsel to the effect that such transfer




                                       65
<PAGE>   72

           is in accordance with the requirements of the Code and the
           regulations promulgated thereunder and that such transfer of the
           Residual Certificate will not be disregarded for federal income tax
           purposes.

                     (vi) Any attempted or purported transfer of any Ownership
           Interest in a Residual Certificate in violation of the provisions of
           this Section 6.02 shall be absolutely null and void and shall vest no
           rights in the purported transferee. If any purported transferee
           shall, in violation of the provisions of this Section 6.02, become a
           Holder of a Residual Certificate, then the prior Holder of such
           Residual Certificate that is a Permitted Transferee shall, upon
           discovery that the registration of transfer of such Residual
           Certificate was not in fact permitted by this Section 6.02, be
           restored to all rights as Holder thereof retroactive to the date of
           registration of 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 6.02 or for making any distributions due on such
           Residual Certificate to the Holder thereof or taking any other action
           with respect to such Holder under the provisions of the Agreement so
           long as the transfer was registered in accordance with this Section
           6.02. The Trustee shall be entitled to recover from any Holder of a
           Residual Certificate that was in fact not a Permitted Transferee at
           the time such distributions were made all distributions made on such
           Residual Certificate. Any such distributions so recovered by the
           Trustee shall be distributed and delivered by the Trustee to the
           prior Holder of such Residual Certificate that is a Permitted
           Transferee.

                     (vii) If any Person other than a Permitted Transferee
           acquires any Ownership Interest in a Residual Certificate in
           violation of the restrictions in this Section 6.02, then the Trustee
           shall have the right but not the obligation, without notice to the
           Holder of such Residual Certificate or any other Person having an
           Ownership Interest therein, to arrange for the sale of such Residual
           Certificate. The proceeds of such sale, net of commissions (which may
           include commissions payable to the Trustee or its affiliates),
           expenses and taxes due, if any, will be remitted by the Trustee to
           the previous Holder of such Residual Certificate that is a Permitted
           Transferee, except that in the event that the Trustee determines that
           the Holder of such Residual Certificate may be liable for any amount
           due under this Section 6.02 or any other provisions of this
           Agreement, the Trustee may withhold a corresponding amount from such
           remittance as security for such claim. The terms and conditions of
           any sale under this clause (vi) shall be determined in the sole
           discretion of the Trustee, and it shall not be liable to any Person
           having an Ownership Interest in a Residual Certificate as a result of
           its exercise of such discretion.

                     (viii) If any Person other than a Permitted Transferee
           acquires any Ownership Interest in a Residual Certificate in
           violation of the restrictions in this Section 6.02, then the Trustee,
           based on information provided to the Trustee by the Master Servicer,
           will provide to the Internal Revenue Service, and to the Persons
           specified in Section 860E(e)(3) and (6) of the Code, information
           needed to compute the tax imposed under Section 860E(e) of the Code
           on transfers of residual interests to disqualified organizations. The
           expenses of the Trustee under this clause (vii) shall be reimbursable
           by the Trust.

           (g) The foregoing provisions of Section 6.02 (other than the
provisions of Sections 6.02(e) and 6.02(f)(iii)(B)) shall cease to apply to
transfers occurring on or after the date on which 



                                       66
<PAGE>   73

there shall have been delivered to the Trustee, in form and substance
satisfactory to the Trustee, (i) written notification from each Rating Agency
that the removal of the restrictions on Transfer set forth in this Section 6.02
will not cause such Rating Agency to downgrade its rating of the Certificates
and (ii) an Opinion of Counsel to the effect that such removal will not cause
the Trust Fund to fail to qualify as a REMIC.

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

           (i) All Certificates surrendered for transfer and exchange shall be
destroyed by the Certificate Registrar.

           SECTION 6.03. Mutilated, Destroyed, Lost or Stolen Certificates. If
(a) any mutilated Certificate is surrendered to the Certificate Registrar or the
Certificate Registrar receives evidence to its satisfaction of the destruction,
loss or theft of any Certificate, and (b) there is delivered to the Trustee, the
Sponsor and the Certificate Registrar such security or indemnity reasonably
satisfactory to each, to save each of them harmless, then, in the absence of
actual notice to the Trustee or the Certificate Registrar that such Certificate
has been acquired by a bona fide purchaser, the Trustee shall countersign and
deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or
stolen Certificate, a new Certificate of like tenor, Class and Percentage
Interest but bearing a number not contemporaneously outstanding. 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 and the Certificate Registrar) connected therewith.
Any duplicate Certificate issued pursuant to this Section shall constitute
complete and indefeasible evidence of ownership in the Trust, as if originally
issued, whether or not the lost, stolen or destroyed Certificate shall be found
at any time.

           SECTION 6.04. Persons Deemed Owners. Prior to due presentation of a
Certificate for registration of transfer, the Sponsor, the Master Servicer, the
Trustee, the Certificate Registrar and any agent of the Sponsor, the Master
Servicer, the Trustee or the Certificate Registrar 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 5.01 and for all other
purposes whatsoever, and none of the Sponsor, the Master Servicer, the Trustee,
the Certificate Registrar or any agent of the Master Servicer, the Trustee or
the Certificate Registrar shall be affected by notice to the contrary.


                                   ARTICLE VII

                       THE SPONSOR AND THE MASTER SERVICER

           SECTION 7.01. Respective Liabilities of the Sponsor and the Master
Servicer. The Sponsor and the Master Servicer shall each be liable in accordance
herewith only to the extent of the 



                                       67
<PAGE>   74

obligations specifically and respectively imposed upon and undertaken by the
Sponsor and the Master Servicer herein. By way of illustration and not
limitation, the Sponsor is not liable for the servicing and administration of
the Mortgage Loans, nor is it obligated by Section 8.01 to assume any
obligations of the Master Servicer or to appoint a designee to assume such
obligations, nor is it liable for any other obligation hereunder that it may,
but is not obligated to, assume unless it elects to assume such obligation in
accordance herewith.

           SECTION 7.02. Merger or Consolidation of the Sponsor or the Master
Servicer. The Sponsor and the Master Servicer will each keep in full effect its
existence, rights and franchises as a corporation under the laws of the state of
its incorporation, and will each 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 Sponsor or the Master Servicer may be
merged or consolidated, or any corporation resulting from any merger or
consolidation to which the Sponsor or the Master Servicer shall be a party, or
any Person succeeding to the business of the Sponsor or the Master Servicer,
shall be the successor of the Sponsor 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 service mortgage loans on behalf of
FNMA or FHLMC.

           SECTION 7.03. Limitation on Liability of the Sponsor, the Master
Servicer and Others. None of the Sponsor, the Master Servicer or any of the
directors, officers, employees or agents of the Sponsor or of 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 Sponsor, the Master
Servicer or any such person against any breach of warranties or representations
made herein or any 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
Sponsor, the Master Servicer and any director, officer, employee or agent of the
Sponsor 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 Sponsor, the Master Servicer and any director,
officer, employee or agent of the Sponsor or the Master Servicer shall be
indemnified by the Trust Fund and held harmless against any loss, liability or
expense incurred in connection with any legal action relating to this Agreement
or the Certificates, other than any loss, liability or expense related to any
specific Mortgage Loan or Mortgage Loans (except as any such loss, liability or
expense shall be otherwise reimbursable pursuant to this Agreement) and 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 Sponsor 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 Sponsor or the Master Servicer may in its
discretion undertake any such action which it may deem necessary or desirable in
respect 



                                       68
<PAGE>   75

to this Agreement and the rights and duties of the parties hereto and the
interests of the Certificateholders hereunder. In such event, the legal expenses
and costs of such action and any liability resulting therefrom shall be
expenses, costs and liabilities of the Trust Fund, and the Sponsor and the
Master Servicer shall be entitled to be reimbursed therefor out of amounts
attributable to the Mortgage Loans on deposit in the Collection Account as
provided by Section 3.11.

