                          CONVEYANCE OF MORTGAGE LOANS;
                         REPRESENTATIONS AND WARRANTIES

            SECTION 2.01. Conveyance of Mortgage Loans.

            (a) The Seller, concurrently with the execution and delivery hereof,
hereby sells, transfers, assigns, sets over and otherwise conveys to the
Depositor, without recourse, all the right, title and interest of the Seller in

to the Closing Date, the Seller shall deliver to the Depositor or, at the
Depositor's direction, to the Trustee or other designee of the Depositor, the
Mortgage File for each Mortgage Loan listed in the Mortgage Loan Schedule. Such
delivery of the Mortgage Files shall be made against payment by the Depositor of
the purchase price, previously agreed to by the Seller and Depositor, for the
Mortgage Loans. With respect to any Mortgage Loan that does not have a first
payment date on or before the Due Date in the month of the first Distribution
Date, the Seller shall deposit into the Distribution Account on or before the
Distribution Account Deposit Date relating to the first Distribution Date, an
amount equal to one month's interest at the related Adjusted Mortgage Rate on
the Cut-off Date Principal Balance of such Mortgage Loan.

            (b) The Depositor, concurrently with the execution and delivery
hereof, hereby sells, transfers, assigns, sets over and otherwise conveys to the
Trustee for the benefit of the Certificateholders, without recourse, all the
right, title and interest of the Depositor in and to the Trust Fund together
with the Depositor's right to require the Seller to cure any breach of a
representation or warranty made herein by the Seller or to repurchase or
substitute for any affected Mortgage Loan in accordance herewith.

            (c) In connection with the transfer and assignment set forth in
clause (b) above, the Depositor has delivered or caused to be delivered to the
Trustee for the benefit of the Certificateholders the following documents or
instruments with respect to each Mortgage Loan so assigned:

                  (i) the original Mortgage Note endorsed by manual or facsimile
            signature in blank in the following form: "Pay to the order of
            ____________ without recourse," with all intervening endorsements
            showing a complete chain of endorsement from the originator to the
            Seller (each such endorsement being sufficient to transfer all
            right, title and interest of the party so endorsing, as noteholder
            or assignee thereof, in and to that Mortgage Note);

                  (ii) except as provided below, within 45 days after the
            Closing Date the original recorded Mortgage or a copy of such
            Mortgage certified by the Seller as being a true and complete copy
            of the Mortgage;

                  (iii) a duly executed assignment of the Mortgage (which may be
            included in a blanket assignment or assignments), together with,
            except as provided below, within 45 days after the Closing Date all
            interim recorded assignments of such 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 


                                       30
<PAGE>   36

            Mortgage to which the assignment relates) sufficient to show a
            complete chain of assignment from the originator to the Seller;
            provided that, if the related Mortgage has not been returned from
            the applicable public recording office, such assignment of the
            Mortgage may exclude the information to be provided by the recording
            office;

                  (iv) the original or copies of each assumption, modification,
            written assurance or substitution agreement, if any;

                  (v) except as provided below, within 45 days after the Closing
            Date the original or duplicate original lender's title policy and
            all riders thereto; and

                  (vi) in the case of a Cooperative Loan, the originals of the
            following documents or instruments:

                        (a) The Coop Shares, together with a stock power in
                  blank;

                        (b) The executed Security Agreement;

                        (c) The executed Proprietary Lease;

                        (d) The executed Recognition Agreement;

                        (e) The executed assignment of Recognition Agreement;

                        (f) The executed UCC-1 financing statement with evidence
                  of recording thereon which have been filed in all places
                  required to perfect the Seller's interest in the Coop Shares
                  and the Proprietary Lease; and

                        (g) Executed UCC-3 financing statements or other
                  appropriate UCC financing statements required by state law,
                  evidencing a complete and unbroken line from the mortgagee to
                  the Trustee with evidence of recording thereon (or in a form
                  suitable for recordation).

            In the event that in connection with any Mortgage Loan the Depositor
cannot deliver (a) the original recorded Mortgage, (b) all interim recorded
assignments or (c) the lender's title policy (together with all riders thereto)
satisfying the requirements of clause (ii), (iii) or (v) above, respectively,
because such document or documents have not been returned from the applicable
public recording office in the case of clause (ii) or (iii) above, or because
the title policy has not been delivered to either the Master Servicer or the
Depositor by the applicable title insurer in the case of clause (v) above, the
Depositor shall promptly deliver to the Trustee, in the case of clause (ii) or
(iii) above, such original Mortgage or such interim assignment, as the case may
be, with evidence of recording indicated thereon upon receipt thereof from the
public recording office, or a copy thereof, certified, if appropriate, by the
relevant recording office, but in no event shall any such delivery of the
original Mortgage and each such interim assignment or a copy thereof, certified,
if appropriate, by the relevant recording office, be made later than one year
following the Closing Date, or, in the case of clause (v) above, no later than
120 days following the Closing Date; provided, however, in the event the
Depositor is unable to deliver by such date each Mortgage and each such interim
assignment by reason of the fact that any such documents have not been returned
by the appropriate recording office, or, in the case of each such interim
assignment, because the related Mortgage has not been returned by the
appropriate recording office, the 


                                       31
<PAGE>   37

Depositor shall deliver such documents to the Trustee as promptly as possible
upon receipt thereof and, in any event, within 720 days following the Closing
Date. The Depositor shall forward or cause to be forwarded to the Trustee (a)
from time to time additional original documents evidencing an assumption or
modification of a Mortgage Loan and (b) any other documents required to be
delivered by the Depositor or the Master Servicer to the Trustee. In the event
that the original Mortgage is not delivered and in connection with the payment
in full of the related Mortgage Loan and 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
execute and deliver or cause to be executed and delivered such a document to the
public recording office. In the case where a public recording office retains the
original recorded Mortgage or in the case where a Mortgage is lost after
recordation in a public recording office, the Seller shall deliver to the
Trustee a copy of such Mortgage certified by such public recording office to be
a true and complete copy of the original recorded Mortgage.

            As promptly as practicable subsequent to such transfer and
assignment, and in any event, within thirty (30) days thereafter, the Master
Servicer shall (i) affix the Trustee's name to each assignment of Mortgage, as
the assignee thereof, (ii) cause such assignment to be in proper form for
recording in the appropriate public office for real property records and (iii)
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 assignments of 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 practicable after receipt of such information and
in any event within thirty (30) days after receipt thereof and that the Master
Servicer need not cause to be recorded any assignment which relates to a
Mortgage Loan (a) the Mortgaged Property and Mortgage File relating to which are
located in California or (b) in any other jurisdiction under the laws of which,
as evidenced by an Opinion of Counsel delivered by the Seller (at the Seller's
expense) to the Trustee, the recordation of such assignment is not necessary to
protect the Trustee's and the Certificateholders' interest in the related
Mortgage Loan.

            In the case of Mortgage Loans that have been prepaid in full as of
the Closing Date, the Depositor, in lieu of delivering the above documents to
the Trustee, will deposit in the Certificate Account the portion of such payment
that is required to be deposited in the Certificate Account pursuant to Section
3.05 hereof.

            SECTION 2.02. Acceptance by Trustee of the Mortgage Loans.

            The Trustee acknowledges receipt of the documents identified in the
Initial Certification in the form annexed hereto as Exhibit G and declares that
it holds and will hold such documents and the other documents delivered to it
constituting the Mortgage Files, and that it holds or will hold such other
assets as are included in the Trust Fund, in trust for the exclusive use and
benefit of all present and future Certificateholders. The Trustee acknowledges
that it will maintain possession of the Mortgage Notes in the State of
California or the State of New York, unless otherwise permitted by the Rating
Agencies.

            The Trustee agrees to execute and deliver on the Closing Date to the
Depositor, the Master Servicer and the Seller an Initial Certification in the
form annexed hereto as Exhibit G. Based on its review and examination, and only
as to the documents identified in such Initial Certification, the Trustee
acknowledges that such documents appear regular on their face and relate to such
Mortgage Loan. The Trustee shall be under no duty or obligation to inspect,
review or examine said documents, instruments, certificates or other papers to
determine that the same are genuine, enforceable or 


                                       32
<PAGE>   38

appropriate for the represented purpose or that they have actually been recorded
in the real estate records or that they are other than what they purport to be
on their face.

            Not later than 90 days after the Closing Date, the Trustee shall
deliver to the Depositor, the Master Servicer and the Seller a Final
Certification in the form annexed hereto as Exhibit H, with any applicable
exceptions noted thereon.

            If, in the course of such review, the Trustee finds any document
constituting a part of a Mortgage File which does not meet the requirements of
Section 2.01, the Trustee shall list such as an exception in the Final
Certification; provided, however that the Trustee shall not make any
determination as to whether (i) any endorsement is sufficient to transfer all
right, title and interest of the party so endorsing, as noteholder or assignee
thereof, in and to that Mortgage Note or (ii) any assignment is in recordable
form or is sufficient to effect the assignment of and transfer to the assignee
thereof under the mortgage to which the assignment relates. The Seller shall
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 Seller shall either (a) substitute for the related
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, or (b) purchase such Mortgage Loan from the Trustee within 90 days from
the date the Seller was notified of such defect in writing at the Purchase Price
of such Mortgage Loan; provided, however, that in no event shall such
substitution or purchase occur more than 540 days from the Closing Date, except
that if the substitution or purchase of a Mortgage Loan pursuant to this
provision is required by reason of a delay in delivery of any documents by the
appropriate recording office, and there is a dispute between either the Master
Servicer or the Seller and the Trustee over the location or status of the
recorded document, then such substitution or purchase shall occur within 720
days from the Closing Date. The Trustee shall deliver written notice to each
Rating Agency within 270 days from the Closing Date indicating each Mortgage
Loan (a) which has not been returned by the appropriate recording office or (b)
as to which there is a dispute as to location or status of such Mortgage Loan.
Such notice shall be delivered every 90 days thereafter until the related
Mortgage Loan is returned to the Trustee. Any such substitution pursuant to (a)
above or purchase pursuant to (b) above shall not be effected prior to the
delivery to the Trustee of the Opinion of Counsel required by Section 2.05
hereof, if any, and any substitution pursuant to (a) above shall not be effected
prior to the additional delivery to the Trustee of a Request for Release
substantially in the form of Exhibit N. No substitution is permitted to be made
in any calendar month after the Determination Date for such month. The Purchase
Price for any such Mortgage Loan shall be deposited by the Seller in the
Certificate Account on or prior to the Distribution Account Deposit Date for the
Distribution Date in the month following the month of repurchase and, upon
receipt of such deposit and certification with respect thereto in the form of
Exhibit N hereto, the Trustee shall release the related Mortgage File to the
Seller and shall execute and deliver at the Seller's request such instruments of
transfer or assignment prepared by the Seller, in each case without recourse, as
shall be necessary to vest in the Seller, or a designee, the Trustee's interest
in any Mortgage Loan released pursuant hereto.

            The Trustee shall 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 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.


                                       33
<PAGE>   39

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

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

            (a) Mellon Mortgage Company, in its capacities as Seller and Master
Servicer, hereby makes the representations and warranties set forth in Schedule
II hereto, and by this reference incorporated herein, to the Depositor and the
Trustee, as of the Closing Date, or if so specified therein, as of the Cut-off
Date.

            (b) The Seller, in its capacity as Seller, hereby makes the
representations and warranties set forth in Schedule III hereto, and by this
reference incorporated herein, to the Depositor and the Trustee, as of the
Closing Date, or if so specified therein, as of the Cut-off Date.

            (c) Upon discovery by any of the parties hereto of a breach of a
representation or warranty made pursuant to Section 2.03(b) that materially and
adversely affects the interests of the Certificateholders in any Mortgage Loan,
the party discovering such breach shall give prompt notice thereof to the other
parties. The Seller hereby covenants that 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 Section 2.03(b) which materially and
adversely affects the interests of the Certificateholders in any Mortgage Loan,
it shall cure such breach in all material respects, and if such breach is not so
cured, shall, (i) if such 90-day period expires prior to the second anniversary
of the Closing Date, remove such Mortgage Loan (a "Deleted 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; or (ii)
repurchase the affected Mortgage Loan or Mortgage Loans from the Trustee at the
Purchase Price in the manner set forth below; provided, however, that any such
substitution pursuant to (i) above shall not be effected prior to the delivery
to the Trustee of the Opinion of Counsel required by Section 2.05 hereof, if
any, and any such substitution pursuant to (i) above shall not be effected prior
to the additional delivery to the Trustee of a Request for Release substantially
in the form of Exhibit N and the Mortgage File for any such Substitute Mortgage
Loan. The Seller shall promptly reimburse the Master Servicer and the Trustee
for any expenses reasonably incurred by the Master Servicer or the Trustee in
respect of enforcing the remedies for such breach. With respect to the
representations and warranties described in this Section which are made to the
best of the Seller's knowledge, if it is discovered by either the Depositor, the
Seller or the Trustee that the substance of such representation and warranty is
inaccurate and such inaccuracy materially and adversely affects the value of the
related Mortgage Loan or the interests of the Certificateholders therein,
notwithstanding the Seller's lack of knowledge with respect to the substance of
such representation or warranty, such inaccuracy shall be deemed a breach of the
applicable representation or warranty.

            With respect to any Substitute Mortgage Loan or Loans, the Seller
shall deliver to the Trustee for the benefit of the Certificateholders the
Mortgage Note, the Mortgage, the related assignment of the Mortgage, and such
other documents and agreements as are 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. Scheduled Payments due with respect to
Substitute Mortgage Loans in the month of substitution shall not be part of the
Trust Fund and will be retained by the Seller on the next succeeding
Distribution Date. For the 


                                       34
<PAGE>   40

month of substitution, distributions to Certificateholders will include the
monthly payment due on any Deleted Mortgage Loan for such month and thereafter
the Seller shall be entitled to retain all amounts received in respect of such
Deleted Mortgage Loan. The Master Servicer shall amend the Mortgage Loan
Schedule for the benefit of the Certificateholders to reflect the removal of
such Deleted 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. Upon such substitution, the Substitute Mortgage Loan or
Loans shall be subject to-the terms of this Agreement in all respects, and the
Seller shall be deemed to have made with respect to such Substitute Mortgage
Loan or Loans, as of the date of substitution, the representations and
warranties made pursuant to Section 2.03(b) with respect to such Mortgage Loan.
Upon any such substitution and the deposit to the Certificate Account of the
amount required to be deposited therein in connection with such substitution as
described in the following paragraph, the Trustee shall release the Mortgage
File held for the benefit of the Certificateholders relating to such Deleted
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 Deleted Mortgage Loan substituted
for pursuant to this Section 2.03.

            For any month in which the Seller substitutes one or more Substitute
Mortgage Loans for one or more Deleted Mortgage Loans, the Master Servicer will
determine the amount (if any) by which the aggregate principal balance of all
such Substitute Mortgage Loans as of the date of substitution is less than the
aggregate Stated Principal Balance of all such Deleted Mortgage Loans (after
application of the scheduled 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 Deleted Mortgage Loans shall be deposited in the
Certificate Account by the Seller on or before the Distribution Account Deposit
Date for the Distribution Date in the month succeeding the calendar month during
which the related Mortgage Loan became required to be purchased or replaced
hereunder.

            In the event that the Seller shall have repurchased a Mortgage Loan,
the Purchase Price therefor shall be deposited in the Certificate Account
pursuant to Section 3.05 on or before the Distribution Account Deposit Date for
the Distribution Date in the month following the month during which the Seller
became obligated hereunder to repurchase or replace such Mortgage Loan and upon
such deposit of the Purchase Price, the delivery of the Opinion of Counsel
required by Section 2.05 and receipt of a Request for Release in the form of
Exhibit N hereto, the Trustee shall release the related Mortgage File held for
the benefit of the Certificateholders to such Person, and the Trustee shall
execute and deliver at such Person's direction such instruments of transfer or
assignment prepared by such Person, in each case without recourse, as shall be
necessary to transfer title from the Trustee. It is understood and agreed that
the obligation under this Agreement of any Person to cure, repurchase or replace
any Mortgage Loan as to which a breach has occurred and is continuing shall
constitute the sole remedy against such Persons respecting such breach available
to Certificateholders, the Depositor or the Trustee on their behalf.

            The representations and warranties made 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 Depositor as to
                          the Mortgage Loans.

            The Depositor 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 Depositor had good title to the Mortgage Loans
and the Mortgage Notes were subject to no offsets, defenses or counterclaims
arising from the action or inaction of the Depositor.

            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 Depositor or the Trustee of a breach of any
of the foregoing representations and warranties set forth in this Section 2.04
(referred to herein as a "breach"), which breach materially and adversely
affects the interest of the Certificateholders, the party discovering such
breach shall give prompt written notice to the others and to each Rating Agency.

            SECTION 2.05. Delivery of Opinion of Counsel in Connection with
                          Substitutions.

            (a) Notwithstanding any contrary provision of this Agreement, no
substitution pursuant to Section 2.02 or Section 2.03 shall be made more than 90
days after the Closing Date unless the Seller delivers to the Trustee an Opinion
of Counsel, which Opinion of Counsel shall not be at the expense of either the
Trustee or the Trust Fund, addressed to the Trustee, to the effect that such
substitution will not (i) result in the imposition of the tax on "prohibited
transactions" on the Trust Fund or contributions after the Startup Date, as
defined in Sections 860F(a)(2) and 860G(d) of the Code, respectively, or (ii)
cause the Trust Fund to fail to qualify as a REMIC at any time that any
Certificates are outstanding.

            (b) Upon discovery by the Depositor, 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 (5) Business
Days of discovery) give written notice thereof to the other parties. In
connection therewith, the Trustee shall require the Seller, at the Seller's
option, to either (i) 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 (ii) repurchase 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 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 repurchased for breach of a representation or warranty contained in Section
2.03.

            SECTION 2.06. Execution and Delivery of Certificates.

            The Trustee acknowledges the transfer and assignment to it of the
Trust Fund and, concurrently with such transfer and assignment, has executed and
delivered to or upon the order of the Depositor, the Certificates in authorized
denominations evidencing directly or indirectly the entire ownership of the
Trust Fund. 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 best
of its ability, 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 accordance with the terms of
this Agreement and customary and usual standards of practice of prudent mortgage
loan servicers. In connection with such servicing and administration, the Master
Servicer shall have full power and authority, acting alone and/or through
Subservicers as provided in Section 3.02 hereof, 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 (i) to execute and deliver, on behalf of
the Certificateholders and the Trustee, customary consents or waivers and other
instruments and documents, (ii) 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), (iii) to collect any Insurance
Proceeds and other Liquidation Proceeds, and (iv) to effectuate foreclosure or
other conversion of the ownership of the Mortgaged Property securing any
Mortgage Loan; provided that the Master Servicer shall not take any action that
is inconsistent with or prejudices the interests of the Trust Fund or the
Certificateholders in any Mortgage Loan or the rights and interests of the
Depositor, the Trustee and the Certificateholders under this Agreement. The
Master Servicer shall represent and protect the interests of the Trust Fund 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 Mortgage
Loan which would cause the Trust Fund to fail to qualify as a REMIC or result in
the imposition of any tax under Section 860F(a) or Section 860G(d) of the Code.
Without limiting the generality of the foregoing, the Master Servicer, in its
own name or in the name of the Depositor and the Trustee, is hereby authorized
and empowered by the Depositor and the Trustee, when the Master Servicer
believes it appropriate in its reasonable judgment, to execute and deliver, on
behalf of the Trustee, the Depositor, 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 Depositor 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
Depositor and/or the Trustee shall execute such documents and deliver them to
the Master Servicer.


