               Fund America Investors Trust 1998-NMC1 (the "Issuer") was formed

      "Trust Agreement"), by and between the Registrant and Wilmington Trust
      Company, as owner trustee (the "Owner Trustee").

               On June 29, 1998, the Issuer issued $236,526,000 original
      principal amount of its Collateralized Mortgage Obligations, Series
      1998-NMC1, which consist of four classes of bonds (collectively, the
      "Bonds"), designated as the Class A Bonds, the Class M-1 Bonds, the Class
      M-2 Bonds and the Class M-3 Bonds, pursuant to an Indenture, dated as of

               As security for the Bonds, the Issuer pledged to the Indenture
      Trustee pursuant to the Indenture a pool of adjustable rate,
      fully-amortizing Mortgage Loans secured by first liens on one- to

      the Registrant in a privately negotiated transaction with National
      Mortgage Corporation ("NMC") pursuant to a Mortgage Loan Sale Agreement,
      dated as of June 1, 1998, between the Registrant and NMC, and subsequently

$236,526,000 (Approximate) Collateralized Mortgage Obligations, Series 1998-NMC1


                             UNDERWRITING AGREEMENT


                                                 New York, New York
                                                 As of June 24, 1998
Salomon Brothers Inc
Seven World Trade Center
New York, New York 10048

Dear Sirs:
         Fund America Investors Corporation II, a limited purpose finance
corporation (the "Company"), proposes to cause Fund America Investors Trust
1998-NMC1, a limited purpose Delaware business trust (the "Trust"), to issue and
sell to Salomon Brothers Inc (the "Underwriter"), approximately $236,526,000
aggregate principal amount of Collateralized Mortgage Obligations, Series
1998-NMC1, which will consist of four classes of bonds (collectively, the
"Bonds"), designated as Class A, Class M-1, Class M-2 and Class M-3.

         The Bonds will be issued by the Trust to be formed pursuant to a trust
agreement (the "Trust Agreement") to be entered into between the Company and
Wilmington Trust Company, as trustee (the "Owner Trustee"). The Bonds will be
issued and secured pursuant to an indenture to be dated as of the Cut-off Date
between the Trust and Norwest Bank Minnesota, National Association ("Norwest"),
as indenture trustee (the "Indenture Trustee") (the "Indenture"). The beneficial
ownership interest in the Trust will be represented by certificates (the "Trust
Certificates") which will be transferred by the Company to National Mortgage
Finance Corporation ("NMFC"), a limited purpose wholly-owned subsidiary of
National Mortgage Corporation ("National Mortgage").

         The Bonds will be secured by collateral consisting of, among other
things, adjustable rate, fully amortizing residential first mortgage loans (the
"Mortgage Loans") and related property. The Mortgage Loans will be serviced by
National Mortgage pursuant to the terms of a servicing agreement (the "Servicing
Agreement") to be entered into among National Mortgage, the Indenture Trustee
and the Owner Trustee.

         The Company will acquire all the Mortgage Loans from National Mortgage
pursuant to a mortgage loan purchase agreement between the Company and National
Mortgage (the "Mortgage Loan Purchase Agreement"); and the Company will
contribute and assign the Mortgage Loans to the Trust pursuant to a mortgage
loan contribution agreement between the Company and the Trust (the "Mortgage
Loan Contribution Agreement"). The Mortgage Loans were originated or acquired by
National Mortgage primarily through its network of brokers and correspondents.

         Certain administrative functions with respect to the Trust will be
performed on behalf of the Trust by Norwest, as manager (the "Manager"),
pursuant to a management agreement (the "Management Agreement") between the
Trust and the Manager.

         The Bonds are described more fully in Schedule I hereto and in the
Prospectus (as defined below). The Mortgage Loans will be of the type described
and will have the aggregate principal balance set forth in Schedule I. The Bonds
will consist of four classes, designated as the Class A Bonds, the Class M-1
Bonds, the Class M-2 Bonds and the Class M-3 Bonds, and will be issued in the
denominations specified in Schedule I.

         This Agreement, the Trust Agreement, the Indenture, the Servicing
Agreement, the Mortgage Loan Purchase Agreement, the Mortgage Loan Contribution
Agreement and the Management Agreement are collectively referred to herein as
the "Basic Agreements." Capitalized terms used but not defined herein shall have
the meanings assigned thereto in the Indenture.

         1.       Representations and Warranties. The Company represents and
warrants to, and agrees with, the Underwriter that:

                  (a) The Company has filed with the Securities and Exchange

         Securities Act of 1933, as amended (the "1933 Act"), which registration
         statement has become effective and copies of which have heretofore been
         delivered to you. The Company proposes to file with the Commission
         pursuant to Rule 424 under the 1933 Act a supplement to the form of
         prospectus included in such registration statement relating to the
         Bonds and the plan of distribution thereof. Such registration
         statement, as from time to time amended through the date hereof,
         including all exhibits thereto, and all documents therein incorporated

         the 1933 Act that were filed under the Securities Exchange Act of 1934,
         as amended (the "1934 Act"), on or before the effective date of such
         registration statement, each as amended at the date hereof, but
         excluding Form T-1, is hereinafter referred to as the "Registration
         Statement;" the related prospectus supplement, in the form in which it
         shall be first filed with the Commission pursuant to Rule 424 under the
         1933 Act, is hereinafter referred to as the "Prospectus Supplement;"
         and the prospectus, in the form in which it shall be first filed with
         the Commission pursuant to Rule 424 under the 1933 Act, as supplemented
         by the Prospectus Supplement, is hereinafter referred to as the
         "Prospectus". Any reference herein to the Registration Statement or the
         Prospectus shall be deemed to refer to and include the documents
         incorporated by reference therein pursuant to Item 12 of Form S-3 which
         were filed under the 1934 Act on or before the date hereof; and any
         reference herein to the terms "amend", "amendment" or "supplement" with
         respect to the Registration Statement or the Prospectus shall be deemed
         to refer to and include the filing of any document under the 1934 Act
         deemed to be incorporated by reference therein after the date hereof.
         The Company will file with the Commission within fifteen days of the
         issuance of the Bonds a current report on Form 8-K pursuant to Rule
         13a-11 under the 1934 Act (a "Current Report") to which shall be
         attached a copy of the Indenture and the Servicing Agreement as
         executed and that sets forth specific information concerning the Bonds
         and the Mortgage Loans to the extent that such information is not set
         forth in the Prospectus.

                  (b) As of the date hereof, when the Registration Statement
         became effective, when the Prospectus is first filed pursuant to Rule
         424 under the 1933 Act, when, prior to the Closing Date, any amendment

         material fact required to be stated therein or necessary to make the
         statements therein not misleading, and (iii) the Prospectus, as amended
         or supplemented as of any such time, does not and will not contain an

         therein, in the light of the circumstances under which they were made,
         not misleading; provided, however, that the Company makes no
         representations or warranties as to the information contained in or

         amendment thereof or supplement thereto in reliance upon and in
         conformity with the information furnished in writing to the Company by
         or on behalf of the Underwriter specifically for use in connection with
         the preparation of the Registration Statement and the Prospectus. For
         all purposes of this Agreement, the Company acknowledges that the
         statements set forth in the first sentence of the second to the last

         constitute the only information furnished in writing by or on behalf of
         the Underwriter for inclusion in the documents referred to in the
         immediately preceding sentence.

                  (c) As of the date hereof, when the Registration Statement
         became effective, when the Prospectus is first filed pursuant to Rule
         424 under the 1933 Act, when, prior to the Closing Date, any amendment
         to the Registration Statement becomes effective, when any supplement to
         the Prospectus is filed with the Commission, and at the Closing Date,
         there has not and will not have been (i) any request by the Commission
         for any further amendment to the Registration Statement or the
         Prospectus or for any additional information, (ii) any issuance by the
         Commission of any stop order suspending the effectiveness of the
         Registration Statement or the institution or threatening of any
         proceeding for that purpose or (iii) any notification with respect to
         the suspension of the qualification of the Bonds for sale in any
         jurisdiction or the initiation or threatening of any proceeding for
         such purpose.

                  (d) The Bonds meet required ratings criteria for registration
         under the Registration Statement. The Bonds and the Basic Agreements
         will each conform in all material respects to the description thereof

         each of the Bonds, when validly authenticated and delivered in

         accordance with the Indenture and paid for by the Underwriter in
         accordance with this Agreement, will be duly and validly issued and
         will constitute legal, valid and binding obligations of the Trust
         enforceable against the Trust in accordance with their terms except as

         qualified under the Trust Indenture Act.

                  (e) The Trust Certificates represent undivided ownership
         interests in the Trust created by the Trust Agreement. The Trust

         party has been or will be as of the Closing Date duly authorized,
         executed and delivered by the Company and constitutes, or will
         constitute as of the Closing Date, a legal, valid and binding
         obligation of the Company enforceable against the Company in accordance
         with its terms, except as enforceability may be limited by (i)
         bankruptcy, insolvency, liquidation, receivership, moratorium,
         reorganization or other similar laws affecting the enforcement of the
         rights of creditors and (ii) general principles of equity, whether
         enforcement is sought in a proceeding in equity or at law.

                  (h) As of the Closing Date, each of the Basic Agreements to
         which the Trust is a party, assuming the due execution and delivery by
         the parties thereto, will each constitute a legal, valid and binding
         obligation of the Trust, enforceable against the Trust in accordance
         with its terms, except as enforceability may be limited by (i)
         bankruptcy, insolvency, liquidation, receivership, moratorium,
         reorganization or other similar laws affecting the enforcement of the
         rights of creditors, and (ii) general principles of equity, whether

         which it is a party, nor the consummation by the Company of any of the
         transactions herein or therein contemplated, nor compliance by the
         Company with the provisions hereof or thereof, will conflict with or
         result in a breach of any term or provision of the Certificate of
         Incorporation or by-laws of the Company, or conflict with, result in a
         breach, violation or acceleration of or constitute a default under, the
         terms of any indenture or other agreement or instrument to which the
         Company is a party or by which the Company is bound, or any statute,
         order or regulation applicable to the Company, of any court, regulatory
         body, administrative agency or governmental body having jurisdiction
         over the Company. The Company is not a party to, bound by or in breach
         or violation of any indenture or other agreement or instrument, or
         subject to or in violation of any statute, order or regulation of any
         court, regulatory body, administrative agency or governmental body
         having jurisdiction over it, which materially and adversely affects, or

         clear of any lien, mortgage, pledge, charge, encumbrance, adverse claim
         or other security interest other than the Permitted Encumbrances
         (collectively, "Liens"), and will not have assigned to any Person other
         than the Trust or the Indenture Trustee any of its right, title or
         interest in such Mortgage Loans.

                  (q) Any taxes, fees and other governmental charges in
         connection with the execution, delivery and issuance of the Basic
         Agreements, the Trust Certificates and the Bonds have been or will be

         authorities or permits issued by the appropriate state, federal or
         foreign regulatory agencies or bodies necessary to conduct the business
         now operated by it and as described in the Prospectus, and the Company
         has received no notice of proceedings relating to the revocation or
         modification of any such license, certificate, authority or permit
         which singly or in the aggregate, if the subject of an unfavorable
         decision, ruling or finding, would materially and adversely affect the
         conduct of the business, operations, financial condition or income of
         the Company.

                  (s) Neither the Company nor the Trust is, and, after giving
         effect to the issuance of the Trust Certificates or the offering and
         sale of the Bonds, will be, an "investment company" or an entity
         "controlled" by an "investment company," as such terms are defined in

         registered or is required to be registered under the 1940 Act.

                  (t) [Intentionally Omitted].

                  (u) The transfer of the Trust Certificates to NMFC does not
         require registration under the 1933 Act or any state securities or blue
         sky laws.

         the Trust Indenture Act.

                  [(w) The Indenture has been duly qualified under the Trust
         Indenture Act.]

         Any certificate signed by an officer of the Company and delivered to
the Underwriter or counsel for the Underwriter in connection with the offering
of the Bonds shall be deemed a representation and warranty as to the matters
covered thereby to the Underwriter.

         2.       Purchase and Sale. Subject to the terms and conditions and in
reliance upon the representations and warranties herein set forth, the Company

         3.       Delivery and Payment. Delivery of and payment for the Bonds
shall be made at the office, on the date and at the time specified in Schedule I
hereto, or such later date and time not later than ten (10) Business Days after
such date and time specified in Schedule I hereto as shall be agreed upon by the
Company and the Underwriter (such date and time of delivery of, and payment for,
the Bonds, the "Closing Date"). Delivery of the Bonds shall be made to the
Underwriter or their designees against payment by the Underwriter of the
purchase price therefor to or upon the order of the Company by delivery of
immediately available funds. The Bonds shall be registered in such names and in
such denominations as the Underwriter may have requested in writing not less
than three (3) full Business Days prior to the Closing Date.

         The Company agrees to have the Bonds available for inspection, checking
and packaging in New York, New York, not later than 10:00 a.m. New York time on
the Business Day prior to the Closing Date.

         4.       Offering by the Underwriter. It is understood that the
Underwriter proposes to offer the Bonds for sale as set forth in the Prospectus.

         5.       Agreements. The Company agrees with the Underwriter that:

                  (a) The Company will, prior to the termination of the offering
         of the Bonds, promptly advise the Underwriter (i) when any amendment to
         the Registration Statement has become effective or any revision of or
         supplement to the Prospectus has been so filed, (ii) of any request by
         the Commission for any amendment to the Registration Statement or the
         Prospectus or for any additional information, (iii) of the issuance by
         the Commission of any stop order suspending the effectiveness of the
         Registration Statement or the institution or threatening of any
         proceeding for that purpose, and (iv) of the receipt by the Company of
         any notification with respect to the suspension of the qualification of
         the Bonds for sale in any jurisdiction or the initiation or threatening
         of any proceeding for such purpose. The Company will use its best
         efforts to prevent the issuance of any such stop order and, if issued,
         to obtain as soon as possible the withdrawal thereof. The Company will
         not file any amendment to the Registration Statement or any revision of
         or supplement to the Prospectus (including the supplement relating to
         the Bonds included in the Prospectus) prior to the termination of the
         offering of the Bonds unless the Company has furnished to the
         Underwriter a copy for its review and will not file such proposed
         amendment or supplement to which any Underwriter reasonably objects.
         Subject to the foregoing sentence, the Company will cause the
         Prospectus to be filed with the Commission pursuant to Rule 424 under
         the 1933 Act by means reasonably calculated to result in a timely
         filing with the Commission pursuant to Rule 424 and promptly will
         advise the Underwriter when the Prospectus has been so filed.

                  (b) If, at any time when a prospectus relating to the Bonds is
         required to be delivered under the 1933 Act (i) any event occurs as a
         result of which the Prospectus as then amended or supplemented would
         include an untrue statement of a material fact or 



                                      -7-
<PAGE>   8

         omit to state a material fact necessary in order to make the statements
         therein, in the light of the circumstances existing at the time it is
         delivered to a purchaser, not misleading, or (ii) it shall be necessary
         to revise, amend or supplement the Prospectus to comply with the 1933
         Act or the rules and regulations of the Commission thereunder, the
         Company promptly will notify the Underwriter and promptly will prepare
         and file with the Commission, subject to subsection (a) of this Section
         5, a revision, amendment or supplement that will correct such untrue
         statement or omission or effect such compliance and, if such amendment
         or supplement is required to be contained in a post-effective amendment
         to the Registration Statement, will use its best efforts to cause such
         amendment to the Registration Statement to be declared effective as
         soon as possible.

                  (c) The Company will (i) furnish to the Underwriter and
         counsel for the Underwriter, without charge, signed copies of the
         Registration Statement including exhibits thereto and each amendment
         thereto that became effective on or prior to the Closing Date and, so
         long as delivery of a prospectus relating to the Bonds is required
         under the 1933 Act, as many copies of the Prospectus and any revisions
         thereof or amendments or supplements thereto as may be reasonably
         requested, and (ii) file promptly all reports and any definitive proxy
         or information statements required to be filed by the Company with the
         Commission pursuant to Section 13(a), 13(c), 14 or 15(d) of the 1934
         Act subsequent to the date of the Prospectus and for so long as the
         delivery of a prospectus is required under the 1933 Act in connection
         with the offering or sale of the Bonds.

                  (d) The Company will pay or cause to be paid all expenses
         incidental to the performance of its obligations under this Agreement
         and the Basic Agreements, including but not limited to: (i) the fees
         and disbursements of counsel to the Company, (ii) expenses of printing
         the Prospectus, (iii) any fees charged by the Rating Agencies (as
         hereinafter defined) for rating the Bonds, (iv) accounting fees and
         disbursements, (v) the costs and expenses in connection with the
         qualification or exemption of the Bonds under state securities or blue
         sky laws, including filing fees and reasonable fees and disbursements
         of counsel in connection with the preparation of any blue sky survey
         and in connection with any determination of the eligibility of the
         Bonds for investment by institutional investors and the preparation of
         any legal investment survey, and (vi) the fees and expenses of the
         Owner Trustee and the Indenture Trustee and any agent of the Owner
         Trustee and Indenture Trustee and the fees and disbursements of counsel
         for the Owner Trustee and the Indenture Trustee in connection with the
         Trust Agreement, the Servicing Agreement, the Indenture and the Bonds.
         It is understood that, except as provided in this subsection (d) and in
         Sections 7 and 11 hereof, the Underwriter will pay all of its own
         expenses, including the fees of any counsel to the Underwriter, any
         transfer taxes on resale of any of the Bonds by the Underwriter and
         advertising expenses connected with any offers of the Bonds that the
         Underwriter may make.

                  (e) So long as any Bonds are outstanding, the Company will
         cause the Servicer to furnish to the Underwriter, as soon as available,
         a copy of (i) the annual statement of compliance delivered by the
         Servicer to the Indenture Trustee pursuant to the Servicing Agreement,
         (ii) the annual independent public accountants' report furnished



                                      -8-
<PAGE>   9

         to the Indenture Trustee pursuant to the Servicing Agreement, (iii)
         each report of the Company or the Trust regarding the Bonds filed with
         the Commission under the 1934 Act or mailed to the holders of the
         Bonds, and (iv) from time to time, such other information concerning
         the Bonds as the Underwriter may reasonably request and which may be
         furnished by the Company, the Servicer or the Indenture Trustee without
         undue expense and without violation of applicable law.

                  (f) The Company will endeavor, in cooperation with the
         Underwriter and the Underwriter's counsel, to qualify the Bonds for
         offering and sale under the applicable securities and blue sky laws of
         such jurisdictions as the Underwriter may reasonably designate, and
         will maintain such qualifications in effect for a period of not less
         than one year after the date hereof, unless the offering and sale of
         the Bonds is exempt from such qualification under the Secondary
         Mortgage Market Enhancement Act of 1984, and will cooperate with the
         Underwriter and its counsel to determine the eligibility of the Bonds
         for investment by institutional investors in such jurisdictions. The
         Company will, at the Underwriter's request or the request of the
         Underwriter's counsel, file such statements and reports as may be
         required by the laws of each jurisdiction in which the Bonds have been
         qualified as above provided. Notwithstanding the foregoing, no such
         qualification shall be required in any jurisdiction where, as a result
         thereof, the Company would be subject to general service of process,
         other than by reason of the offer and sale of the Bonds, qualification
         as a foreign corporation or to taxation as a foreign corporation doing
         business in such jurisdiction.

                  (g) The Company will cause the Trust to make generally
         available to holders of the Bonds as soon as practicable, but in any
         event not later than eighteen months after the effective date of the
         Registration Statement (as defined in Rule 158(c) under the 1993 Act),
         an earnings statement of the Trust (which need not be audited)
         complying with Section 11(a) of the 1933 Act and the rules and
         regulations of the Commission thereunder (including, at the option of
         the Company, Rule 158).

         6.       Conditions to the Obligation of the Underwriter. The
obligation of the Underwriter to purchase and pay for the Bonds shall be subject
to the accuracy in all material respects of the representations and warranties
on the part of the Company contained herein as of the date hereof, as of the
date of effectiveness of any amendment to the Registration Statement prior to
the Closing Date and as of the Closing Date, to the accuracy of the statements
of the Company made in any officer's certificate pursuant to the provisions
hereof, to the performance in all material respects by the Company of its
obligations hereunder, and to the following additional conditions:

                  (a) No stop order suspending the effectiveness of the
         Registration Statement shall have been issued and no proceedings for
         that purpose shall have been instituted and be pending or shall have
         been threatened, and the Prospectus shall have been filed or mailed for
         filing with the Commission not later than required pursuant to the
         rules and regulations of the Commission.

<PAGE>   10

                  (b)      The Company shall have furnished to the Underwriter a
         certificate, dated the Closing Date, signed by the President or a vice
         president of the Company to the effect that the signer of such
         certificate has carefully examined the Registration Statement, the
         Prospectus, and this Agreement and that:

                           (i)      subsequent to the date of this Agreement and
                  the Registration Statement, there has been no material adverse
                  change in the condition, financial or otherwise, earnings,
                  business affairs, regulatory situation or business prospects
                  of the Company whether or not arising in the ordinary course
                  of business;

                           (ii)     the representations and warranties of the
                  Company in Section 1 of this Agreement are true and correct in
                  all material respects as though made at and as of the date
                  hereof;

                           (iii)    the Company has in all material respects
                  complied with all the agreements and satisfied all the
                  conditions on its part to be performed or satisfied at or
                  prior to the date hereof;

                           (iv)     no stop order suspending the effectiveness
                  of the Registration Statement has been issued and no
                  proceedings for that purpose have been instituted or
                  threatened; and

                           (v)      nothing has come to our attention that would
                  lead us to believe that the Prospectus contains any untrue
                  statement of a material fact or omits to state any material
                  fact required to be stated therein or necessary in order to
                  make the statements therein, in the light of the circumstances
                  under which they were made, not misleading.

The Company shall also have furnished to the Underwriter a certificate, dated
the Closing Date, signed by the Secretary or a vice president of the Company, in

Company, reasonably satisfactory in form and substance to counsel for the
Underwriter.

Such opinion may express its reliance as to factual matters on the

assume the due authorization, execution and delivery of the agreements,
instruments and documents referred to therein by the parties thereto other than
the Company and that such other agreements are the valid, legal and binding
obligations of such other parties. Such opinion may be qualified as an opinion

parties. Such opinion may be qualified as an opinion only on the general

         7.  Indemnification and Contribution.

         (a) The Company agrees to indemnify and hold harmless the Underwriter,
the directors, officers and employees and agents of the Underwriter, and each
person who controls the Underwriter within the meaning of either the 1933 Act or
the 1934 Act, against any and all losses, claims, damages or liabilities, joint
or several, to which they may become subject under the 1933 Act, the 1934 Act or
other federal or state statutory law or regulation, at common law 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 or alleged untrue
statement of a material fact contained in the Registration Statement or the
Prospectus or in any amendment thereto or 



                                      -13-
<PAGE>   14

supplement thereto, or arise out of or are based upon 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, and agrees to reimburse
each such indemnified party, as incurred, for any legal or other expenses
reasonably incurred by it or them in connection with investigating or defending
any such loss, claim, damage, liability or action; provided, however, that the
Company will not be liable in any such case to the extent that any such loss,
claim, damage or liability arises out of or is based upon any such untrue
statement or alleged untrue statement or omission or alleged omission made
therein in reliance upon and in conformity with written information furnished to
the Company as stated herein by or on behalf of the Underwriter specifically for
use in connection with the preparation thereof. This indemnity agreement will be
in addition to any liability which the Company may otherwise have.

         (b) The Underwriter agrees to indemnify and hold harmless the Company,
each of its directors, each of its officers who signs the Registration Statement
and each person, if any, who controls the Company within the meaning of the 1933
Act or the 1934 Act, to the same extent as the foregoing indemnity from the
Company to the Underwriter, but only with reference to written information
relating to the Underwriter furnished to the Company as herein stated by or on
behalf of the Underwriter specifically for use in the preparation of the
documents referred to in the foregoing indemnity contained in subsection (a) of
this Section 7. This indemnity agreement will be in addition to any liability
that the Underwriter may otherwise have.

         (c) Promptly after receipt by an indemnified party under this Section 7
of notice of the commencement of any action, such indemnified party shall, if a
claim in respect thereof is to be made against the indemnifying party under this
Section 7, promptly notify the indemnifying party in writing of the commencement
thereof; provided, however, that the omission so to notify the indemnifying
party will not relieve the indemnifying party from any liability which it may
have to any indemnified party under the foregoing provisions of this Section 7
unless and only to the extent that such omission results in the forfeiture of
substantive rights of the indemnifying party. If any such action is brought
against any indemnified party and that party notifies the indemnifying party of
the commencement thereof, the indemnifying party shall be entitled to
participate therein, and to the extent that it may elect by written notice
delivered to the indemnified party promptly after receiving the aforesaid notice
from such indemnified party, to assume the defense thereof, with counsel
satisfactory to such indemnified party, which counsel shall not be counsel to
the indemnifying party except with the consent of the indemnified party, and
after receipt of notice from the indemnifying party to such indemnified party of
its election so to assume the defense thereof, the indemnifying party will not
be liable to such indemnified party under this Section 7 for any legal or other
expenses subsequently incurred by such indemnified party in connection with the
defense thereof other than reasonable costs of investigation by the indemnified
party undertaken with notice to and approval by the indemnifying party. If the
indemnifying party elects not to assume the defense, all fees, disbursements and
other charges incurred by the indemnified party shall be reimbursed by the
indemnifying party promptly as they are incurred. An indemnifying party will not
be liable for any settlement of any action or claim effected without its consent
(which consent shall not be unreasonably withheld).



                                      -14-
<PAGE>   15

         (d) In order to provide for just and equitable contribution in
circumstances in which the indemnification provided for in subsections (a) and
(b) of this Section 7 is due in accordance with its terms but is for any reason
held by a court to be unavailable on grounds of policy or otherwise, the Company
and the Underwriter shall contribute to the aggregate losses, claims, damages
and liabilities (or actions in respect thereof) to which the Company and the
Underwriter may be subject in such proportion as is appropriate to reflect the
relative benefits received by the Company on the one hand and the Underwriter on
the other from the offering of the Bonds. The relative benefits received by the
Company on the one hand and the Underwriter on the other hand shall be deemed to
be in the same proportion as the total proceeds from the offering of the Bonds
(before deducting expenses) bear to the total compensation or profit (before
deducting expenses) received or realized by the Underwriter from the purchase
and resale, or underwriting, of the Bonds. If the foregoing allocation is not
permitted by applicable law, then such contribution shall be determined based on
such proportions as is appropriate to reflect not only the relative benefits as
described above but also the relative fault of the Company on the one hand and
the Underwriter on the other hand as well as any other relevant equitable
considerations. Relative fault shall be determined by reference to whether any
alleged untrue statement or omission relates to information provided by the
Company or the Underwriter. The Company and the Underwriter agrees that it would
not be just and equitable if contribution were determined by pro rata allocation
or any other method of allocation that does not take account of the equitable
considerations referred to above.

         Notwithstanding the provisions of this paragraph 7(d), no person guilty
of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933
Act) shall be entitled to contribution from any person who was not guilty of
such fraudulent misrepresentation. For purposes of this Section 7, each person,
if any, who controls the Underwriter within the meaning of the 1933 Act or the
1934 Act and each director, officer, employee or agent of the Underwriter shall
have the same rights to contribution as the Underwriter, and each person, if
any, who controls the Company within the meaning of the 1933 Act or the 1934
Act, each officer of the Company who shall have signed the Registration
Statement and each director of the Company shall have the same rights to
contribution as the Company. Any party entitled to contribution will, promptly
after receipt of notice of commencement of any action, suit or proceeding
against such party in respect of which a claim for contribution may be made
against another party or parties under this subsection (d), notify such party or
parties from whom contribution may be sought, but the omission to so notify such
party or parties shall not relieve the party or parties from whom contribution
may be sought from any other obligation it or they may have hereunder or
otherwise than under this subsection (d).

         8. Termination. This Agreement shall be subject to termination, in the
absolute discretion of the Underwriter, by notice given to the Company prior to
delivery of and payment for the Bonds, if prior to such time (i) trading in
securities generally on the New York Stock Exchange shall have been suspended or
materially limited or any setting of minimum prices for trading on such
exchange, (ii) a general moratorium on commercial banking activities in New York
shall have been declared by either Federal or New York State authorities, (iii)
there shall have occurred any outbreak or escalation of hostilities, declaration
by the United States of a national emergency or war or other calamity or crisis
the effect of which on the financial markets of the United States is such as to
make it, in the judgment of the Underwriter, impracticable or inadvisable to
market the Bonds, or (iv) any change, or any development involving a prospective



                                      -15-
<PAGE>   16

change, in or affecting particularly the business or properties of the Company,
or National Mortgage, or any of their respective affiliates, in the judgment of
the Underwriter, materially impairs the investment quality of the Bonds.

         9. Representations and Indemnities to Survive. The respective
agreements, representations, warranties, indemnities and other statements of the
Company and its respective officers and of the Underwriter set forth in or made
pursuant to this Agreement will remain in full force and effect, regardless of
any investigation made by or on behalf of the Underwriter, the Company or any of
the officers, directors or controlling persons referred to in Section 7 hereof,
and will survive delivery of and payment for the Bonds. The provisions of
Section 5(d), Section 7 and Section 11 hereof shall survive the termination or
cancellation of this Agreement.

         10. Reimbursement of Underwriter's Expenses. If the sale to the
Underwriter of the Bonds as provided for herein is not consummated for any
reason, other than by reason of a default by the Underwriter, the Underwriter's
reasonable costs and expenses shall be reimbursed by the Company.

         11. Successors. This Agreement will inure to the benefit of and be
binding upon the parties hereto and their respective successors and the
officers, directors, partners and controlling persons referred to in Section 7
hereof and their respective successors and assigns, and no other person will
have any right or obligation hereunder.

         12. Applicable Law. This Agreement will be governed by and construed in
accordance with the laws of the State of New York.

         13. Miscellaneous. This Agreement supersedes all prior or
contemporaneous agreements and understandings relating to the subject matter
hereof. Neither this Agreement nor any term hereof may be changed, waived,
discharged or terminated except by a writing signed by the party against whom
enforcement of such change, waiver, discharge or termination is sought. This
Agreement may be signed in any number of counterparts, each of which shall be
deemed an original, which taken together shall constitute one and the same
instrument.

         14. Notices. Communications hereunder will be in writing and effective
only on receipt and, if sent to the Underwriter, will be delivered to Salomon
Brothers Inc, Seven World Trade Center, New York, New York 10048, Attention:
Head: Mortgage Finance or if sent to the Company, will be delivered to Fund
America Investors Corporation II, 6400 South Fiddler's Green Circle, Suite 1200
B, Englewood, Colorado 80111, Attention: Steven B.

         15. Underwriter Representation. The Underwriter represents to the
Company that no "computational materials" or "structural term sheets" were, or
will be, distributed to investors.

         The Bonds shall be issued in the forms specified in Section 2.01.

         Subject to the provisions of Section 3.01, Section 5.07, Section 5.09
and Section 8.02(d), the principal of the Bonds shall be payable in installments
ending no later than the Final Maturity Date unless the unpaid principal of such
Bonds become due and payable at an earlier date by declaration of acceleration
or call for redemption or otherwise.

         All payments made with respect to any Bond shall be applied first to
the interest then due and payable on such Bond and then to the principal
thereof. All computations of interest accrued on any Bond shall be made on the
basis of the actual number of days elapsed in the related Interest Period and a
year assumed to consist of 360 days.

         Interest on the Bonds shall accrue at the applicable Bond Interest Rate
during each Interest Period on the Current Bond Balance of each Outstanding Bond
at the end of such Interest Period. Interest accrued during an Interest Period
shall be payable on the next following Payment Date.

         Notwithstanding any of the foregoing provisions with respect to
payments of principal of and interest on the Bonds, if the Bonds have become or

         Section 2.04.  Denominations.

         The Bonds shall be issuable only as registered Bonds in the minimum

         Section 2.05.  Execution, Authentication, Delivery and Dating.

         The Bonds shall be executed on behalf of the Issuer by an Authorized
Officer of the Owner Trustee. The signature of such Authorized Officer of the
Owner Trustee on the Bonds may be manual or by facsimile.

         Bonds bearing the manual or facsimile signature of an individual who
was at any time an Authorized Officer of the Owner Trustee shall bind the
Issuer, notwithstanding that such individual has ceased to be an Authorized
Officer of the Owner Trustee prior to the authentication and delivery of such
Bonds or was not an Authorized Officer of the Owner Trustee at the date of such
Bonds.

<PAGE>   28



         At any time and from time to time after the execution and delivery of
this Indenture, the Issuer may deliver Bonds executed on behalf of the Issuer to
the Authenticating Agent for authentication; and the Authenticating Agent shall
authenticate and deliver such Bonds as in this Indenture provided and not
otherwise.

         Each Bond authenticated on the Closing Date shall be dated the Closing
Date. All other Bonds that are authenticated after the Closing Date for any
other purpose hereunder shall be dated the date of their authentication.

         No Bond shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose, unless there appears on such Bond a
certificate of authentication substantially in the form provided for herein
executed by the Authenticating Agent by the manual signature of one of its
authorized officers or employees, and such certificate upon any Bond shall be
conclusive evidence, and the only evidence, that such Bond has been duly
authenticated and delivered hereunder.

         Section 2.06.  Registration, Registration of Transfer and Exchange.

         The Issuer shall cause to be kept a register (the "Bond Register") in
which, subject to such reasonable regulations as it may prescribe, the Issuer
shall provide for the registration of Bonds and the registration of transfers of
Bonds. The Indenture Trustee is hereby initially appointed "Bond Registrar" for
the purpose of registering Bonds and transfers of Bonds as herein provided. The
Indenture Trustee shall remain the Bond Registrar throughout the term hereof.
Upon any resignation of the Indenture Trustee, the Issuer shall promptly appoint
a successor or, in the absence of such appointment, shall assume the duties of
Bond Registrar.

         Upon surrender for registration of transfer of any Bond at the office
or agency of the Issuer to be maintained as provided in Section 3.02, the Owner
Trustee on behalf of the Issuer, shall execute, and the Authenticating Agent
shall authenticate and deliver, in the name of the designated transferee or
transferees, one or more new Bonds of any authorized denominations of the same
Class and of a like aggregate principal amount.

         At the option of the Holder, Bonds may be exchanged for other Bonds of
the same Class in any authorized denominations, and of a like aggregate initial
principal amount, upon surrender of the Bonds to be exchanged at such office or
agency. Whenever any Bonds are so surrendered for exchange, the Owner Trustee
shall execute, and the Authenticating Agent shall authenticate and deliver, the
Bonds that the Bondholder making the exchange is entitled to receive.

         All Bonds issued upon any registration of transfer or exchange of Bonds
shall be the valid obligations of the Issuer, evidencing the same debt, and
entitled to the same benefits under this Indenture, as the Bonds surrendered
upon such registration of transfer or exchange.

         Every Bond presented or surrendered for registration of transfer or
exchange shall be duly endorsed, or be accompanied by a written instrument of
transfer in form satisfactory to the Bond Registrar duly executed by the Holder
thereof or his attorney duly authorized in writing.

         No service charge shall be made for any registration of transfer or
exchange of Bonds, but the Issuer and the Bond Registrar may require payment of
a sum sufficient to cover any tax or other governmental charge as may be imposed
in connection with any registration of transfer or exchange of Bonds.

         Section 2.07.  Mutilated, Destroyed, Lost or Stolen Bonds.

         If (1) any mutilated Bond is surrendered to the Bond Registrar or the
Bond Registrar receives evidence to its satisfaction of the destruction, loss or
theft of any Bond, and (2) there is delivered to the Bond Registrar such
security or indemnity as may be required by the Bond Registrar to save each of
the Issuer and the Bond Registrar harmless, then, in the absence of notice to
the Issuer or the Bond Registrar that such Bond has been acquired by a bona fide
purchaser, the Owner Trustee shall execute and upon its request the Bond
Registrar shall authenticate and deliver, in exchange for or in lieu of any such
mutilated, destroyed, lost or stolen Bond, a new Bond or Bonds of the same
Class, tenor and aggregate initial principal amount bearing a number not
contemporaneously outstanding. If, 




                                      -22-
<PAGE>   29

after the delivery of such new Bond, a bona fide purchaser of the original Bond
in lieu of which such new Bond was issued presents for payment such original
Bond, the Issuer and the Bond Registrar shall be entitled to recover such new
Bond from the person to whom it was delivered or any person taking therefrom,
except a bona fide purchaser, and shall be entitled to recover upon the security
or indemnity provided therefor to the extent of any loss, damage, cost or
expenses incurred by the Issuer or the Bond Registrar in connection therewith.
If any such mutilated, destroyed, lost or stolen Bond shall have become or shall
be about to become due and payable, or shall have become subject to redemption
in full, instead of issuing a new Bond, the Issuer may pay such Bond without
surrender thereof, except that any mutilated Bond shall be surrendered.

