further amended by Post Effective Amendment No. 2 thereto filed with the
Commission on December 13, 1993, and as further amended by Post Effective
Amendment No. 3 thereto filed with the Commission on February 14, 1994
(collectively, the "Registration Statement"), pursuant to which the Registrant
registered $4,000,000,000 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 March 27, 1998 and the

       On March 31, 1998, the Registrant caused the issuance and sale of
approximately $593,796,659 aggregate initial principal amount of Bonds.  The
Bonds are collateralized by mortgage pass-through certificates (the

entire pools of certain conventional, fixed-rate, fully-amortizing, one-to
four-family, first lien mortgage loans (the "Mortgage Loans") originated or
acquired by (i) Cendant Mortgage Corporation  ("Cendant"), Bank of America, FSB
("BAFSB"), and (iii) Bank of America National Trust and Savings Association
("BANTSA").  Cendant, BAFSB and BANTSA are referred to herein collectively as
the "Loan Sellers".  The Certificates were created pursuant to a Pooling and
Servicing Agreement dated as of March 1, 1998 (the "Pooling and Servicing
Agreement") by and among the Registrant, as Depositor, Cendant and BAFSB, as
Master Servicers, First Chicago National Processing Corporation, as Custodian,
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 March 1, 1998 (the
"Indenture"), as supplemented by the Series 1998-1 Supplement thereto dated as
of March 31, 1998 (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 Offered Bonds (as defined in the Prospectus), having an aggregate
principal balance of $589,490,892, have been sold by the Registrant to Bear,
Stearns & Co. Inc. ("Bear, Stearns") pursuant to an Underwriting Agreement
dated as of March 27, 1998 (the "Underwriting Agreement"), as supplemented by a
Terms Agreement dated as of March 27, 1998, each among Bear, Stearns, the

New York, New York  10167

Ladies and Gentlemen:

       CMC Securities Corporation III (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 March 1, 1998 (the "Original Indenture"), between the Company and The First
National Bank of Chicago, as trustee (the "Indenture 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 Indenture 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 Indenture 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. 33-47913), 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 February 16, 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 amended to the date hereof and as 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




                                     -2-
<PAGE>   3
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
(on behalf of itself and its wholly owned subsidiary, Capstead Capital
Corporation ("CCC"), as applicable), 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 Indenture 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 will be
       so qualified and will conform in all material respects with the
       requirements of the 1939 Act and the 1939 Act Regulations.





                                      -3-
<PAGE>   4
              (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 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,





                                      -4-

       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, the Original
       Indenture, the related Series Supplement, the related pooling and
       servicing agreement ("Pooling and Servicing Agreement"), the related
       mortgage loan purchase agreement executed by CCC ("Mortgage Loan

       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

       necessary action (corporate and other); this Agreement, the Original
       Indenture, the related Series Supplement, the related Pooling and
       Servicing Agreement, the related Mortgage Loan Purchase Agreement and
       each Assignment Agreement have each been, and the Terms Agreement, when
       executed and delivered, will have been, duly executed and delivered by
       the Company, CCC 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 Original
       Indenture, the related Series Supplement, the related  Pooling and
       Servicing Agreement, the related Mortgage Loan Purchase Agreement, the
       related Assignment Agreements or the

<PAGE>   6
       Terms Agreement, the incurrence of the obligations herein or therein set
       forth, nor the consummation of the 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, CCC or Capstead, as applicable,
       pursuant to any contract, indenture, mortgage, loan agreement, note,
       lease or other instrument to which the Company, CCC 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, CCC
       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 time of execution of the related Pooling and
       Servicing Agreement, the Company will own the Mortgage Loans being
       transferred to the Trust pursuant to such Pooling and Servicing
       Agreement, free and clear of any lien, adverse claim, mortgage, charge,
       pledge or other encumbrance or security interest, and will not have
       assigned to any other person any of its right, title or interest in such
       Mortgage Loans; and, upon the execution of the related Pooling and
       Servicing Agreement, the Company will transfer all its right, title and
       interest in such Mortgage Loans to the Certificate Trustee.

              (p)    As of the Closing Time with respect to a Series of Bonds,
       the Mortgage Loans will be duly and validly assigned in blank or to the
       Certificate Trustee (or its nominee), the related Mortgage Notes will be
       endorsed in blank or to the Certificate Trustee (or its nominee) and
       delivered to the Certificate Trustee or to an agent on its behalf and,
       where required in order to transfer all right, title and interest to a
       Mortgage Loan, upon the





                                      -6-
<PAGE>   7
       recordation of assignments to the Certificate Trustee of the related
       mortgages in the public records in which such mortgage shall have been
       recorded, the Certificate Trustee will own each such Mortgage Loan,
       subject to no prior lien, mortgage, security interest, pledge, charge or
       other encumbrance, except as permitted under the related Pooling and
       Servicing Agreement.

              (q)    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 Indenture
       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 Indenture Trustee under the Indenture, and
       will have duly authorized such assignment, pledge and delivery to the
       Indenture Trustee by all necessary corporate action.

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

              (s)    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 Indenture
       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 Indenture 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.

              (t)    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.

              (u)    The related Pooling and Servicing Agreement will not be
       required to be qualified under the Trust Indenture Act of 1939, as
       amended.

              (v)    The representations and warranties made by the Company in
       the Indenture and the related Pooling and Servicing Agreement and made
       in any Officers' Certificate of the Company delivered pursuant to the
       Original Indenture or the related Pooling and Servicing Agreement will
       be true and correct at the time made and at the Closing Time.

              (w)    The related 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.

              (x)    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.

              (y)    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 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.

              (z)    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.

              (aa)   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.

              (bb)   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





                                      -8-
<PAGE>   9
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 11 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:

              (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 materials provided by you
       pursuant to Section 8 below ("Section 8 Materials") 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 Section 8 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 Section 8 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





                                      -9-
<PAGE>   10
       sentences, the Company shall have no obligation to file any 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 or the PSA 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 Section 8 Materials); 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 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





                                      -10-
<PAGE>   11
       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 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 Section 8 Materials incorporated by reference in the
       Final Prospectus other than any amendments or supplements of such
       Section 8 Materials 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





                                      -11-
<PAGE>   12
       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

                     (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 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 nor
       Capstead or any subsidiary thereof will, without your prior written
       consent or as may be otherwise permitted by such Terms Agreement, offer
       or sell, or enter into any agreement to sell to the public, any
       mortgage-related or





                                      -12-
<PAGE>   13
       mortgage-backed securities issued by any of them which are similar to
       the Bonds.  The provisions of this subparagraph (n) do not apply to
       securities issued or guaranteed by GNMA, FNMA or FHLMC.

       SECTION 4.    Payment of Expenses.  Unless otherwise specified in the
applicable Terms Agreement, the Company will pay, and Capstead will cause the
Company to pay, the following expenses incident to the performance of the
Company's obligations under this Agreement and the applicable Terms Agreement:
(i) the filing of the Registration Statement with respect to the Bonds and all
amendments thereto, (ii) the printing or photocopying and delivery to the

              (a)    At the applicable Closing Time (i) no stop order

       this Agreement shall not have been lowered since that date 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 was required to
       be delivered to a purchaser of the Bonds to be underwritten at such time
       pursuant to this Agreement 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 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.

                     (ii)  The Company has corporate power and authority 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 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 duly executed and delivered by
              the Company and, assuming due authorization, execution and
              delivery of the Indenture by the Indenture Trustee, when
              authenticated by the Indenture 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 Indenture Trustee under the Indenture, and had
              duly authorized such assignment, pledge and delivery to the
              Indenture Trustee by all necessary corporate action.

                     (xiii)  Immediately prior to the grant to the Indenture
              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 Indenture 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 Indenture 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





                                      -16-
<PAGE>   17
              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 Indenture Trustee in the
              Initial Collateral as 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 Indenture 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





                                      -17-
<PAGE>   18
              Prospectus of statutes, legal and governmental proceedings and
              contracts and other documents are accurate and fairly present the
              information required to be shown.

                     (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:





                                      -18-
<PAGE>   19
                     (i)   Capstead has been duly organized and is validly
              existing as a corporation, in good standing under the laws of the
              jurisdiction of its organization with corporate power and
              authority to own, lease and operate its properties and conduct
              its business as described in the applicable Final Prospectus.

                     (ii)  Capstead is not, nor will it be, as a result of its
              entering into this Agreement and consummating the transactions
              contemplated hereby, in violation of its charter or bylaws, and
              to the best of such counsel's knowledge, 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.

                     (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 of the
              transactions contemplated herein and therein have been duly
              authorized by Capstead by all necessary corporate action; and

       have been furnished with such documents and opinions (including copies

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 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





                                      -21-
<PAGE>   22
              preparation of either (x) any Section 8 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 Section
              8 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 Section 8 Materials (or any written or electronic
              materials on which the Section 8 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 Section 8
              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 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 paragraphs (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





                                      -22-
<PAGE>   23
       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 Section 8 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)    Promptly after receipt by an indemnified party under
       Section 6 of notice of the commencement of any action, such indemnified
       party will, if a claim in respect thereof is to be made against an
       indemnifying party under this Section 6, notify such indemnifying party
       in writing of the commencement thereof; but the omission so to notify
       such indemnifying party will not relieve it from any liability which it
       may have to any indemnified party otherwise than under this Section 6.
       In case any such action is brought against any indemnified party, and it
       notifies the indemnifying party or parties of the commencement thereof,
       the indemnifying party or parties will be entitled to participate
       therein, and to the extent that they may elect by written notice
       delivered to an indemnified party promptly after receiving the aforesaid
       notice from such indemnified party, to assume the defense thereof, with
       counsel satisfactory to such indemnified party; provided, however, that
       if the defendants in any such action include both an indemnified party
       and an indemnifying party and such indemnified party shall have
       reasonably concluded that there may be legal defenses available to it
       and/or other indemnified parties which are different from or addition to
       those available to any indemnifying party, such indemnified party or
       parties shall have the right to select separate counsel to assert such
       legal defenses and to otherwise participate in the defense of such
       action on behalf of such indemnified party or parties.  Upon receipt of
       notice from an indemnifying party or parties to such indemnified party
       of their election so to assume the defense of such action and approval
       by such indemnified party or counsel, such indemnifying party or parties
       will not be liable to such indemnified party under this Section 6 for
       any legal or other expenses subsequently incurred by such indemnified
       party in connection with the defense thereof unless (i) such indemnified
       party shall have employed separate counsel in connection with the
       assertion of legal defenses in accordance with the proviso to the next
       preceding sentence (it being understood, however, that the indemnifying
       party or parties shall not be liable for the expenses of more than one
       separate counsel approved by the indemnified party or parties in the
       case of subparagraph (a) or (b) above, representing the indemnified
       parties under subparagraph





                                      -23-
<PAGE>   24
       (a) or (b) above, who are parties to such action), (ii) the indemnifying
       party or parties shall not have employed counsel satisfactory to the
       indemnified party or parties to represent such indemnified party or
       parties within a reasonable time after notice of commencement of the
       action or (iii) the indemnifying party or parties have authorized the
       employment of counsel for an indemnified party at the expense of the
       indemnifying parties; and except that, if clause (i) or (iii) is
       applicable, such liability shall be only in respect of the counsel
       referred to in such clause (i) or (iii).

              (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 Section 8 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 Section 8
       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





                                      -24-
<PAGE>   25
       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 account any gains or losses realized by
       such Underwriter in any hedging transactions directly related to the
       Bonds) over (ii) the proceeds received by the Company in respect of the
       Bonds purchased by such Underwriter.

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 and Structural Term Sheets.  (a) As
soon as practicable and in no event later than 3:00 p.m. Dallas, Texas time one
Business Day before the date on which the Final Prospectus relating to the
Bonds of a Series is required to be filed by the Company with the Commission
pursuant to Rule 424 under the 1933 Act, you shall deliver to the Company five

and Kidder Structured Asset Corporation and the no-action letter dated May 27,
1994 issued by the Division of Corporation Finance of the Commission to the
Public Securities Association (together, the "Kidder Letters") and the filing
of such material is a condition of the relief granted in such letter (such
materials being the "Computational Materials"), and (ii) "Structural Term
Sheets" within the meaning of the no-action letter dated February 17, 1995
issued by the Division of Corporation Finance of the Commission to the Public

"Structural Term Sheets").  Each delivery of Computational Materials or
Structural Terms Sheets 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., 1717 Main Street, Suite 3700, Dallas, Texas 75201,
or such other address specified by such counsel to you in writing, and one copy

              (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

              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

              which the Computational Materials or Structural Term Sheets 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 Structural Term Sheets (or any such written or
              electronic materials furnished to prospective investors on which
              the Computational Materials or Structural Term Sheets are based)
              did not and 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.

Notwithstanding the foregoing, you make no representation or warranty as to
whether any Computational Materials or Structural Term Sheets (or any written
or electronic materials on which the Computational Materials or Structural Term
Sheets 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 or
Structural Term Sheets to any prospective investor, and agree that any
Computational Materials or Structural Term Sheets 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 or
Structural Term Sheets 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





                                      -26-
<PAGE>   27
Prospectus as a result of an untrue statement of a material fact contained in
any Computational Materials or Structural Term Sheets 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 relating to any Computational Materials or Structural Term Sheets 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 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 or Capstead, 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 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 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





                                      -28-
<PAGE>   29
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.

       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
Company shall be directed to its agent for service set forth on the cover page
of the Registration Statement, notices to the Company shall be directed to it
at CityPlace Center East, 2711 N. Haskell Avenue, Suite 900, Dallas, Texas

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

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

hereto and thereto and their respective successors, and said controlling
persons and officers and directors and their heirs and legal representatives,
and for the benefit of no other person, firm or corporation.  No purchaser of
Bonds from any Underwriter shall be deemed to be a successor by reason merely
of such purchase.

       SECTION 14.  GOVERNING LAW AND TIME.  THIS AGREEMENT AND EACH TERMS
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.

         Rate. Unless the related Series Supplement provides otherwise, all
         funds assumed to be reinvested at the applicable Assumed Reinvestment
         Rate shall be assumed to remain so invested until the Business Day next
         preceding the Principal Reduction Date or Interest Payment Date on
         which they are required to be available in the related Collection
         Account for application, in accordance with the terms hereof and of the
         related Series Supplement, to payments of principal of or interest on
         the Bonds of the related Series. All funds eligible to be invested
         pursuant to a Qualified GIC shall (subject, however, to any limitations
         contained in such Qualified GIC) be assumed to be invested thereunder
         on the next Business Day after the assumed date of receipt and to
         remain invested thereunder until the Business Day preceding the
         Principal Reduction Date on which such funds are, or might be, required
         to be available for application pursuant to this Indenture or the
         applicable Series Supplement.

                                    THE BONDS

         SECTION 2.1       Forms Generally.

         The Bonds of each Series and the Trustee's certificate of
authentication thereon shall be in substantially the form or forms set forth in
the Series Supplement pursuant to which such Bonds are constituted and as may in
the Issuer's judgment be necessary, appropriate or convenient to permit the
Bonds to be issued and sold to or held in bearer form by non-United States
Persons, to establish entitlement to an exemption from United States withholding
tax or reporting requirements with respect to payments on the Bonds, or to
comply, or facilitate compliance, with other applicable laws. Each Series of
Bonds may have such letters, numbers or other marks of identification and such
legends or endorsements placed thereon as may be required to comply with the
rules of any securities exchange on which the Bonds may be listed, or as may,
consistently herewith, be determined by the officers executing such Bonds, as
evidenced by their execution thereof. While Bonds may contain the
above-referenced provisions with respect to Bonds issued in bearer form, no
Bonds may actually be issued in bearer form until the Issuer and the Trustee
shall have entered into an appropriate supplemental indenture pursuant to
Section 9.1(8) providing for such issuance. Any portion of the text of any Bond
may be set forth on the reverse thereof with an appropriate reference on the
face of the Bond.

         The definitive Bonds shall be printed, lithographed or engraved or
produced by any combination of these methods on steel engraved borders or may be
produced in any other manner permitted by the rules of any securities exchange
on which the Bonds may be listed, all as determined by the officers executing
such Bonds, as evidenced by their execution thereof.

         Each Class of Book Entry Bonds shall be evidenced by one or more
certificates physically held by the Clearing Agency, which certificates may be
typewritten, printed, lithographed, mimeo graphed or otherwise produced.

         SECTION 2.2       Form of Trustee's Certificate of Authentication.

         The form of the Trustee's certificate of authentication is as follows:

         This is one of the Bonds referred to in the within-mentioned Indenture.

         SECTION 2.3       Bonds Issuable in Series and Classes; General 
                           Provisions with Respect to Principal and Interest 
                           Payments.

         The aggregate principal amount of Bonds that may be issued pursuant to
this Indenture is unlimited.

         The Bonds may, as provided herein, at the election of and as 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 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.




                                      -29-

<PAGE>   40




         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 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

                  if any, the number of Classes of Formula Rate Bonds, if any,
                  the number of Classes of Senior Bonds, if any, the number of
                  Classes of Junior Bonds, if any, and the maximum aggregate
                  principal amount of Bonds of each such Class which may be
                  issued;

         (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, the method of calculating the Bond

                  Interest Rate borne at any time by such Variable Rate Bonds;
                  and if such Series of 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;

         (5)      the Stated Maturity of the final installment of principal of
                  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;

         (9)      if such Series of Bonds includes a Class of Formula Rate
                  Bonds, restrictions relating to the transfer of such Class of
                  Formula Rate Bonds;

         (10)     whether the Bonds of such Series may be authenticated by an
                  Authenticating Agent, and, if so, the Person appointed as
                  Authenticating Agent for such Series;

         (11)     the Interest Payment Dates, Principal Payment Dates and 
                  Special Payment Dates;

                  Collection Account for such Series;

         (13)     whether a Qualified GIC is to be Granted to the Trustee with
                  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;

         (14)     any items required to be delivered to the Trustee on the
                  Closing Date for such Series pursuant to the last paragraph of
                  Section 2.12;

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

                  of the assumptions set forth in Section 1.3, and, if
                  applicable, any modifications to such assumptions to be used

         (23)     any other provisions expressing or referring to the terms and
                  conditions upon which the Bonds of that Series are to be
                  issued under this Indenture; and

         (24)     The Series Supplement relative to each Series of Bonds secured
                  by assets in respect of which one or more REMIC elections have
                  been made shall specify each of the following in respect of

                                      (i)   the "Startup Day" for the purposes 
                           of the REMIC Provisions;




                                      -35-

<PAGE>   46





                                     (ii) the "latest possible maturity date" of
                           the regular interests of such REMIC for the purposes
                           of Section 860(G)(a)(1) of the Code;

                                    (iii) each regular interest and Residual
                           Interest in such REMIC; and

                                     (iv) the Prepayment Assumption in respect
                           of such Series of Bonds.

         SECTION 2.4       Denominations.

         The Bonds of each Series shall be issuable only as registered Bonds in
the denominations prescribed by the terms of the Series Supplement creating the
particular Series.

         SECTION 2.5       Execution, Authentication, Delivery and Dating.

         The Bonds shall be executed on behalf of the Issuer by its Chairman,
President or one of its Vice Presidents. The signature of any of these officers
on the Bonds may be manual or facsimile.

         Bonds bearing the manual or facsimile signature of individuals who were
at any time the proper officers of the Issuer shall bind the Issuer,
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
such offices at the date of such Bonds.

         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, type written, mimeographed or otherwise
produced, in any authorized denomination, substantially of the




                                      -36-

<PAGE>   47




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.

         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.





                                      -37-

<PAGE>   48




         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.

         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




                                      -38-

<PAGE>   49




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 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 in the manner provided for in the related Series Supplement. 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 subsec tion (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




                                      -39-

<PAGE>   50




         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 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




                                      -40-

<PAGE>   51




         provided for when and as due and payable (any Bond on which such an
         amount due and pay able 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 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




                                      -41-

<PAGE>   52




         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 the
         following items (unless otherwise specified in the related Series
         Supplement):

                             (i) the Debt Service Requirement with respect to
                  such Series for the following Payment Date;

                            (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

         any Residual Bonds of any Series may be transferred directly or
         indirectly to (i) a Disqualified Organization or 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

         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 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




                                      -53-
<PAGE>   64




         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 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





                                      -54-

         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).

                                   ARTICLE III

                                    COVENANTS

         SECTION 3.1       Payment of Bonds.

         The Issuer will pay or cause to be duly and punctually paid the
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:

                  (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





                                      -57-
<PAGE>   68




         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 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,





                                      -58-
<PAGE>   69

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.

         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,





                                      -59-
<PAGE>   70





                  (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, 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 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 juris diction
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





                                      -60-
<PAGE>   71




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 por tion 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 662/3% of the Aggregate Current Principal
         Amount of the Bonds of each Series then Outstanding;

                  (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;






                                      -61-
<PAGE>   72




                  (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,

         respect to any Series under this Indenture, except as may be expressly
         permitted hereby or by any Series 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.

<PAGE>   73




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

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.

                           by the Trustee in the name, and at the 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,
                  the Issuer has delivered to the Trustee a Non-Disqualification

                  interest that will have accrued on such Series of Bonds (under
                  the Maximum Bond Interest Rate Assumption if such Series of
                  Bonds includes a Class or Classes of Variable Rate Bonds);

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 as
such hereunder shall, at the expense of the Issuer, execute and deliver all such
instruments as may be necessary to acknowledge the satisfaction and discharge of
this Indenture and the related Series Supplement with respect to such Series and

property held by it as part of the Trust Estate or other assets for such Series
remaining after satisfaction of the conditions specified in clauses (1) and (2)

the Trust Estate and any other assets specified in such election and securing
the Bonds as one or more REMICs has not been made and will not be made, to the
Issuer or upon Issuer Order or (y) with respect to each Series of Bonds for
which such an election has been made or will be made, and upon receipt by the
Trustee of a Non- Disqualification Opinion as required by Section 4.3, as
provided in the related Series Supplement.

         In the absence of an Issuer Request authorized by a Board Resolution,
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.

Paying Agent, as the Trustee may determine, to the Persons entitled thereto, of
the principal and interest for whose payment such money has been deposited 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

                  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);

                           (xii) ensure that all federal, state or local income
                  tax or information returns shall be signed by the 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





                                      -67-

                          (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.

         property or the making by the Issuer of an assignment for the benefit
         of creditors or the failure by the Issuer generally to pay its debts as

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 recourse

securing the related Series, in the event of (a) a failure by any Holder of a
Bond of any Series to recover by the Stated Maturity thereof or at all 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

         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 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 662/3% 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 662/3% 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 or caused to be delivered to the
         Trustee a Non-Disqual ification 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.

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 conse quences 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 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.

         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.

                  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,

         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
         662/3% 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

                  (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.

         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:




                                      -76-
<PAGE>   87




                  (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.

                  (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 662/3% 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




                                      -77-
<PAGE>   88




         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 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 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 connec tion 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





                                      -80-
<PAGE>   91

         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 Inden ture.

                  (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 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.

<PAGE>   93
                  (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.





                                      -83-
<PAGE>   94




                  (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 oth erwise 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);






                                      -84-
<PAGE>   95


                           (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 (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




                                      -85-
<PAGE>   96

         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 of any Series that
         the Trustee disqualify itself from acting as such with respect to one
         or more applicable Series of Bonds.

<PAGE>   97




         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,

         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,




                                      -87-
<PAGE>   98

         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 or shall cause to be given 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.

                  (f) Except as otherwise provided in the Series Supplement with
         respect to a Series, any costs or expenses incurred in connection with
         the resignation or removal of the Trustee with respect to such Series
         shall be paid by the Trustee.

         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 resigna tion 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 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




                                      -88-
<PAGE>   99

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 con firming 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, 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 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





                                      -90-
<PAGE>   101


         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.

         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.

                  (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),





                                      -93-

         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 fif teen 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
other provisions of TIA Section 314(a).

                                  ARTICLE VIII

           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 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




                                      -95-
<PAGE>   106




         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 Pay ment 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





                                      -96-
<PAGE>   107




         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 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,






                                      -97-
<PAGE>   108




                           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);

                           (iii) the Issuer shall have delivered to the 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)
                  and all conditions precedent to such release specified in this
                  subsection (d) have been satisfied.

         SECTION 8.4  Reserved.

         SECTION 8.5  Reserved.

         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




                                      -98-

         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 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




                                      -99-
<PAGE>   110
         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 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



                                     -100-

         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.

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

         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.

                  requirements, if any, set forth in the related Series
                  Supplement, (B) that all conditions to such release specified
                  in this subsection (a) and in the related Series Supplement
                  have been satisfied and (C) of the opinion required by Section

                             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;

                  (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;





                                     -106-
<PAGE>   117


                  (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 pro visions 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 assets
         specified in such election and securing the 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




                                     -107-
<PAGE>   118

         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 two-thirds 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 con sequences provided for in this Indenture;

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

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





                                     -108-
<PAGE>   119
                  (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 662/3% 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.

         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




                                     -109-
<PAGE>   120
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 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




                                     -110-
<PAGE>   121

         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




                                     -112-
<PAGE>   123


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.

                  (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 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




                                     -114-
<PAGE>   125

         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


                                     -115-
<PAGE>   126

Section 10.4. If not so withdrawn, the redemption request will be irre- vocable
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.

         SECTION 10.7 Reserved.

                                  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 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.




                                     -117-
<PAGE>   128


         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 state ment 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 embod ied 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



                                     -118-
<PAGE>   129

         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 Bond holders 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

                  (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
for convenience only and shall not affect the construction hereof.

         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 PER FORMED 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 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,

         Series 1998-1 Supplement dated as of March 31, 1998, between CMC
SECURITIES CORPORATION III, 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 bank (together
with its successors in trust thereunder as provided in the Indenture, the
"Trustee"), as trustee under an Indenture dated as of March 1, 1998 (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 $593,796,659 to be known as its
Collateralized Mortgage Obligations, Series 1998-1 (the "Series 1998-1 Bonds",
with references herein to "Bonds" being references solely to the Series 1998-1
Bonds)), and the Issuer and the Trustee are executing and delivering this
Series 1998-1 Supplement in order to provide for the Series 1998-1 Bonds.  All
terms used in this Series 1998-1 Supplement that are defined in the Indenture,
either directly or by reference therein, have the meanings assigned to them
therein as supplemented by Section 1 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 1998-1 Supplement, relate to
the Series 1998-1 Bonds, whether or not expressly so stated herein.


                                GRANTING CLAUSES

         The Issuer hereby Grants to the Trustee, for the exclusive benefit of
the Holders of the Series 1998-1 Bonds, all of the Issuer's right, title and
interest in and to (a) the mortgage pass-through certificates listed in
Schedule A to this Series 1998-1 Supplement, which the Issuer has caused to be
delivered to the Trustee herewith and which Conventional Certificates evidence
interests in pools of mortgage loans on one- to four-family residential
properties and individual condominium units, and all Distributions with respect
thereto payable at any time on or after the first Distribution Date, (b) each
Pledged Account for the Series 1998-1 Bonds, including all income from the
investment of funds in each such Pledged Account, (c) the Initial Deposit and
(c) all proceeds of the conversion, voluntary or involuntary, of any of the
foregoing into cash or other liquid property.  Such Grants are made, however,
in trust, to secure the Series 1998-1 Bonds, equally and ratably, without
prejudice or distinction between any Series 1998-1 Bond and any other Series
1998-1 Bond by reason of difference in time of issuance or otherwise, and to
secure (i) the payment of all amounts due on the Series 1998-1 Bonds as such
amounts become due in accordance with their terms, (ii) the payment of all
other sums payable under the Indenture or this Series 1998-1 Supplement with
respect to the Series 1998-1 Bonds, and (iii) compliance with the provisions of
the Indenture and this Series 1998-1 Supplement with respect to the Series
1998-1 Bonds, all as provided in the Indenture and this Series 1998-1
Supplement.

         The Trustee acknowledges such Grants, accepts the trusts hereunder in
accordance with the provisions hereof and of the Indenture, and agrees to
perform the duties herein or therein required in accordance with Article VI of
the Indenture.

SECTION 1.       Certain Defined Terms.

         Sections 1.1 and 2.3 of the Indenture provide that the meaning of
certain defined terms used in the Indenture shall, when applied to the Bonds of
a particular Series, be as defined in said Section 1.1 but with such additional
provisions as are specified in the related Series Supplement.  With respect to
the Series 1998-1 Bonds, the following provisions shall govern the defined
terms set forth below:

         "Accrual Date":  With respect to all Classes of Bonds which pay
interest, March 1, 1998.

         "Accrued Bond Interest":  For any interest-bearing Class of Bonds for
any Payment Date, the interest accrued during the related Interest Accrual
Period at the applicable Bond Interest Rate on the Class Current Principal
Balance (or in the case of a Class of Interest Only Bonds, the Class Notional
Balance) of such Class immediately prior to such Payment Date, calculated on
the basis of a 360-day year consisting of twelve 30-day months, less (i) in the
case of an interest-bearing Class of Senior Bonds, such Class's share of any
Net Interest Shortfall and the interest portion of any Excess Special Hazard
Losses and, after the applicable Cross-Over Date, the interest portion of any
Realized Losses applicable to its related Mortgage Loan Group and (ii) in the
case of a Class of Subordinate Bonds, such Class's share of any Net Interest
Shortfall and the interest portion of any Realized Losses applicable to its
related Mortgage Loan Group.  No Accrued Bond Interest will be payable with
respect to any Class of Bonds after the Payment Date on which the Class Current
Principal Balance or Class Notional Balance of such Class has been reduced to
zero.

         "Adjustment Amount":  For each anniversary of the Cut-off Date, for
each Mortgage Loan Group, the amount, if any, by which the applicable Special
Hazard Loss Amount (without giving effect to the deduction of the Adjustment
Amount for such anniversary) exceeds the lesser of (A) an amount calculated by
the Certificate Trustee and approved by each of the Rating Agencies, which
amount shall not be less than $500,000, and (B) the greater of (x) 1.0% (or if
greater than 1.0%, the highest percentage of Mortgage Loans of the applicable
Mortgage Loan Group by principal balance secured by Mortgaged Properties in any
five-digit California ZIP code area) of the outstanding principal balance of
all the Mortgage Loans of the applicable Mortgage Loan Group on the
Distribution Date immediately preceding such anniversary and (y) twice the
outstanding principal balance of the Mortgage Loan of the applicable Mortgage
Loan Group which has the largest outstanding principal balance on the
Distribution Date immediately preceding such anniversary.

         "Allocable Share":  With respect to any Class of Subordinate Bonds of
any Bond Group:

                 (a)      as to any Payment Date and amounts payable pursuant
         to clauses (i), (iv) and (vi) of the applicable Subordinate Optimal
         Principal Amount for such Bond Group, the fraction, expressed as a
         percentage, the numerator of which is the Class Current Principal
         Balance of such Class and the denominator of which is the aggregate of
         the Class Current Principal Balances of all Classes of the Subordinate
         Bonds of such Bond Group; and

                 (b)      as to any Payment Date and amounts distributable
         pursuant to clauses (ii), (iii) and (v) of the applicable Subordinate
         Optimal Principal Amount for such Bond Group, and as to each Class of
         Subordinate Bonds of such Bond Group (other than the Class of
         Subordinate Bonds of such Bond Group having the lowest numerical
         designation as to which the Class Prepayment Distribution Trigger
         shall not be applicable) for which (x) the related Class Prepayment
         Distribution Trigger has been satisfied on such Distribution Date, the
         fraction, expressed as a percentage, the numerator of which is the
         Class Current Principal Balance of such Class and the denominator of
         which is the aggregate of the Class Current Principal Balances of all
         Classes of Subordinate Bonds of such Bond Group and (y) the related
         Class Prepayment Distribution Trigger has not been satisfied on such
         Payment Date, 0%; provided that if on a Payment Date, the Class
         Current Principal Balance of any Class of Subordinate Bonds of such
         Bond Group for which the related Class Prepayment Distribution Trigger
         was satisfied on such Payment Date is reduced to zero, any amounts
         paid pursuant to this clause (b), to the extent of such Class's
         remaining Allocable Share, shall be paid to the remaining Classes of

                 (ii)     LIBOR will be established by the Trustee on each
         LIBOR Determination Date as follows:

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

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

                          (c)     If on the first LIBOR Determination Date, the
                 Trustee is required but is unable to determine the Reserve
                 Interest Rate in the manner provided in paragraph (b) above,
                 LIBOR shall be 5.6875%.  If on any subsequent LIBOR
                 Determination Date, the Trustee is required but is unable to
                 determine the Reserve Interest Rate in the manner provided in
                 paragraph (b) above, LIBOR shall be LIBOR for the immediately
                 preceding LIBOR Determination Date.

         fourth, the Component P Deferred Amount for Component P-2 for such
         Payment Date, to the Class P Bonds; provided that (i) on any Payment
         Date, payments pursuant to this priority fourth shall not exceed the
         excess, if any, of (x) the Group 2 Available Funds remaining after
         giving effect to payments pursuant to clauses first through third
         above over (y) the sum of the amount of Accrued Bond Interest for such
         Payment Date and Accrued Bond Interest remaining unpaid from previous
         Payment Dates on all Classes of Group 2 Subordinate Bonds then
         outstanding, (ii) such payments shall not reduce the Component Current
         Principal Balance of Component P-2 and (iii) no payment shall be made

         (B)     If, after payments have been made pursuant to priorities first
and second of this Section 10(a)(iii) on any Payment Date, the remaining Group
2 Available Funds are less than the sum of the Group 2 Senior P&I Optimal
Principal Amount and the Component P Principal Payment Amount for Component P-2
for such Payment Date, such amounts shall be proportionately reduced, and such
remaining Group 2 Available Funds shall be paid on the Group 2 Senior Bonds
(other than the Class 2-X Bonds) on the basis of such reduced amounts.
Notwithstanding any reduction in principal payable to the Class P Bonds
pursuant to this paragraph, the Component Current Principal Balance of
Component P-2 shall be reduced not only by principal so paid but also by the
difference between (i) principal payable to the Class P Bonds with respect to
Component P-2 in accordance with clause (b) of priority third above and (ii)
principal actually paid to the Class P Bonds with respect to Component P-2
after giving effect to this paragraph (such difference, the "Component P-2 Cash
Shortfall" with respect to such Payment Date).  The Component P-2 Cash
Shortfall with respect to any Payment Date shall be added to the Component P
Deferred Amount applicable to Component P-2.