                                       37
<PAGE>   43

            In accordance with the standards of the preceding paragraph, the
Master Servicer shall advance or cause to be advanced funds as necessary for the
purpose of effecting the payment of taxes and assessments on the Mortgaged
Properties, which advances shall be reimbursable in the first instance from
related collections from the Mortgagors pursuant to Section 3.06, and further as
provided in Section 3.08. 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.

            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 Subservicer pursuant to a subservicing agreement; provided,
however, that such subservicing arrangement and the terms of the related
subservicing agreement must provide for the servicing of such Mortgage Loans in
a manner consistent with the servicing arrangements contemplated hereunder.
Unless the context otherwise requires, references in this Agreement to actions
taken or to be taken by the Master Servicer in servicing the Mortgage Loans
include actions taken or to be taken by a Subservicer on behalf of the Master
Servicer. Notwithstanding the provisions of any subservicing agreement, any of
the provisions of this Agreement relating to agreements or arrangements between
the Master Servicer and a Subservicer or reference to actions taken through a
Subservicer or otherwise, the Master Servicer shall remain obligated and liable
to the Depositor, 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
subservicing agreements or arrangements or by virtue of indemnification from the
Subservicer 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 Subservicer performed pursuant to the related subservicing
agreement shall be performed as an 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 Subservicer regardless of whether such
payments are remitted by the Subservicer to the Master Servicer.

            SECTION 3.03. Rights of the Depositor and the Trustee in Respect of
                          the Master Servicer.

            The Depositor 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 Depositor or its designee. Neither the Trustee nor the
Depositor shall have any responsibility or liability for any action or failure
to act by the Master Servicer nor shall the Trustee or the Depositor be
obligated to supervise the performance of the Master Servicer hereunder or
otherwise.

            SECTION 3.04. Trustee to Act as Master Servicer.

            In the event that the Master Servicer shall for any reason no longer
be the Master Servicer hereunder (including by reason of an Event of Default),
the Trustee or its successor shall thereupon assume all of the rights and
obligations of the Master Servicer hereunder arising thereafter (except that the
Trustee shall not be (i) liable for losses of the Master Servicer pursuant to
Section 3.09 hereof or any acts or omissions of the predecessor Master Servicer
hereunder, (ii) obligated to make Advances if it is prohibited from doing so by
applicable law, (iii) obligated to effectuate repurchases or substitutions of
Mortgage Loans hereunder including, but not limited to, repurchases or
substitutions of Mortgage Loans pursuant to Section 2.02 or 2.03 hereof, (iv)
responsible for expenses of the Master Servicer pursuant to Section 2.03 or (v)
deemed to have made any representations and warranties of the Master Servicer
hereunder). Any such assumption shall be subject to Section 7.02 hereof. Each
subservicing agreement shall provide that 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 its successor may, at its option, succeed to any rights
and obligations of the Master Servicer under each subservicing 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 subservicing agreement or substitute subservicing
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 the substitute subservicing
agreement to the assuming party.

            SECTION 3.05. Collection of Mortgage Loan Payments; Certificate
                          Account; Distribution Account.

            (a) The Master Servicer shall make reasonable efforts in accordance
with the customary and usual standards of practice of prudent mortgage servicers
to collect all payments called for under the terms and provisions of the
Mortgage Loans to the extent such procedures shall be consistent with this
Agreement and the terms and provisions of any related Required Insurance Policy.
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 180 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 Advances on the related Mortgage
Loan in accordance with the provisions of Section 4.01 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 a Certificate
Account into which the Master Servicer shall deposit or cause to be deposited on
a daily basis within two Business Days of receipt, except as otherwise
specifically provided herein, the following payments and collections remitted by
Subservicers 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:


                                       39
<PAGE>   45

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

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

            (iii) all Insurance Proceeds and Liquidation Proceeds, other than
      proceeds to be applied to the restoration or repair of the Mortgaged
      Property or released to the Mortgagor in accordance with the Master
      Servicer's normal servicing procedures;

            (iv) any amount required to be deposited by the Master Servicer
      pursuant to Section 3.05(e) in connection with any losses on Permitted
      Investments;

            (v) any amounts required to be deposited by the Master Servicer
      pursuant to Section 3.09(b), 3.09(d), and in respect of net monthly rental
      income from REO Property pursuant to Section 3.11 hereof;

            (vi) all Substitution Adjustment Amounts;

            (vii) all Advances made by the Master Servicer pursuant to Section
      4.01; and

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

            In addition, with respect to any Mortgage Loan that is subject to a
buydown agreement, on each Due Date for such Mortgage Loan, in addition to the
monthly payment remitted by the Mortgagor, the Master Servicer shall cause funds
to be deposited into the Certificate Account in an amount required to cause an
amount of interest to be paid with respect to such Mortgage Loan equal to the
amount of interest that has accrued on such Mortgage Loan from the preceding Due
Date at the Mortgage Rate net of the related Master Servicing Fee on such date.

            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 Certificate Account to withdraw such amount from the
Certificate Account, any provision herein to the contrary notwithstanding. Such
withdrawal or direction may be accomplished by delivering written notice thereof
to the Trustee or such other institution maintaining the Certificate Account
which describes the amounts deposited in error in the Certificate Account. The
Master Servicer shall maintain adequate records with respect to all withdrawals
made pursuant to this Section. All funds deposited in the Certificate Account
shall be held in trust for the Certificateholders until withdrawn in accordance
with Section 3.08.

            (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:

            (ix) the aggregate amount remitted by the Master Servicer to the
      Trustee pursuant to Section 3.08(a)(ix);


                                       40
<PAGE>   46

            (x) any amount deposited by the Master Servicer pursuant to Section
      3.05(d) in connection with any losses on Permitted Investments; and

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

            In the event that 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 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 3.08. 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 Certificate Account or the
Distribution Account is maintained shall invest the funds therein as directed in
writing by the Master Servicer in Permitted Investments, which shall mature not
later than (i) in the case of the Certificate Account, the second 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 the
Business Day next preceding 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 fund or 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 Certificate Account or the Distribution
Account shall be for the benefit of the Master Servicer as servicing
compensation and shall be remitted to it monthly as provided herein. The amount
of any realized losses in the Certificate 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 Certificate Account or paid to the
Trustee for deposit into the Distribution Account, as applicable.

            (e) The Master Servicer shall give notice to the Trustee, the
Seller, each Rating Agency and the Depositor of any proposed change of the
location of the Certificate Account prior to any change thereof. The Trustee
shall give notice to the Master Servicer, the Seller, each Rating Agency and the
Depositor of any proposed change of the location of the Distribution Account
prior to any change thereof.

            SECTION 3.06. 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 establish and maintain one
or more accounts (each, an "Escrow Account") and deposit and retain therein all
collections from the Mortgagors (or advances by the Master Servicer) for the
payment of taxes, assessments, hazard insurance premiums or comparable items for
the account of the Mortgagors. Nothing herein shall require the Master Servicer
to compel a Mortgagor to establish an Escrow Account in violation of applicable
law.


                                       41
<PAGE>   47

            (b) Withdrawals of amounts so collected from the Escrow Accounts may
be made only to effect timely payment of taxes, assessments, hazard insurance
premiums, condominium or PUD association dues, or comparable items, to reimburse
the Master Servicer out of related collections for any payments made pursuant to
Sections 3.01 hereof (with respect to taxes and assessments and insurance
premiums) and 3.09 hereof (with respect to hazard insurance), to refund to any
Mortgagors any sums determined to be overages, to pay interest, if required by
law or the terms of the related Mortgage or Mortgage Note, to Mortgagors on
balances in the Escrow Account or to clear and terminate the Escrow Account at
the termination of this Agreement in accordance with Section 9.01 hereof. The
Escrow Accounts shall not be a part of the Trust Fund.

            (c) The Master Servicer shall advance any payments referred to in
Section 3.06(a) that are not timely paid by the Mortgagors on the date when the
tax, premium or other cost for which such payment is intended is due, but the
Master Servicer shall be required so to advance only to the extent that such
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 3.07. Access to Certain Documentation and Information
                          Regarding the Mortgage Loans.

            The Master Servicer shall afford the Depositor and 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 3.08. Permitted Withdrawals from the Certificate Account and
                          Distribution Account.

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

            (i) to pay to the Master Servicer (to the extent not previously
      retained by the Master Servicer) the servicing compensation to which it is
      entitled pursuant to Section 3.14, and to pay to the Master Servicer, as
      additional servicing compensation, earnings on or investment income with
      respect to funds in or credited to the Certificate Account;

            (ii) to reimburse the Master Servicer for unreimbursed Advances made
      by it, such right of reimbursement pursuant to this subclause (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;


                                       42
<PAGE>   48

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

            (v) to reimburse the Master Servicer for (a) unreimbursed Servicing
      Advances, the Master Servicer's right to reimbursement pursuant to this
      clause (a) with respect to any Mortgage Loan being limited to amounts
      received on such Mortgage Loan(s) which represent late recoveries of the
      payments for which such advances were made pursuant to Section 3.01 or
      Section 3.06 and (b) for unpaid Master Servicing Fees as provided in
      Section 3.11 hereof;

            (vi) to pay to the purchaser, with respect to each Mortgage Loan or
      property acquired in respect thereof that has been purchased pursuant to
      Section 2.02, 2.03 or 3.11, all amounts received thereon after the date of
      such purchase;

            (vii) to reimburse the Seller, the Master Servicer or the Depositor
      for expenses incurred by any of them and reimbursable pursuant to Section
      6.03 hereof;

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

            (ix) on or prior to the Distribution Account Deposit Date, to
      withdraw an amount equal to the Available Funds for each Loan Group for
      such Distribution Date and remit such amount to the Trustee for deposit in
      the Distribution Account; and

            (x) to clear and terminate the Certificate Account upon termination
      of this Agreement pursuant to Section 9.01 hereof.

            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 Certificate Account pursuant to such subclauses (i), (ii),
(iv), (v) and (vi). Prior to making any withdrawal from the Certificate Account
pursuant to subclause (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 Loans(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 (and to withhold and pay from the amounts so withdrawn, the amount of
any taxes that it is authorized to withhold pursuant to the last paragraph of
Section 8.11). In addition, the Trustee may from time to time make withdrawals
from the Distribution Account for the following purposes:

            (i) [reserved];

            (ii) to pay to the Master Servicer as additional servicing
      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


                                       43
<PAGE>   49

            (iv) to clear and terminate the Distribution Account upon
      termination of the Agreement pursuant to Section 9.01 hereof.

            SECTION 3.09. Maintenance of Hazard Insurance; Maintenance of
                          Primary Insurance Policies.

            (a) The Master Servicer shall cause to be maintained, for each
Mortgage Loan, hazard insurance with extended coverage in an amount that is at
least equal to the lesser of (i) the maximum insurable value of the improvements
securing such Mortgage Loan or (ii) the greater of (y) the outstanding principal
balance of the Mortgage Loan and (z) an amount such that the proceeds of such
policy shall be sufficient to prevent the Mortgagor and/or the mortgagee from
becoming a co-insurer. Each such policy of standard hazard insurance shall
contain, or have an accompanying endorsement that contains, a standard mortgagee
clause. Any amounts collected by the Master Servicer under any such policies
(other than the amounts to be applied to the restoration or repair of the
related Mortgaged Property or amounts released to the Mortgagor in accordance
with the Master Servicer's normal servicing procedures) shall be deposited in
the Certificate Account. Any cost incurred by the Master Servicer in maintaining
any such insurance shall not, for the purpose of calculating monthly
distributions to the Certificateholders or remittances to the Trustee for their
benefit, be added to the principal balance of the Mortgage Loan, notwithstanding
that the terms of the Mortgage Loan so permit. Such costs shall be recoverable
by the Master Servicer out of late payments by the related Mortgagor or out of
Liquidation Proceeds to the extent permitted by Section 3.08 hereof. It is
understood and agreed that no earthquake or other additional insurance is to be
required of any Mortgagor or maintained on property acquired in respect of a
Mortgage other than pursuant to such applicable laws and regulations as shall at
any time be in force and as shall require such additional insurance. If the
Mortgaged Property is located at the time of origination of the Mortgage Loan in
a federally designated special flood hazard area and such area is participating
in the national flood insurance program, the Master Servicer shall cause flood
insurance to be maintained with respect to such Mortgage Loan. Such flood
insurance shall be in an amount equal to the least of (i) the original principal
balance of the related Mortgage Loan, (ii) the replacement value of the
improvements which are part of such Mortgaged Property, and (iii) the maximum
amount of such insurance available for the related Mortgaged Property under the
national flood insurance program.

            (b) In the event that the Master Servicer shall obtain and maintain
a blanket policy insuring against hazard losses on all of the Mortgage Loans, it
shall conclusively be deemed to have satisfied its obligations as set forth in
the first sentence of this Section, it being understood and agreed that such
policy may contain a deductible clause on terms substantially equivalent to
those commercially available and maintained by comparable servicers. If such
policy contains a deductible clause, the Master Servicer shall, in the event
that there shall not have been maintained on the related Mortgaged Property a
policy complying with the first sentence of Section 3.09(a), and there shall
have been a loss that would have been covered by such policy, deposit in the
Certificate Account the amount not otherwise payable under the blanket policy
because of such deductible clause. In connection with its activities as Master
Servicer of the Mortgage Loans, the Master Servicer agrees to present, on behalf
of itself, the Depositor, and the Trustee for the benefit of the
Certificateholders, claims under any such blanket policy.

            (c) The Master Servicer shall not take any action which would result
in non-coverage under any applicable Primary Insurance Policy of any loss which,
but for the actions of the Master Servicer, would have been covered thereunder.
The Master Servicer shall not cancel or refuse to 


                                       44
<PAGE>   50

renew any such Primary Insurance Policy that is in effect at the date of the
initial issuance of the Certificates and is required to be kept in force
hereunder unless the replacement Primary Insurance Policy for such canceled or
non-renewed policy is maintained with a Qualified Insurer. The Master Servicer
shall not be required to maintain any Primary Insurance Policy (i) with respect
to any Mortgage Loan with a Loan-to-Value Ratio less than or equal to 80% as of
any date of determination or, based on a new appraisal, the principal balance of
such Mortgage Loan represents 80% or less of the new appraised value or (ii) if
maintaining such Primary Insurance Policy is prohibited by applicable law. The
Master Servicer agrees to effect the timely payment of the premiums on each
Primary Insurance Policy, and such costs not otherwise recoverable shall be
recoverable by the Master Servicer from the related liquidation proceeds.

            (d) In connection with its activities as Master Servicer of the
Mortgage Loans, the Master Servicer agrees to present on behalf of itself, the
Trustee and Certificateholders, claims to the insurer under any Primary
Insurance Policies and, in this regard, to take such reasonable action as shall
be necessary to permit recovery under any Primary Insurance Policies respecting
defaulted Mortgage Loans. Any amounts collected by the Master Servicer under any
Primary Insurance Policies shall be deposited in the Certificate Account.

            SECTION 3.10. Enforcement of Due-on-Sale Clauses; Assumption
                          Agreements.

            (a) Except as otherwise provided in this Section, when any property
subject to a Mortgage has been conveyed by the Mortgagor, the Master Servicer
shall to the extent that it has knowledge of such conveyance, 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 so required under such
Mortgage Note or Mortgage as a condition to such transfer. In the event that the
Master Servicer is prohibited by law from enforcing any such due-on-sale clause,
or if coverage under any Required Insurance Policy would be adversely affected,
or if nonenforcement is otherwise permitted hereunder, the Master Servicer is
authorized, subject to Section 3.10(b), to take or enter into an assumption and
modification agreement from or with the person to whom such property has been or
is about to be conveyed, pursuant to which such person becomes liable under the
Mortgage Note and, unless 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 into such agreement) by
the applicable Required Insurance Policies. The Master Servicer, subject to
Section 3.10(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 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 3.10(a) hereof, 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 


                                       45
<PAGE>   51

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 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 in connection therewith. The Master Servicer shall
notify the Trustee that any such substitution or assumption agreement has been
completed by forwarding to the Trustee 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 will be
retained by the Master Servicer as additional servicing compensation.

            SECTION 3.11. Realization Upon Defaulted Mortgage Loans; Repurchase
                          of Certain Mortgage Loans.

            The Master Servicer shall use reasonable efforts to foreclose upon
or otherwise comparably convert the ownership of properties securing such of the
Mortgage Loans as come into and continue in default and as to which no
satisfactory arrangements can be made for collection of delinquent payments. In
connection with such foreclosure or other conversion, the Master Servicer shall
follow such practices and procedures as it shall deem necessary or advisable and
as shall be normal and usual in its general mortgage servicing activities and
meet the requirements of the insurer under any Required Insurance Policy;
provided, however, that the Master Servicer may enter into, and shall give the
Rating Agencies notice of, a special servicing agreement with an unaffiliated
holder of 100% Percentage Interest of one or more Classes of Subordinated
Certificates or a holder of a class of securities representing interests in one
or more Classes of Subordinated Certificates and provided, further, that
entering into such special servicing agreement shall not result in the
downgrading or withdrawal of the respective ratings when assigned to the
Certificates. Any such agreement may contain provisions whereby such holder may
instruct the Master Servicer to commence or delay foreclosure proceedings with
respect to delinquent Mortgage Loans and will contain provisions for the deposit
of cash by the holder that would be available for distribution to
Certificateholders if Liquidation Proceeds are less than they otherwise may have
been had the Master Servicer acted in accordance with its normal procedures.
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 property unless it shall determine (i) that such restoration
and/or foreclosure will increase the proceeds of liquidation of the Mortgage
Loan after reimbursement to itself of such expenses and (ii) that such expenses
will be recoverable to it through Liquidation Proceeds (respecting which it
shall have priority for purposes of withdrawals from the Certificate Account).
The Master Servicer shall be responsible for all other costs and expenses
incurred by it in any such proceedings; provided, however, that it shall be
entitled to reimbursement thereof from the liquidation proceeds with respect to
the related Mortgaged Property, as provided in the 


                                       46
<PAGE>   52

definition of Liquidation Proceeds. If the Master Servicer has knowledge that a
Mortgaged Property which the Master Servicer is contemplating acquiring in
foreclosure or by deed in lieu of foreclosure is located within a 1 mile radius
of any site listed in the Expenditure Plan for the Hazardous Substance Clean Up
Bond Act of 1984 or other site with environmental or hazardous waste risks known
to the Master Servicer, the Master Servicer will, prior to acquiring the
Mortgaged Property, consider such risks and only take action in accordance with
its established environmental review procedures.

            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 Pooling and Servicing
Agreement and the Trustee's capacity thereunder. Pursuant to its efforts to sell
such REO Property, the Master Servicer shall either itself or through an agent
selected by the Master Servicer protect and conserve such REO Property in the
same manner and to such extent as is customary in the locality where such REO
Property is located and may, incident to its conservation and protection of the
interests of the Certificateholders, rent the same, or any part thereof, as the
Master Servicer deems to be in the best interest of the Certificateholders for
the period prior to the sale of such REO Property. The Master Servicer shall
prepare for and deliver to the Trustee a statement with respect to each REO
Property that has been rented 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. The net monthly rental
income, if any, from such REO Property shall be deposited in the Certificate
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 any tax
reporting 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, and delivering the
same to the Trustee for execution, if required, and by filing the same.