         Upon the issuance of any new Bond under this Section, the Issuer or the
Bond 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
reasonable expenses (including the fees and expenses of the Indenture Trustee or
the Bond Registrar) connected therewith.

         Every new Bond issued pursuant to this Section in lieu of any
destroyed, lost or stolen Bond shall constitute an original additional
contractual obligation of the Issuer, whether or not the destroyed, lost or
stolen Bond shall be at any time enforceable by anyone, and shall be entitled to
all the benefits of this Indenture equally and proportionately with any and all
other Bonds of the same Class duly issued hereunder.

         The provisions of this Section are exclusive and shall preclude (to the
extent lawful) all other rights and remedies with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Bonds.

         Section 2.08.  Payments of Principal and Interest.

                  (a) Payments on Bonds issued as Book-Entry Bonds will be made
         by or on behalf of the Indenture Trustee to the Clearing Agency or its
         nominee. Any installment of interest or principal payable on any
         Definitive Bonds that is punctually paid or duly provided for by the
         Issuer on the applicable Payment Date shall be paid to the Person in
         whose name such Bond (or one or more Predecessor Bonds) is registered
         at the close of business on the Record Date for such Payment Date by
         either (i) check mailed to such Person's address as it appears in the
         Bond Register on such Record Date, or (ii) by wire transfer of
         immediately available funds to the account of a Bondholder, if such
         Bondholder (A) is the registered holder of Definitive Bonds having an
         initial principal amount of at least $1,000,000 and (B) has provided
         the Indenture Trustee with wiring instructions in writing by five
         Business Days prior to the related Record Date or has provided the
         Indenture Trustee with such instructions for any previous Payment Date,
         except for the final installment of principal payable with respect to
         such Bond (or the Redemption Price for any Bond called for redemption,
         if such redemption will result in payment of the then entire unpaid
         principal amount of such Bond), which shall be payable as provided in
         subsection (b) below of this Section 2.08. A fee may be charged by the
         Indenture Trustee to a Bondholder of Definitive Bonds for any payment
         made by wire transfer. Any installment of interest or principal not
         punctually paid or duly provided for shall be payable as soon as funds
         are available to the Indenture Trustee for payment thereof, or if
         Section 5.07 applies, pursuant to Section 5.07.

                  (b) All reductions in the principal amount of a Bond (or one
         or more Predecessor Bonds) effected by payments of installments of
         principal made on any Payment Date shall be binding upon all Holders of
         such Bond and of any Bond issued upon the registration of transfer
         thereof or in exchange therefor or in lieu thereof, whether or not such
         payment is noted on such Bond. The final installment of principal of
         each Bond (including the Redemption Price of any Bond called for
         optional redemption, if such optional redemption will result in payment
         of the entire unpaid principal amount of such Bond) shall be payable
         only upon presentation and surrender thereof on or after the Payment
         Date therefor at the Indenture Trustee's presenting office located
         within the United States of America pursuant to Section 3.02.

                  Whenever the Indenture Trustee expects that the entire
         remaining unpaid principal amount of any Bond will become due and
         payable on the next Payment Date other than pursuant to a redemption
         pursuant to Article X, it shall, no later than two days prior to such
         Payment Date, telecopy or hand deliver to each

         Person in whose name a Bond to be so retired is registered at the close
         of business on such otherwise applicable Record Date a notice to the

                  (i)  the Indenture Trustee expects that funds sufficient to 
         pay such final installment will be available in the Bond Account on
         such Payment Date; and

                  (ii) if such funds are available, (A) such final installment
         will be payable on such Payment Date, but only upon presentation and
         surrender of such Bond at the office or agency of the Bond Registrar
         maintained for such purpose pursuant to Section 3.02 (the address of
         which shall be set forth in such notice) and (B) no interest shall
         accrue on such Bond after such Payment Date.

                  Notices in connection with redemptions of Bonds shall be
         mailed to Bondholders in accordance with Section 10.02.

         in exchange for or in lieu of any other Bond of the same Class shall
         carry the rights to unpaid principal and interest that were carried by
         such other Bond. Any checks mailed pursuant to subsection (a) of this
         Section 2.08 and returned undelivered shall be held in accordance with
         Section 3.03.

                  (d) Each Payment Date Statement, prepared by the Indenture
         Trustee based on the Servicer Remittance Report delivered to the
         Indenture Trustee pursuant to the Servicing Agreement, shall be
         delivered by the Indenture Trustee to the Rating Agencies, the Owner
         Trustee, the Underwriter, and each Bondholder as the statement required
         pursuant to Section 8.06. Neither the Indenture Trustee nor the Paying
         Agent shall have any responsibility to recalculate, verify or recompute
         information contained in any such Servicer Remittance Report except to
         the extent necessary to satisfy all obligations under this Section
         2.08(d).

         Within 90 days after the end of each calendar year, the Indenture
         Trustee will be required to furnish to each Person who at any time
         during the calendar year was a Bondholder, if requested in writing by

         deemed to have been satisfied to the extent that substantially
         comparable information is provided pursuant to any requirements of the
         Code as are from time to time in force.

Indenture Trustee shall be affected by notice to the contrary.

         Section 2.10.  Cancellation.

         All Bonds surrendered for payment, registration of transfer, exchange
or redemption shall, if surrendered to any Person other than the Bond Registrar,
be delivered to the Bond Registrar and, except for an optional redemption
pursuant to Section 10.04, shall be promptly canceled by it. The Issuer may at
any time deliver to the Bond Registrar for cancellation any Bond previously
authenticated and delivered hereunder which the Issuer may have acquired in any
manner whatsoever, and all Bonds so delivered, except for an optional redemption
pursuant to Section 10.04, shall be promptly canceled by the Bond Registrar. No
Bonds shall be authenticated in lieu of or in exchange for any Bonds canceled as
provided in this Section, except as expressly permitted by this Indenture. All




                                      -24-

canceled Bonds held by the Bond Registrar shall be held by the Bond Registrar in
accordance with its standard retention policy, unless the Issuer shall direct by
an Issuer Order that they be destroyed or returned to it.

         Section 2.11.  Authentication and Delivery of Bonds.

         The Bonds may be executed by an Authorized Officer of the Owner Trustee
and delivered to the Authenticating Agent for authentication, and thereupon the
same shall be authenticated and delivered by the Authenticating Agent, upon
Issuer Request and upon receipt by the Authenticating Agent of all of the
following:

                  (a) An Issuer Order authorizing the execution, authentication
         and delivery of the Bonds and specifying the Classes, the Final
         Maturity Date, the principal amounts and the applicable Bond Interest
         Rates (or the manner in which such Bond Interest Rates are to be
         determined) of such Bonds to be authenticated and delivered.

         interest created by the Indenture against, any liens or other interests
         that arise by operation of law and that do not require any filing or
         similar action in order to take priority over a perfected security
         interest or (B) the priority of the security interest created by this
         Indenture with respect to any claim or lien in favor of the United
         States or any agency or instrumentality thereof (including federal tax

         Income Security Act of 1974).

         Issuer's Certificate of Trust or any indenture, mortgage, deed of trust
         or other agreement or instrument to which the Issuer is a party or by
         which it is bound, or any order of any court or administrative agency
         entered in any proceeding to which the Issuer is a party or by which it
         may be bound or to which it may be subject, and that all conditions
         precedent provided in this Indenture relating to the authentication and
         delivery of the Bonds have been complied with;

         interest or participation has been assigned, it has been released) and
         has the right to Grant each such Mortgage Loan to the Indenture
         Trustee;

                  (iii) the information set forth in the Mortgage Loan Schedule
         attached as Schedule I to this Indenture is correct;

                  (v)  as of the Closing Date, no lien in favor of the United
         States described in Section 6321 of the Code, or lien in favor of the
         Pension Benefit Guaranty Corporation described in Section 4068(a) of
         the Employee Retirement Income Security Act of 1974, as amended, has
         been filed as described in subsections 6323(f) and 6323(g) of the Code

         Section 2.12.  Book-Entry Bonds.

         The Bonds will be issued initially as one or more certificates in the
name of the Cede & Co., as nominee for the Clearing Agency maintaining
book-entry records with respect to ownership and transfer of such Bonds, and
registration of the Bonds may not be transferred by the Bond Registrar except
upon Book-Entry Termination. Until Book-Entry Termination, the Bond Registrar
shall deal with the Clearing Agency as representatives of the Beneficial Owners
of such Bonds for purposes of exercising the rights of Bondholders hereunder.
Each payment of principal of and interest on a Book-Entry Bond shall be paid to
the Clearing Agency, which shall credit the amount of such payments to the
accounts of its Clearing Agency Participants in accordance with its normal
procedures. Each Clearing Agency Participant shall be responsible for disbursing
such payments to the Beneficial Owners of the Book-Entry Bonds 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 Beneficial Owners of the
Book-Entry Bonds that it represents. All such credits and disbursements are to
be made by the Clearing Agency and the Clearing Agency Participants in
accordance with the provisions of the Bonds. None of the Indenture Trustee, the
Bond Registrar, if any, the Issuer, or any Paying Agent shall have any
responsibility therefor except as otherwise provided by applicable law. Requests
and directions from, and votes of, such representatives shall not be deemed to
be inconsistent if they are made with respect to different Beneficial Owners.

         Section 2.13.  Termination of Book Entry System.

                  (a)   The book-entry system through the Clearing Agency with
         respect to the Book-Entry Bonds may be terminated upon the happening of
         any of the following:

                  (i)   The Clearing Agency advises the Indenture Trustee that
         the Clearing Agency is no longer willing or able to discharge properly
         its responsibilities as nominee and depositary with respect to the
         Bonds or any Class of Bonds and the Indenture Trustee is unable to
         locate a qualified successor clearing agency satisfactory to the
         Issuer;

                  (ii)  The Issuer, in its sole discretion, elects to terminate
         the book-entry system by notice to the Clearing Agency and the
         Indenture Trustee with respect to the Bonds or any Class of Bonds; or



                                      -26-
<PAGE>   33

                  (iii)  After the occurrence of an Event of Default (at which
         time the Indenture Trustee shall use all reasonable efforts to promptly
         notify each Beneficial Owner through the Clearing Agency of such Event
         of Default), the Beneficial Owners of no less than 51% of the
         applicable Bond Balance of any Class of the Book-Entry Bonds advise the
         Indenture Trustee in writing, through the related Clearing Agency
         Participants and the Clearing Agency, that the continuation of a
         book-entry system through the Clearing Agency to the exclusion of any
         Definitive Bonds being issued to any Person other than the Clearing
         Agency or its nominee is no longer in the best interests of the
         Beneficial Owners of such Class of Bonds.

                  (b) Upon the occurrence of any event described in subsection
         (a) above, the Indenture Trustee shall use all reasonable efforts to
         notify all Beneficial Owners of the relevant Class of Bonds, through
         the Clearing Agency, of the occurrence of such event and of the
         availability of Definitive Bonds to Beneficial Owners requesting the
         same, in an aggregate Current Bond Balance representing the interest of
         each, making such adjustments and allowances as it may find necessary
         or appropriate as to accrued interest and previous calls for
         redemption. Definitive Bonds shall be issued only upon surrender to the
         Indenture Trustee of the global Bond of the relevant Class by the
         Clearing Agency, accompanied by registration instructions for the
         Definitive Bonds. Neither the Issuer nor the Indenture 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 issuance of the Definitive Bonds of the relevant
         Class, all references herein to obligations imposed upon or to be
         performed by the Clearing Agency shall cease to be applicable and the
         provisions relating to Definitive Bonds shall be applicable to such
         Class of Bonds.

         Section 2.14.  Interest Payments on the Bonds.

         On each Payment Date, the Bond Interest will be applied from the

                  (iv)  fourth, to pay the Bond Interest accrued on the

         (y) on which a Trigger Event is not in effect, the Holders of the
         Senior Bonds and the Mezzanine Bonds shall be entitled to receive

         Amount in the following amounts and order of priority:

         Holders of the Class A Bonds, until the Class A Bond Balance thereof
         has been reduced to zero;

                  (ii)  second, the lesser of (a) the excess of (X) the

         Holders of the Class M-1 Bonds pursuant to clause (ii) above and to the

         Section 2.17.  Payment of Prepayment Penalties to the

         The Indenture Trustee shall pay amounts received from the Servicer and
identified as prepayment penalties in the Servicer Remittance Report to the

lien of the Indenture and shall not be available to make payments on the Bonds.

                                   ARTICLE III

                                    COVENANTS

         Section 3.01.  Payment of Bonds.

         The Issuer will pay or cause to be duly and punctually paid the
principal of, and interest on, the Bonds in accordance with the terms of the
Bonds and this Indenture. The Bonds shall be non-recourse obligations of the
Issuer and shall be limited in right of payment to amounts available from the
Trust Estate as provided in this Indenture and the Issuer shall not otherwise be
liable for payments on the Bonds. No person shall be personally liable for any
amounts payable under the Bonds. If any other provision of this Indenture
conflicts or is deemed to conflict with the provisions of this Section 3.01, the
provisions of this Section 3.01 shall control.

         Section 3.02.  Maintenance of Office or Agency.

         The Issuer will cause the Bond Registrar to maintain its corporate
trust office at a location where Bonds may be surrendered for registration of
transfer or exchange, and where notices and demands to or upon the Issuer in
respect of the Bonds and this Indenture may be served.

         The Issuer may also from time to time at its own expense designate one
or more other offices or agencies within the United States of America where the
Bonds may be presented or surrendered for any or all such purposes and may from
time to time rescind such designations; provided, however, any designation of an
office or agency for payment of Bonds shall be subject to Section 3.03. The
Issuer will give prompt written notice to the Indenture Trustee of any such
designation or rescission and of any change in the location of any such other
office or agency.

         Section 3.03.  Money for Bond Payments to be Held in Trust.

         All payments of amounts due and payable with respect to any Bonds that
are to be made from amounts withdrawn from the Bond Account pursuant to Section
8.02(c) or Section 5.07 shall be made on behalf of the Issuer by the Paying
Agent, and no amounts so withdrawn from the Bond Account for payments of Bonds
shall be paid over to the Issuer under any circumstances except as provided in
this Section 3.03 or in Section 5.07 or Section 8.02.

         With respect to Definitive Bonds, if the Issuer shall have a Paying
Agent that is not also the Bond Registrar, such Bond Registrar shall furnish, no
later than the fifth calendar day after each Record Date, a list, in such form
as such Paying Agent may reasonably require, of the names and addresses of the
Holders of Bonds and of the number of Individual Bonds held by each such Holder.

         Whenever the Issuer shall have a Paying Agent other than the Indenture
Trustee, it will, on or before the Business Day next preceding each Payment Date
direct the Indenture Trustee to deposit with such Paying Agent an aggregate sum
sufficient to pay the amounts then becoming due (to the extent funds are then
available for such purpose in the Bond Account), such sum to be held in trust
for the benefit of the Persons entitled thereto. Any moneys deposited with a
Paying Agent in excess of an amount sufficient to pay the amounts then becoming
due on the Bonds with respect to which such deposit was made shall, upon Issuer
Order, be paid over by such Paying Agent to the Indenture Trustee for
application in accordance with Article VIII.



                                      -29-
<PAGE>   36

         Any Paying Agent other than the Indenture Trustee shall be appointed by
Issuer Order and at the expense of the Issuer. The Issuer shall not appoint any
Paying Agent (other than the Indenture Trustee) that is not, at the time of such
appointment, a depository institution or trust company whose obligations would
be Permitted Investments pursuant to clause (c) of the definition of the term
Permitted Investments. The Issuer will cause each Paying Agent other than the
Indenture Trustee to execute and deliver to the Indenture Trustee an instrument
in which such Paying Agent shall agree with the Indenture Trustee (and if the
Indenture Trustee acts as Paying Agent, it hereby so agrees), subject to the
provisions of this Section, that such Paying Agent will:

                  (1) allocate all sums received for payment to the Holders of
         Bonds on each Payment Date among such Holders in the proportion
         specified in the applicable Payment Date Statement, in each case to the
         extent permitted by applicable law;

                  (2) hold all sums held by it for the payment of amounts due
         with respect to the Bonds in trust for the benefit of the Persons
         entitled thereto until such sums shall be paid to such Persons or
         otherwise disposed of as herein provided and pay such sums to such
         Persons as herein provided;

                  (3) if such Paying Agent is not the Indenture Trustee,
         immediately resign as a Paying Agent and forthwith pay to the Indenture
         Trustee all sums held by it in trust for the payment of the Bonds if at
         any time the Paying Agent ceases to meet the standards set forth above
         required to be met by a Paying Agent at the time of its appointment;

                  (4) if such Paying Agent is not the Indenture Trustee, give
         the Indenture Trustee notice of any Default by the Issuer (or any other
         obligor upon the Bonds) in the making of any payment required to be
         made with respect to any Bonds for which it is acting as Paying Agent;

                  (5) if such Paying Agent is not the Indenture Trustee, at any
         time during the continuance of any such Default, upon the written
         request of the Indenture Trustee, forthwith pay to the Indenture
         Trustee all sums so held in trust by such Paying Agent; and

                  (6) comply with all requirements of the Code, and all
         regulations thereunder, with respect to withholding from any payments
         made by it on any Bonds of any applicable withholding taxes imposed
         thereon and with respect to any applicable reporting requirements in
         connection therewith; provided, however, that with respect to
         withholding and reporting requirements applicable to original issue
         discount (if any) on any of the Bonds, the Issuer has provided the
         calculations pertaining thereto to the Indenture Trustee and the Paying
         Agent.

         The Issuer may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or any other purpose, by Issuer
Order direct any Paying Agent, if other than the Indenture Trustee, to pay to
the Indenture Trustee all sums held in trust by such Paying Agent, such sums to
be held by the Indenture Trustee upon the same trusts as those upon which such
sums were held by such Paying Agent; and upon such payment by any Paying Agent
to the Indenture Trustee, such Paying Agent shall be released from all further
liability with respect to such money.

         Any money held by the Indenture Trustee or any Paying Agent in trust
for the payment of any amount due with respect to any Bond and remaining
unclaimed for two and one-half years after such amount has become due and
payable to the Holder of such Bond (or if earlier, three months before the date
on which such amount would escheat to a governmental entity under applicable
law) shall be discharged from such trust and paid to the Issuer; and the Holder
of such Bond shall thereafter, as an unsecured general creditor, look only to
the Issuer for payment thereof (but only to the extent of the amounts so paid to
the Issuer), and all liability of the Indenture Trustee or such Paying Agent
with respect to such trust money shall thereupon cease. The Indenture Trustee
may adopt and employ, at the expense of the Issuer, any reasonable means of
notification of such repayment (including, but not limited to, mailing notice of

         expected to, or fail to take any action if such failure should

                           at the expense, of the Issuer or the Servicer,

                  and the Issuer or the Servicer, in the case of clauses (B)(i),
                  (B)(ii) or (B)(iii) above, has irrevocably deposited or caused

then, upon Issuer Request, this Indenture and the lien, rights and interests
created hereby and thereby shall cease to be of further effect, and the
Indenture Trustee and each co-trustee and separate trustee, if any, then acting
as such hereunder shall, at the expense of the Issuer (or of the Servicer in the
case of a redemption by the Servicer), execute and deliver all such instruments
as may be necessary to acknowledge the satisfaction and discharge of this
Indenture and shall pay, or assign or transfer and deliver, to the Issuer or

entitled thereto, of the principal and interest for whose payment such money has
been deposited with the Indenture Trustee.

                              DEFAULTS AND REMEDIES

         Section 5.01.  Event of Default.

         "Event of Default", wherever used herein, means, with respect to Bonds
issued hereunder, any one of the following events (whatever the reason for such
Event of Default and whether it shall be voluntary or involuntary or be effected
by operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body):

                  (1) if (a) on any Payment Date, after taking into account all
         payments made in respect of the Bonds on such Payment Date, (i) the
         Bond Interest for the Most Senior Class remains unpaid, which default
         shall continue for a period of five days or (ii) the Aggregate
         Principal Balance of the Mortgage Loans is less than the Bond Balance
         of the Most Senior Class, or (b) on the applicable Stated Maturity
         Date, default in the payment in full of the Bond Balance of the Most
         Senior Class;

                  (2) if the Issuer shall breach, or default in the due
         observance of, any one or more of the covenants set forth in clauses
         (i) through (viii) of Section 3.09;

                  (3) if the Issuer shall breach, or default in the due
         observance or performance of, any other of its covenants in this
         Indenture, and such Default shall continue for a period of 30 days
         after there shall have been given, by registered or certified mail, to
         the Issuer and the Indenture Trustee by the Holders of Bonds of the
         Most Senior Class representing at least 25% of the Bond Balance of such
         Class a written notice specifying such Default and requiring it to be
         remedied and stating that such notice is a "Notice of Default"
         hereunder;

                  (4) if any representation or warranty of the Issuer made in
         this Indenture or any certificate or other writing delivered by the
         Issuer pursuant hereto or in connection herewith shall prove to be
         incorrect in any material respect as of the time when the same shall
         have been made and, within 30 days after there shall have been given,
         by registered or certified mail, written notice thereof to the Issuer
         and the Indenture Trustee by the Holders of Bonds of the Most Senior
         Class representing at least 25% of the Bond Balance of 



                                      -35-
<PAGE>   42

         such Class, the circumstance or condition in respect of which such
         representation or warranty was incorrect shall not have been eliminated
         or otherwise cured; provided, however, that in the event that there
         exists a remedy with respect to any such breach that consists of a
         purchase obligation, repurchase obligation or right to substitute under
         the Basic Documents, then such purchase obligation, repurchase
         obligation or right to substitute shall be the sole remedy with respect
         to such breach and shall not constitute an Event of Default hereunder;

                  (5) the entry of a decree or order for relief by a court
         having jurisdiction in respect of the Issuer in an involuntary case
         under the federal bankruptcy laws, as now or hereafter in effect, or
         any other present or future federal or state bankruptcy, insolvency or
         similar law, or appointing a receiver, liquidator, assignee, trustee,
         custodian, sequestrator or other similar official of the Issuer or of
         any substantial part of its property, or ordering the winding up or
         liquidation of the affairs of the Issuer and the continuance of any
         such decree or order unstayed and in effect for a period of 60
         consecutive days; or

                  (6) the commencement by the Issuer of a voluntary case under
         the federal bankruptcy laws, as now or hereafter in effect, or any
         other present or future federal or state bankruptcy, insolvency or
         similar law, or the consent by the Issuer to the appointment of or
         taking possession by a receiver, liquidator, assignee, trustee,
         custodian, sequestrator or other similar official of the Issuer or of
         any substantial part of its property or the making by the Issuer of an
         assignment for the benefit of creditors or the failure by the Issuer
         generally to pay its debts as such debts become due or the taking of
         corporate action by the Issuer in furtherance of any of the foregoing.

         The failure to pay the Interest Carry Forward Amount (except with
respect to the Most Senior Class of Bonds Outstanding) or the Available Funds
Cap Carry Over Amount with respect to any Class of Bonds on any Payment Date
will only constitute an Event of Default to the extent funds are available to
make such payment pursuant to Sections 2.14 and 2.16.

         Section 5.02.  Acceleration of Maturity; Rescission and Annulment.

         If an Event of Default occurs and is continuing, then and in every such
case, the Indenture Trustee may, and on request of the Holders of Bonds of the
Most Senior Class representing not less than 50% of the Bond Balance of the such
Class, shall, declare all the Bonds to be immediately due and payable by a
notice in writing to the Issuer (and to the Indenture Trustee if given by
Bondholders), and upon any such declaration such Bonds, in an amount equal to
the Bond Balance of such Bonds, together with accrued and unpaid interest
thereon (including the related Available Funds Cap Carry Forward Amount, if any)
to the date of such acceleration, shall become immediately due and payable.

         At any time after such a declaration of acceleration of maturity of the
Bonds has been made and before a judgment or decree for payment of the money due
has been obtained by the Indenture Trustee as hereinafter in this Article
provided the Holders of Bonds of the Most Senior Class representing more than
50% of the Bond Balance of such Class, by written notice to the Issuer and the
Indenture Trustee, may rescind and annul such declaration and its consequences
if:

                  (1) the Issuer has paid or deposited with the Indenture
         Trustee a sum sufficient to pay:

                           (A) all payments of principal of, and interest on,
                  all Bonds and all other amounts that would then be due
                  hereunder or upon such Bonds if the Event of Default giving
                  rise to such acceleration had not occurred; and

                           (B) all sums paid or advanced by the Indenture
                  Trustee hereunder and the reasonable compensation, expenses,
                  disbursements and advances of the Indenture Trustee, its
                  agents and counsel; and

<PAGE>   43

                  (2) all Events of Default, other than the nonpayment of the
         principal of Bonds that have become due solely by such acceleration,
         have been cured or waived as provided in Section 5.14.

         No such rescission shall affect any subsequent Default or impair any
right consequent thereon.

         Section 5.03.  Collection of Indebtedness and Suits for Enforcement 
by Indenture Trustee.

         Subject to the provisions of Section 3.01 and the following sentence,
if an Event of Default occurs and is continuing, the Indenture Trustee may
proceed to protect and enforce its rights and the rights of the Bondholders by
any Proceedings the Indenture Trustee deems appropriate to protect and enforce
any such rights, whether for the specific enforcement of any covenant or
agreement in this Indenture or in aid of the exercise of any power granted
herein, or enforce any other proper remedy. Any Proceedings brought by the
Indenture Trustee on behalf of the Bondholders or any Bondholder against the
Issuer shall be limited to the preservation, enforcement and foreclosure of the
liens, assignments, rights and security interests under the Indenture and no
attachment, execution or other unit or process shall be sought, issued or levied
upon any assets, properties or funds of the Issuer, other than the Trust Estate
relative to the Bonds in respect of which such Event of Default has occurred. If
there is a foreclosure of any such liens, assignments, rights and security
interests under this Indenture, by private power of sale or otherwise, no
judgment for any deficiency upon the indebtedness represented by the Bonds may
be sought or obtained by the Indenture Trustee or any Bondholder against the
Issuer. The Indenture Trustee shall be entitled to recover the costs and
expenses expended by it pursuant to this Article V including reasonable
compensation, expenses, disbursements and advances of the Indenture Trustee, its
agents and counsel.

         Section 5.04.  Remedies.

         If an Event of Default shall have occurred and be continuing and the
Bonds have been declared due and payable and such declaration and its
consequences have not been rescinded and annulled, the Indenture Trustee
(subject to Section 5.17, to the extent applicable) may, for the benefit of the
Bondholders, do one or more of the following:

                  (a) institute Proceedings for the collection of all amounts
         then payable on the Bonds, or under this Indenture, whether by
         declaration or otherwise, enforce any judgment obtained, and collect
         from the Issuer moneys adjudged due, subject in all cases to the
         provisions of Sections 3.01 and 5.03;

                  (b) in accordance with Section 5.17, sell the Trust Estate or
         any portion thereof or rights or interest therein, at one or more
         public or private Sales called and conducted in any manner permitted by
         law;

                  (c) institute Proceedings from time to time for the complete
         or partial foreclosure of this Indenture with respect to the Trust
         Estate;

                  (d) exercise any remedies of a secured party under the Uniform
         Commercial Code and take any other appropriate action to protect and
         enforce the rights and remedies of the Indenture Trustee or the Holders
         of the Bonds hereunder; and

                  (e) refrain from selling the Trust Estate and apply all
         Remittable Funds pursuant to Section 5.07.

         Section 5.05.  Indenture Trustee May File Proofs of Claim.

         In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, composition or other judicial
Proceeding relative to the Issuer or any other obligor upon any of the Bonds or
the property of the Issuer or of such other obligor or their creditors, the
Indenture Trustee (irrespective of whether the Bonds shall then be due and
payable as therein expressed or by declaration or otherwise and 



                                      -37-
<PAGE>   44

irrespective of whether the Indenture Trustee shall have made any demand on the
Issuer for the payment of any overdue principal or interest) shall, be entitled
and empowered, by intervention in such Proceeding or otherwise to:

                  (i)  file and prove a claim for the whole amount of
         principal and interest owing and unpaid in respect of the Bonds and
         file such other papers or documents as may be necessary or advisable in
         order to have the claims of the Indenture Trustee (including any claim
         for the reasonable compensation, expenses, disbursements and advances
         of the Indenture Trustee, its agents and counsel) and of the
         Bondholders allowed in such Proceeding, and

                  (ii) collect and receive any moneys or other property payable
         or deliverable on any such claims and to distribute the same; and any
         receiver, assignee, trustee, liquidator, or sequestrator (or other
         similar official) in any such Proceeding is hereby authorized by each
         Bondholder to make such payments to the Indenture Trustee and, in the
         event that the Indenture Trustee shall consent to the making of such
         payments directly to the Bondholders, to pay to the Indenture Trustee
         any amount due to it for the reasonable compensation, expenses,
         disbursements and advances of the Indenture Trustee, its agents and
         counsel.

         Nothing herein contained shall be deemed to authorize the Indenture
Trustee to authorize or consent to or accept or adopt on behalf of any
Bondholder any plan of reorganization, arrangement, adjustment or composition
affecting any of the Bonds or the rights of any Holder thereof, or to authorize
the Indenture Trustee to vote in respect of the claim of any Bondholder in any
such Proceeding.

         Section 5.06.  Indenture Trustee May Enforce Claims Without 
Possession of Bonds.

         All rights of action and claims under this Indenture or any of the
Bonds may be prosecuted and enforced by the Indenture Trustee without the
possession of any of the Bonds or the production thereof in any Proceeding
relating thereto, and any such Proceeding instituted by the Indenture Trustee
shall be brought in its own name as trustee of an express trust, and any
recovery of judgment shall be for the ratable benefit of the Holders of the
Bonds in respect of which such judgment has been recovered after payment of
amounts required to be paid pursuant to clause (i) of Section 5.07.

         Section 5.07.  Application of Money Collected.

         If the Bonds have been declared due and payable following an Event of
Default and such declaration and its consequences have not been rescinded and
annulled, any money collected by the Indenture Trustee with respect to such
Bonds pursuant to this Article or otherwise and any other monies that may then
be held or thereafter received by the Indenture Trustee as security for such
Bonds shall be applied in the following order, at the date or dates fixed by the
Indenture Trustee and, in case of the payment of the entire amount due on
account of principal of, and interest on, such Bonds, upon presentation and
surrender thereof:

                  (i)   first, to the Indenture Trustee, any unpaid Indenture
         Trustee's Fees then due and any other amounts payable and due to the
         Indenture Trustee under this Indenture, including any costs or expenses
         incurred by it in connection with the enforcement of the remedies
         provided for in this Article V;

                  (ii)  second, to the Servicer, any amounts required to pay
         the Servicer for any unpaid Monthly Servicing Fees then due and to
         reimburse the Servicer for Monthly Advances previously made by, and not
         previously reimbursed or retained by, the Services and, upon the final
         liquidation of the related Mortgage Loan or the final liquidation of
         the Trust Estate, Servicing Advances previously made by, and not
         previously reimbursed or retained by, the Servicer;

                  (iii) third, to the payment of the applicable Bond Interest

                  (iv)   fourth, to the payment of the Bond Balance of the

                  (xii)  twelfth, to the payment of the remainder, if any, to 
         the Issuer or any other Person legally entitled thereto.

         Section 5.08.  Limitation on Suits.

         No Holder of a Bond shall have any right to institute any Proceedings,
judicial or otherwise, with respect to this Indenture, or for the appointment of
a receiver or trustee, or for any other remedy hereunder, unless:

                  (1) such Holder has previously given written notice to the
         Indenture Trustee of a continuing Event of Default;

                  (2) the Holders of Bonds representing not less than 25% of the
         Bond Balance of the Most Senior Class shall have made written request
         to the Indenture Trustee to institute Proceedings in respect of such
         Event of Default in its own name as Indenture Trustee hereunder;

                  (3) such Holder or Holders have offered to the Indenture
         Trustee indemnity in full against the costs, expenses and liabilities
         to be incurred in compliance with such request;

                  (4) the Indenture Trustee for 60 days after its receipt of
         such notice, request and offer of indemnity has failed to institute any
         such Proceeding; and



                                      -39-
<PAGE>   46

                  (5) no direction inconsistent with such written request has
         been given to the Indenture Trustee during such 60-day period by the
         Holders of Bonds representing more than 50% of the Bond Balance of the
         Most Senior Class;

         it being understood and intended that no one or more Holders of Bonds
         shall have any right in any manner whatever by virtue of, or by
         availing of, any provision of this Indenture to affect, disturb or
         prejudice the rights of any other Holders of Bonds or to obtain or to
         seek to obtain priority or preference over any other Holders or to
         enforce any right under this Indenture, except in the manner herein
         provided and for the equal and ratable benefit of all the Holders of
         Bonds of the same Class.

         In the event the Indenture Trustee shall receive conflicting or
inconsistent requests and indemnity from two or more groups of Holders of Bonds,
each representing less than 50% of the Bond Balances of the Most Senior Class,
the Indenture Trustee in its sole discretion may determine what action, if any,
shall be taken notwithstanding any other provision herein to the contrary.

         Section 5.09.  Unconditional Rights of Bondholders to Receive Principal
and Interest.

         Subject to the provisions in this Indenture (including Sections 3.01
and 5.03) limiting the right to recover amounts due on a Bond to recovery from
amounts in the Trust Estate, the Holder of any Bond shall have the right, to the
extent permitted by applicable law, which right is absolute and unconditional,
to receive payment of each installment of interest on such Bond on the
respective Payment Date for such installments of interest, to receive payment of
each installment of principal of such Bond when due (or, in the case of any Bond
called for redemption, on the date fixed for such redemption) and to institute
suit for the enforcement of any such payment, and such right shall not be
impaired without the consent of such Holder.

         Section 5.10.  Restoration of Rights and Remedies.

         If the Indenture Trustee or any Bondholder has instituted any
Proceeding to enforce any right or remedy under this Indenture and such
Proceeding has been discontinued or abandoned for any reason, or has been
determined adversely to the Indenture Trustee or to such Bondholder, then and in
every such case the Issuer, the Indenture Trustee and the Bondholders shall,
subject to any determination in such Proceeding, be restored severally and
respectively to their former positions hereunder, and thereafter all rights and
remedies of the Indenture Trustee and the Bondholders shall continue as though
no such Proceeding had been instituted.

         Section 5.11.  Rights and Remedies Cumulative.

         No right or remedy herein conferred upon or reserved to the Indenture
Trustee or to the Bondholders is intended to be exclusive of any other right or
remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise. The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent the
concurrent assertion or employment of any other appropriate right or remedy.

         Section 5.12.  Delay or Omission Not Waiver.

         No delay or omission of the Indenture Trustee or of any Holder of any
Bond to exercise any right or remedy accruing upon any Event of Default shall
impair any such right or remedy or constitute a waiver of any such Event of
Default or an acquiescence therein. Every right and remedy given by this Article
or by law to the Indenture Trustee or to the Bondholders may be exercised from
time to time, and as often as may be deemed expedient, by the Indenture Trustee
or by the Bondholders, as the case may be.

         Section 5.13.  Control by Bondholders.

         The Holders of Bonds representing more than 50% of the Bond Balance of
the Most Senior Class on the applicable Record Date shall have the right to
direct the time, method and place of conducting any Proceeding for 



                                      -40-
<PAGE>   47

any remedy available to the Indenture Trustee or exercising any trust or power
conferred on the Indenture Trustee; provided that:

                  (1) such direction shall not be in conflict with any rule of
         law or with this Indenture;

                  (2) any direction to the Indenture Trustee to undertake a Sale
         of the Trust Estate shall be by the Holders of Bonds representing the
         percentage of the Bond Balance of the Most Senior Class specified in
         Section 5.17(b) (1), unless Section 5.17(b) (2) is applicable; and

                  (3) the Indenture Trustee may take any other action deemed
         proper by the Indenture Trustee that is not inconsistent with such
         direction; provided, however, that, subject to Section 6.01, the
         Indenture Trustee need not take any action that it determines might
         involve it in liability or be unjustly prejudicial to the Bondholders
         not consenting.

         Section 5.14.  Waiver of Past Defaults.

         The Holders of Bonds representing more than 50% of the Bond Balance of
the Most Senior Class on the applicable Record Date may on behalf of the Holders
of all the Bonds, waive any past Default hereunder and its consequences, except
a Default:

                  (1) in the payment of principal or any installment of interest
         on any Bond; or

                  (2) in respect of a covenant or provision hereof that under
         Section 9.02 cannot be modified or amended without the consent of the
         Holder of each Outstanding Bond affected.

         Upon any such waiver, such Default shall cease to exist, and any Event
of Default arising therefrom shall be deemed to have been cured for every
purpose of this Indenture; but no such waiver shall extend to any subsequent or
other Default or impair any right consequent thereon.

         Section 5.15.  Undertaking for Costs.

