(the "Commission") on May 14, 1992, as amended by Amendment No. 1 thereto filed
with the Commission on August 7, 1992, as further amended by Post Effective
Amendment No. 1 thereto filed with the Commission on August 17, 1994
(collectively, the "Registration Statement"), pursuant to which the Registrant
registered $2,000,000,000 aggregate principal amount of its collateralized
mortgage obligations, issuable in various series, for sale in accordance with
the provisions of the Securities Act of 1933, as amended (the "Act"). Reference
is also hereby made to the Prospectus dated September 26, 1997 and the related
Prospectus Supplement, dated September 26, 1997 (collectively, the

         On September 30, 1997, the Registrant caused the issuance and sale of
$281,194,911 aggregate initial principal amount of Securities. The Securities
are collateralized by mortgage pass-through certificates (the "Conventional
Certificates") evidencing the beneficial ownership interest in entire pools of
certain conventional, fixed-rate, fully- amortizing, one-to four-family, first
lien mortgage loans (the "Mortgage Loans") originated or acquired by North
American Mortgage Company ("NAMC"). The Certificates were created pursuant to a

Servicing Agreement") by and among the Registrant, as Depositor, NAMC, as
Master Servicer, and The First National Bank of Chicago, as Certificate
Trustee. A copy of the Pooling and Servicing Agreement is filed herewith as
Exhibit 10.1. The Securities were issued pursuant to an Indenture dated as of
September 1, 1997 (the "Indenture"), as supplemented by the Series 1997-NAMC 3
Supplement thereto dated as of September 30, 1997 (the "Series Supplement"),
each by and between the Registrant and The First National Bank of Chicago, as
Indenture Trustee. A copy of the Indenture is filed herewith as Exhibit 4.1 and
a copy of the Series Supplement is filed herewith as Exhibit 4.2. The Mortgage
Loans were sold by NAMC to DLJ Mortgage Capital, Inc. ("DLJMCI") pursuant to a
Seller's Purchase, Warranties and Servicing Agreement dated as of September 15,
1997 between NAMC and DLJMCI, and were subsequently sold by DLJMCI to the
Registrant pursuant to an Assignment and Assumption Agreement dated as of
September 30, 1997 between DLJMCI and the Registrant.

         The Offered Securities (as defined in the Prospectus), having an
aggregate principal balance of $278,242,362, have been sold by the Registrant
to Donaldson, Lufkin & Jenrette Securities Corporation ("DLJSC") pursuant to an
Underwriting Agreement dated as of September 26, 1997 (the "Underwriting
Agreement"), as supplemented by a Terms Agreement dated as of September 26,
1997, each among DLJSC, the Registrant and Capstead Mortgage Corporation
("CMC"). A copy of the Underwriting Agreement is filed herewith as Exhibit 1.1.
The Class B-4, Class B-5 and Class B-6 Securities (as defined in the
Prospectus) have been sold by the Registrant to DLJSC pursuant to a Purchase
Agreement dated September 29, 1997, by and among DLJSC, the Registrant and CMC.

                             UNDERWRITING AGREEMENT


                                                              September 24, 1997


Donaldson, Lufkin & Jenrette
  Securities Corporation
277 Park Avenue
New York, New York  10172

Ladies and Gentlemen:

         CMC Securities Corporation IV (the "Company"), a Delaware corporation
and wholly-owned subsidiary of Capstead Mortgage Corporation, a Maryland
corporation ("Capstead"), proposes to issue its Collateralized Mortgage
Obligations of the series (each, a "Series") and classes designated at the time
of sale (the "Bonds").  The Bonds shall be issued under an indenture, dated as
of September  1, 1997 (the "Original Indenture"), between the Company and The
First National Bank of Chicago, as trustee (the "Trustee"), as supplemented
from time to time by one or more supplemental indentures, each providing for
the issuance of a Series of Bonds (the "Series Supplements") between the
Company and the Trustee.  Such Original Indenture, as supplemented from time to
time hereafter, and as supplemented by the Series Supplements, with any changes
therein made with your consent, and, with your consent any other indenture is
herein referred to as the "Indenture."  Capstead joins this agreement for the
purposes set forth herein.

         Underwritten Offerings of Bonds may be made through you or through an
underwriting syndicate managed by you.  The Company proposes to sell one or
more Series of the Bonds or certain Classes of Bonds of one or more Series to
you and to each of the other several underwriters, if any, participating in an
underwriting syndicate managed by you.  It is understood, however, that the
Company may elect to retain, through the execution of one or more underwriting
agreements in addition to this Agreement, one or more additional underwriters
other than you to underwrite, or manage the underwriting syndicate with respect
to, any offering of one or more Series of its Bonds.
<PAGE>   2
         Whenever the Company determines to make such an offering of Bonds
through you, it will enter into an agreement (the "Terms Agreement") providing
for the sale of such Bonds to, and the purchase and offering thereof by, you
and such other underwriters, if any, selected by you as have authorized you to
enter into such Terms Agreement on their behalf (the underwriters designated in
any such Terms Agreement being referred to herein as "Underwriters," which term
shall include you whether acting alone in the sale of any Series of Bonds or as
a member of the underwriting syndicate).  The Terms Agreement relating to each
offering of Bonds shall specify the principal amount of Bonds to be issued and
their terms not otherwise specified in the Indenture, a brief description of
the Conventional Certificates (as defined below) to be pledged as security
therefor, the names of the Underwriters participating in such offering (subject
to substitution as provided in Section 11 hereof) and the principal amount of
the Bonds which each severally agrees to purchase, the names of such other
Underwriters, if any, acting as co-managers with you in connection with such
offering, the price at which the Bonds are to be purchased by the Underwriters
from the Company, the initial public offering price (or the manner in which
such prices shall be determined), the time and place of delivery of and payment
for the Bonds, and such other information as may be agreed upon.  The Terms
Agreement, which shall be substantially in the form of Exhibit A hereto, may
take the form of an exchange of any standard form of written telecommunication
between you and the Company.  Each offering of Bonds through you will be
governed by this Agreement, as supplemented by the applicable Terms Agreement,
and this Agreement and such Terms Agreement shall inure to the benefit of and
be binding upon each Underwriter participating in the offering of such Bonds.

         At their date of issuance, the Bonds of each Series underwritten by
you will be secured by a pledge to the Trustee of, among other things,
Conventional Certificates (as defined in the Indenture) (collectively, the
"Conventional Certificates").  The Bonds are more fully described in the
Registration Statement (as defined below).  Capitalized terms used but not
defined herein shall have the meanings given to them in the Indenture.

         The Company has filed with the Securities and Exchange Commission (the
"Commission") a registration statement on Form S-3 (No. 33-47912), a related
preliminary prospectus and related preliminary prospectus supplements for the
registration of the Bonds under the Securities Act of 1933 (the "1933 Act"),
which registration statement, as most recently amended, was declared effective
on August 18, 1994.  Such registration statement, as from time to time amended
through the date of the Terms Agreement, including all exhibits thereto and all
documents therein incorporated by reference from time to time pursuant to Item
12 of Form S-3 under the 1933 Act that were filed under the Securities Exchange
Act of 1934 (the "1934 Act"), on or before the effective date of such
registration statement, but excluding the Statement of Eligibility and
Qualification (Form T-1) under the Trust Indenture Act of 1939 (the "1939
Act"), is hereinafter referred to as the "Registration Statement."  The
prospectus in the form in which it appears in the Registration Statement,
including all documents therein incorporated by reference from time to time
pursuant to the 1934 Act, is hereinafter referred to as the "Basic Prospectus".
The Basic Prospectus as





                                     --2--
<PAGE>   3
supplemented by the prospectus supplement or supplements relating to a
particular Series of the Bonds each in the form first filed after the date of
the related Terms Agreement with the Commission pursuant to Rule 424 under the
1933 Act, including any documents incorporated by reference therein pursuant to
Item 12 of Form S-3 under the 1933 Act that were filed under the 1934 Act on or
before the date of such prospectus supplement (such prospectus supplement,
including such incorporated documents, in the form first filed after the date
of the related Terms Agreement pursuant to Rule 424(b) being hereinafter termed
the "Prospectus Supplement"), is hereinafter referred to as the "Final
Prospectus".  Any reference herein to the terms "amend", "amendment" or
"supplement" with respect to the Registration Statement, the Final Prospectus
or the Prospectus Supplement shall be deemed to refer to and include the filing
of any document under the 1934 Act after the effective date of the Registration
Statement or the issue date of the Final Prospectus or Prospectus Supplement,
as the case may be, deemed to be incorporated therein by reference pursuant to
Item 12 of Form S-3 under the 1933 Act.

         SECTION  1.      Representations and Warranties.  The Company and
Capstead, jointly and severally, represent and warrant to you as of the date
hereof, and to each Underwriter named in a Terms Agreement as of the date
thereof (in each case the "Representation Date"), as follows:

                 (a)      The Registration Statement, at the time it became
         effective, complied and, as of the date hereof, does comply, in all
         material respects with the requirements of the 1933 Act and the rules
         and regulations of the Commission thereunder (the "1933 Act
         Regulations") and will not contain an untrue statement of a material
         fact or omit to state a material fact required to be stated therein or
         necessary to make the statements therein not misleading, and the Final
         Prospectus at the time it is mailed to the Commission for filing
         pursuant to Rule 424 under the Act and at the Closing Time referred to
         in Section 2 will not contain an untrue statement of a material fact
         or omit to state a material fact necessary in order to make the
         statements therein, in the light of the circumstances under which they
         were made, not misleading; provided, however, that the representations
         and warranties in this subsection shall not apply to statements in or
         omissions from (i) the Registration Statement or Final Prospectus made
         in reliance upon and in conformity with information furnished to the
         Company in writing by any Underwriter through you expressly for use in
         the Registration Statement or Final Prospectus or (ii) the Current
         Report (as defined in Section 3(b) below), or in any amendment thereof
         or supplement thereto, incorporated by reference in such Registration
         Statement or such Final Prospectus (or any amendment thereof or
         supplement thereto).  There are no material contracts or documents of
         the Company which are required to be filed as exhibits to the
         Registration Statement by the 1933 Act or the 1933 Act Regulations
         which have not been so filed.

                 (b)      At the time the Registration Statement became
         effective the Trustee was duly qualified under the requirements of the
         1939 Act and the rules and regulations of the Commission thereunder
         (the "1939 Act Regulations"), and at the Closing Time the Indenture





                                     --3--
<PAGE>   4
         will be so qualified and will conform in all material respects with
         the requirements of the 1939 Act and the 1939 Act Regulations.

                 (c)      The documents incorporated by reference in the
         Registration Statement and the applicable Final Prospectus, at the
         time they were or hereafter are filed with the Commission, complied
         and will comply in all material respects with the requirements of the
         1934 Act and the rules and regulations of the Commission thereunder,
         and, when read together and with the other information in the
         applicable Final Prospectus, at the time the Registration Statement
         and any amendments thereof became effective, and at the time such
         Final Prospectus is filed with the Commission, did not and will not
         contain an untrue statement of a material fact or omit to state a
         material fact required to be stated therein or necessary to make the
         statements therein, in the light of the circumstances under which they
         were made, not misleading; provided, however, that the representations
         and warranties in this subsection shall not apply to the Current
         Report.

                 (d)      The accountants who reported on the balance sheet
         included or incorporated by reference in the Registration Statement
         are independent public accountants as required by the 1933 Act and the
         1933 Act Regulations.

                 (e)      The balance sheet of the Company included or
         incorporated by reference in the Registration Statement presents
         fairly the financial position of the Company at the date indicated,
         and has been prepared in conformity with generally accepted accounting
         principles.

                 (f)      Since the respective dates as of which information is
         given in the Registration Statement or, if later, the applicable Final
         Prospectus, except as otherwise stated therein, there has been no
         material adverse change in the condition, financial or otherwise,
         earnings, business affairs, or business prospects of the Company.

                 (g)      The Company has been duly incorporated and is validly
         existing as a corporation in good standing under the laws of the State
         of Delaware with power and authority (corporate and other) to own,
         lease and operate its properties and conduct its business as described
         in the Registration Statement, and, at the Closing Time, the Company
         will be duly qualified as a foreign corporation to transact business
         and will be in good standing in the State of Texas.  The Company is
         not required to qualify to do business as a foreign corporation under
         the laws of any other state.  The Company has no subsidiaries.

                 (h)      The authorized, issued and outstanding capital stock
         of the Company is as set forth (or incorporated) in the Registration
         Statement, and the shares of issued and outstanding capital stock of
         the Company have been duly authorized and validly issued and are fully
         paid and non-assessable, and are owned of record and beneficially by
         Capstead, free





                                     --4--

         and clear of any lien, charge, option, warrant, security interest,
         encumbrance, voting trust or similar arrangement.

                 (i)      Neither the Company nor Capstead is in violation of
         its charter or bylaws.  The Company is not in default in the
         performance or observance of any obligation, agreement, covenant or
         condition contained in any contract, indenture, mortgage, loan
         agreement, note, lease or other instrument to which it is a party or
         by which it or its properties may be bound, which violations or
         defaults separately or in the aggregate would have a material adverse
         effect on the Company.

                 (j)      The Company owns or possesses or has obtained all
         material governmental licenses, permits, consents, orders, approvals
         and other authorizations necessary to lease, own or license, as the
         case may be, and to operate, its properties and to carry on its
         business as described in the Registration Statement or, if later, the
         applicable Final Prospectus; and the Company has conducted and is
         conducting its business so as to comply in all material respects with
         all applicable laws, administrative regulations and administrative and
         court decrees.

                 (k)      There is no action, suit or proceeding before or by
         any court or governmental agency or body, domestic or foreign, now
         pending against the Company or, to the knowledge of the Company and
         Capstead, threatened against the Company (except as set forth in the
         Registration Statement or, if later, the applicable Final Prospectus)
         which could reasonably be expected to result in any material adverse
         change in the condition, financial or otherwise, earnings, business
         affairs, or business prospects of the Company which could reasonably
         be expected to interfere with or materially and adversely affect the
         consummation of the transactions contemplated herein.

                 (l)      The execution and delivery of this Agreement and the
         Indenture, the incurrence of the obligations herein set forth and the
         consummation of the transactions contemplated herein and therein have
         been, and the execution and delivery of each Terms Agreement and the
         consummation of the transactions contemplated therein will have been
         (before the issuance of the related Bonds), duly authorized by the
         Company and/or Capstead, as applicable, by all necessary action
         (corporate and other); this Agreement and the Indenture have been, and
         the Terms Agreement, when executed and delivered, will have been, duly
         executed and delivered by the Company, and/or Capstead, as applicable,
         enforceable in accordance with their terms, subject, as to
         enforceability of remedies, to applicable bankruptcy, insolvency,
         reorganization, or other laws affecting creditors' rights generally,
         and to general principles of equity and equitable remedies (regardless
         of whether the enforceability of such remedies is considered in a
         proceeding in equity or at law).  Neither the execution and delivery
         of this Agreement, the Indenture or the Terms Agreement, the
         incurrence of the obligations herein or therein set forth, nor the
         consummation of the





                                     --5--
<PAGE>   6
         transactions contemplated herein or therein will conflict with or
         constitute a breach of, or default under, or result in the creation or
         imposition of any lien, mortgage, pledge, charge, security interest or
         encumbrance (collectively, "Lien") upon any property or assets of the
         Company or Capstead, as applicable, pursuant to any contract,
         indenture, mortgage, loan agreement, note, lease or other instrument
         to which the Company or Capstead, as applicable, is a party or by
         which any of them may be bound, or to which any of the property or
         assets of any of them is subject (other than the Lien created pursuant
         to the Indenture), which separately or in the aggregate are material,
         nor will any such action result in any violation of the provisions of
         the charter or bylaws of either of the Company or Capstead, or, to the
         best of such entity's knowledge, of any law, administrative regulation
         or administrative or court decree.

                 (m)      The issuance of the Bonds underwritten by you has
         been duly authorized by the Company (or will have been so authorized
         prior to each issuance of Bonds underwritten by you) and, when such
         Bonds are executed and authenticated and delivered in accordance with
         the Indenture and sold to the Underwriters pursuant to this Agreement
         and any Terms Agreement, such Bonds will be entitled to the benefits
         and security provided by the Indenture and will constitute the legal,
         valid and binding non-recourse obligations of the Company enforceable
         in accordance with their terms, but otherwise subject, as to
         enforceability of remedies, to applicable bankruptcy, insolvency,
         reorganization or other laws affecting creditors' rights generally,
         and to general principles of equity and equitable remedies (regardless
         of whether the enforceability of such remedies is considered in a
         proceeding in equity or at law).

                 (n)      The Bonds of each Series underwritten by you and the
         Indenture will conform in all material respects to the respective
         descriptions thereof contained in the applicable Final Prospectus,
         except that no representation or warranty is made that the Bonds
         conform with any description thereof contained in the Current Report.

                 (o)      At the Closing Time with respect to a Series of
         Bonds, the Company will own (i) the Conventional Certificates listed
         in Schedule A to the Series Supplement relating to the applicable
         Series of Bonds and (ii) the money or other assets specified or
         referred to in the granting clauses of such Series Supplement as being
         pledged to the Trustee at Closing Time (together, the "Initial
         Collateral"), free and clear of any Lien, except the Lien of the
         Indenture; the Company has power and authority (corporate and other)
         to assign, pledge and deliver the Initial Collateral to the Trustee
         under the Indenture, and will have duly authorized such assignment,
         pledge and delivery to the Trustee by all necessary corporate action.

                 (p)      As of the Closing Time with respect to a Series of
         Bonds, the Company will have assigned, pledged and delivered to the
         Trustee under the Indenture all of its right, title and interest in
         and to, among other things, (i) Conventional Certificates with an
         aggregate





                                     --6--
<PAGE>   7
         outstanding principal balance as of such Closing Time at least equal
         to the aggregate original principal amount of the Bonds of the
         applicable Series then being issued and (ii) cash and/or other assets,
         if any, in the amount set forth in the related Series Supplement.

                 (q)      At the Closing Time with respect to a Series of
         Bonds, each Conventional Certificate listed on Schedule A to the
         Series Supplement relating to the applicable Series of Bonds will have
         been duly and validly assigned, pledged and delivered to the Trustee,
         or its nominee, and together with such assignment, pledge and delivery
         of each Conventional Certificate, the filing of a UCC-1 financing
         statement with respect to the Conventional Certificates in the office
         of the Secretary of State of the State of Texas and in such other
         jurisdictions, if any, as the Company deems appropriate and the
         possession by the Trustee, or its nominee, of the Conventional
         Certificates and of the monies and/or other assets, if any, specified
         in the related Series Supplement, will create as security for
         repayment of the Bonds a valid, perfected first security interest.
         The information set forth with respect to the Conventional
         Certificates in Schedule A to the related Series Supplement will as of
         the Closing Time of such Series be true and correct in all material
         respects.

                 (r)      The Company is not, and will not as a result of the
         offer and sale of the Bonds as contemplated in this Agreement and any
         applicable Terms Agreement become, an "investment company" or under
         the "control" of an "investment company" as such terms are defined in
         the Investment Company Act of 1940, as amended (the "Investment
         Company Act") which would be required to register under the Investment
         Company Act.

                 (s)      The representations and warranties made by the
         Company in the Indenture and made in any Officers' Certificate of the
         Company delivered pursuant to the Indenture will be true and correct
         at the time made and at the Closing Time.

                 (t)      The Pooling and Servicing Agreement, the Conventional
         Certificates created thereby and the mortgage loans evidenced thereby
         shall conform in all material respects to the respective descriptions
         thereof contained in the applicable Final Prospectus, except that no
         representation is made that the Conventional Certificates conform with
         the descriptions thereof (if any) contained in the Current Report.

                 (u)      Any certificate signed by an officer of the Company
         or Capstead and delivered to you or to counsel for the Underwriters
         shall be deemed a representation and warranty by the Company or
         Capstead, respectively, to each Underwriter as to the matters covered
         thereby.

                 (v)      No consent, approval, authorization, order,
         registration or qualification of or with any court or governmental
         agency or body of the United States is required for the issue and sale
         of the Bonds, or the consummation by the Company of the other
         transactions





                                     --7--
<PAGE>   8
         contemplated by this Agreement, each Terms Agreement or the Indenture,
         except such consents, approvals, authorizations, registrations or
         qualifications as may be required under state securities or Blue Sky
         laws in connection with the purchase and distribution of the Bonds by
         the Underwriters or as have been obtained.

                 (w)      At the Closing Time of a Series, the Bonds of such
         Series shall have been rated in the highest rating category by at
         least two nationally recognized statistical rating organizations or in
         such lower rating categories as are acceptable to the Underwriters.

                 (x)      Any taxes, fees and other governmental charges in
         connection with the execution, delivery and issuance of this
         Agreement, the related Terms Agreement, the Indenture and the Bonds
         have been paid or will be paid at or prior to the Closing Time.

                 (y)      All of the information regarding the characteristics
         of the Mortgage Loans contained in the Registration Statement or
         furnished to you by the Company in writing or by electronic
         transmission is true and correct.

         SECTION 2.  Sale  and  Delivery  to  the  Underwriters; Closing.  The
several commitments of the Underwriters to purchase Bonds pursuant to any Terms
Agreement shall be deemed to have been made on the basis of the representations
and warranties herein contained and subject to the terms and conditions herein
set forth, the Company agrees to sell to each Underwriter, severally and not
jointly, and each Underwriter, severally and not jointly, agrees to purchase
from the Company, the respective original principal amounts of the Bonds set
forth in the applicable Terms Agreement opposite the name of such Underwriter,
plus any additional original principal amount of Bonds which such Underwriter
may be obligated to purchase pursuant to Section 10 hereof.

         Delivery of, and payment of the purchase price for, the Bonds shall be
made at the office of Andrews & Kurth L.L.P., 1717 Main Street, Suite 3700,
Dallas, Texas  75201, or at such other place as shall be agreed upon by you and
the Company, at 10:00 A.M. (Dallas time) on the date set forth in the
applicable Terms Agreement, or such other time as shall be agreed upon by you
and the Company (such time and date being referred to as the "Closing Time").
Payment shall be made in immediately available or next day funds as specified
in the Terms Agreement, payable to or upon the order of the Company, against
delivery to you for the respective accounts of the Underwriters of the Bonds to
be purchased by them.  Such Bonds shall be in such denominations and registered
in such names as you may request in writing at least two business days prior to
the Closing Time.  The Bonds will be made available for your examination in
Dallas, Texas not later than 10:00 A.M. on the Business Day prior to the
Closing Time.

         SECTION 3. Covenants  of  the  Company.  The Company covenants with
you, and with each Underwriter participating in the offering of the applicable
Series of Bonds, as follows:





                                     --8--
<PAGE>   9
                 (a)      Immediately following the execution of each Terms
         Agreement, the Company will prepare a Final Prospectus setting forth
         the principal amount of Bonds covered thereby and their terms not
         otherwise specified in the Indenture, the names of the Underwriters
         participating in the offering and the principal amount of Bonds which
         each severally has agreed to purchase, the names of any Underwriters
         acting as co-managers with you in connection with the offering, the
         price at which the Bonds are to be purchased by the Underwriters from
         the Company, and such other information as you and the Company deem
         appropriate in connection with the offering of the Bonds.  The Company
         will promptly transmit copies of the Final Prospectus to the
         Commission for filing pursuant to Rule 424 of the 1933 Act Regulations
         and will furnish to the Underwriters named therein as many copies of
         the Final Prospectus as you shall reasonably request.

                 (b)      The Company will cause any Computational Materials
         (as defined in Section 8 below) with respect to the Bonds that are
         delivered by you to the Company pursuant to Section 8 hereof to be
         filed with the Commission on a Current Report on Form 8-K (the
         "Current Report") pursuant to Rule 13a-11 under the 1934 Act not later
         than the Business Day immediately following the Business Day on which
         all such Computational Materials are delivered to counsel for the
         Company by you prior to 3:00 p.m. Dallas, Texas time, and will
         promptly advise you when such Current Report has been filed, provided
         that in any event the Company will cause the Computational Materials
         to be so filed not later than the date on which the related Final
         Prospectus is required to be so filed pursuant to Rule 424 under the
         1933 Act.  Such Current Report shall be incorporated by reference in
         such Final Prospectus and the related Registration Statement.
         Notwithstanding the two preceding sentences, the Company shall have no
         obligation to file any materials provided by you pursuant to Section 8
         ("Section 8 Materials") which, in the reasonable determination of the
         Company (a "Non-Filing Determination"), are not required to be filed
         pursuant to the Kidder Letter (as defined in Section 8 below), or
         which contain erroneous information or contain any untrue statement of
         a material fact or, when read in conjunction with the Final Prospectus
         and Prospectus Supplement, omit to state a material fact required to
         be stated therein or necessary to make the statements therein not
         misleading (it being understood, however, that the Company shall have
         no obligation to review or pass upon the accuracy or adequacy of, or
         to correct, any Computational Materials provided by you to the Company
         pursuant to Section 8 hereof); provided that, in the event of a
         Non-Filing Determination, the Company shall immediately notify you in
         writing of the reasons for such Non-Filing Determination; and,
         provided, further, that the Company shall file those Section 8
         Materials for which you have specifically confirmed in writing that
         the items giving rise to the Non-Filing Determination are complete and
         correct and that you are advising the Company to file such Section 8
         Materials.

                 (c)      The Company will notify you immediately, and in
         writing confirm the notice, (i) of the receipt of any comments from
         the Commission, (ii) of any request by the





                                     --9--
<PAGE>   10
         Commission for any amendment to the Registration Statement or any
         amendment or supplement to the Final Prospectus or for additional
         information, (iii) of the issuance by the Commission of any stop order
         suspending the effectiveness of the Registration Statement or the
         initiation of any proceedings for that purpose, (iv) of 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 threat of any proceeding for that purpose, and (v) of
         the happening of any event which makes untrue any statement of a
         material fact made in, or results in the omission of material
         information from, the Registration Statement or in any Final
         Prospectus then required to be distributed or which requires the
         making of a change in the Registration Statement or any such Final
         Prospectus in order to make any material statements therein, in the
         light of the circumstances under which they were made, not misleading.
         The Company will make every reasonable effort to prevent the issuance
         of any stop order and, if any stop order is issued, to obtain the
         lifting thereof at the earliest possible moment.

                 (d)      The Company will give you notice of its intention to
         file any amendment to the Registration Statement or any amendment or
         supplement to the Final Prospectus, whether pursuant to the 1934 Act,
         1933 Act or otherwise, and will not file any such amendment or
         supplement without furnishing a copy thereof to you and counsel for
         the Underwriters and obtaining your consent to such filing, which
         consent shall not be unreasonably withheld or delayed.

                 (e)      The Company will deliver to you, as soon as
         practicable, as many signed copies of the Registration Statement as
         originally filed and of each amendment thereto, with signed consents
         and exhibits filed therewith (including exhibits incorporated by
         reference therein and documents incorporated by reference in the Final
         Prospectus), and will also deliver to you such number of conformed
         copies of the Registration Statement as originally filed and of each
         amendment thereto (including consents and exhibits) as you may
         reasonably request.

                 (f)      The Company will furnish to each Underwriter, from
         time to time during the period when the Final Prospectus is required
         to be delivered under the 1933 Act, such number of copies of the Final
         Prospectus (as amended or supplemented), other than exhibits to the
         related Current Report, as it may reasonably request for the purposes
         contemplated by the 1933 Act or the 1934 Act.

                 (g)      If at any time when a prospectus relating to the
         Bonds is required to be delivered under the 1933 Act any event occurs
         as a result of which the applicable Final Prospectus as then amended
         or supplemented would include an untrue statement of a material fact,
         or omit to state any material fact necessary to make the statements
         therein, in the light of the circumstances under which they were made,
         not misleading, or if it is





                                     --10--
<PAGE>   11
         necessary at any time to amend such Final Prospectus to comply with
         the 1933 Act, the Company, subject to subparagraph (d) above, promptly
         will prepare and file with the Commission an amendment or supplement
         which will correct such statement or omission or an amendment which
         will effect such compliance; provided, however, that the Company will
         not be required to file any such amendment or supplement with respect
         to any Computational Materials incorporated by reference in the Final
         Prospectus other than any amendments or supplements of such
         Computational Materials that are furnished to the Company by the
         Underwriter pursuant to Section 8(g) hereof that the Company
         determines to file in accordance therewith.

                 (h)      The Company will endeavor, in cooperation with you
         and counsel for the Underwriters, to qualify the Bonds for offering
         and sale under the applicable securities and Blue Sky laws of such
         jurisdictions as you may reasonably designate, and will maintain such
         qualification 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 you and counsel for
         the Underwriters, to determine the eligibility of the Bonds for
         investment by institutional investors in such jurisdictions.  The
         Company will, at your request or the request of counsel for the
         Underwriters, 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.

                 (i)      The Company will make generally available to its
         security holders and will deliver to you as soon as practicable an
         earnings statement, conforming to the requirements of Section 11(a) of
         the 1933 Act, covering a period of at least twelve months beginning
         after the effective date of the Registration Statement.  Compliance
         with Rule 158 under the 1933 Act shall satisfy the requirements of
         this paragraph.

                 (j)      So long as any Bonds are outstanding, the Company
         will furnish to you (or cause to be furnished to you) as soon as
         practicable upon your written request:

                          (i)     copies of the annual reports and other items
                 required to be delivered to the Bondholders pursuant to the
                 Indenture;

                          (ii)  copies of any reports and financial statements
                 furnished to or filed with the Commission or any national
                 securities exchange by the Company; and





                                     --11--
<PAGE>   12
                          (iii)  information as to the outstanding principal
                 balances of the mortgage loans underlying the Conventional
                 Certificates, and, to the extent that such information has
                 been maintained in the ordinary course of business by the
                 Company, such other information as may reasonably be requested
                 by you which in your judgment is necessary or appropriate to
                 the maintenance of a secondary market in the Bonds.

                 (k)      So long as any Bonds of any Series underwritten by
         you are outstanding, Capstead will furnish to you within five days
         after they are available, upon your written request, copies of all
         reports filed by Capstead under the 1934 Act.

                 (l)      The Company, during the period when the Prospectus is
         required to be delivered under the 1933 Act, will file promptly all
         documents required to be filed with the Commission pursuant to Section
         13 or 14 of the 1934 Act; provided, however, that the Company will not
         be required to file any amendment or supplement to the Current Report
         incorporated by reference in the Prospectus other than any amendments
         or supplements thereto that are furnished to the Company by you
         pursuant to Section 8(g) hereof which the Company determines to file
         in accordance therewith.

                 (m)      The Company shall prepare and file with the
         Commission, within the period provided in the related Final
         Prospectus, its Current Report on Form 8-K which shall include such
         detailed information, schedules and reports (the "Detailed
         Description") regarding the Conventional Certificates and the mortgage
         loans underlying such Conventional Certificates relating to the Series
         of Bonds offered by such Final Prospectus (the "Mortgage Loans") as
         you may reasonably request.

                 (n)      During the period, if any, commencing on the date of
         the applicable Terms Agreement and expiring on the date specified in
         such Terms Agreement (the "Stand-Off Period"), neither the Company,
         Capstead nor the Partnership or any subsidiary thereof will, without

         and (iii) there shall not have come to your attention any fact that
         would cause you to believe that the Final Prospectus at the time it

         untrue statement of a material fact or omitted to state a material

                                     --13--

         necessary in order to make the statements therein, in light of the 
         circumstances existing at such time, not misleading.

                 (b)      At the applicable Closing Time you shall have
         received:

         (1)  An opinion, addressed to the Underwriters and dated the Closing
Time, of Andrews & Kurth L.L.P., counsel to the Company, in form and substance
reasonably satisfactory to you and counsel for the Underwriters, to the effect
that:
                          (i)  The Company has been duly incorporated and is
                 validly existing as a corporation in good standing under the
                 laws of the State of Delaware.

                 to own, lease and operate its properties and conduct its
                 business as described in the applicable Final Prospectus; and
                 the Company is qualified as a foreign corporation to  transact
                 business in the State of Texas and each other jurisdiction
                 where the nature of its assets requires such qualification.

                          (iii)  All the authorized, issued and outstanding
                 capital stock of the Company has been duly authorized and
                 validly issued and is fully paid and non-assessable, and is
                 owned of record by Capstead, to the knowledge of such counsel,
                 free and clear of any lien, security interest, encumbrance,
                 option, warrant, voting trust or similar arrangement.

                          (iv)  The Company is not in violation of its charter
                 or bylaws.  To the best of such counsel's knowledge, the
                 Company is not in default in the performance or observance of
                 any obligation, agreement, covenant or condition contained in
                 any material contract, indenture, mortgage, loan agreement,
                 note, lease or other instrument to which it is a party or by
                 which it or its properties may be bound.

                          (v)  To the best of such counsel's knowledge, the
                 Company owns or possesses or has obtained all material
                 governmental licenses, permits, consents, orders, approvals
                 and other authorizations necessary to lease or own, as the
                 case may be, and to operate, its properties and to carry on
                 its businesses as presently conducted; and, to the best of
                 such counsel's knowledge, the Company has conducted and is
                 conducting its businesses so as to comply in all material
                 respects with all applicable laws.

                          (vi)  There is no action, suit or proceeding before
                 or by any court or governmental agency or body, domestic or
                 foreign, now pending, or, to the best of





                                     --14--
<PAGE>   15
                 such counsel's knowledge, threatened against the Company which
                 could reasonably be expected to interfere with or adversely
                 affect the consummation of the transactions contemplated
                 herein.

                          (vii)  The execution and delivery of this Agreement,
                 the applicable Terms Agreement and the Indenture (including
                 the applicable Series Supplement), the incurrence of the
                 obligations herein and therein set forth and the consummation
                 of the transactions contemplated herein and therein have been
                 duly authorized by the Company, by all necessary action; this
                 Agreement and the applicable Terms Agreement have been duly
                 authorized, executed and delivered by the Company; and the
                 Indenture (including the applicable Series Supplement) has
                 been duly authorized, executed and delivered by the Company
                 and  constitutes  a  legal,  valid  and  binding agreement of
                 the Company, enforceable in accordance with its terms,
                 subject, as to enforceability of remedies, to applicable
                 bankruptcy, insolvency, reorganization or other laws affecting
                 creditors' rights generally and to general principles of
                 equity and equitable remedies (regardless of whether the
                 enforceability of such remedies is considered in a proceeding
                 at law or in equity).

                          (viii)  Neither the execution and delivery of this
                 Agreement, the applicable Terms Agreement or the Indenture,
                 the incurrence of the obligations herein or therein set forth,
                 nor the consummation of the transactions contemplated herein
                 or therein, to the best of such counsel's knowledge, will
                 conflict with or constitute a breach of, or default under, or
                 result in the creation or imposition of any Lien upon any
                 property or assets of the Company pursuant to, any material
                 contract, indenture, mortgage, loan agreement, note, lease or
                 other instrument to which the Company is a party or by which
                 it may be bound, or to which any of its assets is subject
                 (other than the Lien created by the Indenture) which
                 separately or in the aggregate are material, nor will any such
                 action result in any violation of the provisions of the
                 charter or bylaws of the Company or, to the best of such
                 counsel's knowledge, of any law, administrative regulation or
                 administrative or court decree.

                          (ix)  No filing or, registration with, notice to or
                 consent, approval, authorization or order or other action of,
                 any court or governmental authority or agency, is required for
                 the consummation by the Company of the transactions
                 contemplated by this Agreement or the applicable Terms
                 Agreement, except such as have been obtained and except such
                 as may be required under state securities or Blue Sky laws in
                 connection with the distribution of the Bonds referred to in
                 such Terms Agreement by the Underwriters.

                          (x)  The issuance of the Bonds to be underwritten at
                 such time pursuant to this Agreement has been duly authorized
                 by the Company and such Bonds have been





                                     --15--
<PAGE>   16
                 duly executed and delivered by the Company and, assuming due
                 authorization, execution and delivery of the Indenture by the
                 Trustee, when authenticated by the Trustee in accordance with
                 the terms of the Indenture and delivered to and paid for by
                 the Underwriters pursuant to the applicable Terms Agreement,
                 will constitute legal, valid and binding non-recourse
                 obligations of the Company, enforceable in accordance with
                 their terms, subject, as to enforceability of remedies, to
                 applicable bankruptcy, insolvency, reorganization or other
                 laws affecting creditors' rights generally and to general
                 principles of equity and equitable remedies (regardless of
                 whether the enforceability of such remedies is considered in a
                 proceeding at law or in equity), and the Bonds are entitled to
                 the benefits and security provided by the Indenture.

                          (xi)  The Bonds to be underwritten at such time
                 pursuant to this Agreement and the Indenture conform in all
                 material respects to the respective descriptions thereof
                 contained in the applicable Final Prospectus (excluding any
                 descriptions thereof in the Current Report, as to which no
                 opinion need be rendered).

                          (xii)  At the Closing Time, the Company had corporate
                 power and authority to assign, pledge and deliver the Initial
                 Collateral to the Trustee under the Indenture, and had duly
                 authorized such assignment, pledge and delivery to the Trustee
                 by all necessary corporate action.

                          (xiii)  Immediately prior to the grant to the Trustee
                 of the Conventional Certificates securing the Bonds to be
                 underwritten at such time pursuant to this Agreement, the
                 Company owned such Conventional Certificates, free and clear
                 of any Lien, except the lien of the Indenture; each such
                 Conventional Certificate has been duly and validly assigned,
                 pledged and delivered by the Company to the Trustee or its
                 nominee under the Indenture; the Indenture, together with such
                 assignment, pledge and delivery of each such Conventional
                 Certificate, the filing of a UCC-1 financing statement with
                 respect to the Conventional Certificates with the office of
                 the Secretary of State of the State of Texas and in such other
                 jurisdictions, if any, as such counsel deems appropriate, and
                 the possession by the Trustee, or its nominee, of the
                 Conventional Certificates not represented by book-entry
                 accounts and of the other assets comprising the Initial
                 Collateral, create as security for such Bonds a valid and
                 perfected security interest in the Trust Estate as security
                 for the repayment of such Bonds free and clear of any prior
                 Lien; a UCC-1 financing statement with respect to the security
                 interest created by the Indenture has been filed in the office
                 of the Secretary of State of the State of Texas and in such
                 other offices, if any, as such counsel deems appropriate; no
                 other recordings or filings in any jurisdiction are necessary
                 to perfect the security interest of the Trustee in the Initial
                 Collateral as





                                     --16--
<PAGE>   17
                 against any third party, and no further action is required to
                 create, attach or perfect such security interest except that:

                 (A)      appropriate continuation statements with respect to
                          the UCC-1 financing statements referred to above must
                          be filed within six months prior to the expiration of
                          each consecutive five-year period commencing upon the
                          date of initial filing, and

                 (B)      with respect to items of Initial Collateral and the
                          distributions thereof, a perfected security interest
                          in which is perfected by delivery of possession,
                          possession of such items must be maintained by the
                          Trustee or its bailee (other than an affiliate of the
                          Company).

                          (xiv)  The Registration Statement is effective under
                 the 1933 Act, and, to the best of such counsel's knowledge, no
                 stop order suspending the effectiveness of the Registration
                 Statement has been issued under the 1933 Act and no
                 proceedings for that purpose have been instituted or
                 threatened by the Commission.  The Indenture has been duly
                 qualified under the 1939 Act.

                          (xv)  The Registration Statement and the applicable
                 Final Prospectus, and each amendment or supplement thereto
                 (other than the financial statements, schedules, notes
                 thereto, and the financial and statistical data included
                 therein and any documents incorporated by reference in the
                 Registration Statement and the applicable Final Prospectus,
                 including without limitation the Current Report, in each case
                 as to which no opinion need be rendered), as of their
                 respective effective or issue dates, complied as to form in
                 all material respects with the requirements of the 1933 Act,
                 the 1933 Act Regulations, the 1939 Act and the 1939 Act
                 Regulations; and each document, if any, filed pursuant to the
                 1934 Act (other than the financial statements, schedules,
                 notes thereto, and the financial and statistical data included
                 therein and any documents incorporated by reference in the
                 Registration Statement and the applicable Final Prospectus,
                 including without limitation the Current Report, in each case
                 as to which no opinion need be rendered) and incorporated by
                 reference in the applicable Final Prospectus, complied when so
                 filed as to form in all material respects with the 1934 Act
                 and the rules and regulations thereunder.

                          (xvi)  The statements in the applicable Final
                 Prospectus under the caption "Certain Federal Income Tax
                 Consequences", to the extent they constitute matters of law or
                 legal conclusions, have been prepared or reviewed by such
                 counsel and correctly represent the opinion of such counsel;
                 the descriptions in such Final Prospectus of statutes, legal
                 and governmental proceedings and contracts and other documents
                 are accurate and fairly present the information required to be
                 shown.





                                     --17--
<PAGE>   18
                          (xvii)  To the best of such counsel's knowledge,
                 there are no legal or governmental proceedings pending or
                 threatened which are required to be disclosed therein, nor any
                 contracts or documents of a character required to be described
                 or referred to in the Registration Statement or to be filed as
                 exhibits thereto other than those described or referred to
                 therein or filed as exhibits thereto (other than financial
                 statements, schedules, and notes thereto and the financial and
                 statistical data included therein and the other documents, if
                 any, incorporated by reference therein, as to which no opinion
                 need be rendered).

                          (xviii)  The Company is not, and will not as a result
                 of the offer and sale of the Bonds as contemplated in this
                 Agreement and any applicable Terms Agreement, become an
                 "investment company" or under the "control" of an "investment
                 company" as such terms are defined in the Investment Company
                 Act which would be required to register under the Investment
                 Company Act.

                          (xix)  Nothing has come to the attention of such
                 counsel that would lead them to believe that the Registration
                 Statement or any amendment thereto (other than the financial
                 statements, schedules, notes thereto and the financial and
                 statistical data included therein and any documents
                 incorporated by reference therein including without limitation
                 the Current Report related thereto, in each case as to which
                 no opinion need be rendered), at their respective effective
                 dates, contained an untrue statement of a material fact or
                 omitted to state a material fact required to be stated therein
                 or necessary to make the statements therein not misleading, or
                 that the Final Prospectus or any amendment or supplement
                 thereto (other than the Current Report related thereto, in
                 each case as to which no opinion need be rendered), at their
                 respective issue dates or, as amended or supplemented (except
                 as aforesaid), at Closing Time, contained an untrue statement
                 of a material fact or omitted to state a material fact
                 necessary in order to make the statements therein, in the
                 light of the circumstances under which they were made, not
                 misleading.

                          (xx)  The Bonds to be underwritten at such time
                 pursuant to this Agreement, or the Classes thereof as are
                 identified in such opinion for these purposes, will be
                 "mortgage related securities", as defined in Section 3(a)(41)
                 of the 1934 Act, so long as such Bonds or the identified
                 Classes are rated in one of the two highest rating categories
                 by at least one nationally recognized statistical rating
                 organization.

         (2)     The opinion, addressed to the Underwriters  and dated the
Closing Time, of counsel to Capstead in form and substance reasonably
satisfactory to you and counsel for the Underwriters, to the effect that:

                 agreement, covenant or condition contained in any material
                 contract, indenture, mortgage, loan agreement, note, lease or
                 other instrument to which it is a party or by which it or its
                 properties may be bound.

                          (iii)  There is no action, suit or proceeding before
                 or by any court or governmental agency or body, domestic or
                 foreign, now pending, or, to the best of such counsel's
                 knowledge, against Capstead which could reasonably be expected
                 to interfere with or adversely affect the consummation of the
                 transactions contemplated herein.

                          (iv)  The execution and delivery of this Agreement
                 and the applicable Terms Agreement, the incurrence of the
                 obligations herein and therein set forth and the consummation

                 been duly authorized, executed and delivered by Capstead.

                          (v)  No filing or registration with, notice to or
                 consent, approval, authorization or order or other action of,

                 the consummation by Capstead of the transactions contemplated
                 by this Agreement or the applicable Terms Agreement, except
                 such as have been obtained and except such as may be required
                 under state securities or Blue Sky laws in connection with the
                 distribution of the Bonds to be underwritten at such time
                 pursuant to this Agreement by the Underwriters.

                 (c)      At the Closing Time you shall have received the
         opinion of Andrews & Kurth L.L.P., addressed to the Underwriters and

         Closing Time.

                 (f)      The Company and you shall have received from Deloitte

                          (i)  The Trustee is duly incorporated, validly
                 existing and in good standing as a national banking

         Prospectus and opinions of counsel with respect to such policies) as
         they may reasonably require for the purpose of enabling them to pass
         upon the Registration Statement, the applicable Final Prospectus, the
         issuance and sale of the Bonds then to be underwritten pursuant to
         this Agreement as contemplated in the applicable Terms Agreement and

         If any condition in this Section shall not have been fulfilled when
and as required to be fulfilled, this Agreement and the applicable Terms
Agreement may be terminated by you by notice to the Company at any time at or
prior to the Closing Time, and such termination shall be without liability of
any party to any other party except as provided in Section 4.

         SECTION 6.  Indemnification.  (a)  The Company and Capstead, jointly
and severally, agree to indemnify and hold harmless each Underwriter and each
person, if any, who controls any Underwriter within the meaning of Section 15
of the 1933 Act as follows:

                          (i)  against any and all loss, liability, claim,
                 damage and expense whatsoever, as incurred, arising out of any
                 untrue statement or alleged untrue statement of a material
                 fact contained in the Registration Statement (or any amendment
                 thereto), or the omission or alleged omission therefrom of a
                 material fact required to be stated therein or necessary to
                 make the statements therein not misleading or arising out of
                 any untrue statement or alleged untrue statement of a material
                 fact contained in any preliminary prospectus, preliminary
                 prospectus supplement or the Final Prospectus (or any
                 amendment or supplement thereto) or the omission or alleged
                 omission therefrom of a material fact necessary in order to
                 make the statements therein in the





                                     --21--
<PAGE>   22
                 light of the circumstances under which they were made not
                 misleading; provided, however, that (A) the Company shall not
                 be liable in any such case if such untrue statement or
                 omission or such alleged untrue statement or omission was made
                 (1) in reliance upon and in conformity with written
                 information furnished to the Company by any Underwriter
                 through you expressly for use in the Registration Statement
                 (or any amendment thereto) or in any preliminary prospectus,
                 preliminary prospectus supplement or each Final Prospectus (or
                 any amendment or supplement thereto) or (2) in any Current
                 Report or any amendment or supplement thereof, except to the
                 extent that any untrue statement or alleged untrue statement
                 therein results (or is alleged to have resulted) directly from
                 an error (a "Mortgage Collateral Error") in the information
                 concerning the characteristics of the Mortgage Loans furnished
                 by the Company to you in writing or by electronic transmission
                 that was used in the preparation of either (x) any
                 Computational Materials (or amendments or supplements thereof)
                 included in such Current Report (or amendment or supplement
                 thereof) or (y) any written or electronic materials furnished
                 to prospective investors on which the Computational Materials
                 (or amendments or supplements thereof) were based; (B) such
                 indemnity with respect to any Corrected Statement (as defined
                 below) in such Final Prospectus (or supplement thereto) shall
                 not inure to the benefit of any Underwriter (or any person
                 controlling any Underwriter) from whom the person asserting
                 any loss, claim, damage or liability purchased the Bonds that
                 are the subject thereof if such person did not receive a copy
                 of a supplement to such Final Prospectus at or prior to the
                 confirmation of the sale of such Bonds and the untrue
                 statement or admission of a material fact contained in such
                 Final Prospectus (or supplement thereto) was corrected (a
                 "Corrected Statement") in such other supplement and such
                 supplement was furnished by the Company to you prior to the
                 delivery of such confirmation; and (C) such indemnity with
                 respect to any Mortgage Collateral Error shall not inure to
                 the benefit of any Underwriter (or any person controlling the
                 Underwriter) from whom the person asserting any loss, claim,
                 damage or liability received any Computational Materials (or
                 any written or electronic materials on which the Computational
                 Materials are based) that were prepared on the basis of such
                 Mortgage Collateral Error, if, prior to the time of
                 confirmation of the sale of the applicable Bonds to such
                 person, the Company notified you in writing of the Mortgage
                 Collateral Error or provided in written or electronic form
                 information superseding or correcting such Mortgage Collateral
                 Error (in any such case a "Corrected Mortgage Collateral
                 Error"), and such Underwriter failed to notify such person
                 thereof or to deliver to such person corrected Computational
                 Materials (or underlying written or electronic materials
                 relating thereto);

                          (ii)  against any and all loss, liability, claim,
                 damage and expense whatsoever, as incurred, to the extent of
                 the aggregate amount paid in settlement of any litigation,
                 investigation or proceeding by any governmental agency or
                 body, commenced or





                                     --22--
<PAGE>   23
                 threatened, or of any claim whatsoever based, in each case,
                 upon any such untrue statement or omission, or any such
                 alleged untrue statement or omission, if such settlement is
                 effected with the written consent of the Company;

                          (iii)  against any and all expense whatsoever, as
                 incurred (including the reasonable fees and disbursements of
                 counsel chosen by you) reasonably incurred in investigating,
                 preparing or defending against any litigation, or
                 investigation or proceeding by any governmental agency or
                 body, commenced or threatened or any claim whatsoever based
                 upon any such untrue statement or omission, or any such
                 alleged untrue statement or omission, to the extent that any
                 such expense is not paid under (i) or (ii) above;

                 (b)      Each Underwriter severally agrees to indemnify and
         hold harmless the Company, its directors, each of its officers who
         signed the Registration Statement, Capstead and each person, if any,
         who controls the Company or Capstead within the meaning of Section 15
         of the 1933 Act and the officers and directors of any such person
         against any and all loss, liability, claim, damage and expense
         described in the indemnity contained in subsection (a) of this
         Section, but only with respect to untrue statements or omissions, or
         alleged untrue statements or omissions, made in the Registration
         Statement (or any amendment thereto) or any preliminary prospectus,
         preliminary prospectus supplement or the Final Prospectus (or any
         amendment or supplement thereto) in reliance upon and in conformity
         with (i) written information furnished to the Company by such
         Underwriter expressly for use in the Registration Statement (or any
         amendment thereto) or in any preliminary prospectus, preliminary
         prospectus supplement or each Final Prospectus (or any amendment or
         supplement thereto) or (ii) any Computational Materials (or amendments
         or supplements thereof) furnished to the Company by such Underwriter
         pursuant to Section 8 hereof and incorporated by reference in such
         Registration Statement or the related Final Prospectus or any
         amendment or supplement thereto (except that no such indemnity shall
         be available for any losses, claims, damages or liabilities, or
         actions in respect thereof, resulting from any Mortgage Collateral
         Error, other than a Corrected Mortgage Collateral Error).

                 (c)      Each indemnified party shall give prompt notice to
         each indemnifying party of any action commenced against it in respect
         of which indemnity may be sought hereunder but failure to so notify an
         indemnifying party shall not relieve it from any liability which it
         may have otherwise than on account of this indemnity agreement.  An
         indemnifying party may participate at its own expense in the defense
         of such action.  In no event shall the indemnifying parties be liable
         for the fees and expenses of more than one counsel in connection with
         any one action or separate but similar and related actions in the same
         jurisdiction arising out of the same general allegations or similar
         circumstances.

                 (d)      The indemnity agreement provided by this Section 6
         shall be in addition to any liability the Company and the Underwriters
         shall otherwise have.

