Ladies and Gentlemen:

        First Union Residential Securitization Transactions, Inc. (the
"Depositor"), a North Carolina corporation, is a wholly-owned, special-purpose
subsidiary of First Union National Bank of North Carolina ("FUNB"), a national
banking association. The Depositor has authorized the issuance and sale of its
Mortgage Pass-Through Certificates, Series 1998-A, consisting of (i) Class SA-1,
Class SA-2, Class SA-3, Class SA-4, Class SA-5 and Class SA-X (the "Class SA
Certificates"), (ii) Class A-1, Class A-2, Class A-3, Class A-4, Class A-5,
Class A-6, Class A-7 and Class A-X (the "Class A Certificates"), (iii) Class M,
Class B-1 and Class B-2 (the "Senior Subordinate Certificates"), (iv) Class R-I
and R-II (the "Residual Certificates" and, together with the Class SA
Certificates, the Class A Certificates and the Senior Subordinate Certificates,
the "Offered Certificates"), and (v) Class B-3, Class B-4 and Class B-5 (the
"Junior Subordinate Certificates" and, together with the Offered Certificates,
the "Certificates"). Each Class of the Certificates evidences interests in a
pool (the "Trust Fund") of fixed-rate mortgage loans (the "Mortgage Loans"),
secured by first deeds of trust and mortgages on one- to four-family residential
properties.

         Only the Offered Certificates are being purchased by First Union
Capital Markets, a division of Wheat First Securities, Inc. ("FUCM") and
Donaldson, Lufkin & Jenrette Securities 


                                       1
<PAGE>   3


Corporation ("DLJ" and, together with FUCM, the "Underwriters"), severally, in
the amount set forth opposite their names on Schedule A, except that the amount
purchased by each Underwriter may change in accordance with Section 10 of this
Agreement.

         The Certificates will be issued under a pooling and servicing agreement
(the "Pooling and Servicing Agreement"), dated as of April 1, 1998, among the
Depositor, FUNB, as seller (the "Seller"), First Union Mortgage Corporation as
servicer (the "Servicer"), and Norwest Bank Minnesota, National Association, as
trustee and document custodian (the "Trustee"). The Certificates will evidence
fractional undivided interests in the Trust Fund. The assets of the Trust Fund
will include, among other things, the Mortgage Loans conveyed to the Trust Fund
on April 29, 1998, and such amounts as may be held by the Trustee in any
accounts held by the Trustee for Trust Fund including a pre-funding amount. The
aggregate undivided interest in the Trust Fund represented by the Offered
Certificates initially will be equal to $347,077,774 of principal, which
represents 99.15% of the actual principal balances of the Mortgage Loans as of
April 1, 1998 (thc "Cut-Off Date") and amounts in the pre-funding account. Forms
of the Pooling and Servicing Agreement have been filed as exhibits to the
Registration Statement (hereinafter defined).

         One or more elections will be made to treat certain segregated pools of
assets of the Trust Fund as "real estate mortgage investment conduits" (each, a
"REMIC") for federal income tax purposes. The Certificates (other than the Class
R Certificates) will constitute "regular interests" in a REMIC, and each
component of the Class R Certificates will constitute "residual interests" in a
REMIC.

         The Offered Certificates are more fully described in the Registration
Statement (defined below) which the Depositor has furnished to the Underwriters.
Capitalized terms used but not defined herein shall have the meanings given to
them in the Pooling and Servicing Agreement.

         Simultaneously with the execution of the Pooling and Servicing
Agreement, the Depositor will enter into a mortgage loan purchase agreement (the
"Purchase Agreement") with the Seller, pursuant to which the Seller will
transfer to the Depositor all of its right, title and interest in and to the
Mortgage Loans as of the Cut-Off Date and the collateral securing each Mortgage
Loan.

         SECTION 1.        REPRESENTATIONS AND WARRANTIES OF THE DEPOSITOR

         The Depositor represents and warrants to, and agrees with the
Underwriters that:

         (a) A Registration Statement on Form S-3 (No. 333-3574), as amended,
has (i) been prepared by the Depositor in conformity with the requirements of
the Securities Act of 1933, as amended (the "Securities Act"), and the rules and
regulations (the "Rules and Regulations") of the United States Securities and
Exchange Commission (the "Commission") thereunder, (ii) been filed with the
Commission under the Securities Act and (iii) as amended by Pre-Effective
Amendment No. 2 thereto, become effective under the Securities Act. Copies of
such Registration Statement have been delivered by the Depositor to the
Underwriters. As used in this Agreement, "Effective Time" means the date and the
time as of which such Registration 


                                       2
<PAGE>   4


Statement, or the most recent post-effective amendment thereto, if any, was
declared effective by the Commission; "Effective Date" means the date of the
Effective Time; "Registration Statement" means such registration statement at
the Effective Time, including any documents incorporated by reference therein at
such time; and "Prospectus" means the final prospectus, dated April 24, 1998, as
first supplemented by a prospectus supplement, dated April 24, 1998 (the
"Prospectus Supplement"), relating to the Offered Certificates, as first filed
with the Commission pursuant to Rule 424(b) of the Rules and Regulations.
Reference made herein to the Prospectus shall be deemed to refer to and include
any documents incorporated by reference therein pursuant to Item 12 of Form S-3
under the Securities Act, as of the date of the Prospectus and any reference to
any amendment or supplement to the Prospectus shall be deemed to refer to and
include any document filed under the Securities Exchange Act of 1934, as amended
(the "Exchange Act"), after the date of the Prospectus and incorporated by
reference in the Prospectus; and any reference to any amendment to the
Registration Statement shall be deemed to include any report of the Depositor
filed with the Commission pursuant to Section 13(a) or 15(d) of the Exchange Act
after the Effective Time that is incorporated by reference in the Registration
Statement. The Commission has not issued, and the Depositor has not received any
notification that the Commission intends to issue any order preventing or
suspending the use of the Registration Statement. There are no contracts or
documents of the Depositor which are required to be filed as exhibits to the
Registration Statement pursuant to the Securities Act or the Rules and
Regulations which have not been so filed or incorporated by reference therein on
or prior to the Closing Date (defined below). The conditions for use of Form
S-3, as set forth in the General Instructions thereto, have been satisfied.

         To the extent that any Underwriter (A) has provided to the Depositor
Collateral Term Sheets (defined below) that such Underwriter has provided to a
prospective investor, the Depositor has filed such Collateral Term Sheets as an
exhibit to a report on Form 8-K within two business days of its receipt thereof,
or (B) has provided to the Depositor Structural Term Sheets or Computational
Materials (each as defined below) that such Underwriter has provided to a
prospective investor, the Depositor will file or cause to be filed with the
Commission a report on Form 8-K containing such Structural Term Sheets and
Computational Material as soon as reasonably practicable after the date of this
Agreement, but in any event not later than the date on which the Prospectus is
filed with the Commission pursuant to Rule 424 of the Rules and Regulations.

         (b) The Registration Statement conforms, and the Prospectus and any
further amendments or supplements to the Registration Statement or the
Prospectus will, when they become effective or are filed with the Commission, as
the case may be, conform in all respects to the requirements of the Securities
Act and the Rules and Regulations. The Registration Statement, as of the
Effective Date thereof and of any amendment thereto, did not contain an untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein not misleading. The
Prospectus as of its date, and as amended or supplemented as of the Closing Date
does not and will not contain any untrue statement of a material fact or omit to
state a material fact necessary in order to make the statements therein, in the
light of the circumstances under which they were made, not misleading; provided
that no representation or warranty is made as to information contained in or
omitted 


                                       3
<PAGE>   5


from the Registration Statement or the Prospectus in reliance upon and in
conformity with written information furnished to the Depositor in writing by the
Underwriters expressly for use therein. The parties hereto acknowledge that the
only information provided by the Underwriters is that information described in
Section 8(h).

         (c) The documents incorporated by reference in the Prospectus, when
they became effective or were filed with the Commission, as the case may be,
conformed in all material respects to the requirements of the Securities Act or
the Exchange Act, as applicable, and the rules and regulations of the Commission
thereunder, and none of such documents contained an untrue statement of a
material fact or omitted to state a material fact required to be stated therein
or necessary to make the statements therein not misleading; and any further
documents so filed and incorporated by reference in the Prospectus, when such
documents become effective or are filed with the Commission, as the case may be,
will conform in all material respects to the requirements of the Securities Act
or the Exchange Act, as applicable, and the rules and regulations of the
Commission thereunder, and will not contain an untrue statement of a material
fact or omit to state a material fact necessary in order to make the statements
therein, in the light of the circumstances under which they were made, not
misleading.

         (d) Since the respective dates as of which information is given in the
Prospectus, there has not been any material adverse change in the general
affairs, management, financial condition, or results of operations of the
Depositor, otherwise than as set forth or contemplated in the Prospectus as
supplemented or amended as of the Closing Date.

         (e) The Depositor has been duly incorporated and is validly existing as
a corporation in good standing under the laws of its jurisdiction of
incorporation, is duly qualified to do business and is in good standing as a
foreign corporation in each jurisdiction in which its ownership or lease of
property or the conduct of its business requires such qualification, and has all
power and authority necessary to own or hold its properties, to conduct the
business in which it is engaged and to enter into and perform its obligations
under this Agreement, the Pooling and Servicing Agreement and the Purchase
Agreement, and to cause the Certificates to be issued.

         (f) There are no actions, proceedings or investigations pending before
or, to the knowledge of the Depositor, threatened by any court, administrative
agency or other tribunal to which the Depositor is a party or of which any of
its properties is the subject (i) which if determined adversely to the Depositor
would have a material adverse effect on the business or financial condition of
the Depositor, (ii) asserting the invalidity of this Agreement, the Pooling and
Servicing Agreement, the Purchase Agreement or the Certificates, (iii) seeking
to prevent the issuance of the Certificates or the consummation by the Depositor
of any of the transactions contemplated by the Pooling and Servicing Agreement,
the Purchase Agreement or this Agreement, as the case may be, or (iv) which
might materially and adversely affect the performance by the Depositor of its
obligations under, or the validity or enforceability of, the Pooling and
Servicing Agreement, the Purchase Agreement, this Agreement or the Certificates.

         (g) This Agreement has been, and the Pooling and Servicing Agreement
and the Purchase Agreement when executed and delivered as contemplated hereby
and thereby will have 


                                       4

been, duly authorized, executed and delivered by the Depositor, and this
Agreement constitutes, and the Pooling and Servicing Agreement and the Purchase
Agreement, when executed and delivered as contemplated herein, will constitute,
legal valid and binding instruments enforceable against the Depositor in
accordance with their respective terms, subject as to enforceability to (i)
applicable bankruptcy, reorganization, insolvency, moratorium or other similar
laws affecting creditors' rights generally, (ii) general principles of equity
(regardless of whether enforcement is sought in a proceeding in equity or at
law), and (iii) with respect to rights of indemnity under this Agreement and the
Purchase Agreement, limitations of public policy under applicable securities
laws.

         (h) The execution, delivery and performance of this Agreement, the
Pooling and Servicing Agreement and the Purchase Agreement by the Depositor and
the consummation of the transactions contemplated hereby and thereby, and the
issuance and delivery of the Certificates do not and will not conflict with or
result in a breach or violation of any of the terms or provisions of, or
constitute a default under, any indenture, mortgage, deed of trust, loan
agreement or other agreement or instrument to which the Depositor is a party, by
which the Depositor is bound or to which any of the property or assets of the
Depositor or any of its subsidiaries is subject, nor will such actions result in
any violation of the provisions of the articles of incorporation or bylaws of
the Depositor or any statute or any order, rule or regulation of any court or
governmental agency or body having jurisdiction over the Depositor or any of its
properties or assets.

         (i) Deloitte & Touche LLP are independent public accountants with
respect to the Depositor as required by the Securities Act and the Rules and
Regulations.

         (j) The direction by the Depositor to the Trustee to execute,
authenticate, issue and deliver the Certificates has been duly authorized by the
Depositor, and assuming the Trustee has been duly authorized to do so, when
executed, authenticated, issued and delivered by the Trustee in accordance with
the Pooling and Servicing Agreement, the Certificates will be validly issued and
outstanding and will be entitled to the benefits provided by the Pooling and
Servicing Agreement.

         (k) No consent, approval, authorization, order, registration or
qualification of or with any court or governmental agency or body of the United
States is required for the issuance of the Certificates and the sale of the

         material fact required to be stated therein or necessary to make the
         statements therein not misleading, and (B) since the Effective Date no

for the purpose of enabling them to pass upon the issuance and sale of the
Certificates as herein contemplated and related proceedings or in order to

contemplated shall be satisfactory in form and substance to the Underwriters and
counsel for the Underwriters.

         (p) Subsequent to the execution and delivery of this Agreement none of
the following shall have occurred: (i) trading in securities generally on the

such) as to make it, in the judgment of the Underwriters, impractical or
inadvisable to proceed with the public offering or delivery of the Certificates
on the terms and in the manner contemplated in the Prospectus.

         If any condition specified in this Section 6 shall not have been

Closing Date, and such termination shall be without liability of any party to
any other party except as provided in Section 7.

         SECTION 8.        INDEMNIFICATION AND CONTRIBUTION

         (a) (i)  The Depositor and FUNB agree to indemnify and hold harmless 
         the Underwriters, their directors and each person, if any, who controls
         the Underwriters within the meaning of Section 15 of the Securities Act
         from and against any and all loss, claim, damage or liability, joint or
         several, or any action in respect thereof (including, but not limited
         to, any loss, claim damage, liability or action relating to purchases
         and sales of the Offered Certificates), to which the Underwriters,
         their directors or any such controlling person may become subject,
         under the Securities Act or otherwise, insofar as such loss, claim,
         damage, liability or action arises out of, or is based upon, (A) any
         untrue statement or alleged untrue statement of a material fact
         contained in the Registration Statement, (B) the omission or alleged
         omission to state therein a material fact required to be stated therein
         or necessary to make the statements therein not misleading, (C) any
         untrue statement or alleged untrue statement of a material fact
         contained in the Prospectus or (D) the omission or alleged omission to
         state, in the Prospectus, a material fact required to be stated therein
         or necessary to make the statements in the Prospectus, in the light of
         the circumstances under which they were made, not misleading and shall
         reimburse each Underwriter, each such director and each such
         controlling person promptly upon demand for any legal or other expenses
         reasonably incurred by such Underwriter, such director or such
         controlling person in connection with investigating or defending or
         preparing to defend against any such loss, claim, damage, liability or
         action, as such expenses are incurred; provided, however, that the
         Depositor and FUNB shall not be liable in any such case to the extent
         that any such loss, claim, damage, liability or action arises out of,
         or is based upon, any untrue statement or alleged untrue statement or
         omission or alleged omission made in the Prospectus or the Registration
         Statement in reliance upon and in conformity with written information
         furnished to the Depositor by or on behalf of any of the Underwriters
         specifically for inclusion therein (as specified in Section 8(h)
         below). The foregoing indemnity agreement is in addition to any
         liability which the Depositor and FUNB may otherwise have to the
         Underwriters, its directors or any controlling person of the
         Underwriters.

             (ii) The Depositor and FUNB agree to indemnify and hold harmless
         DLJ, its directors and each person, if any, who controls DLJ within the
         meaning of Section 15 of the Securities Act from and against any and
         all loss, claim, damage or liability, joint or several, or any action
         in respect thereof (including, but not limited to, any loss, claim,
         damage, liability or action relating to purchases and sales of the
         Offered Certificates), to which DLJ, its directors or any such
         controlling person may become subject, under the Securities Act or
         otherwise, insofar as such loss, claim, damage, liability or action
         arises out of, or is based upon, (A) any untrue statement or alleged
         untrue statement of a material fact contained in any prospectus used
         after July 28, 1998 (a "Market Making Prospectus"), or (B) the omission
         or alleged omission to state therein a material fact required to be
         stated therein or necessary to make the statements therein, in the
         light of the circumstances under which they were made, not misleading,
         and shall reimburse DLJ, each such director and each such controlling
         person promptly upon demand for any legal or other expenses reasonably
         incurred by DLJ, such director or such controlling person in connection
         with investigating or defending or preparing to defend against any such
         loss, 


                                       18
<PAGE>   20


         claim, damage, liability or action, as such expenses are incurred;
         provided, however, the Depositor and FUNB shall not be liable in any
         such case to the extent that any such loss, claim, damage, liability or
         action arises out of, or is based upon, any untrue statement or alleged
         untrue statement or omission or alleged omission made in a Market
         Making Prospectus in reliance upon and in conformity with written
         information furnished to the Depositor by DLJ specifically for
         inclusion therein (as specified in Section 8(h) below). The foregoing
         indemnity agreement is in addition to any liability which the Depositor
         and FUNB may otherwise have to DLJ, its directors or any controlling
         person of DLJ under this Agreement.

         (b) (i)  Each Underwriter severally agrees to indemnify and hold
         harmless the Depositor, each of its directors, each of its officers who
         signed the Registration Statement, and each person, if any, who
         controls the Depositor within the meaning of Section 15 of the
         Securities Act against any and all loss, claim, damage or liability, or
         any action in respect thereof, to which the Depositor or any such
         director, officer or controlling person may become subject, under the
         Securities Act or otherwise, insofar as such loss, claim, damage,
         liability or action arises out of, or is based upon, (i) an untrue,
         statement or alleged untrue statement of a material fact contained in
         the Registration Statement, (ii) the omission or alleged omission to
         state therein a material fact required to be stated therein or
         necessary to make the statements therein not misleading, (iii) any
         untrue statement or alleged untrue statement of a material fact
         contained in the Prospectus or (iv) the omission or alleged omission to
         state therein a material fact required to be stated in the Prospectus
         or necessary to make the statements in the Prospectus, in the light of
         the circumstances under which they were made, not misleading, but in
         each case only to the extent that the untrue statement or alleged
         untrue statement or omission or alleged omission was made in reliance
         upon and in conformity with written information furnished to the
         Depositor by or on behalf of the Underwriters specifically for
         inclusion therein (as specified in Section 8(h) below), and shall
         reimburse the Depositor and any such director, officer or controlling
         person for any legal or other expenses reasonably incurred by the
         Depositor or any director, officer or controlling person in connection
         with investigating or defending or preparing to defend against any such
         loss, claim, damage, liability or action as such expenses are incurred.
         The foregoing indemnity agreement is in addition to any liability which
         the Underwriters may otherwise have to the Depositor or any such
         director, officer or controlling person. Notwithstanding anything to
         the contrary contained in this Section 8, DLJ shall have no obligation
         to indemnify any party for any loss, claim, damage or liability or
         contribute to any such loss, claim, damage or liability in respect of
         untrue Statements or alleged untrue statements of material fact or
         omissions or alleged omissions to state a material fact contained in
         any Market Making Prospectus.

             (ii) DLJ shall indemnify and hold harmless FUCM and each person, if
         any, who controls FUCM within the meaning of Section 15 of the
         Securities Act from and against any loss, claim, damage or liability,
         joint or several, and any action in respect thereof, to which FUCM or
         any such controlling person may become subject, under the Securities
         Act or otherwise, insofar as such loss, claim, damage, liability or
         action arises 


                                       19
<PAGE>   21


         out of, or is based upon, any untrue statement or alleged untrue
         statement of a material fact contained in any Computational Materials
         (defined below) furnished or made available by DLJ to offerees of the
         Offered Certificates.

                  FUCM shall indemnify and hold harmless DLJ and each person, if
         any, who controls DLJ within the meaning of Section 15 of the
         Securities Act from and against any loss, claim, damage or liability,
         joint or several, and any action in respect thereof, to which DLJ or
         any such controlling person may become subject, under the Securities
         Act or otherwise, insofar as such loss, claim, damage, liability or
         action arises out of, or is based upon, any untrue statement or alleged
         untrue statement of a material fact contained in any Computational
         Materials furnished or made available by FUCM to offerees of the
         Offered Certificates.

         (c) Promptly after receipt by any indemnified party under this Section
8 of notice of any claim or the commencement of any action, such indemnified
party shall, if a claim in respect thereof is to be made against any
indemnifying party under this Section 8, notify the indemnifying party in
writing of the claim or the commencement of that action; provided, however, that
the failure to notify an indemnifying party shall not relieve it from any
liability which it may have under this Section 8 except to the extent it has
been materially prejudiced by such failure; and, provided further, that the
failure to notify any indemnifying party shall not relieve it from any liability
which it may have to any indemnified party otherwise than under this Section 8.

         If any such claim or action shall be brought against an indemnified
party, and it shall notify the indemnifying party thereof, the indemnifying
party shall be entitled to participate therein and, to the extent that it
wishes, jointly with any other similarly notified indemnifying party, to assume
the defense thereof with counsel reasonably satisfactory to the indemnified
party. After notice from the indemnifying party to the indemnified party of its
election to assume the defense of such claim or action, the indemnifying party
shall not be liable to the indemnified party under this Section 8 for any legal
or other expenses subsequently incurred by the indemnified party in connection
with the defense thereof other than reasonable costs of investigation.

         Any indemnified party shall have the right to employ separate counsel
in any such action and to participate in the defense thereof, but the fees and
expenses of such counsel shall be at the expense of such indemnified party
unless: (i) the employment thereof has been specifically authorized by the
indemnifying party in writing; (ii) such indemnified party shall have been
advised by such counsel that there may be one or more legal defenses available
to it which are different from or additional to those available to the
indemnifying party and in the reasonable judgment of such counsel it is
advisable for such indemnified party to employ separate counsel; or (iii) the
indemnifying party has failed to assume the defense of such action and employ
counsel reasonably satisfactory to the indemnified party, in which case, if such
indemnified party notifies the indemnifying party in writing that it elects to
employ separate counsel at the expense of the indemnifying party, the
indemnifying party shall not have the right to assume the defense of such action
on behalf of such indemnified party, it being understood, however, the


                                       20
<PAGE>   22


indemnifying party shall not, in connection with any one such action or separate
but substantially similar or related actions in the same jurisdiction arising
out of the same general allegations or circumstances, be liable for the
reasonable fees and expenses of more than one separate firm of attorneys (in
addition to local counsel) at any time for all such indemnified parties, which
firm shall be designated in writing by the Underwriters, if the indemnified
parties under this Section 8 consist of the Underwriters or any of their
directors and controlling persons, or by the Depositor, if the indemnified
parties under this Section 8 consist of the Depositor or any of the Depositor's
directors, officers or controlling persons.

         Each indemnified party, as a condition of the indemnity agreements
contained in Section 8(a) and (b), shall use its best efforts to cooperate with
the indemnifying parry in the defense of any such action or claim. No
indemnifying party shall be liable for any settlement of any such action
effected without its written consent (which consent shall not be unreasonably
withheld), but if settled with its written consent or if there be a final
judgment for the plaintiff in any such action, the indemnifying party agrees to
indemnify and hold harmless any indemnified party from and against any loss or
liability by reason of such settlement or judgment.

         Notwithstanding the foregoing sentence, if at any time an indemnified
party shall have requested an indemnifying party to reimburse the indemnified
party for fees and expenses of counsel, the indemnifying party agrees that it
shall be liable for any settlement of any proceeding effected, without its
written consent if (A) such settlement is entered into more than 30 days after
receipt by such indemnifying party of the aforesaid request and (B) such
indemnifying party shall not have reimbursed the indemnified party in accordance
with such request prior to the date of such settlement.

         (d) (i)  Each Underwriter agrees to provide the Depositor no later than
         two Business Days prior to the day on which the Prospectus Supplement
         is required to be filed pursuant to Rule 424 with a copy of its
         Structural Term Sheets and Computational Materials (each as defined
         below), if any, for filing with the Commission an Form 8-K.

             (ii) Each Underwriter agrees to provide the Depositor with its
         Collateral Term Sheets no later than one Business Day prior to the day
         on which such Collateral Term Sheets are distributed to potential
         investors.

         (e) Each Underwriter agrees, severally and not jointly, assuming all
Seller-Provided Information (defined below) is accurate and complete in all
material respects, to indemnify and hold harmless the Depositor, each of the
Depositor's officers who sign the Registration Statement and directors and each
person who controls the Depositor within the meaning of Section 15 of the
Securities Act against any and all losses, claims, damages or liabilities, joint
or several, to which they may become subject under the Securities Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon any untrue statement of a
material fact contained in the Derived Information (defined below) provided by
such Underwriter, or arise out of or are based upon the omission or alleged
omission, when read in conjunction with the Prospectus, to state therein a
material fact required to be stated therein or necessary to make the statements
therein, in the light of the circumstances 


                                       21
<PAGE>   23


under which they were made, not misleading, and agrees to reimburse each such
indemnified party for any legal or other expenses reasonably incurred by him,
her or it in connection with investigating or defending or preparing to defend
any such loss, claim, damage, liability or action as such expenses are incurred.
The obligations of an Underwriter under this Section 8(e) shall be in addition
to any liability which such Underwriter may otherwise have.

         The procedures set forth in Section 8(c) shall be equally applicable to
this Section 8(e).

         (f) If the indemnification provided for in this Section 8 shall for any
reason be unavailable to or insufficient to hold harmless an indemnified party
under Section 8(a), (b) or (e) in respect of any loss, claim, damage or
liability, or any action in respect thereof, referred to therein, then each
indemnifying party shall, in lieu of indemnifying such indemnified party,
contribute to the amount paid or payable by such indemnified party as a result
of such loss, claim, damage or liability, or action in respect thereof, (i) in
such proportion as shall be appropriate to reflect the relative benefits
received by the Depositor on the one hand and the Underwriters on the other from
the offering of the Certificates or (ii) if the allocation provided by clause
(i) above is not permitted by applicable law or if the indemnified party failed
to give the notice required under Section 8(c), in such proportion as is
appropriate to reflect not only the relative benefits referred to in clause (i)
above but also the relative fault of the Depositor on the one hand and the
Underwriters on the other with respect to the statements or omissions which
resulted in such loss, claim, damage or liability, or action in respect thereof,
as well as any other relevant equitable considerations.

         The relative benefits of the Underwriters and the Depositor shall be
deemed to be in such proportions that the Underwriters are responsible for their
pro rata portion of such losses, liabilities, claims, damages and expenses
determined in accordance with the ratio that the difference between the purchase
price paid to the Depositor by the Underwriters and the aggregate resale price
received by the Underwriters bears to the purchase price paid to the Depositor
by the Underwriters, and the Depositor shall be responsible for the balance.

         The relative fault of the Underwriters and the Depositor shall be
determined by reference to whether the untrue or alleged untrue statement of a
material fact or omission or alleged omission to state a material fact relates
to information supplied by the Depositor or by the Underwriters, the intent of
the parties and their relative knowledge, access to information and opportunity
to correct or prevent such statement or omission and other equitable
considerations.

         The Depositor and the Underwriters agree that it would not be just and
equitable if contributions pursuant to this Section 8(f) were to be determined
by pro rata allocation or by any other method of allocation which does not take
into account the equitable considerations referred to herein. The amount paid or
payable by an indemnified party as a result of the loss, claim, damage or
liability, or action in respect thereof, referred to above in this Section 8(f),
shall be deemed to include, for purposes of this Section 8(f), any legal or
other expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim.

         In no case shall the Underwriters be responsible for any amount in
excess of the difference between the purchase price paid to the Depositor by the
Underwriters and the aggregate resale price received by the Underwriters. No
person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.

         (g) For purposes of this Section 8, the term "Derived Information"
means such portion, if any, of the information delivered to the Depositor
pursuant to Section 8(d) for filing with the Commission on Form 8-K as:

             (i)   is not contained in the Prospectus without taking into 
         account information incorporated therein by reference;

             (ii)  does not constitute Seller-Provided Information; and

             (iii) is of the type of information defined as Collateral Term
         Sheets, Structural Term Sheets or Computational Materials (as such term
         are interpreted in the No-Action Letters (defined below)).

"Seller-Provided Information" means the information contained on any computer
tape furnished to the Underwriters by FUNB concerning the assets comprising the
Trust Fund.

         The terms "Collateral Term Sheet" and "Structural Term Sheet" shall
have the respective meanings assigned to them in the February 13, 1995, letter
(the "PSA Letter") of Cleary, Gottlieb, Steen & Hamilton on behalf of the Public
Securities Association (which letter, and the Commission staff's response
thereto, were publicly available February 17, 1995). The term "Collateral Term
Sheet," as used herein, includes any subsequent Collateral Term Sheet that
reflects a substantive change in the information presented. The term
"Computational Materials" has the meaning assigned to it in the May 17, 1994,
letter (the "Kidder Letter" and, together with the PSA Letter, the "No-Action
Letters") of Brown & Wood an behalf of Kidder, Peabody & Co., Inc. (which
letter, and the SEC staffs response thereto, were publicly available May 20,
1994).