         (iv)    Group 2 Subordinate Bonds.  On each Payment Date prior to the
acceleration, if any, of the Bonds, the Group 2 Available Funds remaining after
the payments made pursuant to Section 10(a)(iii) shall be paid to the Group 2
Subordinate Bonds sequentially, in the following order, to the Class 2-B-1,
Class 2-B-2, Class 2-B-3, Class 2-B-4, Class 2-B-5 and Class 2-B-6 Bonds, in
each case up to an amount equal to and in the following order: (a) the Accrued

thereon remaining unpaid from previous Payment Dates and (c) such Class's
Allocable Share for such Payment Date.

         (v)     Group 3 Senior Bonds.  On each Payment Date prior to the

         second, to the interest-bearing Classes of Group 3 Senior Bonds, any
         Accrued Bond Interest thereon remaining unpaid from previous Payment
         Dates, to the extent of remaining Group 3 Available Funds, with any
         shortfalls in available amounts being allocated between such Classes
         in proportion to the amount of Accrued Bond Interest remaining unpaid
         for each such Class for such Payment Date;

         third, the Group 3 Senior P&I Optimal Principal Amount for such
         Payment Date in the following order of priority:  (a) to the Class R-3

         Component P-3, pro rata, until the Class Current Principal Balance and
         the Component Current Principal Balance thereof, respectively, have
         been reduced to zero.

         (vi)    Group 3 Subordinate Bonds.  On each Payment Date prior to the
acceleration, if any, of the Bonds, the Group 3 Available Funds remaining after
the payments made pursuant to Section 10(a)(v) shall be paid among the Group 3
Subordinate Bonds sequentially, in the following order, to the Class 3-B-1,
Class 3-B-2, Class 3-B-3, Class 3-B-4, Class 3-B-5 and Class 3-B-6 Bonds, in
each case up to an amount equal to and in the following order: (a) the Accrued
Bond Interest thereon for such Payment Date, (b) any Accrued Bond Interest
thereon remaining unpaid from previous Payment Dates and (c) such Class's
Allocable Share for such Payment Date.

         (b)     On each Payment Date, any Available Funds remaining in the

         (d)     On each Payment Date, the Trustee shall pay to the Holders of
the Class R-2 and Class R-3 Bonds as contingent interest any remaining amounts
in REMIC II and REMIC III, respectively, after all amounts otherwise required
to be paid have been so paid, which remaining amounts shall not reduce the
Class Current  Principal Balances of the Class R-2 and Class R-3 Bonds.

         (e)     Payment of the above amounts to each Bondholder shall be made
(i) by check mailed to each Bondholder entitled thereto at the address

the principal portion of any Realized Loss shall be made on any Payment Date to
(A) any Class of Group 1 Bonds or Component P-1 to the extent that such
allocation would result in the reduction of the aggregate of the Class Current

Class of Bonds or the Component Current Principal Balance of the related P
Component on the related Payment Date in accordance with Subsection 12(c).

         (c)     All allocations of the principal portion of Realized Losses in

Payment Date, except that the aggregate amount of the principal portion of
Realized Losses to be allocated to Component P-1 or Component P-2 on any

Subordinate Bond Writedown Amount or Group 3 Subordinate Bond Writedown Amount,
respectively, shall effect a corresponding reduction in the Class Current
Principal Balance of (i) if prior to the Group 1 Cross-Over Date, the Group 2
Cross-Over Date or Group 3 Cross-Over Date, as applicable, the Current
Principal Balances of the Group 1 Subordinate Bonds, the Group 2 Subordinate
Bonds and the Group 3 Subordinate Bonds, respectively, in the reverse order of
their numerical Class designations and (ii) from and after the Group 1
Cross-Over Date, the Group 2 Cross-Over Date or Group 3 Cross-Over Date, as
applicable, the Group 1 Senior Bonds (excluding Component P-1), the Group 2
Senior Bonds (excluding Component P-2) and the Group 3 Senior Bonds,
respectively, pro rata, which reduction shall occur on such Payment Date after
giving effect to payments made on such Payment Date.

         (e)     On each Payment Date, on or prior to the Group 1 Cross-Over
Date, the Indenture Trustee shall determine the Component P Deferred Payment
Writedown Amount, if any, for each of Component P-1 and Component P-2 for such
Payment Date.  Any such Component P Deferred Payment Writedown Amount shall
effect a corresponding reduction in the Class Current Principal Balance of the
Subordinate Bonds of the applicable Bond Group, in the reverse order of their
numerical Class designations.

         (f)     Net Interest Shortfalls shall be allocated among the Classes
of Bonds in a Bond Group in proportion to the amount of Accrued Bond Interest
that would have been allocated thereto in the absence of such shortfalls.  The
interest portion of Realized Losses in a Mortgage Loan Group shall be allocated
first to the Classes of Subordinate Bonds in the related Bond Group in reverse
order of their numerical designations and, following the applicable Cross- Over
Date, such Realized  Losses will be allocated to the Classes of
interest-bearing Senior Bonds in the related Bond Group in proportion to the
amount of Accrued Bond Interest that would have been allocated thereto in the
absence of such Realized Losses.

         (g)     Any Realized Loss allocated to a Class or Component P shall be
allocated to the Corresponding Class of REMIC I Interest and the Corresponding
Class of REMIC II Interest.

1% of the aggregate of the Scheduled Principal Balances of the Mortgage Loans
in all of the Mortgage Loan Groups, the amount by which the amount referred to
in clause (A) exceeds the amount referred to in clause (B) shall be deducted
from the remaining amount of the Initial Deposit and paid to the Holder of the

Agreement requires the consent of the holder of the Conventional Certificates,
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

                 (1)       reduce the amount of, or delay the timing of,
                           payments received on its related Trust Fund that are
                           required to be distributed on any Conventional
                           Certificate or change the repurchase price with
                           respect thereto, change any place of payment where,
                           or the coin or currency in which, any Conventional
                           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 Conventional
                           Certificate or adversely affect the tax consequences
                           to any holder of a Conventional Certificate;

                 (2)       change the requirement of the consent of the holders
                           of the Conventional 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

                 (4)       permit the creation of any lien ranking prior to or
                           on a parity with the related Trust created by the
                           Pooling and Servicing Agreement with respect to any
                           part of its related Trust Fund or terminate the
                           related Trust created by the Pooling and Servicing
                           Agreement on any property at any time subject thereto
                           or deprive the Holder of any Bond of the security
                           afforded by the Conventional 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 1998-1 Bonds, consent to the release from or termination of a Trust
created by the Pooling and Servicing Agreement with respect to any





                                     - 40 -
<PAGE>   44
Mortgage Loan when such action by the Issuer and the Trustee is specifically
authorized by any other provision of the Indenture, this Series 1998-1
Supplement or the Pooling and Servicing Agreement.

         The Trustee may in its discretion determine whether or not any Series
1998-1 Bonds would be affected by any proposed action and any such
determination shall be conclusive upon the Holders of all Series 1998-1 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 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 1998-1 Bonds 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 Conventional 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 1998-1 Bonds.

SECTION 18.      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 REMIC
I, REMIC II and REMIC III 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
Bonds are issued.  For the purposes of the REMIC elections in respect of the
Trust Estate, each Class of Bonds having no Components (other than the Class
R-1, Class R-2 and Class R-3 Bonds), and each Component shall be designated as
the "regular interests" and the Class R-3 Bonds shall be designated as the sole
class of "residual interest" in REMIC III.  The REMIC I Interests shall be
designated as "regular interests" and the Class R-1 Bonds shall be designated
as the sole class of "residual interest" in REMIC I.  The REMIC II Interests
shall be designated as "regular interests" and the Class R-2 Bonds shall be
designated as the sole class of "residual interest" in REMIC II.  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 REMIC I Interests, REMIC II Interests and the Bonds (including the
Components).

         (b)     The Closing Date is hereby designated as the "startup day" of
each of REMIC I, REMIC II and REMIC III within the meaning of Section
860G(a)(9) of the Code.

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

Bonds shall be the tax matters person of REMIC I, the Holder of the Class R-2
Bonds shall be the tax matters person of REMIC II and the Holder of the Class

in relation to any tax matter or controversy involving REMIC I, REMIC II or
REMIC III and (ii) represent REMIC I, REMIC II or REMIC III in any

attorney-in-fact for purposes of signing any tax returns required to be filed
on behalf of the REMICs.

         (d)     The Trustee shall prepare or cause to be prepared, sign and
file all of the tax returns in respect of each Series REMIC, other than tax
returns required to be filed by a Master Servicer pursuant to 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 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.

such compliance guidance, the Trustee shall provide (i) to any Transferor of a
Class R-1, Class R-2 or a Class R-3 Bond such information as is necessary for
the application of any tax relating to the transfer of a Class R-1, Class R-2
or a Class R-3 Bond to any Person who is not a Permitted Transferee, (ii) to
Bondholders such information or reports as are required by the Code or the
REMIC Provisions including reports relating to interest, original issue

(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.
The Prepayment Assumption for the purposes of Section 4.3(b)(iv) of the
Indenture is the Prepayment Assumption as defined in Section 1 hereof.

Estate created hereunder to take such action as shall be necessary to create or
maintain the status of each Series REMIC as a REMIC under the REMIC Provisions.

<PAGE>   46
that, under the REMIC Provisions, if taken or not taken, as the case may be,
could (i) endanger the status of any of the Series REMICs as a REMIC or (ii)
result in the imposition of a tax upon the Trust Estate (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) (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 any of the Series REMICs created hereunder, endanger such status or
result in the imposition of such a tax.  The Trustee shall cause the Master
Servicers not to take or fail to take any action (whether or not authorized
hereunder) as to which the Trustee 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 (other than the Initial Deposit) to not consist of
"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)     In the event that any tax is imposed on a "prohibited
transaction" of any of the Series REMICS created hereunder as defined in
Section 860F(a)(2) of the Code, on "net income from foreclosure property" of
any of the Series REMICs as defined in Section 860G(c) of the Code, on any
contributions to any of the Series REMICs 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(m) hereof, if such tax arises
out of or results from a breach by the Trustee of any of its obligations
hereunder, (ii) to the applicable Master Servicer pursuant to the Pooling and
Servicing Agreement, if such tax arises out of or results from a breach by such
Master Servicer of any of its obligations under the Pooling and Servicing
Agreement, or otherwise (iii) from the applicable Group Available Funds.

         (h)     On or before April 15 of each calendar year, commencing April
15, 1999, the Trustee shall deliver to each Master Servicer and each Rating
Agency a certificate from a Responsible Officer of the Trustee stating the
Trustee's compliance with this Section 18.

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

         (j)     The Trustee shall not permit the acquisition of any assets by
any of the Series REMICs 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 such Series REMICs will not cause
any of the Series REMICs to fail to qualify as a REMIC at any time that any
Bonds are outstanding or subject any of the Series REMICs 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 any
of the Series REMICs will receive a fee or other compensation for services nor
permit 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.

of the Treasury Regulations, the "latest possible maturity date" of each
regular interest in REMIC I, REMIC II and REMIC III would be reduced to zero is
the Payment Date occurring in May 2028.

         (m)     The Trustee agrees to indemnify the Trust Estate, the Issuer
and the Master Servicers 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 Servicers, as a result of a breach of the Trustee's
covenants set forth in Section 18 hereof.

         (n)     The REMIC I Interests shall be issued as non-certificated
interests.  The Trustee shall be the sole holder of the REMIC I Interests,
which shall not be transferable under any circumstances.  The Class R-1 Bonds
shall be issued in fully registered certificated form and shall be executed and
authenticated as provided herein.  Principal of and interest on the REMIC I

         the excess, if any, of (a) the Net Rates on each Group 1 Mortgage Loan
         over (b) 6.75% per annum, and in the case of the Class II-2-X REMIC II

SECTION 19.      Form of Series 1998-1 Bonds; Matters Relating to Book Entry
                 Bonds.

         (a)     The Series 1998-1 Bonds shall be in the respective forms
attached hereto as Exhibits A-1 through A-8.  If the Series 1998-1 Bonds are
listed on any stock exchange at any time after the Closing Date, then the
Issuer shall, if required as a condition to such listing, prepare and deliver
to the Trustee Series 1998-1 Bonds in substantially the same form as the Series
1998-1 Bonds issued on the Closing Date, but with such other additional
features and such modifications, if any, as shall be deemed by the Issuer to be
necessary or appropriate in order to comply with the requirements of such stock
exchange for the listing of the Series 1998-1 Bonds on such exchange.  Series
1998-1 Bonds in the form issued on the Closing Date shall thereafter be
exchangeable for Series 1998-1 Bonds in such revised form to the same extent as
temporary Bonds are exchangeable for definitive Bonds pursuant to Section 2.6
of the Indenture.  The Issuer shall also include in the Series 1998-1 Bonds of
any Class any information required to be set forth therein pursuant to the Code
and applicable regulations thereunder.

         (b)     The Clearing Agency, the Issuer and the Trustee have entered
or will enter into the Letter Agreements.  Each Class of Book Entry Bonds will
be issued and registered in the form of a single typewritten bond certificate
to be delivered to the Clearing Agency by the Issuer substantially in the
respective forms for each such Class of Bonds attached as exhibits hereto.
Such Bond certificates for each such Class of Bonds shall be initially
registered on the Bond Register in the name of the nominee of such Clearing
Agency and no Beneficial Owner will receive a certificate representing its
interests in any Class of Book Entry Bonds except in the case of Individual
Bond Certificates as provided herein and except in the event that the Trustee
issues Definitive Bonds, as provided in Section 2.14 of the Indenture.

         (c)     Prior to Book Entry Termination, except for Individual Bond
Certificates, each Bond other than the Residual Bonds will remain registered in
the name of the Clearing Agency or its nominee and at all times: (i)
registration of such Bonds may not be transferred by the Trustee or the Bond
Registrar except to another Clearing Agency; (ii) ownership and transfers of
registration of such Bonds on the books of the Clearing Agency shall be
governed by applicable rules established by the Clearing Agency; (iii) the
Clearing Agency may collect its usual and customary fees, charges and expenses
from its Clearing Agency Participants; (iv) the Trustee shall deal with the
Clearing Agency, Clearing Agency Participants and indirect participating firms
as representatives of the Beneficial Owners of the Book Entry Bonds for
purposes of exercising the rights of Holders under the Indenture, and requests
and directions for and votes of such representatives shall not be deemed to be
inconsistent if they are made with respect to different Beneficial Owners; and
(v) the Trustee may rely and shall be fully protected in relying upon
information furnished by the Clearing Agency with respect to its Clearing
Agency Participants and furnished by the Clearing Agency Participants with
respect to indirect participating firms and their direct or indirect Beneficial
Owners.

         (d)     After Book Entry Termination, Definitive Bonds shall, after
execution and delivery of a supplemental indenture containing any provisions,
which in the opinion of the Issuer are necessary for such purpose, be issued to
the Beneficial Owners of Book Entry Bonds outstanding at the time of such Book
Entry Termination and such Bonds shall no longer be "Book Entry Bonds."

SECTION 20.      The Master Servicers and the Trustee.

         The Master Servicers, pursuant to the Pooling and Servicing Agreement,
will provide the Certificate Trustee who will provide the Trustee with certain
information concerning the Mortgage Loans underlying the Conventional
Certificates.  The Trustee shall not be required to recompute, verify or
recalculate the information supplied to it by the Issuer or any 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.

SECTION 21.      Supplements, Modifications and Ratifications of Indenture.

         (a)     The Trustee will be required to mail, in each year when
required by the TIA, to all Bondholders a brief report relating to its
eligibility and qualifications to continue as the Trustee under the Indenture,

maturity date of certain indebtedness owing by the Issuer to it in the
Trustee's commercial capacity, the property and funds physically held by the
Trustee as such, any release or substitution of property subject to the lien of
the Indenture which has not been previously reported, any additional Series of
Bonds not previously reported and any action taken by the Trustee which
materially affects the Series 1998-1 Bonds and which has not been previously
reported.

         (b)     Any references in the Indenture to "the Trust Estate securing
a Series as a REMIC" are hereby deemed to refer to "each Series REMIC as
REMIC".

         (c)     References to "Residual Interest Holders" in the Indenture are
hereby deemed to refer to the Holders of the Class R-1, Class R-2 and Class R-3
Bonds with respect to the related Series REMIC.

         (d)     For purposes of clause (y) of the first paragraph of Section
4.1 of the Indenture, the final distribution of assets in each Series REMIC
after all Bonds have received all required principal and interest payments
shall be made as follows: (i) in the case of an optional redemption pursuant to
Section 16 of this Series 1998-1 Supplement with respect to the REMIC I, to the
purchaser of the Mortgage Loans of the related Mortgage Loan Group, and with
respect to REMIC II, to the Class R-2 Bonds, and with respect to REMIC III, to
the Class R-3 Bonds and (ii) in all other cases to the Class R-1, Class R-2 and
Class R-3 Bonds pursuant to this Series 1998-1 Supplement.

         (e)     For purposes of Section 5. 8 of the Indenture, Clause Second
(b), interest shall be paid to the twenty- fifth day before the date fixed for
payment in Section 5.8 in the case of all Classes of Bonds (other than the
Class P Bonds).

         (f)     For purposes of Section 5.8 of the Indenture, Clause Fifth,
subclause (ii), the remaining assets included in each Series REMIC shall be
paid to the Class R-1, Class R-2 and Class R-3 Bonds to the extent such assets
remain in the REMIC I, REMIC II or REMIC III, respectively.

         (g)     For purposes of Section 8.2(d) of the Indenture, assets
released from the Indenture pursuant to such Section and payable to the
Residual Interest shall be paid to the Class R-1, Class

         (h)     Section 1.1 of the Indenture is hereby amended to restate
subsection (x) of the definition of "Eligible Investments" as follows:

                 (x)      any other demand, money market or time deposit
         obligation, security or investment which is acceptable to each of the
         Rating Agencies as confirmed in writing by each such Rating Agency.

         (i)     The Indenture as modified and supplemented by this Series
1998-1 Supplement with respect to the Series 1998-1 Bonds (but which
modification and supplement shall not apply to any other Series of Bonds unless

ratified and confirmed, and the Indenture as so modified and supplemented by
this Series 1998-1 Supplement shall be read, taken and construed as one and the
same instrument.

         (j)     Any references in the Indenture to "Administrator" are hereby
deemed to refer to the applicable Master Servicer under the Pooling and
Servicing Agreement.  Any references to the "Pooling and Administration
Agreement" in the Indenture are hereby deemed to refer to the "Pooling and

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 6.7 of

compensated and reimbursed for its expenses pursuant to the provisions of the
Pooling and Servicing Agreement." Section 8.9 of the Indenture shall not apply.

         (k)     For purposes of determining whether an "Event of Default"
under the Indenture has occurred, the Stated Maturity Date of each Class of
Bonds shall be deemed to be the Payment Date occurring in May 2028.

         (l)     In lieu of delivering reports to Bondholders pursuant to
Section 8.7 of the Indenture, the Trustee shall deliver the reports pursuant to
Section 10(f) hereof.

SECTION 22.      Certain Matters Regarding Registration of Transfer and
                 Exchange of Bonds.

         (a)     Subject to Section 19(b) and upon the satisfaction of the
applicable conditions set forth below, upon surrender for registration of
transfer of any Bond at any office or agency of the Trustee maintained for such
purpose, the Trustee shall sign, countersign and shall deliver, in the name of
the designated transferee or transferees, a new Bond of a like Class and
aggregate Current Principal Balance or Class Notional Balance, as applicable,
but bearing a different number.

         (b)     By acceptance of an Individual Bond Certificate, each holder
of such an Individual Bond Certificate acknowledges the restrictions on the
transfer of such Bond set forth in the applicable legends on the face thereof
and agrees that it will transfer such a Bond only as provided herein.  Section
2.15(b) of the Indenture shall not apply with respect to transfers of
Individual Bond Certificates.  In addition to the provisions of paragraph (f)
below, the following restrictions shall apply with respect to the transfer and
registration of transfer of an Individual Bond Certificate to a transferee that
takes delivery in the form of an Individual Bond Certificate:

                 (i)      In the event that a transfer of an Individual Bond
         Certificate is to be made under this Section 22(b)(i), (A) 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 the Securities
         Act and applicable state securities laws or is being made pursuant to
         such Securities Act and applicable state securities laws, which
         Opinion of Counsel shall not be an expense of the Trustee or the
         Issuer and (B) 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 or the Issuer. Any Holder of an
         Individual Bond Certificate 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.

                 (ii)     Transfers of Individual Bond Certificates may be made
         in accordance with this Section 22(b)(ii) if the prospective
         transferee of such Individual Bond Certificate provides the Trustee
         and the Issuer with a Rule 144A Certificate, which certificate shall
         not be an expense of the Trustee or the Issuer.  No transfer of any
         Individual Bond Certificates may be made pursuant to this Section
         22(b)(ii) by the Issuer.  Any Holder of an Individual Bond Certificate
         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.

         (c)     Subject to paragraph (f), so long as a Global Bond Certificate
of a Class of Other Subordinate Bonds is outstanding and is held by or on
behalf of the Clearing Agency, transfers of beneficial interests in such Global
Bond Certificate, or transfers by Holders of Individual Bond Certificates of
such Class to transferees that take delivery in the form of beneficial
interests in the





                                     - 51 -

applicable Global Bond Certificate, may be made only in accordance with this
paragraph (c) and in accordance with the rules of the Clearing Agency:

                 (i)      In the case of a beneficial interest in a Global Bond
         Certificate being transferred to an Institutional Accredited Investor,
         such transferee shall be required to take delivery in the form of an
         Individual Bond Certificate or Certificates and the Trustee shall
         register such transfer only upon compliance with the provisions of
         paragraph (b)(i).

                 (ii)     In the case of a beneficial interest in a Global Bond
         Certificate being transferred to a transferee that takes delivery in
         the form of one or more Individual Bond Certificates of the applicable
         Class, except as set forth in clause (i) above, the Trustee shall
         register such transfer only upon compliance with the provisions of
         paragraph (b)(ii).

                 (iii)    In the case of an Individual Bond Certificate being
         transferred to a transferee that takes delivery in the form of a
         beneficial interest in the Global Bond Certificate of the applicable
         Class, the Trustee shall register such transfer if the transferee has
         provided the Trustee with a Rule 144A Certificate or comparable
         evidence as to its QIB status.

                 (iv)     No restrictions shall apply with respect to the
         transfer or registration of transfer of a beneficial interest in the
         Global Bond Certificate of a Class to a transferee that takes delivery
         in the form of a beneficial interest in the Global Bond Certificate of
         such Class; provided that each such transferee shall be deemed to have
         made such representations and warranties contained in the Rule 144A
         Certificate as are sufficient to establish that it is a QIB.

         (d)     Subject to paragraph (f) below, an exchange of a beneficial
interest in a Global Bond Certificate of a Class for one or more Individual
Bond Certificates of such Class, an exchange of one or more Individual Bond
Certificates of a Class for a beneficial interest in the Global Bond
Certificate of such Class and an exchange of one or more Individual Bond
Certificates of a Class for one or more other Individual Bond Certificates of
such Class (in each case, whether or not such exchange is made in anticipation
of subsequent transfer, and, in the case of the Global Bond Certificate of such
Class, so long as such Bond is outstanding and is held by or on behalf of the
Clearing Agency) may be made only in accordance with this paragraph (d) and in
accordance with the rules of the Clearing Agency:

                 (i)      A holder of a beneficial interest in a Global Bond
         Certificate of a Class may at any time exchange such beneficial
         interest for an Individual Bond Certificates of such Class.

                 (ii)     A holder of one or more Individual Bond Certificates
         of a Class may exchange such Individual Bond Certificate or Individual
         Bond Certificates for a beneficial interest in the Global Bond
         Certificate of such Class if such holder furnishes to the Trustee a
         Rule 144A Certificate or comparable evidence as to its QIB status.

                 (iii)  A holder of an Individual Bond Certificate of a Class
         may exchange such Individual Bond Certificate for an equal aggregate
         principal amount of Individual Bond Certificates of such Class in
         different authorized denominations without any certification.

         (e)      (i)     Upon acceptance for exchange or transfer of an
         Individual Bond Certificate of a Class for a beneficial interest in a
         Global Bond Certificate of such Class as provided herein, the Trustee
         shall cancel such Individual Bond Certificate and shall (or shall
         request the Clearing Agency to) endorse on the schedule affixed to the
         applicable Global Bond Certificate (or on a continuation of such
         schedule affixed to the Global Bond Certificate and made a part
         thereof) or otherwise make in its books and records an appropriate
         notation evidencing the date of such exchange or transfer and an
         increase in the bond certificate balance of the Global Bond
         Certificate equal to the bond certificate balance of such Individual
         Bond Certificate exchanged or transferred therefor.

                 (ii)     Upon acceptance for exchange or transfer of a
         beneficial interest in a Global Bond Certificate of a Class for an
         Individual Certificate of such Class as provided herein, the Trustee
         shall (or shall request the Clearing Agency to) endorse on the
         schedule affixed to such Global Bond Certificate (or on a continuation
         of such schedule affixed to such Global Bond Certificate and made a
         part thereof) or otherwise make in its books and records an
         appropriate notation evidencing the date of such exchange or transfer
         and a decrease in the bond certificate balance of such Global Bond
         Certificate equal to the bond certificate balance of such Individual
         Bond Certificate issued in exchange therefor or upon transfer thereof.

         (f)     Subject to the restrictions on transfer and exchange set forth
in this Section 22, the Holder of any Individual Bond Certificate may transfer
or exchange the same in whole or in part (in an initial Current Principal

of $1.00 in excess thereof) by surrendering such Individual Bond Certificate to
the Trustee, together with an executed instrument of assignment and transfer
satisfactory in form and substance to the Trustee in the case of transfer and a
written request for exchange in the case of exchange.  The holder of a
beneficial interest in a Global Bond Certificate may, subject to the rules and
procedures of the Clearing Agency, cause the Clearing Agency (or its nominee)

beneficial interest for one or more Individual Bond Certificates.  Following a
proper request for transfer or exchange, the Trustee shall, within five

documentation, if any, required hereunder, sign, countersign and deliver to the
transferee (in the case of transfer) or holder (in the case of exchange) or
send by first class mail at the risk of the transferee (in the case of
transfer) or holder (in the case of exchange) to such address as the transferee
or holder, as applicable, may request, one or more Individual Bond
Certificates, as the case may require, for a like aggregate initial Current
Principal Balance and in such authorized denomination or denominations as may
be requested.  The presentation for transfer or exchange of any Individual Bond
Certificate shall not be valid unless made to the Trustee by the registered
holder in person, or by a duly authorized attorney-in-fact.

         (g)     The references in the Indenture to Exhibit D of this Series
1998-1 Supplement shall instead be to Exhibit C-1 or Exhibit C-3.

       CMC SECURITIES CORPORATION III, a corporation duly organized and
existing under the laws of the State of Delaware (herein referred to as the
"Issuer"), for value received hereby promises to pay to CEDE & CO. or
registered assigns, the principal sum of ____________ DOLLARS ($_____________)
in monthly payments of principal and interest on the twenty-fifth day of each
month or, if such day is not a Business Day, then the next succeeding Business
Day (each a "Payment Date"), commencing in April 1998 and ending on or before
the Payment Date occurring in ______________.  This Bond is one of a duly
authorized issue of non-recourse Bonds of the Issuer, designated as its
Collateralized Mortgage Obligations, Series 1998-1.  The Bonds are issued in
multiple classes under the Issuer's Indenture dated as of March 1, 1998, as
amended (herein called the "Indenture"), to which Indenture and all indentures
supplemental thereto, including the Series 1998-1 Supplement dated as of March
31, 1998 (the "Series 1998-1 Supplement"), between the Issuer and The First
National Bank of Chicago, as indenture trustee (the "Indenture Trustee", which
term includes any successor Trustee under the Indenture), which authorized the
Bonds, reference is hereby made for a statement of the respective
<PAGE>   62
rights thereunder of the Issuer, the Indenture Trustee and the holders of the
Bonds and the terms upon which the Bonds are, and are to be, authenticated and
delivered.

       The Bonds are collateralized by three separate series of mortgage pass-
through certificates (the "Conventional Certificates"), each of which series
evidences the entire beneficial ownership interest in one of three pools of
Mortgage Loans.  Each pool of Mortgage Loans has been deposited into a separate
trust (each, a "Trust") pursuant to the terms of the Pooling and Servicing
Agreement (the "Pooling and Servicing Agreement") dated as of March 1, 1998
among the Issuer, as depositor, Bank of America, FSB and Cendant Mortgage
Corporation, as master servicers (the "Master Servicers"), and The First
National Bank of Chicago, as certificate trustee (the "Certificate Trustee").
Each Trust has created a series of Conventional Certificates for the benefit of
the Issuer in exchange for the related pool of Mortgage Loans.  The
Conventional Certificates were pledged to the Indenture Trustee under the terms
of the Indenture.

       All capitalized terms used without definition in this Bond shall have
the meanings assigned to such terms in the Indenture or the Series 1998-1
Supplement, as applicable.

       This Bond does not purport to summarize the Indenture or the Series
1998-1 Supplement and reference should be made to the Indenture and the Series
1998-1 Supplement for the interests, rights and limitations of rights,
benefits, obligations and duties of the holders of the Bond thereunder, and the
rights, duties and immunities of the Indenture Trustee.

       Payments of principal of and interest on this Bond will be paid in
accordance with the terms of the Series 1998-1 Supplement and will be made out
of the Available Funds for such Payment Date, to the extent and subject to the
limitations set forth in the Series 1998-1 Supplement, on each Payment Date to
the Person in whose name this Bond is registered at the close of business on
the last Business Day of the month immediately preceding the month of such
distribution (the "Record Date").  All sums payable on this Bond are payable in
the coin or currency of the United States of America as at the time of payment
is legal tender for the payment of public and private debts.

       Realized Losses, Net Interest Shortfalls and certain writedown amounts
shall be allocated among the Classes of Bonds on the applicable Payment Date in
the manner set forth in the Series 1998-1 Supplement.  To the extent provided
in the Series 1998-1 Supplement, the Subordinate Bonds will be subordinated in
right of payment to the other Classes of Bonds and each Class of the
Subordinate Bonds will be subordinated in right of payment to each of the other
Classes of Subordinate Bonds with a lower numerical designation, if any.  All
Realized Losses, Net Interest Shortfalls and writedown amounts allocated to any
Class of Bonds will be allocated pro rata among the outstanding Bonds of such
Class, as described in the Series 1998-1 Supplement.

       The Bonds are limited in right of payment to certain collections and
recoveries respecting the Mortgage Loans and certain other assets, all as more
specifically set forth in the Series 1998-1 Supplement.

       So long as this Bond is registered in the name of a Depository or its
nominee, the Indenture Trustee will make payments of principal of and interest
on this Bond by wire transfers of immediately available funds to the Depository
or its nominee.  Otherwise, all payments on this Bond under the Series 1998-1
Supplement will be made by or on behalf of the Indenture Trustee as provided in
the Indenture.  Notwithstanding the above, the final payment on this Bond will
be made





                                      -2-
<PAGE>   63
after due notice by the Indenture Trustee of the pendency of such payment and
only upon presentation and surrender of this Bond at its principal Corporate
Trust Office or such other offices or agencies appointed by the Indenture
Trustee for that purpose and such other locations provided in the Series 1998-1
Supplement.

       The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Issuer and the rights of the Holders of the Bonds under the Indenture at any
time by the Issuer with the consent of the Holders of Bonds representing
two-thirds of the Aggregate Current Principal Amount of all Bonds at the time
Outstanding, in case Outstanding Bonds of all Series are to be affected, or
with the consent of the Holders of two-thirds of the Aggregate Current
Principal Amount of all the Bonds at the time Outstanding of each Series to be
affected, in case one or more, but less than all, of the Series of Bonds then
Outstanding are to be affected; provided however, that 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 of the Indenture 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 of
the Indenture 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
of the Indenture shall be made in respect of such Series of Bonds without the
consent of the Holders representing not less than two-thirds of the Aggregate
Current Principal Amount of the Highest Priority Junior Class of such Series.

       The Indenture also contains provisions permitting the Holders of Bonds
representing specified percentages of the Aggregate Current Principal Amount of
the Bonds of a Series at the time Outstanding on behalf of the Holders of all
the Bonds of such Series, to waive compliance by the Issuer with certain
provisions of the Indenture and certain past defaults under the Indenture and
their consequences.  Any such consent or waiver by the Holder, at the time of
the giving thereof, of this Bond (or any one or more Predecessor Bonds) shall
be conclusive and binding upon such Holder and upon all future holders of this
Bond and of any Bond issued upon the registration of transfer hereof or in
exchange herefor or in lieu hereof whether or not notation of such consent or
waiver is made upon this Bond.  The Indenture also permits the Indenture
Trustee to amend or waive certain terms and conditions set forth in the
Indenture without the consent of the Holders of the Bonds of any Series issued
thereunder.