         All parties to this Indenture agree, and each Holder of any Bond by his
acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, in any suit for the enforcement of any right or remedy under
this Indenture, or in any suit against the Indenture Trustee for any action
taken, suffered or omitted by it as Indenture Trustee, the filing by any party
litigant in such suit of an undertaking to pay the costs of such suit, and that
such court may in its discretion assess reasonable costs, including reasonable
attorneys' fees, against any party litigant in such suit, having due regard to
the merits and good faith of the claims or defenses made by such party litigant;
but the provisions of this Section shall not apply to any suit instituted by the
Indenture Trustee, to any suit instituted by any Bondholder, or group of
Bondholders, holding in the aggregate Bonds representing more than 10% of the
Bond Balance of the Most Senior Class, or to any suit instituted by any
Bondholder for the enforcement of the payment of any amount due on any Bond on
or after the related Payment Date or for the enforcement of the payment of
principal of any Bond on or after the Final Maturity Date (or, in the case of
any Bond called for redemption, on or after the applicable Redemption Date).

         Section 5.16.  Waiver of Stay or Extension Laws.

         The Issuer covenants (to the extent that it may lawfully do so) that it
will not at any time insist upon, or plead, or in any manner whatsoever claim or
take the benefit or advantage of, any stay or extension of law wherever enacted,
now or at any time hereafter in force, that may affect the covenants in, or the
performance of, this Indenture; and the Issuer (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such
law, and covenants that it will not hinder, delay or impede the execution of any
power herein granted to the Indenture Trustee, but will suffer and permit the
execution of every such power as though no such law had been enacted.

         Section 5.17.  Sale of Trust Estate.

                  (a) The power to effect any sale (a "Sale") of any portion of
         the Trust Estate pursuant to Section 5.04 shall not be exhausted by any
         one or more Sales as to any portion of the Trust Estate remaining
         unsold, but shall continue unimpaired until the entire Trust Estate
         shall have been sold or all amounts payable on the Bonds and under this
         Indenture with respect thereto shall have been paid. The Indenture
         Trustee may from time to time postpone any public Sale by public
         announcement made at the time and place of such Sale.

                  (b) To the extent permitted by law, the Indenture Trustee
         shall not in any private Sale sell or otherwise dispose of the Trust
         Estate, or any portion thereof, unless:

                           (1) the Holders of Bonds representing not less than
                  50% of the Bond Balance of the Most Senior Class consent to or
                  direct the Indenture Trustee to make such Sale; or

                           (2) the proceeds of such Sale would be not less than
                  the entire amount that would be payable to the Holders of the
                  Bonds, in full payment thereof in accordance with Section
                  5.07, on the Payment Date next succeeding the date of such
                  Sale.

                  The purchase by the Indenture Trustee of all or any portion of
         the Trust Estate at a private Sale shall not be deemed a Sale or
         disposition thereof for purposes of this Section 5.17(b).

                  (c) Unless the Holders of all Outstanding Bonds have otherwise
         consented or directed the Indenture Trustee, at any public Sale of all
         or any portion of the Trust Estate at which a minimum bid equal to or
         greater than the amount described in paragraph (2) of subsection (b) of
         this Section 5.17 has not been established by the Indenture Trustee and
         no Person bids an amount equal to or greater than such amount, the
         Indenture Trustee, acting in its capacity as Indenture Trustee on
         behalf of the Bondholders, shall prevent such sale and bid an amount
         (which shall include the Indenture Trustee's right, in its capacity as
         Indenture Trustee, to credit bid) at least $1.00 more than the highest
         other bid in order to preserve the Trust Estate on behalf of the
         Bondholders.

                  (d) In connection with a Sale of all or any portion of the
         Trust Estate:

                           (1) any Holder or Holders of Bonds may bid for and
                  purchase the property offered for Sale, and upon compliance
                  with the terms of sale may hold, retain and possess and
                  dispose of such property, without further accountability, and
                  may, in paying the purchase money therefor, deliver any
                  Outstanding Bonds or claims for interest thereon in lieu of
                  cash up to the amount that shall, upon distribution of the net
                  proceeds of such Sale, be payable thereon, and such Bonds, in
                  case the amounts so payable thereon shall be less than the
                  amount due thereon, shall be returned to the Holders thereof
                  after being appropriately stamped to show such partial
                  payment;

                           (2) the Indenture Trustee may bid for and acquire the
                  property offered for Sale in connection with any public Sale
                  thereof, and, in lieu of paying cash therefor, may make
                  settlement for the purchase price by crediting the gross Sale
                  price against the sum of (A) the amount that would be payable
                  to the Holders of the Bonds as a result of such Sale in
                  accordance with Section 5.07 on the Payment Date next
                  succeeding the date of such Sale and (B) the expenses of the
                  Sale and of any Proceedings in connection therewith which are
                  reimbursable to it, without being required to produce the
                  Bonds in order to complete any such Sale or in order for the
                  net Sale price to be credited against such Bonds, and any
                  property so acquired by the Indenture Trustee shall be held
                  and dealt with by it in accordance with the provisions of this
                  Indenture;

                           (3) the Indenture Trustee shall execute and deliver
                  an appropriate instrument of conveyance transferring its
                  interest in any portion of the Trust Estate in connection with
                  a Sale thereof;

<PAGE>   49

                           (4) the Indenture Trustee is hereby irrevocably
                  appointed the agent and attorney-in-fact of the Issuer to
                  transfer and convey its interest in any portion of the Trust
                  Estate in connection with a Sale thereof, and to take all
                  action necessary to effect such Sale; and

                           (5) no purchaser or transferee at such a Sale shall
                  be bound to ascertain the Indenture Trustee's authority,
                  inquire into the satisfaction of any conditions precedent or
                  see to the application of any moneys.

         Section 5.18.  Action on Bonds.

         The Indenture Trustee's right to seek and recover judgment under this
Indenture shall not be affected by the seeking, obtaining or application of any
other relief under or with respect to this Indenture. Neither the lien of this
Indenture nor any rights or remedies of the Indenture Trustee or the Holders of
Bonds shall be impaired by the recovery of any judgment by the Indenture Trustee
against the Issuer or by the levy of any execution under such judgment upon any
portion of the Trust Estate.

         Section 5.19.  No Recourse to Other Trust Estates or Other Assets of
the Issuer.

         The Trust Estate Granted to the Indenture Trustee as security for the
Bonds serves as security only for the Bonds. Holders of the Bonds shall have no
recourse against the trust estate granted as security for any other series of
bonds issued by the Issuer, and no judgment against the Issuer for any amount
due with respect to the Bonds may be enforced against either the trust estate
securing any other series or any other assets of the Issuer, nor may any
prejudgment lien or other attachment be sought against any such other trust
estate or any other assets of the Issuer.

         Section 5.20.  Application of the Trust Indenture Act.

         Pursuant to Section 316(a) of the TIA, all provisions automatically
provided for in Section 316(a) are hereby expressly excluded.

         Section 5.21.  Appointment of New Trustee for the Mezzanine Bonds.

         Upon the occurrence of an Event of Default (unless such Event of
Default has been cured or waived as permitted herein) with respect to any Class
of Bonds, the Indenture Trustee shall resign as trustee for the Bonds other than
Bonds of the Most Senior Class. The Issuer is required in such circumstances to
appoint one or more separate trustees for the Holders of the Bonds other than
Bonds of the Most Senior Class; provided, however, that if the Issuer fails to
appoint such separate trustees within 15 days thereafter, the Indenture Trustee
shall immediately petition a court of competent jurisdiction to appoint such
separate trustee or trustees.

                                   ARTICLE VI

                              THE INDENTURE TRUSTEE

         Section 6.01.  Duties of Indenture Trustee.

                  (a) If an Event of Default has occurred and is continuing, the
         Indenture Trustee shall exercise such of the rights and powers vested
         in it by this Indenture, 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.

                  (b) Except during the continuance of an Event of Default:



                                      -43-
<PAGE>   50

                           (1) The Indenture Trustee need perform only those
         duties that are specifically set forth in this Indenture and no others
         and no implied covenants or obligations shall be read into this
         Indenture against the Indenture Trustee; and

                           (2) In the absence of bad faith on its part, the
         Indenture Trustee may request and conclusively rely, as to the truth of
         the statements and the correctness of the opinions expressed therein,
         upon certificates or opinions furnished to the Indenture Trustee and
         conforming to the requirements of this Indenture. The Indenture Trustee
         shall, however, examine such certificates and opinions to determine
         whether they conform on their face to the requirements of this
         Indenture.

                  (c) The Indenture Trustee may not be relieved from liability
         for its own negligent action, its own negligent failure to act or its
         own willful misconduct, except that:

                           (1) This paragraph does not limit the effect of 
         subsection (b) of this Section 6.01;

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

                           (3) The Indenture Trustee shall not be liable with
         respect to any action it takes or omits to take in good faith in
         accordance with a direction received by it pursuant to Section 5.13 or
         5.17 or exercising any trust or power conferred upon the Indenture
         Trustee under this Indenture.

                  (d) Except with respect to duties of the Indenture Trustee
         prescribed by the TIA, as to which this Section 6.01(d) shall not
         apply, for all purposes under this Indenture, the Indenture Trustee
         shall not be deemed to have notice or knowledge of any Event of Default
         described in Section 5.01(2), 5.01(5) or 5.01(6) or any Default
         described in Section 5.01(3) or 5.01(4) or of any event described in
         Section 3.05 unless a Responsible Officer assigned to and working in
         the Indenture Trustee's corporate trust department has actual knowledge
         thereof or unless written notice of any event that is in fact such an
         Event of Default or Default is received by the Indenture Trustee at the
         Corporate Trust Office, and such notice references the Bonds generally,
         the Issuer, the Trust Estate or this Indenture.

                  (e) No provision of this Indenture shall require the Indenture
         Trustee to expend or risk its own funds or otherwise incur any
         financial liability in the performance of any of its duties hereunder,
         or in the exercise of any of its rights or powers, if it shall have
         reasonable grounds for believing that repayment of such funds or
         adequate indemnity against such risk or liability is not reasonably
         assured to it under the Servicing Agreement or otherwise.

                  (f) Every provision of this Indenture that in any way relates
         to the Indenture Trustee is subject to the provisions of this Section.

                  (g) Notwithstanding any extinguishment of all right, title and
         interest of the Issuer in and to the Trust Estate following an Event of
         Default and a consequent declaration of acceleration of the Maturity of
         the Bonds, whether such extinguishment occurs through a Sale of the
         Trust Estate to another Person, the acquisition of the Trust Estate by
         the Indenture Trustee or otherwise, the rights, powers and duties of
         the Indenture Trustee with respect to the Trust Estate (or the proceeds
         thereof) and the Bondholders and the rights of Bondholders shall
         continue to be governed by the terms of this Indenture.

                  (h) The Indenture Trustee or any Custodian appointed pursuant
         to Section 8.13 shall at all times retain possession of the Mortgage
         Files in the State of Minnesota, except for those Mortgage Files or
         portions thereof released to the Servicer pursuant to this Indenture or
         the Servicing Agreement.

         Section 6.02.  Notice of Default.

         Within 90 days after the occurrence of any Default known to the
Indenture Trustee, the Indenture Trustee shall transmit by mail to all Holders
of Bonds notice of each such Default, unless such Default shall have been cured
or waived; provided, however, that in no event shall the Indenture Trustee
provide notice, or fail to provide notice of a Default known to the Indenture
Trustee in a manner contrary to the requirements of the Trust Indenture Act.
Concurrently with the mailing of any such notice to the Holders of the Bonds,
the Indenture Trustee shall transmit by mail a copy of such notice to the Rating
Agencies.

         Section 6.03.  Rights of Indenture Trustee.

                  (a) Except as otherwise provided in Section 6.01, the
         Indenture Trustee may rely on any document believed by it to be genuine
         and to have been signed or presented by the proper Person. The
         Indenture Trustee need not investigate any fact or matter stated in any
         such document.

                  (b) Before the Indenture Trustee acts or refrains from acting,
         it may require an Officers' Certificate or an Opinion of Counsel
         reasonably satisfactory in form and substance to the Indenture Trustee.
         The Indenture Trustee shall not be liable for any action it takes or
         omits to take in good faith in reliance on any such Officer's
         Certificate or Opinion of Counsel.

                  (c) The Indenture Trustee may act through agents and shall not
         be responsible for the misconduct or negligence of any agent appointed
         with due care.

                  (d) The Indenture Trustee shall not be liable for any action
         it takes or omits to take in good faith that it believes to be
         authorized or within its rights or powers.

         Section 6.04.  Not Responsible for Recitals or Issuance of Bonds.

         The recitals contained herein and in the Bonds, except the certificates
of authentication on the Bonds, shall be taken as the statements of the Issuer,
and the Indenture Trustee and the Authenticating Agent assume no responsibility
for their correctness. The Indenture Trustee makes no representations with
respect to the Trust Estate or as to the validity or sufficiency of this
Indenture or of the Bonds. The Indenture Trustee shall not be accountable for
the use or application by the Issuer of the Bonds or the proceeds thereof or any
money paid to the Issuer or upon Issuer Order pursuant to the provisions hereof.

         Section 6.05.  May Hold Bonds.

         The Indenture Trustee, any Agent, or any other agent of the Issuer, in
its individual or any other capacity, may become the owner or pledgee of Bonds
and, subject to Sections 6.07 and 6.13, may otherwise deal with the Issuer or
any Affiliate of the Issuer with the same rights it would have if it were not
Indenture Trustee, Agent or such other agent.

         Section 6.06.  Money Held in Trust.

         Money held by the Indenture Trustee in trust hereunder need not be
segregated from other funds except to the extent required by this Indenture or
by law. The Indenture Trustee shall be under no liability for interest on any
money received by it hereunder except as otherwise agreed with the Issuer and
except to the extent of income or other gain on investments that are obligations
of the Indenture Trustee, in its commercial capacity, and income or other gain
actually received by the Indenture Trustee on investments, which are obligations
of others.

         Section 6.07.  Eligibility; Disqualification.

         Irrespective of whether this Indenture is qualified under the TIA, this
Indenture shall always have a Indenture Trustee who satisfies the requirements
of TIA Sections 310(a)(1) and 310(a)(5). The Indenture Trustee shall always have
a combined capital and surplus as stated in Section 6.08. The Indenture Trustee
shall be subject to TIA Section 310(b).

<PAGE>   52

         Section 6.08.  Indenture Trustee's Capital and Surplus.

         The Indenture Trustee shall at all times have a combined capital and
surplus of at least $100,000,000 or shall be a member of a bank holding company
system, the aggregate combined capital and surplus of which is at least
$100,000,000 and shall at all times be rated "BBB" or better by Standard &
Poor's and by Fitch; provided, however, that the Indenture Trustee's separate
capital and surplus shall at all times be at least the amount required by TIA
Section 310(a)(2). If the Indenture Trustee publishes annual reports of
condition of the type described in TIA Section 310(a)(1), its combined capital
and surplus for purposes of this Section 6.08 shall be as set forth in the
latest such report. If at any time the Indenture Trustee shall cease to be
eligible in accordance with the provisions of this Section 6.08 and TIA Section
310(a)(2), it shall resign immediately in the manner and with the effect
hereinafter specified in this Article.

         Section 6.09.  Resignation and Removal; Appointment of Successor.

                  (a) No resignation or removal of the Indenture Trustee and no
         appointment of a successor Indenture Trustee pursuant to this Article
         shall become effective until the acceptance of appointment by the
         successor Indenture Trustee under Section 6.10.

                  (b) The Indenture Trustee may resign at any time by giving
         written notice thereof to the Issuer and each Rating Agency. If an
         instrument of acceptance by a successor Indenture Trustee shall not
         have been delivered to the Indenture Trustee within 30 days after the
         giving of such notice of resignation, the resigning Indenture Trustee
         may petition any court of competent jurisdiction for the appointment of
         a successor Indenture Trustee.

                  (c) The Indenture Trustee may be removed at any time by Act of
         the Holders representing more than 50% of the Bond Balance of the Most
         Senior Class, delivered to the Indenture Trustee and to the Issuer.

                  (d) If at any time:

                           (1) the Indenture Trustee shall have a conflicting
                  interest prohibited by Section 6.07 and shall fail to resign
                  or eliminate such conflicting interest in accordance with
                  Section 6.07 after written request therefor by the Issuer or
                  by any Bondholder; or

                           (2) the Indenture Trustee shall cease to be eligible
                  under Section 6.08 or shall become incapable of acting or
                  shall be adjudged a bankrupt or insolvent, or a receiver of
                  the Indenture Trustee or of its property shall be appointed,
                  or any public officer shall take charge or control of the
                  Indenture Trustee or of its property or affairs for the
                  purpose of rehabilitation, conservation or liquidation;

         then, in any such case, (i) the Issuer by an Issuer Order may remove
         the Indenture Trustee, and the Issuer shall join with the Indenture
         Trustee in the execution, delivery and performance of all instruments
         and agreements necessary or proper to appoint a successor Indenture
         Trustee and to vest in such successor Indenture Trustee any property,
         title, right or power deemed necessary or desirable, subject to the
         other provisions of this Indenture; provided, however, if the Issuer
         does not join in such appointment within fifteen (15) days after the
         receipt by it of a request to do so, or in case an Event of Default has
         occurred and is continuing, the Indenture Trustee may petition a court
         of competent jurisdiction to make such appointment, or (ii) subject to
         Section 5.15, and, in the case of a conflicting interest as described
         in clause (1) above, unless the Indenture Trustee's duty to resign has
         been stayed as provided in TIA Section 310(b), any Bondholder who has
         been a bona fide Holder of a Bond for at least six months may, on
         behalf of 



                                      -46-
<PAGE>   53

         himself and all others similarly situated petition any court of
         competent jurisdiction for the removal of the Indenture Trustee and the
         appointment of a successor Indenture Trustee.

                  (e) If the Indenture Trustee shall resign, be removed or
         become incapable of acting, or if a vacancy shall occur in the office
         of the Indenture Trustee for any cause, the Issuer, by an Issuer Order,
         shall promptly appoint a successor Indenture Trustee. If within one
         year after such resignation, removal or incapability or the occurrence
         of such vacancy a successor Indenture Trustee shall be appointed by Act
         of the Holders of Bonds representing more than 50% of the Bond Balance
         of the Most Senior Class delivered to the Issuer and the retiring
         Indenture Trustee, the successor Indenture Trustee so appointed shall,
         forthwith upon its acceptance of such appointment, become the successor
         Indenture Trustee and supersede the successor Indenture Trustee
         appointed by the Issuer. If no successor Indenture Trustee shall have
         been so appointed by the Issuer or Bondholders and shall have accepted
         appointment in the manner hereinafter provided, any Bondholder who has
         been a bonafide Holder of a Bond for at least six months may, on behalf
         of himself and all others similarly situated petition any court of
         competent jurisdiction for the appointment of a successor Indenture
         Trustee.

                  (f) The Issuer shall give notice of each resignation and each
         removal of the Indenture Trustee and each appointment of a successor
         Indenture Trustee to the Holders of Bonds. Each notice shall include
         the name of the successor Indenture Trustee and the address of its
         Corporate Trust Office.

         Section 6.10.  Acceptance of Appointment by Successor.

         Every successor Indenture Trustee appointed hereunder shall execute,
acknowledge and deliver to the Issuer and the retiring Indenture Trustee an
instrument accepting such appointment, and thereupon the resignation or removal
of the retiring Indenture Trustee shall become effective and such successor
Indenture Trustee, without any further act, deed or conveyance, shall become
vested with all the rights, powers, trusts and duties of the retiring Indenture
Trustee. Notwithstanding the foregoing, on request of the Issuer or the
successor Indenture Trustee, such retiring Indenture Trustee shall, upon payment
of its charges, execute and deliver an instrument transferring to such successor
Indenture Trustee all the rights, powers and trusts of the retiring Indenture
Trustee, and shall duly assign, transfer and deliver to such successor Indenture
Trustee all property and money held by such retiring Indenture Trustee
hereunder. Upon request of any such successor Indenture Trustee, the Issuer
shall execute and deliver any and all instruments for more fully and certainly
vesting in and confirming to such successor Indenture Trustee all such rights,
powers and trusts.

         No successor Indenture Trustee shall accept its appointment unless at
the time of such acceptance such successor Indenture Trustee shall be qualified
and eligible under this Article.

         Section 6.11.  Merger, Conversion, Consolidation or Succession to 
Business of Indenture Trustee.

         Any corporation into which the Indenture Trustee may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which the Indenture Trustee
shall be a party, or any corporation succeeding to all or substantially all of
the corporate trust business of the Indenture Trustee, shall be the successor of
the Indenture Trustee hereunder, provided such corporation shall be otherwise
qualified and eligible under this Article, without the execution or filing of
any paper or any further act on the part of any of the parties hereto. In case
any Bonds have been authenticated, but not delivered, by the Indenture Trustee
then in office, any successor by merger, conversion or consolidation to such
authenticating Indenture Trustee may adopt such authentication and deliver the
Bonds so authenticated with the same effect as if such successor Indenture
Trustee had authenticated such Bonds.

         Section 6.12.  Preferential Collection of Claims Against Issuer.

         The Indenture Trustee (and any co-trustee or separate trustee) shall be
subject to TIA Section 311(a), excluding any creditor relationship listed in TIA
Section 311(b), and an Indenture Trustee (and any co-trustee or separate
trustee) who has resigned or been removed shall be subject to TIA Section 311(a)
to the extent indicated.

         Section 6.13.  Co-Indenture Trustees and Separate Indenture Trustees.

         At any time or times, for the purpose of meeting the legal requirements
of the TIA or of any jurisdiction in which any of the Trust Estate may at the
time be located, the Indenture Trustee shall have power to appoint, and, upon
the written request of the Indenture Trustee or of the Holders of Bonds
representing more than 50% of the Bond Balance of the Most Senior Class with
respect to which a co-trustee or separate trustee is being appointed, the Issuer
shall for such purpose join with the Indenture Trustee in the execution,
delivery and performance of all instruments and agreements necessary or proper
to appoint, one or more Persons approved by the Indenture Trustee either to act
as co-trustee, jointly with the Indenture Trustee, of all or any part of the
Trust Estate, or to act as separate trustee of any such property, in either case
with such powers as may be provided in the instrument of appointment, and to
vest in such Person or Persons in the capacity aforesaid, any property, title,
right or power deemed necessary or desirable, subject to the other provisions of
this Section. If the Issuer does not join in such appointment within 15 days
after the receipt by it of a request to do so, or in case an Event of Default
has occurred and is continuing, the Indenture Trustee alone shall have power, or
the obligation as provided in Section 5.21, to make such appointment. All fees
and expenses of any co-trustee or separate trustee shall be payable by the
Issuer.

         Should any written instrument from the Issuer be required by any
co-trustee or separate trustee so appointed for more fully confirming to such
co-trustee or separate trustee such property, title, right or power, any and all
such instruments shall, on request, be executed, acknowledged and delivered by
the Issuer.

         Every co-trustee or separate trustee shall, to the extent permitted by
law, but to such extent only, be appointed subject to the following terms:

                  (1) The Bonds shall be authenticated and delivered and all
         rights, powers, duties and obligations hereunder in respect of the
         custody of securities, cash and other personal property held by, or
         required to be deposited or pledged with, the Indenture Trustee
         hereunder, shall be exercised, solely by the Indenture Trustee.

                  (2) The rights, powers, duties and obligations hereby
         conferred or imposed upon the Indenture Trustee in respect of any
         property covered by such appointment shall be conferred or imposed upon
         and exercised or performed by the Indenture Trustee or by the Indenture
         Trustee and such co-trustee or separate trustee jointly, as shall be
         provided in the instrument appointing such co-trustee or separate
         trustee, except to the extent that under any law of any jurisdiction in
         which any particular act is to be performed, the Indenture Trustee
         shall be incompetent or unqualified to perform such act, in which event
         such rights, powers, duties and obligations shall be exercised and
         performed by such co-trustee or separate trustee.

                  (3) The Indenture Trustee at any time, by an instrument in
         writing executed by it, with the concurrence of the Issuer evidenced by
         an Issuer Order, may accept the resignation of or remove any co-trustee
         or separate trustee appointed under this Section, and, in case an Event
         of Default has occurred and is continuing, the Indenture Trustee shall
         have power to accept the resignation of, or remove, any such co-trustee
         or separate trustee without the concurrence of the Issuer. Upon the
         written request of the Indenture Trustee, the Issuer shall join with
         the Indenture Trustee in the execution, delivery and performance of all
         instruments and agreements necessary or proper to effectuate such
         resignation or removal. A successor to any co-trustee or separate
         trustee so resigned or removed may be appointed in the manner provided
         in this Section.

                  (4) No co-trustee or separate trustee hereunder shall be
         personally liable by reason of any act or omission of the Indenture
         Trustee, or any other such trustee hereunder.

                  (5) Any Act of Bondholders delivered to the Indenture Trustee
         shall be deemed to have been delivered to each such co-trustee and
         separate trustee.

         Section 6.14.  Authenticating Agents.

         The Issuer shall appoint an Authenticating Agent with power to act on
its behalf and subject to its direction in the authentication and delivery of
the Bonds designated for such authentication by the Issuer and containing
provisions therein for such authentication (or with respect to which the Issuer
has made other arrangements, satisfactory to the Indenture Trustee and such
Authenticating Agent, for notation on the Bonds of the authority of an
Authenticating Agent appointed after the initial authentication and delivery of
such Bonds) in connection with transfers and exchanges under Section 2.06, as
fully to all intents and purposes as though the Authenticating Agent had been
expressly authorized by that Section to authenticate and deliver Bonds. For all
purposes of this Indenture (other than in connection with the authentication and
delivery of Bonds pursuant to Sections 2.05 and 2.11 in connection with their
initial issuance), the authentication and delivery of Bonds by the
Authenticating Agent pursuant to this Section shall be deemed to be the
authentication and delivery of Bonds "by the Indenture Trustee." Such
Authenticating Agent shall at all times be a Person that both meets the
requirements of Section 6.07 for the Indenture Trustee hereunder and has an
office for presentation of Bonds in the United States of America. The Indenture
Trustee shall initially be the Authenticating Agent and shall be the Bond
Registrar as provided in Section 2.06. The office from which the Indenture
Trustee shall perform its duties as Bond Registrar and Authenticating Agent
shall be the Corporate Trust Office. Any Authenticating Agent appointed pursuant
to the terms of this Section 6.14 or pursuant to the terms of any supplemental
indenture shall deliver to the Indenture Trustee as a condition precedent to the
effectiveness of such appointment an instrument accepting the trusts, duties and
responsibilities of Authenticating Agent and of Bond Registrar or co-Bond
Registrar and indemnifying the Indenture Trustee for and holding the Indenture
Trustee harmless against, any loss, liability or expense (including reasonable
attorneys' fees) incurred without negligence or bad faith on its part, arising
out of or in connection with the acceptance, administration of the trust or
exercise of authority by such Authenticating Agent, Bond Registrar or co-Bond
Registrar.

         Any corporation into which any Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, consolidation or conversion to which any Authenticating Agent
shall be a party, or any corporation succeeding to the corporate trust business
of any Authenticating Agent, shall be the successor of the Authenticating Agent
hereunder, if such successor corporation is otherwise eligible under this
Section, without the execution or filing of any further act on the part of the
parties hereto or the Authenticating Agent or such successor corporation.

         Any Authenticating Agent may at any time resign by giving written
notice of resignation to the Issuer. The Issuer may at any time terminate the
agency of any Authenticating Agent by giving written notice of termination to
such Authenticating Agent. Upon receiving such a notice of resignation or upon
such a termination, or in case at any time any Authenticating Agent shall cease
to be eligible under this Section, the Issuer shall promptly appoint a successor
Authenticating Agent, shall give written notice of such appointment to the
Indenture Trustee, and shall mail notice of such appointment to all Holders of
Bonds.

         The Indenture Trustee agrees, subject to Section 6.01(e), to pay to any
Authenticating Agent from time to time reasonable compensation for its services
and the Indenture Trustee shall be entitled to be reimbursed for such payments
pursuant to Section 6.05 of the Servicing Agreement. The provisions of Sections
2.09, 6.04 and 6.05 shall be applicable to any Authenticating Agent.

         Section 6.15.  Review of Mortgage Files.

                  (a) Initial Certification. The Indenture Trustee shall, for
         the benefit of the Bondholders, review each Mortgage File prior to the
         Closing Date to ascertain that all documents required to be included in
         the Mortgage File are included therein, and shall deliver to the
         Mortgage Loan Seller and the Servicer on the Closing Date an Initial
         Certification in the form attached hereto as Exhibit E-1 with respect
         to each Mortgage Loan to the effect that, except as specifically noted
         on a schedule of exceptions thereto, (A) all documents required to be
         contained in the Mortgage File are in its possession, (B) such
         documents have been reviewed by it and appear regular on their face and
         relate to such Mortgage Loan, and (C) based on its 



                                      -49-
<PAGE>   56

         examination and only as to the foregoing documents, the information set
         forth on the related Mortgage Loan Schedule accurately reflects
         information set forth in the Mortgage File.

                  It is understood that before making the Initial Certification,
         the Indenture Trustee shall examine the related Mortgage Loan Documents
         to confirm that:

                           (1) each Mortgage Note and Mortgage bears an original
                  signature or signatures purporting to be that of the Person or
                  Persons named as the maker and mortgagor/trustor or, if
                  photocopies are permitted, that such copies bear a
                  reproduction of such signature or signatures;

                           (2) the principal amount of the indebtedness secured
                  by the related Mortgage is identical to the original principal
                  amount of the related Mortgage Note;

                           (3) the Assignment of the related Mortgage from the
                  Mortgage Loan Seller to the Indenture Trustee is in the form
                  required pursuant to clause (e) of the definition of "Mortgage
                  Loan Documents" in the Mortgage Loan Sale Agreement, and bears
                  an original signature of the Mortgage Loan Seller and any
                  other necessary party (or signatures purporting to be that of
                  the Mortgage Loan Seller and any such other party) or, if
                  photocopies are permitted, that such copies bear a
                  reproduction of such signature or signatures;

                           (4) if intervening Assignments are included in the
                  Mortgage File, each such intervening Assignment bears an
                  original signature of the related mortgagee and/or the
                  assignee (and any other necessary party) (or signatures
                  purporting to be that of each such party) or, if photocopies
                  are permitted, that such copies bear a reproduction of such
                  signature or signatures; and

                           (5) if any of a title insurance policy, certificate
                  of title insurance or a written commitment to issue a title
                  insurance policy is delivered, such policy, certificate or
                  written commitment is for an amount not less than the original
                  principal amount of the related Mortgage Note.

                  (b) Final Certification. On or before one year following the
         Closing Date, the Indenture Trustee shall deliver to the Mortgage Loan
         Seller and the Servicer a Final Certification in the form attached
         hereto as Exhibit E-2 evidencing the completeness of the Mortgage File
         for each Mortgage Loan, except as specifically noted on a schedule of
         exceptions thereto.

                  (c) Certification Generally. In giving each of the Initial
         Certification and the Final Certification, the Indenture Trustee shall
         be under no duty or obligation (1) to inspect, review or examine any
         such documents, instruments, securities or other papers to determine
         that they or the signatures thereto are genuine, enforceable, or
         appropriate for the represented purpose or that they have actually been
         recorded or that they are other than what they purport to be on their
         face or (2) to determine whether any Mortgage File should include a
         flood insurance policy, any rider, addenda, surety or guaranty
         agreement, power of attorney, buy down agreement, assumption agreement,
         modification agreement, written assurance or substitution agreement.

                  (d) Recordation Report. No later than the fifth Business Day
         of each third month, commencing in September 1998, the Indenture
         Trustee shall deliver to the Servicer a recordation report dated as of
         the first day of such month, identifying those Mortgage Loans for which
         it has not yet received (1) an original recorded Mortgage or a copy
         thereof certified to be true and correct by the public recording office
         in possession of such Mortgage or (2) an original recorded Assignment
         of the Mortgage to the Indenture Trustee and any required intervening
         Assignments or a copy thereof certified to be a true and correct copy
         by the public recording office in possession of such Assignment.

         The Indenture Trustee shall be entitled to receive the Indenture
Trustee Fee on each Payment Date as provided herein. The Indenture Trustee also
shall be entitled, pursuant to the provisions of Section 6.05 of the Servicing
Agreement, to (i) payment of, or reimbursement for, expenses, disbursements and
advances incurred or made by the Indenture Trustee in accordance with any of the
provisions of this Indenture (including but not limited to the reasonable
compensation and the expenses and disbursements of its counsel and of all
persons not regularly in its employ) as provided in the Servicing Agreement, and

         Section 7.01.  Issuer to Furnish Indenture Trustee Names and Addresses

         of similar form and content as of a date not more than 10 days prior to
         the time such list is furnished; provided, however, that so long as the
         Indenture Trustee is the Bond Registrar, no such list shall be required
         to be furnished.

                  (b) In addition to furnishing to the Indenture Trustee the

         Bonds contained in the most recent list, if any, furnished to the

<PAGE>   58

         Holders of Bonds any reports required by TIA Section 313(b)(1). For
         purposes of the information required to be included in any such reports
         pursuant to TIA Sections 313(a)(2), 313(b)(1) (if applicable), or
         313(b)(2), the principal amount of indenture securities outstanding on

                                  ARTICLE VIII

           Accounts, Payments of Interest and Principal, and Releases

         Section 8.01.  Collection of Moneys.

         Except as otherwise expressly provided herein, the Indenture Trustee
may demand payment or delivery of, and shall receive and collect, directly and
without intervention or assistance of any fiscal agent or other intermediary,
all money and other property payable to or receivable by the Indenture Trustee
pursuant to this Indenture. The Indenture Trustee shall hold all such money and
property received by it as part of the Trust Estate and shall apply it as
provided in this Indenture.

         If the Indenture Trustee shall not have received the Remittable Funds
by close of business on any related Deposit Date, the Indenture Trustee shall,
unless the Issuer or the Servicer shall have made provisions satisfactory to the
Indenture Trustee for delivery to the Indenture Trustee of an amount equal to
such Remittable Funds, deliver a notice to the Issuer and the Servicer of their
failure to remit such Remittable Funds and that such failure, if not remedied by
the close of business on the Business Day after the date upon which such notice
is delivered to the Servicer, shall constitute an event of default under the
Servicing Agreement. If the Indenture Trustee shall subsequently receive any
such Remittable Funds by 2:00 p.m. Eastern Time on such Business Day, such event
of default shall not be deemed to have occurred. Notwithstanding any other
provision hereof, the Indenture Trustee shall deliver to the Issuer or the
Servicer, or their respective designee or assignee, any Remittable Funds
received with respect to a Mortgage Loan after the related Deposit Date to the
extent that the Issuer or the Servicer, respectively, previously made payment or
provision for payment with respect to such Remittable Funds in accordance with
this Section 8.01, and any such Remittable Funds shall not be deemed part of the
Trust Estate.

         Except as otherwise expressly provided in this Indenture and the
Servicing Agreement, if, following delivery by the Indenture Trustee of the
notice described above, the Servicer shall fail to remit the Remittable Funds by
2:00 p.m. Eastern Time of the Business Day after which such notice is delivered
to the Servicer, the Indenture Trustee shall deliver a second notice to the
Servicer and the Issuer by 2:00 p.m. Eastern Time on the third Business Day
prior to the related Payment Date indicating that an event of default occurred
and is continuing under the Servicing Agreement. Thereupon, the Indenture
Trustee shall take such actions as are required of the Indenture Trustee under
Article VI of the Servicing Agreement. In addition, if a default occurs in any
other performance required under the Servicing Agreement, the Indenture Trustee
may, and upon the request of the Holders of Bonds representing more than 50% of
the Bond Balance of the Outstanding Bonds shall, take such action as may be
appropriate to enforce such payment or performance including the institution and
prosecution of appropriate 



                                      -52-
<PAGE>   59

Proceedings. Any such action shall be without prejudice to any right to claim a
Default or Event of Default under this Indenture and to proceed thereafter as
provided in Article V.

         Section 8.02.  Bond Account.

                  (a) The Issuer hereby directs the Indenture Trustee to
         establish, at the Corporate Trust Office, one or more accounts that
         shall collectively be the "Bond Account" on or before the Closing Date.
         The Indenture Trustee shall promptly deposit in the Bond Account (i)
         all Remittable Funds received by it from the Servicer pursuant to the
         Servicing Agreement, (ii) any other funds from any deposits to be made
         by the Servicer pursuant to the Servicing Agreement, (iii) any amount
         required to be deposited in the Bond Account pursuant to Section 8.01,
         and (iv) all other amounts received for deposit in the Bond Account,
         including the payment of any Purchase Price received by the Indenture
         Trustee. All amounts that are deposited from time to time in the Bond
         Account are subject to withdrawal by the Indenture Trustee for the
         purposes set forth in subsections (c) and (d) of this Section 8.02. All
         funds withdrawn from the Bond Account pursuant to subsection (c) of
         this Section 8.02 for the purpose of making payments to the Holders of
         Bonds shall be applied in accordance with Section 2.14, Section 2.15,
         Section 2.16 and Section 3.03.