            In the event that the Trust Fund acquires any Mortgaged Property as
aforesaid or otherwise in connection with a default or imminent default on a
Mortgage Loan, the Master Servicer shall dispose of such Mortgaged Property
prior to three years after its acquisition by the Trust Fund unless the Trustee
shall have been supplied with an Opinion of Counsel to the effect that the
holding by the Trust Fund of such Mortgaged Property subsequent to such
three-year period will not result in the imposition of taxes on "prohibited
transactions" of any REMIC hereunder as defined in section 860F of the Code or
cause any REMIC hereunder to fail to qualify as a REMIC at any time that any
Certificates are outstanding, in which case the Trust Fund may continue to hold
such Mortgaged Property (subject to any conditions contained in such Opinion of
Counsel). Notwithstanding any other provision of this Agreement, no Mortgaged
Property acquired by the Trust Fund 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 Fund 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 hereunder 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
Fund with respect to the imposition of any such taxes.


                                       47
<PAGE>   53

            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 and if such determination cannot to be made, the Master
Servicer shall deal with such Mortgage Loan in a manner consistent with the
servicing standard in Section 3.01 hereof. 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, Advances and Servicing
Advances, shall be applied to the payment of principal of and interest on the
related defaulted Mortgage Loans (with interest 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 Certificate 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 Advances; third, to reimburse the Certificate Account for any
Nonrecoverable Advances (or portions thereof) that were previously withdrawn by
the Master Servicer pursuant to Section 3.08(a)(iii) that related to such
Mortgage Loan; fourth, to accrued and unpaid interest (to the extent no Advance
has been made for such amount or any such Advance has been reimbursed) on the
Mortgage Loan or related REO Property, at the Adjusted Net Mortgage Rate to the
Due Date occurring in the month in which such amounts are required to be
distributed; and fifth, as a recovery of principal of the Mortgage Loan. Excess
Proceeds, if any, from the liquidation of a Liquidated Mortgage Loan will be
retained by the Master Servicer as additional servicing compensation pursuant to
Section 3.14.

            The Master Servicer, in its sole discretion, shall have the right to
purchase for its own account from the Trust Fund any Mortgage Loan which is 91
days or more delinquent at a price equal to the Purchase Price. The Purchase
Price for any Mortgage Loan purchased hereunder shall be deposited in the
Certificate Account and the Trustee, upon receipt of a certificate from the
Master Servicer in the form of Exhibit N hereto, shall release or cause to be
released to the purchaser of such Mortgage Loan the related Mortgage File and
shall execute and deliver such instruments of transfer or assignment prepared by
the purchaser of such Mortgage Loan, in each case without recourse, as shall be
necessary to vest in the purchaser of such Mortgage Loan any Mortgage Loan
released pursuant hereto and the purchaser of such Mortgage Loan shall succeed
to all the Trustee's right, title and interest in and to such Mortgage Loan and
all security and documents related thereto. Such assignment shall be an
assignment outright and not for security. The purchaser of such Mortgage Loan
shall thereupon own such Mortgage Loan, and all security and documents, free of
any further obligation to the Trustee or the Certificateholders with respect
thereto.

            SECTION 3.12. 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 by delivering, or causing to be delivered a "Request for 


                                       48
<PAGE>   54

Release" substantially in the form of Exhibit N. Upon receipt of such request,
the Trustee shall promptly release the related Mortgage File to the Master
Servicer, and 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 shall, upon delivery
to the Trustee of a Request for Release in the form of Exhibit M signed by a
Servicing Officer, release the Mortgage File to the Master Servicer. Subject to
the further limitations set forth below, the Master Servicer shall cause the
Mortgage File or documents so released to be returned to the Trustee 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 Certificate Account,
in which case the Master Servicer shall deliver to the Trustee a Request for
Release in the form of Exhibit N, signed by a Servicing Officer.

            If the Master Servicer at any time seeks to initiate a foreclosure
proceeding in respect of any Mortgaged Property as authorized by this Agreement,
the Master Servicer shall 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.

            SECTION 3.13. Documents Records and Funds in Possession of Master
                          Servicer to be Held for the Trustee.

            Notwithstanding any other provisions of this Agreement, the Master
Servicer shall transmit to the Trustee 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. 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
Certificate 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 create, incur or subject any Mortgage
File or any funds that are deposited in the Certificate 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, 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.


                                       49
<PAGE>   55

            SECTION 3.14. Servicing Compensation.

            As compensation for its activities hereunder, the Master Servicer
shall be entitled to retain or withdraw from the Certificate Account an amount
equal to the Master Servicing Fee for each Mortgage Loan, provided that the
aggregate Master Servicing Fee with respect to any Distribution Date shall be
reduced (i) by an amount equal to the aggregate of the Prepayment Interest
Shortfalls, if any, with respect to such Distribution Date, but not below an
amount equal to the aggregate Master Servicing Fee for such Distribution Date
before reduction thereof in respect of such Prepayment Interest Shortfalls, and
(ii) with respect to the first Distribution Date, an amount equal to any amount
to be deposited into the Distribution Account by the Depositor pursuant to
Section 2.01(a) and not so deposited.

            Additional 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 shall be retained by
the Master Servicer to the extent not required to be deposited in the
Certificate Account pursuant to Section 3.05 hereof. The Master Servicer shall
be required to pay all expenses incurred by it in connection with its master
servicing activities hereunder (including payment of any premiums for hazard
insurance and any Primary Insurance Policy and maintenance of the other forms of
insurance coverage required by this Agreement) and shall not be entitled to
reimbursement therefor except as specifically provided in this Agreement.

            SECTION 3.15. Access to Certain Documentation.

            The Master Servicer shall provide to the OTS and the FDIC and to
comparable regulatory authorities supervising Holders of Subordinated
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 shall limit the obligation of the Master Servicer to
observe any applicable law prohibiting disclosure of information regarding the
Mortgagors and the failure of the Master Servicer to provide access as provided
in this Section as a result of such obligation shall not constitute a breach of
this Section.

            SECTION 3.16. Annual Statement as to Compliance.

            The Master Servicer shall deliver to the Depositor and the Trustee
on or before 120 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 (i) a review of the activities of the Master Servicer
during the preceding Fiscal Year and of the performance of the Master Servicer
under this Agreement has been made under such officer's supervision and (ii) 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. The Trustee shall forward a copy of each such statement to each Rating
Agency.

            SECTION 3.17. Annual Independent Public Accountants' Servicing
                          Statement; Financial Statements.

            On or before 120 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 nationally or regionally 


                                       50
<PAGE>   56

recognized 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 and the Depositor to the effect that such firm has
examined the Master Servicer's assertion of its compliance with the minimum
standards of the Uniform Single Attestation Program for Mortgage Bankers
("USAP"), to the extent applicable and that, on the basis of such examination,
conducted substantially in compliance with USAP to the extent applicable, such
assertion is fairly stated in all material respects except for such significant
exceptions or errors in records that, in the opinion of such firm, USAP requires
it to report. In rendering such statement, such firm may rely, as to matters
relating to direct servicing of mortgage loans by Subservicers, upon comparable
statements for examinations conducted substantially in compliance with the
Uniform Single Attestation Program for Mortgage Bankers or the Audit Program for
Mortgages serviced for FNMA and FHLMC (rendered within one year of such
statement) of independent public accountants with respect to the related
Subservicer. Copies of such statement shall be provided by the Trustee to any
Certificateholder upon request at the Master Servicer's expense, provided such
statement is delivered by the Master Servicer to the Trustee.

            SECTION 3.18. Errors and Omissions Insurance; Fidelity Bonds.

            The Master Servicer shall for so long as it acts as master servicer
under this Agreement, obtain and maintain in force (a) a policy or policies of
insurance covering errors and omissions in the performance of its obligations as
Master Servicer hereunder and (b) a fidelity bond in respect of its officers,
employees and agents. Each such policy or policies and bond shall, together,
comply with the requirements from time to time of FNMA or FHLMC for persons
performing servicing for mortgage loans purchased by FNMA or FHLMC. In the event
that any such policy or bond ceases to be in effect, the Master Servicer shall
obtain a comparable replacement policy or bond from an insurer or issuer,
meeting the requirements set forth above as of the date of such replacement.

                                   ARTICLE IV

                                DISTRIBUTIONS AND
                         ADVANCES BY THE MASTER SERVICER

            SECTION 4.01. Advances.

            The Master Servicer shall determine on or before each Master
Servicer Advance Date whether it is required to make an Advance pursuant to the
definition thereof. If the Master Servicer determines it is required to make an
Advance, it shall, on or before the Master Servicer Advance Date, either (i)
deposit into the Certificate Account an amount equal to the Advance or (ii) make
an appropriate entry in its records relating to the Certificate Account that any
Amount Held for Future Distribution has been used by the Master Servicer in
discharge of its obligation to make any such Advance. Any funds so applied shall
be replaced by the Master Servicer by deposit in the Certificate Account no
later than the close of business on the next Master Servicer Advance Date. The
Master Servicer shall be entitled to be reimbursed from the Certificate Account
for all Advances of its own funds made pursuant to this Section as provided in
Section 3.08. The obligation to make Advances with respect to any Mortgage Loan
shall continue if such Mortgage Loan has been foreclosed or otherwise terminated
and the related Mortgaged Property has not been liquidated.


                                       51
<PAGE>   57

            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 Advance determined by the Master Servicer
to be a Nonrecoverable Advance.

            SECTION 4.02. Priorities of Distribution.

                  (a) (1) With respect to the Available Funds for the Loan Group
            One and Remaining Available Funds for Loan Group Two, on each
            Distribution Date, the Trustee shall, to the extent on deposit
            therein, withdraw such Available Funds from the Distribution Account
            and apply such funds to distributions on the specified Classes of
            Senior Certificates in Certificate Group One, in the following order
            and priority and, in each case, to the extent of such funds
            remaining:

                        (i) concurrently, to each interest-bearing Class of
                  Senior Certificates and the Class X-1 Component an amount
                  allocable to interest equal to the related Class Optimal
                  Interest Distribution Amount, any shortfall being allocated
                  among such Classes and Component in proportion to the amount
                  of the Class Optimal Interest Distribution Amount that would
                  have been distributed in the absence of such shortfall;

                        (ii) [Reserved for distribution of Accrual Amount, if
                  any.]

                        (iii) to each Class of Senior Certificates as follows:

                             (x) [reserved];

                             (y) on each Distribution Date prior to the Senior
                        Credit Support Depletion Date, up to the amount of the
                        related Senior Principal Distribution Amount for such
                        Distribution Date will be distributed as principal to
                        the following Classes of Senior Certificates, in the
                        following order of priority:

            (A)   to the Class A-R Certificates, until the Class Certificate
                  Balance thereof is reduced to zero;

            (B)   to the Class A-4 Certificates, the Priority Amount until the
                  Class Certificate Balance thereof is reduced to zero; and

            (C)   sequentially, to the Class A-1, Class A-2, Class A-3 and Class
                  A-4 Certificates, in that order, until the respective Class
                  Certificate Balances thereof are reduced to zero.

                  (2) With respect to the Available Funds for Loan Group Two on
            each Distribution Date and Remaining Available Funds for Loan Group
            One, the Trustee shall, to the extent on deposit therein, withdraw
            such Available Funds from the Distribution Account and apply such
            funds on the Senior Certificates in Certificate Group Two, in the
            following order and priority and, in each case, to the extent of
            such funds remaining:

                        (i) concurrently, to each interest-bearing Class of
                  Senior Certificates and the Class X-2 Component an amount
                  allocable to interest equal to the related Class Optimal
                  Interest Distribution Amount, any shortfall being allocated
                  among such Classes and Component in proportion to the amount
                  of the Class Optimal Interest Distribution Amount that would
                  have been distributed in the absence of such shortfall;

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

                              (x) [reserved]

                              (y) to the Class A-5 Certificates an amount
                        allocable to principal, up to the amount of the related
                        Senior Principal Distribution Amount for such
                        Distribution Date, until the Class Certificate Balance
                        thereof is reduced to zero.

                  (3) On each Distribution Date, Available Funds from both Loan
            Groups remaining after making the distributions described in 4.02
            (a) (1) and 4.02 (a) (2) above, will be distributed to the
            Subordinated Certificates in the following order and priority and,
            in each case, to the extent of such funds remaining:

                  (A) to the Class B-1 Certificates, an amount allocable to
            interest equal to the Class Optimal Interest Distribution Amount for
            such Distribution Date;

                  (B) to the Class B-1 Certificates, an amount allocable to

                  (E) to the Class B-3 Certificates, an amount allocable to
            interest equal to the Class Optimal Interest Distribution Amount for
            such Class for such Distribution Date;

                  (F) to the Class B-3 Certificates, an amount allocable to
            principal equal to its Pro Rata Share for such Distribution Date
            until the Class Certificate Balance thereof is reduced to zero;

                  (G) to the Class B-4 Certificates, an amount allocable to

            Distribution Amount for such Class for such Distribution Date;

                  (H) to the Class B-4 Certificates, an amount allocable to
            principal equal to its Pro Rata Share for such Distribution Date
            until the Class Certificate Balance thereof has been reduced to
            zero;


                                       53
<PAGE>   59

                  (I) to the Class B-5 Certificates, an amount allocable to
            interest equal to the amount of the Class Optimal Interest
            Distribution Amount for such Class for such Distribution Date;

                  (J) to the Class B-5 Certificates, an amount allocable to
            principal equal to its Pro Rata Share for such Distribution Date
            until the Class Certificate Balance thereof has been reduced to
            zero;

                  (K) to the Class B-6 Certificates, an amount allocable to
            interest equal to the Class Optimal Interest Distribution Amount for
            such Class for such Distribution Date; and

                  (L) to the Class B-6 Certificates, an amount allocable to
            principal equal to its Pro Rata Share for such Distribution Date
            until the Class Certificate Balance thereof is reduced to zero.

            (iii) to the Class A-R Certificates, any remaining funds.


            (b) [Reserved for allocation of Accrual Amount, if any.]

            (c) On each Distribution Date on or after the Senior Credit Support
Depletion Date, notwithstanding the allocation and priority set forth in Section
4.02(a)(1)(iii)(y), the portion of Available Funds for Loan Group One and
Remaining Available Funds for Loan Group Two available to be distributed as
principal of the related Senior Certificates shall be distributed concurrently,
as principal, on such Classes, pro rata, on the basis of their respective Class
Certificate Balances, until the Class Certificate Balances thereof are reduced
to zero.

            (d) On each Distribution Date, the amount referred to in clause (i)
of the definition of Class Optimal Interest Distribution Amount for each Class
of Senior Certificates and Component in a Certificate Group and each Class of
Subordinated Certificates for such Distribution Date shall be reduced with
respect to each Loan Group by (i) the related Class' or Component's pro rata
share of Net Prepayment Interest Shortfalls for such Loan Group based (x) with
respect to a Class of Senior Certificates and Component, the related Class
Optimal Interest Distribution Amount and, (y) with respect to a Class of
Subordinated Certificates on and prior to a Senior Termination Date for the
related Certificate Group, the Assumed Interest Amount or after such Senior
Termination Date, the related Class Optimal Interest Distribution Amount without
taking into account such Net Prepayment Interest Shortfalls, (ii) after the
Special Hazard Coverage Termination Date, with respect to each Mortgage Loan in
the related Loan Group that became a Special Hazard Mortgage Loan during the
calendar month preceding the month of such Distribution Date, the excess of one
month's interest at the related Adjusted Net Mortgage Rate on the Stated
Principal Balance of such Mortgage Loan as of the Due Date in such month over
the amount of Liquidation Proceeds applied as interest on such Mortgage Loan
with respect to such month, (iii) after the Bankruptcy Coverage Termination
Date, with respect to each Mortgage Loan in the related Loan Group that became
subject to a Bankruptcy Loss during the calendar month preceding the month of
such Distribution Date, the interest portion of the related Debt Service
Reduction or Deficient Valuation, (iv) each Relief Act Reduction incurred during
the calendar month preceding the month of such Distribution Date and (v) after
the Fraud Coverage Termination Date, with respect to each Mortgage Loan in the
related Loan Group that became a Fraud Loan during the calendar month preceding
the month of such Distribution Date, the excess of one month's interest at the
related Adjusted 


                                       54
<PAGE>   60

Net Mortgage Rate on the Stated Principal Balance of such Mortgage Loan as of
the Due Date in such month over the amount of Liquidation Proceeds applied as
interest on such Mortgage Loan with respect to such month.

            (e) Notwithstanding the priority and allocation contained in Section
4.02(a)(3), if with respect to any Class of Subordinated Certificates on any
Distribution Date the sum of the related Class Subordination Percentages of such
Class and of all Classes of Subordinated Certificates which have a higher
numerical Class designation than such Class (the "Applicable Credit Support
Percentage") is less than the Original Applicable Credit Support Percentage for
such Class, no distribution of Principal Prepayments will be made to any such
Classes (the "Restricted Classes") and the amount of such Principal Prepayments
otherwise distributable to the Restricted Classes shall be distributed to any
Classes of Subordinated Certificates having lower numerical Class designations
than such Class, pro rata, based on their respective Class Certificate Balances
immediately prior to such Distribution Date and shall be distributed in the
sequential order provided in Section 4.02(a)(3).

            SECTION 4.03. Allocation of Realized Losses.

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

            (i) any Realized Loss (other than an Excess Loss) shall be allocated
      first to the Subordinated Certificates in reverse order of their
      respective numerical Class designations (beginning with the Class of
      Subordinated 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 in
      the Certificate Group related to the Loan Group that experienced such
      Realized Loss (other than the Notional Amount 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;

            (ii) any Excess Losses on the Mortgage Loans in a Loan Group shall
      be allocated to the related Senior Certificates (other than the Notional
      Amount Certificates) and the Subordinated Certificates then outstanding,
      pro rata, on the basis of, with respect to such Senior Certificates, their
      respective Class Certificate Balances and, with respect to each Class of
      Subordinated Certificates, the applicable Assumed Balance for each such
      Class relating to the Loan Group in which such Realized Loss occurs;
      provided, however, on any Distribution Date after a Senior Termination
      Date for a Certificate Group, such Excess Losses on the Mortgage Loans in
      the related Loan Group will be allocated to the Subordinated Certificates
      on the basis of their respective Class Certificate Balances and to the
      remaining Senior Certificates.

            (b) The Class Certificate Balance of the Class of Subordinated
      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 on such Distribution Date) exceeds the
      Pool Stated Principal Balance for the following Distribution Date.


                                       55
<PAGE>   61

            (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 4.03(a) above shall be allocated among the Certificates of such Class
in proportion to their respective Certificate Balances.

            (d) Any allocation of Realized Losses to a Certificate or to any
Component or any reduction in the Certificate Balance of a Certificate, pursuant
to Section 4.03(a) above shall be accomplished by reducing the Certificate
Balance or Component Balance thereof, as applicable, immediately following the
distributions made on the related Distribution Date in accordance with the
definition of "Certificate Balance" or "Component Balance," as the case may be.

            SECTION 4.04. Monthly Statements to Certificateholders.