           SECTION 7.04. Sponsor and Master Servicer Not to Resign. Subject to 
the provisions of Section 7.02, neither the Sponsor nor the Master Servicer
shall resign from its respective obligations and duties hereby imposed on it
except upon determination that its duties hereunder are no longer permissible
under applicable law. Any such determination permitting the resignation of the
Sponsor or the Master Servicer shall be evidenced by an Opinion of Counsel to
such effect delivered to the Trustee. No such resignation by the Master Servicer
shall become effective until the Trustee or a successor servicer shall have
assumed the Master Servicer's responsibilities and obligations in accordance
with Section 8.05 hereof.


                                  ARTICLE VIII

                                     DEFAULT

           SECTION 8.01. Events of Default. If any one of the following events
("Events of Default") shall occur and be continuing:

                     (a) any failure by the Master Servicer to deposit amounts
           in the Collection Account in the amount and manner provided herein so
           as to enable the Trustee to distribute to Holders of Certificates any
           payment required to be made under the terms of such Certificates and
           this Agreement (other than the payments required to be made under
           Section 3.20) which continues unremedied for a period of five days;
           or

                     (b) failure on the part of the Master Servicer duly to
           observe or perform in any material respect any other covenants or
           agreements of the Master Servicer set forth in the Certificates or in
           this Agreement, which covenants and agreements continue unremedied
           for a period of 30 days after the date on which written notice of
           such failure, requiring the same to be remedied, shall have been
           given to the Master Servicer by the Trustee or the Sponsor, or to the
           Master Servicer, the Sponsor and the Trustee by the Holders of
           Certificates evidencing, Voting Rights aggregating not less than 25%
           of all Certificates affected thereby; or

                     (c) the entry of a decree or order by a court or agency or
           supervisory authority having jurisdiction in the premises for the
           appointment of a conservator, receiver or liquidator in any
           insolvency, readjustment of debt, marshalling of assets and
           liabilities or similar proceedings against the Master Servicer, or
           for the winding up or liquidation of the Master Servicer's affairs,
           and the continuance of any such decree or order unstayed and in
           effect for a period of 60 consecutive days; or


                                       69
<PAGE>   76

                     (d) the consent by the Master Servicer to the appointment
           of a conservator or receiver or liquidator in any insolvency,
           readjustment of debt, marshalling of assets and liabilities or
           similar proceedings of or relating to the Master Servicer or of or
           relating to substantially all of its property; or the Master Servicer
           shall admit in writing its inability to pay its debts generally as
           they become due, file a petition to take advantage of any applicable
           insolvency or reorganization statute, make an assignment for the
           benefit of its creditors, or voluntarily suspend payment of its
           obligations; or

                     (e) the failure of the Master Servicer to remit any Monthly
           Advance required to be remitted pursuant to Section 3.20 which
           failure continues unremedied at 3:00 p.m. on the related Distribution
           Date;

then, and in each and every such case, so long as an Event of Default shall not
have been remedied by the Master Servicer, either the Trustee or the Sponsor
may, and at the direction of the Holders of Certificates evidencing Voting
Rights aggregating not less than 51% of all Certificates affected thereby shall,
by notice then given in writing to the Master Servicer (and to the Trustee, if
given by the Sponsor, and to the Sponsor, if given by the Trustee), terminate
all of the rights and obligations of the Master Servicer under this Agreement.
If an Event of Default described in clause (e) hereof shall occur, the Trustee
shall, by notice to the Master Servicer, terminate all of the rights and
obligations of the Master Servicer under this Agreement and in and to the
Mortgage Loans and proceeds thereof and the Trustee or a successor Master
Servicer appointed pursuant to Section 8.05 shall make the Advance which the
Master Servicer failed to make. On or after the receipt by the Master Servicer
of such written notice, all authority and power of the Master Servicer under
this Agreement, whether with respect to the Certificates or the Mortgage Loans
or otherwise, shall pass to and be vested in the Trustee pursuant to and under
this Section 8.01, unless and until such time as the Trustee shall appoint a
successor Master Servicer pursuant to Section 8.05, 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 of the Mortgage Loans and related
documents, or otherwise, including, without limitation, the recordation of the
assignments of the Mortgage Loans to it. The Master Servicer agrees to cooperate
with the Trustee in effecting the termination of the responsibilities and rights
of the Master Servicer hereunder, including, without limitation, the transfer to
the Trustee for the administration by it of all cash amounts that have been
deposited by the Master Servicer in the Collection Account or thereafter
received by the Master Servicer with respect to the Mortgage Loans. Upon
obtaining notice or knowledge of the occurrence of any Event of Default, the
Person obtaining such notice or knowledge shall give prompt written notice
thereof to Certificateholders at their respective addresses appearing in the
Certificate Register and to each Rating Agency. All costs and expenses
(including attorneys' fees) incurred in connection with transferring the
Mortgage Files to the successor Master Servicer and amending this Agreement to
reflect such succession as Master Servicer pursuant to this Section 8.01 shall
be paid by the predecessor Master Servicer. Notwithstanding the termination of
the Master Servicer pursuant hereto, the Master Servicer shall remain liable for
any causes of action arising out of any Event of Default occurring prior to such
termination.


                                       70

           SECTION 8.02. Remedies of Trustee. During the continuance of any
Event of Default, so long as such Event of Default shall not have been remedied,
the Trustee, in addition to the rights specified in Section 8.01, shall have the
right, in its own name as trustee of an express trust, to take all actions now
or hereafter existing at law, in equity or by statute to enforce its rights and
remedies and to protect the interests, and enforce its rights and remedies, of
the Certificateholders (including the institution and prosecution of all
judicial, administrative and other proceedings and the filing of proofs of claim
and debt in connection therewith). Except as otherwise expressly provided in
this Agreement, no remedy provided for by this Agreement shall be exclusive of
any other remedy, and each and every remedy shall be cumulative and in addition
to any other remedy and no delay or omission to exercise any right or remedy
shall impair any such right or remedy or shall be deemed to be a waiver of any
Event of Default.

           SECTION 8.03. Directions by Certificateholders and Duties of Trustee
During Event of Default. During the continuance of any Event of Default, Holders
of Certificates evidencing Voting Rights aggregating not less than 25% of each
Class of Certificates affected thereby may direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee, or exercising
any trust or power conferred upon the Trustee under this Agreement; provided,
however, that the Trustee shall be under no obligation to pursue any such
remedy, or to exercise any of the trusts or powers vested in it by this
Agreement (including, without limitation, (a) the conducting or defending of any
administrative action or litigation hereunder or in relation hereto, and (b) the
terminating of the Master Servicer or any successor Master Servicer from its
rights and duties as master servicer hereunder) at the request, order or
direction of any of the Certificateholders, unless such Certificateholders shall
have offered to the Trustee reasonable security or indemnity against the costs,
expenses and liabilities which may be incurred therein or thereby and, provided
further, that, subject to the provisions of Section 9.01, the Trustee shall have
the right to decline to follow any such direction if the Trustee, based upon an
Opinion of Counsel, determines that the action or proceeding so directed may not
lawfully be taken or if the Trustee in good faith determines that the action or
proceeding so directed would involve it in personal liability or be unjustly
prejudicial to the non-assenting Certificateholders.