                  (b) So long as no Default or Event of Default shall have
         occurred and be continuing, amounts held in the Bond Account shall be
         invested in Permitted Investments, which Permitted Investments shall
         mature no later than the Business Day preceding the immediately
         following Payment Date or, if such Permitted Investments are an
         obligation of the Indenture Trustee or are money market funds for which
         the Indenture Trustee or any affiliate is the manager or the advisor,
         such Permitted Investments shall mature no later than the following
         Payment Date.

                  All income or other gains, if any, from investment of moneys
         deposited in the Bond Account shall be for the benefit of the Indenture
         Trustee and on each Payment Date, any such amounts may be released from
         the Bond Account and paid to the Indenture Trustee as part of its
         compensation for acting as Indenture Trustee. Any loss resulting from
         such investment of moneys deposited in the Bond Account shall be
         reimbursed immediately as incurred to the Bond Account by the Indenture
         Trustee. Subject to Section 6.01 and the preceding sentence, the
         Indenture Trustee shall not in any way be held liable by reason of any
         insufficiency in the Bond Account.

                  (c) On each Payment Date, the Indenture Trustee shall withdraw
         amounts on deposit in the Bond Account and pay on a pari passu basis
         the Indenture Trustee Fee, and, provided notice is given to the
         Indenture Trustee no later than the 4th Business Day prior to the
         Payment Date, amounts required to pay the Servicer any unpaid Monthly
         Servicing Fees then due and to reimburse the Servicer for Monthly
         Advances and Servicing Advances previously made by, and not previously
         reimbursed to or retained by, the Servicer, which are so reimbursable
         to the Servicer pursuant to the Servicing Agreement (as reported in
         writing by the Servicer to the Indenture Trustee). After payment of
         such amounts, unless the Bonds have been declared due and payable
         pursuant to Section 5.02 and moneys collected by the Indenture Trustee
         are being applied in accordance with Section 5.07, Available Funds on
         deposit in the Bond Account on any Payment Date or Redemption Date
         shall be withdrawn from the Bond Account, in the amounts required, for
         application on such Payment Date as follows:

                  (i)   first, to the Bondholders, the Interest Remittance
         Amount applied to Bond Interest for such Payment Date as specified in
         Section 2.14;

                  (ii)  second, to the Bondholders, the Principal Payment Amount

                  (d) On or after each Payment Date, so long as the Indenture
         Trustee shall have prepared a Payment Date Statement in respect of such
         Payment Date and (1) shall have made, or, in accordance with Section
         3.03, set aside from amounts in the Bond Account an amount sufficient
         to make, the payments required to be made as set forth in Section
         8.02(c) as indicated in such Payment Date Statement, and (2) shall have
         set aside any amounts that have been deposited in the Bond Account
         prior to such time that represent amounts that are to be used to make
         payments on the Bonds on the next succeeding Payment Date, the cash
         balance, if any, then remaining in the Bond Account shall be withdrawn
         from the Bond Account by the Indenture Trustee and, so long as no
         Default or Event of Default shall have occurred and be continuing,
         shall be released from the lien of this Indenture and paid by the
         Indenture Trustee to the Certificateholders.

                  (e) Any payments made by the Indenture Trustee to the
         Certificateholders pursuant to this Section 8.02 shall be remitted to
         the Certificate Distribution Account established and maintained
         pursuant to the Trust Agreement.

                  (f) In the event the Indenture Trustee is required to
         establish a Collection Account pursuant to the Servicing Agreement, the
         Indenture Trustee shall establish and maintain such account in the
         manner required under the Servicing Agreement. The Indenture Trustee
         shall reinvest amounts in the Collection Account at the direction of
         the Servicer in Permitted Investments. All income or other gains, if
         any, from investment of moneys deposited in the Collection Account
         shall be for the benefit of the Servicer and the Indenture Trustees
         shall release any such amounts from the Collection Account to the
         Servicer on each Deposit Date.

         Section 8.03. [Intentionally Omitted.]

         Section 8.04. General Provisions Regarding the Bond Account and 
Mortgage Loans.

                  (a) The Bond Account shall relate solely to the Bonds and to
         the Mortgage Loans, Permitted Investments and other property securing
         the Bonds. Funds and other property in the Bond Account shall not be
         commingled with any other moneys or property of the Issuer or any
         Affiliate thereof. Notwithstanding the foregoing, the Indenture Trustee
         may hold any funds or other property received or held by it as part of
         the Bond Account in collective accounts maintained by it in the normal
         course of its business and containing funds or property held by it for
         other Persons (which may include the Issuer or an Affiliate), provided
         that such accounts are under the sole control of the Indenture Trustee
         and the Indenture Trustee maintains adequate records indicating the
         ownership of all such funds or property and the portions thereof held
         for credit to the Bond Account.

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

                  (c) The Indenture Trustee shall, at all times while any Bonds
         are Outstanding, maintain in its possession, or in the possession of an
         agent whose actions with respect to such items are under the sole
         control of the Indenture Trustee, all certificates or other
         instruments, if any, evidencing any investment of funds in the Bond
         Account. The Indenture Trustee shall relinquish possession of such
         items, or direct its agent to do so, only for purposes of collecting
         the final payment receivable on such investment or certificate or, in
         connection with the sale of any investment held in the Bond Account,
         against delivery of the amount receivable in connection with any sale.

                  (d) The Indenture Trustee shall not invest any part of the
         Trust Estate in Permitted Investments that constitute uncertificated
         securities (as defined in Section 8-102 of the Uniform Commercial Code,
         as enacted in the relevant jurisdiction) or in any other book-entry
         securities unless it has received an Opinion of Counsel reasonably
         satisfactory in form and substance to the Indenture Trustee setting
         forth, with respect to each type of security for which authority to
         invest is being sought, the 



                                      -54-

         procedures that must be followed to maintain the lien and security
         interest created by this Indenture with respect to the Trust Estate.

         Section 8.05.  Releases of Defective Mortgage Loans.

         Upon notice or discovery that any of the representations or warranties
of the Mortgage Loan Seller set forth in Section 4(b) and Exhibit B of the
Mortgage Loan Sale Agreement was materially incorrect or otherwise misleading
with respect to any Mortgage Loan as of the time made, the Indenture Trustee
shall direct the Mortgage Loan Seller to either (i) within 60 days after the
Mortgage Loan Seller receives actual knowledge of such incorrectness, eliminate
or otherwise cure the circumstance or condition in respect of which such
representation or warranty was incorrect as of the time made, (ii) withdraw such
Defective Mortgage Loan from the lien of this Indenture following the expiration
of such 60-day period by depositing to the Bond Account an amount equal to the
Purchase Price for such Mortgage Loan or (iii) substitute a Qualified
Replacement Mortgage Loan for such Defective Mortgage Loan and deposit any
Purchase Price required to be paid in connection with such substitution pursuant
to Section 7 of the Mortgage Loan Sale Agreement, all as provided in Section 7
of the Mortgage Loan Sale Agreement. Upon any purchase of or substitution for a
Defective Mortgage Loan by the Mortgage Loan Seller in accordance with Section 7
of the Mortgage Sale Agreement, the Indenture Trustee shall deliver the Mortgage
File relating to such Defective Mortgage Loan to the Mortgage Loan Seller, and
the Issuer and the Indenture Trustee shall execute such instruments of transfer
as are necessary to convey title to such Defective Mortgage Loan to the Mortgage
Loan Seller from the lien of this Indenture.

         Section 8.06.  Reports by Indenture Trustee to Bondholders; Access to
Certain Information.

         On each Payment Date, the Indenture Trustee shall deliver the written
report required by Section 2.08(d) to Bondholders of record as of the related
Record Date (including the Clearing Agency, if any).

         The Indenture Trustee shall make available at its Corporate Trust
Office, during normal business hours, for review by any Bondholder or any Person
identified to the Indenture Trustee as a prospective Bondholder, originals or
copies of the following items: (a) the Indenture and any amendments thereto, (b)
all Payment Date Statements delivered to the Issuer since the Closing Date, (c)
any Officers' Certificates delivered to the Indenture Trustee since the Closing
Date as described in the Indenture and (d) any Accountants' reports delivered to
the Indenture Trustee since the Closing Date as required under the Servicing
Agreement. Copies of any and all of the foregoing items will be available from
the Indenture Trustee upon request; however, the Indenture Trustee will be
permitted to require payment of a sum sufficient to cover the reasonable costs
and expenses of providing such copies and shall not be required to provide such
copies without reasonable assurances that such sum will be paid.

         Section 8.07.  Trust Estate Mortgage Files.

                  (a) The Indenture Trustee shall release Mortgage Files or
         portions thereof to the Servicer on the terms specified in the
         Servicing Agreement.

                  (b) The Indenture Trustee shall, at such time as there are no
         Bonds outstanding, release all of the Trust Estate to the Issuer (other
         than any cash held for the payment of the Bonds pursuant to Section
         3.03 or 4.02).

         Section 8.08.  Amendment to Servicing Agreement.

         The Indenture Trustee may, without the consent of any Holder, enter
into or consent to any amendment or supplement to the Servicing Agreement for
the purpose of increasing the obligations or duties of any party other than the
Indenture Trustee or the Holders of the Bonds. The Indenture Trustee may, in its
discretion, decline to enter into or consent to any such supplement or
amendment: (i) unless the Indenture Trustee receives an Opinion of Counsel that
the position of the Holders would not be materially adversely affected or
written confirmation from the Rating Agencies that the then-current ratings on
the Bonds would not be adversely affected by such supplement or amendment or
(ii) if its own rights, duties or immunities would be adversely affected.



                                      -55-

         Section 8.09.  Delivery of the Mortgage Files Pursuant to Servicing
Agreement.

         As is appropriate for the servicing or foreclosure of any Mortgage
Loan, the Indenture Trustee shall deliver to the Servicer of such Mortgage the
Mortgage Files for such Mortgage Loan upon receipt by the Indenture Trustee on
or prior to the date such release is to be made of:

                  (a) such Officers' Certificates, if any, as are required by
         the Servicing Agreement; and

                  (b) a "Request for Release" in the form prescribed by the
         Servicing Agreement, executed by the Servicer, providing that the
         Servicer will hold or retain the Mortgage Files in trust for the
         benefit of the Indenture Trustee and the Holders of Bonds.

         Section 8.10.  Servicer as Agent.

         In order to facilitate the servicing of the Mortgage Loans by the
Servicer of such Mortgage Loans, the Servicer of the Mortgage Loans has been
appointed by the Issuer to retain, in accordance with the provisions of the
Servicing Agreement and this Indenture, all Remittable Funds on such Mortgage
Loans prior to their deposit into the Bond Account on or prior to the related
Deposit Date.

         Section 8.11.  Termination of Servicer.

         In the event of an event of default specified in Section 6.01 of the
Servicing Agreement, the Indenture Trustee may (or as otherwise provided in the
Servicing Agreement shall) terminate the Servicer as provided in Section 6.01
and Section 6.02 of the Servicing Agreement. If the Indenture Trustee terminates
the Servicer, the Indenture Trustee shall pursuant to Section 6.02 of the
Servicing Agreement assume the duties of the Servicer or appoint a successor
servicer acceptable to the Issuer and the Rating Agencies and meeting the
requirements set forth in the Servicing Agreement.

         Section 8.12.  Opinion of Counsel.

         The Indenture Trustee shall be entitled to receive at least five
Business Days' notice of any action to be taken pursuant to Section 8.07(a)
(other than in connection with releases of Mortgage Loans that were the subject
of a Full Prepayment of the type described in clause (i) of the definition of
the term "Full Prepayment") and 8.08, accompanied by copies of any instruments
involved, and the Indenture Trustee shall be entitled to receive an Opinion of
Counsel, in form and substance reasonably satisfactory to the Indenture Trustee,
stating the legal effect of any such action, outlining the steps required to
complete the same, and concluding that all conditions precedent to the taking of
such action have been complied with. Counsel rendering any such opinion may
rely, without independent investigation, on the accuracy and validity of any
certificate or other instrument delivered to the Indenture Trustee in connection
with any such action.

         Section 8.13.  Appointment of Custodians.

         The Indenture Trustee may, at no additional cost to the Issuer, with
the consent of the Issuer, appoint one or more Custodians to hold all or a
portion of the Mortgage Files as agent for the Indenture Trustee. Each Custodian
shall (i) be a financial institution supervised and regulated by the Comptroller
of the Currency, the Board of Governors of the Federal Reserve System, the
Office of Thrift Supervision, or the Federal Deposit Insurance Corporation; (ii)
have combined capital and surplus of at least $10,000,000; (iii) be equipped
with secure, fireproof storage facilities, and have adequate controls on access
to assure the safety and security of the Mortgage Files; (iv) utilize in its
custodial function employees who are knowledgeable in the handling of mortgage
documents and of the functions of a mortgage document custodian; and (v) satisfy
any other reasonable requirements that the Issuer may from time to time deem
necessary to protect the interests of Bondholders in the Mortgage Files. Each
Custodian shall be subject to the same obligations and standard of care as would
be imposed on the Indenture Trustee hereunder assuming the Indenture Trustee
retained the Mortgage Files directly. The appointment of one or more Custodians
shall not relieve the Indenture Trustee from any of its obligations hereunder,
and the Indenture Trustee 



                                      -56-
<PAGE>   63

shall remain responsible for all acts and omissions of any Custodian. If the
Servicer is appointed as a Custodian in accordance with this Section 8.13, it
shall fulfill its servicing and custodial duties and obligations through
separate departments and, if it maintains a trust department, shall fulfill its
custodial duties and obligations through such trust department.

                             SUPPLEMENTAL INDENTURES

         Section 9.01.  Supplemental Indentures Without Consent of Bondholders.

         Without the consent of the Holders of any Bonds, the Issuer and the
Indenture Trustee, at any time and from time to time, may enter into one or more
indentures supplemental hereto, in form satisfactory to the Indenture Trustee,
for any of the following purposes:

                  (1) to correct or amplify the description of any property at
         any time subject to the lien of this Indenture, or better to assure,
         convey and confirm unto the Indenture Trustee any property subject or
         required to be subjected to the lien of this Indenture, or to subject
         to the lien of this Indenture additional property;

                  (2) to add to the conditions, limitations and restrictions on
         the authorized amount, terms and purposes of the issuance,
         authentication and delivery of any Bonds, as herein set forth,
         additional conditions, limitations and restrictions thereafter to be
         observed;

                  (3) to evidence the succession of another Person to the Issuer
         to the extent permitted herein, and the assumption by any such
         successor of the covenants of the Issuer herein and in the Bonds
         contained;

                  (4) to add to the covenants of the Issuer, for the benefit of
         the Holders of all Bonds or to surrender any right or power herein
         conferred upon the Issuer;

                  (5) to cure any ambiguity, to correct or supplement any
         provision herein that may be defective or inconsistent with any other
         provision herein, or to amend any other provisions with respect to
         matters or questions arising under this Indenture, which shall not be
         inconsistent with the provisions of this Indenture, provided that such
         action shall not adversely affect in any material respect the interests
         of the Holders of the Bonds; and provided, further, that the amendment
         shall not be deemed to adversely affect in any material respect the
         interests of the Holders of the Bonds if the Person requesting the
         amendment obtains letters from the Rating Agencies that the amendment
         would not result in the downgrading or withdrawal of the then current
         ratings then assigned to the Bonds; or

                  (6) to modify, eliminate or add to the provisions of this
         Indenture to such extent as shall be necessary to effect the
         qualification of this Indenture under the TIA or under any similar
         federal statute hereafter enacted, and to add to this Indenture such
         other provisions as may be expressly required by the TIA.

         Section 9.02.  Supplemental Indentures with Consent of Bondholders.

         With the consent of Holders of Bonds representing not less than a
majority of the Bond Balance of all Outstanding Bonds, or if fewer than all
Classes would be affected, each Class to be affected, by Act of said Holders
delivered to the Issuer and the Indenture Trustee, the Issuer and the Indenture
Trustee may enter into an indenture or indentures supplemental hereto for the
purpose of adding any provisions to, or changing in any manner or eliminating
any of the provisions of, this Indenture, relating to such Class or Classes, or
of modifying in any manner the rights of the Holders of the Bonds, or of such
Class or Classes, under this Indenture; provided, however, that no such
supplemental indenture shall, without the consent of the Holder of each
Outstanding Bond affected thereby:



                                      -57-
<PAGE>   64

                  (1) change the any Payment Date or the Final Maturity Date of
         the Bonds or reduce the principal amount thereof, the Bond Interest
         Rate thereon or the Redemption Price with respect thereto, change the
         earliest date on which any Bond may be redeemed at the option of the
         Issuer, change any place of payment where, or the coin or currency in
         which, any Bond or any interest thereon is payable, or impair the right
         to institute suit for the enforcement of the payment of any installment
         of interest due on any Bond on or after the Final Maturity Date thereof
         or for the enforcement of the payment of the entire remaining unpaid
         principal amount of any Bond on or after the Final Maturity Date (or,
         in the case of redemption, on or after the applicable Redemption Date);

                  (2) reduce the percentage of the Bond Balance of the
         Outstanding Bonds, the consent of the Holders of which is required for
         any such supplemental indenture, or the consent of the Holders of which
         is required for any waiver of compliance with provisions of this
         Indenture or Defaults hereunder and their consequences provided for in
         this Indenture;

                  (3) modify any of the provisions of this Section, Section 5.13
         or Section 5.17(b), except to increase any percentage specified therein
         or to provide that certain other provisions of this Indenture cannot be
         modified or waived without the consent of the Holder of each
         Outstanding Bond affected thereby;

                  (4) modify or alter the provisions of the proviso to the
         definition of the term "Outstanding";

                  (5) permit the creation of any lien other than the lien of
         this Indenture with respect to any part of the Trust Estate (except for
         Permitted Encumbrances) or terminate the lien of this Indenture on any
         property at any time subject hereto or deprive the Holder of any Bond
         of the security afforded by the lien of this Indenture;

                  (6) modify any of the provisions of this Indenture in such
         manner as to affect the calculation of the Required Payment Amount for
         any Payment Date (including the calculation of any of the individual
         components of such Required Payment Amount) or to affect rights of the
         Holders of the Bonds to the benefits of any provisions for the
         mandatory redemption of Bonds contained herein; or

                  (7) incur any indebtedness, other than the Bonds, that would
         cause the Issuer or the Trust Estate to be treated as a "taxable
         mortgage pool" within the meaning of Code Section 7701(i).

         The Indenture Trustee may in its discretion determine whether or not
any Bonds of a particular Class would be affected by any supplemental indenture
and any such determination shall be conclusive upon the Holders of such Class of
Bonds, whether theretofore or thereafter authenticated and delivered hereunder.
The Indenture Trustee shall not be liable for any such determination made in
good faith.

         It shall not be necessary for any Act of Bondholders under this Section
to approve the particular form of any proposed supplemental indenture, but it
shall be sufficient if such Act shall approve the substance thereof.

         Promptly after the execution by the Issuer and the Indenture Trustee of
any supplemental indenture pursuant to this Section, the Indenture Trustee shall
mail to the Holders of the Bonds to which such supplemental indenture relates a
notice setting forth in general terms the substance of such supplemental
indenture. Any failure of the Indenture Trustee to mail such notice, or any
defect therein, shall not, however, in any way impair or affect the validity of
any such supplemental indenture.

         Section 9.03.  Execution of Supplemental Indentures.

         In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modifications thereby of
the trusts created by this Indenture, the Indenture Trustee shall be entitled to
receive, and (subject to Section 6.01) shall be fully protected in relying upon,
an Opinion of Counsel stating that the execution of such supplemental indenture
is authorized or permitted by this Indenture. The Indenture Trustee may, 



                                      -58-
<PAGE>   65

but shall not be obligated to, enter into any such supplemental indenture that
affects the Indenture Trustee's own rights, duties or immunities under this
Indenture or otherwise. The Issuer shall cause executed copies of any
supplemental indentures to be delivered to the Rating Agencies.

         Section 9.04.  Effect of Supplemental Indentures.

         Upon the execution of any supplemental indenture under this Article,
this Indenture shall be modified in accordance therewith, and such supplemental
indenture shall form a part of this Indenture for all purposes; and every Holder
of Bonds to which such supplemental indenture relates that have theretofore been
or thereafter are authenticated and delivered hereunder shall be bound thereby.

         Section 9.05.  Conformity with Trust Indenture Act.

         Every supplemental indenture executed pursuant to this Article shall
conform to the requirements of the TIA as then in effect so long as this
Indenture shall then be qualified under the TIA.

         Section 9.06.  Reference in Bonds to Supplemental Indentures.

         Bonds authenticated and delivered after the execution of any
supplemental indenture pursuant to this Article may, and if required by the
Indenture Trustee shall, bear a notation in form approved by the Indenture
Trustee as to any matter provided for in such supplemental indenture. If the
Issuer shall so determine, new Bonds so modified as to conform, in the opinion
of Indenture Trustee and the Issuer, to any such supplemental indenture may be
prepared and executed by the Issuer and authenticated and delivered by the
Indenture Trustee in exchange for Outstanding Bonds.

         Section 9.07.  Amendments to Governing Documents.

         The Indenture Trustee shall, upon Issuer Request, consent to any
proposed amendment to the Issuer's governing documents, or an amendment to or
waiver of any provision of any other document relating to the Issuer's governing
documents, such consent to be given without the necessity of obtaining the
consent of the Holders of any Bonds upon receipt by the Indenture Trustee of:

                  (i)  an Officers' Certificate, to which such proposed 
         amendment or waiver shall be attached, stating that such attached copy
         is a true copy of the proposed amendment or waiver and that all
         conditions precedent to such consent specified in this Section 9.07
         have been satisfied; and

                  (ii) written confirmation from the Rating Agencies that the
         implementation of the proposed amendment or waiver will not adversely
         affect the then current ratings of the Bonds.

         Notwithstanding the foregoing, the Indenture Trustee may decline to
consent to a proposed waiver or amendment that adversely affects its own rights,
duties or immunities under this Indenture or otherwise.

         Nothing in this Section 9.07 shall be construed to require that any
Person obtain the consent of the Indenture Trustee to any amendment or waiver or
any provision of any document where the making of such amendment or the giving
of such waiver without obtaining the consent of the Indenture Trustee is not
prohibited by this Indenture or by the terms of the document that is the subject
of the proposed amendment or waiver.

                               REDEMPTION OF BONDS

         Section 10.01.  Redemption.

                  (a) The Bonds may be redeemed in whole, but not in part, on a
         Payment Date that occurs on or after the Clean-Up Call Date at the
         aggregate Redemption Price of all the Bonds at the option of the
         holder(s) of a majority of the ownership interest in the Certificate
         (the "Residual Majority"), or at the option of the Servicer if the
         Residual Majority shall not have exercised its option to redeem the
         Bonds on such date, provided, however, that funds in an amount equal to
         the Redemption Price, plus any unreimbursed Nonrecoverable Advances and
         any unreimbursed amounts due and owing to the Indenture Trustee
         hereunder, must have been deposited with the Indenture Trustee prior to
         the Indenture Trustee's giving notice of such redemption pursuant to
         Section 10.02 or, the Issuer shall have complied with the requirements
         for satisfaction and discharge of the Bonds specified in Section 4.01.
         Notice of the election to redeem the Bonds shall be furnished to the
         Indenture Trustee not later than thirty (30) days prior to the Payment
         Date selected for such redemption, whereupon all such Bonds shall be
         due and payable on such Payment Date upon the furnishing of a notice
         pursuant to Section 10.02 to each Holder of such Bonds. Any expenses
         associated with the compliance of the provisions hereof in connection
         with a redemption of the Bonds shall be paid by the Residual Majority
         or the Servicer, depending upon which party is electing to redeem the
         Bonds.

                  (b) Upon receipt of the notice from the Residual Majority or
         the Servicer of its election to redeem the Bonds pursuant to Section
         10.01(a), the Indenture Trustee shall prepare and deliver to the
         Issuer, no later than the proposed Redemption Date, a Payment Date
         Statement stating therein that it has determined that the conditions to
         redemption at the option of the Issuer have been satisfied and setting
         forth the amount, if any, to be withdrawn from the Bond Account and
         paid to the Servicer as reimbursement for Nonrecoverable Advances and
         such other information as may be required to accomplish such
         redemption.

                  (c) Subject to Section 10.04, upon surrender of, and payment
         for, the Bonds subject to redemption, such Bonds shall be retired and
         cancelled by the Issuer.

                  (d) Upon redemption and retirement of all the Bonds, the
         remaining Mortgage Loans securing the Bonds will be released from the
         lien of this Indenture.

                  (e) There will be no prepayment premium in connection with any
         redemption of a Class or Classes of the Bonds under this Article X.

         SECTION 10.02.  FORM OF REDEMPTION NOTICE.

         Notice of redemption shall be given by the Indenture Trustee in the
name of and at the expense of the Issuer by first class mail, postage prepaid,
mailed not less than ten days prior to the proposed Redemption Date to each
Holder of Bonds to be redeemed, such Holders being determined as of the Record
Date for such Payment Date.

         All notices of redemption shall state:

                  (1) the proposed Redemption Date;

                  (2) the Redemption Price at which the Bonds will be redeemed;

                  (3) the fact of payment in full on such Bonds, the place where
         such Bonds are to be surrendered for payment of the Redemption Price
         (which shall be the office or agency of the Issuer to be 



                                      -60-

         maintained as provided in Section 3.02), and that no interest shall
         accrue on such Bond for any period after the date fixed for redemption.

         Failure to give notice of redemption, or any defect therein, to any
Holder of any Bond selected for redemption shall not impair or affect the
validity of the redemption of any other Bond.

         Section 10.03.  Bonds Payable on Optional Redemption.

         Notice of redemption having been given as provided in Section 10.02,
each Bond to be redeemed shall, on the proposed Redemption Date, become due and
payable at the applicable Redemption Price and (unless the Issuer shall default
in the payment of the Redemption Price) no interest shall accrue on such
Redemption Price for any period after such Redemption Date; provided, however,
that if such Redemption Price is not paid on the proposed Redemption Date, the
Bond Balance shall, until paid, bear interest from the Redemption Date at the
Bond Interest Rate. The payment on the applicable Payment Date of the Redemption
Price shall be in lieu of the payment otherwise required to be made on such
Payment Date in respect of the Bonds.

         Section 10.04.  Resale of Redeemed Bonds.

         At the option of the Residual Majority (or if not exercised, the
Servicer), an optional redemption of the Bonds under this Article X may be
effected without retiring and canceling the Bonds so that the redeeming party or
a designee has the ability to own or resell such Class or Classes of the Bonds.

                                   ARTICLE XI

                                  MISCELLANEOUS

         Section 11.01.  Compliance Certificates and Opinions.

                  (a) Upon any application or request by the Issuer to the
         Indenture Trustee to take any action under any provision of this
         Indenture, the Issuer shall furnish to the Indenture Trustee an
         Officers' Certificate stating that all conditions precedent, if any,
         provided for in this Indenture relating to the proposed action have
         been complied with and an Opinion of Counsel, if requested by the
         Indenture Trustee, stating that in the opinion of such counsel all such
         conditions precedent, if any, have been complied with, except that in
         the case of any such application or request as to which the furnishing
         of such documents is specifically required by any provision of this
         Indenture relating to such particular application or request, no
         additional certificate or opinion need be furnished.

                  (b) Every certificate, opinion or letter with respect to
         compliance with a condition or covenant provided for in this Indenture,
         including one furnished pursuant to specific requirements of this
         Indenture relating to a particular application or request (other than
         certificates provided pursuant to TIA Section 314(a)(4)) shall include
         and shall be deemed to include (regardless of whether specifically
         stated therein) the following:

                           (1) a statement that each individual signing such
                  certificate, opinion or letter has read such covenant or
                  condition and the definitions herein relating thereto;

                           (2) a brief statement as to the nature and scope of
                  the examination or investigation upon which the statements or
                  opinions contained in such certificate, opinion or letter are
                  based;

                           (3) a statement that, in the opinion of each such
                  individual, he has made such examination or investigation as
                  is necessary to enable him to express an informed opinion as
                  to whether or not such covenant or condition has been complied
                  with; and



                                      -61-
<PAGE>   68

                           (4) a statement as to whether, in the opinion of each
                  such individual, such condition or covenant has been complied
                  with.

         Section 11.02.  Form of Documents Delivered to Indenture Trustee.

         In any case where several matters are required to be certified by, or
covered by an opinion of, any specified Person, it is not necessary that all
such matters be certified by, or covered by the opinion of, only one such
Person, or that they be so certified or covered by only one document, but one
such Person may certify or give an opinion with respect to some matters and one
or more other such Persons as to other matters, and any such Person may certify
or give an opinion as to such matters in one or several documents.

         Any certificate or opinion of the Issuer may be based, insofar as it
relates to legal matters, upon a certificate or opinion of, or representations
by, counsel, unless such officer knows, or in the exercise of reasonable care
should know, that the certificate or opinion or representations with respect to
the matters upon which his certificate or opinion is based are erroneous. Any
Opinion of Counsel may be based on the written opinion of other counsel, in
which event such Opinion of Counsel shall be accompanied by a copy of such other
counsel's opinion and shall include a statement to the effect that such counsel
believes that such counsel and the Indenture Trustee may reasonably rely upon
the opinion of such other counsel.

         Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.

         Wherever in this Indenture, in connection with any application or
certificate or report to the Indenture Trustee, it is provided that the Issuer
shall deliver any document as a condition of the granting of such application,
or as evidence of the Issuer's compliance with any term hereof, it is intended
that the truth and accuracy, at the time of the granting of such application or
at the effective date of such certificate or report (as the case may be), of the
facts and opinions stated in such document shall in such case be conditions
precedent to the right of the Issuer to have such application granted or to the
sufficiency of such certificate or report. The foregoing shall not, however, be
construed to affect the Indenture Trustee's right to rely upon the truth and
accuracy of any statement or opinion contained in any such document as provided
in Section 6.01(b)(2).

         Whenever in this Indenture it is provided that the absence of the
occurrence and continuation of a Default or Event of Default is a condition
precedent to the taking of any action by the Indenture Trustee at the request or
direction of the Issuer, then, notwithstanding that the satisfaction of such
condition is a condition precedent to the Issuer's right to make such request or
direction, the Indenture Trustee shall be protected in acting in accordance with
such request or direction if it does not have knowledge of the occurrence and
continuation of such Default or Event of Default as provided in Section 6.01(d).

         Section 11.03.  Acts of Bondholders.

                  (a) Any request, demand, authorization, direction, notice,
         consent, waiver or other action provided by this Indenture to be given
         or taken by Bondholders may be embodied in and evidenced by one or more
         instruments of substantially similar tenor signed by such Bondholders
         in person or by an agent duly appointed in writing; and, except as
         herein otherwise expressly provided, such action shall become effective
         when such instrument or instruments are delivered to the Indenture
         Trustee, and, where it is hereby expressly required, to the Issuer.
         Such instrument or instruments (and the action embodied therein and
         evidenced thereby) are herein sometimes referred to as the "Act" of the
         Bondholders signing such instrument or instruments. Proof of execution
         of any such instrument or of a writing appointing any such agent shall
         be sufficient for any purpose of this Indenture and (subject to Section
         6.01) conclusive in favor of the Indenture Trustee and the Issuer, if
         made in the manner provided in this Section.

                  (b) The fact and date of the execution by any Person of any
         such instrument or writing may be proved by the affidavit of a witness
         of such execution or by the certificate of any notary public or other


                                      -62-
<PAGE>   69

         officer authorized by law to take acknowledgments of deeds, certifying
         that the individual signing such instrument or writing acknowledged to
         him the execution thereof. Whenever such execution is by an officer of
         a corporation or a member of a partnership on behalf of such
         corporation or partnership, such certificate or affidavit shall also
         constitute sufficient proof of his authority.

                  (c) The ownership of Bonds shall be proved by the Bond
         Register.

                  (d) Any request, demand, authorization, direction, notice,
         consent, waiver or other action by the Holder of any Bonds shall bind
         the Holder of every Bond issued upon the registration of transfer
         thereof or in exchange therefor or in lieu thereof, in respect of
         anything done, omitted or suffered to be done by the Indenture Trustee
         or the Issuer in reliance thereon, whether or not notation of such
         action is made upon such Bonds.

         Section 11.04.  Notices, Etc. to Indenture Trustee and Issuer.

         Any request, demand, authorization, direction, notice, consent, waiver
or Act of Bondholders or other documents provided or permitted by this Indenture

                  (4) the Mortgage Loan Seller or the Servicer by the Indenture
         Trustee or by any Bondholder shall be sufficient for every purpose
         hereunder if in writing and mailed, first-class, postage paid, to
         National Mortgage Corporation, 7600 East Orchard Road, Suite 330S,

                  (5) the Underwriter by any party or by any Bondholder shall be

         Section 11.05.  Notices and Reports to Bondholders; Waiver of Notices.

         Where this Indenture provides for notice to Bondholders of any event or
the mailing of any report to Bondholders, such notice or report shall be
sufficiently given (unless otherwise herein expressly provided) if mailed,
first-class postage prepaid, to each Bondholder affected by such event or to
whom such report is required to be mailed, at the address of such Bondholder as
it appears on the Bond Register, not later than the latest date, and not earlier
than the earliest date, prescribed for the giving of such notice or the mailing
of such report. In any case where a notice or report to Bondholders is mailed in
the manner provided above, neither the failure to mail such notice or report,
nor any defect in any notice or report so mailed, to any particular Bondholder
shall affect the sufficiency of such notice or report with respect to other
Bondholders, and any notice or report that is mailed in the manner herein
provided shall be conclusively presumed to have been duly given or provided.

         Where this Indenture provides for notice in any manner, such notice may
be waived in writing by any Person entitled to receive such notice, either
before or after the event, and such waiver shall be the equivalent of such
notice. Waivers of notice by Bondholders shall be filed with the Indenture
Trustee, but such filing shall not be a condition precedent to the validity of
any action taken in reliance upon such waiver.

         In case, by reason of the suspension of regular mail service as a
result of a strike, work stoppage or similar activity, it shall be impractical
to mail notice of any event to Bondholders when such notice is required to be
given pursuant to any provision of this Indenture, then any manner of giving
such notice as shall be satisfactory to the Indenture Trustee shall be deemed to
be a sufficient giving of such notice.

         Section 11.06.  Rules by Indenture Trustee.

         The Indenture Trustee may make reasonable rules for any meeting of
Bondholders.

         Section 11.07.  Conflict with Trust Indenture Act.

         If any provision hereof limits, qualifies or conflicts with another
provision hereof that is required to be included in this Indenture by any of the
provisions of the TIA, such required provision shall control.

         Section 11.08.  Effect of Headings and Table of Contents.

         The Article and Section headings herein and the Table of Contents are
for convenience only and shall not affect the construction hereof.

         Section 11.09.  Successors and Assigns.

         All covenants and agreements in this Indenture by the Issuer shall bind
its successors and assigns, whether so expressed or not.

         Section 11.10.  Separability.

         In case any provision in this Indenture or in the Bonds shall be
invalid, illegal or unenforceable, the validity, legality and enforceability of
the remaining provisions shall not in any way be affected or impaired thereby.

         Section 11.11.  Benefits of Indenture.

         Nothing in this Indenture or in the Bonds, expressed or implied, shall
give to any Person, other than the parties hereto and their successors
hereunder, any separate trustee or Co-trustee appointed under Section 6.14 or
Section 5.21, and the Bondholders, any benefit or any legal or equitable right,
remedy or claim under this Indenture.

         Section 11.12.  Legal Holidays.

         In any case where the date of any Payment Date, Redemption Date or any
other date on which principal of or interest on any Bond is proposed to be paid
shall not be a Business Day, then (notwithstanding any other provision of the
Bonds or this Indenture) payment need not be made on such date, but may be made
on the next succeeding Business Day with the same force and effect as if made on
the nominal date of any such Payment Date, Redemption Date or other date for the
payment of principal of or interest on any Bond and no interest shall accrue for
the period from and after any such nominal date, provided such payment is made
in full on such next succeeding Business Day.

         Section 11.13.  Governing Law.

         IN VIEW OF THE FACT THAT BONDHOLDERS ARE EXPECTED TO RESIDE IN MANY
STATES AND OUTSIDE THE UNITED STATES AND THE DESIRE TO ESTABLISH WITH CERTAINTY
THAT THIS INDENTURE WILL BE GOVERNED BY AND CONSTRUED AND INTERPRETED IN
ACCORDANCE WITH THE LAW OF A STATE HAVING A WELL-DEVELOPED BODY OF COMMERCIAL
AND FINANCIAL LAW RELEVANT TO TRANSACTIONS OF THE TYPE CONTEMPLATED HEREIN, THIS
INDENTURE AND EACH BOND SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY
THE LAWS OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE
PERFORMED THEREIN.

         Section 11.14.  Counterparts.

         This instrument may be executed in any number of counterparts, each of
which so executed shall be deemed to be an original, but all such counterparts
shall together constitute but one and the same instrument.

         Section 11.15.  Recording of Indenture.