         DLJ shall cooperate with the Depositor and with Deloitte & Touche LLP
in obtaining a letter, in form and substance satisfactory to the Depositor and
DLJ, of Deloitte & Touche LLP regarding the information in any Form 8-K
consisting of Computational Materials and/or Structural Term Sheets furnished by
DLJ, in each case in EDGAR format as formatted by the Depositor. Any such letter
shall be obtained prior to the filing of any such Form 8-K with the Commission
at DLJ's sole expense.

         DLJ represents warrants to, and covenants with, the Depositor that the
Derived Information is not misleading and not inaccurate in any material respect
and that any Seller-Provided Information contained in any Form 8-K which is not
otherwise inaccurate in any material respect is not presented in the Form 8-K in
a way that is either misleading or inaccurate in any material respect. DLJ
further covenants with the Depositor that if any Computational 


                                       23
<PAGE>   25


Materials or Collateral Term Sheets contained in any Form 8-K are found to
include any information that is misleading or inaccurate in any material
respect, DLJ promptly shall inform the Depositor of such finding, provide the
Depositor with revised and/or corrected Computational Materials or Collateral
Term Sheets, as the case may be, and promptly prepare and deliver to the
Depositor (in hard copy and EDGAR format) for filing with the Commission in
accordance herewith, revised and/or corrected Computational Materials or
Collateral Term Sheets, as the case may be.

         DLJ covenants that all Computational Materials and Collateral Term
Sheets used by it shall contain the following legend:

         "THIS INFORMATION IS FURNISHED TO YOU SOLELY BY DLJ AND NOT BY THE
         ISSUER OR ANY OF ITS AFFILIATES. NEITHER THE ISSUER NOR ANY OF ITS
         AFFILIATES MAKES ANY REPRESENTATION AS TO THE ACCURACY OR COMPLETENESS
         OF THE INFORMATION HEREIN. THE INFORMATION HEREIN IS PRELIMINARY, AND
         WILL BE SUPERSEDED BY THE APPLICABLE PROSPECTUS SUPPLEMENT AND BY ANY
         OTHER INFORMATION SUBSEQUENTLY FILED WITH THE SECURITIES AND EXCHANGE
         COMMISSION.

         DLJ covenants that all Collateral Term Sheets used by it shall contain
the following additional legend:

         "THIS INFORMATION CONTAINED HEREIN SUPERSEDED BY THE DESCRIPTION OF THE
         MORTGAGE LOANS CONTAINED IN THE PROSPECTUS SUPPLEMENT."

         DLJ covenants that all Collateral Term Sheets (other than the initial
Collateral Term Sheet) shall contain the following additional legend:

         "THIS INFORMATION CONTAINED HEREIN SUPERSEDES THE INFORMATION IN ALL
         PRIOR COLLATERAL TERM SHEETS, IF ANY."

         If the Underwriters do not provide any Computation Materials or
Collateral Term Sheets to the Depositor pursuant to the preceding paragraphs,
the Underwriters shall be deemed to have represented, as of the Closing Date,
that they did not provide any prospective investors with any information in
written or electronic form in connection with the offering of the Certificates
that is required to be filed with the Commission in accordance with the
No-Action Letters, and the Underwriters shall provide the Depositor with a
certification to that effect on the Closing Date.

         (h) The Underwriters confirm that the information set forth (i) in the
paragraph preceding the penultimate paragraph on the cover page, (ii) under the
caption "Summary of Terms of the Offered Certificates--Denominations" in the
Prospectus Supplement and (iii) in the first paragraph and the first sentence of
the third paragraph under the caption "Underwriting" in the Prospectus
Supplement is correct and, except for the additional information noted in the


                                       24
<PAGE>   26


following sentence, constitutes the only information furnished in writing to the
Depositor by or on behalf of the Underwriters specifically for inclusion in the
Registration Statement and the Prospectus. In addition, FUCM confirms that the
information set forth in the penultimate paragraph on the cover page is correct
and has been furnished in writing to the Depositor by FUCM specifically for
inclusion in the Registration Statement and the Prospectus.

         SECTION 9.        REPRESENTATIONS, WARRANTIES AND AGREEMENTS TO SURVIVE
DELIVERY

         All representations, warranties and agreements contained in this
Agreement or contained in certificates of officers of the Depositor submitted
pursuant hereto shall remain operative and in full force and effect, regardless
of any investigation made by or on behalf of the Underwriters or controlling
persons thereof, or by or an behalf of the Depositor and shall survive delivery
of any Certificates to the Underwriters.

         SECTION 10.       DEFAULT BY ONE OF THE UNDERWRITERS

         If one of the Underwriters participating in the public offering of the
Offered Certificates shall fail at the Closing Date to purchase the Offered
Certificates which it is obligated to purchase hereunder (the "Defaulted
Certificates"), then the non-defaulting Underwriter shall have the right, within
24 hours thereafter, to purchase all, but not less than all, of the Defaulted
Certificates in such amounts as may be agreed upon and upon the terms herein set
forth. If, however, the non-defaulting Underwriter has not completed such
arrangements within such 24-hour period, then:

                  (a) if the aggregate principal amount of Defaulted
         Certificates does not exceed 10% of the aggregate principal amount of
         the Offered Certificates to be purchased pursuant to this Agreement,
         the non-defaulting Underwriter shall be obligated to purchase the full
         amount thereof, or

                  (b) if the aggregate principal amount of Defaulted
         Certificates exceeds 10% of the aggregate principal amount of the
         Offered Certificates to be purchased pursuant to this Agreement, this
         Agreement shall terminate, without any liability an the part of the
         non-defaulting Underwriter.

         No action taken pursuant to this Section 10 shall relieve a defaulting
Underwriter from the liability with respect to any default of such Underwriter
under this Agreement.

         In the event of a default by any Underwriter as set forth in this
Section 10, the non-defaulting Underwriter and the Depositor shall have the
right to postpone the Closing Date for a period not exceeding five Business Days
in order that any required changes in the Registration Statement or Prospectus
or in any other documents or arrangements may be effected.

                  (i)   the original Mortgage Note, endorsed "Pay to the order

         registered holders from time to time of FURST Mortgage Loan Trust
         1998-A, Mortgage Pass-Through Certificates, Series 1998-A, without

         Merged Holder, if applicable;

                  (ii)  the original Mortgage, with evidence of recording
         thereon, provided, that if the original Mortgage has been delivered for

         of such original Mortgage so certified by the Seller, together with a
         certificate of the Depositor certifying that such original Mortgage has
         been so delivered to such recording office;

                  (iii) the original assignment of Mortgage, from the Seller to
         "Norwest Bank Minnesota, National Association, as trustee for the
         registered holders from time to time of FURST Mortgage Loan Trust
         1998-A, Mortgage Pass-Through Certificates, Series 1998-A," which
         assignment shall be in form and substance acceptable for recording;

                  (iv)  the original attorney's opinion of title or the original
         policy of title insurance, provided, that if any such original policy
         of title insurance has not yet been received by the Seller, the Seller
         shall cause to be delivered to the Document Custodian a copy of such
         policy or a title insurance binder or commitment for the issuance of
         such policy;

                  (v)   originals of all intervening assignments of Mortgage,
         with evidence of recording thereon, showing a complete chain of title
         from the originator to the Seller or to the Merged Holder, if
         applicable, provided, that if any such original intervening assignment
         of Mortgage has been delivered for recording to the appropriate public
         recording office of the jurisdiction in which the Mortgaged Property is
         located but has not yet been returned to the Seller by such recording
         office, the Seller may have delivered to the Document Custodian a
         certified true copy of such original assignment of Mortgage so
         certified by the Seller, together with a certificate of the Seller
         certifying that such original assignment of Mortgage has been so
         delivered to such recording office;

                  (vi)  originals of all assumption and modification agreements,
         if any; and

provided, however, the Seller may deliver to the Document Custodian all Related

                                       45
<PAGE>   51

         In all such instances, the Seller will deliver or cause to be delivered
the original recorded Mortgage and assignments thereof to the Document Custodian
promptly upon receipt of the original recorded Mortgage.

         For all Initial Mortgage Loans that were owned by the Seller on the
Initial Cut-Off Date as successor by merger to the originator or previous
holder, the Seller shall deliver to the Trustee, as Document Custodian, on or
before the Closing Date, an officer's certificate identifying such Initial
Mortgage Loans and the identities of the Persons (each, a "Merged Holder") that
are reflected on the related Mortgage Notes and Mortgage or assignment of
Mortgage as the holder, certifying that the Seller is successor by merger to
each such Merged Holder and certifying as to the authority of the officer
signing the endorsement referred to in clause (i) above and the assignment of
Mortgage referred to in clause (iii) above to execute the same. Such officer's
certificate shall constitute part of the Mortgage File of each such Initial
Mortgage Loan.

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

         In connection with such assignment, transfer, sale and conveyance, the
Seller shall file, on or prior to the Closing Date, in the appropriate office of
any applicable state, county or other relevant jurisdiction, a UCC-1 financing
statement executed by the Seller as debtor, naming the Depositor as secured
party (and indicating that the security interest in such loans has been assigned
to the Trustee) and listing as collateral the Mortgages, the Mortgage Notes, the
Related Documents and other property constituting the Trust. The
characterization of the Seller as "debtor" and the Depositor as "secured party"
in any such financing statement is solely for protective purposes and shall in
no way be construed as being contrary to the intent of the parties that the
transfer of the Mortgage Loans by the Seller to the Depositor and the transfer
of the Mortgage Loans by the Depositor to the Trust be treated as a sale to the
Depositor and the Trust, respectively, of the respective Seller's entire right,
title and interest in and to the property specified in the preceding sentence.
In connection with such filing, the Seller shall cause to be filed all necessary
continuation statements thereof and amendments thereto and take or cause to be
taken such actions and execute such documents as are necessary to continue the
perfection and protect the Certificateholders' interest in such property.

         (b) The Seller shall use its best efforts, within 180 days of the
Closing Date with respect to the Initial Mortgage Loans and of the applicable
Subsequent Transfer Date with respect to Subsequent Mortgage Loans, at its own
expense, to either (i) record the assignment of



                                       46
<PAGE>   52

each Mortgage in favor of the Trustee in the appropriate real property office or
other records office or (ii) deliver to the Trustee the assignment of each
Mortgage in favor of the Trustee in form for recordation, together with an
Opinion of Counsel to the effect that recording is not required to protect the
Trustee's right, title and interest in and to the related Mortgage Loan or, in
the event a court should recharacterize the conveyance of the Mortgage Loans as
a loan or a security for a loan, to perfect a first priority security interest
in favor of the Trustee in the related Mortgage Loan. With respect to any
Assignment of Mortgage as to which the related recording information is
unavailable within the applicable time period set forth above, such Assignment
of Mortgage shall be submitted for recording within 30 days after receipt of
such information but in no event later than one year after the date such
Assignment of Mortgage is otherwise required to be recorded pursuant to this
Section. In the event that any such Assignment of Mortgage is lost or returned
unrecorded because of a defect therein, the Seller shall promptly prepare a
substitute Assignment of Mortgage or cure such defect, as the case may be, and
thereafter the Depositor shall be required to submit each such Assignment of
Mortgage for recording. Any failure of the Seller to comply with this Section
2.1(b) shall result in the obligation of the Seller to purchase or substitute
for the related Mortgage Loans pursuant to the provisions of Section 2.2.

         (c) The Document Custodian agrees, for the benefit of
Certificateholders and the Trustee, within 180 days after delivery to it of the
Mortgage Files and the Related Documents hereunder to review the Mortgage Files
(and deliver a certificate to the Servicer and the Seller as to the findings of
such review) to ascertain that all required documents set forth in paragraphs
(i) - (vi) of Section 2.1(a) have been executed and received, and that the
Mortgage Notes have been endorsed without recourse as specified in Section
2.1(a)(i), and that such documents relate to the Mortgage Loans identified on
the Mortgage Loan Schedule and in so doing the Document Custodian may rely on
the purported due execution and genuineness of any signature thereon. Within 90
days of the Closing Date, the Document Custodian will deliver a certificate to
the Servicer and the Seller as to the status of such review. If within such
180-day period the Document Custodian finds any document constituting a part of
a Mortgage File not to have been executed or received or to be unrelated to the
Mortgage Loans identified in said Mortgage Loan Schedule or, if in the course of
its review, the Document Custodian determines that such Mortgage File is
otherwise defective in any material respect, the Document Custodian shall
promptly upon the conclusion of its review of all of the Mortgage Files notify
the Trustee, the Depositor, the Servicer and the Seller, and the Seller shall
have a period of 60 days after such notice within which to correct or cure any
such defect; provided, however, that if such defect shall not have been
corrected or cured within such 60-day period due primarily to the failure of the
related office of real property or other records to return any document
constituting a part of a Mortgage File, the Seller shall so notify the Document
Custodian and the Trustee in writing and the period during which such defect may
be corrected or cured shall be extended until such time as any such documents
are returned from such related office (in no event, however, will such period
extend beyond one (1) year from the date of discovery of such defect); provided,
that prior to any such extension the Seller shall deliver to the Document
Custodian a true copy of such document with a certification by the Seller on the
face of such copy substantially as follows: "certified true and correct copy of
original which has been transmitted for recordation."

         (d) The Document Custodian shall have no responsibility for reviewing
any Mortgage File except as expressly provided in subsection (c) of Section 2.1.
Without limiting 



                                       47
<PAGE>   53

the effect of the preceding sentence, in reviewing any Mortgage File pursuant to
such subsection, the Document Custodian and the Trustee shall have no
responsibility for determining whether any document is valid and binding,
whether the text of any assignment or endorsement is in proper or recordable
form (except, if applicable, to determine if the Trustee is the assignee),
whether any document has been recorded in accordance with the requirements of
any applicable jurisdiction, but shall only be required to determine whether a
document has been executed, that it appears to be what it purports to be, and,
where applicable, that it purports to be recorded, but shall not be required to
determine whether any Person executing any document is authorized to do so or
whether any signature thereon is genuine. In addition, with respect to documents
referred to in clause (vi) of Section 2.1(a), the Document Custodian shall only
be obligated to identify whether any such documents are included in the Mortgage
File for each Mortgage Loan.

         SECTION 2.2. ACCEPTANCE BY TRUSTEE; RETRANSFER OF MORTGAGE LOANS.

         (a) The Trustee hereby acknowledges the sale and assignment of the
Mortgage Loans and the Related Documents pursuant to the terms of this Agreement
and declares that the Trustee holds and will hold such documents (to the extent
required to be held by the Trustee hereunder) and all amounts received by it
thereunder and hereunder in trust, upon the terms herein set forth, for the use
and benefit of all present and future Certificateholders. The parties hereto do
hereby create and establish, pursuant to the laws of the State of North Carolina
and this Agreement, the Trust, which, for convenience, shall be known as "FURST
Mortgage Loan Trust 1998-A."

         (b) If the time to correct or cure any defect of which the Trustee or
the Document Custodian, as the case may be, has notified the Seller following
review of the Mortgage Files by the Trustee or the Document Custodian, as the
case may be, has expired without any correction or cure, the Seller shall, no
later than two Business Days immediately preceding the Distribution Date in the
month following the Collection Period in which the time to correct or cure such
defect expired, repurchase the related Mortgage Loan (including any property
acquired in respect thereof and any insurance policy or Insurance Proceeds with
respect thereto) from the Trust at a price equal to the Purchase Price, which
amount shall be deposited into the Collection Account pursuant to Section 3.2 on
such Business Day or substitute a Mortgage Loan (each, a "Substitute Mortgage
Loan") that is an Eligible Substitute Mortgage Loan for such Mortgage Loan in
accordance with Section 2.7. Promptly upon receipt by the Trustee of written
notification signed by a Servicing Officer to the effect that the Purchase Price
for any such Mortgage Loan has been so deposited into the Collection Account,
the Document Custodian shall release to the Seller the Mortgage File for the
repurchased Mortgage Loan and the Trustee shall execute and deliver to the
Seller an assignment substantially in the form of Exhibit E, without recourse,
in order to vest in the Seller legal and beneficial ownership of such
repurchased or removed Mortgage Loan (including any property acquired in respect
thereof and any insurance policy or Insurance Proceeds with respect thereto).
The form of assignment attached as Exhibit E may be modified from time to time
to the extent required by applicable law, as evidenced by an Opinion of Counsel
delivered to the Trustee, it being understood that the Trustee shall have no
responsibility for determining the sufficiency of such assignment for its
intended purpose. The obligation of the Seller to repurchase or substitute for
any Mortgage Loan shall constitute the sole remedy with respect to such defect
available to Certificateholders or the Trustee against the Seller on behalf of



                                       48
<PAGE>   54

Certificateholders. An Opinion of Counsel to the effect set forth in Section
2.7(d) shall be delivered to the Trustee in connection with any such repurchase.

         It is understood and agreed that the representations and warranties set
forth in this Section 2.5 shall survive delivery of the Mortgage Files to the

and warranties which materially and adversely affects the interests of the
Certificateholders, the Person discovering such breach shall give prompt written

         SECTION 2.6. REPRESENTATIONS AND WARRANTIES OF THE SELLER REGARDING
THIS AGREEMENT AND THE MORTGAGE LOANS; TRANSFER OF CERTAIN MORTGAGE LOANS.

         (a) The Seller represents and warrants to the Trustee on behalf of the
Certificateholders as follows as of the Closing Date with respect to the Initial
Mortgage Loans and as of each related Subsequent Transfer Date with respect to
the Subsequent Mortgage Loans transferred on such Subsequent Transfer Date:

                  (i)   The information with respect to each Mortgage Loan set
         forth in the Mortgage Loan Schedule is true and correct in all material
         respects as of the applicable Cut-Off Date;

                  (ii)  All of the Related Documents set forth in Section 2.1
         (including all material documents related thereto) will have been

         in Section 2.1. Each Mortgage File contains each of the documents and
         instruments specified to be included therein duly executed and in due
         and proper form, and each such document or instrument is in a form
         generally acceptable to prudent mortgage lenders that regularly
         originate or purchase mortgage loans comparable to the Mortgage Loans
         for sale to prudent investors in the secondary market that invest in
         mortgage loans such as the Mortgage Loans;

                  (iii) (A) Each Mortgaged Property is improved by a single
         (one-to-four) family residential dwelling, including, without
         limitation, condominiums, townhouses, planned unit developments,
         manufactured homes and mobile homes. Each mobile home and manufactured
         home constituting any portion of any Mortgaged Property constitutes
         real property under applicable state law; and (B) each mobile home
         constituting any portion of any Mortgaged Property is a Single-Family
         Residence;

                  (iv)  Each Mortgage Loan is being serviced by the Servicer;

                  (v)   Each Mortgage Note has a fixed rate of interest and an
         original term to maturity of not more than 30 years from the date on
         which the first monthly payment was due. Each Mortgage Note with
         respect to the Mortgage Loans will provide for a schedule of
         substantially level and equal Monthly Payments which are sufficient to


                                       54

         amortize fully the principal balance of such Mortgage Loan over a
         period of time equal to the amortization period of such Mortgage Note;

                  (vi)   Each Mortgage is a valid and subsisting first lien of
         record on the Mortgaged Property subject to the exceptions to title set
         forth in the title insurance policy or attorney's opinion, as the case
         may be, with respect to the related Mortgage Loan, which exceptions are
         generally acceptable to mortgage lending companies, and such other
         exceptions to which similar properties are commonly subject and which
         do not individually, or in the aggregate, materially and adversely
         affect the benefits of the security intended to be provided by such
         Mortgage. Any security agreement, chattel mortgage or equivalent
         document related to the Mortgage and delivered to the Document
         Custodian on behalf of the Trustee establishes in the Seller a valid
         and subsisting first lien and first priority security interest on the
         property described therein, and the Seller has full right to assign the
         same to the Trustee;

                  (vii)  Except with respect to liens released immediately prior
         to the transfer herein contemplated, each Mortgage Note and related
         Mortgage have not been assigned or pledged and immediately prior to the
         transfer and assignment herein contemplated, the Seller held good,
         marketable and indefeasible title to, and was the sole owner and holder
         of, each Mortgage Loan subject to no Liens; the Seller has full right
         and authority under all governmental and regulatory bodies having
         jurisdiction over the Seller, subject to no interest or participation
         of, or agreement with, any party, to sell and assign the same pursuant
         to this Agreement; and immediately upon the transfer and assignment
         herein contemplated, the Seller shall have transferred all of its
         right, title and interest in and to each Mortgage Loan to the Depositor
         (or its assignee) and the Depositor (or its assignee) will hold good,
         marketable and indefeasible title, to, and be the sole owner of, each
         Mortgage Loan subject to no Liens;

                  (viii) None of the Initial Mortgage Loans were delinquent
         (i.e. not 30 or more days past due) as of the Initial Cut-Off Date and
         none of the Subsequent Mortgage Loans were delinquent as of the
         applicable Subsequent Transfer Date; none of the Mortgage Loans has
         ever been delinquent in payment for 60 or more days nor more than once
         during the twelve months preceding the applicable Cut-Off Date been
         delinquent in payment for 30 or more days;

                  (ix)   To the best knowledge of the Seller, there is no
         delinquent tax, fee or assessment lien on any Mortgaged Property;

                  (x)    No Mortgage Loan is subject to any right of rescission,
         set-off, counterclaim or defense, including the defense of usury, nor
         will the operation of any of the terms of any Mortgage Note or
         Mortgage, or the exercise of any right thereunder, render either the
         Mortgage Note or the Mortgage unenforceable in whole or in part, or
         subject to any right of rescission, set-off, counterclaim or defense,
         including the defense of usury, and no such right of rescission,
         set-off, counterclaim or defense has been asserted with respect
         thereto;



                                       55

                  (xi)   (A) There is no mechanics' lien or claim for work,
         labor or material affecting the Mortgaged Property which is or may be a
         lien prior to, or equal or coordinate with, the lien of the related
         Mortgage except those liens which are fully insured against by the
         title insurance policy referred to in clause (xiii) below; and (B) to
         the best of its knowledge, each Mortgaged Property is free of material
         damage and is in good repair;

                  (xii)  Each Mortgage Loan at the time it was made complied in
         all material respects with applicable state and federal laws and
         regulations, including, without limitation, usury, equal credit
         opportunity, real estate settlement procedures, consumer credit,
         truth-in-lending and disclosure laws and consummation of the
         transactions contemplated hereby, including, without limitation, the
         receipt of interest, will not involve the violation of any such laws;

                  (xiii) Either an attorney's opinion of title has been obtained
         or a lender's title insurance policy or binder issued in standard
         American Land Title Association form by a title insurance company
         authorized to transact business in the state in which the related
         Mortgaged Property is situated in an amount at least equal to the
         original principal balance thereof insuring the Seller, its successor
         and assigns as to the first priority of the lien of the Mortgage,
         subject only to the exceptions of the character referred to in (vi)
         above, and the Seller is the sole insured of such lender's title
         insurance policy, and each such policy or binder is valid and remains
         in full force and effect, and a title search or other assurance of
         title customary in the relevant jurisdiction was obtained with respect
         to each Mortgage Loan as to which no title insurance policy or binder
         was issued;

                  (xiv)  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 representing coverage described in Section 3.5;

                  (xv)   A flood insurance policy is in effect with respect to
         each Mortgaged Property with a generally acceptable carrier in an
         amount representing coverage described in Section 3.5, if and to the
         extent required by Section 3.5;

                  (xvi)  Each Mortgage and Mortgage Note is the legal, valid and
         binding obligation of the related Mortgagor and is enforceable by the
         Trustee or any co-trustee appointed hereunder against the Mortgagor in
         accordance with its terms, except only as such enforcement may be
         limited by bankruptcy, insolvency, reorganization, moratorium or other
         similar laws affecting the enforcement of creditors' rights generally
         and by general principles of equity (whether considered in a proceeding
         or action in equity or at law), and all parties to each Mortgage Loan
         and the Mortgagee had full legal capacity to execute all Mortgage Loan
         documents and to convey the estate therein purported to be conveyed;



                                       56
<PAGE>   62

                  (xvii)  All individual insurance policies contain a standard
         mortgagee clause naming the Seller, its successors and assigns, as
         mortgagee. All premiums thereon have been paid. Each Mortgage obligates
         the Mortgagor thereunder to maintain all such 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;

                  (xviii) The terms of the Mortgage Note and the Mortgage have
         not been impaired, altered or modified in any material respect, except
         by a written instrument which has been recorded or is in the process of
         being recorded, if necessary, to protect the interests of the
         Certificateholders and which has been or will be delivered to the
         Document Custodian on behalf of the Trustee. Each original Mortgage was
         recorded, and all subsequent assignments of the original Mortgage
         (other than the assignment to the Trustee) have been recorded in the
         appropriate jurisdictions wherein such recordation is necessary to
         perfect the lien thereof as against creditors of the Seller, or is in
         the process of being recorded;

                  (xix)   No instrument of release or waiver has been executed
         in connection with any Mortgage Loan, and no Mortgagor has been
         released, in whole or in part;

                  (xx)    No Mortgage Note permits or obligates the Seller to
         make future advances to the related Mortgagor at the option of the
         Mortgagor. There are no defaults in complying with the terms of the
         Mortgage, and either (1) any taxes, governmental assessments, insurance
         premiums, water, sewer and municipal charges or ground rents which
         previously became due and owing have been paid, or (2) 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 payments in the nature of escrow
         payments, including without limitation, taxes and insurance payments,
         the Seller 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 Note, [except for interest accruing from the date of the
         Mortgage Note or date of disbursement of the Mortgage proceeds,
         whichever is greater, to the day which precedes by one month the Due
         Date of the first installment of principal and interest];

                  (xxi)   To the best knowledge of the Seller, there is no
         proceeding pending or threatened for the total or partial condemnation
         of any Mortgaged Property, nor is such a proceeding currently
         occurring, and such property is undamaged by waste, fire, earthquake or
         earth movement, windstorm, flood, tornado or other casualty, so as to
         affect adversely the value of the Mortgaged Property as security for
         the Mortgage Loan or the use for which the premises were intended;

                  (xxii)  To the best of its knowledge, no improvement located
         on or being part of any Mortgaged Property is in violation of any
         applicable zoning law or regulation. All inspections, licenses and
         certificates required to be made or issued with respect to all 



                                       57
<PAGE>   63

         occupied portions of each 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 and such Mortgaged
         Property is lawfully occupied under the applicable law;

                  (xxiii)  The proceeds of each Mortgage Loan have been fully
         disbursed, and there is no obligation on the part of the mortgagee to
         make future advances thereunder. 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;

                  (xxiv)   No Mortgage Loan was originated under a buydown plan
         or under a limited documentation program or is in violation of the Home
         Ownership and Equity Protection Act of 1994;

                  (xxv)    There is no obligation on the part of the Seller or
         any other party to make payments in addition to those made by the
         Mortgagor;

                  (xxvi)   No Mortgage Loan has a shared appreciation feature,
         or other contingent interest feature;

                  (xxvii)  Each Mortgage contains customary and enforceable
         provisions which render the rights and remedies of the holder thereof
         adequate for the realization against the related Mortgaged Property of
         the benefits of the security, including, (A) in the case of a Mortgage
         designated as a deed of trust, by trustee's sale, and (B) otherwise by
         judicial or non-judicial foreclosure. To the Seller's best knowledge,
         there is no homestead or other exemption available to the related
         Mortgagor which would materially interfere with the right to sell the
         Mortgaged Property at a trustee's sale or the right to foreclose the
         Mortgage except as set forth in the Prospectus;

                  (xxviii) Except for Mortgage Loans that are delinquent for a
         time period less than 30 days, there is no default, breach, violation
         or event of acceleration existing under any Mortgage or the related
         Mortgage Note and no 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; and neither the
         Seller, nor any other entity involved in originating or servicing a
         Mortgage Loan, has waived any default, breach, violation or event of
         acceleration;

                  (xxix)   All amounts received after the applicable Cut-Off
         Date with respect to the Mortgage Loans to which the Seller is not
         entitled have been deposited into the Collection Account and are, as of
         the Closing Date or the Subsequent Transfer Date, as applicable, in the
         Collection Account;

                  (xxx)    Each of the Mortgage Loans was originated
         substantially in accordance with the credit underwriting guidelines of
         the Seller, which are at least as



                                       58
<PAGE>   64

         stringent as the underwriting criteria set forth in the Prospectus and
         the Prospectus Supplement;

                  (xxxi)   Each Mortgage Loan conforms, and all Mortgage Loans
         in the aggregate conform, in all material respects, to the description
         thereof set forth in the Prospectus Supplement; each Mortgage Note and
         Mortgage is in substantially the form of Exhibit F hereto;

                  (xxxii)  The Mortgage Loans were not selected by the Seller
         for inclusion in the Trust on any basis intended to adversely affect
         the Trust;

                  (xxxiii) Each Mortgage Loan was originated based upon an
         appraisal of the related Mortgaged Property; each such appraisal is on
         a Fannie Mae-approved form signed prior to the approval of such
         Mortgage Loan application by a qualified appraiser, appointed by the
         Seller or the originator of such Mortgage Loan, as appropriate, who has
         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 such Mortgage Loan;

                  (xxxiv)  Each Mortgage Loan was originated by the Seller or an
         affiliate of the Seller or purchased by the Seller;

                  (xxxv)   (A) Each Mortgaged Property is located in the state

         four-family dwelling, a condominium unit, a mobile, manufactured or
         modular home, a townhouse or a unit in a planned unit development).
         With respect to the Initial Cut-Off Date Aggregate Loan Balance, (a) at

         those enumerated in clause (a), (b) or (c) above; and (B) as of the
         Initial Cut-Off Date, no more than 1.3021% of the Initial Mortgage

         Loan Balance, 4.05% of the Initial Mortgage Loans (by Initial Cut-Off

         investor-owned and vacation);

                  (xxxviii) The Mortgage Note is not and has not been secured by
         any collateral, pledged account or other security except the lien of
         the corresponding Mortgage and the security interest of any applicable
         security agreement or chattel mortgage referred to in (vi) above;

                  (xxxix)   Each Initial Mortgage Loan was originated on or

                  (xl)      The Seller has not transferred the Mortgage Loans to
         the Depositor with any intent to hinder, delay or defraud any of its
         creditors;

                  (xli)     To the best knowledge of the Seller, all parties
         which have had any interest in the Mortgage Loan, whether as

         respect of the origination, modification or amendment of any Mortgage
         Loan has taken place on the part of any Person, including, without

                  With respect to the representations and warranties set forth
in this Section 2.6(a) that are made to the best of the Seller's knowledge or as
to which the Seller has no knowledge, if it is discovered by the Seller, the
Servicer, the Depositor, the Trustee or the Document Custodian that the
substance of such representation and warranty is inaccurate and such inaccuracy
materially and adversely affects the value of the related Mortgage Loan then,
notwithstanding the Seller's lack of knowledge with respect to the substance of
such representation and warranty being inaccurate at the time the representation
or warranty was made, such inaccuracy shall be deemed a breach of the applicable
representation or warranty.