            (a) Not later than each Distribution Date, the Trustee shall prepare
and cause to be forwarded by first class mail to each Certificateholder, the
Master Servicer and the Depositor a statement setting forth with respect to the
related distribution:

                  (i) the amount thereof allocable to principal for each
            Certificate Group, separately identifying the aggregate amount of
            any Principal Prepayments and Liquidation Proceeds included therein;

                  (ii) the amount thereof allocable to interest for each
            Certificate Group, any Class Unpaid Interest Shortfall included in
            such distribution and any remaining Class Unpaid Interest Shortfall
            after giving effect to such distribution;

                  (iii) if the distribution to the Holders of such Class of
            Certificates is less than the full amount that would be
            distributable to such Holders if there were sufficient funds
            available therefor, the amount of the shortfall and the allocation
            thereof as between principal and interest;

                  (iv) the Class Certificate Balance of each Class of
            Certificates after giving effect to the distribution of principal on
            such Distribution Date;

                  (v) the Pool Stated Principal Balance and each Loan Group
            Balance for the following Distribution Date;

            retained by the Master Servicer with respect to such Distribution
            Date;

                  (viii) the Pass-Through Rate for each such Class of
            Certificates with respect to such Distribution Date;

                  (ix) the amount of Advances included in the distribution on
            such Distribution Date and the aggregate amount of Advances
            outstanding as of the close of business on such Distribution Date;


                                       56
<PAGE>   62

                  (x) the number and aggregate principal amounts of Mortgage
            Loans by Loan Group (A) delinquent (exclusive of Mortgage Loans in
            foreclosure) (1) 1 to 30 days (2) 31 to 60 days (3) 61 to 90 days
            and (4) 91 or more days and (B) in foreclosure and delinquent (1) 1
            to 30 days (2) 31 to 60 days (3) 61 to 90 days and (4) 91 or more
            days, as of the close of business on the last day of the calendar
            month preceding such Distribution Date;

                  (xi) with respect to any Mortgage Loan that became an REO
            Property during the preceding calendar month, the loan number and
            Stated Principal Balance of such Mortgage Loan as of the close of
            business on the last day of the calendar month preceding such
            Distribution Date;

                  (xii) the total number and principal balance of any REO
            Properties by Loan Group (and market value, if available) as of the
            close of business on the last day of the calendar month preceding
            such Distribution Date;

                  (xiii) each Senior Prepayment Percentage for the following
            Distribution Date;

                  (xiv) the aggregate amount of Realized Losses by Loan Group
            incurred during the preceding calendar month; and

                  (xv) the Special Hazard Loss Coverage Amount, the Fraud Loss
            Coverage Amount and the Bankruptcy Loss Coverage Amount, in each
            case as of the related Determination Date.

            (b) The Trustee's responsibility for disbursing the above
information to the Certificateholders is limited to the availability, timeliness
and accuracy of the information provided by the Master Servicer. The Trustee
will send a copy of each statement provided pursuant to this Section 4.04 to
each Rating Agency.

            (c) Within one Business Day of each Determination Date, the Master
Servicer shall deliver to the Trustee (which delivery may be by electronic data
transmission) a report in substantially the form set forth as Schedule V hereto.

            (d) Within a reasonable period of time after the end of each
calendar year, the Trustee shall cause to be furnished to each Person who at any
time during the calendar year was a Certificateholder, a statement containing
the information set forth in clauses (a)(i), (a)(ii) and (a)(vii) of this
Section 4.04 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 effect.

            SECTION 4.05. Determination of Pass-Through Rates for COFI
                          Certificates.

            The Pass-Through Rate for each Class of COFI Certificates for each
Interest Accrual Period after the initial Interest Accrual Period shall be
determined by the Trustee as provided below on the basis of the Index and the
applicable formulae appearing in footnotes corresponding to the COFI
Certificates in the table relating to the Certificates in the Preliminary
Statement.


                                       57
<PAGE>   63

            Except as provided below, with respect to each Interest Accrual
Period following the initial Interest Accrual Period, the Trustee shall not
later than two Business Days following the publication of the applicable Index
determine the Pass-Through Rate at which interest shall accrue in respect of the
COFI Certificates during the related Interest Accrual Period.

            Except as provided below, the Index to be used in determining the
respective Pass-Through Rates for the COFI Certificates for a particular
Interest Accrual Period shall be COFI for the second calendar month preceding
such Interest Accrual Period. If at the Outside Reference Date for any Interest
Accrual Period, COFI for the second calendar month preceding such Interest
Accrual Period has not been published, the Trustee shall use COFI for the third
calendar month preceding such Interest Accrual Period. If COFI for neither the
second nor third calendar months preceding any Interest Accrual Period has been
published on or before the related Outside Reference Date, the Index for such
Interest Accrual Period and for all subsequent Interest Accrual Periods shall be
the National Cost of Funds Index for the third calendar month preceding such
Interest Accrual Period (or the fourth preceding calendar month if such National
Cost of Funds Index for the third preceding calendar month has not been
published by such Outside Reference Date). In the event that the National Cost
of Funds Index for neither the third nor fourth calendar months preceding an
Interest Accrual Period has been published on or before the related Outside
Reference Date, then for such Interest Accrual Period and for each succeeding
Interest Accrual Period, the Index shall be LIBOR, determined in the manner set
forth below.

            On each Interest Determination Date so long as the COFI Certificates
are outstanding and the applicable Index therefor is LIBOR, the Trustee shall
either (i) request each Reference Bank to inform the Trustee of the quotation
offered by its principal London office for making one-month United States dollar
deposits in leading banks in the London interbank market, as of 11:00 a.m.
(London time) on such Interest Determination Date or (ii) in lieu of making any
such request, rely on such Reference Bank quotations that appear at such time on
the Reuters Screen LIBO Page (as defined in the International Swap Dealers
Association Inc. Code of Standard Wording, Assumptions and Provisions for Swaps,
1986 Edition), to the extent available.

            With respect to any Interest Accrual Period for which the applicable
Index is LIBOR, LIBOR for such Interest Accrual Period will be established by
the Trustee on the related Interest Determination Date as follows:

            (a) If on any Interest Determination Date two or more Reference
      Banks provide such offered quotations, LIBOR for the next Interest Accrual
      Period shall be the arithmetic mean of such offered quotations (rounding
      such arithmetic mean upwards if necessary to the nearest whole multiple of
      1/32%).

            (b) If on any Interest Determination Date only one or none of the
      Reference Banks provides such offered quotations, LIBOR for the next
      Interest Accrual Period shall be whichever is the higher of (i) LIBOR as
      determined on the previous Interest Determination Date or (ii) the Reserve
      Interest Rate. The "Reserve Interest Rate" shall be the rate per annum
      which the Trustee determines to be either (i) the arithmetic mean (rounded
      upwards if necessary to the nearest whole multiple of 1/32%) of the
      one-month United States dollar lending rates that New York City banks
      selected by the Trustee are quoting, on the relevant Interest
      Determination Date, to the principal London offices of at least two of the
      Reference Banks to which such quotations are, in the opinion of the
      Trustee, being so made, or (ii) in the event that the Trustee can
      determine no such arithmetic mean, the lowest one-month United States
      dollar lending rate which New York 


                                       58
<PAGE>   64

      City banks selected by the Trustee are quoting on such Interest
      Determination Date to leading European banks.

            From such time as the applicable Index becomes LIBOR until all of
the COFI Certificates are paid in full, the Trustee will at all times retain at
least four Reference Banks for the purposes of determining LIBOR with respect to
each interest Determination Date. The Master Servicer initially shall designate
the Reference Banks. Each "Reference Bank" shall be a leading bank engaged in
transactions in Eurodollar deposits in the international Eurocurrency market,
shall not control, be controlled by, or be under common control with, the
Trustee and shall have an established place of business in London. If any such
Reference Bank should be unwilling or unable to act as such or if the Master
Servicer should terminate its appointment as Reference Bank, the Trustee shall
promptly appoint or cause to be appointed another Reference Bank. The Trustee
shall have no liability or responsibility to any Person for (i) the selection of
any Reference Bank for purposes of determining LIBOR or (ii) any inability to
retain at least four Reference Banks which is caused by circumstances beyond its
reasonable control.

            In determining LIBOR and any Pass-Through Rate for the COFI
Certificates or any Reserve Interest Rate, the Trustee may conclusively rely and
shall be protected in relying upon the offered quotations (whether written, oral
or on the Reuters Screen) from the Reference Banks or the New York City banks as
to LIBOR or the Reserve Interest Rate, as appropriate, in effect from time to
time. The Trustee shall not have any liability or responsibility to any Person
for (i) the Trustee's selection of New York City banks for purposes of
determining any Reserve Interest Rate or (ii) its inability, following a
good-faith reasonable effort, to obtain such quotations from the Reference Banks
or the New York City banks or to determine such arithmetic mean, all as provided
for in this Section 4.06.

            The establishment of LIBOR and each Pass-Through Rate for the LIBOR
Certificates by the Trustee shall (in the absence of manifest error) be final,
conclusive and binding upon each Holder of a Certificate and the Trustee.

            SECTION 4.06. Determination of Pass-Through Rates for LIBOR
                          Certificates.

            On each Interest Determination Date so long as the LIBOR
Certificates are outstanding, the Trustee shall either (i) request each
Reference Bank to inform the Trustee of the quotation offered by its principal
London office for making one-month United States dollar deposits in leading
banks in the London interbank market, as of 11:00 a.m. (London time) on such
Interest Determination Date or (ii) in lieu of making any such request, rely on
such Reference Bank quotations that appear at such time on the Reuters Screen
LIBO Page (as defined in the International Swap Dealers Association Inc. Code of
Standard Wording, Assumptions and provisions for Swaps, 1986 Edition), to the
extent available.

            LIBOR for the next Interest Accrual Period will be established by
the Trustee on each interest Determination Date as follows:

            (a) If on any interest Determination Date two or more Reference
      Banks provide such offered quotations, LIBOR for the next Interest Accrual
      Period shall be the arithmetic mean of such offered quotations (rounding
      such arithmetic mean upwards if necessary to the nearest whole multiple of
      1/32%).

            (b) If on any Interest Determination Date only one or none of the
      Reference Banks provides such offered quotations, LIBOR for the next
      Interest Accrual Period shall be whichever 


                                       59
<PAGE>   65

      is the higher of (i) LIBOR as determined on the previous Interest
      Determination Date or (ii) the Reserve Interest Rate. The "Reserve
      Interest Rate" shall be the rate per annum which the Trustee determines to
      be either (i) the arithmetic mean (rounded upwards if necessary to the
      nearest whole multiple of 1/32%) of the one-month United States dollar
      lending rates that New York City banks selected by the Trustee are
      quoting, on the relevant Interest Determination Date, to the principal
      London offices of at least two of the Reference Banks to which such
      quotations are, in the opinion of the Trustee, being so made, or (ii) in
      the event that the Trustee can determine no such arithmetic mean, the
      lowest one-month United States dollar lending rate which New York City
      banks selected by the Trustee are quoting on such Interest Determination
      Date to leading European banks.

            (c) If on any interest Determination Date the trustee is required
      but is unable to determine the Reserve Interest Rate in the manner
      provided in paragraph (b) above, LIBOR shall be LIBOR as determined on the
      preceding Interest Determination Date, or, in the case of the first
      Interest Determination Date, the Initial LIBOR Rate.

            Until all of the LIBOR Certificates are paid in full, the Trustee
will at all times retain at least four Reference Banks for the purpose of
determining LIBOR with respect to each Interest Determination Date. The Master
Servicer initially shall designate the Reference Banks. Each "Reference Bank"
shall be a leading bank engaged in transactions in Eurodollar deposits in the
international Eurocurrency market, shall not control, be controlled by, or be
under common control with, the Trustee and shall have an established place of
business in London. If any such Reference Bank should be unwilling or unable to
act as such or if the Master Servicer should terminate its appointment as
Reference Bank, the Trustee shall promptly appoint or cause to be appointed
another Reference Bank. The Trustee shall have no liability or responsibility to
any Person for (i) the selection of any Reference Bank for purposes of
determining LIBOR or (ii) any inability to retain at least four Reference Banks
which is caused by circumstances beyond its reasonable control.

            The Pass-Through Rate for each Class of LIBOR Certificates for each
Interest Accrual Period shall be determined by the Trustee on each Interest
Determination Date so long as the LIBOR Certificates are outstanding on the
basis of LIBOR and the respective formulae appearing in footnotes corresponding
to the LIBOR Certificates in the table relating to the Certificates in the
Preliminary Statement.

            In determining LIBOR, any Pass-Through Rate for the LIBOR
Certificates or any Reserve Interest Rate, the Trustee may conclusively rely and
shall be protected in relying upon the offered quotations (whether written, oral
or on the Reuters Screen) from the Reference Banks or the New York City banks as
to LIBOR or the Reserve Interest Rate, as appropriate, in effect from time to
time. The Trustee shall not have any liability or responsibility to any Person
for (i) the Trustee's selection of New York City banks for purposes of
determining any Reserve Interest Rate or (ii) its inability, following a
good-faith reasonable effort, to obtain such quotations from the Reference Banks
or the New York City banks or to determine such arithmetic mean, all as provided
for in this Section 4.07.

            The establishment of LIBOR and each Pass-Through Rate for the LIBOR
Certificates by the Trustee shall (in the absence of manifest error) be final,
conclusive and binding upon each Holder of a Certificate and the Trustee.

                                THE CERTIFICATES

            SECTION 5.01. The Certificates.

            The Certificates shall be substantially in the forms attached hereto
as exhibits. The Certificates shall be issuable in registered form, in the
minimum denominations, integral multiples in excess thereof (except that one
Certificate in each Class may be issued in a different amount which must be in
excess of the applicable minimum denomination) and aggregate denominations per
Class set forth in the Preliminary Statement.

            Subject to Section 9.02 hereof respecting the final distribution on
the Certificates, on each Distribution Date the Trustee shall make distributions
to each Certificateholder of record on the preceding Record Date either (x) by
wire transfer in immediately available funds to the account of such holder at a
bank or other entity having appropriate facilities therefor, if (i) such Holder
has so notified the Trustee at least five Business Days prior to the related
Record Date and (ii) such Holder shall hold (A) a Notional Amount Certificate,
(B) 100% of the Class Certificate Balance of any Class of Certificates or (C)
Certificates of any Class with aggregate principal Denominations of not less
than $1,000,000 or (y) by check mailed by first class mail to such
Certificateholder at the address of such holder appearing in the Certificate
Register.

            The Certificates shall be executed by manual or facsimile signature
on behalf of the Trustee by an authorized officer. 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 at the date of such Certificate. No Certificate shall be
entitled to any benefit under this Agreement, or be valid for any purpose,
unless countersigned by the Trustee by manual signature, and such
countersignature upon any Certificate shall be conclusive evidence, and the only
evidence, that such Certificate has been duly executed and delivered hereunder.
All Certificates shall be dated the date of their countersignature. On the
Closing Date, the Trustee shall countersign the Certificates to be issued at the
direction of the Depositor, or any affiliate thereof.

            The Depositor shall provide, or cause to be provided, to the Trustee
on a continuous basis, an adequate inventory of Certificates to facilitate
transfers.

            SECTION 5.02. Certificate Register; Registration of Transfer and
                          Exchange of Certificates.

            (a) The Trustee shall maintain, or cause to be maintained in
accordance with the provisions of Section 5.06 hereof, a Certificate Register
for the Trust Fund in which, subject to the provisions of subsections (b) and
(c) below and 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. Upon surrender for registration of
transfer of any Certificate, the Trustee shall execute and deliver, in the name
of the designated transferee or transferees, one or more new Certificates of the
same Class and aggregate Percentage Interest.


                                       61
<PAGE>   67

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

            No service charge to the Certificateholders shall be made for any
registration of transfer or exchange of Certificates, but 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 may be required.

            All Certificates surrendered for registration of transfer or
exchange shall be cancelled and subsequently destroyed by the Trustee in
accordance with the Trustee's customary procedures.

            (b) No transfer of a Private Certificate shall be made unless such
transfer is made pursuant to an effective registration statement under the
Securities Act and any applicable state securities laws or is exempt from the
registration requirements under said Act and such state securities laws. In the
event that a transfer is to be made in reliance upon an exemption from the
Securities Act and such laws, in order to assure compliance with the Securities
Act and such laws, the Certificateholder desiring to effect such transfer and
such Certificateholder's prospective transferee shall each certify to the
Trustee in writing the facts surrounding the transfer in substantially the forms
set forth in Exhibit J-1 or J-2 as applicable (the "Transferor Certificate") and
(i) deliver a letter in substantially the form of either Exhibit K (the
"Investment Letter") or Exhibit L (the "Rule 144A Letter") or (ii) there shall
be delivered to the Trustee at the expense of the transferor an Opinion of
Counsel that such transfer may be made pursuant to an exemption from the
Securities Act. The Depositor shall provide to any Holder of a Private
Certificate and any prospective transferee 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 Securities Act pursuant to the registration
exemption provided by Rule 144A. The Trustee and the Master Servicer shall
cooperate with the Depositor in providing the Rule 144A information referenced
in the preceding sentence, including providing to the Depositor such information
regarding the Certificates, the Mortgage Loans and other matters regarding the
Trust Fund as the Depositor shall reasonably request to meet its obligation
under the preceding sentence. Each Holder of a Private Certificate desiring to
effect such transfer shall, and does hereby agree to, indemnify the Trustee and
the Depositor, the Seller and the Master Servicer against any liability that may
result if the transfer is not so exempt or is not made in accordance with such
federal and state laws.

            No transfer of an ERISA-Restricted Certificate shall be made unless
the Trustee shall have received either (i) a representation from the transferee
of such Certificate acceptable to and in form and substance satisfactory to the
Trustee (in the event such Certificate is a Private Certificate, such
requirement is satisfied only by the Trustee's receipt of a representation
letter from the transferee substantially in the form of Exhibit K or Exhibit L),
to the effect that such transferee is not an employee benefit plan or
arrangement subject to Section 406 of ERISA or a plan or arrangement subject to
Section 4975 of the Code, nor a person acting on behalf of any such plan or
arrangement, nor using the assets of any such plan or arrangement to effect such
transfer, (ii) if the purchaser is an insurance company, a representation that
the purchaser is an insurance company which is purchasing such Certificates with


                                       62
<PAGE>   68

funds contained in an "insurance company general account" (as such term is
defined in Section V(e) of Prohibited Transaction Class Exemption 95-60 ("PTCE
95-60")) and that the purchase and holding of such Certificates are covered
under PTCE 95-60 or (iii) in the case of any such ERISA-Restricted Certificate
presented for registration in the name of an employee benefit plan subject to
ERISA, or a plan or arrangement subject to Section 4975 of the Code (or
comparable provisions of any subsequent enactments), or a trustee of any such
plan or any other person acting on behalf of any such plan or arrangement, or
using such plan's or arrangement's assets, an Opinion of Counsel satisfactory to
the Trustee, which Opinion of Counsel shall not be an expense of either the
Trustee or the Trust Fund, addressed to the Trustee 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 to any obligation in addition to those expressly undertaken in this
Agreement or to any liability. For purposes of the preceding sentence, with
respect to an ERISA-Restricted Certificate that is a Book-Entry Certificate, in
the event the representation letter referred to in the preceding sentence is not
so furnished, such representation shall be deemed to have been made to the
Trustee by the transferee's (including an initial acquiror's) acceptance of the
ERISA-Restricted Certificates. 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 without the
delivery to the Trustee of an Opinion of Counsel satisfactory to the Trustee as
described above shall be void and of no effect.

            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 5.02(b) 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.

            (c) 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
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 Ownership Interest in a Residual Certificate may be
      registered on the Closing Date or thereafter transferred, and the Trustee
      shall not register the Transfer of any Residual Certificate unless, in
      addition to the certificates required to be delivered to the Trustee under
      subparagraph (b) above, the Trustee shall have been furnished with an
      affidavit (a "Transfer Affidavit") (in the event such Residual Certificate
      is a Private Certificate) of the initial owner or the proposed transferee
      in the form attached hereto as Exhibit I.