       The Bonds are issuable in fully-registered form only, without coupons,
in denominations as specified in the Series 1998-1 Supplement.  As provided in
the Series 1998-1 Supplement and subject to any limitations on transfer of this
Bond by a Depository or its nominee and certain limitations set forth in the
Series 1998-1 Supplement, the transfer of this Bond is registrable in the Bond
Register upon surrender of this Bond for registration or transfer at the
principal Corporate Trust Office of the Indenture Trustee or such other offices
or agencies appointed by the Indenture Trustee for that purpose and such other
locations provided in the Series 1998-1 Supplement, duly endorsed by, or
accompanied by an assignment in the form below or other written instrument of
transfer in form satisfactory to the Indenture Trustee and the Bond Registrar
duly executed by, the Holder hereof or such Holder's attorney duly authorized
in writing, and thereupon one or more new





                                      -3-
<PAGE>   64
Bonds of the same Class in the same aggregate Principal Balance will be issued
to the designated transferee or transferees.

       As provided in the Indenture and subject to certain limitations therein
set forth, this Bond is exchangeable for a new Bond of the same Class in the
same denomination.  No service charge will be made for any such registration of
transfer or exchange, but the Indenture Trustee 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 Bonds.

       At its option, Bear Stearns Mortgage Capital Corporation ("BSMCC") or
its designee (or if BSMCC or its designee does not exercise such option, the
Issuer) may, upon giving written notice to the Issuer, each Master Servicer,
the Certificate Trustee and the Indenture Trustee, repurchase from the Issuer
all of the remaining Mortgage Loans of any Mortgage Loan Group, and thereby
effect an early termination of the related Certificates and redemption of the
Bonds of the related Bond Group, on any Payment Date when the aggregate
outstanding principal balance of the Mortgage Loans in such Mortgage Loan
Groups is equal to or less than 5% of the aggregate outstanding principal
balance of the Mortgage Loans in such Mortgage Loan Group as of the Cut-off
Date.  Upon any such optional repurchase, the Trust Estate will terminate and
any remaining assets in the Trust Estate shall be released to the repurchasing
party.

       The Issuer, the Indenture Trustee and the Bond Registrar and any agent
of the Issuer, the Indenture Trustee or the Bond Registrar may treat the Person
in whose name this Bond is registered as the owner hereof for all purposes, and
none of the Issuer, the Master Servicers, the Indenture Trustee, the Bond
Registrar or any such agent shall be affected by notice to the contrary.

       Unless the certificate of authentication hereon has been executed by the
Bond Registrar, by manual signature, this Bond shall not be entitled to any
benefit under the Series 1998-1 Supplement or be valid for any purpose.

be conclusive and binding upon such Holder and upon all future holders of this
Bond and of any Bond issued upon the registration of transfer hereof or in
exchange herefor or in lieu hereof whether or not notation of such consent or
waiver is made upon this Bond.  The Indenture also permits the Indenture
Trustee to amend or waive certain terms and conditions set forth in the
Indenture without the consent of the Holders of the Bonds of any Series issued
thereunder.

       The Bonds are issuable in fully-registered form only, without coupons,
in denominations as specified in the Series 1998-1 Supplement.  As provided in
the Series 1998-1 Supplement and subject to any limitations on transfer of this
Bond by a Depository or its nominee and certain limitations set forth in the
Series 1998-1 Supplement, the transfer of this Bond is registrable in the Bond
Register upon surrender of this Bond for registration or transfer at the
principal Corporate Trust Office of the Indenture Trustee or such other offices
or agencies appointed by the Indenture

Supplement, duly endorsed by, or accompanied by an assignment in the form below
or other written instrument of transfer in form satisfactory to the Indenture
Trustee and the Bond Registrar duly executed by, the Holder hereof or such
Holder's attorney duly authorized in writing, and thereupon one or more new
Bonds of the same Class in the same aggregate Principal Balance will be issued
to the designated transferee or transferees.

       As provided in the Indenture and subject to certain limitations therein
set forth, this Bond is exchangeable for a new Bond of the same Class in the
same denomination.  No service charge will be made for any such registration of
transfer or exchange, but the Indenture Trustee 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 Bonds.

       At its option, Bear Stearns Mortgage Capital Corporation ("BSMCC") or
its designee (or if BSMCC or its designee does not exercise such option, the
Issuer) may, upon giving written notice to the Issuer, each Master Servicer,
the Certificate Trustee and the Indenture Trustee, repurchase from the Issuer
all of the remaining Mortgage Loans of any Mortgage Loan Group, and thereby
effect an early termination of the related Certificates and redemption of the
Bonds of the related Bond Group, on any Payment Date when the aggregate
outstanding principal balance of the Mortgage Loans in such Mortgage Loan
Groups is equal to or less than 5% of the aggregate outstanding principal
balance of the Mortgage Loans in such Mortgage Loan Group as of the Cut-off
Date.  Upon any such optional repurchase, the Trust Estate will terminate and
any remaining assets in the Trust Estate shall be released to the repurchasing
party.

       The Issuer, the Indenture Trustee and the Bond Registrar and any agent
of the Issuer, the Indenture Trustee or the Bond Registrar may treat the Person
in whose name this Bond is registered as the owner hereof for all purposes, and
none of the Issuer, the Master Servicers, the Indenture Trustee, the Bond
Registrar or any such agent shall be affected by notice to the contrary.

       Unless the certificate of authentication hereon has been executed by the
Bond Registrar, by manual signature, this Bond shall not be entitled to any
benefit under the Series 1998-1 Supplement or be valid for any purpose.

       CMC SECURITIES CORPORATION III, a corporation duly organized and
existing under the laws of the State of Delaware (herein referred to as the
"Issuer"), for value received hereby promises to pay to CEDE & CO. or
registered assigns, interest on the Class _____________ Notional Amount of the
Class ____________ Bonds in monthly payments on the twenty-fifth day of each
month or, if such day is not a Business Day, then the next succeeding Business
Day (each a "Payment Date"), commencing in April 1998 and ending on or before
the Payment Date occurring in PAYMENT DATE~.  This Bond is one of a duly
authorized issue of non-recourse Bonds of the Issuer, designated as its
Collateralized Mortgage Obligations, Series 1998-1.  The Bonds are issued in
multiple classes under the Issuer's Indenture dated as of March 1, 1998, as
amended (herein called the "Indenture"), to which Indenture and all indentures
supplemental thereto, including the Series 1998-1 Supplement dated as of March
31, 1998 (the "Series 1998-1 Supplement"), between the Issuer and The First
National Bank of Chicago, as indenture trustee (the "Indenture Trustee", which
term includes any successor Trustee under the Indenture), which authorized the
Bonds, reference is hereby made for a statement of the respective rights
thereunder of the Issuer, the Indenture Trustee and the holders of the Bonds
and the terms upon which the Bonds are, and are to be, authenticated and
delivered.

       The Bonds are collateralized by three separate series of mortgage pass-
through certificates (the "Conventional Certificates"), each of which series
evidences the entire beneficial ownership interest in one of three pools of
Mortgage Loans.  Each pool of Mortgage Loans has been deposited into a separate
trust (each, a "Trust") pursuant to the terms of the Pooling and Servicing
Agreement (the "Pooling and Servicing Agreement") dated as of March 1, 1998
among the Issuer, as depositor, Bank of America, FSB and Cendant Mortgage
Corporation, as master servicers (the "Master





                                      -2-
<PAGE>   79
Servicers"), and The First National Bank of Chicago, as certificate trustee
(the "Certificate Trustee").  Each Trust has created a series of Conventional
Certificates for the benefit of the Issuer in exchange for the related pool of
Mortgage Loans.  The Conventional Certificates were pledged to the Indenture
Trustee under the terms of the Indenture.

       All capitalized terms used without definition in this Bond shall have
the meanings assigned to such terms in the Indenture or the Series 1998-1
Supplement, as applicable.

       This Bond does not purport to summarize the Indenture or the Series
1998-1 Supplement and reference should be made to the Indenture and the Series
1998-1 Supplement for the interests, rights and limitations of rights,
benefits, obligations and duties of the holders of the Bond thereunder, and the
rights, duties and immunities of the Indenture Trustee.

       This Bond shall not be entitled to payments of principal. Payments of
interest on this Bond will be paid in accordance with the terms of the Series
1998-1 Supplement and will be made out of the Available Funds for such Payment
Date, to the extent and subject to the limitations set forth in the Series
1998-1 Supplement, on each Payment Date to the Person in whose name this Bond
is registered at the close of business on the last Business Day of the month
immediately preceding the month of such distribution (the "Record Date").  All
sums payable on this Bond are payable in the coin or currency of the United
States of America as at the time of payment is legal tender for the payment of
public and private debts.

       Realized Losses, Net Interest Shortfalls and certain writedown amounts
shall be allocated among the Classes of Bonds on the applicable Payment Date in
the manner set forth in the Series 1998-1 Supplement.  To the extent provided
in the Series 1998-1 Supplement, the Subordinate Bonds will be subordinated in
right of payment to the other Classes of Bonds and each Class of the
Subordinate Bonds will be subordinated in right of payment to each of the other
Classes of Subordinate Bonds with a lower numerical designation, if any.  All
Realized Losses, Net Interest Shortfalls and writedown amounts allocated to any
Class of Bonds will be allocated pro rata among the outstanding Bonds of such
Class, as described in the Series 1998-1 Supplement.

       The Bonds are limited in right of payment to certain collections and
recoveries respecting the Mortgage Loans and certain other assets, all as more
specifically set forth in the Series 1998-1 Supplement.

       So long as this Bond is registered in the name of a Depository or its
nominee, the Indenture Trustee will make payments of principal of and interest
on this Bond by wire transfers of immediately available funds to the Depository
or its nominee.  Otherwise, all payments on this Bond under the Series 1998-1
Supplement will be made by or on behalf of the Indenture Trustee as provided in
the Indenture.  Notwithstanding the above, the final payment on this Bond will
be made after due notice by the Indenture Trustee of the pendency of such
payment and only upon presentation and surrender of this Bond at its principal
Corporate Trust Office or such other offices or agencies appointed by the
Indenture Trustee for that purpose and such other locations provided in the
Series 1998-1 Supplement.

       The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Issuer and the rights of the Holders of the Bonds under the Indenture at any
time by the Issuer with the consent of the Holders of Bonds





                                      -3-

representing two-thirds of the Aggregate Current Principal Amount of all Bonds
at the time Outstanding, in case Outstanding Bonds of all Series are to be
affected, or with the consent of the Holders of two-thirds of the Aggregate
Current Principal Amount of all the Bonds at the time Outstanding of each
Series to be affected, in case one or more, but less than all, of the Series of
Bonds then Outstanding are to be affected; provided however, that 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 of the Indenture 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 of the Indenture 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 of the Indenture shall be made in respect of such Series of Bonds
without the consent of the Holders representing not less than two-thirds of the
Aggregate Current Principal Amount of the Highest Priority Junior Class of such
Series.

       The Indenture also contains provisions permitting the Holders of Bonds
representing specified percentages of the Aggregate Current Principal Amount of
the Bonds of a Series at the time Outstanding on behalf of the Holders of all
the Bonds of such Series, to waive compliance by the Issuer with certain
provisions of the Indenture and certain past defaults under the Indenture and
their consequences.  Any such consent or waiver by the Holder, at the time of
the giving thereof, of this Bond (or any one or more Predecessor Bonds) shall
be conclusive and binding upon such Holder and upon all future holders of this
Bond and of any Bond issued upon the registration of transfer hereof or in
exchange herefor or in lieu hereof whether or not notation of such consent or
waiver is made upon this Bond.  The Indenture also permits the Indenture
Trustee to amend or waive certain terms and conditions set forth in the
Indenture without the consent of the Holders of the Bonds of any Series issued
thereunder.

       The Bonds are issuable in fully-registered form only, without coupons,
in denominations as specified in the Series 1998-1 Supplement.  As provided in
the Series 1998-1 Supplement and subject to any limitations on transfer of this
Bond by a Depository or its nominee and certain limitations set forth in the
Series 1998-1 Supplement, the transfer of this Bond is registrable in the Bond
Register upon surrender of this Bond for registration or transfer at the
principal Corporate Trust Office of the Indenture Trustee or such other offices
or agencies appointed by the Indenture Trustee for that purpose and such other
locations provided in the Series 1998-1 Supplement, duly endorsed by, or
accompanied by an assignment in the form below or other written instrument of
transfer in form satisfactory to the Indenture Trustee and the Bond Registrar
duly executed by, the Holder hereof or such Holder's attorney duly authorized
in writing, and thereupon one or more new Bonds of the same Class in the same
aggregate Principal Balance will be issued to the designated transferee or
transferees.

       As provided in the Indenture and subject to certain limitations therein
set forth, this Bond is exchangeable for a new Bond of the same Class in the
same denomination.  No service charge will be made for any such registration of
transfer or exchange, but the Indenture Trustee 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 Bonds.

Issuer) may, upon giving written notice to the Issuer, each Master Servicer,
the Certificate Trustee and the Indenture Trustee, repurchase from the Issuer
all of the remaining Mortgage Loans of any Mortgage Loan Group, and thereby
effect an early termination of the related Certificates and redemption of the

outstanding principal balance of the Mortgage Loans in such Mortgage Loan
Groups is equal to or less than 5% of the aggregate outstanding principal
balance of the Mortgage Loans in such Mortgage Loan Group as of the Cut-off

Registrar and any agent of the Issuer, the Master Servicers, the Indenture
Trustee or the Bond Registrar may treat the Person in whose name this Bond is

Master Servicers, the Indenture Trustee, the Bond Registrar or any such agent
shall be affected by notice to the contrary.

       Unless the certificate of authentication hereon has been executed by the
Bond Registrar, by manual signature, this Bond shall not be entitled to any
benefit under the Series 1998-1 Supplement or be valid for any purpose.

       CMC SECURITIES CORPORATION III, a corporation duly organized and
existing under the laws of the State of Delaware (herein referred to as the
"Issuer"), for value received hereby promises to pay to CEDE & CO. or
registered assigns, the principal sum of ___________ DOLLARS ($__________) in
monthly payments of principal and interest on the twenty-fifth day of each
month or, if such day is not a Business Day, then the next succeeding Business
Day (each a "Payment Date"), commencing in April 1998 and ending on or before
the Payment Date occurring in____________.  This Bond is one of a duly
authorized issue of non-recourse Bonds of the Issuer, designated as its
Collateralized Mortgage Obligations, Series 1998-1.  The Bonds are issued in
multiple classes under the Issuer's Indenture dated as of March 1, 1998, as
amended (herein called the "Indenture"), to which Indenture and all indentures
supplemental thereto, including the Series 1998-1 Supplement dated as of March
31, 1998 (the
<PAGE>   87
"Series 1998-1 Supplement"), between the Issuer and The First National Bank of
Chicago, as indenture trustee (the "Indenture Trustee", which term includes any
successor Trustee under the Indenture), which authorized the Bonds, reference
is hereby made for a statement of the respective rights thereunder of the
Issuer, the Indenture Trustee and the holders of the Bonds and the terms upon
which the Bonds are, and are to be, authenticated and delivered.

       The Bonds are collateralized by three separate series of mortgage pass-
through certificates (the "Conventional Certificates"), each of which series
evidences the entire beneficial ownership interest in one of three pools of
Mortgage Loans.  Each pool of Mortgage Loans has been deposited into a separate
trust (each, a "Trust") pursuant to the terms of the Pooling and Servicing
Agreement (the "Pooling and Servicing Agreement") dated as of March 1, 1998
among the Issuer, as depositor, Bank of America, FSB and Cendant Mortgage
Corporation, as master servicers (the "Master Servicers"), and The First
National Bank of Chicago, as certificate trustee (the "Certificate Trustee").
Each Trust has created a series of Conventional Certificates for the benefit of
the Issuer in exchange for the related pool of Mortgage Loans.  The
Conventional Certificates were pledged to the Indenture Trustee under the terms
of the Indenture.

       All capitalized terms used without definition in this Bond shall have
the meanings assigned to such terms in the Indenture or the Series 1998-1
Supplement, as applicable.

       This Bond does not purport to summarize the Indenture or the Series
1998-1 Supplement and reference should be made to the Indenture and the Series
1998-1 Supplement for the interests, rights and limitations of rights,
benefits, obligations and duties of the holders of the Bond thereunder, and the
rights, duties and immunities of the Indenture Trustee.

       Payments of principal of and interest on this Bond will be paid in
accordance with the terms of the Series 1998-1 Supplement out of the Available
Funds for such Payment Date, to the extent and subject to the limitations set
forth in the Series 1998-1 Supplement, on each Payment Date to the Person in
whose name this Bond is registered at the close of business on the last
Business Day of the month immediately preceding the month of such distribution
(the "Record Date").  All sums payable on this Bond are payable in the coin or
currency of the United States of America as at the time of payment is legal
tender for the payment of public and private debts.

       Realized Losses, Net Interest Shortfalls and certain writedown amounts
shall be allocated among the Classes of Bonds on the applicable Payment Date in
the manner set forth in the Series 1998-1 Supplement.  To the extent provided
in the Series 1998-1 Supplement, the Subordinate Bonds will be subordinated in
right of payment to the other Classes of Bonds and each Class of the
Subordinate Bonds will be subordinated in right of payment to each of the other
Classes of Subordinate Bonds with a lower numerical designation, if any.  All
Realized Losses, Net Interest Shortfalls and writedown amounts allocated to any
Class of Bonds will be allocated pro rata among the outstanding Bonds of such
Class, as described in the Series 1998-1 Supplement.

       The Bonds are limited in right of payment to certain collections and
recoveries respecting the Mortgage Loans and certain other assets, all as more
specifically set forth in the Series 1998-1 Supplement.

       So long as this Bond is registered in the name of a Depository or its
nominee, the Indenture Trustee will make payments of principal of and interest
on this Bond by wire transfers of immediately available funds to the Depository
or its nominee.  Otherwise, all payments on this Bond under the Series 1998-1
Supplement will be made by or on behalf of the Indenture Trustee as provided in
the Indenture.  Notwithstanding the above, the final payment on this Bond will
be made after due notice by the Indenture Trustee of the pendency of such
payment and only upon presentation and surrender of this Bond at its principal
Corporate Trust Office or such other offices or agencies appointed by the
Indenture Trustee for that purpose and such other locations provided in the
Series 1998-1 Supplement.

       The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Issuer and the rights of the Holders of the Bonds under the Indenture at any
time by the Issuer with the consent of the Holders of Bonds representing
two-thirds of the Aggregate Current Principal Amount of all Bonds at the time
Outstanding, in case Outstanding Bonds of all Series are to be affected, or
with the consent of the Holders of two-thirds of the Aggregate Current
Principal Amount of all the Bonds at the time Outstanding of each Series to be
affected, in case one or more, but less than all, of the Series of Bonds then
Outstanding are to be affected; provided however, that 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 of the Indenture 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 of
the Indenture 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
of the Indenture shall be made in respect of such Series of Bonds without the
consent of the Holders representing not less than two-thirds of the Aggregate
Current Principal Amount of the Highest Priority Junior Class of such Series.

       The Indenture also contains provisions permitting the Holders of Bonds
representing specified percentages of the Aggregate Current Principal Amount of
the Bonds of a Series at the time Outstanding on behalf of the Holders of all
the Bonds of such Series, to waive compliance by the Issuer with certain
provisions of the Indenture and certain past defaults under the Indenture and
their consequences.  Any such consent or waiver by the Holder, at the time of
the giving thereof, of this Bond (or any one or more Predecessor Bonds) shall
be conclusive and binding upon such Holder and upon all future holders of this
Bond and of any Bond issued upon the registration of transfer hereof or in
exchange herefor or in lieu hereof whether or not notation of such consent or
waiver is made upon this Bond.  The Indenture also permits the Indenture
Trustee to amend or waive certain terms and conditions set forth in the
Indenture without the consent of the Holders of the Bonds of any Series issued
thereunder.

       The Bonds are issuable in fully-registered form only, without coupons,
in denominations as specified in the Series 1998-1 Supplement.  As provided in
the Series 1998-1 Supplement and subject to any limitations on transfer of this
Bond by a Depository or its nominee and certain limitations set forth in the
Series 1998-1 Supplement, the transfer of this Bond is registrable in the Bond
Register upon surrender of this Bond for registration or transfer at the
principal Corporate

appointed by the Indenture Trustee for that purpose and such other locations
provided in the Series 1998-1 Supplement, duly endorsed by, or accompanied by
an assignment in the form below or other written instrument of transfer in form
satisfactory to the Indenture Trustee and the Bond Registrar duly executed by,
the Holder hereof or such Holder's attorney duly authorized in writing, and
thereupon one or more new Bonds of the same Class in the same aggregate
Principal Balance will be issued to the designated transferee or transferees.

       As provided in the Indenture and subject to certain limitations therein
set forth, this Bond is exchangeable for a new Bond of the same Class in the
same denomination.  No service charge will be made for any such registration of
transfer or exchange, but the Indenture Trustee 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 Bonds.

       At its option, Bear Stearns Mortgage Capital Corporation ("BSMCC") or
its designee (or if BSMCC or its designee does not exercise such option, the
Issuer) may, upon giving written notice to the Issuer, each Master Servicer,
the Certificate Trustee and the Indenture Trustee, repurchase from the Issuer
all of the remaining Mortgage Loans of any Mortgage Loan Group, and thereby
effect an early termination of the related Certificates and redemption of the
Bonds of the related Bond Group, on any Payment Date when the aggregate
outstanding principal balance of the Mortgage Loans in such Mortgage Loan
Groups is equal to or less than 5% of the aggregate outstanding principal
balance of the Mortgage Loans in such Mortgage Loan Group as of the Cut-off
Date.  Upon any such optional repurchase, the Trust Estate will terminate and
any remaining assets in the Trust Estate shall be released to the repurchasing
party.

       The Issuer, the Indenture Trustee and the Bond Registrar and any agent
of the Issuer, the Indenture Trustee or the Bond Registrar may treat the Person
in whose name this Bond is registered as the owner hereof for all purposes, and
none of the Issuer, the Master Servicers, the Indenture Trustee, the Bond
Registrar or any such agent shall be affected by notice to the contrary.

       Unless the certificate of authentication hereon has been executed by the
Bond Registrar, by manual signature, this Bond shall not be entitled to any
benefit under the Series 1998-1 Supplement or be valid for any purpose.

1998-1.  The Bonds are issued in multiple classes under the Issuer's Indenture
dated as of March 1, 1998, as amended (herein called the "Indenture"), to which
Indenture and all indentures supplemental thereto, including the Series 1998-1
Supplement dated as of March 31, 1998 (the "Series 1998-1 Supplement"), between
the Issuer and The First National Bank of Chicago, as indenture trustee (the
"Indenture Trustee", which term includes any successor Trustee under the
Indenture), which authorized the Bonds, reference is hereby made for a
statement of the respective rights thereunder of the Issuer, the Indenture
Trustee and the holders of the Bonds and the terms upon which the Bonds are,
and are to be, authenticated and delivered.

       The Bonds are collateralized by three separate series of mortgage pass-
through certificates (the "Conventional Certificates"), each of which series
evidences the entire beneficial ownership interest in one of three pools of
Mortgage Loans.  Each pool of Mortgage Loans has been deposited into a separate
trust (each, a "Trust") pursuant to the terms of the Pooling and Servicing
Agreement (the "Pooling and Servicing Agreement") dated as of March 1, 1998
among the Issuer, as depositor, Bank of America, FSB and Cendant Mortgage
Corporation, as master servicers (the "Master Servicers"), and The First
National Bank of Chicago, as certificate trustee (the "Certificate Trustee").
Each Trust has created a series of Conventional Certificates for the benefit of
the Issuer in exchange for the related pool of Mortgage Loans.  The
Conventional Certificates were pledged to the Indenture Trustee under the terms
of the Indenture.

       All capitalized terms used without definition in this Bond shall have
the meanings assigned to such terms in the Indenture or the Series 1998-1
Supplement, as applicable.

       This Bond does not purport to summarize the Indenture or the Series
1998-1 Supplement and reference should be made to the Indenture and the Series
1998-1 Supplement for the interests, rights and limitations of rights,
benefits, obligations and duties of the holders of the Bond thereunder, and the
rights, duties and immunities of the Indenture Trustee.

       Payments of principal of and interest on this Bond will be paid in
accordance with the terms of the Series 1998-1 Supplement and will be made out
of the Available Funds for such Payment Date, to the extent and subject to the
limitations set forth in the Series 1998-1 Supplement, on each Payment Date to
the Person in whose name this Bond is registered at the close of business on
the last Business Day of the month immediately preceding the month of such
distribution (the "Record Date").  All sums payable on this Bond are payable in
the coin or currency of the United States of America as at the time of payment
is legal tender for the payment of public and private debts.

       Realized Losses, Net Interest Shortfalls and certain writedown amounts
shall be allocated among the Classes of Bonds on the applicable Payment Date in
the manner set forth in the Series 1998-1 Supplement.  To the extent provided
in the Series 1998-1 Supplement, the Subordinate Bonds will be subordinated in
right of payment to the other Classes of Bonds and each Class of the
Subordinate Bonds will be subordinated in right of payment to each of the other
Classes of Subordinate Bonds with a lower numerical designation, if any.  All
Realized Losses, Net Interest Shortfalls and writedown amounts allocated to any
Class of Bonds will be allocated pro rata among the outstanding Bonds of such
Class, as described in the Series 1998-1 Supplement.

       The Bonds are limited in right of payment to certain collections and
recoveries respecting the Mortgage Loans, all as more specifically set forth in
the Series 1998-1 Supplement.

       So long as this Bond is registered in the name of a Depository or its
nominee, the Indenture Trustee will make payments of principal of and interest
on this Bond by wire transfers of immediately available funds to the Depository
or its nominee.  Otherwise, all payments on this Bond under the Series 1998-1
Supplement will be made by or on behalf of the Indenture Trustee as provided in
the Indenture.  Notwithstanding the above, the final payment on this Bond will
be made after due notice by the Indenture Trustee of the pendency of such
payment and only upon presentation and surrender of this Bond at its principal
Corporate Trust Office or such other offices or agencies appointed by the
Indenture Trustee for that purpose and such other locations provided in the
Series 1998-1 Supplement.

       The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Issuer and the rights of the Holders of the Bonds under the Indenture at any
time by the Issuer with the consent of the Holders of Bonds representing
two-thirds of the Aggregate Current Principal Amount of all Bonds at the time
Outstanding, in case Outstanding Bonds of all Series are to be affected, or
with the consent of the Holders of two-thirds of the Aggregate Current
Principal Amount of all the Bonds at the time Outstanding of each Series to be
affected, in case one or more, but less than all, of the Series of Bonds then
Outstanding are to be affected; provided however, that 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 of the Indenture 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 of
the Indenture 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
of the Indenture shall be made in respect of such Series of Bonds without the
consent of the Holders representing not less than two-thirds of the Aggregate
Current Principal Amount of the Highest Priority Junior Class of such Series.

       The Indenture also contains provisions permitting the Holders of Bonds
representing specified percentages of the Aggregate Current Principal Amount of
the Bonds of a Series at the time Outstanding on behalf of the Holders of all
the Bonds of such Series, to waive compliance by the Issuer with certain
provisions of the Indenture and certain past defaults under the Indenture and
their consequences.  Any such consent or waiver by the Holder, at the time of
the giving thereof, of this Bond (or any one or more Predecessor Bonds) shall
be conclusive and binding upon such Holder and upon all future holders of this
Bond and of any Bond issued upon the registration of transfer hereof or in
exchange herefor or in lieu hereof whether or not notation of such consent or
waiver is made upon this Bond.  The Indenture also permits the Indenture
Trustee to amend or waive certain terms and conditions set forth in the
Indenture without the consent of the Holders of the Bonds of any Series issued
thereunder.

       The Bonds are issuable in fully-registered form only, without coupons,
in denominations as specified in the Series 1998-1 Supplement.  As provided in
the Series 1998-1 Supplement and subject to any limitations on transfer of this
Bond by a Depository or its nominee and certain limitations set forth in the
Series 1998-1 Supplement, the transfer of this Bond is registrable in the Bond
Register upon surrender of this Bond for registration or transfer at the
principal Corporate Trust Office of the Indenture Trustee or such other offices
or agencies appointed by the Indenture Trustee for that purpose and such other
locations provided in the Series 1998-1 Supplement, duly

endorsed by, or accompanied by an assignment in the form below or other written
instrument of transfer in form satisfactory to the Indenture Trustee and the
Bond Registrar duly executed by, the Holder hereof or such Holder's attorney
duly authorized in writing, and thereupon one or more new Bonds of the same
Class in the same aggregate Principal Balance will be issued to the designated
transferee or transferees.

       As provided in the Indenture and subject to certain limitations therein
set forth, this Bond is exchangeable for a new Bond of the same Class in the
same denomination.  No service charge will be made for any such registration of
transfer or exchange, but the Indenture Trustee 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 Bonds.

       At its option, Bear Stearns Mortgage Capital Corporation ("BSMCC") or
its designee (or if BSMCC or its designee does not exercise such option, the
Issuer) may, upon giving written notice to the Issuer, each Master Servicer,
the Certificate Trustee and the Indenture Trustee, repurchase from the Issuer
all of the remaining Mortgage Loans of any Mortgage Loan Group, and thereby
effect an early termination of the related Certificates and redemption of the
Bonds of the related Bond Group, on any Payment Date when the aggregate
outstanding principal balance of the Mortgage Loans in such Mortgage Loan
Groups is equal to or less than 5% of the aggregate outstanding principal
balance of the Mortgage Loans in such Mortgage Loan Group as of the Cut-off
Date.  Upon any such optional repurchase, the Trust Estate will terminate and
any remaining assets in the Trust Estate shall be released to the repurchasing
party.

       The Issuer, the Indenture Trustee and the Bond Registrar and any agent
of the Issuer, the Indenture Trustee or the Bond Registrar may treat the Person
in whose name this Bond is registered as the owner hereof for all purposes, and
none of the Issuer, the Master Servicers, the Indenture Trustee, the Bond
Registrar or any such agent shall be affected by notice to the contrary.

       Unless the certificate of authentication hereon has been executed by the
Bond Registrar, by manual signature, this Bond shall not be entitled to any
benefit under the Series 1998-1 Supplement or be valid for any purpose.

accordance with the terms of the Series 1998-1 Supplement and will be made out
of the Available Funds for such Payment Date, to the extent and subject to the

Classes of Subordinate Bonds with a lower numerical designation, if any.  All
Realized Losses, Net Interest Shortfalls and writedown amounts allocated to any

       The Bonds are limited in right of payment to certain collections and
recoveries respecting the Mortgage Loans and certain other assets, all as more
specifically set forth in the Series 1998-1 Supplement.

       So long as this Bond is registered in the name of a Depository or its
nominee, the Indenture Trustee will make payments of principal of and interest
on this Bond by wire transfers of immediately available funds to the Depository
or its nominee.  Otherwise, all payments on this Bond under the Series 1998-1
Supplement will be made by or on behalf of the Indenture Trustee as provided in
the Indenture.  Notwithstanding the above, the final payment on this Bond will
be made after due notice by the Indenture Trustee of the pendency of such
payment and only upon presentation and surrender of this Bond at its principal
Corporate Trust Office or such other offices or agencies appointed by the
Indenture Trustee for that purpose and such other locations provided in the
Series 1998-1 Supplement.

       The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Issuer and the rights of the Holders of the Bonds under the Indenture at any
time by the Issuer with the consent of the Holders of Bonds representing
two-thirds of the Aggregate Current Principal Amount of all Bonds at the time
Outstanding, in case Outstanding Bonds of all Series are to be affected, or
with the consent of the Holders of two-thirds of the Aggregate Current
Principal Amount of all the Bonds at the time Outstanding of each Series to be
affected, in case one or more, but less than all, of the Series of Bonds then
Outstanding are to be affected; provided however, that 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 of the Indenture 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 of
the Indenture 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
of the Indenture shall be made in respect of such Series of Bonds without the
consent of the Holders representing not less than two-thirds of the Aggregate
Current Principal Amount of the Highest Priority Junior Class of such Series.

       The Indenture also contains provisions permitting the Holders of Bonds
representing specified percentages of the Aggregate Current Principal Amount of
the Bonds of a Series at the time Outstanding on behalf of the Holders of all
the Bonds of such Series, to waive compliance by the Issuer with certain
provisions of the Indenture and certain past defaults under the Indenture and
their consequences.  Any such consent or waiver by the Holder, at the time of
the giving thereof, of this Bond (or any one or more Predecessor Bonds) shall
be conclusive and binding upon such Holder and upon all future holders of this
Bond and of any Bond issued upon the registration of transfer hereof or in
exchange herefor or in lieu hereof whether or not notation of such consent or
waiver is made upon this Bond.  The Indenture also permits the Indenture
Trustee to amend or waive certain terms





                                      -4-
<PAGE>   107
and conditions set forth in the Indenture without the consent of the Holders of
the Bonds of any Series issued thereunder.

       The Bonds are issuable in fully-registered form only, without coupons,
in denominations as specified in the Series 1998-1 Supplement.  As provided in
the Series 1998-1 Supplement and subject to any limitations on transfer of this
Bond by a Depository or its nominee and certain limitations set forth in the
Series 1998-1 Supplement, the transfer of this Bond is registrable in the Bond
Register upon surrender of this Bond for registration or transfer at the
principal Corporate Trust Office of the Indenture Trustee or such other offices
or agencies appointed by the Indenture Trustee for that purpose and such other
locations provided in the Series 1998-1 Supplement, duly endorsed by, or
accompanied by an assignment in the form below or other written instrument of
transfer in form satisfactory to the Indenture Trustee and the Bond Registrar
duly executed by, the Holder hereof or such Holder's attorney duly authorized
in writing, and thereupon one or more new Bonds of the same Class in the same
aggregate Principal Balance will be issued to the designated transferee or
transferees.

       As provided in the Indenture and subject to certain limitations therein
set forth, this Bond is exchangeable for a new Bond of the same Class in the
same denomination.  No service charge will be made for any such registration of
transfer or exchange, but the Indenture Trustee 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 Bonds.

