                INDENTURE, dated as of June 1, 1997 (as amended or supplemented
from time to time as permitted hereby, the "Indenture"), between Sequoia
Mortgage Trust 1 (herein, together with its permitted successors and assigns,
called the "Issuer"), a statutory business trust created under the Deposit Trust
Agreement (as defined herein), and First Union National Bank, a national banking
association, as trustee (together with its permitted successors in the trusts
hereunder, the "Trustee").

                              PRELIMINARY STATEMENT

                The Issuer has duly authorized the execution and delivery of
this Indenture to provide for its Collateralized Mortgage Bonds, (the "Bonds"),
issuable as provided in this Indenture. All covenants and agreements made by the
Issuer herein are for the benefit and security of the Holders of the Bonds and
MBIA. The Issuer is entering into this Indenture, and the Trustee is accepting
the trusts created hereby, for good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged.

                All things necessary to make this Indenture a valid agreement of
the Issuer in accordance with its terms have been done.

                                 GRANTING CLAUSE

                The Issuer hereby Grants to the Trustee, for the exclusive
benefit of the Holders of the Bonds and MBIA, all of the Issuer's right, title
and interest in and to (a) the Pledged Mortgages identified in Schedule A to
this Indenture, including the related Mortgage Documents, which the Issuer has
caused to be delivered to the related Custodian herewith, and all interest and
principal received or receivable by the Issuer on or with respect to the Pledged
Mortgages after the Cut-Off Date and all interest and principal payments on the
Pledged Mortgages received prior to the Cut-off Date in respect of installments
of interest and principal due thereafter, but not including payments of interest
and principal due and payable on the Pledged Mortgages on or before the Cut-off
Date, and all other proceeds received in respect of such Pledged Mortgages, (b)
the Issuer's rights under


<PAGE>   15
the Mortgage Loan Purchase Agreement, the Management Agreement, the Master
Servicing Agreement, the Servicing Agreements and the Purchase and Sale
Agreements (c) the Insurance Policies, (d) all cash, instruments or other
property held or required to be deposited in the Bond Account or the
Distribution Account (exclusive of any earnings on investments made with funds
deposited in the Distribution Account or the Bond Account), (e) property that
secured a Pledged Mortgage that has become an REO property, and (f) all proceeds
of the conversion, voluntary or involuntary, of any of the foregoing into cash
or other liquid assets, including, without limitation, all Insurance Proceeds,
Liquidation Proceeds and condemnation awards. Such Grants are made, however, in
trust, to secure the Bonds equally and ratably without prejudice, priority or
distinction between any Bond and any other Bond by reason of difference in time
of issuance or otherwise, and for the benefit of MBIA and to secure (i) the
payment of all amounts due on the Bonds in accordance with their terms, (ii) the
payment of all other sums payable under this Indenture with respect to the
Bonds, (iii) compliance with the provisions of this Indenture, all as provided
in this Indenture and to secure all amounts due by the Issuer to MBIA, including
the obligations of the Issuer to MBIA under this Indenture, the Master Servicing
Agreement and the Insurance Agreement. All terms used in the foregoing granting
clauses that are defined in Section 1.01 are used with the meanings given in
said Section.

                The Trustee acknowledges such Grant, accepts the trusts
hereunder in accordance with the provisions of this Indenture and agrees to
perform the duties herein required to the best of its ability to the end that
the interests of the Holders of the Bonds and MBIA may be adequately and
effectively protected.

                The Trustee agrees that it will hold the MBIA Policy in trust
and that it will hold any proceeds of any claim made upon the MBIA Policy,
solely for the use and benefit of the Bondholders in accordance with the terms
hereof and of the MBIA Policy.

<PAGE>   39
                Bonds of each Class shall constitute Book Entry Bonds as set
forth in Section 2.13 hereof. The Bonds shall be issued in two Classes, the
Class A-1 Bonds and the Class A-2 Bonds. The aggregate principal amount of Bonds
that may be authenticated and delivered under this Indenture is limited to
$334,347,000 with respect to the Class A-1 Bonds and $200,000,000 with respect
to the Class A-2 Bonds, except for Bonds authenticated and delivered upon
registration of, transfer of or in exchange for, or in lieu of Bonds pursuant to
Sections 2.06, 2.07 and 2.08 hereof.

                All of the Bonds shall be issued in the appropriate forms
attached as Exhibits hereto with such additions and completions as are
appropriate for each such Class.

                The final installments of principal of the Classes of Bonds
shall be payable at the Stated Maturity. 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 or
call for redemption or otherwise. For each Payment Date prior to the Stated
Maturity, the aggregate amount of each installment of principal due and payable
on each Class of Bonds shall be equal to such Class's pro rata share of the
Principal Payment Amount 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, then, if applicable, to any Bondholders' Interest Carryover then to the
principal thereof.

        (b)     Payments of Principal of and Interest on the Bonds.

                On each Payment Date, the Trustee shall withdraw Net Available
Funds (and any amounts on deposit pursuant to claims under the MBIA Policy) from

as applicable, in the respective amounts and order of priority set forth in
Section 3(f)(vi) and (vii) of the Master Servicing Agreement, in each case, to
the extent of funds remaining.

                All payments on the Bonds shall be made pro rata among all Bonds
and as between the Class A-1 and Class A-2 Bonds shall be made, pro rata, in the
case of interest, in the proportion


                II-4
<PAGE>   40
that the Class A-1 Interest Payment Amount and the Class A-2 Interest Payment
Amount, respectively, bear to each other, in case of Bondholders' Interest
Carryover, in the proportion that the Class A-1 Bondholders' Interest Carryover
and the Class A-2 Bondholders' Interest Carryover, respectively, bear to each
other, and, in the case of principal, in the proportion that the Principal
Amount of each such Class bears to each other.

SECTION 2.04. DENOMINATIONS.

                Each Class of Book Entry Bonds shall be evidenced initially by a
single Bond representing the entire aggregate Principal Amount of such Class of
Bonds as of the Closing Date, beneficial ownership of which may be held in
denominations representing Principal Amounts of $1,000 and in multiples of
$1,000 in excess thereof. All of the Book Entry Bonds shall be initially
registered on the Bond Register in the name of Cede & Co., the nominee of the
Depository, and no Beneficial Owner will receive a Definitive Bond representing

SECTION 2.05. EXECUTION, AUTHENTICATION, DELIVERY AND DATING.

                The Bonds shall be executed by an Authorized Officer in the name
and on behalf of the Issuer. The signature of such officer on the Bonds may be
manual or facsimile.

                Bonds bearing the manual or facsimile signature of an individual
who was at any time an Authorized Officer shall bind the Issuer, notwithstanding
that such individual has ceased to hold such office prior to the authentication
and delivery of such Bonds or did not hold such office 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 on behalf of
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 authenticated on the Closing Date shall be dated the
Closing Date. All other Bonds which are authenticated after the Closing Date for
any other purpose hereunder shall be dated the date of their authentication.

<PAGE>   41
                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 by the manual signature
of one of its authorized officers or employees, and such certificate upon any
Bond shall be conclusive evidence, and the only evidence, that such Bond has
been duly authenticated and delivered hereunder.

SECTION 2.06. TEMPORARY BONDS.

                So long as the Book Entry Bonds are held by the Depository for
the Participants in book-entry form, they may be typewritten or in any other
form acceptable to the Issuer, the Trustee and the Depository. At any time
during which the Book Entry Bonds are not held by the Depository for the
Participants in book-entry form, the Definitive Bonds shall be lithographed or
printed with steel engraved borders.

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

                If temporary Bonds are issued, the Issuer will cause definitive
Bonds to be prepared without unreasonable delay. After the preparation of
definitive Bonds, the temporary Bonds shall be exchangeable for definitive Bonds
upon surrender of the temporary Bonds at the office or agency of the Issuer to
be maintained as provided in Section 3.02, 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 Class and of authorized
denominations. Until so exchanged, the temporary Bonds shall in


                                      II-6
<PAGE>   42
all respects be entitled to the same benefits under this Indenture as Definitive
Bonds of the same Class.

SECTION 2.07. 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.

                At any time the Trustee is not also the Bond Registrar, the
Trustee shall be a co-Bond Registrar. The Issuer shall cause each co-Bond
Registrar to furnish the Bond Registrar, 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 so held.

                Upon surrender for registration of transfer of any Bond at the
office or agency of the Issuer to be maintained as provided in Section 3.02, the
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 and of a like aggregate principal amount and Class.

                At the option of the Holder, Bonds may be exchanged for other
Bonds of any authorized denominations, and of a like aggregate initial principal
amount and Class, upon surrender of the Bonds to be exchanged at such office or
agency. Whenever any Bonds are so surrendered for exchange, the Issuer shall
execute,


                                      II-7
<PAGE>   43
and the Trustee shall authenticate and deliver, the Bonds which the Bondholder
making the exchange is entitled to receive.

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

                Every Bond presented or surrendered for registration of transfer
or exchange shall be duly endorsed, or be accompanied by a written instrument of
transfer in form satisfactory to the 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 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 2.08 not involving any transfer.

SECTION 2.08. 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 the Trustee and MBIA to save the Issuer and MBIA and the
Trustee harmless, then, in the absence of notice to the Issuer or the Trustee
that such Bond has been acquired by a bona fide purchaser, the Issuer shall
execute and upon its request the Trustee shall authenticate and deliver, in
exchange for or in lieu of any such mutilated, destroyed, lost or stolen Bond, a
new Bond or Bonds of the same tenor, aggregate initial principal amount and
Class bearing a number not contemporaneously outstanding. If, after the delivery
of such new Bond, a bona fide purchaser of the original Bond in lieu of which
such new Bond was issued presents for payment such original Bond, the Issuer and
the Trustee shall be entitled to recover such new Bond from the person to whom
it was delivered or any person taking therefrom, except a bona fide purchaser,
and shall be entitled to recover upon the security or indemnity provided
therefor to the


                                      II-8
<PAGE>   44
extent of any loss, damage, cost or expenses incurred by the Issuer or the
Trustee in connection therewith. If any such mutilated, destroyed, lost or
stolen Bond shall have become or shall be about to become due and payable, or
shall have become subject to redemption in full, instead of issuing a new Bond,
the Issuer may pay such Bond without surrender thereof, except that any
mutilated Bond shall be surrendered.

                Upon the issuance of any new Bond under this Section, the Issuer
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) 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 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 2.09. PAYMENTS OF PRINCIPAL AND INTEREST; PRINCIPAL AND INTEREST RIGHTS
              RESERVED.

        (a)     The Bonds of each Class shall bear interest for each Interest
Accrual Period at the Bond Interest Rate for the Bonds of such Class, which
interest shall be due and payable on each Payment Date on the unpaid principal
amount of the Bonds of such Class commencing on the Closing Date and continuing
on each Payment Date thereafter until the entire unpaid principal amount of the
Bonds of such Class is paid, whether by acceleration or otherwise, and (to the
extent lawful and enforceable) shall bear interest on overdue interest at the
Bond Interest Rate for the Bonds of such Class all as specified herein, in the
forms of the Bonds and in the Master Servicing Agreement. In addition, in the
circumstances specified in the Master Servicing Agreement, Bondholders' Interest
Carryover may accrue with respect to the


                                      II-9
<PAGE>   45
Bonds which shall be payable as specified herein, in the forms of the Bonds and
in the Master Servicing Agreement.

        The principal of the Bonds shall be payable as specified herein, in the
forms of the Bonds and in the Master Servicing Agreement until the entire unpaid
principal balance of the Bonds of such Series is paid.

        (b)     Each payment of principal of and interest on, and any
Bondholders' Interest Carryover with respect to, a Book Entry Bond shall be paid
to the Depository, which shall credit the amount of such payments to the
accounts of its Depository Participants in accordance with its normal
procedures. Each Depository Participant shall be responsible for disbursing such
payments to the Beneficial Owners of the Book Entry Bonds that it represents and
to each indirect participating brokerage firm (a "brokerage firm" or "indirect
participating firm") for which it acts as agent. Each brokerage firm shall be
responsible for disbursing funds to the Beneficial Owners of the Book Entry
Bonds that it represents. All such credits and disbursements are to be made by
the Depository and the Depository Participants in accordance with the provisions
of the Bonds. Neither the Trustee, the Bond Registrar, MBIA nor the Issuer shall
have any responsibility for such credits and disbursements.

        Each payment of principal of and interest on, and any Bondholders'
Interest Carryover with respect to, a Definitive Bond 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 the applicable Payment Date by
check mailed to such Person's address as it appears in the Bond Register on such
Record Date, except for the final installment of principal payable with respect
to such Bond, which shall be payable as provided in Section 2.09(c).

        All payments of principal of and interest on, and any Bondholders'
Interest Carryover with respect to, the Bonds shall be made only from the Trust
Estate and any other assets of the Issuer, and each Holder of the Bonds, by its
acceptance of the Bonds, agrees that it will have recourse solely against such
Trust Estate and such other assets of the Issuer and that neither the Owner
Trustee in its individual capacity, the Owner nor any of their respective
partners, beneficiaries, agents, officers, 


                                     II-10
<PAGE>   46
directors, employees or successors or assigns shall be personally liable for any
amounts payable, or performance due, under the Bonds or this Indenture.

        (c)     All reductions in the principal amount of a Bond (or one or more
Predecessor Bonds) effected by payments of installments of principal made on any
Payment Date shall be binding upon all Holders of such Bond and any Bond issued
upon transfer thereof or in exchange therefor or in lieu thereof. The final
installment of principal of each Bond (including the Redemption Price of any
Bond called for redemption, 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 3.02. Whenever the
Trustee expects that the entire remaining unpaid principal amount of any Bond
will become due and payable on the next Payment Date, it shall, no later than
five days prior to such Payment Date, mail or cause to be mailed to the Holder
of each Bond as of the close of the business on such otherwise applicable Record
Date a notice to the effect that:

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

                (ii)    if such funds are available, such final installment will
        be payable on such Payment Date, but only upon presentation and
        surrender of such Bond at the office or agency of the Issuer maintained
        for such purpose pursuant to Section 3.02 (the address of which shall be
        set forth in such notice).

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

SECTION 2.10. PERSONS DEEMED OWNERS.

                Prior to due presentment for registration of transfer of any
Bond, the Issuer, MBIA, the Trustee, any Agent and any other agent of the
Issuer, MBIA, or the Trustee shall treat the Person in whose name any Bond is
registered as the owner of such Bond (a) on the applicable Record Date for the
purpose of


                                     II-11
<PAGE>   47
receiving payments of the principal of, and interest on, such Bond and (b) on
any other date for all other purposes whatsoever, whether or not such Bond is
overdue, and neither the Issuer, MBIA, the Trustee, any Agent nor any other
agent of the Issuer or the Trustee shall be affected by notice to the contrary.

SECTION 2.11. CANCELLATION.

                All Bonds surrendered for payment, registration of transfer,
exchange or redemption (unless the Issuer elects not to retire redeemed Bonds)
shall, if surrendered to any Person other than the Trustee, be delivered to the
Trustee and shall be promptly cancelled by it. The Issuer may at any time
deliver to the Trustee for cancellation any Bond previously authenticated and
delivered hereunder which the Issuer may have acquired in any manner whatsoever,
and all Bonds so delivered shall be promptly cancelled by the Trustee. No Bonds
shall be authenticated in lieu of or in exchange for any Bonds cancelled as
provided in this Section, except as expressly permitted by this Indenture. All
cancelled Bonds held by the Trustee shall be held by the Trustee in accordance
with its standard retention policy, unless the Issuer shall direct by an Issuer
Order that they be destroyed or returned to it.

SECTION 2.12. AUTHENTICATION AND DELIVERY OF BONDS.

                The Bonds may be executed by the Issuer and delivered to the
Trustee for authentication, and thereupon the same shall be authenticated and
delivered by the Trustee, provided, that such execution and authentication may
be made in counterpart, upon Issuer Request and upon receipt by the Trustee of
the following:

                (a)     an Issuer Order authorizing the execution,
        authentication and delivery of the Bonds and specifying the Classes, the

        Trustee, complying with the requirements of Section 11.01, reasonably
        satisfactory in form and substance to the Trustee, and to the effect
        that:

                or other collateral, if any, delivered to the Trustee pursuant
                to any subsection of this Section 2.12 is the requisite amount);

                        (iii)   the Bank has corporate power to execute and
                deliver the Deposit Trust Agreement, the Deposit Trust Agreement

                principles relating to or limiting creditors' rights generally
                and such counsel need express no opinion as to the availability
                of equitable remedies;

                        (vi)    the Bonds, when issued, delivered, authenticated
                and paid for, will be the legally valid and binding obligations
                of the Issuer, entitled to the benefits of this Indenture, and
                enforceable against the Issuer in accordance with their terms,
                except as may be limited by bankruptcy, insolvency,

                of equitable remedies;

                        (vii)   assuming due execution and delivery thereof by
                the Trustee and by the Master Servicer, the Master Servicing
                Agreement constitutes the legally valid and binding obligation
                of the Master Servicer and of the Issuer, respectively,
                enforceable against the Master Servicer and the Issuer in
                accordance with its terms, except as may be limited by

                the availability of equitable remedies;

                        (viii)  the Mortgage Notes included in the Original
                Pledged Mortgages have been duly and validly assigned, delivered
                and pledged to the Trustee to the extent contemplated by this
                Indenture, and this Indenture together with such assignment,
                delivery and pledge to the Trustee, creates as security for the
                Bonds a valid and perfected security interest of first priority
                in such Mortgage Notes, except to the extent limited in the
                event (A) the Trustee relinquishes possession of any such
                Mortgage Note, (B) the Depositor, the Issuer, the Master
                Servicer or any 


                                     II-14
<PAGE>   50
                Servicer transfers any such Mortgage Note or the related
                Mortgage to a bona fide purchaser for value without notice prior
                to notification to the Mortgagor of the assignment to the
                Trustee of such Mortgage Note or due recordation of the
                Assignment to the Trustee of the related Mortgage or (C) the
                Depositor, the Issuer, the Master Servicer or any Servicer
                discharges any such Mortgage Note or the related Mortgage prior
                to such notification or recordation; the Mortgages delivered to
                the Trustee with the Original Mortgage Notes will continue to
                secure the Mortgage Notes included in the Original Pledged
                Mortgages, as though, and to the same extent as if, such
                Mortgage Notes had not been assigned, delivered and pledged; and
                it is not necessary to record or file this Indenture or to take
                any other action, except as set forth above, in order to make
                effective the lien and security interest created by this
                Indenture in the Mortgage Notes included in the Original Pledged
                Mortgages;

                        (ix)    this Indenture has been duly qualified under the
                TIA; and

                        (x)     the Issuer's registration statement with respect
                to the Bonds has become effective under the Securities Act of
                1933, as amended, and, to the best of such counsel's knowledge,
                no stop order suspending the effectiveness of such registration
                statement has been issued and is in effect under such act and no
                proceedings for that purpose have been instituted or are pending
                under such act.