           SECTION 8.04. Action upon Certain Failures of the Master Servicer and
upon Event of Default. In the event that the Trustee shall have knowledge of any
failure of the Master Servicer specified in Section 8.01(a) or (b) which would
become an Event of Default upon the Master Servicer's failure to remedy the same
after notice, the Trustee may, but need not if the Trustee deems it not in the
Certificateholder's best interest, give notice thereof to the Master Servicer.
If the Trustee shall have knowledge of an Event of Default, the Trustee shall
give prompt written notice thereof to the Certificateholders.

           SECTION 8.05. Trustee to Act; Appointment of Successor.

           (a) On and after the time the Master Servicer receives a notice of
termination pursuant to Section 8.01, the Trustee 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 to all the responsibilities, duties and liabilities relating thereto
placed on the Master Servicer by the terms and provisions hereof.
Notwithstanding anything provided herein to the contrary, under no circumstances
shall any provision of this Agreement be construed to 



                                       71
<PAGE>   78

require the Trustee, acting in its capacity as successor to the Master Servicer
in its obligation to make Advances, to advance, expend or risk its own funds or
otherwise incur any financial liability in the performance of its duties
hereunder if it shall have reasonable grounds for believing that such funds are
non-recoverable. Subject to Section 8.05(b), as compensation therefor, the
Trustee shall be entitled to such compensation as the Master Servicer would have
been entitled to hereunder if no such notice of termination had been given.
Notwithstanding the above, the Trustee may, if it shall be unwilling so to act,
or shall, if it is legally unable so to act, appoint, or petition a court of
competent jurisdiction to appoint, any established housing and home finance
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;
provided, however, that any such institution appointed as successor Master
Servicer shall not as evidenced in writing by each Rating Agency adversely
affect the then current rating of any Class of Certificates immediately prior to
the termination of the Master Servicer. The appointment of a successor Master
Servicer shall not affect any liability of the predecessor Master Servicer which
may have arisen under this Agreement prior to its termination as Master
Servicer, nor shall any successor Master Servicer be liable for any acts or
omissions of the predecessor Master Servicer or for any breach by such Master
Servicer of any of its representations or warranties contained herein or in any
related document or agreement. Pending appointment of a successor to the Master
Servicer hereunder, unless the Trustee is prohibited by law from so acting, the
Trustee shall act in such capacity as provided above. The Trustee and such
successor shall take such action, consistent with this Agreement, as shall be
necessary to effectuate any such succession.

           (b) In connection with the appointment of a successor Master Servicer
or the assumption of the duties of the Master Servicer, as specified in Section
8.05(a), 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 any Person assuming the duties of Master Servicer
as successor to NationsBanc Mortgage Corporation shall pay to NationsBanc
Mortgage Corporation an amount equal to the market value of the portion of the
Master Servicing Fee that will accrue in the future due to the Master Servicing
Fee Rate exceeding 0.25% per annum with respect to any Mortgage Loan. The
"market value" of such portion of the Master Servicing Fee shall be determined
by NationsBanc Mortgage Corporation on the basis of at least two quotations from
third parties actively engaged in the servicing of single-family mortgage loans.
If the successor Master Servicer does not agree that such market value is a fair
price, such successor shall obtain two quotations of market value from third
parties actively engaged in the servicing of single-family mortgage loans. The
market value of the excess portion of the Master Servicing Fee will then be
equal to the average of (i) the lowest figure obtained by NationsBanc Mortgage
Corporation and (ii) the highest figure obtained by the successor Master
Servicer. Payment of the amount calculated above shall be made to NationsBanc
Mortgage Corporation by the successor Master Servicer no later than the last
Business Day of the month in which such successor Master Servicer becomes
entitled to receive the Master Servicing Fee under this Agreement. In no event
will any portion of the Trust Fund be used to pay amounts due to NationsBanc
Mortgage Corporation under this Section 8.05(b).

           (c) Any successor, including the Trustee, to the Master Servicer as
master servicer shall during the term of its service as master servicer maintain
in force (i) a policy or policies of insurance covering errors and omissions in
the performance of its obligations as servicer hereunder and (ii) a 



                                       72

fidelity bond in respect of its officers, employees and agents to the same
extent as the Master Servicer is so required pursuant to Section 3.03.

           SECTION 8.06. Notification to Certificateholders. Upon any
termination or appointment of a successor to the Master Servicer pursuant to
this Article VIII, the Trustee shall give prompt written notice thereof to
Certificateholders at their respective addresses appearing in the Certificate
Register and to each Rating Agency.


                                   ARTICLE IX

                                   THE TRUSTEE

           SECTION 9.01. Duties of Trustee.

           (a) The Trustee, except during the continuance of an Event of
Default, undertakes to perform such duties and only such duties as are
specifically set forth in this Agreement. In case of an Event of Default (which
has not been cured), 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 investor would exercise or use under the
circumstances in the conduct of such investor's own affairs.

           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 to determine whether they are in
the form required by this Agreement; provided, however, that the Trustee shall
not be responsible for the accuracy or content of any such certificate,
statement, opinion, report, or other order or instrument.

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

                      (i) this paragraph shall not be construed to limit the
           effect of Section 9.01(a);

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

                     (iii) the Trustee and co-trustee shall not be personally
           liable with respect to any action taken, suffered or omitted to be
           taken by it in good faith in accordance with the direction of
           Certificateholders as provided in Section 8.03;

                     (iv) for all purposes under this Agreement, the Trustee
           shall not be deemed to have notice of any matter, including without
           limitation those matters described in Section 8.01(b) through (e),
           unless a Responsible Officer assigned to and working in the Trustee's




                                       73

           corporate trust division has actual knowledge thereof or unless
           written notice of any event is received at the Corporate Trust
           Office, and such notice references the Certificates and this
           Agreement;

                     (v) no provision of this Agreement shall require the
           Trustee to expend or risk its own funds or otherwise incur any
           financial liability in the performance of any of its duties
           hereunder, or in the exercise of any of its rights or powers, if it
           shall have reasonable grounds for believing that repayment of such
           funds or adequate indemnity against such risk or liability is not
           reasonably assured to it and none of the provisions contained in this
           Agreement shall in any event require the Trustee to perform, or be
           responsible for the manner of performance of, any of the obligations
           of the Sponsor or the Master Servicer under this Agreement, except
           during such time, if any, as the Trustee shall be the successor to
           the Master Servicer in accordance with the terms of this Agreement or
           as otherwise specifically set forth in this Agreement; and

                     (vi) prior to the occurrence of an Event of Default as
           described in the first paragraph of this Section 9.01 and after the
           curing 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.