       At its option, Bear Stearns Mortgage Capital Corporation ("BSMCC") or
its designee (or if BSMCC or its designee does not exercise such option, the
Issuer) may, upon giving written notice to the Issuer, each Master Servicer,
the Certificate Trustee and the Indenture Trustee, repurchase from the Issuer
all of the remaining Mortgage Loans of any Mortgage Loan Group, and thereby
effect an early termination of the related Certificates and redemption of the
Bonds of the related Bond Group, on any Payment Date when the aggregate
outstanding principal balance of the Mortgage Loans in such Mortgage Loan
Groups is equal to or less than 5% of the aggregate outstanding principal
balance of the Mortgage Loans in such Mortgage Loan Group as of the Cut-off
Date.  Upon any such optional repurchase, the Trust Estate will terminate and
any remaining assets in the Trust Estate shall be released to the repurchasing
party.

       The Issuer, the Indenture Trustee and the Bond Registrar and any agent
of the Issuer, the Indenture Trustee or the Bond Registrar may treat the Person
in whose name this Bond is registered as the owner hereof for all purposes, and
none of the Issuer, the Master Servicers, the Indenture Trustee, the Bond
Registrar or any such agent shall be affected by notice to the contrary.

       Unless the certificate of authentication hereon has been executed by the
Bond Registrar, by manual signature, this Bond shall not be entitled to any
benefit under the Series 1998-1 Supplement or be valid for any purpose.

ORGANIZATION, SUCH REGISTRATION SHALL BE DEEMED TO BE OF NO LEGAL FORCE OR
EFFECT WHATSOEVER AND SUCH PERSON SHALL NOT BE DEEMED TO BE A SECURITYHOLDER
FOR ANY PURPOSE HEREUNDER, INCLUDING, BUT NOT LIMITED TO, THE RECEIPT OF
DISTRIBUTIONS ON THIS BOND.  EACH HOLDER OF THIS BOND, BY ACCEPTANCE OF THIS

6.50% BOND INTEREST RATE                                 CERTIFICATE NUMBER 0001

       CMC SECURITIES CORPORATION III, a corporation duly organized and
existing under the laws of the State of Delaware (herein referred to as the
"Issuer"), for value received hereby promises to pay to BEAR STEARNS SECURITIES
CORP. or registered assigns, the principal sum of FIFTY AND NO/100 DOLLARS
($50.00) in monthly payments of principal and interest on the twenty-fifth day
of each month or, if such day is not a Business Day, then the next succeeding
business day (each a "Payment Date"), commencing in April 1998 and ending on or
before the Payment Date occurring in April 2013.  This Bond is one of a duly
authorized issue of non-recourse Bonds of the Issuer, designated as its
Collateralized Mortgage Obligations, Series 1998-1.  The Bonds are issued in
multiple classes under the Issuer's Indenture dated as of March 1, 1998, as
amended (herein called





                                      -2-
<PAGE>   114
the "Indenture"), to which Indenture and all indentures supplemental thereto,
including the Series 1998-1 Supplement dated as of March 31, 1998 (the "Series
1998-1 Supplement"), between the Issuer and The First National Bank of Chicago,
as indenture trustee (the "Indenture Trustee", which term includes any
successor Trustee under the Indenture), which authorized the Bonds, reference
is hereby made for a statement of the respective rights thereunder of the
Issuer, the Indenture Trustee and the holders of the Bonds and the terms upon
which the Bonds are, and are to be, authenticated and delivered.

       The Bonds are collateralized by three separate series of mortgage pass-
through certificates (the "Conventional Certificates"), each of which series
evidences the entire beneficial ownership interest in one of three pools of
Mortgage Loans.  Each pool of Mortgage Loans has been deposited into a separate
trust (each, a "Trust") pursuant to the terms of the Pooling and Servicing
Agreement (the "Pooling and Servicing Agreement") dated as of March 1, 1998
among the Issuer, as depositor, Bank of America, FSB and Cendant Mortgage
Corporation, as master servicers (the "Master Servicers"), and The First
National Bank of Chicago, as certificate trustee (the "Certificate Trustee").
Each Trust has created a series of Conventional Certificates for the benefit of
the Issuer in exchange for the related pool of Mortgage Loans.  The
Conventional Certificates were pledged to the Indenture Trustee under the terms
of the Indenture.

       All capitalized terms used without definition in this Bond shall have
the meanings assigned to such terms in the Indenture or the Series 1998-1
Supplement, as applicable.

       This Bond does not purport to summarize the Indenture or the Series
1998-1 Supplement and reference should be made to the Indenture and the Series
1998-1 Supplement for the interests, rights and limitations of rights,
benefits, obligations and duties of the holders of the Bond thereunder, and the
rights, duties and immunities of the Indenture Trustee.

       Payments of principal of and interest on this Bond will be paid in
accordance with the terms of the Series 1998-1 Supplement and will be made out
of the Available Funds for such Payment Date, to the extent and subject to the
limitations set forth in the Series 1998-1 Supplement, on each Payment Date to
the Person in whose name this Bond is registered at the close of business on
the last Business Day of the month immediately preceding the month of such
distribution (the "Record Date").  All sums payable on this Bond are payable in
the coin or currency of the United States of America as at the time of payment
is legal tender for the payment of public and private debts.

       Realized Losses, Net Interest Shortfalls and certain writedown amounts
shall be allocated among the Classes of Bonds on the applicable Payment Date in
the manner set forth in the Series 1998-1 Supplement.  To the extent provided
in the Series 1998-1 Supplement, the Subordinate Bonds will be subordinated in
right of payment to the other Classes of Bonds and each Class of the
Subordinate Bonds will be subordinated in right of payment to each of the other
Classes of Subordinate Bonds with a lower numerical designation, if any.  All
Realized Losses, Net Interest Shortfalls and writedown amounts allocated to any
Class of Bonds will be allocated pro rata among the outstanding Bonds of such
Class, as described in the Series 1998-1 Supplement.





                                      -3-
<PAGE>   115
       The Bonds are limited in right of payment to certain collections and
recoveries respecting the Mortgage Loans and certain other assets, all as more
specifically set forth in the Series 1998-1 Supplement.

       So long as this Bond is registered in the name of a Depository or its
nominee, the Indenture Trustee will make payments of principal of and interest
on this Bond by wire transfers of immediately available funds to the Depository
or its nominee.  Otherwise, all payments on this Bond under the Series 1998-1
Supplement will be made by or on behalf of the Indenture Trustee as provided in
the Indenture.  Notwithstanding the above, the final payment on this Bond will
be made after due notice by the Indenture Trustee of the pendency of such
payment and only upon presentation and surrender of this Bond at its principal
Corporate Trust Office or such other offices or agencies appointed by the
Indenture Trustee for that purpose and such other locations provided in the
Series 1998-1 Supplement.

       The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Issuer and the rights of the Holders of the Bonds under the Indenture at any
time by the Issuer with the consent of the Holders of Bonds representing
two-thirds of the Aggregate Current Principal Amount of all Bonds at the time
Outstanding, in case Outstanding Bonds of all Series are to be affected, or
with the consent of the Holders of two-thirds of the Aggregate Current
Principal Amount of all the Bonds at the time Outstanding of each Series to be
affected, in case one or more, but less than all, of the Series of Bonds then
Outstanding are to be affected; provided however, that 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 of the Indenture 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 of
the Indenture 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
of the Indenture shall be made in respect of such Series of Bonds without the
consent of the Holders representing not less than two-thirds of the Aggregate
Current Principal Amount of the Highest Priority Junior Class of such Series.

       The Indenture also contains provisions permitting the Holders of Bonds
representing specified percentages of the Aggregate Current Principal Amount of
the Bonds of a Series at the time Outstanding on behalf of the Holders of all
the Bonds of such Series, to waive compliance by the Issuer with certain
provisions of the Indenture and certain past defaults under the Indenture and
their consequences.  Any such consent or waiver by the Holder, at the time of
the giving thereof, of this Bond (or any one or more Predecessor Bonds) shall
be conclusive and binding upon such Holder and upon all future holders of this
Bond and of any Bond issued upon the registration of transfer hereof or in
exchange herefor or in lieu hereof whether or not notation of such consent or
waiver is made upon this Bond.  The Indenture also permits the Indenture
Trustee to amend or waive certain terms





                                      -4-
<PAGE>   116
and conditions set forth in the Indenture without the consent of the Holders of
the Bonds of any Series issued thereunder.

       The Bonds are issuable in fully-registered form only, without coupons,
in denominations as specified in the Series 1998-1 Supplement.  As provided in
the Series 1998-1 Supplement and subject to any limitations on transfer of this
Bond by a Depository or its nominee and certain limitations set forth in the
Series 1998-1 Supplement, the transfer of this Bond is registrable in the Bond
Register upon surrender of this Bond for registration or transfer at the
principal Corporate Trust Office of the Indenture Trustee or such other offices
or agencies appointed by the Indenture Trustee for that purpose and such other
locations provided in the Series 1998-1 Supplement, duly endorsed by, or
accompanied by an assignment in the form below or other written instrument of
transfer in form satisfactory to the Indenture Trustee and the Bond Registrar
duly executed by, the Holder hereof or such Holder's attorney duly authorized
in writing, and thereupon one or more new Bonds of the same Class in the same
aggregate Principal Balance will be issued to the designated transferee or
transferees.

       As provided in the Indenture and subject to certain limitations therein
set forth, this Bond is exchangeable for a new Bond of the same Class in the
same denomination.  No service charge will be made for any such registration of
transfer or exchange, but the Indenture Trustee 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 Bonds.

       At its option, Bear Stearns Mortgage Capital Corporation ("BSMCC") or
its designee (or if BSMCC or its designee does not exercise such option, the
Issuer) may, upon giving written notice to the Issuer, each Master Servicer,
the Certificate Trustee and the Indenture Trustee, repurchase from the Issuer
all of the remaining Mortgage Loans of any Mortgage Loan Group, and thereby
effect an early termination of the related Certificates and redemption of the
Bonds of the related Bond Group, on any Payment Date when the aggregate
outstanding principal balance of the Mortgage Loans in such Mortgage Loan
Groups is equal to or less than 5% of the aggregate outstanding principal
balance of the Mortgage Loans in such Mortgage Loan Group as of the Cut-off
Date.  Upon any such optional repurchase, the Trust Estate will terminate and
any remaining assets in the Trust Estate shall be released to the repurchasing
party.

       The Issuer, the Indenture Trustee and the Bond Registrar and any agent

VARIABLE BOND INTEREST RATE                              CERTIFICATE NUMBER 0001

       CMC SECURITIES CORPORATION III, a corporation duly organized and
existing under the laws of the State of Delaware (herein referred to as the
"Issuer"), for value received hereby promises to pay to BEAR STEARNS SECURITIES
CORP. or registered assigns, the principal sum of FIFTY AND NO/100 DOLLARS
($50.00) in monthly payments of principal and interest on the twenty-fifth day
of each month or, if such day is not a Business Day, then the next succeeding
business day (each a "Payment Date"), commencing in April 1998 and ending on or
before the Payment Date occurring in April 2028.  This Bond is one of a duly
authorized issue of non-recourse Bonds of the Issuer, designated as its
Collateralized Mortgage Obligations, Series 1998-1.  The Bonds are issued in
multiple classes under the Issuer's Indenture dated as of March 1, 1998, as
amended (herein called





                                      -2-
<PAGE>   123
the "Indenture"), to which Indenture and all indentures supplemental thereto,
including the Series 1998-1 Supplement dated as of March 31, 1998 (the "Series
1998-1 Supplement"), between the Issuer and The First National Bank of Chicago,
as indenture trustee (the "Indenture Trustee", which term includes any
successor Trustee under the Indenture), which authorized the Bonds, reference
is hereby made for a statement of the respective rights thereunder of the
Issuer, the Indenture Trustee and the holders of the Bonds and the terms upon
which the Bonds are, and are to be, authenticated and delivered.

       The Bonds are collateralized by three separate series of mortgage pass-
through certificates (the "Conventional Certificates"), each of which series
evidences the entire beneficial ownership interest in one of three pools of
Mortgage Loans.  Each pool of Mortgage Loans has been deposited into a separate
trust (each, a "Trust") pursuant to the terms of the Pooling and Servicing
Agreement (the "Pooling and Servicing Agreement") dated as of March 1, 1998
among the Issuer, as depositor, Bank of America, FSB and Cendant Mortgage
Corporation, as master servicers (the "Master Servicers"), and The First
National Bank of Chicago, as certificate trustee (the "Certificate Trustee").
Each Trust has created a series of Conventional Certificates for the benefit of
the Issuer in exchange for the related pool of Mortgage Loans.  The
Conventional Certificates were pledged to the Indenture Trustee under the terms
of the Indenture.

       All capitalized terms used without definition in this Bond shall have
the meanings assigned to such terms in the Indenture or the Series 1998-1
Supplement, as applicable.

       This Bond does not purport to summarize the Indenture or the Series
1998-1 Supplement and reference should be made to the Indenture and the Series
1998-1 Supplement for the interests, rights and limitations of rights,
benefits, obligations and duties of the holders of the Bond thereunder, and the
rights, duties and immunities of the Indenture Trustee.

       Payments of principal of and interest on this Bond will be paid in
accordance with the terms of the Series 1998-1 Supplement and will be made out
of the Available Funds for such Payment Date, to the extent and subject to the
limitations set forth in the Series 1998-1 Supplement, on each Payment Date to
the Person in whose name this Bond is registered at the close of business on
the last Business Day of the month immediately preceding the month of such
distribution (the "Record Date").  All sums payable on this Bond are payable in
the coin or currency of the United States of America as at the time of payment
is legal tender for the payment of public and private debts.

       Realized Losses, Net Interest Shortfalls and certain writedown amounts
shall be allocated among the Classes of Bonds on the applicable Payment Date in
the manner set forth in the Series 1998-1 Supplement.  To the extent provided
in the Series 1998-1 Supplement, the Subordinate Bonds will be subordinated in
right of payment to the other Classes of Bonds and each Class of the
Subordinate Bonds will be subordinated in right of payment to each of the other
Classes of Subordinate Bonds with a lower numerical designation, if any.  All
Realized Losses, Net Interest Shortfalls and writedown amounts allocated to any
Class of Bonds will be allocated pro rata among the outstanding Bonds of such
Class, as described in the Series 1998-1 Supplement.





                                      -3-
<PAGE>   124
       The Bonds are limited in right of payment to certain collections and
recoveries respecting the Mortgage Loans and certain other assets, all as more
specifically set forth in the Series 1998-1 Supplement.

       So long as this Bond is registered in the name of a Depository or its
nominee, the Indenture Trustee will make payments of principal of and interest
on this Bond by wire transfers of immediately available funds to the Depository
or its nominee.  Otherwise, all payments on this Bond under the Series 1998-1
Supplement will be made by or on behalf of the Indenture Trustee as provided in
the Indenture.  Notwithstanding the above, the final payment on this Bond will
be made after due notice by the Indenture Trustee of the pendency of such
payment and only upon presentation and surrender of this Bond at its principal
Corporate Trust Office or such other offices or agencies appointed by the
Indenture Trustee for that purpose and such other locations provided in the
Series 1998-1 Supplement.

       The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Issuer and the rights of the Holders of the Bonds under the Indenture at any
time by the Issuer with the consent of the Holders of Bonds representing
two-thirds of the Aggregate Current Principal Amount of all Bonds at the time
Outstanding, in case Outstanding Bonds of all Series are to be affected, or
with the consent of the Holders of two-thirds of the Aggregate Current
Principal Amount of all the Bonds at the time Outstanding of each Series to be
affected, in case one or more, but less than all, of the Series of Bonds then
Outstanding are to be affected; provided however, that 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 of the Indenture 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 of
the Indenture 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
of the Indenture shall be made in respect of such Series of Bonds without the
consent of the Holders representing not less than two-thirds of the Aggregate
Current Principal Amount of the Highest Priority Junior Class of such Series.

       The Indenture also contains provisions permitting the Holders of Bonds
representing specified percentages of the Aggregate Current Principal Amount of
the Bonds of a Series at the time Outstanding on behalf of the Holders of all
the Bonds of such Series, to waive compliance by the Issuer with certain
provisions of the Indenture and certain past defaults under the Indenture and
their consequences.  Any such consent or waiver by the Holder, at the time of
the giving thereof, of this Bond (or any one or more Predecessor Bonds) shall
be conclusive and binding upon such Holder and upon all future holders of this
Bond and of any Bond issued upon the registration of transfer hereof or in
exchange herefor or in lieu hereof whether or not notation of such consent or
waiver is made upon this Bond.  The Indenture also permits the Indenture
Trustee to amend or waive certain terms





                                      -4-
<PAGE>   125
and conditions set forth in the Indenture without the consent of the Holders of
the Bonds of any Series issued thereunder.

       The Bonds are issuable in fully-registered form only, without coupons,
in denominations as specified in the Series 1998-1 Supplement.  As provided in
the Series 1998-1 Supplement and subject to any limitations on transfer of this
Bond by a Depository or its nominee and certain limitations set forth in the
Series 1998-1 Supplement, the transfer of this Bond is registrable in the Bond
Register upon surrender of this Bond for registration or transfer at the
principal Corporate Trust Office of the Indenture Trustee or such other offices
or agencies appointed by the Indenture Trustee for that purpose and such other
locations provided in the Series 1998-1 Supplement, duly endorsed by, or
accompanied by an assignment in the form below or other written instrument of
transfer in form satisfactory to the Indenture Trustee and the Bond Registrar
duly executed by, the Holder hereof or such Holder's attorney duly authorized
in writing, and thereupon one or more new Bonds of the same Class in the same
aggregate Principal Balance will be issued to the designated transferee or
transferees.

       As provided in the Indenture and subject to certain limitations therein
set forth, this Bond is exchangeable for a new Bond of the same Class in the
same denomination.  No service charge will be made for any such registration of
transfer or exchange, but the Indenture Trustee 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 Bonds.

       At its option, Bear Stearns Mortgage Capital Corporation ("BSMCC") or
its designee (or if BSMCC or its designee does not exercise such option, the
Issuer) may, upon giving written notice to the Issuer, each Master Servicer,
the Certificate Trustee and the Indenture Trustee, repurchase from the Issuer
all of the remaining Mortgage Loans of any Mortgage Loan Group, and thereby
effect an early termination of the related Certificates and redemption of the
Bonds of the related Bond Group, on any Payment Date when the aggregate
outstanding principal balance of the Mortgage Loans in such Mortgage Loan
Groups is equal to or less than 5% of the aggregate outstanding principal
balance of the Mortgage Loans in such Mortgage Loan Group as of the Cut-off
Date.  Upon any such optional repurchase, the Trust Estate will terminate and
any remaining assets in the Trust Estate shall be released to the repurchasing
party.

       The Issuer, the Indenture Trustee and the Bond Registrar and any agent
of the Issuer, the Indenture Trustee or the Bond Registrar may treat the Person
in whose name this Bond is registered as the owner hereof for all purposes, and
none of the Issuer, the Master Servicers, the Indenture Trustee, the Bond
Registrar or any such agent shall be affected by notice to the contrary.

       Unless the certificate of authentication hereon has been executed by the
Bond Registrar, by manual signature, this Bond shall not be entitled to any
benefit under the Series 1998-1 Supplement or be valid for any purpose.

                                (RESIDUAL BONDS)
                                                                          [DATE]

                                   )       ss.:
COUNTY OF __________________       )


    The undersigned, _______________________, being first duly sworn, deposes,
represents and warrants:

         1.      That he is a [Title of Officer] of [Name of Owner], a [savings
institution][corporation] duly organized and existing under the laws of the
State of _______________ (the "Owner"), record or beneficial owner of CMC
Securities Corporation III Collateralized Mortgage Obligations, Series 1998-1,
[Class R-1][Class R-2][Class R-3] Bonds (the "Residual Bonds") having an
initial Class Current Principal Balance of $_______________, on behalf of which
he makes this affidavit and agreement.  The Bonds were issued pursuant to the
Indenture (the "Indenture") dated as of March 1, 1998 and the Series 1998-1
Supplement thereto (the "Series Supplement") dated as of March 31, 1998, each
between CMC Securities Corporation III and The First National Bank of Chicago,
as Indenture Trustee (the "Indenture Trustee").

         2.      That the Owner (i) is and will be a "Permitted Transferee" as
of ______________, ______ and (ii) is acquiring the Bonds for its own account
or for the account of another Owner from which it has received an affidavit in
substantially the same form as this affidavit.  A "Permitted Transferee" is any
person other than a "disqualified organization" or a Non-U.S. Person.  For this
purpose, a "disqualified organization" means any of the following:  (i) the
United States, any State or political subdivision thereof, any foreign
government, any international organization, or any agency or instrumentality of
any of the foregoing, (ii) any organization (other than a farmers' cooperative
described in Section 521 of the Internal Revenue Code of 1986 (the "Code)) that
is exempt from the tax imposed by Chapter 1 of the Code and not subject to the
tax imposed by Section 511 of the Code, (iii) rural electric or telephone
cooperatives described in Section 1381(a)(2)(C) of the Code or (iv) any other
Person whose holding of an ownership interest in a Residual Bond may cause the
related REMIC to incur a liability for any tax imposed under the Code that
would not otherwise be imposed but for the transfer of an ownership interest in
a Residual Bond to such Person.  For purposes of clause (i) of the previous
sentence, a corporation shall not be treated as an instrumentality of the
United States or of any State or political subdivision thereof, if (i) all of
the activities of such corporation are subject to the tax imposed by Chapter 1
of the Code, and (ii) a majority of the board of directors of such corporation
is not selected by the United States or any State or political subdivision
thereof (except that this clause (ii) shall not apply to the Federal Home Loan
Mortgage Corporation).  The terms "United States," "State" and "international
organization" shall have the meanings set forth in Section 7701 of the Code or
successor provisions.
<PAGE>   131
         3.      That the Owner is aware (i) of the tax that would be imposed
on the Trust Estate if a Residual Bond is transferred to a disqualified
organization under Section 860E(e) of the Code and that any Owner that is a
disqualified organization will be obligated to reimburse the Trust Estate for
any such tax; (ii) that such tax would be on the transferor, or, if such
transfer is through an agent (which person includes a broker, nominee or
middleman) for a disqualified organization, on the agent; (iii) that the person
otherwise liable for the tax shall be relieved of liability for the tax if the
transferee furnishes to such person an affidavit that the transferee is not a
disqualified organization and, at the time of transfer, such person does not
have actual knowledge that the affidavit is false; and (iv) that the Residual
Bonds may be "noneconomic residual interests" within the meaning of Treasury
regulation section 1.860E-1(c)(2) and that the transferor of an ownership
interest in a "noneconomic residual interest" will remain liable for any taxes
due with respect to the income on such residual interest, unless no significant
purpose of the transfer is to enable the transferor to impede the assessment or
collection of tax.

         4.      That the Owner is aware of the tax imposed on a "pass-through
entity" holding the Residual Bonds if at any time during the taxable year of
the pass-through entity a disqualified organization is the record holder of an
interest in such entity.  For this purpose, a "pass-through entity" includes a
regulated investment company, a real estate investment trust or common trust
fund, a partnership, trust or estate, and certain cooperatives.

         5.      That the Owner is aware that the Trustee will not register the
transfer of any Residual Bonds unless the transferee, or the transferee's
agent, delivers to the Indenture Trustee, among other things, an affidavit in
substantially the same form as this affidavit.  The Owner expressly agrees that
it will not consummate any such transfer if it knows or believes that any of
the representations contained in such affidavit and agreement are false.

         6.      That the Owner consents to any additional restrictions or
arrangements that shall be deemed necessary upon advice of counsel to
constitute a reasonable arrangement to ensure that the Residual Bonds will only
be owned, directly or indirectly, by Owners that are Permitted Transferees.

         7.      That the Owner's taxpayer identification number is
_______________.

         8.      That the Owner has reviewed the restrictions set forth on the
face of the Residual Bonds and the provisions of Section 2.15 of the Indenture
under which the Residual Bonds were issued (and, in particular, the Owner is
aware that such Section authorizes the Indenture Trustee to deliver payments to
a person other than the Owner and negotiate a mandatory sale by the Indenture
Trustee in the event that the Owner holds such Residual Bonds in violation of
Section 3); and that the Owner expressly agrees to be bound by and to comply
with such restrictions and provisions.

         9.      That the Owner is not acquiring and will not transfer the
Residual Bonds in order to impede the assessment or collection of any tax.

         10.     That the Owner anticipates that it will, so long as it holds
the Residual Bonds, have sufficient assets to pay any taxes owed by the holder
of such Residual Bonds.

<PAGE>   132
         11.     That the Owner has no present knowledge that it may become
insolvent or subject to a bankruptcy proceeding for so long as it holds the
Residual Bonds.

         12.     That the Owner has no present knowledge or expectation that it
will be unable to pay any United States taxes owed by it so long as any of the
Residual Bonds remain outstanding.  In this regard, the Owner hereby represents
to and for the benefit of the Person from whom it acquired the Residual Bonds
that the Owner intends to pay taxes associated with holding the Residual Bonds
as they become due, fully understanding that it may incur tax liabilities in
excess of any cash flows generated by the Residual Bonds.

         13.     That the Owner is not acquiring the Residual Bonds with the
intent to transfer such Bonds to any person or entity that will not have
sufficient assets to pay any taxes owed by the holder of such Bonds, or that
may become insolvent or subject to a bankruptcy proceeding, for so long as such
Residual Bonds remain outstanding.

         14.     That Owner will, in connection with any transfer that it makes
of any of the Residual Bonds, obtain from its transferee the representations
required by Section 2.15 of the Indenture under which the Residual Bonds were
issued and will not consummate any such transfer if it knows, or knows facts
that should lead it to believe, that any such representations are false.

         15.     That Owner will, in connection with any transfer that it makes
of any of the Residual Bonds, represent and warrant that it is not transferring
the Residual Bonds to impede the assessment or collection of any tax and that
it has no actual knowledge that the proposed transferee:  (i) has insufficient
assets to pay any taxes owed by such transferee as holder of the Residual
Bonds; (ii) may become insolvent or subject to a bankruptcy proceeding, for so
long as the Residual Bonds remain outstanding; and (iii) is not a "Permitted
Transferee."

         16.     That the Owner is a United States Person.

         17.     That the Owner is not an employee benefit plan subject to the
Employee Retirement Income Security Act of 1974, as amended ("ERISA"), or the
Code, nor a Person acting, directly or indirectly, on behalf of any such plan,
and understands that registration of transfer of any Security to any such
employee benefit plan, or to any person acting on behalf of such plan, will not
be made unless such employee benefit plan delivers a certification of facts and
an opinion of its counsel, addressed and satisfactory to the Indenture Trustee
and the Issuer to the effect that such transfer will not (a) cause the assets
of the Trust Estate to be treated as "plan assets" within the meaning of
Department of Labor regulations set forth in 29 C.F.R. Section  2510.3-101, (b)
give rise to any fiduciary duty under ERISA on the part of the Issuer or the
Indenture Trustee, or (c) be treated as, or result in, a prohibited transaction
under Section 406 or 407 of ERISA or Section 4975 of the Code.

                         CMC Securities Corporation III
               Collateralized Mortgage Obligations, Series 1998-1

Ladies and Gentlemen:

       In connection with the sale by ____________________ (the "Transferor")
to ____________________ (the "Transferee") of $_____________ initial Class
Current Principal Balance of Collateralized Mortgage Obligations, Series 1998-
1, Class __________, (the "Private Bonds"), issued pursuant to the Indenture
(the "Indenture") dated March 1, 1998 and the Series 1998-1 Supplement (the
"Series Supplement") thereto dated March 31, 1998, each between CMC Securities
Corporation III, as Issuer (the "Issuer"), and The First National Bank of
Chicago, as Trustee.  Capitalized terms used herein and not otherwise defined
shall have the meanings assigned thereto in the Indenture or the Series
Supplement, as applicable.

       In connection with such acquisition, the Transferee hereby certifies and
agrees:

              1.     The Transferee is acquiring the Private Bonds either (a)
       for its own account or for accounts for which it exercises sole
       investment discretion and not with a view to or for sale in connection
       with any distribution thereof, subject nevertheless to any requirement
       of law that the disposition of the Transferee's property shall at all
       times be and remain within its control, or (b) for resale to "Qualified
       Institutional Buyers" within the meaning of Rule 144A under the 1933 Act
       or an "accredited investor" of the type specified in Rule 3a-7(a)(2)(i)
       of the Investment Company Act of 1940, as amended (the "1940 Act") and
       in accordance with the provisions of the Indenture and the Series
       Supplement.

              2.     The Transferee has received, and has had an opportunity to
       review, (a) a copy of the Private Placement Memorandum dated March 30,
       1998 relating to the Private Bonds
<PAGE>   135
       (the "Memorandum"), (b) a copy of the Indenture and the Series
       Supplement and (c) such other information concerning the Private Bonds,
       the Trust and the Issuer as has been requested by the Transferee and is
       relevant to the Transferee's decision to purchase the Private Bonds.
       The Transferee has had any questions arising from such review answered
       by the Issuer to the satisfaction of the Transferee.  If the Transferee
       did not acquire the Private Bonds from the Transferor in connection with
       the initial distribution of the Private Bonds and was provided with a
       copy of the Memorandum related to the original sale (the "Original
       Sale") of the Private Bonds by the Issuer, the Transferee acknowledges
       that such Memorandum was provided to it by the Transferor, that the
       Memorandum was prepared by the Issuer solely for use in connection with
       the Original Sale and neither the Issuer nor any of its affiliates
       participated in or facilitated in any way the acquisition of the Private
       Bonds by the Transferee from the Transferor, and the Transferee agrees
       that it will look solely to the Transferor and not to the Issuer or any
       of its affiliates with respect to any damage, liability, claim or
       expense arising out of, resulting from or in connection with (i) any
       error or omission, or alleged error or omission, contained in the
       Memorandum or (ii) any information, development or event arising after
       the date of the Memorandum.

              3.     The Transferee is an "accredited investor" of the type
       specified in Rule 3a-7(a)(2)(i) under the 1940 Act, and has such
       expertise, knowledge and sophistication in financial and business
       matters generally, and in financial and business matters related to
       securities similar to the Private Bonds in particular, as to be capable
       of evaluating the merits and risks of an investment in the Private
       Bonds.  The Transferee (or any account referred to above) is able to
       bear the economic risks of such an investment.

              4.     The Transferee will comply with all applicable federal and
       state securities laws in connection with any subsequent resale of the
       Private Bonds by the Transferee.

              5.     The Transferee understands that (a) the Private Bonds have
       not been and will not be registered under the Securities Act of 1933, as
       amended (the "1933 Act"), (b) the Issuer is not required to so register
       the Private Bonds, (c) the Private Bonds may be resold only if
       registered pursuant to the provisions of the 1933 Act, or if an
       exemption from such registration is available, (d) the Private Bonds may
       not be resold if such transfer would result in the registration of the
       Issuer as an "investment company" under the 1940 Act, (e) the Agreement
       contains restrictions regarding the transfer of the Private Bonds, (f)
       the Private Bonds will bear a legend to the foregoing effect and (g) a
       stop order may be placed in the Bond Register relating to the Private
       Bonds against the transfer of any Bond subject to compliance with the
       1933 Act, the rules and regulation thereunder and state securities laws.

              6.     The Transferee is not an employee benefit plan subject to
       the Employee Retirement Income Security Act of 1974, as amended
       ("ERISA"), or the Internal Revenue Code of 1986, as amended (the "Code")
       (a "Plan") a Person acting on behalf of a Plan or a Person using the
       assets of a Plan (each, a "Plan Investor"), or, in the case of an
       insurance





                                      -2-
<PAGE>   136
       company, is either not a Plan Investor or is eligible for an exemption
       from the applicable prohibited transaction provisions of ERISA and the
       Code, or (ii) has attached hereto or delivered to the Trustee an opinion
       of counsel satisfactory to the Trustee and the Issuer to the effect that
       the purchase and holding of such Private Bonds will not constitute or
       result in a prohibited transaction under ERISA or the Code and will not
       (a) cause the assets of the Trust Estate to be treated as "plan assets"
       within the meaning of Department of Labor regulations set forth in 29
       C.F.R. Section  2510.3-101, (b) give rise to any fiduciary duty under
       ERISA on the part of the Issuer, the master servicers, the certificate
       trustee, the Trustee or their respective affiliates or (c) be treated
       as, or result in, a prohibited transaction under Sections 406 or 407 of
       ERISA or Section 4975 of the Code.

              7.     The Transferee will not nor has it authorized or will it
       authorize any person to (a) offer, pledge, sell, dispose of or otherwise
       transfer any Bond, any interest in any Bond or any other similar
       security to any person in any manner, (b) solicit any offer to buy or to
       accept a pledge, disposition or other transfer of any Bond, any interest
       in any Bond or any other similar security from any person in any manner,
       (c) otherwise approach or negotiate with respect to any Bond, any
       interest in any Bond or any other similar security with any person in
       any manner, (d) make any general solicitation by means of general
       advertising or in any other manner, or (e) take any other action, that
       (as to any of (a) through (e) above) would constitute a distribution of
       any Bond under the 1933 Act, that would render the disposition of any
       Bond a violation of Section 5 of the 1933 Act or any state securities
       laws, that would result in the registration of the Issuer as an
       "investment company" under the 1940 Act, or that would require
       registration or qualification pursuant thereto.  The Transferee will not
       sell or otherwise transfer any of the Private Bonds, except in
       compliance with the provisions of the Agreement.  Without limiting the
       generality of the foregoing sentence, if the Transferee sells any of the
       Private Bonds, the Transferee will comply with any applicable
       requirements set forth in, and will obtain from any purchaser any
       representations required pursuant to, Section 2.15 of the Indenture.