                In rendering the opinions set forth above, such counsel may rely
        upon officers' certificates of the Depositor, the Owner Trustee, the
        Issuer, any Servicer, the Master Servicer and the Trustee, without
        independent confirmation or verification, as to the following matters
        and as to such other matters as shall be reasonably acceptable to the
        Trustee: (A) the accuracy of the descriptions of the Mortgage Notes
        included in the Original Pledged Mortgages and the conformity thereof to
        the descriptions in this Indenture, (B) the ownership by Sequoia
        Mortgage Funding Corporation, the Depositor and the Issuer of such
        Mortgage Notes free and clear of any lien, claim, charge or interest of
        any kind of any third party, (C) the physical delivery of such Mortgage


                                     II-15

        such Mortgage Note of any right or interest inconsistent with the
        opinions expressed, and (E) the form of endorsement approved by such
        counsel having been made on each such Mortgage Note. In rendering the
        opinions set forth above, such counsel need express no opinion as to (A)
        the perfection of the security interest in any collateral not governed
        by Article 9 of the Uniform Commercial Code of the State of California
        or New York, (B) the existence of, or the priority of the security
        interest created by the Indenture against, any liens or other interests
        which arise by operation of law and which do not require any filing or
        similar action in order to take priority over a perfected security
        interest or (C) the priority of the security interest created by this
        Indenture with respect to any claim or lien in favor of the United
        States or any agency or instrumentality thereof (including federal tax
        liens and liens arising under Title IV of the Employee Retirement Income
        Security Act of 1974, as amended).

                indenture, mortgage, deed of trust or other agreement or
                instrument to which the Issuer is a party or by which it is
                bound, or any order of any court or administrative agency

                (b)     Each Class of Book Entry Bonds will be issued in the
form of a single typewritten bond certificate (each, a "DTC Certificate") to be
delivered to the Depository by the Issuer substantially in the respective forms
for each such Class attached as Exhibits hereto. The DTC Certificate for each
such Class of Book Entry Bonds shall be initially registered on the Bond
Register in the name of the nominee of such Depository and no Beneficial Owner
will receive a certificate representing its interests in any Class of Book Entry
Bonds except in the event that the Trustee issues Definitive Bonds, as provided
in Section 2.14. Pursuant to the Letter Agreement, while each Class of the Book
Entry Bonds remains outstanding and such Depository remains the Holder, it will
agree to make book-entry transfers among the Depository Participants and receive
and transmit payments of principal and interest on the Book Entry Bonds until
and unless the Trustee authenticates and delivers Definitive Bonds to the
Beneficial Owners of the Book Entry Bonds or their nominees, as described in
Section 2.14.

                (c)     Prior to Book Entry Termination, each Class of Book
Entry Bonds will remain registered in the name of the Depository or its nominee
and at all times: (i) registration of the Book Entry Bonds may not be
transferred by the Trustee or the Bond Registrar except to another Depository;
(ii) the Depository shall maintain book-entry records with respect to the
Beneficial Owners and with respect to ownership and transfers of such Book Entry
Bonds; (iii) ownership and transfers of registration of the Book Entry Bonds on
the books of the Depository shall be governed by applicable rules established by
the Depository; (iv) the Depository may collect its usual and customary fees,
charges and expenses from its Depository Participants; (v) the Trustee shall
deal with the Depository, Depository Participants and interest 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


                                     II-18
<PAGE>   54
inconsistent if they are made with respect to different Beneficial Owners; and
(vi) the Trustee and MBIA may rely and shall be fully protected in relying upon
information furnished by the Depository with respect to its Depository
Participants and furnished by the Depository Participants with respect to
indirect participating firms and Persons shown on the books of such indirect
participating firms as direct or indirect Beneficial Owners.

                All transfers by Beneficial Owners of Book Entry Bonds shall be
made in accordance with the procedures established by the Depository Participant
or brokerage firm representing such Beneficial Owner. Each Depository
Participant shall only transfer Book Entry Bonds of Beneficial Owners it
represents or of brokerage firms for which it acts as agent in accordance with
the Depository's normal procedures.

SECTION 2.14. TERMINATION OF BOOK ENTRY SYSTEM.

                (a)     The book entry system through the Depository with
respect to any Class of Book Entry Bonds may be terminated (a "Book Entry
Termination") upon the happening of any of the following:

                        (i)     The Depository or the Issuer advises the Trustee
                in writing that the Depository is no longer willing or able to
                properly discharge its responsibilities as Depository and the
                Issuer is unable to locate a qualified successor clearing agency
                satisfactory to the Trustee and the Issuer;

                        (ii)    The Issuer at its option advises the Trustee in
                writing that it elects to terminate the book entry system
                through the Depository; or

                        (iii)   After the occurrence of an Event of Default (at
                which time the Trustee shall use all reasonable efforts to
                promptly notify each Beneficial Owner through the Depository of
                such Event of Default when such notice shall be given pursuant
                to Section 6.02), the Beneficial Owners of a majority in
                aggregate Principal Amount of the Book Entry Bonds together
                advise the Trustee and the Depository through the 


                                     II-19
<PAGE>   55
                Depository Participants in writing that the continuation of a
                book entry system through the Depository is no longer in the
                best interests of the Beneficial Owners.

                (b)     Upon the occurrence of any event described in subsection
(a) above, the Trustee shall notify all Beneficial Owners, through the
Depository, of the occurrence of any such event and of the availability of
Definitive Bond certificates to Beneficial Owners requesting the same, in an
aggregate Principal Amount representing the interest of each, making such
adjustments and allowances as it may find necessary or appropriate as to accrued
interest, if any, and previous calls for redemption. Definitive Bond
certificates shall be issued only upon surrender to the Trustee of the Book
Entry Bond by the Depository, accompanied by registration instructions for the
Definitive Bond certificates. Neither the Issuer nor the Trustee shall be liable
for any delay in delivery of such instructions and may conclusively rely on, and
shall be protected in relying on, such instructions. Upon issuance of the
Definitive Bond certificates, all references herein to obligations imposed upon
or to be performed by the Depository shall cease to be applicable and the
provisions relating to Definitive Bonds shall be applicable.

                                    COVENANTS

SECTION 3.01. PAYMENT OF BONDS.

                The Issuer will pay or cause to be duly and punctually paid the
principal of, and interest on, the Bonds (and, to the extent applicable,
Bondholders' Interest Carryover accrued thereon) in accordance with the terms of
the Bonds and this Indenture.

SECTION 3.02. 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 and MBIA 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 and MBIA with the address thereof, Bonds may
be so presented and surrendered, and such notices and demands may be made or
served, at the Corporate Trust Office, and the Issuer hereby appoints the
Trustee as its agent to receive all such surrenders, notices and demands.

                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 or at the Corporate Trust
Office of the Trustee and (iii) any designation of an office or


                                     III-1
<PAGE>   57
agency for payment of Bonds shall be subject to Section 3.03. The Issuer will
give prompt written notice to the Trustee and MBIA of any such designation or
rescission and of any change in the location of any such other office or agency.

SECTION 3.03. MONEY FOR BOND PAYMENTS TO BE HELD IN TRUST.

                All payments of amounts due and payable with respect to any
Bonds which are to be made from amounts withdrawn from the Distribution Account
pursuant to Section 8.02(c) or Section 5.08 shall be made on behalf of the
Issuer by the Trustee or by a Paying Agent, and no amounts so withdrawn from the
Distribution Account for payments of Bonds shall be paid over to the Issuer
under any circumstances except as provided in this Section 3.03 or in Section
5.08.

                If the Issuer shall have a Paying Agent that is not also the
Bond Registrar, it shall furnish, or cause the Bond Registrar to furnish, no
later than the fifth calendar day after each Record Date or the first Business
Day after a Record Date applicable to a Payment Date on which the Bonds will be
redeemed in full, a list, in such form as such Paying Agent may reasonably
require, of the names and addresses of the Holders of Bonds and of the number of
Individual Bonds of each Class 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, 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 Distribution Account), such sum to be held in
trust for the benefit of the Persons entitled thereto. Any moneys deposited with
a Paying Agent in excess of an amount sufficient to pay the amounts then
becoming due on the Bonds with respect to which such deposit was made shall,
upon Issuer Order, be paid over by such Paying Agent to the Trustee for
application in accordance with Article VIII.

                Any Paying Agent other than the Trustee shall be appointed by
Issuer Order, subject to MBIA's written consent, provided, that, no MBIA Default
shall have occurred and be continuing. The Trustee is hereby appointed as the
initial


                                     III-2
<PAGE>   58
Paying Agent. The Issuer shall not appoint any Paying Agent which is not, at the
time of such appointment, a depository institution or trust company whose
obligations would be Permitted Investments pursuant to clause (iv) of the
definition of the term "Permitted Investments". 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 on each Payment Date among such Holders in the proportion
        specified in the applicable 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 the 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 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


                                     III-3
<PAGE>   59
                (6)     comply with all requirements of the Code, and all
        regulations thereunder, 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 has 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 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.

                Subject to applicable escheat laws, 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 six years after such amount has
become due and payable to the Holder of such Bond shall be discharged from such
trust and, upon its written request, 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. The Trustee may, but shall not be
required to, 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 3.04. CORPORATE EXISTENCE OF OWNER TRUSTEE.

                (a)     Any corporation or association into which the Owner
Trustee may be merged or with which it may be consolidated, or any corporation
or association resulting from any merger or consolidation to which the Owner
Trustee shall be a party, shall be the successor Owner Trustee 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 Owner
Trustee may seek to retain certain powers, rights and privileges therefore
obtaining for any period of time following such merger or consolidation, to the
contrary notwithstanding.

                (b)     Any successor to the Owner Trustee appointed pursuant to
Section 10.01 of the Deposit Trust Agreement shall be the successor Owner
Trustee 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.

                (c)     Upon any consolidation or merger of or other succession
to the Owner Trustee in accordance with this Section 3.04, the Person formed by
or surviving such consolidation or merger (if other than the Issuer) or the
Person succeeding to the Owner Trustee under the Deposit Trust Agreement may
exercise every right and power of the Owner Trustee, on behalf of the Issuer,
under this Indenture with the same effect as if such Person had been named as
the Owner Trustee herein.

SECTION 3.05. PROTECTION OF TRUST ESTATE.

                (a)     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 the
                Trust Estate;

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


                                     III-5
<PAGE>   61
                        (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 Mortgage Documents; or

                        (v)     preserve and defend title to the Trust Estate
                and the rights of the Trustee, and of the Bondholders and MBIA,
                in the Pledged Mortgages and the other property held as part of
                the Trust Estate against the claims of all Persons and parties.

                The Issuer hereby designates the Trustee its agent and
attorney-in-fact to execute any financing statement, continuation statement or
other instrument required pursuant to this Section 3.05; 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,
however, that the duty of the Trustee to execute any instrument required
pursuant to this Section 3.05 shall arise only if the Trustee has knowledge
pursuant to Section 6.01(d) of the occurrence of a failure of the Issuer to
comply with provisions of this Section 3.05.

                (b)     Except as permitted by Section 8.08, the Trustee shall
not remove any portion of the 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 of the most recent Opinion of Counsel delivered
pursuant to Section 3.06 (or from the jurisdiction in which it was held, or to
which it is intended to be removed, 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 Section 3.06) or cause or permit
ownership or the pledge of any portion of the Trust Estate that consists of
book-entry securities to be recorded on the books of a Person located in a
different jurisdiction from the jurisdiction in which such ownership or pledge
was recorded at such time unless the Trustee and MBIA shall have first received
an Opinion of Counsel to the effect that the lien and security interest created
by this Indenture with respect to such property will continue to be maintained
after giving effect to such action or actions.

the first calendar year commencing more than three months after the Closing

reasonably satisfactory in form and substance to the Trustee and MBIA either
stating that, in the opinion of such counsel, such action has been taken as is
necessary to maintain the lien and security interest created by this Indenture
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 all such actions, if any, that will,
in the opinion of such counsel, be required to be taken to maintain the lien and
security interest of this Indenture with respect to the Trust Estate until May
15 in the following calendar year.

SECTION 3.07. PERFORMANCE OF OBLIGATIONS; MASTER SERVICING AGREEMENT.

                (a)     The Issuer shall punctually perform and observe all of
its obligations and agreements contained in the Deposit Trust Agreement. The
Issuer and the Trustee shall punctually perform and observe all of their
respective obligations and agreements contained in the Master Servicing
Agreement.

                (b)     The Issuer shall not take any action and will use its
reasonable good faith efforts not to permit any action to be taken by others
that would release any Person from any of such Person's covenants or obligations
under any of the Mortgage Documents or under any instrument included in the
Trust Estate, or that would result in the amendment, hypothecation,
subordination, termination or discharge of, or impair the validity or
effectiveness of, any of the Mortgage Documents, except as expressly provided or
permitted in this Indenture and the Master Servicing Agreement or such Mortgage
Document or other instrument or unless such action will not adversely affect the
interests of the Holders of the Bonds and MBIA.

                (c)     The Issuer shall monitor the performance of the Master
Servicer under the Master Servicing Agreement, and shall use its reasonable good
faith efforts to cause the Master 


                                     III-7
<PAGE>   63
Servicer duly and punctually to perform all of its duties and obligations
thereunder. Upon the occurrence of a Master Servicing Default of which an
Authorized Officer of the Issuer has actual knowledge under the Master Servicing
Agreement, the Issuer shall promptly notify the Trustee and MBIA thereof, and
shall, subject to the prior written consent of MBIA, specify in such notice the
action, if any, the Issuer is taking in respect of such Master Servicing
Default. So long as any such Master Servicing Default shall be continuing and
subject to the prior written consent of MBIA, the Trustee may (i) terminate all
of the rights and powers of the Master Servicer pursuant to the applicable
provisions of the Master Servicing Agreement; (ii) exercise any rights it may
have to enforce the Master Servicing Agreement against the Master Servicer;
and/or (iii) waive any such Master Servicing Default under the Master Servicing
Agreement or take any other action with respect to such Master Servicing Default
as is permitted thereunder.

                (d)     Upon any termination by the Trustee of the Master
Servicer's rights and powers pursuant to the Master Servicing Agreement, the
rights and powers of the Master Servicer with respect to the Pledged Mortgages
shall vest in the Trustee and the Trustee shall be the successor in all respects
to the Master Servicer in its capacity as Master Servicer with respect to such
Pledged Mortgages under the Master Servicing Agreement, until the Trustee shall
have appointed, with the consent of the Issuer, such consent not to be
unreasonably withheld, and the Rating Agencies and MBIA, provided, however, with
respect to MBIA such consent shall not be required if a MBIA Default shall have
occurred and be continuing, and in accordance with the applicable provisions of
the Master Servicing Agreement a new Person to serve as successor to the Master
Servicer. With such consent, the Trustee may elect to continue to serve as
successor Master Servicer under the Master Servicing Agreement. Upon appointment
of a successor Master Servicer, the Trustee and such successor Master Servicer
shall enter into a master servicing agreement in a form substantially similar to
the Master Servicing Agreement. In connection with any such appointment, the
Trustee may make such arrangements for the compensation of such successor as it
and such successor shall agree, but in no event shall such compensation of any
successor Master Servicer (including the Trustee) be in excess of that payable
to the Master Servicer under the Master Servicing Agreement.

<PAGE>   64
                (e)     Upon any termination of the Master Servicer's rights and
powers pursuant to the Master Servicing Agreement, the Trustee shall promptly
notify the Issuer, MBIA and the Rating Agencies, specifying in such notice that
the Trustee or any successor Master Servicer, as the case may be, has succeeded
the Master Servicer under the Master Servicing Agreement, which notice shall
also specify the name and address of any such successor Master Servicer.

SECTION 3.08. INVESTMENT COMPANY ACT.

                The Issuer shall at all times conduct its operations so as not
to be subject to the Investment Company Act of 1940, as amended (or any
successor statute), and the rules and regulations thereunder.

SECTION 3.09. NEGATIVE COVENANTS.

        The Issuer shall not:

                (a)     sell, transfer, exchange or otherwise dispose of any

        Indenture or the Master Servicing Agreement;

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

                (c)     engage in any business or activity other than in
        connection with, or relating to, the issuance of the Bonds and the
        Investor Certificate pursuant to this Indenture and the Deposit Trust
        Agreement, respectively, or amend Section 2.03 or Section 10.01 of the
        Deposit Trust Agreement as in effect on the Closing Date without, in
        each case, the consent of MBIA and the consent of the Holders of 662/3%
        of the aggregate Principal Amount of the Bonds then Outstanding;

                (d)     incur any indebtedness or assume or guaranty any
        indebtedness of any Person, except for such indebtedness as 


                                     III-9
<PAGE>   65
        may be incurred by the Issuer in connection with the issuance of the
        Bonds pursuant to this Indenture;

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

                (f)     (i) permit the validity or effectiveness of this
        Indenture or any Grant to be impaired, or permit the lien of this
        Indenture to be amended, hypothecated, subordinated, terminated or
        discharged, or permit any Person to be released from any covenants or
        obligations under this Indenture, except as may be expressly permitted
        hereby, (ii) permit any lien, charge, security interest, mortgage or
        other encumbrance (other than the lien of this Indenture, the lien
        created by Section 8.04 of the Deposit Trust Agreement, as in effect on
        the Closing Date, or any Permitted Encumbrance) to be created on or
        extended to or otherwise arise upon or burden the Trust Estate or any
        part thereof or any interest therein or the proceeds thereof or (iii)
        permit the lien of this Indenture not to constitute a valid perfected
        first priority security interest in the Trust Estate.

SECTION 3.10. ANNUAL STATEMENT AS TO COMPLIANCE.