         SECTION 7.  Contribution.  In order to provide for just and equitable
contribution in circumstances in which the indemnity agreement provided for in
Section 6 is for any reason held to be unavailable to or insufficient to hold
harmless the indemnified parties although applicable in accordance with its
terms, the Company and Capstead, on the one hand, and the Underwriters on the
other, shall:

                 (a) in the case of any losses, claims, damages and liabilities
         (or actions in respect thereof) relating to a class or classes of any
         Series of Bonds (a "Class" or "Classes," as the case may be) which do
         not arise out of or are not based upon any untrue statement or
         omission of a material fact in any Computational Materials (or any
         amendments or supplements thereof), contribute to the aggregate
         losses, liabilities, claims, damages and expenses of the nature
         contemplated by said indemnity agreement incurred in respect of any
         Class or Classes underwritten pursuant to this Agreement by the
         Company or  Capstead and the Underwriter of such Class or Classes, as
         incurred, in such proportions that the Underwriter of such Class or
         Classes is responsible for that portion represented by the percentage
         that the difference between the proceeds to the Company appearing on
         the cover page of the applicable Final Prospectus and the total of all
         proceeds received by such Underwriter from the sale of all Bonds
         underwritten by it (the "Underwriting Discount") bears to the total
         proceeds received by such Underwriter from such Bonds, and the Company
         and Capstead are responsible for the balance;

                 (b) in the case of any losses, claims, damages and liabilities
         (or actions in respect thereof) which arise out of or are based upon
         any untrue statement or omission of a material fact in any
         Computational Materials (or any amendments or supplements thereof),
         contribute to the aggregate losses, liabilities, claims, damages and
         expenses of the nature contemplated by said indemnity agreement
         incurred in respect of any Class or Classes underwritten pursuant to
         this Agreement by the Company or Capstead, and the Underwriter of such
         Class or Classes, as incurred, in such proportion as is appropriate to
         reflect the relative fault of the Company and Capstead on the one hand
         and such Underwriter on the other hand in connection with the
         statements or omissions which resulted in such losses, liabilities,
         claims, damages and expenses (or actions in respect thereof) as well
         as any other relevant equitable considerations; provided that in no
         event shall such Underwriter be responsible for an amount greater than
         the excess, if any, of (i) the total proceeds received by such
         Underwriter in the sale of all Bonds underwritten by it (taking into

provided, however, that 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, each person, if any, who
controls an Underwriter within the meaning of Section 15 of the 1933 Act shall
have the same rights to contribution as such Underwriter and each director of
the Company, each officer of the Company and Capstead who signed the
Registration Statement, and each person, if any, who controls the Company or
Capstead within the meaning of Section 15 of the 1933 Act and the officers and
directors of any such person shall have the same rights to contribution as the
Company or Capstead.

                 SECTION 8.  Computational Materials.  (a) As soon as
practicable and in no event later than 3:00 p.m.  Dallas, Texas time three
Business Days before the date on which the Final Prospectus relating to the

regarding the Class or Classes being underwritten by you which constitute

20, 1994 issued by the Division of Corporation Finance of the Commission to
Kidder, Peabody Acceptance Corporation I, Kidder, Peabody & Co. Incorporated,
and Kidder Structured Asset Corporation (the "Kidder Letter"), and the filing
of which material is a condition of the relief granted in such letter (such
materials being the "Computational Materials").  Each delivery of Computational
Materials to the Company pursuant to this paragraph (a) shall be effected by
delivering four copies of such materials to counsel for the Company at Andrews
& Kurth L.L.P., 4400 Thanksgiving Tower, Dallas, Texas 75201, or such other
address specified by such counsel to you in writing, and one copy of such
materials to the Company.

                 (b)      You represent and warrant to and agree with the
         Company, as of the date of the related Terms Agreement and as of the
         Closing Date, that:

                          (i)     the Computational Materials furnished to the
                 Company pursuant to Section 8(a) constitute (either in
                 original, aggregated or consolidated form) all of the
                 materials furnished to prospective investors by the
                 Underwriters prior to the time of delivery thereof to the
                 Company that are required to be filed with the Commission with
                 respect to the related Bonds in accordance with the Kidder
                 Letter, and such Computational Materials comply with the
                 requirements of the Kidder Letter; and

                          (ii)    on the date any such Computational Materials
                 with respect to such Bonds (or any written or electronic
                 materials furnished to prospective investors on which the
                 Computational Materials are based) were last furnished to each
                 prospective investor and on the date of delivery thereof to
                 the Company pursuant to Section 8(a) and on the related
                 Closing Date, such Computational Materials (or materials) did
                 not and will not include any untrue statement of a material
                 fact or, when read in





                                     --25--
<PAGE>   26
                 conjunction with the Final Prospectus and Prospectus
                 Supplement, omit to state a material fact required to be
                 stated therein or necessary to make the statements therein not
                 misleading.

Notwithstanding the foregoing, you make no representation or warranty as to
whether any Computational Materials (or any written or electronic materials on
which the Computational Materials are based) included or will include any
untrue statement resulting directly from any Mortgage Collateral Error (except
any Corrected Mortgage Collateral Error, with respect to materials prepared
after the receipt by you from the Company of notice of such Corrected Mortgage
Collateral Error or materials superseding or correcting such Corrected Mortgage
Collateral Error).

         (c)     You acknowledge and agree that the Company has not authorized
and will not authorize the distribution of any Computational Materials to any
prospective investor, and agree that any Computational Materials with respect
to any Series of Bonds furnished to prospective investors from and after the
date hereof shall include a disclaimer in form reasonably satisfactory to the
Company.  You agree that you will not represent to investors that any
Computational Materials were prepared or disseminated on behalf of the Company.
This disclaimer shall not alter the rights or obligations of the parties hereto
pursuant to Sections 6 and 7 hereof.

         (d)     If, at any time when a prospectus relating to the Bonds of a
Series is required to be delivered under the 1933 Act, it shall be necessary to
amend or supplement the related Final Prospectus as a result of an untrue
statement of a material fact contained in any Computational Materials provided
by you pursuant to this Section 8 or the omission to state therein a material
fact required, when considered in conjunction with the Final Prospectus and
Prospectus Supplement, to be stated therein or necessary to make the statements
therein, when read in conjunction with the Final Prospectus and Prospectus
Supplement, not misleading, or if it shall be necessary to amend or supplement
any Current Report to comply with the 1933 Act or the rules thereunder, you
promptly will prepare and furnish to the Company for filing with the Commission
an amendment or supplement which will correct such statement or omission or an
amendment which will effect such compliance.  You represent and warrant to the
Company, as of the date of delivery of such amendment or supplement to the
Company, that such amendment or supplement will not include any untrue
statement of a material fact or, when read in conjunction with the Final
Prospectus and Prospectus Supplement, omit to state a material fact required to
be stated therein or necessary to make the statements therein not misleading.
The Company shall have no obligation to file such amendment or supplement if
the Company determines that (i) such amendment or supplement contains any
untrue statement of a material fact or, when read in conjunction with the Final
Prospectus and Prospectus Supplement, omits to state a material fact required
to be stated therein or necessary to make the statements therein not misleading
(it being understood, however, that the Company shall have no obligation to
review or pass upon the accuracy or adequacy of, or to correct, any such
amendment or supplement provided by the Underwriter to the Company pursuant to
this paragraph (d)) or (ii) such filing is not required under the Act; provided
that, in the event the





                                     --26--
<PAGE>   27
Company makes such a determination, it shall immediately notify you in writing
of the reasons for such determination; and, provided, further, that it shall
file such amendment or supplement if you specifically confirm in writing to the
Company that (A) such amendment or supplement does not contain any untrue
statement of a material fact or, when read in conjunction with the Final
Prospectus and Prospectus Supplement, omit to state a material fact required to
be stated therein or necessary to make the statements therein not misleading
and (B) you are advising the Company to file such amendment or supplement.

         (e)  You will cooperate with, and provide any information necessary to
the Independent Accountants so that they may complete and deliver their
agreed-upon procedures letter described in Section 5(f) hereof in a timely
manner so that such letter may be delivered to the Company by not later than
5:00 p.m. New York time, on the Business Day before the date on which the
Current Report described in Section 3(b) is required to be filed with the
Commission.

         SECTION 9.  Representations, Warranties, and Agreements to Survive
Delivery.  All representations, warranties and agreements contained in this
Agreement, or contained in certificates of officers of the Company or Capstead
submitted pursuant hereto or as contemplated hereby, shall remain operative and
in full force and effect, regardless of any investigation made by or on behalf
of the Company or Capstead or a controlling person thereof, and shall survive
delivery of any Bonds to the Underwriters.

         SECTION 10.  Termination of Agreement.  (a)  This Agreement may be
terminated for any reason at any time by either the Company or you upon the
giving of thirty days' written notice of such termination to the other party
hereto; provided, however, that if a Terms Agreement has been entered into but
the applicable Closing Time has not occurred, this Agreement shall not be
terminated pursuant to this Section 10(a) prior to such Closing Time.

         (b)  You may terminate this Agreement or such Terms Agreement, by
notice to the Company, at any time at or prior to the Closing Time, (i) if
there has been, since the respective dates as of which information is given in
the Registration Statement or the applicable Final Prospectus, any material
adverse change in the condition, financial or otherwise, earnings, business
affairs, regulatory situation or business prospects of the Company, Capstead or
the Partnership, whether or not arising in the ordinary course of business,
(ii) if there shall have occurred any material adverse change in the financial
markets of the United States or any outbreak or escalation of hostilities or
other national or international calamity or crisis the effect of which is such
as to make it, in your judgment, impracticable to market the Bonds or enforce
contracts for the sale of the Bonds, or (iii) if trading in any securities of
the Company has been suspended by the Commission or a national securities
exchange, or if trading generally on either the American Stock Exchange or the
New York Stock Exchange shall have been suspended, or minimum or maximum prices
for trading have been fixed, or maximum ranges for prices for securities have
been required, by either of said exchanges or by order of the Commission or any
other governmental authority, or if a banking moratorium shall have





                                     --27--
<PAGE>   28
been declared by either Federal or New York authorities, or (iv) if the rating
assigned by any nationally recognized securities rating agency requested to
rate any specific debt securities of the Company as of the date of any
applicable Terms Agreement shall have been lowered since that date or if any
such rating agency shall have publicly announced that it has under surveillance
or review, with possible negative implications, its requested rating of such
debt securities of the Company, or (v) if there shall have come to your
attention any facts that would cause you to believe that the applicable Final
Prospectus, at the time it was required to be delivered to a purchaser of the
Bonds offered thereby, contained an untrue statement of a material fact or
omitted to state a material fact necessary in order to make the statements
therein, in light of the circumstances existing at the time of such delivery,
not misleading.

         (c)     In the event of any such termination, (i) the covenants set
forth in Section 3 with respect to any offering of Bonds shall remain in effect
so long as any Underwriter owns any such Bonds purchased from the Company
pursuant to the applicable Terms Agreement and (ii) the covenant set forth in
Section 3(i), the provisions of Section 4, the indemnity agreement set forth in
Section 6, the contribution provisions set forth in Section 7, and the
provisions of Sections 8, 9 and 14 shall remain in effect.

         SECTION 11.  Default by One or More of the Underwriters.  If one or
more of the Underwriters shall fail at the Closing Time to purchase the Bonds
which it or they are obligated to purchase hereunder and under the applicable
Terms Agreement (the "Defaulted Bonds"), you shall have the right, within 24
hours thereafter, to make arrangements for one or more of the non-defaulting
Underwriters, or any other underwriters, to purchase all, but not less than
all, of the Defaulted Bonds in such amounts as may be agreed upon and upon the
terms herein set forth and under the applicable Terms Agreement.  If, however,
you have not completed such arrangements within such 24-hour period, then:

                 (a)      if the aggregate original principal amount of
         Defaulted Bonds does not exceed 10% of the aggregate original
         principal amount of the Bonds to be purchased pursuant to such Terms
         Agreement, the non-defaulting Underwriters named in such Terms
         Agreement shall be obligated to purchase the full amount thereof in
         the proportions that their respective underwriting obligations
         thereunder bear to the underwriting obligations of all non-defaulting
         Underwriters; and

                 (b)      if the aggregate original principal amount of
         Defaulted Bonds exceeds 10% of the aggregate original principal amount
         of the Bonds to be purchased pursuant to such Terms Agreement, the
         applicable Terms Agreement shall terminate without any liability on
         the part of any non-defaulting Underwriter.

         No action taken pursuant to this Section 11 and nothing in this
Agreement shall relieve any defaulting Underwriter from liability in respect of
its default.

<PAGE>   29
         In the event of any such default which does not result in a
termination of this Agreement or such applicable Terms Agreement, either you or
the Company shall have the right to postpone the Closing Time for a period of
time not exceeding seven days in order to effect any required changes in the
Registration Statement or in any other documents or arrangements.

         SECTION 12.  Notices.  All notices and other communications hereunder
shall be in writing and shall be deemed to have been duly given if mailed or
transmitted by any standard form of written telecommunication.  Notices to the

and be binding upon you, the Company and Capstead, and any Terms Agreement
shall inure to the benefit of and be binding upon the Company and Capstead and
any Underwriter who becomes a party to such Terms Agreement, and their
respective successors.  Nothing expressed or mentioned in this Agreement or any
Terms Agreement is intended or shall be construed to give any person, firm or
corporation, other than the parties hereto and their respective successors and
the controlling persons and officers and directors referred to in Sections 6
and 7 and their heirs and legal representatives, any legal or equitable right,
remedy or claim under or in respect of this Agreement or any Terms Agreement or

Agreement and all conditions and provisions hereof are intended to be for the
sole and exclusive benefit of the parties hereto and thereto and their
respective successors, and said controlling persons and officers and directors

be deemed to be a successor by reason merely of such purchase.

AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE
STATE OF NEW YORK.  SPECIFIED TIMES OF DAY REFER TO NEW YORK CITY TIME.

authorized by the Board of Directors, be issued in one or more Series, each of
which Series may consist of only one Class of Bonds or may be divided into two
or more Classes, and shall be designated generally as the "Collateralized
Mortgage Obligations" of the Issuer, with such further particular designations
added or incorporated in such title for the Bonds of any particular Series or
Class as the Board of Directors may determine.  Each Series shall include at
least one Class of Bonds which are not Compound Interest Bonds and may, but
need not, include one or more Classes of Compound Interest Bonds.

         If a Series of Bonds includes more than one Class, the Classes of
Bonds of such Series shall have such Stated Maturities as shall be specified in
the related Series Supplement.  Subject to the provisions of Section 3.1,
Section 5.19 and Section 8.2(d), the principal of each Bond shall be payable in
installments ending no later than the Stated Maturity of the final installment
of the principal thereof unless the unpaid principal of such Bond becomes due
and payable at an earlier date by declaration of acceleration, redemption or
otherwise.

         All payments of principal on the Bonds of a Series shall be applied on
each Payment Date prior to the occurrence of an Event of Default among the
Classes of such Bonds in accordance with the order of priority of payment set
out, and otherwise upon the terms specified in, the related Series Supplement.
Except to the extent specified in the related Series Supplement for a Series of
Bonds, payments of principal on each Class of Bonds, other than a Class of
Bonds subject to redemption at the request of a Holder, shall be made pro rata
among all Outstanding Bonds of such Class, without preference or priority of
any kind.

         The aggregate amount of principal of and interest on the Bonds of a
Series due and payable on each Payment Date for such Series shall be equal to
the Debt Service Requirement for such Series for such Payment Date.  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 as if each year
consisted of twelve months of thirty days each.

         Interest shall accrue on the Imputed Principal Balance of each
Outstanding Bond of a Series at the Bond Interest Rate relative thereto over
the related Interest Accrual Period and (other than interest accrued on any
Compound Interest Bonds of such Series, which shall be payable as described
below) shall be payable on each Interest Payment Date for such Series in an
amount equal to the lesser of (a) Available Funds on such Interest Payment
Date, after payment of all amounts





                                      -30-
<PAGE>   33
payable in priority to such interest payment, as determined pursuant to the
related Series Supplement, and (b) Accrued Bond Interest for such Interest
Payment Date.

         Interest at the applicable Bond Interest Rate shall accrue on the
Imputed Principal Balance of each Outstanding Compound Interest Bond of a
Series from the Accrual Date for such Series, but none of such accrued interest
shall be payable until the Initial Interest Payment Date for such Compound
Interest Bond (or the first Interest Payment Date thereafter if the Debt
Service Requirement for such Initial Interest Payment Date is exactly equal to
the aggregate amount of principal of and interest on all other Classes of Bonds
of such Series which is payable on such Initial Interest Payment Date).  On
each Interest Payment Date prior to the Initial Interest Payment Date for a
Compound Interest Bond, Accrued Bond Interest on such Bond during the related
Interest Accrual Period shall be added to the Current Principal Amount of such
Bond and shall thereafter accrue interest.  Except as otherwise specified in
the related Series Supplement, on the Initial Interest Payment Date for the
Compound Interest Bonds of a Series, Accrued Bond Interest on such Bonds for
the related Interest Accrual Period shall be payable in an amount not in excess
of the difference between (a) the Debt Service Requirement on the related
Series for such Initial Interest Payment Date and (b) the aggregate amount of
principal of and interest on all other Bonds of the related Series required to
be paid on such date.  The portion, if any, of such interest which is not paid
on such Initial Interest Payment Date shall be added to the principal of such
Compound Interest Bonds on such Initial Interest Payment Date and shall
thereafter accrue interest in the manner set forth above.  On each Interest
Payment Date after the Initial Interest Payment Date for a Class of Compound
Interest Bonds Accrued Bond Interest on the Class Imputed Principal Balance of
such Class shall be payable to the extent of Available Funds as specified in
the related Series Supplement.

         In the case of a Class or Classes of Bonds which are Variable Rate
Bonds, the related Series Supplement shall specify the method of calculating
the Bond Interest Rate at any time to be borne by such Variable Rate Bonds.  On
each Interest Determination Date relative to a Class of Variable Rate Bonds the
interest rate of which is calculated by reference to an Index, until such
Variable Rate Bonds are paid in full, the Trustee shall determine the rate of
interest pursuant to the relevant Index for the purposes of such Interest
Determination Date in accordance with the mechanism specified in the related
Series Supplement, and the resulting Bond Interest Rate to be applicable to
such Variable Rate Bonds for the next Variable Rate Interest Accrual Period.

         Promptly after its determination thereof, the Trustee shall advise the
Issuer of the rate of interest applicable to each Class of  Variable Rate Bonds
of a Series for the next succeeding Variable Rate Interest Accrual Period.

         In determining LIBOR or the Reserve Interest Rate and the resulting
Bond Interest Rate for each relevant Variable Rate Interest Accrual Period for
any relevant Class of Variable Rate Bonds, the Trustee may conclusively rely
and shall be protected in relying upon the offered rates quoted (whether quoted
in writing, electronically or orally) by the Reference Banks or other banks as
to LIBOR or the Reserve Interest Rates, as appropriate, in effect from time to
time.  The Trustee shall





                                      -31-
<PAGE>   34
have no liability or responsibility to any Person for (i) its selection of
other banks for purposes of determining the Reserve Interest Rate or (ii) its
inability, following a good faith reasonable effort, to determine LIBOR or a
Reserve Interest Rate, all as provided for in the definition of "LIBOR" in the
related Series Supplement.

         The establishment of a rate of interest by reference to an Index and
the Reserve Interest Rate and the resulting Bond Interest Rate for each
relevant Variable Rate Interest Accrual Period relative to a Series of Bonds
shall (in the absence of manifest error) be final, conclusive and binding upon
the Holder or the Issuer and any of their respective partners, beneficiaries,
agents, officers, directors, employees or successors or assigns.

         Unless otherwise specified in the related Series Supplement,
calculation of the amount of interest accrued on the Bonds of any Class of any
Series during an Interest Accrual Period shall be made on the assumption that
any payment of principal on the Bonds of such Class made on a Principal
Reduction Date occurring during such Interest Accrual Period (other than on the
first day thereof) was instead paid on the first day of such Interest Accrual
Period.

         Any Unpaid Interest on a Class of Bonds shall be paid subject to and
as provided in the related Series Supplement.  Unless otherwise specified in
the related Series Supplement, no interest shall accrue on any Unpaid Interest.

         Notwithstanding any of the foregoing provisions with respect to
payments of principal of and interest on the Bonds, if the Bonds of a Series
have become or been declared due and payable following an Event of Default and
such acceleration of maturity and its consequences have not been rescinded and
annulled,  payments of principal of and interest on such Bonds shall be made in
accordance with Section 5.8.

         Each Bond shall bear upon the face thereof the designation so selected
for the Series and Class to which it belongs.

         Each Series of Bonds shall be created by a Series Supplement
authorized by the Board of Directors and establishing the terms and provisions
of such Series, specifying the Certificates and any other property to be
included in the Trust Estate therefor and Granting such Trust Estate as
security for the Series of Bonds created thereby.  The several Series may
differ in respect of any of the following matters:

         (1)     designation of the Series;

         (2)     dating of the Bonds of the Series and Accrual Date;

         (3)     the number of Classes, including the number of Classes of
                 Compound Interest Bonds, if any, the number of Classes of SAB

                 Bonds, if any, the number of Classes of Junior Bonds, if any,

         (4)     the Bond Interest Rate (if any) for each Class, and if such
                 Series of Bonds includes a Class or Classes of Variable Rate

                 Bonds includes a Class of Formula Rate Bonds, the method of
                 calculating the Bond Interest Rate borne at any time by such
                 Formula Rate Bonds;

                 each Class of Bonds of such Series entitled to payments of
                 principal;

         (6)     the place or places for the payment of the final installment
                 of principal;

         (7)     the priority of principal payments among the Classes entitled
                 to payments of principal and within each Class of the Series
                 entitled to payments of principal;

         (8)     the denominations of the Bonds of such Series;

                 Collection Account for such Series;

                 respect to the investment of funds in any Pledged Account for
                 such Series, and, if so, the standards applicable to such
                 Qualified GIC, including the conditions, if any, under which
                 the Trustee shall be required to terminate such Qualified GIC;

                 Section 2.12;

         (15)    whether calculations with respect to the mortgage loans
                 underlying the Certificates securing such Series are to be

notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Bonds or did not hold

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

         Each Bond shall be dated as of the date specified in the related Series
Supplement.

         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 Trustee or by any Authenticating Agent for the Series of which
it is a part 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 2.6      Temporary Bonds.

         Pending the preparation of Definitive Bonds, the Issuer may execute,
and upon Issuer Order the Trustee shall authenticate and deliver, temporary
Bonds which are printed, lithographed, typewritten, mimeographed or otherwise
produced, in any authorized denomination, substantially of the tenor of the
Definitive Bonds in lieu of which they may be so issued and with such
variations as the officers executing such Bonds may determine, as evidenced by
their execution of such Bonds.

         If temporary Bonds are issued, the Issuer will cause Definitive Bonds
to be prepared without unreasonable delay. After the preparation of Definitive
Bonds, the temporary Bonds shall be exchangeable for Definitive Bonds upon
surrender of the temporary Bonds at the office or agency of the Issuer to be
maintained as provided in Section 3.2, without charge to the Holder.  Upon
surrender or cancellation of any one or more temporary Bonds, the Issuer shall
execute and the Trustee shall authenticate and deliver and exchange therefor a
like principal amount of Definitive Bonds of the same Series and Class and of
authorized denominations.  Until so exchanged, the temporary Bonds shall in all
respects be entitled to the same benefits under this Indenture as Definitive
Bonds of the same Class and Series.


         Section 2.7      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 Trustee is hereby initially appointed "Bond Registrar" for the
purpose of registering Bonds and transfers of Bonds as herein provided.  Upon
any resignation of any Bond Registrar appointed by the Issuer, the Issuer shall
promptly appoint a successor or, in the absence of such appointment, shall
assume the duties of Bond Registrar.  In the event that the Trustee is acting
as Bond Registrar and the Trustee resigns as Trustee with respect to one or
more Series of Bonds, the Trustee may resign as Bond Registrar with respect to
the Bonds of such Series or Classes, as applicable.





                                      -38-
<PAGE>   41
         Each Authenticating Agent for a Series, unless it is appointed Bond
Registrar for such Series, and the Trustee, for any Series for which it is not
the Bond Registrar, shall be a co-Bond Registrar for such Series.  The Issuer
shall cause each co-Bond Registrar for a Series to furnish the Bond Registrar
for such Series promptly after each authentication of a Bond by it appropriate
information with respect thereto for entry by the Bond Registrar into the Bond
Register.  If the Trustee shall at any time not be authorized to keep and
maintain the Bond Register, the Trustee shall have the right to inspect such
Bond Register at all reasonable times and to rely conclusively upon a
certificate of the Person in charge of the Bond Register as to the names and
addresses of the Holders of the Bonds and the principal amounts and numbers of
such Bonds as held.  In the event that the Trustee is acting as Authenticating
Agent and the Trustee resigns as Trustee with respect to one or more Series of
Bonds, the Trustee may resign as Authenticating Agent with respect to the Bonds
of such Series or Classes, as applicable.

         Subject to restrictions, if any, in the related Series Supplement,
upon surrender for registration of transfer of any Bond at the office or agency
of the Issuer to be maintained as provided in Section 3.2, the Issuer shall
execute, and the Trustee 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 Series and of a like aggregate principal amount and
Class.

         At the option of the Holder, Bonds may be exchanged for other Bonds of
any authorized denominations, of the same Series and of a like aggregate
initial principal amount and Class, upon surrender of the Bonds to be exchanged
at such office or agency.  Bonds (other than Book Entry Bonds) of a Class which
are subject to redemption at the request of Bondholders and which are redeemed
in part, but not in whole, pursuant to Section 10.4 shall be surrendered at
such office or agency in exchange for new Bond certificates, without service
charge, in an aggregate principal amount equal to and in exchange for the
unredeemed portion of such Bond so surrendered.  Whenever any Bonds are so
surrendered for exchange, the Issuer shall execute, and the Trustee shall
authenticate and deliver, the Bonds which the Bondholder making the exchange is
entitled to receive.

         Subject to restrictions, if any, in the related Series Supplement, 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 Trustee 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 or 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,
other than exchanges pursuant to Section 2.8 not involving any transfer.





                                      -39-
<PAGE>   42
         Except as otherwise specified in the related Series Supplement,
neither the Issuer nor the Bond Registrar shall be required to issue, register
the transfer of or exchange any Bonds which are subject to redemption at the
request of Bondholders of any Series during a period beginning at the opening
of business five (5) Business Days prior to the selection of Bonds of that
Series to be redeemed pursuant to Bondholder redemption under Section 10.4 and
ending at the close of business on the day of the mailing of any relevant
notice of redemption.  No Bond which has been tendered for Bondholder
redemption may be transferred or exchanged unless such request for redemption
is withdrawn.

         In the case of a Class of Book Entry Bonds, the provisions of this
Section 2.7 may be supplemented by provisions in the related Series Supplement
and by applicable rules established by the Clearing Agency for such Class
providing for transfer of registration of Book Entry Bonds on the books of the
Clearing Agency.


         Section 2.8      Mutilated, Destroyed, Lost or Stolen Bonds.

         If (1) any mutilated Bond is surrendered to the Trustee or the Trustee
receives evidence to its satisfaction of the destruction, loss or theft of any
Bond, and (2) there is delivered to the Trustee such security or indemnity as
may be required by it to save each of the Issuer and the Trustee harmless,
then, in the absence of notice to the Issuer or the Trustee that such Bond has
been acquired by a bona fide purchaser, the Issuer shall execute and upon its
request the Trustee 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 Series, tenor, aggregate initial principal amount and Class bearing a
number not contemporaneously outstanding; provided, however, that 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.  If, after the
delivery of such new Bond or payment of a destroyed, lost or stolen Bond
pursuant to the proviso to the preceding sentence, 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 Trustee shall be entitled to recover
such new Bond (or such payment) from the Person to whom it was delivered or any
Person taking such new Bond from such Person, 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 Trustee in connection therewith.

         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 Trustee or
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





                                      -40-
<PAGE>   43
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 Series 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 2.9      Payments of Principal and Interest.

                 (a)      Any installment of interest or principal on a Bond,
         or the Redemption Price of any Bond called for redemption, payable on
         any Bonds of any Series which 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 (i) check mailed to such Person's address as it
         appears in the Bond Register on such Record Date, or (ii) upon written
         request made at least five business days prior to the applicable
         Record Date by any Holder of a Bond or Bonds of a particular Class
         having an aggregate Original Principal Amount that is in excess of the
         lesser of (x) $5,000,000 and (y) two-thirds of the aggregate Original
         Principal Amount of all Bonds of such Class, by wire transfer to a
         U.S. depository institution satisfactory to the Trustee, or by such
         other means of payment as such Holder and the Trustee may agree.  Any
         installment of interest or principal not punctually paid or duly
         provided for shall be payable in the manner and to the Persons
         specified in subsection (c) of this Section 2.9.

                 (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 or by the allocation of any
         Realized Losses or a Junior Bond Write Down Amount to such Bond 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 or allocation of losses is
         noted on such Bond.  The final installment of principal of each Bond
         (including the Redemption Price of any Bond called for redemption, if
         such 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 office
         or agency of the Issuer maintained by it for such purpose in the
         Borough of Manhattan, the City of New York, State of New York,
         pursuant to Section 3.2.

                 Whenever, on the basis of Distributions on the Certificates
         securing a Series received and expected to be received on the related
         Distribution Date, the Issuer expects that the entire remaining unpaid
         principal amount of any Bonds of such Series will become due and
         payable on the next Principal Payment Date, unless specified otherwise
         in the related Series Supplement it shall mail or cause to be mailed,
         no later than five days prior to such Principal





                                      -41-
<PAGE>   44
         Payment Date, to each Person in whose name a Bond to be so retired is
         registered at the close of business on the tenth Business Day prior to
         such Principal Payment Date, notwithstanding the Record Date otherwise
         applicable with respect to such Series, a notice to the effect that:

                       (i)        the Issuer expects that funds sufficient to
                 pay such final installment will be available in the Collection
                 Account on such Principal Payment Date, and

                      (ii)        if such funds are available, (A) such final
                 installment will be payable on such Principal Payment Date,
                 but only upon presentation and surrender of such Bond at the
                 office or agency of the Issuer maintained for such purpose
                 pursuant to Section 3.2 (the address of which shall be set
                 forth in such notice), and (B) no interest shall accrue on
                 such Bond after such Principal Payment Date.


         Notices in connection with redemptions or special redemptions of Bonds
         shall contain the information set forth in, and be mailed in
         accordance with, Section 10.2.

                 (c)      If the entire amount of Accrued Bond Interest on any
         Class of Bonds of a Series is not paid in full on any Interest Payment
         Date by reason of a shortfall in Available Funds over the amount
         required to pay such Accrued Bond Interest and any amount required to
         be paid out of Available Funds in priority to such Accrued Bond
         Interest, the amount of interest not paid on such Interest Payment
         Date (such amount being the "Unpaid Interest") shall be payable on the
         following Interest Payment Date, to the extent that Available Funds on
         such following Interest Payment Date are sufficient and subject at all
         times to any order of priority of payments out of Available Funds
         specified in the related Series Supplement.  No interest shall accrue
         or be payable on any amounts of Unpaid Interest.

                 If the entire Principal Distribution Amount or aggregate
         Accrued Bond Interest payable out of Available Funds on any Series of
         Bonds on a Payment Date, or the entire Redemption Price payable in
         connection with the redemption in whole of any Bond,  which is due and
         payable on any Redemption Date, shall not have been punctually paid or
         duly provided for when and as due and payable (any Bond on which such
         an amount due and payable has not been punctually paid or duly
         provided for being hereinafter referred to as an "Overdue Bond"), then
         each such amount, together with, in the case of any Redemption Price
         not paid when due, interest thereon from the date such amount was due
         until paid, at the Bond Interest Rate of the related Bonds, shall be
         payable on each subsequent Special Payment Date, to the extent only
         that funds are available therefor in the related Collection Account,
         to the Person entitled thereto as provided below.  No interest shall
         accrue or be payable on any Overdue Bond or any unpaid interest in
         respect thereof except as expressly provided above.

                 Any reduction in the principal amount of any Overdue Bond (or
         one or more Predecessor Bonds) effected by any payments made on a
         Special Payment Date shall be





                                      -42-
<PAGE>   45
         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.  Payments
         of interest on any overdue portion of the Redemption Price of any Bond
         called for redemption  shall, except as provided below with respect to
         payment of the entire amount remaining due on an Overdue Bond, be made
         to the Person entitled thereto as provided below by check mailed to
         such Person's address as it appears in the Bond Register or, if the
         criteria specified in paragraph (ii) of Section 2.9(a) are fulfilled,
         by wire transfer to a depository institution satisfactory to the
         Trustee, or by such other means as may be agreed between the Trustee
         and the Holder of such Bond.

                 If funds sufficient to pay the entire amount remaining due on
         any Overdue Bonds of a particular Class are expected to be available
         on the next Special Payment Date for such Series, as shown on the
         Special Payment Date Statement for such Special Payment Date, the
         Trustee, on behalf of the Issuer, will notify each Person in whose
         name an Overdue Bond to be so retired is registered at the close of
         business on the Special Record Date that would otherwise be applicable
         to such Special Payment Date, by notice mailed no later than five days
         after such otherwise applicable Special Record Date, that sufficient
         funds are expected to be available to make such payment and that, if
         such funds are available, such payment will be made only upon
         presentation and surrender of such Overdue Bond at the office or
         agency of the Issuer maintained for such purpose pursuant to Section
         3.2 (the address of which shall be set forth in such notice).  Upon
         the giving of such notice, the entire amount then due and payable on
         any such Overdue Bond shall, if sufficient funds are so available
         therefor, be payable only upon presentation and surrender of such
         Overdue Bond to the office or agency of the Issuer maintained for that
         purpose.

                 Other amounts payable with respect to any Overdue Bond as
         provided above on any Special Payment Date shall be payable (i) to the
         Person in whose name that Bond (or one or more Predecessor Bonds) is
         registered at the close of business on the Special Record Date for
         such Special Payment Date or (ii) in any other lawful manner not
         inconsistent with the requirements of any securities exchange on which
         such Bond may be listed and upon such notice as may be required by
         such exchange, if, after notice given by the Issuer to the Trustee of
         the proposed payment pursuant to this provision, such manner of
         payment shall be deemed practicable by the Trustee.

                 (d)      Subject to the foregoing provisions of this Section,
         each Bond delivered under this Indenture upon registration of transfer
         of or in exchange for or in lieu of any other Bond shall carry the
         rights to unpaid principal and interest that were carried by such
         other Bond.  Any checks mailed pursuant to subsection (a) or (c) of
         this Section 2.9 and returned undelivered shall be held in accordance
         with Section 3.3.

                 (e)      Not later than each Calculation Date for a Series,
         the Trustee shall prepare and deliver to the Issuer a Payment Date
         Statement with respect to the following Payment Date setting forth:

                       (i)        the Debt Service Requirement with respect to

                      (ii)        the aggregate amount of interest accrued
                 during the Interest Accrual Period relating to such Payment
                 Date on all Outstanding Bonds of such Series;

                     (iii)        the aggregate amount of Accrued Bond Interest
                 payable (to the extent of Available Funds) on each Class of
                 Bonds of such Series then Outstanding, in accordance with the
                 order of priority of payment in the Series Supplement;

                      (iv)        the amount of Net Interest Shortfalls and the
                 interest portion of all Realized Losses allocable to the Bonds
                 of such Series, or any Class or Classes thereof, on such
                 Payment Date;

                       (v)        the aggregate amount of principal payable out
                 of Available Funds for such Payment Date in respect of each
                 Class of Bonds of such Series then Outstanding, the principal
                 portion of any Realized Losses then allocable to the Bonds of
                 such Series and the Classes of Bonds to which such Realized
                 Losses are required to be allocated pursuant to the related
                 Series Supplement, and the amount of any Junior Bond Writedown
                 Amount then allocable to any Class of Junior Bonds of such
                 Series and the Class or Classes of Junior Bonds to which it is
                 allocable;

                      (vi)        if such following Payment Date is an Initial
                 Interest Payment Date for any Class of Compound Interest Bonds
                 of such Series, the amount of interest payable thereon on such
                 Interest Payment Date, the amount of the installment of
                 principal, if any, due and payable on such Class of Compound
                 Interest Bonds on such Payment Date, and the amount, if any,
                 of accrued interest to be added to the principal of such Class
                 of Compound Interest Bonds on such Payment Date;

                     (vii)        whether the amount expected to be available
                 in the Collection Account on such Payment Date will be
                 sufficient to pay on such Payment Date all amounts specified
                 in clauses (iii) and (v) above, and, if not, the percentages
                 of each such amount which may be paid in accordance with the

                 the execution of the Series Supplement for such Series
                 requires the requalification of this Indenture under the TIA,
                 or that no requalification of the Indenture under the TIA is

                 in the case of Certificates issuable in book-entry form only,
                 in lieu of delivering such Certificates the Issuer shall take
                 such actions to effect the Grant thereof to the Trustee as are
                 specified in the related Series Supplement.

                 (k)      A certificate of an Independent Person appointed by
         an Issuer Order, whose regular business activity includes valuing
         securities similar to the Certificates securing such Series, as to the
         fair market value of such Certificates, which determination of fair
         market value shall, unless otherwise provided in the related Series
         Supplement, be based upon generally available market quotations as of
         a date not earlier than three Business Days prior to the related
         Closing Date.

                 (l)      Such other documents, certificates, instruments or
         opinions as may be required by the terms of the Series Supplement
         creating such Series of Bonds.

         Section 2.13     Book Entry Bonds.

         Unless provided otherwise in the related Series Supplement, each Class

Bonds may not be transferred by the Trustee or Bond Registrar except under the
conditions, if any, described in the related Series Supplement.  In such case,
the Trustee shall deal with the Clearing Agency and Clearing Agency
Participants as representatives of the Beneficial Owners of such Bonds for
purposes of exercising the rights of Bondholders hereunder, as provided in the
related Series Supplement.  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 2.14     Termination of Book Entry System.

         (a)     Except as otherwise provided in the related Series Supplement,
the book entry system through the Clearing Agency with respect to any Class of
Book Entry Bonds may be terminated upon the happening of any of the following:

              (i)         The Clearing Agency or the Issuer advises the Trustee
         that the Clearing Agency is no longer willing or able to properly
         discharge its responsibilities under the respective Letter Agreement
         and the Issuer is unable to locate a qualified successor clearing
         agency satisfactory to the Trustee and the Issuer;

             (ii)         The Issuer, in its sole discretion but with the
         consent of the Trustee, elects to terminate the book entry system by
         notice to the Clearing Agency and the Trustee; or

            (iii)         After the occurrence of an Event of Default (at which
         time the Trustee shall use all reasonable efforts to promptly notify
         each Beneficial Owner through the Clearing Agency of such Event of
         Default when such notice shall be given pursuant to Section 6.2, the
         Beneficial Owners of a majority in Aggregate Current Principal Amount
         of the Book Entry Bonds advise the 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 Bond certificates being issued to any
         person other than the Clearing Agency or its nominee is no longer in
         the best interests of the Beneficial Owners.

         (b)     Upon the occurrence of any event described in subsection (a)
above, the Trustee shall use all reasonable efforts to notify all Beneficial
Owners, through the Clearing Agency, of the occurrence of such event and of the
availability of Definitive Bond certificates to Beneficial Owners requesting
the same, in an Aggregate Current Principal Amount 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 or special
redemption.  Definitive Bond certificates shall be issued only upon surrender
to the Trustee of the Bond by the Clearing Agency, accompanied by registration
instructions for the Definitive Bond certificates.  Neither the Issuer nor the
Trustee shall be liable for any delay in delivery of such instructions and may
conclusively rely on, and shall be protected in relying on, such instructions.
Upon issuance of the Definitive Bond certificates, all references herein and in
the Series Supplement to obligations imposed upon or to be performed by

Definitive Bonds shall be applicable.


         Section 2.15     Restrictions on Transfer of Certain Classes of Bonds.

                 (a)      No legal or beneficial interest in all or any portion
         of any Residual Bonds of any Series may be transferred directly or
         indirectly to (i) a Disqualified Organization or a an agent of a
         Disqualified Organization (including a broker, nominee, or middleman),
         (ii) an entity that holds REMIC 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"), or (iii) an individual,
         corporation, partnership or other person unless such transferee (A) is
         not a Non-U.S. Person or (B) is a Non-U.S. Person that will hold such
         Residual Bond in connection with the conduct of a trade or business
         within the United States and has furnished the transferor and the
         Trustee with an effective Internal Revenue Service Form 4224 or (C) is
         a Non-U.S. Person that has delivered to both the transferor and the
         Trustee an opinion of a nationally recognized tax counsel to the
         effect that the transfer of a Residual Bond to it is in accordance
         with the requirements of the Code and the regulations promulgated
         thereunder and that such transfer of a Residual Bond will not be
         disregarded for federal income tax purposes (any such person who is
         not covered by clause (A), (B) or (C) above being referred to herein
         as  "Non-permitted Foreign Holder"), and any such purported transfer
         shall be void and have no effect.  The Trustee shall not authenticate
         and deliver a Residual Bond in connection with any transfer thereof
         unless the transferor shall have provided to the Trustee an affidavit,
         substantially in the form attached as Exhibit B to the related Series
         Supplement, signed by the transferee.

                 The affidavit described in the preceding paragraph, if not
         executed in connection with the initial issuance of the Residual Bonds
         of any relevant Series, shall be accompanied by a written statement in
         the form attached as Exhibit E to the related Series Supplement,
         signed by the transferor of any such Residual Bond.  The Residual
         Bonds (if any) of each Series shall bear a legend referring to the
         foregoing restrictions contained in this paragraph and the preceding
         paragraph.

                 Upon written notice to the Trustee that any legal or
         beneficial interest in any portion of a Residual Bond of any Series
         has been transferred, directly or indirectly, to a Disqualified
         Organization or agent thereof (including a broker, nominee, or
         middleman) in contravention of the foregoing restrictions, (i) such
         transferee shall be deemed to hold such Residual Bond in constructive
         trust for the last transferor who was not a Disqualified Organization
         or agent thereof, and such transferor shall be restored as the owner
         of such Residual Bond as completely as if such transfer had never
         occurred, provided that the Trustee may, but is not required to,
         recover any payments made to such transferee with respect to such
         Residual Bond and return such recovery to the transferor, and (ii) the
         Trustee agrees, at the Issuer's expense, to furnish to the Internal
         Revenue Service and to any transferor of such Residual





                                      -55-
<PAGE>   58
         Bond or such agent (within 60 days of the request therefor by the
         transferor or agent) such information necessary to the application of
         Section 860E(e) of the Code as may be required by the Code, including
         but not limited to the present value of the total anticipated excess
         inclusions with respect to such Residual Bond (or portion thereof) for
         periods after such transfer.  At the election of the Trustee, the cost
         to the Trustee of computing and furnishing such information may be
         charged to the transferor or such agent referred to above; however,
         the Trustee shall in no event be excused from furnishing such
         information.

                 The restrictions on transfers of the Residual Bonds of any
         Series set forth in the preceding three paragraphs shall cease to
         apply to transfers (and the applicable portions of the legend to such
         Residual Bonds may be deleted) after delivery to the Trustee of an
         Opinion of Counsel to the effect that the elimination of such
         restrictions will not cause a REMIC Loss.

                 (b)      No transfer of a Restricted Bond of any Series shall
         be made unless such transfer is exempt from the registration
         requirements of the Securities Act of 1933, as amended (the "Act"),
         and any applicable state securities laws, or is made in accordance
         with the Act and any applicable state securities laws.  As a condition
         precedent to the transfer of a Restricted Bond, (i) the Trustee shall
         require a written opinion of counsel, which counsel shall be
         acceptable to the Trustee, that such transfer may be made pursuant to
         an exemption from the Act and any applicable state securities laws
         (which opinion shall not be at the expense of the Trustee) or (ii) the
         Trustee shall require the transferee to execute an investment letter
         in the form substantially as set forth in Exhibit F to the related
         Series Supplement or in such other form as may be acceptable to the
         Trustee, certifying as to the facts surrounding such transfer.  The
         holder of any Restricted Bond desiring to effect the transfer thereof
         shall, and hereby agrees to, indemnify the Trustee and the Issuer
         against any liability that may result if the transfer thereof is not
         so exempt or is not made in accordance with such federal and state
         laws.  Such agreement to so indemnify the Trustee and the Issuer shall
         survive the termination of this Agreement.

                 (c)      No transfer of an ERISA Restricted Bond (if any) of a
         Series shall be made to any Person unless the Trustee has received (A)
         either (i) a certificate substantially in the form of Exhibit D to the
         related Series Supplement, from such transferee to the effect that
         such transferee is not a Plan or a Person that is using the assets of
         a Plan to acquire such ERISA Restricted Bond or (ii) a certificate in
         such form and substance as shall be satisfactory to the Trustee and
         the Issuer in lieu of the Certificate attached as Exhibit D or (B) an
         opinion of counsel, which counsel shall be satisfactory to the Trustee
         and the Issuer to the effect that the purchase and holding of such
         ERISA Restricted Bond will not constitute or result in the assets of
         the Trust Estate being deemed to be "plan assets" subject to the
         prohibited transactions provisions of ERISA or Section 4975 of the
         Code and will not subject the Trustee, the Certificate Trustee, the
         Administrator relative to such Series or the





                                      -56-
<PAGE>   59
         Issuer to any obligation in addition to those undertaken in this
         Indenture or in the related Pooling and Administration Agreement;
         provided, however, that the Trustee will not require such certificate
         or opinion if, as a result of a change of law or otherwise, counsel
         satisfactory to the Trustee has rendered an opinion to the effect that
         the purchase and holding of an ERISA Restricted Bond by a Plan or a
         Person that is purchasing or holding such ERISA Restricted Bond with
         the assets of a Plan will not constitute or result in a prohibited
         transaction under ERISA or Section 4975 of the Code.  The preparation
         and delivery of the certificate and opinions referred to above shall
         not be an expense of the Trust Estate, the Trust, the Certificate
         Trustee, the Administrator relative to such Series or the Issuer.

                          (i)     No transfer of an ERISA Prohibited Bond shall
                 be made to any Person unless the Trustee has received a
                 certificate (substantially in the form of Exhibit B to the
                 related  Series Supplement in the case of a Residual Bond, or
                 containing a certification substantially as set forth in
                 paragraph 17 of Exhibit B to the related Series Supplement, in
                 the case of an ERISA Prohibited Bond that is not a Residual
                 Bond) from such transferee to the effect that, among other
                 things, such transferee is not a Plan or a Person that is
                 using the assets of a Plan to acquire any such Bond.  The
                 preparation and delivery of such certificate shall not be an
                 expense of the Trust Estate, the Trustee, the Issuer.

                 (d)      Subject to Section 6.1 hereof, the Trustee may
         conclusively rely upon any certificate, affidavit or opinion delivered
         pursuant to Section 2.15(a), (b), or (c).

principal of, and interest on, the Bonds of each Series in accordance with the
terms of such Bonds and this Indenture.  The Bonds of each Series shall be non-
recourse obligations of the Issuer and shall be limited in right of payment to
amounts available from the Trust Estate relative to such Series 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 3.1, the provisions of this
Section 3.1 shall control.


         Section 3.2      Maintenance of Office or Agency.

         The Issuer will maintain in the Borough of Manhattan, the City of New
York, the State of New York an office or agency where Bonds may be presented or
surrendered for payment or 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 will give prompt written
notice to the Trustee of the location and any change in the location of such
office or agency.  Until written notice of any change in the location of such
office or agency is delivered to the Trustee or if at any time the Issuer shall
fail to maintain any such required office or agency or shall fail to furnish
the Trustee with the address thereof, Bonds may be so presented or surrendered,
and such notices and demands may be made or served, at the New York Office, and
the Issuer hereby appoints the New York Agent as its agent in the City of New
York, for the foregoing purposes.

         The Issuer may also from time to time designate one or more other
offices or agencies (in or outside the City of New York) 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, that (i) no such designation or
rescission shall in any manner relieve the Issuer of its obligation to maintain
an office or agency in the Borough of Manhattan, the City of New York, the
State of New York for the purposes set forth in the preceding paragraph, (ii)
presentations or surrenders of Bonds for payment may be made only in the City
of New York, the State of New York and (iii) any designation of an office or
agency for payment of Bonds shall be subject to Section 3.3.  The Issuer will
give prompt written notice to the Trustee of any such designation or rescission
and of any change in the location of any such other office or agency.

         Section 3.3      Money for Bond Payments to Be Held in Trust.

         All payments of amounts due and payable with respect to any Bonds
which are to be made from amounts withdrawn from the related Collection Account
pursuant to Section 8.2(c) or Section 5.8 shall be made on behalf of the Issuer
by the Trustee or by a Paying Agent, and no amounts so withdrawn from a
Collection Account for payments of Bonds shall be paid over to the Issuer under
any circumstances except as provided in this Section 3.3 or in Section 5.8.

         When the Issuer shall have a Paying Agent for a Series that is not
also the Bond Registrar for such Series, it shall furnish, or cause the Bond
Registrar for such Series to furnish, no later than

         (a)     the fifth calendar day after each Record Date for such Series, 
and

         (b)     the fifth calendar day after each Special Record Date
applicable to a Special Payment Date for such Series,

a list, in such form as such Paying Agent may reasonably require, of the names
and addresses of the Holders of Bonds of such Series and of the number of
Individual Bonds of each Class of such Series held by each such Holder.

         Whenever the Issuer shall have a Paying Agent other than the Trustee,
it will, on or before the Business Day next preceding each Payment Date and
Special Payment Date for each Series of Bonds, direct the 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
Collection Account for such Series), 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 Trustee for application in accordance
with Article VIII.

         Any Paying Agent shall be appointed by Issuer Order.  The Issuer shall
not appoint any Paying Agent (other than the Trustee) which is not, at the time
of such appointment, a depository institution or trust company whose
obligations would be Eligible Investments pursuant to clause (ii) of the
definition of the term "Eligible Investment".  In the event that the Trustee is
acting as Paying Agent and the Trustee resigns as Trustee with respect to one
or more Series of Bonds (or to the extent permitted in any Series Supplement,
with respect to one or more Classes within a Series), the Trustee may resign as
Paying Agent with respect to the Bonds of such Series or Classes, as
applicable.  The Issuer will cause each Paying Agent other than the Trustee to
execute and deliver to the Trustee an instrument in which such Paying Agent
shall agree with the Trustee (and if the Trustee acts as Paying Agent, it
hereby so agrees), subject to the provisions of this Section, that such Paying
Agent will:





                                      -59-
<PAGE>   62
                 (1)      allocate all sums received for payment to the Holders
         of Bonds of each Series for which it is acting as Paying Agent on each
         Payment Date and Special Payment Date among such Holders in the
         proportion specified in the applicable Payment Date Statement and
         Special Payment Date Statement, as the case may be, 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 Trustee, immediately
         resign as a Paying Agent and forthwith pay to the Trustee all sums
         held by it in trust for the payment of Bonds if at any time it 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 Trustee, give the
         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 Series of Bonds for which it is acting as Paying Agent;

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

                 (6)      comply with all requirements of the Code with respect
         to the 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 Class of Bonds,
         the Issuer shall have first provided the calculations pertaining
         thereto to the Trustee.

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

         Except as provided by applicable law, any money held by the 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
prior to the date on which such amount would escheat to a governmental





                                      -60-
<PAGE>   63
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 Trustee
or such Paying Agent with respect to such trust money shall thereupon cease;
provided, however, that if an election has been or will be made to treat the
Trust Estate securing the Series or any other assets specified in a REMIC
election relative to such Series, as a REMIC, any such unclaimed funds shall be
paid to the state pursuant to applicable escheat laws and in such event the
Holder of such Bond shall thereafter look only to such state for payment
thereof and all liability of the Issuer, the Trustee or such Paying Agent with
respect to such trust money shall thereupon cease.  The 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 such repayment
to Holders whose Bonds have been called but have not been surrendered for
redemption or whose right to or interest in moneys due and payable but not
claimed is determinable from the records of the Trustee or any Agent, at the
last address of record for each such Holder).


         Section 3.4      Corporate Existence.

                 (a)      Subject to Section 3.4(b) and (c), the Issuer will
         keep in full effect its existence, rights and franchises as a
         corporation under the laws of the State of Delaware or under the laws
         of any other state or the United States of America, and will obtain
         and preserve its qualification to do business as a foreign corporation
         in each jurisdiction in which such qualification is or shall be
         necessary to protect the validity and enforceability of this
         Indenture, the Bonds or any of the Certificates.