                                   Very truly yours,

              1.     The Transferee warrants and represents to, and covenants
with, the Transferor, the Indenture Trustee and the Issuer pursuant to Section

              have not been registered under the Securities Act of 1933, as
              amended (the "1933 Act") or the securities laws of any state.

                     b.     The Transferee considers itself a substantial,
              sophisticated institutional investor having such knowledge and

              of evaluating the merits and risks of investment in the Rule 144A
              Bonds.

                     c.     The Transferee has been furnished with all
              information regarding the Rule 144A Bonds that it has requested
              from the Transferor and the Indenture Trustee.

                     d.     Neither the Transferee nor anyone acting on its

              advertising or in any other manner, or taken any other action.
              that would constitute a distribution of the Rule 144A Bonds under
              the 1933 Act or that would render the disposition of the Rule
              144A Bonds a violation of Section 5 of the 1933 Act or require
              registration pursuant thereto, nor will it act, nor has it
              authorized or will it authorize any person to act, in such manner
              with respect to the Rule 144A Bonds.

              attached hereto as Annex 1 or Annex 2. The Transferee is aware
              that the sale to it is being made in reliance on Rule 144A.  The

              transferred only (i) to a person reasonably believed to be a

              or for the account of a qualified institutional buyer to whom
              notice is given that the resale, pledge or transfer is being made
              in reliance on Rule 144A, or (ii) pursuant to another exemption
              from registration under the 1933 Act.

       [3].   The Transferee is not an employee benefit plan subject to the
Employee Retirement Income Security Act of 1974, as amended ("ERISA"), or the
Internal Revenue Code of 1986, as amended (the "Code") (a "Plan"), a Person

transaction provisions of ERISA and the Code, or (ii) has attached hereto or

Transferee used the cost of such securities to the Transferee and did not
include any of the securities referred to in the preceding paragraph.  Further,
in determining such aggregate amount, the Transferee may have included
securities owned





                            ANNEX 1 to EXHIBIT C-3-2
<PAGE>   144
by subsidiaries of the Transferee, but only if such subsidiaries are
consolidated with the Transferee in its financial statements prepared in
accordance with generally accepted accounting principles and if the investments
of such subsidiaries are managed under the Transferee's direction.  However,
such securities were not included if the Transferee is a majority-owned,
consolidated subsidiary of another enterprise and the Transferee is not itself
a reporting company under the Securities Exchange Act of 1934.

       5.     The Transferee acknowledges that it is familiar with Rule 144A
and understands that the seller to it and other parties related to the Bonds
are relying and will continue to rely on the statements made herein because one
or more sales to the Transferee may be in reliance on Rule 144A.

       6.     Will the Transferee be purchasing the Rule 144A Bonds only for
the Transferee's own account?

                              Yes _____  No _____.

       If the answer to the foregoing question is "no", the Transferee agrees
that, in connection with any purchase of securities sold to the Transferee for
the account of a third party (including any separate account) in reliance on
Rule 144A, the Transferee will only purchase for the account of a third party
that at the time is a "qualified institutional buyer" within the meaning of
Rule 144A.  In addition, the Transferee agrees that the Transferee will not
purchase securities for a third party unless the Transferee has obtained a
current representation letter from such third party or taken other appropriate
steps contemplated by Rule 144A to conclude that such third party independently
meets the definition of "qualified institutional buyer" set forth in Rule 144A.

       23.    The Transferee will notify each of the parties to which this
certification is made of any changes in the information and conclusions herein
during the period between the date of this certification and the date the
Transferee purchases the Rule 144A Bonds.  Unless such notice is given, the
Transferee's purchase of the Rule 144A Bonds will constitute a reaffirmation of
this certification as of the date of such purchase.

                       CMC Securities Corporation III
             Collateralized Mortgage Obligations, Series 1998-1

Dear Sirs:

        This letter is delivered to you in connection with the sale by
_____________________ (the "Transferor") to
___________________________________________ (the "Purchaser") of the
Collateralized Mortgage Obligations, Series 1998-1, Class [R-1][Class
R-2][Class R-3] (the "Residual Bonds"), issued pursuant to the Indenture (the
"Indenture") dated as of March 1, 1998 and the Series 1998-1 Supplement, dated
as of March 31, 1998, each between CMC Securities Corporation III, as Issuer
(the "Issuer"), and The First National Bank of Chicago, as Trustee (the
"Indenture Trustee").  All terms used herein and not otherwise defined shall
have the meaning set forth in the Indenture for the Series Supplement, as
applicable.

        The Transferor hereby certifies, represents and warrants to, and
covenants with, the Issuer and the Indenture Trustee that:

        1.      No purpose of the Transferor relating to the sale of the
Residual Bonds by the Transferor to the Purchaser is or will be to impede the
assessment or collection of any tax.

        2.      The Transferor understands that the Purchaser has delivered to
the Indenture Trustee a transferee affidavit and agreement in the form attached
to the Series Supplement as Exhibit B.  The Transferor does not know or believe
that any representation contained therein is false.

        3.      The Transferor has at the time of the transfer conducted a
reasonable investigation of the financial condition of the Purchaser as
contemplated by Treasury Regulations Section 1.860E-1(c)(4)(i) and, as a result
of that investigation, the Transferor has determined that the Purchaser has
historically paid its debts as they have become due and has found no
significant 



<PAGE>   149

evidence to indicate that the Purchaser will not continue to pay its debts as
they become due in the future.  The Transferor understands that the transfer of
the Residual Bonds may not be respected for United States income tax purposes
(and the Transferor may continue to be liable for United States income taxes
associated therewith) unless the Transferor has conducted such an
investigation.

        4.      The Transferor has no actual knowledge that the proposed
Transferee is a Disqualified Organization, an agent of a Disqualified
Organization or a Non-U.S. Person.


                              Very truly yours,


                              -----------------------------------

be maintained pursuant to Section 3.07, without regard to whether or not such
policy is maintained.

       Voluntary Principal Prepayment:  With respect to any Prepayment Period,
any Principal Prepayment received from the related Mortgagor on a Mortgage
Loan.


                                   ARTICLE II
                          CONVEYANCE OF MORTGAGE LOANS

       Section 2.01.  Conveyance of Mortgage Loans to Certificate Trustee.

       (a)    Three trusts (each, a "Trust") of which the Certificate Trustee
is the trustee are hereby created under the laws of the State of New York for
the benefit of the Holders of the related Series of Certificates.  The purpose
of each Trust is to hold the related Trust Fund and provide for the issuance,
execution, authentication and delivery of the related Certificates.  The assets
of each Trust shall consist of the related Trust Fund.  Each Trust shall be
irrevocable.

       The assets of each Trust shall remain in the custody of the Custodian on
behalf of the Certificate Trustee, on behalf of the related Trust, and shall be
kept in the related Trust.  Moneys to the credit of each Trust shall be held by
the Certificate Trustee and invested as provided herein.  All assets received
and held in each Trust will not be subject to any right, charge, security
interest, lien





                                       18

or claim of any kind in favor of The First National Bank of Chicago in its own
right, or any Person claiming through it.  The Certificate Trustee, on behalf
of each Trust, shall not have the power or authority to transfer, assign,
hypothecate, pledge or otherwise dispose of any of the assets of such Trust to
any Person, except as permitted herein.  No creditor of a beneficiary of a
Trust, of the Certificate Trustee, of a Master Servicer, or of the Depositor
shall have any right to obtain possession of, or otherwise exercise legal or
equitable remedies with respect to, the property of a Trust, except in
accordance with the terms of this Agreement.

       (b)    The Depositor concurrently with the execution and delivery of
this Agreement, sells, transfers and assigns to the Certificate Trustee,
without recourse, all its right, title and interest in and to the Trust Funds,
including but not limited to:

              (i)    the related Mortgage Loans and all rights pertaining
       thereto including all interest and principal due with respect to such
       Mortgage Loans after the Cut-off Date, but excluding any payments of
       principal or interest due on or prior to the Cut-off Date;

              (ii)   such assets as shall from time to time be credited, or are
       required by the terms of this Agreement to be credited, to the
       Certificate Account,

              (iii)  such assets relating to the Mortgage Loans as from time to
       time may be held by a Master Servicer in Protected Accounts (excluding
       any income to such Master Servicer from Permitted Investments under
       Section 4.01(a)) or in Buydown Fund Accounts;

              (iv)   any Servicing Accounts (to the extent the mortgagee has a
       claim thereto and excluding any income to the applicable Master Servicer
       or interest payable to Mortgagors pursuant to applicable law);

              (v)    any REO Property;

              (vi)   the Required Insurance Policies and any amounts paid or
       payable by the insurer under any Insurance Policy (to the extent the
       mortgagee has a claim thereto);

              (vii)  the Mortgage Loan Purchase Agreement to the extent
       provided in Section 2.04(a); and

              (viii) any proceeds of the foregoing.

Although it is the intent of the parties to this Agreement that the conveyance
of the Depositor's right, title and interest in and to the Mortgage Loans and
other assets in the Trust Funds pursuant to this Agreement shall constitute a
purchase and sale and not a loan, in the event that such conveyance is deemed
to be a loan, it is the intent of the parties to this Agreement that the
Depositor shall be deemed to have granted to the Certificate Trustee a first
priority perfected security interest in all of the Depositor's right, title and
interest in, to and under the Mortgage Loans and other assets in the Trust
Funds, and that this Agreement shall constitute a security agreement under
applicable law.





                                       19
<PAGE>   24
       (c)    In connection with the above transfer and assignment, the
Depositor hereby deposits with the Custodian on behalf of the Certificate
Trustee, with respect to each Mortgage Loan (i) the original Mortgage Note,
endorsed without recourse to the order of the Certificate Trustee and showing
an unbroken chain of endorsements from the original payee thereof to the Person
endorsing it to the Certificate Trustee, (ii) the original Security Instrument,
which shall have been recorded, with evidence of such recording indicated
thereon, (iii) a certified copy of the assignment (which may be in the form of
a blanket assignment if permitted in the jurisdiction in which the Mortgaged
Property is located) to the Certificate Trustee of the Security Instrument,
with evidence of recording with respect to each Mortgage Loan in the name of
the Certificate Trustee thereon (or if (vii) below applies, shall be in
recordable form), (iv) all intervening assignments of the Security Instrument,
if applicable and only to the extent available to the Depositor with evidence
of recording thereon, (v) the original or a copy of the policy or certificate
of primary mortgage guaranty insurance, to the extent available, if any, (vi)
the original policy of title insurance or mortgagee's certificate of title
insurance or commitment or binder for title insurance, (vii) the originals of
each assumption, modification or substitution agreement, if any, relating to
the Mortgage Loan, and (viii) the certificate of primary mortgage insurance, if
applicable; provided, however, that in lieu of the foregoing, the Depositor may
deliver the following documents, under the circumstances set forth below:

              (A)    in lieu of the original Security Instrument, assignments
       to the Certificate Trustee or intervening assignments thereof which have
       been delivered, are being delivered or will, upon receipt of recording
       information relating to the Security Instrument required to be included
       thereon, be delivered to recording offices for recording and have not
       been returned to the Depositor in time to permit their delivery as
       specified above, the Depositor may deliver a true copy thereof with a
       certification by BSMCC or the applicable Master Servicer, on the face of
       such copy, substantially as follows:  "Certified to be a true and
       correct copy of the original, which has been transmitted for recording";

              (B)    in lieu of the Security Instrument, assignment to the
       Certificate Trustee or intervening assignments thereof, if the
       applicable jurisdiction retains the originals of such documents (as
       evidenced by a certification from BSMCC or the applicable Master
       Servicer to such effect) the Depositor may deliver photocopies of such
       documents containing an original certification by the judicial or other
       governmental authority of the jurisdiction where such documents were
       recorded; and

              (C) in lieu of the original Mortgage Notes relating to five BA
       Mortgage Loans and six Cendant Mortgage Loans, with an aggregate
       Scheduled Principal Balance as of the Cut-off Date of $3,953,828.96,
       each as identified in the list delivered by the Depositor to the
       Certificate Trustee on the Closing Date and set forth in Exhibit J
       hereto, the Depositor may deliver a lost note affidavit and, if
       available, a copy of the original Mortgage Note;

and provided further, however, that in the case of Mortgage Loans which have
been prepaid in full after the Cut-off Date and prior to the Closing Date, the
Depositor, in lieu of delivering the above documents, may deliver to the
Custodian and to the Certificate Trustee a certification of a Servicing Officer
to such effect and shall deposit all amounts paid in respect of such Mortgage
Loans in the





                                       20
<PAGE>   25
Certificate Account on the Closing Date.  The Depositor shall deliver such
original documents (including any original documents as to which certified
copies had previously been delivered) to the Custodian on behalf of the
Certificate Trustee promptly after they are received.  As to each Mortgage Loan
master serviced by it, the applicable Master Servicer shall cause, at its
expense, the Security Instrument and intervening assignments, if any, and the
assignment of the Security Instrument to the Certificate Trustee to be recorded
not later than one year after the Closing Date.

       Section 2.02.  Acceptance of Mortgage Loans by Certificate Trustee.

       (a)    The Certificate Trustee acknowledges receipt of, subject to
further review and the exceptions which may be noted pursuant to the procedures
described below, and declares that the Custodian holds on behalf of the
Certificate Trustee the documents (or certified copies thereof) delivered to it
pursuant to Section 2.01 and declares that the Custodian on behalf of the
Certificate Trustee will continue to hold those documents and any amendments,
replacements or supplements thereto and all other assets of each Trust Fund
delivered to it as Certificate Trustee or to the Custodian in trust for the use
and benefit of all present and future Holders of the Certificates.  No later
than 45 days after the Closing Date (or, with respect to any Substitute
Mortgage Loan, within five Business Days after the receipt thereof by the
Custodian on behalf of the Certificate Trustee), the Certificate Trustee
agrees, for the benefit of the Certificateholders, to cause the Custodian to
review each Mortgage File delivered to it and to execute and deliver, or cause
to be executed and delivered, to the Depositor and the applicable Master
Servicer an Initial Certification substantially in the form annexed hereto as
Exhibit G.  In conducting such review, the Certificate Trustee will cause the
Custodian to ascertain whether all required documents have been executed and
received and whether those documents relate, determined on the basis of the
Mortgagor name, original principal balance and loan number, to the Mortgage
Loans it has received, as identified in the related Mortgage Loan Schedule
(provided, however, that with respect to those documents described in
subclauses (c)(iv), (c)(v) and (c)(vi) of Section 2.01, the Custodian's
obligations shall extend only to documents actually delivered pursuant to such
subsections).  In performing any such review, the Custodian may conclusively
rely on the purported due execution and genuineness of any such document and on
the purported genuineness of any signature thereon.  If the Custodian finds any
document constituting part of the Mortgage File not to have been executed or
received, or to be unrelated to the Mortgage Loans identified in the related
Mortgage Loan Schedule or to appear to be defective on its face, the Custodian
shall promptly notify BSMCC.  BSMCC shall correct or cure any such defect
within 90 days from the date of notice from the Custodian of the defect and if
BSMCC fails to correct or cure the defect within such period, and such defect
materially and adversely affects the interests of the Certificateholders in the
related Mortgage Loan, BSMCC will, subject to Section 2.05, within 120 days
from the Certificate Trustee's notification purchase such Mortgage Loan at the
Repurchase Price; provided, however, that if such defect relates solely to the
inability of BSMCC to deliver the original Security Instrument or intervening
assignments thereof, or a certified copy, because the originals of such
documents, or a certified copy, have not been returned by the applicable
jurisdiction, BSMCC shall not be required to purchase such Mortgage Loan if
BSMCC delivers such original documents or certified copy promptly upon receipt,
but in no event later than 360 days after the Closing Date.  The foregoing
repurchase obligation shall not apply in the event that BSMCC cannot deliver
such original or copy of any document submitted for recording to the
appropriate recording office in the applicable jurisdiction because such
document





                                       21
<PAGE>   26
has not been returned by such office; provided further, however,  that BSMCC
shall instead deliver a recording receipt of such recording office or, if such
receipt is not available, a certificate of a Servicing Officer confirming that
such documents have been accepted for recording, and delivery to the Custodian
shall be effected by BSMCC within 30 days after its receipt of the original
recorded document.

       (b)    No later than one year after the Closing Date, the Certificate
Trustee will cause the Custodian to review, for the benefit of the
Certificateholders, the Mortgage Files delivered to it and will execute and
deliver or cause to be executed and delivered to the Depositor and each Master
Servicer, a Final Certification substantially in the form annexed hereto as
Exhibit H.  In conducting such review, the Certificate Trustee will cause the
Custodian to ascertain whether an original of each document required to be
recorded has been returned from the recording office with evidence of recording
thereon or a certified copy has been obtained from the recording office.  If
the Custodian finds that any document constituting part of the Mortgage File
has not been received, or is unrelated, determined on the basis of the
Mortgagor name, original principal balance and loan number, to the Mortgage
Loans identified in the related Mortgage Loan Schedule or appears defective on
its face, the Custodian shall promptly notify BSMCC (provided, however, that
with respect to those documents described in subsection (c)(iv), (c)(v) and
(c)(vi) of Section 2.01, the Custodian's obligations shall extend only to the
documents actually delivered pursuant to such subsections).  BSMCC shall
correct or cure any such defect or shall deliver to the Certificate Trustee and
the Custodian an Opinion of Counsel to the effect that such defect does not
materially or adversely affect the interests of Certificateholders in such
Mortgage Loan within 90 days after the date of notice from the Certificate
Trustee of the defect, and if BSMCC is unable to cure such defect or deliver
such Opinion of Counsel within such period, and if such defect materially and
adversely affects the interests of the Certificateholders in the related
Mortgage Loan, BSMCC shall, subject to Section 2.05, within 120 days after the
Certificate Trustee's notification purchase such Mortgage Loan at the
Repurchase Price; provided, however, that if such defect relates solely to the
inability of BSMCC to deliver the original Security Instrument or intervening
assignments thereof, or a certified copy, because the originals of such
documents, or a certified copy, have not been returned by the applicable
jurisdiction, BSMCC shall not be required to purchase such Mortgage Loan, if
BSMCC delivers such original documents or certified copy promptly upon receipt,
but in no event later than 360 days after the Closing Date.

       (c)    Notwithstanding the foregoing and the provisions of Section 2.04,
if a Mortgage Loan is discovered to have a defect which, had such defect been
discovered before the Startup Day, would have prevented the Mortgage Loan from
being a "qualified mortgage" within the meaning of Section 860G(a)(3) of the
Code, BSMCC shall, within 90 days after the date such defect is discovered,
purchase such Mortgage Loan at the applicable Repurchase Price, unless BSMCC
delivers to the Certificate Trustee an Opinion of Counsel to the effect that
continuing to hold such Mortgage Loan will not adversely affect the status of
each of REMIC I, REMIC II and REMIC III as a REMIC for federal income tax
purposes.

       (d)    In the event that a Mortgage Loan is purchased by BSMCC in
accordance with Subsections 2.02(a), (b) or (c) above, BSMCC shall provide the
Repurchase Price to the Certificate Trustee for deposit in the Certificate
Account and shall provide to the Certificate Trustee written





                                       22
<PAGE>   27
notification detailing the components of the Repurchase Price.  Upon deposit of
the Repurchase Price in the Certificate Account, the Certificate Trustee shall
cause the Custodian to release to BSMCC the related Mortgage File and shall
execute and deliver all instruments of transfer or assignment, without
recourse, furnished to it by BSMCC as are necessary to vest in BSMCC title to
and rights under the Mortgage Loan.  Such purchase shall be deemed to have
occurred on the date on which the Repurchase Price in available funds is
received by the Certificate Trustee.  The Certificate Trustee shall amend the
applicable Mortgage Loan Schedule, which was previously delivered to it by the
Depositor in a form agreed to between the Depositor and the Certificate
Trustee, to reflect such repurchase and shall promptly notify the applicable
Master Servicer and the Rating Agencies of such amendment.  The obligation of
BSMCC to repurchase (or substitute a Substitute Mortgage Loan, pursuant to
Section 2.04, for) any Mortgage Loan as to which such a defect in a constituent
document exists shall be the sole remedy respecting such defect available to
the Certificateholders or to the Certificate Trustee on their behalf.

       Section 2.03.  Representations, Warranties and Covenants of the Master
Servicers.

       (a)    Each Master Servicer hereby represents and warrants to the
Certificate Trustee as of the Closing Date that:

              (i)  (A) in the case of BAFSB, it is a federal savings bank duly
       organized, validly existing and in good standing under the laws of the
       United States of America and throughout the term of this Agreement will
       remain a federal savings bank duly organized, validly existing and in
       good standing under the laws of the United States of America, and (B) in
       the case of Cendant, it is a corporation duly organized, validly
       existing and in good standing under the laws of the State of New Jersey
       and is in compliance with the laws of each State in which a Mortgaged
       Property related to a Cendant Mortgage Loan is located to the extent
       necessary to enable it to perform its obligations hereunder and is in
       good standing as a foreign corporation in each jurisdiction in which the
       nature of its business or the properties owned or leased by it make such
       qualification necessary, except where any failure to qualify would not
       have a material adverse effect on Cendant, the Trusts, the Certificates
       or the Certificateholders, and throughout the term of this Agreement
       will remain a corporation duly organized, validly existing and in good
       standing under the laws of the State of New Jersey and in compliance
       with the laws of such states and in good standing as a foreign
       corporation in each such jurisdiction; and in the case of each Master
       Servicer, it has the corporate power and authority to perform its
       obligations under this Agreement;

              (ii)  The execution and delivery of this Agreement have been duly
       authorized by all requisite corporate action;

              (iii)  This Agreement, assuming due authorization, execution, and
       delivery by the other parties hereto, will constitute its legal, valid
       and binding obligation, enforceable in accordance with its terms, except
       only as such enforcement may be limited by applicable Debtor Relief Laws
       and that certain equitable remedies may not be available regardless of
       whether enforcement is sought in equity or at law;





                                       23
<PAGE>   28
              (iv)  Its execution and delivery of this Agreement and its
       performance and compliance with the terms of this Agreement will not (A)
       violate its charter or articles of incorporation, as applicable, or
       bylaws (B) to its knowledge, violate any law or regulation, or any
       administrative or judicial decree or order to which it is subject or (C)
       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 contract, agreement or other instrument to which it is a
       party or which may be applicable to it or any of its assets;

              (v)  To its best knowledge, after reasonable investigation, it is
       not in default with respect to any order or decree of any court or any
       order, regulation or demand of any federal, state, municipal or
       governmental agency, which default would reasonably be expected to have
       consequences that would materially and adversely affect its financial
       condition or operations or its performance hereunder;

              (vi)  It does not believe, nor does it have any reason or cause
       to believe, that it cannot perform each and every covenant contained in
       this Agreement to be performed by it;

              (vii)  The consummation of the transactions contemplated by this
       Agreement is in the ordinary course of its business; and

              (viii)  No litigation is pending or, to its best knowledge,
       threatened against it, which could be reasonably expected to materially
       and adversely affect its entering into this Agreement or performing its
       obligations under this Agreement or which would have a material adverse
       effect on its financial condition.

       Section 2.04  Assignment of Interest in the Mortgage Loan Purchase
Agreement.

       (a)    The Depositor hereby assigns to the Certificate Trustee all of
its right, title and interest in the Mortgage Loan Purchase Agreement and the
Assignment Agreement, provided that the Depositor retains a joint and several
right in the event of breach of the representations, warranties and covenants
of BSMCC under the Mortgage Loan Purchase Agreement, to enforce the provisions
thereof and to seek all or any available remedies; and provided further that
this shall not be deemed an agreement or requirement on the part of the
Depositor to pursue any such remedies; provided, further, that the obligations
of BSMCC to substitute or repurchase a Mortgage Loan shall be the Certificate
Trustee's and the Certificateholders' sole remedy for any breach thereof.  At
the request of the Certificate Trustee, the Depositor shall take such actions
as may be necessary to enforce the above right, title and interest on behalf of
the Certificate Trustee and the Certificateholders or shall execute such
further documents as the Certificate Trustee may reasonably require in order to
enable the Certificate Trustee to carry out such enforcement.

       (b)    If the Depositor, a Master Servicer, the Custodian or the
Certificate Trustee discovers a breach of any of the representations and
warranties set forth in Exhibit C and such breach existed on the date the
representation and warranty was made, which breach materially and adversely
affects the value of the interests of Certificateholders or the Certificate
Trustee in the related Mortgage Loan, the party discovering the breach shall
give prompt written notice of the breach to BSMCC and





                                       24
<PAGE>   29
the other parties.  Within 90 days after its discovery or receipt of notice
that such breach has occurred (whichever occurs earlier), BSMCC will cure the
breach in all material respects or, subject to Section 2.05, will purchase the
Mortgage Loan or any property acquired with respect thereto from the
Certificate Trustee; provided, however, that if there is a breach of any
representation set forth in Exhibit C and the Mortgage Loan or the related
property acquired with respect thereto has been sold, then BSMCC will pay, in
lieu of the Repurchase Price, any excess of the Repurchase Price over the Net
Liquidation Proceeds received upon such sale.  (If the Net Liquidation Proceeds
exceed the Repurchase Price, any excess shall be paid to BSMCC to the extent
not required by law to be paid to the borrower.)  Any such purchase by BSMCC
shall be made by providing an amount equal to the Repurchase Price to the
Certificate Trustee for deposit in the Certificate Account and the Certificate
Trustee, upon deposit of the Repurchase Price in the Certificate Account and of
written notification detailing the components of such Repurchase Price, shall
cause the Custodian to release to BSMCC the related Mortgage File and shall
execute and deliver all instruments of transfer or assignment furnished to it
by BSMCC, without recourse, as are necessary to vest in BSMCC title to and
rights under the Mortgage Loan or any property acquired with respect thereto.
Such purchase shall be deemed to have occurred on the date on which the
Repurchase Price in available funds is received by the Certificate Trustee.
The Certificate Trustee shall amend the applicable Mortgage Loan Schedule to
reflect such repurchase and shall promptly notify the applicable Master
Servicer, the Custodian and the Rating Agencies of such amendment.  Enforcement
of the obligation of BSMCC, to purchase (or substitute a Substitute Mortgage
Loan, pursuant to Section 2.05, for) any Mortgage Loan or any property acquired
with respect thereto (or pay the Repurchase Price as set forth in the above
proviso) as to which a breach has occurred and is continuing shall constitute
the sole remedy respecting such breach available to the Certificateholders or
the Certificate Trustee on their behalf.

       Section 2.05. Substitution of Mortgage Loans.  Notwithstanding anything
to the contrary in this Agreement, in lieu of purchasing a Mortgage Loan
pursuant to Sections 2.02 or 2.04, BSMCC may, no later than the date by which
such purchase by BSMCC would otherwise be required, tender to the Custodian on
behalf of the Certificate Trustee a Substitute Mortgage Loan accompanied by an
Officer's Certificate of BSMCC that such Substitute Mortgage Loan conforms to
the requirements set forth in the definition of "Substitute Mortgage Loan";
provided, however, that substitution pursuant to this Section 2.05 in lieu of
purchase shall not be permitted after the termination of the two-year period
beginning on the Startup Day.  The Certificate Trustee shall cause the
Custodian to examine the Mortgage File for any Substitute Mortgage Loan in the
manner set forth in Section 2.02(a) and shall notify the related Master
Servicer in writing, within five Business Days after receipt, whether or not
the documents relating to the Substitute Mortgage Loan satisfy the requirements
set forth in Section 2.02(a).  Within two Business Days after such
notification, BSMCC is required to provide to the Certificate Trustee for
deposit in the Certificate Account the amount, if any, by which the Outstanding
Principal Balance as of the next preceding Due Date of the Mortgage Loan for
which substitution is being made, after giving effect to Scheduled Principal
due on such date, exceeds the Outstanding Principal Balance as of such date of
the Substitute Mortgage Loan, after giving effect to Scheduled Principal due on
such date, which amount shall be treated for the purposes of this Agreement as
if it were the payment by BSMCC of the Repurchase Price for the purchase of a
Mortgage Loan by BSMCC.  After such notification to BSMCC and, if any such
excess exists, upon receipt of such deposit, the Certificate Trustee shall
accept such





                                       25
<PAGE>   30
Substitute Mortgage Loan, which shall thereafter be deemed to be a Mortgage
Loan, hereunder.  In the event of such a substitution, accrued interest on the
Substitute Mortgage Loan for the month in which the substitution occurs and any
Principal Prepayments made thereon during such month shall be the property of
the related Trust and accrued interest for such month on the Mortgage Loan for
which the substitution is made and any Principal Prepayments made thereon
during such month shall be the property of BSMCC.  The Scheduled Principal on a
Substitute Mortgage Loan due on the Due Date in the month of substitution shall
be the property of BSMCC and the Scheduled Principal on the Mortgage Loan for
which the substitution is made due on such Due Date shall be the property of
the related Trust.  Upon acceptance of the Substitute Mortgage Loan, the
Certificate Trustee shall cause the Custodian to release to BSMCC the Mortgage
File related to any Mortgage Loan released pursuant to this Section 2.05 and
shall execute and deliver all instruments of transfer or assignment, without
recourse, in form as provided to it as are necessary to vest in BSMCC title to
and rights under any Mortgage Loan released pursuant to this Section 2.05.
BSMCC shall deliver the documents related to the Substitute Mortgage Loan in
accordance with the provisions of Sections 2.01(c) and 2.02(b), with the date
of acceptance of the Substitute Mortgage Loan deemed to be the Closing Date for
purposes of the time periods set forth in those Subsections.  The
representations and warranties set forth in Exhibit C shall be deemed to have
been made by BSMCC with respect to each Substitute Mortgage Loan as of the date
of acceptance of such Mortgage Loan by the Custodian on behalf of the
Certificate Trustee.  The Certificate Trustee shall amend the Mortgage Loan
Schedule to reflect such substitution and shall provide a copy of such amended
Mortgage Loan Schedule to each Master Servicer, the Custodian and the Rating
Agencies.

       Section 2.06.  Representations and Warranties Concerning the Depositor.
The Depositor hereby represents and warrants to the Certificate Trustee and
each Master Servicer as follows:

              (i)  the Depositor (a) is a corporation duly organized, validly
       existing and in good standing under the laws of the State of Delaware
       and (b) is qualified and in good standing as a foreign corporation to do
       business in each jurisdiction where such qualification is necessary,
       except where the failure so to qualify would not reasonably be expected
       to have a material adverse effect on the Depositor's business as
       currently conducted or on the Depositor's ability to enter into this
       Agreement and to consummate the transactions contemplated hereby;

              (ii)  the Depositor has full corporate power to own its property,
       to carry on its business as presently conducted and to enter into and

              (iii)  the execution and delivery by the Depositor of this
       Agreement have been duly authorized by all necessary corporate action on
       the part of the Depositor; and neither the execution and delivery of
       this Agreement, nor the consummation of the transactions herein
       contemplated, nor compliance with the provisions hereof, will conflict
       with or result in a breach of, or constitute a default under, any of the
       provisions of any law, governmental rule, regulation, judgment, decree
       or order binding on the Depositor or its properties or the certificate
       of incorporation or by-laws of the Depositor, except those conflicts,
       breaches or defaults which would not reasonably be expected to have a
       material adverse effect on the

       Depositor's ability to enter into this Agreement and to consummate the
       transactions contemplated hereby;

              (iv)  the execution, delivery and performance by the Depositor of

       to, the registration with, or the taking of any other action in respect
       of, any state, federal or other governmental authority or agency, except
       those consents, approvals, notices, registrations or other actions as
       have already been obtained, given or made;

              (v)  this Agreement has been duly executed and delivered by the
       Depositor and, assuming due authorization, execution and delivery by the
       other parties hereto, constitutes a valid and binding obligation of the
       Depositor enforceable against it in accordance with its terms, except
       only as such enforcement may be limited by applicable Debtor Relief Laws
       and that certain equitable remedies may not be available regardless of
       whether enforcement is sought in equity or at law;

              (vi)  there are no actions, suits or proceedings pending or, to
       the knowledge of the Depositor, threatened against the Depositor, before

       (i) with respect to any of the transactions contemplated by this
       Agreement or (ii) with respect to any other matter which in the
       reasonable judgment of the Depositor will be determined adversely to the
       Depositor and would, if determined adversely to the Depositor,
       materially and adversely affect the Depositor's ability to enter into
       this Agreement or perform its obligations under this Agreement; and the
       Depositor is not in default with respect to any order of any court,
       administrative agency, arbitrator or governmental body so as to
       materially and adversely affect the transactions contemplated by this
       Agreement; and

              (vii)  immediately prior to the transfer and assignment to the
       Certificate Trustee, each Mortgage Note and each Mortgage were not
       subject to an assignment or pledge, and the Depositor had good and
       marketable title to and was the sole owner thereof and had full right to
       transfer and sell such Mortgage Loan to the Certificate Trustee free and
       clear of any encumbrance, equity, lien, pledge, charge, claim or
       security interest.

       Section 2.07.  The Custodian.  Notwithstanding anything to the contrary
in this Agreement, the parties hereto acknowledge that the functions of the
Certificate Trustee with respect to the acceptance, inspection, custody and
release of the Mortgage Files pursuant to Article II shall be performed by the
Custodian.  The Custodian shall receive no separate fee for performing such
services.  The Certificate Trustee shall not be liable for any acts or
omissions of the Custodian.  The parties hereto hereby appoint First Chicago
National Processing Corporation, and First Chicago National Processing
Corporation hereby accepts such appointment, to serve as Custodian hereunder.

                                  ARTICLE III
                 ADMINISTRATION AND SERVICING OF MORTGAGE LOANS

       Section 3.01.  Master Servicers to Master Service.