         (b) The representations and warranties set forth in Section 2.6(a)
shall survive the delivery of the Mortgage Files to the Document Custodian or
the Trustee. Upon discovery by the Seller, the Servicer, the Depositor or the
Trustee of a breach of any of the foregoing representations and warranties with
respect to any Mortgage Loan, the party discovering such breach shall give
written notice thereof to the other parties within five (5) days after such


                                       61
<PAGE>   67

discovery but only to the extent that such breach materially and adversely
affects the interests of Certificateholders. Promptly after its discovery or its
receipt of notice of any such breach, the Seller shall use all reasonable
efforts to cure such breach in all material respects. Unless at the expiration
of the 60-day period following receipt of such notice, such breach has been
cured in all material respects or otherwise does not exist or continue to exist,
the Seller shall, not later than two Business Days immediately preceding the
Distribution Date in the month following the related Collection Period in which
any such cure period expired (but in the case of a breach that if discovered
before the Startup Day, would have prevented the obligation from being a
"qualified mortgage" as defined in the Code, within 90 days of discovery of the
breach), but only to the extent that such uncured breach materially and
adversely affects the interests of the Certificateholders, repurchase at the
Purchase Price such Defective Mortgage Loan (including any property acquired in
respect thereof and any insurance policy or Insurance Proceeds with respect
thereto) in the same manner and subject to the same conditions as set forth in
Section 2.2 or shall substitute an Eligible Substitute Mortgage Loan in
accordance with Section 2.7. Upon making any such repurchase, the Seller shall
be entitled to receive an assignment of the repurchased or removed Mortgage Loan
and a release of the related Mortgage File from the Document Custodian to the
extent set forth in Section 2.2. The obligation of the Seller to repurchase or
replace any Mortgage Loan as to which a breach has occurred and is continuing
shall constitute the sole remedy against the Seller with respect to such breach
available to Certificateholders or the Trustee on behalf of Certificateholders.

         SECTION 2.7. SUBSTITUTION OF MORTGAGE LOANS.

         (a) On a Determination Date within two years following the Closing Date
and which is on or before the date on which the Seller would otherwise be
required to repurchase a Mortgage Loan under this Article II, the Seller may
deliver to the Trustee one or more Eligible Substitute Mortgage Loans in
substitution for any one or more of the Defective Mortgage Loans which the
Seller would otherwise be required to repurchase pursuant to this Article II. In
connection with any such substitution, the Seller shall calculate the
Substitution Adjustment Amount, if any, and shall deposit such amount, along
with the Unreimbursed Advances, unreimbursed Servicing Advances and unpaid
Servicing Fee with respect to the Defective Mortgage Loan to the Collection
Account on or before the second Business Day prior to the Distribution Date in
the month succeeding the calendar month during which the related Mortgage Loan
became required to be purchased or replaced hereunder.

         (b) The Seller shall notify the Servicer and the Trustee in writing not
less than five Business Days before the related Determination Date which is on
or before the date on which the Seller would otherwise be required to repurchase
such Mortgage Loan pursuant to this Article II of its intention to effect a
substitution under this Section. On such Determination Date (the "Substitution
Date"), the Seller shall deliver to the Trustee, with a copy to the Servicer
(except as to (1) below), (1) the Eligible Substitute Mortgage Loans to be
substituted for the original Mortgage Loans, (2) a list of the original Mortgage
Loans to be substituted for by such Eligible Substitute Mortgage Loans in the
same format as required for the list provided on the Closing Date, (3) an
Officers' Certificate (A) stating that no default by the Servicer described in
Section 8.1 shall have occurred and be continuing, (B) stating that the
aggregate principal balance of all Eligible Substitute Mortgage Loans
(determined with respect to each Eligible Substitute



                                       62
<PAGE>   68


Mortgage Loan as of the Determination Date on which it was substituted)
including the principal balance of Eligible Substitute Mortgage Loans being
substituted on such Determination Date does not exceed an amount equal to 10% of
the Initial Collateral Balance as of the Closing Date, (C) stating that all
conditions precedent to such substitution specified in subsection (a) have been
satisfied and that each such substituted Mortgage Loan constitutes an Eligible
Substitute Mortgage Loan and attaching as an exhibit a supplemental Mortgage
Loan Schedule (the "Supplemental Mortgage Loan Schedule") setting forth the same
type of information as appears on the Mortgage Loan Schedule and representing as
to the accuracy thereof and (D) confirming that the representations and
warranties contained in Section 2.6 are true and correct in all material
respects with respect to the Eligible Substitute Mortgage Loans on and as of
such Determination Date, provided that remedies for the inaccuracy of such
representations are limited as set forth in Section 2.6 and this Section 2.7,
(4) a Nondisqualification Opinion to the effect set forth below and (5) a
certificate stating that cash in the amount of the related Substitution
Adjustment Amount, if any, has been deposited to the Collection Account. Upon
receipt of the foregoing, the Trustee shall release such original Mortgage Loans
to the Seller.

         (c) Concurrently with the satisfaction of the conditions set forth in
Section 2.7(a) and (b) above and the transfer of such Eligible Substitute
Mortgage Loans to the Trustee pursuant to Section 2.7(a) above, Exhibit D to
this Agreement shall be deemed to be amended to exclude all Mortgage Loans being
replaced by such Eligible Substitute Mortgage Loans and to include the
information set forth on the Supplemental Mortgage Loan Schedule with respect to
such Eligible Substitute Mortgage Loans, and all references in this Agreement to
Mortgage Loans shall include such Eligible Substitute Mortgage Loans and be
deemed to be made on or after the related Substitution Date, as the case may be,
as to such Eligible Substitute Mortgage Loans.

         (d) In connection with any Mortgage Loan that the Seller is required to
purchase or replace, the Seller shall deliver to the Trustee a
Nondisqualification Opinion to the effect that such purchase or substitution
will not cause (x) any federal tax to be imposed on the Trust, including without
limitation, any Federal tax imposed on "prohibited transactions" under Section
860F(a)(1) of the Code or on "contributions after the start-up day" under
Section 860G(d)(1) of the Code or (y) any portion of the Trust to fail to
qualify as a REMIC at any time that any Certificate is outstanding. In the event
that such opinion indicates that a repurchase or substitution will result in the
imposition of a prohibited transaction tax, give rise to net taxable income or
be deemed a contribution to the REMIC after the "start-up day," the Seller shall
not be required to repurchase or replace any such Mortgage Loan unless and until
the Servicer has determined there is an actual or reasonably foreseeable default
with respect thereto.

         SECTION 2.8. EXECUTION AND AUTHENTICATION OF CERTIFICATES.

         The Trustee on behalf of the Trust shall cause to be executed,
authenticated and delivered on the Closing Date to or upon the order of the
Depositor, in exchange for the Mortgage Loans, concurrently with the sale,
assignment and conveyance to the Trustee of the Mortgage Loans, each Class of
Certificates in authorized denominations.



                                       63
<PAGE>   69

         SECTION 2.9. REMIC PROVISIONS.

         (a) This Agreement shall be construed so as to carry out the intention
of the parties that each of REMIC I and REMIC II be treated as a REMIC at all
times prior to the date on which the Trust is terminated. The "regular
interests" (within the meaning of Section 860G(a)(1) of the Code) in REMIC II
shall consist of the Class SA-1 Certificates, the Class SA-2 Certificates, the
Class SA-3 Certificates, the Class SA-4 Certificates, the Class SA-5
Certificates, the Class SA-X Certificates, the Class A-1 Certificates, the Class
A-2 Certificates, the Class A-3 Certificates, the Class A-4 Certificates, the
Class A-5 Certificates, the Class A-6 Certificates, the Class A-7 Certificates,
the Class A-X Certificates, the Class M Certificates, the Class B-1
Certificates, the Class B-2 Certificates, the Class B-3 Certificates, the Class
B-4 Certificates and the Class B-5 Certificates. The "residual interest" (within
the meaning of Section 860(G)(a)(2) of the Code) in REMIC II shall consist of
the Class R-II Certificate. The "regular interests" (within the meaning of
Section 860(G)(a)(1) of the Code) of REMIC I shall consist of the Class SA-1
Regular Interest, the Class SA-2 Regular Interest, the Class SA-3 Regular
Interest, the Class SA-4 Regular Interest and the Class SA Subordinate Regular
Interest each of which will have an interest rate equal to the Group SA Net WAC
and the Class A-1 Regular Interest, the Class A-2 Regular Interest, the Class
A-3 Regular Interest, the Class A-4 Regular Interest, the Class A-5 Regular
Interest, the Class A-7 Regular Interest and the Class A Subordinate Regular
Interest each of which will have an interest rate equal to the Group A Net WAC.
The "residual interest" (within the meaning of Section 860(G)(a)(2) of the Code)
of REMIC I shall consist of the Class R-I Certificate.

         (b) The original principal balance of the Class SA Subordinate Regular
Interest is equal to the original Group SA Subordinate Amount less $25.00. The
original principal balance of the Class A Subordinate Regular Interest is equal
to the original Group A Subordinate Amount less $25.00. The original principal
balance of each of the principal-bearing Class SA and Class A Regular Interests
other than the Class SA and Class A Subordinate Regular Interests is equal to
the original principal balance of the principal-bearing Certificate of REMIC II
which has the same designation.

         (c) The Trustee shall provide to the Internal Revenue Service and to
the Person described in Section 860E(e)(3) and (6) of the Code the information
described in Treasury Regulation Section 1.860D-1(b)(5)(ii), or any successor
regulation thereto with respect to each REMIC. Such information will be provided
in the manner described in Treasury Regulation Section 1.860E-2(a)(5), or any
successor regulation thereto.

         (d) For federal income tax purposes, the Final Scheduled Distribution
Date for each Class of the Certificates is hereby set to be the Distribution
Date indicated below:

         (e) The Closing Date is hereby designated as the "startup day" of each
REMIC within the meaning of Section 860G(a) (9) of the Code.

         SECTION 2.10. SUBSEQUENT TRANSFERS.

         (a) Subject to the satisfaction of the conditions set forth in Section
2.1 and paragraph (b) below and pursuant to the terms of the related Subsequent
Transfer Agreement, in consideration of the Trustee's delivery on the relevant
Subsequent Transfer Dates, on behalf of the Depositor, to or upon the order of
the Seller of all or a portion of the balance of funds in the Pre-Funding
Account, the Depositor will use its best efforts to cause the Seller to, and the
Seller shall, on any Subsequent Transfer Date, on behalf of the Depositor, sell,
transfer, assign, set over and otherwise convey without recourse, to the
Trustee, all right, title and interest of the Seller in and to each Subsequent
Mortgage Loan listed on the Subsequent Mortgage Loan Schedule



                                       65
<PAGE>   71

delivered by the Seller on such Subsequent Transfer Date, including without
limitation the related Cut-Off Date Loan Balance and (i) all interest accruing
thereon on and after the related Subsequent Cut-Off Date and all collections in
respect of interest and principal received on and after the Subsequent Cut-Off
Date (exclusive of payments in respect of interest on the Subsequent Mortgage
Loans accrued prior to the Subsequent Cut-Off Date and received thereafter);
(ii) property which secured such Subsequent Mortgage Loan and which has been
acquired by foreclosure or deed in lieu of foreclosure; (iii) its interest in
any insurance policies in respect of such Subsequent Mortgage Loan; and (iv) all
proceeds of the foregoing. The transfer by the Seller of the Subsequent Mortgage
Loans set forth on the Subsequent Mortgage Loan Schedule to the Trustee shall be
absolute and shall be intended by the Seller and all parties hereto to be
treated as a sale by the Seller to the Trust. If the assignment and transfer of
the Mortgage Loans and the other property specified in this Section 2.10 from
the Seller to the Trustee pursuant to this Agreement is held or deemed not to be
a sale or is held or deemed to be a pledge of security for a loan, the Seller
intends that the rights and obligations of the parties shall be established
pursuant to the terms of this Agreement and that, in such event, (1) the Seller
shall be deemed to have granted and does hereby grant to the Trustee as of the
related Subsequent Transfer Date a first priority security interest in the
entire right, title and interest of the Seller in and to the Subsequent Mortgage
Loans and all other property conveyed to the Trustee pursuant to this Section
2.10 and all proceeds thereof, and (2) this Agreement shall constitute a
security agreement under applicable law. Within 5 days of the Subsequent
Transfer Date, the Seller shall file in the appropriate office of any applicable
state, county or other relevant jurisdiction, a UCC-1 financing statement
executed by the Seller as debtor, naming the Trustee as secured party and
listing as collateral the Subsequent Mortgage Loans, the related Mortgage Notes
and other Related Documents. The amount paid by the Trustee on behalf of the
REMIC I from the Pre-Funding Account with respect to a Subsequent Mortgage Loan
shall be one-hundred percent (100%) of the related Cut-Off Date Loan Balance of
the Subsequent Mortgage Loan so transferred.

         (b) The Seller shall transfer and deliver to the Trustee the Subsequent
Mortgage Loans, and the other property and rights related thereto described in
paragraph (a) above, only upon the satisfaction of each of the following
conditions on or prior to the related Subsequent Transfer Date:

                  (i)   The Seller shall have provided the Trustee an Addition
         Notice, which notice shall be given not less than three Business Days
         prior to the related Subsequent Transfer Date and shall designate the
         Subsequent Mortgage Loans to be sold to the Trust and the aggregate
         Cut-Off Date Loan Balances of such Subsequent Mortgage Loans;

                  (ii)  The Seller shall have delivered to the Trustee a duly
         executed Subsequent Transfer Agreement;

                  (iii) The Seller shall have deposited in the Collection
         Account all principal collected and all interest accrued and collected
         in respect of such Subsequent Mortgage Loans on and after the related
         Subsequent Cut-Off Date;



                                       66
<PAGE>   72

                  (iv)   The Seller shall have delivered an Officer's
         Certificate to the Trustee confirming that as of each Subsequent
         Transfer Date, the Seller was not insolvent, nor will it be made
         insolvent by such transfer, nor is it aware of any pending insolvency;

                  (v)    The Seller shall have delivered an Officer's
         Certificate to the Trustee confirming that the Funding Period shall not
         have ended;

                  (vi)   The Seller shall have delivered to the Trustee an
         Officer's Certificate confirming the satisfaction of each condition
         precedent specified in this paragraph (b) and in the related Subsequent
         Transfer Agreement and that each Subsequent Mortgage Loan meets the
         eligibility requirements specified in the definition thereof for
         transfer;

                  (vii)  The Seller shall have delivered an Officer's
         Certificate to the Trustee confirming that the representations and
         warranties of the Seller pursuant to Section 2.5 and pursuant to
         Section 2.6(a) are true and correct with respect to the Seller and the
         Subsequent Mortgage Loans as of the Subsequent Transfer Date; and

                  (viii) The Seller shall have provided the Trustee with an
         Opinion of Counsel, acceptable to the Trustee, relating to the sale of
         the Subsequent Mortgage Loans to the Trustee.

         (c) In connection with each Subsequent Transfer Date and on the first
and second Distribution Dates the Trustee shall determine (i) the amount and
correct dispositions of the Capitalized Interest Requirement, Overfunded
Interest Amount and Pre-Funding Account Earnings for such Distribution Date in
accordance with the provisions of Section 4.2 and (ii) any other necessary
matters in connection with the administration of the Pre-Funding Account and of
the Capitalized Interest Account. In the event that any amounts are released as
a result of calculation error by the Trustee, or any assumption on which any
calculation is based proves to be incorrect, from the Pre-Funding Account or
from the Capitalized Interest Account, the Trustee shall not be liable therefor,
and the Seller, on behalf of the Depositor, shall immediately repay such amounts
to the Trustee.


                                   ARTICLE III

                          ADMINISTRATION AND SERVICING
                                OF MORTGAGE LOANS

         SECTION 3.1. THE SERVICER.

         (a) It is intended that the Trust formed hereunder shall consist of the
REMIC I and REMIC II and that the affairs of the Trust shall be conducted so as
to qualify each of the REMIC I and REMIC II as a "real estate mortgage
investment conduit" as defined in and in accordance with the REMIC Provisions.
In furtherance of such intentions, the Servicer covenants and agrees



                                       67
<PAGE>   73

that it shall not knowingly or intentionally take any action or omit to take any
action that would cause the termination of the REMIC status of any REMIC in the
Trust.

         (b) The Servicer shall service and administer the Mortgage Loans in a
manner consistent with the terms of this Agreement and with general industry
practice and shall have full power and authority, acting alone or through a
Subservicer, to do any and all things in connection with such servicing and
administration which it may deem necessary or desirable, it being understood,
however, that the Servicer shall at all times remain responsible to the Trustee
and the Certificateholders for the performance of its duties and obligations
hereunder in accordance with the terms hereof and any amounts in respect of the
Mortgage Loans received by any such Subservicer shall be deemed to have been
received by the Servicer whether or not actually received by it. Without
limiting the generality of the foregoing, the Servicer shall continue, and is
hereby authorized and empowered by the Trustee, to execute and deliver, in
connection with the Trust taking possession of any Mortgaged Property or upon
receipt from the Mortgagor of the amounts owed under the related Mortgage Loan
and upon delivery of written notice to the Trustee, on behalf of itself, the
Certificateholders and the Trustee 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. The Trustee shall upon written request of a
Servicing Officer furnish the Servicer with any powers of attorney and other
documents necessary or appropriate to enable the Servicer to carry out its
servicing and administrative duties hereunder, which powers of attorney or other
documents shall be prepared by the Servicer.

         The relationship of the Servicer (and of any successor to the Servicer
as servicer and any Subservicer under this Agreement) to the Trustee under this
Agreement is intended by the parties to be that of an independent contractor and
not that of a joint venturer, partner or agent.

         (c) In the event that the rights, duties and obligations of the
Servicer are terminated hereunder, any successor to the Servicer in its sole
discretion may, to the extent permitted by applicable law, terminate the
existing subservicer arrangements with any subservicer or assume the terminated
Servicer's rights under such subservicing arrangements which termination or
assumption will not violate the terms of such arrangements.

         (d) [RESERVED]

         (e) The Servicer may agree to changes in the terms of a Mortgage Loan
that would not cause the REMIC I or REMIC II to fail to qualify as a REMIC, as
evidenced by a Nondisqualification Opinion delivered by the Servicer to the
Trustee prior to the effective date of any such change, provided, however, that
such changes (i) do not adversely affect the interests of Certificateholders,
(ii) are consistent with prudent business practice, as evidenced by an Officer's
Certificate, substantially in the form of Exhibit G, delivered by the Servicer
to the Trustee prior to such effective date, (iii) do not extend the maturity
date of such Mortgage Loan in excess of one year, and (iv) do not result in any
change of the Loan Rate of such Mortgage Loan.

         (f) [RESERVED]



                                       68
<PAGE>   74

         (g) The Servicer may enter into subservicing agreements for any
servicing and administration of Mortgage Loans with any institution which is in
compliance with the laws of each state necessary to enable it to perform its
obligations under such subservicing agreement and (1) has been designated as an
approved Seller/Servicer by FHLMC or Fannie Mae, or (2) is an Affiliate of the
Servicer. The Servicer shall give notice to the Trustee of the appointment of
any Subservicer. Any subservicing arrangement shall be consistent with and not
violate the provisions of this Agreement. The Servicer shall not be relieved of
its obligations under this Agreement notwithstanding any such arrangement or any
of the provisions of this Agreement relating to arrangements between the
Servicer and a Subservicer or otherwise, and the Servicer shall be obligated to
the same extent and under the same terms and conditions as if the Servicer alone
were servicing and administering the Mortgage Loans. Any such arrangement shall
be deemed to be between the Subservicer and the Servicer alone and the Trustee
and the Trust shall not be deemed a party thereto and shall have no claims,
rights, obligations, duties or liabilities with respect to any Subservicer.

         (h) The Servicer and all Subservicers shall be deemed a single entity
for the purpose of determining compliance with the terms of this Agreement and
the Servicer shall be deemed to have received Principal Collections and Interest
Collections on the Mortgage Loans when any Subservicer has received such
Principal Collections and Interest Collections.

         SECTION 3.2. COLLECTION OF CERTAIN MORTGAGE LOAN PAYMENTS.

         (a) The Servicer shall make reasonable efforts to collect all payments
called for under the terms and provisions of the Mortgage Loans, and shall, to
the extent such procedures shall be consistent with this Agreement, follow such
collection procedures as it follows with respect to mortgage loans in its
servicing portfolio comparable to the Mortgage Loans. Consistent with the
foregoing, and without limiting the generality of the foregoing, the Servicer
may in its discretion (i) waive any late payment charge or any assumption fees
or other fees which may be collected in the ordinary course of servicing such
Mortgage Loan and (ii) arrange with a Mortgagor a schedule for the payment of
interest due and unpaid; provided, that such arrangement is consistent with the
Servicer's policies with respect to the mortgage loans it owns or services;
provided, further, that notwithstanding such arrangement such Mortgage Loans
will be included in the information regarding delinquent Mortgage Loans set
forth in the Servicing Certificate and monthly statement to Certificateholders
pursuant to Section 5.2.

         (b) The Servicer shall establish and maintain a separate account (the
"Collection Account") which may, as provided in Section 3.2(d), be maintained as
a deposit account with the Seller, provided that, upon the occurrence and
continuance of the failure of any of the events described in clauses (i) or (ii)
of Section 3.2(d), the Collection Account shall be established and maintained
with an entity meeting the requirements of the definition of "Eligible Account",
as a separate trust account titled "Norwest Bank Minnesota, National
Association, as Trustee, in trust for the registered holders of FURST Mortgage
Pass-Through Certificates, Series 1998-A." Funds in the Collection Account in
respect of the Mortgage Loans in Loan Group SA and the Mortgage Loans in Loan
Group A and amounts withdrawn from the Collection Account attributable to each
of such Loan Groups shall be accounted for separately. The Servicer shall on the
Closing Date deposit any amounts representing payments on and any collections in
respect of



                                       69
<PAGE>   75

the Initial Mortgage Loans received as of the Initial Cut-Off Date and prior to
the Closing Date and due for periods after such Initial Cut-Off Date and
thereafter deposit within two Business Days following receipt thereof by the
Servicer the following payments and collections received or made by it (without
duplication):

                  (i)   all Interest Collections and Principal Collections
         (including any Payaheads received);

                  (ii)  Net Liquidation Proceeds net of any related Foreclosure
         Profit;

                  (iii) Insurance Proceeds;

                  (iv)  any amounts payable in connection with the repurchase of
         any Mortgage Loan and the Substitution Adjustment Amount pursuant to
         Article II hereof; and

                  (v)   any amount required to be deposited in the Collection
         Account pursuant to Sections 3.2(c), 3.4, 3.5, 3.7 or 3.13;

provided, however, with respect to each Collection Period, the Servicer shall be
permitted to retain from payments in respect of interest on the Mortgage Loans,
the Servicing Fee for such Collection Period and the amount of any Unreimbursed
Advances. The foregoing requirements respecting deposits to the Collection
Account are exclusive, it being understood that, without limiting the generality
of the foregoing, the Servicer need not deposit in the Collection Account
amounts representing Foreclosure Profits, fees (including annual fees) or late
charge penalties payable by Mortgagors, or amounts received by the Servicer for
the accounts of Mortgagors for application towards the payment of taxes,
insurance premiums, assessments and similar items. The Servicer may retain, as
additional servicing compensation, all Foreclosure Profits and fees and late
charge penalties collected from Mortgagors.

         The Seller shall deposit the amounts required to be deposited in
respect of Mortgage Loans purchased by the Seller pursuant to Sections 2.2 and
2.6 to the Collection Account no later than the date specified therein.

         (c) All funds in the Collection Account shall be held (i) uninvested or
(ii) invested at the direction of the Servicer in Eligible Investments. Any
investments of funds in the Collection Account shall mature or be withdrawable
at par on or prior to the second Business Day preceding the immediately
succeeding Distribution Date. Any investment earnings on funds held in the
Collection Account shall be for the account of the Servicer and may be withdrawn
from the Collection Account by the Servicer at any time. Any investment losses
on funds held in the Collection Account shall be for the account of the Servicer
and promptly upon the realization of such loss shall be contributed by the
Servicer to the Collection Account. Any references herein to amounts on deposit
in the Collection Account shall refer to amounts net of such investment
earnings.



                                       70
<PAGE>   76

         (d) Notwithstanding anything in this Agreement to the contrary, (i) for
so long as (A) the Servicer remains an Affiliate of the Seller, (B) no Event of
Default shall have occurred and be continuing and (C) the Seller maintains a
short-term rating of at least A-1 by S&P, and for five Business Days following
any reduction, suspension, termination or withdrawal in such rating, or (ii) if
following the occurrence and continuation of any event described in subclause
(i) of this Section 3.2(d), an arrangement is established that is satisfactory
to the Rating Agencies and which does not in itself result in any reduction of
any rating issued in respect of the Senior Certificates, the Servicer may
establish and maintain the Collection Account as a deposit account with the
Seller.

         (e) For all purposes of this Agreement, any amount received at any time
during the term hereof by any Subservicer shall be deemed to constitute receipt
of such amount by the Servicer (receipt by the Servicer shall also be deemed to
occur on the same day as the amount is actually received by the relevant
Subservicer), regardless of whether the Servicer actually receives such amount.

         SECTION 3.3. WITHDRAWALS FROM THE COLLECTION ACCOUNT.

         The Trustee or the Servicer, if the Servicer is then maintaining the
Collection Account pursuant to Section 3.2(d), shall withdraw or cause to be
withdrawn funds from the Collection Account for the following purposes:

                  (i)   two Business Days prior to each Distribution Date, to
         deposit to the Distribution Account (a) the Available Distribution
         Amount for each Loan Group for such Distribution Date (less, with
         respect to the first Distribution Date, $50) and (b) an amount equal to
         the Trustee Fee, in each case to the extent the aggregate of such
         amounts is available from amounts received during the Collection Period
         with respect to the related Collection Period, and not used to
         reimburse the Servicer for a Monthly Advance;

                  (ii)  to reimburse the Servicer for any accrued unpaid
         Servicing Fees and for unreimbursed Monthly Advances and Servicing
         Advances. The Servicer's right to reimbursement under this clause (ii)
         for unpaid Servicing Fees and unreimbursed Servicing Advances shall be
         limited to late collections on the related Mortgage Loan, including
         Liquidation Proceeds, Insurance Proceeds and such other amounts as may
         be collected by the Servicer from the related Mortgagor or otherwise
         relating to the Mortgage Loan in respect of which such reimbursed
         amounts are owed. The Servicer's right to reimbursement under this
         clause (ii) for unreimbursed Monthly Advances shall be limited to
         collections, Liquidation Proceeds and Insurance Proceeds on the related
         Mortgage Loan;

                  (iii) to withdraw any amount received from a Mortgagor that is
         recoverable and sought to be recovered as a voidable preference by a
         trustee in bankruptcy pursuant to the United States Bankruptcy Code in
         accordance with a final, nonappealable order of a court having
         competent jurisdiction;



                                       71
<PAGE>   77

                  (iv)   to pay to the Servicer interest earned in respect of
         Eligible Investments or on funds deposited in the Collection Account;

                  (v)    to withdraw any funds deposited in the Collection
         Account that were not required to be deposited therein (such as
         Servicing Compensation) or were deposited therein in error and to pay
         such funds to the appropriate Person;

                  (vi)   to pay the Servicing Compensation pursuant to Section
         3.9 hereof to the extent not retained or paid pursuant to Section
         3.2(b);

                  (vii)  to reimburse the Servicer for Nonrecoverable Advances;
         and

                  (viii) (a) to pay the unpaid Class Principal Balance of the
         Class R-I Certificate and (b) to clear and terminate the Collection
         Account upon the termination of this Agreement and to pay any amounts
         remaining therein to the Class R Certificateholders.