            (iii) Each Person holding or acquiring any Ownership Interest in a
      Residual Certificate shall agree (A) to obtain a Transfer Affidavit from
      any other Person to whom such Person attempts to Transfer its Ownership
      Interest in a Residual Certificate, (B) to obtain a Transfer Affidavit
      from any Person for whom such Person is acting as nominee, trustee or
      agent in connection with any Transfer of a Residual Certificate and (C)
      not to Transfer its Ownership Interest in a Residual Certificate or to
      cause the Transfer of an Ownership Interest in a Residual 


                                       63
<PAGE>   69

      Certificate to any other Person if it has actual knowledge that such
      Person is not a Permitted Transferee.

            (iv) Any attempted or purported Transfer of any Ownership Interest
      in a Residual Certificate in violation of the provisions of this Section
      5.02(c) shall be absolutely null and void and shall vest no rights in the
      purported Transferee. If any purported transferee shall become a Holder of
      a Residual Certificate in violation of the provisions of this Section
      5.02(c), then the last preceding Permitted Transferee shall 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 Section 5.02(b) (in the event
      such Residual Certificate is a Private Certificate) and this Section
      5.02(c) 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 after
      receipt of the related Transfer Affidavit, Transferor Certificate and
      either the Rule 144A Letter or the Investment Letter (in the event such
      Residual Certificate is a Private Certificate). The Trustee shall be
      entitled but not obligated to recover from any Holder of a Residual
      Certificate that was in fact not a Permitted Transferee at the time it
      became a Holder or, at such subsequent time as it became other than a
      Permitted Transferee, all payments made on such Residual Certificate at
      and after either such time. Any such payments so recovered by the Trustee
      shall be paid and delivered by the Trustee to the last preceding Permitted
      Transferee of such Certificate.

            (v) The Depositor shall use its best efforts to make available, upon
      receipt of written request from the Trustee, all information necessary to
      compute any tax imposed under Section 860E(e) of the Code as a result of a
      Transfer of an Ownership Interest in a Residual Certificate to any Holder
      who is not a Permitted Transferee.

            The restrictions on Transfers of a Residual Certificate set forth in
this Section 5.02(c) shall cease to apply (and the applicable portions of the
legend on a Residual Certificate may be deleted) with respect to Transfers
occurring after delivery to the Trustee of an Opinion of Counsel, which Opinion
of Counsel shall not be an expense of the Trust Fund, the Trustee, the Seller or
the Master Servicer, to the effect that the elimination of such restrictions
will not cause any REMIC hereunder to fail to qualify as a REMIC at any time
that the Certificates are outstanding or result in the imposition of any tax on
the Trust Fund, a Certificateholder or another Person. Each Person holding or
acquiring any Ownership Interest in a Residual Certificate hereby consents to
any amendment of this Agreement which, based on an Opinion of Counsel furnished
to the Trustee, is reasonably necessary (a) to ensure that the record ownership
of, or any beneficial interest in, a Residual Certificate is not transferred,
directly or indirectly, to a Person that is not a Permitted Transferee and (b)
to provide for a means to compel the Transfer of a Residual Certificate which is
held by a Person that is not a Permitted Transferee to a Holder that is a
Permitted Transferee.

            (d) The preparation and delivery of all certificates and opinions
referred to above in this Section 5.02 in connection with transfer shall be at
the expense of the parties to such transfers.

            (e) Except as provided below, the Book-Entry Certificates shall at
all times remain registered in the name of the Depository or its nominee and at
all times: (i) registration of the Certificates may not be transferred by the
Trustee except to another Depository; (ii) 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; (iii) ownership and
transfers of registration of the Book-Entry 


                                       64
<PAGE>   70

Certificates on the books of the Depository shall be governed by applicable
rules established by the Depository; (iv) the Depository may collect its usual
and customary fees, charges and expenses from its Depository Participants; (v)
the Trustee shall deal with the Depository, Depository Participants and indirect
participating firms as representatives 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 such
representatives shall not be deemed to be inconsistent if they are made with
respect to different Certificate Owners; and (vi) 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.

            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.

            If (x) (i) the Depository or the Depositor advises the Trustee in
writing that the Depository is no longer willing or able to properly discharge
its responsibilities as Depository, and (ii) the Depositor is unable to locate a
qualified successor, (y) the Depositor at its option advises the Trustee in
writing that it elects to terminate the book-entry system through the Depository
or (z) after the occurrence of an Event of Default, Certificate Owners
representing at least 51% of the Certificate Balance 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 Depositor nor the Trustee shall
be liable for any delay in delivery of such instruction and each 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 issuance of Definitive Certificates the Trustee shall recognize the
Holders of the Definitive Certificates as Certificateholders hereunder.

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

            If (a) any mutilated Certificate is surrendered to the Trustee, or
the Trustee receives evidence to its satisfaction of the destruction, loss or
theft of any Certificate and (b) there is delivered to the Master Servicer and
the Trustee such security or indemnity as may be required by them to save each
of them harmless, then, in the absence of notice to the Trustee that such
Certificate has been acquired by a bona fide purchaser, the Trustee shall
execute, countersign and deliver, in exchange for or in lieu of any such
mutilated, destroyed, lost or stolen Certificate, a new Certificate of like
Class, tenor and Percentage Interest. In connection with the issuance of any new
Certificate under this Section 5.03, the Trustee may require the payment of a
sum sufficient to cover any tax or other governmental charge that may be imposed
in relation thereto and any other expenses (including the fees and expenses of
the Trustee) connected therewith. Any replacement Certificate issued pursuant to
this Section 5.03 shall constitute 


                                       65
<PAGE>   71

complete and indefeasible evidence of ownership, as if originally issued,
whether or not the lost, stolen or destroyed Certificate shall be found at any
time.

            SECTION 5.04. Persons Deemed Owners.

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

            SECTION 5.05. Access to List of Certificateholders' Names and
                          Addresses.

            If three or more Certificateholders (a) request such information in
writing from the Trustee, (b) state that such Certificateholders desire to
communicate with other Certificateholders with respect to their rights under
this Agreement or under the Certificates, and (c) provide a copy of the
communication which such Certificateholders propose to transmit, or if the
Depositor or Master Servicer shall request such information in writing from the
Trustee, then the Trustee shall, within ten Business Days after the receipt of
such request, provide the Depositor, the Master Servicer or such
Certificateholders at such recipients' expense the most recent list of the
Certificateholders of such Trust Fund held by the Trustee, if any. The Depositor
and every Certificateholder, by receiving and holding a Certificate, agree that
the Trustee shall not be held accountable by reason of the disclosure of any
such information as to the list of the Certificateholders hereunder, regardless
of the source from which such information was derived.

            SECTION 5.06. Maintenance of Office or Agency.

            The Trustee will maintain or cause to be maintained at its expense
an office or offices or agency or agencies in New York City where Certificates
may be surrendered for registration of transfer or exchange. The Trustee
initially designates its affiliate, Bankers Trust Company, Four Albany Street,
New York, New York 10006 for such purposes. The Trustee will give prompt written
notice to the Certificateholders of any change in such location of any such
office or agency.

                                   ARTICLE VI

                      THE DEPOSITOR AND THE MASTER SERVICER

            SECTION 6.01. Respective Liabilities of the Depositor and the Master
Servicer.

            The Depositor and the Master Servicer shall each be liable in
accordance herewith only to the extent of the obligations specifically and
respectively imposed upon and undertaken by them herein.

            SECTION 6.02. Merger or Consolidation of the Depositor or the Master
                          Servicer.

            The Depositor and the Master Servicer will each keep in full effect
its existence, rights and franchises as a corporation or association under the
laws of 


                                       66
<PAGE>   72

the United States or under the laws of one of the states thereof 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, or any of the
Mortgage Loans and to perform its respective duties under this Agreement.

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

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

            None of the Depositor, the Seller, the Master Servicer or any of the
directors, officers, employees or agents of the Depositor, the Seller or the
Master Servicer shall be under any liability to the Certificateholders for any
action taken or for refraining from the taking of any action in good faith
pursuant to this Agreement, or for errors in judgment; provided, however, that
this provision shall not protect the Depositor, the Seller, the Master Servicer
or any such Person against any breach of representations or warranties made by
it herein or protect the Depositor, the Seller, the Master Servicer or any such
Person from any liability which would otherwise be imposed by reasons of willful
misfeasance, bad faith or gross negligence in the performance of duties or by
reason of reckless disregard of obligations and duties hereunder. The Depositor,
the Seller, the Master Servicer and any director, officer, employee or agent of
the Depositor, the Seller or the Master Servicer may rely in good faith on any
document of any kind prima facie properly executed and submitted by any Person
respecting any matters arising hereunder. The Depositor, the Seller, the Master
Servicer and any director, officer, employee or agent of the Depositor, the
Seller 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
audit, controversy or judicial proceeding relating to a governmental taxing
authority or 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. None of the Depositor, the Seller or the
Master Servicer shall be under any obligation to appear in, prosecute or defend
any legal action that is not incidental to its respective duties hereunder and
which in its opinion may involve it in any expense or liability; provided,
however, that any of the Depositor, the Seller or the Master Servicer may in its
discretion undertake any such action that it may deem necessary or desirable in
respect of this Agreement and the rights and duties of the parties hereto and
interests of the Trustee and 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
Depositor, the Seller and the Master Servicer shall be entitled to be reimbursed
therefor out of the Certificate Account.

<PAGE>   73

            SECTION 6.04. Limitation on Resignation of Master Servicer.

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

                                   ARTICLE VII

                                     DEFAULT

            SECTION 7.01. Events of Default.

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

            be made under the terms of this Agreement, which failure shall
            continue unremedied for five days after the date upon which written
            notice of such failure shall have been given to the Master Servicer
            by the Trustee or the Depositor or to the Master Servicer and the
            Trustee by the Holders of Certificates having not less than 25% of
            the Voting Rights evidenced by the Certificates; or

            in any material respect any other of the covenants or agreements on
            the part of the Master Servicer contained in this Agreement, which
            failure shall continue unremedied for a period of 60 days after the
            date on which written notice of such failure shall have been given

            evidencing not less than 25% of the Voting Rights evidenced by the
            Certificates; or

                  (iii) a decree or order of a court or agency or supervisory
            authority having jurisdiction in the premises for the appointment of

            the winding-up or liquidation of its affairs, shall have been
            entered against the Master Servicer and such decree or order shall
            have remained in force undischarged or unstayed for a period of 60
            consecutive days; or

                  (iv) the Master Servicer shall consent to the appointment of a
            receiver or liquidator in any insolvency, readjustment of debt,
            marshalling of assets and liabilities or similar proceedings of or

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

                  (vi) so long as the Master Servicer is the Seller, any failure
            by the Seller to observe or perform in any material respect any
            other of the covenants or agreements on the part of the Seller
            contained in this Agreement, which failure shall continue unremedied

            such failure shall have been given to the Seller by the Trustee or
            the Depositor, or to the Seller and the Trustee by the Holders of
            Certificates evidencing not less than 25% of the Voting Rights
            evidenced by the Certificates; or

                  (vii) any failure of the Master Servicer to make any Advance
            in the manner and at the time required to be made pursuant to
            Section 4.01 which continues unremedied for a period of one Business
            Day after the date of such failure.

            If an Event of Default described in clauses (i) to (vi) of this
Section shall occur, then, and in each and every such case, so long as such
Event of Default shall not have been remedied, the Trustee may, or at the
direction of the Holders of Certificates evidencing not less than 25% of the
Voting Rights evidenced by the Certificates, the Trustee shall by notice in
writing to the Master Servicer (with a copy to each Rating Agency), terminate
all of the rights and obligations of the Master Servicer under this Agreement
and in and to the Mortgage Loans and the proceeds thereof, other than its rights
as a Certificateholder hereunder. If an Event of Default described in clause
(vii) hereof shall occur, the Trustee shall, by notice in writing to the Master
Servicer and the Depositor, terminate all of the rights and obligations of the
Master Servicer under this Agreement and in and to the Mortgage Loans and the
proceeds thereof, other than its rights as a Certificateholder hereunder. On and
after the receipt by the Master Servicer of such written notice, all authority
and power of the Master Servicer hereunder, whether with respect to the Mortgage
Loans or otherwise, shall pass to and be vested in the Trustee. The Trustee
shall thereupon make any Advance described in clause (vii) hereof subject to
Section 3.04 hereof. The Trustee is hereby authorized and empowered to execute
and deliver, on behalf of the Master Servicer, as attorney-in-fact or otherwise,
any and all documents and other instruments, and to do or accomplish all other
acts or things necessary or appropriate to effect the purposes of such notice of
termination, whether to complete the transfer and endorsement or assignment of
the Mortgage Loans and related documents, or otherwise. Unless expressly
provided in such written notice, no such termination shall affect any obligation
of the Master Servicer to pay amounts owed pursuant to Article VIII. The Master
Servicer agrees to cooperate with the Trustee in effecting the termination of
the Master Servicer's responsibilities and rights hereunder, including, without
limitation, the transfer to the Trustee of all cash amounts which shall at the
time be credited to the Certificate Account, or thereafter be received with
respect to the Mortgage Loans.

            Notwithstanding any termination of the activities of the Master
Servicer hereunder, the Master Servicer shall be entitled to receive, out of any
late collection of a Scheduled Payment on a Mortgage Loan which was due prior to
the notice terminating such Master Servicer's rights and obligations as Master
Servicer hereunder and received after such notice, that portion thereof to which
such Master Servicer would have been entitled pursuant to Sections 3.08(a)(i)
through (viii), and any 


                                       69
<PAGE>   75

other amounts payable to such Master Servicer hereunder the entitlement to which
arose prior to the termination of its activities hereunder.

            SECTION 7.02. Trustee to Act; Appointment of Successor.

            On and after the time the Master Servicer receives a notice of
termination pursuant to Section 7.01 hereof, the Trustee shall, subject to and
to the extent provided in Section 3.04, be the successor 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 and applicable law including the obligation to make
Advances pursuant to Section 4.01. As compensation therefor, the Trustee shall
be entitled to all funds relating to the Mortgage Loans that the Master Servicer
would have been entitled to charge to the Certificate Account or Distribution
Account if the Master Servicer had continued to act hereunder. Notwithstanding
the foregoing, if the Trustee has become the successor to the Master Servicer in
accordance with Section 7.01 hereof, the Trustee may, if it shall be unwilling
to so act, or shall, if it is prohibited by applicable law from making Advances
pursuant to Section 4.01 hereof or if it is otherwise unable to so act, appoint,
or petition a court of competent jurisdiction to appoint, any established
mortgage loan servicing institution the appointment of which does not adversely
affect the then current rating of the Certificates by each Rating Agency 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.
Any successor to the Master Servicer shall be an institution which is a FNMA and
FHLMC approved seller/servicer in good standing, which has a net worth of at
least $15,000,000, and which is willing to service the Mortgage Loans and
executes and delivers to the Depositor and the Trustee an agreement accepting
such delegation and assignment, which contains an assumption by such Person of
the rights, powers, duties, responsibilities, obligations and liabilities of the
Master Servicer (other than liabilities of the Master Servicer under Section
6.03 hereof incurred prior to termination of the Master Servicer under Section
7.01), with like effect as if originally named as a party to this Agreement; and
provided further that each Rating Agency acknowledges that its rating of the
Certificates in effect immediately prior to such assignment and delegation will
not be qualified or reduced as a result of such assignment and delegation.
Pending appointment of a successor to the Master Servicer hereunder, the
Trustee, unless the Trustee is prohibited by law from so acting, shall, subject
to Section 3.04 hereof, act in such capacity as hereinabove provided. In
connection with such appointment and assumption, the Trustee may make such
arrangements for the compensation of such successor out of payments on Mortgage
Loans as it and such successor shall agree; provided, however, that no such
compensation shall be in excess of the servicing compensation permitted the
Master Servicer hereunder. The Trustee and such successor shall take such
action, consistent with this Agreement, as shall be necessary to effectuate any
such succession. Neither the Trustee nor any other successor master servicer
shall be deemed to be in default hereunder by reason of any failure to make, or
any delay in making, any distribution hereunder or any portion thereof or any
failure to perform, or any delay in performing, any duties or responsibilities
hereunder, in either case caused by the failure of the Master Servicer to
deliver or provide, or any delay in delivering or providing, any cash,
information, documents or records to it.

            Any successor to the Master Servicer as master servicer shall give
notice to the Mortgagors of such change of servicer and shall, during the term
of its service as master servicer maintain in force the policy or policies that
the Master Servicer is required to maintain pursuant to Section 6.05.

            SECTION 7.03. Notification to Certificateholders.

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

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

                                  ARTICLE VIII

                             CONCERNING THE TRUSTEE

            SECTION 8.01. Duties of Trustee.

            The Trustee, prior to the occurrence of an Event of Default and
after the curing of all Events of Default that may have occurred, shall
undertake to perform such duties and only such duties as are specifically set
forth in this Agreement. In case an Event of Default has occurred and remains
uncured, 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 person would exercise or use under the circumstances in the conduct
of such person's own affairs.

            The Trustee, upon receipt of all resolutions, certificates,
statements, opinions, reports, documents, orders or other instruments furnished
to the Trustee that 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 resolution,
certificate, statement, opinion, report, document, order or other instrument.

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

                  (i) unless an Event of Default known to the Trustee shall have
            occurred and be continuing, 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 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 which it believed in good faith to be
            genuine and to have been duly executed by the proper authorities
            respecting any matters arising hereunder;

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


                                       71
<PAGE>   77

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

            SECTION 8.02. Certain Matters Affecting the Trustee.

            Except as otherwise provided in Section 8.01:

                  (i) the Trustee may request and rely upon and shall be
            protected in acting or refraining from acting upon any resolution,
            Officers' Certificate, certificate of auditors or any other
            certificate, statement, instrument, opinion, report, notice,
            request, consent, order, appraisal, bond or other paper or document
            believed by it to be genuine and to have been signed or presented by
            the proper party or parties and the Trustee shall have no
            responsibility to ascertain or confirm the genuineness of any
            signature of any such party or parties;

                  (ii) the Trustee may consult with counsel, financial advisers
            or accountants and the advice of any such counsel, financial
            advisers or accountants 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;

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

                  (iv) the Trustee shall not be bound to make any investigation
            into the facts or matters stated in any resolution, certificate,
            statement, instrument, opinion, report, notice, request, consent,
            order, approval, bond or other paper or document, unless requested
            in writing so to do by Holders of Certificates evidencing not less
            than 25% of the Voting Rights allocated to each Class of
            Certificates;

                  (v) the Trustee may execute any of the trusts or powers
            hereunder or perform any duties hereunder either directly or by or
            through agents, accountants or attorneys;

                  (vi) the Trustee shall not be required to risk or expend its
            own funds or otherwise incur any financial liability in the
            performance of any of its duties or in the exercise of any of its
            rights or powers hereunder if it shall have reasonable grounds for
            believing that repayment of such funds or adequate indemnity against
            such risk or liability is not assured to it;

                  (vii) the Trustee shall not be liable for any loss on any
            investment of funds pursuant to this Agreement (other than as issuer
            of the investment security);


                                       72
<PAGE>   78

                  (viii) the Trustee shall not be deemed to have knowledge of an
            Event of Default until a Responsible Officer of the Trustee shall
            have received written notice thereof; and

                  (ix) the Trustee shall be under no obligation to exercise any
            of the trusts, rights or powers vested in it by this Agreement or to
            institute, conduct or defend any litigation hereunder or in relation
            hereto at the request, order or direction of any of the
            Certificateholders, pursuant to the provisions of this Agreement,
            unless such Certificateholders shall have offered to the Trustee
            reasonable security or indemnity satisfactory to the Trustee against
            the costs, expenses and liabilities which may be incurred therein or
            thereby.