         This Indenture is subject to recording in any appropriate public
recording offices, such recording to be effected by the Issuer and at its
expense in compliance with any Opinion of Counsel delivered pursuant to Section
2.11(c) or 3.06.

         Section 11.16.  Issuer Obligation.

         No recourse may be taken, directly or indirectly, with respect to the
obligations of the Issuer, the Owner Trustee or the Indenture Trustee on the
Bonds or under this Indenture or any certificate or other writing delivered in
connection herewith or therewith, against (i) the Indenture Trustee or the Owner
Trustee in its individual capacity, (ii) any owner of a beneficial interest in
the Issuer or (iii) any partner, owner, beneficiary, agent, officer, director,
employee or agent of the Indenture Trustee or the Owner Trustee in its
individual capacity, any holder of a beneficial interest in the Issuer, the
Owner Trustee or the Indenture Trustee or of any successor or assign of the
Indenture Trustee or the Owner Trustee in its individual capacity, except as any
such Person may have expressly agreed (it being understood that the Indenture
Trustee and the Owner Trustee have no such obligations in their individual
capacity) and except that any such partner, owner or beneficiary shall be fully
liable, to the extent provided by applicable law, for any unpaid consideration
for stock, unpaid capital contribution or failure to pay any installment or call
owing to such entity. For all purposes of this Indenture, in the performance of
any duties or obligations of the Issuer hereunder, the Owner Trustee shall be
subject to, and entitled to the benefits of, the terms and provisions of the
Trust Agreement.

         Section 11.17.  No Petition.

         The Indenture Trustee, by entering into this Indenture, and each
Bondholder and Beneficial Owner, by accepting a Bond, hereby covenant and agree
that they will not at any time institute against the Transferor or the Issuer,
or join in any institution against the Transferor or the Issuer of, any
bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings,
or other proceedings under any United States federal or state bankruptcy or



                                      -65-
<PAGE>   72

similar law in connection with any obligations relating to the Bonds, this
Indenture or any of the Basic Documents. In addition, the Indenture Trustee will
on behalf of the holders of the Bonds, (a) file a written objection to any
motion or other proceeding seeking the substantive consolidation of the Mortgage
Loan Seller with National Mortgage Finance Corporation, the Transferor or the
Issuer, (b) file an appropriate memorandum of points and authorities or other
brief in support of such objection, or (c) endeavor to establish at the hearing
on such objection that the substantive consolidation of such entity would be
materially prejudicial to the Bondholders.

         This Section 11.17 will survive for one year AND ONE DAY following the
termination of this Indenture.

         Section 11.18.  Inspection.

         The Issuer agrees that, on reasonable prior notice, it will permit any
representative of the Indenture Trustee, during the Issuer's normal business
hours, to examine all of books of account, records, reports and other papers of
the Issuer, to make copies and extracts therefrom, to cause such books to be
audited by Independent Accountants selected by the Indenture Trustee, and to
discuss its affairs, finances and accounts with its officers, employees and
Independent Accountants (and by this provision the Issuer hereby authorizes its
Accountants to discuss with such representatives such affairs, finances and
accounts), all at such reasonable times and as often as may be reasonably
requested. Any expense incident to the exercise by the Indenture Trustee of any
right under this Section 11.18 shall be reimbursed pursuant to Section 6.16.

         Section 11.19.  Usury.

         The amount of interest payable or paid on any Bond under the terms of
this Indenture shall be limited to an amount that shall not exceed the maximum
nonusurious rate of interest allowed by the applicable laws of the United States
or the State of New York (whichever shall permit the higher rate), that could
lawfully be contracted for, charged or received (the "Highest Lawful Rate"). In
the event any payment of interest on any Bond exceeds the Highest Lawful Rate,
the Issuer stipulates that such excess amount will be deemed to have been paid
as a result of an error on the part of both the Indenture Trustee, acting on
behalf of the Holder of such Bond, and the Issuer, and the Holder receiving such
excess payment shall promptly, upon discovery of such error or upon notice
thereof from the Issuer or the Indenture Trustee, refund the amount of such
excess or, at the option of the Indenture Trustee, apply the excess to the
payment of principal of such Bond, if any, remaining unpaid. In addition, all
sums paid or agreed to be paid to the Indenture Trustee for the benefit of
Holders of Bonds for the use, forbearance or detention of money shall, to the

         THIS MORTGAGE LOAN SALE AGREEMENT (this "Agreement"), made as of June
1, 1998, by and between National Mortgage Corporation, a Colorado corporation
("NMC" or the "Seller"), and Fund America Investors Corporation II, a Delaware
corporation ("FAIC II"), recites and provides as follows:

                                    RECITALS

                  1. Schedule I attached hereto (the "Mortgage Loan Schedule")
and made a part hereof lists adjustable-rate mortgage loans secured by first
liens on real properties (the "Mortgage Loans"). The Mortgage Loans are
currently owned by the Seller and the Seller desires to sell such Mortgage Loans
to FAIC II.

                  2. FAIC II desires to purchase the Mortgage Loans and intends
immediately after its purchase to transfer the Mortgage Loans to Fund America
Investors Trust 1998-NMC1 (the "Issuer"), which will be formed pursuant to the
terms of a deposit trust agreement (the "Trust Agreement"), dated as of June 1,
1998, by and between FAIC II, as depositor, and Wilmington Trust Company, as
trustee (the "Owner Trustee").

                  3. The Issuer will in turn pledge the Mortgage Loans to
Norwest Bank Minnesota, National Association, as trustee (the "Indenture
Trustee"), under an indenture to be dated as of June 1, 1998 (the "Indenture"),
by and between the Issuer and the Indenture Trustee, pursuant to which the
Issuer's Collateralized Mortgage Obligations, Series 1998-NMC1, which will
consist of four classes of bonds (collectively, the "Bonds"), designated as the
Class A Bonds, the Class M-1 Bonds, the Class M-2 Bonds, and the Class M-3
Bonds, will be issued.

                  4. The Bonds shall be sold pursuant to an underwriting
agreement dated as of June 24, 1998 (the "Underwriting Agreement"), between
Salomon Brothers Inc ("Salomon" or the "Underwriter") and FAIC II, and will be
offered publicly for sale by the Underwriter pursuant to a prospectus supplement
dated June 24, 1998 (the "Prospectus Supplement"), and the related prospectus,
dated June 24, 1998 (together with the Prospectus Supplement, the "Prospectus").

                  5. The certificates of beneficial ownership of the Issuer (the
"Trust Certificates") will be transferred by FAIC II to National Mortgage
Finance Corporation, a Colorado corporation ("NMFC"), that is a wholly-owned
subsidiary of the Seller, which intends to hold such Trust Certificates.

                  6. Capitalized terms used and not defined herein shall have
the meanings assigned to them in Exhibit C attached hereto or, if not defined
therein, in the Indenture.

                                    AGREEMENT

         NOW THEREFORE, in consideration of the above premises, the mutual
promises herein made and other good and valuable consideration, the receipt and
adequacy of which are hereby acknowledged, the parties hereto agree as follows:

         SECTION 1.  Sale and Purchase.

         (a) Subject to the terms and conditions of this Agreement, the Seller
agrees to sell, and FAIC II agrees to purchase, on the date of the issuance of
the Bonds (the "Closing Date"), which is expected to be on or about June 29,
1998, Mortgage Loans having an aggregate principal balance of $243,841,234 as of
the close of business on June 1, 1998 (the "Cut-off Date").

         (b) The Seller has prepared, or provided information to FAIC II
enabling it to prepare, the schedule attached hereto as Schedule I identifying
all of the Mortgage Loans to be purchased by FAIC II on the Closing Date and
describing such Mortgage Loans. The Seller shall, with FAIC II's consent, amend
or modify, or provide information to FAIC II enabling it to amend or modify,
Schedule I on or prior to the Closing Date if necessary to reflect the inclusion
of additional Mortgage Loans and the withdrawal of certain of the Mortgage Loans
currently listed on the attached Schedule I. Schedule I, as so amended or
modified (the "Mortgage Loan Schedule"), shall conform to the requirements of
FAIC II as set forth in this Agreement and shall be used as the definitive
mortgage loan schedule attached as an exhibit to the Indenture identifying all
of the Mortgage Loans actually transferred by the Seller and accepted by FAIC II
on the Closing Date.

         (c) The sale of the Mortgage Loans shall be effected pursuant to the
Bill of Sale substantially in the form attached hereto as Exhibit A (the "Bill
of Sale").

         SECTION 2.  Pool Purchase Price.

         (a) On the Closing Date, as full consideration for the Seller's sale of
the Mortgage Loans to FAIC II, FAIC II will (1) pay to the Seller cash in
immediately available funds equal to the proceeds of the sale of the Bonds by
the Issuer, net of underwriting discounts and the Issuance Fee described in
Section 10 below, and (2) transfer the Trust Certificates to NMFC, as the
Seller's designee (collectively, the "Pool Purchase Price").

         (b) FAIC II or any assignee or transferee of FAIC II (which will
include the Issuer and the Indenture Trustee) shall be entitled to all Monthly
Payments due after the Cut-off Date and all Principal Prepayments and other
unscheduled collections of principal collected in respect of the Mortgage Loans
on or after the Cut-off Date. All Monthly Payments due on or before the Cut-off
Date and collected on or after the Cut-off Date shall belong to the Seller.

         (c) Pursuant to the Trust Agreement, FAIC II will transfer and assign
all of its right, title and interest in and to the Mortgage Loans to the Issuer,
which will in turn pledge all of its right, title and interest in and to the
Mortgage Loans to the Indenture Trustee pursuant to the Indenture for the
benefit of the holders of the Bonds.

         SECTION 3.  Transfer of the Mortgage Loans.

         (a) Transfer of Ownership. Upon the sale of the Mortgage Loans, the
ownership of each Mortgage Loan and the related Mortgage Loan Documents shall be
vested in FAIC II, and the ownership of all other records and documents with
respect to any Mortgage Loan prepared by or which come into the possession of
the Seller shall immediately vest in FAIC II upon such preparation or
possession. The Seller shall promptly deliver to the Indenture Trustee any
documents that come into its possession with respect to the Mortgage Loans
following the sale of the Mortgage Loans to FAIC II. Prior to such delivery, the
Seller shall hold any such documents for the benefit of FAIC II, its successors
and assigns.

         All documents with respect to any Mortgage Loan in the possession of
NMC following the execution by NMC of the Servicing Agreement shall be held by
NMC, in its capacity as Servicer, as bailee and agent for FAIC II, its
successors and assigns (including particularly the Issuer and the Indenture
Trustee), and shall only be released in accordance with the terms of the
Servicing Agreement.

         (b) Delivery of Mortgage Loan Files. Not later than two Business Days
prior to the Closing Date, the Seller shall deliver to the Indenture Trustee
each of the Mortgage Loan Documents required to be included in the Mortgage File
for each Mortgage Loan. The Mortgage Note for each Mortgage Loan shall be
endorsed without recourse to the Indenture Trustee and the Mortgage for each
Mortgage Loan shall be assigned to the Indenture Trustee. Each endorsement of a
Mortgage Note to the Indenture Trustee shall be in the following form:


                                WITHOUT RECOURSE,
                               PAY TO THE ORDER OF
                  NORWEST BANK MINNESOTA, NATIONAL ASSOCIATION,
                                   AS TRUSTEE


         Each assignment of a Mortgage relating to a Mortgage Loan shall be made
to "NORWEST BANK MINNESOTA, NATIONAL ASSOCIATION, AS TRUSTEE under an Indenture
w/Fund America Investors Trust 1998-NMC1 dated as of June 1, 1998."

         The Seller shall deliver the Mortgage Notes and the assignments of
Mortgage in recordable form to the Indenture Trustee endorsed and assigned in
blank, and the Indenture Trustee shall fill in the endorsements and assignments
as specified above by stamp. The Indenture Trustee shall return the completed
assignments of Mortgage to the Seller as soon as possible after the Closing Date
so the Seller can send them out for recording.

         Prior to the transfer and sale of the Mortgage Loans pursuant to this
Agreement, all Mortgage Loan Documents delivered to the Indenture Trustee shall
be held by the Indenture Trustee for the benefit of the Seller, and the
possession by the Indenture Trustee of such Mortgage Loan Documents will be at
the will of the Seller and will be in a custodial capacity only. Following the
transfer and sale of the Mortgage Loans from the Seller to FAIC II in accordance
with the terms 



                                       3
<PAGE>   4

and upon satisfaction of the conditions of this Agreement and until transfer of
the Mortgage Loans to the Issuer, the Indenture Trustee will hold all Mortgage
Loan Documents delivered to it hereunder for the benefit of FAIC II, as its
agent and bailee. The Indenture Trustee will act on FAIC II's behalf as a
custodian for the receipt and custody of all Mortgage Files during the period
described in the preceding sentence and, after the transfer of the Mortgage
Loans from FAIC II to the Issuer, the Indenture Trustee will hold all Mortgage
Loan Documents delivered to it hereunder as the agent of and custodian for the
Issuer until the Mortgage Loans are pledged by the Issuer to the Indenture
Trustee.

         (c) Examination of Mortgage Loan Documents; Acceptance of Mortgage
Loans. Prior to the Closing Date, the Seller shall either (1) deliver to FAIC II
or its designee in escrow, for examination, the Mortgage Loan Documents
pertaining to each Mortgage Loan, or (2) make such Mortgage Loan Documents
available to FAIC II or its designee for examination at the Seller's offices or
at such other place as the Seller shall specify. FAIC II, the Issuer, the
Indenture Trustee, or a designee of any such entity may review the Mortgage Loan
Documents.

         Prior to the Closing Date, the Indenture Trustee shall review the
documents delivered pursuant to Section 3(b) hereof as provided in Section
6.15(a) of the Indenture. An additional review shall be conducted by the
Indenture Trustee prior to the first anniversary of the Closing Date as provided
in Section 6.15(b) of the Indenture. If at any time FAIC II or the Indenture
Trustee discovers or receives notice that any Mortgage Loan Document is missing
or defective in any material respect with respect to any Mortgage Loan, or that
there exists any material discrepancy between the Mortgage Loan Documents and
the Mortgage Loan Schedule, it shall promptly notify the Seller in writing
thereof. Upon its receipt of notice of such incompleteness, defect or
discrepancy, the Seller shall cure, repurchase or substitute for the affected
Mortgage Loan to the extent provided in Section 7(b) hereof. At the time of any
such repurchase or substitution, the Indenture Trustee shall release documents
in its possession relating to such Mortgage Loan to the Seller. The fact that
FAIC II, the Indenture Trustee or a designee of either entity has conducted or
has failed to conduct any partial or complete examination of the Mortgage Loan
Documents shall not affect the rights of FAIC II, the Indenture Trustee (or any
assignee or successor of either of them) to demand repurchase or other relief as
provided herein.

         (d) Recordation of Assignments of Mortgage. Subject to the sale of the
Mortgage Loans by the Seller to FAIC II in accordance with the terms of this
Agreement, FAIC II hereby authorizes and instructs the Seller, and the Seller
hereby agrees, to record (or to cause one of its affiliates to record) all
assignments with respect to each Mortgage Loan required to be contained in the
Mortgage File pursuant to the Indenture in the public recording office for the
jurisdiction in which the related Mortgaged Property is located. All recording
fees relating to the recordation of the assignments as described above shall be
paid by the Seller or an affiliate of the Seller. Such assignments with respect
to each Mortgage Loan must be delivered to the recording office of the
appropriate jurisdiction within 60 days after the Closing Date, and the failure
of the related assignment to contain evidence of recording thereon within one
year after the Closing Date will constitute a defect for purposes of Section 7
below.

         SECTION 4.  Representations and Warranties of the Seller.

         (a) The Seller hereby represents and warrants to FAIC II as of the date
of this Agreement, or as of such other date as is specifically provided, as
follows:

                  (1) The Seller has been duly incorporated and is validly
         existing and in good standing under the laws of the State of Colorado
         and is duly qualified to do business and in good standing under the
         laws of each jurisdiction that requires such qualification wherein it
         owns or leases any material properties (except where the failure so to
         qualify would not have a material adverse effect on the Seller). The
         Seller has the full power and authority (corporate and other) to own
         its properties and conduct its business as its business is presently
         conducted.

                  (2) The Seller has the full power, authority and legal right
         to transfer and convey the Mortgage Loans to FAIC II, and has the full
         power, authority (corporate and other) and legal right to execute and
         deliver, engage in the transactions contemplated by, and perform and
         observe the terms and conditions of, this Agreement.

                  (3) This Agreement has been duly and validly authorized,
         executed and delivered by the Seller and (assuming the due
         authorization, execution and delivery hereof by FAIC II) constitutes
         the valid, legal and binding agreement of the Seller, enforceable
         against the Seller in accordance with its terms, subject to bankruptcy,
         insolvency, reorganization, receivership, moratorium or other similar
         laws affecting creditors' rights generally and to general principles of
         equity, regardless of whether such enforcement is sought in a
         proceeding in equity or at law.

                  (4) No consent, approval, authorization or order of or
         registration or filing with, or notice to, any governmental authority
         or court is required for the execution, delivery and performance of or
         compliance by the Seller with this Agreement or the consummation by the
         Seller of any other transaction contemplated hereby.

                  (5) Neither the execution and delivery of this Agreement by
         the Seller, nor the consummation by the Seller of the transactions
         herein contemplated, nor compliance with the provisions hereof by the
         Seller, will (A) conflict with or result in a breach of, or constitute
         a default under, any of the provisions of the Seller's articles of
         incorporation or by-laws, or any law, governmental rule or regulation,
         or any judgment, decree or order binding on the Seller or any of its
         properties, or any of the provisions of any indenture, mortgage, deed
         of trust, contract or other instrument to which the Seller is a party
         or by which the Seller is bound or (B) result in the creation or
         imposition of any lien, charge or encumbrance which would have a
         material adverse effect upon any of the Seller's properties pursuant to
         the terms of any such indenture, mortgage, deed of trust, contract or
         other instrument.

                  (6) The Seller is not, and with passage of time does not
         expect to become, insolvent or bankrupt.



                                       5
<PAGE>   6


                  (7) There are no actions, suits, proceedings or investigations
         pending or, to the Seller's knowledge, threatened against the Seller
         that should reasonably be expected to affect adversely the transfer of
         the Mortgage Loans, the issuance of the Bonds, or the execution,
         delivery, performance or enforceability of this Agreement or have a
         material adverse effect on the financial condition of the Seller.

                  (8) The Seller is, and, immediately prior to the sale of the
         Mortgage Loans to FAIC II, the Seller will be, the sole owner of, and
         will have good, indefeasible and marketable title to, the Mortgage
         Loans, subject to no prior lien, mortgage, security interest, pledge,
         charge or other encumbrance, except any lien to be released prior to or
         concurrently with the purchase of the Mortgage Loans by FAIC II.
         Following the sale of the Mortgage Loans, FAIC II or the Issuer as FAIC
         II's transferee will own such Mortgage Loans, free and clear of any
         prior lien, mortgage, security interest, pledge, charge or other
         encumbrance (assuming that an Assignment of the related Mortgage from
         the Seller to FAIC II, or its designee, is recorded), except the lien
         created by the Indenture.

         (b)

                  (1) As to each Mortgage Loan, the Seller hereby represents and
         warrants to FAIC II as of the date of this Agreement, or as of such
         other date as is specifically provided, that each representation and
         warranty set forth in Exhibit B hereto is true and correct.

                  (2) The Seller has not dealt with any broker, investment
         banker, agent or other person that may be entitled to any commission or
         compensation in connection with the sale of the Mortgage Loans to FAIC
         II.

                  (3) With respect to each Mortgage Loan, the Seller is in
         possession of each of the Mortgage Loan Documents required to be
         included in the related Mortgage File (except to the extent such
         Mortgage File has been delivered to the Indenture Trustee as described
         in this Agreement).

                  (4) The transfer, assignment and conveyance of the Mortgage
         Loans by the Seller pursuant to this Agreement are not subject to the
         bulk transfer or any similar statutory provisions in effect in any
         applicable jurisdiction.

                  (5) The Seller used no adverse selection procedures in
         selecting the Mortgage Loans that identified the Mortgage Loans as
         being less desirable or valuable than other mortgage loans in its
         portfolio as to which the representations and warranties required by
         this Agreement could truthfully be made. The Mortgage Loans are
         representative of the Seller's portfolio of adjustable-rate residential
         mortgage loans.

                  (6) The description of those Mortgage Loans set forth in the
         Prospectus Supplement under the heading "Description of the Mortgage
         Pool" does not contain any untrue statement of any material fact or
         omit any material fact required to be stated therein or necessary in
         order to make the statements contained therein, in light of the
         circumstances under which they are made, not misleading.



                                       6
<PAGE>   7

                  (7) The information set forth in the Mortgage Loan Schedule
         hereto is true and correct in all material respects in the case of each
         Mortgage Loan, as of its respective Cut-off Date.

                  (8) The consideration received by the Seller upon the sale of
         the Mortgage Loans under this Agreement constitutes fair consideration
         and reasonably equivalent value for the Mortgage Loans.

                  (9) The Seller is solvent, and the sale of the Mortgage Loans
         as contemplated hereby will not cause the Seller to become insolvent.
         The sale of the Mortgage Loans is not undertaken with the intent to
         hinder, delay or defraud any of the Seller's creditors.

                  (10) The Seller intends to relinquish all rights to possess,
         control and monitor the Mortgage Loans sold pursuant to this Agreement
         (except such rights as are entailed in its serving as the Servicer of
         the Mortgage Loans under the Servicing Agreement). After the Closing
         Date, the Seller will have no right to modify or alter the terms of the
         sale of the Mortgage Loans (except such rights as are entailed in its
         serving as the Servicer of the Mortgage Loans under the Servicing
         Agreement), and the Seller will have no right or obligation to
         repurchase any Mortgage Loan or substitute another mortgage loan for
         any Mortgage Loan sold hereunder, except as provided in Sections 3 and
         7 hereof.

         SECTION 5. Representations and Warranties of FAIC II. FAIC II hereby
represents and warrants to the Seller as of the date of this Agreement, or as of
such other date as is specifically provided, as follows:

         (a) FAIC II is a corporation duly organized and validly existing in
good standing under the laws of the State of Delaware.

         (b) FAIC II has the full power, authority (corporate and other) and
legal right to execute and deliver, engage in the transactions contemplated by,
and perform and observe the terms and conditions of, this Agreement.

         (c) This Agreement has been duly and validly authorized, executed and
delivered by FAIC II, and (assuming the due authorization, execution and
delivery hereof by the Seller) constitutes the valid, legal and binding
agreement of FAIC II, enforceable against FAIC II in accordance with its terms,
subject to bankruptcy, insolvency, reorganization, receivership, moratorium or
other similar laws affecting creditors' rights generally and to general
principles of equity, regardless of whether such enforcement is sought in a
proceeding in equity or at law.

         (d) No consent, approval, authorization or order of or registration or
filing with, or notice to, any governmental authority or court is required, for
the execution, delivery and performance of or compliance by FAIC II with this
Agreement or the consummation by FAIC II of any other transaction contemplated
hereby.



                                       7

         (e) Neither the execution and delivery of this Agreement by FAIC II,
nor the consummation by FAIC II of the transactions hereby contemplated, nor
compliance with the provisions hereof by FAIC II, will (i) conflict with or
result in a breach of, or constitute a default under, any of the provisions of
FAIC II's certificate of incorporation or by-laws, or any law, governmental rule
or regulation, or any judgment, decree or order binding on FAIC II or any of its
properties, or any of the provisions of any contract or other instrument to
which FAIC II is a party or by which it is bound or (ii) result in the creation
or imposition of any lien, charge or encumbrance which would have a material
adverse effect upon the Bonds.

         (f) There are no actions, suits, proceedings or investigations pending
or, to FAIC II's knowledge, threatened against FAIC II that should reasonably be
expected to affect adversely the execution, delivery, performance or
enforceability of this Agreement or have a material adverse effect on the
financial condition of FAIC II.

         SECTION 6.  Covenants of the Seller.  The Seller hereby covenants to
FAIC II as follows:

         (a) On or before the Closing Date, the Seller shall execute and deliver
a Secretary's or Assistant Secretary's Certificate evidencing the Seller's
authority to enter into the transactions contemplated by this Agreement.

         (b) On or before the Closing Date, the Seller shall take all steps
reasonably required of it to effect the transfer of the Mortgage Loans to the
Issuer and the pledge of the Mortgage Loans to the Indenture Trustee, free and
clear of any lien, charge, or encumbrance except the lien evidenced by the
Indenture.

         (c) The Seller shall use its best efforts to make available to counsel
for FAIC II in executed form each of the Closing Documents (as defined in
Section 9(b) below) on or before the Closing Date, it being understood that such
documents are to be released and delivered only on the closing of the
transaction contemplated hereby and the sale of the Bonds.

         (d) In the event the Seller fails to take all actions necessary to
effect the conveyance of the Mortgage Loans to FAIC II on or before the Closing
Date as contemplated hereby, the Seller hereby constitutes and appoints FAIC II
and its officers and representatives as the Seller's true and lawful
attorneys-in-fact to do all acts and transactions and to execute and deliver all
agreements, documents, instruments and papers by and on behalf of the Seller as
may be necessary to consummate the transfer of the Mortgage Loans to FAIC II.
The foregoing grant of authority shall be deemed to be irrevocable and a power
coupled with an interest.

         (e) Other than general solicitations, the Seller shall not solicit any
Mortgagor to refinance its Mortgage Loan until the earlier of (i) the expiration
of the period, if any, in which a prepayment penalty is required to be paid or
(ii) receiving evidence that the Mortgagor intends to refinance its Mortgage
Loan.

         (f) The Seller will use its best efforts to qualify and remain
qualified as a real estate investment trust ("REIT") under Section 856 of the
Code and to cause any subsidiary owning interests in the Issuer to be a
"qualified REIT subsidiary" (as defined in Section 856(i) of the Code).



                                       8
<PAGE>   9

The Seller agrees to transfer the Trust Certificates to another REIT by December
31, 1998 if it is unable to complete an initial public offering in 1998.

         SECTION 7.  Repurchase Obligations.

         (a) Each of the representations and warranties made by the Seller
herein shall survive the purchase by FAIC II of the Mortgage Loans and shall
continue in full force and effect, notwithstanding any restrictive or qualified
endorsement on the Mortgage Notes and notwithstanding subsequent termination of
this Agreement, the Trust Agreement or the Indenture. The Seller's
representations and warranties shall not be impaired by any review or
examination of Mortgage Loan Documents or other documents evidencing or relating
to the Mortgage Loans or any failure on the part of FAIC II to review or examine
such documents and shall inure to the benefit of the Issuer and the Indenture
Trustee (as the assignees of FAIC II) for the benefit of the Bondholders. With
respect to the representations and warranties contained herein 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 either the Seller, FAIC II, or the Indenture 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 and warranty was made, the Seller shall take action in accordance
with the following paragraph in respect of such Mortgage Loan.

         (b) Upon discovery or receipt of notice by the Seller, FAIC II or the
Indenture Trustee of any missing or materially defective document in any
Mortgage File, a breach of any of the representations and warranties set forth
in Section 4 hereof or in Exhibit B hereto, or a default in the performance of
any of the covenants or other obligations of the Seller under this Agreement,
that in any of the foregoing cases materially and adversely affects the value of
any Mortgage Loan or the interest therein of FAIC II, the Issuer, the Indenture
Trustee or the Bondholders, the party discovering or receiving notice of the
missing or materially defective document, breach, or default shall give prompt
written notice to the other parties and to the Underwriter. Upon its discovery
or its receipt of notice of any such missing or materially defective
documentation or any such breach of a representation and warranty or covenant,
the Seller shall, within 60 days after such discovery or receipt of such notice,
either (i) cure such defect or breach in all material respects, or (ii) either
repurchase the affected Mortgage Loan at the Purchase Price therefor or
substitute one or more Qualified Replacement Mortgage Loans for the related
Mortgage Loan. The Seller shall amend the Mortgage Loan Schedule to reflect the
withdrawal of any Mortgage Loan from the terms of this Agreement, the Trust
Agreement and the Indenture and the addition, if any, of any Qualified
Replacement Mortgage Loan(s). In order to effect a substitution pursuant to this
Section 7(b), the Seller will deliver to the Indenture Trustee (i) each of the
Mortgage Loan Documents required to be contained in the Mortgage File with
respect to the Qualified Replacement Mortgage Loan(s) and (ii) if the aggregate
Principal Balance on the date of substitution of the Qualified Replacement
Mortgage Loan(s) is less than the Principal Balance of the replaced Mortgage
Loan (after application of Monthly Payments due in the month of substitution),
cash in an amount equal to such shortfall plus 30 days' interest at the Mortgage
Interest Rate on the amount of such shortfall. The Indenture


                                       9
<PAGE>   10

Trustee shall deposit any such cash into the Bond Account. Any repurchase of a
Mortgage Loan pursuant to this Section 7(b) shall be accomplished by the
delivery to the Indenture Trustee, on (or determined as of) the last day of the
calendar month in which such repurchase is made, of the Purchase Price for such
Mortgage Loan (such delivery may be made on or before the Deposit Date in the
month following such calendar month).

         (c) It is understood and agreed that the obligations of the Seller set
forth in this Section 7 to cure, repurchase or substitute for a Mortgage Loan
and to indemnify FAIC II as provided in Section 8 of this Agreement constitute
the sole remedies of FAIC II, the Issuer and the Indenture Trustee against the
Seller with respect to a missing or materially defective document in any
Mortgage File, a breach of representations and warranties of the Seller set
forth in Section 4 hereof or in Exhibit B hereto, or a default in the
performance by the Seller of any of its covenants or other obligations under
this Agreement.

         SECTION 8.  Indemnification.

         (a) In the event the Seller breaches its representations, warranties,
covenants or obligations set forth herein, the Seller shall indemnify and hold
harmless FAIC II (and its assignees in accordance with Section 17 hereof) (the
"Indemnified Parties") from and against any losses, damages, penalties, fines,
forfeitures, legal fees and related costs, judgments, and other costs and
expenses resulting from any claim, demand, defense or assertion based on or
grounded upon, or resulting from, such breach. Promptly after receipt by an
Indemnified Party of notice of the commencement of any such action, such
Indemnified Party will notify the Seller in writing of the commencement thereof
if a claim in respect of such action is to be made against the Seller under this
Section 8, but the omission so to notify the Seller will not relieve the Seller
from any liability hereunder unless such omission materially prejudices the
rights and positions of the Seller. If any such action is brought against an
Indemnified Party, and it notifies the Seller of the commencement thereof, the
Seller will be entitled to participate therein, and to assume the defense
thereof, with counsel selected by the Seller and reasonably satisfactory to such
Indemnified Party, and after notice from the Seller to the Indemnified Party of
its election so to assume the defense thereof, the Seller will not be liable to
the Indemnified Party under this Section 8 for any legal or other expenses
subsequently incurred by such Indemnified Party in connection with the defense
of such action; provided, however, that this sentence shall not be in effect if
(1) the Seller shall not have employed counsel reasonably satisfactory to the
Indemnified Party to represent the Indemnified Party within a reasonable time
after notice of commencement of the action or (2) the Seller shall have
authorized the employment of counsel for the Indemnified Party at the expense of
the Seller. If the Seller assumes the defense of any such proceeding, it shall
be entitled to settle such proceeding with the consent of any Indemnified Party
that is also subject to such proceeding or, if such settlement provides for
release of any such Indemnified Party in connection with all matters relating to
the proceeding which have been asserted against such Indemnified Party in such
proceeding by the other parties to such settlement, without the consent of such
Indemnified Party.

         (b) The Seller shall reimburse the Underwriter upon demand for all
amounts otherwise payable by FAIC II pursuant to the indemnification provisions
in the Underwriting Agreement, in the event that any breach referred to in the
preceding paragraph or any of the following results in the inability of the
parties hereto to consummate the transactions contemplated herein: (1) failure
to obtain any consent or authorization, if any, required under federal or
applicable state law for the



                                       10
<PAGE>   11

Seller to perform the transactions contemplated herein; or (2) the Seller's
failure to perform any of the obligations of the Seller under Section 9(a), (b),
(c) or (d) hereof.

         (c) In the event of a breach by the Underwriter of its obligation to
purchase the Bonds pursuant to the Underwriting Agreement, subject to payment in
full of the Issuance Fee (as defined in Section 10 below) to FAIC II, FAIC II
hereby assigns to the Seller any and all rights of action or other claims FAIC
II may have against the Underwriter pursuant to the Underwriting Agreement
(other than FAIC II's right to receive payment due FAIC II from the Underwriter
for FAIC II's expenses related to the proposed issuance of the Bonds); provided,
however, that FAIC II expressly reserves, and does not hereby assign, its rights
to indemnification and contribution under the Underwriting Agreement and any
other rights to indemnification or contribution it may have at law or in equity.

         SECTION 9.  Conditions to Obligation of FAIC II. The obligation of FAIC
II hereunder to purchase the Mortgage Loans is subject to the following
conditions:

         (a) The accuracy in all material respects of all of the representations
and warranties of the Seller under this Agreement and the non-occurrence of any
event which, with notice or the passage of time, would constitute a default
under this Agreement;

         (b) FAIC II shall have received, or FAIC II's attorneys shall have
received, in escrow (to be released from escrow at the time of closing), the
following documents (collectively, the "Closing Documents") in such forms as are
agreed upon and acceptable to FAIC II, duly executed by all signatories other
than FAIC II as required pursuant to the respective terms thereof:

                           (i)   A Bill of Sale substantially in the form of
                  Exhibit A hereto;

                           (ii)  An opinion of counsel for the Seller as to
                  various corporate matters and such other opinions of counsel
                  as are necessary in order to obtain the ratings set forth in
                  Section 9(f) below, each of which shall be acceptable to FAIC
                  II, its counsel, the Seller, its counsel, and Fitch IBCA, Inc.
                  ("Fitch") and Standard & Poor's Ratings Services, a division
                  of The McGraw-Hill Companies, Inc. ("S&P" and together with
                  Fitch, the "Rating Agencies") (it being understood that such
                  opinions shall expressly provide that the Indenture Trustee
                  shall be entitled to rely on such opinions of counsel); and

                           (iii) From Deloitte & Touche LLP, certified public
                  accountants, comfort letters as required by the Underwriting
                  Agreement;

         (c) The Seller shall have delivered to the Indenture Trustee, in
escrow, all documents required to be delivered hereunder and shall have released
its interest therein to FAIC II or its designee;

         (d) Compliance by the Seller with all other terms and conditions of 
this Agreement;



                                       11
<PAGE>   12

         (e) The purchase by the Underwriter of the Bonds pursuant to the terms
of the Underwriting Agreement; and

         (f) The receipt of written confirmation from Fitch and S&P that they
have assigned the Class A Bonds a rating of "AAA", the Class M-1 Bonds a rating
of at least "AA" and the Class M-2 Bonds a rating of at least "A", and written
confirmation from Fitch that it has assigned the Class M-3 Bonds a rating of at
least "BBB".

         SECTION 10. Fees and Deposits. The Seller shall be responsible for
payment of (1) all fees and expenses of accountants, printers, the Owner Trustee
and the Indenture Trustee in connection with the issuance of the Bonds,
including the fees of their respective attorneys, including such fees and
expenses associated with loan file due diligence review, (2) the fees incurred
by FAIC II in connection with the establishment of the registration statement
with respect to the Bonds, including fees payable to the Securities and Exchange
Commission with respect to the Bonds and FAIC II's related fees and expenses for
attorneys and accountants, (3) the fees and expenses payable to the Rating
Agencies for their initial ratings of the Bonds, including the fees of their
respective attorneys, and (4) the payment of an issuance fee (the "Issuance
Fee") of $75,000 to FAIC II for the use of its services in connection with the
issuance of the Bonds. In addition, the Seller shall pay the fees and expenses
of its and FAIC II's attorneys and accountants in connection with the issuance
of the Bonds.

         SECTION 11. Mandatory Delivery; Grant of Security Interest. The sale
and delivery on the Closing Date of the Mortgage Loans described in the Mortgage
Loan Schedule are mandatory, it being specifically understood and agreed that
each Mortgage Loan is unique and identifiable on the Closing Date and that an
award of money damages would be insufficient to compensate FAIC II for the
losses and damages that would be incurred by FAIC II in the event of the
Seller's failure to deliver the Mortgage Loans on or before the Closing Date.
The Seller hereby grants to FAIC II a first lien on and a continuing first
priority security interest in each Mortgage Loan and each document and
instrument evidencing each Mortgage Loan to secure the performance by the Seller
of its obligation to deliver such Mortgage Loans hereunder. All rights and
remedies of FAIC II under this Agreement are distinct from, and cumulative with,
any other rights or remedies under this Agreement or afforded by law or equity,
and all such rights and remedies may be exercised concurrently, independently or
successively.