                 (b)      Any corporation into which the Issuer hereunder may
         be merged or with which it may be consolidated, or any corporation
         resulting from any merger or consolidation to which such Issuer
         hereunder shall be a party, shall be the successor Issuer under this
         Indenture without the execution or filing of any paper, instrument or
         further act to be done on the part of the parties hereto, anything
         herein, or in any agreement relating to such merger or consolidation,
         by which any such Issuer may seek to retain certain powers, rights and
         privileges theretofore obtaining for any period of time following such
         merger or consolidation, to the contrary notwithstanding.

                 (c)      Upon any consolidation or merger of or other
         succession to the Issuer in accordance with Section 3.4(b) hereof, the
         Person formed by or surviving such consolidation or merger (if other
         than the Issuer) may exercise every right and power of the Issuer
         under this Indenture with the same effect as if such Person had been
         named as the Issuer herein.


         Section 3.5      Protection of Trust Estate.





                                      -61-
<PAGE>   64
         The Issuer will from time to time execute and deliver all such
supplements and amendments hereto and all such financing statements,
continuation statements, instruments of further assurance, and other
instruments, and will take such other action as may be necessary or advisable
to

              (i)         Grant more effectively all or any portion of a Trust 
         Estate,

             (ii)         maintain or preserve the lien of this Indenture or
         carry out more effectively the purposes hereof,

            (iii)         perfect, publish notice of, or protect the validity
         of, any Grant made or to be made by this Indenture,

             (iv)         enforce any of the Certificates, or

              (v)         preserve and defend title to any Certificate or other
         instrument included in a Trust Estate and the rights of the Trustee,
         and of the Bondholders of the Series secured thereby, in such
         Certificate or other instrument against the claims of all persons and
         parties.

The Issuer hereby designates the Trustee its agent and attorney-in-fact to
execute, upon the Issuer's failure to do so, any financing statement,
continuation statement or other instrument required pursuant to this Section
3.5; provided, however, that such designation shall not be deemed to create a
duty in the Trustee to monitor the compliance of the Issuer with the foregoing
covenants and provided, further, that the duty of the Trustee to execute any
instrument required pursuant to this Section 3.5 shall arise only if the
Trustee has knowledge of any failure of the Issuer to comply with the
provisions of this Section 3.5.

         Section 3.6      Opinions as to Trust Estate.

         On or before February 15 in each calendar year, beginning, with
respect to each Series, with the first calendar year commencing more than three
months after the Closing Date for such Series, the Issuer shall furnish to the
Trustee an Opinion of Counsel either stating that, in the opinion of such
counsel, such action has been taken with respect to the recording, filing,
re-recording and re-filing of this Indenture, any indentures supplemental
hereto and any other requisite documents and with respect to the execution and
filing of any financing statements and continuation statements as is necessary
to maintain the lien and security interest created by this Indenture with
respect to the Trust Estate for such Series and reciting the details of such
action or stating that in the opinion of such counsel no such action is
necessary to maintain such lien and security interest.  Such Opinion of Counsel
shall also describe the recording, filing, re-recording and re-filing of this
Indenture, any indentures supplemental hereto and any other requisite documents
and the execution and filing of any financing statements and continuation
statements that will, in the opinion of such counsel, be





                                      -62-
<PAGE>   65
required to maintain the lien and security interest of this Indenture with
respect to the Trust Estate for such Series until February 15 in the following
calendar year.

         The Trustee shall not remove any portion of any Trust Estate that
consists of money or is evidenced by an instrument, certificate or other
writing from the jurisdiction in which it was held at the date the most recent
opinion of Counsel was delivered pursuant to this Section 3.6 (or from the
jurisdiction in which it was held as described in the Opinion of Counsel
delivered at the Closing Date pursuant to Section 2.12(c), if no Opinion of
Counsel has yet been delivered pursuant to this Section 3.6) or cause or permit
ownership or the pledge of any portion of the Trust Estate that consists of
book-entry securities to be recorded on the books of a Person located in a
different jurisdiction from the jurisdiction in which such ownership or pledge
was recorded at such date unless the Trustee shall have first received an
Opinion of Counsel to the effect that the lien and security interest created by
this Indenture with respect to such property will continue to be maintained
after giving effect to such action or actions.


         Section 3.7      Performance of Obligations.

         The Issuer will not take any action or permit any action to be taken
by others which would release any Person from any of such Person's covenants or
obligations under any instrument included in a Trust Estate, or which would
result in the amendment, hypothecation, subordination, termination or discharge
of, or impair the validity or effectiveness of, any such instrument, except as
expressly provided in this Indenture.


         Section 3.8      Negative Covenants.

         The Issuer will not:

                 (a)      sell, transfer, exchange or otherwise dispose of any
         portion of a Trust Estate except as expressly permitted by this
         Indenture;

                 (b)      claim any credit on, or make any deduction from, the
         principal of, or interest on, any of the Bonds by reason of the
         payment of any taxes levied or assessed upon any portion of a Trust
         Estate;

                 (c)      (i) engage in any business or activity other than in
         connection with, or relating to, the issuance of Bonds pursuant to
         this Indenture or any Series Supplement or the issuance of bonds
         permitted under clause (d) below, or (ii) amend Article III or VIII of
         its Certificate of Incorporation, as in effect on the Closing Date for
         the initial Series of Bonds, without, in each case, the consent of the
         Holders of not less than 66 2/3% of the Aggregate Current Principal
         Amount of the Bonds of each Series then Outstanding;





                                      -63-
<PAGE>   66
                 (d)      issue bonds under any other indenture unless such
         bonds are non-recourse obligations of the Issuer;

                 (e)      incur, assume, guaranty or agree to indemnify any
         indebtedness of any Person, except for such indebtedness as may be
         incurred by the Issuer in connection with the issuance of a Series of
         Bonds pursuant to this Indenture or any Series Supplement or as
         permitted under clause (d) above or indebtedness which, if consisting
         of indebtedness other than Bonds or indebtedness permitted under
         clause (d) above, (i) shall either be (1) subordinate to each Series
         of Bonds issued pursuant to the Indenture or (2) secured by collateral
         other than the Trust Estate and to which the creditor with respect to
         such indebtedness has recourse only to such collateral and not to any
         other assets of the Issuer and (ii) shall provide that the holder
         thereof may not file a petition in any bankruptcy or insolvency
         proceeding with respect to the Issuer until not less than 91 days
         after payment in full of all Outstanding Bonds issued pursuant to this
         Indenture;

                 (f)      dissolve or liquidate in whole or in part;

                 (g)      merge or consolidate with any corporation other than
         an Affiliate of the Issuer, any such merger or consolidation with an
         Affiliate of the Issuer to be subject to the following conditions:

                          (1)     the surviving or resulting entity shall be a
                 corporation organized under the laws of the United States or
                 any state thereof and its certificate of incorporation shall
                 contain substantially the same restrictions as are contained
                 in Articles III and VIII of the Issuer's Certificate of
                 Incorporation;

                          (2)     the surviving or resulting corporation (if
                 other than the Issuer) shall expressly assume by an indenture
                 supplemental hereto all of the Issuer's obligations hereunder;

                          (3)     the consummation of such merger or
                 consolidation shall not result in the lowering of any rating
                 of the Outstanding Bonds of any Series by the rating agencies
                 that rated the initial Series of Bonds; and

                          (4)     immediately after consummation of the merger
                 or consolidation no Default shall exist with respect to any
                 Series;

                 (h)      (1) permit the validity or effectiveness of this
         Indenture or any Grant under the related Series Supplement to be
         impaired, or permit the lien of this Indenture to be amended,
         hypothecated, subordinated, terminated or discharged with respect to
         any Series, or permit any Person to be released from any covenants or
         obligations with respect to any Series under this Indenture, except as
         may be expressly permitted hereby or by any Series





                                      -64-
<PAGE>   67
         Supplement, (2) permit any lien, charge, security interest, mortgage
         or other encumbrance (other than the lien of this Indenture or any
         Permitted Encumbrance) to be created on or extend to or otherwise
         arise upon or burden the Trust Estate for any Series or any part
         thereof or any interest therein or the proceeds thereof, so long as
         such proceeds remain a part of the Trust Estate, or (3) permit the
         lien of this Indenture not to constitute a valid first priority
         security interest in the Trust Estate securing any Series; or

                 (i)      take any action, or omit to take any action, if such
         action or omission may (i) cause any Trust Estate or any other assets
         securing a Series of Bonds and in respect of which a REMIC election
         has been made to fail to qualify as a REMIC during any taxable year,
         or (ii) cause or permit any REMIC relative to any Series to engage in
         any "prohibited transaction" as defined in Section 860F of the Code.

         Section 3.9      Annual Statement as to Compliance.

         On or before 120 days after the end of the first fiscal year of the
Issuer which ends more than three months after the Closing Date for a Series,
and each fiscal year thereafter, the Issuer shall deliver to the Trustee a
brief statement with respect to such Series, signed by its principal executive
officer, principal financial officer or principal accounting officer, that

                 (1)      a review of the fulfillment by the Issuer during such
         year of its obligations under this Indenture has been made under such
         officer's supervision; and

                 (2)      to the best of such officer's knowledge, based on
         such review, the Issuer has complied with all conditions and covenants
         under this Indenture throughout such year, or, if there has been a
         Default in the fulfillment of any such obligation, specifying each
         such Default known to such officer and the nature and status thereof.
         For purposes of this paragraph, such compliance shall be determined
         without regard to any period of grace or requirement of notice
         provided under the Indenture.


         Section 3.10     Contribution of Assets.

         Except as otherwise provided in the related Series Supplement, if an
election has been made or will be made to treat the Trust Estate or any other
assets specified in such election securing the related Series as a REMIC,
following the Closing Date, the Trustee shall not accept any contribution of
additional assets to the Trust Estate or such other assets, unless it has
received a Non-Disqualification Opinion with respect thereto and an opinion of
counsel that the contribution will not result in the imposition of a penalty
tax under the Code on the related REMIC.

         Section 3.11     Successor Substituted.

         Upon any consolidation or merger in accordance with Section 3.8(g),
the person resulting from or surviving such consolidation or merger (if other
than the Issuer) shall succeed to, and be substituted for, and may exercise
every right and power of the Issuer under the Indenture with the same effect as
if such Person had been named as the Issuer herein.  Promptly upon the
occurrence of any such succession, such Person shall give notice thereof to the
Trustee.

         Section 4.1      Satisfaction and Discharge of Indenture.

         Whenever the following conditions shall have been satisfied with
respect to a Series:

                          (A)     all Bonds of such Series theretofore
                 authenticated and delivered (other than (i) Bonds which have

                 paid as provided in Section 2.8, and (ii) Bonds for whose
                 payment money has theretofore been deposited in trust and

                          expense, of the Issuer,

                 and, in the case of any Series in respect of the assets
                 securing which a REMIC election or elections have been made,

         Certificate and an Opinion of Counsel each stating that all conditions
         precedent herein provided for the satisfaction and discharge of this
         Indenture with respect to such Series have been complied with;

then, upon Issuer Request, authorized by a Board Resolution, this Indenture and
the related Series Supplement and the lien, rights and interests created hereby
and thereby shall cease to be of further effect with respect to such Series,
and the Trustee and each co-trustee and separate trustee, if any, then acting

such instruments as may be necessary to acknowledge the satisfaction and
discharge of this Indenture and the related Series Supplement with respect to

each Series of Bonds for which such an election has been made or will be made,

the payment of all Outstanding Bonds of all Series shall not render this
Indenture inoperative or prevent the Issuer from issuing additional Series of
Bonds from time to time thereafter as herein provided.

         Notwithstanding the satisfaction and discharge of this Indenture with

the Trustee.

         Section 4.3      REMIC Matters.

                 (a)      Each Series Supplement shall contain a statement
         specifying whether or not it is intended that one or more REMIC
         elections be made in respect of the Trust Estate and other assets
         specified in such Series Supplement and securing the Bonds issued
         thereby.  If an election or elections are made as aforesaid, it is
         intended that each REMIC specified in the related Series Supplement
         shall constitute, and the affairs thereof shall be conducted so as to
         qualify each such REMIC as, a "real estate mortgage investment
         conduit" as defined in and in accordance with the REMIC Provisions.
         In furtherance of such intention, and with respect to each such REMIC,
         the Issuer covenants and agrees that it shall:

                       (i)        prepare and file, or cause to be prepared and
                 filed, in a timely manner, a U.S. Real Estate Mortgage
                 Investment Conduit Income Tax Return (Form 1066) and prepare
                 and file or cause to be prepared and filed with the Internal
                 Revenue Service and applicable state or local tax authorities
                 income tax or information returns for each taxable year with
                 respect to each calendar year as the taxable year and the
                 accrual method of accounting, containing such information and
                 at the times and in the manner as may be required by the Code
                 or state or local tax laws, regulations, or rules, and shall
                 furnish or cause to be furnished to the related Bondholders
                 the schedules, statements or information at such times and in
                 such manner as may be required thereby;

                      (ii)        within thirty days of the Closing Date of
                 each such Series, shall furnish or cause to be furnished to
                 the Internal Revenue Service, on Form 8811 or as otherwise may
                 be required by the Code, the name, title, address, and
                 telephone number of the person that the holders of the related
                 Bonds may contact for tax information relating thereto (and
                 the Issuer shall act as the representative of each relevant
                 Trust Estate for this purpose), together with such additional
                 information as may be required by such Form, and shall update
                 such information at the time or times in the manner required
                 by the Code;

                     (iii)        make or cause to be made an election on
                 behalf of such REMIC, to be treated as a REMIC on its federal
                 tax return for its first taxable year (and, if necessary,
                 under applicable state law);

                      (iv)        prepare and forward, or cause to be prepared
                 and forwarded, to the related Bondholders and to the Internal
                 Revenue Service and, if necessary, state tax authorities, all
                 information returns or reports, or furnish or cause to be
                 furnished by telephone, mail, publication or other appropriate
                 method such information, as and when required to be provided
                 to them in accordance with the REMIC Provisions,

                 including without limitation, the calculation of any original
                 issue discount using the Prepayment Assumption specified in
                 the related Series Supplement;

                       (v)        provide information necessary for the
                 computation of tax imposed on the transfer of a Residual
                 Interest of each such REMIC (including the information
                 required by Treasury Regulation 1.860D-1(b)(5)(ii)) to the
                 Internal Revenue Service and to a Disqualified Organization,
                 or an agent (including a broker, nominee or other middleman)
                 of a Disqualified Organization, or a pass-through entity in
                 which a Disqualified Organization is the record holder of an
                 interest and to any other Person specified in Section
                 860E(e)(3) and (6) of the Code as liable for the tax imposed
                 under Section 860E(e) of the Code (the reasonable cost of
                 computing and furnishing such information may be charged to
                 the Person liable for such tax);

                      (vi)        conduct the affairs of each such REMIC at all
                 time that any Bonds relative thereto are Outstanding so as to
                 maintain the status thereof as a REMIC under the REMIC
                 Provisions;

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

                    (viii)        exercise reasonable care not to allow the
                 creation of any "interests" in each such REMIC within the
                 meaning of Section 860D(d)(2) of the Code other than as
                 provided in the related Series Supplement;

                      (ix)        exercise reasonable care not to allow the
                 occurrence of any "prohibited transactions" within the meaning
                 of Section 860F of the Code in respect of any such REMIC,
                 unless the Issuer shall have provided a Non-Disqualification
                 Opinion to the Trustee that such occurrence would not result
                 in a REMIC Loss in respect of such REMIC;

                       (x)        exercise reasonable care not to allow such
                 REMIC to receive income from the performance of services or
                 from assets not permitted under the REMIC Provisions to be
                 held by a REMIC;

                      (xi)        pay from amounts in the Trust Estate the
                 amount of any federal or state law, including prohibited
                 transaction taxes, taxes on certain contributions to such
                 REMIC after the Startup Day relative thereto, and taxes on net
                 income from foreclosure property, imposed on such REMIC and as
                 the same shall be due and payable (but such obligation shall
                 not prevent the Issuer or any other appropriate Person from
                 contesting any such tax in appropriate proceedings and shall
                 not prevent the Issuer from withholding payment of such tax,
                 if permitted by law, pending the outcome of such proceedings);

                 Issuer or such other person as may be required to sign such
                 returns by the Code or state or local laws, regulations or
                 rules; and

                    (xiii)        maintain such records relating to each such
                 REMIC, including but not limited to the income, expenses,
                 individual mortgage loans (including mortgaged property)
                 relative to such REMIC, other assets and liabilities of the
                 Trust Estate relative to such REMIC, and the fair market value
                 and adjusted basis of the property of each determined at such
                 intervals as may be required by the Code, as may be necessary
                 to prepare the foregoing returns, schedules, statement or
                 information.

                 (b)      Reserved

                 (c)      The Issuer shall cause the first federal income tax
         return of each REMIC relative to a Series of Bonds to include the
         information required by Treasury Regulation Section 1.860D-1(d)(2) and
         Treasury Regulation Section 1.860F-4(b)(2).

                 (d)      Except as otherwise provided in the related Series
         Supplement, where an election has been made or will be made to treat
         the Trust Estate or any other assets specified in such election and
         securing the Series as one or more REMICs, the termination of each
         such REMIC shall be effected by the Issuer pursuant to a Qualified
         Liquidation and only after delivery by the Issuer to the Trustee of a
         Non-Disqualification Opinion.


         Section 4.4      Reinstatement.

         If the Trustee or any Paying Agent is unable to apply any money in
accordance with Sections 4.1 and 4.2 by reason of any legal proceeding or by
reason of any order or judgment of any court or governmental authority
enjoining, restraining or otherwise prohibiting such application, the Issuer's
obligations under the Indenture and the Bonds shall be revived and reinstated
as though no deposit had occurred pursuant to Section 4.1 until such time as
the Trustee or such Paying Agent is permitted to apply all such money or
obligations in accordance with Sections 4.1 and 4.2; provided, however, that if
the Issuer has made payment of interest on or principal of any of the Bonds
because of the reinstatement of its obligations, the Issuer shall be subrogated
to the Holders of the Bonds to receive such payment from the money or
obligations held by the Trustee or such Paying Agent.

         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,

entitlement or any Accrued Bond Interest or any Unpaid Interest on any Class of
Bonds of a Series by reason of the insufficiency of Available Funds on a
Payment Date and the order of allocation of payments from Available Funds
specified in the related Series Supplement, shall constitute an Event of
Default under this Indenture or any Series Supplement, it being expressly
agreed and understood that the Issuer's obligation to make payment on the Bonds
of any Series on any Payment Date constitutes an obligation to pay an aggregate
amount equal to the Available Funds on such Payment Date.

         (C)     Payments on the Bonds of any Series shall be made on each
Payment Date from Available Funds subject to and in accordance with the order
of priority of payments specified in the related Series Supplement.  No

delinquencies or Realized Losses on the mortgage loans evidenced by the
Conventional Certificates securing such Series or by the application to such
Bond of any portion of a Junior Bond Write Down Amount, or (b) a failure by any
Holder of a Bond of any Series to recover the full amount of any Accrued Bond
Interest or Unpaid Interest thereon by reason of the insufficiency of Available
Funds on any Payment Date and the order of allocation of payments from
Available Funds specified in the related Series Supplement.

         Section 5.2        Acceleration of Maturity; Rescission and Annulment.

         (A)     Except to the extent specified otherwise in the Series
Supplement relating to any Series of Bonds, if an Event of Default occurs and
is continuing with respect to a Series, then and in every such case the Holders
of Senior Bonds representing not less than 100% of the Aggregate Current
Principal Amount of the Outstanding Senior Bonds of that Series may declare all
the Bonds of that Series to be immediately due and payable, by a notice in
writing to the Issuer and the Trustee, and upon any such declaration of such
Bonds, an amount equal to (i) the Aggregate Imputed Principal Balance of the
Bonds of such Series at the time of such declaration; (ii) the aggregate of (x)
Accrued Bond Interest on each Class of Bonds of such Series that is due and
unpaid as of the Interest Payment Date most recently preceding  such
declaration, and (y) any Unpaid Interest outstanding as of the date of such
declaration, and (iii) an amount equal to the excess of (x) the





                                      -73-
<PAGE>   76
Aggregate Current Principal Amount of such Bonds of such Series over (y) the
Aggregate Imputed Principal Balance of the Bonds of such Series, calculated at
the time of such declaration, shall, subject to Section 5.3 hereof, become
immediately due and payable.

         (B)     Except to the extent specified otherwise in the Series
Supplement relating to any Series of Bonds, the Holders of Junior Bonds of such
Series shall have no right to exercise the rights referred to in clause (A)
above until the Class Imputed Principal Balance of each Class of the Senior
Bonds of such Series has been reduced to zero.  If any date on or after the
date on which the Class Imputed Principal Balance of each Class of the Senior
Bonds of a Series has been reduced to zero, an Event of Default occurs and is
continuing with respect to such Series, then and in every such case the Holders
of the Highest Priority Junior Class of such Series representing not less than
66 2/3% of the Aggregate Current Principal Amount of such Class may declare all
the Bonds of that Series to be immediately due and payable, by notice in
writing to the Issuer and the Trustee, in which event the outstanding Bonds of
such Series shall be accelerated in the same manner and with the same effect as
provided in clause (A) above.

         (C)     Except to the extent specified otherwise in the Series
Supplement relating to any Series of Bonds, at any time after such a
declaration of acceleration of maturity of the Bonds of a Series has been made
and before a judgment or decree for payment of the money due has been obtained
by the Trustee as hereinafter in this Article provided, the Holders of Bonds
representing 100% of the Aggregate Current Principal Amount of the Outstanding
Senior Bonds of such Series (if such declaration is made pursuant to clause (A)
above), or the Holders of the Highest Priority Junior Class of such Series
representing not less than 66 2/3% of such Class (if such declaration is made
pursuant to clause (B) above), by written notice to the Issuer and the Trustee,
may rescind and annul such declaration and its consequences if

                 (1)      the Issuer delivered to the Trustee a
         Non-Disqualification Opinion regarding the actions described in this
         subsection, if one or more REMIC elections has or have been made in
         respect of the assets securing the Series, and the Issuer has paid or
         deposited with the Trustee a sum sufficient to pay

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

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

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





                                      -74-

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


         Section 5.3      Proceedings.

         Subject to the provisions of Section 3.1 and the following sentence,
if an Event of Default occurs and is continuing with respect to a Series, the
Trustee may in its discretion proceed to protect and enforce its rights and the
rights of the Bondholders by such appropriate Proceedings as the Trustee shall
deem most effective 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 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 Series of 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 Trustee or any Bondholder against the Issuer.


         Section 5.4      Remedies.

         If an Event of Default shall have occurred and be continuing in
respect to a Series of Bonds and the Bonds of such Series have been declared
due and payable and such declaration and its consequences have not been
rescinded and annulled, the Trustee may do one or more of the following:

                 (a)      institute Proceedings for the collection of all
         amounts then payable on the Bonds of that Series, or under this
         Indenture in respect to that Series of Bonds, whether by declaration
         or otherwise, enforce any judgment obtained and collect from the
         Issuer (other than from the Trust Estate or other assets securing any
         other Series of Bonds) moneys adjudged due;

                 (b)      in accordance with Section 5.17, sell the Trust
         Estate and other assets, if any, securing the Bonds of that Series 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 securing the Bonds of that Series; and

                 (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





                                      -75-
<PAGE>   78
         Trustee or the Holders of the Bonds hereunder, including, without
         limitation, any action specified in the Series Supplement for any
         Series of Bonds.


         Section 5.5      [Reserved].


         Section 5.6      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
Trustee (irrespective of whether the Bonds of any Series shall then be due and
payable as therein expressed or by declaration or otherwise and irrespective of
whether the 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 of
         each Series issued hereunder and to file such other papers or
         documents as may be necessary or advisable in order to have the claims
         of the Trustee (including any claim for the reasonable compensation,
         expenses, disbursements and advances of the 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 Trustee and, in the event that the
Trustee shall consent to the making of such payments directly to the
Bondholders, to pay to the Trustee any amount due to it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, and any other amounts due the Trustee under Section 6.7.

         Nothing herein contained shall be deemed to authorize the 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 Trustee to vote
in respect of the claim of any Bondholder in any such Proceeding.

         Section 5.7      Trustee May Enforce Claims without Possession of 
Bonds.





                                      -76-
<PAGE>   79
         All rights of action and claims under this Indenture or any of the
Bonds may be prosecuted and enforced by the 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 Trustee shall be brought in its own
name as trustee of an express trust, and any recovery of judgment shall be, in
accordance with Section 5.8, for the payment of the reasonable compensation,
expenses, disbursements and advances of  the Trustee, its agents and counsel
and, except to the extent specified otherwise in the Series Supplement for any
Series of Bonds, for the ratable benefit of the Holders of the Bonds of the
Series in respect of which such judgment has been recovered.


         Section 5.8      Application of Money Collected.

         If the Bonds of a Series 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 Trustee with respect to such
Series of Bonds pursuant to this Article or otherwise and any monies that may
then be held or thereafter received by the Trustee with respect to such Series
of Bonds shall be applied in the following order, at the date or dates fixed by
the Trustee and, in case of the distribution of the entire amount due on
account of principal of, and interest on, such Bonds, upon presentation and
surrender thereof:

                 First:  To the payment of all amounts due the Trustee under
         Section 6.7;

                 Second: Except to the extent specified otherwise in the Series
         Supplement for any Series of Bonds, to the payment of amounts then due
         and unpaid upon the Outstanding Bonds of such Series for:

                 each Class of Bonds Outstanding that is due and unpaid as of
                 the Interest Payment Date most recently preceding date of any
                 declaration made pursuant to Section 5.2(A), together with any
                 Unpaid Interest outstanding as of such date of declaration,
                 such amount to be paid ratably among the Bonds of such Series
                 without preference or priority of any kind

                          (b)     interest on the Class Imputed Principal
                 Balance of each Class of Bonds (including interest on any
                 Class of Compound Interest Bonds) of such Series then
                 Outstanding at the Bond Interest Rate applicable thereto, for
                 the period from the end of the Interest Accrual Period with
                 respect to the Interest Payment Date most recently preceding
                 the date of any declaration made pursuant to Section 5.2(A),
                 to the date specified for such Class in the related Series
                 Supplement, (less such Class' share of the Net Interest
                 Shortfalls and the interest portion of any Realized Losses
                 incurred during the aforesaid accrual period on the mortgage
                 loans underlying the Conventional Certificates securing such
                 Series), such amount to be paid ratably among the Bonds of
                 such Series, without preference or priority of any kind;

<PAGE>   80
                 Third:  Except to the extent specified otherwise in the Series
         Supplement for any Series of Bonds, to the payment of the Aggregate
         Imputed Principal Balance of the Bonds of such Series, the Imputed
         Principal Balance of each Bond of such Series ratably, without
         preference or priority of any kind;

                 Fourth:  Except to the extent specified in the Series
         Supplement for any Series of Bonds, to the payment of the excess of
         (a) the Aggregate Current Principal Amount of the Bonds of such Series
         over (b) the Aggregate Imputed Principal Balance of such Bonds,  each
         such Bond's respective share of such excess amount, ratably, without
         preference or priority of any kind; and

                 Fifth:  Except as otherwise provided in the related Series
         Supplement, to the payment of the remainder, if any, (i) to the Issuer
         or any other Person legally entitled thereto if one or more REMIC
         elections has or have not been made in respect of the assets securing
         the Bonds of such Series or (ii) if such an election or elections has
         or have been or will be made, to the  Residual Interest in the REMIC
         that  includes such assets, as stipulated in the related Series
         Supplement.

         Section 5.9      Limitation on Suits.

         No Holder of a Bond of any Series 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 Trustee of a continuing Event of Default with respect to such
         Series;

                 (2)      (a) all of the Holders of the Classes of Senior Bonds
         of such Series having Class Imputed Principal Balances greater than
         zero or (b) in the event that no Class of Senior Bonds of such Series
         has a Class Imputed Principal Balance greater than zero, the Holders
         of the Highest Priority Junior Class of such Series representing not
         less than 66 2/3% of the Aggregate Current Principal Amount of such
         Class shall have made written request to the Trustee to institute
         Proceedings in respect of such Event of Default in its own name as
         Trustee hereunder;

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

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





                                      -78-
<PAGE>   81
                 (5)      no direction inconsistent with such written requests
         has been given to the Trustee during such 60-day period by (a) any
         Holder of a Class of Senior Bonds of such Series having Class Imputed
         Principal Balances greater than zero or (b) in the event that no Class
         of Senior Bonds of such Series has a Class Imputed Principal Balance
         greater than zero, any Holder of the Highest Priority Junior Class of
         such Series;

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 Series, except to the extent specified otherwise
in the Series Supplement for any Series.

         Section 5.10     Restoration of Rights and Remedies.

         If the 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 Trustee or to such Bondholder, then and in every such case the Issuer, the
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 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 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 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 Trustee or to the Bondholders may be exercised from time to time, and as
often as may be deemed expedient, by the Trustee or by the Bondholders, as the
case may be.





                                      -79-

         Section 5.13     Control by Bondholders.

         If an Event of Default is declared by or at the direction of the
Holders of Senior Bonds of a Series pursuant to Section 5.2(A) above, the
Holders of Bonds representing more than 50% of the Aggregate Current Principal
Amount of the Outstanding Senior Bonds of such  Series shall have the right to
direct the time, method and place of conducting any Proceeding for any remedy
available to the Trustee with respect to such Series or exercising any trust or
power conferred on the Trustee with respect to such Series.  If an Event of
Default is declared by or at the direction of the Holders of the Highest
Priority Junior Class of a Series pursuant to Section 5.2(B) above (and subject
to the conditions therein contained), the Holders of the Highest Priority
Junior Class of such Series representing more than 50% of the Aggregate Current
Principal Amount of such Class shall have the right to direct the time, method
and place of conducting any Proceeding for any remedy available to the Trustee
with respect to such Series or exercising any trust or power conferred on the
Trustee.  Any direction given by the Holders of Senior Bonds or Junior Bonds
pursuant to this Section 5.13 shall be subject to the following conditions:

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

                 (2)      any direction to the Trustee to undertake a Sale of a
         Trust Estate shall be by the Holders of Bonds secured thereby
         representing the percentage of the Aggregate Current Principal Amount
         of the Outstanding Bonds specified in Section 5.17(b)(1), unless
         Section 5.17(b)(2) is applicable, or except to the extent specified
         otherwise in the Series Supplement for any Series of Bonds,

                 (3)      the Trustee may take any other action deemed proper
         by the Trustee which is not inconsistent with such direction;
         provided, however, that, subject to Section 6.1, the Trustee need not
         take any action which it determines might involve it in liability or
         be unjustly prejudicial to the Bondholders not consenting.

         Section 5.14     Waiver of Past Defaults.

         (a)     Except to the extent specified otherwise in the Series
Supplement for any Series of Bonds, the Holders of Bonds representing 100% of
the Aggregate Current Principal Amount of the Outstanding Senior Bonds of a
Series may on behalf of the Holders of all the Bonds of such Series waive any
past Default hereunder with respect to such Series and its consequences, except
a Default in the payment of any installment of principal of, or interest on,
any Bond of that Series.

         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.





                                      -80-
<PAGE>   83
         (b)     Except to the extent specified otherwise in the Series
Supplement for any Series of Bonds, the Holders of the Highest Priority Junior
Class of such  Series representing not less than 66 2/3% of the Aggregate
Current Principal Amount of such Class may on behalf of all the Junior Bonds of
such Series waive any past Default hereunder in respect of which such Holders
would have been entitled to exercise their rights pursuant to Section 5.2(B),
and may waive the consequences of such Default, except, in either case, a
Default

                 (1)      in the payment of any installment of principal of, or
         interest on, any Bond of that Series, or

                 (2)      in respect of a covenant or provision hereof which
         under Section 9.2 cannot be modified or amended without the consent of
         each Outstanding Junior 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 Trustee for any action taken,
suffered or omitted by it as 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
Trustee, except to the extent specified otherwise in the Series Supplement
relating to any Series of Bonds, to any suit instituted by any Bondholder, or
group of Bondholders, holding in the aggregate Bonds representing more than 10%
of the Aggregate Current Principal Amount of the Outstanding Bonds of a Series,
or to any suit instituted by any Bondholder for the enforcement of the payment
of any installment of interest on any Bond on or after the Stated Maturity
thereof expressed in such Bond or for the enforcement of the payment of the
entire remaining unpaid principal amount of any Bond on or after the Stated
Maturity of the final installment of the principal thereof (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 law wherever
enacted, now or at any time hereafter in force, which may affect the covenants
in, or the performance of, this Indenture; and the Issuer (to the extent that
it may lawfully





                                      -81-
<PAGE>   84
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 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 a Trust Estate pursuant to Section 5.4 shall not be
         exhausted by any one or more Sales as to any portion of such Trust
         Estate remaining unsold, but shall continue unimpaired until the
         entire such Trust Estate shall have been sold or all amounts payable
         on the Bonds of the Series secured thereby and under this Indenture
         with respect thereto shall have been paid.  The Trustee may from time
         to time postpone any public Sale by public announcement made at the
         time and place of such Sale.  The Trustee hereby expressly waives its
         right to any amount fixed by law as compensation for any Sale.

                 (b)      To the extent permitted by law, and except as
         specified otherwise in the Series Supplement for any Series of Bonds,
         the Trustee shall not in any private Sale sell or otherwise dispose of
         the Trust Estate, or any portion thereof, securing a Series of Bonds
         which has been declared due and payable unless

                          (1)     if such Sale is effected consequent on a
                 declaration made by the Holders of Senior Bonds of a Series
                 pursuant to Section 5.2(A), the Holders of all Outstanding
                 Senior Bonds of such Series consent to, or direct the Trustee
                 to make, such Sale, or, if such Sale is effected consequent on
                 a declaration made by the Holders of the Highest Priority
                 Junior Class of such Series representing not less than 66 2/3%
                 of the Aggregate Current Principal of such Class pursuant to
                 Section 5.2(B), the Holders of the Highest Priority Junior
                 Class of such Series representing not less than 66 2/3% of the
                 Aggregate Current Principal of such Class consent to, or
                 direct the Trustee to make, such a Sale, or

                          (2)     the proceeds of such Sale would be not less
                 than the entire amount which would be distributable to the
                 Holders of the Senior Bonds or the Junior Bonds, as the case
                 may be, of such Series, in full payment thereof in accordance
                 with Section 5.8.

         The foregoing provisions shall not preclude or limit the ability of
         the Trustee to purchase all or any portion of the Trust Estate at a
         private Sale, provided that, unless otherwise specified in the related
         Series Supplement, in no event (except as may be compelled or required
         by applicable law or court order in which case the provisions of
         Section 4.3 shall apply if appropriate) shall the Trustee purchase or
         sell the Trust Estate or any portion thereof (if an election or
         elections has or have been made or will be made to treat the Trust
         Estate or such other assets specified in such election securing the
         Series as a REMIC) unless it either (i) has





                                      -82-
<PAGE>   85
         received a Non-Disqualification Opinion, or (ii) the proceeds of such
         Sale net of any tax on "prohibited transactions" as defined in Section
         860F of the Code that is payable from the Trust Estate would be not
         less than the entire amount that would be distributable to the Holders
         of the Bonds, in full payment thereof in accordance with Section 5.8,
         and such sale meets the requirements of Section 4.3.

                 (c)      Except as otherwise provided in the related Series
         Supplement, unless the Holders of all Outstanding Bonds have otherwise
         consented or directed the Trustee, at any public Sale of all or any
         portion of a 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 and the amount of any tax on "prohibited transactions" as
         defined in Section 860F of the Code that would be payable from the
         Trust Estate if an election or elections has or have been  made or
         will be made to treat the Trust Estate or such other assets specified
         in such election securing the Series as a REMIC, has not been
         established by the Trustee and no Person bids an amount equal to or
         greater than such amount, the Trustee shall bid an amount at least
         $1.00 more than the highest other bid.

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

                          (1)     any Holder or Holders of Bonds of the Series
                 secured thereby may bid for and purchase the property offered
                 for Sale, and upon compliance with the terms of such 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 of such Series or
                 claims for interest thereon in lieu of cash up to the amount
                 which 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; for the
                 purposes of this clause (1), the principal amount of
                 indebtedness of the Issuer evidenced by any Outstanding Bond
                 delivered in lieu of cash shall be the Imputed Principal
                 Balance of such Bond.

                          (2)     the 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 which would be
                 distributable to the Holders of the Bonds of the Series
                 secured thereby as a result of such Sale in accordance with
                 Section 5.8 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 of such Series
                 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 Trustee shall be held and dealt with by it
                 in accordance with the provisions of this Indenture;

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

                          (4)     the Trustee is hereby irrevocably appointed
                 the agent and attorney-in-fact of the Issuer to transfer and
                 convey its interest in any portion of such 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 Trustee's authority, inquire
                 into the satisfaction of any conditions precedent or see to
                 the application of any moneys.

                 (e)      Notwithstanding anything in this Indenture to the
         contrary, if an Event of Default specified in Section 5.1(A)(1) is the
         Event of Default, or one of the Events of Default, on the basis of
         which the Bonds of a Series have been declared due and payable, then
         the Trustee may, in its sole discretion, sell the Trust Estate
         securing such Series without compliance with this Section 5.17, but
         except as otherwise provided in the related Series Supplement, subject
         to and in compliance with Section 4.3.

         Section 5.18     Action on Bonds.

         The Trustee's right to seek and recover judgment on a Series of Bonds
or 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 Trustee or
the Holders of Bonds of any Series shall be impaired by the recovery of any
judgment by the Trustee against the Issuer or by the levy of any execution
under such judgment upon any portion of the Trust Estate securing such Series.


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

         Except to the extent provided otherwise in the related Series
Supplement, the Trust Estate Granted to the Trustee as security for a
particular Series will serve as security only for that Series.  Except to the
extent provided otherwise in the related Series Supplement, Holders of Bonds of
one Series shall have no recourse against the Trust Estate Granted to the
Trustee as security for any other Series, and no judgment against the Issuer
for any amount due with respect to one Series of 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 TIA.

                 (a)      Pursuant to Section 3.16(a) of the TIA, all
         provisions automatically provided for in Section 3.16(a) are hereby
         expressly excluded.

                 (b)      Section 3.16(b) of the TIA requires the following
         provision to be included herein:

                          Notwithstanding any other provision of the indenture
                 to be qualified, the right of any holder of any indenture
                 security to receive payment of the principal of and interest
                 on such indenture security, on or after the respective due
                 dates expressed in such indenture security, or to institute
                 suit for the enforcement of any such payment on or after such
                 respective dates, shall not be impaired or affected without
                 the consent of such holder, except as to a postponement of an
                 interest payment consented to as provided in paragraph (2) of
                 subsection (a), and except that such indenture may contain
                 provisions limiting or denying the right of any such holder to
                 institute any such suit, if and to the extent that the
                 institution or prosecution thereof or the entry of judgment
                 therein would, under applicable law, result in the surrender,
                 impairment, waiver, or loss of the lien of such indenture upon
                 any property subject to such lien.

                                   ARTICLE VI



                                  THE TRUSTEE


         Section 6.1      Duties of Trustee.

                 (a)      The Trustee shall be subject to TIA Section 315(c).

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

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

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

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

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

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

                          (3)     The 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
                 5.4 or Section 5.17.

                 (d)      For all other purposes under this Indenture, the
         Trustee shall not be deemed to have notice of any Event of Default
         described in Section 5.1(A)(2), 5.1(A)(5) or 5.1(A)(6) or any default
         (other than a default in payment to the Trustee) under any Pooling and
         Administration Agreement or any Guaranty Agreement unless a
         Responsible Officer assigned to and working in the Trustee's corporate
         trust department has actual knowledge thereof or unless written notice
         of any event which is in fact such an Event of Default or





                                      -86-
<PAGE>   89
         Default is received by the Trustee at the Corporate Trust Office, and
         such notice references the Bonds generally, the Bonds of any Series,
         the Issuer, any Trust Estate or this Indenture.

                 (e)      No provision of this Indenture shall require the
         Trustee to expend or risk its own funds or otherwise incur any
         financial liability in the performance of any of its duties hereunder,
         or in the exercise of any of its rights or powers, if it shall have
         reasonable grounds for believing that repayment of such funds or
         adequate indemnity against such risk or liability is not reasonably
         assured to it; provided, however, that the Trustee shall not refuse or
         fail to perform any of its duties hereunder solely as a result of
         nonpayment of its normal fees and expenses and further provided that
         nothing in this Section 6.1(e) shall be construed to limit the
         exercise by the Trustee of any right or remedy permitted under this
         Indenture or otherwise in the event of the Issuer's failure to pay the
         Trustee's fees and expenses pursuant to Section 6.7.  In determining
         that such repayment or indemnity is not reasonably assured to it, the
         Trustee must consider not only the likelihood of repayment or
         indemnity by or on behalf of the Issuer but also the likelihood of
         repayment or indemnity from amounts payable to it from the applicable
         Trust Estate pursuant to Sections 6.7 and 8.2(d).

                 (f)      Every provision of this Indenture that in any way
         relates to the 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 Trustee or otherwise, the rights, powers and
         duties of the Trustee with respect to the Trust Estate (or the
         proceeds thereof) and the Holders of the Bonds and the rights of the
         Bondholders shall, to the extent permitted by law, continue to be
         governed by the terms of this Indenture.

         Section 6.2      Notice of Default.

         Within 90 days after the occurrence of any Default known to the
Trustee, the Trustee shall transmit by mail to all Holders of Bonds of each
Series as to which such Default has occurred notice of each such Default,
unless such Default shall have been cured or waived, provided, however, that
except in the case of a Default of the type described in Section 5.1(A)(1), the
Trustee shall be protected in withholding such notice if and so long as the
board of directors, the executive committee or a trust committee of directors
and/or Responsible Officers of the Trustee in good faith determine that the
withholding of such notice is in the interests of the Holders of the Bonds of
the Series affected by such Default.

         Section 6.3      Rights of Trustee.

                 (a)      The Trustee may rely on any document believed by it
         to be genuine and to have been signed or presented by the proper
         Person.  The Trustee need not investigate any fact or matter stated in
         the document.

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

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

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

         Section 6.4      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 Trustee assumes no responsibility for their correctness.
The Trustee makes no representations with respect to any Trust Estate or as to
the validity or sufficiency of this Indenture or of the Bonds.  The Trustee
shall not be accountable for the use or application by the Issuer of Bonds or
the proceeds thereof or any money paid to the Issuer or upon Issuer Order
pursuant to the provisions hereof.


         Section 6.5      May Hold Bonds.

         The 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 6.8 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
Trustee, Agent, or such other agent.


         Section 6.6      Money Held in Trust.

         Money held by the Trustee in trust hereunder need not be segregated
from other funds except to the extent required by this Indenture or by law, but
shall be accounted for separately for each Series.  The 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 which are obligations of the Trustee, in its commercial
capacity, and income or other gain actually received by the Trustee on
investments, which are obligations of others.

         Section 6.7      Compensation and Reimbursement.

         (a)     The Issuer agrees

                 (1)      subject to any separate written agreement with the
         Trustee, to pay the Trustee from time to time reasonable compensation
         for all services rendered by it hereunder (which compensation shall
         not be limited by any provision of law in regard to the compensation
         of a trustee of an express trust);

                 (2)      except as otherwise expressly provided herein, to
         reimburse the Trustee upon its request for all reasonable expenses,
         disbursements and advances incurred or made by the Trustee in
         accordance with any provision of this Indenture (including the
         reasonable compensation and the expenses and disbursements of its
         agents and counsel), except any such expense, disbursement or advance
         as may be attributable to its negligence or bad faith; and

                 (3)      to indemnify the Trustee and its agents for, and to
         hold them harmless against, any loss, liability or expense incurred
         without negligence or bad faith on their part, arising out of, or in
         connection with, the acceptance or administration of this trust,
         including the costs and expenses of defending themselves against any
         claim in connection with the exercise or performance of any of their
         powers or duties hereunder, provided that:

                           (i)    with respect to any such claim, the Trustee
                 shall have given the Issuer written notice thereof promptly
                 after the Trustee shall have knowledge thereof;

                          (ii)    while maintaining absolute control over its
                 own defense, the Trustee shall cooperate and consult fully
                 with the Issuer in preparing such defense; and

                         (iii)    notwithstanding anything to the contrary in
                 this Section 6.7(a)(3), the Issuer shall not be liable for
                 settlement of any such claim by the Trustee entered into
                 without the prior consent of the Issuer.

         Subject to Section 6.10, the Trustee agrees to fully perform its
duties under this Indenture notwithstanding any failure on the part of the
Issuer to make any payments, reimbursements or indemnifications to the Trustee
pursuant to this Section 6.7.

         (b)     The Issuer may remit payment for such fees and expenses to the
Trustee or, in the absence thereof, the Trustee may reimburse itself from time
to time pursuant to Section 8.2(d) hereof for payments of its fees and expenses
hereunder from moneys on deposit in the Collection Account.

         (c)     Notwithstanding the provisions of Section 6.1(e) and
6.7(a)(1), (2) and (3) hereof, the fees, expenses, disbursements and advances
payable to the Trustee pursuant to Section 6.7(a)(1) and





                                      -89-
<PAGE>   92
(2) and any indemnity payments due to the Trustee pursuant to Section 6.7(a)(3)
shall not in the aggregate on any Payment Date exceed the Expense Reserve
Amount, if any; provided, however, that the Trustee shall advance any amounts
in excess thereof due under this Section 6.7.

         (d)     If the Bonds have been declared due and payable following an
Event of Default pursuant to Section 5.2, which acceleration of Maturity and
its consequences have not been rescinded and annulled and moneys collected by
the Trustee are being applied in accordance with Section 5.8 as may be amended
by any Series Supplement, expenses, disbursements and advances due the Trustee
under 6.7(a)(2) and indemnity payments due to the Trustee under Section
6.7(a)(3) hereof shall no longer be subject to the provisions of Section
6.7(c).

         (e)     As security for the payment obligations of the Issuer pursuant
to the foregoing provisions of this Section 6.7, the Issuer hereby Grants to
the Trustee a lien ranking at all times senior to the lien of the Bonds with
respect to which any claim of the Trustee under this Section arose and senior
to all other liens, if any, upon all property and funds held or collected as
part of the Trust Estate for such Bonds by the Trustee in its capacity as such.
The Trustee shall not (i) exercise or enforce such senior lien in any manner,
or (ii) institute any Proceeding against the Issuer for any payments,
reimbursements, or indemnifications to the Trustee or to enforce such lien, in
either case unless (i) the Bonds have been declared due and payable following
an Event of Default pursuant to Section 5.2, (ii) such acceleration of Maturity
and its consequences have not been rescinded and annulled, and (iii) moneys
collected by the Trustee are being applied in accordance with Section 5.8, as
may be amended by any Series Supplement.

         (f)     Subject to the last sentence of Section 6.7(e), nothing in
this Section 6.7 shall be construed to limit (except as otherwise expressly
provided in subsection (e) of this Section 6.7) the exercise by the Trustee of
any right or remedy permitted under the Indenture or otherwise in the event of
the Issuer's failure to pay the amounts due the Trustee pursuant to this
Section 6.7.

         Section 6.8      Disqualification; Conflicting Interests.

         In addition to the conflicting interests specified in TIA Section
310(b), the Trustee shall be deemed to have a conflicting interest under said
Section  310(b) upon the occurrence of a default, if by reason of supplements
or amendments to this Indenture as originally executed there shall be created
covenants, restrictions, conditions or additional events of default which

                 (1)      unless otherwise provided in the related Series
         Supplement, would give the Holders of Bonds of any Series any rights
         with respect to the Trust Estate or any other property held by the
         Trustee for the benefit of Holders of Bonds of any other Series with
         respect to which it is also serving as Trustee, or

                 (2)      is sufficiently likely to involve a material conflict
         of interest between Series of Bonds that it is advisable in the public
         interest or for the protection of Holders of Bonds





                                      -90-
<PAGE>   93
         of any Series that the Trustee disqualify itself from acting as such
         with respect to one or more applicable Series of Bonds.

         Section 6.9      Eligibility; Trustee's Capital and Surplus.

         The Trustee shall at all times meet the then current capital and
surplus requirements of the TIA and shall have a combined capital and surplus
of at least $50,000,000 or be a member or subsidiary of a bank holding system,
the aggregate combined capital and surplus of which is at least $50,000,000. If
the Trustee or the members of the bank holding company system of which it is a
part publish annual reports of condition of the type described in TIA Section
310(a)(2), its (or such bank holding company system's) combined capital and
surplus for purposes of TIA Section 310(a)(2) shall be as set forth in the
latest such report or reports.  If at any time the Trustee shall cease to be
eligible in accordance with the provisions of TIA Section  310(a)(2), it shall
resign immediately in the manner and with the effect hereinafter specified in
this Article.


         Section 6.10     Resignation and Removal; Appointment of Successor.

                 (a)      Subject to the provisions of the Series Supplement
         with respect to any Series of Bonds, the Trustee may resign at any
         time with respect to the Bonds of one or more Series (or for fewer
         than all Classes within any such Series) by giving written notice
         thereof to the Issuer.  If an instrument of acceptance by a successor
         Trustee shall not have been delivered to the Trustee within 30 days
         after the giving of such notice of resignation, the resigning Trustee
         may petition any court of competent jurisdiction for the appointment
         of a successor Trustee.

                 (b)      The Trustee may be removed at any time with respect
         to any Series, or any Class within any Series, by Act of the Holders
         representing more than 50% of the Aggregate Current Principal Amount
         of the Outstanding Bonds of that Series, delivered to the Trustee and
         to the Issuer.

                 (c)      If at any time following a default:

                          (1)     the Trustee shall have a conflicting interest
                  under Section 6.8 and TIA Section 310(b) and shall fail to
                  resign or eliminate such conflicting interest in accordance
                  with TIA Section 310(b) after written request therefor by the
                  Issuer or by any Bondholder, or

                          (2)     the Trustee shall cease to be eligible under
                 Section 6.9 or shall become incapable of acting or shall be
                 adjudged a bankrupt or insolvent, or a receiver of the Trustee
                 or of its property shall be appointed, or any public officer
                 shall take charge or control of the Trustee or of its property
                 or affairs for the purpose of rehabilitation, conservation or
                 liquidation,





                                      -91-
<PAGE>   94
         then, in any such case, (i) the Issuer by a Board Resolution may
         remove the Trustee, and the Issuer shall join with the Trustee in the
         execution, delivery and performance of all instruments and agreements
         necessary or proper to appoint a successor Trustee and to vest in such
         successor 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
         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
         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 himself and all others similarly
         situated, petition any court of competent jurisdiction for the removal
         of the Trustee and the appointment of a successor Trustee.

                 (d)      If the Trustee shall resign, be removed or become
         incapable of acting, or if a vacancy shall occur in the office of the
         Trustee with respect to the Bonds of one or more Series, or any Class
         within such Series, for any cause, the Issuer by a Board Resolution
         shall promptly appoint a successor Trustee with respect to such Series
         or such Class.  If within one year after such resignation, removal or
         incapability or the occurrence of such vacancy a successor Trustee
         with respect to any Series shall be appointed by Act of the Holders of
         Bonds representing more than 50% of the Aggregate Current Principal
         Amount of the Outstanding Bonds of that Series delivered to the Issuer
         and the retiring Trustee, the successor Trustee so appointed shall,
         forthwith upon its acceptance of such appointment, become the
         successor Trustee and supersede the successor Trustee appointed by the
         Issuer.  If no successor 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 bona fide
         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 Trustee.

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

         Section 6.11     Acceptance of Appointment by Successor.