         SECTION 3.4. MONTHLY ADVANCES; COMPENSATING INTEREST.

         (a) No later than 12:00 noon New York City time on the second Business
Day immediately preceding each Distribution Date, the Servicer shall, from its
own funds, deposit in the Distribution Account in immediately available funds by
wire transfer an amount (a "Monthly Advance") equal to the aggregate of the
Monthly Payment of each Mortgage Loan due during the related Collection Period,
but not received by the Servicer on or before the related Determination Date,
such Monthly Advance to be in an amount net of the Servicing Fee payable with
respect to such Mortgage Loans on the related Distribution Date. Notwithstanding
the foregoing, the Servicer shall not be required to make a Monthly Advance if
in the good faith judgment and sole discretion of the Servicer, the Servicer
determines that such advance would constitute a Nonrecoverable Advance. The
determination by the Servicer that it has made, or would be making, a
Nonrecoverable Advance shall be evidenced by a certificate of a Responsible
Officer of the Servicer delivered to the Trustee and stating the basis for such
determination. The Servicer's obligation to make a Monthly Advance with respect
to any Mortgage Loan will continue until such Mortgage Loan becomes a Liquidated
Mortgage Loan. The Servicer may distribute Payaheads paid to the Servicer not
yet due in lieu of a required advance of scheduled principal and interest, but
must increase its advances in subsequent months for which such Payaheads are due
to cover scheduled payments represented thereby.

         (b) If a Principal Prepayment occurs on any Mortgage Loan during any
Collection Period, the Compensating Interest shall be deposited by the Servicer
to the Collection Account two Business Days prior to the next succeeding
Distribution Date and shall be included in the amount to be made available to
the Trustee on such day.



                                       72
<PAGE>   78

         SECTION 3.5. MAINTENANCE OF HAZARD INSURANCE; PROPERTY PROTECTION
EXPENSES.

         The Servicer shall cause to be maintained for each Mortgage Loan hazard
insurance naming the Servicer as loss payee thereunder providing extended
coverage in an amount which is at least equal to the lesser of (A) the maximum
insurable value of the improvements securing such Mortgage Loan from time to
time, (B) the principal balance owing on such Mortgage Loan or (C) the minimum
amount required to compensate for damage or loss on a replacement cost basis in
each case in an amount not less than such amount as is necessary to avoid the
application of any co-insurance clause contained in the related hazard insurance
policy. The Servicer shall also maintain on property acquired upon foreclosure,
or by deed in lieu of foreclosure, hazard insurance with extended coverage in an
amount which is at least equal to the lesser of (i) the maximum insurable value
from time to time of the improvements which are a part of such property, (ii)
the principal balance owing on such Mortgage Loan or (iii) the minimum amount
required to compensate for damage or loss on a replacement cost basis at the
time of such foreclosure or deed in lieu of foreclosure plus accrued interest
and the good-faith estimate of the Servicer of related Liquidation Expenses to
be incurred in connection therewith. Amounts collected by the Servicer under any
such policies shall be deposited in the Collection Account to the extent
required by Section 3.2. If the Mortgage Property is in an area identified in
the Federal Register by the Flood Emergency Management Agency as having special
flood hazards and flood insurance has been made available, the Servicer will
cause to be maintained a flood insurance policy with a generally acceptable
insurance carrier, in an amount representing coverage not less than the least of
(i) the outstanding principal balance of the Mortgage Loan, (ii) the maximum
insurable value of the improvements securing such Mortgage Loan or (iii) the
maximum amount of insurance which is available under the National Flood
Insurance Act of 1968, as amended, and the Flood Disaster Protection Act of
1973, as amended. The Servicer shall also maintain on REO for the benefit of the
Trust, (x) fire and hazard insurance with extended coverage in an amount which
is at least equal to the replacement cost of the improvements which are a part
of such property, (y) public liability insurance and, (z) to the extent required
and available under the National Flood Insurance Act of 1968, as amended, and
the Flood Disaster Protection Act of 1973, as amended, flood insurance in an
amount as provided above.

         SECTION 3.6. ASSUMPTION AND MODIFICATION AGREEMENTS.

         In any case in which a Mortgaged Property has been or is about to be
conveyed by the Mortgagor, the Servicer shall exercise or refrain from
exercising its right to accelerate the maturity of such Mortgage Loan consistent
with the then current practice of the Servicer and without regard to the
inclusion of such Mortgage Loan in the Trust unless prohibited by law from doing
so. If it elects not to enforce its right to accelerate or if it is prevented
from doing so by applicable law, the Servicer (so long as such action conforms
with the Seller's underwriting standards at the time for new origination) is
authorized to take or enter into an assumption and modification agreement from
or with the Person to whom such Mortgaged Property has been or is about to be
conveyed, pursuant to which such Person becomes liable under the Mortgage and,
to the extent permitted by applicable law, the Mortgagor remains liable thereon;
provided, however, that the Servicer shall not enter into any such assumption or
modification agreement unless the Servicer has determined that the Person to
become liable under the Mortgage Loan has



                                       73
<PAGE>   79

achieved a credit grade under the Seller's then current credit scoring policy of
at least the same (or comparable) level achieved by the original Mortgagor at
the time the Mortgage Loan was originated and provided that the requirements of
Section 3.1(e) are satisfied. The Servicer shall notify the Trustee that any
assumption and modification agreement has been completed by delivering to the
Trustee an Officer's Certificate certifying that such agreement is in compliance
with this Section 3.6 and by forwarding to the Document Custodian the original
copy of such assumption and modification agreement. Any such assumption and
modification agreement shall, for all purposes, be considered a part of the
related Mortgage File to the same extent as all other documents and instruments
constituting a part thereof. No change in the terms of the related Mortgage Loan
may be made by the Servicer in connection with any such assumption to the extent
that such change would not be permitted to be made in respect of the original
Mortgage Loan pursuant to Section 3.1(e). Any fee collected by the Servicer for
entering into any such agreement will be retained by the Servicer as additional
servicing compensation.

         SECTION 3.7. REALIZATION UPON DEFAULTED MORTGAGE LOANS.

         The Servicer shall pursue the liquidation of such of the Mortgage Loans
as come into and continue in default when, in the determination of the Servicer,
no satisfactory arrangements can be made for collection of delinquent payments
pursuant to Section 3.2. Each such liquidation shall be either by sale of such
Mortgage Loan or by foreclosure (or other comparable conversion to ownership of
the Mortgaged Property securing such Mortgage Loan) as determined by the
Servicer, to result in the receipt by the Trust of the maximum recovery on such
Mortgage Loan on a net present value basis (the relevant discounting of
anticipated collections to be performed at the related Loan Rate). The
determination with respect to the maximum recovery on a Mortgage Loan shall be
in accordance with, and consider the factors, costs, fees and expenses described
on Exhibit Q and the Servicer shall have no liability for such determination, or
actions taken pursuant to such determination, made in good faith and absent
gross negligence or willful misfeasance. If the Servicer has actual knowledge or
reasonably believes that any Mortgaged Property is affected by hazardous or
toxic wastes or substances and that the acquisition of such Mortgaged Property
would not be commercially reasonable, then the Servicer will not cause the Trust
to acquire title to such Mortgaged Property in a foreclosure or similar
proceeding. In connection with any foreclosure or other conversion, the 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. The foregoing is subject to the proviso that the Servicer shall not
be required to expend its own funds in connection with any foreclosure or
restoration of any property unless it shall determine that such expenditure will
increase Net Liquidation Proceeds. In connection with any sale of any Mortgage
Loan arranged by the Servicer, the purchase price of such Mortgage Loan payable
to the Trust will be equal to the amount received from such purchaser net of
costs and expenses related to such sale (which fees shall include a disposition
fee payable to the Servicer as compensation for arranging such sale in an amount
not more than $250 for each Mortgage Loan). Such purchase price shall be
deposited into the Collection Account pursuant to Section 3.2 on the day of such
sale. Promptly upon receipt by the Trustee and the Document Custodian of a
written notification signed by a Servicing Officer to the effect that such
purchase price has been so deposited into the Collection Account, the Document
Custodian shall release to the Servicer the Mortgage File for such sold Mortgage
Loan and the 



                                       74
<PAGE>   80

Trustee shall execute and deliver an assignment, prepared by the Servicer and
furnished by it to the Trustee, substantially in the form of Exhibit E.

         The Servicer shall cause to be deposited, no later than five Business
Days after the receipt thereof, in the Collection Account, all revenues received
with respect to the related REO and shall retain, or cause the Trustee to
withdraw therefrom funds necessary for the proper operation, management and
maintenance of the REO and the fees of any managing agent acting on behalf of
the Servicer.

         The disposition of REO shall be carried out by the Servicer for cash at
such price, and upon such terms and conditions, as the Servicer deems to be in
the best interest of the Certificateholders and, as soon as practicable
thereafter, the expenses of such sale shall be paid. The cash proceeds of sale
of the REO shall be promptly deposited in the Collection Account, net of
Foreclosure Profits accrued and unpaid Servicing Fees and unreimbursed Servicing
Advances and Monthly Advances payable to the Servicer in accordance with Section
3.3, for distribution to the Certificateholders in accordance with Section 5.1
hereof.

         In the event that title to any Mortgage Property is acquired in
foreclosure or by deed in lieu of foreclosure, the deed or certificate of sale
shall be issued to the Trustee, or to its nominee (which may be the Servicer) on
behalf of Certificateholders.

         In the event that the Trust acquires any Mortgaged Property as
aforesaid or otherwise in connection with a default or imminent default on a
Mortgage Loan, such Mortgaged Property shall be disposed of by or on behalf of
the Trust within three (3) years after its acquisition by the Trust unless the
Trustee shall have received a Nondisqualification Opinion to the effect that the
holding by the Trust of such Mortgaged Property subsequent to three (3) years
after its acquisition will not result in the imposition of taxes on "prohibited
transactions" of the Trust as defined in Section 860F of the Code or cause the
Trust to fail to qualify as a REMIC at any time that any Certificates are
outstanding. Notwithstanding any other provision of this Agreement, (i) no
Mortgaged Property acquired by the Servicer pursuant to this Section shall be
rented (or allowed to continue to be rented) unless otherwise required by law or
otherwise used for the production of income by or on behalf of the Trust, and
(ii) no construction shall take place on such Mortgaged Property in such a
manner or pursuant to any terms, in either case, that would cause such Mortgaged
Property to fail to qualify as "foreclosure property" within the meaning of
Section 860G(a)(8) of the Code or result in the receipt by the Trust of any "net
income from foreclosure property" which is subject to taxation within the
meaning of Sections 860G(c) and 857(b)(4)(B) of the Code. If a period greater
than three (3) years is permitted under this Agreement and is necessary to sell
any REO, the Servicer shall give appropriate notice to the Trustee and the
Certificateholders and shall report monthly to the Trustee as to the progress
being made in selling such REO.

         The Servicer will provide to the Trustee on each Distribution Date a
report in the form attached as Exhibit O (a "Liquidation Report") with respect
to each Liquidated Mortgage Loan during the related Collection Period.



                                       75
<PAGE>   81

         SECTION 3.8. TRUSTEE TO COOPERATE.

         On or before each Distribution Date, the Servicer will notify the
Trustee of the payment in full of the Loan Balance of any Mortgage Loan during
the preceding Collection Period. Upon any such payment in full, the Servicer is
authorized to execute, pursuant to the authorization contained in Section 3.1,
if the assignments of Mortgage have been recorded as required hereunder, an
instrument of satisfaction regarding the related Mortgage, which instrument of
satisfaction shall be recorded by the Servicer if required by applicable law and
be delivered to the Person entitled thereto. It is understood and agreed that no
expenses incurred in connection with such instrument of satisfaction or transfer
shall be reimbursed from amounts deposited in the Collection Account.

         From time to time and as appropriate for the servicing or foreclosure
of any Mortgage Loan, the Document Custodian shall, or if the Trustee is holding
the Mortgage Files, the Trustee shall, upon request of the Servicer and delivery
to the Document Custodian or the Trustee, as applicable, of a trust receipt, in
the form annexed hereto as Exhibit I, signed by a Servicing Officer, release the
related Mortgage File to the Servicer and the Document Custodian or the Trustee,
as applicable, shall execute such documents, in the forms provided by the
Servicer, as shall be necessary to the prosecution of any such proceedings or
the taking of other servicing actions. Such trust receipt shall obligate the
Servicer to return the Mortgage File to the Trustee or the Document Custodian
appointed by it when the need therefor by the Servicer no longer exists unless
the Mortgage Loan shall be liquidated, in which case, upon receipt of a
certificate of a Servicing Officer similar to that hereinabove specified, the
trust receipt shall be released by the Document Custodian or the Trustee, as
applicable, to the Servicer.

         In order to facilitate the foreclosure of the Mortgage securing any
Mortgage Loan that is in default following recordation of the Assignments of
Mortgage in accordance with the provisions hereof, the Trustee shall, if so
requested in writing by the Servicer, execute an appropriate assignment in the
form provided to the Trustee by the Servicer to assign such Mortgage Loan for
the purpose of collection to the Servicer (any such assignment shall
unambiguously indicate that the assignment is for the purpose of collection
only), and, upon such assignment, such assignee for collection will thereupon
bring all required actions in its own name and otherwise enforce the terms of
the Mortgage Loan and deposit or credit the Net Liquidation Proceeds, exclusive
of Foreclosure Profits, received with respect thereto in the Collection Account,
it being understood that the Trustee shall have no responsibility for
determining the sufficiency of such assignment for its intended purpose. In the
event that all delinquent payments due under any such Mortgage Loan are paid by
the Mortgagor and any other defaults are cured then the assignee for collection
shall promptly reassign such Mortgage Loan to the Trustee and return it to the
place where the related Mortgage File was being maintained.



                                       76
<PAGE>   82

         SECTION 3.9. SERVICING COMPENSATION; PAYMENT OF CERTAIN EXPENSES BY
SERVICER.

         (a) The Servicer shall be entitled to receive the Servicing Fee in
accordance with the terms of this Agreement as compensation for its services in
connection with servicing the Mortgage Loans. Moreover, additional servicing
compensation in the form of late payment charges, Foreclosure Profits or other
receipts not required to be deposited in the Collection Account shall be
retained by the Servicer as additional compensation. The Servicer shall be
required to pay all expenses incurred by it in connection with its activities
hereunder (including payment of all other fees and expenses not expressly stated
hereunder to be for the account of the Certificateholders) and shall not be
entitled to reimbursement therefor except as specifically provided herein.

         (b) The Servicer shall be required to pay all expenses incurred by it
in connection with its activities under this Agreement, including fees and
disbursements of the independent accountants referred to in Section 3.11, taxes
imposed on the Servicer, and all other fees and expenses not expressly stated
hereunder to be for the account of the Certificateholders (including, without
limitation, the cost of obtaining Opinions of Counsel required under this
Agreement, except as otherwise provided herein), and shall not be entitled to
reimbursement therefor except to the extent that such expenses constitute
Liquidation Expenses or as otherwise specifically provided herein.

         SECTION 3.10. ANNUAL STATEMENT AS TO COMPLIANCE.

         The Servicer, at its expense, will deliver to the Trustee, on or before
the last day of the fifth calendar month of each year, beginning in 1999, an
Officer's Certificate stating that (i) a review of the activities of the
Servicer during the preceding calendar year (or such shorter period as is
applicable in the case of the first report) and of its performance 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 Servicer has fulfilled all
its material 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, the nature and status thereof and the steps
being taken to remedy such default. In addition, the Servicer, at its expense,
will deliver to the Trustee, on or before June 30, 1999, an Officer's
Certificate stating that it is in compliance with Section 2.4(x).

         SECTION 3.11. ANNUAL SERVICING REPORT.

         Not later than the last day of the fifth month following the end of the
Servicer's fiscal year (December 31), beginning in 1999, the Servicer, at its
expense, shall cause a firm of independent public accountants reasonably
acceptable to the Depositor to furnish a letter or letters to the Depositor and
the Trustee to the effect that such firm has with respect to the Servicer's
overall servicing operations examined such operations in accordance with the
requirements of the Uniform Single Attestation Program for Mortgage Bankers, and
stating such firm's conclusions relating thereto.



                                       77
<PAGE>   83

         SECTION 3.12. ACCESS TO CERTAIN DOCUMENTATION AND INFORMATION REGARDING
THE MORTGAGE LOANS.

         (a) The Servicer and the Document Custodian shall provide to the
Trustee, and, to the extent that any Certificateholder is a federally insured
savings association, the Office of Thrift Supervision, successor to the Federal
Home Loan Bank Board, to the FDIC and the supervisory agents and examiners of
the Office of Thrift Supervision, reasonable access to the documentation
regarding the Mortgage Loans, and the right to inspect the Servicer's servicing
operations and discuss such operations, such access being afforded without
charge but only upon reasonable notice and reasonable in scope and during normal
business hours at their respective offices. Nothing in this Section 3.12 shall
derogate from the obligation of the Servicer to observe any applicable law
prohibiting disclosure of information regarding the Mortgagors and the failure
of the Servicer to provide access as provided in this Section 3.12 as a result
of such obligation shall not constitute a breach of this Section 3.12.

         (b) The Servicer shall supply information to the Trustee and the Paying
Agent in such form as the Trustee shall reasonably request, on or before the
start of the fifth Business Day preceding the related Distribution Date, as is
required in the Trustee's reasonable judgment to enable the Paying Agent or the
Trustee, as the case may be, to make required distributions and to furnish the
required reports to Certificateholders.

         SECTION 3.13. MAINTENANCE OF CERTAIN INSURANCE POLICIES.

         (a) The Servicer shall during the term of its service as servicer
maintain in force (i) a policy or policies of insurance covering errors and
omissions in the performance of its obligations as Servicer hereunder and (ii) a
fidelity bond in respect of its officers, employees or agents. Each such policy
or policies and bond shall, together, comply with the requirements from time to
time of Fannie Mae for persons performing servicing for mortgage loans purchased
by Fannie Mae. Any such fidelity bond and errors and omissions insurance shall
protect and insure the Servicer against losses, including losses resulting from
forgery, theft, embezzlement, fraud, errors and omissions and negligent acts of
Servicer employees. Such fidelity bond shall also protect and insure the
Servicer against losses in connection with the release or satisfaction of a
Mortgage Loan without having obtained payment in full of the indebtedness
secured thereby. No provision of this Section 3.13 requiring such fidelity bond
and errors and omissions insurance shall diminish or relieve the Servicer from
its duties and obligations as set forth in this Agreement. Upon the request of
the Trustee or any Certificateholder, the Servicer shall cause to be delivered
to the Trustee or such Certificateholder a certified true copy of such fidelity
bond and insurance policy.

         (b) In the event that the Servicer shall obtain and maintain a blanket
policy consistent with prudent industry standards insuring against fire and
hazards of extended coverage on all of the Mortgage Loans, then, to the extent
such policy names the Servicer as loss payee and provides coverage in an amount
equal to the aggregate unpaid principal balance on the Mortgage Loans without
co-insurance, and otherwise complies with the requirements of Section 3.5, the
Servicer shall be deemed conclusively to have satisfied its obligations with
respect to fire and hazard (including flood) insurance coverage under Section
3.5, it being understood and agreed 



                                       78
<PAGE>   84

that such blanket policy may contain a deductible clause, in which case the
Servicer shall, in the event that there shall not have been maintained on the
related Mortgaged Property a policy complying with Section 3.5, and there shall
have been a loss which would have been covered by such policy, deposit in the
Collection Account the difference, if any, between the amount that would have
been payable under a policy complying with Section 3.5 and the amount paid under
such blanket policy. Upon the request of the Trustee or any Certificateholder,
the Servicer shall cause to be delivered to the Trustee or such
Certificateholder, as the case may be, a certified true copy of such policy. In
connection with its activities as administrator and servicer of the Mortgage
Loans, the Servicer agrees to prepare and present, on behalf of itself, the
Trustee, and Certificateholders, claims under any such policy in a timely
fashion in accordance with the terms of such policy.

         SECTION 3.14. REPORTS OF FORECLOSURES AND ABANDONMENTS OF MORTGAGED
PROPERTY, RETURNS RELATING TO MORTGAGE INTEREST RECEIVED FROM INDIVIDUALS AND
RETURNS RELATING TO CANCELLATION OF INDEBTEDNESS.

         The Servicer shall make reports of foreclosures and abandonments of any
Mortgaged Property for each calendar year beginning in 1998. The Servicer shall
file reports relating to each instance occurring during the previous calendar
year in which the Servicer (i) on behalf of the Trustee acquires an interest in
any Mortgaged Property through foreclosure or other comparable conversion in
full or partial satisfaction of a Mortgage Loan, or (ii) knows or has reason to
know that any Mortgaged Property has been abandoned. The reports from the
Servicer shall be in form and substance sufficient to meet the reporting
requirements imposed by Sections 6050J, 6050H and 6050P of the Code.

         SECTION 3.15. REPORTS TO THE SECURITIES AND EXCHANGE COMMISSION.

         The Trustee shall, on behalf of the Trust, cause to be filed with the
Securities and Exchange Commission any periodic reports required to be filed
under the provisions of the Securities Exchange Act of 1934, as amended, and the
rules and regulations of the Securities and Exchange Commission thereunder. Upon
the request of the Trustee, each of the Seller, the Servicer and the Depositor
shall cooperate with the Trustee in the preparation of any such report and shall
provide to the Trustee in a timely manner all such information or documentation
as the Trustee may reasonably request in connection with the performance of its
duties and obligations under this Section.

         SECTION 3.16. CUSTODY OF MORTGAGE FILES.

         The Trustee hereby agrees to act as Document Custodian of the Related
Documents for each Mortgage Loan. From time to time following delivery of the
Mortgage Files and the Related Documents to the Trustee pursuant to Section
2.01(a) hereof, the Trustee may engage the services of another Person (other
than the Depositor or an Affiliate of the Depositor) who is acceptable to the
Depositor, the Seller and the Servicer with the consent of the Rating Agencies,
to act as Document Custodian. Upon execution of a custodial agreement consistent
with the terms hereof, such Document Custodian shall maintain possession of the
Mortgage Files, or such part of them as the Trustee shall direct, as agent of
the Trustee pursuant to the terms of such 



                                       79
<PAGE>   85

custodial agreement. The Seller shall be required to pay the Trustee (or any
other Person designated by the Trustee to act as document custodian) reasonable
fees based on the reciprocal fees charged by the Trustee and the Seller for
similar services. The Document Custodian (if other than the Trustee) shall
acknowledge that it is bailee for the Trustee and is holding all of Related
Documents delivered to it in trust for the Trustee. The Trustee shall not be
liable to any Person for actions or failures to take action of the Document
Custodian, unless, and only to the extent, such actions or failures to act
constitute willful misconduct or negligence.

         While the Mortgage Files and the Related Documents are required to be
in the possession of the Trustee or a Document Custodian appointed by it, the
Trustee shall keep the Servicer apprised at all times of the location of the
Mortgage Files.

         SECTION 3.17. DUTIES OF DOCUMENT CUSTODIAN; AUTHORITY; INDEMNIFICATION.

         (a) Safekeeping. The Document Custodian shall hold the Mortgage Files
for the benefit of the Trustee and maintain such accurate and complete accounts,
records and computer systems pertaining to each Mortgage File as shall enable
the Depositor, the Seller, the Servicer and the Trustee to comply with this
Agreement. The Document Custodian shall act with reasonable care, using that
degree of skill and attention in the performance of its duties as it exercises
with respect to the mortgage files relating to all comparable mortgage loans
that it owns or services for itself or others. The Document Custodian shall
conduct, or cause to be conducted, periodic audits of the Mortgage Files held by
it under this Agreement and of the related accounts, records and computer
systems, in such a manner as shall enable the Trustee to verify the accuracy of
the Servicer's record keeping. The Document Custodian shall promptly report to
the Trustee and the Servicer any failure on its part to hold the Mortgage Files
and maintain its accounts, records and computer systems as herein provided and
promptly take appropriate action to remedy any such failure.

         (b) Maintenance of and Access to Records. The Document Custodian shall
maintain each Mortgage File at one of its offices specified in Schedule 1 or at
such other office as shall be specified to the Trustee by written notice
immediately upon any change in location. The Document Custodian (if other than
the Trustee) shall make available to the Trustee or its duly authorized
representatives, attorneys or auditors a list of locations of the Mortgage Files
and the related accounts, records and computer systems maintained by the
Document Custodian at such times during normal business hours as the Trustee
shall instruct.

         (c) Release of Documents. Upon written instruction in the form of
Exhibit I from the Trustee (if other than the Document Custodian), the Servicer
or a Subservicer, the Document Custodian shall release any Mortgage File to the
Trustee, the Trustee's agent, the Trustee's designee, the Servicer or a
Subservicer requested in such written instruction, as the case may be, at such
place or places as requested in such written instruction, as soon as
practicable. The Document Custodian shall provide written notice to the Servicer
monthly of any such release to a Subservicer.

         (d) Review of Documents. The Document Custodian shall perform the
review (described in Section 2.1(c)) of each Related Document in each Mortgage
File within 180 days 



                                       80
<PAGE>   86

from (i) the Closing Date (or the date of actual receipt of such document if not
received on the Closing Date), with respect to each Mortgage Loan transferred to
the Trust on the Closing Date, (ii) the Subsequent Transfer Date, with respect
to each Subsequent Mortgage Loan transferred to the Trust on a Subsequent
Transfer Date and (iii) the Transfer Date, with respect to each Eligible
Substitute Mortgage Loan transferred to the Trust. Upon completion of such
180-day period, the Document Custodian will notify the Trustee (if the Trustee
is not also the Document Custodian) and the Servicer of any material defect
discovered in such review and the Trustee shall notify the Depositor of such
material defect, as provided in Section 2.1(c) and on each annual anniversary of
the Closing Date shall provide the Trustee, the Servicer and the Depositor a
report updating the status of such defects.

         (e) Instructions; Authority To Act. The Document Custodian (if other
than the Trustee) shall be deemed to have received proper instructions with
respect to the Mortgage Files upon its receipt of written instructions signed by
a Responsible Officer of the Trustee.

         (f) Document Custodian's Indemnification. The Document Custodian shall
indemnify the Seller, the Servicer, the Depositor, the Trust, and the Trustee
(if the Trustee is not also the Document Custodian), and each of their officers,
directors and agents for any and all liabilities, obligations, losses,
compensatory damages, payments, costs or expenses of any kind whatsoever that
may be imposed on, incurred by or asserted against any such person or any of
their officers, directors and agents as the result of any improper act or
omission in any way relating to the maintenance and custody by the Document
Custodian as custodian of the Mortgage Files; provided, however, that the
Document Custodian shall not be liable to any such Person for any amount and any
portion of any such amount resulting from the willful misfeasance, bad faith or
negligence of such Person. The provisions of this Section 3.17(f) shall survive
the termination of this Agreement.

         (g) Location of Mortgage Loans. The Mortgage Loans and Related
Documents shall not be located outside the State of Minnesota unless the
Document Custodian shall deliver an Opinion of Counsel to the Trustee to the
effect that all actions have been taken, including the filing of UCC financing
statements, to perfect the rights of the Trustee in the Mortgage Loans and
Related Documents.

         SECTION 3.18. [RESERVED]

         SECTION 3.19. PAYMENT OF TAXES, INSURANCE AND OTHER CHARGES.

         With respect to each Mortgage Loan, the Servicer shall maintain
accurate records reflecting fire and hazard (including flood) insurance
coverage.