           SECTION 9.02. Certain Matters Affecting the Trustee. Except as
otherwise provided in Section 9.01:

                     (a) the Trustee may rely and shall be protected in acting
           or refraining from acting upon any resolution, Officer's Certificate,
           certificate of auditor or any other certificate, statement,
           instrument, opinion, report, notice, request, consent, order,
           approval, bond or other paper or document 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 with such Opinion of Counsel;

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

                     (d) unless an Event of Default shall have occurred and be
           continuing and, in each case is known to a Responsible Officer of the
           Trustee, the Trustee shall not be bound to make any investigation
           into the facts or matters stated in any resolution, certificate,




                                       74
<PAGE>   81

           statement, instrument, opinion, report, notice, request, consent,
           order, approval, bond or other paper or document, unless requested in
           writing to do so by Holders of Certificates evidencing not less than
           50% of the Percentage Interests of each Class of Certificates;
           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, not reasonably assured to the Trustee by the security
           afforded to it by the terms of this Agreement, the Trustee may
           require reasonable indemnity against such expense or liability or
           payment of such estimated expenses as a condition to proceeding; and

                     (e) the Trustee and any co-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 the Trustee and any
           co-trustee shall not be responsible for any willful misconduct or
           gross negligence on the part of any agent or attorney appointed with
           due care by it hereunder.

           SECTION 9.03. Trustee Not Liable for Certificates or Mortgage Loans.
The recitals contained herein (other than those relating to the due
organization, power and authority of the Trustee) and in the Certificates (other
than the execution of, and the counter-signature on the Certificates) shall be
taken as the statements of the Sponsor or Master Servicer, as applicable, and
the Trustee assumes no responsibility for their corrections. The Trustee makes
no representations as to the validity or sufficiency of this Agreement or of the
Certificates or any Mortgage Loans save that the Trustee represents that,
assuming due execution and delivery by the other parties hereto, this Agreement
has been duly authorized, executed and delivered by it and constitutes its
legal, valid and binding obligation, enforceable against it in accordance with
its terms, subject, as to enforcement of remedies, to applicable insolvency,
receivership, moratorium and other laws affecting the rights of creditors
generally, and to general principles of equity and the discretion of the court
(regardless of whether enforcement of such remedies is considered in a
proceeding in equity or at law). The Trustee shall not be accountable for the
use or application by the Sponsor of funds paid to the Sponsor in consideration
of the assignment of the Mortgage Loans hereunder by the Sponsor, or for the use
or application of any funds paid to Servicers or the Master Servicer in respect
of the Mortgage Loans or deposited into the Collection Account, or any other
account hereunder (other than the Distribution Account) by the Master Servicer.

           The Trustee shall at no time have any responsibility or liability for
or with respect to the legality, validity and enforceability of any Mortgage or
any Mortgage Loan, or the perfection and priority of any Mortgage or the
maintenance of any such perfection and priority or for or with respect to the
sufficiency of the Trust or its ability to generate the payments to be
distributed to Certificateholders under this Agreement, including, without
limitation: the existence, condition and ownership of any Mortgaged Property;
the existence and enforceability of any hazard insurance thereon (other than if
the Trustee shall assume the duties of the Master Servicer pursuant to Section
8.05 and thereupon only for the acts or omissions of the successor Master
Servicer); the validity of the assignment of any Mortgage Loan to the Trustee or
of any intervening assignment; the completeness of any Mortgage Loan; the
performance or enforcement of any Mortgage Loan (other than if the Trustee shall
assume the duties of the Master Servicer pursuant to Section 8.05 and thereupon
only for the acts or omissions of the Trustee as successor Master Servicer); the
compliance by the Sponsor or the Master Servicer 



                                       75
<PAGE>   82

with any warranty or representation made under this Agreement or in any related
document or the accuracy of any such warranty or representation; any investment
of monies by or at the direction of the Master Servicer or any loss resulting
therefrom, it being understood that the Trustee shall remain responsible for any
Trust property that it may hold in its individual capacity; the acts or
omissions of any of the Sponsor, the Master Servicer (other than if the Trustee
shall assume the duties of the Master Servicer pursuant to Section 8.05 and
thereupon only for the acts or omissions of the Trustee as successor Master
Servicer), any Servicer or any Mortgagor; any action of the Master Servicer
(other than if the Trustee shall assume the duties of the Master Servicer
pursuant to Section 8.05 and thereupon only for the acts or omissions of the
Trustee as successor Master Servicer) or any Servicer taken in the name of the
Trustee; the failure of the Master Servicer or any Servicer to act or perform
any duties acquired of it as agent of the Trustee hereunder; or any action by
the Trustee taken at the instruction of the Master Servicer (other than if the
Trustee shall assume the duties of the Master Servicer pursuant to Section 8.05
and thereupon only for the acts or omissions of the Trustee as successor Master
Servicer); provided, however, that the foregoing shall not relieve the Trustee
of its obligation to perform its duties under this Agreement, including, without
limitation, the Trustee's review of the Mortgage Files pursuant to Section 2.02.
The Trustee shall file any financing or continuation statement in any public
office at any time required to maintain the perfection of any security interest
or lien granted to it hereunder.

           SECTION 9.04. Trustee May Own Certificates. The Trustee in its
individual or any other capacity 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 Master Servicer, any Servicer or any of their respective affiliates
with the same right it would have if it were not the Trustee.

           SECTION 9.05. Eligibility Requirements for Trustee. The Trustee
hereunder shall at all times be (a) an institution the deposits of which are
fully insured by the FDIC and (b) a corporation or national banking association
organized and doing business under the laws of the United States of America or
of any State, authorized under such laws to exercise corporate trust powers,
having a combined capital and surplus of not less than $30,000,000 and subject
to supervision or examination by Federal or State authority and (c) with respect
to every successor trustee hereunder either an institution (i) the long-term
unsecured debt obligations of which are rated at least "A" by S&P and "A" by
Fitch or (ii) whose serving as Trustee hereunder would not result in the
lowering of the ratings originally assigned to any Class of Certificates. The
Trustee shall not be an affiliate of the Sponsor or the Master Servicer. If such
corporation or national banking association 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 9.05,
the combined capital and surplus of such corporation or national banking
association shall be deemed to be its combined capital and surplus as set forth
in its most recent report of condition so published. In case at any time the
Trustee shall cease to be eligible in accordance with the provision of this
Section 9.05, the Trustee shall resign immediately in the manner and with the
effect specified in Section 9.06.

           SECTION 9.06. Resignation and Removal of Trustee. The Trustee may at
any time resign and be discharged from the trust hereby created by giving
written notice thereof to the Master Servicer and mailing a copy of such notice
to all Holders of record. The Trustee shall also mail a 



                                       76
<PAGE>   83

copy of such notice of resignation to each Rating Agency. Upon receiving such
notice of resignation, the Master Servicer shall use its best efforts to
promptly appoint a successor Trustee by written instrument, in duplicate, one
copy of which instrument shall be delivered to the resigning Trustee and one
copy to the successor Trustee. If no successor Trustee shall have been so
appointed and shall have accepted appointment within 30 days after the giving of
such notice of resignation, the resigning Trustee may petition any court of
competent jurisdiction for the appointment of a successor Trustee.

           If at any time the Trustee shall cease to be eligible in accordance
with the provisions of Section 9.05 and shall fail to resign after written
request therefor by the Master Servicer, or if at any time the Trustee shall
become incapable of acting, or shall be adjudged a 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 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, then the
Master Servicer may remove the Trustee and appoint a successor trustee by
written instrument, in duplicate, one copy of which instrument shall be
delivered to the Trustee so removed and one copy to the successor.