         Every successor Trustee appointed hereunder shall execute, acknowledge
and deliver to the Issuer and the retiring Trustee an instrument accepting such
appointment, and thereupon the resignation or removal of the retiring Trustee
shall become effective and such successor Trustee, without any further act,
deed or conveyance, shall become vested with all the rights, powers, trusts and
duties





                                      -92-
<PAGE>   95
of the retiring Trustee. Notwithstanding the foregoing, on request of the
Issuer or the successor Trustee, such retiring Trustee shall, execute and
deliver an instrument transferring to such successor Trustee all the rights,
powers and trusts of the retiring Trustee (provided, however, that if the
retiring Trustee has been removed or has resigned, pursuant to Section 6.10,
with respect to less than all Series for which it is Trustee, or for less than
all Classes within any such Series, then such transfer shall be limited to its
rights and powers with respect to each Series or Class with respect to which it
has resigned or been removed), and shall duly assign, transfer and deliver to
such successor Trustee all property and money held by such retiring Trustee
hereunder (provided, however, that if the retiring Trustee has been removed or
has resigned, pursuant to Section 6.10, with respect to less than all Series
for which it is Trustee, or for less than all Classes within any such Series,
then such assignment, transfer and delivery by the retiring Trustee shall be
limited to the property and money held by it for the benefit of the Holders of
Bonds of the Series or Class with respect to which it has resigned or been
removed); provided, however, that the execution and delivery of any such
instruments by the retiring Trustee and the succession of a new Trustee shall
not in any way (i) impair or release the liens of the retiring Trustee provided
for in Section 6.7, (ii) constitute a waiver of any charges due the retiring
Trustee under the Indenture, or (iii) constitute a waiver of any right of the
retiring Trustee to institute proceedings to enforce any rights or remedies
available to the retiring Trustee pursuant to this Indenture.  Upon request of
any such successor Trustee, the Issuer shall execute and deliver any and all
instruments for more fully and certainly vesting in and confirming to such
successor Trustee all such rights, powers and trusts.

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


         Section 6.12   Merger, Conversion, Consolidation or Succession to 
Business of Trustee.

         Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any
merger, conversion or consolidation to which the Trustee shall be a party, or
any corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the 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 Trustee then in office, any successor by merger,
conversion or consolidation to such authenticating Trustee may adopt such
authentication and deliver the Bonds so authenticated with the same effect as
if such successor Trustee had authenticated such Bonds.

        Section 6.13    Preferential Collection of Claims Against Issuer.

         The Trustee, and any co-trustee or separate trustee authorized in
Section 6.14,  shall be subject to TIA Section  311(a), excluding any creditor
relationship listed in TIA Section  311(b), and a Trustee,





                                      -93-
<PAGE>   96
co-trustee or separate trustee who has resigned or been removed shall be
subject to TIA Section  311(a) to the extent indicated.

         Section 6.14     Co-trustees and Separate 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 a Trust Estate
may at the time be located, or the requirements of the Series Supplement with
respect to any Series of Bonds, the Issuer and the Trustee shall have power to
appoint, and, upon the written request of the Trustee or of the Holders of
Bonds representing more than 50% of the Aggregate Current Principal Amount of
the Outstanding Bonds of the Series or Class, as the case may be, secured by
the Trust Estate with respect to which a co-trustee or separate trustee is
being appointed, the Issuer shall for such purpose join with the Trustee in the
execution, delivery and performance of all instruments and agreements necessary
or proper to appoint, one or more Persons approved by the Trustee either to act
as co-trustee, jointly with the Trustee, of all or any part of such 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 so to do, or in case an Event of Default has
occurred and is continuing, the Trustee alone shall have power to make such
appointment.

         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 Trustee hereunder, shall
         be exercised, solely by the Trustee.

                 (2)      The Trustee at any time, by an instrument in writing
         executed by it, with the concurrence of the Issuer evidenced by a
         Board Resolution, 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 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 Trustee, the Issuer shall join with
         the Trustee in the execution, delivery and performance of all
         instruments and agreements necessary or





                                      -94-
<PAGE>   97
         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.

                 (3)      No co-trustee or separate trustee hereunder shall be
         personally liable by reason of any act or omission of the Trustee, or
         any other such trustee hereunder, and the Trustee shall not be
         personally liable by reason of any act or omission of any co-trustee
         or other such separate trustee hereunder.

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

         Section 6.15     Authenticating Agents.

         Upon the request of the Issuer, the Trustee 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 of each Series
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 Trustee and such Authenticating Agent,
for notation on the Bonds of such Series of the authority of an Authenticating
Agent appointed after the initial authentication and delivery of such Bonds) in
connection with transfers and exchanges under Sections 2.6 and 2.7, as fully to
all intents and purposes as though the Authenticating Agent had been expressly
authorized by those Sections to authenticate and deliver Bonds of such Series.
Notwithstanding the foregoing, if an Authenticating Agent for a Series is
designated in the related Series Supplement, no separate request or appointment
shall be required.  For all purposes of this Indenture (other than in
connection with the authentication and delivery of Bonds pursuant to Sections
2.5 and 2.12 in connection with their initial issuance and for purposes of
Section 2.8), 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 Trustee."  Such Authenticating Agent shall at all
times be a Person that both meets the requirements of Section 6.9 for the
Trustee hereunder and has its principal office in the Borough of Manhattan,
City and State of New York.

         Any Authenticating Agent for a Series shall also serve as Bond
Registrar or co-Bond Registrar for such Series, as provided in Section 2.7.
Any Authenticating Agent appointed by the Trustee pursuant to the terms of this
Section 6.15 or pursuant to the terms of any Supplemental Indenture shall
deliver to the 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 Trustee for and holding the 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.






                                      -95-
<PAGE>   98
         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 Trustee and the Issuer.  The Trustee may at any
time terminate the agency of any Authenticating Agent by giving written notice
of termination to such Authenticating Agent and the Issuer.  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
Trustee shall promptly appoint a successor Authenticating Agent, shall give
written notice of such appointment to the Issuer and shall mail notice of such
appointment to all Holders of Bonds of the applicable Series.

         The Trustee agrees, subject to Section 6.1(e), to pay to any
Authenticating Agent from time to time reasonable compensation for its services
and the Trustee shall be entitled to be reimbursed for such payments, subject
to Section 6.7.  The provisions of Sections 2.10, 6.4 and 6.5 shall be
applicable to any Authenticating Agent.

         Section 6.16     Alternate Trustees.

         Whenever the Issuer shall so determine, a Person different than the
initial Trustee may be appointed by the Issuer to act as an alternate Trustee
with respect to any Series of Bonds proposed to be issued hereunder.  Such
alternate Trustee shall also satisfy the eligibility requirements of the TIA
and this Article VI.  The Issuer shall have the power to appoint a separate
Trustee to act as Trustee with respect to any Series of Bonds proposed to be
issued hereunder and each such alternate Trustee and the Issuer alone shall
have the power to execute and deliver an agreement supplemental hereto, which
agreement supplemental hereto may be the Series Supplement for such Series of
Bonds, which shall contain such provisions as shall be deemed necessary or
desirable to confirm that all the rights, powers, trust and duties of the
Trustee with respect to the Outstanding Bonds of any Series as to which the
Trustee initially named in the Series Supplement for such Series is not
retiring, shall continue to be vested in such initial Trustee, and shall add to
or change any of the provisions of this Indenture as shall be necessary to
provide for or facilitate the administration of the trust hereunder by more
than one Trustee with respect to the Outstanding Bonds of any Series as to
which the initial Trustee named herein is not to be the Trustee or with respect
to any proposed Series of Bonds, it being understood that nothing herein or in
such supplemental agreement shall constitute such Trustees as co-Trustees of
the same trust and that each such Trustee shall be a Trustee of a separate
trust or trusts with respect to different Series of Bonds each concurrently
Outstanding.  No separate or alternate Trustee shall accept its appointment
unless, at the time of such acceptance such separate Trustee shall be qualified
and eligible under this Article VI.

                         BONDHOLDERS' LISTS AND REPORTS


         Section 7.1      Issuer to Furnish Trustee Names and Addresses of 
Bondholders.

                 (a)      The Issuer will furnish or cause to be furnished to
         the Trustee (i) semi-annually, not less than 45 days nor more than 60
         days after each Interest Payment Date for a Series, a list, in such
         form as the Trustee may reasonably require, of the names and addresses
         of the Holders of Bonds of such Series, and (ii) at such other times,
         as the Trustee may request in writing, within 30 days after receipt by
         the Issuer of any such request, a list of similar form and content as
         of a date not more that 10 days prior to the time such list is
         furnished; provided, however, that so long as the Trustee is the Bond
         Registrar, no such list shall be required to be furnished.  If the
         Bonds of a particular Series have Interest Payment Dates which are
         more frequent than semi-annual, then the applicable Interest Payment
         Dates for purposes of clause (i) of the preceding sentence shall be
         the Interest Payment Date occurring closest to six months after the
         Closing Date for such Series and each Interest Payment Date occurring
         at six-month intervals thereafter.

                 (b)      In addition to furnishing to the Trustee the
         Bondholder lists, if any, required under subsection (a), the Issuer
         shall also furnish all Bondholder lists, if any, required under
         Section 3.3 at the times required by said Section 3.3.

         Section 7.2      Preservation of Information; Communications to 
Bondholders.

                 (a)      The Trustee shall preserve, in as current a form as
         is reasonably practicable, the names and addresses of the Holders of
         Bonds contained in the most recent list, if any, furnished to the
         Trustee as provided in Section 7.1 and the names and addresses of the
         Holders of Bonds received by the Trustee in its capacity as Bond
         Registrar.  The Trustee may destroy any list furnished to it as
         provided in Section 7.1 upon receipt of a new list so furnished.

                 (b)      The Issuer, the Trustee and the Bond Registrar shall
          have the protection of TIA Section 312(c).

         Section 7.3      Reports by Trustee.

                 (a)      In addition to any report required to be delivered by
         the Trustee to the Holders of Bonds of any Series pursuant to TIA
         Section  313(a), additional reports may be required to be delivered by
         the Trustee as set forth in the Series Supplement for any Series of
         Bonds.





                                      -97-
<PAGE>   100
                 (b)      For purposes of the information required to be
         included in any reports to be delivered by the Trustee pursuant to TIA
         Sections  313(a)(3), 313(b)(1) (if applicable), 313(b)(2), or pursuant
         to the Series Supplement for any Series of Bonds as may be required
         pursuant to Section 7.3(a), the principal amount of "indenture
         securities" outstanding on the date as of which such information is
         provided shall be the Aggregate Current Principal Amount of the then
         Outstanding Bonds of the particular Series covered by the report.

                 (c)      With respect to any report required to be delivered
         by the Trustee pursuant to TIA Section 313(a) or (b), or as otherwise
         required pursuant to Section 7.3(a), the Trustee shall mail any such
         report to all Holders of such Series of Bonds within 30 days after 
         May 15 of each year (the "reporting date"), commencing with the year 
         after the issuance of such Series of Bonds.

                 (d)      Unless provided otherwise in the Series Supplement
         for any Series of Bonds, upon written request in form satisfactory to
         the Trustee received by the Trustee at least fifteen days prior to the
         next Payment Date, the Trustee will provide notice to a Bondholder on
         such Payment Date of such Bondholder's priority status with respect to
         such Bondholder's requests for redemption pursuant to Section 10.4.

         Section 7.4      Reports by Issuer.

         The Issuer (a) shall file with the Trustee within 15 days after it
files them with the Commission copies of the annual reports and of the
information, documents, and other reports (or copies of such portions of any of
the foregoing as the Commission may by rules and regulations prescribe) which
the Issuer is required to file with the Commission pursuant to Section 13 or
15(d) of the Securities Exchange Act of 1934 and (b) shall also comply with the

           ACCOUNTS, PAYMENTS OF INTEREST AND PRINCIPAL, AND RELEASES


         Section 8.1      Collection of Moneys.

         Except as otherwise expressly provided herein, the 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 Trustee pursuant to this
Indenture.  The Trustee shall hold all such money and property received by it
as part of the Trust Estate with respect to which it was received, and shall
apply it as provided in this Indenture.  If the Trustee shall not have received
a Distribution with respect to any Certificate by the Business Day immediately
following the related Distribution Date, the Trustee shall, unless the Issuer
shall have made provisions satisfactory to the Trustee for delivery to the
Trustee of an amount equal to such Distribution, request the issuer or
guarantor of such Certificate, as appropriate, to make such payment as promptly
as practicable or legally permitted.  If the Trustee shall subsequently receive
any such Distribution, it may withdraw such request.  Notwithstanding any other
provision hereof, the Trustee shall deliver to the Issuer or its designee or
assignee any Distribution received with respect to a Certificate after the
related Distribution Date to the extent that the Issuer previously made payment
or provision for payment with respect to such Distribution in accordance with
this Section 8.1, and any such Distribution shall not be deemed part of the
Trust Estate for the related Series.

         Except as otherwise expressly provided in this Indenture, if,
following any request by the Trustee for payment of a late Distribution, any
default occurs in the making of such payment, or if a default occurs in any
other performance required under any Certificate with respect to any Series,
the Trustee may, and upon the request of the Holders of Bonds representing more
than 50% of the Aggregate Current Principal Amount of the Outstanding Bonds of
the affected Series shall, take such action as may be appropriate to enforce
such payment or performance including the institution and prosecution of
appropriate Proceedings.  Any such action shall be without prejudice to any
right to claim a Default or Event of Default with respect to such Series under
this Indenture and to proceed thereafter as provided in Article V.


         Section 8.2      Collection Accounts.

                 (a)      On or before the Closing Date for a Series, the
         Issuer shall open, at the Corporate Trust Office, one or more accounts
         (each of which shall be an Eligible Account) which shall collectively
         be the "Collection Account" for such Series.  The Trustee shall
         promptly deposit in the related Collection Account all Distributions
         received by it with respect to Certificates securing the Bonds of a
         Series (other than Distributions required to be delivered to the
         Issuer pursuant to Section 8.1).  All Distributions deposited from
         time to





                                      -99-
<PAGE>   102
         time in a Collection Account, any amount required to be deposited in
         the Collection Account for a Series pursuant to Section 2.12(g) and
         the terms of the related Series Supplement, all other deposits therein
         pursuant to this Indenture, and all investments made with such moneys,
         including all income or other gain from such investments, shall be
         held by the Trustee in such Collection Account as part of the Trust
         Estate for the related Series as herein provided, subject to
         withdrawal by the Trustee for the purposes set forth in subsections
         (c) and (d) of this Section 8.2.  All funds withdrawn from a
         Collection Account pursuant to subsection (c) of this Section 8.2 for
         the purpose of making payments to the Holders of Bonds of the related
         Series shall be applied in accordance with Section 3.3.

                 (b)      So long as no Default or Event of Default shall have
         occurred and be continuing with respect to a Series of Bonds, all or a
         portion of the related Collection Account shall be invested and
         reinvested by the Trustee at the Issuer's direction or pursuant to the
         provisions of the related Series Supplement in one or more Eligible
         Investments bearing interest or sold at discount. No such investment
         shall mature later than the Business Day immediately preceding the
         next Principal Reduction Date for such Series unless permitted
         otherwise by the Rating Agencies.

                 Notwithstanding the foregoing,

                       (i)        except as permitted by clause (ii) below, no
                 investment of any amount held in a Collection Account may
                 mature later than the Business Day immediately preceding the
                 next Payment Date for Bonds of the related Series unless
                 permitted otherwise by the Rating Agencies,

                      (ii)        any investment (including repurchase
                 agreements) on which the Trustee (or any agent of the Trustee
                 acceptable to the Rating Agency or Agencies that rated such
                 Series) is the obligor, may mature on a Payment Date or
                 Special Payment Date if, under this Section 8.2, such
                 investment could otherwise mature on the Business Day
                 immediately preceding such Payment Date or Special Payment
                 Date and

                      (iii)       if there are any Overdue Bonds of a
                 Series Outstanding, funds then in the related Collection
                 Account may be invested in investments maturing later than the
                 Business Day immediately preceding the next Special Payment
                 Date, unless permitted otherwise by the Rating Agencies, only
                 to the extent that after giving effect to such proposed
                 investment the amount of funds that would be on deposit in the
                 Collection Account (including therein the amount of
                 Distributions and proceeds of investments scheduled to be
                 deposited in such Collection Account prior to such next
                 Special Payment Date) and would be available to make payments
                 on the Bonds of such Series on such next Special Payment Date,
                 exceeds any payments of principal

                 of or interest on any Overdue Bonds of such Series due and
                 payable on such next Special Payment Date.

                 All income or other gains from investment of moneys deposited
         in a Collection Account shall be deposited by the Trustee in such
         Collection Account immediately upon receipt, and any loss resulting
         from such investment shall be charged to such Collection Account.

                 (c)      Unless the Bonds of a Series have been declared due
         and payable pursuant to Section 5.2 and moneys collected by the
         Trustee with respect to such Series are being applied in accordance
         with Section 5.8, amounts on deposit in the related Collection Account
         on any Payment Date or Special Payment Date shall be withdrawn from
         such Collection Account, in the amounts required, for application as
         follows:

                       (i)        on any Special Payment Date, except to the
                 extent provided otherwise in the applicable Series Supplement
                 and to the extent permitted by applicable law,

                                  first, to the payment of all interest due
                              with respect to any Overdue Bonds of such Series
                              called for redemption, pro rata without any
                              preference or priority as to Maturity, and

                                  second, to the payment of amounts due with
                              respect to principal of such Overdue Bonds
                              (including any portion of an installment of
                              principal required to be paid which was not paid
                              therefor, and any amounts remaining unpaid on
                              Bonds with respect to which the Redemption Price
                              was not paid in full on the applicable Redemption
                              Date), in the order in which such amounts became
                              due and pro rata among all amounts which became
                              due on the same date, each such amount being the
                              amount thereof set forth in the applicable
                              Special Payment Date Statement; and

                      (ii)        on any Payment Date, in accordance with the
                 order of priority of payment specified in the related Series
                 Supplement;

         each such amount being the amount thereof set forth in the applicable
         Special Payment Date Statement or Payment Date Statement, as the case
         may be.

                 (d)      On or after each Payment Date for a Series, so long
         as the Trustee shall have prepared a Payment Date Statement in respect
         of such Payment Date and shall have made, or, in accordance with
         Section 3.3, set aside from amounts in the Collection Account for such
         Series an amount sufficient to make the payment of principal of and
         interest on the Bonds of such Series then required to be made as
         indicated in such Payment Date Statement, the cash balance, if any,
         then remaining in the related Collection Account, less the amount of





                                     -101-

         Distributions due on the related Certificates but not received on the
         immediately preceding Distribution Date and the amount of any
         Reinvestment Income then payable to the Bond Manager, shall be
         withdrawn from such Collection Account by the Trustee and applied

                          first, to the payment of any unpaid amount due the 
                 Trustee pursuant to Section 6.7,

                          second, to the payment of any unpaid amount due any
                 firm of Independent Accountants pursuant to Section 8.9(a),

                          third, to the extent required by the related Series
                 Supplement, to deposit an amount in the related Expense Fund
                 (any amount so deposited being released from the lien of the
                 Indenture pursuant to Section 8.10).

         Except as otherwise provided in the related Series Supplement, the
         balance, if any, of the amount so withdrawn shall be released from the
         lien of this Indenture and paid by the Trustee (i) with respect to
         each Series of Bonds for which a REMIC election or elections has or
         have not been made and will not be made, to the Issuer or, upon Issuer
         Order, to its assignee, or (ii) where such an election or elections
         has or have been made or will be made, to the  Residual Interest that
         is entitled to such  assets as stipulated in the related Series
         Supplement, in each case subject to satisfaction of the following
         conditions:

                       (i)        no Default or Event of Default shall have 
                 occurred and be continuing,

                      (ii)        an Independent Accountant shall have
                 delivered to the Trustee the certificate or opinion in respect
                 of such Payment Date required by Section 8.9(b);

                 Trustee an Officers' Certificate stating that all conditions
                 precedent to such release specified in this subsection (d)
                 have been satisfied, and

                      (iv)        the Issuer shall have delivered to the
                 Trustee an Opinion of Counsel to the effect that all documents
                 delivered to the Trustee in connection with such release
                 comply as to form with the requirements of this subsection (d)

         Section 8.6      General Provisions Regarding Pledged Accounts.

                 (a)      Each Pledged Account shall relate solely to the Bonds
         of the Series with respect to which it was established and to the
         Certificates and other property securing such Series. Funds and other
         property in each Pledged Account shall not be commingled with any
         other moneys or property of the Issuer or any Affiliate thereof.
         Notwithstanding the foregoing, the Trustee may hold any funds or other
         property received or held by it as part of a Pledged 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 Trustee and the Trustee
         maintains adequate records indicating the ownership of all such funds
         or property and the portions thereof held for credit to each Pledged
         Account.

                 (b)      The Issuer will not direct the Trustee to make any
         investment of any funds in a Pledged Account or to sell any investment
         held in a Pledged Account except under the following terms and
         conditions:

                       (i)        each such investment shall be made in the
                 name of the Trustee (in its capacity as such) or in the name
                 of a Qualified Nominee of the Trustee (or, if, as indicated by
                 an Opinion of Counsel delivered to the Trustee, applicable law
                 provides for perfection of pledges of an investment not
                 evidenced by a certificate or other instrument through
                 registration of such pledge on books maintained by or on
                 behalf of the issuer of such investment, such pledge may be so
                 registered),

                      (ii)        the Trustee shall have sole control over such
                 investment, the income thereon and the proceeds thereof,

                     (iii)        any certificate or other instrument
                 evidencing such investment shall be delivered directly to the
                 Trustee or its agent, and

                      (iv)        the proceeds of each sale of such an
                 investment shall be remitted by the purchaser thereof directly
                 to the Trustee for deposit in the Pledged Account in which
                 such investment was held.

                 (c)      Except as otherwise provided in the related Series
         Supplement, if a REMIC election or elections has or have been made or
         will be made in respect of the assets securing such Series, prior to
         any disposition of any investment in a Pledged Account that would
         result in a gain to a REMIC of such Series, the Trustee shall inform
         the Issuer of its intention





                                     -103-
<PAGE>   106
         to dispose of such investment and of the possibility that such
         disposition could result in the imposition of taxes on "prohibited
         transactions" as defined in Section 860F of the Code.  If any amounts
         are needed for disbursement from a Pledged Account and sufficient
         uninvested funds are not available therein to make such disbursement,
         in the absence of an Issuer Order for the liquidation of investments
         held therein in an amount sufficient to provide the required funds,
         the Trustee shall cause to be sold or otherwise converted to cash a
         sufficient amount of the investments in such Pledged Account.

                 (d)      The Trustee shall not in any way be held liable by
         reason of any insufficiency in any Pledged Account except for losses
         on investments which are liabilities of the Trustee (or of any agent
         of the Trustee).


                 (e)      All investments of funds in a Pledged Account and all
         sales of investments held in a Pledged Account shall, except as
         provided below, be made by the Trustee in accordance with an Issuer
         Order.  Subject to compliance with the requirements of Section 8.2(b),
         such Issuer Order may authorize the Trustee to make the specific
         investments set forth therein, to make investments from time to time
         consistent with the general instructions set forth therein, or to make
         specific investments pursuant to written, telegraphic or telephonic
         instructions of the employees or agents of the Issuer identified
         therein, in each case in such amounts as such Issuer Order shall
         specify.

                 In the event that:

                       (i)        the Issuer shall have failed to give
                 investment directions to the Trustee by 12:30 p.m. Eastern
                 Time on any Business Day authorizing the Trustee to invest the
                 funds then in a Pledged Account,

                      (ii)        a Default or Event of Default with respect to
                 such Series shall have occurred and be continuing but the
                 Bonds of such Series shall not have been declared due and
                 payable pursuant to Section 5.2, or

                     (iii)        an Event of Default with respect to such
                 Series shall have occurred and be continuing, the Bonds of
                 such Series shall have been declared due and payable pursuant
                 to Section 5.2, and amounts collected or receivable from the
                 related Trust Estate are being applied in accordance with
                 Section 5.8,


         the Trustee shall invest and reinvest the funds then in each related
         Pledged Account to the fullest extent practicable, in such manner as
         the Trustee shall from time to time determine, but only in one or more
         Eligible Investments bearing interest or sold at a discount.  All
         investments made pursuant to clause (i) above shall mature on the next
         Business Day following the date of such investment, all such
         investments made pursuant to clause (ii) above shall mature no later
         than the maturity date therefor permitted by Section 8.2(b), or





                                     -104-
<PAGE>   107
         by the terms of any related Series Supplement, whichever is
         applicable, and all investments made pursuant to clause (iii) above
         shall mature no later than the first date following the date of such
         investment on which the Trustee proposes to make a distribution to
         Holders of Bonds of the related Series pursuant to Section 5.8.

                 (f)      Subject to the restriction on the maturity of
         investments set forth in Sections 8.2(b), or in any related Series
         Supplement, and notwithstanding paragraph (e) above, the Issuer will
         give appropriate and timely investment directions to the Trustee such
         that at the close of business on not more than two Business Days in
         any one calendar year not more than an aggregate of $50,000 of funds
         in the Pledged Accounts  for a Series are not invested pursuant,
         directly or indirectly, to an Issuer Order in Eligible Investments
         bearing interest or sold at a discount which mature on or after the
         opening of business on the next Business Day.

                 (g)      Unless it shall have otherwise agreed in writing with
         the Issuer, the Trustee shall not be required to enter into repurchase
         obligations for the investment of funds in any Pledged Account with
         any Person whose repurchase obligations would be Eligible Investments
         only if the requirements of subclause (b) of clause (iii) of the
         definition of the term "Eligible Investments" were complied with in
         connection with such investment.

         Section 8.7      Reports by Trustee to Bondholders.

         On each Payment Date for a Series the Trustee shall deliver a written 
report

                 (a)      to each Holder of Bonds of a Class of such Series on
         which a payment of principal and interest is then being made, setting
         forth the amount of such payment which represents principal and the
         amount which represents interest, and the principal amount of an
         Individual Bond of each such Class after giving effect to the payment
         of principal made on such Payment Date;

                 (b)      to each Holder of Bonds of a Class of such Series on
         which a payment of interest only is then being made, setting forth the

         Section 8.9      Reports by Independent Accountants.

                 (a)      At the Closing Date for a Series the Issuer shall
         appoint the firm of Independent Accountants which prepares and
         delivers the certificate or opinion required to be delivered under
         Section 2.12(e) as its Independent Accountants for purposes of
         preparing and delivering the reports or certificates with respect to
         such Series required by this Section 8.9.  Upon any resignation by
         such firm the Issuer shall promptly notify the Trustee and appoint a
         successor thereto that shall also be a firm of Independent Accountants
         of recognized national reputation.  If the Issuer shall fail to
         appoint a successor to a firm of Independent Accountants which has
         resigned on or before the fifteenth day after such resignation, the
         Trustee shall promptly notify the Issuer of such failure in writing.
         If the Issuer shall not have appointed a successor within ten days
         thereafter the Trustee shall promptly appoint a successor firm of
         Independent Accountants of recognized national reputation.  The fees
         of such successor shall be payable by the Issuer, and any fees not so
         paid by the Issuer may be paid by the Trustee on behalf of the Issuer,
         from amounts otherwise payable to the Issuer from the related
         Collection Account pursuant to Section 8.2(d).

                 (b)      The Issuer, or the Trustee on behalf of the Issuer,
         shall direct the firm of Independent Accountants appointed pursuant to
         subsection (a) (or any successor firm so appointed) to review, and
         prepare and deliver to the Trustee a report or certificate with
         respect to each Payment Date Statement specified in the related Series
         Supplement delivered by the Trustee pursuant to Section 2.9(e).

                 Such report or certificate shall state that

                       (i)        such Independent Accountants have reviewed 
                 such Payment Date Statement,

                      (ii)        they have performed the calculations required
                 to be made in connection therewith,

                     (iii)        they have reviewed the accountings of the
                 related Distributions and of the related Collection Account
                 furnished by the Trustee with respect to the Distribution Date
                 relative to such Payment Date Statement, and

                      (iv)        based upon such review, such firm of
                 Independent Accountants has no material exceptions to the
                 Trustee's calculations set forth in any of such Statements, or
                 that all of such exceptions are set forth in such report or
                 certificate.

         Such report or certificate shall be delivered to the Trustee, and a
         copy of such report or certificate shall be delivered to the Issuer,
         prior to the close of business on the second





                                     -107-
<PAGE>   110
         Business Day following the related Calculation Date. If such firm of
         Independent Accountants sets forth any material exceptions to the
         Trustee's Payment Date Statement in its report or certificate, the
         Trustee's Payment Date Statement shall be deemed to have been amended
         to reflect such exceptions, and a copy of such report shall be
         delivered to each Rating Agency rating the related Bonds.

                 (c)      If the Trustee shall fail to deliver to the Issuer
         any Payment Date Statement by the due date therefor, the Issuer shall,
         at the opening of business on the next Business Day after such due
         date, direct the firm of Independent Accountants appointed pursuant to
         subsection (a) to prepare and deliver to the Trustee such Payment Date
         Statement at the expense of the Issuer, no later than 2:00 p.m. on the
         Business Day following the day on which such direction was given. Any
         fees of such Independent Accountants not paid by the Issuer may be
         paid by the Trustee, on behalf of the Issuer, from amounts otherwise
         payable to the Issuer from the related Collection Account pursuant to
         Section 8.2(d).

         Section 8.10     Expense Fund.

         2.12(g) or 8.2(d) hereof, together with any other Eligible Investments
         in which amounts in such Expense Fund are or will be invested or
         reinvested during the term of the Bonds of such Series, shall be held
         by the Trustee subject to disbursement and withdrawal as herein
         provided, but shall not be security for the Bonds of such Series.

                 (b)      Except as otherwise provided in the related Series
         Supplement all or a portion of the Expense Fund for a Series shall be
         invested and reinvested at the Issuer's direction in one or more
         Eligible Investments.

                 (c)      Except as otherwise provided in the related Series
         Supplement amounts on deposit in the Expense Fund for a Series shall
         be applied by the Trustee to the payment of expenses relating to the
         administration of the Bonds of such Series (other than interest
         expense on such Bonds) specified in the related Series Supplement to
         the extent that such expenses have not been paid by the Issuer or from
         other sources.

                 (d)      Except as otherwise provided in the related Series
         Supplement, upon full and final payment of all Outstanding Bonds of
         the related Series and payment of all unpaid expenses relating to the
         administration of the Bonds of such Series (other than interest
         expense on such Bonds) covered by such Expense Fund, the Trustee shall
         pay to or upon the order of the Issuer all amounts remaining on
         deposit in the Expense Fund for such Series.

Substitute Certificates.

                 (a)      Except as otherwise provided in the related Series
         Supplement, the Issuer shall have the right to Grant one or more
         Eligible Substitute Certificates for any one or more Certificates
         securing a Series of Bonds, any such substitution to take place on a
         Payment Date, subject, however, to satisfaction of the following
         conditions:

                       (i)        no Default or Event of Default shall have 
                 occurred and be continuing;

                      (ii)        if the Eligible Substitute Certificates to be
                 Granted in substitution for the Certificates to be released
                 are issued in definitive or certificated form, such Eligible
                 Substitute Certificates, registered in the name of the Trustee
                 (or, if requested by the Trustee, in the name of its Qualified
                 Nominee) shall have been delivered to the Trustee;

                     (iii)        if the Eligible Substitute Certificates to be

                 from a bank, broker, clearing corporation or other Person that
                 maintains securities accounts for the Issuer or the Trustee
                 and is acting in that capacity with respect to such Eligible
                 Substitute Certificates that either (1) ownership of such
                 Eligible Substitute Certificates in the name of the Issuer and
                 the Grant thereof to the Trustee have been entered on the
                 securities accounts books of such Person or (2) ownership of
                 such Eligible Substitute Certificates in the name of the
                 Trustee has been entered on the securities accounts books of
                 such Person;

                      (iv)        the Trustee shall have received a certificate
                 or opinion from a firm of Independent Accountants stating that

                 proposed to be released and of the Eligible Substitute
                 Certificates proposed to be Granted in substitution therefor,

                 Eligible Substitute Certificates to be granted in substitution
                 therefor and the Issuer's calculations of the aggregate
                 Certificate Principal Balance of all of the Certificates
                 pledged to secure the Bonds immediately following the
                 substitutions and (3) the Issuer's calculations demonstrating
                 that the Eligible Substitute Certificates proposed to be
                 Granted in substitution for the Certificates to be released
                 satisfy all conditions precedent to such release and
                 substitution set forth in the Indenture and the related Series
                 Supplement that are of a type that can be verified by
                 mathematical computations and (B) based on such review,
                 nothing has come to their attention that

                 the Issuer's calculations were not made in compliance with the
                 terms of the Indenture and the related Series Supplement and

                 Certificate stating that all conditions precedent to such

                 have been satisfied and (C) of the opinion required by Section
                 2.12(c) but only as applicable to the portion of the Trust

                 Substitute Certificates, as to the fair market value of such
                 Eligible Substitute Certificates, which determination of fair

                 quotations as of a date not earlier than three Business Days
                 prior to the date of Grant to the Trustee.

                 (b)      Upon any such Grant, the Trustee shall transfer and
         assign the replaced Certificates to the Issuer whereupon they shall be
         released from, and no longer subject to, the lien of the Indenture.

                            SUPPLEMENTAL INDENTURES


Section 9.1      Supplemental Indentures without Consent of Bondholders

         Without the consent of the Holders of any Bonds, the Issuer, when
authorized by a Board Resolution, and the Trustee, at any time and from time to
time, may enter into one or more indentures supplemental hereto, in form
satisfactory to the 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 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 Series of Bonds, as
         herein set forth, additional conditions, limitations and restrictions
         thereafter to be observed;

                 (3)      to set forth the terms of, and security for, any
         Series that has not theretofore been authorized by a Series
         Supplement;

                 (4)      to modify or eliminate any of the terms of this
         Indenture; provided, however, that

                          (A)     such supplemental indenture shall expressly
                 provide that any such modifications or eliminations shall not
                 be effective with respect to any Outstanding Bond of any
                 Series created prior to the execution of such supplemental
                 indenture; and

                          (B)     the Trustee may, in its discretion, decline
                 to enter into any such supplemental indenture which, in its
                 opinion, would adversely affect its own rights, duties or
                 immunities;

                 (5)      to evidence the succession of another Person to the
         Issuer, and the assumption by any such successor of the covenants of
         the Issuer herein and in the Bonds contained, or the appointment of an
         alternate Trustee under Section 6.16;




                                     -111-
<PAGE>   114
                 (6)      to add to the covenants of the Issuer, for the
         benefit of the Holders of all Bonds or of the Bonds of any Series, or
         to surrender any right or power herein conferred upon the Issuer;

                 (7)      to cure any ambiguity, to correct or supplement any
         provision herein which 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; provided that such
         action shall not adversely affect in any material respect the
         interests of the Holders of any Series of Bonds; and provided,
         further, that the amendment shall not be deemed to adversely affect in
         any material respect the interests of the Holders of any Series of
         Bonds if the Person requesting the amendment obtains a letter from
         each Rating Agency that the amendment would not result in the
         downgrading or withdrawal of the ratings then assigned to any Series
         of Bonds;

                 (8)      to provide for the issuance of Bonds of any Series
         (including Bonds of a Series theretofore authorized and then
         Outstanding) or any Class within such Series in bearer form with
         coupons ("Bearer Bonds") and for the exchangeability of Bearer Bonds
         and Bonds of the same Series and Class issued in registered form
         ("Registered Bonds"); any such supplemental indenture may provide for
         payments on Bearer Bonds only outside the United States and for
         appointment of a foreign Paying Agent that does not satisfy the
         requirements of clause (ii) of the definition of the term "Eligible
         Investments" but is otherwise acceptable to the rating agencies that
         rated the initial Series of the Bonds and may also contain any
         provisions as may in the Issuer's judgment be necessary, appropriate
         or convenient (a) to permit the Bonds to be issued and sold to or held
         in bearer form by non-United States Persons, (b) to establish
         entitlement to an exemption from United States withholding tax or
         reporting requirements with respect to payments on the Bonds, (c) to
         comply, or facilitate compliance, with other applicable laws or
         regulations, (d) to provide for usual and customary provisions for
         communication (by notice publication, maintenance of lists of holders
         of Bearer Bonds who have provided names and addresses for such
         purpose, or otherwise) with holders of Bearer Bonds, or (e) to
         otherwise effectuate provisions for the issuance of Bearer Bonds and
         their exchangeability with Registered Bonds (under no circumstances
         will this provision allow the Trustee or the Issuer to issue a second
         Class of "residual interests" as defined in the Code);

                 (9)      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 TIA or under any similar federal
         statute hereafter enacted, and to modify, eliminate or add to the
         provisions of this Indenture to such extent as shall be necessary or
         appropriate to conform to any provisions of the TIA, as the same may
         from time to time be amended; or

                 (10)     if a REMIC election or elections has or have been
         made or will be made in respect of the Trust Estate or such other

         Bonds of a Series, to modify, eliminate or add to the provisions of
         this Indenture to such extent as shall be necessary (i) to maintain
         the qualification of such assets as a REMIC under the Code or (ii) to
         avoid or minimize the risk of the imposition of any tax on the Issuer,
         the Trust Estate or another Person under the Code that would be a
         claim against the Issuer, Trust Estate or such other Person, as the
         case may be, or (iii) to prevent a REMIC Loss, provided that (a) there
         shall have been delivered an Opinion of Counsel to the effect that
         such action is necessary to maintain such qualification or to avoid
         any such tax or minimize the risk of its imposition or to prevent such
         prohibited transaction, respectively, and (b) such supplemental
         indenture shall not have any of the effects described in paragraphs
         (1) through (6) of the proviso to Section 9.2 of this Indenture.

         Section 9.2      Supplemental Indentures with Consent of 
Bondholders.

         With the consent of the Holders of Bonds representing not less than
two-thirds of the Aggregate Current Principal Amount of all Outstanding Bonds
in case Outstanding Bonds of all Series are to be affected or with the consent
of the Holders of Bonds representing not less than 66 2/3% of the Aggregate
Current Principal Amount of the Outstanding Bonds of each Series to be affected
in case one or more, but less than all, of the Series of Outstanding Bonds are
to be affected, by Act of said Holders delivered to the Issuer and the Trustee,
the Issuer, when authorized by a Board Resolution, and the 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 Series or of modifying in any
manner the rights of the Holders of the Bonds of such Series under this
Indenture; provided, however, that no such supplemental indenture shall,
without the consent of the Holder of each Outstanding Bond affected thereby:

                 (1)      change the Stated Maturity of the final installment
         of the principal of, or any installment of interest on, any Bond or
         reduce the principal amount thereof, the Bond Interest Rate thereon or
         the Redemption Price with respect thereto, change Bond Redemption Date
         for any Series of Bonds, 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 Stated Maturity thereof or for the enforcement of the payment of
         the entire remaining unpaid principal amount of any Bond on or after
         the Stated Maturity of the final installment of the principal thereof
         (or, in the case of redemption, on or after the applicable Redemption
         Date);

                 (2)      reduce the percentage of the Aggregate Current
         Principal Amount of the Outstanding Bonds of any Series, 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;





                                     -113-
<PAGE>   116
                 (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 ranking prior to or
         on a parity with the lien of this Indenture with respect to any part
         of a Trust Estate 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; or

                 (6)      modify any of the provisions of this Indenture in
         such manner as to affect the calculation of the Debt Service
         Requirement for any Payment Date for any Series of Bonds (including
         the calculation of any of the individual components of such Debt
         Service Requirement) or to affect rights of the Holders of Bonds of
         any Series to the benefits of any provisions for the mandatory
         redemption of Bonds of such Series contained herein or in the related
         Series Supplement.

         Notwithstanding any of the foregoing, prior to the date on which the
Class Imputed Principal Balance of each Class of Senior Bonds of a Series has
been reduced to zero, no amendment, variation or modification shall be made to
Article V hereof in respect of any Series of Bonds without the consent of the
Holders representing not less than 100% of the Aggregate Current Principal
Amount of all Outstanding Senior Bonds of such Series.  The consent of the
Holders of any Junior Bonds of such Series shall not be required to be obtained
prior to making any amendment for such series to Article V above for so long as
any Senior Bond of such Series is Outstanding.  Upon reduction to zero of the
Class Imputed Principal Balance of each Class of Senior Bonds of a Series, no
amendment, variation or modification to Article V hereof shall be made in
respect of such Series of Bonds without the consent of the Holders representing
not less than 66 2/3% of the Aggregate Current Principal Amount of the Highest
Priority Junior Class of such Series.

         The Trustee may in its discretion determine whether or not any Bonds
of any particular Series would be affected by any supplemental indenture and
any such determination shall be conclusive upon the Holders of all Bonds,
whether theretofore or thereafter authenticated and delivered hereunder.  The
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.





                                     -114-
<PAGE>   117
         Promptly after the execution by the Issuer and the Trustee of any
supplemental indenture pursuant to this Section, the Issuer shall mail to the
Holders of the Bonds of each Series to which such supplemental indenture
relates a notice setting forth in general terms the substance of such
supplemental indenture. Any failure of the Issuer 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 9.3      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 Trustee shall be entitled to
receive, and (subject to Section 6.1) 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.  In addition, in executing any
supplemental indenture which modifies an existing trust created by this
Indenture, the Trustee shall require, as a condition of such execution or
acceptance if a REMIC election or elections has or have been made or will be
made in respect of the Trust Estate or such other assets specified in such
election and securing such Series of Bonds, a Non-Disqualification Opinion.
The Trustee may, but shall not (except to the extent required in the case of a
supplemental indenture entered into under Section 9.1(8)) be obligated to,
enter into any such supplemental indenture which affects the Trustee's own
rights, duties or immunities under this Indenture or otherwise.


         Section 9.4      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 of any Series to which such supplemental indenture relates
which have theretofore been or thereafter are authenticated and delivered
hereunder shall be bound thereby.


         Section 9.5      Conformity with Trust Indenture Act.

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


         Section 9.6      Reference in Bonds to Supplemental
Indentures.

         Bonds authenticated and delivered after the execution of any
supplemental indenture pursuant to this Article which relates to the Series of
which such Bonds are a part may, and if required by the Issuer shall, bear a
notation in form approved by the 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 Trustee and the Issuer, to any such
supplemental indenture which relates to the Series





                                     -115-
<PAGE>   118
of which such Bonds are a part may be prepared and executed by the Issuer and
authenticated and delivered by the Trustee in exchange for Outstanding Bonds of
such Series.

         Section 9.7      Amendments to Governing Documents.

         Except as is otherwise provided in Section 3.8(c) the 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 Trustee of:

                 (1)      an Officer's 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 9.7
         have been satisfied; and

                 (2)      written confirmation from each of the rating agencies
         that rated any Series of the Issuer's Bonds that the implementation of
         the proposed amendment or waiver will not adversely affect their
         respective ratings of any Series of Bonds.

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

         Nothing in this Section 9.7 shall be construed to require that any
Person obtain the consent of the 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 Trustee is not prohibited by
the Indenture or by the terms of the document that is the subject of the
proposed amendment or waiver.

                              REDEMPTION OF BONDS


         Section 10.1     Redemption.

         All the Bonds of a Series may be redeemed in whole, but not in part,
on any Payment Date for such Series in accordance with and subject to the
provisions relating to such redemption contained in the related Series
Supplement.  If the Issuer shall elect to redeem the Bonds of a Series pursuant
to this Section 10.1 and the related Series Supplement, it shall furnish notice
of such election to the 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 10.2 to each Holder of such Bonds.


         Section 10.2     Form of Redemption Notice.

         Unless otherwise specified in the related Series Supplement notices of
redemptions of Bonds shall be given by the Trustee in the name and at the
expense of the Issuer and shall be mailed, or caused to be mailed, no later
than five days prior to such Payment Date on which such Bonds are to be
redeemed to the Persons who were Holders of such Bonds at the close of business
on the tenth Business Day prior to such Payment Date notwithstanding the Record
Date otherwise applicable.

         Unless otherwise provided in the related Series Supplement, no prior
notice of redemption at the request of a Bondholder or redemption of Book Entry
Bonds shall be required.

                 All notices of redemption shall state:

                 (1)      the Payment Date on which such redemption will take
         place,

                 (2)      the Redemption Price at which the Bonds of such
         Series 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
         maintained as provided in Section 3.2), 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 10.3     Bonds Payable on Payment Date.

         Notice of redemption having been given as provided in Section 10.2,
the Bonds or portions thereof so to be redeemed shall, on the applicable
Payment Date, become due and payable at the Redemption Price and (unless the
Issuer shall default in the payment of the Redemption Price) no interest shall
accrue on such Payment Date.


         Section 10.4     Right of Redemption by Holder.

                 (a)      Unless the Bonds of a Series have been declared due
         and payable prior to their Stated Maturity by reason of an Event of
         Default, a Holder may request the redemption of Bonds of one or more
         Classes of such Series if the related Series Supplement provides that
         such Class or Classes shall be subject to redemption as so provided in
         this Section 10.4.  A Bondholder may request redemption by delivering
         the following to the Trustee on or before the Tender Date:   (i) a
         written request for redemption in form satisfactory to the Trustee
         (such as the form appearing on the back of each Bond), by the
         Bondholder or the Bondholder's legal representative, with appropriate
         evidence of authority; (ii) in the case of Definitive Bonds, the
         certificate or certificates representing the Bond or Bonds for which
         redemption is being requested, and (iii) in the case of a request on
         behalf of a deceased Holder, appropriate evidence of death and any tax
         waivers requested by the Trustee.  With respect to each Class of Bonds
         subject to redemption at the request of Holders, on each Payment Date
         for such Series, the Issuer shall redeem Bonds with respect to which
         redemption has been properly requested in the order of priority
         described in paragraph (b) of this Section 10.4 and subject to the
         limitations that (1) except as set forth in such subsection (b), the
         Issuer shall not, on any one Payment Date, redeem from any personal
         representative, surviving joint tenant or surviving tenant by the
         entirety of a deceased Holder more than one hundred Individual Bonds
         of such Series or redeem from any other Holder more than ten
         Individual Bonds of such Series, unless all other Holders of Bonds for
         which redemption has been properly requested for such Payment Date
         have had their Bonds redeemed up to such limitations, and (2) with
         respect to each Class of a Series subject to redemption pursuant to
         this Section 10.4, the Issuer shall, on each Redemption Date, only
         make redemptions to the extent of the aggregate amount of principal
         payable on the Bonds of such Class on such Payment Date, rounded down
         to the nearest Individual Bond (the "Class Redemption Amount").  Bonds
         which have been accepted for Redemption shall become due and payable
         on the applicable Redemption Date and shall cease to bear interest as
         of the end of the Interest Accrual Period for such Redemption Date.
         Upon presentation and surrender of such Bonds for redemption on or
         after the Redemption Date therefor, such Bonds shall be redeemed by
         the Issuer at the Redemption Price, together with accrued interest.
         Installments of interest due on or prior to a Redemption Date shall
         continue to be payable to the Holders of such Bonds as of the
         applicable Record Date according to their terms and the provisions of
         Section 2.9.

<PAGE>   121
                 (b)      Subject to the limitations provided in subsection (a)
         of this Section 10.4, with respect to each Redemption Date and with
         respect to each Class, requests for redemption of Deceased Holder
         Bonds shall be accepted in the order of receipt of such requests by
         the Trustee to the extent permitted by the one hundred Individual Bond
         limitation referred to in Section 10.4(a); requests for redemption of
         Bonds other than Deceased Holder Bonds shall be accepted in the order
         of receipt of such requests by the Trustee to the extent permitted by
         the ten Individual Bond limitation referred to in Section 10.4(a),
         after all requests for redemption of Deceased Holder Bonds of the same
         Class theretofore submitted have been accepted within the one hundred
         Individual Bond limitation.  With respect to each Redemption Date, the
         Issuer shall accept requests for redemption of Deceased Holder Bonds
         in excess of the one hundred Individual Bond limitation, but only to
         the extent of the Class Redemption Amount for such Class for such
         Series after all requests for redemption in this subsection (b) with
         respect to such Redemption Date within the one hundred Individual Bond
         and ten Individual Bond limitations set forth above have been
         accepted.  With respect to each Redemption Date, the Issuer shall
         accept requests for redemption of Bonds other than Deceased Holder
         Bonds in excess of the ten Individual Bond limitation, but only to the
         extent of the Class Redemption Amount for such Class for such Series
         after all other requests for redemption in this subsection (b) with
         respect to such Redemption Date within the one hundred Individual Bond
         and ten Individual Bond limitations set forth above have been
         accepted.  With respect to each Redemption Date, the Issuer shall
         accept requests for redemption of Bonds other than Deceased Holder
         Bonds in excess of the ten Individual Bond limitation, but only to the
         extent of the Class Redemption Amount for such Class for such Series
         after all other requests for redemption in this subsection (b) with
         respect to such Redemption Date have been accepted.  Subject to the
         foregoing provisions, requests for redemption shall be accepted in the
         order that they were received by the Trustee.

                 (c)      In order to obtain redemption, the Holder or the
         personal representative, surviving joint tenant or surviving tenant by
         the entirety of a deceased Holder must deliver to the Trustee on or
         before the Tender Date preceding the Redemption Date:  (i) a written
         request for redemption in form satisfactory to the Trustee (such as
         the form appearing on the certificate representing the Bonds), signed
         by the Holder or the Holder's legal representative (with appropriate
         evidence of authority), (ii) the certificates representing the Bond or
         Bonds for which redemption is being requested, and (iii) in the case
         of Deceased Holder Bonds, appropriate evidence of death and any tax
         waivers required by the Trustee.  No particular forms of request for
         redemption or authority to request redemption are necessary (but the
         form set forth on the form of Bond in Section 2.2 shall be
         sufficient). Requests for redemption of Bonds received by the Trustee
         after the Tender Date preceding the Redemption Date, and requests for
         redemption not accepted in respect of such Redemption Date, whether on
         behalf of a deceased Holder or otherwise, will be treated as a request
         for redemption on the next succeeding Redemption Date, and the Bonds
         submitted will be held by the Trustee, until the request is accepted
         or withdrawn, except that the Trustee, in its discretion, may cancel
         the certificates representing any such Bonds provided that it shall





                                     -119-
<PAGE>   122
         maintain a record of the Bonds so cancelled and such Bonds shall
         continue to be deemed Outstanding for all purposes.  Within the first
         five Business Days of any month, the Trustee shall notify each Holder
         whose Bonds have been accepted for redemption in whole or in part on
         the Redemption Date in such month.  Only whole Individual Bonds may be
         redeemed.

                 (d)      For purposes of this Section, the death of a tenant
         by the entirety, joint tenant or tenant in common will be deemed the
         death of a Holder, and the entire principal amount of the Bond so held
         will be deemed to be a Deceased Holder Bond.  The death of a person
         who, during his lifetime, was entitled to substantially all of the
         beneficial interests of ownership of a Bond will be deemed the death
         of the Holder, regardless of the registered Holder, if such beneficial
         interest can be established to the satisfaction of the Trustee.  Such
         beneficial interest shall be deemed to exist in typical cases of
         street name of nominee ownership, ownership under the Uniform Gifts to
         Minors Act, community property or other joint ownership arrangement
         between a husband and wife, and trust and certain other arrangements
         where a person has substantially all of the beneficial ownership
         interests in the Bonds during his or her lifetime.  Beneficial
         interest shall include the power to sell, transfer or otherwise
         dispose of a Bond and the right to receive the proceeds therefrom, as
         well as interest and principal payable with respect thereto.

                 (e)      To the extent that the Class Redemption Amount as
         defined under Section 10.4(a) for a Principal Payment Date exceeds the
         aggregate amount of Bonds of a Class to be redeemed on such Principal
         Payment Date at the option of the Holders of such Class, Bonds of such
         Class shall be mandatorily redeemed by the Issuer at the price
         specified in the related Series Supplement.  Unless otherwise provided
         in the related Series Supplement, if less than all of the Bonds of any
         such Class are to be redeemed, the particular Bonds to be redeemed
         shall be selected by the Trustee from the Outstanding Bonds of such
         Series not previously called or accepted for redemption, not more than
         30 days prior to the applicable Principal Payment Date.  The Trustee
         shall select the Bonds to be redeemed by random lot.  Only whole
         Individual Bonds may be redeemed.