         With respect to each Mortgage Loan as to which the Servicer maintains
escrow accounts, the Servicer shall maintain accurate records reflecting the
status of ground rents, taxes, assessments, water rates and other charges which
are or may become a lien upon the Mortgaged Property and the status of primary
mortgage guaranty insurance premiums, if any, and fire and hazard insurance
coverage and shall obtain, from time to time, all bills for the payment of such
charges (including renewal premiums) and shall effect payment thereof prior to
the applicable 



                                       81
<PAGE>   87

penalty or termination date and at a time appropriate for securing maximum
discounts allowable, employing for such purpose deposits of the Mortgagor in any
escrow account which shall have been estimated and accumulated by the Servicer
in amounts sufficient for such purposes, as allowed under the terms of the
Mortgage. To the extent that a Mortgage does not provide for escrow payments,
the Servicer shall, if it has received notice of a default or deficiency,
monitor such payments to determine if they are made by the Mortgagor.

         SECTION 3.20. ALLOCATION OF REALIZED LOSSES.

         Prior to each Distribution Date, the Servicer shall determine the
amount of Realized Losses, if any, with respect to each Mortgage Loan. The
amount of Realized Losses shall be evidenced by an Officer's Certificate signed
by a Responsible Officer of the Servicer. All Realized Losses, except for
Special Hazard Losses, Fraud Losses and Bankruptcy Losses in excess of the
designated amounts of the applicable Special Hazard Coverage, Fraud Coverage and
Bankruptcy Coverage (each, as defined herein), will be allocated by the Trustee
as follows: (i) for losses allocable to principal (a) first, to the Class B-5
Certificates, until the Class Principal Balance thereof has been reduced to
zero, (b) second, to the Class B-4 Certificates, until the Class Principal
Balance thereof has been reduced to zero, (c) third, to the Class B-3
Certificates, until the Class Principal Balance thereof has been reduced to
zero, (d) fourth, to the Class B-2 Certificates, until the Class Principal
Balance thereof has been reduced to zero, (e) fifth, to the Class B-1
Certificates, until the Class Principal Balance thereof has been reduced to
zero, (f) sixth, to the Class M Certificates, until the Class Principal Balance
thereof has been reduced to zero, and (g) seventh, to the Senior Certificates
related to such Mortgage Loan (other than the Class SA-5 Certificates, Class
SA-X Certificates, Class A-6 Certificates, the Class A-X Certificates), pro
rata, according to their Class Principal Balances in reduction of their
respective Class Principal Balances, as applicable; and (ii) for losses
allocable to interest (a) first, to the Class B-5 Certificates, in reduction of
accrued but unpaid interest thereon and then in reduction of the Class Principal
Balance of such Certificates, (b) second, to the Class B-4 Certificates, in
reduction of accrued but unpaid interest thereon and then in reduction of the
Class Principal Balance of such Certificates, (c) third, to the Class B-3
Certificates, in reduction of accrued but unpaid interest thereon and then in
reduction of the Class Principal Balance of such Certificates, (d) fourth, to
the Class B-2 Certificates, in reduction of accrued but unpaid interest thereon
and then in reduction of the Class Principal Balance of such Certificates, (e)
fifth, to the Class B-1 Certificates, in reduction of accrued but unpaid
interest thereon and then in reduction of the Class Principal Balance of such
Certificates, (f) sixth, to the Class M Certificates, in reduction of accrued
but unpaid interest thereon and then in reduction of the Class Principal Balance
of such Certificates, and (g) seventh, to the applicable Senior Certificates
related to such Mortgage Loan, pro rata according to accrued but unpaid interest
thereon and then pro rata according to their Class Principal Balances in
reduction of their respective Class Principal Balances, as applicable.

         Special Hazard Losses in excess of the Special Hazard Coverage, Fraud
Losses in excess of the Fraud Coverage and Bankruptcy Losses in excess of the
Bankruptcy Coverage shall be allocated among the related Senior Certificates and
the Subordinate Certificates by Pro Rata Allocation.



                                       82
<PAGE>   88

         On each Distribution Date, after giving effect to the principal
distributions and allocations of losses as provided in this Agreement (without
regard to this paragraph), if the Aggregate Class Principal Balance of all
outstanding Classes of Certificates exceeds the Aggregate Loan Balance, then
such excess will be deemed a principal loss and will be allocated to the most
junior Class of Subordinate Certificates then outstanding, in reduction of the
Certificate Principal Balance thereof.


                                   ARTICLE IV

                 SERVICING CERTIFICATE; PRE-FUNDING ACCOUNT AND
                          CAPITALIZED INTEREST ACCOUNT;

         SECTION 4.1. SERVICING CERTIFICATE.

         Not later than the fifth Business Day of each month, the Servicer shall
deliver to the Trustee a Servicing Certificate (substantially in the form of
Exhibit H or the form of computer readable media or such other electronic form
as may be agreed to by the Trustee and the Servicer) (which Servicing
Certificate shall be deemed to constitute a certification that the information
contained in such Servicing Certificate is true and correct in all material
respects), stating the related Collection Period, Distribution Date, the series
number of the Certificates, the date of this Agreement, and:

                  (i)   the aggregate amount of collections received on the
         Mortgage Loans on or prior to the Determination Date in respect of such
         Collection Period, separately stating the amounts received in respect
         of principal and interest;

                  (ii)  the aggregate amount of (a) Interest Collections and (b)
         Principal Collections for such Collection Period; and

                  (iii) any other information regarding the Mortgage Loans
         necessary for the Trustee to make distributions and payments in
         accordance with Section 5.1 and to prepare the reports required to be
         delivered to Certificateholders pursuant to Section 5.2 and the notice
         to the Servicer pursuant to Section 3.4(b).

         The Trustee shall conclusively rely upon the information contained in a
Servicing Certificate for purposes of making distributions pursuant to Section
5.1 and for all other purposes, shall have no duty to inquire into such
information and shall have no liability in so relying. The format and content of
the Servicing Certificate may be modified by the mutual agreement of the
Servicer and the Trustee.

         SECTION 4.2. PRE-FUNDING ACCOUNT AND CAPITALIZED INTEREST ACCOUNT.

         (a) The Trustee has heretofore established or caused to be established
and shall hereafter maintain or cause to be maintained a separate account
denominated a Pre-Funding



                                       83
<PAGE>   89

Account, which in each case is and shall continue to be an Eligible Account in
the name of the Trustee and shall be designated "Norwest Bank Minnesota,
National Association as Trustee, in trust for the registered holders of FURST
Mortgage Pass-Through Certificates, Series 1998-A Pre-Funding Account." The
Pre-Funding Account will not be an asset of any of the REMICs. Any investment
earnings on the Pre-Funding Account will be treated as owned by the Depositor
and will be taxable to the Depositor. The Trustee has heretofore established or
caused to be established and shall hereafter maintain or cause to be maintained
a separate account denominated a Capitalized Interest Account, which in each
case is and shall continue to be an Eligible Account in the name of the Trustee
and shall be designated "Norwest Bank Minnesota, National Association as
Trustee, in trust for the registered holders of FURST Mortgage Pass-Through
Certificates, Series 1998-A Capitalized Interest Account." The Capitalized
Interest Account shall be treated as an "outside reserve fund" under applicable
Treasury regulations and will not be an asset of any of the REMICs. Any
investment earnings on the Capitalized Interest Account will be treated as owned
by the Depositor and will be taxable to the Depositor. The amount on deposit in
the Pre-Funding Account and the Capitalized Interest Account shall be invested
in Eligible Investments in accordance with the provisions of Section 5.4. For
all Federal tax purposes, amounts, if any, transferred by any REMIC to the
Capitalized Interest Account will be treated as amounts distributed by such
REMIC to the Depositor.

         (b) On the Closing Date, the Seller, on behalf of the Depositor, will
cause to be deposited in the Pre-Funding Account the Original Pre-Funded Amount
and shall deposit in the Capitalized Interest Account the amount of
$1,065,360.92.

         (c) On any Subsequent Transfer Date, upon satisfaction of the
conditions set forth in Section 2.10(b), the Trustee shall contribute to the
REMIC I from the Pre-Funding Account an amount equal to 100% of the aggregate
Cut-Off Date Loan Balances of the Subsequent Mortgage Loans transferred to the
Trust on such Subsequent Transfer Date, as indicated on the related Addition
Notice furnished to the Trustee pursuant to Section 2.10(b)(i), and pay such
amount on behalf of the REMIC I and on behalf of the Depositor to or upon the
order of the Seller upon satisfaction of such conditions set forth in Section
2.10 hereof with respect to such transfer. The Trustee shall maintain an
accurate ledger that shall indicate at any time the amount on deposit in the
Pre-Funding Account, the amount of Pre-Funding Account Earnings and withdrawals
of such amounts.

         (d) (i)  If the Pre-Funded Amount has not been reduced to zero by July
24, 1998, the Trustee shall withdraw from the Pre-Funding Account such amount on
deposit in the Pre-Funding Account on the Business Day preceding the
Distribution Date in July, 1998 (after giving effect to all withdrawals from the
Pre-Funding Account on such date) and contribute such amount to the REMIC I as
part of the Available Distribution Amount for distribution to the Holders of the
Class or Classes of Class A and Subordinate Certificates entitled to receive
principal distributions on the Distribution Date in July, 1998;

             (ii) if the Pre-Funded Amount is reduced to less than or equal to
         $100,000 as of either of the first two Determination Dates, the Trustee
         shall withdraw from the Pre-Funding Account the amount remaining on
         deposit in the Pre-Funding Account on such



                                       84
<PAGE>   90

         Determination Date (after giving effect to all withdrawals from the
         Pre-Funding Account on such date) and contribute such amount to REMIC I
         for distribution to the Holders of the Class or Classes of Class A and
         Subordinate Certificates entitled to receive principal distributions on
         the next Distribution Date.

         The amount contributed to the REMIC I pursuant to either paragraph (i)
or (ii) of this subsection shall be net of any Pre-Funding Account Earnings,
except in the case of clause (e) below.

         (e) On the first, second and third Distribution Date during the Funding
Period the Trustee shall contribute to REMIC I from the Pre-Funding Account, the
Pre-Funding Account Earnings, if any, applicable to such Distribution Date.
Pre-Funding Account Earnings on each such Distribution Date shall be included in
the Available Distribution Amount for such Distribution Date for distribution
with respect to the Class A and Subordinate Certificates only.

         (f) On the Business Day prior to each of the first, second and third
Distribution Dates the Trustee shall contribute to the REMIC I from the
Capitalized Interest Account, the Capitalized Interest Requirement, if any, for
such Distribution Date. The Capitalized Interest Requirement for each such
Distribution Date shall be included in the Available Distribution Amount on such
Distribution Date for distribution with respect to the Class A and Subordinate
Certificates only.

         (g) On each Subsequent Transfer Date, the Trustee, on behalf of the
Depositor, shall distribute the Overfunded Interest Amount (calculated by the
Trustee on the Business Day prior to such Subsequent Transfer Date), if any, to
the Seller, and on the last day of the Funding Period or, if such date is not a
Distribution Date, the next succeeding Distribution Date, the Trustee, on behalf
of the Depositor, shall distribute to the Seller any amounts remaining in the
Capitalized Interest Account (including any earnings thereon) after taking into
account withdrawals from the Capitalized Interest Account on such Distribution
Date. The Capitalized Interest Account shall be closed after the third
Distribution Date. All amounts, if any, remaining in the Capitalized Interest
Account on such day shall be transferred, on behalf of the Depositor, to the
Seller.

         (h) The Trustee has heretofore established or caused to be established
and shall hereafter maintain or cause to be maintained a separate account
denominated a Class A-7 Reserve Fund, which is and shall continue to be an
Eligible Account in the name of the Trustee and shall be designated "Norwest
Bank Minnesota, National Association as Trustee, in trust for the registered
holders of FURST Mortgage Pass-Through Certificates, Series 1998-A Class A-7
Reserve Fund". Amounts on deposit in the Class A-7 Reserve Fund will not be
invested. On the Business Day prior to each of the first twelve Distribution
Dates, the Trustee shall withdraw from the Class A-7 Reserve Fund and deposit
into the Distribution Account an amount equal to the Class A-7 Interest Reserve
Amount.

         SECTION 5.1.          DISTRIBUTIONS.

         (a) With respect to the Distribution Account, on each Distribution
Date, the Trustee shall make the following disbursements from amounts
transferred thereto pursuant to Sections 3.3(ii), 4.2(e), 4.2(f) and 4.2(h), in
the following order of priority, and each such disbursement shall be treated as
having occurred only after all preceding disbursements have occurred:

             (i)  First, to the Trustee, the Trustee Fee;

            (ii) Second, to each Certificateholder, from the amount and to the
extent of the Available Distribution Amount for each Loan Group, such
Certificateholder's share (based on the aggregate Percentage Interests
represented by the Certificates of the applicable Class held by such
Certificateholder) of the amounts and in the order of priority as set forth in
the definition of "Certificate Distribution Amount", by wire transfer in
immediately available funds for the account of each Certificateholder, or by any
other means of payment acceptable to each Certificateholder of record on the
immediately preceding Record Date (other than as provided in Section 10.1
respecting the final distribution), as specified by each such Certificateholder
and at the address of such Holder appearing in the Certificate Register.

         (b) All reductions in the Certificate Principal Balance of a
Certificate effected by distributions of principal or allocations of Realized
Losses with respect to Mortgage Loans made on any Distribution Date shall be
binding upon all Holders of such Certificate and of any Certificate issued upon
the registration of transfer or exchange therefor or in lieu thereof, whether or
not such distribution is noted on such Certificate. The final distribution of
principal of each Certificate (and the final distribution with respect to the
Class R Certificate upon termination of the Trust) shall be payable in the
manner provided above only upon presentation and surrender thereof on or after
the Distribution Date therefor at the office or agency of the Trustee specified
in the notice delivered pursuant to Section 5.1(c) or Section 10.1.

         (c) Whenever, on the basis of Curtailments, Payoffs and Monthly
Payments on the Mortgage Loans and Insurance Proceeds and Liquidation Proceeds
received and expected to be received during the applicable Collection Period,
the Trustee believes, that the entire remaining unpaid Class Principal Balance
of any Class of Certificates will become distributable on the next Distribution
Date, the Trustee, shall, no later than the Determination Date of the month of
such Distribution Date, mail or cause to be mailed to each Person in whose name
a Certificate to be so retired is registered at the close of business on the
Record Date, to the Underwriters and to each Rating Agency a notice to the
effect that:



                                       86
<PAGE>   92



                  (i)  it is expected that funds sufficient to make such final
         distribution will be available in the Collection Account on such
         Distribution Date, and

                  (ii) if such funds are available, (A) such final distribution
         will be payable on such Distribution Date, but only upon presentation
         and surrender of such Certificate at the office or agency of the
         Certificate Registrar maintained for such purpose (the address of which
         shall be set forth in such notice), and (B) no interest shall accrue on
         such Certificate after such Distribution Date.

         (d) Method of Distribution. The Trustee shall make distributions in
respect of a Distribution Date to each Certificateholder of record on the
related Record Date (other than as provided in Section 10.1 respecting the final
distribution) by check or money order mailed to such Certificateholder at the
address appearing in the Certificate Register, or upon written request by a
Certificateholder delivered to the Trustee at least five Business Days prior to
such Record Date, by wire transfer (but only if such Certificateholder is the
Depositor or such Certificateholder owns of record either (a) one or more
Certificates of a Class aggregating at least $1,000,000 Original Class
Certificate Principal Balance or (b) one or more Class Certificates of a Class
with Percentage Interests aggregating 30%). Distributions among
Certificateholders shall be made in proportion to the Percentage Interests
evidenced by the Certificates held by such Certificateholders.

         (e) Distributions on Book-Entry Certificates. Each distribution with
respect to a Book-Entry Certificate shall be paid to the Depository, which shall
credit the amount of such distribution to the accounts of its Depository
Participants in accordance with its normal procedures. Each Depository
Participant shall be responsible for disbursing such distribution to the
Certificate Owners that it represents and to each indirect participating
brokerage firm (a "brokerage firm" or "indirect participating firm") for which
it acts as agent. Each brokerage firm shall be responsible for disbursing funds
to the Certificate Owners that it represents. All such credits and disbursements
with respect to a Book-Entry Certificate are to be made by the Depository and
the Depository Participants in accordance with the provisions of the
Certificates. None of the Trustee, the Paying Agent, the Trustee, the Depositor,
the Servicer or the Seller shall have any responsibility therefor except as
otherwise provided by applicable law.

         SECTION 5.2.      STATEMENTS.

         (a) Not later than 12:00 a.m. New York time on each Distribution Date,
the Trustee shall deliver to the Servicer, the Depositor and the Seller by

         (a) Consistent with any requirements of the Code, all or a portion of
the Distribution Account, the Pre-Funding Account and the Capitalized Interest
Account held by the Trustee shall be invested and reinvested by the Trustee, in
one or more Eligible Investments bearing interest or sold at a discount. Any
investment earnings on funds held in the Distribution Account shall be for the
account of the Servicer. No such investment in such accounts shall mature later

that (i) if such Eligible Investment is an obligation of or is advised by the
Trustee or an affiliate of the Trustee, then such Eligible Investment shall
mature not later than such Distribution Date and (ii) any other date as may be

         (b) If any amounts are needed for disbursement from any Account held by
the Trustee and sufficient uninvested funds are not available to make such
disbursements, the Trustee shall cause to be sold or otherwise converted to cash
a sufficient amount of the investments in such Account.

         (c) The Servicer shall deposit in the Distribution Account from its own
funds the amount of any loss incurred in respect of any Eligible Investment held

the Trustee shall bind the Trust, notwithstanding that such individuals or any
of them have ceased to be so authorized prior to the authentication 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 such Certificate shall have been
manually authenticated by the Trustee substantially in the form provided for
herein, and such authentication upon any Certificate shall be conclusive
evidence, and the only evidence, that such Certificate has been duly
authenticated and delivered hereunder. All Certificates shall be dated the date
of their authentication. Subject to Section 6.2(b)(ii), the Class SA
Certificates the Class A Certificates, the Class M Certificates, the Class B-1

reasonable regulations as it may prescribe, the Certificate Registrar shall
provide for the registration of the Certificates and of Transfers of the
Certificates as herein provided. The Trustee shall initially serve as

Certificate Registrar shall have any liability for transfers of Book-Entry
Certificates made through the book-entry facilities of DTC or between or among
any Depository Participants or Certificate Owners, made in violation of
applicable restrictions.

         Upon surrender for registration of Transfer of any Certificate (other

(ii) below) at any office or agency of the Certificate Registrar maintained for
such purpose pursuant to the foregoing paragraph and, in the case of the Class M
Certificates, the Class B Certificates and Residual Certificates upon the
satisfaction of those conditions applicable to such Certificates, as set forth
in Sections 6.2(b) and (c) hereof, the Trustee shall execute, authenticate and
deliver, in the name of the designated transferee or transferees, one or more
new Certificates of a like Class and of the same aggregate Percentage Interest.

         At the option of the Certificateholders, Certificates (other than
Book-Entry Certificates which shall be subject to Section 6.2(b)(i) and (ii)
below) may be exchanged for other Certificates in authorized denominations and
the same aggregate Percentage Interests, upon surrender of the Certificates to
be exchanged at any such office or agency. Whenever any Certificates are so
surrendered for exchange, the Trustee shall execute, authenticate and deliver
the Certificates of such Class which the Certificateholder making the exchange
is entitled to receive. Every Certificate presented or surrendered for
registration of Transfer or exchange shall (if so required by the Trustee or the
Certificate Registrar) be duly endorsed by, or be accompanied by a written
instrument of transfer in form satisfactory to the Trustee and the Certificate
Registrar duly executed by, the Holder thereof or its attorney duly authorized
in writing.

of a sum sufficient to cover any tax or governmental charge that may be imposed
in connection with any transfer or exchange of Certificates.

         All Certificates surrendered for registration of Transfer shall be
canceled by the Certificate Registrar and disposed of pursuant to its standard
procedures.

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; (vii) the Depository shall be responsible
for crediting the amount of distributions to the accounts of the Certificate
Owners entitled thereto, in accordance with the Depository's normal procedures;
(viii) unless and until Definitive Certificates are issued pursuant to Section
6.2(b)(ii) below, the Depository will make book-entry transfers among the
Depository Participants and receive and transmit distributions of principal of

(ix) whenever notice or other communication to the Certificate Owners is
required under this Agreement, unless and until Definitive Certificates shall
have been issued to Certificate Owners pursuant to Section 6.2(b)(ii) below, the
Trustee shall give all such notices and communications specified herein to be
given to such Certificate Owners to the Depository.

                  All transfers by Certificate Owners of Book-Entry Certificates

Participant or brokerage firm representing such Certificate Owners. Each
Depository Participant shall only transfer Book-Entry Certificates of

hereto are hereby authorized to execute a Depositary Agreement with the
Depository or take such other action as may be necessary or desirable to
register a Book-Entry Certificate to Depository. In the event of any conflict
between the terms of any such Depositary Agreement and this Agreement the terms
of this Agreement shall control.

                  (ii) If (i)(x) the Depository or the Depositor advises the
Trustee in writing that the Depository is no longer willing or able to discharge
properly its responsibilities as Depository, and (y) the Trustee or the
Depositor is unable to locate a qualified successor, (ii) the Depositor, at its
sole option, with consent of the Trustee, elects to terminate the book-entry
system through the Depository or (iii) after the occurrence of an Event of

representing Percentage Interests aggregating not less than 51% advises the
Trustee and Depository through the Depository Participants in writing that the
continuation of a book-entry system through the Depository to the exclusion of
definitive, fully registered certificates (the "Definitive Certificates") to
Certificate Owners is no longer in the best interests of the Certificate Owners.
Upon surrender to the Trustee of each 



                                       94
<PAGE>   100

Class of Book-Entry Certificates by the Depository, accompanied by registration
instructions from the Depository for registration, the Trustee shall, at the
Depositor's expense, in the case of (i) and (ii) above, or the Seller's expense,
in the case of (iii) above, execute and authenticate the Definitive
Certificates. Neither the Depositor nor the Trustee shall be liable for any
delay in delivery of such instructions and may conclusively rely on, and shall
be protected in relying on, such instructions. Upon the issuance of Definitive
Certificates, the Trustee, the Servicer, any Paying Agent and the Depositor
shall recognize the Holders of the Definitive Certificates as Certificateholders
hereunder.

                  (iii) No Transfer of a Class B-3 Certificate, Class B-4
Certificate, or Class B-5 Certificate shall be made or registered unless such
Transfer is exempt from the registration requirements of the Securities Act and
any applicable state securities laws or is made in accordance with the
Securities Act and laws. In the event that such a Transfer of a Class B-3
Certificate, Class B-4 Certificate, or Class B-5 Certificate is to be made, the
Trustee may require (A) a certificate from the Certificateholder desiring to
effect such transfer substantially in the form attached hereto as Exhibit L-1
and a certificate from such Certificateholder's prospective transferee
substantially in the form attached hereto either as Exhibit L-2A or as Exhibit
L-2B; or (B) a written Opinion of Counsel substantially in the form of Exhibit
L-3 or otherwise acceptable to the Trustee to the effect that such Transfer may
be made pursuant to an exemption, describing the applicable exemption and the
basis therefor, from the Securities Act and laws or is being made pursuant to
such Act and laws. The Holder of a Class B-3 Certificate, Class B-4 Certificate,
or Class B-5 Certificate desiring to effect such Transfer shall, and does hereby
agree to, indemnify the Trustee and the 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 Opinion of Counsel delivered pursuant to this subsection 6.2(b)(iii)
shall be an expense of the Trustee or the Servicer, but shall, in each case, be
paid either by the Holder of the Class B-3 Certificate, Class B-4 Certificate,
or Class B-5 Certificate subject to the proposed Transfer or by the proposed
transferee.

         (c) No Transfer of a Class M Certificate in the form of a Definitive
Certificate, a Class B Certificate in the form of a Definitive Certificate or
Residual Certificate shall be made or registered unless the Trustee shall have
received either (i) a representation letter in the form of Exhibit J from the

employee benefit plan subject to the Employee Retirement Income Security Act of
1974, as amended ("ERISA"), and to Section 4975 of the Code (or comparable
provisions of any subsequent enactments), or a trustee of any such plan, an
Opinion of Counsel in form and substance satisfactory to the Trustee to the
effect that the purchase or holding of such Class M Certificate, Class B
Certificate or Residual Certificate will not result in the assets of the Trust
being deemed to be "plan assets" and subject to the prohibited transaction
provisions of ERISA and the Code and will not subject the Trustee, the
Depositor, the Servicer or the Seller to any obligation in addition to those
undertaken in this Agreement. No representation letter or Opinion of Counsel
delivered pursuant to this subsection 6.2(c) shall be an expense of the Trustee,
the Depositor, the Servicer or the Seller, but shall, in 



                                       95
<PAGE>   101

each case, be paid either by the Holder of the Class M Certificate, Class B
Certificate or Residual Certificate subject to the proposed Transfer or by the
proposed transferee.

         By its acceptance of a Class M Certificate, a Class B Certificate or
Residual Certificate, whether upon original issuance or subsequent transfer,
each Holder of such Certificate acknowledges the restrictions on transfer of
such Certificate set forth thereon and in this Agreement and agrees that it will
transfer such a Certificate only as provided herein. In addition, each purchaser
of a Class M Certificate in the form of a Book-Entry Certificate or a Class B
Certificate in the form of a Book-Entry Certificate shall be deemed to have made
the representation contained in paragraph 3 on the fifth page of Exhibit J
hereto.

         Each Person who has or who acquires any Ownership Interest in a
Residual Certificate shall be deemed by the acceptance or acquisition of such
Ownership Interest to have agreed to be bound by the following provisions and to
have irrevocably appointed the Depositor or its designee as its attorney-in-fact
to negotiate the terms of any mandatory sale under clause (vi) below and to
execute all instruments of Transfer and to do all other things necessary in
connection with any such sale, and the rights of each Person acquiring any
Ownership Interest in a Residual Certificate are expressly subject to the
following provisions:

               (i) Each Person holding or acquiring any Ownership Interest in a
         Residual Certificate shall be a Permitted Transferee, shall not be
         holding or acquiring such Ownership Interest on behalf of any Person
         that is not a Permitted Transferee and shall promptly notify the
         Trustee of any change or impending change in its status or the status
         of any beneficial owner as a Person who is not a Permitted Transferee.

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

             (iii) No Ownership Interest in a Residual Certificate may be
         transferred without the express written consent of the Trustee. In
         connection with any proposed registered Transfer of any Ownership
         Interest in a Residual Certificate, the Trustee shall, as a condition
         to such consent, require delivery to it of each of the following:

                   (A) an affidavit from the proposed transferee in the form
               attached as Exhibit M (a "Transfer Affidavit") to the effect that
               (a) such transferee is a Permitted Transferee and that it is not
               acquiring its Ownership Interest in the Residual Certificate that
               is the subject of the proposed Transfer as a nominee, trustee or
               agent for any Person who is not a Permitted Transferee; (b) the
               proposed transferee does not have the intention to impede the
               assessment or collection of tax legally required to be paid with
               respect to any Ownership Interest in a Residual Certificate; (c)
               it has no present knowledge or expectation that it will become
               insolvent or subject to a bankruptcy proceeding for so long as it
               holds any Ownership Interest in a Residual Certificate; and (d)
               it will abide by the provisions of clause (vii) below; and



                                       96
<PAGE>   102

                           (B) a covenant of the proposed transferee stating
                  that the proposed transferee agrees to be bound by and to
                  abide by the Transfer restrictions applicable to the Residual
                  Certificates.

                  (iv) Notwithstanding the delivery of a Transfer Affidavit by a
         proposed transferee under clause (iii) above, if an officer of the
         Trustee assigned to its Corporate Trust Administration Department has
         actual knowledge that the proposed transferee is not a Permitted
         Transferee, no Transfer of any Ownership Interest in a Residual
         Certificate to such proposed transferee shall be effected.

                  (v) Any attempted or purported registered Transfer of any
         Ownership Interest in a Residual Certificate in violation of the
         provisions of subsections 6.2(b) or (c) shall be absolutely null and
         void and shall vest no rights in the purported Transferee, to the
         extent permitted by applicable law. If any purported Transferee shall,
         in violation of the provisions of subsections 6.2(b) or (c), become a
         Holder of a Residual Certificate, the prior Holder of such Certificate
         that is a Permitted Transferee shall, upon discovery that the
         registration of Transfer of such Residual Certificate was not permitted
         by subsections 6.2(b) or (c), 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 subsections 6.2(b) or (c) or for making any
         distributions due on such Certificate to the Holder thereof or taking
         any other action with respect to such Holder under the provisions of
         the Agreement. The Trustee shall be entitled, but shall not be
         obligated, to recover from any Holder of a Residual Certificate that
         was not a Permitted Transferee at the time such distributions were made
         all distributions made on such Residual Certificate. Any such
         distributions so recovered by the Trustee shall be distributed and
         delivered by the Trustee to the prior Holder of such Certificate that
         is a Permitted Transferee.