           The Holders of Certificates evidencing not less than 50% of the
Voting Rights may at any time remove the Trustee by written instrument or
instruments delivered to the Master Servicer and the Trustee; the Master
Servicer shall thereupon use its best efforts to appoint a successor Trustee in
accordance with this Section 9.06.

           Any resignation or removal of the Trustee and appointment of a
successor Trustee pursuant to any of the provisions of this Section 9.06 shall
become effective upon acceptance of appointment by the successor Trustee as
provided in Section 9.07.

           SECTION 9.07. Successor Trustee. Any successor Trustee appointed as
provided in Section 9.06 shall execute, acknowledge and deliver to the Master
Servicer and to its predecessor Trustee an instrument accepting such appointment
hereunder, and thereupon the resignation or removal of the predecessor Trustee
shall become effective and such successor Trustee, without any further act, deed
or conveyance, shall become fully vested with all the rights, powers, duties and
obligations of its predecessor hereunder, with like effect as if originally
named as Trustee herein. The predecessor Trustee shall duly assign, transfer,
deliver and pay over to the successor Trustee the whole of the Mortgage Files
and related documents and statements held by it hereunder, together with all
instruments of transfer and assignment or other documents properly executed as
may be reasonably required to effect such transfer and such of the records or
copies thereof maintained by the predecessor Trustee in the administration
hereof as may be reasonably requested by the successor Trustee and shall
thereupon be discharged from all duties and responsibilities under this
Agreement; provided, however, that if the predecessor Trustee has been
terminated pursuant to the third paragraph of Section 9.06, all reasonable
expenses of the predecessor Trustee incurred in complying with this Section 9.07
shall be reimbursed by the Trust.

           No successor Trustee shall accept appointment as provided in this
Section 9.07 unless at the time of such appointment such successor Trustee shall
be eligible under the provisions of Section 9.05.


                                       77
<PAGE>   84

           Upon acceptance of appointment by a successor Trustee as provided in
this Section 9.07, 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 and to each Rating Agency. 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 9.08. Merger or Consolidation of Trustee. Any corporation or
national banking association into which the Trustee may be merged or converted
or with which it may be consolidated, or any corporation or national banking
association resulting from any merger, conversion or consolidation to which the
Trustee shall be a party, or any corporation or national banking association
succeeding to all or substantially all of the corporate trust business of the
Trustee, shall be the successor of the Trustee hereunder, if such corporation or
national banking association is eligible under the provisions of Section 9.05,
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 9.09. Appointment of Co-Trustee or Separate Trustee.
Notwithstanding any of the provisions hereof, at any time, for the purpose of
meeting any legal requirements of any jurisdiction in which any Mortgaged
Property may at the time be located or for any other reason, 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,
as co-trustee or separate trustee, 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 provision of this Section 9.09,
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 ten days after the receipt by it of a
request to do so, the Trustee alone shall have the power to make such
appointment. No co-trustee or separate trustee hereunder shall be required to
meet the terms of eligibility as a successor Trustee under Section 9.05 and no
notice to Holders of Certificates of the appointment of co-trustee(s) or
separate trustee(s) shall be required under Section 9.07.

           In the case of any appointment of a co-trustee or separate trustee
pursuant to this Section 9.09, all rights, powers, duties and obligations
conferred or imposed upon the Trustee shall be conferred or imposed upon and
exercised or performed by the Trustee and such separate trustee 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. No trustee
hereunder shall be held personally liable by reason of any act or omission of
any other trustee hereunder; provided, however, that no appointment of a
co-trustee or separate trustee hereunder shall relieve the Trustee of its
obligations hereunder.


                                       78
<PAGE>   85

           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 IX. Each separate trustee and co-trustee, upon its acceptance of
the trusts conferred, shall be vested with the estates or property specified in
its instrument of appointment, either jointly with the Trustee or separately, as
may be provided therein, subject to all the provisions of this Agreement,
specifically including every provision of this Agreement relating to the conduct
of, affecting the liability of, or affording protection to, the Trustee. Every
such instrument shall be filed with the Trustee.

           Any separate trustee or co-trustee may, at any time, constitute the
Trustee, its agent or attorney-in-fact, with full power and authority, to the
extent not prohibited by law, to do any lawful act under or in respect of this
Agreement on its behalf and in its name. If any separate trustee or co-trustee
shall become incapable of acting, resign or be removed, or shall be adjudged a
bankrupt or insolvent, or a receiver of its property shall be appointed, or any
public officer shall take charge or control of such trustee or co-trustee or of
its property or affairs for the purpose of rehabilitation, conservation or
liquidation, 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.

           SECTION 9.10. Authenticating Agents. The Trustee may appoint one or
more authenticating agents ("Authenticating Agents") which shall be authorized
to act on behalf of the Trustee in authenticating or countersigning
Certificates. Wherever reference is made in this Agreement to the authentication
or countersigning of Certificates by the Trustee or the Trustee's certificate of
authentication or countersigning, such reference shall be deemed to include
authentication or countersigning on behalf of the Trustee by an Authenticating
Agent and a certificate of authentication or countersignature executed on behalf
of the Trustee by an Authenticating Agent. Each Authenticating Agent must be
acceptable to the Master Servicer and must be a corporation or national banking
association organized and doing business under the laws of the United States of
America or of any State, having a principal office and place of business in New
York, New York, having a combined capital and surplus of at least $15,000,000,
authorized under such laws to do a trust business and subject to supervision or
examination by Federal or State authorities.

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

           Any Authenticating Agent may at any time resign by giving written
notice of resignation to the Trustee and to the Master Servicer. The Trustee may
at any time terminate the agency of any Authenticating Agent by giving written
notice of termination to such Authenticating Agent and to the Master Servicer.
Upon receiving a notice of resignation or upon such a termination, or in case,




                                       79
<PAGE>   86

at any time any Authenticating Agent shall cease to be eligible in accordance
with the provisions of this Section 9.10, the Trustee may appoint a successor
Authenticating Agent, shall give written notice of such appointment to the
Master Servicer and shall mail notice of such appointment to all
Certificateholders. Any successor Authenticating Agent upon acceptance of its
appointment hereunder shall become vested with all the rights, powers, duties
and responsibilities of its predecessor hereunder, with like effect as if
originally named as Authenticating Agent.

           SECTION 9.11. Trustee's Fees and Expenses. The Trustee, as
compensation for its activities hereunder, shall be entitled to receive on each
Distribution Date an amount equal to the Trustee Fee for such Distribution Date
pursuant to Section 5.02(a). The Trustee and any director, officer, employee or
agent of the Trustee shall be indemnified by the Trust and held harmless against
any loss, liability or expense (including reasonable attorney's fees) (a)
incurred in connection with any claim or legal action relating to (i) this
Agreement, (ii) the Certificates, or (iii) the performance of any of the
Trustee's duties hereunder, other than any loss, liability or expense incurred
by reason of willful misfeasance, bad faith or negligence in the performance of
any of the Trustee's duties hereunder, (b) resulting from any tax or information
return which was prepared by, or should have been prepared by, the Master
Servicer and (c) arising out of the transfer of any Private Certificate not in
compliance with ERISA. Such indemnity shall survive the termination of this
Agreement or the resignation or removal of the Trustee hereunder. Without
limiting the foregoing, except as otherwise agreed upon in writing by the
Sponsor and the Trustee, and except for any such expense, disbursement or
advance as may arise from the Trustee's negligence, bad faith or willful
misconduct, the Trust shall reimburse the Trustee, for all reasonable expenses,
disbursements and advances incurred or made by the Trustee in accordance with
any of the provisions of this Agreement; provided, however, that the Sponsor and
the Trustee intend to enter into a separate agreement for custody-related
services. Except as otherwise provided herein, the Trustee shall not be entitled
to payment or reimbursement for any routine ongoing expenses incurred by the
Trustee in the ordinary course of its duties as Trustee, Certificate Registrar
or Paying Agent hereunder or for any other expenses.