                 The Trustee shall promptly notify the Issuer in writing of the
         Individual Bonds selected for redemption pursuant to this Section
         10.4(e) and, in the case of any Bond selected for partial redemption,
         the principal amount thereof to be redeemed.

                 (f)      Beneficial Owners of Book Entry Bonds may tender
         their interest in Bonds for redemption on any Principal Payment Date
         subject to the limitations established in this Section 10.4.  If, and
         to the extent provided in the related Series Supplement, the Clearing
         Agency will receive requests for redemption and requests for
         withdrawal, determine the order of receipt of request for redemption,
         select Bonds to be mandatorily redeemed, provide notices of redemption
         and/or make payments of the redemption price and accrued interest, if
         any, in accordance with the terms and provisions of the related Series
         Supplement and the rules and procedures of the Clearing Agency.

                 (g)      Each of the terms and provisions of this Section 10.4
         may be modified, with respect to any Series, by the related Series
         Supplement.

         Section 10.5     Withdrawal of Requests.

         Any requests for redemption pursuant to Section 10.4 may be withdrawn
by the persons making the same upon the delivery of a written request for such
withdrawal received by the Trustee not later than the Tender Date for a given
Redemption Date on which such Bond would otherwise be redeemable pursuant to
Section 10.4. If not so withdrawn, the redemption request will be irrevocable
with respect to the selection of Bonds for redemption on the Redemption Date
within such month.  In the event a request for redemption has been withdrawn as
provided herein, the Trustee shall return the certificate representing the Bond
or Bonds in respect of which the redemption request has been withdrawn or, in
the case of Bonds the certificates of which were cancelled by the Trustee
pursuant to Section 10.4(c), the Issuer shall execute, and the Trustee shall
authenticate and deliver, new certificates representing the Bonds in respect of
which the redemption request has been withdrawn, such new Bonds to be of the
same date and tenor as the Bonds cancelled under Section 10.4(c) in the amount
which remains outstanding.


         Section 10.6     Redemption Register.

         The Trustee shall maintain at its Corporate Trust Office a register in
which it shall record, in the order of receipt, all requests for redemption
received by the Trustee under Section 10.4.  The Trustee may establish such
procedures as it may deem fair and equitable in order to determine the order of
receipt of requests for redemption received by the Trustee on a single day, and
any such determination shall be conclusive.  In establishing procedures for
determining the order of receipt of request for redemption, the Trustee may
designate from time to time any particular person, department or office as the
designated recipient of such requests and provide that, after Holders have been
notified in writing of such designation, no request for redemption will be
deemed received until received by the person, department or office so
designated.  Unless withdrawn as provided in Section 10.5, all such requests
shall remain in effect until the Bonds which are the subject of such request
have been redeemed.

                                 MISCELLANEOUS


         Section 11.1     Compliance Certificates and Opinions.

         Upon any application or request by the Issuer to the Trustee to take
any action under any provision of this Indenture, the Issuer shall furnish to
the 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 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.

         Every certificate or opinion 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 or opinion 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 or opinion 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

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

         Section 11.2     Form of Documents Delivered to 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 





                                     -122-
<PAGE>   125
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 an officer 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 such certificate or Opinion of Counsel may be based, insofar as
it relates to factual matters, upon a certificate or opinion of, or
representations by, an officer or officers of the Issuer, stating that the
information with respect to such factual matters is in the possession of the
Issuer, unless such officer or counsel knows, or in the exercise of reasonable
care should know, that the certificate or opinion or representations with
respect to such matters 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 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 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 Trustee's right to rely upon the truth and accuracy
of any statement or opinion contained in any such document as provided in
Section 6.1(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 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 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 6.1(d).

         Section 11.3     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 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 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 6.1) conclusive in favor of the 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 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
         Trustee or the Issuer in reliance thereon, whether or not notation of
         such action is made upon such Bonds.

                 (e)      The Voting Record Date specified in this Indenture,
         or in the related Series Supplement for any Series of Bonds, shall be
         applicable with respect to all Acts of Bondholders under this Section
         11.3.

         Section 11.4     Notices, etc. to Trustee and Issuer.

         Any request, demand, authorization, direction, notice, consent, waiver
or Act of Bondholders or other documents provided or permitted by this
Indenture to be made upon, given or furnished to, or filed with





                                     -124-
<PAGE>   127
                 (1)      the Trustee by any Bondholder or by the Issuer shall
         be sufficient for every purpose hereunder if made, given, furnished or
         filed in writing to or with and received by the Trustee at its
         Corporate Trust Office, or

                 (2)      the Issuer by the Trustee or by any Bondholder shall
         be sufficient for every purpose hereunder (except as provided in
         Section 5.1(A)(3) and (4)) if in writing and mailed, first-class
         postage-prepaid, to the Issuer addressed to it at 2711 N. Haskell,
         Suite 1000, Dallas, Texas 75204 or at any other address previously
         furnished in writing to the Trustee by the Issuer.

         Section 11.5     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 which 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 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 Trustee shall be deemed to be a
sufficient giving of such notice.


         Section 11.6     Rules by Trustee and Agents.

         The Trustee may make reasonable rules for any meeting of Bondholders.
Any Agent may make reasonable rules and set reasonable requirements for its
functions.

         Section 11.7     Conflict with Trust Indenture Act.

         If any provision hereof limits, qualifies or conflicts with the duties
 imposed by operation of TIA Section 318(c), the imposed duties under the TIA
 shall control.


         Section 11.8     Effect of Headings and Table of Contents.

         The Article and Section headings herein and the Table of Contents are

         Section 11.9     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    Severability.

         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, any
alternate trustee appointed under Section 6.16 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,
Special Payment Date, or any other date on which principal of or interest on
any Bond or Overdue 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, Special Payment Date, or other date for
the payment of principal of or interest on any Bond or Overdue Bond, as the
case may be, 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, EACH SERIES SUPPLEMENT 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
2.12(c) or 3.6.


         Section 11.16    Corporate Obligation.

         No recourse may be taken, directly or indirectly, against any
incorporator, subscriber to the capital stock, stockholder, officer or director
of the Issuer or the Trustee or of any predecessor or successor of the Issuer
or the Trustee with respect to the Issuer's obligations with respect to the
Bonds or the obligations of the Issuer or the Trustee under this Indenture or
any certificate or other writing delivered in connection herewith or therewith.


         Section 11.17    Inspection.

         The Issuer agrees that, on reasonable prior notice, it will permit any
representative of the Trustee, during the Issuer's normal business hours, to
examine all of the 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 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 





                                     -127-

expense incident to the exercise by the Trustee of any right under this Section
11.17 shall be borne by the Issuer.

         Section 11.18    Usury.

         The amount of interest payable or paid on any Bond under the terms of
this Indenture shall be limited to an amount which 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), which
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 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 Trustee, refund the amount of such excess or, at
the option of the 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 Trustee for the benefit of Holders of Bonds for the use,
forbearance or detention of money shall, to the extent permitted by applicable
law, be amortized, prorated, allocated and spread throughout the full term of
such Bonds.


         Section 11.19    REMIC Status.

         The provisions of this Indenture shall be construed so as to carry out
the intention of the parties that the Trust Estate and any other assets
specified in such REMIC election or elections and securing a Series of Bonds,
be treated as a REMIC, if a REMIC election or elections has or have been made
or will be made in respect of the Trust Estate or such other assets, at all
times so long as any Bond of such Series is Outstanding (or would be treated as
Outstanding for purposes of a Non-Disqualification Opinion).


         Section 11.20    Reserved.


         Section 11.21    Appointment of Tax Matters Partner.

         If a REMIC election or elections has or have been made or will be made
in respect of the Trust Fund or any other assets specified in such REMIC
election or elections which assets secure the Bonds of a Series, the tax
matters partner for each such REMIC and for all purposes of the Code shall be
the Person designated as such in the related Series Supplement.

     Series 1997-NAMC 3 Supplement dated as of September 1, 1997, between CMC
SECURITIES CORPORATION IV, a Delaware corporation (together with its successors
and assigns as provided in the Indenture referred to below, the "Issuer"), and
THE FIRST NATIONAL BANK OF CHICAGO, a national banking association (together
with its successors in trust thereunder as provided in the Indenture, the
"Trustee"), as trustee under an Indenture dated as of September 1, 1997 (such
Indenture, as thereafter amended and supplemented, is referred to herein as the
"Indenture").

                             PRELIMINARY STATEMENT

     Section 2.3 of the Indenture provides, among other things, that the
Issuer, when authorized by its Board of Directors, and the Trustee may enter
into an indenture supplemental to the Indenture for the purpose of authorizing
a Series of Bonds and to specify certain terms of such Series of Bonds. The
Board of Directors of the Issuer has duly authorized the creation of a Series
of Bonds in an aggregate principal amount of $281,194,912 to be known as its
Collateralized Mortgage Obligations, Series 1997-NAMC 3 (the "Securities"), and
the Issuer and the Trustee are executing and delivering this Series 1997-NAMC 3
Supplement in order to provide for the Securities. The Securities shall be
"Bonds" for all purposes of the Indenture. All terms used in this Series
1997-NAMC 3 Supplement that are defined in the Indenture, either directly or by
reference therein, have the meanings assigned to them therein as supplemented
by Section 12 hereof, if applicable, except to the extent the context clearly
requires otherwise. Any such defined term that is defined in the Indenture as
relating to a particular Series rather than to all Bonds generally shall, when
used in this Series 1997-NAMC 3 Supplement, relate to the Series 1997-NAMC 3
Securities, whether or not expressly so stated herein. Unless provided to the
contrary, references to Sections shall be references to Sections of this Series
Supplement. If any provision of the Indenture conflicts with any provision of
this Series Supplement, the provisions of this Series Supplement shall control.

                                GRANTING CLAUSES

     The Issuer hereby Grants to the Trustee, for the exclusive benefit of the
Holders of the Series 1997-NAMC 3 Securities, all of the Issuer's right, title
and interest in and to (a) the Certificates (which are the "Conventional

which the Issuer has caused to be delivered to the Trustee herewith, and all
Distributions with respect thereto payable at any time on or after the first

(c) all proceeds of the conversion, voluntary or involuntary, of any of the

(as defined in the Pooling and Servicing Agreement). Such Grants are made,
however, in trust, to secure the Series 1997-NAMC 3 Securities, equally and
ratably, without prejudice or distinction between any Series 1997-NAMC 3
Security and any other Series 1997-NAMC 3 Security by reason of difference in
time of issuance or otherwise, and to secure (i) the payment of all amounts due
on the Series 1997-NAMC 3 Securities as such amounts become due in accordance
with their terms, (ii) the payment of all other sums payable under the
Indenture or this Series 1997-NAMC 3 Supplement with respect to the Series
1997-NAMC 3 Securities, and (iii) compliance with the provisions of the

the Indenture.

1.   The Securities.

     (a)      The Securities shall be designated generally as the Issuer's
              Collateralized Mortgage Obligations, Series 1997-NAMC 3. The
              Securities will be substantially in the respective forms annexed
              hereto as Exhibits A-1 through A-8. The Securities will be
              issuable in registered form only. Each of the Class FXA-6, Class
              FXA-7, Class A-3, Class A-6, and the Principal Only Securities
              will be issuable in denominations evidencing initial Security
              Principal Balances of not less than $1,000 and integral multiples
              of $1,000 in excess thereof and each of the Class FXA-1, Class
              FXA-2, Class FXA-3, Class FXA-4, Class FXA-5, Class A-1, Class
              A-4, Class A-5, Class A-7, Class A-8, Class A-9 and the Class B
              Securities will be issuable in denominations evidencing initial
              Security Principal Balances of not less than $250,000 and
              integral multiples of $1,000 in excess thereof, except that one
              Security of each such Class may be issued in an amount (whether
              greater or less than the applicable minimum denomination) such
              that the denomination of such Security and the aggregate
              denomination of all other outstanding Securities of such Class
              together equal the aggregate initial Security Principal Balance
              of such Class. Each Class of the Strip Securities will be
              issuable in denominations evidencing an initial Notional Amount
              of not less than $1.00 and integral multiples of $1.00 in excess
              thereof,


<PAGE>   8



              except that one Security of each such Class will be issuable in
              an amount such that the denomination of such Security and the
              aggregate denomination of all other outstanding Securities of
              such Class together equal the related initial Notional Amount of
              such Class. Each of the Class R and Class RP Securities will each
              be issuable in denominations evidencing initial Security
              Principal Balances of not less than $10.00 and integral multiples
              of $1.00 in excess thereof, such that the denomination of such
              Security and the aggregate denomination of all other outstanding
              Securities of such Class together equal the aggregate initial
              Security Principal Balance of such Class.

     Upon original issue, the Securities shall, upon the written request of the
Issuer executed by an officer of the Issuer, be executed and delivered by the
Trustee, authenticated by the Trustee and delivered to or upon the order of the
Issuer. The Securities shall be executed by manual or facsimile signature on
behalf of the Trustee in its capacity as trustee hereunder by a Responsible
Officer. Securities bearing the manual or facsimile signatures of individuals
who were at any time the proper officers of the Trustee shall bind the Trustee,
notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Securities or did not
hold such offices at the date of such Securities. No Security shall be entitled
to any benefit under this Agreement, or be valid for any purpose, unless there
appears on such Security a certificate of authentication substantially in the
form provided for herein executed by the Trustee by manual signature, and such
certificate upon any Security shall be conclusive evidence, and the only
evidence, that such Security has been duly authenticated and delivered
hereunder. All Securities issued on the Closing Date shall be dated the Closing
Date and any Securities delivered thereafter shall be dated the date of their
authentication.

     (b)      None of the Principal Only Securities, Class B-4 Securities,
              Class B-5 Securities, Class B-6 Securities, Class R Securities
              and Class RP Securities shall be Book-Entry Securities. Each
              Class of the Strip Securities, the Class FXA Securities, the
              Class A Securities, and the Class B-1, Class B-2, and Class B-3
              Securities shall initially be issued as one or more Securities
              registered in the name of the Depository or its nominee and,
              except as provided below, registration of such Securities may not
              be transferred by the Trustee except to another Depository that
              agrees to hold such Securities for the respective Security Owners
              with Ownership Interests therein. The Security Owners shall hold
              their respective Ownership Interests in and to each of the Strip
              Securities, the Class FXA Securities, the Class A Securities, and
              the Class B-1, Class B-2, and Class B-3 Securities through the
              book-entry facilities of the Depository and, except as provided
              below, shall not be entitled to Definitive Securities in respect
              of such Ownership Interests. All transfers by Security Owners of
              their respective Ownership Interests in the Book-Entry Securities
              shall be made in accordance with the procedures established by
              the Depository Participant or brokerage firm representing such
              Security Owner. Each Depository Participant shall transfer the
              Ownership Interests only in the Book-Entry Securities of Security



<PAGE>   9


              Owners it represents or of brokerage firms for which it acts as
              agent in accordance with the Depository's normal procedures.

     The Trustee, the Master Servicer and the Issuer may for all purposes
(including the making of payments due on the respective Classes of Book-Entry
Securities) deal with the Depository as the authorized representative of the
Security Owners with respect to the respective Classes of BookEntry Securities
for the purposes of exercising the rights of Securityholders hereunder. The
rights of Security Owners with respect to the respective Classes of Book-Entry
Securities shall be limited to those established by law and agreements between
such Security Owners and the Depository Participants and brokerage firms
representing such Security Owners. Multiple requests and directions from, and
votes of, the Depository as Holder of any Class of Book-Entry Securities with
respect to any particular matter shall not be deemed inconsistent if they are
made with respect to different Security Owners. The Trustee shall utilize the
next available record date in connection with solicitations of consents from or
voting by Securityholders and shall give notice to the Depository of such
record date.

     If (i)(A) the Issuer advises the Trustee in writing that the Depository is
no longer willing or able to properly discharge its responsibilities as
Depository and (B) the Issuer is not able to locate a qualified successor or
(ii) the Issuer at its option advises the Trustee in writing that it elects to
terminate the book-entry system through the Depository, the Trustee shall
notify all Security Owners, through the Depository, of the occurrence of any
such event and of the availability of Definitive Securities to Security Owners
requesting the same. Upon surrender to the Trustee of the Book-Entry Securities
by the Depository, accompanied by registration instructions from the Depository
for registration of transfer, the Trustee shall, at the Master Servicer's
expense or, if so requested by the Issuer, at the Issuer's expense, issue the
Definitive Securities. Such Definitive Securities will be issued in
denominations as provided in paragraph (a) above. Neither the Issuer nor the
Trustee shall be liable for any actions taken by the Depository or its nominee,
including, without limitation, any delay in delivery of such instructions and
may conclusively rely on, and shall be protected in relying on, such
instructions. Upon the issuance of Definitive Securities all references herein
to obligations imposed upon or to be performed by the Depository in connection
with the issuance of the Definitive Securities pursuant to this Section 1 shall
be deemed to be imposed upon and performed by the Trustee, and the Trustee and
the Issuer recognize the Holders of the Definitive Securities as
Securityholders hereunder.

2.   Registration of Transfer and Exchange of Securities.

     (a)      The Trustee shall maintain a Bond Register in which, subject to
              such reasonable regulations as it may prescribe, the Trustee
              shall provide for the registration of Securities and of transfers
              and exchanges of Securities as herein provided.

     (b)      Except as provided in Section 2(c), no transfer, sale, pledge or
              other disposition of a Class B-4 Security, Class B-5 Security, or
              Class B-6 Security, shall be made unless such transfer, sale,
              pledge or other disposition is exempt from the registration

              requirements of the Securities Act of 1933, as amended (the
              "Act"), and any applicable state securities laws or is made in
              accordance with said Act and laws. In the event that a transfer
              of a Class B-4 Security, Class B-5 Security, or Class B-6
              Security is to be made under this Section 2(b), (i) except with
              respect to sales by the Initial Purchaser, the Issuer may direct
              the Trustee to require an Opinion of Counsel acceptable to and in
              form and substance satisfactory to the Trustee and the Issuer
              that such transfer shall be made pursuant to an exemption,
              describing the applicable exemption and the basis therefor, from
              said Act and laws or is being made pursuant to said Act and laws,
              which Opinion of Counsel shall not be an expense of the Trustee,
              the Issuer or the Master Servicer, provided that such Opinion of
              Counsel will not be required in connection with the initial
              transfer of any such Security by the Issuer or any affiliate
              thereof, to an affiliate of the Issuer or the Initial Purchaser
              and (ii) the Trustee shall require the transferee to execute a
              representation letter, substantially in the form of Exhibit C-1
              hereto, and the Trustee shall require the transferor to execute a
              representation letter, substantially in the form of Exhibit C-2
              hereto, each acceptable to and in form and substance satisfactory
              to the Issuer and the Trustee certifying to the Issuer and the
              Trustee the facts surrounding such transfer, which representation
              letters shall not be an expense of the Trustee, the Issuer or the
              Master Servicer; provided however that such representation
              letters will not be required in connection with any transfer of
              any such Security by the Issuer to an affiliate of the Issuer, or
              the Initial Purchaser and the Trustee shall be entitled to
              conclusively rely upon a representation (which, upon the request
              of the Trustee, shall be a written representation) from the
              Issuer of the status of such transferee as an affiliate of the
              Issuer. Any such Securityholder (other than the Initial
              Purchaser) desiring to effect such transfer shall, and does
              hereby agree to, indemnify the Trustee, the Issuer, the Loan
              Seller and the Master Servicer against any liability that may
              result if the transfer is not so exempt or is not made in
              accordance with such applicable federal and state laws.

     (c)      Transfers of Class B-4, Class B-5 and Class B-6 Securities may be
              made in accordance with this Section 2(c) if the prospective
              transferee of a Security provides the Trustee and the Issuer with
              an investment letter substantially in the form of Exhibit C-3
              attached hereto, which investment letter shall not be an expense
              of the Trustee or the Issuer, and which investment letter states
              that, among other things, such transferee is a "qualified
              institutional buyer" as defined under Rule 144A. Such transfers
              shall be deemed to have complied with the requirements of Section
              2(b) hereof; provided, however, that no Transfer of any of the
              Securities may be made pursuant to this Section 2(c) by the
              Issuer. Any such Securityholder desiring to effect such transfer
              shall, and does hereby agree to, indemnify the Trustee and the
              Issuer against any liability that may result if the transfer is
              not so exempt or is not made in accordance with such applicable
              federal and state laws.

              located at 14 Wall Street, 8th Floor, New York, New York 10005
              (the "New York Office"). There shall be no Authenticating Agent

              Securities which the Securityholder making the exchange is
              entitled to receive. Every Security presented or surrendered for
              transfer or exchange shall (if so required by the Trustee or the
              Bond Registrar) be duly endorsed by, or be accompanied by a
              written instrument of transfer in the form satisfactory to the
              Trustee or the Bond Registrar duly executed by, the Holder

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

     (g)      All Securities surrendered for transfer and exchange shall be
              canceled and retained by the Trustee in accordance with the
              Trustee's standard procedures.

     (h)      No transfer of an ERISA Restricted Bond or an ERISA Prohibited

         otherwise) to the account of such Securityholder at a bank or other
         entity having appropriate facilities therefor, if such Securityholder
         has so notified the Trustee at least five Business Days prior to the
         related Record Date and such Securityholder is the registered owner of
         Securities the aggregate initial Security Principal Balance of which
         is not less than $1,000,000 (or, with respect to any Class of Strip
         Securities, is the registered owner of an initial Notional Amount of
         not less than $1,000,000 of such Class), or otherwise by check mailed

         Bond Register, such Securityholder's share (based on the aggregate of
         the Percentage Interests represented by Securities of the applicable
         Class held by such Holder) of the related Security Payment Amount, in
         each case to the extent of the related Available Payment Amount and
         the other funds available to make such payments as provided herein.

     (e) The Trustee shall, upon written request from the Master Servicer,

         designated in the name of the Trustee for the benefit of the
         Securityholders, which shall mature not later than the Business Day
         next preceding the Payment Date next following the date of such
         investment (except that (i) any investment in obligations of the
         institution with which the Collection Account is maintained may mature
         on such Payment Date and (ii) any other investment may mature on such
         Payment Date if the Trustee shall agree to advance funds on such
         Payment Date to the Collection Account in the amount payable on such
         investment on such Payment Date, pending receipt thereof to the extent
         necessary to make payments on the Securities) and shall not be sold or
         disposed of prior to maturity. All income and gain realized from any
         such investment shall be for the benefit of the Master Servicer and
         shall be subject to its withdrawal or order from time to time. The
         Issuer shall cause the Master Servicer out of the Master Servicer's
         own funds to deposit the amount of any losses incurred in respect of
         any such investments in the Collection Account immediately as realized
         without right of reimbursement.

     (f) Whenever the Trustee expects that the final payment with respect to
         any Class of Securities will be made on the next Payment Date, the
         Trustee shall, no later than five days after the Determination Date,
         mail to each Holder on such date of such Class of Securities a notice
         to the effect that:

         (1)    the Trustee expects that the final payment with respect to such
                Class of Securities will be made on such Payment Date but only
                upon presentation and surrender of such Securities at the
                office of the Trustee therein specified, and

         (2)    no interest shall accrue on such Securities from and after the
                end of the related Interest Accrual Period.


<PAGE>   28

         Any funds not paid to any Holder or Holders of Securities of such
Class on such Payment Date because of the failure of such Holder or Holders to
tender their Securities shall, on such date, be set aside and held in trust
uninvested and credited to the account of the appropriate non-tendering Holder
or Holders. If any Securities as to which notice has been given pursuant to
this Section 5(f) shall not have been surrendered for cancellation within six
months after the time specified in such notice, the Trustee shall mail a second
notice to the remaining non-tendering Securityholders instructing such
Securityholders to surrender their Securities for cancellation in order to
receive the final payment with respect thereto. If within six months after the
second notice all such Securities shall not have been surrendered for
cancellation, the Trustee shall take reasonable steps as directed by the
Issuer, or appoint an agent to take reasonable steps, to contact the remaining
non-tendering Securityholders concerning surrender of their Securities. The
costs and expenses of maintaining the funds in trust and of contacting such
Securityholders shall be paid out of the assets remaining in the Trust Estate.
If within nine months after the second notice any such Securities shall not
have been surrendered for cancellation, the Class R and Class RP
Securityholders shall be entitled to all unclaimed funds and other assets which
remain subject hereto. No interest shall accrue or be payable to any
Securityholder on any amount held in trust as a result of such Securityholder's
failure to surrender its Security(s) for final payment thereof in accordance
with this Section 5(f).

     (g) On each Payment Date, the Trustee shall pay to each Securityholder of
         record on the related Record Date (other than as provided in Section
         5(f) respecting the final payment), in the manner set forth in Section
         5(b), such Securityholder's share (based on the aggregate of the
         Percentage Interests represented by the Securities of the applicable
         Class held by such Securityholder) of the amount transferred from the
         Excess Proceeds Account to the Collection Account on the related
         Collection Account Deposit Date in the following order of priority;
         first, to the Class FX and Class II Securities (other than the Class
         FXP and Class P Securities) on a pro rata basis, to the extent of and
         in proportion to the interest portion of the aggregate amount of all
         Realized Losses allocated to the Securities of such Classes on such
         Payment Date or any previous Payment Date in accordance with Section 7
         and not subsequently recovered through any payment in accordance with
         this Section 5(g), and then second, to the Class FX and Class II
         Securities (other than the Strip Securities) on a pro rata basis, to
         the extent of and in proportion to the principal portion of the
         aggregate amount of all Realized Losses allocated to the Securities of
         such Classes on such Payment Date or any previous Payment Date in
         accordance with Section 7 and not subsequently recovered through any
         payment in accordance with Section 5(b), or in accordance with this
         Section 5(g), third, to the Holders of the Class B-1 Securities,
         fourth, to the Holders of the Class B-2 Securities, fifth, to the
         Holders of the Class B-3 Securities, sixth, to the Holders of the
         Class B-4 Securities, seventh, to the Holders of the Class B-5
         Securities, eighth, to the Holders of the Class B-6 Securities, in
         each case to the extent of the aggregate amount of all Realized Losses
         allocated to the Security of such Class on such Payment Date or any
         previous Payment Date in accordance with Section 7 and not
         subsequently recovered through 

<PAGE>   29

         any payment in accordance with this Section 5(g), and then ninth, the
         remainder to the Holders of the Class RP Securities. There shall be
         corresponding deemed payments with respect to the Corresponding
         Classes of Subaccounts. The payment of any amount in accordance with
         this Section 5(g) shall not have the effect of reducing the Security
         Principal Balance of any Security (or the Subaccount Principal Balance
         of any Subaccount) to which such payment is allocated.

allocated among the various Classes of Securities as determined by the Trustee
in accordance with the following provisions. All Realized Losses in respect of

until the Security Principal Balance of the Class B-2 Securities has been
reduced to zero, then, to the Class B-1 Securities until the Security Principal
Balance of the Class B-1 Securities has been reduced to zero, and, thereafter,
(x) any such Realized Losses on the Group I Mortgage Loans will be allocated,
if any such loss is on a Group I Discount Mortgage Loan, to the Class FXP
Securities in an amount equal to the related Discount Fraction of the principal
portion of such Realized Loss, and the remainder of such Realized Losses and
the entire amount of such Realized Losses on any other Group I Mortgage Loans
to the Classes of Class FXA and Class FXS Securities on a pro-rata basis of the
then outstanding Security Principal Balances thereof in the case of the
principal portion of a Realized Loss or based on the Accrued Interest thereon
in the case of an interest portion of a Realized Loss, and (y) any such
Realized Losses on the Group II Mortgage Loans will be allocated, if any such
loss is on a Group II Discount Mortgage Loan, to the Class P Securities in an

Class A, Class A-2 and Class S Securities on a pro-rata basis of the then
outstanding Security Principal Balances thereof in the case of the principal
portion of a Realized Loss or based on the Accrued Interest thereon in the case
of an interest portion of a Realized Loss. Any Excess Special Hazard Losses,
Excess Bankruptcy Losses, Excess Fraud Losses and Extraordinary Losses on
Non-Discount Mortgage Loans will be allocated among all Classes of the
Securities (other than the Class FXP and the Class P Securities) pursuant to a

bearing the same designation. Any Realized Losses allocated to a Subaccount
that comprises Components shall be allocated between such Components pro rata

allocated to the Class IB Subaccount if the Realized Loss is attributable to a
Group I Mortgage Loan and to the Class IIB Subaccount if the Realized Loss is
attributable to a Group II Mortgage Loan. Realized Losses for each Due Period

related Security Interest Rate on the Security Principal Balance, Subaccount
Principal Balance, Component Principal Balance, Notional Amount or Subaccount
Notional Amount, as the case may be, immediately prior to such Payment Date for

Accrued Interest on any such Class of Securities, Subaccount or Component of a
Subaccount, as the case may be, will be reduced by the amount of (i) Prepayment
Interest Shortfalls, if any, which are not covered by payments by the Master
Servicer pursuant to Section 4.01 of the Pooling and Servicing Agreement with
respect to such Payment Date, (ii) the interest portion (adjusted to the Net
Mortgage Rate) of Realized Losses (including Excess Special Hazard Losses,
Excess Fraud Losses, Excess Bankruptcy Losses and Extraordinary Losses), not
allocated solely to the Subordinate Securities pursuant to Section 7 hereof,
(iii) the interest portion of Advances previously made with respect to a
Mortgage Loan or REO Property which remained unreimbursed following the Cash

Losses, and (iv) any interest shortfalls due to interest that is not
collectible from the Mortgagor pursuant to the Soldiers' and Sailors' Civil
Relief Act of 1940, as amended, or similar legislation or regulations as in
effect from time to time, pro rata in proportion to their respective amounts of
Accrued Interest which would have resulted absent such reductions. In addition
to that portion of the reductions described in the preceding sentence that are
allocated to the Subordinate Securities, Accrued Interest on the Subordinate
Securities will be reduced by the interest portion (adjusted to the Net
Mortgage

"Available Payment Amount" shall mean, with respect to any Payment Date, the

Bankruptcy Amount may be further reduced by the Issuer (including accelerating
the manner in which such coverage is reduced) provided that prior to any such

13.  Actions by Trustee as Holder of Certificates.

     (a) With the consent of the Holders of Series 1997-NAMC 3 Securities
         entitled to at least 66% of the Voting Rights, the Issuer, when
         authorized by a Board Resolution, and the Trustee may take any action
         that by the terms of the Pooling and Servicing Agreement requires the
         consent of the holders of not less than 662/3% of the Fractional
         Undivided Interest of the Trust Fund (as defined in the Pooling and
         Servicing Agreement evidenced by a Certificate, including but not
         limited to: (1) entering into any amendments to the Pooling and
         Servicing Agreement; (2) removing or consenting to the removal of, and
         appointing or consenting to the appointment of, a successor Master
         Servicer; and (3) removing or consenting to the removal of, and
         appointing or consenting to the appointment of, the Person acting as
         trustee under the Pooling and Servicing Agreement; provided, however,
         that no such action shall, without the consent of the Holder of each
         Security affected thereby:

         (1)    reduce the amount of, or delay the timing of, payments received
                on its Respective Trust Fund that are required to be paid on
                any Certificate or change the repurchase price with respect
                thereto, change any place of payment where, or the coin or
                currency in which, any Certificate or any interest thereon is
                payable, or impair the right to institute suit for the
                enforcement of the payment of any installment of interest or
                principal due on any Certificate or adversely affect the tax
                consequences to any holder of a Certificate;

         (2)    change the requirement of the consent of the holders of the
                Certificate for any such action pursuant to the Pooling and
                Servicing Agreement;

         (3)    modify any of the provisions of this Section, except to
                increase any percentage specified herein; or


<PAGE>   63

         (4)    permit the creation of any lien ranking prior to or on a parity
                with the trust created by the Pooling and Servicing Agreement
                with respect to any part of any Trust Fund or terminate the
                trust created by the Pooling and Servicing Agreement on any
                property at any time subject thereto or deprive the Holder of
                any Security of the security afforded by any Certificate;

provided, however, that notwithstanding the foregoing provisions of this
Section, Issuer and the Trustee may, without the consent of any Holder of any
Series 1997-NAMC 3 Securities, consent to the release from or termination of
the trust created by the Pooling and Servicing Agreement with respect to any
Mortgage Loan when such action by the Issuer and the Trustee is specifically
authorized by any other provision of the Indenture, this Series 1997-NAMC 3
Supplement or the Pooling and Servicing Agreement.

     The Trustee may in its discretion determine whether or not any Series
1997-NAMC 3 Securities would be affected by any proposed action and any such
determination shall be conclusive upon the Holders of all Series 1997-NAMC 3
Securities, whether theretofore or thereafter authenticated and delivered
hereunder. The Trustee shall not be liable for any such determination made in
good faith.

     It shall not be necessary for any Act of Securityholders under this
Section to approve the particular form of any written instrument proposed to
effect such action, but it shall be sufficient if such Act shall approve the
substance thereof.

     Promptly after the execution by the Issuer and the Trustee of any written
instrument proposed to effect such action pursuant to this Section, the Issuer
shall mail to the Holders of the Series 1997- NAMC 3 Securities to which such
action relates a notice setting forth in general terms the substance of such
action. Any failure of the Issuer to mail such notice, or any defect therein,
shall not, however, in any way impair or affect the validity of any such
action.

     (b) The Issuer hereby acknowledges and agrees that should the Person
         acting as trustee under the Pooling and Servicing Agreement demand
         indemnity satisfactory to it as a condition precedent to taking any
         action requested by the Trustee, as holder of the Certificates, the
         Trustee hereunder shall have no duty or obligation to advance its own
         funds in fulfillment of such indemnity, but rather may request such
         indemnity from the Issuer or from the Holders of the Series 1997-NAMC
         3 Securities. Should the Trustee, in its sole discretion and without
         obligation, elect to advance its own funds for such purpose, the
         Issuer acknowledges and agrees to reimburse the Trustee, under and
         pursuant to Section 6.7 of the Indenture, within 15 days of its
         receipt of an invoice therefor, and further agrees to pay interest on
         the principal amount of such advance not so paid by such date at the
         lesser of (i) the prime rate announced from time to time by the
         Trustee, in its commercial banking capacity plus two percent (2%) per
         annum, calculated on the basis of a 360-day year and (ii) the Highest
         Lawful Rate.

15.  REMIC Administration.

     (a) The Trustee shall perform all duties of the Issuer under Section 4.3
         of the Indenture. The Trustee shall make elections to treat the Lower
         REMIC and Upper REMIC as REMICs under the Code and, if necessary,
         under applicable state law. Such elections will be made on Forms 1066
         or other appropriate federal tax or information return or any
         appropriate state return for the taxable year ending on the last day
         of the calendar year in which the Securities are issued. For the
         purposes of the REMIC elections in respect of the Trust Estate, the
         Class FX Securities, the Class II Securities, and the Class B
         Securities shall be designated as the "regular interests" and the
         Class R Securities shall be designated as the sole class of "residual
         interest" in the Upper REMIC. The Subaccounts shall be designated as
         the "regular interests" and the Class RP Securities shall be
         designated as the sole class of "residual interest" in the Lower
         REMIC, provided that the Class A-1 Subaccount and Class A-2 Subaccount
         shall be only one "regular interest" (subject to the foregoing, the
         Subaccounts shall be the "Lower REMIC Interests"). The Trustee shall
         not permit the creation of any "interests" in the Trust Estate (within
         the meaning of Section 860G of the Code) other than the interests
         represented by the Lower REMIC Interests and the Securities.

     (b) The Closing Date is hereby designated as the "Startup Day" of each of
         the Lower REMIC and Upper REMIC within the meaning of Section
         860G(a)(9) of the Code.

     (c) The Trustee shall pay out of its own funds, without any right of
         reimbursement from the Trust Estate, any and all expenses relating to
         any tax audit of the Trust Estate (including, but not limited to, any
         professional fees or any administrative or judicial proceedings with
         respect thereto that involved the Internal Revenue Service or state
         tax authorities), other than the expense of obtaining any tax related
         Opinion of Counsel not obtained in connection with such an audit and
         other than taxes, in either case except as specified in the Pooling
         and Servicing Agreement. The holder of the largest Percentage Interest
         of the Class R Securities shall be the tax matters person of the Upper
         REMIC and the holder of the largest Percentage Interest of the Class
         RP Securities shall be the tax matters person of the Lower REMIC, in
         each case in the manner provided under Treasury Regulations Section
         1.860F-4(d) and Temporary Treasury Regulations Section
         301.6231(a)(7)-1T and the Trustee is hereby irrevocably designated and
         shall serve as attorney-in-fact and agent for any such Persons that
         are tax matters persons. The Trustee, as designated by the tax matters
         persons, shall (i) act on behalf of the Upper REMIC and Lower REMIC in
         relation to any tax matter or controversy involving either the Upper
         REMIC or the Lower REMIC and (ii) represent the Upper REMIC and Lower
         REMIC in any 

<PAGE>   65

         administrative or judicial proceeding relating to an examination or
         audit by any governmental taxing authority with respect thereto. To
         the extent authorized under the Code and the regulations promulgated
         thereunder, each Holder of a Class R and a Class RP Security hereby
         irrevocably appoints and authorizes the Trustee to be its
         attorney-in-fact for purposes of signing any Tax Returns required to
         be filed on behalf of the related REMIC.

     (d) The Trustee shall prepare or cause to be prepared, sign and file all
         of the Tax Returns in respect of each Series 1997-NAMC 3 REMIC, other
         than Tax Returns required to be filed by the Master Servicer pursuant
         to Section 4.05 of the Pooling and Servicing Agreement. The expenses
         of preparing and filing such returns shall be borne by the Trustee
         without any right of reimbursement therefor. The Trustee shall cause
         the first federal income tax return of each Series 1997-NAMC 3 REMIC
         to include the information required by Treasury Regulation Section
         1.860D-1(d)(2) and Treasury Regulation Section 1.860F-4(b)(2).

     (e) The Trustee shall perform on behalf of the Trust Estate all reporting
         and other tax compliance duties that are the responsibility of the
         Trust Estate under the Code, REMIC Provisions or other compliance
         guidance issued by the Internal Revenue Service or any state or local
         taxing authority. Among its other duties, as required by the Code, the
         REMIC Provisions or other such compliance guidance, the Trustee shall
         provide (i) to any Transferor of a Class R or a Class RP Security such
         information as is necessary for the application of any tax relating to
         the transfer of a Class R or a Class RP Security to any Person who is
         not a Permitted Transferee, (ii) to Securityholders such information
         or reports as are required by the Code or the REMIC Provisions
         including reports relating to interest, original issue discount and
         market discount or premium (using the Prepayment Assumption) and (iii)
         to the Internal Revenue Service the name, title, address and telephone
         number of the person who will serve as the representative of the Trust
         Estate. In addition, the Master Servicer shall provide or cause to be
         provided to the Trustee, within ten (10) days after the Closing Date,
         all information or data that the Trustee reasonably determines to be
         relevant for tax purposes as to the valuations and issue prices of the
         Securities, including, without limitation, the price, yield,
         prepayment assumption and projected cash flow of the Securities.

     (f) The Trustee shall take such action and shall cause the Trust Estate
         created hereunder to take such action as shall be necessary to create
         or maintain the status of each Series 1997-NAMC 3 REMIC as REMICs
         under the REMIC Provisions. The Trustee shall not take any action,
         cause either the Upper REMIC or the Lower REMIC to take any action or
         fail to take (or fail to cause to be taken) any action that, under the
         REMIC Provisions, if taken or not taken, as the case may be, could (i)
         endanger the status of the either the Upper REMIC or the Lower REMIC
         as a REMIC or (ii) result in the imposition of a tax upon the Trust
         Estate (including but 


<PAGE>   66

         not limited to the tax on prohibited transactions as defined in
         Section 860F(a)(2) of the Code and the tax on contributions to a REMIC
         set forth in Section 860G(d) of the Code) (either such event, an
         "Adverse REMIC Event") unless the Trustee has received an Opinion of
         Counsel (at the expense of the party seeking to take such action but
         in no event shall such Opinion of Counsel be an expense of the
         Trustee) to the effect that the contemplated action will not, with
         respect to either the Upper REMIC or the Lower REMIC created
         hereunder, endanger such status or result in the imposition of such a
         tax. The Issuer shall cause the Master Servicer not to take or fail to
         take any action (whether or not authorized hereunder) as to which the
         Trustee has advised it in writing that it has received an Opinion of
         Counsel (which such Opinion of Counsel shall not be an expense of the
         Trustee) to the effect that an Adverse REMIC Event could occur with
         respect to such action. At all times as may be required by the Code,
         the Trustee will take no action, nor permit any such action, that it
         knows will cause substantially all of the assets of the Trust Estate
         to not consist of "qualified mortgages" as defined in Section
         860G(a)(3) of the Code and "permitted investments" as defined in
         Section 860G(a)(5) of the Code.

     (g) In the event that any tax is imposed on "prohibited transactions" of
         either the Upper REMIC or the Lower REMIC created hereunder as defined
         in Section 860F(a)(2) of the Code, on "net income from foreclosure
         property" of either the Upper REMIC or the Lower REMIC as defined in
         Section 860G(c) of the Code, on any contributions to either the Upper
         REMIC or the Lower REMIC after the Startup Day therefor pursuant to
         Section 860G(d) of the Code, or any other tax is imposed by the Code
         or any applicable provisions of state or local tax laws, such tax
         shall be charged (i) to the Trustee pursuant to Section 17 hereof, if
         such tax arises out of or results from a breach by the Trustee of any
         of its obligations hereunder, (ii) to the Master Servicer pursuant to
         Section 10.03 of the Pooling and Servicing Agreement, if such tax
         arises out of or results from a breach by the Master Servicer of any
         of its obligations under the Pooling and Servicing Agreement, or
         otherwise (iii) against amounts on deposit in the Security Account and
         shall be paid by withdrawal therefrom.

     (h) On or before April 15 of each calendar year, commencing April 15,
         1998, the Trustee shall deliver to the Master Servicer and each Rating
         Agency a certificate from a Responsible Officer of the Trustee stating
         the Trustee's compliance with this Section 15.

     (i) The Trustee shall, for federal income tax purposes, maintain books and
         records with respect to the Trust Estate on a calendar year and on an
         accrual basis.

     (j) The Trustee shall not permit the acquisition of any assets by either
         the Upper REMIC or the Lower REMIC unless it shall have received an
         Opinion of Counsel (which such Opinion of Counsel shall not be an
         expense of the Trustee) to the effect that the inclusion of such
         assets in either the Upper REMIC or the Lower REMIC will not 


<PAGE>   67

         cause either the Upper REMIC or the Lower REMIC to fail to qualify as
         a REMIC at any time that any Securities are outstanding or subject
         either the Upper REMIC or the Lower REMIC to any tax under the REMIC
         Provisions or other applicable provisions of federal, state and local
         law or ordinances.

     (k) The Trustee shall not enter into any arrangement by which either the
         Upper REMIC or the Lower REMIC will receive a fee or other
         compensation for services nor permit either of such REMICs to receive
         any income from assets other than "qualified mortgages" as defined in
         Section 860G(a)(3) of the Code or "permitted investments" as defined
         in Section 860G(a)(5) of the Code.

     (l) Solely for purposes of satisfying Section 1.860G-1(a)(4)(iii) of the
         Treasury Regulations, the "latest possible maturity date" by which the
         Subaccount Principal Balances of each Class of Lower REMIC Interests
         and the Security Principal Balances of each Class of Securities (other
         than the Class R and Class RP Securities) would be reduced to zero is
         the Payment Date immediately following the Distribution Date in
         October 2027, which is the Distribution Date immediately following the
         latest scheduled maturity of any Mortgage Loan.

16.  Prohibited Transactions and Activities.

     The Trustee shall not sell, dispose of or substitute for or permit the
selling, disposal of or substitution for any of the Mortgage Loans, except in
connection with (i) the foreclosure of a Mortgage Loan, including but not
limited to, the acquisition or sale of a Mortgaged Property acquired by deed in
lieu of foreclosure, (ii) the bankruptcy of the Trust Estate, (iii) the
optional termination of the Trust Estate pursuant to Section 14 of this
Agreement or (iv) a repurchase of Mortgage Loans by the Loan Seller pursuant to
the provisions of the Pooling and Servicing Agreement, nor will the Trustee
acquire or permit to be acquired any assets for the Trust Estate, nor sell or
dispose of or permit to be sold or disposed of any investments in the Custodial
Account, the Excess Proceeds Account, the Certificate Account or the Collection
Account for gain, nor accept any contributions to the Trust Estate after the
Closing Date, nor permit any modifications of a material term of a Mortgage
Loan that is not in default or with respect to which default is reasonably
foreseeable, unless it has received an Opinion of Counsel (at the expense of
the party seeking to cause such sale, disposition, substitution, acquisition,
or modification but in no event shall such Opinion of Counsel be an expense of
the Trustee) that such sale, disposition, substitution, acquisition,
contribution or modification will not (a) affect adversely the status of either
the Upper REMIC or the Lower REMIC as a REMIC or (b) cause either the Upper
REMIC or the Lower REMIC to be subject to a tax on "prohibited transactions" or
"contributions" pursuant to the REMIC Provisions.


<PAGE>   68

17.  Trustee Indemnification

     The Trustee agrees to indemnify the Trust Estate, the Issuer, the Loan
Seller and the Master Servicer for any taxes and costs including, without
limitation, any reasonable attorneys' fees imposed on or incurred by the Trust
Estate, the Issuer or the Master Servicer, as a result of a breach of the
Trustee's covenants set forth in Section 16 hereof.

18.  Information Regarding Mortgage Loans.

     The Issuer will cause the Master Servicer, pursuant to the Pooling and
Servicing Agreement, to provide the Trustee with certain information regarding
the Mortgage Loans underlying the Certificates. The Trustee shall not be
required to recompute, verify or recalculate the information supplied to it by
the Master Servicer and may conclusively rely and shall be protected in relying
on the accuracy of all such information in performing its duties and
responsibilities hereunder.

19.  Supplements, Modifications and Ratifications of Indenture.

     (a) The Trustee will be required to mail, in each year when required by

         Indenture, any amounts advanced by it under the Indenture, the amount,

     (c) References to "Residual Interest Holders" in the Indenture are hereby
         deemed to refer to the Holders of the Class R Securities with respect

                         of The First National Bank of Chicago, as trustee,

                         endorsement must be by "[Loan Seller] formerly known
                         as [previous name]";

                         have been recorded showing a complete chain of title
                         from the originator to the Loan Seller, with evidence
                         of recording thereon, or a copy thereof certified by

                         applicable, or if the original of such document has
                         not been returned from the applicable public recording
                         office, a true certified copy, certified by the Loan
                         Seller, of such original document together with

                         such document has been delivered for recording in the
                         appropriate recording office of the jurisdiction in

                         instrument, together with a certificate of receipt
                         from the recording office, certifying that such copy
                         represents a true and complete copy of the original
                         and that such original has been or is currently
                         submitted to be recorded in the appropriate
                         governmental recording office of the jurisdiction
                         where the Mortgaged Property is located), or if the
                         original power of attorney or other such instrument
                         has not been returned from the applicable public
                         recording office, a true certified copy, certified
                         by the Loan Seller, of the original power of
                         attorney or other instrument together with a
                         certification certifying that the original power of
                         attorney or other instrument has been delivered for
                         recording in the appropriate public recording office
                         of the jurisdiction in which the Mortgaged Property
                         is located; and

                  (viii) evidence of the original or certified to be true
                         copy, certified by the Loan Seller, of the Primary
                         Mortgage Insurance Policy, if required.

         If the Seller cannot deliver the original recorded Mortgage Loan
Documents or the original policy of title insurance, including riders and
endorsements thereto, on the Closing Date, the Loan Seller will, promptly upon
receipt of notice thereof and in any case not later than 180 days from the
Closing Date, deliver such original documents, including original recorded
documents, to the Trustee (unless the Loan Seller is delayed in making such
delivery by reason of the fact that such documents shall not have been returned
by the appropriate recording office). If delivery is not completed within 180
days solely due to delays in making such delivery by reason of the fact that
such documents shall not have been returned by the appropriate recording
office, the Loan Seller is required to deliver such documents to the Trustee
within such time period as specified in an officer's certificate of the Loan
Seller. In the event that documents have not been received by the date
specified in such officer's certificate of the Loan Seller, a subsequent
officer's certificate is required to be delivered by the Loan Seller by such
date specified in the prior officer's certificate of the Loan Seller, stating a
revised date for receipt of documentation. The procedure shall be repeated
until the documents have been received and delivered. The Loan Seller shall
continue to use its best efforts to effect delivery within 270 days of the
Closing Date. Upon receipt of any such document from the Loan Seller, the
Seller shall promptly deliver such document to the Trustee.

         The Loan Seller shall pay all initial recording fee for the
Assignments and any other fees in connection with the transfer of all original
documents to the Trustee. The Loan Seller shall prepare, in recordable form,
all Assignments necessary to assign the Mortgage Loans to the Trustee on behalf
of the Trust, and as promptly as practicable after the Closing Date, the Loan
Seller shall cause to be delivered to the appropriate public office for
recordation in the real property records the Assignment

  
                                      -22-

referred to in clause (iii) and to the extent necessary in clause (iv) of this
Section 2.01. While such Assignment to be recorded is being recorded, the
Trustee shall retain a photocopy of such Assignment. If any Assignment is lost
or returned unrecorded to the Trustee because of any defect therein, the Loan
Seller shall prepare a substitute Assignment or cure such defect, as the case
may be, and the Trustee shall cause such Assignment to be recorded in
accordance with this paragraph. If any Assignment is lost or returned
unrecorded because of any Trustee error, the Trustee shall cause such
Assignment to be recorded in accordance with this paragraph at its expense.

         All original documents relating to the Mortgage Loans which are not
delivered to the Trustee are and shall be held by the Master Servicer in trust
for the benefit of the Trustee on behalf of the Certificateholders.

         Except as may otherwise expressly be provided herein, neither the
Seller, the Loan Seller, the Master Servicer nor the Trustee shall (and the
Master Servicer shall ensure that no Sub-Servicer shall) assign, sell, dispose
of or transfer any interest in any Trust Fund or any portion thereof, or permit
any Trust Fund or any portion thereof to be subject to any lien, claim,
mortgage, security interest, pledge or other encumbrance of, any other Person.

         It is intended that the conveyance of the Mortgage Loans in each Loan
Group by the Seller to the Trustee as provided in this Section be, and be
construed as, a sale of the Mortgage Loans by the Seller to the Trustee for the
benefit of the Certificateholders of the related Series. It is, further, not
intended that such conveyance be deemed a pledge of the Mortgage Loans by the
Seller to the Trustee to secure a debt or other obligation of the Seller.
However, in the event that any Mortgage Loans are held to be property of the
Seller, or if for any reason this Agreement is held or deemed to create a
security interest in any Mortgage Loans, then it is intended that, (a) this
Agreement shall also be deemed to be a security agreement within the meaning of
Articles 8 and 9 of the New York Uniform Commercial Code and the Uniform
Commercial Code of any other applicable jurisdiction; (b) the conveyance
provided for in this Section shall be deemed to be a grant by the Seller to the
Trustee, for the benefit of the Certificateholders of the related Series, of a
security interest in all of the Seller's right (including the power to convey
title thereto), title and interest, whether now owned or hereafter acquired, in
and to (A) such Mortgage Loans, including the related Mortgage Notes, the
related Mortgages, any related insurance policies and all other documents in
the related Mortgage Files, (B) all amounts payable to the holders of such
Mortgage Loans in accordance with the terms thereof and (C) all proceeds of the
conversion, voluntary or involuntary, of the foregoing into cash, instruments,
securities or other property, including without limitation all amounts from
time to time held or invested in the related Certificate Account or the
Custodial Account, whether in the form of cash, instruments, securities or
other property; (c) the possession by the Trustee or its agent of the related
Mortgage Notes and such other items of property as constitute instruments,
money, negotiable documents or chattel paper shall be deemed to be "possession
by the secured party" or possession by a purchaser or a person designated by
such secured party, for purposes of perfecting the security interest pursuant
to the New York Uniform Commercial Code and the Uniform Commercial Code of any
other applicable jurisdiction (including, without limitation, Sections 9-305,
8-313 or 8-321 thereof); and (d) notifications to persons holding such
property, and acknowledgments, receipts or confirmations from persons holding
such property, shall be deemed notifications to, or acknowledgments, receipts
or confirmations from, financial intermediaries, bailees or agents (as
applicable) of the Trustee for the purpose of perfecting such security interest

  
                                      -23-

under applicable law. The Seller and the Trustee shall, to the extent
consistent with this Agreement, take such actions as may be necessary to ensure
that, if this Agreement were deemed to create a security interest in any
Mortgage Loans, such security interest would be deemed to be a perfected
security interest of first priority, in favor of the Trustee for the
Certificateholders of the related Series, under applicable law and will be
maintained as such throughout the term of the Agreement.