       (a)    Notwithstanding anything contained herein to the contrary, the
parties hereto agree that BAFSB shall be the Master Servicer of the BA Mortgage
Loans and Cendant shall be the Master Servicer of the Cendant Mortgage Loans.
Each Master Servicer shall supervise the servicing and administration of the
Mortgage Loans for which it is the Master Servicer and any related REO Property
in accordance with the terms of this Agreement and its normal servicing
practices, which shall generally conform to the standards of FNMA and shall
have full authority to do anything it reasonably deems appropriate or desirable
in connection with the supervision of such servicing and administration.  Each
Master Servicer may perform its servicing responsibilities hereunder through
other agents or independent contractors, but shall not thereby be released from
any of its responsibilities as hereinafter set forth.  The authority of a
Master Servicer, in its capacity as master servicer, shall include, without
limitation, the power to consult with and advise any sub-servicer regarding
administration of a related Mortgage Loan.  The authority of a Master Servicer
shall include, in addition, the power on behalf of the Certificateholders, the
Certificate Trustee or any of them to (i) execute and deliver customary
consents or waivers and other instruments and documents, (ii) consent to
transfers of any related Mortgaged Property and assumptions of the related
Mortgage Notes and Security Instruments (in the manner provided in this
Agreement) and (iii) collect any Insurance Proceeds and Liquidation Proceeds
with respect to the related Mortgage Loans.  Without limiting the generality of
the foregoing, each Master Servicer may, and is hereby authorized, and
empowered by the Certificate Trustee to, execute and deliver, on behalf of
itself, the Certificateholders, the Certificate Trustee, or any of them, any
instruments of satisfaction, cancellation, partial or full release, discharge
and all other comparable instruments, with respect to the Mortgage Loans for
which such Master Servicer is the master servicer, the related Insurance
Policies and the accounts related thereto, and the related Mortgaged
Properties.  Each Master Servicer may exercise this power in its own name or in
the name of the Certificate Trustee.

       (b)    Notwithstanding the provisions of Subsection 3.01(a), no Master
Servicer shall take any action which, in such Master Servicer's reasonable
business judgment, would be inconsistent with procedures and practices required
by FNMA, with the interest of the Certificate Trustee or the Certificateholders
in the related Mortgage Loans or with the rights and interests of the
Certificate Trustee or the Certificateholders under this Agreement.

       (c)    The Certificate Trustee shall furnish each Master Servicer with
any powers of attorney and other documents in form as provided to it necessary
or appropriate to enable such Master Servicer to service and administer the
related Mortgage Loans and REO Property.

       Section 3.02.  Delivery of Documents to Successor Master Servicers.  In
the event that the Certificate Trustee or its designee as a successor master
servicer for the Certificate Trustee assumes the servicing obligations of a
Master Servicer under Section 8.02, upon the reasonable request of the
Certificate Trustee or such designee as a successor master servicer, such
Master Servicer shall at its own expense deliver to the Certificate Trustee, or
at its written request to such designee, all





                                       28
<PAGE>   33
documents and records, electronic or otherwise in such Master Servicer's
possession, relating to the related Mortgage Loans or REO Property and an
accounting of amounts collected and held by it, if any, and will otherwise
cooperate and use its reasonable best efforts to effect the orderly and
efficient transfer of the master servicing responsibilities hereunder to the
Certificate Trustee, or at its written request to such designee as a successor
master servicer.

       Section 3.03.  Collection of Mortgage Loan Payments.

       (a)    Each Master Servicer shall make its reasonable best efforts to
collect all payments required under the terms and provisions of the related
Mortgage Loans and will follow collection procedures comparable to the
collection procedures of FNMA-approved servicers.  Consistent with the
foregoing, a Master Servicer may in its discretion (i) waive or permit to be
waived any late payment charge or assumption fee and (ii) suspend or
temporarily reduce or permit to be suspended or temporarily reduced Scheduled
Payments for a period of up to six months, or arrange or permit an arrangement
with a Mortgagor for a scheduled liquidation of delinquencies.  In the event a
Master Servicer shall consent to the deferment of the due dates for Scheduled
Payments due on a related Mortgage Note, the related Master Servicer shall make
a Monthly Advance to the same extent as if such installment were due, owing and
delinquent and had not been deferred through liquidation of the Mortgaged
Property; provided, however, that the obligation of the Master Servicer to make
a Monthly Advance shall apply only to the extent that the Master Servicer
believes, in good faith, that such Monthly Advance is not a Nonrecoverable
Advance.

       (b)    A Master Servicer may not make any advances of amounts due in the
future with respect to a Mortgage Loan that it master services and shall not
permit, except as permitted in Section 3.08(a), (i) any modification with
respect to such Mortgage Loan that would change the Mortgage Interest Rate,
reduce or increase the principal balance (except for reductions resulting from
actual payments of principal) or change the final maturity date on such
Mortgage Loan or (ii) any modification, waiver or amendment of any term of such
Mortgage Loan that would both (A) effect an exchange or reissuance of such
Mortgage Loan under Section 1001 of the Code (or final, temporary or proposed
Treasury regulations promulgated thereunder) and (B) cause any Series 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 date" under the
REMIC Provisions.

       (c)    Within five Business Days after a Master Servicer has determined
that all amounts which it expects to recover from or on account of a Mortgage
Loan that it master services have been recovered and that no further
Liquidation Proceeds will be received in connection therewith, such Master
Servicer shall provide to the Certificate Trustee a certificate of a Servicing
Officer that such Mortgage Loan became a Liquidated Mortgage Loan as of the
date of such determination.

       Section 3.04.  Collection of Taxes, Assessments and Similar Items;
Servicing Accounts.

       (a)    Each Master Servicer will establish and maintain, in addition to
the Protected Accounts, one or more Servicing Accounts.  Each Master Servicer
will deposit and retain therein all otherwise unapplied collections from the
Mortgagors under the Mortgage Loans that it master





                                       29
<PAGE>   34
services, including amounts collected for the payment of taxes, assessments,
insurance premiums, or comparable items, as agent of such Mortgagors.

       (b)    The deposits in the Servicing Accounts shall be held in a
Designated Depository Institution in an account designated as a "Mortgage Loan
Servicing Account," held in trust by the applicable Master Servicer as Trustee
of Taxes and Insurance Custodial Account for Mortgagors and for the applicable
Master Servicer (and its successors and assigns) acting on its own behalf and
for such Master Servicer, as agent for holders of various pass-through
securities and other interests in mortgage loans sold by it, and agent for
various mortgagors, as their interests may appear, or under such other
designation as may be permitted by the Certificate Trustee.  The amount at any
time credited to a Servicing Account must be fully insured by the FDIC, or, to
the extent that such deposits exceed the limits of such insurance, such excess
must be (i) transferred to another fully insured account in another Designated
Depository Institution or (ii) if permitted by applicable law, invested in
Permitted Investments held in trust by the Master Servicer as described above
and maturing, or subject to redemption or withdrawal, no later than the date on
which such funds are required to be withdrawn, and in no event later than 45
days after the date of investment.  The Master Servicers may establish
Servicing Accounts not conforming to the foregoing requirements to the extent
that such Servicing Accounts are Rating Agency Eligible Accounts.  Withdrawals
of amounts from the Servicing Accounts may be made only to effect timely
payment of taxes, assessments, insurance premiums, or comparable items, to
transfer previously unapplied collections to a Protected Account, to reimburse
the applicable Master Servicer for any advances made with respect to such
items, to refund to any Mortgagors any sums as may be determined to be
overages, to pay interest, if required, to Mortgagors on balances in the
Servicing Accounts or to clear and terminate the Servicing Accounts at or any
time after the termination of this Agreement in accordance with Section 10.01.

       Section 3.05.  Access to Certain Documentation and Information Regarding
the Mortgage Loans.  Each Master Servicer shall provide to the Certificate
Trustee and the Depositor access to the records and documentation regarding the
related Mortgage Loans and REO Property and the servicing thereof and to the
Certificateholders, the FDIC, and the supervisory agents and examiners of the
FDIC (to which the Certificate Trustee shall also provide) access to the
documentation regarding the related Mortgage Loans required by applicable
regulations, such access being afforded without charge but only upon reasonable
prior written request and during normal business hours at the offices of such
Master Servicer, the Custodian or the Certificate Trustee that are designated
by these entities; provided, however, that, unless otherwise required by law,
the Certificate Trustee, the Custodian or a Master Servicer shall not be
required to provide access to such records and documentation if the provision
thereof would violate the legal right to privacy of any Mortgagor; provided
further, however, that the Certificate Trustee and the Depositor shall
coordinate their requests for such access so as not to impose an unreasonable
burden on, or cause an interruption of, the business of a Master Servicer.  The
Master Servicers, the Custodian and the Certificate Trustee shall allow
representatives of the above entities to photocopy any of the records and
documentation and shall provide equipment for that purpose at a charge that
covers their own actual out-of-pocket costs.





                                       30
<PAGE>   35
       Section 3.06.  Maintenance of Primary Mortgage Insurance Policies;
Collection Thereunder.  Each Master Servicer shall exercise its best reasonable
efforts to maintain and keep in full force and effect each Primary Mortgage
Insurance Policy by a Qualified Insurer, or other insurer satisfactory to the
Rating Agencies, with respect to each related conventional Mortgage Loan as to
which as of the Cut-off Date such Primary Mortgage Insurance Policy was in
effect (or, in the case of a Substitute Mortgage Loan, the date of
substitution) and the original principal amount of the related Mortgage Note
exceeded 80% of the Original Value of the related Mortgaged Property in an
amount at least equal to the excess of such original principal amount over 75%
of such Original Value until the principal amount of any such Mortgage Loan is
reduced below 80% of the Original Value or, based upon a new appraisal, the
principal amount of such Mortgage Loan represents less than 80% of the new
appraised value.  The related Master Servicer shall effect the timely payment
of the premium on each Primary Mortgage Insurance Policy.  The related Master
Servicer shall have the power to substitute for any Primary Mortgage Insurance
Policy another substantially equivalent policy issued by another Qualified
Insurer.

       Section 3.07.  Maintenance of Hazard Insurance and Fidelity Coverage.

       (a)    Each Master Servicer shall maintain and keep, with respect to
each related Mortgage Loan and each REO Property, in full force and effect
hazard insurance (fire insurance with extended coverage) equal to at least the
lesser of the Outstanding Principal Balance of the Mortgage Loan or the current
replacement cost of the Mortgaged Property, and containing a standard mortgagee
clause; provided, however, that the amount of hazard insurance may not be less
than the amount necessary to prevent loss due to the application of any
co-insurance provision of the related policy.  Unless applicable state law
requires a higher deductible, the deductible on such hazard insurance policy
may be $1000 or 1% of the applicable amount of coverage, whichever is less.  In
the case of a condominium unit or a unit in a planned unit development, the
required hazard insurance shall take the form of a multiperil policy covering
the entire condominium project or planned unit development, in an amount equal
to at least 100% of the insurable value based on replacement cost.

       (b)    Any amounts collected by a Master Servicer under any such hazard
insurance policy (other than amounts to be applied to the restoration or repair
of the related Mortgaged Property or amounts released to the related Mortgagor
in accordance with the Master Servicer's normal servicing procedures, the terms
of the related Mortgage Note, the related Security Instrument or applicable
law) shall be deposited initially in a Protected Account, for transmittal to
the Certificate Account, subject to withdrawal pursuant to Section 4.03.

       (c)    Any cost incurred by a Master Servicer in maintaining any such
hazard insurance policy shall not be added to the amount owing under the
related Mortgage Loan for the purpose of calculating monthly distributions to
Certificateholders, notwithstanding that the terms of such Mortgage Loan so
permit.  Such costs shall be recoverable by such Master Servicer as a Servicing
Advance.

       (d)    No earthquake or other additional insurance is to be required of
any Mortgagor or maintained on REO Property other than pursuant to such
applicable laws and regulations as shall at any time be in force and shall
require such additional insurance.  Each year, in accordance with





                                       31
<PAGE>   36
standards and procedures required by Freddie Mac, each Master Servicer shall
perform a review of the Mortgage Loans master serviced by it to determine
which, if any, of the related Mortgaged Properties are located in a federally
designated special flood hazard area and for each Mortgaged Property found to
be located in a federally designated special flood hazard area, the related
Master Servicer shall use its best reasonable efforts to cause with respect to
the related Mortgage Loans and each REO Property, flood insurance (to the
extent available and in accordance with mortgage servicing industry practice)
to be maintained.  Such flood insurance shall cover the related Mortgaged
Property, including all items taken into account in arriving at the Appraised
Value on which the Mortgage Loan was based, and shall be in an amount equal to
the lesser of (i) the Outstanding Principal Balance of the related Mortgage
Loan and (ii) the minimum amount required under the terms of coverage to
compensate for any damage or loss on a replacement cost basis, but not more
than the maximum amount of such insurance available for the related Mortgaged
Property under either the regular or emergency programs of the National Flood
Insurance Program (assuming that the area in which such Mortgaged Property is
located is participating in such program).  Unless applicable state law
requires a higher deductible, the deductible on such flood insurance may not
exceed $1,000 or 1% of the applicable amount of coverage, whichever is less.

       (e)    If insurance on each REO Property has not been maintained
complying with Sections 3.07(a) and (d) and there shall have been a loss which
would have been covered by such insurance had it been maintained, the related
Master Servicer shall pay for any necessary repairs of such REO Property.

       (f)    The related Master Servicer shall present, if it is a permitted
claimant, claims under the related hazard insurance or flood insurance policy.

       (g)    Each Master Servicer shall obtain and maintain an errors and
omissions insurance policy covering such Master Servicer's officers, employees
and other persons acting on its behalf in connection with its activities under
this Agreement.  The amount of coverage shall be at least equal to the coverage
acceptable to FNMA or Freddie Mac to service loans for it or otherwise in an
amount as is commercially available at a cost that is generally not regarded as
excessive by industry standards.  Each Master Servicer shall maintain at its
own expense and for the duration of this Agreement a fidelity bond in such
amount as is customary for master servicers of mortgage loans.  Each Master
Servicer shall promptly notify the Certificate Trustee of any material change
in the terms of its bond or policy.  If any such bond of a Master Servicer
ceases to be in effect, such Master Servicer shall use its best efforts to
obtain a comparable replacement bond or policy, as the case may be.  Any
amounts relating to the Mortgage Loans collected under such bond or policy
shall be remitted to the Certificate Account to the extent that such amounts
have not previously been paid to such account.

       Section 3.08.  Due-on-Sale Clauses; Assumption Agreements.

       (a)    In any case in which a Master Servicer is notified that a
Mortgaged Property relating to a Mortgage Loan that it master services has been
or is about to be conveyed by the Mortgagor, such Master Servicer shall enforce
any due-on-sale clause contained in the related Security Instrument to the
extent permitted under the terms of the related Mortgage Note and by applicable





                                       32
<PAGE>   37
law unless such Master Servicer reasonably believes such enforcement is likely
to result in legal action by the Mortgagor.  If such Master Servicer reasonably
believes that such due-on-sale clause cannot be enforced under applicable law
or if the related Mortgage Loan does not contain a due-on-sale clause, such
Master Servicer may consent to a conveyance subject to the lien of the Security
Instrument, and to take or enter into an assumption agreement from or with the
Person to whom such Mortgaged Property has been or is about to be conveyed,
pursuant to which such Person becomes liable under the related Mortgage Note
and unless prohibited by applicable state law, such Mortgagor remains liable
thereon, on condition, however, that the related Mortgage Loan shall continue
to be covered (if so covered before such Master Servicer enters into such
agreement) by any Primary Mortgage Insurance Policy.  Such Master Servicer
shall notify the Certificate Trustee, whenever possible, before the completion
of such assumption agreement, and shall forward to the Custodian on behalf of
the Certificate Trustee the original copy of such assumption agreement, which
copy shall be added by the Custodian to the related Mortgage File and which
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.  In
connection with any such assumption agreement, the interest rate on the related
Mortgage Loan shall not be changed and no other material alterations in the
Mortgage Loan shall be made.  Any fee or additional interest collected by a
Master Servicer for consenting to any such conveyance or entering into any such
assumption agreement may be retained by such Master Servicer as additional
master servicing compensation.

       (b)    Notwithstanding the foregoing paragraph or any other provision of
this Agreement, a Master Servicer shall not be deemed to be in default, breach
or any other violation of its obligations under this Agreement by reason of any
assumption by operation of law of a Mortgage Loan that it master services or
any conveyance by the Mortgagor of the related Mortgaged Property or assumption
of a Mortgage Loan which such Master Servicer reasonably believes, based on
prudent servicing standards, it 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, or, in such
Master Servicer's judgment, be reasonably likely to result in legal action by
the Mortgagor or would otherwise adversely affect the Certificateholders.

       Section 3.09.  Realization upon Defaulted Mortgage Loans. (a)  Each
Master Servicer shall foreclose upon or otherwise comparably convert the
ownership of properties securing any Mortgage Loans that it master services
that come into and continue in default and as to which no satisfactory
arrangements can be made for collection of delinquent payments pursuant to
Section 3.03; provided, however, that a Master Servicer shall not foreclose
upon or otherwise comparably convert a Mortgaged Property if there is evidence
of environmental hazards or toxic waste thereon and such Master Servicer
determines it would be imprudent to do so or not in accordance with appropriate
servicing standards.  A Master Servicer can conclusively rely on results of
third party inspections from parties it reasonably believes are qualified to
conduct such inspections.  In connection with such foreclosure or other
conversion, the related Master Servicer shall use its best reasonable efforts
to preserve REO Property and to realize upon related defaulted Mortgage Loans
in such manner as to maximize the receipt of principal and interest by the
Certificateholders, taking into account, among other things, the timing of
foreclosure and the considerations set forth in Section 3.08(b).  The foregoing
is subject to the proviso that a Master Servicer shall not be required to
expend its own funds in connection with any foreclosure or towards the
restoration of any property unless it





                                       33
<PAGE>   38
determines in good faith (i) that such restoration or foreclosure will increase
the proceeds of liquidation of the related Mortgage Loan to Certificateholders
after reimbursement to itself for such expenses and (ii) that such expenses
will be recoverable to it either through Liquidation Proceeds (respecting which
it shall have priority for purposes of reimbursements from the Certificate
Account pursuant to Section 4.03) or through Insurance Proceeds (respecting
which it shall have similar priority).  A 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 (as well
as its normal servicing compensation), and to receive Excess Liquidation
Proceeds as additional servicing compensation, to the extent that transfers or
withdrawals from the Certificate Account with respect thereto are permitted
under Section 4.03.  Any income from or other funds (net of any income taxes)
generated by REO Property shall be deemed for purposes of this Agreement to be
Insurance Proceeds.

       (b)    No Trust shall acquire any real property (or any personal
property incident to such real property) except in connection with a default or
imminent default of a Mortgage Loan.  In the event that a Trust acquires any
real property (or personal property incident to such real property) in
connection with a default or imminent default of a Mortgage Loan, such property
shall be disposed of by such Trust before the close of the third taxable year
following the taxable year in which such Trust acquired such property (the
"grace period") unless the Certificate Trustee shall have received a REMIC
Opinion with respect to such longer retention or the applicable Master Servicer
applies for and receives an extension of the grace period under Section
856(e)(3) of the Code, in which case such grace period described above will be
extended by the period set forth in such REMIC Opinion or approved application,
as the case may be.  The cost of any such REMIC Opinion shall be borne by the
related Trust.

       Section 3.10.  Certificate Trustee to Cooperate; Release of Mortgage
Files.

       (a)    Upon payment in full of any Mortgage Loan or the receipt by the
related Master Servicer of a notification that payment in full will be escrowed
in a manner customary for such purposes, the related Master Servicer will
immediately notify the Custodian by a certification signed by a Servicing
Officer in the Form of Exhibit D (which certification shall include a statement
to the effect that all amounts received or to be received in connection with
such payment which are required to be deposited in the Certificate Account have
been or will be so deposited in such account) and shall request delivery to the
applicable Master Servicer of the Mortgage File.  Upon receipt of such
certification and request, the Certificate Trustee shall cause the Custodian to
within five Business Days release the related Mortgage File to the applicable
Master Servicer and execute and deliver to the applicable Master Servicer,
without recourse, the request for reconveyance, deed of reconveyance or release
or satisfaction of mortgage or such instrument releasing the lien of the
Security Instrument (furnished by the related Master Servicer), together with
the Mortgage Note with written evidence of cancellation thereon.  No expenses
incurred in connection with any instrument of satisfaction or deed of
reconveyance shall be chargeable to the Certificate Account.  If upon receipt
of a properly executed request for release the Custodian fails to release the
Mortgage File to the applicable Master Servicer within the time limits required
under this Agreement, the Custodian shall indemnify such Master Servicer for
any penalties, charges, costs or damages payable as a result of such failure.





                                       34
<PAGE>   39
       (b)    From time to time as is appropriate for the servicing or
foreclosure of any Mortgage Loan or collection under a Required Insurance
Policy, the Master Servicer with respect to such Mortgage Loan shall deliver to
the Certificate Trustee and the Custodian a Request for Release signed by a
Servicing Officer on behalf of such Master Servicer in substantially the form
attached as Exhibit D hereto.  Upon receipt of the Request for Release, the
Certificate Trustee shall cause the Custodian to deliver the Mortgage File to
such Master Servicer.

       (c)    The applicable Master Servicer shall cause each Mortgage File
released to it pursuant to Section 3.10(b) to be returned to the Custodian when
the need therefor no longer exists, unless the related Mortgage Loan has become
a Liquidated Mortgage Loan and the Liquidation Proceeds relating to the
Mortgage Loan have been deposited in the Certificate Account or such Mortgage
File is being used to pursue foreclosure or other legal proceedings.  Prior to
return of a Mortgage File to the Custodian, the Master Servicer to whom such
file was delivered shall retain such file in its control unless the Mortgage
File has been delivered to an attorney, or to a public trustee or other public
official as required by law, to initiate or pursue legal action or other
proceedings for the foreclosure of the related Mortgaged Property either
judicially or non-judicially, and such Master Servicer has delivered to the
Custodian a certificate of a Servicing Officer certifying as to the name and
address of the Person to which such Mortgage File was delivered and the purpose
or purposes of such delivery.  If a Mortgage Loan becomes a Liquidated Mortgage
Loan, the applicable Master Servicer shall deliver the Request for Release with
respect thereto to the Custodian upon deposit of the related Liquidation
Proceeds in the Certificate Account.

       (d)    The Certificate Trustee shall execute and deliver to the related
Master Servicer any court pleadings, requests for trustee's sale or other
documents necessary or desirable to (i) the foreclosure or trustee's sale with
respect to a Mortgaged Property; (ii) any legal action brought to obtain
judgment against any Mortgagor on the related Mortgage Note or Security
Instrument; (iii) obtain a deficiency judgment against the related Mortgagor;
or (iv) enforce any other rights or remedies provided by such Mortgage Note or
Security Instrument or otherwise available at law or in equity.  Together with
such documents or pleadings, such Master Servicer shall deliver to the
Certificate Trustee a certificate of a Servicing Officer in which it requests

and delivery of the pleadings or documents will not invalidate any insurance
coverage under the Required Insurance Policies or invalidate or otherwise
affect the lien of the related Security Instrument, except for the termination
of such a lien upon completion of the foreclosure or trustee's sale.

the steps being taken by such Master Servicer to remedy such default; (iii) a
review of the reports required to be furnished by such Master Servicer pursuant
to this Agreement during such Master Servicer's most recently ended fiscal year

on his review of such reports (unless the Servicing Officer has reason to
believe that reliance on such reports is not justified), either nothing has
come to the attention of such Servicing Officer that would cause such Servicing
Officer to believe that such Master Servicer has failed to perform and fulfill
its duties, responsibilities and obligations under this Agreement in all
material respects throughout the year, or, if there has been a default in
performance or fulfillment of any such duties, responsibilities or obligations,

shall exist, each Master Servicer with respect to the Mortgage Loans included
in such Series REMIC and the Certificate Trustee shall act in accordance
herewith to assure continuing treatment of each such Series REMIC as a REMIC,
and the Certificate Trustee shall comply with any directions of the applicable
Master Servicer to assure such continuing treatment.  In particular, the

                                   ARTICLE IV
                                    ACCOUNTS

       Section 4.01.  Protected Accounts.

       (a)    Each Master Servicer shall establish and maintain one or more
Protected Accounts complying with the requirements set forth in this Section
4.01, with records to be kept with respect thereto on a Mortgage Loan by
Mortgage Loan basis, into which accounts shall be deposited within two Business
Days after receipt all collections of principal and interest with respect to
any Mortgage Loan and with respect to any REO Property received by such Master
Servicer, or a sub-servicer engaged by such Master Servicer, including
Principal Prepayments, Insurance Proceeds, Liquidation Proceeds and advances
made from the Master Servicer's own funds (less servicing compensation as
permitted by Subsection 3.11(a)) together with all other amounts to be
deposited in the Protected Accounts.  Each Master Servicer is hereby authorized
to make withdrawals from and deposits to the Protected Accounts maintained by
it for purposes required or permitted by this Agreement.  All Protected
Accounts shall be held in a Designated Depository Institution and segregated on
the books of such institution.  The amount at any time credited to a Protected
Account shall be fully insured by the FDIC or, to the extent that such balance
exceeds the lesser of $100,000 or the limits of such insurance, such excess
must be transferred to the Certificate Account or invested in Permitted
Investments or may be deposited in a Rating Agency Eligible Account in the name
of the Certificate Trustee for the benefit of Certificateholders and, except as
provided in the next sentence, not commingled with any other funds.  Each
Master Servicer may transfer funds to other accounts (which shall for purposes
hereof be deemed to be Protected Accounts), commingle accounts or establish
Protected Accounts not conforming to the foregoing requirements, to the extent
that such other accounts or Protected Accounts meet the requirements of each of
the Rating Agencies for the maintenance of the ratings on the Bonds.

       The Protected Accounts established by BAFSB may contain funds that
belong to one or more trust funds created for mortgage pass-through
certificates of other series and may contain other funds respecting payments on
mortgage loans owned or serviced by BAFSB on behalf of others; provided,





                                       39
<PAGE>   44
however, that if the long term deposit rating of BAFSB falls below "A1" by
Moody's, then either (a) BAFSB shall establish a separate Protected Account,
and shall segregate and hold funds collected and received pursuant to each BA
Mortgage Loan separate and apart from any such funds collected and received by
BAFSB with respect to any mortgage loans other than the BA Mortgage Loans,
which shall at all times be insured by the FDIC up to the FDIC insurance
limits, or must be invested in Permitted Investments for the benefit of the
Purchaser or (b) BAFSB must obtain written consent of Moody's to continue to
maintain the Protected Accounts in accordance with this Section.
Notwithstanding such commingling of funds, BAFSB shall keep records that
accurately reflect the funds on deposit in a Protected Account that have been
identified by it as being attributable to the BA Mortgage Loans.

       Amounts on deposit in a Protected Account may be invested in Permitted
Investments in the name of the applicable Master Servicer for the benefit of
Certificateholders and, except as provided in the preceding two paragraphs, not
commingled with any other funds, such Permitted Investments to mature, or to be
subject to redemption or withdrawal, no later than the date on which such funds
are required to be withdrawn for deposit in the Certificate Account, and shall
be held until required for such deposit.  The income earned from Permitted
Investments made pursuant to this Section 4.01 shall be paid to the related
Master Servicer as additional compensation for its obligations under this
Agreement, and the risk of loss of moneys required to be distributed to the
Certificateholders resulting from such investments shall be borne by and be the
risk of such Master Servicer.  Such Master Servicer shall deposit the amount of
any such loss in the related Protected Account within two Business Days of
receipt of notification of such loss but not later than the second Business Day
prior to the Remittance Date.

       (b)    On or before each Master Servicer Remittance Date, each Master
Servicer shall withdraw from the applicable Protected Accounts and shall
immediately remit to the Certificate Account amounts representing the following
collections and payments (other than with respect to principal of or interest
on the Mortgage Loans with respect to which it is Master Servicer due on or
before the Cut-off Date):

              (i)    Scheduled Payments on such Mortgage Loans received by it
       or by any sub-servicer engaged by it or any related portion thereof
       advanced by such Master Servicer or such sub-servicer which were due on
       or before the related Due Date, net of the amount thereof comprising the
       applicable Master Servicing Fee and less any amounts to be withdrawn
       later by the applicable Master Servicer from the applicable Buydown Fund
       Accounts;

              (ii)   Full Principal Prepayments and any Liquidation Proceeds
       with respect to such Mortgage Loans received by such Master Servicer or
       by its sub-servicer with respect to such Mortgage Loans in the related
       Prepayment Period, with interest to the date of prepayment or
       liquidation, net of the amount thereof comprising the applicable Master
       Servicing Fee due such Master Servicer, to the extent such amounts
       exceed the related Compensating Interest Payments;





                                       40
<PAGE>   45
              (iii)  Partial prepayments of principal with respect to such
       Mortgage Loans received by such Master Servicer or by its sub-servicer
       in the related Prepayment Period;

              (iv)   Any amount to be used as a Certificate Account Advance;
       and

              (v)    Any amount withdrawn from a Buydown Fund Account in
       respect of a Buydown Loan as provided in Section 4.04.

       (c)    Withdrawals may be made from a Protected Account only to (i) make
remittances as provided in Section 4.01(b); (ii)  reimburse the applicable
Master Servicer for advances of principal and interest which have been
recovered by subsequent collection from the related Mortgagor; (iii) remove
amounts deposited in error; (iv) remove fees, charges or other such amounts
deposited on a temporary basis; or (v) clear and terminate the account at the
termination of this Agreement in accordance with Section 10.01.  As provided in
Section 4.02(b) certain amounts otherwise due to the Master Servicer may be
retained by it and need not be deposited in the Certificate Account.

       Section 4.02.  Certificate Account.

       (a)    The Certificate Trustee shall establish and maintain in the name
of the Certificate Trustee, for the benefit of the Certificateholders, the
Certificate Account as a segregated non-interest bearing trust account or
accounts.  The Certificate Trustee shall maintain detailed transaction entries
with respect to each Series (therein called "subaccounts") reflecting the funds
held for each such Series in the Certificate Account.  The Certificate Trustee
will deposit in the Certificate Account, as identified by the applicable Master
Servicer, as received, the following amounts and shall account for such amounts
by way of subaccounts with respect to each Series:

              (i)    Any amounts withdrawn from the Protected Accounts pursuant
       to Section 4.01(b) or from a Servicing Account pursuant to Section
       3.04(b);

              (ii)   Any Monthly Advance and any Compensating Interest
       Payments;

              (iii)  Any Insurance Proceeds or Liquidation Proceeds received by
       or on behalf of the applicable Master Servicer which were not deposited
       in a Protected Account less any amounts to be withdrawn later by the
       applicable Master Servicer from the applicable Buydown Fund Accounts;

              (iv)   The Repurchase Price with respect to any Mortgage Loans or
       REO Property purchased by BSMCC pursuant to Sections 2.02 or 2.04, any
       amounts which are to be treated pursuant to Section 2.04 as the payment
       of such a Repurchase Price, and all proceeds of any Mortgage Loans or
       property acquired with respect thereto repurchased by BSMCC or its
       designee or the Depositor pursuant to Section 10.01;

              (v)    Any amounts required to be deposited with respect to
       losses on Permitted Investments; and





                                       41
<PAGE>   46
              (vi)   Any other amounts received by or on behalf of a Master
       Servicer or the Certificate Trustee and required to be deposited in the
       Certificate Account pursuant to this Agreement.

       (b)    All amounts deposited to the Certificate Account shall be held by
the Certificate Trustee in the name of the Certificate Trustee in trust for the
benefit of the Certificateholders in accordance with the terms and provisions
of this Agreement, subject to the right of each Master Servicer to require the
Certificate Trustee to make withdrawals therefrom as provided herein.  The
foregoing requirements for crediting the Certificate Account shall be
exclusive, it being understood and agreed that, without limiting the generality
of the foregoing, payments in the nature of (i) late payment charges or
assumption, tax service, statement account or payoff, substitution,
satisfaction, release and other like fees and charges and (ii) the items
enumerated in Section 4.03(a)(i) through (xi) need not be credited by the
related Master Servicer to the Certificate Account and may be retained by such
Master Servicer as servicing compensation.  In the event that a Master Servicer
shall deposit or cause to be deposited to the Certificate Account any amount
not required to be credited thereto, the Certificate Trustee, upon receipt of a
written request therefor signed by a Servicing Officer of such Master Servicer,
shall promptly transfer such amount to such Master Servicer, any provision
herein to the contrary notwithstanding.

       (c)    The Certificate Account shall constitute a trust account of the
Trusts segregated on the books of the Certificate Trustee and held by the
Certificate Trustee in trust in its Corporate Trust Office , and the
Certificate Account and the funds deposited therein shall not be subject to,
and shall be protected from, all claims, liens, and encumbrances of any
creditors or depositors of the Certificate Trustee and each Master Servicer
(whether made directly, or indirectly through a liquidator or receiver of the
Certificate Trustee or any Master Servicer).  The amount at any time credited
to the Certificate Account shall be (i) fully insured by the FDIC to the
maximum coverage provided thereby, or (ii)  invested in such Permitted
Investments as the Certificate Trustee may select.  All Permitted Investments
shall mature or be subject to redemption or withdrawal on or before, and shall
be held until, the next succeeding Distribution Date if the obligor for such
Permitted Investment is the Certificate Trustee or, if such obligor is any
other Person, the Business Day preceding such Distribution Date.  With respect
to the Certificate Account and the funds deposited therein, the Certificate
Trustee shall take such action as may be necessary to ensure that the
Certificateholders shall be entitled to the priorities afforded to such a trust
account (in addition to a claim against the estate of the Certificate Trustee)
as provided by 12 U.S.C. Section  92a(e), if applicable, or any applicable
comparable state statute applicable to state chartered banking corporations.

       Section 4.03.  Permitted Withdrawals and Transfers from the Certificate
Account.