                On or before 120 days after the end of the first fiscal year of

                (2)     to the best of such officer's knowledge, based on such

Bonds issued hereunder, any one of the following events (whatever the reason for
such Event of Default and whether it shall be voluntary or involuntary or be
effected by operation of law or pursuant to any judgment, decree or order of any
court or any order, rule or regulation of any administrative or governmental

                (3)     if the Issuer shall breach, or default in any material
        respect in the due observance or performance of, any other of its
        covenants in this Indenture and such Default shall continue for a period
        of 30 days (such 30 day period to be automatically extended for 30 days
        upon delivery by the Issuer of an Officers' Certificate setting forth
        the steps being taken and stating the default is curable, to the Trustee

                (4)     if any representation or warranty of the Issuer made in
        this Indenture, or any certificate or other writing delivered pursuant
        hereto or in connection herewith shall prove to be incorrect in any
        material respect as of the time when the same shall have been made and,
        within 30 days (such 30 day period to be automatically extended for 30
        days upon delivery by the Issuer of an Officers' Certificate setting
        forth the steps being taken and stating the default is curable, to the
        Trustee and, provided no MBIA Default has occurred and is continuing, to
        MBIA) after there shall have been given, by registered or certified
        mail, written notice thereof to the Issuer and MBIA by the Trustee, or
        to the Issuer and the Trustee by MBIA, or, during the existence of a
        MBIA Default, by the Holders of Bonds representing more than 50% of the
        aggregate Principal Amount of the Bonds, the circumstance or condition
        in respect of which such representation or warranty was incorrect shall
        not have been eliminated or otherwise cured;

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

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


                                      V-2
<PAGE>   72
        debts become due or the taking of corporate action by the Issuer in
        furtherance of any of the foregoing.

                (a)     [Reserved]

                (b)     Notwithstanding the foregoing, the failure of the Issuer
to pay when and as due any installment of principal of (regardless of the lapse
of any grace period) any Bond shall not constitute an Event of Default hereunder
unless the Principal Amount of the Bonds after application of all available
amounts on deposit in the Distribution Account on a Payment Date exceeds the
Pool Principal Balance with respect to such Payment Date or unless the aggregate
Principal Amount of the Bonds is not paid in full on the Stated Maturity.
Subject to the foregoing, Section 5.01 of the Indenture shall otherwise apply in
all respects to the Bonds.

SECTION 5.02. ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.

                Subject to Section 12.01(a)(vi) hereof, if an Event of Default
occurs and is continuing with respect to the Bonds, then and in every such case
the Trustee or the Holders of Bonds representing more than 50% of the aggregate
Principal Amount of the Bonds may declare all the Bonds to be immediately due
and payable, provided, however, that if a MBIA Default shall have occurred and
is continuing, such declaration may not have occurred prior to the 45th day
after the occurrence of the applicable Event of Default, by a notice in writing
to the Issuer (and to the Trustee if given by Bondholders), and upon any such
declaration such Bonds shall become immediately due and payable in an amount
equal to:

                (i)     the aggregate Principal Amount of all Classes of Bonds,

                (ii)    accrued and unpaid interest at the Class A-1 Interest
        Rate or Class A-2 Interest Rate, as applicable, on the aggregate
        Principal Amounts through the date of acceleration, and

                (iii)   interest (but only to the extent payment thereof shall
        be legally enforceable) on any overdue 


                                      V-3
<PAGE>   73
        installments of interest on the Bonds from the due date of any such
        installments to the date of the acceleration at the Bond Interest Rate
        at which such interest accrued or such lower rate at which payment of
        such interest shall be legally enforceable.

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

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

                        (A)     all payments of principal of, and interest on,
                all Bonds 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

                        (B)     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, other than the nonpayment of the
        principal of Bonds which have become due solely by such acceleration,
        have been cured or waived as provided in Section 5.15.

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

SECTION 5.03. COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY TRUSTEE.

                The Issuer covenants that if an Event of Default shall occur and
be continuing in respect to the Bonds and the Bonds have been declared due and
payable and such declaration and its


                                      V-4
<PAGE>   74
consequences have not been rescinded and annulled, the Issuer will, upon demand
of the Trustee, pay to the Trustee, for the benefit of the Holders of the Bonds:

                        (i)     the amounts specified in the first paragraph of
        Section 5.02, and

                        (ii)    in addition thereto, such further amount as
        shall be sufficient to cover the costs and expenses of collection,
        including the reasonable compensation, expenses, disbursements and
        advances of the Trustee, its agents and counsel.

                If the Issuer fails to pay such amounts forthwith upon such
demand, the Trustee, in its own name and as trustee of an express trust, and at
the direction of MBIA, may institute a Proceeding for the collection of the sums
so due and unpaid, and may prosecute such Proceeding to judgment or final
decree, and may enforce the same against the Issuer or any other obligor upon
the Bonds and collect, out of the Trust Estate (as defined in the Deposit Trust
Agreement), wherever situated, of the Issuer, the moneys adjudged or decreed to
be payable in the manner provided by law; provided, however, that neither the
Bank nor any of its agents, officers, directors, employees, successors or
assigns shall be personally liable for any amounts due under the Bonds or this
Indenture.

                If an Event of Default occurs and is continuing, the Trustee
shall, with the prior written consent of MBIA, or, in the case of a MBIA
Default, the Trustee may proceed to protect and enforce its rights and the
rights of the Bondholders by any Proceedings the Trustee deems appropriate to
protect and enforce any such rights, whether for the specific enforcement of any
covenant or agreement in this Indenture or in aid of the exercise of any power
granted herein, or enforce any other proper remedy, including, without
limitation, instituting a Proceeding prior to any declaration of acceleration of
the Stated Maturity of the Bonds for the collection of all amounts then due and
unpaid on such Bonds, prosecuting such Proceeding to final judgment or decree,
enforcing the same against the Issuer and collecting out of the property,
wherever situated, of the Issuer the moneys adjudged or decreed to be payable in
the manner provided by law.

SECTION 5.04. REMEDIES.

                Subject to the rights of MBIA under Article XII hereof, if an
Event of Default shall have occurred and be continuing and the Bonds have been
declared due and payable and such declaration and its consequences have not been
rescinded and annulled, the Trustee (subject to Section 5.18, to the extent
applicable) may do one or more of the following:

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

                (b)     in accordance with Section 5.18, sell the Trust Estate
        or any portion thereof or rights or interest therein, at one or more
        public or private Sales called and conducted in any manner permitted by
        law;

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

provided, however, subject to the rights of MBIA under Article XII hereof, that
prior to exercising the foregoing, the Trustee shall have consulted with the
Issuer concerning alternative pay down scenarios but in no event shall such
consultation in any way restrict the rights of MBIA to exercise the remedies set
forth in this Section 5.04.

SECTION 5.05. [RESERVED].


SECTION 5.06. TRUSTEE MAY FILE PROOFS OF CLAIM.

                Subject to Article XII hereof, including the rights of MBIA
thereunder, and in case of the pendency of any receivership, insolvency,
liquidation, bankruptcy, reorganization, arrangement,


                                      V-6
<PAGE>   76
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 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 and file
        such other papers or documents and take such other actions as it deems
        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 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 6.07.

                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 5.07. 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 for the ratable benefit of the Holders of the Bonds in respect of which such
judgment has been recovered. Any surplus shall be available, in accordance with
Section 5.08, for the payment of the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel.

SECTION 5.08. APPLICATION OF MONEY COLLECTED.

                If the Bonds have been declared due and payable following an
Event of Default and such declaration and its consequences have not been
rescinded and annulled, any money collected by the Trustee with respect to the
Bonds pursuant to this Article or otherwise and any monies that may then be held
or thereafter received by the Trustee with respect to the Bonds shall be
applied, after payment to the Trustee of such amounts as may be payable to it
under Section 6.07, in the order, at the date or dates fixed by the Trustee and,
in case of the distribution of the entire amount due on account of principal of,
and interest on, such Bonds, upon presentation and surrender thereof:

        Servicer or the Master Servicer in respect of Nonrecoverable Advances or
        Nonrecoverable Master Servicer Advances made by such Servicer or the

                Third: To the payment of the remainder, if any, to the Issuer or
        any other Person legally entitled thereto.

SECTION 5.09. LIMITATION ON SUITS.

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

                (1)     such Holder has previously given written notice to the
        Trustee and MBIA, unless a MBIA Default has occurred and is continuing,
        of a continuing Event of Default;

                (2)     the Holders of Bonds representing more than 50% of the
        aggregate Principal Amount of the Bonds, with the prior written consent
        of MBIA unless there is a MBIA Default, 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
        indemnity in full 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 request has
        been given to the Trustee during such 60-day period by MBIA or the
        Holders of Bonds representing more than 50% of the aggregate Principal
        Amount of the Bonds in the case of a MBIA Default;

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 themselves 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.

SECTION 5.10. UNCONDITIONAL RIGHTS OF BONDHOLDERS TO RECEIVE PRINCIPAL AND
              INTEREST.

                Notwithstanding any other provision in this Indenture, other
than the provisions hereof limiting the right to recover amounts due on a Bond
to recovery from the property of the Issuer, the Holder of any Bond shall have
the right, to the extent permitted by applicable law, which right is absolute
and unconditional, to receive payment of each installment of interest on such
Bond on the respective Stated Maturities of such installments of interest, to
receive payment of each installment of principal of such Bond when due (or, in
the case of any Bond called for redemption, on the date fixed for such
redemption) and to institute suit for the enforcement of any such payment, and
such right shall not be impaired without the consent of such Holder.

SECTION 5.11. RESTORATION OF RIGHTS AND REMEDIES.

                If the Trustee, MBIA 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, MBIA or to such Bondholder, then and in
every such case the Issuer, the Trustee, MBIA 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, MBIA and the Bondholders shall continue as though no such
Proceeding had been instituted.

SECTION 5.12. RIGHTS AND REMEDIES CUMULATIVE.

                No right or remedy herein conferred upon or reserved to the
Trustee, MBIA 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.

<PAGE>   80
SECTION 5.13. 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, MBIA 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 5.14. CONTROL BY BONDHOLDERS.

                Subject to the rights of MBIA under Article XII hereof, the
Holders of Bonds representing more than 50% of the aggregate Principal Amount of
the Bonds shall have the right to direct the time, method and place of
conducting any Proceeding for any remedy available to the Trustee or exercising
any trust or power conferred on the Trustee; provided, however, that:

                (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 the
        Trust Estate shall be by the Holders of Bonds representing the
        percentage of the aggregate Principal Amount of the Bonds specified in
        Section 5.18(b)(1), unless Section 5.18(b)(2) is applicable; and

                (3)     [Reserved];

                (4)     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 6.01, 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 5.15. WAIVER OF PAST DEFAULTS.

                Subject to the rights of MBIA under Article XII hereof, the
Holders of Bonds representing more than 50% of the aggregate


                                      V-11
<PAGE>   81
Principal Amount of the Bonds may waive any past Default hereunder and its
consequences, except a Default:

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

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

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

SECTION 5.16. UNDERTAKING FOR COSTS.

                All parties to this Indenture agree, and each Holder of any Bond
by his or her 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, to any suit instituted by any Bondholder, or group of Bondholders,
holding in the aggregate Bonds representing more than 10% of the aggregate
Principal Amount of the Bonds, 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 any installment of principal of any Bond when due (or, in the
case of any Bond called for redemption, on or after the applicable redemption
date).

SECTION 5.17. WAIVER OF STAY OR EXTENSION LAWS.

                The Issuer covenants (to the extent that it may lawfully do so)
that it will not at any time insist upon, or plead, or in any manner whatsoever
claim or take the benefit or advantage of, any stay or extension of law wherever
enacted, now or at any time hereafter in force, 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 5.18. SALE OF TRUST ESTATE.

                (a)     The power to effect any sale (a "Sale") of any portion
of the Trust Estate pursuant to Section 5.04 shall not be exhausted by any one
or more Sales as to any portion of the Trust Estate remaining unsold, but shall
continue unimpaired until the entire Trust Estate shall have been sold or all
amounts payable on the Bonds and under this Indenture with respect thereto shall
have been paid. The 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, the Trustee shall not in
any private Sale sell or otherwise dispose of the Trust Estate, or any portion
thereof, unless:

                (1)     the Holders of all Bonds consent to, or direct the
        Trustee to make, such 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 Bonds,
        in full payment thereof in accordance with Section 5.08, on the Payment
        Date next succeeding the date of such Sale.

                (3)     [Reserved]


                                      V-13
<PAGE>   83
                The purchase by the Trustee of all or any portion of the Trust
Estate at a private Sale shall not be deemed a Sale or disposition thereof for
purposes of this Section 5.18(b).

                (c)     Unless the Holders of all Bonds have otherwise consented
or directed the Trustee, at any public Sale of all or any portion of the Trust
Estate at which a minimum bid equal to or greater than the amount described in
paragraph (2) of subsection (b) of this Section 5.18 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 the
Trust Estate:

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

                (2)     the 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 as a result of such
        Sale in accordance with Section 5.08 on the Payment Date next succeeding
        the date of such Sale and (B) the expenses of the Sale and of any
        Proceedings in connection therewith which are reimbursable to it,
        without being required to produce the Bonds in order to complete any
        such Sale or in order for the net Sale price to be credited against such
        Bonds, and any property so acquired by the 


                                      V-14
<PAGE>   84
        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 the
        Trust Estate in connection with a Sale thereof;

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

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

SECTION 5.19. ACTION ON BONDS.

                The Trustee's right to seek and recover judgment under this
Indenture shall not be affected by the seeking, obtaining or application of any
other relief under or with respect to this Indenture. Neither the lien of this
Indenture nor any rights or remedies of the Trustee, MBIA or the Holders of
Bonds 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.

                                   THE TRUSTEE

SECTION 6.01. DUTIES OF TRUSTEE.

                (a)     If an Event of Default has occurred and is continuing,
the Trustee shall exercise such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in their exercise, as a
prudent person would exercise or use under the circumstances in the conduct of
his or her own affairs. If a MBIA Default has occurred and is continuing the
Trustee shall use reasonable efforts to locate an additional insurer; provided
that no additional insurance policy to the MBIA Policy shall be accepted unless
the Rating Agencies shall have provided written confirmation that, upon such
policy being in force, the ratings on the Bonds would be in the highest rating
category of each such agency and the Issuer has consented to such additional
insurer.

                (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 shall be read into this Indenture; and

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

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

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


                                      VI-1
<PAGE>   86
                        (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 5.14 or Section 5.18;

                        (4)     The Trustee shall not be liable with respect to
        any action it takes or omits to take in good faith at the direction of
        Bondholders or MBIA.

                (d)     Except with respect to duties of the Trustee prescribed
by the TIA, as to which this Section 6.01(d) shall not apply, for all purposes
under this Indenture, the Trustee shall not be deemed to have notice or
knowledge of any Event of Default described in Section 5.01(2), 5.01(5) or
5.01(6) or any Default described in Section 5.01(3) or 5.01(4) or any Master
Servicing Default or default under the Master Servicing 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, Master Servicing Default or default
is received by the Trustee at the Corporate Trust Office, and such notice
references the Bonds generally, the Issuer, the Trust Estate or this Indenture.

                (e)     No provision of this Indenture shall require the 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. 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 Trust Estate
pursuant to Sections 6.07 and 8.02(d); provided, however, that, except as
provided in the first sentence of this Section 6.01(e), the Trustee shall not
refuse or fail to perform any of its duties hereunder solely as a result of
nonpayment of 


                                      VI-2
<PAGE>   87
its reasonable fees and expenses; and provided further, however, that nothing in
this Section 6.01(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 amounts due the Trustee pursuant to Section
6.07.

                (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 Stated 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 Bondholders and MBIA and the
rights of Bondholders and MBIA shall continue to be governed by the terms of
this Indenture.

SECTION 6.02. NOTICE OF DEFAULT.

                Upon the Trustee obtaining knowledge of the occurrence of any
Default, the Trustee shall transmit by mail to MBIA and all Holders of Bonds
notice of each such Default; provided, however, that except in the case of a
Default of the type described in Section 5.01(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; and provided, further,
that the Trustee shall not withhold such notice from MBIA; and provided,
further, that in the case of any Default of the character specified in Section
5.01(3) or 5.01(4) no such notice to MBIA and Holders of the Bonds shall be
given until at least 30 days after the occurrence thereof. Concurrently with the
mailing of any such notice to MBIA and the Holders of the Bonds, the Trustee
shall transmit by mail a copy of such notice to the Rating Agencies.

SECTION 6.03. RIGHTS OF TRUSTEE.

                Except as otherwise provided in Section 6.01 hereof:

                (a)     the Trustee may rely and shall be protected in acting or
refraining from acting upon any resolution, certificate, statement, instrument,
opinion, report, notice, request, direction, consent, order, bond, note or other
paper or document believed by it to be genuine and to have been signed or
presented by the proper party or parties;

                (b)     any request or direction of the Issuer mentioned herein
shall be sufficiently evidenced by an Issuer Request or Issuer Order, and any
resolution of the board of directors may be sufficiently evidenced by a written
resolution;

                (c)     whenever in the administration of this Indenture the
Trustee shall deem it desirable that a matter be proved or established prior to
taking, suffering or omitting any action hereunder, the Trustee (unless other
evidence be herein specifically prescribed) may, in the absence of bad faith on
its part, rely upon an Officers' Certificate or the Officer's Certificate of the
Master Servicer;

                (d)     the Trustee may consult with counsel, and the written
advice of such counsel or any Opinion of Counsel shall be full and complete
authorization and protection in respect of any action taken, suffered or omitted
by it hereunder in good faith and in reliance thereon;

                (e)     the Trustee shall be under no obligation to exercise any
of the rights or powers vested in it by this Indenture at the request or
direction of any of the Bondholders pursuant to this Indenture, unless such
Bondholders shall have offered to the Trustee reasonable security or indemnity
against the costs, expenses and liabilities which might be incurred by it in
compliance with such request or direction;

                (f)     the Trustee shall not be bound to make any investigation
into the facts or matters stated in any resolution, certificate, statement,
instrument, opinion, report, notice, request, direction, consent, order, bond,
note or other paper or document, but the Trustee, in its discretion may make
such further inquiry or investigation into such facts or matters as it may see
fit, and if the Trustee shall determine to make such 


                                      VI-4
<PAGE>   89
further inquiry or investigation, it shall be entitled, on reasonable prior
notice to the Issuer, to examine the books, records and premises of the Issuer,
personally or by agent or attorney, during the Issuer's normal business hours;
provided that the Trustee shall and shall cause its agents to hold in confidence
all such information except to the extent disclosure may be required by law and
except to the extent that the Trustee, in its sole judgment, may determine that
such disclosure is consistent with its obligations hereunder;

                (g)     the Trustee may execute any of the trusts or powers
hereunder or perform any duties hereunder either directly or by or through
agents or attorneys, provided, however, that the Trustee shall remain liable for
the execution and performance of any powers and duties by the Trustee directly
or by or through agents or attorneys appointed and supervised by the Trustee
hereunder;

                (h)     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;

                (i)     prior to the time that one of its Responsible Officers
obtains actual knowledge of a Master Servicing Default as defined in the Master
Servicing Agreement or a failure by the Master Servicer thereunder which with
notice and the passage of time will become a Master Servicing Default, the
Trustee shall not be responsible for taking action with respect thereto;

                (j)     the Trustee shall not be responsible for supervising,
monitoring or reviewing the Master Servicer's performance of its duties under
the Master Servicing Agreement except to the extent of determining (i) that the
periodic reports, certificates and opinions required to be delivered by the
Master Servicer to it thereunder are delivered in timely fashion and conform to
the requirements of the Master Servicing Agreement and (ii) that the amounts
received by it from the Master Servicer for deposit in the Distribution Account
during any month are as shown in the Master Servicer's report for such month;
and

                (k)     the provisions of this Section, other than clauses (e),
(i) and (j), and of Sections 6.01(b) and (c) shall apply to the Trustee as it
may be Successor Master Servicer under the Master Servicing Agreement.