         2.02 Acceptance of any Trust Fund by the Trustee.

         The Trustee acknowledges receipt (subject to any exceptions noted in
the Initial Certification described below) of the documents referred to in
Section 2.01 above and all other assets included in each Trust Fund and
declares that it holds and will hold such documents and the other documents
delivered to it constituting the Mortgage Files, and that it holds or will hold
such other assets included in each Trust Fund (to the extent delivered or
assigned to the Trustee), in trust for the exclusive use and benefit of all
present and future Certificateholders of the related Series.

         The Trustee agrees, for the benefit of the Certificateholders, to
review each Mortgage File relating to a Mortgage Loan in the related Loan Group
on or before the Closing Date to ascertain that all documents required to be
delivered to it are in its possession, and the Trustee agrees to execute and
deliver to the Seller, the Loan Seller and the Master Servicer on the Closing
Date an Initial Certification in the form annexed hereto as Exhibit B to the
effect that, as to each Mortgage Loan listed in the applicable related Mortgage
Loan Schedule (other than any Mortgage Loan paid in full or any Mortgage Loan
specifically identified in such certification as not covered by such
certification), (i) all documents required to be delivered to it pursuant to
this Agreement with respect to such Mortgage Loan are in its possession, (ii)
such documents have been reviewed by it and appear regular on their face and
relate to such Mortgage Loan and (iii) based on its examination and only as to
the foregoing documents, the information set forth in items (i) - (vi), (xiv)
and (xv) of the definition of the "Mortgage Loan Schedule" accurately reflects
information set forth in the Mortgage File. Neither the Trustee nor the Master
Servicer shall be under any duty to determine whether any Mortgage File should
include any of the documents specified in clause (vi) of Section 2.01. Neither
the Trustee nor the Master Servicer shall be under any duty or obligation to
inspect, review or examine said documents, instruments, securities or other
papers to determine that the same are genuine, enforceable or appropriate for
the represented purpose or that they have actually been recorded or that they
are other than what they purport to be on their face.

         Within 90 days of the Closing Date the Trustee shall deliver to the
Seller, the Loan Seller and the Master Servicer Final Certifications in the
form annexed hereto as Exhibit C evidencing the completeness of the Mortgage
Files, with any applicable exceptions noted thereon.

         If in the process of reviewing the Mortgage Files and preparing the
certifications referred to above the Trustee finds any document or documents
constituting a part of a Mortgage File to be missing or defective in any
material respect (but only after giving effect to any time period set forth in
Section 2.01), the Trustee shall promptly notify the Loan Seller, the Master
Servicer and the Seller. The Trustee shall promptly notify the Seller of such
defect and request that the Loan Seller cure any such defect within 60 days
from the date on which the Loan Seller was notified of such defect, and if the
Loan Seller does not cure such defect in all material respects during such
period, the Trustee shall request that the Loan Seller purchase such Mortgage
Loan from the Trust Fund on

  
                                      -24-

<PAGE>   30




behalf of the Certificateholders of the applicable Series at the Purchase Price
within 90 days after the date on which the Loan Seller was notified of such
defect. It is understood and agreed that the obligation of the Loan Seller to
cure a material defect in, or purchase any Mortgage Loan as to which a material
defect in a constituent document exists shall constitute the sole remedy
respecting such defect available to Certificateholders of the applicable Series
or the Trustee on behalf of such Certificateholders. The Purchase Price for the
purchased Mortgage Loan shall be deposited or caused to be deposited upon
receipt by the Master Servicer in the Custodial Account with respect to the
applicable Series and, upon receipt by the Trustee of written notification of
such deposit signed by a Servicing Officer, the Trustee shall release or cause
to be released to the Loan Seller (or its designee) the related Mortgage File
and shall execute and deliver such instruments of transfer or assignment, in
each case without recourse, as the Loan Seller (or its designee) shall require
as necessary to vest in the Loan Seller (or its designee) ownership of any
Mortgage Loan released pursuant hereto and at such time the Trustee shall have
no further responsibility with respect to the related Mortgage File.

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

         (a) The Master Servicer hereby represents and warrants to and
             covenants with the Seller, the Loan Seller and the Trustee for the
             benefit of Certificateholders that:

                    (i)  The Master Servicer is, and throughout the term hereof
                         shall remain, a corporation duly organized, validly
                         existing and in good standing under the laws of the
                         State of Delaware (except as otherwise permitted
                         pursuant to Section 6.02), the Master Servicer is, and
                         shall remain, in compliance with the laws of each
                         state in which any Mortgaged Property is located to
                         the extent necessary to perform its obligations under
                         this Agreement, and the Master Servicer is, and shall
                         remain, approved to sell mortgage loans to and service
                         mortgage loans for FNMA and FHLMC;

                    (ii) The execution and delivery of this Agreement by the
                         Master Servicer, and the performance and compliance
                         with the terms of this Agreement by the Master
                         Servicer, will not violate the Master Servicer's
                         charter or bylaws or constitute a default (or an event
                         which, with notice or lapse of time, or both, would
                         constitute a default) under, or result in the breach
                         of, any material agreement or other instrument to
                         which it is a party or which is applicable to it or
                         any of its assets;

<PAGE>   31



                   (iii) The Master Servicer has the full power and authority
                         to enter into and consummate all transactions
                         contemplated by this Agreement, has duly authorized
                         the execution, delivery and performance of this
                         Agreement, and has duly executed and delivered this
                         Agreement;

                    (iv) This Agreement, assuming due authorization, execution
                         and delivery by the Seller and the Trustee,
                         constitutes a valid, legal and binding obligation of
                         the Master Servicer, enforceable against the Master
                         Servicer in accordance with the terms hereof, subject
                         to (A) applicable bankruptcy, insolvency,
                         reorganization, moratorium and other laws affecting
                         the enforcement of creditors' rights generally, and
                         (B) general principles of equity, regardless of
                         whether such enforcement is considered in a proceeding
                         in equity or at law;

                     (v) The Master Servicer is not in violation of, and its
                         execution and delivery of this Agreement and its
                         performance and compliance with the terms of this
                         Agreement will not constitute a violation of, any law,
                         any order or decree of any court or arbiter, or any
                         order, regulation or demand of any federal, state or
                         local governmental or regulatory authority, which
                         violation is likely to affect materially and adversely
                         either the ability of the Master Servicer to perform
                         its obligations under this Agreement or the financial

                                    unpaid and which has been assessed but is
                                    not yet due and payable;

                           (vi)     The terms of the Mortgage Note and the
                                    Mortgage have not been impaired, waived,
                                    altered or modified in any respect, except
                                    by written instruments which have been
                                    recorded to the extent any such recordation
                                    is required by law, or, necessary to
                                    protect the interest of the Trust and the
                                    related Certificateholders. No instrument
                                    of waiver, alteration or modification has
                                    been executed, and no Mortgagor has been
                                    released, in whole or in part, from the
                                    terms thereof except in connection with an
                                    assumption agreement and which assumption
                                    agreement is part of the Mortgage File and
                                    the terms of which are reflected in the
                                    applicable Mortgage Loan Schedule; the
                                    substance of any such waiver, alteration or
                                    modification has been approved by the

                           (vii)    The Mortgage Note and the Mortgage are not
                                    subject to any right of rescission,
                                    set-off, counterclaim or defense,
                                    including, without limitation, the defense
                                    of usury, nor will the operation of any of
                                    the terms of the Mortgage Note or the
                                    Mortgage, or the exercise of any right
                                    thereunder, render the Mortgage Note or
                                    Mortgage unenforceable, in whole or in
                                    part, or subject to any right of
                                    rescission, set-off, counterclaim or

                                    and no such right of rescission, set-off,
                                    counterclaim or defense has been asserted
                                    with respect thereto, other than any other
                                    state laws providing "security first"
                                    election of remedies, one action, and
                                    anti-deficiency requirements; and to the
                                    best of Loan Seller's knowledge, the
                                    Mortgagor was not a debtor in any state or
                                    federal bankruptcy or insolvency proceeding
                                    at the time the Mortgage Loan was
                                    originated;

                           (viii)   All buildings or other customarily insured
                                    improvements upon the Mortgaged Property
                                    are insured by an insurer acceptable under
                                    the FNMA Guides, against loss by fire,
                                    hazards of extended coverage and such other
                                    hazards as are provided for in the FNMA
                                    Guides or by FHLMC, as well as all
                                    additional requirements set forth in
                                    Section 3.13 hereof. All such standard
                                    hazard policies are in full force and
                                    effect and on the date of origination
                                    contained a standard mortgagee clause
                                    naming the Loan Seller and its successors
                                    in interest and assigns as loss payee and
                                    such clause is still in effect and all
                                    premiums due thereon have been paid. If
                                    required by the Flood Disaster Protection
                                    Act of 1973, as amended, the Mortgage Loan
                                    is covered by a flood insurance policy
                                    meeting the requirements of the current
                                    guidelines of the Federal Insurance
                                    Administration which policy conforms to
                                    FNMA and FHLMC requirements. Such policy
                                    was issued by an insurer acceptable under
                                    FNMA or FHLMC guidelines. The Mortgage
                                    obligates the Mortgagor thereunder to
                                    maintain all such insurance at the

                                    Mortgagor's cost and expense, and on the
                                    Mortgagor's failure to do so, authorizes
                                    the holder of the Mortgage to maintain such
                                    insurance at the Mortgagor's cost and
                                    expense and to seek reimbursement therefor
                                    from the Mortgagor;

                           (ix)     Any and all requirements of any federal,
                                    state or local law including, without
                                    limitation, usury, truth-in-lending, real
                                    estate settlement procedures, consumer
                                    credit protection, equal credit opportunity
                                    or disclosure laws applicable to the
                                    Mortgage Loan have been complied with;

                           (x)      The Mortgage has not been satisfied,
                                    canceled or subordinated, in whole or in
                                    part, or rescinded, and the Mortgaged
                                    Property has not been released from the
                                    lien of the Mortgage, in whole or in part
                                    nor has any instrument been executed that
                                    would effect any such release,
                                    cancellation, subordination or rescission.
                                    Neither the Loan Seller nor any servicer
                                    has waived the performance by the Mortgagor
                                    of any action, if the Mortgagor's failure
                                    to perform such action would cause the
                                    Mortgage Loan to be in default, nor has the
                                    Loan Seller nor any servicer waived any
                                    default resulting from any action or
                                    inaction by the Mortgagor;

                           (xi)     The Mortgage is a valid, subsisting,
                                    enforceable and perfected first lien on the
                                    Mortgaged Property, including all buildings
                                    on the Mortgaged Property and all
                                    installations and mechanical, electrical,
                                    plumbing, heating and air conditioning
                                    systems affixed to such buildings, and all
                                    additions, alterations and replacements
                                    made at any time with respect to the

                                    and encumbrances having priority over the

                                    the Mortgage Loan establishes and creates a
                                    valid, subsisting, enforceable and

                                    therein, and the Loan Seller had the full
                                    right to sell and assign the same to the
                                    Seller;

                           (xii)    The Mortgage Note and the related Mortgage
                                    are original and genuine and each is the
                                    legal, valid and binding obligation of the
                                    maker thereof, enforceable in all respects
                                    in accordance with its terms subject to
                                    bankruptcy, insolvency and other laws of
                                    general application affecting the rights of
                                    creditors. The Loan Seller has taken all
                                    action necessary to transfer such rights of
                                    enforceability to the Seller and the Trust.
                                    All parties to the Mortgage Note and the
                                    Mortgage had the legal capacity to enter
                                    into the Mortgage Loan and to execute and
                                    deliver the Mortgage Note and the Mortgage.
                                    The Mortgage Note and the Mortgage have
                                    been duly and properly executed by such
                                    parties. No fraud, error, omission,
                                    misrepresentation, negligence or similar

                                    has taken place on the part of Loan Seller
                                    or the Mortgagor or, to the best of the
                                    Loan Seller's knowledge, any other party
                                    involved in the origination of the Mortgage
                                    Loan. The proceeds of the Mortgage Loan
                                    have been fully disbursed and there is no
                                    requirement for future advances thereunder,
                                    and any and all requirements as to
                                    completion of any on-site or off-site
                                    improvements and as to disbursements of any
                                    escrow funds therefor have been complied
                                    with. All costs, fees and expenses incurred
                                    in making or closing the Mortgage Loan and

                                    Mortgage Loans pursuant to the Loan Sale
                                    Agreement, the Loan Seller was the sole

                                    or pledge, and the Loan Seller had good and
                                    marketable title to and was the sole owner

                                    the Loan Seller). The Loan Seller has no

                                    Agreement;

                           (xiv)    Each Mortgage Loan is covered by an ALTA

                                    issued by a title insurer acceptable to

                                    any Permitted Encumbrances) the Loan

                                    each month. The Mortgage contains the usual
                                    and enforceable provisions (subject to any
                                    applicable state, federal or local laws) of
                                    the originator at the time of origination
                                    for the acceleration of the payment of the
                                    unpaid principal amount of the Mortgage
                                    Loan if the related Mortgaged Property is
                                    sold without the prior consent of the
                                    mortgagee thereunder;

                           (xix)    The Mortgaged Property is not subject to
                                    any material damage by waste, fire,
                                    earthquake, windstorm, flood or other
                                    casualty and is in good repair. At
                                    origination of the Mortgage Loan there was,
                                    and there currently is, no proceeding

                                    There have not been any condemnation
                                    proceedings with respect to the Mortgaged
                                    Property and, to the best of Loan Seller's
                                    knowledge, there are no such proceedings
                                    scheduled to commence at a future date;

                           (xx)     The related Mortgage contains customary and
                                    enforceable provisions such as to render
                                    the rights and remedies of the holder
                                    thereof adequate for the realization
                                    against the Mortgaged Property of the
                                    benefits of the security provided thereby,
                                    including, (1) in the case of a Mortgage
                                    designated as a deed of trust, by trustee's
                                    sale, and (2) otherwise by judicial
                                    foreclosure. There is no homestead or other
                                    exemption available to the Mortgagor which
                                    would interfere with the right to sell the
                                    Mortgaged Property at a trustee's sale or
                                    the right to foreclose the Mortgage;

                           (xxi)    If the Mortgage constitutes a deed of
                                    trust, a trustee, authorized and duly
                                    qualified if required under applicable law
                                    to act as such, has been properly
                                    designated and currently so serves and is
                                    named in the Mortgage, and no fees or
                                    expenses are or will become payable by the
                                    Trust or any other Person to the trustee
                                    under the deed of trust, except in
                                    connection with a trustee's sale or
                                    attempted sale after default by the
                                    Mortgagor;

                           (xxii)   The Mortgage File contains an appraisal of
                                    the related Mortgaged Property signed prior
                                    to the final approval of the mortgage loan
                                    application by the appraiser, approved by
                                    the Loan Seller, who, to the best of Loan
                                    Seller's knowledge, had no interest, direct
                                    or indirect, in the Mortgaged Property or
                                    in any loan made on the security thereof,
                                    and whose compensation is not affected by
                                    the approval or disapproval of the Mortgage
                                    Loan, and the appraisal and appraiser both
                                    satisfy the requirements of FNMA or FHLMC

                           (xxviii) The Mortgage Loan is a fixed rate mortgage
                                    loan. The Mortgage Loan has an original
                                    term to maturity of not more than thirty
                                    (30) years, with interest payable in
                                    arrears on the first day of each month. The
                                    Mortgage Note requires a monthly payment
                                    which is sufficient to fully amortize the
                                    original principal balance over the
                                    original term thereof and to pay interest
                                    at the related Mortgage Interest Rate. The
                                    Mortgage Loan does not contain terms or
                                    provisions which would result in negative
                                    amortization.

                           (xxix)   The origination and servicing practices
                                    used by the Loan Seller, with respect to
                                    the Mortgage Note and Mortgage have been
                                    legal and in accordance with applicable
                                    laws and regulations, and in all material
                                    respects proper and prudent in the mortgage
                                    origination and servicing business. With
                                    respect to escrow deposits and payments
                                    that the Loan Seller is entitled to
                                    collect, all such payments are in the
                                    possession of, or under the control of, the
                                    Loan Seller, and there exist no
                                    deficiencies in connection therewith for
                                    which customary arrangements for repayment
                                    thereof have not been made. All escrow
                                    payments have been collected in full
                                    compliance with state and federal law and
                                    the provisions of the related Mortgage Note
                                    and Mortgage. If the Mortgage Loan is the
                                    subject of an escrow, escrow of funds is
                                    not prohibited by applicable law. No escrow
                                    deposits or other charges or payments due
                                    under the Mortgage Note have been
                                    capitalized under any Mortgage or the
                                    related Mortgage Note;

                           (xxx)    The Mortgage Loan did not have a
                                    Loan-to-Value Ratio at origination greater
                                    than 95%;

                           (xxxi)   In the event the Mortgage Loan has an LTV
                                    greater than 80%, the excess of the
                                    principal

                                    as to payment defaults by a Primary
                                    Mortgage Insurance Policy issued by a
                                    Qualified Mortgage Insurer. All provisions
                                    of such Primary Mortgage Insurance Policy
                                    have been and are being complied with, such
                                    policy is in full force and effect, and all
                                    premiums due thereunder have been paid. No
                                    action, inaction, or event has occurred and
                                    no state of facts exists that has, or will
                                    result in the exclusion from, denial of, or
                                    defense to coverage. Subject to the

                                    Insurance Policy obligates the Mortgagor
                                    thereunder to maintain the Primary Mortgage
                                    Insurance Policy and to pay all premiums
                                    and charges in connection therewith. The

                                    the Mortgagor is the owner of a valid and
                                    subsisting leasehold interest under such
                                    ground lease; (ii) such ground lease is in

                                    charges reserved therein have been fully
                                    paid to the extent payable as of the

                                    lease on the part of the lessor to be

                                    under such ground lease has satisfied any
                                    repair or construction obligations due as

                                    than those consents which have been
                                    obtained and are in full force and effect)

                                    provision of or cause a default under, such
                                    ground lease;

                           (xliii)  The Mortgage Loan is a "qualified mortgage"
                                    within the meaning of Section 860G(a)(3) of
                                    the Code (without regard to Treasury
                                    Regulations ss. 1.860G-2(f) or any similar
                                    rule that provides that a defective
                                    obligation is a qualified mortgage for a
                                    temporary period);

                                    under the lease holds a fee simple interest
                                    in the land;

                                    (2) the terms of such lease expressly
                                    permit the mortgaging of the leasehold
                                    estate, the assignment of the lease without
                                    the lessor's consent and the acquisition by
                                    the holder of the Mortgage of the rights of
                                    the lessee upon foreclosure or assignment
                                    in lieu of foreclosure or provide the
                                    holder of the Mortgage with substantially
                                    similar protections; (3) the terms of such
                                    lease do not (a) allow the termination
                                    thereof upon the lessee's default without
                                    the holder of the Mortgage being entitled
                                    to receive written notice of, and
                                    opportunity to cure, such default, (b)

                                    event of damage or destruction as long as
                                    the Mortgage is in existence, (c) prohibit
                                    the holder of the Mortgage from being
                                    insured (or receiving proceeds of
                                    insurance) under the hazard insurance
                                    policy or policies relating to the
                                    Mortgaged Property or (d) permit any
                                    increase in rent by the lessor other than
                                    pre-established increases set forth in the
                                    lease; (4) the original term of such lease
                                    is not less than 15 years; (5) the term of
                                    such lease does not terminate earlier than
                                    five years after the maturity date of the
                                    Mortgage Note; and (6) the Mortgaged
                                    Property is located in a jurisdiction in
                                    which the use of leasehold estates in
                                    transferring ownership in residential
                                    properties is a widely accepted practice;


         (B)      with respect to the Mortgage Loans in the aggregate:

                  (i)  Approximately 20% (by aggregate outstanding principal
         balance of the Mortgage Loans as of the Cut-off Date) of the Mortgage
         Loans are insured under Primary Mortgage Insurance Policies; and

                  (ii) No more than 1% of the Mortgaged Properties (by
         outstanding principal balance of the related Mortgage Loans as of the
         Cut-off Date) are secured by leasehold interests.

         It is understood and agreed that the representations and warranties
set forth in this Section 2.04 are the only representations and warranties of
the Loan Seller made with respect to the Mortgage Loans that are enforceable by
the Trustee for the Certificateholders. Upon the discovery by the Seller, the
Master Servicer, the Loan Seller or the Trustee of a breach of any of the



                                     -45-
<PAGE>   51

representations and warranties made in this Section 2.04(b) which materially
and adversely affects the interests of the Certificateholders of the applicable
Series in such Mortgage Loan and/or if the breach is one that, had it been
discovered before the Closing Date, would have prevented the Mortgage Loan from
being a "qualified mortgage" within the meaning of the REMIC Provisions, the
party discovering such breach shall give prompt written notice to the other
parties. The Loan Seller shall, within 90 days from the earlier of the date
that (x) the Seller, the Master Servicer or the Trustee notified the Loan
Seller of such breach, or (y) the Loan Seller discovered such breach, either
(i) cure such breach in all material respects or (ii) purchase such Mortgage
Loan from the applicable Trust Fund at the Purchase Price and in the manner set
forth in Section 2.02. Except as expressly set forth herein none of the
Trustee, the Seller or the Master Servicer (in its capacity as Master Servicer)
is under any obligation to discover any breach of the above mentioned
representations and warranties. It is understood and agreed that the obligation
of the Loan Seller to cure such breach or purchase such Mortgage Loan as to
which such a breach has occurred and is continuing shall constitute the sole
remedy respecting such breach available to the applicable Certificateholders or
the Trustee on behalf of such Certificateholders.

         2.05. Issuance of Certificates.

         The Trustee acknowledges the assignment to it of the Mortgage Loans
and the delivery of the Mortgage Files to it together with the assignment to it
of all other assets included in any Trust Fund for each Series, receipt of
which is hereby acknowledged. Concurrently with such delivery and in exchange
therefor, the Trustee, pursuant to the written request of the Seller executed
by an officer of the Seller has executed and caused to be authenticated and
delivered to, or upon the order of, the Seller the Certificates of each Series
in authorized denominations, each of which evidences ownership of the entire
Trust Fund with respect to such Series.


III              ADMINISTRATION AND SERVICING OF THE TRUST FUND

         3.01. Master Servicer to Act as Master Servicer.

         The Master Servicer shall service and administer the Mortgage Loans in
accordance with this Agreement, the related Mortgage Notes and Mortgages and
Accepted Servicing Practices, and shall have full power and authority, acting
alone and/or through Sub-Servicers as provided in Section 3.02, to do or cause
to be done any and all things in connection with such servicing and
administration that it may deem necessary or desirable and consistent with
Accepted Servicing Practices and the terms of this Agreement. Without limiting
the generality of the foregoing, the Master Servicer in its own name or in the
name of a Sub-Servicer is hereby authorized and empowered by the Trustee when
the Master Servicer believes it appropriate in its best judgment, to (i)
execute and deliver, on behalf of the applicable Certificateholders and the
Trustee or any of them, any and all instruments of satisfaction or
cancellation, or of partial or full release or discharge, and all other
comparable instruments, with respect to the Mortgage Loans and the Mortgaged
Properties, (ii) institute foreclosure proceedings or obtain a deed-in-lieu of
foreclosure so as to convert the ownership of such properties, and (iii) hold
or cause to be held title to such properties, on behalf of the Trustee and the
applicable Certificateholders. The Master Servicer shall service and administer
the Mortgage Loans in accordance with applicable state and federal law and
shall provide to the 




                                     -46-
<PAGE>   52


Mortgagors any reports required to be provided to them thereby. Subject to
Section 3.16, the Trustee shall execute based on the written request of the
Master Servicer and furnish to the Master Servicer and any Sub-Servicer any
special or limited powers of attorney and other documents necessary or
appropriate to enable the Master Servicer and any Sub-Servicer to carry out
their servicing and administrative duties hereunder. The Trustee shall not be
liable for any action taken by the Master Servicer or any Sub-Servicer pursuant
to the application of such special or limited powers of attorney.

         In accordance with the standards of the preceding paragraph, the
Master Servicer shall advance or cause to be advanced funds as necessary for
the purpose of effecting the payment of taxes and assessments on the Mortgaged
Properties, which advances shall be reimbursable in the first instance from
related collections from the Mortgagors pursuant to Section 3.09, and further
as provided in Section 3.11. No costs incurred by the Master Servicer or by
Sub-Servicers in effecting the payment of taxes and assessments on the
Mortgaged Properties shall, for the purpose of calculating distributions to
Certificateholders, be added to the amount owing under the related Mortgage
Loans, notwithstanding that the terms of such Mortgage Loans so permit.

         Notwithstanding anything in this Agreement to the contrary, the Master
Servicer shall not (unless the Mortgagor is in default with respect to the
Mortgage Loan or such default is, in the judgment of the Master Servicer,
reasonably foreseeable) make or permit any modification, waiver or amendment of
any term of any Mortgage Loan that would both (i) effect an exchange or
reissuance of such Mortgage Loan under Section 1001 of the Code (or Treasury
regulations promulgated thereunder) and (ii) cause either the Lower REMIC or
the Upper REMIC to fail to qualify as a REMIC under the Code or the imposition
of any tax on "prohibited transactions" or "contributions" after the Startup
Day under the REMIC Provisions.

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

         3.02. Sub-Servicing Agreements Between Master Servicer and
               Sub-Servicers.

                  (a)      The Master Servicer may enter into Sub-Servicing
                           Agreements with Sub-Servicers for the servicing and
                           administration of the Mortgage Loans and for the
                           performance of any and all other activities of the
                           Master Servicer hereunder. Each Sub-Servicer shall
                           be either (i) an institution the accounts of which
                           are insured by the FDIC or (ii) another entity that
                           engages in the business of originating or servicing
                           mortgage loans, and in either case shall be
                           authorized to transact business in the state or
                           states in which the related Mortgaged Properties it
                           is to service are situated, if and to the extent
                           required by applicable law to enable the
                           Sub-Servicer to perform its obligations hereunder
                           and under the Sub-Servicing Agreement, and in either
                           case shall be a FHLMC or FNMA approved mortgage
                           servicer. Any Subservicing Agreement entered into by
                           the Master Servicer shall include the provision that
                           such Subservicing Agreement may be


                                     -47-

<PAGE>   53


                           immediately terminated without cause and without any
                           termination fee by any successor Master Servicer
                           hereunder. In addition, each SubServicing Agreement
                           must impose on the Sub-Servicer requirements
                           conforming to the provisions set forth in Section
                           3.08 and provide for servicing of the Mortgage Loans
                           consistent with the terms of this Agreement. With
                           the consent of the Trustee, which consent shall not
                           be unreasonably withheld, the Master Servicer and
                           the Sub-Servicers may enter into Sub-Servicing
                           Agreements and make amendments to the Sub-Servicing
                           Agreements or enter into different forms of
                           Sub-Servicing Agreements; provided, however, that
                           any such amendments or different forms shall be
                           consistent with and not violate the provisions of
                           this Agreement, and that no such amendment or
                           different form shall be made or entered into which
                           could be reasonably expected to be materially
                           adverse to the interests of the Certificateholders
                           of a Series, without the consent of the Holders of
                           Certificates of such Series evidencing Fractional
                           Undivided Interests aggregating not less than
                           662/3%.

                  (b)      As part of its servicing activities hereunder, the
                           Master Servicer, for the benefit of the Trustee and
                           the Certificateholders, shall enforce the
                           obligations of each Sub-Servicer under the related
                           Sub-Servicing Agreement, including, without
                           limitation, any obligation to make advances in
                           respect of delinquent payments as required by a
                           Sub-Servicing Agreement. Such enforcement,
                           including, without limitation, the legal prosecution
                           of claims, termination of Sub-Servicing Agreements
                           and the pursuit of other appropriate remedies, shall
                           be in such form and carried out to such an extent
                           and at such time as the Master Servicer, in its good
                           faith business judgment, would require were it the
                           owner of the related Mortgage Loans. The Master
                           Servicer shall pay the costs of such enforcement at
                           its own expense, but shall be reimbursed therefor
                           only (i) from a general recovery resulting from such
                           enforcement only to the extent, if any, that such
                           recovery exceeds all amounts due in respect of the
                           related Mortgage Loans or (ii) from a specific
                           recovery of costs, expenses or attorneys' fees
                           against the party against whom such enforcement is
                           directed.

         3.03. Successor Sub-Servicers.

         The Master Servicer shall be entitled to terminate any Sub-Servicing
Agreement and the rights and obligations of any Sub-Servicer pursuant to any
Sub-Servicing Agreement in accordance with the terms and conditions of such
Sub-Servicing Agreement. In the event of termination of any Sub-Servicer, all
servicing obligations of such Sub-Servicer shall be assumed simultaneously by
the Master Servicer without any act or deed on the part of such Sub-Servicer or
the Master Servicer, and the Master Servicer either shall service directly the
related Mortgage Loans or shall enter into a SubServicing Agreement with a
successor Sub-Servicer which qualifies under Section 3.02. Each Sub-


                                     -48-
<PAGE>   54


Servicing Agreement, if any, shall include the provision that such agreement
may be immediately terminated by any successor Master Servicer without cause
and without payment of any fee or penalty in the event that the Master Servicer
shall, for any reason, no longer be the Master Servicer (including by reason of
an Event of Default).

         3.04. Liability of the Master Servicer.

         Notwithstanding any Sub-Servicing Agreement, any of the provisions of
this Agreement relating to agreements or arrangements between the Master
Servicer and a Sub-Servicer or reference to actions taken through a
Sub-Servicer or otherwise, the Master Servicer shall remain obligated and
primarily liable to the Trustee and Certificateholders for the servicing and
administering of the Mortgage Loans in accordance with the provisions of
Section 3.01 without diminution of such obligation or liability by virtue of
such Sub-Servicing Agreements or arrangements or by virtue of indemnification
from the Sub-Servicer and to the same extent and under the same terms and
conditions as if the Master Servicer alone were servicing and administering the
Mortgage Loans. For purposes of this Agreement, the Master Servicer shall be
deemed to have received payments on Mortgage Loans when the Sub-Servicer has
received such payments. The Master Servicer shall be entitled to enter into any
agreement with a Sub-Servicer for indemnification of the Master Servicer by
such Sub-Servicer and nothing contained in this Agreement shall be deemed to
limit or modify such indemnification.

         3.05. No Contractual Relationship Between Sub-Servicers and Trustee or
               Certificateholders.

         Any Sub-Servicing Agreement that may be entered into and any
transactions or services relating to the Mortgage Loans involving a
Sub-Servicer in its capacity as such and not as an originator shall be deemed
to be between the Sub-Servicer and the Master Servicer alone, and the Trustee
and Certificateholders shall not be deemed parties thereto and shall have no
claims, rights, obligations, duties or liabilities with respect to the
Sub-Servicer except as set forth in Section 3.06.

         3.06. Assumption or Termination of Sub-Servicing Agreements by
               Trustee.

         In the event the Master Servicer shall for any reason no longer be the
master servicer (including by reason of an Event of Default) hereunder, the
Trustee, its designee or the successor Master Servicer for the Trustee shall
thereupon assume all of the rights and obligations of the Master Servicer under
each Sub-Servicing Agreement that the Master Servicer may have entered into,
unless the Trustee is then permitted and elects to terminate any Sub-Servicing
Agreement in accordance with its terms. Subject to Section 3.03, the Trustee,
its designee or the successor Master Servicer for the Trustee shall be deemed
to have assumed all of the Master Servicer's interest therein and to have
replaced the Master Servicer as a party to each Sub-Servicing Agreement to the
same extent as if the Sub-Servicing Agreements had been assigned to the
assuming party, except that the Master Servicer shall not thereby be relieved
of any liability or obligations under the Sub-Servicing Agreements, and the
Master Servicer shall continue to be entitled to any rights or benefits which
arose prior to its termination as master servicer.



                                     -49-
<PAGE>   55

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

         3.07. Collection of Certain Mortgage Loan Payments.

         The Master Servicer shall use reasonable efforts to collect all
payments due under each Mortgage Loan when the same shall become due and
payable and shall, to the extent such procedures shall be consistent with this
Agreement, Accepted Servicing Practices, and the terms and provisions of any
related Primary Mortgage Insurance Policy or any other related Insurance
Policy, follow such collection procedures as it follows with respect to
mortgage loans comparable to the Mortgage Loans and held for its own account.
The Master Servicer shall not be required to institute or join in litigation
with respect to collection of any payment (whether under a Mortgage, Mortgage
Note, Primary Hazard Insurance Policy or otherwise or against any public or
governmental authority with respect to a taking or condemnation) if it
reasonably believes that it is prohibited by applicable law from enforcing the
provision of the Mortgage or other instrument pursuant to which such payment is
required. Consistent with the foregoing, the Master Servicer may in its
discretion (i) waive any prepayment charge, assumption fee, late payment charge
or other charge in connection with a Mortgage Loan, and (ii) arrange a
schedule, running for no more than 180 days after the Due Date for payment of
any installment on any Mortgage Note, for the liquidation of delinquent items.
The Master Servicer shall be responsible for preparing and distributing all
information statements relating to payments on the Mortgage Loans, in
accordance with all applicable federal and state tax laws and regulations.

         3.08. Sub-Servicing Accounts.

         In those cases where a Sub-Servicer is servicing a Mortgage Loan
pursuant to a SubServicing Agreement, the Sub-Servicer will be required to
establish and maintain one or more accounts (collectively, the "Sub-Servicing
Account"). The Sub-Servicing Account shall be an Eligible Account and shall
otherwise be acceptable to the Master Servicer. All amounts held in a
Sub-Servicing Account shall be held in trust for the Trustee for the benefit of
the Certificateholders. The Sub-Servicer will be required to deposit into the
Sub-Servicing Account on a daily basis, but in no event later than the first
Business Day after receipt of all proceeds of the Mortgage Loans received by
the Sub-Servicer, less its servicing compensation and any unreimbursed expenses
and advances, to the extent permitted by the Sub-Servicing Agreement. On each
Sub-Servicer Remittance Date the Sub-Servicer will be required to remit to the
Master Servicer all funds held in the Sub-Servicing Account with respect to any
Mortgage Loan as of the Sub-Servicer Remittance Date, after deducting from such
remittance an amount equal to the servicing compensation and unreimbursed
expenses and advances to which it is then entitled pursuant to the related
SubServicing Agreement, to the extent not previously paid to or retained by it.
In addition, on each SubServicer Remittance Date the Sub-Servicer will be
required to remit to the Master Servicer any amounts required to be advanced
pursuant to the related Sub-Servicing Agreement. The Sub-Servicer will also be
required to remit to the Master Servicer, within one Business Day of receipt,









                                     -50-

the proceeds of any Principal Prepayment made by the Mortgagor and any
Insurance Proceeds or Liquidation Proceeds.

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

         The Master Servicer and the Sub-Servicers shall establish and maintain
one or more accounts (the "Servicing Accounts"), and shall deposit and retain
therein all collections from the Mortgagors (or related advances from
Sub-Servicers) for the payment of taxes, assessments, Primary Hazard Insurance
Policy and Primary Mortgage Insurance Policy premiums, and comparable items for
the account of the Mortgagors, to the extent that the Master Servicer
customarily escrows for such amounts. Withdrawals of amounts so collected from
a Servicing Account may be made only to (i) effect payment of taxes,
assessments, Primary Hazard Insurance Policy and Primary Mortgage Insurance
Policy premiums and comparable items; (ii) reimburse the Master Servicer (or a
SubServicer to the extent provided in the related Sub-Servicing Agreement) out
of related collections for any payments made pursuant to Sections 3.01 (with
respect to taxes and assessments), 3.13 (with respect to Primary Hazard
Insurance Policies) and 3.25 (with respect to Primary Mortgage Insurance only);
(iii) refund to Mortgagors any sums as may be determined to be overages; (iv)
clear and terminate the Servicing Account at the termination of this Agreement
pursuant to Section 9.01 or (v) to withdraw any amounts deposited therein that
were not required to be so deposited. As part of its servicing duties, the
Master Servicer or Sub-Servicers shall, if and to the extent required by law,
pay to the Mortgagors interest on funds in Servicing Accounts from its or their
own funds, without any reimbursement therefor.

         3.10. Custodial Account.

                  (a)      The Master Servicer shall establish and maintain one
                           or more accounts as the Custodial Account in which
                           the Master Servicer shall deposit or cause to be
                           deposited on a daily basis, or as and when received
                           from the Sub-Servicers, the following payments and
                           collections received or made by or on behalf of it
                           subsequent to the Cut-off Date, or received by it
                           prior to the Cut-off Date but allocable to a period
                           subsequent thereto (other than in respect of
                           principal and interest on the Mortgage Loans due on
                           or before the Cut-off Date):

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

                                    (ii)     all payments on account of
                                             interest on the Mortgage Loans,
                                             exclusive of any portion thereof
                                             representing interest in excess of
                                             the related Net Mortgage Rate;

                                    (iii)    all Insurance Proceeds (other than
                                             proceeds that represent
                                             reimbursement of costs and
                                             expenses incurred by the Master

                                             claims under the related Insurance
                                             Policies), Liquidation Proceeds
                                             and REO Proceeds;

                                    (iv)     all proceeds of any Mortgage Loan
                                             or REO Property repurchased or
                                             purchased in accordance with
                                             Sections 2.02, 2.04, 3.22 or 9.01;
                                             and

                                    (v)      any amounts required to be
                                             deposited pursuant to Section 3.12
                                             or 3.13.

         The foregoing requirements for deposit in the Custodial Account shall
be exclusive. In the event the Master Servicer shall deposit in the Custodial
Account any amount not required to be deposited therein, it may withdraw such
amount from the Custodial Account, any provision herein to the contrary
notwithstanding. The Custodial Account shall be maintained as a segregated
account, separate and apart from trust funds created for mortgage pass-through
certificates of other series, and the other accounts of the Master Servicer.

                  (b)      Funds in the Custodial Account may be invested in
                           Permitted Instruments in accordance with the
                           provisions set forth in Section 3.12. The Master
                           Servicer shall give notice to the Trustee and the
                           Seller of the location of the Custodial Account
                           after any change thereof.

         3.11. Permitted Withdrawals From the Custodial Account.

         The Master Servicer may, from time to time as provided herein, make
withdrawals from the Custodial Account of amounts on deposit therein pursuant
to Section 3.10 that are attributable to the Mortgage Loans for the following
purposes:

                                    (i)      to make deposits into the

                                             may be, with respect to each

                                             been purchased or repurchased
                                             pursuant to Sections 2.02, 2.04 or

                                             and not yet distributed as of the

                                             prosecution of any claims pursuant
                                             to Sections 3.13 or 3.25 that are
                                             in excess of the amounts so
                                             recovered;

                                    (vi)     to reimburse itself or any
                                             Sub-Servicer for unpaid Servicing
                                             Fees and unreimbursed Servicing
                                             Advances, the Master Servicer's or
                                             any Sub-Servicer's right to
                                             reimbursement pursuant to this
                                             clause (vi) with respect to any
                                             Mortgage Loan being limited to
                                             late recoveries of the payments
                                             for which such advances were made
                                             pursuant to Section 3.01 or
                                             Section 3.09 and any other related
                                             Late Collections;

                                    (vii)    to pay itself as servicing
                                             compensation (in addition to the
                                             Servicing Fee), on or after each
                                             Distribution Date, any interest or
                                             investment income earned on funds
                                             deposited in the Custodial Account
                                             for the period ending on such
                                             Distribution Date, subject to
                                             Section 8.05 and 3.23;

                                    (viii)   to reimburse itself or any
                                             Sub-Servicer for any Advance
                                             previously made which the Master
                                             Servicer has determined to be a
                                             Nonrecoverable Advance, provided
                                             that such Advance was made with
                                             respect to a 



                                     -53-
<PAGE>   59

                                             delinquency that ultimately
                                             constituted an Excess Special
                                             Hazard Loss, Excess Fraud Loss, 
                                             Excess Bankruptcy Loss or
                                             Extraordinary Loss; and

                                    (ix)     to clear and terminate the
                                             Custodial Account at the
                                             termination of this Agreement
                                             pursuant to Section 9.01.

         The Master Servicer shall keep and maintain separate accounting
records on a Mortgage Loan by Mortgage Loan basis, for the purpose of
justifying any withdrawal from the Custodial Account pursuant to such clauses
(ii), (iii), (iv), (v), (vi), and (viii).

         3.12. Permitted Instruments.

         Any institution maintaining the Custodial Account shall at the
direction of the Master Servicer invest the funds in such account in Permitted
Instruments, each of which shall mature not later than the Business Day
immediately preceding the Certificate Account Deposit Date next following the
date of such investment (except that if such Permitted Instrument is an
obligation of the institution that maintains such account, then such Permitted
Instrument shall mature not later than such Certificate Account Deposit Date)
and shall not be sold or disposed of prior to its maturity. All income and gain
realized from any such investment as well as any interest earned on deposits in
the Custodial Account shall be for the benefit of the Master Servicer, subject
to Section 3.23. The Master Servicer shall deposit in the Custodial Account
(with respect to investments made hereunder of funds held therein) an amount
equal to the amount of any loss incurred in respect of any such investment
immediately upon realization of such loss without right of reimbursement.

         3.13. Maintenance of Primary Hazard Insurance.

         The Master Servicer shall cause to be maintained for each Mortgage
Loan primary hazard insurance with extended coverage on the related Mortgaged
Property in an amount equal to the replacement value of the improvements, as
determined by the insurance company, on such Mortgaged Property. The Master
Servicer shall also cause to be maintained on property acquired upon
foreclosure, or deed in lieu of foreclosure, of any Mortgage Loan, fire
insurance with extended coverage in an amount equal to the replacement value of
the improvements thereon. Pursuant to Section 3.10, any amounts collected by
the Master Servicer under any such policies (other than amounts to be applied
to the restoration or repair of the related Mortgaged Property or property thus
acquired or amounts released to the Mortgagor in accordance with the Master
Servicer's normal servicing procedures) shall be deposited in the Custodial
Account, subject to withdrawal pursuant to Section 3.11. Any cost incurred by
the Master Servicer in maintaining any such insurance shall not, for the
purpose of calculating monthly distributions to Certificateholders, be added to
the amount owing under the Mortgage Loan, notwithstanding that the terms of the
Mortgage Loan so permit. It is understood and agreed that no earthquake or
other additional insurance is to be required of any Mortgagor or maintained on
property acquired in respect of a Mortgage Loan other than pursuant to such
applicable laws and regulations as shall at any time be in force and as shall
require such additional insurance. Whenever the improvements securing a
Mortgage Loan are located in a 








                                     -54-
<PAGE>   60

federally designated special flood hazard area, the Master Servicer shall cause
flood insurance (to the extent available) to be maintained in respect thereof.
Such flood insurance shall be in an amount equal to the lesser of (i) the
replacement value of the improvements, which are part of such Mortgaged
Property on a replacement cost basis and (ii) the maximum amount of such
insurance available for the related Mortgaged Property under the national flood
insurance program (assuming that the area in which such Mortgaged Property is
located is participating in such program).

         In the event that the Master Servicer shall obtain and maintain a
blanket fire insurance policy with extended coverage insuring against hazard
losses on all of the Mortgage Loans, it shall conclusively be deemed to have
satisfied its obligations as set forth in the first two sentences of this
Section 3.13, it being understood and agreed that such policy may contain a
deductible clause, in which case the Master Servicer shall, in the event that
there shall not have been maintained on the related Mortgaged Property a policy
complying with the first two sentences of this Section 3.13 and there shall
have been a loss which would have been covered by such policy, deposit in the
Certificate Account the amount not otherwise payable under the blanket policy
because of such deductible clause. Any such deposit by the Master Servicer
shall be made on the Certificate Account Deposit Date next preceding the
Distribution Date which occurs in the month following the month in which
payments under any such policy would have been deposited in the Custodial
Account. In connection with its activities as administrator and servicer of the
Mortgage Loans, the Master Servicer agrees to present, on behalf of itself, the
Trustee and Certificateholders, claims under any such blanket policy.

         3.14. Enforcement of Due-on-Sale Clauses; Assumption Agreements.

         The Master Servicer will, to the extent it has knowledge of any
conveyance or prospective conveyance by any Mortgagor of the Mortgaged Property
(whether by absolute conveyance or by contract of sale, and whether or not the
Mortgagor remains or is to remain liable under the Mortgage Note or the
Mortgage), exercise or cause to be exercised its rights to accelerate the
maturity of such Mortgage Loan under any "due-on-sale" clause applicable
thereto; provided, however, that the Master Servicer shall not exercise any
such rights if it reasonably believes that it is prohibited by law from doing
so or such exercise would result in the loss of insurance coverage under any
related Insurance Policy. If the Master Servicer is unable to enforce such
"due-on-sale" clause (as provided in the previous sentence) or if no
"due-on-sale" clause is applicable, the Master Servicer or the SubServicer will
enter into an assumption and modification agreement with the Person to whom
such property has been conveyed or is proposed to be conveyed, pursuant to
which such Person becomes liable under the Mortgage Note and, to the extent
permitted by applicable state law, the Mortgagor remains liable thereon;
provided, however, that the Master Servicer shall not enter into any assumption
and modification agreement if the coverage provided under the Primary Mortgage
Insurance Policy, if any, would be impaired by doing so. The Master Servicer is
also authorized, with the approval of the insurer under any related Primary
Mortgage Insurance Policy, to enter into a substitution of liability agreement
with such Person, pursuant to which the original Mortgagor is released from
liability and such Person is substituted as the Mortgagor and becomes liable
under the Mortgage Note. Any fee collected by or on behalf of the Master
Servicer for entering into an assumption or substitution of liability agreement
will be retained by or on behalf of the Master Servicer as additional servicing
compensation. In connection with any such assumption, no material term of the
Mortgage Note (including but not limited to the Mortgage Rate, the amount of
the 








                                     -55-
<PAGE>   61

Monthly Payment, and any other term affecting the amount or timing of payment
on the Mortgage Loan) may be changed. The Master Servicer shall not enter into
any substitution or assumption if such substitution or assumption shall (i)
both constitute a "significant modification" effecting an exchange or
reissuance of such Mortgage Loan under the Code (or Treasury regulations
promulgated thereunder) and cause either the Upper REMIC or the Lower REMIC to
fail to qualify as a REMIC under the REMIC Provisions or (ii) cause the
imposition of any tax on "prohibited transactions" or "contributions" after the
Startup Day under the REMIC Provisions. The Master Servicer shall notify the
Trustee that any such substitution or assumption agreement has been completed
by forwarding to the Trustee the original copy of such substitution or
assumption agreement, which copy shall be added to the related Mortgage File
and shall, for all purposes, be considered a part of such Mortgage File to the
same extent as all other documents and instruments constituting a part thereof.

         Notwithstanding the foregoing paragraph or any other provision of this
Agreement, the Master Servicer shall not be deemed to be in default, breach or
any other violation of its obligations hereunder by reason of any assumption of
a Mortgage Loan by operation of law or any assumption that the Master Servicer
may be restricted by law from preventing, for any reason whatsoever, or if the
exercise of such right would impair or threaten to impair any recovery under
any applicable Insurance Policy. For purposes of this Section 3.14, the term
"assumption" is deemed to also include a sale of a Mortgaged Property that is
not accompanied by an assumption or substitution of liability agreement.

         3.15. Realization Upon Defaulted Mortgage Loans.

         The Master Servicer shall exercise reasonable efforts, consistent with
the terms of the related Mortgage, the Mortgage Note and Accepted Servicing
Practices, to foreclose upon or otherwise comparably convert (which may include
an REO Acquisition) the ownership of properties securing such of the Mortgage
Loans as come into and continue in default and as to which no satisfactory
arrangements can be made for collection of delinquent payments pursuant to
Section 3.07, and which are not released from the applicable Trust Fund
pursuant to any other provision hereof. The Master Servicer shall use
reasonable efforts to realize upon such defaulted Mortgage Loans in such manner
as will maximize the receipt of principal and interest by Certificateholders,
taking into account, among other things, the timing of foreclosure proceedings.
The foregoing is subject to the provisions that, in any case in which Mortgaged
Property shall have suffered damage from an Uninsured Cause, the Master
Servicer shall not be required to expend its own funds toward the restoration
of such property unless it shall determine in its sole discretion (i) that such
restoration will increase the net proceeds of liquidation of the related
Mortgage Loan to the applicable Certificateholders after reimbursement to
itself for such expenses, and (ii) that such expenses will be recoverable by
the Master Servicer through Insurance Proceeds or Liquidation Proceeds from the
related Mortgaged Property, as contemplated in Section 3.11. The Master
Servicer shall be responsible for all other costs and expenses incurred by it
in any such proceedings; provided, however, that it shall be entitled to
reimbursement thereof from the related property, as contemplated in Section
3.11.

         The proceeds of any Cash Liquidation or REO Disposition, as well as
any recovery resulting from a partial collection of Insurance Proceeds or
Liquidation Proceeds or any income from an REO Property, will be applied in the
following order of priority: first, to reimburse the Master Servicer or any
Sub-Servicer for any related unreimbursed Servicing Advances, pursuant to
Section 3.11(vi) 








                                     -56-
<PAGE>   62

or 3.22; second, to accrued and unpaid interest on the Mortgage Loan or REO
Imputed Interest, at the Mortgage Rate, to the last day of the month in which
the Cash Liquidation or REO Disposition occurred, or to the Due Date prior to
the Distribution Date on which such amounts are to be distributed if not in
connection with a Cash Liquidation or REO Disposition; and third, as a recovery
of principal of the Mortgage Loan. If the amount of the recovery so allocated
to interest is less than a full recovery thereof, that amount will be allocated
as follows: first, to unpaid Servicing Fees; and second, to interest at the Net
Mortgage Rate. The portion of the recovery so allocated to unpaid Servicing
Fees shall be reimbursed to the Master Servicer or any Sub-Servicer pursuant to
Section 3.11(vi). The portions of the recovery so allocated to interest at the
Net Mortgage Rate and to principal of the Mortgage Loan shall be applied as
follows: first, to reimburse the Master Servicer or any Sub-Servicer for any
related unreimbursed Advances in accordance with Section 3.11(iii) or 3.22, and
second, for distribution in accordance with the provisions of Section 4.01(b),
subject to Section 3.22 with respect to certain recoveries from an REO
Disposition constituting Excess Proceeds.

         3.16. Trustee to Cooperate; Release of Mortgage Files.

         Upon the payment in full of any Mortgage Loan, the Master Servicer
will immediately notify the Trustee by a certification (which certification
shall include a statement to the effect that all amounts received in connection
with such payment which are required to be deposited in the Custodial Account
pursuant to Section 3.10 have been so deposited) of a Servicing Officer and
shall request delivery to it of the Mortgage File in the form of the Request
for Release attached hereto as Exhibit D-2. Upon receipt of such certification
and request, the Trustee shall promptly release the related Mortgage File to
the Master Servicer. Subject to the receipt by the Master Servicer of the
proceeds of such payment in full and the payment of all related fees and
expenses, the Master Servicer shall arrange for the release to the Mortgagor of
the original canceled Mortgage Note. All other documents in the Mortgage File
shall be retained by the Master Servicer to the extent required by applicable
law. No expenses incurred in connection with any instrument of satisfaction or
deed of reconveyance shall be chargeable to the Custodial Account, the Excess
Proceeds Account or the Certificate Account.