           SECTION 9.12. Tax Returns. The Trustee will prepare any federal,
state and local income tax or information returns of the Trust and the REMIC and
shall file or cause to be filed such returns.

           SECTION 9.13. Paying Agents. The Trustee may appoint one or more
Paying Agents which shall be authorized to act on behalf of the Trustee in
making withdrawals from the Collection Account, and distributions to
Certificateholders as provided in Section 3.08 and Section 5.02. Wherever
reference is made in this Agreement to the withdrawal from the Collection
Account by the Trustee, such reference shall be deemed to include such a
withdrawal on behalf of the Trustee by a Paying Agent. Whenever reference is
made in this Agreement to a distribution by the Trustee or the furnishing of a
statement to Certificateholders by the Trustee, such reference shall be deemed
to include such a distribution or furnishing on behalf of the Trustee by a
Paying Agent. Each Paying Agent shall provide to the Trustee such information
concerning the Collection Account as the Trustee shall request from time to
time. Each Paying Agent must be reasonably acceptable to the Master Servicer and
must be a corporation or banking association organized and doing business under
the laws of the United States of America or of any state, having a principal
office and place of business in New York, New York, having a combined capital
and surplus of at least $15,000,000, 



                                       80
<PAGE>   87

authorized under such laws to do a trust business and subject to supervision or
examination by federal or state authorities.

           Any corporation into which any Paying Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which any Paying Agent shall be
a party, or any corporation succeeding to the corporate agency business of any
Paying Agent, shall continue to be the Paying Agent provided that such
corporation after the consummation of such merger, conversion, consolidation or
succession meets the eligibility requirements of this Section 9.13.

           Any Paying Agent may at any time resign by giving written notice of
resignation to the Trustee and to the Master Servicer; provided that the Paying
Agent has returned to the Collection Account or otherwise accounted, to the
reasonable satisfaction of the Trustee, for all amounts it has withdrawn from
the Collection Account. The Trustee may, upon prior written approval of the
Master Servicer, at any time terminate the agency of any Paying Agent by giving
written notice of termination to such Paying Agent and to the Master Servicer.
Upon receiving a notice of resignation or upon such a termination, or in case at
any time any Paying Agent shall cease to be eligible in accordance with the
provisions of the first paragraph of this Section 9.13, the Trustee may appoint,
upon prior written approval of the Master Servicer, a successor Paying Agent,
shall give written notice of such appointment to the Master Servicer and shall
mail notice of such appointment to all Certificateholders. Any successor Paying
Agent upon acceptance of its appointment hereunder shall become vested with all
rights, powers, duties and responsibilities of its predecessor hereunder, with
like effect as if originally named as Paying Agent. The Trustee shall remain
liable for any duties and obligations assumed by its appointed Paying Agent.

           SECTION 9.14. Limitation of Liability. The Certificates are executed
by the Trustee, not in its individual capacity but solely as Trustee of the
Trust, in the exercise of the powers and authority conferred and vested in it by
this Agreement. Each of the undertakings and agreements made on the part of the
Trustee in the Certificates is made and intended not as a personal undertaking
or agreement by the Trustee but is made and intended for the purpose of binding
only the Trust.

           SECTION 9.15 Trustee May Enforce Claims Without Possession of
Certificates. All rights of action and claims under this Agreement or the
Certificates may be prosecuted and enforced by the Trustee without the
possession of any of the Certificates or the production thereof in any
proceeding relating thereto, and such preceding instituted by the Trustee shall
be brought in its own name or in its capacity as Trustee. Any recovery of
judgment shall, after provision for the payment of the reasonable compensation,
expenses, disbursement and advances of the Trustee, its agents and counsel, be
for the ratable benefit or the Certificateholders in respect of which such
judgment has been recovered.

           SECTION 9.16 Suits for Enforcement. In case an Event of Default or
other default by the Master Servicer or the Sponsor hereunder shall occur and be
continuing, the Trustee, in its discretion, may proceed to protect and enforce
its rights and the rights of the Holders of Certificates under this Agreement by
a suit, action or proceeding in equity or at law or otherwise, whether for the
specific performance of any covenant or agreement contained in this Agreement 



                                       81
<PAGE>   88

or in aid of the execution of any power granted in this Agreement or for the
enforcement of any other legal, equitable or other remedy, as the Trustee, being
advised by counsel, shall deem most effectual to protect and enforce any of the
rights of the Trustee and the Certificateholders.

           SECTION 9.17 Waiver of Bond Requirement. The Trustee shall be
relieved of, and each Certificateholder hereby waives, any requirement of any
jurisdiction in which the Trust, or any part thereof, may be located that the
Trustee post a bond or other surety with any court, agency or body whatsoever.

           SECTION 9.18 Waiver of Inventory, Accounting and Appraisal
Requirement. The Trustee shall be relieved of, and each Certificateholder hereby
waives, any requirement of any jurisdiction in which the Trust, or any part
thereof, may be located that the Trustee file any inventory, accounting or
appraisal of the Trust with any court, agency or body at any time or in any
manner whatsoever.

           SECTION 9.19 Year 2000 Compliance. The Trustee covenants that it is
working to modify its computer and other systems used in the performance of its
duties as trustee and/or bond administrator for the Certificates to operate in a
manner such that, on and after January 1, 2000, the Trustee can perform its
duties in accordance with the terms of this Agreement.



                                    ARTICLE X

                                   TERMINATION

           SECTION 10.01. Termination upon Purchase by the Sponsor or
Liquidation of All Mortgage Loans. Subject to Section 10.02, the respective
obligations and responsibilities of the Sponsor, the Master Servicer and the
Trustee created hereby (other than the obligation of Trustee to make certain
payments to Certificateholders after the Final Distribution Date, the
obligations of the Master Servicer to send certain notices as hereinafter set
forth and pursuant to Sections 9.11 and 9.12 hereof and the obligation of the
Master Servicer pursuant to Section 5.05(b)) shall terminate upon the last
action required to be taken by the Trustee on the Final Distribution Date
pursuant to this Article X following the earlier of (a) the purchase by the
Sponsor of all Mortgage Loans and all REO Property remaining in the Trust Fund
at a price equal to the sum of (i) 100% of the Stated Principal Balance of each
Mortgage Loan (other than any Mortgage Loan as to which REO Property has been
acquired and whose fair market value is included pursuant to clause (ii) below)
and (ii) the fair market value of such REO Property (as determined by the
Sponsor as of the close of business on the third Business Day next preceding the
date upon which notice of any such termination is furnished to
Certificateholders pursuant to the third paragraph of this Article X), plus any
Class Unpaid Interest Shortfall for any Class of Certificates as well as one
month's interest at the related Mortgage Rate on the Stated Principal Balance of
each Mortgage Loan (including any Mortgage Loan as to which REO Property has
been acquired) or (b) 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; provided, however, that in no event shall
the Trust created hereby continue beyond the expiration of 21 years from the
death of the last survivor of the 



                                       82
<PAGE>   89

descendants of Joseph P. Kennedy, the late ambassador of the United States to
the Court of St. James, living on the date hereof.