SECTION 6.04. NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF BONDS.

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

SECTION 6.05. MAY HOLD BONDS.

                The 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 6.08 and 6.13, may otherwise deal with the Issuer or any
Affiliate of the Issuer with the same rights it would have if it were not the
Trustee, Agent or such other agent.

SECTION 6.06. 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. 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 6.07. COMPENSATION AND REIMBURSEMENT.

                The Issuer agrees to indemnify the Trustee and its agents for,
and to hold them harmless against, any loss,


                                      VI-6
<PAGE>   91
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, however that unless a MBIA Default exists, the
Trustee shall notify MBIA of such legal action (provided that the failure to
notify MBIA shall not waive the rights of the Trustee to indemnification) and
such indemnification by the Trustee out of the Bond Account shall be
preconditioned on the Trustee's duty (i) to allow MBIA to control the defense or
settlement of any such action and (ii) to allow MBIA to direct the Trustee with
respect thereto; provided, further, that (a) if MBIA does not assume control of
the defense of any such action within a reasonable period of time after the
filing of such action, the Trustee shall have the right to act on its own in
defending the action until such time as MBIA assumes control of the defense, (b)
the Trustee along with MBIA shall have the right to consent to any counsel hired
to defend the Trustee (which consent of the Trustee shall not be unreasonably
withheld) and (c) the Trustee along with MBIA shall have the right to consent to
any settlement if the amount of such settlement is less than full
indemnification and the Trustee would not be fully released from liability with
respect to such action as a result of such settlement. Any amounts payable to
the Trustee and its agents, in respect of indemnification provided by this
paragraph, or pursuant to any other right of reimbursement from the Bond Account
that the Trustee and its agents, may have hereunder in its capacity as such,
including but not limited to the following paragraph of this Section 6.07, may
be withdrawn by the Master Servicer from the Bond Account and payable to the
Trustee, or its agents, at any time subject to a maximum amount of $150,000 in
any calendar year pursuant to Section 3(f)(iii)(D) of the Master Servicing
Agreement. Any such amounts due to the Trustee, or its agents, in excess of
$150,000 in such calendar year shall be reimbursable to the Trustee pursuant to
Section 3(f)(vii)(G) of the Master Servicing Agreement.

                As security for the performance of the obligations of the Issuer
under this Section, the Trustee shall have a lien ranking junior to the lien of
the Bonds with respect to which any claim of the Trustee under this Section
arose upon all property and funds held or collected as part of the Trust Estate
by the


                                      VI-7
<PAGE>   92
Trustee in its capacity as such payable pursuant to Section 3(f)(viii)(G) of the
Master Servicing Agreement. The Trustee shall not institute any Proceeding
seeking the enforcement of such lien against the Trust Estate unless such
Proceeding is in connection with a Proceeding in accordance with Article V for
enforcement of the lien of this Indenture after the occurrence of an Event of
Default (other than an Event of Default arising solely from the Issuer's failure
to pay amounts due the Trustee under this Section 6.07) and a resulting
declaration of acceleration of Stated Maturity of the Bonds which has not been
rescinded and annulled.

                The Trustee shall be compensated for its services rendered
hereunder pursuant to a separate agreement between it and the Master Servicer
and shall not look to the Issuer therefor.

SECTION 6.08. ELIGIBILITY; DISQUALIFICATION.

                Irrespective of whether this Indenture is qualified under the
TIA, this Indenture shall always have a Trustee who satisfies the requirements
of TIA Sections 310(a)(1) and 310(a)(5). The Trustee shall always have a
combined capital and surplus as stated in Section 6.09. The Trustee shall be
subject to TIA Section 310(b).

SECTION 6.09. TRUSTEE'S CAPITAL AND SURPLUS.

                The Trustee shall at all times have a combined capital and
surplus of at least $50,000,000 or shall be a member of a bank holding company
system, the aggregate combined capital and surplus of which is at least
$50,000,000; provided, however, that the Trustee's separate capital and surplus
shall at all times be at least the amount required by TIA Section 310(a)(2) if
this Indenture is qualified under the TIA. If the Trustee publishes annual
reports of condition of the type described in TIA Section 310(a)(2), its
combined capital and surplus for purposes of this Section 6.09 shall be as set
forth in the latest such report.

SECTION 6.10. RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

                (a)     No resignation or removal of the Trustee and no
appointment of a successor Trustee pursuant to this Article shall 


                                      VI-8
<PAGE>   93
become effective until the acceptance of appointment by the successor Trustee
under Section 6.11.

                (b)     The Trustee may resign at any time by giving written
notice thereof to the Issuer and MBIA. 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.

                (c)     The Trustee may be removed at any time by (1) MBIA or
(2) by Act of the Holders representing more than 50% of the aggregate Principal
Amount of the Bonds, with the prior written consent of MBIA; provided, however,
MBIA shall have no such right if a MBIA Default exists and is continuing,
delivered to the Trustee and to the Issuer.

                (d)     If at any time:

                        (1)     the Trustee shall have a conflicting interest
        prohibited by Section 6.08 and shall fail to resign or eliminate such
        conflicting interest in accordance with Section 6.08 after written
        request therefor by the Issuer, MBIA or by any Bondholder; provided,
        however, that this Section 6.10(d)(1) shall not be operative as part of
        this Indenture unless and until this Indenture is qualified under the
        TIA, and until such qualification this Indenture shall be construed as
        if this Section 6.10(d)(1) were not contained herein; or

                        (2)     the Trustee shall cease to be eligible under
        Section 6.09 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 an Issuer Order may remove the Trustee
or (ii) subject to Section 5.16, MBIA or any Bondholder who has been a bona fide
Holder of a Bond for at least six months may, on behalf of itself and all others
similarly 


                                      VI-9
<PAGE>   94
situated, and with the prior written consent of MBIA unless a MBIA Default
exists and is continuing, petition any court of competent jurisdiction for the
removal of the Trustee and the appointment of a successor Trustee, unless this
Indenture is qualified under the TIA and the Trustee's duty to resign is stayed
as provided in Section 310(b) of the TIA.

                (e)     If the Trustee shall resign, be removed or become
incapable of acting, or if a vacancy shall occur in the office of the Trustee
for any cause, the Issuer, by an Issuer Order and with the prior written consent
of MBIA unless a MBIA Default exists and is continuing, shall promptly appoint a
successor Trustee. If within one year after such resignation, removal or
incapability or the occurrence of such vacancy a successor Trustee shall be
appointed by MBIA or by Act of the Holders of Bonds representing more than 50%
of the aggregate Principal Amount of the Bonds and with the prior written
consent of MBIA unless a MBIA Default exists and is continuing, 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, MBIA or Bondholders and
shall have accepted appointment in the manner hereinafter provided, MBIA or any
Bondholder who has been a bona fide Holder of a Bond for at least six months
may, on behalf of itself and all others similarly situated and with the prior
written consent of MBIA unless a MBIA Default exists and is continuing, petition
any court of competent jurisdiction for the appointment of a successor Trustee.

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

SECTION 6.11. ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

                Every successor Trustee appointed hereunder shall execute,
acknowledge and deliver to the Issuer, MBIA and the retiring Trustee an
instrument accepting such appointment, and thereupon the resignation or removal
of the retiring Trustee


                                     VI-10
<PAGE>   95
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, upon payment of
its charges, execute and deliver an instrument transferring to such successor
Trustee all the rights, powers and trusts of the retiring Trustee, and shall
duly assign, transfer and deliver to such successor Trustee all property and
money held by such retiring Trustee hereunder subject nevertheless to its lien,
if any, provided for in Section 6.07. Upon request of any such successor
Trustee, the Issuer shall execute and deliver any and all instruments for more
fully and certainly vesting in and confirming to such successor Trustee all such
rights, powers and trusts.

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

SECTION 6.12. MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS OF
              TRUSTEE.

                Any corporation into which the Trustee may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which the Trustee shall be a
party, or any corporation succeeding to all or substantially all of the
corporate trust business of the Trustee, shall be the successor of the Trustee
hereunder, provided such corporation shall be otherwise qualified and eligible
under this Article and be acceptable to MBIA, unless a MBIA Default has occurred
and is continuing, 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.


                                     VI-11
<PAGE>   96
SECTION 6.13. PREFERENTIAL COLLECTION OF CLAIM AGAINST ISSUER.

                If this Indenture is qualified under the TIA, the Trustee shall
be subject to TIA Section 311(a), excluding any creditor relationship listed in
TIA Section 311(b), and a 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.

                Subject to the rights of MBIA under Article XII hereof, at any
time or times, for the purpose of meeting the legal requirements of the TIA or
of any jurisdiction in which any of the Trust Estate may at the time be located,
the 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 Principal Amount of the Bonds 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 the Trust Estate, or to act as separate trustee of any such property, in
either case with such powers as may be provided in the instrument of
appointment, and to vest in such Person or Persons in the capacity aforesaid,
any property, title, right or power deemed necessary or desirable, subject to
the other provisions of this Section. If the Issuer does not join in such
appointment within 15 days after the receipt by it of a request to do so, or in
case an Event of Default has occurred and is continuing, the 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. Each notice shall include the name and address of any such
co-trustee or successor trustee.


                                     VI-12
<PAGE>   97
                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 rights, powers, duties and obligations
        hereby conferred or imposed upon the Trustee in respect of any property
        covered by such appointment shall be conferred or imposed upon and
        exercised or performed by the Trustee or by the Trustee and such
        co-trustee or separate trustee jointly, as shall be provided in the
        instrument appointing such co-trustee or separate trustee, except to the
        extent that under any law of any jurisdiction in which any particular
        act is to be performed, the Trustee shall be incompetent or unqualified
        to perform such act, in which event such rights, powers, duties and
        obligations shall be exercised and performed by such co-trustee or
        separate trustee.

                        (3)     The Trustee at any time, by an instrument in
        writing executed by it, with the concurrence of the Issuer evidenced by
        an Issuer Order, may accept the resignation of or remove any co-trustee
        or separate trustee appointed under this Section, and, in case of 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 which has resigned or
        has been removed may be appointed in the manner provided in this
        Section.

                        (4)     No co-trustee or separate trustee shall be
        required to satisfy the eligibility requirements under 


                                     VI-13
<PAGE>   98
        Sections 6.08 and 6.09. 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.

                        (5)     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 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 the authority of an Authenticating Agent appointed after the initial
authentication and delivery of such Bonds) in connection with transfers and
exchanges under Sections 2.06 and 2.07, if any, as fully to all intents and
purposes as though the Authenticating Agent had been expressly authorized by
those Sections to authenticate and deliver Bonds. For all purposes of this
Indenture (other than in connection with the authentication and delivery of
Bonds pursuant to Sections 2.05 and 2.12 in connection with their initial
issuance and for purposes of Section 2.08), 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
6.09 for the Trustee hereunder and has its principal office in the Borough of
Manhattan, City and State of New York.

                Any Authenticating Agent shall also serve as Bond Registrar or
co-Bond Registrar, as provided in Section 2.07. 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


                                     VI-14
<PAGE>   99
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.

                The Trustee agrees, subject to Section 6.01(e), to pay to any
Authenticating Agent from time to time reasonable compensation for its services
and the Trustee shall be entitled to be reimbursed for such payments, subject to
Section 6.07. The provisions of Sections 2.10, 6.04 and 6.05 shall be applicable
to any Authenticating Agent.

SECTION 6.16. PAYMENT OF CERTAIN INSURANCE PREMIUMS.

                Notwithstanding anything to the contrary contained in this
Indenture, the Trustee agrees, for the benefit of the Holders of the Bonds and
MBIA, that, should it fail to receive notice from any Servicer, or the
applicable Insurer, within the


                                     VI-15
<PAGE>   100
time period required pursuant to the related Servicing Agreement, to the effect
that any premiums due with respect to any Insurance Policies the premiums for
which are required to be paid by the Servicer or the Master Servicer from
amounts on deposit in any related escrow account, or required to be advanced by
the related Servicer the Trustee shall proceed with diligence to make inquiries
of the related Servicer, the Master Servicer, the Issuer and the applicable
Insurers as to whether such premiums have been paid at the times set forth in
the related Servicing Agreement. In the event such premiums have not been paid
and the coverage provided under the related Insurance Policy may be interrupted
or adversely affected, the Trustee agrees promptly to pay such premiums from
amounts on deposit in the Distribution Account, pursuant to Section 8.02(d) and
in accordance with its obligations under the applicable provisions of the Master
Servicing Agreement.

other reports (or copies of such portions of any of the foregoing as the

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

           ACCOUNTS, PAYMENTS OF INTEREST AND PRINCIPAL, AND RELEASES

SECTION 8.01. 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 and shall apply it as provided in this Indenture.
Except as otherwise expressly provided herein, if any default occurred in the
making of any payment or performance under any agreement or instrument that is
part of the Trust Estate, the Trustee may 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 hereunder and any
right to proceed thereafter as provided in Article V.

SECTION 8.02. DISTRIBUTION ACCOUNT.

                (a)     On or prior to the Closing Date, the Issuer shall cause
the Master Servicer to establish and maintain, in the name of the Trustee, for
the benefit of the Bondholders, MBIA and the Holder of the Investor Certificate,
the Pledged Accounts as provided in Section 3(f) of the Master Servicing
Agreement.

                (b)     [Reserved.]

                (c)     The Trustee shall establish and maintain, on behalf of
the Bondholders and MBIA, the Distribution Account. The Trustee shall, promptly
upon receipt, deposit in the Distribution Account and retain therein the
following:

                        (i)     the aggregate amount remitted by the Master
                Servicer to the Trustee pursuant to Section 3(f)(iv) of the
                Master Servicing Agreement; and


                                     VIII-1
<PAGE>   105
                        (ii)    any other amounts deposited hereunder which are
                required to be deposited in the Distribution Account.

                In the event that the Master Servicer shall remit any amount not
required to be remitted, it may at any time direct the Trustee to withdraw such
amount from the Distribution Account, any provision herein to the contrary
notwithstanding. Such direction may be accomplished by delivering an Officer's
Certificate to the Trustee which describes the amounts deposited in error in the
Distribution Account. All funds deposited in the Distribution Account shall be
held by the Trustee in trust for the Bondholders and MBIA until disbursed in
accordance with this Indenture or withdrawn in accordance with Section 2.03(b).
In no event shall the Trustee incur liability other than any liability arising
out of its recklessness, bad faith or willful misconduct, for withdrawals from
the Distribution Account at the direction of the Master Servicer.

                (d)     Subject to Sections 5.02 and 5.08, on each Payment Date
and Redemption Date, the Trustee shall distribute all amounts on deposit in the
Distribution Account to Bondholders in respect of the Bonds to the extent of
amounts due and unpaid on the Bonds for principal and interest in the amounts
and in accordance with Section 2.03(b).

SECTION 8.03. GENERAL PROVISIONS REGARDING PLEDGED ACCOUNTS.

                (a)     Each Pledged Account shall relate solely to the Bonds,
the Investor Certificate and to the Pledged Mortgages, Permitted Investments and
other property securing the Bonds. 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,
other than the Distribution Account, in collective accounts maintained by it in
the normal course of its business and containing funds or property held by it
for other Persons (which may include the Issuer or an Affiliate), provided that
such accounts are under the sole control of the Trustee and the Trustee
maintains adequate records indicating the ownership of all such funds or
property and the portions thereof held for credit to each Pledged Account.


                                     VIII-2
<PAGE>   106
                (b)     So long as no Default or Event of Default shall have
occurred and be continuing, all or a portion of the funds in the Pledged
Accounts shall be invested in Permitted Investments and reinvested by the
Trustee upon written direction of Redwood or the Master Servicer, subject to the
provisions of Section 3(f) of the Master Servicing Agreement. The income and
gain (net of any losses) realized from any such investment of funds on deposit
in the Pledged Accounts shall be for the benefit of Redwood or the Master
Servicer as provided in Section 3(f)(ix) of the Master Servicing Agreement and
shall be remitted to it monthly as provided in the Master Servicing Agreement.
The amount of any realized losses in the Pledged Accounts incurred in respect of
any such investments shall promptly be deposited by Redwood or the Master
Servicer, as applicable, in the applicable Pledged Account. The Master Servicer
will not direct the Trustee to make any investment of any funds or to sell any
investment held in any of the Pledged Accounts unless the security interest
Granted and perfected in such account will continue to be perfected in such
investment or the proceeds of such sale, in either case without any further
action by any Person, and, in connection with any direction to the Trustee to
make any such investment or sale, if requested by the Trustee, the Master
Servicer shall deliver to the Trustee an Opinion of Counsel, acceptable to the
Trustee, to such effect.

                (c)     Subject to Section 6.01(c), the Trustee shall not in any
way be held liable by reason of any insufficiency in any of the Pledged Accounts
resulting from any loss on any Permitted Investment included therein except for
losses attributable to the Trustee's failure to make payments on such Permitted
Investments issued by the Trustee, in its commercial capacity as principal
obligor and not as trustee, in accordance with their terms.