                  (vi) If any Person other than a Person who is a Permitted
         Transferee acquires any Ownership Interest in a Residual Certificate in
         violation of the restrictions in subsections 6.2(b) or (c), the Trustee
         shall have the right, but shall not be obligated, without notice to the
         Holder of such Residual Certificate or any other Person having an
         Ownership Interest therein, to sell such Residual Certificate to a
         purchaser selected by the Trustee on such terms as the Trustee may
         choose. Such purchaser may be the Trustee itself or any affiliate of
         the Trustee. The proceeds of such sale, net of commissions (which may
         include commissions payable to the Trustee or its affiliates), expenses
         and taxes due, if any, shall be remitted by the Trustee to the previous
         Holder of such Residual Certificate that is a Permitted Transferee,
         except that in the event that the Trustee determines that the Holder of
         such Residual Certificate may be liable for any amount due under
         subsection 6.2(b) or (c) or any other provisions of this Agreement, the
         Trustee may withhold a corresponding amount from such remittance as
         security for such claim. The terms and conditions of any sale under
         this clause (vi) shall be determined in the sole discretion of the
         Trustee, and the Trustee shall not be liable to any Person having an
         Ownership Interest in a Residual Certificate as a result of its
         exercise of such discretion.



                                       97
<PAGE>   103

                  (vii) Each Person holding or acquiring any Ownership Interest
         in a Residual Certificate shall provide the Trustee with its written
         agreement (in form and substance satisfactory to the Trustee) (a) to
         require a Transfer Affidavit in the form of Exhibit M hereto from any
         other Person to whom such Person attempts to transfer any Ownership
         Interest in a Residual Certificate and (b) not to transfer any
         Ownership Interest in, or to cause the transfer of any Ownership
         Interest in, a Residual Certificate if it has actual knowledge that
         such other Person is not a Permitted Transferee or will be holding any
         Ownership Interest in a Residual Certificate on behalf of a Person that
         is not a Permitted Transferee.

         Upon notice to the Trustee by any Person, or if an officer of the
Trustee assigned to its Corporate Trustee Administration Department otherwise
has actual knowledge, that any Ownership Interest in a Residual Certificate has
been transferred, either directly or indirectly, to any Person that is not a
Permitted Transferee or an agent thereof (including a broker, nominee or
middleman) in contravention of the foregoing restrictions, the Trustee agrees to
furnish to the Internal Revenue Service and to the Person described in Section
860E(e)(3) of the Code the information described in Treasury Regulation Section
1.860D-1(b)(5)(ii), or any successor regulation thereto. Such information will
be provided in the manner described in Treasury Regulation Section
1.860E-2(a)(5), or any successor regulation thereto. The Trustee shall be
permitted to be reimbursed by such Person for the cost of providing such
information, but the Trustee shall in all events be required to furnish such
information.

         The foregoing provisions of the third and fourth paragraphs of
subsection 6.2(c) shall cease to apply to Transfers occurring on or after the
date on which there shall have been delivered to the Trustee, in form
satisfactory to the Trustee, a Nondisqualification Opinion.

         SECTION 6.3.      MUTILATED, DESTROYED, LOST OR STOLEN CERTIFICATES.

         If (i) any mutilated Certificate is surrendered to the Certificate
Registrar or the Certificate Registrar receives evidence to its satisfaction of
the destruction, loss or theft of any Certificate, and (ii) there is delivered
to the Trustee, the Depositor and the Certificate Registrar such reasonable
security or indemnity as may be required by them to save each of them harmless,
then, in the absence of notice to the Trustee or the Certificate Registrar that
such Certificate has been acquired by a bona fide purchaser, the Trustee shall
execute, authenticate and deliver, in exchange for or in lieu of any such
mutilated, destroyed, lost or stolen Certificate, a new Certificate of like
tenor and Percentage Interest. Upon the issuance of any new Certificate under
this Section 6.3, the Trustee or the Certificate Registrar may require the
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in relation thereto and any other expenses (including the fees
and expenses of the Trustee and the Certificate Registrar) connected therewith.
Any duplicate Certificate issued pursuant to this Section 6.3, shall constitute
complete and indefeasible evidence of ownership in the Trust, as if originally
issued, whether or not the lost, stolen or destroyed Certificate shall be found
at any time.

         SECTION 6.4.      PERSONS DEEMED OWNERS.

         Prior to due presentation of a Certificate for registration of
Transfer, the Seller, the Servicer, the Trustee, the Certificate Registrar, any
Paying Agent, and any agent of the Seller, the Servicer, the Trustee, any Paying
Agent or the Certificate Registrar may treat the Person, including a Depository,
in whose name any Certificate is registered as the owner (the "Owner") of such
Certificate for the purpose of receiving distributions pursuant to Section 5.1
and for all other purposes whatsoever, and none of the Seller, the Servicer, the
Depositor, the Trustee, the Certificate Registrar, nor any agent of any of them
shall be affected by notice to the contrary.

         SECTION 6.5.      APPOINTMENT OF PAYING AGENT.

         (a) The Paying Agent shall make distributions to the Holders of
Certificates from the Distribution Account pursuant to Section 5.1 and shall
report the amounts of such distributions to the Trustee. The duties of the
Paying Agent may include the obligation (i) to withdraw funds from the
Distribution Account for the purpose of making the distributions referred to
above and (ii) to distribute statements and provide information to
Certificateholders as required hereunder. The Paying Agent hereunder shall at
all times be a national banking association or a corporation duly incorporated
and validly existing under the laws of the United States of America or any state
thereof, authorized under such laws to exercise corporate trust powers and
subject to supervision or examination by federal or state authorities. The
Paying Agent shall initially be the Trustee. The Trustee may appoint a successor
Paying Agent, which appointment shall be reasonably satisfactory to the
Depositor and the Seller.

         (b) The Trustee shall cause the Paying Agent (if other than the
Trustee) to execute and deliver to the Trustee an instrument in which such
Paying Agent shall agree with the Trustee that such Paying Agent shall hold all
sums, if any, held by it for payment to the Holders of Certificates in trust for
the benefit of the Holders of Certificates entitled thereto until such sums
shall be paid to such Certificateholders and shall agree that it shall comply
with all requirements of the Code regarding the withholding of payments in
respect of federal income taxes due from Certificate Owners and otherwise comply
with the provisions of this Agreement applicable to it.

         SECTION 6.6.      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 Minneapolis, Minnesota where
Certificates may be surrendered for registration of transfer or exchange. The
Trustee initially designates its Corporate Trust Office 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 VII

                   THE DEPOSITOR, THE SELLER AND THE SERVICER

         SECTION 7.1.      LIABILITY OF THE DEPOSITOR, THE SELLER AND THE 
SERVICER.

         The Seller and the Servicer shall be liable in accordance herewith only
to the extent of the obligations specifically imposed upon and undertaken by the
Seller and the Servicer, as the case may be, herein. The Depositor shall be
liable in accordance herewith only to the extent of the obligations specifically
imposed upon and undertaken by the Depositor.

         SECTION 7.2.      MERGER OR CONSOLIDATION OF, OR ASSUMPTION OF 
THE OBLIGATIONS OF, THE SELLER OR THE SERVICER.

         Any corporation into which the Depositor, the Seller or the Servicer
may be merged or consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Depositor, the Seller or the Servicer
shall be a party, or any corporation succeeding to the business of the
Depositor, the Seller or the Servicer shall be the successor of the Depositor,
the Seller or the 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.

         SECTION 7.3.      LIMITATION ON LIABILITY OF THE SERVICER AND OTHERS.

         Neither the Servicer nor any of the directors or officers or employees
or agents of the Servicer shall be under any liability to the Trust or the
Certificateholders for any action taken or for refraining from the taking of any
action by the Servicer in good faith pursuant to this Agreement, or for errors
in judgment; provided, however, that this provision shall not protect the
Servicer or any such Person against any liability which would otherwise be
imposed by reason of its willful misfeasance, bad faith or gross negligence in
the performance of duties of the Servicer or by reason of its reckless disregard
of its obligations and duties of the Servicer hereunder. The Servicer and any
director or officer or employee or agent of the 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 Servicer and any director
or officer or employee or agent of the Servicer shall be indemnified by the
Trust and held harmless against any loss, liability or expense incurred in
connection with any legal action relating to this Agreement or the Certificates,
other than any loss, liability or expense related to any specific Mortgage Loan
or Mortgage Loans (except as any such loss, liability or expense shall be
otherwise reimbursable pursuant to this Agreement) or related to the Servicer's
failure to perform its obligations under this Agreement or 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. The Servicer shall not be under
any obligation to appear in, prosecute or defend any legal action which is not
incidental to duties to service the Mortgage Loans in accordance with this
Agreement, and which in its opinion may involve it in any expense or liability;
provided, however, that the Servicer may in its sole discretion undertake



                                      100
<PAGE>   106

any such action which it may deem necessary or desirable in respect of this
Agreement, and the rights and duties of the parties hereto and the interests of
the Certificateholders hereunder. In such event, the reasonable legal expenses
and costs of such action and any liability resulting therefrom shall be
expenses, costs and liabilities of the Trust and the Servicer shall be entitled
to be reimbursed therefor. The Servicer's right to indemnity or reimbursement
pursuant to this Section 7.3 shall survive any resignation or termination of the
Servicer pursuant to Section 7.4 or 8.1 with respect to any losses, expenses,
costs or liabilities arising prior to such resignation or termination (or
arising from events that occurred prior to such resignation or termination).

         SECTION 7.4.      SERVICER NOT TO RESIGN.

         Subject to the provisions of Section 7.2, the Servicer shall not resign
from the obligations and duties hereby imposed on it except (i) upon
determination that the performance of its obligations or duties hereunder are no
longer permissible under applicable law or are in material conflict by reason of
applicable law with any other activities carried on by it or its subsidiaries or
Affiliates, the other activities of the Servicer so causing such a conflict
being of a type and nature carried on by the Servicer or its subsidiaries or
Affiliates at the date of this Agreement or (ii) upon satisfaction of the
following conditions: (a) the Servicer has proposed a successor Servicer to the
Trustee in writing and such proposed successor Servicer is reasonably acceptable
to the Trustee; and (b) each Rating Agency shall have delivered a letter to the
Trustee prior to the appointment of the successor Servicer stating that the
proposed appointment of such successor Servicer as Servicer hereunder will not
result in the reduction or withdrawal of the then current rating of any Class of
Certificates; provided, however, that no such resignation by the Servicer shall
become effective until such successor Servicer or, in the case of (i) above, the
Trustee shall have assumed the Servicer's responsibilities and obligations
hereunder (including, without limitation the obligations of the Servicer under
Section 3.4) or the Trustee shall have designated a successor Servicer in
accordance with Section 8.2. Any such resignation shall not relieve the Servicer
of responsibility for any of the obligations specified in Sections 8.1 and 8.2
as obligations that survive the resignation or termination of the Servicer. Any
such determination permitting the resignation of the Servicer pursuant to clause
(i) above shall be evidenced by an Opinion of Counsel to such effect delivered
to the Trustee and the Certificateholders. The Servicer shall have no claim
(whether by subrogation or otherwise) or other action against any
Certificateholder for any amounts paid by the Servicer pursuant to any provision
of this Agreement. The Trustee shall provide written notice to each Holder of a
Certificate promptly after any resignation by the Servicer hereunder.

         SECTION 7.5.      DELEGATION OF DUTIES.

         In the ordinary course of business, the Servicer at any time may
delegate any of its duties hereunder to any Person, including any of its
Affiliates, who agrees to conduct such duties in accordance with standards
comparable to those with which the Servicer complies pursuant to Section 3.1.
Such delegation shall not relieve the Servicer of its liabilities and
responsibilities with respect to such duties and shall not constitute a
resignation within the meaning of Section 7.4. The Servicer shall provide the
Trustee with written notice prior to the delegation of any of its duties to any
Person other than any of the Servicer's Affiliates or their respective
successors and assigns.

<PAGE>   107

         SECTION 7.6.      INDEMNIFICATION OF THE TRUST BY THE SELLER AND
SERVICER.

         (a) The Servicer shall indemnify and hold harmless the Trust and the
Trustee from and against any loss, liability, expense, damage or injury suffered
or sustained by reason of the Servicer's activities or omissions in servicing or
administering the Mortgage Loans that are not in accordance with this Agreement,
including, but not limited to, any judgment, award, settlement, reasonable
attorneys' fees and other costs or expenses incurred in connection with the
defense of any actual or threatened action, proceeding or claim related to the
Servicer's failure to perform hereunder. Any such indemnification shall not be
payable from the assets of the Trust. The provisions of this indemnity shall run
directly to and be enforceable by an injured party subject to the limitations
hereof.

         (b) Notwithstanding anything to the contrary contained herein, the
Seller (i) agrees to be liable directly to the injured party for the entire
amount and (ii) shall indemnify and hold harmless the Trust and the Trustee from
and against any loss, liability, expense, damage, claim or injury (including,
without limitation, any prohibited transactions tax imposed on the Trust, but
excluding any loss, liability, expense, damage, claim or injury attributable to
a Holder of a Regular Certificate in its capacity as an investor in such
Certificate as a result of defaults on the Mortgage Loans) arising out of or
based on this Agreement by reason of any acts, omissions, or alleged acts or
omissions arising out of activities of the Trust or the Trustee, or the actions
of the Servicer including, in either case, but not limited to, amounts payable
to the Servicer pursuant to Section 7.3, any judgment, award, settlement,
reasonable attorneys' fees and other costs or expenses incurred in connection
with the defense of any actual or threatened action, proceeding or claim;
provided, that the Seller shall not indemnify the Trustee (but shall indemnify
any other injured party) if such loss, liability, expense, damage or injury is
due to the Trustee's willful malfeasance, bad faith or negligence or by reason
of the Trustee's reckless disregard of its obligations hereunder. The provisions
of this indemnity shall run directly to and be enforceable by an injured party
subject to the limitations hereof. The provisions of this Section shall survive
the termination of the Agreement.


                                  ARTICLE VIII

                                     DEFAULT

         SECTION 8.1.      EVENTS OF DEFAULT.

         If any one of the following events (an "Event of Default") shall occur
and be continuing:

                  (i) (A) The failure by the Servicer to make any Monthly
         Advance; or (B) any other failure by the Servicer to deposit in any
         Account any deposit required to be made under the terms of this
         Agreement which continues unremedied for a period of two Business Days
         after the earlier of the (a) knowledge of the Servicer of such failure
         and (b) the date upon which written notice of such failure, requiring
         the same to be remedied, and 



                                      102
<PAGE>   108

         stating that such notice is a "Notice of Default" hereunder, shall
         have been given to the Servicer by the Trustee or to the Servicer and
         the Trustee by any Certificateholder; or

                  (ii)  The failure by the Servicer to make any required
         Servicing Advance which failure continues unremedied for a period of 30
         days, or the failure on the part of the Servicer duly to observe or
         perform in any material respect any other covenants or agreements of
         the Servicer set forth in the Certificates or in this Agreement, which
         failure, in each case, materially and adversely affects the interests
         of Certificateholders and which continues unremedied for a period of 60
         days after the earlier of (a) knowledge of the Servicer of such failure
         and (b) date on which written notice of such failure, requiring the
         same to be remedied, and stating that such notice is a "Notice of
         Default" hereunder, shall have been given to the Servicer by the
         Trustee or to the Servicer and the Trustee by any Certificateholder; or

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

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

                  (v)   Any breach by the Servicer of a representation or
         warranty made in Section 2.4, which breach continues unremedied for a
         period of 60 days after the earlier of (a) knowledge of the Servicer
         of such failure and (b) the date on which written notice of such
         breach, requiring the same to be remedied, and stating that such
         notice is a "Notice of Default" hereunder, shall have been given to
         the Servicer by the Trustee or to the Servicer and the Trustee by any
         Certificateholder; or

                  (vi)  the occurrence of a Servicer Removal Right Event;

then, and in each and every such case, so long as an Event of Default shall not
have been remedied by the Servicer within the time periods provided for above,
(x) subject to the succeeding paragraph, with respect solely to clause (i)(A)
above, if such Monthly Advance is not made by 4:00 P.M. New York time on the
second Business Day following written notice to the Servicer of such event, the
Trustee shall terminate all of the rights and obligations of the Servicer under
this Agreement and the Trustee, or a successor Servicer appointed in accordance
with Section 8.2, shall immediately make such Monthly Advance and assume,
pursuant to Section 8.2 hereof, the duties of a successor Servicer and (y) in
the case of clause (i)(B), (ii), (iii), (iv), (v), or 


                                      103
<PAGE>   109

(vi), the Trustee shall, at the direction of the Holders of each Class
Certificates evidencing Percentage Interests aggregating not less than 51% by
notice then given in writing to the Servicer, terminate all of the rights and
obligations of the Servicer as Servicer under this Agreement. Upon the Trustee's
obtaining actual knowledge that a required amount described in clause (i) above
has not been made by the Servicer, the Trustee shall notify the Servicer in
writing as soon as is reasonably practical. Any such notice to the Servicer
shall also be given to each Rating Agency and each Certificateholder. On or
after the receipt by the Servicer of such written notice, all authority and
power of the Servicer under this Agreement, whether with respect to the
Certificates or the Mortgage Loans or otherwise, shall pass to and be vested in
the Trustee pursuant to and under this Section 8.1; and, without limitation, the
Trustee is hereby authorized and empowered to execute and deliver, on behalf of
the Servicer as attorney-in-fact or otherwise, any and all documents and other
instruments, and to do or accomplish all other acts or things necessary or
appropriate to effect the purposes of such notice of termination, whether to
complete the transfer and endorsement of each Mortgage Loan and related
documents, or otherwise. The Servicer agrees to cooperate with the Trustee in
effecting the termination of the responsibilities and rights of the Servicer
hereunder, including, without limitation, the transfer to the Trustee for the
administration by it of all cash amounts that shall at the time be held by the
Servicer and to be deposited by it in the Collection Account, or that have been
deposited by the Servicer in the Collection Account or thereafter received by
the Servicer with respect to the Mortgage Loans. All costs and expenses
(including attorneys' fees) incurred in connection with transferring the
Mortgage Files to the successor Servicer and amending this Agreement to reflect
such succession as Servicer pursuant to this Section 8.1 shall be paid by the
predecessor Servicer (or if the predecessor Servicer is the Trustee, the initial
Servicer) upon presentation of reasonable documentation of such costs and
expenses.

         Notwithstanding the foregoing, a delay in or failure of performance
under Section 8.1(i) for a period of ten Business Days or under Section 8.1(ii)
for a period of 30 Business Days, shall not constitute an Event of Default if
such delay or failure could not be prevented by the existence of reasonable
diligence by the Servicer and such delay or failure was caused by an act of God
or the public enemy, acts of declared or undeclared war, public disorder,
rebellion or sabotage, epidemics, landslides, lightning, fire, hurricanes,
earthquakes, floods or similar causes. The preceding sentence shall not relieve
the Servicer from using its best efforts to perform its respective obligations
in a timely manner in accordance with the terms of this Agreement and the
Servicer shall provide the Trustee and the Certificateholders with an Officers'
Certificate giving prompt notice of such failure or delay by it, together with a
description of its efforts to so perform its obligations. The Servicer shall
immediately notify the Trustee in writing of any Event of Default and such
notice shall include references to this Agreement, the Trust, and the
Certificates. Furthermore, for purposes of this Section 8.1, the Trustee shall
not be deemed to have knowledge of an Event of Default unless a Responsible
Officer of the Trustee assigned to and working in the Corporate Trust Office has
actual knowledge thereof or unless written notice of any event which is in fact
such an Event of Default is received by the Trustee.

         SECTION 8.2.      TRUSTEE TO ACT; APPOINTMENT OF SUCCESSOR.

         (a) On and after the time the Servicer receives a notice of termination
pursuant to Section 8.1 or has resigned pursuant to Section 7.4, the Trustee
shall be the successor in all


                                      104
<PAGE>   110

respects to the Servicer in its capacity as 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
Servicer by the terms and provisions hereof. As compensation therefor, the
Trustee shall be entitled to all such compensation and expenses as the Servicer
would have been entitled to hereunder if no such notice of termination had been
given. Notwithstanding the above, (i) if the Trustee is unwilling to act as
successor Servicer, or (ii) if the Trustee is legally unable so to act, the
Trustee may (in the situation described in clause (i) above) or shall (in the
situation described in clause (ii) above) appoint or petition a court of
competent jurisdiction to appoint, any established housing and home finance
institution, bank or other mortgage loan servicer having a net worth of not less
than $50,000,000 as the successor to the Servicer hereunder in the assumption of
all or any part of the responsibilities, duties or liabilities of the Servicer
hereunder. Pending appointment of a successor to the Servicer hereunder, unless
the Trustee is prohibited by law from so acting, the Trustee shall act in such
capacity as hereinabove provided. In connection with such appointment and
assumption, the successor shall be entitled to receive compensation out of
payments on Mortgage Loans in an amount equal to the compensation and expenses
which the Servicer would otherwise have received pursuant to Section 3.9 (or
such lesser compensation as the Trustee and such successor shall agree). The
appointment of a successor Servicer shall not affect any liability of the
predecessor Servicer which may have arisen under this Agreement prior to its
termination as Servicer (including, without limitation, the obligation to pay
any deductible under an insurance policy pursuant to Section 3.5 or to indemnify
the Trustee pursuant to Section 7.6), nor shall any successor Servicer be liable
for any acts or omissions of the predecessor Servicer or for any breach by such
Servicer of any of its representations or warranties contained herein or in any
related document or agreement. The Trustee and such successor shall take such
action, consistent with this Agreement, as shall be necessary to effectuate any
such succession.

         (b) Any successor, including the Trustee, to the Servicer as Servicer
shall during the term of its service as Servicer (i) continue to service and
administer the Mortgage Loans for the benefit of Certificateholders and (ii)
maintain in force a policy or policies of insurance covering errors and
omissions in the performance of its obligations as Servicer hereunder and a
fidelity bond in respect of its officers, employees and agents to the same
extent as the Servicer is so required pursuant to Section 3.13.

         SECTION 8.3.      WAIVER OF DEFAULTS.

         The Trustee may, on behalf of all Certificateholders, waive any events
permitting removal of the Servicer as servicer pursuant to this Article VIII,
provided, however, that the Trustee may not waive a default in making a required
distribution on a Certificate without the consent of the Holder of such
Certificate. Upon any waiver of a past default, such default shall cease to
exist, and any Event of Default arising therefrom shall be deemed to have been
remedied for every purpose of this Agreement. No such waiver shall extend to any
subsequent or other default or impair any right consequent thereto except to the
extent expressly so waived.

         SECTION 8.4.      NOTIFICATION TO CERTIFICATEHOLDERS.

         Upon any termination or appointment of a successor to the Servicer
pursuant to this Article VIII or Section 7.4, the Trustee shall give prompt
written notice thereof to the Certificateholders at their respective addresses
appearing in the Certificate Register and each Rating Agency.


                                   ARTICLE IX

                                   THE TRUSTEE

         SECTION 9.1.      DUTIES OF TRUSTEE.

         The Trustee, prior to the occurrence of an Event of Default and after
the curing of all Events of Default which may have occurred, undertakes to
perform such duties and only such duties as are specifically set forth in this
Agreement. If an Event of Default has occurred (which has not been cured) of
which a Responsible Officer of the Trustee has actual knowledge, 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 his or her own
affairs.

         The Trustee represents and warrants to the Seller, the Servicer and the
Depositor that the Trustee's computer and other systems used in performing its
duties and obligations under this Agreement will be modified and maintained to
operate in a manner such that at all times, including on and after January 1,
2000, (1) the Trustee can perform such duties and obligations in accordance with
the terms of this Agreement and (2) the Trustee can operate its business in the
same manner as it is operating on the date hereof.

         The Trustee, upon receipt of all resolutions, certificates, statements,
opinions, reports, documents, orders or other instruments furnished to the
Trustee which are specifically required to be furnished pursuant to any
provision of this Agreement, shall examine them to determine whether they are in
the form required by this Agreement; provided, however, that the Trustee will
not be responsible for the accuracy or content of any such resolutions,
certificates, statements, opinions, reports, documents, orders or other
instruments.

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

                  (i) prior to the occurrence of an Event of Default, and after
         the curing of all such Events of Default which may have occurred, the
         duties and obligations of the Trustee shall be determined solely by the
         express provisions of this Agreement, the Trustee shall not be liable
         except for the performance of such duties and obligations as are
         specifically set forth in this Agreement, no implied covenants or
         obligations shall be read into this Agreement against the Trustee and,
         in the absence of bad faith on the part of


                                      106
<PAGE>   112

         the Trustee, the Trustee may conclusively rely, as to the truth of the
         statements and the correctness of the opinions expressed therein, upon
         any certificates or opinions furnished to the Trustee and conforming to
         the requirements of this Agreement;

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

                  (iii) the Trustee shall not be personally liable with respect
         to any action taken, suffered or omitted to be taken by it in good
         faith in accordance with the consent or direction of the
         Certificateholders under this Agreement; and

                  (iv)  the Trustee shall not be charged with knowledge of any
         failure by the Servicer to comply with the obligations of the Servicer
         referred to in clauses (i) and (ii) of Section 8.1 unless a Responsible
         Officer of the Trustee at the Corporate Trust Office obtains actual
         knowledge of such failure or the Trustee receives written notice of
         such failure from the Servicer.

         The Trustee shall not be required to expend or risk its own funds or
otherwise incur financial liability in the performance of any of its duties
hereunder, or in the exercise of any of its rights or powers, if there is
reasonable ground for believing that the repayment of such funds or adequate
indemnity against such risk or liability is not reasonably assured to it, and
none of the provisions contained in this Agreement shall in any event require
the Trustee to perform, or be responsible for the manner of performance of, any
of the obligations of the Depositor, the Seller or the Servicer under this
Agreement, except during such time, if any, as the Trustee shall be the
successor to, and be vested with the rights, duties, powers and privileges of,
the Servicer in accordance with the terms of this Agreement.

         SECTION 9.2.      CERTAIN MATTERS AFFECTING THE TRUSTEE.

         Except as otherwise provided in Section 9.1:

                  (i)   the Trustee may request and rely upon, and shall be
         protected in acting or refraining from acting upon, any resolution,
         Officer's Certificate, certificate of auditors or any other
         certificate, statement, instrument, opinion, report, notice, request,
         consent, order, appraisal, bond or other paper or document reasonably
         believed by it to be genuine and to have been signed or presented by
         the proper party or parties, and the manner of obtaining consents and
         of evidencing the authorization of the execution thereof by
         Certificateholders shall be subject to such reasonable regulations as
         the Trustee may prescribe;

                  (ii)  the Trustee may consult with counsel and any written
         advice of such counsel or 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 advice or Opinion of Counsel;



                                      107
<PAGE>   113

                  (iii) the Trustee shall be under no obligation to exercise any
         of the 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 against the costs, expenses and
         liabilities which may be incurred therein or thereby; the right of the
         Trustee to perform any discretionary act enumerated in this Agreement
         shall not be construed as a duty, and the Trustee shall not be
         answerable for other than its negligence or willful misconduct in the
         performance of any such act; nothing contained herein shall, however,
         relieve the Trustee of the obligations, upon the occurrence of an Event
         of Default (which has not been cured) of which a Responsible Officer of
         the Trustee has actual knowledge, to exercise such of the rights and
         powers vested in it by this Agreement, and to use the same degree of
         care and skill in their exercise as a prudent person would exercise or
         use under the circumstances in the conduct of his or her own affairs;

                  (iv)  the Trustee shall not be personally 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;

                  (v)   prior to the occurrence of an Event of Default and after
         the curing of all Events of Default which may have occurred, the
         Trustee shall not be bound to make any investigation into the facts or
         matters stated in any resolution, certificate, statement, instrument,
         opinion, report, notice, request, consent, order, approval, bond or
         other paper or documents; provided, however, that if the payment within
         a reasonable time to the Trustee of the costs, expenses or liabilities
         likely to be incurred by it in the making of such investigation is, in
         the opinion of the Trustee, not reasonably assured to the Trustee by
         the security afforded to it by the terms of this Agreement, the Trustee
         may require reasonable indemnity against such cost, expense or
         liability as a condition to such proceeding. The reasonable expense of
         every such examination shall be paid by the Servicer or, if paid by the
         Trustee, shall be reimbursed by the Servicer upon demand. Nothing in
         this clause (v) shall derogate from the obligation of the Servicer to
         observe any applicable law prohibiting disclosure of information
         regarding the Mortgagors;

                  (vi)  the Trustee shall not be accountable, shall have no
         liability and makes no representation as to any acts or omissions
         hereunder of the Servicer until such time as the Trustee may be
         required to act as Servicer pursuant to Section 8.2 and thereupon only
         for the acts or omissions of the Trustee as successor Servicer; and

                  (vii) the Trustee may execute any of the trusts or powers
         hereunder or perform any duties hereunder either directly or by or
         through agents or attorneys or a custodian.