         SECTION 12. Notices. All demands, notices and communications hereunder
shall be in writing and shall be deemed to have been duly given if personally
delivered or mailed by registered mail, postage prepaid, or transmitted by
telecopier, telex or telegraph and confirmed by a similar mailed writing, to the
following:

to be sent by giving notice of such change of address in conformity with the
provisions of this Section 12 for the giving of notice.

         SECTION 13. Severability of Provisions. Any part, provision,
representation, warranty or covenant contained in this Agreement that is
prohibited or unenforceable or that is held to be void or unenforceable in any
jurisdiction shall, as to such jurisdiction, be ineffective to the extent of
such prohibition or unenforceability without invalidating the remaining
provisions hereof, and any such prohibition or unenforceability in any
jurisdiction as to any Mortgage Loan shall not invalidate or render
unenforceable such provision in any other jurisdiction. To the extent permitted
by applicable law, the parties hereto waive any provision of law that prohibits
or renders void or unenforceable any provision hereof.


                                       13
<PAGE>   14


         SECTION 14. Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK, NOTWITHSTANDING
ANY NEW YORK OR OTHER CONFLICT OF LAWS PROVISION TO THE CONTRARY.

         SECTION 15. Agreement of the Seller. The Seller agrees to execute and
deliver such instruments and take such actions as FAIC II, the Issuer or the
Indenture Trustee may, from time to time, reasonably request in order to
effectuate the purpose and to carry out the terms of this Agreement including,
without limitation, the execution and filing of any UCC financing statements to
evidence the interests of FAIC II and any of its transferees in the Mortgage
Loans and other assets pledged to the Indenture Trustee.

         SECTION 16. Survival. The Seller agrees that the representations,
warranties and agreements made by it herein and in any certificate or other
instrument delivered pursuant hereto shall be deemed to have been relied upon by
FAIC II, notwithstanding any investigation heretofore or hereafter made by FAIC
II or on FAIC II's behalf, and that the representations, warranties and
agreements made by the Seller herein or in any such certificate or other
instrument shall survive the delivery of and payment for the Mortgage Loans.

         SECTION 17. Assignment; Third Party Beneficiaries. The Seller hereby
acknowledges that FAIC II will assign all its rights hereunder (except those
rights set forth in Section 8(b) and Section 10 hereof) to the Issuer, which
will in turn pledge all of the rights hereunder to the Indenture Trustee. The
Seller agrees that, upon the execution of the Indenture, the Indenture Trustee
will have all such rights and remedies provided to FAIC II hereunder (except
those rights set forth in Section 8(b) and Section 10 hereof) and this Agreement
will inure to the benefit of the Indenture Trustee for the benefit of the
Bondholders.

         The Indenture Trustee shall constitute not only an assignee of FAIC
II's rights in accordance with this Section 17 but also an intended third-party
beneficiary of this Agreement to the extent necessary to enforce such rights and
to obtain the benefit of such remedies.

         SECTION 18. Miscellaneous.

         (a) This Agreement may be executed in two or more counterparts, each of
which when so executed and delivered shall be an original, but all of which
together shall constitute one and the same instrument. This Agreement shall
inure to the benefit of, and be binding upon, the parties hereto and their
respective successors and assigns.

         (b) Any person into which the Seller may be merged or consolidated or
any person resulting from a merger or consolidation involving the Seller or any
person succeeding to the business of the Seller shall be considered the
successor of the Seller hereunder, without the further act or consent of either
party hereto. Except as provided above, this Agreement cannot be assigned,



                                       14
<PAGE>   15

pledged or hypothecated by any party without the written consent of each other
party to this Agreement.

         (c) This Agreement supersedes all prior agreements and understandings
between the parties hereto relating to the subject matter hereof. Neither this
Agreement nor any term hereof may be changed, waived, discharged or terminated
orally, but only by an instrument in writing signed by the party against whom
enforcement of the change, waiver, discharge or termination is sought. The
headings in this Agreement are for purposes of reference only and shall not
limit or otherwise affect the meaning of the provisions of this Agreement.

         (d) FAIC II shall immediately deliver the Mortgage Loans and all
related Mortgage Loan Documents to the Seller or the Seller's designee and any
security interest created by Section 11 hereof shall be deemed to have been
released if, on the Closing Date, each of the conditions set forth in Section 9
hereof shall not have been satisfied or waived.

         (e) It is the express intent of the parties hereto that the conveyance
of the Mortgage Loans by the Seller to FAIC II as contemplated by this Agreement
be construed as a sale of the Mortgage Loans by the Seller to FAIC II. It is,
further, not the intention of the parties that such conveyance be deemed a
pledge of the Mortgage Loans by the Seller to FAIC II or any assignee of FAIC
II, including, but not limited to, the Indenture Trustee, to secure a debt or
other obligation of the Seller. However, in the event that, notwithstanding the
intent of the parties hereto, the Mortgage Loans are held to be property of the
Seller, then (i) this Agreement shall also be deemed to be a security agreement
within the meaning of Article 9 of the New York Uniform Commercial Code; (ii)
the conveyance provided for herein shall be deemed to be a grant by the Seller
to FAIC II of a first priority security interest in all of the Seller's right,
title and interest in and to the Mortgage Loans and all amounts payable to the
holder of the Mortgage Loans in accordance with the terms thereof and all
proceeds of the conversion, voluntary or involuntary, of the foregoing into
cash, instruments, securities, or other property, including without limitation
all amounts, other than investment earnings, from time to time held or invested
in the Bond Account or the Collection Account, whether in the form of cash,
instruments, securities or other property; (iii) the possession by FAIC II or
its agents of items of property that constitute instruments, money, negotiable
documents or chattel paper shall be deemed to be "possession by the secured
party" for purposes of perfecting the security interest pursuant to Section
9-305 of the New York Uniform Commercial Code, and (iv) notifications to persons
holding such property, and acknowledgments, receipts or confirmations from
persons holding such property, shall be deemed notifications to, or
acknowledgments, receipts or confirmations from, financial intermediaries,
bailees or agents (as applicable) of FAIC II for the purpose of perfecting such
security interest under applicable law. Any assignment of the interest of FAIC
II pursuant to any provision hereof shall also be deemed to be an assignment of
any security interest created hereby. The Seller and FAIC II shall, to the
extent consistent with this Agreement, take such actions as may be necessary to
ensure that, if this Agreement were deemed to create a security interest in the
Mortgage Loans, such security interest would be deemed to be a perfected
security interest of first priority under applicable law and would be maintained
as such throughout the terms of this Agreement and the Indenture.

           (iv)  to enter into and perform its obligations under the Basic
      Documents to which it is or is to be a party;

           (v)   to engage in those activities, including entering into

      foregoing or are incidental thereto or connected therewith;

           (vi)  subject to compliance with the Basic Documents, to engage in

      of the Owner Trust Estate and the making of distributions and payments to
      the Holders and the Bondholders; and

           (vii) to issue the Certificates pursuant to this Agreement.

The Trust is hereby authorized by the initial Certificateholders to engage in

obligations of the Trust under the Basic Documents. It is the intention of the
parties hereto that the Trust constitute a business trust under the Business
Trust Statute and that this Agreement constitute the governing instrument of
such business trust. It is the intention of the parties hereto that, solely for
income and franchise tax purposes, after issuance of the Certificates, the Trust
shall be treated as a partnership, with the assets of the partnership being the
Mortgage Loans and other assets held by the Trust, the partners of the
partnership being the holders of the Certificates and the Bonds being
non-recourse debt of the partnership (or, if there is only one
Certificateholder, that the Trust shall be disregarded as an entity separate
from such Holder, with the assets held by the Trust being treated as assets of
the Holder and the Bonds being treated as non-recourse debt of the Holder).
Furthermore, it is the intention of the parties hereto that, at all times while
the Bonds are outstanding, 100% of the Certificates will be owned by a real
estate investment trust ("REIT") as defined in Section 856 of the Code or one or
more "qualified REIT subsidiaries" (as defined in Section 856(i) of the Code) of
such REIT. The parties agree that, unless otherwise required by appropriate tax
authorities or unless the Trust is disregarded as an entity separate from its
sole Certificateholder for income and franchise tax purposes, the Owner Trustee
will file or cause to be filed annual or other necessary returns, reports and
other forms consistent with the characterization of the Trust as a partnership
for such tax purposes pursuant to Section 2.11(k). The parties agree that no
election will be made to treat the Trust or the Owner Trust Estate as a real
estate mortgage investment conduit as defined in Section 860D of the Code.
Effective as of the date hereof, the Owner Trustee shall have all rights, powers
and duties set forth herein and in the Business Trust Statute with respect to
accomplishing the purposes of the Trust. The Owner Trustee shall file the
Certificate of Trust with the Secretary of State.

     SECTION 2.7. Liability of the Holders.  No Holder shall have any personal
liability for any liability or obligation of the Trust.  The Certificates shall
be fully paid and non-assessable.

     SECTION 2.8. Title to Trust Property.

         (a) Subject to the Indenture, legal title to all of the Owner Trust
Estate shall be vested at all times in the Trust as a separate legal entity
except where applicable law in any jurisdiction requires title to any part of
the Owner Trust Estate to be vested in a trustee or trustees, in which case
title shall be deemed to be vested in the Owner Trustee and/or a separate
trustee, as the case may be.

         (b) The Certificateholders shall not have legal title to any part of
the Owner Trust Estate. No transfer by operation of law or otherwise of any
interest of the Certificateholders shall operate to terminate this Agreement or
the trusts hereunder or entitle any transferee to an Accounting or to the
transfer to it of any part of the Owner Trust Estate.

partnership (rather than disregarded as a separate entity) for federal income
tax purposes pursuant to Section 2.6, the following provisions shall apply:

         (a) A separate capital account (a "Capital Account") shall be
established and maintained for each Certificateholder in accordance with
Treasury Regulations Section 1.704-1(b)(2)(iv). No Certificateholder shall be
entitled to interest on its Capital Account or any capital contribution made by
such Holder to the Trust.

         (b) Upon termination of the Trust pursuant to Article IX, any amounts
available for distribution to Holders shall be distributed to the Holders with
positive Capital Account balances in accordance with such balances. For purposes
of this Section 2.11(b), the Capital Account of each Holder shall be determined
after all adjustments made in accordance with this Section 2.11 resulting from
the Trust's operations and from all sales and dispositions of all or any part of
the assets of the Trust. Any distributions pursuant to this Section 2.11(b)
shall be made by the end of the Taxable Year in which the termination occurs
(or, if later, within 90 days after the date of the termination).

         (c) No Certificateholder shall be required to restore any deficit
balance in its Capital Account. Furthermore, no Holder shall be liable for the
return of the Capital Account of, or of any capital contribution made to the
Trust by, another Holder.

         (d) Profit and loss of the Trust for each Taxable Year shall be
allocated to the Certificateholders in accordance with their respective
Percentage Interests.

         (e) Notwithstanding any provision to the contrary, (i) any expense of
the Trust that is a "nonrecourse deduction" within the meaning of Treasury
Regulations Section 1.704-2(b)(1) shall be allocated in accordance with the
Holders' respective Percentage Interests, (ii) any expense of the Trust that is
a "partner nonrecourse deduction" within the meaning of Treasury Regulations
Section 1.704-2(i)(2) shall be allocated in accordance with Treasury Regulations
Section 1.704-2(i)(1), (iii) if there is a net decrease in Trust Minimum Gain
within the meaning of Treasury Regulations Section 1.704-2(f)(1) for any Taxable
Year, items of gain and income shall be allocated among the Holders in
accordance with Treasury Regulations Section 1.704-2(f) and the ordering rules
contained in Treasury Regulations Section 1.704-2(j), and (iv) if there is a net
decrease in Holder Nonrecourse Debt Minimum Gain within the meaning of Treasury
Regulations Section 1.704-2(i)(4) for any Taxable Year, items of gain and income
shall be 


                                       9
<PAGE>   14

allocated among the Holders in accordance with Treasury Regulations
Section 1.704-2(i)(4) and the ordering rules contained in Treasury Regulations
Section 1.704-2(j). A Holder's "interest in partnership profits" for purposes of
determining its share of the nonrecourse liabilities of the Trust within the
meaning of Treasury Regulations Section 1.752-3(a)(3) shall be such Holder's
Percentage Interest.

         (f) If a Holder receives in any Taxable Year an adjustment, allocation,
or distribution described in subparagraphs (4), (5), or (6) of Treasury
Regulations Section 1.704-1(b)(2)(ii)(d) that causes or increases a negative
balance in such Holder's Capital Account that exceeds the sum of such Holder's
shares of Trust Minimum Gain and Holder Nonrecourse Debt Minimum Gain, as
determined in accordance with Treasury Regulations Sections 1.704-2(g) and
1.704-2(i), such Holder shall be allocated specially for such Taxable Year (and,
if necessary, later Taxable Years) items of income and gain in an amount and
manner sufficient to eliminate such negative Capital Account balance as quickly
as possible as provided in Treasury Regulations Section 1.704-1(b)(2)(ii)(d).
After the occurrence of an allocation of income or gain to a Holder in
accordance with this Section 2.11(f), to the extent permitted by Regulations
Section 1.704-1(b), items of expense or loss shall be allocated to such Holder
in an amount necessary to offset the income or gain previously allocated to such
Holder under this Section 2.11(f).

         (g) Loss shall not be allocated to a Holder to the extent that such
allocation would cause a deficit in such Holder's Capital Account (after
reduction to reflect the items described in Treasury Regulations Section
1.704-1(b)(2)(ii)(d)(4), (5) and (6)) to exceed the sum of such Holder's shares
of Trust Minimum Gain and Holder Nonrecourse Debt Minimum Gain. Any loss in
excess of that limitation shall be allocated to all the Holders in accordance
with their respective Percentage Interests. After the occurrence of an
allocation of loss to a Holder in accordance with this Section 2.11(g), to the
extent permitted by Treasury Regulations Section 1.704-1(b), profit shall be
allocated to such Holder in an amount necessary to offset the loss previously
allocated to such Holder under this Section 2.11(g).

         (h) If a Holder transfers any part or all of its Holdership Interest
and the transferee is admitted as provided herein (a "Transferee Holder"), the
distributive shares of the various items of profit and loss allocable among the
Holders during such Taxable Year shall be allocated between the transferor and
the Transferee Holder (at the election of the Holders (including the transferor,
but excluding the Transferee Holder)) either (i) as if the Taxable Year had
ended on the date of the transfer or (ii) based on the number of days of such
Taxable Year that each was a Holder without regard to the results of Trust
activities in the respective portions of such Taxable Year in which the
transferor and Transferee Holder were Holders.

         (i) "Profit" and "loss" and any items of income, gain, expense or loss
referred to in this Section 2.11 shall be determined in accordance with federal
income tax accounting principles as modified by Treasury Regulations Section
1.704-1(b)(2)(iv), except that profits and losses shall not include items of
income, gain, and expense that are specially allocated pursuant to Sections
2.11(e), 2.11(f) or 2.11(g) hereof. All allocations of income, profits, gains,
expenses, and losses (and all items contained therein) for federal income tax
purposes shall be identical to



                                       10
<PAGE>   15

all allocations of such items set forth in this Section 2.11, except as
otherwise required by Section 704(c) of the Code and Section 1.704-1(b)(4) of
the Treasury Regulations.

         (j) The taxable year of the Trust (the "Taxable Year") shall be the
calendar year or such other taxable year as may be required by Section 706(b) of
the Code.

         (k) At the Trust's expense, the Owner Trustee shall (i) prepare, or
cause to be prepared, and file such tax returns relating to the Trust (including
a partnership information return, IRS Form 1065) as are required by applicable
federal, state, and local law, (ii) cause such returns to be signed in the
manner required by law, (iii) make such elections as may from time to time be
required or appropriate under any applicable law so as to maintain the Trust's
classification as a partnership for tax purposes, (iv) prepare and deliver, or
cause to be prepared and delivered, to the Holders, no later than 75 days after
the close of each Taxable Year, a Schedule K-1, a copy of the Trust's
informational tax return (IRS Form 1065), and such other reports (collectively,
the "Annual Tax Reports") setting forth in sufficient detail all such
information and data with respect to the transactions effected by or involving
the Trust during such Taxable Year as shall enable the each Holder to prepare
its federal, state, and local income tax returns in accordance with the laws
then prevailing, and (v) collect, or cause to be collected, any withholding tax
as described in Section 5.2(c) with respect to income or distributions to
Certificateholders.

         (l) The Holders shall designate a Holder as the tax matters partner for
the Trust within the meaning of Section 6231(a)(7) of the Code (the Tax Matters
Partner"), and shall notify the Indenture Trustee, the Manager (as defined in
Section 5.2(d)) and the Owner Trustee in writing of the name and address of such
Tax Matters Partner. The Tax Matters Partner shall have the right and obligation
to take all actions authorized and required, respectively, by the Code for the
Tax Matters Partner. The Tax Matters Partner shall have the right to retain
professional assistance in respect of any audit or controversy proceeding
initiated with respect to the Trust by the Internal Revenue Service or any state
or local taxing authority, and all expenses and fees incurred by the Tax Matters
Partner on behalf of the Trust shall constitute expenses of the Trust. In the
event the Tax Matters Partner receives notice of a final partnership adjustment
under Section 6223(a)(2) of the Code, the Tax Matters Partner shall either (i)

                                  ARTICLE III

                     CERTIFICATES AND TRANSFER OF INTERESTS

     SECTION 3.1. Initial Ownership.  Upon the formation of the Trust by the
contribution by the Company pursuant to Section 2.5 and until the issuance of
the Certificates, the Company shall be the sole beneficiary of the Trust.

     SECTION 3.2. The Certificates.  The Certificates shall be issued without a
principal amount and shall evidence beneficial ownership interests in the Trust.
The Certificates shall be printed, lithographed or engraved or may be produced
in any other manner as is reasonably acceptable to the Owner Trustee, as
evidenced by its execution thereof. The Certificates shall be executed on behalf
of the Trust by manual or facsimile signature of a Trust Officer of the Owner
Trustee. Certificates bearing the manual or facsimile signatures of individuals
who were, at the time when such signatures shall have been affixed, authorized
to sign on behalf of the Trust, shall be valid, notwithstanding that such
individuals or any of them shall 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 authentication and delivery of such Certificates.

     A transferee of a Certificate shall become a Certificateholder, and shall
be entitled to the rights and subject to the obligations of a Certificateholder
hereunder upon such transferee's acceptance of a Certificate duly registered in
such transferee's name pursuant to Section 3.4.

     SECTION 3.3. Execution, Authentication and Delivery of Trust Certificates.
Concurrently with the initial transfer of the Mortgage Loans to the Trust
pursuant to the Mortgage Loan Contribution Agreement, the Owner Trustee shall
cause the Certificates, representing 100% of the Percentage Interests of the
Trust Interest, to be executed on behalf of the Trust, authenticated and
delivered to National Mortgage Finance Corporation ("NMFC"), as the Company's
designee. No Certificate shall entitle its holder to any benefit under this
Agreement, or shall be valid for any purpose, unless there shall appear on such
Certificate a certificate of authentication substantially in the form set forth
in Exhibit A, executed by the Owner Trustee or the Owner Trustee's
authenticating agent, by manual or facsimile signature; such authentication
shall constitute conclusive evidence that such Certificate shall have been duly
authenticated and delivered hereunder. All Certificates shall be dated the date
of their authentication.

     SECTION 3.4. Registration of Transfer and Exchange of Trust Certificates.
The Certificate Registrar shall keep or cause to be kept, at the office or
agency maintained pursuant to Section 3.8, a "Certificate Register" in which,
subject to such reasonable regulations as it may prescribe, the Owner Trustee
shall provide for the registration of Certificates and of transfers and
exchanges of Certificates as herein provided. The Owner Trustee shall be the
initial "Certificate Registrar".

     Upon surrender for registration of transfer of any Certificate at the
office or agency maintained pursuant to Section 3.8, the Owner Trustee shall
execute, authenticate and deliver (or shall cause its authenticating agent to
authenticate and deliver), in the name of the designated transferee or
transferees, one or more new Certificates of a like Percentage Interest dated
the date 



                                       12
<PAGE>   17

of authentication by the Owner Trustee or any authenticating agent. At the
option of a Certificateholder, Certificates may be exchanged for other
Certificates of a like Percentage Interest upon surrender of the Certificates to
be exchanged at the office or agency maintained pursuant to Section 3.8.

     Every Certificate presented or surrendered for registration of transfer or
exchange shall be accompanied by a written instrument of transfer in form
satisfactory to the Owner Trustee and the Certificate Registrar duly executed by
the Certificateholder or his attorney duly authorized in writing. In addition,
each Certificate presented or surrendered for registration of transfer and
exchange must be accompanied by a letter from the Prospective Holder certifying
as to the representations set forth in Section 3.11(a), (b) and (c). Each
Certificate surrendered for registration of transfer or exchange shall be
canceled and disposed of by the Owner Trustee in accordance with its customary
practice.

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

     The preceding provisions of this Section notwithstanding, the Owner Trustee
shall not make and the Certificate Registrar shall not register transfers or
exchanges of Certificates for a period of 15 days preceding the Payment Date
with respect to the Certificates.

     SECTION 3.5. Mutilated, Destroyed, Lost or Stolen Certificates. If (a) any
mutilated Certificate shall be surrendered to the Certificate Registrar, or if
the Certificate Registrar shall receive evidence to its satisfaction of the
destruction, loss or theft of any Certificate and (b) there shall be delivered
to the Certificate Registrar and the Owner Trustee such security or indemnity as
may be required by them to save each of them harmless, then in the absence of
notice that such Certificate shall have been acquired by a bona fide purchaser,
the Owner Trustee on behalf of the Trust shall execute and the Owner Trustee, or
the Owner Trustee's authenticating agent, shall authenticate and deliver, in
exchange for or in lieu of any such mutilated, destroyed, lost or stolen
Certificate, a new Certificate of like Percentage Interest. In connection with
the issuance of any new Certificate under this Section, the Owner 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 connection therewith.
Any duplicate Certificate issued pursuant to this Section shall constitute
conclusive 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 3.6. Persons Deemed Owners. Each person by virtue of becoming a
Certificateholder in accordance with this Agreement shall be deemed to be bound
by the terms of this Agreement. Prior to due presentation of a Certificate for
registration of transfer, the Owner Trustee or the Certificate Registrar may
treat the Person in whose name any Certificate shall be registered in the
Certificate Register as the owner of such Certificate for the purpose of
receiving



                                       13
<PAGE>   18

distributions pursuant to Section 5.2 and for all other purposes whatsoever, and
neither the Owner Trustee nor the Certificate Registrar shall be bound by any
notice to the contrary.

     SECTION 3.7. Access to List of Holders' Names and Addresses. The Owner
Trustee shall furnish or cause to be furnished to the Servicer, the Company and
the Trust Paying Agent immediately prior to each Payment Date, a list of the
names and addresses of the Certificateholders as of the most recent Record Date.
If three or more Certificateholders or one or more Holders of Certificates,
together evidencing Percentage Interests totaling not less than 25%, apply in
writing to the Owner Trustee, and such application states that the applicants
desire to communicate with other Certificateholders with respect to their rights
under this Agreement or under the Certificates and such application is
accompanied by a copy of the communication that such applicants propose to
transmit, then the Owner Trustee shall, within five Business Days after the
receipt of such application, afford such applicants access during normal
business hours to the current list of Certificateholders. Each
Certificateholder, by receiving and holding a Certificate, shall be deemed to
have agreed not to hold any of the Company, the Certificate Registrar or the
Owner Trustee accountable by reason of the disclosure of its name and address,
regardless of the source from which such information was derived.

     SECTION 3.8. Maintenance of Office or Agency. The Owner Trustee shall
maintain an office or offices or agency or agencies where Certificates may be
surrendered for registration of transfer or exchange and where notices and
demands to or upon the Owner Trustee in respect of the Certificates and the
Basic Documents may be served. The Owner Trustee initially designates Wilmington
Trust Company as its principal corporate trust office for such purposes. The
Owner Trustee shall give prompt written notice to the Company and to the
Certificateholders of any change in the location of the Certificate Register or
any such office or agency.

     SECTION 3.9. Appointment of Trust Paying Agent. The Owner Trustee hereby
appoints Norwest Bank Minnesota, National Association, as Trust Paying Agent
under this Agreement. The Trust Paying Agent shall make distributions to
Certificateholders from the Certificate Distribution Account pursuant to Section
5.2 and shall report to the Owner Trustee on the Payment Date via facsimile
transmission of a distribution statement the amounts of such distributions to
the Certificateholders. The Trust Paying Agent shall have the revocable power to
withdraw funds from the Certificate Distribution Account for the purpose of
making the distributions referred to above. In the event that Norwest Bank
Minnesota, National Association, shall no longer be the Trust Paying Agent
hereunder, the Owner Trustee shall appoint a successor to act as Trust Paying
Agent (which shall be a bank or trust company) acceptable to the
Certificateholders. The Owner Trustee shall cause such successor Trust Paying
Agent or any additional Trust Paying Agent appointed by the Owner Trustee to
execute and deliver to the Owner Trustee an instrument in which such successor
Trust Paying Agent or additional Trust Paying Agent shall agree with the Owner
Trustee that as Trust Paying Agent, such successor Trust Paying Agent or
additional Trust Paying Agent will hold all sums, if any, held by it for payment
to the Certificateholders in trust for the benefit of the Certificateholders
entitled thereto until such sums shall be paid to such Certificateholders. After
one year from the date of receipt, the Trust Paying Agent shall promptly return
all unclaimed funds to the Owner Trustee, and 



                                       14
<PAGE>   19

upon removal of a Trust Paying Agent, such Trust Paying Agent shall also return
all funds in its possession to the Owner Trustee. The provisions of Sections
7.1, 7.3(b), 7.4, 8.1, and 10.2 as to resignations, shall apply to the Trust
Paying Agent to the same extent as if it were named therein and, to the extent
applicable, to any other paying agent appointed hereunder. Any reference in this
Agreement to the Trust Paying Agent shall include any co-paying agent unless the
context requires otherwise.

     SECTION 3.10. Restrictions on Transfer of Certificates.

         (a)   Each prospective purchaser and any subsequent transferee of a
Certificate (each, a "Prospective Holder"), other than the Company or NMFC,
shall represent and warrant, in writing, to the Owner Trustee and the
Certificate Registrar and any of their respective successors that:

         (i)   Such Person is (A) a "qualified institutional buyer" as defined
      in Rule 144A under the Securities Act of 1933, as amended (the "Securities
      Act"), and is aware that the seller of the Certificate may be relying on
      the exemption from the registration requirements of the Securities Act
      provided by Rule 144A and is acquiring such Certificate for its own
      account or for the account of one or more qualified institutional buyers
      for whom it is authorized to act, or (B) a Person involved in the
      organization or operation of the Trust or an affiliate of such Person
      within the meaning of Rule 3a-7 of the Investment Company Act of 1940, as
      amended (including, but not limited to, the Company and NMFC).

         (ii)  Such Person understands that the Certificates have not been and
      will not be registered under the Securities Act and may be offered, sold,
      pledged or otherwise transferred only to a person whom the seller
      reasonably believes is (C) a qualified institutional buyer or (D) a Person
      involved in the organization or operation of the Trust or an affiliate of
      such Person, in a transaction meeting the requirements of Rule 144A under
      the Securities Act and in accordance with any applicable securities laws
      of any state of the United States.

         (iii) Such Person understands that the Certificates bear a legend to
      the following effect:

            "THIS CERTIFICATE HAS NOT BEEN AND WILL NOT BE REGISTERED UNDER THE
            SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), OR ANY STATE
            SECURITIES LAWS. THIS CERTIFICATE MAY BE DIRECTLY OR INDIRECTLY
            OFFERED OR SOLD OR OTHERWISE DISPOSED OF (INCLUDING PLEDGED) BY THE
            HOLDER HEREOF ONLY TO (I) A "QUALIFIED INSTITUTIONAL BUYER" AS
            DEFINED IN RULE 144A UNDER THE ACT, IN A TRANSACTION THAT IS
            REGISTERED UNDER THE ACT AND APPLICABLE STATE SECURITIES LAWS OR
            THAT IS EXEMPT FROM THE REGISTRATION REQUIREMENTS OF 



                                       15
<PAGE>   20


         THE ACT PURSUANT TO RULE 144A OR (II) A PERSON INVOLVED IN THE
         ORGANIZATION OR OPERATION OF THE TRUST OR AN AFFILIATE OF SUCH A
         PERSON WITHIN THE MEANING OF RULE 3a-7 OF THE INVESTMENT COMPANY ACT
         OF 1940, AS AMENDED (INCLUDING, BUT NOT LIMITED TO, FUND AMERICA
         INVESTORS CORPORATION II) IN A TRANSACTION THAT IS REGISTERED UNDER
         THE ACT AND APPLICABLE STATE SECURITIES LAWS OR THAT IS EXEMPT FROM
         THE REGISTRATION REQUIREMENTS OF THE ACT AND SUCH LAWS. NO PERSON IS
         OBLIGATED TO REGISTER THIS CERTIFICATE UNDER THE ACT OR ANY STATE
         SECURITIES LAWS."

         (b) By its acceptance of a Certificate, each Prospective Holder agrees
and acknowledges that no legal or beneficial interest in all or any portion of
any Certificate may be transferred directly or indirectly to an entity that
holds residual securities as nominee to facilitate the clearance and settlement
of such securities through electronic book-entry changes in Accounts of
participating organizations (a "Book-Entry Nominee") and any such purported
transfer shall be void and have no effect.

         (c) No transfer of this certificate or any beneficial interest therein
shall be made to any person unless the Owner Trustee has received a certificate
from the Transferee to the effect that such transferee (i) is not a person which
is an employee benefit plan, trust or account subject to Title I of the Employee
Retirement Income Security Act of 1974, as amended ("ERISA") or Section 4975 of
the Code or a governmental plan, defined in Section 3(32) of ERISA subject to
any federal, state or local law which is, to a material extent, similar to the
foregoing provisions of ERISA or the Code (any such person being a "plan") and
(ii) is not an entity, including an insurance company separate account or
general account, whose underlying assets include plan assets by reason of a
plan's investment in the entity.

         (d) The Owner Trustee shall not execute, and shall not countersign and
deliver, a Certificate in connection with any transfer thereof unless the
transferor shall have provided to the Owner Trustee a certificate, substantially
in the form attached as Exhibit C to this Agreement, signed by the transferee,
which certificate shall contain the consent of the transferee to any amendments
of this Agreement as may be required to effectuate further the foregoing
restrictions on transfer of the Certificates to Book-Entry Nominees, and an
agreement by the transferee that it will not transfer a Certificate without
providing to the Owner Trustee a certificate substantially in the form attached
as Exhibit C to this Agreement.

         (e) The Certificates shall bear an additional legend referring to the
restrictions contained in paragraph (b) above.

Trust Agreement.

     In addition the Trust shall not commingle its assets with those of any
other entity. The Trust shall maintain its financial and accounting books and
records separate from those of any other entity. Except as expressly set forth
herein, the Trust shall pay its indebtedness, operating expenses and liabilities
from its own funds, and the Trust shall not pay the indebtedness, operating
expenses and liabilities of any other entity. The Trust shall maintain
appropriate minutes or other records of all appropriate actions and shall

and shall not take, any Bankruptcy Action with respect to the Trust or direct
the Owner Trustee to take any Bankruptcy Action with respect to the Trust.

     SECTION 4.2. Action by Holders With Respect to Bankruptcy. The Owner

<PAGE>   23

     SECTION 4.3. Restrictions on Holders' Power. The Certificateholders shall
not direct the Owner Trustee to take or refrain from taking any action if such
action or inaction would be contrary to any obligation of the Trust or the Owner
Trustee under this Agreement or any of the Basic Documents or would be contrary
to Section 2.3 nor shall the Owner Trustee be obligated to follow any such
direction, if given.

     SECTION 4.4. Majority Control. Except as expressly provided herein, any
action that may be taken by the Certificateholders under this Agreement may be
taken by the Holders of Certificates evidencing more than 50% of the Percentage
Interest in the Trust Interest and such action shall be binding upon all

the Certificateholders delivered pursuant to this Agreement shall be effective

                                   ARTICLE V
                   APPLICATION OF TRUST FUNDS; CERTAIN DUTIES

     SECTION 5.1. Establishment of Certificate Distribution Account.  The Owner
Trustee shall cause the Trust Paying Agent, for the benefit of the
Certificateholders, to establish and maintain with Norwest Bank Minnesota,
National Association, for the benefit of the Owner Trustee one or more accounts
(collectively, the "Certificate Distribution Account") that while the Trust
Paying Agent holds such account shall be entitled "Certificate Distribution
Account, Norwest Bank Minnesota, National Association, as Trust Paying Agent, in
trust for the Holders of Certificates evidencing beneficial interests in Fund
America Investors Trust 1998-NMC1." Funds shall be deposited in the Certificate
Distribution Account as required by the Indenture or, following satisfaction and
release of the Indenture, by the Servicing Agreement.

     All of the right, title and interest of the Owner Trustee in all funds on
deposit from time to time in the Certificate Distribution Account and in all
proceeds thereof shall be held for the benefit of the Certificateholders and
such other persons entitled to distributions therefrom. Except as otherwise
expressly provided herein, the Certificate Distribution Account shall be under
the sole dominion and control of the Owner Trustee for the benefit of the
Certificateholders.

     SECTION 5.2. Application of Trust Funds.

         (a) On each Payment Date, the Trust Paying Agent shall distribute to
the Certificateholders, on the basis of their respective Percentage Interests,
all amounts then on deposit in the Certificate Distribution Account.

         (b) On each Payment Date, the Trust Paying Agent shall send to
Certificateholders the statement provided to the Owner Trustee by the Indenture
Trustee pursuant to Section 2.08(d) of the Indenture with respect to such
Payment Date. If the Trust Paying Agent is an entity other than the Indenture
Trustee, the Owner Trustee shall provide a copy of such statement to the Trust
Paying Agent to enable it to perform its duties under this Section 5.2(b).



                                       19
<PAGE>   24

         (c) In the event that any withholding tax is imposed under federal,
state, or local tax on the Trust's payment (or allocations of income) to a
Certificateholder, such tax shall reduce the amount otherwise distributable to
such Certificateholder in accordance with this Section. The Owner Trustee, and
the Trust Paying Agent on its behalf, is hereby authorized and directed to
retain in the Certificate Distribution Account from amounts otherwise
distributable to the Certificateholders sufficient funds for the payment of any
tax that is legally owed by the Trust (but such authorization shall not prevent
the Owner Trustee from contesting any such tax in appropriate proceedings, and
withholding payment of such tax, if permitted by law, pending the outcome of
such proceedings). The Certificate Registrar will provide the Trust Paying Agent
with a statement indicating the amount of any such withholding tax. The amount
of any withholding tax imposed with respect to a Certificateholder shall be
treated as cash distributed to such Certificateholder at the time it is withheld
by the Trust and remitted to the appropriate taxing authority from the
Certificate Distribution Account at the direction of the Owner Trustee or the
Trust Paying Agent on its behalf. If there is a possibility that withholding tax
is payable with respect to a distribution (such as a distribution to a
Certificateholder who is a Non-U.S. Person), the Trust Paying Agent may in its
sole discretion withhold such amounts in accordance with this paragraph (c). In
the event that a Certificateholder wishes to apply for a refund of any such
withholding tax, the Owner Trustee and the Trust Paying Agent shall reasonably
cooperate with such Certificateholder in making such claim so long as such
Certificateholder agrees to reimburse the Owner Trustee for any out-of-pocket
expenses incurred.

         (d) Notwithstanding anything to the contrary herein, at any time after
the Indenture is no longer in effect but while this Agreement remains in effect,
the manager under the Management Agreement (the "Manager") shall be entitled to
a fee on each Payment Date equal to the Indenture Trustee Fee that would have
been payable to the Indenture Trustee on such Payment Date if the Indenture were
still in effect. Such fee shall be distributed to the Manager from funds in the
Certificate Distribution Account prior to distribution of any such funds to
Certificateholders. Also, in such event, the Servicer shall provide the same
information to the Manager that it would have provided to the Indenture Trustee
pursuant to the Servicing Agreement, as well as any other information concerning
the Mortgage Loans as may be reasonably requested by the Manager to enable the
Manager to perform its obligations under the Management Agreement. On each such
Payment Date, the Trust Paying Agent shall mail to each Certificateholder a
statement detailing the amount remitted to the Trust Paying Agent by the
Servicer on the related Deposit Date and setting forth the amount of the Monthly
Servicing Fee and fees paid to the Manager with respect to such Payment Date,
and the aggregate amount distributed to Certificateholders on such Payment Date.

     SECTION 5.3. Method of Payment. Distributions required to be made to
Certificateholders on any Payment Date shall be made to each Certificateholder
of record on the preceding Record Date either by wire transfer, in immediately
available funds, to the account of such Holder at a bank or other entity having
appropriate facilities therefor, if such Certificateholder shall have provided
to the Trust Paying Agent appropriate written instructions at least five
Business Days prior to such Payment Date, or, if not, by check mailed to such
Certificateholder at the address of such Holder appearing in the Certificate
Register.