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

            The recitals contained herein and in the Certificates shall be taken
as the statements of the Depositor or the Seller, as the case may be, and the
Trustee assumes no responsibility for their correctness. The Trustee makes no
representations as to the validity or sufficiency of this Agreement or of the
Certificates or of any Mortgage Loan or related document other than with respect
to the Trustee's execution and counter-signature of the Certificates. The
Trustee shall not be accountable for the use or application by the Depositor or
the Master Servicer of any funds paid to the Depositor or the Master Servicer in
respect of the Mortgage Loans or deposited in or withdrawn from the Certificate
Account by the Depositor or the Master Servicer.

            SECTION 8.04. 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 as it would have if it

            SECTION 8.05. Trustee's Fees and Expenses.

            The Master Servicer agrees to pay the Trustee Fee to the Trustee, as
compensation for its activities hereunder. The Trustee and any director,
officer, employee or agent of the Trustee shall be indemnified by the Master
Servicer and held harmless against any loss, liability or expense (including
reasonable attorney's fees) (i) incurred in connection with any claim or legal
action relating to (a) this Agreement, (b) the Certificates or (c) in connection
with 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 and
(ii) resulting from any error in any tax or information return prepared by the
Master Servicer. Such indemnity shall survive the termination of this Agreement
or the resignation or removal of the Trustee hereunder. Without limiting the
foregoing, the Master Servicer covenants and agrees, except as otherwise agreed
upon in writing by the Depositor 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, to pay or 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 with respect to: (A) the
reasonable compensation and the expenses and disbursements of its counsel not
associated with the closing of the issuance of the Certificates, (B) the
reasonable compensation, expenses and disbursements of any accountant, engineer
or appraiser that is not regularly employed by the Trustee, to the extent that
the Trustee must engage such persons to perform acts or services hereunder and
(C) printing and engraving expenses in connection with preparing any Definitive
Certificates. Except as otherwise provided herein, the Trustee 


                                       73
<PAGE>   79

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
or Tax Matters Person or for any other expenses.

            SECTION 8.06. Eligibility Requirements for Trustee.

            The Trustee hereunder shall at all times be a corporation or
association organized and doing business under the laws of a state or the United
States of America, authorized under such laws to exercise corporate trust
powers, having a combined capital and surplus of at least $50,000,000, subject
to supervision or examination by federal or state authority and with a credit
rating which would not cause either of the Rating Agencies to reduce their
respective then current ratings of the Certificates (or having provided such
security from time to time as is sufficient to avoid such reduction). If such
corporation or 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 8.06 the combined capital and
surplus of such corporation or 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 provisions of this Section 8.06, the Trustee shall resign
immediately in the manner and with the effect specified in Section 8.07 hereof.
The entity serving as Trustee may have normal banking and trust relationships
with the Depositor and its affiliates or the Master Servicer and its affiliates;
provided, however, that such entity cannot be an affiliate of the Master
Servicer other than the Trustee in its role as successor to the Master Servicer.

            SECTION 8.07. Resignation and Removal of Trustee.

            The Trustee may at any time resign and be discharged from the trusts
hereby created by giving written notice of resignation to the Depositor and the
Master Servicer and each Rating Agency not less than 60 days before the date
specified in such notice when, subject to Section 8.08, such resignation is to
take effect, and acceptance by a successor trustee in accordance with Section
8.08 meeting the qualifications set forth in Section 8.06. If no successor
trustee meeting such qualifications shall have been so appointed and have
accepted appointment within 30 days after the giving of such notice or
resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor trustee.

            If at any time the Trustee shall cease to be eligible in accordance
with the provisions of Section 8.06 hereof and shall fail to resign after
written request thereto by the Depositor, or if at any time the Trustee shall
become incapable of acting, or shall be adjudged as bankrupt or insolvent, or a
receiver of the Trustee or of its property shall be appointed, or any public
officer shall take charge or control of the Trustee or of its property or
affairs for the purpose of rehabilitation, conservation or liquidation, or a tax
is imposed with respect to the Trust Fund by any state in which the Trustee or
the Trust Fund is located and the imposition of such tax would be avoided by the
appointment of a different trustee, then the Depositor or the Master Servicer
may remove the Trustee and appoint a successor trustee by written instrument, in
triplicate, one copy of which instrument shall be delivered to the Trustee, one
copy of which shall be delivered to the Master Servicer and one copy to the
successor trustee.

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

<PAGE>   80

            Any resignation or removal of the Trustee and appointment of a
successor trustee pursuant to any of the provisions of this Section 8.07 shall
become effective upon acceptance of appointment by the successor trustee as
provided in Section 8.08 hereof.

            SECTION 8.08. Successor Trustee.

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

            No successor trustee shall accept appointment as provided in this
Section 8.08 unless at the time of such acceptance such successor trustee shall
be eligible under the provisions of Section 8.06 hereof and its appointment
shall not adversely affect the then current rating of the Certificates.

            Upon acceptance of appointment by a successor trustee as provided in
this Section 8.08, the Depositor shall mail notice of the succession of such
trustee hereunder to all Holders of Certificates. If the Depositor fails to mail
such notice within 10 days after acceptance of appointment by the successor
trustee, the successor trustee shall cause such notice to be mailed at the
expense of the Depositor.

            SECTION 8.09. Merger or Consolidation of Trustee.

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

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

            Notwithstanding any other provisions of this Agreement, at any time,
for the purpose of meeting any legal requirements of any jurisdiction in which
any part of the Trust Fund or property securing any Mortgage Note may at the
time be located, the Master Servicer and the Trustee acting jointly shall have
the power and shall execute and deliver all instruments to appoint one or more
Persons approved by the Trustee to act as co-trustee or co-trustees jointly with
the Trustee, or separate trustee or separate trustees, of all or any part of the
Trust Fund, and to vest in such Person or Persons, in such capacity and for the
benefit of the Certificateholders, such title to the Trust Fund or any part
thereof, whichever is applicable, and, subject to the other provisions of this
Section 8.10, such powers, duties, obligations, rights and trusts as the Master
Servicer and the Trustee may consider necessary or desirable. If the Master
Servicer shall not have joined in such appointment within 15 days after the
receipt by it of a request to do so, or in the case an Event of Default shall
have occurred and be continuing, 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 8.06 and
no notice to 


                                       75
<PAGE>   81

Certificateholders of the appointment of any co-trustee or separate trustee
shall be required under Section 8.08.

            Every separate trustee and co-trustee shall, to the extent permitted
by law, be appointed and act subject to the following provisions and conditions:

                  (i) To the extent necessary to effectuate the purposes of this
            Section 8.10, all rights, powers, duties and obligations conferred
            or imposed upon the Trustee, except for the obligation of the
            Trustee under this Agreement to advance funds on behalf of the
            Master Servicer, shall be conferred or imposed upon and exercised or
            performed by the Trustee and such separate trustee or co-trustee
            jointly (it being understood that such separate trustee or
            co-trustee is not authorized to act separately without the Trustee
            joining in such act), 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 applicable
            Trust Fund or any portion thereof in any such jurisdiction) shall be
            exercised and performed singly by such separate trustee or
            co-trustee, but solely at the direction of the Trustee;

                  (ii) No trustee hereunder shall be held personally liable by
            reason of any act or omission of any other trustee hereunder and
            such appointment shall not, and shall not be deemed to, constitute
            any such separate trustee or co-trustee as agent of the Trustee;

                  (iii) The Trustee may at any time accept the resignation of or
            remove any separate trustee or co-trustee; and

                  (iv) The Master Servicer, and not the Trustee, shall be liable
            for the payment of reasonable compensation, reimbursement and
            indemnification to any such separate trustee or co-trustee.

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

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

            SECTION 8.11. Tax Matters.

            It is intended that the assets with respect to which any REMIC
election is to be made, as set forth in the Preliminary Statement, shall
constitute, and that the conduct of matters relating to such assets shall be
such as to qualify such assets as, a "real estate mortgage investment conduit"
as defined in and in accordance with the REMIC Provisions. In furtherance of
such intention, the Trustee covenants and agrees that it shall act as agent (and
the Trustee is hereby appointed to act as agent) on behalf of any such REMIC and
that in such capacity it shall: (a) prepare and file, or cause to be prepared
and filed, in a timely manner, a U.S. Real Estate Mortgage Investment Conduit
Income Tax Return (Form 1066 or any successor form adopted by the Internal
Revenue Service) and prepare and file or cause to be prepared and filed with the
Internal Revenue Service and applicable state or local tax authorities income
tax or information returns for each taxable year with respect to any such REMIC,
containing such information and at the times and in the manner as may be
required by the Code or state or local tax laws, regulations, or rules, and
furnish or cause to be furnished to Certificateholders the schedules, statements
or information at such times and in such manner as may be required thereby; (b)
within thirty days of the Closing Date, furnish or cause to be furnished to the
Internal Revenue Service, on Forms 8811 or as otherwise may be required by the
Code, the name, title, address, and telephone number of the person that the
holders of the Certificates may contact for tax information relating thereto,
together with such additional information as may be required by such Form, and
update such information at the time or times in the manner required by the Code;
(c) make or cause to be made elections that such assets be treated as a REMIC on
the federal tax return for its first taxable year (and, if necessary, under
applicable state law); (d) prepare and forward, or cause to be prepared and
forwarded, to the Certificateholders and to the Internal Revenue Service and, if
necessary, state tax authorities, all information returns and reports as and
when required to be provided to them in accordance with the REMIC Provisions,
including without limitation, the calculation of any original issue discount
using the Prepayment Assumption (as defined in the Prospectus Supplement); (e)
provide information necessary for the computation of tax imposed on the transfer
of a Residual Certificate to a Person that is not a Permitted Transferee, or an
agent (including a broker, nominee or other middleman) of a Non-Permitted
Transferee, or a pass-through entity in which a Non-Permitted Transferee is the
record holder of an interest (the reasonable cost of computing and furnishing
such information may be charged to the Person liable for such tax); (f) to the
extent that they are under its control conduct matters relating to such assets
at all times that any Certificates are outstanding so as to maintain the status
as a REMIC under the REMIC Provisions; (g) not knowingly or intentionally take
any action or omit to take any action that would cause the termination of the
REMIC status; (h) pay, from the sources specified in the last paragraph of this
Section 8.11, the amount of any federal or state tax, including prohibited
transaction taxes as described below, imposed on any such REMIC prior to its
termination when and as the same shall be due and payable (but such obligation
shall not prevent the Trustee or any other appropriate Person from contesting
any such tax in appropriate proceedings and shall not prevent the Trustee from
withholding payment of such tax, if permitted by law, pending the outcome of
such proceedings); (i) ensure that 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 laws, regulations
or rules; (j) maintain records relating to any such REMIC, including but not
limited to the income, expenses, assets and liabilities thereof and the fair
market value and adjusted basis of the 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; and (k) as and when necessary and
appropriate, represent any such REMIC in any administrative or judicial
proceedings relating to an examination or audit by any governmental taxing
authority, request an administrative adjustment as to any taxable year of any
such REMIC, enter into settlement agreements with any governmental taxing
agency, extend any statute of limitations relating to any tax item of any 


                                       77
<PAGE>   83

such REMIC, and otherwise act on behalf of any such REMIC in relation to any tax
matter or controversy involving it.

            In order to enable the Trustee to perform its duties as set forth
herein, the Depositor shall provide, or cause to be provided, to the Trustee
within ten (10) days after the Closing Date all information or data that the
Trustee requests in writing and determines to be relevant for tax purposes to
the valuations and offering prices of the Certificates, including, without
limitation, the price, yield, prepayment assumption and projected cash flows of
the Certificates and the Mortgage Loans. Thereafter, the Depositor shall provide
to the Trustee promptly upon written request therefor, any such additional
information or data that the Trustee may, from time to time, reasonably request
in order to enable the Trustee to perform its duties as set forth herein. The
Depositor hereby indemnifies the Trustee for any losses, liabilities, damages,
claims or expenses of the Trustee arising from any errors or miscalculations of
the Trustee that result from any failure of the Depositor to provide, or to
cause to be provided, accurate information or data to the Trustee on a timely
basis.

            In the event that any tax is imposed on "prohibited transactions" of
the REMIC as defined in Section 860F(a)(2) of the Code, on the "net income from
foreclosure property" of the REMIC as defined in Section 860G(c) of the Code, on
any contribution to the REMIC after the Startup Day pursuant to Section 860G(d)
of the Code, or any other tax is imposed, including, without limitation, any
minimum tax imposed upon the REMIC pursuant to Sections 23153 and 24874 of the
California Revenue and Taxation Code, if not paid as otherwise provided for
herein, such tax shall be paid by (i) the Trustee, if any such other tax arises
out of or results from a breach by the Trustee of any of its obligations under
this Agreement, (ii) the Master Servicer, in the case of any such minimum tax,
or if such tax arises out of or results from a breach by the Master Servicer or
Seller of any of their obligations under this Agreement, (iii) the Seller, if
any such tax arises out of or results from the Seller's obligation to repurchase
a Mortgage Loan pursuant to Section 2.02 or 2.03 or (iv) in all other cases, or
in the event that the Trustee, the Master Servicer or the Seller fails to honor
its obligations under the preceding clauses (i),(ii) or (iii), any such tax will
be paid with amounts otherwise to be distributed to the Certificateholders, as
provided in Section 3.08(b).

            SECTION 8.12. Periodic Filings.

            Pursuant to written instructions from the Depositor, the Trustee
shall prepare, execute and file all periodic reports required under the
Securities Exchange Act of 1934 in connection with this Agreement (other than
any such reports due as a result of the original issuance of the Certificates).
In connection with the preparation and filing of such periodic reports, the
Depositor and the Master Servicer shall timely provide to the Trustee all
material information available to them which is required to be included in such
reports and not known to them to be in the possession of the Trustee and such
other information as the Trustee reasonably may request from either of them and
otherwise reasonably shall cooperate with the Trustee. The Trustee shall have no
liability with respect to any failure to properly prepare or file such periodic
reports resulting from or relating to the Trustee's inability or failure to
obtain any information not resulting from its own negligence or willful
misconduct.

                                   ARTICLE IX

                                   TERMINATION

            SECTION 9.01. Termination upon Liquidation or Purchase of all
                          Mortgage Loans.

            Subject to Section 9.03, the obligations and responsibilities of the
Depositor, the Master Servicer and the Trustee created hereby with respect to
the Trust Fund shall terminate upon the earlier of (a) the purchase by the
Master Servicer of all Mortgage Loans (and REO Properties) remaining in the
Trust Fund at the price equal to the sum of (i) 100% of the Stated Principal
Balance of each Mortgage Loan plus one month's accrued interest thereon at the
applicable Adjusted Mortgage Rate and (ii) the lesser of (x) the appraised value
of any REO Property as determined by the higher of two appraisals completed by
two independent appraisers selected by the Master Servicer at the expense of the
Master Servicer and (y) the Stated Principal Balance of each Mortgage Loan
related to any REO Property, in each case plus accrued and unpaid interest
thereon at the applicable Adjusted Mortgage Rate and (b) the later of (i) the
maturity or other liquidation (or any Advance with respect thereto) of the last
Mortgage Loan remaining in the Trust Fund and the disposition of all REO
Property and (ii) the distribution to Certificateholders of all amounts required
to be distributed to them pursuant to this Agreement. In no event shall the
trusts created hereby continue beyond the earlier of (i) the expiration of 21
years from the death of the survivor of the descendants of Joseph P. Kennedy,
the late Ambassador of the United States to the Court of St. James's, living on
the date hereof and (ii) the Latest Possible Maturity Date. The right to
purchase all Mortgage Loans and REO Properties pursuant to clause (a) above
shall be conditioned upon the Pool Stated Principal Balance, at the time of any
such repurchase, aggregating less than ten percent of the aggregate Cut-off Date
Principal Balance of the Mortgage Loans.

            SECTION 9.02. Final Distribution on the Certificates.

            If on any Determination Date, the Master Servicer determines that
there are no Outstanding Mortgage Loans and no other funds or assets in the
Trust Fund other than the funds in the Certificate Account, the Master Servicer
shall direct the Trustee promptly to send a final distribution notice to each
Certificateholder. If the Master Servicer elects to terminate the Trust Fund
pursuant to clause (a) of Section 9.01, at least 20 days prior to the date
notice is to be mailed to the affected Certificateholders, the Master Servicer
shall notify the Depositor and the Trustee of the date the Master Servicer
intends to terminate the Trust Fund and of the applicable repurchase price of
the Mortgage Loans and REO Properties.

            Notice of any termination of the Trust Fund, specifying the
Distribution Date on which Certificateholders may surrender their Certificates
for payment of the final distribution and cancellation, shall be given to the
extent reasonably practicable by the Trustee by letter to Certificateholders
mailed not earlier than the 15th day and no later than the 10th day of the month
next preceding the month of such final distribution. Any such notice shall
specify (a) the Distribution Date upon which final distribution on the
Certificates will be made upon presentation and surrender of Certificates at the
office therein designated, (b) the amount of such final distribution, (c) the
location of the office or agency at which such presentation and surrender must
be made, and (d) that the Record Date otherwise applicable to such Distribution
Date is not applicable, distributions being made only upon presentation and
surrender of the Certificates at the office therein specified. The Master
Servicer will give such notice to each Rating Agency at the time such notice is
given to Certificateholders.


                                       79
<PAGE>   85

            In the event such notice is given, the Master Servicer shall cause
all funds in the Certificate Account to be remitted to the Trustee for deposit
in the Distribution Account on the Business Day prior to the applicable
Distribution Date. Upon such final deposit with respect to the Trust Fund and
the receipt by the Trustee of a Request for Release therefor, the Trustee shall
promptly release to the Master Servicer the Mortgage Files for the Mortgage
Loans.

            Upon presentation and surrender of the Certificates, the Trustee
shall cause to be distributed to the Certificateholders of each Class, in the
order set forth in Section 4.02 hereof, on the final Distribution Date, 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
Regular Certificates, the Certificate Balance thereof plus accrued interest
thereon (or on their Notional Amount, if applicable) in the case of an interest
bearing Certificate, and (ii) as to the Residual 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.

            In the event that any affected Certificateholders shall not
surrender Certificates for cancellation within six months after the date
specified in the above mentioned written notice, the Trustee 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 six months after the second notice all the applicable
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 and other
assets which remain a part of the Trust Fund. If within one year after the
second notice all Certificates shall not have been surrendered for cancellation,
the Class A-R Certificateholders shall be entitled to all unclaimed funds and
other assets of the Trust Fund which remain subject hereto.

            SECTION 9.03. Additional Termination Requirements.