                (d)     If (i) the Master Servicer shall have failed to give
investment directions for any funds on deposit in the Pledged Accounts to the
Trustee by 11:00 a.m. Eastern Time (or such other time as may be agreed by the
Master Servicer and Trustee) on any Business Day or (ii) a Default or Event of
Default shall have occurred and be continuing with respect to the Bonds but the
Bonds shall not have been declared due and payable pursuant to Section 5.02 or
(iii) if such Bonds shall have been declared due and payable following an Event
of Default, amounts collected or receivable from the Trust Estate are being
applied 


                                     VIII-3
<PAGE>   107
in accordance with Section 5.05 as if there had not been such a declaration,
then the Trustee shall, to the fullest extent practicable, invest and reinvest
funds in the Pledged Accounts in one or more Permitted Investments.

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

SECTION 8.04. PURCHASES OF DEFECTIVE PLEDGED MORTGAGES; CONVERTED MORTGAGE
              LOANS.

                (a)     If at any time the Issuer, MBIA or the Trustee discovers
or is notified by the Master Servicer (i) that there has been a breach of any of
Redwood's representations and warranties with respect to Pledged Mortgages
contained in the Master Servicing Agreement that materially and adversely
affects the interests of the Bondholders or MBIA in any Pledged Mortgage, (ii)
that any of the Mortgage Documents for a Pledged Mortgage has not been properly
executed by the Mortgagor or contains a material defect or (iii) that any
Mortgage Documents for a Pledged Mortgage shall not have been received by the
Trustee within the applicable time periods and in the forms set forth in Section
3.11 or Section 6.16, as the case may be, and the Master Servicing Agreement,
then the party discovering such defect or omission or receiving notice thereof
shall promptly notify the other parties and the Master Servicer (other than in
cases where the Master Servicer has given notice thereof).

                (b)     If any defect, misrepresentation or omission described
in subsection (a) of this Section 8.04 materially and adversely affects the
interests of the Bondholders or MBIA, then Redwood, on behalf of the Issuer
shall, pursuant to the applicable provisions of the Master Servicing Agreement,
either (i) cure any such defect, misrepresentation or omission, (ii) 


                                     VIII-4
<PAGE>   108
remove such Pledged Mortgage and substitute in its place a Replacement Pledged
Mortgage or (iii) purchase the affected Pledged Mortgage, in each case at the
times and in the manner set forth in the Master Servicing Agreement.

                (c)     Upon any such purchase or substitution, the Issuer shall
be entitled to request a release of the defective Pledged Mortgage from the lien
of this Indenture pursuant to Section 8.08(c) and Section 8.12.

                (d)     If the Issuer or Redwood shall either (i) purchase any
Pledged Mortgage it is required to purchase pursuant to the Master Servicing
Agreement and deposit the Purchase Price therefor in the Bond Account or (ii)
(a) remove such Pledged Mortgage from the Trust Estate and substitute in its
place a Replacement Pledged Mortgage and (b) deposit in the Bond Account any
related Substitution Adjustment Amount, in each case in the manner set forth in
the Master Servicing Agreement, then the Issuer shall be deemed to have complied
with all requirements imposed upon it by this Section 8.04 with respect to such
Pledged Mortgage.

                (e)     Each related Servicer shall, in its sole discretion,
have the right to purchase for its own account from the Trust Estate any Pledged
Mortgage which is 91 days or more delinquent and Redwood shall, pursuant to the
Management Agreement, in its sole discretion, have the right to purchase for its
own account from the Trust Estate any Delinquent Pledged Mortgage, in either
case, at the Purchase Price therefor and in the same manner as that specified
for the purchase of Defective Pledged Mortgages pursuant to Section 2(c)(iv) of
the Master Servicing Agreement. Upon purchase of such Pledged Mortgage by the
related Servicer or Redwood, the Master Servicer and the Issuer shall have the
right to treat such Pledged Mortgage (a "Defaulted Pledged Mortgage") as having
been the subject of a Principal Prepayment in Full and request the release
thereof from the lien of this Indenture pursuant to Section 8.12.

                (f)     With respect to any Converted Mortgage Loan that is
serviced pursuant to a Servicing Agreement that does not require the related
Servicer to purchase or otherwise take any action to effect the purchase of a
Converted Mortgage Loan, Redwood shall, pursuant to the Management Agreement,
repurchase 


                                     VIII-5
<PAGE>   109
such a Converted Mortgage Loan from the Issuer at the Purchase Price therefor on
or prior to the Withdrawal Date for the Prepayment Period during which Redwood
obtained notice of such conversion. With respect to any Converted Mortgage Loan
that is serviced pursuant to a Servicing Agreement that does not require the
related Servicer to purchase a Converted Mortgage Loan but does require
reasonable or other efforts on the part of the Servicer to effect the purchase
of the Converted Mortgage Loan by the related subservicer, Redwood itself shall,
pursuant to the Management Agreement, use reasonable efforts to attempt to
effect the purchase of such a Converted Mortgage Loan from the Issuer; provided,
that Redwood shall have no obligation to purchase any such Converted Mortgage
Loan. With respect to any Converted Mortgage Loan that is serviced pursuant to a
Servicing Agreement that requires the related Servicer to purchase a Converted
Mortgage Loan, neither Redwood or the Issuer shall have any obligation to
purchase such a Converted Mortgage Loan should the related Servicer fail to do
so. Any purchase of a Converted Mortgage Loan by a Servicer, any subservicer or
any other Person shall be at a price which shall not be less than the Purchase
Price therefor. Upon any such purchase of a Converted Mortgage Loan, the Master
Servicer and the Issuer shall have the right to treat such Pledged Mortgage as
having been the subject of a Principal Prepayment in Full and shall request the
release thereof from the lien of this Indenture pursuant to Sections 8.08(c) and
8.12.

SECTION 8.05. GRANT OF REPLACEMENT PLEDGED MORTGAGE.

                The Issuer shall be permitted to substitute any Pledged Mortgage
for any Original Pledged Mortgage initially Granted to the Trustee on the
Closing Date pursuant to this Indenture as set forth in Sections 2(a)(ii) and
2(c)(iv) of the Master Servicing Agreement.

SECTION 8.06. REPORTS BY TRUSTEE TO BONDHOLDERS.

                On each Payment Date, upon receipt from the Master Servicer, the
Trustee shall deliver a Payment Date Statement to each Holder of Bonds.


                                     VIII-6
<PAGE>   110
SECTION 8.07. REPORTS BY TRUSTEE.

                In addition to any statements required to be delivered or
prepared by the Trustee pursuant to Section 2.09, 8.02 or 10.01, the Trustee
shall deliver to the Issuer and MBIA, within two Business Days after the request
of the Issuer or MBIA, a written report setting forth the amount of each Pledged
Account established hereunder and the identity of the investments included
therein. Without limiting the generality of the foregoing, the Trustee shall,
upon the request of the Issuer or MBIA, promptly transmit to the Issuer and MBIA
copies of all accountings of, and information with respect to, collections
furnished to it by the Master Servicer and shall promptly notify the Issuer and
MBIA if on the Payment Date, the related Bond Distribution Amount or any portion
thereof has not been received by the Trustee.

SECTION 8.08. TRUST ESTATE; RELEASE AND DELIVERY OF MORTGAGE DOCUMENTS.

                (a)     The Trustee may, and when required by the provisions of
this Indenture shall, execute instruments in form supplied to it to release
property from the lien of this Indenture, or convey the Trustee's interest in
the same, in a manner and under circumstances which are not inconsistent with
the provisions of this Indenture and the TIA. No party relying upon an
instrument executed by the Trustee as provided in this Article VIII 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.

                (b)     In order to facilitate the servicing of the Pledged
Mortgages by the Servicers, the Master Servicer is authorized under the Master
Servicing Agreement for the benefit of the Trustee, the Bondholders, MBIA and
the Issuer, to supervise, administer, monitor and oversee the servicing of the
Pledged Mortgages by the Servicers and the observance and performance by the
Servicers of all services, duties, responsibilities and obligations which are to
be observed or performed by each Servicer pursuant to the respective Servicing
Agreement.


                                     VIII-7
<PAGE>   111
                (c)     Upon request by a Servicer accompanied by a Request for
Release of Documents in the form of Exhibit Two to the applicable Custodial
Agreement to the effect that a Pledged Mortgage has been the subject of a
Prepayment in Full or has otherwise been paid in full, together with any other
items required under Section 8.12, the Trustee shall promptly request that the
Custodian release the related Mortgage Documents and execute such other
documents as the Servicer may request to evidence satisfaction and discharge of
such Pledged Mortgage.

                (d)     The Trustee shall, at such time as there are no Bonds
Outstanding, release all of the Trust Estate to the Issuer (other than any cash
held for the payment of the Bonds pursuant to Section 3.03 or Section 4.02),
subject, however, to Section 4.01 and the rights of the Trustee under Section
6.07.

SECTION 8.09. AMENDMENTS TO THE MASTER SERVICING AGREEMENT.

                The Trustee may enter into or consent to any amendment or
supplement to the Master Servicing Agreement or waive any Master Servicing
Default only in accordance with the applicable provisions of the Master
Servicing Agreement. The Trustee may, in its discretion, decline to enter into
or consent to any such supplement or amendment or make any such waiver (i)
unless the Trustee receives an Opinion of Counsel that the interests of the
Holders would not be materially adversely affected or (ii) if its own rights,
duties or immunities would be adversely affected.

SECTION 8.10. SERVICERS AND MASTER SERVICER AS AGENTS AND BAILEES OF TRUSTEE.

                In order to facilitate the servicing of the Pledged Mortgages by
the each Servicer or by the Master Servicer, each Servicer shall deposit in a
Servicing Account proceeds of the Pledged Mortgages in accordance with the
provisions of the Servicing Agreements and this Indenture, prior to the time
they are deposited into the Bond Account. In addition, on each Withdrawal Date,
each Servicer shall be required to remit to the Master Servicer for deposit in
the Bond Account all funds held in the related Servicing Account that are
required to be remitted to the Master Servicer in accordance with the terms of
the Servicing Agreement and the Master Servicing Agreement. Solely for purposes
of perfection under Section 9-305 of the Uniform


                                     VIII-8
<PAGE>   112
Commercial Code or similar provision of law in the state in which such property
is held by the Servicers or the Master Servicer, the Trustee hereby designates
the Master Servicer and each Servicer as its agents and bailees to hold such
funds with respect to the Pledged Mortgages until they are deposited into the
Distribution Account as well as its agents and bailees in holding any Mortgage
Documents or other documents contained in a Trustee Mortgage File released to it
by the Custodian pursuant to Section 8.08(d), and any other items constituting a
part of the Trust Estate which from time to time come into possession of any
Servicer or the Master Servicer. It is intended that, by the Servicers' and
Master Servicer's acceptance of such agency pursuant to the Servicing Agreements
and the Master Servicing Agreement, the Trustee, as secured party, will be
deemed to have possession of such Mortgage Documents, such moneys and such other
items for purposes of Section 9-305 of the Uniform Commercial Code or similar
provision of law of the states in which such property is held by such Servicer
or the Master Servicer.

SECTION 8.11. OPINION OF COUNSEL.

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

SECTION 8.12. RELEASE OF PLEDGED MORTGAGES.

                (a)     The Issuer shall be entitled to request a release from
the lien of this Indenture of any Pledged Mortgage at any time after such
Pledged Mortgage has been the subject of a Principal Prepayment in Full or in
accordance with the requirements of Section 8.04 if:

<PAGE>   113
                        (i)     the related Servicer has complied with all
        requirements imposed on it by Section 8.04 in connection with such
        Pledged Mortgage (or is deemed to have complied with such requirements
        by reason of the provisions of Section 8.04(e));

                        (ii)    at the time such release is requested, no
        Default or Event of Default has occurred and is continuing; provided,
        however, that if a Pledged Mortgage has been the subject of a Principal
        Prepayment in Full, then the Trustee shall release such Pledged Mortgage
        from the lien of this Indenture upon compliance with all other
        conditions of this subsection (a), notwithstanding the existence of a
        Default or Event of Default;

                        (iii)   the applicable Servicers, the Issuer or Redwood
        delivers to the Trustee an Officers' Certificate (A) identifying the
        Pledged Mortgage to be released, (B) requesting the release thereof, (C)

        thereto, if any, and (D) certifying that the conditions set forth in
        clauses (i) and (ii) above have been satisfied; and

                        (iv)    the Issuer delivers to the Trustee a certificate
        of fair value if required by Section 314(d)(1) or Section 314(d)(3) of
        the TIA.

                (b)     Upon satisfaction of the conditions specified in
subsection (a) of this Section 8.12, the Trustee shall release from the lien of
this Indenture and deliver to or upon the order of the Issuer the Pledged
Mortgage to be released (including all related Mortgage Documents) described in

without the consent of the Holders of any Bonds, the Issuer 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,

        the interests of the Bondholders and MBIA 


                                      IX-1
<PAGE>   115
        if the Issuer delivers to the Trustee letters from each Rating Agency to
        the effect that such action will not result in a downgrading of the
        Bonds);

                (6)     to modify, eliminate or add to the provisions of this
        Indenture to such extent as shall be necessary to effect the

        insurance policy in the event of a MBIA Default.

                The Trustee is hereby authorized to join in the execution of any
such supplemental indenture and to make any further appropriate agreements and
stipulations that may be therein contained, but the Trustee shall not be
obligated to enter into any such supplemental indenture that affects the
Trustee's own rights, duties, liabilities or immunities under this Indenture or
otherwise except to the extent required by law.

                The Trustee may in its discretion determine whether or not the
rights of the Holder of Bonds would be adversely 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. In making such determination, a supplemental indenture shall be
conclusively deemed by the Trustee not to adversely affect the Bonds if (i) the
Trustee receives a letter or other writing from each Rating Agency rating the
Bonds to the effect that execution of the supplemental indenture will not result
in any change in the current rating assigned by that Rating Agency to the Bonds
(or in the case of clause (7) above; that will not result in the Bonds not being
assigned by each agency the highest credit rating of each agency and (ii) the
supplemental indenture effects no change in principal priority schedules,
interest rates, Redemption Prices, substitution of Mortgage Collateral, Payment
Dates, Record Dates, terms or redemption, the application of surplus to the
payment of the Bonds or other payment terms. The Trustee shall not be liable for
any such determination made in good faith.

                The Trustee shall provide MBIA, if any, with a copy of any
supplemental indenture executed pursuant to this Section, by first class mail
mailed to MBIA within five Business Days after the execution of such
supplemental indenture. Notwithstanding the foregoing, no supplemental indenture
may be entered into without the prior written consent of MBIA (except in the
case of clause (7) above).

SECTION 9.02. SUPPLEMENTAL INDENTURES WITH CONSENT OF BONDHOLDERS.

                Subject to the rights of MBIA under Article XII hereof and with
the consent of the Holders of Bonds representing not less than two-thirds of the
aggregate Principal Amount of the Bonds by Act of said Holders delivered to the
Issuer and the Trustee and MBIA, the Issuer 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 or of modifying in any manner the rights of the Holders of
the Bonds 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 the earliest date on which
        any Bond may be redeemed at the option of the Issuer, change any place
        of payment where, or the coin or currency in which, any Bond or any
        interest thereon is payable, or impair the right to institute suit for
        the enforcement of the payment of any installment of interest due on any
        Bond on or after the 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 Principal Amount
        of the Bonds, the consent of the Holders of which is 


                                      IX-3
<PAGE>   117
        required for any such supplemental indenture, or the consent of the
        Holders of which is required for any waiver of compliance with
        provisions of this Indenture or Defaults hereunder and their
        consequences provided for in this Indenture;

                (3)     modify any of the provisions of this Section, Section
        5.14 or Section 5.18(b) except to increase any percentage specified
        therein or to provide that certain other provisions of this Indenture
        cannot be modified or waived without the consent of the Holder of each
        Outstanding Bond affected thereby;

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

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

                (6)     modify any of the provisions of this Indenture in such
        manner as to materially and adversely affect rights of the Holders of
        the Bonds to the benefits of any provisions for the mandatory redemption
        of Bonds contained herein.

                The Trustee may in its discretion determine whether or not the
rights of the Holder of any Bonds would be materially and adversely affected by
any supplemental indenture and any such determination shall be conclusive upon
the Holders of all Bonds authenticated and delivered hereunder, provided,
however, that unless a MBIA Default has occurred and is continuing, written
consent of MBIA shall be required unless such action shall not, as evidenced by
an Opinion of Counsel delivered to the Trustee and MBIA adversely affect in any
material respect the interests of MBIA. 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


                                      IX-4
<PAGE>   118
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 Trustee shall mail to
the Holders of the Bonds to which such supplemental indenture relates a notice
setting forth in general terms the substance of such supplemental indenture. The
Trustee shall mail to MBIA a copy of any supplemental indenture executed
pursuant to this Section, by first class mail, mailed to MBIA within five
Business Days after the execution of such supplemental indenture. Any failure of
the Trustee to mail such notice, or any defect therein, shall not, however, in
any way impair or affect the validity of any such supplemental indenture.

        SECTION 9.03. EXECUTION OF SUPPLEMENTAL INDENTURES.

                In executing, consenting to 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 and
MBIA, unless a MBIA default has occurred and is continuing, shall be entitled to
receive, and (subject to Section 6.01) shall be fully protected in relying upon,
an Opinion of Counsel stating that the execution of such supplemental indenture
is authorized or permitted by this Indenture. The Trustee may, but shall not be
obligated to, enter into any such supplemental indenture which affects the
Trustee's own rights, duties or immunities under this Indenture or otherwise.
Executed copies of any supplemental indenture permitted by this Article shall be
provided by the Trustee to the Rating Agencies.

SECTION 9.04. EFFECT OF SUPPLEMENTAL INDENTURES.

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

<PAGE>   119
SECTION 9.05. CONFORMITY WITH TRUST INDENTURE ACT.

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

SECTION 9.06. REFERENCE IN BONDS TO SUPPLEMENTAL INDENTURES.

                Bonds authenticated and delivered after the execution of any
supplemental indenture pursuant to this Article may, and if required by the
Trustee 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 the Trustee and the
Issuer, to any such supplemental indenture may be prepared and executed by the
Issuer and authenticated and delivered by the Trustee in exchange for Bonds.

SECTION 9.07. AMENDMENTS TO DEPOSIT TRUST AGREEMENT OR MASTER SERVICING
              AGREEMENT.