         SECTION 9.3.   TRUSTEE NOT LIABLE FOR CERTIFICATES OR MORTGAGE LOANS.

         The recitals contained herein and in the Certificates (other than the
authentication of the Trustee on the Certificates) shall be taken as the
statements of the Depositor, and the Trustee


                                      108
<PAGE>   114

assumes no responsibility for the correctness of the same. The Trustee makes no
representations as to the validity or sufficiency of this Agreement or of the
Certificates (other than the signature and authentication of the Trustee on the
Certificates) or of any Mortgage Loan or related document. The Trustee shall not
be accountable for the use or application by the Servicer of any of the
Certificates or of the proceeds of such Certificates, or for the use or
application of any funds paid to the Servicer in respect of the Mortgage Loans
or deposited in or withdrawn from the Collection Account by the Servicer. The
Trustee shall at no time have any responsibility or liability for or with
respect to the legality, validity and enforceability of any Mortgage or any
Mortgage Loan, or the perfection and priority of any mortgage or the maintenance
of any such perfection and priority or for or with respect to the sufficiency of
the Trust or its ability to generate the payments to be distributed to
Certificateholders under this Agreement, including, without limitation: the
existence, condition and ownership of any Mortgaged Property; the existence and
enforceability of any hazard insurance thereon (other than if the Trustee shall
assume the duties of the Servicer pursuant to Section 8.2 and thereupon only for
the acts or omissions of the successor Servicer); the validity of the assignment
of any Mortgage Loan to the Trustee or of any intervening assignment; the
completeness of any Mortgage Loan; the performance or enforcement of any
Mortgage Loan (other than if the Trustee shall assume the duties of the Servicer
pursuant to Section 8.2 and thereupon only for the acts or omissions of the
Trustee as successor Servicer); the compliance by the Depositor or the Servicer
with any warranty or representation made under this Agreement or in any related
document or the accuracy of any such warranty or representation; any investment
of monies by or at the direction of the Servicer or any loss resulting
therefrom, it being understood that the Trustee shall remain responsible for any
Trust property that it may hold in its individual capacity; the acts or
omissions of any of the Depositor, the Servicer (other than if the Trustee shall
assume the duties of the Servicer pursuant to Section 8.2 and thereupon only for
the acts or omissions of the Trustee as successor Servicer), any subservicer or
any Mortgagor; any action of the Servicer (other than if the Trustee shall
assume the duties of the Servicer pursuant to Section 8.2 and thereupon only for
the acts or omissions of the Trustee as successor Servicer), or any Subservicer
taken in the name of the Trustee; the failure of the Servicer or any Subservicer
to act or perform any duties acquired of it as agent of the Trustee hereunder;
or any action by the Trustee taken at the instruction of the Servicer (other
than if the Trustee shall assume the duties of the Servicer pursuant to Section
8.2 and thereupon only for the acts or omissions of the Trustee as successor
Servicer); provided, however, that the foregoing shall not relieve the Trustee
of its obligation to perform its duties under this Agreement, including, without
limitation, the Trustee's review of the Mortgage Files pursuant to Section
2.1(c). The Trustee shall have no responsibility for filing any financing or
continuation statement in any public office at any time or to otherwise perfect
or maintain the perfection of any security interest or lien granted to it
hereunder (unless the Trustee shall have become the successor Servicer).

         SECTION 9.4.      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
were not Trustee and may transact any banking and/or trust business with the
Depositor, the Seller, the Servicer or their Affiliates.



                                      109
<PAGE>   115

         SECTION 9.5.      TRUSTEE'S AND DOCUMENT CUSTODIAN'S EXPENSES.

         The Trustee shall be entitled to receive the Trustee Fee pursuant to
Section 5.1(a)(i) and, unless payable by the Servicer pursuant to Section
7.6(a), the Seller will pay or reimburse the Trustee upon its request for all
reasonable expenses, disbursements and advances incurred or made by the Trustee
in accordance with any of the provisions of this Agreement or any other
agreement related hereto (including the reasonable compensation and the expenses
and disbursements of its counsel and of all persons not regularly in its employ)
except any such expense, disbursement or advance as may arise from its
negligence or bad faith or which is the responsibility of Certificateholders
hereunder. In addition, unless payable by the Servicer pursuant to Section
7.6(a), the Seller covenants and agrees to indemnify the Trustee and any
directors, officers, employees and agents of the Trustee from, and hold it
harmless against, any and all losses, liabilities, damages, claims or expenses
other than those resulting from the Trustee's negligence or bad faith of the
Trustee. In the event the Servicer fails to perform its obligations hereunder,
then the Trustee shall be indemnified by the Trust for the payment of the
Trustee's monthly fee which right of the Trustee shall have priority over all
other distributions and payments from the Distribution Account. This section
shall survive termination of this Agreement or the resignation or removal of any
Trustee hereunder.

         The Document Custodian shall be entitled to receive the fee agreed to
with the Seller. In addition, the Seller covenants and agrees to indemnify the
Document Custodian and any directors, officers, employees and agents of the
Document Custodian from, and hold it harmless against, any and all losses,
liabilities, damages, claims or expenses other than those resulting from the
Document Custodian's negligence or bad faith of the Document Custodian. This
section shall survive termination of this Agreement or the resignation or
removal of any Document Custodian hereunder.

         SECTION 9.6.      ELIGIBILITY REQUIREMENTS FOR TRUSTEE.

         The Trustee hereunder shall at all times be a national banking
association or a corporation duly incorporated and validly existing under the
laws of the United States of America or any state thereof, 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 having (or in the case of a bank or corporation included in
a bank holding company system, the related bank holding company shall have) a
rating with respect to its long-term unsecured debt obligations of at least A-
by S&P (or such lower rating as such Rating Agency may from time to time agree).
If such corporation publishes reports of condition at least annually, pursuant
to law or to the requirements of the aforesaid supervising or examining
authority, then for the purposes of this Section 9.6, the combined capital and
surplus of such corporation shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. The
principal office of the Trustee (other than the initial Trustee) shall be in a
state with respect to which an Opinion of Counsel has been delivered to such
Trustee at the time such Trustee is appointed Trustee to the effect that the
Trust will not be a taxable entity under the laws of such state. In case at any
time the Trustee shall cease to be eligible in accordance with the provisions of
this Section 9.6, the Trustee shall resign immediately in the manner and with
the effect specified in Section 9.7.



                                      110
<PAGE>   116

         SECTION 9.7.      RESIGNATION OR REMOVAL OF TRUSTEE.

         The Trustee may at any time resign and be discharged from the trusts
hereby created by giving written notice thereof to the Depositor, the Seller,
the Servicer and each Rating Agency. Upon receiving such notice of resignation,
Depositor shall promptly appoint a successor Trustee by written instrument, in
duplicate, one copy of which instrument shall be delivered to the resigning
Trustee and one copy to the successor Trustee; provided, however, that any such
successor Trustee shall be subject to the prior written approval of the
Servicer. If no successor Trustee shall have been so appointed and having
accepted appointment within 30 days after the giving of such notice of
resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor Trustee.

         If at any time the Trustee shall cease to be eligible in accordance
with the provisions of Section 9.6 and shall fail to resign after written
request therefor by the Depositor, or if at any time the Trustee shall be
legally unable to act, or shall be adjudged a bankrupt or insolvent, or a
receiver of the Trustee or of its property shall be appointed, or any public
officer shall take charge or control of the Trustee or of its property or
affairs for the purpose of rehabilitation, conservation or liquidation, or if a
tax is imposed or threatened with respect to the Trust by any state in which the
Trustee is located, then the Depositor may remove the Trustee. If the Depositor
removes the Trustee under the authority of the immediately preceding sentence,
the Depositor shall promptly appoint a successor Trustee by written instrument,
in duplicate, one copy of which instrument shall be delivered to the Trustee so
removed and one copy to the successor trustee. Immediately upon its appointment
and qualification hereunder, the successor Trustee shall provide written notice
to each Holder of a Certificate of its appointment and qualification.

         The Holders of Certificates evidencing Percentage Interests aggregating
at least 51% may at any time remove the Trustee by written instrument or
instruments delivered to the Depositor, the Servicer, the Seller and the Trustee
and shall thereupon use their best efforts to appoint a successor trustee in
accordance with this Section.

         Any resignation or removal of the Trustee and appointment of a
successor Trustee pursuant to any of the provisions of this Section 9.7 shall
not become effective until acceptance of appointment by the successor Trustee as
provided in Section 9.8.

         SECTION 9.8.      SUCCESSOR TRUSTEE.

         Any successor Trustee appointed as provided in Section 9.7 shall
execute, acknowledge and deliver to the Depositor and to its predecessor Trustee
an instrument accepting such appointment hereunder, and thereupon the
resignation or removal of the predecessor Trustee shall become effective and
such successor Trustee, without any further act, deed or conveyance, shall
become fully vested with all the rights, powers, duties and obligations of its
predecessor hereunder, with like effect as if originally named as Trustee. The
Depositor, the Servicer and the predecessor Trustee shall execute and deliver
such instruments and do such other things as may 


                                      111
<PAGE>   117

reasonably be required for 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 9.8 unless at the time of such acceptance such successor Trustee shall
be eligible under the provisions of Section 9.6.

         Upon acceptance of appointment by a successor Trustee as provided in
this Section 9.8, the Servicer shall mail notice of the succession of such
Trustee hereunder to all Holders of Certificates at their addresses as shown in
the Certificate Register and to each Rating Agency. If the Servicer fails to
mail such notice within 30 days after acceptance of appointment by the successor
Trustee, the successor Trustee shall cause such notice to be mailed at the
expense of the Servicer.

         SECTION 9.9.      MERGER OR CONSOLIDATION OF TRUSTEE.

         Any Person into which the Trustee may be merged or converted or with
which it may be consolidated, or any Person resulting from any, merger,
conversion or consolidation to which the Trustee shall be a party, or any Person
succeeding to all or substantially all of the corporate trust business of the
Trustee, shall be the successor of the Trustee hereunder, provided such Person
shall be eligible under the provisions of Section 9.6, without the execution or
filing of any paper or any further act on the part of any of the parties hereto,
anything herein to the contrary notwithstanding.

         SECTION 9.10.     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 or any Mortgaged Property may at the time be located, the
Depositor and the Trustee shall each 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, and to vest in
such Person or Persons, in such capacity and for the benefit of the
Certificateholders, such title to the Trust, or any part thereof, and, subject
to the other provisions of this Section 9.10, such powers, duties, obligations,
rights and trusts as the Servicer and the Trustee may consider necessary or
desirable. The parties hereto acknowledge that any such co-trustee or separate
trustee will act as co-trustee or separate trustee hereunder pursuant to any
co-trustee agreement between the Trustee and such co-trustee or separate
Trustee, and shall be entitled to the same rights and subject to the same
standards as the Trustee with respect to all rights and immunities of the
Trustee, including with respect to indemnification and the obligations and
duties of the Depositor, the Seller or the Servicer to the Trustee pursuant to
the terms hereof. Any such co-trustee or separate trustee shall be subject to
the written approval of the Servicer. If the Servicer shall not have joined in
such appointment within 15 days after the receipt by it of a request so to do,
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 9.6 and no notice to Certificateholders of the



                                      112
<PAGE>   118

appointment of any co-trustee or separate trustee shall be required under
Section 9.8. The Servicer shall be responsible for the fees of any co-trustee or
separate trustee appointed hereunder.

         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)   all rights, powers, duties and obligations conferred or
         imposed upon the Trustee shall be conferred or imposed upon and
         exercised or performed by the Trustee and such separate trustee or
         co-trustee jointly (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 Servicer
         hereunder), the Trustee shall be incompetent or unqualified to perform
         such act or acts, in which event such rights, powers, duties and
         obligations (including the holding of title to the Trust 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

                  (iii) the Servicer and the Trustee may each at any time accept
         the resignation of or remove any separate trustee or co-trustee except
         that following the occurrence of an Event of Default, the Trustee
         acting alone may accept the resignation or remove any 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 then separate trustees and co-trustees,
as effectively as if given to each of them. Every instrument appointing any
separate trustee or co-trustee shall refer to this Agreement and the conditions
of this Article IX. Each separate trustee and co-trustee, upon its acceptance of
the trusts conferred, shall be vested with the estates or property specified in
its instrument of appointment, either jointly with the Trustee or separately, as
may be provided therein, subject to all the provisions of this Agreement,
specifically including every provision of this Agreement relating to the conduct
of, affecting the liability of, or affording protection to, the Trustee. Every
such instrument shall be filed with the Trustee and a copy thereof given to the
Depositor and the Servicer.

         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 9.11.     LIMITATION OF LIABILITY.

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

         SECTION 9.12.     TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF
CERTIFICATES.

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

         SECTION 9.13.     SUITS FOR ENFORCEMENT.

         In case an Event of Default or other default by the Servicer, the
Seller or the Depositor hereunder shall occur and be continuing, the Trustee, in
its discretion, may proceed to protect and enforce its rights and the rights of
the Holders of Certificates under this Agreement by a suit, action or proceeding
in equity or at law or otherwise, whether for the specific performance of any
covenant or agreement contained in this Agreement or in aid of the execution of
any power granted in this Agreement or for the enforcement of any other legal,
equitable or other remedy, as the Trustee, being advised by counsel, shall deem
most effectual to protect and enforce any of the rights of the Trustee and the
Certificateholders.

         SECTION 9.14.     WAIVER OF BOND REQUIREMENT.

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

         SECTION 9.15.     WAIVER OF INVENTORY, ACCOUNTING AND APPRAISAL
REQUIREMENT.

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

                                   TERMINATION

         SECTION 10.1.     TERMINATION.

         (a) The respective obligations and responsibilities of the Depositor,
the Seller, the Servicer, the Document Custodian and the Trustee created hereby
(other than the obligation of the Trustee to make certain payments to
Certificateholders after the final Distribution Date and the obligation of the
Servicer to send certain notices as hereinafter set forth) shall terminate upon
notice to the Trustee of the earliest of (i) the Distribution Date on which the
Aggregate Class Principal Balance has been reduced to zero, (ii) the final
payment or other liquidation of the last Mortgage Loan in the Trust, (iii) the
optional purchase by the Servicer of the Mortgage Loans pursuant to Section
10.1(b) and (iv) the Distribution Date in August, 2028. Notwithstanding the
foregoing, in no event shall the trust created hereby continue beyond the
expiration of 21 years from the death of the last surviving descendants of
Joseph P. Kennedy, the late ambassador of the United States to the Court of St.
James's, living on the date hereof.

         (b) The Servicer shall have the right to exercise the option to effect
the transfer to it of each Mortgage Loan pursuant to Section 10.1(a) above on
any Distribution Date on or after the Distribution Date immediately prior to
which the Aggregate Loan Balance is less than five percent (5%) of the Initial
Collateral Balance by purchasing, on the next succeeding Distribution Date, all
of the outstanding Mortgage Loans at a price equal to the sum of the Aggregate
Loan Balance and accrued and unpaid interest thereon at the weighted average of
the Loan Rates through the end of the Collection Period preceding the final
Distribution Date. The exercise of such purchase right shall be conditioned upon
receipt by the Trustee of a Nondisqualification Opinion. If such right is
exercised, the Servicer shall provide to the Trustee the certification required
by Section 3.8 and, promptly following payment of the repurchase price, the
Trustee shall execute proper instruments acknowledging termination and discharge
of this Agreement in the form provided by the Servicer. Such certificate shall
be delivered by the Servicer to the Trustee in a timely manner so as to enable
the Trustee to timely notify the Holders of Certificates pursuant to Section
10.1(c).

         (c) Notice of any termination, specifying the Distribution Date (which
shall be a date that would otherwise be a Distribution Date) upon which the
Holders of Certificates may surrender their Certificates to the Trustee for
payment of the final distribution and cancellation, shall be given promptly by
the Trustee (upon receipt of written directions from the Servicer, if the
Servicer is exercising its right to retransfer the Mortgage Loans, given not
later than the first day of the month preceding the month of such final
distribution) by letter to the Holders of Certificates mailed not earlier than
the 15th day and not later than the 25th day of the month next preceding the
month of such final distribution specifying (i) the Distribution Date upon which
final distribution of the Certificates will be made, (ii) the amount of each
such final distribution and (iii) that the Record Date otherwise applicable to
such Distribution Date is not applicable. In the event written directions are
delivered by the Servicer to the Trustee as described in the preceding sentence,
the Servicer shall deposit in the Distribution Account on or before the
Distribution Date for such final distribution in immediately available funds an
amount which,



                                      115
<PAGE>   121

when added to the funds on deposit in the Distribution Account that are payable
to the Holders of Certificates, will be equal to the retransfer amount for the
Mortgage Loans computed as above provided.

         (d) Upon presentation and surrender of the Class SA, Class A and
Subordinate Certificates, the Trustee shall cause to be distributed to the
Holders thereof on the Distribution Date for such final distribution, in
proportion to the Percentage Interests of their respective Certificates and to
the extent that funds are available for such purpose, an amount equal to the
amount required to be distributed to Holders of such Certificates pursuant to
Section 5.1 for such Distribution Date.

         (e) In the event that all of the Certificateholders shall not surrender
their Certificates for final payment and cancellation on or before such final
Distribution Date, the Trustee shall promptly following such date cause all
funds in the Distribution Account not distributed in final distribution to
Certificateholders to be withdrawn therefrom and credited to the remaining
Certificateholders by depositing such funds in a separate escrow account for the
benefit of such Certificateholders and the Servicer (if the Servicer has
exercised its right to purchase the Mortgage Loans) or the Trustee (in any other
case) shall give a second written notice to the remaining Certificateholders to
surrender their Certificates for cancellation and receive the final distribution
with respect thereto. If within nine months after the second notice all the
Certificates shall not have been surrendered for cancellation, the Class R
Certificateholder shall be entitled to all unclaimed funds and other assets
which remain subject hereto and the Trustee upon transfer of such funds shall be
discharged of any responsibility for such funds and the Certificateholders shall
look to the Class R Certificateholder for payment.

         SECTION 10.2.     ADDITIONAL TERMINATION REQUIREMENTS.

         (a) In the event that the Servicer exercises its purchase option as
provided in Section 10.1, the Trust shall be terminated in accordance with the
following additional requirements, unless the Trustee has received a
Nondisqualification Opinion to the effect that the failure of the Trust to
comply with the requirements of this subsection 10.2(a) will not (A) result in
the imposition of taxes on "prohibited transactions" of the Trust, as defined in
Section 860F of the Code, or contributions to either of REMIC I or REMIC II
after the "startup day," as defined in Section 860G(d) of the Code, or (B) cause
either of REMIC I or REMIC II of the Trust to fail to qualify as a REMIC at any
time any Certificate is outstanding:

                  (i)  within ninety (90) days prior to the final Distribution
         Date set forth in the notice given by the Trustee under Section 10.1,
         the Trustee, at the direction of the Depositor, shall adopt a plan of
         complete liquidation of the Trust in the form prepared by the
         Depositor;

                  (ii) at or after the time of adoption of such a plan of
         complete liquidation and at or prior to the Distribution Date for the
         final distribution, the Trustee shall sell all of the assets of the
         Trust either to the Depositor or other purchaser of the assets of the
         Trust, as the case may be, for cash; provided, however, that in the
         event that a calendar quarter ends after the time of adoption of such a
         plan of complete liquidation but prior to the such 


                                      116
<PAGE>   122

         final Distribution Date, the Trustee shall not sell any of the assets
         of the Trust prior to the close of that calendar quarter; and

                  (iii) the Trustee shall make the distributions specified in
         subsection 10.1(d) and (e) on or before the final Distribution Date
         referred to in clause (i) above.

         (b) The Trustee hereby agrees to adopt a plan of complete liquidation
as specified in subsection 10.2(a) upon the written direction of the Depositor
and to take such other action in connection therewith as may be reasonably
requested by the Depositor.


                                   ARTICLE XI

                              REMIC ADMINISTRATION

         SECTION 11.1.     REMIC ADMINISTRATION.

         (a) It is intended that the REMIC I and REMIC II shall each constitute,
and that the affairs of the REMIC I and REMIC II shall be conducted so as to
qualify REMIC I and REMIC II as, REMICs 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) and as agent of the Tax Matters Person on behalf of each REMIC in the
Trust, and that in such capacities, it shall:

                  (i)   prepare, sign 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) and any other Tax Return required
         to be filed by each REMIC in the Trust, using a calendar year as the
         taxable year for each REMIC in the Trust;

                  (ii)  make, or cause to be made, an election, on behalf of 
         each of the REMIC I and REMIC II, to be treated as a REMIC on the 
         federal tax return of each REMIC in the Trust for its first taxable 
         year;

                  (iii) prepare and forward, or cause to be prepared and
         forwarded, to the Trustee, the Certificateholders and to the Internal
         Revenue Service and any other relevant governmental taxing authority
         all information returns or reports as and when required to be provided
         to them in accordance with the REMIC Provisions;

                  (iv)  to the extent that the affairs of the Trust are within
         its control, conduct such affairs of the Trust at all times that any
         Certificates are outstanding so as to maintain the status of each REMIC
         in the Trust as a REMIC under the REMIC Provisions and any other
         applicable federal, state and local laws, including, without
         limitation, information reports relating to "original issue discount,"
         as defined in the Code, based upon the Prepayment Assumption and
         calculated by using the issue price of the Certificates;



                                      117
<PAGE>   123

                  (v)    not knowingly or intentionally take any action or omit
         to take any action that would cause the termination of the REMIC status
         of each REMIC in the Trust;

                  (vi)   pay from the Trust the amount of any and all federal,
         state, and local taxes, imposed upon the Trustee or the
         Certificateholders in connection with the Trust or the Mortgage Loans,
         prohibited transaction taxes as defined in Section 860F of the Code
         imposed on the Trust 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). The
         Servicer shall reimburse the Trust for any taxes paid by it pursuant to
         this clause (vi) to the extent that such taxes are imposed as a result
         of the bad faith, willful misfeasance or negligence of the Servicer in
         the performance of its obligations hereunder;

                  (vii)  ensure that any such returns or reports filed on behalf
         of each REMIC in the Trust by the Trustee are properly executed by the
         appropriate person;

                  (viii) represent each REMIC in the Trust 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 each REMIC in the Trust, enter into settlement
         agreements with any government taxing agency, extend any statute of
         limitations relating to any item of the Trust and otherwise act on
         behalf of each REMIC in the Trust in relation to any tax matter
         involving the Trust at the expense of the Servicer;

                  (ix)   as provided in Section 6.2 hereof, make available
         information necessary for the computation of any tax imposed (1) on
         transferors of Residual Certificates to transferees that are not
         Permitted Transferees or (2) on pass-through entities, any interest in
         which is held by an entity which is not a Permitted Transferee. The
         Trustee covenants and agrees that it will cooperate with the Servicer
         in the foregoing matters and that it will sign, as Trustee, any and all
         tax returns required to be filed by the Trust. Notwithstanding the
         foregoing, at such time as the Trustee becomes the successor Servicer,
         the Holder of the largest Percentage Interest of each Class of Residual
         Certificates shall serve as Tax Matters Person for such Class until
         such time as an entity is appointed to succeed the Trustee as servicer;

                  (x) make available to the Internal Revenue Service and those
         Persons specified by the REMIC Provisions all information necessary to
         compute any tax imposed (A) as a result of the Transfer of an Ownership
         Interest in a Residual Certificate to any Person who is not a Permitted
         Transferee, including the information described in Treasury regulations
         sections 1.860D-1(b)(5) and 1.860E-2(a)(5) with respect to the "excess
         inclusions" of such Residual Certificate and (B) as a result of any
         regulated investment company, real estate investment trust, common
         trust fund, partnership, trust, estate or organization described in
         Section 1381 of the Code that holds an Ownership Interest in a Residual
         Certificate having as among its record holders at any time any 



                                      118
<PAGE>   124

         Person that is not a Permitted Transferee. Reasonable compensation for
         providing such information may be accepted by the Trustee; and

                  (xi) Upon filing with the Internal Revenue Service, the
         Trustee shall furnish to the Holders of the Residual Certificates the
         Form 1066 and each Form 1066Q and shall respond promptly to written
         requests made not more frequently than quarterly by any Holder of
         Residual Certificates with respect to the following matters but only to
         the extent the Trustee has the information available with respect to
         such matters:

                           (1) The original projected principal and interest
                  cash flows on the Closing Date on each class of regular and
                  residual interests created hereunder and on the Mortgage
                  Loans, based on the Prepayment Assumption;

                           (2) The projected remaining principal and interest
                  cash flows as of the end of any calendar quarter with respect
                  to each class of regular and residual interests created
                  hereunder and the Mortgage Loans, based on the Prepayment
                  Assumption;

                           (3) The Prepayment Assumption (and any multiple
                  thereof used to calculate the issue price of the Certificates)
                  and any interest rate assumptions used in determining the
                  projected principal and interest cash flows described above;

                           (4) The original issue discount (or, in the case of
                  the Mortgage Loans, market discount) or premium accrued or
                  amortized through the end of such calendar quarter with
                  respect to each class of regular or residual interests created
                  hereunder and with respect to the Mortgage Loans, together
                  with each constant yield to maturity used in computing the
                  same;

                           (5) The treatment of losses realized with respect to
                  the Mortgage Loans or the regular interests created hereunder,
                  including the timing and amount of any cancellation of
                  indebtedness income of each REMIC with respect to such regular
                  interests or bad debt deductions claims with respect to the
                  Mortgage Loans;

                           (6) The amount and timing of any non-interest
                  expenses of each REMIC; and

                           (7) Any taxes (including penalties and interest)
                  imposed on each REMIC, including, without limitation, taxes on
                  "prohibited transactions," "contribution" or "net income from
                  foreclosure property" or state or local income or franchise
                  taxes.

         SECTION 11.2.     PROHIBITED TRANSACTIONS AND ACTIVITIES.

         Subject to the provisions of Article II, neither the Trustee nor the
Servicer shall permit the sale, disposition or substitution of a Mortgage Note

                                      119
<PAGE>   125

Mortgaged Property (except in a disposition pursuant to (i) the bankruptcy or
insolvency of the REMIC I or REMIC II or (ii) the termination of the REMIC I or
REMIC II in a "qualified liquidation" as defined in Section 860F(a)(4) of the
Code), nor acquire any assets for the REMIC I or REMIC II (other than REO), nor
sell or dispose of any investments in the Accounts for gain, nor accept any
contributions to the REMIC I or REMIC II (except as contemplated by Section
4.2), unless it has received a Nondisqualification Opinion (at the expense of
the Person requesting the Trustee to take such action) to the effect that such
disposition, acquisition, substitution, or acceptance will not (a) affect
adversely the status of the REMIC I or REMIC II as a REMIC or of the
Certificates, other than the Residual Certificates, as the regular interests
therein, (b) affect the distribution of interest or principal on the
Certificates, (c) result in the encumbrance of the assets transferred or
assigned to the REMIC I or REMIC II (except pursuant to the provisions of this
Agreement) or (d) cause the REMIC I or REMIC II to be subject to a tax on
"prohibited transactions" or "prohibited contributions" pursuant to the REMIC
Provisions.

         SECTION 11.3.     INDEMNIFICATION WITH RESPECT TO CERTAIN TAXES AND
LOSS OF REMIC STATUS.

         (a) In the event that the REMIC I or REMIC II fails to qualify as a
REMIC, loses its status as a REMIC, or incurs state or local taxes, or a tax as
a result of a prohibited transaction or contribution or the receipt of "net
income from foreclosure property" subject to taxation under the REMIC Provisions
due to the willful misfeasance, bad faith or negligent performance by the
Trustee of its duties and obligations specifically set forth herein, or by
reason of the Trustee's reckless disregard of its obligations and duties
thereunder, the Trustee shall indemnify the Trust against any and all losses,
claims, damages, liabilities or expenses ("Losses") resulting therefrom;
provided, however, that the Trustee shall not be liable for any Losses
attributable to the action or inaction of the Depositor, the Servicer, the
Seller or a Holder of a Residual Certificates nor for any Losses resulting from
misinformation provided by the Depositor, the Servicer, the Seller or the Holder
of a Residual Certificates on which the Trustee has relied. The foregoing shall
not be deemed to limit or restrict the rights and remedies of successor Holders
of the Residual Certificates at law or in equity.