            (a) In the event the Master Servicer exercises its purchase option
as provided in Section 9.01, the Trust Fund shall be terminated in accordance
with the following additional requirements, unless the Trustee has been supplied
with an Opinion of Counsel, at the expense of the Master Servicer, to the effect
that the failure to comply with the requirements of this Section 9.03 will not
(i) result in the imposition of taxes on "prohibited transactions" on any REMIC
as defined in section 860F of the Code, or (ii) cause any REMIC hereunder to
fail to qualify as a REMIC at any time that any Certificates are outstanding:

            (1) Within 90 days prior to the final Distribution Date set forth in
      the notice given by the Master Servicer under Section 9.02, the Master
      Servicer shall prepare and the Trustee, at the expense of the "tax matters
      person," shall adopt a plan of complete liquidation within the meaning of
      section 860F(a)(4) of the Code which, as evidenced by an Opinion of
      Counsel (which opinion shall not be an expense of the Trustee or the Tax
      Matters Person), meets the requirements of a qualified liquidation; and

            (2) Within 90 days after the time of adoption of such a plan of
      complete liquidation, the Trustee shall sell all of the assets of the
      Trust Fund to the Master Servicer for cash in accordance with Section
      9.01.

            (b) The Trustee as agent for any REMIC hereby agrees to adopt and
sign such a plan of complete liquidation upon the written request of the Master
Servicer, and the receipt of the Opinion of 


                                       80
<PAGE>   86

Counsel referred to in Section 9.03(a)(1) and to take such other action in
connection therewith as may be reasonably requested by the Master Servicer.

            (c) By their acceptance of the Certificates, the Holders thereof
hereby authorize the Master Servicer to prepare and the Trustee to adopt and
sign a plan of complete liquidation.

                                    ARTICLE X

                            MISCELLANEOUS PROVISIONS

            SECTION 10.01. Amendment.

            This Agreement may be amended from time to time by the Depositor,
the Master Servicer and the Trustee without the consent of any of the
Certificateholders to cure any ambiguity or defect, or to correct or supplement
any provisions herein, (including to give effect to the expectations of
investors), or to make such other provisions with respect to matters or
questions arising under this Agreement as shall not be inconsistent with any
other provisions herein; provided that such action shall not, as evidenced by an
Opinion of Counsel (which Opinion of Counsel shall not be an expense of the
Trustee or the Trust Fund), adversely affect in any material respect the
interests of any Certificateholder; provided, however, that the amendment shall
not be deemed to adversely affect in any material respect the interests of the
Certificateholders 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; it being understood and agreed that any such letter in and of
itself will not represent a determination as to the materiality of any such
amendment and will represent a determination only as to the credit issues
affecting any such rating. The Trustee, the Depositor and the Master Servicer
also may at any time and from time to time amend this Agreement without the
consent of the Certificateholders to modify, eliminate or add to any of its
provisions to such extent as shall be necessary or helpful to maintain the
qualification of any REMIC hereunder as a REMIC under the Code or to avoid or
minimize the risk of the imposition of any tax on any REMIC hereunder pursuant
to the Code that would be a claim at any time prior to the final redemption of
the Certificates, provided that the Trustee has been provided an Opinion of
Counsel, which opinion shall be an expense of the party requesting such opinion
but in any case shall not be an expense of the Trustee or the Trust Fund, to the
effect that such action is necessary or helpful to maintain such qualification
or to avoid or minimize the risk of the imposition of such a tax.

            This Agreement may also be amended from time to time by the
Depositor, the Master Servicer and the Trustee with the consent of the Holders
of a Majority in Interest of each Class of Certificates affected thereby for the
purpose of adding any provisions to or changing in any manner or eliminating any
of the provisions of this Agreement or of modifying in any manner the rights of
the Holders of Certificates; provided, however, that no such amendment shall (i)
reduce in any manner the amount of, or delay the timing of, payments required to
be distributed on any Certificate without the consent of the Holder of such
Certificate, (ii) adversely affect in any material respect the interests of the
Holders of any Class of Certificates in a manner other than as described in (i),
without the consent of the Holders of Certificates of such Class evidencing, as
to such Class, Percentage Interests aggregating 66% or (iii) reduce the
aforesaid percentages of Certificates the Holders of which are required to
consent to any such amendment, without the consent of the Holders of all such
Certificates then outstanding.

            Notwithstanding any contrary provision of this Agreement, the
Trustee shall not consent to any amendment to this Agreement unless it shall
have first received an Opinion of Counsel, which 


                                       81
<PAGE>   87

opinion shall not be an expense of the Trustee or the Trust Fund, to the effect
that such amendment will not cause the imposition of any tax on any REMIC
hereunder or the Certificateholders or cause any REMIC hereunder to fail to
qualify as a REMIC at any time that any Certificates are outstanding.

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

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

            Nothing in this Agreement shall require the Trustee to enter into an
amendment without receiving an Opinion of Counsel (which Opinion shall not be an
expense of the Trustee or the Trust Fund, satisfactory to the Trustee that (i)
such amendment is permitted and is not prohibited by this Agreement and that all
requirements for amending this Agreement have been complied with; and (ii)
either (A) the amendment does not adversely affect in any material respect the
interests of any Certificateholder or (B) the conclusion set forth in the
immediately preceding clause (A) is not required to be reached pursuant to this
Section 10.01.

            SECTION 10.02. Recordation of Agreement; Counterparts.

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

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

            SECTION 10.03. Governing Law.

            THIS AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY
THE SUBSTANTIVE LAWS OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND
TO BE PERFORMED IN THE STATE OF NEW YORK AND THE OBLIGATIONS, RIGHTS AND
REMEDIES OF THE PARTIES HERETO AND THE CERTIFICATEHOLDERS SHALL BE DETERMINED IN
ACCORDANCE WITH SUCH LAWS.

            SECTION 10.04. Intention of Parties.

            It is the express intent of the parties hereto that the conveyance
of the Trust Fund by the Depositor to the Trustee be, and be construed as, an
absolute sale thereof to the Trustee. It is, further, not 


                                       82
<PAGE>   88

the intention of the parties that such conveyance be deemed a pledge thereof by
the Depositor to the Trustee. However, in the event that, notwithstanding the
intent of the parties, such assets are held to be the property of the Depositor,
or if for any other reason this Agreement is held or deemed to create a security
interest in 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 conveyance provided for in this Agreement shall
be deemed to be an assignment and a grant by the Depositor to the Trustee, for
the benefit of the Certificateholders, of a security interest in all of the
assets that constitute the Trust Fund, whether now owned or hereafter acquired.

            The Depositor for the benefit of the Certificateholders shall, to
the extent consistent with this Agreement, take such actions as may be necessary
to ensure that, if this Agreement were deemed to create a security interest in
the Trust Fund, such security interest would be deemed to be a perfected
security interest of first priority under applicable law and will be maintained
as such throughout the term of the Agreement.

            SECTION 10.05. Notices.

            (a) The Trustee shall use its best efforts to promptly provide
notice to each Rating Agency with respect to each of the following of which it
has actual knowledge:

            1. Any material change or amendment to this Agreement;

            2. The occurrence of any Event of Default that has not been cured;

            3. The resignation or termination of the Master Servicer or the
      Trustee and the appointment of any successor;

            4. The repurchase or substitution of Mortgage Loans pursuant to
      Section 2.03; and

            5. The final payment to Certificateholders.

Rights evidenced by the Certificates shall also have made written request to the
Trustee to institute such action, suit or proceeding in its own name as Trustee

Servicer hereby authorizes said accountants to discuss with such representative
such affairs, finances and accounts), all at such reasonable times and as often
as may be reasonably requested. Any out-of-pocket expense incident to the
exercise by the Depositor or the Trustee of any right under this Section 10.09

                       Mortgage Pass-Through Certificates
                                  Series 1998-1

          Representations and Warranties of the Seller/Master Servicer

            Mellon Mortgage Company ("MMC") hereby makes the representations and
warranties set forth in this Schedule II to the Depositor and the Trustee, as of
the Closing Date, or if so specified herein, as of the Cut-off Date. Capitalized
terms used but not otherwise defined in this Schedule II shall have the meanings
ascribed thereto in the Pooling and Servicing Agreement (the "Pooling and
Servicing Agreement") relating to the above-referenced Series, among MMC, as
seller and master servicer, Mellon Residential Funding Corporation, as
depositor, and Bankers Trust Company of California, N.A., as trustee.

            (1) MMC is duly organized as a Colorado corporation and is validly
      existing and in good standing under the laws of the State of Colorado and
      is duly authorized and qualified to transact any and all business
      contemplated by the Pooling and Servicing Agreement to be conducted by MMC
      in any state in which a Mortgaged Property is located or is otherwise not
      required under applicable law to effect such qualification and, in any
      event, is in compliance with the doing business laws of any such state, to
      the extent necessary to ensure its ability to enforce each Mortgage Loan,
      to service the Mortgage Loans in accordance with the terms of the Pooling
      and Servicing Agreement and to perform any of its other obligations under
      the Pooling and Servicing Agreement in accordance with the terms thereof.

            (2) MMC has the full corporate power and authority to sell and
      service each Mortgage Loan, and to execute, deliver and perform, and to
      enter into and consummate the transactions contemplated by the Pooling and
      Servicing Agreement and has duly authorized by all necessary corporate
      action on the part of MMC the execution, delivery and performance of the
      Pooling and Servicing Agreement; and the Pooling and Servicing Agreement,
      assuming the due authorization, execution and delivery thereof by the
      other parties thereto, constitutes a legal, valid and binding obligation
      of MMC, enforceable against MMC in accordance with its terms, except that
      (a) the enforceability thereof may be limited by bankruptcy, insolvency,
      moratorium, receivership and other similar laws relating to creditors'
      rights generally and (b) the remedy of specific performance and injunctive
      and other forms of equitable relief may be subject to equitable defenses
      and to the discretion of the court before which any proceeding therefor
      may be brought.

            (3) The execution and delivery of the Pooling and Servicing
      Agreement by MMC, the sale and servicing of the Mortgage Loans by MMC
      under the Pooling and Servicing Agreement, the consummation of any other
      of the transactions contemplated by the Pooling and Servicing Agreement,
      and the fulfillment of or compliance with the terms thereof are in the
      ordinary course of business of MMC and will not (A) result in a material
      breach of any term or provision of the charter or by-laws of MMC or (B)
      materially conflict with, result in a material breach, violation or
      acceleration of, or result in a material default under, the terms of any
      other material agreement or instrument to which MMC is a party or by which
      it may be bound, or (C) 


                                      II-1
<PAGE>   94

      constitute a material violation of any statute, order or regulation
      applicable to MMC of any court, regulatory body, administrative agency or
      governmental body having jurisdiction over MMC; and MMC is not in breach
      or violation of any material indenture or other material agreement or
      instrument, or in violation of any statute, order or regulation of any
      court, regulatory body, administrative agency or governmental body having
      jurisdiction over it which breach or violation may materially impair MMC's
      ability to perform or meet any of its obligations under the Pooling and
      Servicing Agreement.

            (4) MMC is an approved servicer of conventional mortgage loans for
      FNMA or FHLMC and is a mortgagee approved by the Secretary of Housing and
      Urban Development pursuant to sections 203 and 211 of the National Housing
      Act.

            (5) No litigation is pending or, to the best of MMC's knowledge,
      threatened, against MMC that would materially and adversely affect the
      execution, delivery or enforceability of the Pooling and Servicing
      Agreement or the ability of MMC to sell or service the Mortgage Loans or
      to perform any of its other obligations under the Pooling and Servicing
      Agreement in accordance with the terms thereof.

            (6) No consent, approval, authorization or order of any court or
      governmental agency or body is required for the execution, delivery and
      performance by MMC of, or compliance by MMC with, the Pooling and
      Servicing Agreement or the consummation of the transactions contemplated
      thereby, or if any such consent, approval, authorization or order is
      required, MMC has obtained the same.

            (7) MMC intends to treat the transfer of the Mortgage Loans to the
      Depositor as a sale of the Mortgage Loans for all tax, accounting and
      regulatory purposes.

                                  SCHEDULE III

                     Mellon Residential Funding Corporation
                       Mortgage Pass-Through Certificates
                                  Series 1998-1

             Representations and Warranties as to the Mortgage Loans

            Mellon Mortgage Company ("MMC") hereby makes the representations and
warranties set forth in this Schedule III to the Depositor and the Trustee, as
of the Closing Date, or if so specified herein, as of the Cut-off Date.
Capitalized terms used but not otherwise defined in this Schedule III shall have
the meanings ascribed thereto in the Pooling and Servicing Agreement (the
"Pooling and Servicing Agreement") relating to the above-referenced Series,
among MMC, as seller and master servicer, Mellon Residential Funding
Corporation, as depositor, and Bankers Trust Company of California, N.A., as
trustee.

            (1) The information set forth on Schedule I to the Pooling and
      Servicing Agreement with respect to each Mortgage Loan is true and correct
      in all material respects as of the Closing Date

            (2) As of the Closing Date, all payments due with respect to each
      Mortgage Loan prior to the Cut-off Date have been made; and as of the
      Cut-off Date, no Mortgage Loan has been contractually delinquent for 30 or
      more days during the twelve months prior to the Cut-off Date.

            (3) No Mortgage Loan had a Loan-to-Value Ratio at origination in
      excess of 95%.

            (4) Each Mortgage is a valid and enforceable first lien on the
      Mortgaged Property subject only to (a) the lien of non delinquent current
      real property taxes and assessments, (b) covenants, conditions and
      restrictions, rights of way, easements and other matters of public record
      as of the date of recording of such Mortgage, such exceptions appearing of
      record being acceptable to mortgage lending institutions generally or
      specifically reflected in the appraisal made in connection with the
      origination of the related Mortgage Loan, and (c) other matters to which
      like properties are commonly subject which do not materially interfere
      with the benefits of the security intended to be provided by such
      Mortgage.

            (5) Immediately prior to the assignment of the Mortgage Loans to the
      Depositor, the Seller had good title to, and was the sole owner of, each
      Mortgage Loan free and clear of any pledge, lien, encumbrance or security
      interest and had full right and authority, subject to no interest or
      participation of, or agreement with, any other party, to sell and assign
      the same pursuant to the Pooling and Servicing Agreement.

            (6) There is no delinquent tax or assessment lien against any
      Mortgaged Property.

            (7) There is no valid offset, defense or counterclaim to any
      Mortgage Note or Mortgage, including the obligation of the Mortgagor to
      pay the unpaid principal of or interest on such Mortgage Note.


                                     III-1
<PAGE>   96

            (8) There are no mechanics' liens or claims for work, labor or
      material affecting any Mortgaged Property which are or may be a lien prior
      to, or equal with, the lien of such Mortgage, except those which are
      insured against by the title insurance policy referred to in item (12)
      below.

            (9) To the best of the Seller's knowledge, each Mortgaged Property
      is free of material damage and in good repair.

            (10) Each Mortgage Loan at origination complied in all material
      respects with applicable state and federal laws, including, without
      limitation, usury, equal credit opportunity, real estate settlement
      procedures, truth-in-lending and disclosure laws, and consummation of the
      transactions contemplated hereby will not involve the violation of any
      such laws.

            (11) As of the Closing Date, neither the Seller nor any prior holder
      of any Mortgage has modified the Mortgage in any material respect (except
      that a Mortgage Loan may have been modified by a written instrument which
      has been recorded or submitted for recordation, if necessary, to protect
      the interests of the Certificateholders and the original or a copy of
      which has been delivered to the Trustee); satisfied, cancelled or
      subordinated such Mortgage in whole or in part; released the related
      Mortgaged Property in whole or in part from the lien of such Mortgage; or
      executed any instrument of release, cancellation, modification or
      satisfaction with respect thereto.

            (12) A lender's policy of title insurance together with a
      condominium endorsement and extended coverage endorsement, if applicable,
      in an amount at least equal to the Cut-off Date Stated Principal Balance
      of each such Mortgage Loan or a commitment (binder) to issue the same was
      effective on the date of the origination of each Mortgage Loan, each such
      policy is valid and remains in full force and effect, and each such policy
      was issued by a title insurer qualified to do business in the jurisdiction
      where the Mortgaged Property is located and acceptable to FNMA or FHLMC
      and is in a form acceptable to FNMA or FHLMC, which policy insures the
      Seller and successor owners of indebtedness secured by the insured
      Mortgage, as to the first priority lien of the Mortgage subject to the
      exceptions set forth in paragraph (4) above; to the best of the Seller's
      knowledge, no claims have been made under such mortgage title insurance
      policy and no prior holder of the related Mortgage, including the Seller,
      has done, by act or omission, anything which would impair the coverage of
      such mortgage title insurance policy.

            (13) Each Mortgage Loan was originated by an entity that satisfied
      at the time of origination the requirements of Section 3(a)(41) of the
      Securities Exchange Act of 1934, as amended.

            (14) To the best of the Seller's knowledge, all of the improvements
      which were included for the purpose of determining the Appraised Value of
      the Mortgaged Property lie wholly within the boundaries and building
      restriction lines of such property, and no improvements on adjoining
      properties encroach upon the Mortgaged Property.

            (15) To the best of the Seller's knowledge, no improvement located
      on or being part of the Mortgaged Property is in violation of any
      applicable zoning law or regulation. To the best 


                                     III-2
<PAGE>   97

      of the Seller's knowledge, all inspections, licenses and certificates
      required to be made or issued with respect to all occupied portions of the
      Mortgaged Property and, with respect to the use and occupancy of the same,
      including but not limited to certificates of occupancy and fire
      underwriting certificates, have been made or obtained from the appropriate
      authorities, unless the lack thereof would not have a material adverse
      effect on the value of such Mortgaged Property, and the Mortgaged Property
      is lawfully occupied under applicable law.

            (16) The Mortgage Note and the related Mortgage are genuine, and
      each is the legal, valid and binding obligation of the maker thereof,
      enforceable in accordance with its terms and under applicable law. To the
      best of the Seller's knowledge, all parties to the Mortgage Note and the
      Mortgage had legal capacity to execute the Mortgage Note and the Mortgage
      and each Mortgage Note and Mortgage have been duly and properly executed
      by such parties.

            (17) The proceeds of the Mortgage Loan have been fully disbursed,
      there is no requirement for future advances thereunder and any and all
      requirements as to completion of any on-site or off-site improvements and
      as to disbursements of any escrow funds therefor have been complied with.
      All costs, fees and expenses incurred in making, or closing or recording
      the Mortgage Loans were paid.

            (18) The related Mortgage contains customary and enforceable
      provisions which render the rights and remedies of the holder thereof
      adequate for the realization against the Mortgaged Property of the
      benefits of the security, including, (i) in the case of a Mortgage
      designated as a deed of trust, by trustee's sale, and (ii) otherwise by
      judicial foreclosure.

            (19) With respect to each Mortgage constituting a deed of trust, a
      trustee, duly qualified under applicable law to serve as such, has been
      properly designated and currently so serves and is named in such Mortgage,
      and no fees or expenses are or will become payable by the
      Certificateholders to the trustee under the deed of trust, except in
      connection with a trustee's sale after default by the Mortgagor.

            (20) Each Mortgage Note and each Mortgage is in substantially one of
      the forms acceptable to FNMA or FHLMC, with such riders as have been
      acceptable to FNMA or FHLMC, as the case may be.

            (21) There exist no deficiencies with respect to escrow deposits and
      payments, if such are required, for which customary arrangements for
      repayment thereof have not been made, and no escrow deposits or payments
      of other charges or payments due the Seller have been capitalized under
      the Mortgage or the related Mortgage Note.

            (22) The origination, underwriting and collection practices used by
      the Seller with respect to each Mortgage Loan have been in all respects
      legal, prudent and customary in the mortgage lending and servicing
      business.

            (23) There is no pledged account or other security other than real
      estate securing the Mortgagor's obligations.