                Subject to the rights of MBIA under Article XII hereof, the
Trustee shall, upon Issuer Request, consent to any proposed amendment to the
Deposit Trust Agreement or Master Servicing Agreement, or an amendment to or
waiver of any provision of any other document relating to the Deposit Trust
Agreement or Master Servicing Agreement, such consent to be given without the
necessity of obtaining the consent of the Holders of any Bonds upon receipt by
the Trustee of:

                (i)     an Opinion of Counsel to the effect that such amendment
        or waiver will not materially and adversely affect the interests of the
        Holders of the Bonds and that all conditions precedent to such consent
        specified in this Section 9.07 have been satisfied; provided, however,
        that no such Opinion of Counsel shall be required if the Person
        requesting the amendment obtains a letter from each Rating Agency
        stating that the amendment would not result in the downgrading or
        withdrawal of the respective ratings then assigned to the Bonds; it
        being understood and agreed that any such letter in and of itself will
        not represent a determination as to the materiality of any such
        amendment 


                                      IX-6
<PAGE>   120
        and will represent a determination only as to the credit issues
        affecting any such rating;

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

                (iii)   written confirmation from the Rating Agencies that the
        implementation of the proposed amendment or waiver will not adversely
        affect their rating of the Bonds; and

                (iv)    any other document required pursuant to Section 11.01;

provided, however, amendments to the definitions of Specified
Overcollateralization Amount, Base Specified Overcollateraliz- ation Amount,
Target Percentage and Serious Delinquencies, (each of which is contained in the
Master Servicing Agreement), may be made solely upon (i) the written consent of
the Issuer and MBIA and (ii) advise of tax counsel to the Issuer.

                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 this Indenture or otherwise.

                Nothing in this Section 9.07 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
this Indenture or by the terms of the document that is the subject of the
proposed amendment or waiver.

                               REDEMPTION OF BONDS

SECTION 10.01. REDEMPTION.

                (a)     The Bonds shall not be subject to special redemption.

                (b)     The Bonds shall be subject to redemption by the Issuer,
in whole but not in part, at the option of the Issuer, on any Payment Date on or
after the earlier of (i) seven years after the Closing Date and (ii) the Payment
Date after which the Pool Principal Balance with respect to such Payment Date,
is 35% or less than the Initial Pool Principal Balance, on the terms and
conditions specified in this subsection (b) at the Redemption Price plus all
amounts due to MBIA pursuant to the Insurance Agreement. If the Issuer elects to
so redeem the Bonds, it shall, no later than 30 days prior to the Payment Date
selected for such redemption, deliver notice of such election to the Trustee and
MBIA, together with the Redemption Price therefor plus all amounts due to MBIA
pursuant to the Insurance Agreement to be deposited in the Distribution Account.

                (c)     The Bonds will be subject to mandatory redemption and
retirement by the Issuer at the Redemption Price in the event that the Master
Servicer or the Insurer exercises its option to purchase all of the remaining
Pledged Mortgages. Such option may be exercised by the Master Servicer (or if
the Master Servicer fails to exercise such option, by MBIA) on any Payment Date
after the Payment Date with respect to which the Pool Principal Balance is equal
to 10% or less of the Initial Pool Principal Balance. To exercise such option,
the Master Servicer or MBIA, as the case may be, must solicit and turn over to
the Trustee at least three bids or the remaining Pledged Mortgages each from a
Person that is not an affiliate of the Master Servicer or MBIA. The Trustee
shall accept the highest such bid submitted provided, further, that the price to
be paid for the remaining Pledged Mortgages shall not be less than the
Redemption Price, plus all amounts due to MBIA pursuant to the Insurance
Agreement and plus all other amounts due by the Issuer to, the Trustee, the
Master Servicer, Redwood and plus the amount of any other claims against the
Issuer then outstanding, regardless of whether said claims are 


                                       X-1
<PAGE>   122
enforceable in a court of law or equity. In addition, in order to exercise the
option to purchase the remaining Pledged Mortgages, in the manner set forth
above, prior to soliciting such bids, the Master Servicer or MBIA shall provide
the Issuer with notice 90 days' prior to their exercise of such options.

                (d)     In effecting any redemption pursuant to subsections (b)
or (c), concurrent with the notice provided for therein, the Issuer shall
deliver an Issuer Order directing the Trustee to effect such redemption, any
certification and opinion required pursuant to Section 11.01 and a form of
redemption notice. All Bonds so redeemed shall be due and payable on such
Redemption Date upon the giving of the notice thereof required by Section 10.02.

                (e)     If the Issuer elects to retain and resell the Bonds,
other than to an affiliate, following any redemption pursuant to subsection (b)
of this Section 10.01, the Issuer shall be required to provide, as a condition
precedent to such sale, the opinion set forth in Section 2.12(c) with such
modifications thereto as shall be acceptable to MBIA provided that no MBIA
Default shall have occurred and be continuing.


SECTION 10.02. FORM OF REDEMPTION NOTICE.

                Notice of redemption shall be given by the Trustee in the name
of and at the expense of the Issuer by first class mail, postage prepaid, mailed
not less than thirty days prior to the applicable Redemption Date (but in no
event prior to the date on which the Redemption Price with respect to the Bonds
to be redeemed pursuant to Section 10.01 has been deposited in the Distribution
Account) to MBIA and each Holder of Bonds to be redeemed, such Holders being
determined as of the Record Date with respect to the Payment Date on which such
redemption is to occur.

                All notices of redemption shall state:

                (1)     the Redemption Date; and

                (2)     the fact of such payment in full and the place where
        such Bonds are to be surrendered for payment of the 


                                      X-2
<PAGE>   123
        Redemption Price (which shall be the office or agency of the Issuer to
        be maintained as provided in Section 3.02). Failure to give notice of
        redemption, or any defect therein, to any Holder of any Bond selected
        for redemption shall not impair or affect the validity of the redemption
        of any other Bond.

SECTION 10.03. BONDS PAYABLE ON REDEMPTION DATE.

                Notice of redemption having been given as provided in Section
10.02, the Bonds or portions thereof so to be redeemed shall, on the applicable
Redemption Date, become due and payable at the Redemption Price and (unless the
Issuer shall default in the payment of the Redemption Price or elect not to
retire the Bonds so redeemed, as provided in Section 10.04) no interest shall
accrue on such Redemption Price for any period after the last day preceding the
day on which such Redemption Date occurs.

SECTION 10.04. RETENTION OF BONDS BY ISSUER.

                In the event that the Issuer effects a redemption of the Bonds
in accordance with the provisions of Section 10.01(b), it may elect to cause the
Bonds to remain Outstanding and not release the lien of the Indenture with
respect to the Trust Estate securing such Bonds or terminate such Bonds. If the
Issuer so elects, the Bonds shall not merge with the security therefor, but
shall remain validly Outstanding, subject to the following paragraph and Section
10.01(e).

                Notwithstanding the foregoing, no redemption of any Bond shall
be permitted without retiring it unless the Issuer shall have delivered to the
Trustee and MBIA, provided a MBIA Default has not occurred and is continuing, an
Opinion of Counsel that such redemption without retirement will not adversely
affect the status of any Bond, for federal income tax purposes, as debt of the
Person that is considered the beneficial owner of the Pledged Mortgages.

                                  MISCELLANEOUS

SECTION 11.01. 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, opinion or letter with respect to compliance
with a condition or covenant provided for in this Indenture (including one
furnished pursuant to specific requirements of this Indenture relating to a
particular application or request) shall include:

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

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

                (3)     a statement that, in the opinion of each such
        individual, he or she has made such examination or investigation as is
        necessary to enable such individual 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 11.02. 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.

                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 other certificate or opinion is based
are erroneous. Any such Issuer 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 Authorized Officer or Officers of the Owner Trustee or a
certificate of the officers of the Depositor or the manager of the Issuer,
stating that the information with respect to such factual matters is in the
possession of the Owner Trustee, or the Depositor or the manager of the Issuer,
unless such officer or counsel knows, or in the exercise of reasonable care
should know, that the certificate or opinion or representations with respect to
such matters are erroneous. Any Opinion of Counsel may be based on the written
opinion of other counsel, in which event such Opinion of Counsel shall be
accompanied by a copy of such other counsel's opinion and shall include a
statement to the effect that such counsel believes that such counsel and the
Trustee may reasonably rely upon the opinion of such other counsel.

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

                Wherever in this Indenture, in connection with any application
or certificate or report to the Trustee, it is


                                      XI-2
<PAGE>   126
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 6.01(b)(2).

                Whenever in this Indenture it is provided that the absence of
the occurrence and continuation of a Default or Event of Default is a condition
precedent to the taking of any action by the 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 6.01(d).

SECTION 11.03. ACTS OF BONDHOLDERS.

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


                                      XI-3
<PAGE>   127
                (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 acknowledgements of deeds, certifying that the individual signing
such instrument or writing acknowledged to him or her 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 or her 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 any
notation of such action is made upon such Bonds.

SECTION 11.04. 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;

                (2)     the Issuer by the Trustee or by any Bondholder shall be
        sufficient for every purpose hereunder (except as provided in Sections
        5.01(3) and (4)) if in writing and mailed, first-class, postage prepaid,
        to the Issuer addressed to it c/o Wilmington Trust Company, as Owner
        Trustee, Rodney Square North, 1100 N. Market Street, Wilmington, DE

SECTION 11.05. NOTICES AND REPORTS TO BONDHOLDERS; WAIVER OF NOTICES.

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

<PAGE>   129
                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.

                Where this Indenture provides for notice to Bondholders of any
event, such notice shall also be sent to S&P, so long as S&P is a Rating Agency
and to Moody's so long as Moody's is a Rating Agency.

SECTION 11.06. 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 11.07. CONFLICT WITH TRUST INDENTURE ACT.

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

                In case any provision in this Indenture or in the Bonds shall be
invalid, illegal or unenforceable, the validity,


                                      XI-6

legality and enforceability of the remaining provisions shall not in any way be
affected or impaired thereby.

SECTION 11.11. BENEFITS OF INDENTURE.

                Except as provided in Section 12.01(i) hereof, 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 and the Bondholders, any benefit or any
legal or equitable right, remedy or claim under this Indenture.

SECTION 11.12. LEGAL HOLIDAYS.

                In any case where the date of any Payment Date, Redemption Date
or any other date on which principal of, or interest on, any Bond is proposed to
be paid shall not be a Business Day, then (notwithstanding any other provision
of the Bonds or this Indenture) payment need not be made on such date, but may
be made on the next succeeding Business Day with the same force and effect as if
made on the nominal date of any such Payment Date, Redemption Date or other date
for the payment of principal of, or interest on, any Bond, 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.

                This Indenture and each Bond shall be construed in accordance
with and governed by the substantive laws of the State of New York applicable to
agreements made and to be performed in the State of New York and the
obligations, rights and remedies of the parties hereto and the Bondholders shall
be determined in accordance with such laws.

SECTION 11.15. RECORDING OF INDENTURE.

                This Indenture is subject to recording in any appropriate public
recording office, 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 Section 3.06.

SECTION 11.16. ISSUER OBLIGATION.

                No recourse may be taken, directly or indirectly, against (i)
the Bank, (ii) any incorporator, subscriber to the capital stock, stockholder,
officer or director of the Bank or of any predecessor or successor of the Bank,
(iii) any holder of a beneficial interest in the Issuer (solely in its capacity
as such), (iv) any incorporator, subscriber to the capital stock, stockholder,
partner, beneficiary, agent, officer, director, employee, or successor or assign
of a holder of a beneficial interest in the Issuer, (v) the Depositor or any
Affiliate thereof (other than the Issuer) or (vi) any incorporator, subscriber
to the capital stock, stockholder, officer, director or employee of the Trustee
or any predecessor or successor of the Trustee with respect to the Issuer's
obligation with respect to the Bonds or the obligation 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.

permit any representative of the Trustee or MBIA, during the Issuer's normal
business hours, to examine all 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 or MBIA, as the
case may be, 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 reasonable expense incident to the exercise
by the Trustee or MBIA of any rights under this Section 11.17 shall be borne by
the Issuer.

SECTION 11.18. USURY.

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

SECTION 11.19. NO PETITION.

                The Trustee, by entering into this Indenture, and each
Bondholder, by accepting a Bond, hereby covenant and agree that they will not at
any time institute against the Depositor or the Issuer, or join in any
institution against the Depositor or the Issuer of, any bankruptcy,
reorganization, arrangement, insolvency or liquidation proceedings, or other
proceedings under any United States federal or state bankruptcy or similar law
in connection with any obligations relating to the Bonds, this Indenture or any
of the Operative Agreements.

                                THE BOND INSURER

SECTION 12.01. CERTAIN MATTERS REGARDING MBIA AND THE MBIA POLICY.

                (a)     Rights of MBIA to Exercise Certain Rights of
Bondholders. By accepting its Bond, each bondholder agrees that unless a MBIA
Default exists, MBIA shall have the right to exercise the Voting Rights of the
Bondholders with respect to all matters, including without limitation the
following matters without any further consent of the Bondholders, to the extent
such rights are provided for herein:

                        (i)     the right to direct the Trustee to terminate the
        rights and obligations of the Master Servicer under the Master Servicing
        Agreement in the event of a default by the Master Servicer;

                        (ii)    the right to consent to or direct any waivers of
        defaults by the Master Servicer;

                        (iii)   the right to remove the Trustee pursuant to this
        Indenture;

                        (iv)    the right to institute proceedings against the
        Master Servicer and the right to direct Proceedings pursuant to Section
        5.14 of this Indenture;

                        (v)     the right to require the Issuer, the Company or
        Redwood to repurchase or substitute Pledged Mortgage Loans pursuant to
        this Indenture;

                        (vi)    the right to accelerate maturity of the Bonds or
        rescind a declaration of acceleration pursuant to Section 5.02 of this
        Indenture;

                        (vii)   the right to direct the exercise of all remedies
        pursuant to Section 5.04 of this Indenture;


                                     XII-1
<PAGE>   134
                        (viii)  the right to request that the Trustee take
        possession of and retain the Trust Estate pursuant to Section 5.05 of
        this Indenture or to rescind such election by the Trustee pursuant to
        the same section; and

                        (ix)    the right to waive any past Default pursuant to
        Section 5.15 of this Indenture.

                In addition, unless a MBIA Default exists, MBIA's consent will
be required prior to, among other things, (i) the appointment of any successor
Trustee, Master Servicer or Servicer or (ii) any amendment to the Indenture;
provided, however, that MBIA shall not unreasonably withhold, condition or delay
its consent. Each Bondholder agrees that, unless a MBIA Default exists, the
rights specifically set forth above may be exercised by the Bondholders only
with the prior written consent of MBIA.

                (b)     Issuer to Act Solely with Consent of MBIA. Unless a MBIA
Default exists and is continuing, the Issuer shall not exercise the right to
appoint a co-trustee pursuant to Section 6.14 of this Indenture or successor
trustee pursuant to Section 6.10 of this Indenture without the prior written
consent of MBIA.

                Unless a MBIA Default exists and is continuing, the Issuer and
the Trustee shall not undertake any litigation with respect to the Trust Estate
without the prior consent and at the direction of MBIA.

                (c)     Trustee to Act Solely with Consent of MBIA. Unless a
MBIA Default exists and is continuing, the Trustee shall not exercise the right
to:

                        (i)     agree to any amendment of this Indenture,
        Deposit Trust Agreement or Master Servicing Agreement pursuant to
        Article IX of this Indenture;

                        (ii)    undertake any litigation pursuant to the
        Indenture or incur any expenses reimbursable pursuant to Section 6.03 of
        this Indenture;

                        (iii)   exercise any of the remedies set forth in
        Section 5.04 or 5.06 of this Indenture;


                                     XII-2
<PAGE>   135
                        (iv)    appoint co-trustees or separate trustees
        pursuant to Section 6.14 of this Indenture; or

                        (v)     agree to any amendment to, or grant any waiver
        of rights under, the Servicing Agreements, or Master Servicing
        Agreement;

without the prior written consent of MBIA, which shall not be unreasonably
withheld; provided, however, during the existence and continuation of a MBIA
Default the Trustee shall not require the prior written consent of MBIA to
exercise any of the rights enumerated above.

                (d)     Trust Estate and Accounts Held for Benefit of MBIA and
the Bondholders. The Trustee shall hold the Trust Estate (subject to the
obligations of each Custodian) for the benefit of the Bondholders and, unless a
MBIA Default exists and is continuing, MBIA, and all references in this
Indenture and in the Bonds to the benefit of Holders of the Bonds shall, unless
a MBIA Default exists and is continuing, be deemed to include MBIA. The Trustee
shall, unless a MBIA Default exists and is continuing, cooperate in all
reasonable respects with any reasonable request by MBIA for action to preserve
or enforce MBIA's rights or interests under this Indenture and the Bonds.

                (e)     Claims Upon the MBIA Policy.

                        (i)     The Trustee shall (A) receive as
        attorney-in-fact of each Bondholder any Insured Payment from MBIA or on
        behalf of MBIA and (B) disburse such Insured Payment to such Bondholders
        in accordance with Section 2.03(b) hereof for the benefit of the related
        Bondholders. Any Insured Payment received by the Trustee shall be held
        by the Trustee uninvested. Insured Payments disbursed by the Trustee
        from proceeds of the MBIA Policy shall not be considered payment by the
        Issuer with respect to the Bonds, nor shall such payments discharge the
        obligation of the Issuer with respect to such Bonds, and MBIA shall
        become the owner of such unpaid amounts due from the Issuer in respect
        of such Insured Payments as the deemed assignee and subrogee of such
        Bondholders and shall be entitled to receive the MBIA Reimbursement
        Amount in respect thereof. The Trustee hereby agrees on behalf of each
        Bondholder for the benefit of MBIA 


                                     XII-3
<PAGE>   136
        that it recognizes that to the extent MBIA makes Insured Payments for
        the benefit of the Bondholders, MBIA will be entitled to receive the
        related MBIA Reimbursement Amount in accordance with the priority of
        distributions referenced in Section 2.03(b) hereof.

                        (ii)    The Trustee shall promptly notify MBIA of any
        proceeding or the institution of any action, of which an Officer of the
        Trustee has actual knowledge, constituting a Preference Claim in respect
        of any payment made on the Bonds. Each Bondholder that pays any amount
        pursuant to a Preference Claim theretofore received by such Bondholder
        on account of a Bond will be entitled to receive reimbursement for such
        amounts from MBIA in accordance with the terms of the MBIA Policy. Each
        Bondholder, by its purchase of Bonds, and the Trustee hereby agree that,
        MBIA (so long as no MBIA Payment Default exists) may at any time during
        the continuation of any proceeding relating to a Preference Claim direct
        all matters relating to such Preference Claim, including, without
        limitation, (i) the direction of any appeal of any order relating to
        such Preference Claim and (ii) the posting of any surety, supersedeas or
        performance bond pending any such appeal. In addition and without
        limitation of the foregoing, MBIA shall be subrogated to the rights of
        the Trustee and each Bondholder in the conduct of any such Preference
        Claim, including, without limitation, all rights of any party to any
        adversary proceeding action with respect to any court order issued in
        connection with any such Preference Claim.