<PAGE>   25

     SECTION 5.4. Segregation of Moneys; No Interest. Subject to Sections 5.1
and 5.2, moneys received by the Trust Paying Agent hereunder and deposited into
the Certificate Distribution Account will be segregated except to the extent
required otherwise by law and, if the Holders of more than 50% of the
Certificates so direct, shall be invested in Permitted Investments maturing no
later than one Business Day prior to the related Payment Date at the direction
of such Certificateholders. The Trust Paying Agent shall not be liable for
payment of any interest or losses in respect of such moneys. Investment gains
shall be for the account of and paid to the Certificateholders.

                                   ARTICLE VI
                     AUTHORITY AND DUTIES OF OWNER TRUSTEE

     SECTION 6.1. General Authority. The Owner Trustee is authorized and
directed to execute and deliver or cause to be executed and delivered the Bonds,
the Certificates and the Basic Documents to which the Trust is to be a party and
each certificate or other document attached as an exhibit to or contemplated by
the Basic Documents to which the Trust is to be a party and any amendment or
other agreement or instrument described in Article III, in each case, in such
form as the Owner Trustee shall approve, as evidenced conclusively by the Owner
Trustee's execution thereof. In addition, the Owner Trustee is authorized and
directed, on behalf of the Trust, to execute and deliver to the Authenticating
Agent the Issuer Request and the Issuer Order referred to in Section 2.11 of the
Indenture, in such form as the Company shall approve, as evidenced conclusively
by the Owner Trustee's or the Company's execution thereof, directly to the

     SECTION 6.3. Action Upon Instruction.

         (a) Subject to Article IV and in accordance with the terms of the Basic
Documents, the Certificateholders may by written instruction direct the Owner
Trustee in the management of the Trust but only to the extent consistent with
the limited purpose of the Trust. Such direction may be exercised at any time by
written instruction of the Certificateholders pursuant to Article IV. Without
limiting the generality of the foregoing, the Owner Trustee shall act as
directed by the Certificateholders in connection with Bond redemptions requested
by the Certificateholders, and shall take all actions and deliver all documents
that the Trust is required to take and deliver in accordance with Section 4.01
and Article X of the Indenture in order to effect any redemption requested by
the Certificateholders.

         (b) The Owner Trustee shall not be required to take any action
hereunder or under any Basic Document if the Owner Trustee shall have reasonably
determined, or shall have been advised by counsel, that such action is likely to
result in liability on the part of the Owner Trustee or is contrary to the terms
hereof or of any Basic Document or is otherwise contrary to law.

         (c) Whenever the Owner Trustee is unable to decide between alternative
courses of action permitted or required by the terms of this Agreement or under
any Basic Document, the Owner Trustee shall promptly give notice (in such form
as shall be appropriate under the circumstances) to the Certificateholders
requesting instruction from the Certificateholders as to the course of action to
be adopted, and to the extent the Owner Trustee acts in good faith in accordance
with any written instruction of the Certificateholders received, the Owner
Trustee shall not be liable on Account of such action to any Person. If the
Owner Trustee shall not have received appropriate instruction within 10 days of
such notice (or within such shorter period of time as reasonably may be
specified in such notice or may be necessary under the circumstances) it may,
but shall be under no duty to, take or refrain from taking such action, not
inconsistent with this Agreement or the Basic Documents, as it shall deem to be
in the best interests of the Certificateholders, and shall have no liability to
any Person for such action or inaction.

         (d) In the event that the Owner Trustee is unsure as to the application
of any provision of this Agreement or any Basic Document or any such provision
is ambiguous as to its application, or is, or appears to be, in conflict with
any other applicable provision, or in the event that this Agreement permits any
determination by the Owner Trustee or is silent or is incomplete as to the
course of action that the Owner Trustee is required to take with respect to a
particular set of facts, the Owner Trustee may give notice (in such form as
shall be appropriate under the circumstances) to the Certificateholders
requesting instruction and, to the extent that the Owner Trustee acts or
refrains from acting in good faith in accordance with any such instruction
received, the Owner Trustee shall not be liable, on account of such action or
inaction, to any Person. If the Owner Trustee shall not have received
appropriate instruction within 10 days of such notice (or within such shorter
period of time as reasonably may be specified in such notice or may be necessary
under the circumstances) it may, but shall be under no duty to, take or refrain
from taking such action, not inconsistent with this Agreement or the Basic
Documents, as 


                                       22
<PAGE>   27
it shall deem to be in the best interests of the Certificateholders, and shall
have no liability to any Person for such action or inaction.

     SECTION 6.4. No Duties Except as Specified in This Agreement, The Basic
Documents or Any Instructions. The Owner Trustee shall not have any duty or
obligation to manage, make any payment with respect to, register, record, sell,
dispose of, or otherwise deal with the Owner Trust Estate, or to otherwise take
or refrain from taking any action under, or in connection with, any document
contemplated hereby to which the Owner Trustee is a party, except as expressly
provided by the terms of this Agreement, any Basic Document or in any document
or written instruction received by the Owner Trustee pursuant to Section 6.3;
and no implied duties or obligations shall be read into this Agreement or any
Basic Document against the Owner Trustee. The Owner 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 or to prepare or file any
Securities and Exchange Commission filing for the Trust or to record this
Agreement or any Basic Document. The Owner Trustee nevertheless agrees that it
will, at its own cost and expense, promptly take all action as may be necessary
to discharge any liens on any part of the Owner Trust Estate that result from
actions by, or claims against, the Owner Trustee that are not related to the
ownership or the administration of the Owner Trust Estate.

     SECTION 6.5. No Action Except Under Specified Documents or Instructions.
The Owner Trustee shall not manage, control, use, sell, dispose of or otherwise
deal with any part of the Owner Trust Estate except (i) in accordance with the
powers granted to and the authority conferred upon the Owner Trustee pursuant to
this Agreement, (ii) in accordance with the Basic Documents and (iii) in
accordance with any document or instruction delivered to the Owner Trustee
pursuant to Section 6.3.

     SECTION 6.6. Restrictions. The Owner Trustee shall not take any action (a)
that is inconsistent with the purposes of the Trust set forth in Section 2.3 or
(b) that, to the actual knowledge of the Owner Trustee, would result in the
Trust's becoming taxable as a corporation for Federal income tax purposes. The
Certificateholders shall not direct the Owner Trustee to take action that would
violate the provisions of this Section.

     SECTION 10.2. Resignation or Removal of Owner Trustee. The Owner Trustee
may at any time resign and be discharged from the trusts hereby created by

competent jurisdiction for the appointment of a successor Owner Trustee.

     If at any time the Owner Trustee shall cease to be eligible in accordance
with the provisions of Section 10.1 and shall fail to resign after written
request therefor by the Certificateholders or the Servicer, or if at any time
the Owner Trustee shall be legally unable to act, or shall be adjudged bankrupt

successor Owner Trustee pursuant to any of the provisions of this Section shall
not become effective until acceptance of appointment by the successor Owner
Trustee pursuant to Section 10.3 and payment of all fees and expenses owed to

and such successor Owner Trustee without any further act, deed or conveyance,
shall become fully vested with all the rights, powers, duties, and obligations
of its predecessor under this Agreement, with like effect as if originally named
as Owner Trustee. The predecessor Owner Trustee shall upon payment of its fees
and expenses deliver to the successor Owner Trustee all documents and statements
and moneys held by it under this Agreement; and the Company and the predecessor
Owner Trustee shall execute and deliver such instruments and do such other
things as may reasonably be required for fully and certainly vesting and
confirming in the successor Owner Trustee all such rights, powers, duties, and
obligations.

Trustee to all Certificateholders, the Indenture Trustee, the Trust Paying
Agent, the Bondholders and the Rating Agencies. If the Company fails to mail
such notice within 10 days after acceptance of appointment by the successor
Owner Trustee, the successor Owner Trustee shall cause such notice to be mailed
at the expense of the Company.

     SECTION 10.4. Merger or Consolidation of Owner Trustee. Any corporation
into which the Owner Trustee may be merged or converted or with which it may be
consolidated or any corporation resulting from any merger, conversion or
consolidation to which the Owner Trustee shall be a party, or any corporation
succeeding to all or substantially all of the corporate trust business of the
Owner Trustee, shall be the successor of the Owner Trustee hereunder, provided
such corporation shall be eligible pursuant to Section 10.1, without the
execution or filing of any instrument or any further act on the part of any of
the parties hereto, anything herein to the contrary notwithstanding; provided
further that the Owner Trustee shall mail notice of such merger or consolidation
to the Rating Agencies.

     SECTION 10.5. 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 Owner Trust Estate or any Mortgaged Property may at the time be
located, and for the purpose of performing certain duties and obligations of the
Owner Trustee with respect to the Trust and the Certificates, the Owner Trustee
shall have the power and shall execute and deliver all instruments to appoint
one or more Persons approved by the Owner Trustee to act as co-trustee, jointly
with the Owner Trustee, or separate trustee or separate trustees, of all or any
part of the Owner Trust Estate, and to vest in such Person, in such capacity,
such title to the Trust, or any part thereof, and, subject to the other
provisions of this Section, such powers, duties, obligations, rights and trusts
as the Owner Trustee may consider necessary or desirable. No co-trustee or
separate trustee under this Agreement shall be required to meet the terms of
eligibility as a successor trustee pursuant to Section 10.1 and no notice of the
appointment of any co-trustee or separate trustee shall be required pursuant to
Section 10.3.

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

           (i) all rights, powers, duties and obligations conferred or imposed
      upon the Owner Trustee shall be conferred upon and exercised or performed
      by the Owner 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 Owner 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, the Owner Trustee shall be
      incompetent or 


                                       31
<PAGE>   36

     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 Owner Trustee;

           (ii)  no trustee under this Agreement shall be personally liable by
     reason of any act or omission of any other trustee under this Agreement;
     and

           (iii) the Owner Trustee may at any time accept the resignation of or
     remove any separate trustee or co-trustee.

     Any notice, request or other writing given to the Owner Trustee shall be
deemed to have been given to the separate trustees and co-trustees, as if given
to each of them. Every instrument appointing any separate trustee or co-trustee,
other than this Agreement, shall refer to this Agreement and to the conditions
of this Article. Each separate trustee and co-trustee, upon its acceptance of
appointment, shall be vested with the estates specified in its instrument of
appointment, either jointly with the Owner 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 Owner Trustee. Each
such instrument shall be filed with the Owner Trustee.

     Any separate trustee or co-trustee may at any time appoint the Owner
Trustee as 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
Owner Trustee, to the extent permitted by law, without the appointment of a new
or successor trustee.

                                   ARTICLE XI
                                 MISCELLANEOUS

     SECTION 11.1. Supplements and Amendments. This Agreement may be amended by
the Company, and the Owner Trustee, with prior written notice to the Rating
Agencies, but without the consent of any of the Bondholders or the
Certificateholders or the Indenture Trustee, to cure any ambiguity, to correct
or supplement any provisions in this Agreement or for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions in
this Agreement or of modifying in any manner the rights of the Bondholders or
the Certificateholders; provided, however, such action shall not adversely
affect in any material respect the interests of any Bondholder or
Certificateholder. An amendment described above shall be deemed not to adversely
affect in any material respect the interests of any Bondholder or
Certificateholder if the party requesting the amendment satisfies the Rating
Agency Condition with respect to such amendment.

     This Agreement may also be amended from time to time by the Company and the
Owner Trustee, with the prior written consent of the Rating Agencies and with
the prior written consent of the Indenture Trustee, the Holders (as defined in
the Indenture) of Bonds evidencing more 


                                       32
<PAGE>   37

than 50% of the Outstanding Amount of the Bonds, the Holders of Certificates
evidencing more than 50% of the Percentage Interests of the Trust Interest and
if the party requesting such amendment satisfies the Rating Agency Condition
with respect to such amendment, 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 Bondholders or the
Certificateholders; provided, however, no such amendment shall (a) increase or
reduce in any manner the amount of, or accelerate or delay the timing of,
collections of payments on the Mortgage Loans or distributions that shall be
required to be made for the benefit of the Bondholders or the
Certificateholders, (b) reduce the aforesaid percentage of the Outstanding
Amount of the Bonds or the Percentage Interests required to consent to any such
amendment, in either case of clause (a) or (b) without the consent of the
holders of all the outstanding Bonds, and in the case of clause (b) without the
consent of the Holders of all the outstanding Certificates.

     Promptly after the execution of any such amendment or consent, the Owner
Trustee shall furnish written notification of the substance of such amendment or
consent to each Certificateholder, the Indenture Trustee and each of the Rating
Agencies.

     It shall not be necessary for the consent of Certificateholders, the
Bondholders or the Indenture Trustee pursuant to this Section to approve the
particular form of any proposed amendment or consent, but it shall be sufficient
if such consent shall approve the substance thereof. The manner of obtaining
such consents (and any other consents of Certificateholders provided for in this
Agreement or in any other Basic Document) and of evidencing the authorization of
the execution thereof by Certificateholders shall be subject to such reasonable
requirements as the Owner Trustee may prescribe.

     Promptly after the execution of any amendment to the Certificate of Trust,
the Owner Trustee shall cause the filing of such amendment with the Secretary of
State.

     Prior to the execution of any amendment to this Agreement or the
Certificate of Trust, the Owner Trustee shall be entitled to receive and rely
upon an Opinion of Counsel stating that the execution of such amendment is
authorized or permitted by this Agreement. The Owner Trustee may, but shall not
be obligated to, enter into any such amendment which affects the Owner Trustee's
own rights, duties or immunities under this Agreement or otherwise.

     SECTION 11.2. No Legal Title to Owner Trust Estate in Holders. The
Certificateholders shall not have legal title to any part of the Owner Trust
Estate. The Certificateholders shall be entitled to receive distributions with
respect to their undivided ownership interest therein only in accordance with
Articles V and IX. No transfer, by operation of law or otherwise, of any right,
title, or interest of the Certificateholders to and in their ownership interest
in the Owner Trust Estate shall operate to terminate this Agreement or the
trusts hereunder or entitle any transferee to an Accounting or to the transfer
to it of legal title to any part of the Owner Trust Estate.

     SECTION 11.3. Limitations on Rights of Others. Except for Section 2.7, the
provisions of this Agreement are solely for the benefit of the Owner Trustee,
the Company, the Certificateholders and, to the extent expressly provided
herein, the Indenture Trustee and the 


                                       33

respect of this Agreement or any covenants, conditions or provisions contained
herein.

prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

parties hereto in separate counterparts, each of which when so executed and
delivered shall be an original, but all such counterparts shall together

                                   ARTICLE II
                 ADMINISTRATION AND SERVICING OF MORTGAGE LOANS

         SECTION 2.01. Servicing Generally.

                 (a) General Duties; Licensing. Acting directly or through one
or more Sub-Servicers as provided in Section 2.14, the Servicer, as servicer,
shall administer the Mortgage Loans with reasonable care, using that degree of
skill and attention that the Servicer exercises with respect to all comparable
mortgage loans that it services for itself or others. The Servicer shall follow
its customary standards, policies and procedures in performing its duties as
Servicer, to the extent not in conflict with the provisions of this Agreement.
Notwithstanding the appointment of any Sub-Servicer, the Servicer shall remain
liable for the performance of all of the servicing obligations and
responsibilities under this Agreement. The Servicer shall maintain all licenses
and qualifications necessary under the laws of any jurisdiction where Mortgaged
Properties are located for it to perform the servicing obligations hereunder
legally. The Servicer shall cause any Sub-Servicer to maintain for it all
licenses and qualifications necessary to perform its servicing obligations in
the states where the Mortgaged Properties to which the applicable Sub-Servicing
Agreement relates are located. The Servicer shall cooperate with the Issuer and
the Indenture Trustee and furnish to the Issuer and the Indenture Trustee such
information in its possession as may be necessary or otherwise reasonably
requested to enable the Issuer and the Indenture Trustee to perform their
respective tax reporting duties under the Indenture. The Issuer and the
Indenture Trustee shall 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.

                 (b) Interest Rate and Monthly Payment Adjustments. The Servicer
shall enforce each Mortgage Loan and shall timely calculate, record, report and
apply all Mortgage Interest Rate adjustments in accordance with the related
Mortgage Note. The Servicer's records shall, at all times, reflect the
then-current Mortgage Interest Rate and Monthly Payment and the Servicer shall
timely notify the Mortgagor of any changes to the Mortgage Interest Rate and the
Monthly Payment.

                 (c) Servicer Authority. Without limiting the generality of the
foregoing, the Servicer (1) shall continue, and is hereby authorized and
empowered by the Issuer and the Indenture Trustee, to execute and deliver, on
behalf of itself, the Issuer, the Bondholders and the Indenture 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 related Mortgaged Properties and
(2) subject to Section 2.05, to institute foreclosure proceedings or obtain
deeds in lieu of foreclosure so as to convert ownership of Mortgaged Properties
into the name of the Indenture Trustee pursuant to Section 2.05 of this
Agreement. The Servicer may sue to enforce or collect on any of the Mortgage
Loans or any insurance policy covering a Mortgage Loan, in its own name if
possible, or on behalf of the Issuer or the Indenture Trustee. If the Servicer
commences a legal proceeding to enforce a Mortgage Loan or any such insurance
policy, the Issuer and the Indenture Trustee shall 


                                       15
<PAGE>   20

thereupon be deemed to have automatically assigned the Mortgage Loan or the
rights under such insurance policy to the Servicer for purposes of collection
only. If, however, in any suit or legal proceeding for enforcement, it is held
that the Servicer may not enforce or collect on a Mortgage Loan or any insurance
policy covering a Mortgage Loan on the ground that it is not a real party in
interest or a holder entitled to enforce such Mortgage Loan or such insurance
policy, as the case may be, then the Issuer and the Indenture Trustee shall,
upon the written request of a Servicing Officer, execute and return to the
Servicer such powers of attorney and other documents as are necessary or
appropriate to enable the Servicer to enforce such Mortgage Loan or insurance
policy, as the case may be, and which are prepared by the Servicer and submitted
to the Issuer or the Indenture Trustee for execution.

         The Servicer, on behalf of the Issuer and the Bondholders, shall
prepare, execute, deliver and take all actions reasonably necessary to protect
the Trust Estate pursuant to Section 3.05 of the Indenture and shall, on behalf
of the Issuer, execute and deliver and take any additional actions as shall be
deemed necessary to effect the administrative obligations of the Issuer under
the Indenture.

                 (d) Independent Contractor Relationship. The relationship of
the Servicer to the Issuer and the Indenture Trustee under this Agreement is
intended by the parties to be that of an independent contractor and not that of
a joint venturer, partner or agent.

         SECTION 2.02. Collection of Certain Mortgage Loan Payments; Collection
Account.

                 (a) Collection Procedures. The Servicer shall, to the extent
such procedures shall be consistent with this Agreement, follow such collection
procedures as it follows from time to time with respect to mortgage loans in its
servicing portfolio that are comparable to the Mortgage Loans. A summary of the
Servicer's collection procedures as of the Closing Date is attached hereto as
Exhibit D. Consistent with the foregoing, the Servicer may in its discretion (1)
waive any assumption fees, late payment charges, charges for checks returned for
insufficient funds, prepayment charges (other than prepayment premiums and
penalties), if any, or other fees that may be collected in the ordinary course
of servicing the Mortgage Loans, (2) if a Mortgagor is in default or appears
about to be in default because of a Mortgagor's financial condition, arrange
with the Mortgagor a schedule for the payment of delinquent payments due on the
related Mortgage Loan or (3) modify payments of monthly principal and interest
on any Mortgage Loan becoming subject to the terms of the Soldiers' and Sailors'
Civil Relief Act of 1940, as amended (the "Relief Act"), in accordance with the
Servicer's general policies for comparable mortgage loans subject to the Relief
Act. Notwithstanding the foregoing, in the event that any Mortgage Loan is in
default or, in the judgment of the Servicer, such default is reasonably
foreseeable, the Servicer, consistent with the servicing standard set forth in
Section 2.01, may waive, modify or vary any term of such Mortgage Loan
(including modifications that change the Mortgage Interest Rate, forgive the
payment of principal or interest or extend the final maturity date of such
Mortgage Loan), accept payment from the related Mortgagor of an amount less than
the unpaid principal balance in final satisfaction of such Mortgage Loan, or
consent to the postponement of such compliance with any such term or otherwise
grant indulgence to any Mortgagor if in the 


                                       16
<PAGE>   21

Servicer's determination such waiver, modification, postponement or indulgence
will maximize the recovery with respect to such Mortgage Loan. In no event,
however, may the Servicer waive prepayments premiums or penalties, if any. The
Servicer will not consent to the placement of a deed of trust or mortgage, as
applicable, on any Mortgaged Property that has a priority equal to or higher
than the lien securing the related Mortgage Loan unless such Mortgage Loan is
prepaid in full. No partial release of a Mortgage Loan shall be made if it would
cause the Loan-to-Value Ratio of the Mortgage Loan (taking into account the
partial release) to be higher than the Loan-to-Value Ratio of the Mortgage Loan
at origination.

                 (b) Collection Account. The Servicer shall establish and
maintain, or cause to be established and maintained, one or more Eligible
Accounts that in the aggregate are the Collection Account. At the Servicer's
option, amounts held in the Collection Account shall be invested by the
depository institution or trust company then maintaining the account at the
written direction of the Servicer in Permitted Investments that mature not later
than the Deposit Date next succeeding the date of investment. The Servicer shall
not retain any cash or investment in the Collection Account for a period in
excess of 12 months and cash therein shall be considered transferred on a
first-in, first-out basis to the Indenture Trustee for inclusion in the Bond
Account, as described in Section 2.02(d). All net income and gain realized from
any such investment shall be for the benefit of the Servicer as additional
servicing compensation and shall be subject to its withdrawal or order from time
to time. Any losses realized in connection with any such investment shall be for
the account of the Servicer and the Servicer shall deposit or cause to be
deposited the amount of such loss (to the extent not offset by income from other
investments) in the Collection Account immediately upon the realization of such
loss and shall have no right to reimbursement therefor. Any benefit resulting
from deposits, maintenance or investment of funds in the Collection Account
shall be for the Servicer's benefit.

                 (c) Deposits to Collection Account. Subject to the last
paragraph of this Section 2.02(c), the Servicer shall deposit in the Collection
Account each of the following payments on and collections in respect of the
Mortgage Loans as soon as practicable, but in no event later than the close of
business on the second Business Day after its receipt thereof:

                 (i)   all payments in respect of or allocable to interest on 
         the Mortgage Loans (including any net income from REO Properties), net
         of the Monthly Servicing Fees attributable to such payments;

                 (ii)  all collections of principal on or with respect to the
         Mortgage Loans;

                 (iii) all Payments Ahead;

                 (iv)  all Net Liquidation Proceeds;

                 (v)   all Trust Insurance Proceeds (including, for this
         purpose, any amounts required to be credited by the Servicer pursuant
         to the last sentence of Section 2.03); and



                                       17
<PAGE>   22

                 (vi)  all prepayment premiums or penalties received with
         respect to the Mortgage Loans;

in any case net of its Monthly Servicing Fees, Ancillary Servicing Compensation,
and reimbursable outstanding Servicing Advances and Monthly Advances, to the
extent the Servicer's automated system deducts such amounts from collected funds
prior to deposit of such collected funds into the Collection Account.

         The Servicer shall replace all amounts previously withdrawn from the
Collection Account and applied by the Servicer towards the payment of a Monthly
Advance pursuant to Section 4.01(a) or towards the payment of a Servicing
Advance pursuant to Section 4.01(b) by depositing into the Collection Account on
or prior to the Deposit Date immediately following such withdrawal an amount
equal to the total of all such amounts so applied since the immediately
preceding Deposit Date.

         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 fees, late payment charges, charges for checks returned for
insufficient funds, prepayment charges (other than prepayment premiums and
penalties), if any, or extension or other administrative charges paid by
Mortgagors or amounts received by the Servicer for the account of Mortgagors for
application towards the payment of taxes, insurance premiums, assessments and
similar items. The amounts deposited in the Collection Account are subject to
withdrawal by the Servicer, from time to time, (1) to make transfers to the
Indenture Trustee for deposit into the Bond Account pursuant to Section 2.02(d),
(2) to pay itself the Monthly Servicing Fee, to the extent not already paid to
or retained by the Servicer, pursuant to Section 2.07, Ancillary Servicing
Compensation, and investment income on Permitted Investments, (3) to make
Servicing Advances or to reimburse itself for Servicing Advances, as applicable,
in either case in accordance with Section 4.01(b), (4) to make Monthly Advances
in accordance with Section 4.01(a) or to reimburse itself for payments of
Monthly Advances as described in Section 4.01(a), and (5) to clear and terminate
the Collection Account. In addition, if the Servicer deposits in the Collection
Account any amount not required to be so deposited or any amount in respect of
payments by Mortgagors made by checks subsequently returned for insufficient
funds or other reason for non-payment, it may at any time withdraw such amount
from the Collection Account, any provision herein to the contrary
notwithstanding.

         Upon such terms as the Rating Agencies may approve, the Servicer may
make the deposits to the Collection Account referred to in Section 2.02(c) on a
later day than the second Business Day after receipt of the amounts required to
be so deposited, which terms and later day shall be specified by the Rating
Agencies and confirmed to the Indenture Trustee and the Servicer in writing;
provided, however, that in any event such amounts shall be deposited into the
Collection Account no later than the next succeeding Deposit Date.

                 (d) Remittances to Indenture Trustee. At or before 12:00 noon
Denver time on each Deposit Date, the Servicer shall withdraw from the
Collection Account all amounts on 


                                       18
<PAGE>   23

deposit therein that constitute any portion of Remittable Funds for the related
Deposit Date (including any amounts therein that are being held for remittance
on a subsequent Deposit Date and are applied toward the Monthly Advance for the
related Deposit Date pursuant to Section 4.01(a)) and remit such amounts to the
Indenture Trustee for deposit into the Bond Account. In addition, any amounts
required pursuant to the Indenture to be deposited into the Bond Account in
connection with a purchase of any Mortgage Loans by the Servicer pursuant to the
Indenture and any other amounts (including Monthly Advances and Compensating
Interest for such Deposit Date) required by this Agreement to be deposited by
the Servicer with the Indenture Trustee shall be remitted to the Indenture
Trustee for deposit into the Bond Account on the applicable Deposit Date. On
each Deposit Date after the Indenture has been satisfied and released for so
long as the Deposit Trust Agreement remains in effect, the Servicer shall remit
all Remittable Funds to the Trust Paying Agent, for deposit into the Certificate
Distribution Account in accordance with the Deposit Trust Agreement.

         In the event that the Servicer does not remit all Remittable Funds for
the related Payment Date on the Deposit Date, the Servicer also shall pay to the
Indenture Trustee on demand, for its own account and not for the account of the
Bondholders, an amount equal to the income that the Indenture Trustee would have
received on the investment of such funds in Permitted Investments, as reasonably
calculated by the Indenture Trustee, from the Deposit Date until the date that
such Remittable Funds have been remitted to the Indenture Trustee.

         SECTION 2.03. Hazard Insurance Policies.

         The Servicer shall cause to be maintained for each Mortgage Loan
(including any Mortgage Loan as to which the related Mortgaged Property has been
acquired on behalf of the Indenture Trustee upon foreclosure, by deed in lieu of
foreclosure or comparable conversion), hazard insurance (including flood
insurance coverage, if obtainable, to the extent such property is located in a
federally designated flood area in such amount as is required under applicable
FEMA guidelines) with extended coverage in an amount that is not less than the
lesser of (1) the maximum insurable value from time to time of the improvements
that are a part of such property or a replacement cost basis, or (2) the
principal balance of such Mortgage Loan, determined in the case of a Mortgage
Loan that has been foreclosed at the time of such foreclosure; provided,
further, that such hazard insurance shall be in an amount not less than such
amount as is necessary to avoid the application of any coinsurance clause
contained in the related hazard insurance policy. Each such hazard insurance
policy shall contain a standard mortgagee loss payable clause naming the
originator, its successors and assigns, as mortgagee. The Servicer shall be
under no obligation to require that any Mortgagor maintain earthquake or other
additional insurance and shall be under no obligation itself to maintain any
such additional insurance on property acquired in respect of a Mortgage Loan,
other than pursuant to such applicable laws and regulations as shall at any time
be in force and as shall require such additional insurance. Amounts collected by
the Servicer under any such policies shall be deposited into the Collection
Account in accordance with Section 2.02 to the extent that they constitute Net
Liquidation Proceeds or Trust Insurance Proceeds. If the Servicer shall obtain
and maintain a blanket policy, issued by an insurer acceptable to each Rating
Agency, insuring 


                                       19

against such hazard losses, it shall conclusively be deemed to have satisfied
its obligations as set forth in the first sentence of this Section, it being
understood and agreed that such policy may contain a deductible clause that is
in form and substance consistent with standard industry practice, 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 the first sentence of
this Section 2.03, and there shall have been a loss that would have been covered
by such policy, deposit in the Collection Account in accordance with Section
2.02 the amount not otherwise payable under the blanket policy because of such
deductible clause from its own funds, and such amount shall not be reimbursable
to the Servicer.

         SECTION 2.04. Enforcement of Due-on-Sale Clauses; Assumption and
                       Modification Agreements.

         In any case in which property subject to a Mortgage is voluntarily
conveyed by the Mortgagor, the Servicer may enter into an assumption agreement
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 related
Mortgage Note and, to the extent permitted by applicable law or the related
mortgage documents, the Mortgagor remains liable thereon. If the Person to whom
such Mortgaged Property has been or is about to be conveyed satisfies the
Servicer's then-current underwriting standards as to borrower creditworthiness
for mortgage loans similar to the Mortgage Loans and is in the same Seller
credit rating category as that which was assigned to the borrower under the
Mortgage Loan being replaced, the Servicer may enter into a substitution of
liability agreement with such person, under which the previous Mortgagor is
released from liability thereon and the transferee is substituted as a Mortgagor
and becomes liable under the Mortgage Note. The Servicer shall not permit an
assumption agreement or a substitution of liability agreement with respect to a
Mortgage Loan unless permitted by applicable law and unless the Servicer
determines that such action would not materially increase the risk of default or
delinquency on such Mortgage Loan or materially impair the security for such
Mortgage Loan. The Servicer will not enter into any assumption agreement or
substitution of liability agreement unless such agreement complies with the
Servicer's standard servicing procedures and the Servicer would enter into such
agreement with respect to a mortgage loan in its own portfolio. The Servicer
shall notify the Indenture Trustee that any assumption agreement or substitution
of liability agreement has been completed and the Servicer shall forward to the
Indenture Trustee the original of such assumption agreement or substitution of
liability agreement. Such assumption agreement or substitution of liability
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. In connection with any such agreement, the Mortgage Interest Rate
shall not be reduced (but may be increased), the Principal Balance of such
Mortgage Loan shall not be changed and the term of such Mortgage Loan will not
be extended beyond the existing term of such Mortgage Loan. Any fee collected by
the Servicer for entering into any such agreement shall be retained by the
Servicer as Ancillary Servicing Compensation.



                                       20
<PAGE>   25

         In the event the Servicer does not approve an assumption of a Mortgage
Loan as described above, the Servicer will enforce any related due-on-sale
clause to the extent permitted by the related Mortgage Note and Mortgage and by
all applicable laws and regulations, but only to the extent the Servicer does
not believe that such enforcement will (1) adversely affect or jeopardize
coverage under any related insurance policy, (2) result in legal action by the
Mortgagor, or (3) materially increase the risk of default or delinquency on, or
materially impair the security for, such Mortgage Loan.

         Notwithstanding the foregoing paragraph of this Section 2.04 or any
other provision of this Agreement, the Servicer shall not be deemed to be in
default, breach or any other violation of its obligations hereunder by reasons
of any assumption of a Mortgage Loan, or transfer of any Mortgaged Property
without the assumption thereof, by operation of law or any assumption or
transfer that the Servicer reasonably believes it may be restricted by law from
preventing, for any reason whatsoever.

         SECTION 2.05. Realization upon Defaulted Mortgage Loans; Options to
                       Purchase Mortgage Loans.

         The Servicer, on behalf of and as the agent of the Indenture Trustee,
shall foreclose upon or otherwise comparably convert the ownership of Mortgaged
Properties securing such of the Mortgage Loans as come into and continue in
default and as to which no satisfactory arrangements can be made for collection
of delinquent payments pursuant to Section 2.02(a) into the name of the
Indenture Trustee; provided, however, that if the Servicer has actual knowledge
or reasonably believes that any Mortgaged Property is affected by hazardous or
toxic wastes or substances, then the Servicer will cause to be undertaken an
environmental inspection of the Mortgaged Property that complies with Fannie
Mae's selling and servicing guide applicable to single family homes and its
servicing procedures. If the environmental inspection reveals any potentially
hazardous substances, the Servicer will notify the Indenture Trustee, and the
Servicer will not foreclose or accept a deed in lieu of foreclosure on the
Mortgaged Property without the consent of the Indenture Trustee. In connection
with such 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 first lien one- to four-family mortgage loan
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 Mortgaged Property unless, in the reasonable judgment of
the Servicer, such foreclosure, correction or restoration will increase Net
Liquidation Proceeds (taking into account the reimbursement of such expenses to
the Servicer and any unreimbursed Servicing Advances and Monthly Advances made
or expected to be made with respect to such Mortgage Loan).

         To the extent the Net Liquidation Proceeds derived from any such
foreclosure or conversion exceed the Principal Balance of the related Mortgage
Loan and accrued interest thereon at the applicable Mortgage Interest Rate
through the Determination Date during the Collection Period in which such
foreclosure or conversion occurs (net of any Monthly Advances or Servicing
Advances made by the Servicer with respect to such Mortgage Loan and that were


                                       21
<PAGE>   26

unreimbursed prior to the receipt of such Net Liquidation Proceeds), such excess
shall be paid directly to the Servicer as additional Servicing Compensation and
shall be free from the lien of the Indenture.

         The Servicer must determine, as to each defaulted Mortgage Loan, when
such Mortgage Loan has become a Liquidated Mortgage Loan.

         The Servicer, at its sole option, may purchase from the Trust Estate on
any Deposit Date any Mortgage Loan as to which the related Mortgagor has failed
to make full Monthly Payments as required under the related Mortgage Note for
three consecutive months at any time following the Cut-off Date and prior to
such Deposit Date at a price equal to the Purchase Price by transferring such
amount to the Indenture Trustee for deposit into the Bond Account on such
Deposit Date pursuant to Section 2.02; provided, however, that the aggregate
Principal Balances of the Mortgage Loans purchased by the Servicer pursuant to
the exercise of the option granted in this sentence shall not exceed 10% of the
Initial Pool Balance. Upon the receipt by the Indenture Trustee of the Purchase
Price for any Mortgage Loan as to which the Servicer has exercised its option to
purchase pursuant to this paragraph, the Indenture Trustee shall release to the
Servicer the Mortgage File pertaining to each such Mortgage Loan and the
Indenture Trustee and the Issuer shall execute and deliver such instruments of
transfer and all other documents furnished by the Servicer as are necessary to
transfer their respective interests in such Mortgage Loans to the Servicer. For
purposes of this Agreement, any purchase effected in accordance with this
paragraph shall be deemed to be a prepayment of each Mortgage Loan so purchased.
The Servicer also shall have certain rights to redeem the Bonds pursuant to
Section 10.01 of the Indenture.

         In the event that title to any Mortgaged Property is acquired as REO
Property by the Indenture Trustee in foreclosure or by deed in lieu of
foreclosure, the deed or certificate of sale shall be issued to the Indenture
Trustee, or to its nominee, on behalf of the Bondholders, and the Servicer shall
manage, conserve, protect and operate each such REO Property for the Bondholders
solely for the purpose of its prompt disposition and sale. The Servicer shall
use its best efforts to dispose of each such REO Property as expeditiously as
possible consistent with the goal of maximizing Net Liquidation Proceeds (taking
into account any unreimbursed Servicing Advances and Monthly Advances made or
expected to be made with respect to such REO Property). None of the Issuer, the
Indenture Trustee or the Servicer, acting on behalf of the Trust Estate, shall
provide financing from the Trust Estate to any purchaser of any such REO
Property.

         SECTION 2.06. Indenture Trustee to Cooperate; Release of Mortgage
                       Files.

                 (a) Upon the payment in full of the principal balance of any
Mortgage Loan, the Servicer shall notify the Indenture Trustee by a
certification in the form of Exhibit B hereto (a "Request for Release") (which
certification shall include a statement to the effect that all amounts received
in connection with such payment which are required to be deposited to the
Collection Account pursuant to Section 2.02 have been so deposited) of a
Servicing Officer. Such notification shall be made each month at the time that
the Servicer delivers its Servicer Remittance Report to the Issuer and the
Indenture Trustee pursuant to Section 3.01. Upon any 


                                       22
<PAGE>   27

such payment in full, the Servicer is authorized to procure a deed of full
reconveyance covering the related Mortgaged Property encumbered by such
Mortgage, which deed, except as otherwise provided in applicable law, shall be
recorded in the office of the County Recorder in which the Mortgage is recorded,
or, as the case may be, to procure an instrument of satisfaction or, if the
related Mortgagor so requests, an assignment without recourse, in each case
prepared by the Servicer at its expense and executed by the Indenture Trustee,
which deed of reconveyance, instrument of satisfaction or assignment shall be
delivered by the Servicer to the Person entitled thereto, it being understood
and agreed that no expenses incurred in connection with such deed of
reconveyance, assignment or instrument of satisfaction shall be reimbursed from
amounts at the time on deposit in the Collection Account.