       (a)    The Certificate Trustee will, from time to time on demand of a
Master Servicer, make or cause to be made such withdrawals or transfers from
the Certificate Account as such Master Servicer has designated for such
transfer or withdrawal as specified in a certificate signed by a Servicing
Officer (upon which the Certificate Trustee may conclusively rely) for the
following purposes (limited in the case of amounts due such Master Servicer to
those not withdrawn from the related Protected Accounts in accordance with the
terms of this Agreement):





                                       42
<PAGE>   47
              (i)    to reimburse such Master Servicer for any Monthly Advance
       or Servicing Advance of its own funds or any advance of such Master
       Servicer's own funds, the right of a Master Servicer to reimbursement
       pursuant to this subclause (i) being limited to amounts received on a
       particular Mortgage Loan with respect to which it is Master Servicer
       (including, for this purpose, the Repurchase Price therefor, Insurance
       Proceeds and Liquidation Proceeds) which represent late payments or
       recoveries of the principal of or interest on such Mortgage Loan
       respecting which such Monthly Advance or Servicing Advance was made;

              (ii)   to reimburse such Master Servicer from Insurance Proceeds
       or Liquidation Proceeds relating to a particular related Mortgage Loan
       for amounts expended by such Master Servicer in good faith in connection
       with the restoration of the related Mortgaged Property which was damaged
       by an Uninsured Cause or in connection with the liquidation of such
       Mortgage Loan;

              (iii)  to reimburse such Master Servicer from Insurance Proceeds

       Servicer from Liquidation Proceeds from a particular related Mortgage
       Loan for Liquidation Expenses incurred with respect to such Mortgage
       Loan; provided, however, that the related Master Servicer shall not be
       entitled to reimbursement for Liquidation Expenses with respect to a
       Mortgage Loan to the extent that (i) any amounts with respect to such
       Mortgage Loan were paid as Excess Liquidation Proceeds pursuant to
       clause (xi) of this Section 4.03(a) to the related Master Servicer; and
       (ii) such Liquidation Expenses were not included in the computation of
       such Excess Liquidation Proceeds;

              (iv)   to pay such Master Servicer, from Liquidation Proceeds or

       servicing compensation on account of each defaulted Scheduled Payment on
       such Mortgage Loan if paid in a timely manner by the related Mortgagor,
       but only to the extent that the aggregate of Liquidation Proceeds and
       Insurance Proceeds with respect to such Mortgage Loan, after any
       reimbursement to any Master Servicer, pursuant to subclauses (i), (ii),
       (iii) and (v) of this Section 4.03(a), exceeds the Outstanding Principal
       Balance of such Mortgage Loan plus accrued and unpaid interest thereon
       at the related Mortgage Interest Rate less the applicable Master
       Servicing Fee Rate to but not including the date of payment;

              (v)    to pay such Master Servicer from the Repurchase Price for
       any related Mortgage Loan, the amount which such Master Servicer would
       have been entitled to receive under clause (ix) of this Section 4.03(a)
       as servicing compensation, but only to the extent that the Repurchase
       Price with respect to such Mortgage Loan after any reimbursement to such
       Master Servicer pursuant to subclauses (i) and (vi) of this Section
       4.03(a) exceeds the Outstanding Principal Balance of such Mortgage Loan
       plus accrued and unpaid interest thereon at the related Mortgage
       Interest Rate less the applicable Master Servicing Fee Rate through the
       last day of the month of repurchase;

<PAGE>   48
              (vi)   to reimburse such Master Servicer for advances of funds
       hereunder, the right to reimbursement pursuant to this clause (vi) being
       limited to amounts received on the related Mortgage Loan (including, for
       this purpose, the Repurchase Price therefor, Insurance Proceeds and
       Liquidation Proceeds) which represent late recoveries of the payments
       for which such advances were made;

              (vii)  to pay such Master Servicer with respect to each related
       Mortgage Loan that has been purchased pursuant to Section 2.02, 2.04,
       2.05 or 10.01, all amounts received thereon, representing recoveries of

              (ix)   to pay such Master Servicer servicing compensation as set
       forth in Section 3.11(b);

              (x)    to reimburse such Master Servicer or the Certificate

<PAGE>   49
              (i)    First, the amount of investment earnings, net of losses,

              (ii)   Second, the amount distributable to the Holders of the
       Certificates shall be payable in accordance with Section 6.01.

       Section 4.04  Buydown Fund Accounts.  (a)  If applicable, each Master
Servicer shall establish and maintain for the benefit of the Certificateholders
a Buydown Fund Account as a segregated non-interest bearing trust account in
the corporate trust department of either a Designated Depository Institution or
the Certificate Trustee.  Each Buydown Fund Account shall constitute a trust
account of the applicable Trust segregated on the books of the Designated
Depository Institution or the Certificate Trustee, as applicable, and held by
the Designated Depository Institution or the Certificate Trustee, as applicable
in trust, and such Account and the funds deposited therein shall not be subject
to, and shall be protected from, all claims, liens, and encumbrances of any
creditors or depositors of the Designated Depository Institution, the
Certificate Trustee and each Master Servicer (whether made directly, or
indirectly through a liquidator or receiver of the Designated Depository
Institution, the Certificate Trustee or a Master Servicer).  If the Buydown
Fund Account is maintained with the Certificate Trustee, the Certificate
Trustee shall take such action as may be necessary to ensure that the
Certificateholders shall be entitled to the priorities afforded to such a trust
account (in addition to a claim against the estate of the Certificate Trustee)
as provided by 12 U.S.C. Section  92a(e), if applicable, or any applicable
comparable state statute applicable to state chartered banking corporations.

       (b)    Each Master Servicer may make withdrawals from its Buydown Fund
Account for the following purposes: (i) to deposit in its Protected Account or
the Certificate Account the amount necessary to supplement payments received on
Buydown Loans, (ii) in the event of a Principal Prepayment of any Buydown Loan,
to apply amounts remaining in the Buydown Fund Account to reduce the required
amount of such Principal Prepayment (or, if the Mortgagor has made a Principal
Prepayment, to refund such remaining Buydown Fund amounts to the person
entitled thereto); and (iii) in the event of foreclosure or liquidation of any
Buydown Loan, to deposit remaining Buydown Fund amounts in the Protected
Account or the Certificate Account as Liquidation Proceeds.

       (c)    Funds in a Buydown Fund Account may be invested at the written
direction of the applicable Master Servicer in Permitted Investments held in
trust in the name of the Certificate Trustee for the benefit of the
Certificateholders and in the absence of such directions, funds in a Buydown
Fund Account shall be invested in Permitted Investments described in clause
(iii) or clause (viii) of the definition thereof.  Such Permitted Investments
must mature, or be subject to redemption or withdrawal, no later than the date
on which such funds are required to be withdrawn for deposit in the Certificate
Account pursuant to Section 4.01(b) and shall be held in such Account until
required for such deposit.  The income earned from Permitted Investments made
pursuant to this Section 4.04 shall be paid to the applicable Master Servicer
as additional compensation for its obligations hereunder, and the risk of loss
of moneys required to be distributed to the Certificateholders resulting from
such investments shall be borne by and be the risk of the related Master
Servicer.  The amount of any such loss shall be deposited by the related Master
Servicer in





                                       45

the applicable Buydown Fund Account within two Business Days of receipt of
notification of such loss but not later than the immediately following Master
Servicer Remittance Date.

       Section 5.01. The Certificates.

       (a)    The Certificates shall be substantially in the form set forth in
Exhibit A attached hereto and shall be executed by the Depositor, authenticated
by the Certificate Trustee and delivered to or upon the order of the Depositor
upon receipt by the Certificate Trustee of the documents specified in Section

evidencing Fractional Undivided Interests.  Certificates shall be executed by
manual or facsimile signature on behalf of the Depositor and the Certificate
Trustee by authorized officers of the Depositor and the Certificate Trustee,
respectively.  Certificates bearing the manual or facsimile signatures of
individuals who were at the time of execution the proper officers of the
Depositor and the Certificate Trustee shall bind the Depositor and the
Certificate Trustee, respectively, 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
Certificates.  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 provided
for in Exhibit A hereto executed by the Depositor and the Certificate Trustee
by manual signature, and such certificate upon any Certificate shall be
conclusive evidence, and the only evidence, that such Certificate has been duly
authenticated and delivered hereunder.  All Certificates shall be dated the
date of their authentication.

       (b)    No transfer of a Certificate shall be deemed to be made in
accordance with this Section 5.01(b) unless such transfer is made pursuant to
an effective registration statement under the Securities Act or unless the
Certificate Trustee is provided with the certificates and an Opinion of
Counsel, if required, on which the Certificate Trustee may conclusively rely,
which establishes or establish to the Certificate Trustee's satisfaction that
such transfer is exempt from the registration requirements under the Securities
Act, as follows:  In the event that a transfer is to be made in reliance upon
an exemption from the Securities Act, the Certificate Trustee shall require, in
order to assure compliance with the Securities Act, that the Certificateholder
desiring to effect such transfer certify to the Certificate Trustee in writing,
by causing the execution of a Purchaser Representation Letter in substantially
the form attached hereto as Exhibit E, with such modifications to such Exhibit
E as may be appropriate to reflect the actual facts of the proposed transfer.

       Section 5.02. Certificates Issuable in Series; Authorized Denominations.
The aggregate principal amount of Certificates of a Series that may be
authenticated and delivered under this Agreement is limited to the aggregate
Scheduled Principal Balance of the Mortgage Loans in the related Mortgage Loan
Group as of the Cut-off Date. The aggregate Fractional Undivided Interest of
each Certificate of a Series that may be authenticated and delivered under this
Agreement is limited to 100%. Certificates shall be issued in Authorized
Denominations.

       Section 5.03. Registration of Transfer and Exchange of Certificates. The
Certificate Trustee shall cause to be maintained at one of its offices or at
its designated agent, a Certificate Register in which there shall be recorded
the name and address of each Certificateholder. Subject to such reasonable
rules and regulations as the Certificate Trustee may prescribe, the Certificate
Register shall be amended from time to time by the Certificate Trustee or its
agent to reflect notice of any changes received by the Certificate Trustee or
its agent pursuant to Section 11.06. The Certificate Trustee hereby appoints
itself as the initial Certificate Registrar.

       Upon surrender for registration of transfer of any Certificate of a
Series to the Certificate Trustee at the office of The First National Bank of
Chicago, 1 National Plaza, Suite 0122, Chicago, Illinois 60670, Attention:
Registered Securities, or such other address or agency as may hereafter be
provided to each Master Servicer in writing by the Certificate Trustee, the
Certificate Trustee shall execute, and the Certificate Trustee shall
authenticate and deliver, in the name of the designated transferee or
transferees, one or more new Certificates of such Series of Authorized
Denominations of like Fractional Undivided Interest.  At the option of the
Certificateholders, Certificates of a Series may be exchanged for other
Certificates of such Series in Authorized Denominations of like 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 Certificate Trustee shall execute, and authenticate and deliver,
the Certificates which the Certificateholder making the exchange is entitled to
receive.   Every Certificate presented or surrendered for transfer shall (if so
required by the Certificate Trustee) be duly endorsed by, or be accompanied by
a written instrument of transfer in form satisfactory to the Certificate
Trustee and duly executed by, the Holder thereof or such Holder's attorney duly
authorized in writing.

       A reasonable service charge may be made for any such exchange or
transfer of Certificates, and the Certificate Trustee may require payment of a
sum sufficient to cover any tax or governmental charge that may be imposed in
connection with any exchange or transfer of Certificates.

       All Certificates surrendered for exchange or transfer shall be canceled
by the Certificate Trustee.

       Section 5.04. Mutilated, Destroyed, Lost or Stolen Certificates. If (i)
any mutilated Certificate of a Series is surrendered to the Certificate
Trustee, or (ii) the Certificate Trustee receives evidence to their
satisfaction of the destruction, loss or theft of any Certificate of a Series,
and there is delivered to the Certificate Trustee such security or indemnity as
it may be required to save it harmless, then, in the absence of notice to the
Certificate Trustee that such Certificate has been acquired by a bona fide
purchaser, the Certificate Trustee shall execute, authenticate and deliver, in
exchange for or in lieu of any such mutilated, destroyed, lost or stolen
Certificate, a new Certificate of such Series of like Fractional Undivided
Interest.  Upon the issuance of any new Certificate under this Section 5.04,
the Certificate Trustee may require the payment of a sum sufficient to cover
any tax or other governmental charge that may be imposed in relation thereto
and any other expenses (including the fees and expenses of the Certificate
Trustee) connected therewith.  Any replacement Certificate of a Series issued
pursuant to this Section 5.04 shall constitute complete and indefeasible
evidence of ownership in the related Trust, as if originally issued, whether or
not the lost or stolen Certificate shall be found at any time.

Servicer, the Certificate Trustee and any agent of any of them 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 6.01
and for all other purposes whatsoever, and none of the Depositor, the Master
Servicers, the Certificate Trustee, the Certificate Registrar or any agent of
the Depositor, the Master Servicers or the Certificate Trustee shall be
affected by notice to the contrary.

       Section 5.06. Office for Transfer of Certificates.  The Certificate
Trustee shall maintain in New York, New York, an office or agency where
Certificates may be surrendered for registration of transfer or exchange.  The

address of such Holder appearing in the Certificate Register.

       (b)    All reductions in the Certificate Principal Balance of a
Certificate effected by distributions of principal with respect to Mortgage
Loans made on any Distribution Date shall be binding upon all Holders of such
Certificate and of any Certificate issued upon the registration of transfer or
exchange therefor or in lieu thereof, whether or not such distribution is noted
on such Certificate. The final distribution of principal of each Certificate
shall be payable in the manner provided above only upon presentation and
surrender thereof on or after the Distribution Date therefor at the office or

principal and the amount that represents interest, and the applicable

filing of any paper or further act on the part of any of the parties hereto,
anything herein to the contrary notwithstanding.

       Section 7.03.  Indemnification of the Certificate Trustee.  The Trusts
shall indemnify the Indemnified Persons for, and to hold them harmless against,
any loss, liability or expense incurred on their part, arising out of, or in
connection with, this Agreement, including the costs and expenses (including
reasonable legal fees and expenses) of defending themselves against any such
claim other than (i) any loss, liability or expense related to any such
Indemnified Person's failure to perform such Indemnified Person's duties in
strict compliance with this Agreement (except as any such loss,





                                       51
<PAGE>   56

Agreement) and (ii) any loss, liability or expense incurred by reason of any

individually and not jointly, shall indemnify the Indemnified Persons for, and
hold them harmless against, any loss, liability or expense incurred on its
part, arising out of, or in connection with, this Agreement, including the
costs and expenses (including reasonable legal fees and expenses) of defending
themselves against any such claim, but only to the extent any such loss,
liability or expense results solely from such Master Servicer's failure to
perform its duties in strict compliance with this Agreement.  This indemnity
shall survive the resignation or removal of the Certificate Trustee and the
termination of this Agreement.

       Section 7.04.  Limitation on Liability of the Master Servicer and
Others.

       (a)    Neither Master Servicer nor any of its directors, officers,
employees or agents shall be under any liability to the Indemnified Persons,
the Depositor, the Trusts or the Certificateholders for taking any action or
for refraining from taking any action in good faith pursuant to this Agreement,
or for errors in judgment; provided, however, that this provision shall not
protect a Master Servicer or any such Person against any breach of warranties
or representations made herein by it or any liability which would otherwise be
imposed on it by reason of such Person's willful misfeasance, bad faith or
negligence in the performance of duties or by reason of reckless disregard of
obligations and duties hereunder.

       (b)    Each Master Servicer and any of its directors, officers,
employees or agents 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.

       (c)    Each Master Servicer and any of its directors, officers,
employees or agents shall be indemnified by the Trusts and held harmless
thereby against any loss, liability or expense incurred in connection with any
legal proceedings relating to this Agreement or the Certificates (including
reasonable legal fees and disbursements of counsel), other than (i) any loss,
liability or expense related to its failure to perform its duties in strict
compliance with this Agreement (except as any such loss, liability or expense
shall be otherwise reimbursable pursuant to this Agreement) and (ii) any loss,
liability or expense incurred by reason of such Person's willful misfeasance,
bad faith or negligence in the performance of duties hereunder or by reason of
reckless disregard of obligations and duties hereunder.

       (d)    Neither Master Servicer shall be under any obligation to appear
in, prosecute or defend any legal action that is not incidental to its duties
under this Agreement and that in its opinion may involve it in any expense or
liability; provided, however, that either Master Servicer may in its
discretion, with the consent of the Certificate Trustee, 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 shall be expenses, costs and
liabilities of the related Trusts, and such Master Servicer shall be entitled
to be reimbursed therefor out of the related





                                       52

Nothing in this Section 7.04(d) shall affect a Master Servicer's obligation to
supervise the servicing and administration of the Mortgage Loans pursuant to
Section 3.01(a).

       (e)    In taking or recommending any course of action pursuant to this
Agreement, unless specifically required to do so pursuant to this Agreement, no
Master Servicer shall be required to investigate or make recommendations
concerning potential liabilities which the Trusts might incur as a result of
such course of action by reason of the condition of the Mortgaged Properties
but each Master Servicer shall give notice to the Certificate Trustee if it has
notice of such potential liabilities.

       Section 7.05.  No Master Servicer to Resign.  Except as provided in
Section 7.06, no Master Servicer shall resign from the obligations and duties
hereby imposed on it except upon a determination that any such duties hereunder
are no longer permissible under applicable law.   Any such determination
permitting the resignation of a Master Servicer shall be evidenced by an
Opinion of Independent Counsel to such effect delivered to the Certificate
Trustee.  No such resignation by a Master Servicer shall become effective until
the Certificate Trustee or a successor to such Master Servicer reasonably
satisfactory to the Certificate Trustee shall have assumed the responsibilities
and obligations of such Master Servicer in accordance with Section 8.02 hereof.
The Certificate Trustee shall notify the Rating Agencies of the resignation of
any Master Servicer.

       Section 7.06.  Sale and Assignment of Master Servicing.  Each Master
Servicer may sell and assign its rights and delegate its duties and obligations
in their entirety as a Master Servicer under this Agreement; provided, however,
that:

              (i)    the purchaser or transferee accepting such assignment and
       delegation (a) shall be a Person which shall be qualified to service
       mortgage loans for FNMA or Freddie Mac; (b) shall have a net worth of
       not less than $10,000,000 (unless otherwise approved by each Rating
       Agency pursuant to clause (ii) below); (c) shall be reasonably
       satisfactory to the Certificate Trustee (as evidenced in a writing
       signed by the Certificate Trustee); (d) shall execute and deliver to the
       Certificate Trustee an agreement, in form and substance reasonably
       satisfactory to the Certificate Trustee, which contains an assumption by
       such Person of the due and punctual performance and observance of each
       covenant and condition to be performed or observed by it as master
       servicer under this Agreement from and after the effective date of such
       agreement;

              (ii)   each Rating Agency shall be given prior written notice of
       the identity of the proposed successor to such Master Servicer and each
       Rating Agency's rating of the Certificates in effect immediately prior
       to such assignment, sale and delegation will not be downgraded,
       qualified or withdrawn as a result of such assignment, sale and
       delegation, as evidenced by a letter to such effect delivered to such
       Master Servicer and the Certificate Trustee; and

              (iii)  the Master Servicer assigning and selling the master
       servicing shall deliver to the Certificate Trustee an Officer's
       Certificate and an Opinion of Independent Counsel,





                                       53
<PAGE>   58
       each stating that all conditions precedent to such action under this
       Agreement have been completed and such action is permitted by and
       complies with the terms of this Agreement.

No such assignment or delegation shall affect any liability of the related
Master Servicer arising prior to the effective date thereof.

                                  ARTICLE VIII
                                    DEFAULT

       Section 8.01.  Events of Default.  The term "Event of Default", wherever
used herein, means any one of the following events (whatever the reason for
such Event of Default and whether it shall be voluntary or involuntary or be
effected by operation of law or pursuant to any judgment, decree or order of
any court or any order, rule or regulation of any administrative or
governmental body):

              (i)    A Master Servicer fails to cause to be deposited in the
       Certificate Account any amount so required to be deposited pursuant to
       this Agreement, and such failure continues unremedied for a period of
       two Business Days after the date such deposit was required to be made;
       or

              (ii)   A Master Servicer fails to observe or perform in any
       material respect any other covenants and agreements set forth in this
       Agreement to be performed by it, which covenants and agreements
       materially affect the rights of Certificateholders, and such failure
       continues unremedied for a period of 60 days after the date on which
       written notice of such failure, properly requiring the same to be
       remedied, shall have been given to such Master Servicer by the
       Certificate Trustee or to such Master Servicer and the Certificate
       Trustee by the Holders of Certificates evidencing Fractional Undivided
       Interests aggregating not less than 25% of the Trust Fund for a Series;
       or

              (iii)  There is entered against a Master Servicer a decree or
       order by a court or agency or supervisory authority having jurisdiction
       in the premises for the appointment of a conservator, receiver or
       liquidator in any insolvency, readjustment of debt, marshaling of assets
       and liabilities or similar proceedings, or for the winding up or
       liquidation of its affairs, and the continuance of any such decree or
       order is unstayed and in effect for a period of 60 consecutive days, or
       an involuntary case is commenced against a Master Servicer under any
       applicable insolvency or reorganization statute and the petition is not
       dismissed within 60 days after the commencement of the case; or

              (iv)   A Master Servicer consents to the appointment of a
       conservator or receiver or liquidator in any insolvency, readjustment of
       debt, marshaling of assets and liabilities or similar proceedings of or
       relating to such Master Servicer or substantially all of its property;
       or a Master Servicer admits in writing its inability to pay its debts
       generally as they become due, files a petition to take advantage of any
       applicable insolvency or reorganization statute, makes an assignment for
       the benefit of its creditors, or voluntarily suspends payment of its
       obligations; or





                                       54
<PAGE>   59
              (v)    A Master Servicer assigns or delegates its duties or
       rights under this Agreement in contravention of the provisions
       permitting such assignment or delegation under Sections 7.05 or 7.06.

In each and every such case, so long as such Event of Default with respect to
such Master Servicer shall not have been remedied, either the Certificate
Trustee or the Holders of Certificates evidencing Fractional Undivided
Interests aggregating not less than 51% of the principal of the Trust Fund for
an affected Series, by notice in writing to such Master Servicer (and to the
Certificate Trustee if given by such Certificateholders), with a copy to the
Rating Agencies, may terminate all of the rights and obligations (but not the
liabilities) of such Master Servicer under this Agreement and in and to the
Mortgage Loans and/or the REO Property serviced by such Master Servicer and the
proceeds thereof.  Upon the receipt by a Master Servicer of such written
notice, all authority and power of such Master Servicer under this Agreement,
whether with respect to the Certificates, the applicable Mortgage Loans, REO
Property or under any other related agreements, shall, subject to Section 8.02,
automatically and without further action pass to and be vested in the
Certificate Trustee pursuant to this Section 8.01; and, without limitation, the
Certificate Trustee is hereby authorized and empowered to execute and deliver,
on behalf of the defaulting 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 applicable Mortgage Loans and related documents, or otherwise.  Each
Master Servicer agrees to cooperate with the Certificate Trustee in effecting
the termination of the defaulting Master Servicer's rights and obligations
hereunder, including, without limitation, the transfer to the Certificate
Trustee of (i) the property and amounts which are then or should be part of the
Trust or which thereafter become part of the Trust; (ii) originals or copies of
all documents of such Master Servicer reasonably requested by the Certificate
Trustee to enable it to assume such Master Servicer's duties thereunder; and
(iii) the rights and obligations of such Master Servicer under this Agreement
with respect to the applicable Mortgage Loans.  In addition to any other
amounts which are then, or, notwithstanding the termination of its activities
under this Agreement, may become payable to a terminated Master Servicer under
this Agreement, such Master Servicer shall be entitled to receive, out of any
amount received on account of any applicable Mortgage Loan or REO Property,
that portion of such payments which it would have received as reimbursement
pursuant to Section 3.11 if notice of termination had not been given.  The
termination of the rights and obligations of a Master Servicer shall not affect
any obligations incurred by such Master Servicer prior to such termination nor
the right of such Master Servicer to its accrued fees and expenses.

       Section 8.02.  Certificate Trustee to Act; Appointment of Successor.
(a)  Upon the receipt by a Master Servicer of a notice of termination pursuant
to Section 8.01 or an Opinion of Independent Counsel pursuant to Section 7.05
to the effect that such Master Servicer is legally unable to act or to delegate
its duties to a Person which is legally able to act, the Certificate Trustee
shall automatically become the successor in all respects to such Master
Servicer in its capacity under this Agreement and the transactions set forth or
provided for herein and shall thereafter be subject to all the
responsibilities, duties, liabilities and limitations on liabilities relating
thereto placed on such Master Servicer by the terms and provisions hereof;
provided, however, that the Certificate Trustee (i) shall be under no
obligation to purchase any related Mortgage Loan pursuant to Section





                                       55
<PAGE>   60
10.01; and (ii) shall have no obligation whatsoever with respect to any
liability (other than advances deemed recoverable and not previously made)
incurred by such Master Servicer at or prior to the time of receipt by such
Master Servicer of such notice or by the Certificate Trustee of such Opinion of
Independent Counsel.  As compensation therefor, the Certificate Trustee shall
be entitled to all funds relating to the Mortgage Loans which such Master
Servicer would have been entitled to retain if such Master Servicer had
continued to act hereunder, except for those amounts due such Master Servicer
as reimbursement for advances previously made or expenses previously incurred.
Notwithstanding the above, the Certificate Trustee may, if it shall be
unwilling so to act, or shall, if it is legally unable so to act, appoint or
petition a court of competent jurisdiction to appoint, any established housing
and home finance institution which is a FNMA- or Freddie Mac-approved servicer,
and with respect to a successor to a Master Servicer only, having a net worth
of not less than $10,000,000, as the successor to such Master Servicer
hereunder in the assumption of all or any part of the responsibilities, duties
or liabilities of such Master Servicer hereunder.  Pending appointment of a
successor to a Master Servicer hereunder, the Certificate Trustee shall act in
such capacity as hereinabove provided.  In connection with such appointment and
assumption, the Certificate Trustee may make such arrangements for the
compensation of such successor out of payments on the Mortgage Loans as it and
such successor shall agree; provided, however, that no such compensation shall
be in excess of that permitted the Certificate Trustee under this Subsection
8.02(a), and that such successor shall undertake and assume the obligations of
the Certificate Trustee to pay compensation to any third Person acting as an
agent or independent contractor in the performance of master servicing
responsibilities hereunder.  The Certificate Trustee and such successor shall
take such action, consistent with this Agreement, as shall be necessary to
effectuate any such succession.

       (b)    If the Certificate Trustee shall succeed to any duties of a
Master Servicer respecting the Mortgage Loans master serviced by such Master
Servicer as provided herein, it shall do so in a separate capacity and not in
its capacity as Certificate Trustee and, accordingly, the provisions of Article
IX shall be inapplicable to the Certificate Trustee in its duties as the
successor to such Master Servicer in the servicing of such Mortgage Loans
(although such provisions shall continue to apply to the Certificate Trustee in
its capacity as Certificate Trustee); the provisions of Article VII, however,
shall apply to it in its capacity as successor master servicer.

       Section 8.03.  Notification to Certificateholders.  Upon any termination
or appointment of a successor to a Master Servicer, the Certificate Trustee
shall give prompt written notice thereof to Certificateholders at their
respective addresses appearing in the Certificate Register and to the Rating
Agencies.

       Section 8.04.  Waiver of Defaults.  The Certificate Trustee shall
transmit by mail to all Certificateholders, within 60 days after the occurrence
of any Event of Default known to the Certificate Trustee, unless such Event of
Default shall have been cured, notice of each such Event of Default hereunder
known to the Certificate Trustee.  The Holders of Certificates evidencing
Fractional Undivided Interests aggregating not less than 51% of the Trust Fund
for an affected Series may, on behalf of all Certificateholders, waive any
default by a Master Servicer in the performance of its obligations hereunder
and the consequences thereof, except a default in the making of or the causing
to be made any required distribution on the Certificates of such Series.  Upon
any such





                                       56
<PAGE>   61
waiver of a past default, such default shall be deemed to cease to exist, and
any Event of Default arising therefrom shall be deemed to have been timely
remedied for every purpose of this Agreement.  No such waiver shall extend to
any subsequent or other default or impair any right consequent thereon except
to the extent expressly so waived.  The Certificate Trustee shall give notice
of any such waiver to the Rating Agencies.

       Section 8.05.  List of Certificateholders.  Upon written request of two
or more Certificateholders of record, for purposes of communicating with other
Certificateholders with respect to their rights under this Agreement, the
Certificate Trustee will afford such Certificateholders access during business
hours to the most recent list of Certificateholders held by the Certificate
Trustee.


                                   ARTICLE IX
                       CONCERNING THE CERTIFICATE TRUSTEE

       Section 9.01.  Duties of Certificate Trustee.

       (a)    The Certificate 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 duties as are
specifically set forth in this Agreement as duties of the Certificate Trustee.
If an Event of Default has occurred and has not been cured or waived, the
Certificate Trustee shall exercise such of the rights and powers vested in it
by this Agreement, and subject to Section 8.02(b) use the same degree of care
and skill in their exercise, as a prudent person would exercise under the
circumstances in the conduct of his own affairs.

       (b)    Upon receipt of all resolutions, certificates, statements,
opinions, reports, documents, orders or other instruments which are
specifically required to be furnished to the Certificate Trustee pursuant to
any provision of this Agreement, the Certificate Trustee shall examine them to
determine whether they are in the form required by this Agreement; provided,
however, that the Certificate Trustee shall not be responsible for the accuracy
or content of any resolution, certificate, statement, opinion, report,
document, order or other instrument furnished by a Master Servicer hereunder;
and provided, further, that the Certificate Trustee shall not be responsible
for the accuracy or verification of any calculation provided to it pursuant to
this Agreement.

       (c)    The Certificate Trustee shall make monthly distributions and the
final distribution to the Certificateholders as provided in Sections 6.01 and
10.01 herein.

       (d)    No provision of this Agreement shall be construed to relieve the
Certificate 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 Certificate Trustee shall be
       determined solely by the express provisions of this Agreement,





                                       57
<PAGE>   62
       the Certificate 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 Certificate Trustee and, in the absence of bad
       faith on the part of the Certificate Trustee, the Certificate 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 Certificate Trustee and conforming to the
       requirements of this Agreement.

              (ii)   The Certificate Trustee shall not be liable in its
       individual capacity for an error of judgment made in good faith by a
       Responsible Officer or Responsible Officers of the Certificate Trustee,
       unless it shall be proved that the Certificate Trustee was negligent in
       ascertaining the pertinent facts.

              (iii)  The Certificate Trustee shall not be liable with respect
       to any action taken, suffered or omitted to be taken by it in good faith
       in accordance with the directions of the Holders of Certificates
       evidencing Fractional Undivided Interests aggregating not less than 25%
       of the Trust Fund for a Series, if such action or non-action relates to
       the time, method and place of conducting any proceeding for any remedy
       available to the Certificate Trustee, or exercising any trust or other
       power conferred upon the Certificate Trustee, under this Agreement.

              (iv)   The Certificate Trustee shall not be required to take
       notice or be deemed to have notice or knowledge of any default or Event
       of Default unless a Responsible Officer of the Certificate Trustee's
       Corporate Trust Office shall have actual knowledge thereof.  In the
       absence of such notice, the Certificate Trustee may conclusively assume
       there is no such default or Event of Default.

              (v)    The Certificate Trustee shall not in any way be liable by
       reason of any insufficiency in any Account held by or in the name of
       Certificate Trustee unless it is determined by a court of competent
       jurisdiction that the Certificate Trustee's gross negligence or willful
       misconduct was the primary cause of such insufficiency.  Notwithstanding
       the preceding sentence, the Certificate Trustee shall not in any way be
       liable by reason of any insufficiency in any Account (except the
       Certificate Account) held by, or in the name of the Certificate Trustee
       resulting from any loss on any Permitted Investment invested pursuant to
       Article IV of this Agreement.

              (vi)   Anything in this Agreement to the contrary
       notwithstanding, in no event shall the Certificate Trustee be liable for
       special, indirect or consequential loss or damage of any kind whatsoever
       (including but not limited to lost profits), even if the Certificate
       Trustee has been advised of the likelihood of such loss or damage and
       regardless of the form of action.

       The Certificate Trustee shall not be required to expend or risk its own
funds or otherwise incur financial liability in the performance of any of its
duties hereunder, or in the exercise of any of its rights or powers, if there
is reasonable ground for believing that the repayment of such funds or adequate
indemnity against such risk or liability is not reasonably assured to it, and
none of the





                                       58
<PAGE>   63
provisions contained in this Agreement shall in any event require the
Certificate Trustee to perform, or be responsible for the manner of performance
of, any of the obligations of a Master Servicer under this Agreement, except
during such time, if any, as the Certificate Trustee shall be the successor to,
and be vested with the rights, duties, powers and privileges of, such Master
Servicer in accordance with the terms of this Agreement.

       (e)    All funds received by the Certificate Trustee and required to be
deposited in the Certificate Account pursuant to this Agreement will be
promptly so deposited by the Certificate Trustee.

       (f)    Except for those actions that the Certificate Trustee is required
to take hereunder, the Certificate Trustee shall have no obligation or
liability to take any action or to refrain from taking any action hereunder in
the absence of written direction as provided hereunder.

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

              (i)    The Certificate Trustee may rely and shall be protected in
       acting or refraining from acting in reliance on any resolution,
       Officer's Certificate, certificate of a Servicing Officer, certificate
       of auditors or any other certificate, statement, instrument, opinion,
       report, notice, request, consent, order, appraisal, bond or other paper
       or document believed by it to be genuine and to have been signed or
       presented by the proper party or parties.

              (ii)   The Certificate Trustee may consult with counsel and any
       advice of such counsel or any Opinion of Counsel shall be full and
       complete authorization and protection with respect to any action taken
       or suffered or omitted by it hereunder in good faith and in accordance
       with such advice or Opinion of Counsel.