                        (iii)   Each Bondholder, by its purchase of Bonds, and
        the Trustee hereby agree that, unless a MBIA Payment Default exists and
        is continuing, MBIA shall have the right to direct all matters relating
        to the Bonds in any proceeding in a bankruptcy of the Issuer, including
        without limitation any proceeding relating to a Preference Claim, any
        appeal of any order relating to a Preference Claim and the posting of
        any surety or bond pending any such appeal.

                        (iv)    With respect to a Preference Claim, the Trustee
        shall be responsible for procuring and delivering the items set forth in
        Section 3(o) of the Master Servicing Agreement to the Master Servicer.


                                     XII-4
<PAGE>   137
                (f)     Trustee to Cooperate. Unless a MBIA Default exists and
is continuing, the Trustee shall cooperate in all respects with any reasonable
request by MBIA for action to preserve or enforce MBIA's rights or interests
hereunder without limiting the rights or affecting the interests of the
Bondholders as otherwise set forth herein.

                (g)     Surrender and Cancellation. The Trustee shall surrender
the MBIA Policy to MBIA for cancellation upon the expiration of the term of the
MBIA Policy as provided in the MBIA Policy.

                (h)     Reports to MBIA. All notices, statements, reports,
certificates or opinions required by this Indenture to be sent to any other
party hereto or to any of the Bondholders shall also be sent to MBIA. The Issuer
and the Trustee shall make available to MBIA their books and records for the
purpose of copying and inspection of any information about the Bonds or the
Bondholders.

                (i)     Third-Party Beneficiary. MBIA shall be a third- party
beneficiary of this Indenture, entitled to enforce the provisions thereof as if
a party thereto.

                (j)     Costs and Expenses. MBIA shall not be responsible for
any costs or expenses relating to the Trust Estate or the Pledged Mortgages
except for the payment of amounts pursuant to the MBIA Policy.

                (k)     Survival of MBIA's Right to be Reimbursed.
Notwithstanding Section 4.01 of this Indenture, this Indenture shall not be
discharged or satisfied until satisfaction of the conditions set forth therein
and payment of the MBIA Reimbursement Amount. MBIA's right to receive the MBIA
Reimbursement Amount shall survive the satisfaction and discharge of this
Indenture.

                (l)     Opinions of Counsel. While the MBIA Policy is in effect,
each Opinion of Counsel rendered pursuant to the Indenture or the Master
Servicing Agreement, the MLPA, the Deposit Trust Agreement, Custodial Agreements
or Management Agreement also shall be addressed to MBIA.

<PAGE>   145
                This Bond is one of a duly authorized issue of Bonds of the
Issuer, designated as its Collateralized Mortgage Bonds (herein called the
"Bonds"). The Bonds are issuable in one or more classes; the Bonds of particular
Classes being herein called the Class A-1 and Class A-2 Bonds, all issued and to
be issued under the Issuer's Indenture dated as of June 1, 1997 between the
Issuer and First Union National Bank (the "Trustee", which term includes any
successor Trustee under the Indenture), which authorized the Bonds, and
reference is hereby made thereto for a statement of the respective rights
thereunder of the Issuer, the Trustee and the Holders of the Bonds of each
particular Class thereof and the terms upon which the Bonds of each Class are,
and are to be, authenticated and delivered. The Bond is one of the Class A-1
Bonds.

                All terms used in this Bond which are defined in the Indenture
shall have the meanings assigned to them in the Indenture or, if not defined
therein, in the Master Servicing Agreement.

                The interest rate for the Class A-1 Bonds (the "Class A-1
Interest Rate") on each Payment Date after the first Payment Date and up to and
including the Payment Date on which the Issuer is first permitted to exercise
its option to redeem the Bonds will be equal to the lesser of (i) a per annum
floating rate equal to LIBOR (as defined in the Master Servicing Agreement), for
the related Interest Accrual Period plus 0.38% and (ii) 10% per annum. If the
Issuer does not exercise its option to redeem the Bonds on the first Payment
Date on which it is permitted to do so, on the next succeeding Payment Date, the
Class A-1 Interest Rate will increase and for the remaining term of the Bonds
will be equal to the lesser of (i) a per annum floating rate equal to LIBOR for
the related Interest Accrual Period plus 0.76% and (ii) 10.38% per annum. The
Class A-1 Interest Rate for the first Payment Date will equal 6.02844% per
annum.

                As provided in the Indenture, the Bonds are issuable in Classes
which may vary as is provided or permitted in the Indenture. Bonds of each Class
are equally and ratably secured by the collateral pledged as security therefor
to the extent provided by the Indenture.

                For each Payment Date, the aggregate amount of each installment
of interest due and payable on the Class A-1 Bonds will


                                      II-4
<PAGE>   146
be equal to the Class A-1 Interest Payment Amount for such Payment Date.

                The "Class A-1 Interest Payment Amount" means, as of any Payment
Date, the sum of (i) one month's interest at the Class A-1 Interest Rate on the
then outstanding Principal Amount of the Class A-1 Bonds immediately prior to
such Payment Date and (ii) the sum of the amounts, if any, by which the amount
described in clause (i) above on each prior Payment Date exceeded the amount
actually distributed as interest on such Bonds on such prior Payment Dates and
was not subsequently distributed, together with, to the extent permitted by
applicable law, interest on the amount described in clause (ii) at the Class A-1
Interest Rate; provided, that, solely in the case where an MBIA Default shall
have occurred and is continuing, the rate at which the amount in clause (i)
above is calculated shall be the lesser of the Class A-1 Interest Rate and the
Weighted Average Net Mortgage Rate for the related Payment Date (unless such
Payment Date would be the seventh consecutive Payment Date on which at least one
of the Bond Interest Rates would be equal to the Weighted Average Net Mortgage
Rate, in which case, this proviso shall be disregarded for such Payment Date
regardless of any continuation of such MBIA Default). For any Payment Date on
which interest accrues in the Class A-1 Bonds based on the Weighted Average Net
Mortgage Rate, Class A-1 Bondholders' Interest Carryover will accrue which will
be payable as provided in the Master Servicing Agreement and the Indenture.

                For each Payment Date, the aggregate amount of each installment
of principal due and payable on the Class A-1 Bonds will be equal to such
Class's pro rata share of the Principal Payment Amount for such Payment Date.
The Principal Payment Amount shall be as defined in the Master Servicing
Agreement and shall in no event be less for any Payment Date than the excess, if
any, of the aggregate Principal Amount of the Bonds immediately prior to such
Payment Date over the Pool Principal Balance with respect to such Payment Date.
The entire unpaid principal amount of this Bond shall be due and payable, if not
then previously paid, on the Stated Maturity set forth on the face hereof.

                All payments of principal of, and interest on, the Bonds shall
be made only from the Trust Estate Granted as security for the Bonds, the Policy
referred to below and any other assets of the Issuer that have not been Granted
as security for any other bonds


                                      II-5
<PAGE>   147
or obligations of the Issuer, and each Holder hereof, by its acceptance of this
Bond, agrees that it will have recourse solely against such Trust Estate and
such other assets of the Issuer and that neither Wilmington Trust Company in its
individual capacity, any holder of a beneficial interest in the Issuer nor any
of their respective shareholders, partners, beneficiaries, agents, officers,
directors, employees, successors or assigns shall be personally liable for any
amounts payable, or performance due, under this Bond or the Indenture.

                Payment of the then remaining unpaid principal amount of this
Bond on the Stated Maturity of its final installment of principal or on such
earlier date as the Issuer shall be required to pay the then remaining unpaid
principal amount of this Bond or payment of the Redemption Price payable on any
date as of which this Bond has been called for redemption in full, shall be made
upon presentation of this Bond to the office or agency of the Issuer maintained
for such purpose. Payments of interest on this Bond due and payable on each
Payment Date or on any Redemption Date, to the extent this Bond is not being
paid in full, together with any installment of principal of this Bond due and
payable on each Payment Date or the Redemption Date, to the extent not in full
payment of this Bond, shall be made by check mailed to the Person whose name
appears as the registered Holder of this Bond (or one or more Predecessor Bonds)
on the Bond Register as of the last day of the second month preceding the month
in which such Payment Date occurs (each a "Record Date").

                Checks for amounts which include installments of principal due
on this Bond shall be mailed to the Person entitled thereto at the address of
such Person as it appears on the Bond Register as of the applicable Record Date
without requiring that this Bond be submitted for notation of payment and checks
returned undelivered will be held for payment to the Person entitled thereto,
subject to the terms of the Indenture, at the office or agency in the United
States of America designated by the Issuer for such purpose pursuant to the
Indenture. Any reduction in the principal amount of this Bond (or any one or
more Predecessor Bonds) effected by any payments made on any Payment Date shall
be binding upon all Holders of this Bond and of any Bond issued upon the
registration of transfer hereof or in exchange hereof or in lieu hereof, whether
or not noted hereon.


                                      II-6

        If funds are expected to be available, as provided in the Indenture, for
payment in full of the then remaining unpaid principal amount of this Bond on a
Payment Date or Redemption Date which is prior to the Stated Maturity of the
final installment of principal hereof, then the Trustee, on behalf of the
Issuer, will notify the Person who was the registered Holder hereof on the last
day of the month prior to the month in which such Payment Date or Redemption
Date occurs, and the amount then due and payable shall, if sufficient funds
therefor are available, be payable only upon presentation of this Bond to the
office or agency of the Issuer maintained for such purpose.

                The failure of the Issuer to pay when and as due any installment
of principal of (regardless of the lapse of any grace period) any Bond shall not
constitute an Event of Default under the Indenture unless the aggregate
Principal Amount of the Bonds exceeds the Pool Principal Balance with respect to
a Payment Date of the Pledged Mortgages after application of all available
amounts on deposit in the Distribution Account on a Payment Date or unless the
Bonds are not paid in full at their Stated Maturity.

                If an Event of Default as defined in the Indenture shall occur
and be continuing with respect to the Bonds, the Bonds may become or be declared
due and payable in the manner and with the effect provided in the Indenture. If
any such acceleration of maturity occurs prior to the Stated Maturity of the
final installment of principal of this Bond, the amount payable to the Holder of
this Bond will be equal to the Principal Amount of this Bond on the date this
Bond becomes so due and payable, together with accrued interest. Following the
acceleration of the maturity of the Bonds, all amounts collected as proceeds of
the collateral securing the Bonds or otherwise shall be applied as described in
the Indenture. Following such acceleration, interest on any overdue installments
of interest on all Bonds shall be payable at the rate set forth in the
Indenture.

                The Bonds are not prepayable or redeemable at the option or
direction of the Issuer except that the Bonds are subject to redemption in
whole, but not in part, at the option of the Issuer on any Payment Date after
the earlier of (a) seven years after the initial issuance of the Bonds and (b)
the Payment Date after which the Pool Principal Balance with respect to such
Payment Date, is 35% or less of the Original Pool Principal Balance, at a
redemption


                                      II-7
<PAGE>   149
price equal to 100% of the unpaid Principal Balance for each such Class of
Bonds, plus accrued and unpaid interest thereon at the Class A-1 Bond Interest
Rate. The Bonds are also subject to redemption by the Issuer upon the exercise
by the Master Servicer or the Insurer of its right to purchase the remaining
outstanding Pledged Mortgages which right may be exercised, upon the giving of
required notice to the Issuer, on any Payment Date after the Payment Date with
respect to which the Pool Principal Balance is equal to 10% or less of the
Original Pool Principal Balance. Any redemption of the Bond shall be at a price
equal to 100% of the unpaid principal amount of this Bond plus accrued and
unpaid interest hereon to the date of interest redemption.

                As provided in the Indenture and subject to certain limitations
therein set forth, the transfer of this Bond may be registered on the Bond
Register of the Issuer, upon surrender of this Bond for registration of transfer
at the office or agency designated by the Issuer pursuant to the Indenture, duly
endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Trustee duly executed by the Holder hereof or his attorney
duly authorized in writing, and thereupon one or more new Bonds of the same
Class, of authorized denominations and in the same aggregate initial principal
amount, will be issued to the designated transferee or transferees.

                Prior to the due presentment for registration of transfer of
this Bond, the Issuer, the Trustee, and any agent of the Issuer shall treat the
Person in whose name this Bond is registered (i) on any Record Date, for
purposes of making payments, and (ii) on any other date for any other purposes,
as the owner hereof, whether or not this Bond be overdue, and neither the
Issuer, the Trustee nor any such agent shall be affected by notice to the
contrary.

                The Indenture permits, subject to the rights of the Insurer and
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 Balance Amount of
the Bonds. The Indenture also contains provisions permitting the Holders of
Bonds representing specified percentages of the aggregate Principal Amount of
the Bonds on behalf of the Holders of all the Bonds, subject to the rights of
the Insurer, to


                                      II-8
<PAGE>   150
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 herefor 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 Trustee, subject to the rights of the Insurer, 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 and also
permits certain amendments without the consent of Bondholders.

                As provided in the Indenture, the Insurer shall have the right
to control the exercise of certain remedies set forth therein and to exercise
certain of the voting rights of the Holders of the Bonds and certain other
rights may only be exercised with the consent of the Insurer.

                The Bonds are "Book Entry Bonds" which will be available to
investors only through the book entry facilities of The Depository Trust
Company, and bond certificates for all Classes of Bonds will be available only
under certain limited circumstances as described in the Indenture.

                AS PROVIDED IN THE INDENTURE, THIS BOND AND THE INDENTURE SHALL
BE CONSTRUED IN ACCORDANCE WITH, AND GOVERNED BY, THE LAWS OF THE STATE OF NEW
YORK APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED THEREIN.

                No reference herein to the Indenture and no provision of this
Bond or of the Indenture shall alter or impair the obligation of the Issuer,
which is absolute and unconditional to the extent permitted by applicable law,
to pay the principal of, and interest on, this Bond at the times, place and
rate, and in the coin or currency herein prescribed.

                MBIA Insurance Corporation (the "Insurer"), has issued a
Financial Guaranty Insurance Policy (the "Policy") relating to the Obligations
containing the following provisions, the Policy being on file at the Corporate
Trust Office of the Trustee.

                The Insurer, in consideration of the payment of the premium and
subject to the terms of the Policy, hereby unconditionally and irrevocably
guarantees to any Owner (as defined below) that an amount equal to each full and
complete Insured Payment will be received by First Union National Bank,
Charlotte, NC, or its successor, as trustee for the Owners (the "Trustee"), on
behalf of the Owners from the Insurer, for distribution by the Trustee to each
Owner of each Owner's proportionate share of the Insured Payment. The Insurer's
obligations under the Policy with respect to a particular Insured Payment shall
be discharged to the extent funds equal to the applicable Insured Payment are
received by the Trustee, whether or not such funds are properly applied by the
Trustee. Insured Payments shall be made only at the time set forth in the Policy
and no accelerated Insured Payments shall be made regardless of any acceleration
of the Obligations, unless such acceleration is at the sole option of the
Insurer.

                Notwithstanding the foregoing paragraph, the Policy does not
cover shortfalls, if any, attributable to the liability of the Issuer or the
Trustee for withholding taxes, if any (including interest and penalties in
respect of any such liability).

                The Insurer will pay any Insured Payment that is a Preference
Amount on the Business Day following receipt on a Business Day by the Fiscal
Agent (as described below) of (i) a certified copy of the order requiring the
return of a preference payment, (ii) an opinion of counsel satisfactory to the
Insurer that such order is final and not subject to appeal, (iii) an assignment
in such form as is reasonably required by the Insurer, irrevocably assigning to
the Insurer all rights and claims of the Owner relating to or arising under the
Obligations against the debtor which made such preference payment or otherwise
with respect to such preference payment and (iv) appropriate instruments to
effect the appointment of the Insurer as agent for such Owner in any legal
proceeding related to such preference payment, such instruments being in a


                                     II-10
<PAGE>   152
form satisfactory to the Insurer, provided that if such documents are received
after 12:00 noon New York City time on such Business Day, they will be deemed to
be received on the following Business Day. Such payments shall be disbursed to
the receiver or trustee in bankruptcy named in the final order of the court
exercising jurisdiction on behalf of the Owner and not to any Owner directly
unless such Owner has returned principal or interest paid on the Obligations to
such receiver or trustee in bankruptcy, in which case payment shall be disbursed
to such Owner.

<PAGE>   153
                The Insurer will pay any other amount payable hereunder no later
than 12:00 noon New York City time on the later of the Payment Date on which the
related Deficiency Amount is due or the second Business Day following receipt in
New York, New York on a Business Day by State Street Bank and Trust Company,
N.A., as Fiscal Agent for the Insurer or any successor fiscal agent appointed by
the Insurer (the "Fiscal Agent") of a Notice (as described below); provided that
if such Notice is received after 12:00 noon New York City time on such Business
Day, it will be deemed to be received on the following Business Day. If any such
Notice received by the Fiscal Agent is not in proper form or is otherwise
insufficient for the purpose of making claim under the Policy, it shall be
deemed not to have been received by the Fiscal Agent for purposes of this
paragraph, and the Insurer or the Fiscal Agent, as the case may be, shall
promptly so advise the Trustee and the Trustee may submit an amended Notice.

                Insured Payments due under the Policy, unless otherwise stated
in the Policy, will be disbursed by the Fiscal Agent to the Trustee on behalf of
the Owners by wire transfer of immediately available funds in the amount of the
Insured Payment less, in respect of Insured Payments related to Preference
Amounts, any amount held by the Trustee for the payment of such Insured Payment
and legally available therefor.

                The Fiscal Agent is the agent of the Insurer only and the Fiscal
Agent shall in no event be liable to Owners for any acts of the Fiscal Agent or
any failure of the Insurer to deposit, or cause to be deposited, sufficient
funds to make payments due under this Policy.

                Subject to the terms of the Indenture, the Insurer shall be
subrogated to the rights of each Owner to receive payments under the Obligations
to the extent of any payment by the Insurer under the Policy.