           The right of the Sponsor to repurchase all Mortgage Loans pursuant to
(a) above is conditioned upon the Pool Stated Principal Balance as of the Final
Distribution Date being less than 5% of the Cut-Off Date Pool Principal Balance.
If such right is exercised, the Trustee shall, promptly following payment of the
purchase price, release to the Sponsor or its designee the Mortgage Files
pertaining to the Mortgage Loans being purchased.

           Notice of any termination, specifying the Final Distribution Date
(which shall be a date that would otherwise be a Distribution Date) upon which
the Certificateholders may surrender their Certificates to the Trustee for
payment of the final distribution and for cancellation, shall be given promptly
by the Sponsor (if exercising its right to purchase the assets of the Trust) or
by the Trustee (in any other case) by letter to Certificateholders mailed not
earlier than the 15th day and not later than the 25th day of the month next
preceding the month of such final distribution specifying (1) the Final
Distribution Date upon which final payment of the Certificates will be made upon
presentation and surrender of Certificates at the office or agency of the
Trustee therein designated, (2) the amount of any such final payment and (3)
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 or agency of the Trustee therein specified. If the
Sponsor is obligated to give notice to Certificateholders as aforesaid, it shall
give such notice to the Trustee and the Certificate Registrar at the time such
notice is given to Certificateholders. In the event such notice is given by the
Sponsor, the Sponsor shall deposit in the Collection Account on or before the
Final Distribution Date in immediately available funds an amount equal to the
amount necessary to make the amount, if any, on deposit in the Collection
Account on the Final Distribution Date equal to the purchase price for the
assets of the Trust computed as above provided together with a statement as to
the amount to be distributed on each Class of Certificates pursuant to the next
succeeding paragraph.

           Upon presentation and surrender of the Certificates, the Trustee
shall cause to be distributed to Certificateholders of each Class, in the order
set forth in Section 5.02 hereof, on the final Distribution Date and in
proportion to their respective Percentage Interests, with respect to
Certificateholders of the same Class, an amount equal to (I) as to each Class of
Certificates, the Class Certificate Balance thereof plus (a) accrued interest
thereon in the case of an interest bearing Certificate and (b) the Class A-PO
Deferred Amount with respect to the Class A-PO Certificates, and (II) as to the
Class R Certificates, the amount, if any, which remains on deposit in the
Distribution Account (other than the amounts retained to meet claims) after
application pursuant to clause (I) above.

           If all of the Certificateholders do not surrender their Certificates
for final payment and cancellation on or before the Final Distribution Date, the
Trustee shall on such date cause all funds in the Collection Account not
distributed in final distribution to Certificateholders to continue to be held
by the Trustee in an Eligible Account for the benefit of such Certificateholders
and the Sponsor (if it exercised its right to purchase the assets of the Trust
Fund) or the Trustee (in any other case) shall give a second written notice to
the remaining Certificateholders to surrender their Certificates for
cancellation and receive the final distribution with respect thereto. If within
one year after the 



                                       83
<PAGE>   90

second notice all the Certificates shall not have been surrendered for
cancellation, the Trustee may take appropriate steps, or may appoint an agent to
take appropriate steps, to contact the remaining Certificateholders concerning
surrender of their Certificates, and the cost thereof shall be paid out of the
funds on deposit in such Eligible Account.

           SECTION 10.02. Additional Termination Requirements.

           (a) If the Sponsor exercises its purchase option as provided in
Section 10.01, the Trust shall be terminated in accordance with the following
additional requirements, unless the Trustee has received an Opinion of Counsel
to the effect that the failure of the Trust to comply with the requirements of
this Section 10.02 will not (i) result in the imposition of taxes on "prohibited
transactions" of the Trust as defined in Section 860F of the Code, or (ii) cause
the Trust Fund to fail to qualify as a REMIC at any time that any Certificates
are outstanding:

                     (A) within 90 days prior to the Final Distribution Date set
           forth in the notice given by the Sponsor under Section 10.01, the
           Trustee shall sell all of the assets of the Trust Fund to the Sponsor
           for cash; and

                     (B) the notice given by the Sponsor or the Trustee pursuant
           to Section 10.01 shall provide that such notice constitutes the
           adopting of a plan of complete liquidation of the REMIC as of the
           date of such notice (or, if earlier, the date on which such notice
           was mailed to Certificateholders). The Trustee shall also specify
           such date in the final tax return of the REMIC.

           (b) By their acceptance of the Residual Certificates, the Holders
thereof hereby agree to take such other action in connection with such plan of
complete liquidation as may be reasonably requested by the Sponsor.


                                   ARTICLE XI

                            MISCELLANEOUS PROVISIONS

           SECTION 11.01. Amendment. This Agreement may be amended from time to
time by the Sponsor, the Master Servicer and the Trustee, without the consent of
any of the Certificateholders, (a) to cure any ambiguity, (b) to correct or
supplement any provisions herein or therein which may be defective or
inconsistent with any other provisions herein or therein, as the case may be,
(c) to modify, eliminate or add to any of its provisions to such extent as shall
be necessary to maintain the qualification of the Trust Fund as a REMIC or (d)
to add any other provisions with respect to matters or questions arising under
this Agreement which shall not be inconsistent with the provisions of this
Agreement; provided, however, that (i) as evidenced by an Opinion of Counsel in
each case such action shall not, adversely affect in any material respect the
interests of any Certificateholder, (ii) in each case, such action is necessary
or desirable to maintain the qualification of the Trust Fund as a REMIC or shall
not adversely affect such qualification and (iii) if the opinion called for in
clause (i) cannot be delivered with regard to an amendment pursuant to clause
(c) above, such amendment is necessary to maintain the qualification of the
Trust Fund as 



                                       84
<PAGE>   91

a REMIC; and, provided further, that the amendment shall not be deemed to
adversely affect in any material respect the interests of the Certificateholders
and no Opinion of Counsel to that effect shall be required if the Person
requesting the amendment obtains a letter from each Rating Agency stating that
the amendment would not result in the downgrading or withdrawal of the
respective ratings then assigned to the Certificates.

           This Agreement may also be amended from time to time by the Sponsor,
the Master Servicer and the Trustee, with the consent of the Holders of
Certificates of each Class of Certificates which is affected by such amendment,
evidencing, as to each such Class of Certificates, Percentage Interests
aggregating not less than 66-2/3%, 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 such Certificates;
provided, however, that no such amendment shall (A) reduce in any manner the
amount of, or delay the timing of, collections of payments on Mortgage Loans or
distributions which are required to be made on any Certificate without the
consent of the Holder of such Certificate or (B) reduce the aforesaid percentage
required to consent to any such amendment, without the consent of the Holders of
all Certificates then Outstanding.