                 (b) From time to time and as appropriate for the servicing or
foreclosure of any Mortgage Loan or to effect a partial release of any Mortgaged
Property from the lien of the related Mortgage, the Servicer shall deliver to
the Indenture Trustee a Request for Release requesting the related Trustee
Mortgagee Loan File. The Indenture Trustee shall, within five Business Days
after its receipt of such Request for Release, release the related Mortgage File
to the Servicer. Any such Request for Release shall obligate the Servicer to
return the Mortgage File to the Trustee by the twenty-first day following the
release thereof, unless (1) the Mortgage Loan has been liquidated and the Net
Liquidation Proceeds relating to the Mortgage Loan have been deposited in the
Collection Account or the Bond Account or (2) the Mortgage File or such document
has been delivered to an attorney, or to a public trustee or other public
official as required by law, for the purposes of initiating or pursuing legal
action or other proceedings for the foreclosure of the Mortgaged Property either
judicially or non-judicially, and the Servicer has delivered to the Indenture
Trustee a certificate of the Servicer certifying as to the name and address of
the Person to which such Mortgage File or such document was delivered and the
purpose or purposes of such delivery.

                 (c) Upon receipt of an officer's certificate of the Servicer
stating that such Mortgage Loan was liquidated and that all amounts received or
to be received in connection with such liquidation which are required to be
deposited into the Collection Account or the Bond Account have been so
deposited, or that such Mortgage Loan has become an REO Property (each, a
"Servicing Officer's Certificate"), the Indenture Trustee shall execute any
documents prepared by the Servicer and delivered to it as necessary or
appropriate to enable the Servicer to perform its obligations hereunder,
including, without limitation, documents to enable the Servicer to convey title
to a Mortgaged Property to the Mortgagor or its designee upon payment of the
Mortgage Loan in full or to convey title to an REO Property to the purchaser
thereof, or to convey title to a Mortgaged Property into the name of the
Indenture Trustee pursuant to Section 2.05.

         SECTION 2.07. Servicing Compensation; Payment of Certain Expenses by
                       the Servicer; Compensation Interest.

         On each Deposit Date, the Servicer shall be entitled to receive, by
withdrawal by the Servicer from the Collection Account, out of collections of
interest on the Mortgage Loans for 


                                       23
<PAGE>   28

the related Collection Period, as servicing compensation for such Collection
Period, the Monthly Servicing Fee, to the extent not retained by the Servicer
from amounts remitted to the Collection Account pursuant to Section 2.02(c)(i).
The Servicer shall also be entitled to retain any Ancillary Servicing
Compensation when received.

         The Servicer shall pay Compensating Interest to the Indenture Trustee
on behalf of the Bondholders out of the related Monthly Servicing Fee on each
Deposit Date, to the extent of the amount of the Monthly Servicing Fee, and
shall not be entitled to reimbursement therefor. The Servicer shall be required
to pay all expenses incurred by it in connection with its activities hereunder
(including payment of the fees and expenses relating to the Annual Independent
Public Accountant's Servicing Report described in Section 2.09, and all other
fees and expenses not otherwise expressly stated hereunder for the account of
the Bondholders) and shall not be entitled to reimbursement therefor except as
specifically provided herein.

         SECTION 2.08. Annual Statement as to Compliance.

                 (a) The Servicer will deliver to the Issuer, the Indenture
Trustee and each Rating Agency, with a copy to the Underwriter, on or before
March 31 of each year, beginning with March 31, 1999, an Officer's Certificate
of the Servicer substantially in the form set forth in Exhibit A hereto stating
that (1) a review of the activities of the Servicer during the preceding
calendar year (or since the Closing Date in the case of the first such
statement) and of its performance under this Agreement has been made under such
officer's supervision and (2) 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 since the Closing Date in the case of the
first such statement), or, if there has been a default in the fulfillment of any
such obligation, specifying each such default known to such officer and the
nature and status thereof.

                 (b) The Servicer shall deliver to the Issuer and the Indenture
Trustee, with a copy to each Rating Agency and to the Underwriter, promptly
after having obtained knowledge thereof, but in no event later than ten Business
Days thereafter, written notice by means of an Officer's Certificate of any
event that with the giving of notice or the lapse of time, or both, would become
an Event of Default.

         SECTION 2.09. Annual Independent Public Accountants' Servicing Report.

         On or before March 31 of each year, beginning with March 31, 1999, the
Servicer at its expense shall cause a firm of nationally recognized independent
public accountants (who may also render other services to the Servicer) to
furnish a report to the Issuer, the Indenture Trustee and each Rating Agency,
with a copy to the Underwriter, to the effect that such firm has examined
certain documents and records relating to the servicing activities of the
Servicer for the period covered by such report, and that such examination, which
has been conducted substantially in compliance with the Uniform Single
Attestation Program for Mortgage Bankers (to the extent that the procedures in
such audit guide are applicable to the servicing obligations set forth in this
Agreement), has disclosed no exceptions or errors in records relating to the


                                       24
<PAGE>   29

servicing activities of the Servicer that, in the opinion of such firm, are
material, except for such exceptions as shall be set forth in such report.

         SECTION 2.10. Access to Certain Documentation and Information Regarding
                       the Mortgage Loans.

                 (a) The Servicer shall provide to Bondholders that are
federally insured savings associations and the FDIC and its supervisory agents
and examiners access to the documentation regarding the Mortgage Loans required
by applicable regulations of the Office of Thrift Supervision, and to the
Issuer, the Indenture Trustee and their respective agents all documentation
relating to the Mortgage Loans that is in the possession of the Servicer, such
access being afforded without charge but only upon reasonable request and during
normal business hours at the offices of the Servicer. Nothing in this Section
2.10(a) 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 as
a result of such obligation shall not constitute a breach of this Section.

                 (b) The Servicer shall supply information to the Indenture
Trustee, upon reasonable advance notice, in such form as the Indenture Trustee
shall reasonably request, as is required in the Indenture Trustee's reasonable
judgment to enable the Indenture Trustee to make required payments and to
furnish the certificates, statements and reports to Bondholders as required of
the Indenture Trustee pursuant to the Indenture, it being understood that the
Servicer is responsible for supplying information concerning the Mortgage Loans
and not for any other information, including, without limitation, calculation of
payments due on the Bonds.

         SECTION 2.11. Maintenance of Fidelity Bond and Errors and Omissions
                       Policy.

         The Servicer shall during the term of its service as Servicer maintain
in force a (1) policy or policies of insurance covering errors and omissions in
the performance of its obligations as Servicer hereunder and (2) fidelity bond
in respect of its officers, employees and agents, in each case having coverage
amounts deemed by the Servicer to be adequate to its operations.

         SECTION 2.12. Notices to the Issuer, the Rating Agencies and the
                       Indenture Trustee.

         In addition to the other notices required to be given to the Issuer,
the Rating Agencies, and the Indenture Trustee by the provisions of this
Agreement, the Servicer shall give prompt notice to the Issuer, each Rating
Agency and the Indenture Trustee of (1) any amendment to this Agreement, (2) the
occurrence of an Event of Default and (3) the purchase of any Mortgage Loan
pursuant to Section 2.01 or 2.05 by the Servicer, as the case may be.

         SECTION 2.13. Reports of Foreclosures and Abandonment of Mortgaged
                       Properties.

         On or before February 28 of each year beginning in 1999, the Servicer
shall file the reports of foreclosures and abandonments of any Mortgaged
Property required by Code Section 6050J with the Internal Revenue Service and
provide a copy of such filing to the Indenture 


                                       25
<PAGE>   30

Trustee. The reports from the Servicer shall be in form and substance sufficient
to meet the reporting requirements imposed by such Section 6050J.

         SECTION 2.14. Sub-Servicers and Sub-Servicing Agreements.

                 (a) The Servicer may enter into Sub-Servicing Agreements for
any servicing and administration of Mortgage Loans with any institution that is
acceptable to the Indenture Trustee and that is in compliance with the laws of
each state necessary to enable it to perform its obligations under such
Sub-Servicing Agreement. The Servicer shall not enter into any Sub-Servicing
Agreement that does not provide for the servicing of the Mortgage Loans
specified therein on a basis consistent with the terms of this Agreement or that
otherwise violates the provisions of this Agreement. The Servicer may enter
into, and make amendments to, any Sub-Servicing Agreement or enter into
different forms of Sub-Servicing Agreements; provided, however, that any such
amendments or forms shall be consistent with and not violate the provisions of
this Agreement.

                 (b) For purposes of this Agreement the Servicer shall be deemed
to have received payments on Mortgage Loans when any Sub-Servicer has received
such payments. With respect to the Servicer's obligations under Section 2.01 to
make deposits into the Collection Account, the Servicer shall be deemed to have
made such deposits when any Sub-Servicer has made such deposits into a
Sub-Servicing Account if permitted by the related Sub-Servicing Agreement.

                 (c) Any Sub-Servicing Agreement and any other transactions or
services relating to the Mortgage Loans involving a Sub-Servicer shall be deemed
to be between the Sub-Servicer and the Servicer alone and the Indenture Trustee
shall not be deemed a party thereto and shall have no claims, rights,
obligations, duties or liabilities with respect to any Sub-Servicer, except that
the Indenture Trustee shall have such claims or rights that arise as a result of
any funds held by a Sub-Servicer in trust for or on behalf of the Trust Estate
and the Bondholders. Notwithstanding the execution of any Sub-Servicing
Agreement, the Servicer shall not be relieved of any liability hereunder and
shall remain obligated and liable for the servicing and administration of the
Mortgage Loans.

         SECTION 2.15. Annual Lien Opinions; Bond Redemptions.

                 (a) The Servicer shall procure, at its own expense, the
Opinions of Counsel required to be delivered annually to the Indenture Trustee
pursuant to Section 3.06 of the Indenture.

                 (b) In the event the Servicer exercises its right to redeem the
Bonds pursuant to Section 10.01 of the Indenture, the Servicer shall, at its own
expense, prepare all documents necessary for the Issuer to sign in connection
with such redemption, and deposit amounts required to be deposited by the Issuer
in connection with such redemption, in each case pursuant to Section 4.01 and
Article X of the Indenture, and shall advise the Issuer as to the actions it
must 


                                       26
<PAGE>   31
take in accordance with the Indenture in order to effect such redemption. The
Issuer shall follow all such directions of the Servicer.

         SECTION 2.16.  Year 2000 Program.

         Servicer has taken, or will by June 30, 1999 have taken, all steps
necessary and appropriate to prevent any problems in its computer and
information systems arising from or in connection with the information
processing challenges associated with the Year 2000, and will provide to the
Indenture Trustee such information and reports as the Indenture Trustee may
reasonably request from time to time with respect to such steps or have or will
be taken with respect thereto.


                                   ARTICLE III
                           SERVICER REMITTANCE REPORT

         SECTION 3.01.  Servicer Remittance Report.

         Not later than the third Business Day prior to each Deposit Date, the
Servicer shall deliver to the Issuer, the Indenture Trustee and the Underwriter
a computer-readable magnetic tape (the "Tape" for such month) and a series of
hard copy reports generally including the same information included on the Tape
(the "Report," and, together with the Tape, the "Servicer Remittance Report" for
such month) detailing the payments and collections received in respect of the
Mortgage Loans during the immediately preceding Collection Period. The Servicer
Remittance Report shall include loan-by-loan information that specifies account
number, borrower name, outstanding principal balance and activity for the
preceding Collection Period and Due Period, as applicable, and any other loan
level information sufficient to enable the Indenture Trustee to report the items
specified in "Payment Date Statement" in the Indenture, as well as (a) the
amount of prepayment penalties received on the Mortgage Loans during the related
Collection Period, (b) the information set forth on Exhibit E hereto as to
Mortgage Loans that became Liquidated Mortgage Loans during the related
Collection Period, and may be delivered in a separate report in the form of
Exhibit E hereto or as part of the Servicer Remittance Report and (c) any other
information regarding the Mortgage Loans as may from time to time be agreed to
by the Servicer and the Indenture Trustee. The Servicer shall only be required
to report information concerning the Mortgage Loans, and shall not be required
to calculate any required payments on the Bonds.


                                   ARTICLE IV
                     MONTHLY ADVANCES AND SERVICING ADVANCES

         SECTION 4.01.  Monthly Advances; Servicing Advances.

                  (a) Monthly Advances. On or before each Deposit Date, the
Servicer will transfer to the Indenture Trustee for deposit in the Bond Account,
in same day funds, an amount (a "Monthly Advance") equal to the sum of (1) with
respect to all Mortgage Loans for which the Monthly Payment due on the first day
of the month in which the Deposit Date occurs has not yet 


                                       27


<PAGE>   32


been paid, the amount of such late Monthly Payment (net of the Monthly Servicing
Fee attributable to such Mortgage Loan), plus (2) with respect to each Mortgaged
Property that was acquired in foreclosure or similar action (each, an "REO
Property") during or prior to the related Collection Period and as to which a
final sale did not occur during the related Collection Period, an amount equal
to the excess, if any, of the Monthly Payment that would have been due on the
related Mortgage Loan (net of the Monthly Servicing Fee attributable to such REO
Property) over the net income from such REO Property transferred to the Bond
Account for such Payment Date; provided, however, that in no case will the
Servicer be required to make advances with respect to any period following the
final due date with respect to any Mortgage Loan. All or a portion of any
Monthly Advance required to be made on a Deposit Date may be paid out of amounts
on deposit in the Collection Account that are not required to be transferred on
such Deposit Date to the Indenture Trustee for deposit into the Bond Account as
any portion of Remittable Funds for the related Deposit Date; provided, however,
that the Servicer shall be required to replace any such amounts by deposit into
the Collection Account on or before the next Deposit Date and the amount of such
deposit shall thereafter be considered a Monthly Advance for purposes of
reimbursement under this Agreement.

         The Servicer may recover Monthly Advances, if not theretofore recovered
from the Mortgagor on whose behalf such Monthly Advance was made, from
collections on the related Mortgage Loan, including Liquidation Proceeds,
Insurance Proceeds and such other amounts as may be collected by the Servicer
from the Mortgagor or otherwise relating to the Mortgage Loan. In addition, if
the Servicer determines, in its good faith business judgment, that a previously
made Monthly Advance has become a Nonrecoverable Advance, the Servicer may
reimburse itself for such Nonrecoverable Advances from amounts on deposit in the
Collection Account, regardless of whether such amounts are attributable to such
Mortgage Loan. Notwithstanding anything herein to the contrary, no Monthly
Advance need be made hereunder if such Monthly Advance would, if made,
constitute a Nonrecoverable Advance.

                  (b) Servicing Advances. The Servicer shall from time to
time during the term of this Agreement make such Servicing Advances as the
Servicer shall deem appropriate or advisable under the circumstances and are
required pursuant to the terms of this Agreement. Servicing Advances may be paid
by the Servicer out of amounts on deposit in the Collection Account from time to
time; provided, however, that the Servicer shall be required to replace any such
amounts by deposit into the Collection Account on or before the first Deposit
Date occurring after the payment of a Servicing Advance with such amounts, and
the amount of such deposit shall thereafter be considered a Servicing Advance
for purposes of reimbursement under this Agreement. All Servicing Advances made
by the Servicer shall be reimbursable from collections or recoveries relating to
the Mortgage Loans in respect of which such Servicing Advances have been made
including Liquidation Proceeds and Insurance Proceeds, and such other amounts as
may be collected by the Servicer from the Mortgagor, or from other amounts on
deposit in the Collection Account after the Servicer shall have determined, in
its good faith business judgment that such Servicing Advance has become a
Nonrecoverable Advance. Notwithstanding anything herein to the contrary, no
Servicing Advances need be made hereunder if such Servicing Advance would, if
made, constitute a Nonrecoverable Advance.

         SECTION 5.01.  Representations and Warranties of the Servicer.

         (a) The Servicer hereby represents and warrants to the Issuer and the
Indenture Trustee, that as of the Closing Date:

                  (i) The Servicer is a corporation duly organized, validly
         existing and in good standing under the laws of the State of Colorado.
         The Servicer is in compliance with the laws of each state in which it
         is acting as Servicer with respect to a Mortgage Loan to the extent
         necessary to perform all servicing obligations with respect to the
         related Mortgaged Property hereunder. The Servicer has the power and
         authority to execute and deliver this Agreement and to perform its
         obligations in accordance herewith. The execution, delivery and
         performance of this Agreement (including all instruments of transfer to
         be delivered pursuant to this Agreement) by the Servicer and the
         consummation of the transactions contemplated hereby have been duly and
         validly authorized by all necessary corporate action. This Agreement
         evidences the valid and binding obligation of the Servicer enforceable
         against the Servicer in accordance with its terms, subject to the
         effect of bankruptcy, insolvency, reorganization, moratorium and other
         similar laws relating to or affecting creditors' rights generally or
         the application of equitable principles in any proceeding, whether at
         law or in equity. The consummation of the transactions contemplated
         hereby will not result in the breach of any terms or provisions of the
         articles of incorporation or by-laws of the Servicer or result in the
         breach of any term or provision of, or conflict with or constitute a
         default under or result in the acceleration of any obligation under,
         any material agreement, indenture or loan or credit agreement or other
         material instrument to which the Servicer or its property is subject,
         or result in the violation of any law, rule, regulation, order,
         judgment or decree to which the Servicer or its property is subject.

                  (ii) All actions, approvals, consents, waivers, exemptions,
         variances, franchises, orders, permits, authorizations, rights and
         licenses required to be taken, given or obtained, as the case may be,
         by or from any federal, state or other governmental authority or
         agency, that are necessary in connection with the execution and
         delivery by the Servicer of this Agreement, have been duly taken, given
         or obtained, as the case may be, are in full force and effect, are not
         subject to any pending proceedings (administrative, judicial or
         otherwise) with respect to which the time within which any appeal
         therefrom may be taken or review thereof may be obtained has expired or
         no review thereof may be obtained or appeal therefrom taken, and are
         adequate to authorize the consummation of the transactions contemplated
         by this Agreement on the part of the Servicer and the performance by
         the Servicer of its obligations under this Agreement.

                  (iii) There is no action, suit, proceeding or investigation
         pending or, to the best of the Servicer's knowledge, threatened against
         the Servicer that, either in any one instance or in the aggregate,
         should reasonably be expected to result in any material 


                                       29


<PAGE>   34


         adverse change in the business, operations, financial condition,
         properties or assets of the Servicer or in any material impairment of
         the right or ability of the Servicer to carry on its business
         substantially as now conducted, or in any material liability on the
         part of the Servicer or that would draw into question the validity of
         this Agreement or the Mortgage Loans or of any action taken or to be
         taken in connection with the obligations of the Servicer contemplated
         herein, or that should be reasonably expected to impair the ability of
         the Servicer to perform under the terms of this Agreement.

                  (iv) The Servicer is not in default with respect to any order
         or decree of any court or any order, regulation or demand of any
         federal, state, municipal or governmental agency, which default should
         reasonably be expected to have consequences that would materially and
         adversely affect the condition (financial or other) or operations of
         the Servicer or its properties or to have consequences that should
         reasonably be expected to adversely affect its performance hereunder.

                  (v) The collection practices used by the Servicer are in all
         material respects legal and customary in the non-conforming mortgage
         loan servicing business.

                  (b) Upon discovery by any party hereto of a breach of any of
the foregoing representations and warranties that materially and adversely
affects the interests of the Bondholders, the party discovering such breach
shall give prompt written notice to the other parties hereto. Within 30 days of
its discovery or its receipt of notice of breach, the Servicer shall cure such
breach in all material respects.

         SECTION 5.02.  Liability of the Servicer.

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

         SECTION 5.03. Merger or Consolidation of, or Assumption of the
Obligations of, the Servicer.

         Any corporation or other entity (1) into which the Servicer may be
merged or consolidated, (2) that may result from any merger, conversion or
consolidation to which the Servicer shall be a party, or (3) that may succeed to
all or substantially all of the business of the Servicer, which corporation or
other entity shall be the successor to the Servicer under this Agreement without
the execution or filing of any document or any further act by any of the parties
to this Agreement; provided that if the Servicer is not the surviving entity, or
if the assumption by the surviving entity is not effective by operation of law,
then the surviving entity shall execute and deliver to the Issuer and the
Indenture Trustee an agreement of assumption to perform every obligation of the
Servicer hereunder.


                                       30


<PAGE>   35


         SECTION 5.04.  Limitation on Liability of the Servicer and Others.

         Neither the Servicer nor any of its directors, officers, employees or
agents shall be under any liability to the Issuer, the Indenture Trustee, the
Trust Estate, or the Bondholders for any action taken or for refraining from the
taking of any action by the Servicer 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 that would otherwise be
imposed by reason of willful misfeasance, bad faith or negligence in the
performance of the duties of the Servicer or by reason of reckless disregard of
the obligations and duties of the Servicer hereunder. The Servicer and any
director, officer, 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 shall not be under
any obligation to appear in, prosecute or defend any legal action that is not
incidental to its duties to service the Mortgage Loans in accordance with this
Agreement, and that in its opinion may involve it in any expense or liability.

         SECTION 5.05.  Servicer Not to Resign.

         Subject to the provisions of Section 5.03 regarding the merger or
consolidation of the Servicer into or with another entity, the Servicer shall
not resign from the obligations and duties hereby imposed on it except upon
determination that the performance of its duties or obligations hereunder is no
longer permissible under applicable law or regulation or are in material
conflict by reason of applicable law or regulation with any other activities
carried on by it at the date of this Agreement. Any such determination
permitting the resignation of the Servicer pursuant to this Section shall be
evidenced by an Opinion of Counsel to such effect delivered to the Indenture
Trustee obtained by the Servicer at its own expense. No resignation pursuant to
this Section 5.05(a) shall become effective until the Indenture Trustee or a
successor servicer shall have assumed the responsibilities and obligations of
the Servicer in accordance with Section 6.02 or (b) shall relieve the Servicer
of responsibility for any obligations pursuant to this Agreement that
specifically survive the resignation or termination of the Servicer. Each of the
Rating Agencies shall be given written notice of a resignation of the Servicer
pursuant to this Section.

         Notwithstanding the foregoing, the Servicer may resign effective upon
its appointment of a successor the appointment of whom has been approved by the
Indenture Trustee in writing, but only if each Rating Agency shall have
confirmed in writing that the appointment of such successor will not result in
the downgrading of the then-current implied ratings assigned by them to the
Bonds.


                                   ARTICLE VI
                                     DEFAULT

         SECTION 6.01.  Events of Default.

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


                                       31


<PAGE>   36


                  (a) Any failure by the Servicer to (1) make a required Monthly
Advance on the related Deposit Date or (2) deposit into the Collection Account
or transfer to the Indenture Trustee for deposit in the Bond Account any other
amount required to be deposited therein under this Agreement on the related
Deposit Date, which failure, in the case of only clause (2) hereof, is not
remedied by the close of business on the Business Day after the date upon which
written notice of such failure shall have been given to the Servicer by the
Indenture Trustee or to the Servicer and the Indenture Trustee by Holders of
Bonds evidencing Voting Interests represented by all Bonds aggregating not less
than 51%;

                  (b) 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 this Agreement or in the Mortgage Loan Sale Agreement,
which failure (1) materially and adversely affects the Bondholders and (2)
continues unremedied for a period of 30 days after the date on which written
notice of such failure (which notice shall refer specifically to this Section),
requiring the same to be remedied, shall have been given to the Servicer by the
Indenture Trustee or to the Servicer by the Holders of Bonds evidencing Voting
Interests represented by all Bonds aggregating not less than 51%.

                  (c) 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, 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;

                  (d) The consent by the Servicer to the appointment of a
trustee, conservator or receiver or liquidator in any bankruptcy, insolvency,
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 admission by the Servicer in writing of its
inability to pay its debts generally as they become due, the Servicer's filing
of a petition to take advantage of any applicable bankruptcy, insolvency or
reorganization statute, the Servicer's making of an assignment for the benefit
of its creditors, or the Servicer's voluntary suspension of payment of its
obligations; or

                  (e) The occurrence of a Cumulative Loss Rate Percentage in
excess of 7.0%. 

then, and in each and every such case, so long as such Event of Default shall
not have been remedied by the Servicer, either the Indenture Trustee or the
Holders of Bonds evidencing Voting Interests represented by all Bonds
aggregating not less than 51%, by notice then given in writing to the Servicer
with a copy to the Indenture Trustee, may terminate all of the rights,
responsibilities and obligations of the Servicer as servicer under this
Agreement. 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 Mortgage Loans or otherwise, shall pass to and be vested in the Indenture
Trustee (unless a successor Servicer has been appointed pursuant to Section
6.02) pursuant to and under this Section and, without limitation, the Indenture
Trustee or 



                                       32



<PAGE>   37


successor Servicer 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 the Mortgage Notes and
related documents, or otherwise. Notwithstanding anything herein to the
contrary, the Indenture Trustee shall not be deemed to have notice of an Event
of Default unless and until a Responsible Officer of the Indenture Trustee (x)
has actual knowledge of the occurrence of such Event of Default or (y) has
received a notice of the occurrence of such Event of Default from the Servicer
pursuant to Section 2.12 hereof and the Indenture Trustee shall not be in
default of its obligations hereunder with respect to any failure to give a
default notice to the Servicer in the absence of either actual knowledge on the
part of a Responsible Officer of the Indenture Trustee or the receipt of such
notice from the Servicer. The Servicer agrees to cooperate with the Indenture
Trustee in effecting the termination of its responsibilities and rights as
Servicer hereunder, including, without limitation, the transfer to the Indenture
Trustee or successor Servicer for the administration by it of all cash amounts
that shall at the time be held by the Servicer that have been deposited by the
Servicer in the Collection Account or transferred to the Indenture Trustee for
deposit into the Bond Account or thereafter received by the Servicer with
respect to the Mortgage Loans.

         The Indenture Trustee shall notify the Servicer in writing immediately
upon its becoming aware of a default described in Section 6.01(a).

         All reasonable costs and expenses (including attorneys' fees) incurred
in connection with transferring the Servicer Mortgage Files to a successor
Servicer, amending this Agreement to reflect the appointment of a successor as
Servicer pursuant to this Section 6.01 or otherwise in connection with the
assumption by a successor Servicer of the duties of the predecessor Servicer
hereunder shall be paid by the predecessor Servicer upon presentation of
reasonable documentation of such costs and expenses.

         SECTION 6.02.  Indenture Trustee to Act; Appointment of Successor.

         On and after the time the Servicer receives a notice of termination
pursuant to Section 6.01, the Indenture Trustee shall appoint a successor
Servicer meeting the criteria described below and, if it does not appoint a
successor, or until the successor's appointment takes effect, the Indenture
Trustee shall be the successor in all 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,
including without limitation, the obligation to make Monthly Advances and to pay
Compensating Interest. As compensation therefor, the Indenture Trustee shall be
entitled to such compensation as the Servicer would have been entitled to
hereunder if no such notice of termination had been given. In the event the
Indenture Trustee fails to appoint a successor Servicer, and the Indenture
Trustee is unwilling or legally unable to act as successor Servicer itself, it
may petition a court of competent jurisdiction to appoint, any established
housing and home finance institution or any institution that regularly services
non-conforming


                                       33


<PAGE>   38


residential mortgage loans that is then servicing a non-conforming residential
mortgage loan portfolio and having all licenses, permits and approvals required
by applicable law, and having a net worth of not less than $10,000,000, 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; provided that
the appointment of any such successor Servicer will not result in the
qualification, reduction or withdrawal of the then current ratings assigned to
the Bonds by any Rating Agency. Pending appointment of a successor to the
Servicer hereunder, unless the Indenture Trustee is prohibited by law from so
acting, the Indenture Trustee shall act in such capacity as hereinabove
provided. In connection with such appointment and assumption, the Indenture
Trustee may make such arrangements for the compensation of such successor out of
payments on Mortgage Loans as it and such successor shall agree; provided,
however, that no such compensation shall be in excess of that permitted the
Servicer hereunder. The Indenture Trustee and such successor shall take such
action, consistent with this Agreement, as shall be necessary to effect any such
succession. The appointment of a successor Servicer shall not affect any
liability of the predecessor Servicer that may have arisen under this Agreement
prior to its termination as Servicer, nor shall any successor Servicer be liable
for any acts or omissions of the predecessor Servicer or for any breach by such
Servicer or the Issuer of any of its representations or warranties contained
herein or in any related document or agreement. Each of the Rating Agencies
shall be given written notice of the appointment of a successor Servicer
pursuant to this Section.

         SECTION 6.03.  Notifications to Bondholders.

         Upon any termination or appointment of a successor to the Servicer
pursuant to this Article Six, the Indenture Trustee shall give prompt written
notice thereof to Bondholders at their respective addresses appearing in the
Bond Register, the Issuer and to each Rating Agency.

         Within 60 days of obtaining actual knowledge of the occurrence of any
Event of Default that remains uncured, the Indenture Trustee shall transmit by
mail to all Bondholders notice of such Event of Default.

         SECTION 6.04. Assumption or Termination of Sub-Servicing Agreements by
the Indenture Trustee or Any Successor Servicer.

         Upon the termination of the Servicer as servicer under this Agreement,
the Indenture Trustee as successor to the Servicer hereunder or any other
successor to the Servicer hereunder may, subject to the terms of any
Sub-Servicing Agreement, in its sole and absolute discretion elect to assume or
terminate any Sub-Servicing Agreement then in force and effect between the
Servicer and the Sub-Servicer. Notwithstanding the foregoing, any termination
fee due to a Sub-Servicer because of its termination by the Indenture Trustee
hereunder shall be the responsibility of the terminated Servicer and not the
Indenture Trustee. Upon the assumption of any Sub-Servicing Agreement, the
terminated Servicer agrees to deliver to the assuming party any and all
documents and records relating to the applicable Sub-Servicing Agreement and an
accounting of amounts collected and held by it and otherwise use its best
reasonable efforts to effectuate the orderly transfer of the Sub-Servicing
Agreement.

         SECTION 6.05.  Payment of Indenture Trustee's Fees and Expenses.

                  (a) On each Payment Date, the Indenture Trustee will be
entitled to retain its Indenture Trustee Fee from amounts deposited into the
Bond Account on the related Deposit Date. The Indenture Trustee Fee constitutes
compensation for all services rendered by the Indenture Trustee in the exercise
and performance of any of the powers and duties hereunder or under the
Indenture. The Indenture Trustee does not and will not have any lien on the
Trust Estate for payment of any such fees or expenses.

                  (b) The Servicer shall pay or reimburse the Indenture Trustee,
from its own funds, upon its request for all reasonable expenses, disbursements
and advances incurred or made by the Indenture Trustee (as Indenture Trustee or
as Manager) in accordance with any of the provisions of this Agreement, the
Indenture and the Management Agreement, dated as of June 1, 1998, between the
Issuer and Norwest Bank Minnesota, National Association, as manager (the
"Management Agreement"), (including but not limited to 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 that is otherwise
reimbursed to the Indenture Trustee, and except for routine, recurring or
nominal expenses, disbursements and advances; provided, however, that the
Indenture Trustee shall not refuse to perform any of its duties hereunder or
under the Indenture or the Management Agreement solely as a result of the
failure of the Servicer to pay or reimburse such expenses, disbursements or
advances.

                  (c) The Servicer agrees to indemnify the Indenture Trustee,
Paying Agent, and their respective agents, directors, employees and officers
(each an "Indemnified Party") from, and hold it harmless against, any and all
losses and liabilities, damages, claims or expenses (including reasonable
attorneys' fees, expenses and disbursements), incurred or in connection with
this Agreement, the Indenture, the Bonds or the Management Agreement, including,
but not limited to, any such loss, liability or expense incurred, arising in
respect of or in connection with any legal action against the Trust Estate, the
Issuer or the Indenture Trustee or any director, officer, employee or agent
thereof, or the performance of any of the Indenture Trustee's duties hereunder
(except in the event it assumes the duties and obligations of the Servicer
hereunder as the result of an Event of Default), the Indenture or the Management
Agreement, other than any loss, liability or expense incurred by reason of the
negligence, bad faith or intentional misconduct of the Indenture Trustee.
Notwithstanding the generality of the foregoing, if any action, suit or other
proceeding is brought against an Indemnified Party for which the Indemnified
Party seeks indemnification hereunder, the Indemnified Party shall promptly
notify the Servicer of the commencement thereof, whereupon the Servicer will be
entitled to participate therein, and to assume the defense thereof, with counsel
selected by the Servicer and reasonably satisfactory to such Indemnified Party;
provided, that, if in the Indemnified Party's reasonable judgment the
Indemnified Party has any claims or defenses that conflict with or differ from
the interests of the Servicer, the Indemnified Party shall be entitled to select
counsel of its choosing and pursue such claims and defenses separately and all
related costs, expenses and liabilities associated with such separate claims or
defenses will continue to be covered by the Servicer's indemnification


                                       35

obligation hereunder. The Servicer shall not be entitled to settle any
proceeding without the consent of any Indemnified Party with any right of
indemnification hereunder with respect to such proceeding except upon such terms
as will provide each such Indemnified Party reasonable assurance of full
indemnity hereunder.

                  (d) This Section 6.05 shall survive the termination of this
Agreement or the resignation or removal of the Indenture Trustee or the Servicer
as regards rights accrued prior to such resignation or removal.

                  (e) Amounts required to be paid by the Servicer to the
Indenture Trustee under subsections (b) and (c) above shall be paid by the
Servicer out of its own funds, and shall not be reimbursable to the Servicer
from the Collection Account or netted by the Servicer out of funds it is
required to deposit into the Collection Account.


                                   ARTICLE VII
                                   TERMINATION

         SECTION 7.01.  Termination.

         Except as otherwise specifically set forth herein, the obligations and
responsibilities of the Servicer shall terminate upon the earliest to occur of
(1) the final payment or other liquidation of the Mortgage Loans and the
disposition of all REO Properties and the remittance of all funds due hereunder
with respect to such Mortgage Loans and REO Properties and (2) the satisfaction
and discharge of the indebtedness evidenced by the Bonds and the termination of
the Deposit Trust Agreement.


                                  ARTICLE VIII
                            MISCELLANEOUS PROVISIONS

         SECTION 8.01.  Amendment.

         This Agreement may be amended at any time and from time to time by the
Servicer, the Issuer and the Indenture Trustee, without the consent of any of
the Bondholders, (1) to cure any error or any ambiguity or to correct or
supplement any provisions herein which may be inconsistent with any other
provisions herein, or (2) to comply with the requirements of the Code; provided
that in all such cases the Indenture Trustee shall have received written
confirmation from each Rating Agency that any such modifications to this
Agreement will not result in a qualification, reduction or withdrawal of the
current ratings assigned to the Bonds by such Rating Agency.

         This Agreement may also be amended at any time and from time to time by
the Servicer, the Issuer and the Indenture Trustee, with the consent of Holders
of Bonds evidencing Voting Interests of the Bonds affected thereby aggregating
greater than 50%, for the purpose of adding any provisions to or changing in any
manner or eliminating any of the provisions of this Agreement, or of modifying
in any manner the rights of the Holders of Bonds of such Bonds; 


                                       36


<PAGE>   41


provided, however, that no such amendment shall (1) reduce in any manner the
amount of, or delay the timing of, collections of payments on Mortgage Loans or
payments which are required to be deposited into the Bond Account without the
consent of all Bondholders or (2) reduce the aforesaid percentage of the Bonds
the Holders of which are required to consent to any such amendment, without the
consent of the Holders of all Bonds then outstanding.

         Promptly after the execution of any such amendment or consent pursuant
to the second preceding paragraph, the Indenture Trustee shall furnish written
notification of the substance of such amendment to each Bondholder and an
executed copy of such amendment to each Rating Agency, with a copy to the
Underwriter.

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

         Prior to the execution of any amendment to this Agreement, the
Indenture Trustee shall be entitled to receive and rely upon an Opinion of
Counsel furnished by and at the expense of the party requesting such amendment
stating that the execution of such amendment is authorized or permitted by this
Agreement. The Indenture Trustee may, but shall not be obligated to, enter into
any such amendment that affects the Indenture Trustee's own rights, duties or
immunities under this Agreement.

         SECTION 8.02.  Governing Law.

         This Agreement shall be construed in accordance with the laws of the
State of New York (without regard to conflict of laws principles and the
application of the laws of any other jurisdiction), and the obligations, rights
and remedies of the parties hereunder shall be determined in accordance with
such laws.

         SECTION 8.03.  Notices.