         From time to time and as appropriate for the servicing or foreclosure
of any Mortgage Loan, including, for this purpose, collection under any
insurance policy relating to the Mortgage Loan, the Trustee shall, upon request
of the Master Servicer and delivery to the Trustee of a Request for Release in
the form attached hereto as Exhibit D-1, release the related Mortgage File to
the Master Servicer, and the Trustee shall execute such documents as the Master
Servicer shall prepare and request as being necessary to the prosecution of any
such proceedings. Such Request for Release shall obligate the Master Servicer
to return each document previously requested from the Mortgage File to the
Trustee when the need therefor by the Master Servicer no longer exists, unless
the Mortgage Loan has been liquidated and the Liquidation Proceeds relating to
the Mortgage Loan have been deposited in the Custodial Account or the Mortgage
File or such document has been delivered to an attorney, or to a public trustee
or other public official as required by law, for purposes of initiating or
pursuing legal action or other proceedings for the foreclosure of the Mortgaged
Property either judicially or non-judicially, and the Master Servicer has
delivered to the Trustee a certificate of a Servicing Officer certifying as to
the name and address of the Person to which such Mortgage File or such document
was delivered and the purpose or purposes of such delivery. Upon receipt of







                                     -57-
<PAGE>   63

a certification of a Servicing Officer in the form of the Request for Release
attached hereto as Exhibit D-1, stating that such Mortgage Loan was liquidated
and that all amounts received or to be received in connection with such
liquidation which are required to be deposited into the Custodial Account have
been or will be so deposited, or that such Mortgage Loan has become an REO
Property, a copy of such Request for Release shall be released by the Trustee
to the Master Servicer.

         Upon written request of a Servicing Officer, the Trustee shall execute
and deliver to the Master Servicer any court pleadings, requests for trustee's
sale or other documents prepared by the Master Servicer that are necessary to
the foreclosure or trustee's sale in respect of a Mortgaged Property or to any
legal action brought to obtain judgment against any Mortgagor on the Mortgage
Note or Mortgage or to obtain a deficiency judgment, or to enforce any other
remedies or rights provided by the Mortgage Note or Mortgage or otherwise
available at law or in equity. Each such request that such pleadings or
documents be executed by the Trustee shall include a certification as to the
reason such documents or pleadings are required and that the execution and
delivery thereof by the Trustee will not invalidate or otherwise affect the
lien of the Mortgage, except for the termination of such a lien upon completion
of the foreclosure or trustee's sale.

         3.17. Servicing Compensation.

         As compensation for its activities hereunder, the Master Servicer
shall be entitled to retain, from amounts representing payments or recoveries
of interest, the Servicing Fee with respect to each Mortgage Loan (less any
portion of such amounts retained by any Sub-Servicer). In addition, the Master
Servicer shall be entitled to recover unpaid Servicing Fees out of related Late
Collections to the extent permitted in Section 3.11.

         The Master Servicer also shall be entitled pursuant to Section 3.11 to
receive from the Custodial Account as additional servicing compensation
interest or other income earned on deposits therein, subject to Section 3.23,
all ancillary fees, including but not limited to any assumption fees,
reconveyance fees, prepayment fees and late fees, but only to the extent such
fees are collected by the Master Servicer and are in excess of any other
amounts due and payable with respect to the related Mortgage Loan. The Master
Servicer shall be required to pay all expenses incurred by it in connection
with its servicing activities hereunder (including payment of the premiums for
any blanket policy insuring against hazard losses pursuant to Section 3.13,
servicing compensation of the Sub-Servicer to the extent not retained by it and
the fees and expenses of the Trustee), and shall not be entitled to
reimbursement therefor except as specifically provided in Section 3.11. The
Servicing Fee may not be transferred in whole or in part except in connection
with the transfer of all of the Master Servicer's responsibilities and
obligations under this Agreement.

         3.18. Maintenance of Certain Servicing Policies.

         During the term of its service as Master Servicer, the Master Servicer
shall maintain in force (i) a policy or policies of insurance covering errors
and omissions in the performance of its obligations as servicer hereunder and
(ii) a fidelity bond in respect of its officers, employees or agents. Each such
policy or policies and bond shall, together, comply with the requirements from
time to time of FNMA or FHLMC for persons performing servicing for mortgage
loans purchased by such corporation. The Master Servicer shall prepare and
present, on behalf of itself, the Trustee 








                                     -58-
<PAGE>   64

and Certificateholders, claims under any such errors and omissions policy or
policies or fidelity bond in a timely fashion in accordance with the terms of
such policy or bond, and upon the filing of any claim on any policy or bond
described in this Section, the Master Servicer shall promptly notify the
Trustee of any such claims and the Trustee shall notify each Rating Agency of
such claim.

         3.19. Annual Statement as to Compliance.

         The Master Servicer will deliver to the Trustee and the Seller on or
before April 30th of each year, beginning with April 30, 1998, an Officers'
Certificate stating, as to each signatory thereof, that (i) a review of the
activities of the Master Servicer during the preceding fiscal year and of its
performance under this Agreement has been made under such officers'
supervision, and (ii) to the best of such officers' knowledge, based on such
review, the Master Servicer has fulfilled all of its obligations under this
Agreement throughout such year, or, if there has been a default in the
fulfillment of any such obligation, specifying each such default known to such
officers and the nature and status thereof.

         3.20. Annual Independent Public Accountants' Servicing Statement.

         On or before April 30th of each year, beginning with April 30, 1998,
the Master Servicer at its expense shall furnish to the Seller, the Trustee and
the Loan Seller (i) an opinion by a firm of independent certified public
accountants on the financial position of the Master Servicer at the end of its
fiscal year and the results of operations and changes in financial position of
the Master Servicer for such year then ended on the basis of an examination
conducted in accordance with generally accepted auditing standards, and (ii) if
the Master Servicer is then servicing any Mortgage Loans, a statement from such
independent certified public accountants to the effect that based on an
examination of certain specified documents and records relating to the
servicing of the Master Servicer's mortgage loan portfolio conducted
substantially in compliance with the audit program for mortgages serviced for
FNMA and FHLMC, the United States Department of Housing and Urban Development
Mortgage Audit Standards, or the Uniform Single Attestation Program for
Mortgage Bankers (the "Applicable Accounting Standards"), such firm is of the
opinion that such servicing has been conducted in compliance with the
Applicable Accounting Standards except for (a) such exceptions as such firm
shall believe to be immaterial and (b) such other exceptions as shall be set
forth in such statement. In rendering such statement, such firm may rely, as to
matters relating to direct servicing of mortgage loans by Sub-Servicers, upon
comparable statements for examinations conducted substantially in compliance
with the Uniform Single Attestation Program for Mortgage Bankers or the audit
program for mortgages serviced for FHLMC (rendered within one year of such
statement) of independent public accountants with respect to the related
Sub-Servicer. Copies of such statement shall be provided by the Trustee to any
Certificateholder upon request at the Master Servicer's expense, provided such
statement is delivered by the Master Servicer to the Trustee.

         3.21. Access to Certain Documentation.

                  (a)      The Master Servicer shall provide to the OTS, the
                           FDIC and other federal banking regulatory agencies,
                           and their respective examiners, access to the
                           documentation regarding the Mortgage Loans required
                           by applicable regulations of the OTS, the FDIC and
                           such other 



                                     -59-
<PAGE>   65


                           agencies. Such access shall be afforded without
                           charge, but only upon reasonable and prior written
                           request and during normal business hours at the
                           offices of the Master Servicer designated by it.
                           Nothing in this Section shall derogate from the
                           obligation of the Master Servicer to observe any
                           applicable law prohibiting disclosure of information
                           regarding the Mortgagors and the failure of the
                           Master Servicer to provide access as provided in
                           this Section as a result of such obligation shall
                           not constitute a breach of this section.

                  (b)      The Master Servicer shall afford the Seller and the
                           Trustee, upon reasonable notice, during normal
                           business hours access to all records maintained by
                           the Master Servicer in respect of its rights and
                           obligations hereunder and access to officers of the
                           Master Servicer responsible for such obligations.
                           Upon request, the Master Servicer shall furnish the
                           Seller and the Trustee with its most recent
                           financial statements and such other information as
                           the Master Servicer possesses regarding its
                           business, affairs, property and condition, financial
                           or otherwise to the extent related to the servicing
                           of the Mortgage Loans. The Seller may, but is not
                           obligated to, enforce the obligations of the Master
                           Servicer hereunder and may, but is not obligated to,
                           perform, or cause a designee to perform, any
                           defaulted obligation of the Master Servicer
                           hereunder or exercise the rights of the Master
                           Servicer hereunder; provided that the Master
                           Servicer shall not be relieved of any of its
                           obligations hereunder by virtue of such performance
                           by the Seller or its designee. The Seller shall not
                           have any responsibility or liability for any action
                           or failure to act by the Master Servicer and is not
                           obligated to supervise the performance of the Master
                           Servicer under this Agreement or otherwise.

         3.22. Title, Conservation and Disposition of REO Property.

         This Section shall apply only to REO Properties acquired for the
account of any Trust Fund, and shall not apply to any REO Property relating to
a Mortgage Loan which was purchased or repurchased from any Trust Fund pursuant
to any provision hereof. In the event that title to any such REO Property is
acquired, the deed or certificate of sale shall be issued to the Trustee, or to
its nominee, on behalf of the Certificateholders of the applicable Series. The
Master Servicer, on behalf of the applicable Trust Fund, shall either sell any
REO Property on or before December 31 of the third calendar year following the
calendar year in which such Trust Fund acquires ownership of such REO Property
for purposes of Section 860G(a)(8) of the Code or, at the expense of such Trust
Fund, request, more than 60 days before the day on which the three-year grace
period would otherwise expire, an extension of the three-year grace period,
unless the Master Servicer has delivered to the Trustee an Opinion of Counsel
addressed to the Trustee and the Master Servicer, to the effect that the
holding by such Trust Fund of such REO Property subsequent to such three year
period will not result in the imposition of taxes on "prohibited transactions"
thereof, as defined in Section 860F of the Code, or cause the Lower REMIC or
the Upper REMIC to fail to qualify as a REMIC under the REMIC Provisions or
comparable provisions of the laws of the any State at any time that any







                                     -60-
<PAGE>   66

Certificates are outstanding. The Master Servicer shall manage, conserve,
protect and operate each REO Property for the Certificateholders of the
applicable Series solely for the purpose of its prompt disposition and sale in
a manner which does not cause such REO Property to fail to qualify as
"foreclosure property" within the meaning of Section 860G(a)(8) or result in
the receipt by the Lower REMIC or the Upper REMIC of any "income from
non-permitted assets" within the meaning of Section 860F(a)(2)(B) of the Code
or any "net income from foreclosure property" which is subject to taxation
under the REMIC Provisions. Pursuant to its efforts to sell such REO Property,
the Master Servicer shall either itself or through an agent selected by the
Master Servicer protect and conserve such REO Property in the same manner and
to such extent as is customary in the locality where such REO Property is
located and in a manner consistent with Accepted Servicing Practices and may,
incident to its conservation and protection of the interests of the
Certificateholders of the applicable Series, rent the same, or any part
thereof, as the Master Servicer deems to be in the best interest of the
Certificateholders for the period prior to the sale of such REO Property.

         Any REO Disposition shall be for cash only (unless changes in the
REMIC Provisions made subsequent to the Startup Day allow a sale for other
consideration).

         The Master Servicer shall segregate and hold all funds collected and
received in connection with the operation of any REO Property separate and
apart from its own funds and general assets. The Master Servicer shall deposit,
or cause to be deposited, on a daily basis in the Custodial Account all
revenues received with respect to the REO Properties, net of any directly
related expenses incurred and funds withheld therefrom that are necessary for
the proper operation, management and maintenance of the REO Property.

         If as of the date of acquisition of title to any REO Property there
remain outstanding unreimbursed Servicing Advances with respect to such REO
Property or any outstanding Advances allocated thereto the Master Servicer,
upon an REO Disposition, shall be entitled to reimbursement for any related
unreimbursed Servicing Advances and any unreimbursed related Advances as well
as any unpaid Servicing Fees from proceeds received in connection with the REO
Disposition, as further provided in Section 3.15.

         The REO Disposition shall be carried out by the Master Servicer at
such price and upon such terms and conditions as the Master Servicer shall
determine; provided that, subject to the first paragraph of this Section, the
Master Servicer shall ensure that any action taken with respect to the sale of
an REO Property does not jeopardize the maximum benefits available under any
related Primary Mortgage Insurance Policy.

         The Master Servicer shall deposit the proceeds from the REO
Disposition, net of any payment to the Master Servicer as provided above, in
the Custodial Account upon receipt thereof for distribution in accordance with
Section 4.01; provided that any such net proceeds which are in excess of the
applicable outstanding principal balance plus all unpaid REO Imputed Interest
thereon through the last day of the month in which the REO Disposition occurred
and any related Servicing Advances which remain outstanding ("Excess Proceeds")
shall be deposited into the Excess Proceeds Account in accordance with the
provisions of Section 3.24(a).

         Notwithstanding the foregoing provisions of this Section 3.22, with
respect to any Mortgage Loan as to which the Master Servicer has received
notice of, or has actual knowledge of, the presence of any toxic or hazardous
substance on the Mortgaged Property, the Master Servicer shall not, on behalf
of the Trustee, either (i) obtain title to the related Mortgaged Property as a
result of or in lieu of foreclosure or otherwise, or (ii) otherwise acquire
possession of, the related Mortgaged Property, unless and until either (A) the
Master Servicer has, at least 30 days prior to taking such action, obtained and
delivered to the Seller and the Trustee an environmental audit report prepared
by a Person who regularly conducts environmental audits using customary
industry standards and (B) the Master Servicer deems that such action is in the
best economic interest of the applicable Trust Fund. In the event that the
Master Servicer determines not to foreclose or comparably convert any Mortgaged
Property pursuant to the immediately preceding sentence, then the Master
Servicer shall take such action as it deems to be in the best economic interest
of such Trust Fund (other than proceeding against the Mortgaged Property) and
is hereby authorized at such time as it deems appropriate to release such
Mortgaged Property from the lien of the related Mortgage.

         The cost of the environmental audit report contemplated by this
Section 3.22 shall be advanced by the Master Servicer as an expense of the
applicable Trust Fund, and the Master Servicer shall be reimbursed therefor
from the Custodial Account as provided in Section 3.11, any such right of
reimbursement being prior to the rights of the Certificateholders of the
applicable Series to receive any amount in the Custodial Account.

         If the Master Servicer determines, as described above, that it is in
the best economic interest of the applicable Trust Fund to take such actions as
are necessary to bring any such Mortgaged Property in compliance with
applicable environmental laws, or to take such action with respect to the
containment, clean-up or remediation of hazardous substances, hazardous
materials, hazardous wastes, or petroleum-based materials affecting any such
Mortgaged Property, then the Master Servicer shall take such action as it deems
to be in the best economic interest of the applicable Trust Fund. The cost of
any such compliance, containment, clean-up or remediation shall be advanced by
the Master Servicer as an expense of the applicable Trust Fund, and the Master
Servicer shall be entitled to be reimbursed therefor from the Custodial Account
as provided in Section 3.11, any such right of reimbursement being prior to the
rights of the Certificateholders of the applicable Series to receive any amount
in the Custodial Account.

         The Master Servicer shall have the option to purchase from the
applicable Trust Fund any Mortgage Loan that is 90 days or more delinquent
(i.e., any Mortgage Loan on which the related Mortgagor has failed to make four
or more consecutive Monthly Payments) and that the Master Servicer determines
in good faith will otherwise become subject to foreclosure proceedings (such
determination to be evidenced by an Officers' Certificate of the Master
Servicer delivered to the Trustee prior to purchase) for an amount equal to the
Purchase Price. The Purchase Price for any Mortgage Loan purchased pursuant to
this Section 3.22 shall be deposited in the Custodial Account, and upon receipt
of written certification from the Master Servicer of such deposit, the Trustee
shall release or cause to be released to the Master Servicer the related
Mortgage File and shall execute and deliver such instruments of transfer or
assignment, in each case without recourse, as the Master Servicer shall furnish
and as shall be necessary to vest in the Master Servicer title to any Mortgage
Loan released pursuant to this Section 3.22.

         3.23. Additional Obligations of the Master Servicer.

         On each Certificate Account Deposit Date, the Master Servicer shall
deliver to the Trustee for deposit in the Certificate Account from its own
funds and without any right of reimbursement therefor, a total amount equal to
the aggregate of the Prepayment Interest Shortfalls for such Distribution Date;
provided that the Master Servicer's obligations under this Section on any
Distribution Date shall not be more than the total amount of its servicing
compensation payable in such month.

         3.24. Excess Proceeds Account.

                  (a)      The Trustee shall establish and maintain one or more
                           accounts (collectively, the "Excess Proceeds
                           Account") in which the Master Servicer shall, on
                           behalf of each Trust Fund, deposit or cause to be
                           deposited on a daily basis, or as and when received
                           from the Sub-Servicers, the Excess Proceeds, if any,
                           with respect to each Mortgage Loan as to which an
                           REO Disposition occurs. The Excess Proceeds Account
                           shall be maintained as a segregated account,
                           separate and apart from trust funds created for
                           mortgage pass-through certificates of other series,
                           from funds of investors, from funds or other assets
                           of the Trustee, and from the other accounts of the
                           Trustee.

                  (b)      On or before 2:00 P.M. (Pacific Standard Time) on
                           each Certificate Account Deposit Date, the Trustee
                           shall withdraw or cause to be withdrawn the entire
                           amount on deposit in the Excess Proceeds Account and
                           shall deposit or cause to be deposited such amount
                           in the Certificate Account, by wire transfer of
                           immediately available funds.

                  (c)      [RESERVED]

                  (d)      The Excess Proceeds Account shall be an Eligible
                           Account in accordance with the definition of "Excess
                           Proceeds Account" in Section 1.01. The Trustee
                           shall, upon written request from the Master
                           Servicer, invest or cause the institution
                           maintaining the Excess Proceeds Account to invest
                           the funds in the Excess Proceeds Account in one or
                           more Permitted Instruments designated in the name of
                           the Trustee for the benefit of the
                           Certificateholders, each of which Permitted
                           Instruments shall be held to maturity, unless
                           payable on demand, and shall mature, unless payable
                           on demand, not later than the Business Day
                           immediately preceding the Certificate Account
                           Deposit Date next following the date of such
                           investment (except that if such Permitted Instrument
                           is an obligation of the institution with which the
                           Excess

                           Proceeds Account is maintained, then such Permitted
                           Instrument shall mature not later than such
                           Certificate Account Deposit Date). All income and
                           gain realized from any such investment as well as
                           any interest earned on deposits in the Excess
                           Proceeds Account shall be for the benefit of the
                           Certificateholders and shall be held in the Excess
                           Proceeds Account (or in Permitted Instruments in
                           which the funds in the Excess Proceeds Account are
                           invested) until transferred from the Excess Proceeds
                           Account to the Certificate Account in accordance
                           with Section 3.24(b) or (c). The amount of any loss
                           incurred in respect of any such investment shall be
                           borne by the Certificateholders without any right of
                           reimbursement.

                  (e)      As part of each Determination Date Report delivered
                           to the Trustee in accordance with Section 4.03(a),
                           the Master Servicer shall provide information with
                           respect to the amount, if any, of Excess Proceeds
                           deposited in the Excess Proceeds Account in respect
                           of each Mortgage Loan as to which an REO Disposition
                           occurred during the related Prepayment Period.

                  (f)      The Trustee shall promptly provide notice to the
                           Seller and the Master Servicer of the initial
                           location of the Excess Proceeds Account and shall
                           promptly provide notice to the Seller and the Master
                           Servicer of the location of the Excess Proceeds
                           Account after any change in location of the Excess
                           Proceeds Account.

         3.25. Maintenance of the Primary Mortgage Insurance Policies;
Collections Thereunder.

         The Master Servicer shall not take any action which would result in
non-coverage under any applicable Primary Mortgage Insurance Policy of any loss
which, but for the actions of the Master Servicer, would have been covered
thereunder. The Master Servicer shall use reasonable efforts to keep in force
and effect each such Primary Mortgage Insurance Policy applicable to a Mortgage
Loan for so long as the related Mortgagor is obligated to maintain such Primary
Mortgage Insurance Policy under the terms of the related Mortgage Loan or until
the Loan-to-Value Ratio of the related Mortgage Loan has been reduced to less
than 80%, whichever is earlier. The Master Servicer shall not cancel or refuse
to renew any such Primary Mortgage Insurance Policy applicable to a Mortgage
Loan that is in effect at the Closing Date and is required to be kept in force
hereunder unless a replacement Primary Mortgage Insurance Policy for such
canceled or non-renewed policy is obtained from and maintained with a Qualified
Mortgage Insurer. In connection with any assumption or modification agreement
entered into or to be entered into pursuant to Section 3.14, the Master
Servicer shall promptly notify the insurer under the related Primary Mortgage
Insurance Policy, if any, of such assumption or modification in accordance with
the terms of such policy and shall take all actions which may be required by
such insurer as a condition to the continuation of coverage under the Primary
Mortgage Insurance Policy. If such Primary Mortgage Insurance Policy is
terminated as a result of such assumption or substitution of liability, the
Loan Seller shall obtain a replacement Primary Mortgage Insurance Policy as
provided above. Any amounts advanced by the Master Servicer to maintain Primary
Mortgage Insurance shall be recoverable by the Master Servicer pursuant to
Section 3.11 out of Liquidation Proceeds, Insurance Proceeds or otherwise.







                                     -64-
<PAGE>   70

         The Master Servicer shall present, on behalf of the Trustee and
Certificateholders, claims to the insurer under any Primary Mortgage Insurance
Policies and, in this regard, take such reasonable action as shall be necessary
to permit recovery under any Primary Mortgage Insurance Policies respecting
defaulted Mortgage Loans. Pursuant to Section 3.10, any amounts collected by
the Master Servicer under any Primary Mortgage Insurance Policies shall be
deposited in the Custodial Account, subject to withdrawal pursuant to Section
3.11.

         3.26. Special Servicing.

         The Master Servicer may, in its sole and absolute discretion, enter
into a Special Servicing Agreement with an unaffiliated holder of 100%
Percentage Interest of a Class B Security to be substantially in the form of
Exhibit H hereto, or subject to each Rating Agency's acknowledgment that the
ratings of the Securities in effect immediately prior to the entering into of
such agreement would not be qualified, downgraded or withdrawn and the
Securities would not be placed on credit review status (except for possible
upgrading) as a result of such agreement. Any such agreement may contain
provisions whereby such holder may instruct the Master Servicer to commence or
delay foreclosure proceedings with respect to delinquent Mortgage Loans and
will contain provisions for the disposition of cash by the holder that would be
available for distribution to Certificateholders if Liquidation Proceeds are
less than they otherwise may have been had the Master Servicer acted in
accordance with its normal procedures.

         3.27. Duties with respect to REMICs.

                  (a)      [RESERVED]

                  (b)      The Master Servicer shall assist the Trustee in
                           taking, to the extent reasonably requested to do so,
                           such action as shall be necessary to create or
                           maintain the status of the Upper REMIC and the Lower
                           REMIC as REMICs under the REMIC Provisions.

                  (c)      For the purposes of this Paragraph (c), "Adverse
                           REMIC Event" shall mean any action or failure to act
                           which could (i) endanger the status of either the
                           Upper REMIC or the Lower REMIC as a REMIC or (ii)
                           result in the imposition of a tax upon any Trust
                           Fund (including but not limited to the tax on
                           prohibited transactions as defined in Section
                           860F(a)(2) of the Code and the tax on contributions
                           to a REMIC set forth in Section 860G(d) of the
                           Code). Prior to taking any action with respect to
                           any Trust Fund or its assets, or causing either the
                           Upper REMIC or the Lower REMIC to take any action
                           which is not expressly permitted under the terms of
                           this Agreement or the Series Supplement, the Master
                           Servicer will consult with the Trustee or its
                           designee, in writing, with respect to whether such
                           action could cause an Adverse REMIC Event to occur
                           with respect to either the Upper REMIC or the Lower
                           REMIC , and the Master Servicer shall not take any
                           such action or cause either the Upper REMIC or the
                           Lower REMIC to take any such action as to which the
                           Trustee has advised

                           occur. The Trustee may consult with counsel to make
                           such written advice, and the cost of same shall be
                           borne by the party seeking to take the action not
                           permitted by this Agreement (but in no event shall
                           such cost be an expense of the Trustee).

                  (d)      The Master Servicer shall, for federal income tax
                           purposes, maintain books and records with respect to
                           any Trust Fund on a calendar year and on an accrual

                           Counsel (which such Opinion of Counsel shall not be
                           an expense of the Trustee) to the effect that the
                           inclusion of such assets in either the Upper REMIC
                           or the Lower REMIC will not cause either the Upper
                           REMIC or the Lower REMIC to fail to qualify as a
                           REMIC at any time that any Certificates are
                           outstanding or subject either the Upper REMIC or the
                           Lower REMIC to any tax under the REMIC Provisions or
                           other applicable provisions of federal, state and
                           local law or ordinances.

                  (f)      The Master Servicer shall not enter into any
                           arrangement by which either the Upper REMIC or the
                           Lower REMIC will receive a fee or other compensation
                           for services nor permit either of such REMICs to
                           receive any income from assets other than "qualified
                           mortgages" as defined in Section 860G(a)(3) of the
                           Code or "permitted investments" as defined in
                           Section 860G(a)(5) of the Code.

                  (g)      The Master Servicer agrees to indemnify any Trust
                           Fund, the Seller, the Loan Seller and the Trustee
                           for any taxes and costs (including, without
                           limitation, any reasonable attorneys' fees) imposed
                           on or incurred by any Trust Fund, the Seller or the
                           Trustee, as a result of a breach of the Master
                           Servicer's covenants set forth in this Section 3.27
                           or in Article III with respect to compliance with
                           the REMIC Provisions, including without limitation,
                           any penalties arising from the Trustee's execution
                           of Tax Returns prepared by the Master Servicer that
                           contain errors or omissions.

                                    (i)      the Trustee expects that the final

                                             Certificates at the office of the
                                             Trustee therein specified, and

                                    (ii)     no interest shall accrue on such
                                             Certificates from and after the

         Any funds not distributed to any Holder or Holders of Certificates of
such Series on such Distribution Date because of the failure of such Holder or
Holders to tender their Certificates shall, on such date, be set aside and held
in trust uninvested and credited to the account of the appropriate
non-tendering Holder or Holders. If any Certificates as to which notice has
been given pursuant to this Section 4.01(f) shall not have been surrendered for
cancellation within six months after the time specified in such notice, the
Trustee shall mail a second notice to the remaining non-tendering

If within nine months after the second notice any such Certificates shall not
have been surrendered for cancellation, the Seller shall be entitled to all
unclaimed funds and other assets which remain subject hereto. No interest shall
accrue or be payable to any Certificateholder on any amount held in trust as a
result of such Certificateholder's failure to surrender its Certificate(s) for
final payment thereof in accordance with this Section 4.01(f).

         4.02. Statements to Certificateholders.

                                             obligation shall be deemed to have
                                             been satisfied to the extent that
                                             substantially comparable
                                             information shall be provided by

                           Trustee for purposes of making the calculations
                           referred to in the following paragraph, as set forth
                           in Exhibit G hereto and the information necessary to
                           enable the Trustee to prepare the statements
                           referred to in Section 6 of the Series Supplement
                           and in Section 4.02 of this Agreement. Not later

                           Business Day preceding each Certificate Account
                           Deposit Date, the Trustee shall furnish by telecopy
                           to the Master Servicer a statement (the information
                           in such statement to be made available to
                           Certificateholders or the Seller by the Master
                           Servicer on request) setting forth (i) the Available
                           Distribution Amount (in the aggregate and on a
                           Series-by-Series basis) and (ii) the amounts
                           required to be withdrawn from the Custodial Account
                           and deposited into the Certificate Account on the
                           immediately succeeding Certificate Account Deposit

                           have no obligation to recompute, recalculate or
                           verify any information provided to it by the Master
                           Servicer. The determination by the Trustee of such
                           amounts shall, in the absence of

                           obvious error, be presumptively deemed to be correct
                           for all purposes hereunder.

                  (b)      Prior to the close of business on the Business Day
                           preceding each Certificate Account Deposit Date, the
                           Trustee shall notify the Master Servicer of the
                           amount of Advances (other than Servicing Advances)
                           required to be made for the related Distribution
                           Date, which shall be in an aggregate amount equal to
                           the aggregate amount of Monthly Payments, (with each
                           interest portion thereof adjusted to the Net
                           Mortgage Rate) less the amount of any related Debt
                           Service Reductions or reductions in the amount of
                           interest collectable from the Mortgagor pursuant to
                           the Soldiers' and Sailors' Civil Relief Act of 1940,
                           on the Outstanding Mortgage Loans as of the related
                           Due Date, which Monthly Payments were delinquent as
                           of the close of business as of the related
                           Determination Date; no Advance shall be made if it
                           would be a Nonrecoverable Advance. On or before
                           12:00 P.M. (Pacific Standard Time) on each
                           Certificate Account Deposit Date, the Master
                           Servicer shall either (i) deposit in the Certificate
                           Account from its own funds, or funds received
                           therefor from the SubServicers, an amount equal to
                           the Advances to be made by the Master Servicer in
                           respect of the related Distribution Date, (ii)
                           withdraw from amounts on deposit in the Custodial
                           Account and deposit in the Certificate Account all
                           or a portion of the amounts held for future
                           distribution in discharge of any such Advance, or
                           (iii) make advances in the form of any combination
                           of (i) and (ii) aggregating the amount of such
                           Advance. Any portion of the amounts held for future
                           distribution so used shall be replaced by the Master
                           Servicer by deposit in the Certificate Account on or
                           before 11:00 A.M. (Pacific Standard Time) on any
                           future Certificate Account Deposit Date to the
                           extent that funds attributable to the Mortgage Loans
                           that are available in the Custodial Account for
                           deposit in the Certificate Account on such
                           Certificate Account Deposit Date shall be less than
                           payments to Certificateholders required to be made
                           on the following Distribution Date. The amount of
                           any reimbursement in respect of outstanding Advances
                           on any Distribution Date shall be allocated to
                           specific Monthly Payments due but delinquent for
                           previous Due Periods, which allocation shall be
                           made, to the extent practicable, to Monthly Payments
                           which have been delinquent for the longest period of
                           time. Such allocations shall be conclusive for
                           purposes of reimbursement to the Master Servicer
                           from recoveries on related Mortgage Loans pursuant
                           to Section 3.11. The determination by the Master
                           Servicer that it has made a Nonrecoverable Advance
                           or that any proposed Advance, if made, would
                           constitute a Nonrecoverable Advance, shall be
                           evidenced by a certificate of a Servicing Officer
                           delivered to the Loan Seller and the Trustee. The
                           Trustee shall deposit all funds it receives pursuant
                           to this Section 4.03 into the Certificate Account.

                           amount determined by the Trustee pursuant to

                           Time), on the Certificate Account Deposit Date,
                           unless by such time the Master Servicer shall have

                           Master Servicer under this Agreement in accordance

Certificateholders of interest or original issue discount on the Mortgage
Loans, that the Trustee reasonably believes are applicable under the Code. The
consent of Certificateholders shall not be required for such withholding. In
the event the Trustee withholds any amount from interest or original issue
discount payments or advances thereof to any Certificateholder pursuant to
federal withholding requirements, the Trustee shall, together with its monthly
report to such Certificateholders pursuant to Section 4.02 hereof, indicate
such amount withheld.

         4.06. Reporting of Realized Losses.

         Prior to each Distribution Date, the Master Servicer shall determine
the total amount of Realized Losses (in the aggregate and on a Loan Group by
Loan Group basis), if any, that resulted from any Cash Liquidation, Debt
Service Reduction, Deficient Valuation or REO Disposition that occurred during
the related Prepayment Period. The amount of each Realized Loss shall be
evidenced by an Officer's Certificate by the Master Servicer delivered to the
Trustee.

V                               THE CERTIFICATES

         5.01. The Certificates.

         The Certificates shall be substantially in the form set forth in
Exhibit A and shall be executed and delivered by the Seller to the Trustee for
authentication and redelivery to or upon the order of the Seller upon receipt
by the Trustee of the documents specified in Section 2.01. The Certificates
shall be issued in denominations of 100/100th Fractional Undivided Interest and
shall be executed by manual or facsimile signature on behalf of the Seller by
its President or one of its Vice Presidents, or one of its Authorized Officers
(as appointed pursuant to the Bylaws of the Seller), under its seal imprinted
thereon and attested by the manual or facsimile signature of its Secretary or
one of its Assistant Secretaries. Certificates bearing the manual or facsimile
signature of individuals who were at any time the proper officers of the Seller
shall bind the Seller, notwithstanding that such individuals or any of them
have ceased to hold such offices prior to the authentication and delivery of
such Certificates or did not hold such offices at the date of such Certificate.
No Certificate shall be entitled to any benefit under this Agreement, or be
valid for any purpose, unless there appears on such Certificate a certificate
of authentication substantially in the form set forth in Exhibit A executed by
the Trustee by manual signature of an authorized signatory, and such
certificate upon any Certificate shall be conclusive evidence, and the only
evidence, that such Certificate has been duly authenticated and delivered
hereunder. The Trustee's signature shall be for authentication purposes and
neither the Trustee nor any Person signing on its behalf shall have any
liability on the respective Certificate (other than the certificate of
authentication thereon). All Certificates shall be dated the date of their
authentication.

         5.02. Registration of Transfer and Exchange of Certificates.

         The Trustee, or such other Person as it shall designate in writing,
shall be the Certificate Registrar, who shall cause to be kept at the office or
agency to be maintained by the Certificate Registrar a Certificate Register in
which, subject to such reasonable regulations as it may prescribe, the
Certificate Registrar shall provide for the registration of each Series of
Certificates and of transfers and exchanges of all such Certificates as herein
provided. The Trustee, whose principal corporate trust office is located at the
Corporate Trust Office, is hereby initially appointed Certificate Registrar for
the purpose of registering each Series of Certificates and transfers and
exchanges of all such Certificates as herein provided.

         No transfer of a Certificate or Certificates shall be made unless such
transfer is made pursuant to an effective registration statement under the
Certificates Act of 1933, as amended, (the "Act") or is exempt from the
registration requirements under the Act. In the event that a transfer is 







                                     -74-
<PAGE>   80

to be made in reliance upon an exemption from the Act, the Certificate
Registrar may require, in order to assure compliance with the Act, that the
Certificateholder desiring to effect such transfer and such Certificateholder's
prospective transferee each certify to the Certificate Registrar in writing the
facts surrounding such transfer. In the event that such certification of facts
does not on its face establish the availability of an exemption under Section
4(5) or a comparable provision of the Act, the Certificate Registrar may
require an Opinion of Counsel satisfactory to it that such transfer may be made
pursuant to an exemption from the Act, which Opinion of Counsel shall not be an
expense of the Master Servicer or the Trustee. Neither the Master Servicer nor
the Trustee is obligated to register any of the Certificates under the Act or
any other federal or state securities law.

         It is a condition to the transfer of any Certificate that the
transferee certify in writing to the Seller and the Certificate Registrar that
such transferee (i) is not an employee benefit plan, trust or account,
including an individual retirement account, that is subject to the Employee
Retirement Income Security Act of 1974, as amended, or that is described in
Section 4975(e)(1) of the Federal Tax Laws (any such plan, trust or account
being referred to as a "Plan") and (ii) has not acquired and will not acquire
such Certificate with plan assets, within the meaning of 29 CFR 2510.3-101, of
a Plan.

         A form of the letter from the purchaser of any Certificate, containing
the representations described in the preceding two paragraphs, is in the form
of a Purchaser Letter attached hereto as Exhibit E.

         Subject to the preceding three paragraphs, upon surrender for
registration of transfer of any Certificate at any office or agency of the
Certificate Registrar maintained for such purpose pursuant to this Section 5.02
and upon satisfaction of all requirements for transfer, the Seller shall
execute, and the Trustee shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Certificates of the same
Series and of a like aggregate Fractional Undivided Interest.

         At the option of the Certificateholders, Certificates may, upon
satisfaction of the requirement for exchange, be exchanged for other
Certificates of such Series of authorized denominations of the same aggregate
Fractional Undivided Interest, upon surrender of the Certificates to be
exchanged at any such office or agency. Whenever any Certificates are so
surrendered for exchange the Seller shall execute, and the Trustee shall
authenticate and deliver, the Certificates which the Certificateholder making
the exchange is entitled to receive. Every Certificate presented or surrendered
for transfer or exchange shall (if so required by the Seller or the Trustee or
the Certificate Registrar) (a) be duly endorsed by, or be accompanied by a
written instrument of transfer in form acceptable to transfer agents registered
with the Securities and Exchange Commission and the Seller, the Trustee and the
Certificate Registrar, and (b) be duly executed by the holder thereof or his
attorney duly authorized in writing.

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




                                     -75-
<PAGE>   81

         All Certificates surrendered for transfer and exchange shall be held
by the Certificate Registrar for a period of three years after termination of
this Agreement, and thereafter may be destroyed, in which event a destruction
certificate shall be delivered to the Trustee.

         5.03. Mutilated, Destroyed, Lost or Stolen Certificates.

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

         5.04. Persons Deemed Owners.

         Prior to due presentation of a Certificate for registration or
transfer, the Seller, the Trustee, the Certificate Registrar and any agent of
the Seller, the Trustee or the Certificate Registrar may treat the person in
whose name any Certificate is registered as the owner of such Certificate for
the purpose of receiving distributions pursuant to Section 4.01(b) and for all
other purposes whatsoever, and neither the Seller, the Trustee, the Certificate
Registrar nor any agent of the Seller, the Trustee or the Certificate Registrar
shall be affected by notice to the contrary.

 
VI                                 LIABILITY

         6.01. Liability of the Seller, the Loan Seller and the Master
         Servicer.

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

         6.02. Merger; Consolidation or Conversion of the Seller or the Master
         Servicer.

         Except in connection with a merger or consolidation permitted by this
Section 6.02, the Seller, the Loan Seller and the Master Servicer (except as
contemplated in the announcement dated June 23, 1997 regarding the acquisition
of the Master Servicer by Dime Bancorp, Inc by means of a stock for stock
exchange) each will keep in full effect its existence, rights and franchises as
a 







                                     -76-
<PAGE>   82

corporation under the laws of the state of its incorporation, and each will
obtain and preserve its qualification to do business as a foreign corporation
in each jurisdiction in which such qualification is or shall be necessary to
protect the validity and enforceability of this Agreement, the Certificates or
any of the Mortgage Loans and to perform its respective duties under this
Agreement.

         Any Person into which the Seller, the Loan Seller or the Master
Servicer may be merged, consolidated or converted, or any corporation resulting
from any merger or consolidation to which the Seller, the Loan Seller or the
Master Servicer shall be a party, or any Person succeeding to the business of
the Seller, the Loan Seller or the Master Servicer shall be the successor of
the Seller, the Loan Seller or the Master Servicer hereunder, without the
execution or filing of any paper or any further act on the part of any of the
parties hereto, anything herein to the contrary notwithstanding.

         Any Person into which the Seller, Loan Seller or Master Servicer may
be merged, consolidated or converted, or any corporation resulting from any
merger or consolidation to which the Seller, Loan Seller or Master Servicer
shall be a party, as the case may be, or any Person succeeding to the business
of the Seller, Loan Seller or Master Servicer (including by a transfer of
servicing portfolio or operations by the Loan Seller or Master Servicer), shall
be the successor of the Seller, Loan Seller or Master Servicer hereunder, as
the case may be, without the execution or filing of any paper or any further
act on the part of any of the parties hereto, anything herein to the contrary
notwithstanding; provided, however, that the successor or surviving Person to
the Loan Seller or Master Servicer must meet the criteria set forth in Section
7.02 for a successor Master Servicer and shall be qualified to sell mortgage
loans to and service mortgage loans for FNMA or FHLMC.

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

         Neither the Seller, the Master Servicer nor any of the directors,
officers, employees or agents of the Seller or the Master Servicer shall be
under any liability to any Trust Fund or the related Certificateholders for any
action taken or for refraining from the taking of any action in good faith
pursuant to this Agreement, or for errors in judgment; provided, however, that
this provision shall not protect the Seller or the Master Servicer (but this
provision shall protect the above described persons) against any breach of
warranties or representations made herein, or against any specific liability
imposed on the Master Servicer pursuant to Section 3.01 or any other Section
hereof; and provided further that this provision shall not protect the Seller,
the Master Servicer or any such person, against any liability which would
otherwise be imposed by reason of willful misfeasance, bad faith or gross
negligence in the performance of duties or by reason of reckless disregard of
obligations and duties hereunder. The Seller, the Master Servicer and any
director, officer, employee or agent of the Seller or the Master Servicer may
rely in good faith on any document of any kind prima facie properly executed
and submitted by any Person respecting any matters arising hereunder. The
Seller, the Master Servicer and any director, officer, employee or agent of the
Seller or the Master Servicer shall be indemnified and held harmless by any
Trust Fund against any loss, liability or expense 








                                     -77-
<PAGE>   83

incurred in connection with any legal action relating to this Agreement or the
Certificates INCLUDING ANY LOSS, LIABILITY OR EXPENSE CAUSED BY ANY INDEMNIFIED
PARTY'S OWN NEGLIGENCE, other than any loss, liability or expense related to
Master Servicer's servicing obligations with respect to any specific mortgage
loan or mortgage loans (except as any such loss, liability or expense shall be
otherwise reimbursable pursuant to this Agreement) or related to the Master
Servicer's obligations under Section 3.01, or any loss, liability or expense
incurred by reason of willful misfeasance, bad faith or gross negligence in the
performance of duties hereunder or by reason of reckless disregard of
obligations and duties hereunder. Neither the Seller nor the Master Servicer
shall be under any obligation to appear in, prosecute or defend any legal
action which is not incidental to its respective duties under this Agreement
and which in its opinion may involve it in any expense or liability; provided,
however, that the Seller or the Master Servicer may in its sole discretion
undertake any such action which it may deem necessary or desirable with respect
to this Agreement and the rights and duties of the parties hereto and the
interests of the Certificateholders hereunder. In such event, the legal
expenses and costs of such action and any liability resulting therefrom (except
any action or liability related to the Master Servicer's obligations under
Section 3.01) shall be expenses, costs and liabilities of the applicable Trust
Fund, and the Seller and the Master Servicer shall be entitled to be reimbursed
therefor from the Certificate Account as provided in Section 3.11, any such
right of reimbursement being prior to the rights of Certificateholders to
receive any amount in the Certificate Account.

         6.04. Limitation on Resignation of the Master Servicer.

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


VII                         MASTER SERVICER DEFAULT

         7.01. Events of Default.

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

         (i) any failure by the Master Servicer to remit to the Trustee for
distribution to the Certificateholders any payment (other than an Advance)
required to be made under the terms of the Certificates of a Series or this
Agreement which continues unremedied for a period of five days after the date
upon which written notice of such failure, requiring the same to be remedied,
shall have been given to the Master Servicer by the Seller or the Loan Seller
(with a copy to the Trustee) or the Trustee, or to the Master Servicer, the
Seller and the Trustee by the Holders of Certificates of such Series evidencing
Fractional Undivided Interests aggregating not less than 25% of the applicable
Trust Fund; or

         (ii) any failure on the part of the Master Servicer duly to observe or
perform in any material respect any other of the covenants or agreements on the
part of the Master Servicer contained in the Certificates or in this Agreement
(including any breach of the Master Servicer's representations and warranties
pursuant to Section 2.03(a) which materially and adversely affects



                                     -78-
<PAGE>   84

the interests of the Certificateholders of a Series) which continues unremedied
for a period of 30 days after the date on which written notice of such failure,
requiring the same to be remedied, shall have been given to the Master Servicer
by the Seller or the Loan Seller (with a copy to the Trustee) or the Trustee,
or to the Master Servicer, the Seller and the Trustee by the Holders of
Certificates of the affected Series evidencing Fractional Undivided Interests
aggregating not less than 25% of the Trust Fund for the affected Series; or

         (iii) a decree or order of a court or agency or supervisory authority
having jurisdiction in an involuntary case under any present or future federal
or state bankruptcy, insolvency or similar law or the appointment of a
conservator or receiver or liquidator in any insolvency, readjustment of debt,
marshalling of assets and liabilities or similar proceedings, or for the
winding-up or liquidation of its affairs, shall have been entered against the
Master Servicer and such decree or order shall have remained in force
undischarged or unstayed for a period of 60 consecutive days; or

         (iv) the Master Servicer shall consent to the appointment of a
conservator or receiver or liquidator in any insolvency, readjustment of debt,
marshalling of assets and liabilities or similar proceedings of or relating to
the Master Servicer or of or relating to all or substantially all of its
property; or

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

         (vi) the Master Servicer shall notify the Trustee pursuant to Section
4.03(b) and shall fail to deposit in the Certificate Account on any Certificate
Account Deposit Date by the time required therein an amount equal to any
required Advance in accordance with the procedures set forth in Section
4.03(b).

         If an Event of Default described in clauses (i) - (v) of this Section
shall occur with respect to a Series (each event described in clauses (iii) -
(v) of this Section to be deemed to occur with respect to each Series if such
event occurs), then, and in each and every such case, so long as such Event of
Default shall not have been remedied, the Seller or the Trustee may, and at the
direction of the Holders of Certificates of such Series evidencing Fractional
Undivided Interests aggregating not less than 51%, the Trustee shall, by notice
to the Master Servicer (and to the Seller and the Loan Seller if given by the
Trustee or to the Trustee and the Loan Seller if given by the Seller terminate
all of the rights and obligations of the Master Servicer (but not as Loan
Seller in the event they are the same Person) under this Agreement and in and
to the applicable Trust Fund, other than its rights as a Certificateholder
hereunder. If an Event of Default described in clause (vi) hereof shall occur,
the Trustee shall, by notice to the Master Servicer, the Seller and the Loan
Seller, terminate all of the rights and obligations of the Master Servicer
under this Agreement and in and to the applicable Trust Fund, other than its
rights as a Certificateholder hereunder. On or after the receipt by the Master
Servicer of such notice, all authority and power of the Master Servicer under
this Agreement, whether with respect to the Certificates (other than as a
holder thereof) or the Mortgage Loans or otherwise, shall pass to and be vested
in the Trustee pursuant to and under this Section, and, without limitation, the
Trustee is hereby authorized and empowered to execute and deliver, on behalf of
the


                                     -79-
<PAGE>   85



Master Servicer, as attorney-in-fact or otherwise, any and all documents and
other instruments, and to do or accomplish all other acts or things necessary
or appropriate to effect the purposes of such notice of termination, whether to
complete the transfer and endorsement or assignment of the Mortgage Loans and
related documents, or otherwise. The Master Servicer agrees to cooperate with
the Trustee in effecting the termination of the Master Servicer's
responsibilities and rights hereunder, including, without limitation, the
transfer to the Trustee or its appointed agent for administration by it of all
cash amounts which shall at the time be deposited by the Master Servicer or
should have been deposited to the Custodial Account, the Excess Proceeds
Account or the Certificate Account or thereafter be received with respect to
the Mortgage Loans. The Trustee shall not be deemed to have breached any
obligation hereunder as a result of a failure to make or delay in making any
distribution as and when required hereunder caused by the failure of the Master
Servicer to remit any amounts received on it or to deliver any documents held
by it with respect to the Mortgage Loans. For purposes of this Section 7.01,
the Trustee shall not be deemed to have knowledge of an Event of Default unless
a Responsible Officer of the Trustee assigned to and working in the Trustee's
Corporate Trust Office has actual knowledge thereof or unless notice of any
event which is in fact such an Event of Default is received by the Trustee and
such notice references the Certificates, the applicable Trust Fund or this
Agreement.

         Notwithstanding any termination of the activities of North American
Mortgage Company ("NAMC") in its capacity as Master Servicer hereunder, NAMC
shall be entitled to receive, out of any Late Collection of a Monthly Payment
on a Mortgage Loan which was due prior to the notice terminating NAMC's rights
and obligations as Master Servicer hereunder and received after such notice,
that portion to which NAMC would have been entitled pursuant to Sections
3.11(ii), (iii), (iv), (v) and (viii) as well as its Servicing Fee in respect
thereof, and any other amounts payable to NAMC hereunder the entitlement to
which arose prior to the termination of its activities hereunder.

         7.02. Trustee to Act; Appointment of Successor.

         On and after the time the Master Servicer receives a notice of
termination pursuant to Section 7.01, the Trustee or its appointed agent shall
be the successor in all respects to the Master Servicer in its capacity as
Master Servicer under this Agreement and the transactions set forth or provided
for herein and shall be subject thereafter to all the responsibilities, duties
and liabilities relating thereto placed on the Master Servicer including the
obligation to make Advances which have been or will be required to be made
(except for the responsibilities, duties and liabilities contained in Section
2.03 and its obligations to deposit amounts in respect of losses pursuant to
Sections 3.12 and 4.01(e)) by the terms and provisions hereof; and provided
further, that any failure to perform such duties or responsibilities caused by
the Master Servicer's failure to provide information required by Section 4.03
shall not be considered a default by the Trustee hereunder. As compensation
therefor, the Trustee shall be entitled to all funds relating to the Mortgage
Loans which the Master Servicer would have been entitled to charge to the
Custodial Account and the Certificate Account if the Master Servicer had
continued to act hereunder. Notwithstanding the above, the Trustee may, if it
shall be unwilling to so act, or shall, if it is unable to so act (exclusive of
the obligations set forth in Section 4.03) or if the Holders of Certificates of
a Series evidencing Fractional Undivided Interests aggregating not less than
51% of the Trust Fund for a Series so request in writing to the Trustee,
appoint, or petition a court of competent jurisdiction to appoint, any mortgage
loan servicing institution (acceptable to the Rating Agencies) having a net
worth of not


                                     -80-
<PAGE>   86


less than $10,000,000 (or other amount acceptable to the Rating Agencies) as
the successor to the Master Servicer hereunder in the assumption of all or any
part of the responsibilities, duties or liabilities of the Master Servicer
hereunder. Pending appointment of a successor to the Master Servicer hereunder,
the Trustee shall act in such capacity as hereinabove provided. In connection
with such appointment and assumption, the Trustee may make such arrangements
for the compensation of such successor out of payments on Mortgage Loans as it
and such successor shall agree; provided, however, that no such compensation
shall be in excess of that permitted the Master Servicer hereunder. The Loan
Seller, the Seller, the Trustee and such successor shall take such action,
consistent with this Agreement, as shall be necessary to effectuate any such
succession.

         Any successor, including the Trustee, to the Master Servicer shall
maintain in force during its term as master servicer hereunder policies and
fidelity bonds to the same extent as the Master Servicer is so required
pursuant to Section 3.18.

         7.03. Notification to Certificateholders.

                  (a)      Upon any such termination or appointment of a
                           successor to the Master Servicer, the Trustee shall
                           give prompt notice thereof to Certificateholders.

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

         7.04. Waiver of Events of Default.

         The Holders of Certificates of each Series evidencing Fractional
Undivided Interests aggregating not less than 662/3% affected by a default or
Event of Default hereunder, may waive such default or Event of Default;
provided, however, that (a) a default or Event of Default under clause (i) of
Section 7.01 may be waived only by all of the Holders of Certificates affected
by such default or Event of Default and (b) no waiver pursuant to this Section
7.04 shall affect the Holders of Certificates in the manner set forth in the
third paragraph of Section 11.01 or have a material adverse affect on any
non-consenting Certificateholder. Upon any such waiver of a default or Event of
Default as provided above, such default or Event of Default shall cease to
exist and shall be deemed to have been remedied for every purpose hereunder. No
such waiver shall extend to any subsequent or other default or Event of Default
or impair any right consequent thereon except to the extent expressly so
waived.