                                     III-3
<PAGE>   98

            (24) No Mortgage Loan has a shared appreciation feature, or other
      contingent interest feature.

            (25) Each Mortgage Loan contains a customary "due on sale" clause.

            (26) None of the Mortgage Loans provides for a prepayment penalty.

            (27) Each Mortgage Loan which had a Loan-to-Value Ratio at
      origination in excess of 80% is the subject of a Primary Insurance Policy
      that insures that portion of the principal balance thereof that exceeds
      the amount equal to 75% of the Appraised Value of the related Mortgaged
      Property. Each such Primary Insurance Policy is issued by a Qualified
      Insurer. All provisions of any such Primary Insurance Policy have been and
      are being complied with, any such policy is in full force and effect, and
      all premiums due thereunder have been paid. Any Mortgage subject to any
      such Primary Insurance Policy obligates either the Mortgagor or the
      mortgagee thereunder to maintain such insurance and to pay all premiums
      and charges in connection therewith. The Mortgage Rate for each Mortgage
      Loan is net of any such insurance premium.

            (28) At the Cut-off Date, the improvements upon each Mortgaged
      Property are covered by a valid and existing hazard insurance policy with
      a generally acceptable carrier that provides for fire and extended
      coverage and coverage for such other hazards as are customary in the area
      where the Mortgaged Property is located in an amount which is at least
      equal to the lesser of (i) the maximum insurable value of the improvements
      securing such Mortgage Loan or (ii) the greater of (a) the outstanding
      principal balance of the Mortgage Loan and (b) an amount such that the
      proceeds of such policy shall be sufficient to prevent the Mortgagor
      and/or the mortgagee from becoming a co-insurer. If the Mortgaged Property
      is a condominium unit, it is included under the coverage afforded by a
      blanket policy for the condominium unit. All such individual insurance
      policies and all flood policies referred to in item (29) below contain a
      standard mortgagee clause naming the Seller or the original mortgagee, and
      its successors in interest, as mortgagee, and the Seller has received no
      notice that any premiums due and payable thereon have not been paid; the
      Mortgage obligates the Mortgagor thereunder to maintain all such insurance
      including flood insurance at the Mortgagor's cost and expense, and upon
      the Mortgagor's failure to do so, authorizes the holder of the Mortgage to
      obtain and maintain such insurance at the Mortgagor's cost and expense and
      to seek reimbursement therefor from the Mortgagor.

            (29) If the Mortgaged Property is in an area identified in the
      Federal Register by the Federal Emergency Management Agency as having
      special flood hazards, a flood insurance policy in a form meeting the
      requirements of the current guidelines of the Flood Insurance
      Administration is in effect with respect to such Mortgaged Property with a
      generally acceptable carrier in an amount representing coverage not less
      than the least of (A) the original outstanding principal balance of the
      Mortgage Loan, (B) the minimum amount required to compensate for damage or
      loss on a replacement cost basis, or (C) the maximum amount of insurance
      that is available under the Flood Disaster Protection Act of 1973, as
      amended.

            (30) To the best of the Seller's knowledge, there is no proceeding
      occurring, pending or threatened for the total or partial condemnation of
      the Mortgaged Property.


                                     III-4
<PAGE>   99

            (31) There is no material monetary default existing under any
      Mortgage or the related Mortgage Note and, to the best of the Seller's
      knowledge, there is no material event which, with the passage of time or
      with notice and the expiration of any grace or cure period, would
      constitute a default, breach, violation or event of acceleration under the
      Mortgage or the related Mortgage Note; and the Seller has not waived any
      default, breach, violation or event of acceleration.

            (32) Each Mortgaged Property is improved by a one- to four-family
      residential dwelling including condominium units and dwelling units in
      PUDs, which, to the best of Seller's knowledge, does not include
      cooperatives or mobile homes and does not constitute other than real
      property under state law.

            (33) Each Mortgage Loan is being serviced by the Master Servicer.

            (34) Any future advances made prior to the Cut-off Date have been
      consolidated with the outstanding principal amount secured by the
      Mortgage, and the secured principal amount, as consolidated, bears a
      single interest rate and single repayment term reflected on the Mortgage
      Loan Schedule. The consolidated principal amount does not exceed the
      original principal amount of the Mortgage Loan. The Mortgage Note does not
      permit or obligate the Master Servicer to make future advances to the
      Mortgagor at the option of the Mortgagor.

            (35) All taxes, governmental assessments, insurance premiums, water,
      sewer and municipal charges, leasehold payments or ground rents which
      previously became due and owing have been paid, or an escrow of funds has
      been established in an amount sufficient to pay for every such item which
      remains unpaid and which has been assessed, but is not yet due and
      payable. Except for (A) payments in the nature of escrow payments, and (B)
      interest accruing from the date of the Mortgage Note or date of
      disbursement of the Mortgage proceeds, whichever is later, to the day
      which precedes by one month the Due Date of the first installment of
      principal and interest, including without limitation, taxes and insurance
      payments, the Master Servicer has not advanced funds, or induced,
      solicited or knowingly received any advance of funds by a party other than
      the Mortgagor, directly or indirectly, for the payment of any amount
      required by the Mortgage.

            (36) Each Mortgage Loan was underwritten in all material respects in
      accordance with the Seller's underwriting guidelines as set forth in the
      Prospectus Supplement.

            (37) Prior to the approval of the Mortgage Loan application, an
      appraisal of the related Mortgaged Property was obtained from a qualified
      appraiser, duly appointed by the originator, who had no interest, direct
      or indirect, in the Mortgaged Property or in any loan made on the security
      thereof, and whose compensation is not affected by the approval or
      disapproval of the Mortgage Loan; such appraisal is in a form acceptable
      to FNMA and FHLMC.

            (38) None of the Mortgage Loans is a graduated payment mortgage loan
      or a growing equity mortgage loan and none of the Mortgage Loans are
      subject to a buydown or similar arrangement.


                                     III-5
<PAGE>   100

            (39) Any leasehold estate securing a Mortgage Loan has a term of not
      less than five years in excess of the term of the related Mortgage Loan.

            (40) The Mortgage Loans were selected from among the outstanding
      fixed-rate one- to four-family mortgage loans in the Seller's portfolio at
      the Closing Date as to which the representations and warranties made as to
      the Mortgage Loans set forth in this Schedule III can be made. Such
      selection was not made in a manner that would adversely affect the
      interests of Certificateholders.

            (41) Except for 0 Mortgage Loans, each Mortgage Loan has a payment
      date on or before the Due Date in the month of the first Distribution
      Date.

            (42) With respect to any Mortgage Loan as to which an affidavit has
      been delivered to the Trustee certifying that the original Mortgage Note
      is a Lost Mortgage Note, if such Mortgage Loan is subsequently in default,
      the enforcement of such Mortgage Loan or of the related Mortgage by or on
      behalf of the Trustee will not be materially adversely affected by the
      absence of the original Mortgage Note. A "Lost Mortgage Note" is a
      Mortgage Note the original of which was permanently lost or destroyed and
      has not been replaced.

            (43) The Mortgage Loans, individually and in the aggregate, conform
      in all material respects to the descriptions thereof in the Prospectus
      Supplement.

insurance company which is purchasing such Certificates with funds contained in
an "insurance company general account" (as such term is defined in Section V(e)
of Prohibited Transaction Class Exemption 95-60 ("PTCE 95-60")) and that the
purchase and holding of such Certificates are covered under PTCE 95-60, or (iii)

employee benefit plan subject to ERISA or Section 4975 of the Code (or
comparable provisions of any subsequent enactments), or a trustee of any such
plan or any other person acting on behalf of any such plan, an Opinion of
Counsel satisfactory to the Trustee and the Master Servicer to the effect that
the purchase or holding of such 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 to
any obligation in addition to those undertaken in the Agreement, which Opinion
of Counsel shall not be an expense of the Trustee or the Master Servicer. [Such
representation shall be deemed to have been made to the Trustee by the
Transferee's acceptance of a Certificate of this Class and by a beneficial
owner's acceptance of its interest in a Certificate of this Class.]
Notwithstanding anything else to the contrary herein, any purported transfer of
a Certificate of this Class to or on behalf of an employee benefit plan subject
to ERISA or to the Code without the opinion of counsel satisfactory to the
Trustee as described above shall be void and of no effect.

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

called the "Certificates"), and representing a beneficial ownership interest in

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

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

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

            Distributions on this Certificate shall be made by wire transfer of
immediately available funds to the account of the Holder hereof at a bank or
other entity having appropriate facilities therefor, if such Certificateholder

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the

maintained by the Trustee in New York, New York, accompanied by a written
instrument of transfer in form satisfactory to the Trustee and the Certificate
Registrar duly executed by the holder hereof or such holder's attorney duly
authorized in writing, and thereupon one or more new Certificates of the same
Class in authorized denominations and evidencing the same aggregate Percentage
Interest in the Trust Fund will be issued to the designated transferee or
transferees.

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

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

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

            On any Distribution Date on which the Pool Stated Principal Balance
is less than 10% of the aggregate Cut-off Date Principal Balances of the
Mortgage Loans, the Master Servicer will have the option to repurchase, in
whole, from the Trust Fund all remaining Mortgage Loans and all property
acquired in respect of the Mortgage Loans at a purchase price determined as
provided in the Agreement. In the event that no such optional termination
occurs, the obligations and responsibilities created by the Agreement will
terminate upon the later of the maturity or other liquidation (or any advance
with respect thereto) of the last Mortgage Loan remaining in the Trust Fund or
the disposition of all property in respect thereof and the distribution to
Certificateholders of all amounts required to be distributed pursuant to the
Agreement. In no event, however, will the trust created by the Agreement
continue beyond the expiration of 21 years from the death of the last survivor
of the descendants living at the date of the Agreement of a certain person named
in the Agreement.

            Any term used herein that is defined in the Agreement shall have the
meaning assigned in the Agreement, and nothing herein shall be deemed
inconsistent with that meaning.

                        )  ss.:
COUNTY OF               )

            The undersigned, being first duly sworn, deposes and says as
follows:

            a. The undersigned is an officer of _____________, the proposed
Transferee of an Ownership Interest in a Class A-R Certificate (the
"Certificate") issued pursuant to the Pooling and Servicing Agreement, (the
"Agreement"), relating to the above-referenced Series, by and among Mellon
Residential Funding Corporation, as depositor (the "Depositor"),
________________, as seller and master servicer and Bankers Trust Company of
California, N.A.,, as Trustee. Capitalized terms used, but not defined herein or
in Exhibit 1 hereto, shall have the meanings ascribed to such terms in the
Agreement. The Transferee has authorized the undersigned to make this affidavit
on behalf of the Transferee.

            b. The Transferee is, as of the date hereof, and will be, as of the
date of the Transfer, a Permitted Transferee. The Transferee is acquiring its
Ownership Interest in the Certificate either (i) for its own account or (ii) as
nominee, trustee or agent for another Person and has attached hereto an
affidavit from such Person in substantially the same form as this affidavit. The
Transferee has no knowledge that any such affidavit is false.

            c. The Transferee has been advised of, and understands that (i) a
tax will be imposed on Transfers of the Certificate to Persons that are not
Permitted Transferees; (ii) such tax will be imposed on the transferor, or, if
such Transfer is through an agent (which includes a broker, nominee or
middleman) for a Person that is not a Permitted Transferee, on the agent; and
(iii) the Person otherwise liable for the tax shall be relieved of liability for
the tax if the subsequent Transferee furnished to such Person an affidavit that
such subsequent Transferee is a Permitted Transferee and, at the time of
Transfer, such Person does not have actual knowledge that the affidavit is
false.

            d. The Transferee has been advised of, and understands that a tax
will be imposed on a "pass-through entity" holding the Certificate if at any
time during the taxable year of the pass-through entity a Person that is not a
Permitted Transferee is the record holder of an interest in such entity. The
Transferee understands that such tax will not be imposed for any period with
respect to which the record holder furnishes to the pass-through entity an
affidavit that such record holder is a Permitted Transferee and the pass-through
entity does not have actual knowledge that such affidavit is false. (For this
purpose, a "pass-through entity" includes a regulated investment company, a real
estate investment trust or common trust fund, a partnership, trust or estate,
and certain cooperatives and, except as may be provided in Treasury Regulations,
persons holding interests in pass-through entities as a nominee for another
Person.)

<PAGE>   128

            e. The Transferee has reviewed the provisions of Section 5.02(c) of
the Agreement (attached hereto as Exhibit 2 and incorporated herein by
reference) and understands the legal consequences of the acquisition of an
Ownership Interest in the Certificate including, without limitation, the
restrictions on subsequent Transfers and the provisions regarding voiding the
Transfer and mandatory sales. The Transferee expressly agrees to be bound by and
to abide by the provisions of Section 5.02(c) of the Agreement and the
restrictions noted on the face of the Certificate. The Transferee understands
and agrees that any breach of any of the representations included herein shall
render the Transfer to the Transferee contemplated hereby null and void.

            f. The Transferee agrees to require a Transfer Affidavit from any
Person to whom the Transferee attempts to Transfer its Ownership Interest in the
Certificate, and in connection with any Transfer by a Person for whom the
Transferee is acting as nominee, trustee or agent, and the Transferee will not
Transfer its Ownership Interest or cause any Ownership Interest to be
Transferred to any Person that the Transferee knows is not a Permitted
Transferee. In connection with any such Transfer by the Transferee, the
Transferee agrees to deliver to the Trustee a certificate substantially in the
form set forth as Exhibit J to the Agreement (a "Transferor Certificate") to the
effect that such Transferee has no actual knowledge that the Person to which the
Transfer is to be made is not a Permitted Transferee.

            g. The Transferee does not have the intention to impede the
assessment or collection of any tax legally required to be paid with respect to
the Certificate.

            h. The Transferee's taxpayer identification number is .

            i. The Transferee is a U.S. Person as defined in Code Section
7701(a)(30).

            j. The Transferee is aware that the Certificate may be a
"noneconomic residual interest" within the meaning of proposed Treasury
regulations promulgated pursuant to the Code and that the transferor of a
noneconomic residual interest will remain liable for any taxes due with respect
to the income on such residual interest, unless no significant purpose of the
transfer was to impede the assessment or collection of tax.

            k. The Transferee is not an employee benefit plan that is subject to
ERISA or a plan that is subject to Section 4975 of the Code, and the Transferee
is not acting on behalf of such a plan.

                                                                    to EXHIBIT I

                               Certain Definitions

            "Ownership Interest": As to any Certificate, any ownership interest
in such Certificate, including any interest in such Certificate as the Holder
thereof and any other interest therein, whether direct or indirect, legal or
beneficial.

            "Permitted Transferee": Any Person other than (i) the United States,
any State or political subdivision thereof, or any agency or instrumentality of
any of the foregoing, (ii) a foreign government, International Organization or
any agency or instrumentality of either of the foregoing, (iii) an organization
(except certain farmers' cooperatives described in Code Section 521) which is
exempt from tax imposed by Chapter 1 of the Code (including the tax imposed by
Code Section 511 on unrelated business taxable income) on any excess inclusions
(as defined in Code Section 860E(c)(1)) with respect to any Class A-R
Certificate, (iv) rural electric and telephone cooperatives described in Code
Section 1381(a)(2)(c), (v) a Person that is not a citizen or resident of the
United States, a corporation, partnership, or other entity created or organized
in or under the laws of the United States or any political subdivision thereof,
or an estate or trust whose income from sources without the United States is
includible in gross income for United States federal income tax purposes
regardless of its connection with the conduct of a trade or business within the
United States, and (vi) any other Person so designated by the Trustee based upon
an Opinion of Counsel that the Transfer of an Ownership Interest in a Class A-R
Certificate to such Person may cause the Trust Fund to fail to qualify as a
REMIC at any time that certain Certificates are Outstanding. The terms "United
States," "State" and "International Organization" shall have the meanings set
forth in Code Section 7701 or successor provisions. A corporation will not be
treated as an instrumentality of the United States or of any State or political
subdivision thereof if all of its activities are subject to tax, and, with the
exception of the FHLMC, a majority of its board of directors is not selected by
such governmental unit.

            "Person": Any individual, corporation, partnership, joint venture,
bank, joint stock company, trust (including any beneficiary thereof),
unincorporated organization or government or any agency or political subdivision
thereof.

            "Transfer": Any direct or indirect transfer or sale of any Ownership
Interest in a Certificate, including the acquisition of a Certificate by the
Depositor.

            "Transferee": Any Person who is acquiring by Transfer any Ownership
Interest in a Certificate.

                                                                    to EXHIBIT I

                        Section 5.02(c) of the Agreement

            (a) Each Person who has or who acquires any Ownership Interest in a
Class A-R Certificate shall be deemed by the acceptance or acquisition of such
Ownership Interest to have agreed to be bound by the following provisions, and
the rights of each Person acquiring any Ownership Interest in a Class A-R
Certificate are expressly subject to the following provisions:

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

            (ii) No Ownership Interest in a Class A-R Certificate may be
      registered on the Closing Date or thereafter transferred, and the Trustee
      shall not register the Transfer of any Class A-R Certificate unless, in
      addition to the certificates required to be delivered to the Trustee under
      subparagraph (b) above, the Trustee shall have been furnished with an
      affidavit (a "Transfer Affidavit") of the initial owner or the proposed
      transferee in the form attached hereto as Exhibit I.

            (iii) Each Person holding or acquiring any Ownership Interest in a
      Class A-R Certificate shall agree (A) to obtain a Transfer Affidavit from
      any other Person to whom such Person attempts to Transfer its Ownership
      Interest in a Class A-R Certificate, (B) to obtain a Transfer Affidavit
      from any Person for whom such Person is acting as nominee, trustee or
      agent in connection with any Transfer of a Class A-R Certificate and (C)
      not to Transfer its Ownership Interest in a Class A-R Certificate or to
      cause the Transfer of an Ownership Interest in a Class A-R Certificate to
      any other Person if it has actual knowledge that such Person is not a
      Permitted Transferee.

            (iv) Any attempted or purported Transfer of any Ownership Interest
      in a Class A-R Certificate in violation of the provisions of this Section
      5.02(c) shall be absolutely null and void and shall vest no rights in the
      purported Transferee. If any purported transferee shall become a Holder of
      a Class A-R Certificate in violation of the provisions of this Section
      5.02(c), then the last preceding Permitted Transferee shall be restored to
      all rights as Holder thereof retroactive to the date of registration of
      Transfer of such Class A-R Certificate. The Trustee shall be under no
      liability to any Person for any registration of Transfer of a Class A-R
      Certificate that is in fact not permitted by Section 5.02(b) and this
      Section 5.02(c) 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 after receipt of the related Transfer Affidavit, Transferor
      Certificate and either the Rule 144A Letter or the Investment Letter. The
      Trustee shall be entitled but not obligated to recover from any Holder of
      a Class A-R Certificate that was in fact not a Permitted Transferee at the
      time it became a Holder or, at such subsequent time as it became other
      than a Permitted Transferee, all payments made on such Class A-R
      Certificate at and after either such time. Any such payments so recovered
      by the Trustee shall be paid and delivered by the Trustee to the last
      preceding Permitted Transferee of such Certificate.

            (v) The Depositor shall use its best efforts to make available, upon
      receipt of written request from the Trustee, all information necessary to
      compute any tax imposed under Section 860E(e) of the Code as a result of a
      Transfer of an Ownership Interest in a Class A-R Certificate to any Holder
      who is not a Permitted Transferee.