              (iii)  The Certificate Trustee shall be under no obligation to
       exercise any of the trusts or powers vested in it by this Agreement,
       other than its obligation to give notices pursuant to this Agreement, or
       to institute, conduct or defend any litigation hereunder or in relation
       hereto at the request, order or direction of any of the
       Certificateholders pursuant to the provisions of this Agreement, unless
       such Certificateholders shall have offered to the Certificate 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 Certificate Trustee of the
       obligation, upon the occurrence of an Event of Default of which a
       Responsible Officer of the Certificate Trustee's Corporate Trust Office
       has actual knowledge (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 person
       would exercise under the circumstances in the conduct of his own
       affairs.

              (iv)   The Certificate Trustee shall not be liable in its
       individual capacity 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.





                                       59
<PAGE>   64
              (v)    The Certificate Trustee shall not be bound to make any
       investigation into the facts or matters stated in any resolution,
       certificate, statement, instrument, opinion, report, notice, request,
       consent, order, approval, bond or other paper or document, unless
       requested in writing to do so by Holders of Certificates evidencing
       Fractional Undivided Interests aggregating not less than 25% of the
       Trust Fund for a Series and provided that the payment within a
       reasonable time to the Certificate 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 Certificate Trustee, reasonably
       assured to the Certificate Trustee by the security afforded to it by the
       terms of this Agreement.  The Certificate Trustee may require reasonable
       indemnity against such expense or liability as a condition to taking any
       such action.  The reasonable expense of every such examination shall be
       paid by the Certificateholders requesting the investigation.

              (vi)   The Certificate Trustee may execute any of the trusts or
       powers hereunder or perform any duties hereunder either directly or
       through agents or attorneys; provided, however, that the Certificate
       Trustee may not appoint any agent to perform its custodial functions
       with respect to the Mortgage Files, other than the Custodian, or paying
       agent functions under this Agreement without the express written consent
       of each Master Servicer.  The Certificate Trustee shall not be liable or
       responsible for the misconduct or negligence of any of the Certificate
       Trustee's agents or attorneys or a custodian or paying agent appointed
       hereunder by the Certificate Trustee with due care and, when required,
       with the consent of each Master Servicer.

              (vii)  Should the Certificate Trustee deem the nature of any
       action required on its part, other than a payment or transfer under
       Section 4.02(b) or Section 4.03, to be unclear, the Certificate Trustee
       may require prior to such action that it be provided by a Master
       Servicer with reasonable further instructions.

              (viii) The right of the Certificate Trustee to perform any
       discretionary act enumerated in this Agreement shall not be construed as
       a duty, and the Certificate Trustee shall not be accountable for other
       than its negligence or willful misconduct in the performance of any such
       act.

              (ix)   The Certificate Trustee shall not be required to give any
       bond or surety with respect to the execution of the trust created hereby
       or the powers granted hereunder.

              (x)    The Certificate Trustee shall have no duty to conduct any
       affirmative investigation as to the occurrence of any condition
       requiring the repurchase of any Mortgage Loan by BSMCC pursuant to this
       Agreement and/or the Mortgage Loan Purchase Agreement or the eligibility
       of any Mortgage Loan for purposes of this Agreement.

       Section 9.03.  Certificate Trustee Not Liable for Certificates or
Mortgage Loans.  The recitals contained herein and in the Certificates shall be
taken as the statements of the Depositor, and the Certificate Trustee shall
have no responsibility for their correctness.  The Certificate Trustee makes no
representation as to the validity or sufficiency of the Certificates (other
than the signature and





                                       60
<PAGE>   65
countersignature of the Certificate Trustee on the Certificates) or of any
Mortgage Loan except as expressly provided in Sections 2.02 and 2.05 hereof;
provided, however, that the foregoing shall not relieve the Certificate Trustee
of its obligation to cause the Custodian to review the Mortgage Files pursuant
to Sections 2.02 and 2.05.  The Certificate Trustee's signature and
countersignature (or countersignature of its agent) on the Certificates shall
be solely in its capacity as Certificate Trustee and shall not constitute an
obligation of the Certificate Trustee in any other capacity.  The Certificate
Trustee shall not be accountable for the use or application by the Depositor of
any of the Certificates or of the proceeds of such Certificates, or for the use
or application of any funds paid to the Depositor with respect to the Mortgage
Loans.  Subject to the provisions of Section 2.05, the Certificate Trustee
shall not be responsible for the legality or validity of this Agreement or any
document or instrument relating to this Agreement, the validity of the
execution of this Agreement or of any supplement hereto or instrument of
further assurance, or the validity, priority, perfection or sufficiency of the
security for the Certificates issued hereunder or intended to be issued
hereunder.  The Certificate Trustee shall at no time have any responsibility or
liability for or with respect to the legality, validity and enforceability of
any Mortgage Loan, or the perfection and priority of any Security Agreement or
the maintenance of any such perfection and priority, or for or with respect to
the sufficiency of the related Trust Fund or its ability to generate the
payments to be distributed to Certificateholders, under this Agreement.  The
Certificate Trustee shall have no responsibility for filing any financing or
continuation statement in any public office at any time or to otherwise perfect
or maintain the perfection of any security interest or lien granted to it
hereunder or to record this Agreement.

       Section 9.04.  Certificate Trustee May Own Certificates.  The
Certificate Trustee in its individual capacity or in any capacity other than as
Certificate Trustee hereunder may become the owner or pledgee of any
Certificates with the same rights it would have if it were not Certificate
Trustee, and may otherwise deal with the parties hereto.

       Section 9.05.  Certificate Trustee's Fees and Expenses.  The Certificate
Trustee shall not be entitled to any fee except that it shall be entitled to
retain as compensation all investment income, net of any investment losses,
with respect to Permitted Investments in the Certificate Account.  Such
compensation obligation shall not be limited by any provision of law in regard
to the compensation of a Certificate Trustee of an express trust.

       Section 9.06.  Eligibility Requirements for Certificate Trustee.  The
Certificate Trustee and any successor Certificate Trustee shall during the
entire duration of this Agreement be a state bank or trust company or a
national banking association organized and doing business under the laws of
such state or the United States of America, authorized under such laws to
exercise corporate trust powers, having a combined capital and surplus and
undivided profits of at least $40,000,000 or, in the case of a successor
Certificate Trustee, $50,000,000, subject to supervision or examination by
federal or state authority and, in the case of a successor Certificate Trustee
other than pursuant to Section 9.10, rated in one of the two highest long-term
debt categories of, or otherwise acceptable to, each of the Rating Agencies.
The Certificate Trustee shall not be an Affiliate of any Master Servicer,
unless the Certificate Trustee acts as successor Master Servicer hereunder.  If
the Certificate Trustee 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





                                       61
<PAGE>   66
Section 9.06 the combined capital and surplus of such entity shall be deemed to
be its total equity capital (combined capital and surplus) as set forth in its
most recent report of condition so published.  In case at any time the
Certificate Trustee shall cease to be eligible in accordance with the
provisions of this Section 9.06, the Certificate Trustee shall resign
immediately in the manner and with the effect specified in Section 9.08.

       Section 9.07.  Insurance.  The Certificate Trustee, at its own expense,
shall at all times maintain and keep in full force and effect:  (i) fidelity
insurance, (ii) theft of documents insurance and (iii) forgery insurance (which
may be collectively satisfied by a "Financial Institution Bond" and/or a
"Bankers' Blanket Bond").  All such insurance shall be in amounts, with
standard coverage and subject to deductibles, as are customary for insurance
typically maintained by banks which act as custodians for investor-owned
mortgage pools.  A certificate of an officer of the Certificate Trustee as to
the Certificate Trustee's compliance with this Section 9.07 shall be furnished
to any Master Servicer or Certificateholder upon reasonable written request.

       Section 9.08.  Resignation and Removal of the Certificate Trustee.

       (a)    The Certificate Trustee may at any time resign and be discharged
from the Trusts hereby created by giving written notice thereof to each Master
Servicer, with a copy to the Rating Agencies.  Upon receiving such notice of
resignation, the Master Servicers shall promptly appoint a successor
Certificate Trustee by written instrument, in triplicate, one copy of which
instrument shall be delivered to each of the resigning Certificate Trustee and
the successor Certificate Trustee.  If no successor Certificate Trustee shall
have been so appointed and have accepted appointment within 30 days after the
giving of such notice of resignation, the resigning Certificate Trustee may
petition any court of competent jurisdiction for the appointment of a successor
Certificate Trustee.

       (b)    If at any time the Certificate Trustee shall cease to be eligible
in accordance with the provisions of Section 9.06 and shall fail to resign
after written request therefor by the Master Servicers or if at any time the
Certificate Trustee shall become incapable of acting, or shall be adjudged a
bankrupt or insolvent, or a receiver of the Certificate Trustee or of its
property shall be appointed, or any public officer shall take charge or control
of the Certificate Trustee or of its property or affairs for the purpose of
rehabilitation, conservation or liquidation, then the Master Servicers shall be
entitled to remove the Certificate Trustee and appoint a successor Certificate
Trustee by written instrument, in triplicate, one copy of which instrument
shall be delivered to each of the Certificate Trustee so removed and the
successor Certificate Trustee.

       (c)    The Holders of Certificates evidencing Fractional Undivided
Interests aggregating not less than 51% of the Trust Fund for each Series may
at any time remove the Certificate Trustee and appoint a successor Certificate
Trustee by written instrument or instruments, in quadruplicate, signed by such
Holders or their attorneys-in-fact duly authorized, one complete set of which
instruments shall be delivered to each Master Servicer, the Certificate Trustee
so removed and the successor so appointed.

       (d)    No resignation or removal of the Certificate Trustee and
appointment of a successor Certificate Trustee pursuant to any of the
provisions of this Section 9.08 shall become effective





                                       62
<PAGE>   67
except upon appointment of and acceptance of such appointment by the successor
Certificate Trustee as provided in Section 9.09.  All costs and expenses
incurred in connection with the resignation or removal of the Certificate
Trustee shall be paid by such Certificate Trustee.

       Section 9.09.  Successor Certificate Trustee.

       (a)    Any successor Certificate Trustee appointed as provided in
Section 9.08 shall execute, acknowledge and deliver to each Master Servicer and
to its predecessor Certificate Trustee an instrument accepting such appointment
hereunder.  The resignation or removal of the predecessor Certificate Trustee
shall then become effective and such successor Certificate Trustee, without any
further act, deed or conveyance, shall become fully vested with all the rights,
powers, duties and obligations of its predecessor hereunder, with like effect
as if originally named as Certificate Trustee herein.  The predecessor
Certificate Trustee shall after payment of its outstanding fees and expenses
promptly deliver to the successor Certificate Trustee all assets and records of
the Trust held by it hereunder, and each Master Servicer and the predecessor
Certificate 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 Certificate Trustee all such rights, powers,
duties and obligations.

       (b)    No successor Certificate Trustee shall accept appointment as
provided in this Section 9.09 unless at the time of such acceptance such
successor Certificate Trustee shall be eligible under the provisions of Section
9.06.

       (c)    Upon acceptance of appointment by a successor Certificate Trustee
as provided in this Section 9.09, the successor Certificate Trustee shall mail
notice of the succession of such Certificate Trustee hereunder to all
Certificateholders at their addresses as shown in the Certificate Register and
to the Rating Agencies.

       Section 9.10.  Merger or Consolidation of Certificate Trustee.  Any
state bank or trust company or national banking association into which the
Certificate Trustee may be merged or converted or with which it may be
consolidated or any state bank or trust company or national banking association
resulting from any merger, conversion or consolidation to which the Certificate
Trustee shall be a party, or any state bank or trust company or national
banking association succeeding to all or substantially all of the corporate
trust business of the Certificate Trustee, shall be the successor of the
Certificate Trustee hereunder, provided such state bank or trust company or
national banking association shall be eligible under the provisions of Section
9.06.  Such succession shall be valid without the execution or filing of any
paper or any further act on the part of any of the parties hereto, anything
herein to the contrary notwithstanding.

       Section 9.11.  Appointment of Co-Certificate Trustee or Separate
Certificate Trustee.

       (a)    Notwithstanding any other provisions hereof, at any time, for the
purpose of meeting any legal requirements of any jurisdiction in which any part
of the Trusts or property constituting the same may at the time be located, the
Master Servicers and the Certificate Trustee acting jointly shall have the
power and shall execute and deliver all instruments to appoint one or more
Persons





                                       63
<PAGE>   68
approved by the Certificate Trustee and the Master Servicers to act as
co-Certificate Trustee or co-Certificate Trustees, jointly with the Certificate
Trustee, or separate Certificate Trustee or separate Certificate Trustees, of
all or any part of the Trust, and to vest in such Person or Persons, in such
capacity, such title to the Trusts, or any part thereof, and, subject to the
other provisions of this Section 9.11, such powers, duties, obligations, rights
and trusts as the Master Servicers and the Certificate Trustee may consider
necessary or desirable.

       (b)    If the Master Servicers shall not have joined in such appointment
within 15 days after the receipt by it of a written request so to do, or in
case an Event of Default with respect to a Master Servicer shall have occurred
and be continuing, the Certificate Trustee shall have the power to make such
appointment without such Master Servicer or Master Servicers.

       (c)    No co-Certificate Trustee or separate Certificate Trustee
hereunder shall be required to meet the terms of eligibility as a successor
Certificate Trustee under Section 9.06 hereunder and no notice to
Certificateholders of the appointment of co-Certificate Trustee(s) or separate
Certificate Trustee(s) shall be required under Section 9.08 hereof.

       (d)    In the case of any appointment of a co-Certificate Trustee or
separate Certificate Trustee pursuant to this Section 9.11, all rights, powers,
duties and obligations conferred or imposed upon the Certificate Trustee and
required to be conferred on such co-Certificate Trustee shall be conferred or
imposed upon and exercised or performed by the Certificate Trustee and such
separate Certificate Trustee or co-Certificate Trustee jointly, except to the
extent that under any law of any jurisdiction in which any particular act or
acts are to be performed (whether as Certificate Trustee hereunder or as
successor to a Master Servicer hereunder), the Certificate Trustee shall be
incompetent or unqualified to perform such act or acts, in which event such
rights, powers, duties and obligations (including the holding of title to the
Trusts or any portion thereof in any such jurisdiction) shall be exercised and
performed by such separate Certificate Trustee or co-Certificate Trustee at the
direction of the Certificate Trustee.

       (e)    Any notice, request or other writing given to the Certificate
Trustee shall be deemed to have been given to each of the then separate
Certificate Trustees and co-Certificate Trustees, as effectively as if given to
each of them.  Every instrument appointing any separate Certificate Trustee or
co-Certificate Trustee shall refer to this Agreement and the conditions of this
Article IX.  Each separate Certificate Trustee and co-Certificate 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
Certificate 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 Certificate Trustee.  Every such instrument shall
be filed with the Certificate Trustee.

       (f)    To the extent not prohibited by law, any separate Certificate
Trustee or co-Certificate Trustee may, at any time, request the Certificate
Trustee, its agent or attorney-in-fact, with full power and authority, to do
any lawful act under or with respect to this Agreement on its behalf and in its
name.  If any separate Certificate Trustee or co-Certificate Trustee shall die,
become incapable of acting, resign or be removed, all of its estates,
properties, rights, remedies and trusts shall vest in and





                                       64
<PAGE>   69
be exercised by the Certificate Trustee, to the extent permitted by law,
without the appointment of a new or successor Certificate Trustee.

       (g)    No Certificate Trustee under this Agreement shall be personally
liable by reason of any act or omission of another Certificate Trustee under
this Agreement.  The Master Servicers and the Certificate Trustee acting
jointly may at any time accept the resignation of or remove any separate
Certificate Trustee or co-Certificate Trustee, except that following the
occurrence of any Event of Default which has not been cured, the Certificate
Trustee acting alone may accept the resignation of or remove any separate
Certificate Trustee or co-Certificate Trustee.

       Section 9.12.  Master Servicers Shall Provide Information as Reasonably
Required.  Each Master Servicer shall furnish to the Certificate Trustee,
during the term of this Agreement, such periodic, special, or other reports or
information (and in such electronic format or other means acceptable to the
Certificate Trustee) as such Master Servicer may have in its possession and as
may reasonably be requested by the Certificate Trustee in order to fulfill its
duties and obligations under this Agreement.

                                   ARTICLE X
                                  TERMINATION

       Section 10.01.  Termination of a Series Upon Repurchase by BSMCC or its
Designee or the Depositor or Liquidation of the Mortgage Loans.

       (a)    Subject to Section 10.02, the respective obligations and
responsibilities of the Depositor, the Master Servicers, the Custodian and the
Certificate Trustee created hereby, other than the obligation of the
Certificate Trustee or the Master Servicers to make payments to
Certificateholders of a Series as hereinafter set forth and to the Certificate
Trustee, shall terminate with respect to a Series upon:

              (i)    the repurchase by or at the direction of BSMCC or its
       designee (or if BSMCC or its designee does not exercise such option, the
       Depositor) of all Mortgage Loans in the Mortgage Loan Group of such
       Series and all REO Property remaining in the Trust Fund relating to such
       Mortgage Loan Group at a price equal to the aggregate Class Current
       Principal Balances of the Outstanding Bonds of the related Bond Group,
       plus accrued and unpaid interest thereof through the end of the month
       preceding the month in which such purchase occurs; or

              (ii)   the later of the making of the final payment or other
       liquidation, or any advance with respect thereto, of the last Mortgage
       Loan remaining in the Trust Fund of such Series or the disposition of
       all property acquired with respect to any Mortgage Loan of such Series;
       provided, however, that in the event that an advance has been made, but
       not yet recovered, at the time of such termination, the Person having
       made such advance shall be entitled to receive, notwithstanding such
       termination, any payments received subsequent thereto with respect to
       which such advance was made.





                                       65
<PAGE>   70
       (b)    In no event, however, shall any 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's, living on the date of this Agreement.

       (c)    The right of BSMCC or its designee or the Depositor, as the case
may be, to repurchase all Mortgage Loans in a Mortgage Loan Group pursuant to
Section 10.01(a)(i) above shall be exercisable only if (i) in the case of BSMCC
or its designee or the Depositor, the aggregate unpaid principal balance of the
Mortgage Loans in such Mortgage Loan Group at the time of any such repurchase
is less than 5% of the portion of the Cut-off Date Balance allocable to such
Mortgage Loan Group or (ii) in the case of the Depositor, the Depositor, based
upon an Opinion of Counsel, has determined that the REMIC status of any Series
REMIC has been lost or that a substantial risk exists that such REMIC status
will be lost for the then-current taxable year.  At any time thereafter, in the
case of (i) above, BSMCC or its designee, or the Depositor, and in the case of
(ii) above, the Depositor may elect to terminate the related Trust at any time,
and upon such election, BSMCC or its designee or the Depositor, as the case may
be, shall repurchase all the Mortgage Loans and REO Property of the related
Mortgage Loan Group.

       (d)    The Certificate Trustee shall give notice of any termination to
the Certificateholders of an affected Series, with a copy to the Rating
Agencies, upon which the Certificateholders shall surrender their Certificates
to the Certificate Trustee for payment of the final distribution and
cancellation.  Such notice shall be given by letter, mailed not earlier than
the 15th day and not later than the 25th day of the month next preceding the
month of such final distribution, and shall specify (i) the Distribution Date
upon which final payment of the Certificates of such Series will be made upon
presentation and surrender of such Certificates at the office of the
Certificate Trustee 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 such Certificate Trustee
therein specified.

       (e)    If the option of BSMCC or its designee or the Depositor, as the
case may be, to repurchase or cause the repurchase of all Mortgage Loans in a
Mortgage Loan Group under Section 10.01(a)(i) above is exercised, BSMCC, its
designee or the Depositor, as the case may be, shall deliver to the Certificate
Trustee for deposit in the Certificate Account, by the Business Day prior to
the applicable Distribution Date, an amount equal to the repurchase price for
the Mortgage Loans being purchased by it and all property acquired with respect
to such Mortgage Loans remaining in the applicable Trust Fund.  Upon the
presentation and surrender of the related Certificates, the Certificate Trustee
shall distribute all amounts in the Certificate Account related to such
Mortgage Loan Group to the related Certificateholders.  Upon deposit of the
required repurchase price and following such final Distribution Date, the
Certificate Trustee shall cause the Custodian to release promptly to BSMCC or
its designee or the Depositor, as the case may be, the Mortgage Files for the
remaining Mortgage Loans for such Mortgage Loan Group, and upon the termination
of the final Trust created hereunder the Accounts shall terminate, subject to
the Certificate Trustee's obligation to hold any amounts payable to
Certificateholders in trust without interest pending final distributions
pursuant to this Section 10.01.





                                       66
<PAGE>   71
       (f)    In the event that this Agreement is terminated by reason of the
payment or liquidation of all Mortgage Loans or the disposition of all property
acquired with respect to all Mortgage Loans under Section 10.01(a)(ii) above,
each Master Servicer shall deliver to the Certificate Trustee for deposit in
the Certificate Account all distributable amounts remaining in its Protected
Accounts.  Upon the presentation and surrender of the Certificates of the
outstanding Series, the Certificate Trustee shall distribute to the related
Certificateholders, in accordance with their respective interests, all
distributable amounts remaining in the Certificate Account.  Upon deposit by
each Master Servicer of such distributable amounts and delivery to the
Certificate Trustee of an Officer's Certificate from such Master Servicer
certifying that such deposit has been made, and following such final
Distribution Date, the Certificate Trustee shall cause the Custodian to release
promptly to BSMCC or its designee or the Depositor, as the case may be, the
Mortgage Files for the remaining Mortgage Loans, and the Accounts shall
terminate, subject to the Certificate Trustee's obligation to hold any amounts
payable to the Certificateholders in trust without interest pending final
distributions pursuant to this Section 10.01.

       (g)    If not all of the Certificateholders of an affected Series shall
surrender their Certificates for cancellation within six months after the time
specified in the above-mentioned written notice, the Certificate Trustee shall
give a second written notice to the remaining Certificateholders of such Series
to surrender their Certificates for cancellation and receive the final
distribution with respect thereto.  If within six months after the second
notice, not all such Certificates shall have been surrendered for cancellation,
the Certificate Trustee may take appropriate steps, or appoint any agent to
take appropriate steps, to contact the remaining affected Certificateholders
concerning surrender of their Certificates, and the cost thereof shall be paid
out of the funds and other assets which remain subject to this Agreement.


                                   ARTICLE XI
                            MISCELLANEOUS PROVISIONS

       Section 11.01.  Amendment.  (a)  This Agreement may be amended from time
to time by the Depositor, the Certificate Trustee and the Master Servicers,
without notice to or the consent of any of the Certificateholders, to cure any
ambiguity, to correct or supplement any provisions herein that may be defective
or inconsistent with any other provisions herein, to comply with any changes in
the Code or to make any other provisions with respect to matters or questions
arising under this Agreement which shall not be inconsistent with the
provisions of this Agreement; provided, however, that such action shall not, as
evidenced by an Opinion of Independent Counsel, adversely affect in any
material respect the interests of any Certificateholder.

       (b)    This Agreement may also be amended from time to time by the
Depositor, the Certificate Trustee and the Master Servicers, with the consent
of BSMCC and the Holders of Certificates of a Series evidencing Fractional
Undivided Interests aggregating not less than 51% of the Trust Fund for each
affected Series for the purpose of adding any provisions to or changing in any
manner or eliminating any of the provisions of this Agreement or of modifying
in any manner the rights of the Certificateholders of such Series; provided,
however, that no such amendment shall (i) reduce in any manner the amount of,
or delay the timing of, payments received on Mortgage





                                       67
<PAGE>   72
Loans which are required to be distributed on any Certificate of such Series
without the consent of the Holder of such Certificate, (ii) 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 of such Series then outstanding, or (iii) cause any of the
Series REMICs to fail to qualify as a REMIC for federal income tax purposes, as
evidenced by an Opinion of Independent Counsel which shall be provided to the
Certificate Trustee other than at the Certificate Trustee's expense.
Notwithstanding any other provision of this Agreement, for purposes of the
giving or withholding of consents pursuant to this Section 11.02(b),
Certificates registered in the name of or held for the benefit of the
Depositor, the Master Servicers or the Certificate Trustee or any Affiliate
thereof shall be entitled to vote their Undivided Fractional Interests with
respect to matters affecting such Certificates.

       (c)    Promptly after the execution of any such amendment, the
Certificate Trustee shall furnish a copy of such amendment or written
notification of the substance of such amendment to each Certificateholder, with
a copy to the Rating Agencies.

       (d)    In the case of an amendment under Section 11.02(b) above, it
shall not be necessary for the Certificateholders of the affected Series to
approve the particular form of such an amendment.  Rather, it shall be
sufficient if the Certificateholders approve the substance of the amendment.
The manner of obtaining such consents and of evidencing the authorization of
the execution thereof by Certificateholders shall be subject to such reasonable
regulations as the Certificate Trustee may prescribe.

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

       Section 11.02.  Recordation of Agreement.  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 Mortgaged Properties are
situated, and in any other appropriate public recording office or elsewhere.
The Certificate Trustee shall effect such recordation, at the expense of the
Trusts upon the request in writing of a Certificateholder, but only if such
direction is accompanied by an Opinion of Counsel (provided at the expense of
the Certificateholder requesting recordation) to the effect that such
recordation would materially and beneficially affect the interests of the
Certificateholders or is required by law.

       Section 11.03.  Limitation on Rights of Certificateholders.

       (a)    The death or incapacity of any Certificateholder shall not
terminate this Agreement or any Trust, 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, nor
otherwise affect the rights, obligations and liabilities of the parties hereto
or any of them.





                                       68
<PAGE>   73
       (b)    Except as expressly provided in this Agreement, no
Certificateholders shall have any right to vote or in any manner otherwise
control the operation and management of any Trust, or the obligations of the
parties hereto, nor shall anything herein set forth, or contained in the terms
of the Certificates, be construed so as to establish the Certificateholders
from time to time as partners or members of an association; nor shall any
Certificateholders be under any liability to any third Person by reason of any
action taken by the parties to this Agreement pursuant to any provision hereof.

       (c)    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, under or with respect to this Agreement against the
Depositor, the Master Servicers or any successor to any such parties unless (i)
such Certificateholder previously shall have given to the Certificate Trustee a
written notice of a continuing default, as herein provided, (ii) the Holders of
Certificates of a Series evidencing Fractional Undivided Interests aggregating
not less than 51% of the Trust Fund for such Series shall have made written
request upon the Certificate Trustee to institute such action, suit or
proceeding in its own name as Certificate Trustee hereunder and shall have
offered to the Certificate Trustee such reasonable indemnity as it may require
against the costs and expenses and liabilities to be incurred therein or
thereby, and (iii) the Certificate 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.

       (d)    No one or more Certificateholders shall have any right by virtue
of any provision of this Agreement to affect the rights of any other
Certificateholders or to obtain or seek to obtain priority or preference over
any other such Certificateholder, or to enforce any right under this Agreement,
except in the manner herein provided and for the equal, ratable and common
benefit of all Certificateholders.  For the protection and enforcement of the
provisions of this Section 11.03, each and every Certificateholder and the
Certificate Trustee shall be entitled to such relief as can be given either at
law or in equity.

       Section 11.04.  Acts of Certificateholders.

       (a)    Any request, demand, authorization, direction, notice, consent,
waiver or other action provided by this Agreement to be given or taken by
Certificateholders may be embodied in and evidenced by one or more instruments
of substantially similar tenor signed by such Certificateholders in person or
by an agent duly appointed in writing.  Except as herein otherwise expressly
provided, such action shall become effective when such instrument or
instruments are delivered to the Certificate Trustee and, where it is expressly
required, to the Depositor.  Proof of execution of any such instrument or of a
writing appointing any such agent shall be sufficient for any purpose of this
Agreement and conclusive in favor of the Certificate Trustee and the Depositor,
if made in the manner provided in this Section 11.04.

       (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 a certificate of a 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.  Where
such execution is by a signer acting in a capacity other than his or her
individual capacity, such certificate





                                       69
<PAGE>   74
or affidavit shall also constitute sufficient proof of his or her authority.
The fact and date of the execution of any such instrument or writing, or the
authority of the individual executing the same, may also be proved in any other
manner which the Certificate Trustee deems sufficient.

       (c)    The ownership of Certificates (notwithstanding any notation of
ownership or other writing on such Certificates, except an endorsement in
accordance with Section 5.03 made on a Certificate presented in accordance with
Section 5.04) shall be proved by the Certificate Register, and none of the
Certificate Trustee, the Depositor, any Master Servicer or any successor to any
such parties shall be affected by any notice to the contrary.

       (d)    Any request, demand, authorization, direction, notice, consent,
waiver or other action of the Holder of any Certificate shall bind every future
holder of the same Certificate and the Holder of every Certificate issued upon
the registration of transfer or exchange thereof, if applicable, or in lieu
thereof with respect to anything done, omitted or suffered to be done by the
Certificate Trustee, the Depositor, the Master Servicer, the Custodian, or any
of them, or any successor to any such party in reliance thereon, whether or not
notation of such action is made upon such Certificates.

       (e)    In determining whether the Holders of the requisite percentage of
Certificates evidencing Fractional Undivided Interests have given any request,
demand, authorization, direction, notice, consent or waiver hereunder, unless
all Certificates are owned by the Certificate Trustee, Certificates owned by
the Certificate Trustee, the Depositor, the Master Servicers or any sub-
servicer engaged by a Master Servicer or any Affiliate thereof shall be
disregarded, except as otherwise provided in Section 11.01(b) and except that,
in determining whether the Certificate Trustee shall be protected in relying
upon any such request, demand, authorization, direction, notice, consent or

           evidencing a beneficial interest in a pool of conventional

                              referred to below by

                or obligation of CMC Securities Corporation III,
               Bank of America, FSB, Cendant Mortgage Corporation
                     or The First National Bank of Chicago)


No. 0001                                            100/100th Undivided Interest

       This certifies that THE FIRST NATIONAL BANK OF CHICAGO, is the
registered owner of a 100/100th fractional undivided interest in a pool of
conventional one- to four-family residences and individual condominium unit
mortgage loans (the "Mortgage Loans") in the loan group (the "Mortgage Loan
Group") assigned to the series (the "Series") of mortgage pass-through
certificates (the "Certificates") referred to above  and transferred to the
Certificate Trustee referred to below by CMC Securities Corporation III ("CMCSC
III").  The Mortgage Loan Group was created pursuant to a Pooling and Servicing
Agreement dated as of March 1, 1998 (the "Agreement") among CMCSC III, Bank of
America, FSB and Cendant Mortgage Corporation, as master servicers
(collectively, the Master Servicers"), and The First National Bank of Chicago,
as certificate trustee (the "Certificate Trustee"), a summary of certain of the
pertinent provisions of which is set forth hereinbelow.  Mortgage Loans having
an aggregate principal amount of $________ as of March 1, 1998 (the "Cut-Off
Date"), after deducting all payments due on or before the Cut-Off Date, were
transferred and assigned to the Mortgage Loan Group for this Series. This
Certificate is issued under and is subject to the terms, provisions and
conditions of the Agreement, to which Agreement the holder of this Certificate
by virtue of the acceptance hereof assents and by
<PAGE>   86
which such holder is bound.  Capitalized terms not defined herein shall have
the meanings set forth in the Agreement.

       Pursuant to the Agreement, the Certificate Trustee will distribute on
the 25th day of the month, or if such day is not a Business Day, then the next
succeeding Business Day, beginning in April 1998 (each, a "Distribution Date"),
to the Person in whose name this Certificate is registered on the last Business
Day of the month immediately preceding the month of such Distribution 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 1998-1 Certificates pursuant to
Section 6.01 of the Agreement.  For the purposes hereof, amounts received in
connection with the liquidation of defaulted Mortgage Loans in the Mortgage
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
Mortgage Loan Group.

       Distributions on this Certificate will be made by the Certificate
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 Certificate Trustee and such Person. Notwithstanding the above, the final
distribution on this Certificate will be made after due notice by the
Certificate 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 Certificate Trustee in the City of Chicago,
in the State of Illinois.

       Unless the certificate of authentication hereon has been executed by the
Certificate 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 III, the Master Servicers, or the Certificate Trustee and are not insured
or guaranteed by any governmental agency or other entity.  The Certificates are
limited in right of payment to certain collections and recoveries respecting
the Mortgage Loans in the Mortgage 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 Certificate Trustee from time to time for purposes other
than distributions to Certificateholders, such purposes including reimbursement
to the related Master Servicers of certain expenses incurred, by them in
connection with the Mortgage Loans in the Mortgage 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 Servicers and the rights of the
Certificateholders of this Series under the Agreement at any time by CMCSC III,
the Master Servicers and the Certificate Trustee with the consent of BSMCC and
the

       (a)    the Mortgage creates a first lien or a first priority ownership
interest in the estate in fee simple in real property securing the related

having priority over the first lien of the Mortgage subject only to (1) the
lien of non-delinquent current real property taxes and assessments not yet due
and payable, (2) covenants, conditions and restrictions, rights of way,
easements and other matters of public record as of the date of recording which

are referred to or otherwise considered in the appraisal made for the
originator of the Mortgage Loan, or (B) which do not adversely affect the
appraised value of the Mortgaged Property as set forth in such appraisal, and
(3) other matters to which like properties are commonly subject which do not
materially interfere with the benefits of the security intended to be provided
by the Mortgage or the use, enjoyment, value or marketability of the related
Mortgaged Property;

       (b)    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

included in the Mortgage File; and no other instrument of waiver, alteration or
modification has been executed, and no Mortgagor has been released, in whole or

respects;

       (e)    subject to permitted exceptions set forth in (a), the Mortgage is

genuine and each is the legal, valid and binding obligation of the maker