VIII                         CONCERNING THE TRUSTEE

         8.01. Duties of Trustee.

         The Trustee, prior to the occurrence of an Event of Default and after
the curing or waiver of all Events of Default which may have occurred,
undertakes to perform such duties and only such



                                     -81-
<PAGE>   87


duties as are specifically set forth in this Agreement. If an Event of Default
occurs and is continuing, the Trustee shall exercise such of the rights and
powers vested in it by this Agreement, and use the same degree of care and
skill in their exercise as a prudent man would exercise or use under the
circumstances in the conduct of his own affairs unless it is acting as Master
Servicer, in which case it shall use the degree of care and skill as is
required of the Master Servicer under this Agreement. Any permissive right of
the Trustee enumerated in this Agreement shall not be construed as a duty.

         The Trustee, upon receipt of all resolutions, certificates,
statements, opinions, reports, documents, orders or other instruments furnished
to the Trustee which are specifically required to be furnished pursuant to any
provision of this Agreement, shall examine them to determine whether they
conform to the requirements of this Agreement. If any such instrument is found
not to conform to the requirements of this Agreement in a material manner, the
Trustee shall request that the presenting Person have the instrument corrected.

         The Trustee shall sign on behalf of each Trust Fund any tax return
that the Trustee is required to sign pursuant to applicable federal, state or
local tax laws.

         The Trustee covenants and agrees that it shall perform its obligations
hereunder in a manner so as to maintain the status of either the Lower REMIC or
the Upper REMIC as a REMIC under the REMIC Provisions and to prevent the
imposition of any federal, state or local income, prohibited transaction,
contribution or other tax on any Trust Fund to the extent that maintaining such
status and avoiding such taxes are reasonably within the control of the Trustee
and are reasonably within the scope of its duties under this Agreement.

         The Trustee shall cooperate to the extent practicable, with the Seller
in the preparation of any information, for the Holder of any Certificate, which
the Seller in its sole discretion deems necessary and appropriate for purposes
of satisfying applicable information reporting requirements under Rule 144A or
otherwise.

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

         (i) Prior to the occurrence of an Event of Default, and after the
curing or waiver of all such Events of Default which may have occurred, the
duties and obligations of the Trustee shall be determined solely by the express
provisions of this Agreement, the Trustee shall not be liable except for the
performance of such duties and obligations as are specifically set forth in
this Agreement, no implied covenants or obligations shall be read into this
Agreement against the Trustee and, in the absence of bad faith on the part of
the Trustee, the Trustee may conclusively rely, as to the truth of the
statements and the correctness of the opinions expressed therein, upon any
certificates or opinions furnished to the Trustee and conforming to the
requirements of this Agreement;

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

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

         8.02. Certain Matters Affecting the Trustee.

               Except as otherwise provided in Section 8.01:

                  (a)      The Trustee may request and rely upon and shall be
                           protected in acting or refraining from acting upon
                           any resolution, Officers' Certificate, certificate
                           of auditors or any other certificate, statement,
                           instrument, opinion, report, notice, request,
                           consent, order, appraisal, bond or other paper or
                           document reasonably believed by it to be genuine and
                           to have been signed or presented by the proper party
                           or parties;

                  (b)      The Trustee may consult with counsel and on the
                           advice of such counsel any Opinion of Counsel shall
                           be full and complete authorization and protection in
                           respect of any action taken or suffered or omitted
                           by it hereunder in good faith and in accordance
                           therewith;

                  (c)      The Trustee shall be under no obligation to exercise
                           any of the trusts or powers vested in it by this
                           Agreement or to make any investigation of matters
                           arising hereunder or to institute, conduct or defend
                           any litigation hereunder or in relation hereto at
                           the request, order or direction of any of the
                           Certificateholders, pursuant to the provisions of
                           this Agreement, unless such Certificateholders shall
                           have offered to the Trustee reasonable security or
                           indemnity against the costs, expenses and
                           liabilities which may be incurred therein or
                           thereby; nothing contained herein shall, however,
                           relieve the Trustee of the obligation, upon the
                           occurrence of an Event of Default (which has not
                           been cured or waived), to exercise such of the
                           rights and powers vested in it by this Agreement,
                           and to use the same degree of care and skill in
                           their exercise as a prudent man would exercise or
                           use under the circumstances in the conduct of his
                           own affairs;

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

                  (e)      Prior to the occurrence of an Event of Default with
                           respect to a Series hereunder and after the curing
                           or waiver of all Events of Default which may have
                           occurred, the Trustee shall not, with respect to
                           such 




                                     -83-

                           Series, be bound to make any investigation into the
                           facts or matters stated in any resolution,
                           certificate, statement, instrument, opinion, report,
                           notice, request, consent, order, approval, bond or
                           other paper or document, unless requested in writing
                           to do so by Holders of Certificates of such Series
                           evidencing Fractional Undivided Interests
                           aggregating not less than 25% of the applicable
                           Trust Fund; provided, however, that if the payment
                           within a reasonable time to the Trustee of the
                           costs, expenses or liabilities likely to be incurred
                           by it in the making of such investigation is, in the
                           opinion of the Trustee, not reasonably assured to
                           the Trustee by the security afforded to it by the
                           terms of this Agreement, the Trustee may require
                           reasonable indemnity against such expense or
                           liability as a condition to taking any such action.
                           The reasonable expense of every such reasonable
                           examination shall be paid by the Master Servicer or,
                           if paid by the Trustee, shall be repaid by the
                           Master Servicer upon demand; and

                  (f)      The Trustee may execute any of the trusts or powers
                           hereunder or perform any duties hereunder either
                           directly or by or through agents, affiliates,
                           custodians or attorneys; provided that the Trustee
                           shall remain directly liable with respect to the
                           execution of such trusts or powers and the
                           performance of such duties without regard to the
                           presence of such agents or attorneys.

         8.03. Trustee Not Liable for Certificates or Mortgage Loans.

         The recitals contained herein and in the Certificates, other than the
signature of the Trustee on the Certificates and the certificate of
authentication, shall be taken as the statements of the Seller or the Master
Servicer, as the case may be, and the Trustee assumes no responsibility for
their correctness. The Trustee makes no representations or warranties as to the
validity or sufficiency of this Agreement or of the Certificates or of any
Mortgage Loan or related document, other than the signature of the Trustee on
the Certificates and the Certificate of Authentication. The Trustee shall not
be accountable for the use or application by the Seller or the Master Servicer
of any of the Certificates or of the proceeds of such Certificates, or for the
use or application of any funds paid to the Loan Seller in respect of the
Mortgage Loans or deposited in or withdrawn from the Custodial Account, the
Excess Proceeds Account or the Certificate Account or any other account by or
on behalf of the Seller or the Master Servicer, other than any funds on deposit
with the Trustee held by or on behalf of the Trustee in accordance with Section
3.10.

         8.04. Trustee May Own Certificates.

         The Trustee in its individual or any other capacity may become the
owner or pledgee of Certificates with the same rights it would have if it were
not Trustee.

         8.05. Master Servicer to Pay Trustee's Fees.

         The Master Servicer covenants and agrees to pay to the Trustee from
time to time, and the Trustee shall be entitled to, reasonable compensation
(which shall not be limited by any provision of law in regard to the
compensation of a trustee of an express trust) for all services rendered by it
in the execution of the trusts hereby created and in the exercise and
performance of any of the powers and duties hereunder or of the Trustee. Except
as otherwise provided in this Agreement, the Trustee and any director, officer,
employee or agent of the Trustee shall be indemnified by any Trust Fund and
held harmless against any claim, loss, liability or expense incurred in
connection with any Event of Default, any breach of this Agreement, any claim
or legal action, including any pending or threatened claim or legal action
relating to the acceptance or administration of its trusts hereunder or the
Certificates, other than any claim, loss, liability or expense incurred in
connection with a breach constituting willful misfeasance, bad faith or
negligence of the Trustee in the performance of its duties hereunder or by
reason of reckless disregard of its obligations and duties hereunder. The
provisions of this Section 8.05 shall survive the resignation or removal of the
Trustee and the termination of this Agreement.

         The Master Servicer shall indemnify, defend, and hold harmless the
Trustee, its directors, employees, officers, and agents, from and against all
losses, claims, damages, and liabilities arising out of or incurred in
connection with the acceptance or performance of the trusts and duties herein
contained, except to the extent that such loss, claim, damage, or liability:
(a) shall be due to the willful misfeasance, bad faith, or negligence of the
Trustee, its directors, employees, officers, and agents, or (b) shall be one as
to which any Trust Fund is required to indemnify the Trustee. Indemnification
under this Section shall include reasonable fees and expenses of counsel and
expenses of litigation and shall survive the termination of this Agreement and
of the Master Servicer for actions or inactions by the Master Servicer when it
acted as such.

         8.06. Eligibility Requirements for Trustee.

         The Trustee hereunder shall at all times be a corporation or a
national banking association organized and doing business under the laws of any
state or the United States of America or the District of Columbia, authorized
under such laws to exercise corporate trust powers, having a combined capital
and surplus of at least $50,000,000 and subject to supervision or examination
by federal or state authority. In addition, the Trustee shall at all times be
acceptable to each Rating Agency rating the Securities. If such corporation
publishes reports of condition at least annually, pursuant to law or to the
requirements of the aforesaid supervising or examining authority, then for the
purposes of this Section the combined capital and surplus of such corporation
shall be deemed to be its combined capital and surplus as set forth in its most
recent report of condition so published. In case at any time the Trustee shall
cease to be eligible in accordance with the provisions of this Section, the
Trustee shall resign immediately in the manner and with the effect specified in
Section 8.07. The corporation or national banking association serving as
Trustee may have normal banking and trust relationships with the Seller and its
affiliates, Loan Seller and its affiliates or the Master Servicer and its
affiliates; provided, however, that such corporation cannot be an affiliate of
the Master Servicer other than the Trustee in its role as successor to the
Master Servicer.

<PAGE>   91

         8.07. Resignation and Removal of the Trustee.

         The Trustee may at any time resign and be discharged from the trusts
hereby created by giving notice thereof to the Seller, the Master Servicer and
to all Certificateholders; provided, that such resignation shall not be
effective until a successor trustee is appointed and accepts appointment in
accordance with the following provisions. Upon receiving such notice of
resignation, the Master Servicer shall promptly appoint a successor trustee who
meets the eligibility requirements of Section 8.06 by written instrument, in
duplicate, which instrument shall be delivered to the resigning Trustee and to
the successor trustee. A copy of such instrument shall be delivered to the
Certificateholders and the Master Servicer by the Seller. If no successor
trustee shall have been so appointed and have accepted appointment within 60
days after the giving of such notice of resignation, the resigning Trustee may
petition any court of competent jurisdiction for the appointment of a successor
trustee; provided, however, that the resigning Trustee shall not resign and be
discharged from the trusts hereby created until such time as the Rating Agency
rating the Certificates approves the successor trustee.

         If at any time the Trustee shall cease to be eligible in accordance
with the provisions of Section 8.06 and shall fail to resign after written
request therefor by the Master Servicer, or if at any time the Trustee shall
become incapable of acting, or shall be adjudged bankrupt or insolvent, or a
receiver of the Trustee or of its property shall be appointed, or any public
officer shall take charge or control of the Trustee or of its property or
affairs for the purpose of rehabilitation, conservation or liquidation, or if
the rating of the long-term debt obligations of the Trustee is not acceptable
to a Rating Agency, then the Master Servicer may remove the Trustee and appoint
a successor trustee who meets the eligibility requirements of Section 8.06 by
written instrument, in duplicate, which instrument shall be delivered to the
Trustee so removed and to the successor trustee. A copy of such instrument
shall be delivered to the Certificateholders and the Master Servicer by the
Seller.

         The Holders of Certificates of each Series evidencing Fractional
Undivided Interests aggregating not less than 51% of the Trust Fund for each
such Series may at any time remove the Trustee and appoint a successor trustee
by written instrument or instruments, in triplicate, signed by such Holders or
their attorneys-in-fact duly authorized, one complete set of which instruments
shall be delivered to the Master Servicer, one complete set to the Trustee so
removed and one complete set to the successor so appointed. A copy of such
instrument shall be delivered to the Certificateholders and the Master Servicer
by the Seller.

         Any resignation or removal of the Trustee and appointment of a
successor trustee pursuant to any of the provisions of this Section shall not
become effective until acceptance of appointment by the successor trustee as
provided in Section 8.08.

         The costs and expenses incurred in connection with the resignation or
removal of the Trustee shall be paid by the Trustee.

         8.08. Successor Trustee.

         Any successor trustee appointed as provided in Section 8.07 shall
execute, acknowledge and deliver to the Master Servicer and to its predecessor
trustee an instrument accepting such appointment hereunder, and thereupon the
resignation or removal of the predecessor trustee shall become effective and
such successor trustee, without any further act, deed or conveyance, shall







                                     -86-
<PAGE>   92

become fully vested with all the rights, powers, duties and obligations of its
predecessor hereunder, with the like effect as if originally named as trustee
herein. The predecessor trustee shall deliver to the successor trustee all
Mortgage Files and related documents and statements held by it hereunder, and
the Master Servicer and the predecessor trustee shall execute and deliver such
instruments and do such other things as may reasonably be required for more
fully and certainly vesting and confirming in the successor trustee all such
rights, powers, duties and obligations.

         No successor trustee shall accept appointment as provided in this
Section unless at the time of such acceptance such successor trustee shall be
eligible under the provisions of Section 8.06.

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

         8.09. Merger or Consolidation of Trustee.

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

         8.10. Appointment of Co-Trustee or Separate Trustee.

         Notwithstanding any other provisions hereof, at any time, for the
purpose of meeting any legal requirements of any jurisdiction in which any part
of any Trust Fund or property securing the same may at the time be located, the
Seller and the Trustee acting jointly shall have the power and shall execute
and deliver all instruments to appoint one or more Persons approved by the
Trustee to act as co-trustee or co-trustees, jointly with the Trustee, or
separate trustee or separate trustees, of all or any part of such Trust Fund,
and to vest in such Person or Persons, in such capacity, such title to such
Trust Fund, or any part thereof, and, subject to the other provisions of this
Section 8.10, such powers, duties, obligations, rights and trusts as the Seller
and the Trustee may consider necessary or desirable. If the Seller shall not
have joined in such appointment within 15 days after the receipt by it of a
request so to do, or in case an Event of Default shall have occurred and be
continuing, the Trustee alone shall have the power to make such appointment. No
co-trustee or separate trustee hereunder shall be required to meet the terms of
eligibility as a successor trustee under Section 8.06 hereunder and no notice
to Holders of Certificates of the appointment of co-trustee(s) or separate
trustee(s) shall be required under Section 8.08 hereof.

         In the case of any appointment of a co-trustee or separate trustee
pursuant to this Section 8.10 all rights, powers, duties and obligations
conferred or imposed upon the Trustee shall be conferred or imposed upon and
exercised or performed by the Trustee and such separate trustee or co-trustee
jointly, except to the extent that under any law of any jurisdiction in which
any particular act or acts 



                                     -87-
<PAGE>   93


are to be performed (whether as Trustee hereunder or as successor to the Master
Servicer hereunder), the Trustee shall be incompetent or unqualified to perform
such act or acts, in which event such rights, powers, duties and obligations
(including the holding of title to any Trust Fund or any portion thereof in any
such jurisdiction) shall be exercised and performed by such separate trustee or
co-trustee at the direction of the Trustee.

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

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


IX                               TERMINATION

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

         Subject to Section 9.02, the respective obligations and
responsibilities of the Seller, the Master Servicer and the Trustee created
hereby (other than the obligations of the Master Servicer to the Trustee
pursuant to Section 8.05 and of the Master Servicer to provide for and the
Trustee to make payments to Certificateholders as hereafter set forth) shall
terminate upon payment to the Certificateholders of all amounts held by or on
behalf of the Trustee and required to be paid to them hereunder following the
earlier to occur of (i) the repurchase by the Master Servicer or the Issuer of
all Mortgage Loans and each REO Property in respect thereof remaining in each
Trust Fund at a price at the Repurchase Price; and (ii) the final payment or
other liquidation (or any Advance with respect thereto) of the last Mortgage
Loan remaining in each Trust Fund (or the disposition of all REO Property in
respect thereof); provided, however, that in no event shall the trust created
hereby continue beyond the expiration of 21 years from the death of the last
survivor of the descendants of Joseph P. Kennedy, the late ambassador of the
United States to the Court of St. James, living on the date hereof. In the case
of any repurchase by the Master Servicer pursuant to clause (i), the Master
Servicer shall include in such repurchase price the amount of any Advances that
will be reimbursed to the Master Servicer pursuant to Section 3.11(iii) and the
Master Servicer shall exercise reasonable efforts to cooperate fully with the
Trustee in effecting such repurchase and the transfer of the Mortgage Loans and
related Mortgage Files and related records to the Master Servicer.





                                     -88-
<PAGE>   94

         The right of the Master Servicer or the Issuer to repurchase all
Mortgage Loans pursuant to (i) above shall be conditioned upon the aggregate
Stated Principal Balance of such Mortgage Loans at the time of any such
repurchase aggregating an amount equal to or less than 5% of the aggregate
Stated Principal Balance of the Mortgage Loans at the Cut-off Date and may be
exercised (a) by the Master Servicer on an Optional Termination Date on giving
to the Trustee and the Issuer not less the 5 Business Days' prior written
notice of the exercise of such option and (b) in the event that the Master
Servicer does not give such notice with respect to any Optional Termination
Date, by the Issuer on such Optional Termination Date on giving not less than 2
Business Days' prior written notice to the Trustee and the Master Servicer. If
such right is exercised, the Master Servicer or the Issuer, as applicable, upon
such repurchase shall provide to the Trustee, the certification required by
Section 3.16.

         Notice of any termination, specifying the Distribution Date upon which
the Certificateholders may surrender their Certificates to the Trustee for
payment of the final distribution and cancellation, shall be given promptly by
the Master Servicer or the Issuer, as applicable, by letter to the Trustee and
the Certificateholders mailed (a) in the event such notice is given in
connection with the Master Servicer's election to repurchase, not earlier than
the 15th day and not later than the 25th day of the month next preceding the
month of such final distribution or (b) otherwise during the month of such
final distribution on or before the Determination Date in such month, in each
case specifying (i) the Distribution Date upon which final payment of the
Certificates will be made upon presentation and surrender of Certificates at
the office of the Certificate Registrar therein designated, (ii) the amount of
any such final payment and (iii) that the Record Date otherwise applicable to
such Distribution Date is not applicable, payments being made only upon
presentation and surrender of the Certificates at the office of the Certificate
Registrar therein specified. In the event such notice is given in connection
with the Master Servicer's election to repurchase, the Master Servicer shall
deliver to the Trustee for deposit in the Certificate Account on the Business
Day immediately preceding the Distribution Date specified in such notice an
amount equal to the above-described repurchase price payable out of its own
funds. Upon presentation and surrender of the Certificates by the
Certificateholders, the Trustee shall distribute to the Certificateholders the
amount otherwise distributable on such Distribution Date. Upon certification to
the Trustee by a Servicing Officer, following such final deposit, the Trustee
shall promptly release the Mortgage Files as directed by the Master Servicer
for the remaining Mortgage Loans, and the Trustee shall execute all
assignments, endorsements and other instruments required by the Master Servicer
as being necessary to effectuate such transfer.

         In the event that all of the Certificateholders of a Series shall not
surrender their Certificates for cancellation within six months after the time
specified in the above-mentioned notice, the Trustee shall give a second notice
to the remaining Certificateholders instructing such Certificateholders to
surrender their Certificates for cancellation and receive the final
distribution with respect thereto. If within six months after the second notice
all of the Certificates shall not have been surrendered for cancellation, the
Trustee shall take reasonable steps as directed by the Seller, or appoint an
agent to take reasonable steps, to contact the remaining Certificateholders
concerning surrender of their Certificates, and the cost thereof shall be paid
out of the funds and other assets which remain subject hereto. If, within nine

         In addition and without prejudice to the foregoing, the respective
obligations of the Seller, the Master Servicer, the Loan Seller and the Trustee
created hereby may be terminated in respect of one or more Series of
Certificates on any date occurring after maturity of the Securities and the
release of the Certificates from any pledge securing the Securities.
Termination in the foregoing circumstances shall be effected upon receipt by
the Trustee of written notice from 100% of the Certificateholders of the
related Series of Certificate or Certificates requiring termination of this
Agreement in respect of such Series of Certificate or Certificates and
requesting the transfer of any Trust Fund to them in the manner specified in
such notice.

         9.02. Additional Termination Requirements.

         In the event the Master Servicer repurchases the Mortgage Loans as
provided in Section 9.01, the Lower REMIC and, in turn, the Upper REMIC shall
be terminated in accordance with the following additional requirements, unless
the Master Servicer, at its own expense, obtains for the Trustee an Opinion of
Counsel to the effect that the failure to comply with the requirements of this
Section 9.02 will not (i) result in the imposition of taxes on the net income
derived from "prohibited transactions" of either the Lower REMIC or the Upper
REMIC, as defined in Section 860F of the Code or (ii) cause either the Lower
REMIC or Upper REMIC to fail to qualify as a REMIC under the REMIC Provisions
at any time that any Certificates are outstanding:

                  (a)      The Trustee shall establish a 90-day liquidation
                           period for the REMICs and specify the first day of
                           such period in a statement attached to the final Tax
                           Returns of the REMICs pursuant to Treasury
                           Regulation Section 1.860F-1. The Trustee shall
                           satisfy all the requirements of a qualified
                           liquidation under Section 860F of the Code and any
                           regulations thereunder, as evidenced by an Opinion
                           of Counsel obtained at the expense of the Master
                           Servicer; and

                  (b)      During such 90-day liquidation period, and at or
                           prior to the time of making of the final payment on
                           the Certificates, the Trustee shall sell all of the
                           non-cash assets of the Lower REMIC and the Upper
                           REMIC for cash.

XI                          MISCELLANEOUS PROVISIONS

         11.01. Amendment.

         This Agreement may be amended from time to time by the Seller, the
Master Servicer, the Loan Seller and the Trustee without notice to or the
consent of any of the Certificateholders, (i) to cure any ambiguity, (ii) to
correct or supplement any provisions herein which may be defective or






                                     -90-
<PAGE>   96

inconsistent with any other provisions herein, (iii) to amend this Agreement in
any respect subject to the provisions below, (iv) to modify, eliminate, or add
to any of its provisions to such extent as shall be necessary or appropriate to
maintain the qualifications of the Upper REMIC and the Lower REMIC as REMICs
under the Code at all times that any Certificates are outstanding, or (v) if
such amendment, as evidenced by an Opinion of Counsel (provided by the Person
requesting such amendment) delivered to the Trustee, otherwise is reasonably
necessary to comply with any requirements imposed by the Code or any successor
or amendatory statute or any temporary or final regulation, revenue ruling,
revenue procedure or other written official announcement or interpretation
relating to federal income tax laws or any proposed such action which, if made
effective, would apply retroactively to any Trust Fund at least from the
effective date of such amendment; provided that such action (except any
amendment described in (iv) above) shall not, as evidenced by an Opinion of
Counsel (provided by the Person requesting such amendment) delivered to the
Trustee, adversely affect in any material respect the interests of any
Certificateholder (other than Certificateholders who shall consent to such
amendment).

         This Agreement may also be amended with respect to a Series from time
to time by the Seller, the Master Servicer, the Loan Seller and the Trustee
with the consent of the Holders of Certificates of such Series evidencing
Fractional Undivided Interests aggregating not less than 662/3% for the purpose
of adding any provisions to or changing in any manner or eliminating any of the
provisions of this Agreement or of modifying in any manner the rights of the
Holders of Certificates; provided, however, that no such amendment shall (i)
reduce in any manner the amount of, or delay the timing of, payments received
on Mortgage Loans which are required to be distributed on any Certificate
without the consent of the Holder of such Certificate, (ii) adversely affect in
any material respect the interests of the Holders of any Series of Certificates
in a manner other than as described in (i), without the consent of the Holders
of Certificates of such Series evidencing Fractional Undivided Interests equal
to 100% of the Trust Fund relating to such Series, or (iii) reduce the
aforesaid percentage of Certificates of a Series the Holders of which are
required to consent to any such amendment, without the consent of the Holders
of all Certificates then outstanding. Notwithstanding any other provision of
this Agreement, for purposes of the giving or withholding of consents pursuant
to this Section 11.01, Certificates registered in the name of the Loan Seller
or the Master Servicer or any affiliate thereof shall be taken into account
when calculating Fractional Undivided Interests with respect to matters
described in (i), (ii) and (iii) of this paragraph.

         Notwithstanding any contrary provision of this Agreement, the Trustee
shall not consent to any amendment to this Agreement unless it shall have first
received an Opinion of Counsel (provided by the Person requesting such
amendment) to the effect that such amendment will not result in the imposition
of any tax on the Securities pursuant to the REMIC Provisions or cause either
the Lower REMIC or the Upper REMIC to fail to qualify as a REMIC at any time
that any of the Certificates are outstanding.

         Promptly after the execution of any such amendment the Trustee shall
furnish a statement describing the amendment to each Certificateholder.

         It shall not be necessary for the consent of Certificateholders under
this Section 11.01 to approve the particular form of any proposed amendment,
but it shall be sufficient if such consent shall approve the substance thereof.
The manner of obtaining such consents and of evidencing the






                                     -91-
<PAGE>   97

authorization of the execution thereof by Certificateholders shall be subject
to such reasonable regulations as the Trustee may prescribe.

         Prior to executing any amendment pursuant to this Section, the Trustee
shall be entitled to receive an Opinion of Counsel (provided by the Person
requesting such amendment) to the effect that such amendment is authorized or
permitted by this Agreement. The cost of an Opinion of Counsel delivered
pursuant to this Section 11.01 shall be an expense of the party requesting such
amendment, but in any case shall not be an expense of the Trustee.

         The Trustee may, but shall not be obligated to enter into any
amendment pursuant to this Section that affects its rights, duties and
immunities under this Agreement or otherwise.

         11.02. Recordation of Agreement; Counterparts.

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

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

         11.03. Limitation on Rights of Certificateholders.

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

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

         No Certificateholder shall have any right by virtue of any provision
of this Agreement to institute any suit, action or proceeding in equity or at
law upon or under or with respect to this Agreement, unless such Holder
previously shall have given to the Trustee a notice of an Event of Default, or
of a default by the Loan Seller or the Trustee in the performance of any
obligation hereunder, and of the continuance thereof, as hereinbefore provided,
and unless also the Holders of 




                                     -92-
<PAGE>   98

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

         11.04. Governing Law.

         This Agreement and the Certificates shall be construed in accordance
with the laws of the State of New York without reference to any choice of law
doctrine (but with reference to Section 5- 1401 of the New York General
Obligations Law, which by its terms is applicable to this Agreement) the
obligations, rights and remedies of the parties hereunder shall be determined

         Pursuant to the Agreement, the Trustee will distribute on the Business
Day prior to the 25th day of the month (each, a "Distribution Date"),
commencing in October, 1997, to the Person in whose name this Certificate is
registered at the close of business on the last day (or if such last day is not
a Business Day, the Business Day immediately preceding such last day) of the
month next preceding the month of such distribution (the "Record Date"), such
Person's pro rata share (based on the aggregate Fractional Undivided Interest
evidenced by this Certificate) of the aggregate amount required to be
distributed to the Holders of the Series 1997-NAMC 3-A Certificates pursuant to
Section 4.01(b) of the Agreement. For the purposes hereof, amounts received in
connection with the liquidation of defaulted Mortgage Loans in the Loan Group
through Insurance Proceeds, foreclosure or trustee's sales proceeds or
otherwise, shall be deemed to be amounts received on Mortgage Loans in the Loan
Group.

         Distributions on this Certificate will be made by the Trustee by wire
transfer in immediately available funds for the account of the Person entitled
thereto as specified by such Person in accordance with the terms of the
Agreement or by such other method as shall be acceptable to both the Trustee
and such Person. Notwithstanding the above, the final distribution on this
Certificate will be made after due notice by the Trustee of the pendency of
such distribution and only upon presentation and surrender of this Certificate
at the office or agency maintained for that purpose by the Trustee in the City
of New York, State of New York.

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

         This Certificate is one of a duly authorized issue of Certificates
designated as set forth above (herein called the "Certificates") and
representing the Fractional Undivided Interest in the Trust Fund created
pursuant to the Agreement.

         The Certificates do not represent an obligation of, or an interest in,
CMCSC IV, the Master Servicer, or the Trustee and are not insured or guaranteed
by the Government National Mortgage Association or any other governmental
agency. The Certificates are limited in right of payment to certain collections
and recoveries respecting the Mortgage Loans in the Loan Group, all as more
specifically set forth hereinabove and in the Agreement.

         As provided in the Agreement, withdrawals from the Certificate Account
may be made by the Trustee from time to time for purposes other than
distributions to Certificateholders, such purposes including reimbursement to
the Master Servicer of certain expenses incurred, by them in connection with
the Mortgage Loans in the Loan Group.

         The Agreement permits, with respect to this Series and with certain
exceptions therein provided, the amendment thereof and the modification of the
rights and obligations of the Master Servicer and the rights of the
Certificateholders of this Series under the Agreement at any time by CMCSC IV,
the Master Servicer and the Trustee with the consent of the holders of
Certificates of this Series evidencing Fractional Undivided Interests
aggregating not less than 66% of the Trust Fund. Any such amendment or
modification shall be effective only as to this Series. Any consent to such an
amendment or modification by the holder of this Certificate shall be conclusive
and

  
                                     A-1-2

<PAGE>   106




binding on such holder and upon all future holders of this Certificate and of
any Certificate issued upon the transfer hereof or in exchange therefore or in
lieu hereof whether or not notation of such consent is made upon this
Certificate. The Agreement also permits the amendment thereof, in certain
limited circumstances, without the consent of the holders of any of the
Certificates of this Series.

         As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registerable in the
Certificate Register of the Certificate Registrar, which initially is The First
National Bank of Chicago, as Certificate Trustee, upon surrender of this
Certificate for registration of transfer at the office or agency maintained by
the Certificate Registrar, duly endorsed by, or accompanied by a written
instrument of transfer in form satisfactory to the Certificate Registrar, duly
executed by the holder hereof or such holder as attorney duly authorized in
writing, and thereupon one or more new Certificates of this Series of
authorized denominations evidencing the same aggregate Fractional Undivided
Interest in the Trust Fund will be issued to the designated transferee or
transferees.

         The Certificates are issuable only as registered Certificates without
coupons. As provided in the Agreement and subject to certain limitations
therein set forth, Certificates in this Series are exchangeable for new
Certificates of this Series of authorized denominations evidencing the same
aggregate Fractional Undivided Interest in the Trust Fund, as requested by the
holder surrendering the same.

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

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

         The obligations created by the Agreement and the Trust Fund shall
terminate upon (i) the later of the maturity or other liquidation (including
repurchase by the Loan Seller) of the last Mortgage Loan in the Loan Group or
the disposition of all property acquired upon foreclosure or deed in lieu of
foreclosure of any Mortgage Loan in the Loan Group, and (ii) the payment to
Certificateholders of this Series of all amounts held on their behalf and
required to be paid to them pursuant to the Agreement. The Master Servicer or
CMCSC IV may effect early retirement of the Certificates of this Series by
exercising its right under the Agreement to repurchase all the Mortgage Loans
in the Loan Group and the related Trust Property in the event that the
aggregate outstanding principal balance of the Mortgage Loans in the Loan Group
is less than five percent (5%) of the adjusted aggregate principal balance of
the Mortgage Loans in the Loan Group at the Cut-off Date.

         The Trustee's signature shall be for authentication purposes only and
neither the Trustee nor any person signing on its behalf shall have liability
on this Certificate (other than for the certificate of authentication).

         Section 2.01.  Reports and Notices

                  (a) In connection with the performance of its duties under
the Pooling and Servicing Agreement relating to the realization upon defaulted
Mortgage Loans, the Company as Master Servicer shall provide to the Purchaser
the following notices and reports:

                      (i) Within five Business Days after each Distribution Date
         (or included in or with the monthly statements to Securityholders
         pursuant to the Pooling and Servicing Agreement), the
         [Company][Trustee], shall provide to the Purchaser a report, using the
         same methodology and calculations in its standard servicing reports,
         indicating for the Trust the number of Mortgage Loans that are (A)
         thirty days, (B) sixty days, (C) ninety days or more delinquent or (D)
         in foreclosure, and indicating for each such Mortgage Loan the loan
         number and outstanding principal balance.

                     (ii) Prior to the Commencement of Foreclosure in
         connection with any Mortgage Loan, the Company shall provide the
         Purchaser with a notice (sent by telecopier) of such proposed and
         imminent foreclosure, stating the loan number and the aggregate amount
         owing under the Mortgage Loan. Such notice may be provided to the
         Purchaser in the form of a copy of a referral letter from such
         Servicer to an attorney requesting the institution of foreclosure.

                  (b) If requested by the Purchaser, the Company shall make its
servicing personnel available (during their normal business hours) to respond
to reasonable inquiries, by phone or in writing by facsimile, electronic, or
overnight mail transmission, by the Purchaser in connection with any Mortgage
Loan identified in a report under subsection (a) (i) (B), (a) (i) (C), (a) (i)
(D), or (a) (ii) which has been given to the Purchaser; provided, that (1) the
related Servicer shall only be required to provide information that is readily
accessible to its servicing personnel and is non-confidential and

  
                                      H-3

<PAGE>   129




(2) the related Servicer shall respond within five Business Days orally or in
writing by facsimile transmission.

                  (c) In addition to the foregoing, the Company shall provide
to the Purchaser such information as the Purchaser may reasonably request
provided, however, that such information is consistent with normal reporting
practices, concerning each Mortgage Loan that is at least ninety days
delinquent and each Mortgage Loan which has become real estate owned, through
the final liquidation thereof; provided, that the Company shall only be
required to provide information that is readily accessible to its servicing
personnel and is non-confidential provided, however, that the Purchaser will
reimburse the Company for any out of pocket expenses.

         Section 2.02.  Purchaser's Election to Delay Foreclosure Proceedings

                  (a) The Purchaser shall be deemed to direct the Company that
in the event that the Company does not receive written notice of the
Purchaser's election pursuant to subsection (b) below within 24 hours
(exclusive of any intervening non-Business Days) of transmission of the notice
provided by the Company under Section 2.01(a)(ii) subject to extension as set
forth in Section 2.02(b), it may proceed with the Commencement of Foreclosure
in respect of such Mortgage Loan in accordance with its normal foreclosure
policies without further notice to the Purchaser. Any foreclosure that has been
initiated may be discontinued (i) without notice to the Purchaser if the
Mortgage Loan has been brought current or if a refinancing or prepayment occurs
with respect to the Mortgage Loan (including by means of a short payoff
approved by the Company) or (ii) if the Company has reached the terms of a
forbearance agreement with the borrower. In such latter case, the Company may
complete such forbearance agreement unless instructed otherwise by the
Purchaser within two Business Days notification.

                  (b) In connection with any Mortgage Loan with respect to
which a notice under Section 2.01(a)(ii) has been given to the Purchaser, the
Purchaser may elect to instruct the Company to delay the Commencement of
Foreclosure until such time as the Purchaser determines that the Company may
proceed with the Commencement of Foreclosure. Such election must be evidenced
by written notice received within 24 hours (exclusive of any intervening
non-Business Days) of transmission of the notice provided by the Company under
Section 2.01(a)(ii). Such 24 hour period shall be extended for no longer than
an additional four Business Days after the receipt of the information if the
Purchaser requests additional information related to such foreclosure;
provided, however, that the Purchaser will have at least one Business day to
respond to any requested additional information. Any such additional
information shall (i) be provided only to the extent it is not confidential in
nature and (ii) be obtainable by the Company from existing reports,
certificates or statements or otherwise be readily accessible to its servicing
personnel. The Purchaser agrees that it has no right to deal with the mortgagor
during such period. However, if such servicing activities include acceptance of
a deed-in-lieu of foreclosure or short payoff, the Purchaser will be notified
and given two Business Days to respond.

                  (c) With respect to any Mortgage Loan as to which the
Purchaser has made an Election to Delay Foreclosure, the Purchaser shall obtain
a Current Appraisal as soon as practicable, but in no event more than 15
business days thereafter, and shall provide the Company with a copy of such
Current Appraisal.

<PAGE>   130




                  (d) Within two Business Days of making any Election to Delay
Foreclosure, the Purchaser shall remit by wire transfer to the Company, for
deposit in the Collateral Fund, an amount, as calculated by the Company, equal
to the sum of (i) 125% of the greater of the unpaid principal balance of the
Mortgage Loan and the value shown in the Current Appraisal referred to in
subsection (c) above (or, if such Current Appraisal has not yet been obtained,
the Company's estimate thereof, in which case the required deposit under this
subsection shall be adjusted upon obtaining such Current Appraisal), and (ii)
three months' interest on the Mortgage Loan at the applicable Mortgage Interest
Rate. If any Election to Delay Foreclosure extends for a period in excess of
three months (such excess period being referred to herein as the "Excess
Period"), within two Business Days the Purchaser shall remit by wire transfer
in advance to the Company for deposit in the Collateral Fund the amount of each
additional month's interest, as calculated by the Company, equal to interest on
the Mortgage Loan at the applicable Mortgage Interest Rate for the Excess
Period. The terms of this Agreement will no longer apply to the servicing of
any Mortgage Loan upon the failure of the Purchaser to deposit any of the above
amounts relating to the Mortgage Loan within two Business Days of the Election
to Delay Foreclosure or within two Business Days of the commencement of the
Excess Period subject to Section 3.01.

                  (e) With respect to any Mortgage Loan as to which the
Purchaser has made an Election to Delay Foreclosure, the Company may withdraw
from the Collateral Fund from time to time amounts necessary to reimburse the
related Servicer for all related Monthly Advances and Liquidation Expenses
thereafter made by such Servicer in accordance with the Pooling and Servicing
Agreement. To the extent that the amount of any such Liquidation Expenses is
determined by the Company based on estimated costs, and the actual costs are
subsequently determined to be higher, the Company may withdraw the additional
amount from the Collateral Fund. In the event that the Mortgage Loan is brought
current by the mortgagor and the foreclosure action is discontinued, the
amounts so withdrawn from the Collateral Fund shall be redeposited therein and
to the extent that reimbursement therefor from amounts paid by the mortgagor is
not prohibited pursuant to the Pooling and Servicing Agreement as of the date
hereof, applicable law or the related mortgage note. Except as provided in the
preceding sentence, amounts withdrawn from the Collateral Fund to cover Monthly
Advances and Liquidation Expenses shall not be redeposited therein or otherwise
reimbursed to the Purchaser. If and when any such Mortgage Loan is brought
current by the mortgagor, all amounts remaining in the Collateral Fund in
respect of such Mortgage Loan (after adjustment for all permitted withdrawals
and deposits pursuant to this subsection) shall be released to the Purchaser.

                  (f) With respect to any Mortgage Loan as to which the
Purchaser has made an Election to Delay Foreclosure, the Master Servicer shall
continue to service the Mortgage Loan in accordance with its customary
procedures (other than the delay in Commencement of Foreclosure as provided
herein). If and when the Purchaser shall notify the Company that it believes
that it is appropriate to do so, the Master Servicer may proceed with the
Commencement of Foreclosure. In any event, if the Mortgage Loan is not brought
current by the mortgagor by the time the loan becomes 6 months delinquent, the
Purchaser's election shall no longer be effective and at the Purchaser's
option, either (i) the Purchaser shall purchaser the Mortgage Loan from the
Trust at a purchase price equal to the fair market value as shown on the
Current Appraisal, to be paid by (x) applying any balance in the Collateral
Fund to such purchase price, and (y) to the extent of any deficiency, by wire
transfer if immediately available funds from the Purchaser to the Company for
deposit in the related Asset Proceeds Account; or (ii) the Master Servicer may
proceed with the Commencement of Foreclosure.

                  (g) Upon the occurrence of a liquidation with respect to any
Mortgage Loan as to which the Purchaser made an Election to Delay Foreclosure
and as to which the Master Servicer proceeded with the Commencement of
Foreclosure in accordance with subsection (f) above, the Company shall
calculate the amount, if any, by which the value shown on the Current Appraisal
obtained under subsection (c) exceeds the actual sales price obtained for the
related Mortgaged Property (net of Liquidation Expenses and accrued interest
related to the extended foreclosure period), and the Company shall withdraw the
amount of such excess from the Collateral Fund, shall remit the same to the
Trust and in its capacity as Master Servicer shall apply such amount as
additional Liquidation Proceeds pursuant to the Pooling and Servicing
Agreement. After making such withdrawal, all amounts remaining the Collateral
Fund in respect of such Mortgage Loan (after adjustment for all permitted
withdrawals and deposits pursuant to this Agreement) shall be released to the
Purchaser.

         Section 2.03.  Purchaser's Election to Commence Foreclosure Proceedings

                  (a) In connection with any Mortgage Loan identified in a
report under Section 2.01(a)(i)(B), the Purchaser may elect to instruct the
Company to proceed with the Commencement of Foreclosure as soon as practicable.
Such election must be evidenced by written notice received by the Company by
5:00 p.m., [New York City] time, on the third Business Day following the
delivery of such report under Section 2.01(a)(i).

                  (b) Within two Business Days of making any Election to
Foreclosure, the Purchaser shall remit to the Company, for deposit in the
Collateral Fund, an amount, as calculated by the Company, equal to 125% of the
current unpaid principal balance of the Mortgage Loan and three months interest
on the Mortgage Loan at the applicable Mortgage Interest Rate. If any when any
such Mortgage Loan is brought current by the mortgagor, all amounts in the
Collateral Fund in respect of such Mortgage Loan (after adjustment for all
permitted withdrawals and deposits pursuant to this Agreement) shall be
released to the Purchaser and to the extent that reimbursement therefor from
amounts paid by the mortgagor is not prohibited pursuant to the Pooling and
Servicing Agreement as of the date hereof, applicable law or the related
mortgage note. The terms of this Agreement will no longer apply to the
servicing of any Mortgage Loan upon the failure of the Purchaser to deposit the
above amounts relating to the Mortgage Loan within two Business days of the
Election to Foreclose subject to Section 3.01.

                  (c) With respect to any Mortgage Loan as to which the
Purchaser has made an Election to Foreclose, the Master Servicer shall continue
to service the Mortgage Loan in accordance with its customary procedures (other
than Commencement of Foreclosure as provided herein). In connection therewith,
the Company shall have the same rights to make withdrawals for Monthly Advances
and Liquidation Expenses from the Collateral Fund as are provided under Section
2.02(e), and the Company shall make reimbursements thereto the limited extent
provided under such subsection in accordance with its customary procedures. The
Company shall not be required to proceed with the Commencement of Foreclosure
if (i) the same is stayed as a result of the mortgagor's bankruptcy or is
otherwise barred by applicable law, or to the extent that all legal conditions
precedent thereto have not yet been complied with, or (ii) the Company believes
there is a breach of representations or warranties by the Company or the Loan
Seller, which may result in a repurchase or substitution of such Mortgage Loan,
or (iii) the Company reasonably believes the Mortgaged

  
                                      H-6

<PAGE>   132




Property may be contaminated with or affected by hazardous wastes or hazardous
substances (and, without limiting the Master Servicer's right not to proceed
with the Commencement of Foreclosure, the Company supplies the Purchaser with
information supporting such belief). Any foreclosure that has been initiated
may be discontinued (x) without notice to the Purchaser if the Mortgage Loan
has been brought current or if a refinancing or prepayment occurs with respect
to the Mortgage Loan (including by means of a short payoff approved by the
Purchaser) or (y) with notice to the Purchaser if the Master Servicer has
reached the terms of a forbearance agreement unless instructed otherwise by the
Purchaser within two Business Days of such notification. Any such information
shall be based upon a decision that such forbearance agreement is not in
conformity with reasonable servicing practices.

                  (d) Upon the occurrence of a liquidation with respect to any
Mortgage Loan as to which the Purchaser made an Election to Foreclose and as to
which the Master Servicer proceeded with the Commencement of Foreclosure in
accordance with subsection (c) above, the Company shall calculate the amount,
if any, by which the unpaid principal balance of the Mortgage Loan at the time
of liquidation (plus all unreimbursed interest and servicing advances and
Liquidation Expenses in connection therewith other than those paid from the
Collateral Fund) exceeds the actual sales price obtained for the related
Mortgaged Property, and the Company shall withdraw the amount of such excess
from the Collateral Fund, shall remit the same to the Trust and in its capacity
as Master Servicer shall apply such amount as additional Liquidation Proceeds
pursuant to the Pooling and Servicing Agreement. After making such withdrawal,
all amounts remaining in the Collateral Fund (after adjustment for all
withdrawals and deposits pursuant to subsection (c) of such Mortgage Loan shall
be released to the Purchaser.

         Section 2.04.  Termination

                  (a) With respect to all Mortgage Loans included in the Trust,
the Purchaser's right to make any Election of Delay Foreclosure or any Election
to Foreclose and the Company's obligations under Section 2.01 shall terminate
(i) at such time as the Security Principal Balance of the Class B Securities
has been reduced to zero, (ii) if the greater of (x) [43]% (or such lower or
higher percentage that represents the Master Servicer's actual historical loss
experience with respect to the Mortgage Loan in the related pool as determined
by the Company) of the aggregate principal balance of all Mortgage Loans that
are in foreclosure or are more than 90 days delinquent on a contractual basis
and REO properties or (y) the aggregate amount that the Company estimates
through the normal servicing practices of the related Servicer will be required
to be withdrawn from the Collateral Fund with respect to Mortgage Loans as to
which the Purchaser has made an Election to Delay Foreclosure or an Election to
Foreclosure, exceeds (z) the then-current principal balance of the Class B
Securities, (iii) upon any transfer by the Purchaser of any interest (other
than the minority interest therein, but only if the transferee provides written
acknowledgment to the Company of the Purchaser's right hereunder and that such
transferee will have no rights hereunder) in the Class B Securities (whether or
not such transferee is registered under the Pooling and Servicing Agreement),
including any such transfer in connection with a termination of the Trust or
(iv) any breach of the terms of this Agreement by the Purchaser.

                  (b) Except as set forth in 2.04(a), this Agreement and the
respective rights, obligations and responsibilities of the Purchaser and the
Company hereunder shall terminate upon the later to occur of (i) the final
liquidation of the last Mortgage Loan as to which the Purchaser made any
Election to Delay Foreclosure or any Election to Foreclose and the withdrawal
of all remaining amounts in the Collateral Fund as provided herein and (ii) ten
Business Days' notice. The Purchaser's right to make an election pursuant to
Section 2.02 or Section 2.03 hereof with respect to a particular Mortgage Loan
shall terminate if the Purchaser fails to make any deposit required pursuant to
Section 2.02(d) or 2.03(b) or if the Purchaser fails to make any other deposit
to the Collateral Fund pursuant to this Agreement.

                                  ARTICLE III

                       COLLATERAL FUND; SECURITY INTEREST

         Section 3.01.  Collateral Fund

         Upon receipt from the Purchaser of the initial amount required to be
deposited in the Collateral Fund pursuant to Article II, the Company shall
establish and maintain with the Trustee as a segregated account on its books
and records an account (the "Collateral Fund"), entitled "North American
Mortgage Company, as Master Servicer, for the benefit of registered holders of
Financial Asset Securitization, Inc., Mortgage Participation Securities, Series
1997-NAMC 3." Amounts held in the Collateral Fund shall continue to be the
property of the Purchaser, subject to the first priority interest granted
hereunder for the benefit of the Securityholders, until withdrawn from the
Collateral Fund pursuant to Section 2.02 or 2.03 hereof. The Collateral Fund
shall be an "outside reserve fund" within the meaning of the REMIC Provisions,
beneficially owned by the Purchaser for federal income tax purposes. All
income, gain, deduction or loss with respect to the Collateral Fund shall be
that of the Purchaser. All distributions from the Trust Fund to the Collateral
Fund shall be treated as distributed to the Purchaser as the beneficial owner
thereof.

         Upon the termination of this Agreement and the liquidation of all
Mortgage Loans as to which the Purchaser has made any Election to Delay
Foreclosure or any Election to Foreclose pursuant to Section 2.04 hereof, the
Company shall distribute to the Purchaser all amounts remaining in the
Collateral Fund (after adjustment for all deposits and permitted withdrawals
pursuant to this Agreement) together with any investment earnings thereon. In
the event the Purchaser has made any Election to Delay Foreclosure or any
Election to Foreclose, prior to any distribution to the Purchaser of all
amounts remaining in the Collateral Fund, funds in the Collateral Fund shall be
applied consistent with the terms of this Agreement.

         Section 3.02.  Collateral Fund Permitted Investments

         The Company shall, at the written direction of the Purchaser, invest
the funds in the Collateral Fund in Collateral Fund Permitted Investments. Such
direction shall not be changed more frequently than quarterly. In the absence
of any direction, the Company shall select such investments in accordance with
the definition of Collateral Fund Permitted Investments in its discretion.

<PAGE>   134




         All income and gain realized from any investments as well as any
interest earned on deposits in the Collateral Fund (net of any losses on such
investments) and any payments of principal made in respect of any Collateral
Fund Permitted Investment shall be deposited in the Collateral Fund upon
receipt. All costs and realized losses associated with the purchase and sale of
Collateral Fund Permitted Investments shall be borne by the Purchaser and the
amount of net realized losses shall be deposited by the Purchaser in the
Collateral Fund promptly upon realization. The Company shall periodically (but
not more frequently than monthly) distribute to the Purchaser upon request an
amount of cash, to the extent cash is available therefore in the Collateral
Fund, equal to the amount by which the balance of the Collateral Fund, after
giving effect to all other distributions to be made from the Collateral Fund on
such date, exceeds the Required Collateral Fund Balance. Any amounts so
distributed shall be released from the lien and security interest of this
Agreement.

         Section 3.03.  Grant of Security Interest

         The Purchaser hereby grants to the Company for the benefit of the
Securityholders under the Pooling and Servicing Agreement a security interest
in and lien on all of the Purchaser's right, title and interest, whether now
owned or hereafter acquired, in and to: (1) the Collateral Fund, (2) all
amounts deposited in the Collateral Fund and Collateral Fund Permitted
Investments in which such amounts are invested (and the distributions and
proceeds of such investments) and (3) all cash and non-cash proceeds of any of
the foregoing, including proceeds of the voluntary conversion thereof (all of
the foregoing collectively, the "Collateral").

         The Purchaser acknowledges the lien on the security interest in the
Collateral for the benefit of the Securityholders. The Purchaser shall take all
actions requested by the Company as may be reasonably necessary to perfect the
security interest created under this Agreement in the Collateral and cause it
to be prior to all other security interests and liens, including the execution
and delivery to the Company for filing of appropriate financing statements in
accordance with applicable law. The Company shall file appropriate continuation

         Section 3.04.  Collateral Shortfalls

         In the event that amounts on deposit in the Collateral Fund at any
time are insufficient to cover any withdrawals therefrom that the Company is
then entitled to make hereunder, the Purchaser shall be obligated to pay such
amounts to the Company immediately upon demand. Such obligation shall
constitute a general corporate obligation of the Purchaser. The failure to pay
such amounts within two business Days of such demand (except for amounts to
cover interest on a Mortgage Loan pursuant to Sections 2.02(d) and 2.03(b)),
shall cause an immediate termination of the Purchaser's right to make any

obligations under this Agreement with respect to all Mortgage Loans to which
such insufficiencies relate, without the necessity of any further notice or
demand on the part of the Company.