         (b) In the event that REMIC I or REMIC II fails to qualify as a REMIC,
loses its status as a REMIC, or incurs state or local taxes, or a tax as a
result of a prohibited transaction or contribution or the receipt of "net income
from foreclosure property" subject to taxation under the REMIC Provisions due to
the willful misfeasance, bad faith or negligent performance of the Servicer in
the performance of its duties and obligations set forth herein, or by reason of
the Servicer's reckless disregard of its obligations and duties hereunder, the
Servicer shall indemnify the Trust against any and all tax related liabilities
and expenses, including interest and penalties ("Expenses") resulting therefrom;
provided, however, that the Servicer shall not be liable for any such Expenses
attributable to the action or inaction of the Trustee, the Depositor the Seller,
or the Holder of the Residual Certificates nor for any such Expenses resulting
from misinformation provided by the Trustee, the Depositor, the Seller or a
Holder of the Residual Certificates on which the Servicer has reasonably relied.

         The foregoing shall not be deemed to limit or restrict the rights and

                            MISCELLANEOUS PROVISIONS

         SECTION 12.1.     AMENDMENT.

         This Agreement may be amended from time to time by the Depositor, the
Servicer, the Seller, the Document Custodian and the Trustee, in each case
without the consent of any of the Certificateholders (i) to cure any ambiguity,
(ii) to correct any defective provisions or to correct or supplement any
provisions herein that may be inconsistent with any other provisions herein or
the Prospectus Supplement or the Prospectus, (iii) to add to the duties of the
Depositor, the Seller, the Trustee (subject to the penultimate paragraph of this
Section 12.1) or the Servicer, (iv) to add any other provisions with respect to
matters or questions arising under this Agreement which shall not be
inconsistent with the provisions of this Agreement, (v) to add or amend any
provisions of this Agreement as required by any Rating Agency or any other
nationally recognized statistical rating agency in order to maintain or improve
any rating of the Certificates (it being understood that, after obtaining the
ratings in effect on the Closing Date, none of the Trustee, the Depositor or the
Servicer is obligated to obtain, maintain or improve any such rating), or (vi)
to add, delete or modify any provision to such extent as shall be necessary or
desirable to maintain the qualification of the REMIC I or REMIC II as a REMIC;
provided, however, that such action shall be accompanied by a
Nondisqualification Opinion.

         This Agreement also may be amended from time to time by the Depositor,
the Servicer, the Seller, the Document Custodian and the Trustee; and the
Servicer may from time to time consent to the amendment of this Agreement with
the consent of the Majority Holders 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 Certificateholders; provided,
however, that no such amendment shall (A) reduce in any manner the amount of, or
delay the timing of, payments on the Certificates without the consent of the
Holder of such Certificate, or (B) reduce the aforesaid percentage required to
consent to any such amendment, without the consent of the Holders of all
Certificates then outstanding. Prior to execution of any such amendment, the
Depositor shall furnish the Trustee with a Nondisqualification Opinion stating
whether such amendment would cause the REMIC I or REMIC II to fail to qualify as
a REMIC. An amendment made with the consent of Certificateholders and executed
in accordance with this Section 12.1 shall be permitted or authorized by this
Agreement notwithstanding that such Opinion of Counsel may conclude that such
amendment would cause the REMIC I or REMIC II to fail to qualify as a REMIC;
provided, however, that the Trustee shall not be liable to any Person for any
amendment to this Agreement permitted under the terms hereof.

         Prior to the execution of any such amendment, the Servicer shall
furnish written notification of the substance of such amendment to each Rating
Agency. In addition, promptly after the execution of any such amendment made
with the consent of the Holders of the Certificates, the Trustee shall furnish
fully executed original counterparts of the instruments effecting such amendment
to the each Holder of a Certificate.



                                      121
<PAGE>   127

         The manner of obtaining such consents and of evidencing the
authorization of the execution thereof by Certificateholders shall be subject to
such reasonable requirements as the Trustee may prescribe.

         The Trustee may, but shall not be obligated to, enter into any such
amendment which affects the Trustee's own rights, duties or immunities under
this Agreement or otherwise.

         In connection with any amendment pursuant to this Section 12.1, the
Trustee shall be entitled to receive an Opinion of Counsel to the effect that
such amendment is authorized or permitted by this Agreement.

         SECTION 12.2.     RECORDATION OF AGREEMENT.

         This Agreement is subject to recordation in all appropriate public
offices for real property records in all the counties or other comparable
jurisdictions in which any or all of the properties subject to the Mortgages are
situated, and in any other appropriate public recording office or elsewhere,
such recordation to be effected by the Servicer, but only upon direction of
Holders of a majority of the Certificates accompanied by an Opinion of Counsel
to the effect that such recordation materially and beneficially affects the
interests of Holders of Certificates. The Holders of Certificates requesting
such recordation shall bear all costs and expenses of such recordation. The
Servicer shall have no obligation to ascertain whether such recordation so
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 12.3.     LIMITATION ON RIGHTS OF CERTIFICATEHOLDERS.

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

         No Certificateholder shall have any right to vote (except as provided
in Section 12.1) or in any manner otherwise control the operation and management
of the Trust, or the obligations of the parties hereto, nor shall anything
herein set forth, or contained in the terms of the Certificates, be construed so
as to constitute the Certificateholders from time to time as partners or members
of an association; nor shall any Certificateholder be under any liability to any
third person by reason of any action taken by the parties to this Agreement
pursuant to any provision hereof.

         No Certificateholder shall have any right by virtue or by availing
itself of any provisions of this Agreement to institute any suit, action or
proceeding in equity or at law upon or under or 



                                      122
<PAGE>   128

with respect to this Agreement, unless such Holder previously shall have given
to the Trustee a written notice of default and of the continuance thereof, as
hereinbefore provided, and unless also the Holders of 25% or more of Percentage
Interests in any Class of the Certificates shall have made written request upon
the Trustee to institute such action, suit or proceeding in its own name as
Trustee hereunder and shall have offered to the Trustee such reasonable
indemnity as it may require against the costs, expenses and liabilities to be
incurred therein or thereby, and the Trustee, for 60 days after its receipt of
such notice, request and offer of indemnity, shall have neglected or refused to
institute any such action, suit or proceeding; it being understood and intended,
and being expressly covenanted by each Certificateholder with every other
Certificateholder and the Trustee, that no one or more Holders of Certificates
shall have any right in any manner whatever by virtue or by availing itself or
themselves of any provisions of this Agreement to affect, disturb or prejudice
the rights of the Holders of any other of the Certificates, or to obtain or seek
to obtain priority over or preference to any other such Holder, or to enforce
any right under this Agreement, except in the manner herein provided and for the
equal, ratable and common benefit of all Certificateholders. For the protection
and enforcement of the provisions of this Section 12.3, each and every
Certificateholder and the Trustee shall be entitled to such relief as can be
given either at law or in equity.

         SECTION 12.4.     GOVERNING LAW.

applicable.

         The Purchaser hereby acknowledges its acceptance of all right, title

         SECTION 3.1       SELLER REPRESENTATIONS AND WARRANTIES.

         The Seller represents and warrants to the Purchaser as of the Closing
Date and as of each Subsequent Transfer Date:

               (i) It is a national banking association, validly existing and
         in good standing under the laws of the United States of America and has
         the requisite power and authority to own its assets and to transact the
         business in which it is currently engaged. It is duly qualified to do
         business and is in good standing in each jurisdiction in which the
         character of the business transacted by it or properties owned or
         leased by it requires such qualification and in which the failure so to
         qualify would have a material adverse effect on (a) its business,
         properties, assets, or condition (financial or other), (b) its
         performance of its obligations under this Purchase Agreement, (c) the
         value or marketability of the Mortgage Loans and (d) the ability to
         foreclose on the related Mortgaged Properties;

              (ii) It has the power and authority to make, execute, deliver and
         perform this Purchase Agreement and all of the transactions
         contemplated under this Purchase Agreement, and has taken all necessary
         action to authorize the execution, delivery and performance of this
         Purchase Agreement. When executed and delivered, this Purchase
         Agreement will constitute its legal, valid and binding obligation
         enforceable in accordance with its terms, except as enforcement of such
         terms may be limited by bankruptcy, insolvency or similar laws
         affecting the enforcement of creditors' rights generally and by the
         availability of equitable remedies;

             (iii) It holds all necessary licenses, certificates and permits
         from all government authorities necessary for conducting its business
         as it is presently conducted. It is not required to obtain the consent
         of any other party or any consent, license, approval or authorization
         from, or registration or declaration with, any governmental authority,
         bureau or agency in connection with the execution, delivery,
         performance, validity or enforceability of this Purchase Agreement,
         except for such consents, licenses, approvals or authorizations, or
         registrations or declarations, as shall have been obtained or filed, as
         the case may be, prior to the Closing Date;

              (iv) The execution, delivery and performance of this Purchase
         Agreement by it will not conflict with or result in a breach of, or
         constitute a default under, any provision of any existing law or
         regulation or any order or decree of any court applicable to it or any
         of its properties or any provision of its Articles of Association or
         Bylaws, or constitute a 


                                       6
<PAGE>   9

         material breach of, or result in the creation or imposition of any
         lien, charge or encumbrance upon any of its properties pursuant to, any
         mortgage, indenture, contract or other agreement to which it is a party
         or by which it may be bound;

               (v) No litigation or administrative proceeding of or before any
         court, tribunal or governmental body is currently pending, or to its
         knowledge threatened, against it or any of its properties or with
         respect to this Purchase Agreement or the Certificates which in its
         opinion has a reasonable likelihood of resulting in a material adverse
         effect on the transactions contemplated by this Purchase Agreement;

              (vi) The transactions contemplated by this Purchase Agreement are
         in the ordinary course of business of the Seller; and

             (vii) The Seller is not insolvent, nor will it be made insolvent by
         the transfer of the Mortgage Loans, nor is the Seller aware of any
         pending insolvency.

                  It is understood and agreed that the representations and
         warranties set forth in this Section 3.1 shall survive delivery of the
         Mortgage Files to the Document Custodian on behalf of the Purchaser.

         SECTION 3.2       SELLER REPRESENTATIONS AND WARRANTIES RELATING TO THE
MORTGAGE LOANS.

         The Seller represents and warrants to the Purchaser that, as of the
Closing Date with respect to the Initial Mortgage Loans and as of the related
Subsequent Transfer Date with respect to the Subsequent Mortgage Loans to be
transferred on such Subsequent Transfer Date, it has made the representations
and warranties set forth in Section 2.6(a) of the Pooling and Servicing
Agreement for the benefit of the Purchaser or the Trustee as applicable. Such
representations and warranties are incorporated by reference in this Section
3.2, and the Purchaser may rely thereon as if such representations and
warranties were fully set forth herein.

         With respect to the representations and warranties set fort in this
Section 3.2 that are made to the best of the Seller's knowledge or as to which
the Seller has no knowledge, if it is discovered by the Purchaser, the Seller,
the Servicer or a Responsible Officer of the Trustee that the substance of any
such representation and warranty is inaccurate and such inaccuracy materially
and adversely affects the value of the related Mortgage Loan then
notwithstanding the Seller's lack of knowledge with respect to the substance of
such representation and warranty being inaccurate at the time the representation
or warranty was made, such inaccuracy shall be deemed a breach of the applicable
representation or warranty and with respect to any breach of such representation
or warranty or of any other representation or warranty, the Seller shall cure,
repurchase or substitute in accordance with the Pooling and Servicing Agreement.



                                       7

         It is understood and agreed that the representations and warranties set
forth in this Section 3.2 shall survive delivery of the respective Mortgage
Files to the Document Custodian on behalf of the Purchaser.

                               SELLER'S COVENANTS


         SECTION 4.1       COVENANTS OF THE SELLER.

         (a) The Seller hereby covenants that except for the transfer hereunder,
the Seller will not sell, pledge, assign or transfer to any other Person, or
grant, create, incur, assume or suffer to exist any Lien on any Mortgage Loan,
or any interest therein; the Seller will notify the Trustee, as assignee of the
Purchaser, of the existence of any Lien on any Mortgage Loan immediately upon
discovery thereof; and the Seller will defend the right, title and interest of
the Trust Fund, as assignee of the Purchaser, in, to and under the Mortgage
Loans, against all claims of third parties claiming through or under the Seller;
provided, however, that nothing in this Section 4.1 shall prevent or be deemed
to prohibit the Seller from suffering to exist upon any of the Mortgage Loans
any Liens for municipal or other local taxes and other governmental charges if
such taxes or governmental charges shall not at the time be due and payable or
if the Seller shall currently be contesting the validity thereof in good faith
by appropriate proceedings and shall have set aside on its books adequate
reserves with respect thereto.

         (b) During the period commencing on the first day of the offering of
the Offered Senior Certificates, the Class M Certificates, the Class B-1
Certificates and the Class B-2 Certificates (collectively the "Offered
Certificates") to the public and ending on the Closing Date, the Seller shall
not, without the prior written consent of First Union Capital Markets, a

other underwriters to sell mortgage pass-through securities, collateralized
mortgage obligations or similar securities representing interests in or secured
by residential mortgage loans purchased or originated by the Seller.

               INDEMNIFICATION WITH RESPECT TO THE MORTGAGE LOANS

         SECTION 6.1       INDEMNIFICATION.

         (a) The Seller agrees to indemnify and hold harmless the Purchaser,
each of its directors, each of its officers who have signed the registration
statement, and each of its directors and each person or entity who controls the
Purchaser or any such person, within the meaning of Section 15 of the Securities
Act of 1933, as amended (the "Securities Act"), against any and all losses,
claims, damages or liabilities, joint and several, to which the Purchaser, or
any such person or entity may become subject, under the Securities Act or
otherwise, and will reimburse the Purchaser and each such controlling person for
any legal or other expenses incurred by the Purchaser or such controlling person
in connection with investigating or defending any such loss, claims, damages or
liabilities insofar as such losses, claims, damages or liabilities (or actions
in respect thereof) arise out of or are based upon any untrue statement or
alleged untrue statement of any material fact contained in the Prospectus
Supplement or any amendment or supplement to the Prospectus Supplement approved
in writing by the Seller or the omission or the alleged omission to state
therein a material fact necessary in order to make the statements in the
Prospectus Supplement or any amendment or supplement to the Prospectus
Supplement approved in writing by the Seller, in the light of the circumstances
under which they were made, not misleading, but only to the extent that such
untrue statement or alleged untrue statement or omission or alleged omission
relates to the information contained in the Prospectus Supplement under the
captions: "Summary of Terms of the Offered Certificates - The Initial Mortgage
Loans," "Risk Factors" (other than " - Book-Entry System; and " - Certificate
Ratings"), "The Seller and the Servicer" and "The Mortgage Loan Pool" and the
corresponding information in the "Summary of Terms of the Offered Certificates"
(such information, the "Seller Information"). This indemnity agreement will be
in addition to any liability which the Seller may otherwise have.

         (b) The Purchaser agrees to indemnify and hold harmless the Seller
against any and all losses, claims, damages or liabilities, joint and several,
to which the Seller, or any such person or entity may become subject, under the
Securities Act or otherwise, and will reimburse the Seller for any legal or
other expenses incurred by the Seller or such controlling person in connection
with investigating or defending any such losses, claims, damages or liabilities
insofar as such losses, claims, damages or liabilities (or actions in respect
thereof) arise out of or are based upon any untrue statement or alleged untrue
statement of any material fact contained in the Prospectus Supplement or any
amendment or supplement to the Prospectus Supplement or the omission or the
alleged omission to state therein a material fact necessary in order to make the
statements in the Prospectus Supplement or any amendment or supplement to the
Prospectus Supplement, in the light of the circumstances under which they were
made, not misleading, but only to the extent that such untrue statement or
alleged untrue statement or omission or alleged omission relates to the


                                       9
<PAGE>   12

information contained in the Prospectus Supplement other than the Seller
Information. This indemnity agreement will be in addition to any liability which
the Purchaser may otherwise have.

         (c) Promptly after receipt by any indemnified party under this Article
VI of notice of any claim or the commencement of any action, such indemnified
party shall, if a claim in respect thereof is to be made against any
indemnifying party under this Article VI, notify the indemnifying party in
writing of the claim or the commencement of that action; provided, however, that
the failure to notify an indemnifying party shall not relieve it from any
liability which it may have under this Article VI except to the extent it has
been materially prejudiced by such failure and, provided further, that the
failure to notify any indemnifying party shall not relieve it from any liability
which it may have to any indemnified party otherwise than under this Article VI.

         If any such claim or action shall be brought against an indemnified
party, and it shall notify the indemnifying party thereof, the indemnifying
party shall be entitled to participate therein and, to the extent that it
wishes, jointly with any other similarly notified indemnifying party, to assume
the defense thereof with counsel reasonably satisfactory to the indemnified
party. After notice from the indemnifying party to the indemnified party of its
election to assume the defense of such claim or action, the indemnifying party
shall not be liable to the indemnified party under this Article VI for any legal
or other expenses subsequently incurred by the indemnified party in connection
with the defense thereof other than reasonable costs of investigation.

         Any indemnified party shall have the right to employ separate counsel
in any such action and to participate in the defense thereof, but the fees and
expenses of such counsel shall be at the expense of such indemnified party
unless: (i) the employment thereof has been specifically authorized by the
indemnifying party in writing; (ii) such indemnified party shall have been
advised by such counsel that there may be one or more legal defenses available
to it which are different from or additional to those available to the
indemnifying party and in the reasonable judgment of such counsel it is
advisable for such indemnified party to employ separate counsel; or (iii) the
indemnifying party has failed to assume the defense of such action and employ
counsel reasonably satisfactory to the indemnified party, in which case, if such
indemnified party notifies the indemnifying party in writing that it elects to
employ separate counsel at the expense of the indemnifying party, the
indemnifying party shall not have the right to assume the defense of such action
on behalf of such indemnified party, it being understood, however, the
indemnifying party shall not, in connection with any one such action or separate
but substantially similar or related actions in the same jurisdiction arising
out of the same general allegations or circumstances, be liable for the
reasonable fees and expenses of more than one separate firm of attorneys (in
addition to local counsel) at any time for all such indemnified parties, which
firm shall be designated in writing by the Purchaser, if the indemnified parties
under this Article VI consist of the Purchaser, or by the Seller, if the
indemnified parties under this Article VI consist of the Seller.

         Each indemnified party, as a condition of the indemnity agreements
contained in Section 6.1(a) and (b), shall use its best efforts to cooperate
with the indemnifying party in the defense of any such action or claim. No
indemnifying party shall be liable for any settlement of any such 


                                       10
<PAGE>   13

action effected without its written consent (which consent shall not be
unreasonably withheld), but if settled with its written consent or if there be a
final judgment for the plaintiff in any such action, the indemnifying party
agrees to indemnify and hold harmless any indemnified party from and against any
loss or liability by reason of such settlement or judgment.

         Notwithstanding the foregoing sentence, if at any time an indemnified
party shall have requested an indemnifying party to reimburse the indemnified
party for fees and expenses of counsel, the indemnifying party agrees that it
shall be liable for any settlement of any proceeding effected without its
written consent if (i) such settlement is entered into more than 30 days after
receipt by such indemnifying party of the aforesaid request and (ii) such
indemnifying party shall not have reimbursed the indemnified party in accordance
with such request prior to the date of such settlement.

         (d) In order to provide for just and equitable contribution in
circumstances in which the indemnity agreement provided for in this Article VI
is for any reason held to be unenforceable although applicable in accordance
with its terms, the Seller, on the one hand, and the Purchaser, on the other,
shall contribute to the aggregate losses, liabilities, claims, damages and
expenses of the nature contemplated by said indemnity agreement incurred by the
Seller and the Purchaser in such proportions as shall be appropriate to reflect
the relative benefits received by the Seller, on the one hand, and the
Purchaser, on the other, from the sale of the Mortgage Loans such that the
Purchaser is responsible for that portion represented by the percentage that the
underwriting discount with respect to the Offered Certificates (the
"Underwriting Discount") bears to the sum of the Purchase Price and the
Underwriting Discount and the Seller shall be responsible for the balance;
provided, however, that no person guilty of fraudulent misrepresentation (within
the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation. For purposes of this Section, each person, if any, who
controls the Purchaser within the meaning of Section 15 of the Securities Act
shall have the same rights to contribution as the Purchaser and each director of
the Seller, each officer of the Seller, and each person, if any, who controls
the Seller within the meaning of Section 15 of the Securities Act shall have the
same rights to contribution as the Seller. Notwithstanding anything in this
paragraph (d) to the contrary, the Purchaser shall not be required to contribute
an amount in excess of the amount of the Underwriting Discount.

         (e) The Seller agrees to indemnify and to hold each of the Purchaser,
the Trustee, each Certificateholder and the Servicer harmless against any and
all claims, losses, penalties, fines, forfeitures, legal fees and related costs,
judgments, and any other costs, fees and expenses that the Purchaser, the
Trustee and any Certificateholder may sustain in any way (i) related to the
failure of the Seller to perform its duties in compliance with the terms of this
Purchase Agreement or (ii) arising from a breach by the Seller of its
representations and warranties in Article III of this Purchase Agreement. The
Seller shall immediately notify the Purchaser, the Trustee and each
Certificateholder if a claim is made by a third party with respect to this
Purchase Agreement, the Seller shall assume the defense of any such claim and
pay all expenses in connection therewith, including reasonable counsel fees, and
promptly pay, discharge and satisfy any judgment or decree


                                       11

which may be entered against the Purchaser, the Servicer, the Seller, the
Trustee and/or Certificateholder in respect of such claim.

         SECTION 8.7       INTENTION OF THE PARTIES.

         It is the intention of the parties that (a) the Purchaser is
purchasing, and the Seller is selling, the Initial Mortgage Loans rather than
pledging the Initial Mortgage Loans to secure a loan by the Purchaser to the
Seller and (b) the Trustee will be purchasing, and the Seller will be selling,
the Subsequent Mortgage Loans rather than pledging the Subsequent Mortgage Loans
to secure a loan by the Trustee to the Seller. Accordingly, the parties hereto
each intend to treat the transaction for Federal income tax purposes and all
other purposes (y) as a sale by the Seller, and a purchase by the Purchaser, of
the Initial Mortgage Loans and (z) as a sale by the Seller, and a purchase by
the Trustee, of the Subsequent Mortgage Loans. The Purchaser will have the right
to review the Mortgage Loans and the related Mortgage Files to determine the
characteristics of the Mortgage Loans which will affect the Federal income tax
consequences of owning the Mortgage Loans and the Seller will cooperate with all
reasonable requests made by the Purchaser in the course of such review.

         SECTION 8.8       SUCCESSORS AND ASSIGNS: ASSIGNMENT OF PURCHASE 
AGREEMENT.

         The Purchase Agreement shall bind and inure to the benefit of and be
enforceable by the Seller, the Purchaser and the Trustee. The obligations of the
Seller under this Purchase Agreement cannot be assigned or delegated to a third
party without the consent of the Purchaser, which consent shall be at the
Purchaser's sole discretion, except that the Purchaser acknowledges and agrees
that the Seller may assign its obligations hereunder to any Person into which
the Seller is merged or any corporation resulting from any merger, conversion or
consolidation to which the Seller is a party or any Person succeeding to the
business of the Seller. The parties hereto acknowledge that the Purchaser is
acquiring the Mortgage Loans for the purpose of contributing them to a trust
that will issue a series of Certificates representing undivided interests in
such Mortgage Loans. As an inducement to the Purchaser to purchase the Mortgage
Loans, the Seller acknowledges and consents to the assignment by the Purchaser
to the Trustee of all of the Purchaser's rights against the Seller pursuant to
this Purchase Agreement insofar as such rights relate to Mortgage Loans
transferred to such Trustee and to the enforcement or exercise of any right or
remedy against the Seller pursuant to this Purchase Agreement by the Trustee
under the Pooling and Servicing Agreement. Such enforcement of a right or remedy
by the Trustee shall have the same force and effect as if the right or remedy
had been enforced or exercised by the Purchaser directly. The parties
acknowledge and agree that the Trustee is an intended third party beneficiary of
this Purchase Agreement (including, specifically, the indemnification provisions
of Section 6.1(e)) and that the Trustee shall be entitled to enforce the
provisions of this Purchase Agreement against the parties hereto.

         SECTION 8.9       SURVIVAL.

         The representations and warranties set forth in Article III and the
provisions of Article VI shall survive the purchase of the Mortgage Loans
hereunder.

                      [KILPATRICK STOCKTON LLP LETTERHEAD]

First Union Residential Securitization Transactions, Inc.
One First Union Center
Charlotte, North Carolina 28288-0600

     Re:  FURST Mortgage Loan Trust 1998-A, Mortgage Pass-Through Certificates,
          Series 1998-A

Ladies and Gentlemen:

     We have acted as special counsel for First Union Residential
Securitization Transactions, Inc. (the "Depositor"), a North Carolina
corporation, in connection with the purchase of certain first lien, fixed rate
mortgage loans (the "Mortgage Loans") pursuant to the Mortgage Loan Purchase
Agreement, dated as of April 1, 1998 (the "Purchase Agreement") between First
Union National Bank, as seller (the "Seller"), and the Depositor, and the sale
by the Depositor of the Mortgage Loans to FURST Mortgage Loan Trust 1998-A (the
"Trust") created by the Pooling and Servicing Agreement, dated as of April 1,
1998 (the "Pooling and Servicing Agreement") among the Seller, the Depositor,
First Union Mortgage Corporation, as servicer, and Norwest Bank Minnesota,
National Association, as trustee and document custodian (the "Trustee" and the
"Custodian"). In exchange for the Mortgage Loans, the Trust has issued to the
Depositor Mortgage Pass-Through Certificates, Series 1998-A, Class SA-1, Class
SA-2, Class SA-3, Class SA-4, Class SA-5, Class SA-X, Class A-1, Class A-2,
Class A-3, Class A-4, Class A-5, Class A-6, Class A-7, Class A-X, Class M,
Class B-1, Class B-2, Class R-I and Class R-II (collectively, the "Offered
Certificates"), and Class B-3, Class B-4 and Class B-5 (collectively, the
"Private Certificates," and together with the Offered Certificates, the
"Certificates").

The Depositor has sold the Offered Certificates to First Union Capital Markets,
a division of Wheat First Securities, Inc. ("First Union Capital Markets"), and
Donaldson, Lufkin & Jenrette Securities Corporation ("DLJ" and, together with
First Union Capital Markets, the "Underwriters") pursuant to the Underwriting
Agreement, dated April 24, 1998 (the "Underwriting Agreement") among the
Depositor, the Seller and the Underwriters.

The Certificates represent the entire undivided beneficial interest in the
assets of the Trust. The assets of the Trust will consist primarily of the
Mortgage Loans. Terms not defined herein shall have the meanings set forth in
the Pooling and Servicing Agreement.

In arriving at the opinions expressed below, we have examined such documents
and records as we have deem appropriate, including the following:

     1.   Signed copy of the Underwriting Agreement.

     2.   The registration statement (No. 333-3574) of the Depositor on form
          S-3 on file with the Securities and Exchange Commission (the
          "Commission"). Such registration statement on the date it was
          declared effective herein referred to as the "Registration Statement".

     3.   The Prospectus, dated April 24, 1998 (the "Base Prospectus"), as
          supplemented by the Prospectus Supplement dated April 24, 1998,
          relating to the Offered Certificates (the "Prospectus Supplement")
          (such Base Prospectus, as so supplemented by the Prospectus
          Supplement, the "Prospectus").

     4.   A signed copy of the Purchase Agreement.

     5.   A signed copy of the Pooling and Servicing Agreement.

     6.   Specimens of the Certificates.

As to any facts material to the following opinions which we did not
independently establish or verify, we have relied upon statements and
representations of the responsible officers and other representations of the
Depositor and of public officials and agencies.

Based upon the foregoing and consideration of such other matters as we have
deemed appropriate, we are of the opinion that the statements in the Base
Prospectus under the headings "SUMMARY OF TERMS -- Certain Federal Income Tax
Consequences" and "--ERISA Considerations," "CERTAIN LEGAL ASPECTS OF THE
MORTGAGE LOANS," "ERISA CONSIDERATIONS" and "CERTAIN FEDERAL INCOME TAX
CONSEQUENCES," and the statements in the Prospectus Supplement under the
headings "SUMMARY OF TERMS OF THE OFFERED CERTIFICATES--Certain Federal Income 
Tax Consequences" and "--ERISA Considerations," "CERTAIN LEGAL ASPECTS OF THE
MORTGAGE LOANS," "CERTAIN FEDERAL INCOME TAX CONSEQUENCES" and "ERISA 
CONSIDERATIONS," to the extent that they constitute matters of federal law or
legal conclusions with respect thereto, have been reviewed by us and are
correct in all material respects with respect to those consequences or aspects
that are discussed.