           Prior to the solicitation of consent of Certificateholders in
connection with any such amendment, the party seeking such amendment shall
furnish the Trustee with an Opinion of Counsel stating whether such amendment
would adversely affect the qualification of the Trust Fund as a REMIC and notice
of the conclusion expressed in such Opinion of Counsel shall be included with
any such solicitation. An amendment made with the consent of all
Certificateholders and executed in accordance with this Section 11.01 shall be
permitted or authorized by this Agreement notwithstanding that such Opinion of
Counsel may conclude that such amendment would adversely affect the
qualification of the Trust Fund as a REMIC.

           Promptly after the execution of any such amendment or consent the
Trustee shall furnish written notification of the substance of or a copy of such
amendment to each Certificateholder and to each Rating Agency.

           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
requirements as the Trustee may prescribe.

           SECTION 11.02. Recordation of Agreement. This Agreement is subject to
recordation in all appropriate public offices for real property records in all
the counties or other comparable jurisdictions in which any or all of the
properties subject to the Mortgages are situated, and in any other appropriate
public recording office or elsewhere, such recordation to be effected by the
Master Servicer and at its expense on direction by the Trustee, who will act at
the direction of Holders of Certificates evidencing not less than 50% of all
Voting Rights, but only upon direction of the Trustee accompanied by an Opinion
of Counsel to the effect that such recordation materially and beneficially
affects the interests of Certificateholders.


                                       85
<PAGE>   92

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

           SECTION 11.03. Limitation on Rights of Certificateholders. The death
or incapacity of any Certificateholder shall not operate to terminate this
Agreement or the Trust, nor entitle such Certificateholder's legal
representatives or heirs to claim an accounting or to take any action or
commence any proceeding in any court for a partition or winding up of the Trust,
nor otherwise affect the rights, obligations and liabilities of the parties
hereto or any of them.

           No Certificateholder shall have any right to vote (except as provided
herein) or in any manner otherwise control the operation and management of the
Trust, or the obligations of the parties hereto, nor shall anything herein set
forth, or contained in the terms of the Certificates, be construed so as to
constitute the Certificateholders from time to time as partners or members of an
association; nor shall any Certificateholder be under any liability to any third
person by reason of any action taken by the parties to this Agreement pursuant
to any provision hereof.

           No Certificateholder shall have any right by virtue or by availing
itself of any provisions of this Agreement to institute any suit, action or
proceeding in equity or at law upon or under or with respect to this Agreement,
unless such Holder previously shall have given to the Trustee a written notice
of default and of the continuance thereof, as provided herein, and unless also
the Holders of Certificates evidencing Percentage Interests aggregating not less
than 25% of each Class of Certificates affected thereby shall have made written
request upon the Trustee to institute such action, suit or proceeding in its own
name as Trustee hereunder and shall have offered to the Trustee such reasonable
indemnity as it may require against the costs, expenses and liabilities to be
incurred therein or thereby, and the Trustee, for 60 days after its receipt of
such notice, request and offer of indemnity, shall have neglected or refused to
institute any such action, suit or proceeding; it being understood and intended,
and being expressly covenanted by each Certificateholder with every other
Certificateholder and the Trustee, that no one or more Holders of Certificates
shall have any right in any manner whatever by virtue or by availing itself or
themselves of any provisions of this Agreement to affect, disturb or prejudice
the rights of the Holders of any other of the Certificates, or to obtain or seek
to obtain priority over or preference to any other such Holder, or to enforce
any right under this Agreement, except in the manner herein provided and for the
equal, ratable and common benefit of all Certificateholders. For the protection
and enforcement of the provisions of this Section 11.03, each and every
Certificateholder and the Trustee shall be entitled to such relief as can be
given either at law or in equity.

ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT APPLICATION OF THE

shall promptly request from the Certificate Registrar a current list as provided
above, and shall afford such applicants access to such list promptly upon
receipt.

           Every Certificateholder, by receiving and holding such list, agrees
with the Certificate Registrar and the Trustee that neither the Certificate
Registrar nor the Trustee shall be held accountable by reason of the disclosure
of any such information as to the names and addresses of the Certificateholders
hereunder, regardless of the source from which such information was derived.

           constitutes the valid and legally binding obligation of the Assignee
           enforceable against the Assignee in accordance with its respective

           of, of declaration, filing or registration with, any governmental
           entity is required to be obtained or made by the Assignee in

                     (d) The Assignee agrees to be bound, as "Purchaser," by all

           Mortgage Loans, and from and after the date hereof, the Assignee
           assumes, for the benefit of each of the Company and the Assignor, the
           Assignor's obligations as Purchaser thereunder.

           6. Recognition of Assignee and Assigns. From and after the date
hereof, the Company shall recognize the Assignee as the owner of the Mortgage
Loans, having the status and rights of "Purchaser" under the Sale Agreement. The
Company acknowledges that, in order to effect a securitization of the Mortgage
Loans, the Assignee intends to transfer the Mortgage Loans to a trust fund (the
"Trust Fund"). From and after the date of any such transfer, the Company shall
recognize the Trust Fund as the owner of the Mortgage Loans, having the status
and rights of "Purchaser" under the Sale Agreement. The Company further
acknowledges that such Trust Fund shall be an intended third-party beneficiary
of this Assignment and of the Sale Agreement, having the right to enforce
directly against the Company the provisions hereof and thereof.

           7. Ratification of Sale Agreement. Except as expressly set forth
herein, all terms and provisions of the Sale Agreement are hereby ratified,
affirmed and remain in full force and effect unmodified hereby.

           8. Successors and Assigns. The provisions of this Assignment shall be
binding upon and inure to the benefit of the respective successors and assigns
of the parties hereto.

           9. Counterparts. This Assignment may be executed simultaneously in
any number of counterparts. Each counterpart shall be deemed to be an original,
and all such counterparts shall constitute one and the same instrument.

           10. Governing Law. EXCEPT TO THE EXTENT PREEMPTED BY FEDERAL LAW,
THIS ASSIGNMENT SHALL BE CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF
NEW YORK AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER SHALL
BE DETERMINED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT


                                       3


<PAGE>   4

REGARD TO THE CONFLICTS OF LAWS PROVISIONS OF NEW YORK OR ANY OTHER
JURISDICTION.

           11. Amendment. This Agreement may be amended from time to time by
written agreement signed by the parties hereto.

           12. Survival. This Assignment shall survive the conveyance of the
Mortgage Loans and the assignment of the Sale Agreement by (a) the Assignor to
the Assignee and (b) by the Assignee to the Trust Fund as contemplated in
Section 6 above.

           13. Intention of the Parties. It is the intention of the parties that
the Assignee is purchasing, and the Assignor is selling, the Mortgage Loans and
not a debt instrument of the Assignor or another security. Accordingly, the
parties hereto each intend to treat the transaction for federal income tax
purposes as a sale by the Assignor, and a purchase by the Assignee, of the
Mortgage Loans.

           It is not the intention of the parties that such conveyances be
deemed a pledge thereof. However, in the event that, notwithstanding the intent
of the parties, such assets are held to be the property of the Assignor or if
for any other reason this Agreement is held or deemed to create a security
interest in either such assets, then (i) this Agreement shall be deemed to be a
security agreement within the meaning of the Uniform Commercial Code of the
State of New York and (ii) the conveyances provided for in this Agreement shall
be deemed to be an assignment and a grant by the Assignor to the Assignee of a
security interest in all of the assets transferred, whether now owned or
hereafter acquired.