                As used in the Policy, the following terms shall have the

<PAGE>   161
                This Bond is one of a duly authorized issue of Bonds of the
Issuer, designated as its Collateralized Mortgage Bonds (herein called the
"Bonds"). The Bonds are issuable in one or more classes; the Bonds of particular
Classes being herein called the Class A-1 and Class A-2 Bonds, all issued and to
be issued under the Issuer's Indenture dated as of June 1, 1997 between the
Issuer and First Union National Bank (the "Trustee", which term includes any
successor Trustee under the Indenture), which authorized the Bonds, and
reference is hereby made thereto for a statement of the respective rights
thereunder of the Issuer, the Trustee and the Holders of the Bonds of each
particular Class thereof and the terms upon which the Bonds of each Class are,
and are to be, authenticated and delivered. The Bond is one of the Class A-1
Bonds.

                All terms used in this Bond which are defined in the Indenture
shall have the meanings assigned to them in the Indenture or, if not defined
therein, in the Master Servicing Agreement.

                The interest rate for the Class A-1 Bonds (the "Class A-1
Interest Rate") on each Payment Date after the first Payment Date and up to and
including the Payment Date on which the Issuer is first permitted to exercise
its option to redeem the Bonds will be equal to the lesser of (i) a per annum
floating rate equal to LIBOR (as defined in the Master Servicing Agreement), for
the related Interest Accrual Period plus 0.38% and (ii) 10% per annum. If the
Issuer does not exercise its option to redeem the Bonds on the first Payment
Date on which it is permitted to do so, on the next succeeding Payment Date, the
Class A-1 Interest Rate will increase and for the remaining term of the Bonds
will be equal to the lesser of (i) a per annum floating rate equal to LIBOR for
the related Interest Accrual Period plus 0.76% and (ii) 10.38% per annum. The
Class A-1 Interest Rate for the first Payment Date will equal 6.02844% per
annum.

                As provided in the Indenture, the Bonds are issuable in Classes
which may vary as is provided or permitted in the Indenture. Bonds of each Class
are equally and ratably secured by the collateral pledged as security therefor
to the extent provided by the Indenture.

                For each Payment Date, the aggregate amount of each installment
of interest due and payable on the Class A-1 Bonds will


                                     II-20
<PAGE>   162
be equal to the Class A-1 Interest Payment Amount for such Payment Date.

                The "Class A-1 Interest Payment Amount" means, as of any Payment
Date, the sum of (i) one month's interest at the Class A-1 Interest Rate on the
then outstanding Principal Amount of the Class A-1 Bonds immediately prior to
such Payment Date and (ii) the sum of the amounts, if any, by which the amount
described in clause (i) above on each prior Payment Date exceeded the amount
actually distributed as interest on such Bonds on such prior Payment Dates and
was not subsequently distributed, together with, to the extent permitted by
applicable law, interest on the amount described in clause (ii) at the Class A-1
Interest Rate; provided, that, solely in the case where an MBIA Default shall
have occurred and is continuing, the rate at which the amount in clause (i)
above is calculated shall be the lesser of the Class A-1 Interest Rate and the
Weighted Average Net Mortgage Rate for the related Payment Date (unless such
Payment Date would be the seventh consecutive Payment Date on which at least one
of the Bond Interest Rates would be equal to the Weighted Average Net Mortgage
Rate, in which case, this proviso shall be disregarded for such Payment Date
regardless of any continuation of such MBIA Default). For any Payment Date on
which interest accrues in the Class A-1 Bonds based on the Weighted Average Net
Mortgage Rate, Class A-1 Bondholders' Interest Carryover will accrue which will
be payable as provided in the Master Servicing Agreement and the Indenture.

                For each Payment Date, the aggregate amount of each installment
of principal due and payable on the Class A-1 Bonds will be equal to such
Class's pro rata share of the Principal Payment Amount for such Payment Date.
The Principal Payment Amount shall be as defined in the Master Servicing
Agreement and shall in no event be less for any Payment Date than the excess, if
any, of the aggregate Principal Amount of the Bonds immediately prior to such
Payment Date over the Pool Principal Balance with respect to such Payment Date.
The entire unpaid principal amount of this Bond shall be due and payable, if not
then previously paid, on the Stated Maturity set forth on the face hereof.

               All payments of principal of, and interest on, the Bonds shall be
made only from the Trust Estate Granted as security for the Bonds, the Policy
referred to below and any other assets of the Issuer that have not been Granted
as security for any other bonds  


                                     II-21
<PAGE>   163
or obligations of the Issuer, and each Holder hereof, by its acceptance of this
Bond, agrees that it will have recourse solely against such Trust Estate and
such other assets of the Issuer and that neither Wilmington Trust Company in its
individual capacity, any holder of a beneficial interest in the Issuer nor any
of their respective shareholders, partners, beneficiaries, agents, officers,
directors, employees, successors or assigns shall be personally liable for any
amounts payable, or performance due, under this Bond or the Indenture.

                Payment of the then remaining unpaid principal amount of this
Bond on the Stated Maturity of its final installment of principal or on such
earlier date as the Issuer shall be required to pay the then remaining unpaid
principal amount of this Bond or payment of the Redemption Price payable on any
date as of which this Bond has been called for redemption in full, shall be made
upon presentation of this Bond to the office or agency of the Issuer maintained
for such purpose. Payments of interest on this Bond due and payable on each
Payment Date or on any Redemption Date, to the extent this Bond is not being
paid in full, together with any installment of principal of this Bond due and
payable on each Payment Date or the Redemption Date, to the extent not in full
payment of this Bond, shall be made by check mailed to the Person whose name
appears as the registered Holder of this Bond (or one or more Predecessor Bonds)
on the Bond Register as of the last day of the second month preceding the month
in which such Payment Date occurs (each a "Record Date").

                Checks for amounts which include installments of principal due
on this Bond shall be mailed to the Person entitled thereto at the address of
such Person as it appears on the Bond Register as of the applicable Record Date
without requiring that this Bond be submitted for notation of payment and checks
returned undelivered will be held for payment to the Person entitled thereto,
subject to the terms of the Indenture, at the office or agency in the United
States of America designated by the Issuer for such purpose pursuant to the
Indenture. Any reduction in the principal amount of this Bond (or any one or
more Predecessor Bonds) effected by any payments made on any Payment Date shall
be binding upon all Holders of this Bond and of any Bond issued upon the
registration of transfer hereof or in exchange hereof or in lieu hereof, whether
or not noted hereon.


                                     II-22
<PAGE>   164
        If funds are expected to be available, as provided in the Indenture, for
payment in full of the then remaining unpaid principal amount of this Bond on a
Payment Date or Redemption Date which is prior to the Stated Maturity of the
final installment of principal hereof, then the Trustee, on behalf of the
Issuer, will notify the Person who was the registered Holder hereof on the last
day of the month prior to the month in which such Payment Date or Redemption
Date occurs, and the amount then due and payable shall, if sufficient funds
therefor are available, be payable only upon presentation of this Bond to the
office or agency of the Issuer maintained for such purpose.

                The failure of the Issuer to pay when and as due any installment
of principal of (regardless of the lapse of any grace period) any Bond shall not
constitute an Event of Default under the Indenture unless the aggregate
Principal Amount of the Bonds exceeds the Pool Principal Balance with respect to
a Payment Date of the Pledged Mortgages after application of all available
amounts on deposit in the Distribution Account on a Payment Date or unless the
Bonds are not paid in full at their Stated Maturity.

                If an Event of Default as defined in the Indenture shall occur
and be continuing with respect to the Bonds, the Bonds may become or be declared
due and payable in the manner and with the effect provided in the Indenture. If
any such acceleration of maturity occurs prior to the Stated Maturity of the
final installment of principal of this Bond, the amount payable to the Holder of
this Bond will be equal to the Principal Amount of this Bond on the date this
Bond becomes so due and payable, together with accrued interest. Following the
acceleration of the maturity of the Bonds, all amounts collected as proceeds of
the collateral securing the Bonds or otherwise shall be applied as described in
the Indenture. Following such acceleration, interest on any overdue installments
of interest on all Bonds shall be payable at the rate set forth in the
Indenture.

                The Bonds are not prepayable or redeemable at the option or
direction of the Issuer except that the Bonds are subject to redemption in
whole, but not in part, at the option of the Issuer on any Payment Date after
the earlier of (a) seven years after the initial issuance of the Bonds and (b)
the Payment Date after which the Pool Principal Balance with respect to such
Payment Date, is 35% or less of the Original Pool Principal Balance, at a
redemption


                                     II-23
<PAGE>   165
price equal to 100% of the unpaid Principal Balance for each such Class of
Bonds, plus accrued and unpaid interest thereon at the Class A-1 Bond Interest
Rate. The Bonds are also subject to redemption by the Issuer upon the exercise
by the Master Servicer or the Insurer of its right to purchase the remaining
outstanding Pledged Mortgages which right may be exercised, upon the giving of
required notice to the Issuer, on any Payment Date after the Payment Date with
respect to which the Pool Principal Balance is equal to 10% or less of the
Original Pool Principal Balance. Any redemption of the Bond shall be at a price
equal to 100% of the unpaid principal amount of this Bond plus accrued and
unpaid interest hereon to the date of interest redemption.

                As provided in the Indenture and subject to certain limitations
therein set forth, the transfer of this Bond may be registered on the Bond
Register of the Issuer, upon surrender of this Bond for registration of transfer
at the office or agency designated by the Issuer pursuant to the Indenture, duly
endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Trustee duly executed by the Holder hereof or his attorney
duly authorized in writing, and thereupon one or more new Bonds of the same
Class, of authorized denominations and in the same aggregate initial principal
amount, will be issued to the designated transferee or transferees.

                Prior to the due presentment for registration of transfer of
this Bond, the Issuer, the Trustee, and any agent of the Issuer shall treat the
Person in whose name this Bond is registered (i) on any Record Date, for
purposes of making payments, and (ii) on any other date for any other purposes,
as the owner hereof, whether or not this Bond be overdue, and neither the
Issuer, the Trustee nor any such agent shall be affected by notice to the
contrary.

                The Indenture permits, subject to the rights of the Insurer and
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 Balance Amount of
the Bonds. The Indenture also contains provisions permitting the Holders of
Bonds representing specified percentages of the aggregate Principal Amount of
the Bonds on behalf of the Holders of all the Bonds, subject to the rights of
the Insurer, to


                                     II-24
<PAGE>   166
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 herefor 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 Trustee, subject to the rights of the Insurer, 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 and also
permits certain amendments without the consent of Bondholders.

                As provided in the Indenture, the Insurer shall have the right
to control the exercise of certain remedies set forth therein and to exercise
certain of the voting rights of the Holders of the Bonds and certain other
rights may only be exercised with the consent of the Insurer.

                The Bonds are "Book Entry Bonds" which will be available to
investors only through the book entry facilities of The Depository Trust
Company, and bond certificates for all Classes of Bonds will be available only
under certain limited circumstances as described in the Indenture.

                AS PROVIDED IN THE INDENTURE, THIS BOND AND THE INDENTURE SHALL
BE CONSTRUED IN ACCORDANCE WITH, AND GOVERNED BY, THE LAWS OF THE STATE OF NEW
YORK APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED THEREIN.

                No reference herein to the Indenture and no provision of this
Bond or of the Indenture shall alter or impair the obligation of the Issuer,
which is absolute and unconditional to the extent permitted by applicable law,
to pay the principal of, and interest on, this Bond at the times, place and
rate, and in the coin or currency herein prescribed.

                MBIA Insurance Corporation (the "Insurer"), has issued a
Financial Guaranty Insurance Policy (the "Policy") relating to the Obligations
containing the following provisions, the Policy being on file at the Corporate
Trust Office of the Trustee.

                The Insurer, in consideration of the payment of the premium and
subject to the terms of the Policy, hereby unconditionally and irrevocably
guarantees to any Owner (as defined below) that an amount equal to each full and
complete Insured Payment will be received by First Union National Bank,
Charlotte, NC, or its successor, as trustee for the Owners (the "Trustee"), on
behalf of the Owners from the Insurer, for distribution by the Trustee to each
Owner of each Owner's proportionate share of the Insured Payment. The Insurer's
obligations under the Policy with respect to a particular Insured Payment shall
be discharged to the extent funds equal to the applicable Insured Payment are
received by the Trustee, whether or not such funds are properly applied by the
Trustee. Insured Payments shall be made only at the time set forth in the Policy
and no accelerated Insured Payments shall be made regardless of any acceleration
of the Obligations, unless such acceleration is at the sole option of the
Insurer.

                Notwithstanding the foregoing paragraph, the Policy does not
cover shortfalls, if any, attributable to the liability of the Issuer or the
Trustee for withholding taxes, if any (including interest and penalties in
respect of any such liability).

                The Insurer will pay any Insured Payment that is a Preference
Amount on the Business Day following receipt on a Business Day by the Fiscal
Agent (as described below) of (i) a certified copy of the order requiring the
return of a preference payment, (ii) an opinion of counsel satisfactory to the
Insurer that such order is final and not subject to appeal, (iii) an assignment
in such form as is reasonably required by the Insurer, irrevocably assigning to
the Insurer all rights and claims of the Owner relating to or arising under the
Obligations against the debtor which made such preference payment or otherwise

<PAGE>   176
                This Bond is one of a duly authorized issue of Bonds of the
Issuer, designated as its Collateralized Mortgage Bonds (herein called the
"Bonds"). The Bonds are issuable in one or more classes; the Bonds of particular
Classes being herein called the Class A-1 and Class A-2 Bonds, all issued and to
be issued under the Issuer's Indenture dated as of June 1, 1997 between the
Issuer and First Union National Bank (the "Trustee", which term includes any
successor Trustee under the Indenture), which authorized the Bonds, and
reference is hereby made thereto for a statement of the respective rights
thereunder of the Issuer, the Trustee and the Holders of the Bonds of each
particular Class thereof and the terms upon which the Bonds of each Class are,
and are to be, authenticated and delivered. The Bond is one of the Class A-2
Bonds.

                All terms used in this Bond which are defined in the Indenture
shall have the meanings assigned to them in the Indenture or, if not defined
therein, in the Master Servicing Agreement.

                The interest rate for the Class A-2 Bonds (the "Class A-2
Interest Rate") on each Payment Date after the first Payment Date and up to and
including the Payment Date on which the Issuer is permitted to exercise its
option to redeem the Bonds will be equal to the lesser of (i) a per annum
floating rate equal to the Fed Funds Average Rate (as defined in the Master
Servicing Agreement), for the related Interest Accrual Period plus, 0.54% and
(ii) 10% per annum. If the Issuer does not exercise its option to redeem the
Bonds on the first Payment Date on which it is permitted to do so, on the next
succeeding payment date, the Class A-2 Interest Rate will increase and for the
remaining term of the Bonds will be equal to the lesser of (i) a per annum
floating rate equal to the Fed Funds Average Rate for the related Interest
Accrual Period plus 0.92% and (ii) 10.38% per annum. The Class A-2 Interest Rate
for the first Payment Date will equal 6.04% per annum.

                As provided in the Indenture, the Bonds are issuable in Classes
which may vary as is provided or permitted in the Indenture. Bonds of each Class
are equally and ratably secured by the collateral pledged as security therefor
to the extent provided by the Indenture.

                For each Payment Date, the aggregate amount of each installment
of interest due and payable on the Class A-2 Bonds will


                                     III-4
<PAGE>   177
be equal to the Class A-2 Interest Payment Amount for such Payment Date.

                The "Class A-2 Interest Payment Amount" means, as of any Payment
Date, the sum of (i) one month's interest at the Class A-2 Interest Rate on the
then outstanding Principal Amount of the Class A-2 Bonds immediately prior to
such Payment Date and (ii) the sum of the amounts, if any, by which the amount
described in clause (i) above on each prior Payment Date exceeded the amount
actually distributed as interest on such Bonds on such prior Payment Dates and
was not subsequently distributed, together with, to the extent permitted by
applicable law, interest on the amount described in clause (ii) at the Class A-2
Interest Rate; provided, that, solely in the case where an MBIA Default shall
have occurred and is continuing, the rate at which the amount in clause (i)
above is calculated shall be the lesser of the Class A-2 Interest Rate and the
Weighted Average Net Mortgage Rate for the related Payment Date (unless such
Payment Date would be the seventh consecutive Payment Date on which at least one
of the Bond Interest Rates would be equal to the Weighted Average Net Mortgage
Rate, in which case, this proviso shall be disregarded for such Payment Date
regardless of any continuation of such MBIA Default). For any Payment Date in
which interest accrues in the Class A-2 Bonds based on the Weighted Average Net
Mortgage Rate, Class A-2 Bondholders' Interest Carryover will accrue which will
be payable as provided in the Master Servicing Agreement and the Indenture.

                For each Payment Date, the aggregate amount of each installment
of principal due and payable on the Class A-2 Bonds will be equal to such
Class's pro rata share of the Principal Payment Amount for such Payment Date.
The Principal Payment Amount shall be as defined in the Master Servicing
Agreement and shall in no event be less for any Payment Date than the excess, if
any, of the aggregate Principal Amount of the Bonds immediately prior to such
Payment Date over the Pool Principal Balance with respect to such Payment Date.
The entire unpaid principal amount of this Bond shall be due and payable, if not
then previously paid, on the Stated Maturity set forth on the face hereof.

                All payments of principal of, and interest on, the Bonds shall
be made only from the Trust Estate Granted as security for the Bonds, the Policy
referred to below and any other assets of the Issuer that have not been Granted
as security for any other bonds


                                     III-5
<PAGE>   178
or obligations of the Issuer, and each Holder hereof, by its acceptance of this
Bond, agrees that it will have recourse solely against such Trust Estate and
such other assets of the Issuer and that neither Wilmington Trust Company in its
individual capacity, any holder of a beneficial interest in the Issuer nor any
of their respective shareholders, partners, beneficiaries, agents, officers,
directors, employees, successors or assigns shall be personally liable for any
amounts payable, or performance due, under this Bond or the Indenture.

                Payment of the then remaining unpaid principal amount of this
Bond on the Stated Maturity of its final installment of principal or on such
earlier date as the Issuer shall be required to pay the then remaining unpaid
principal amount of this Bond or payment of the Redemption Price payable on any
date as of which this Bond has been called for redemption in full, shall be made
upon presentation of this Bond to the office or agency of the Issuer maintained
for such purpose. Payments of interest on this Bond due and payable on each
Payment Date or on any Redemption Date, to the extent this Bond is not being
paid in full, together with any installment of principal of this Bond due and
payable on each Payment Date or the Redemption Date, to the extent not in full
payment of this Bond, shall be made by check mailed to the Person whose name
appears as the registered Holder of this Bond (or one or more Predecessor Bonds)
on the Bond Register as of the last day of the second month preceding the month
in which such Payment Date occurs (each a "Record Date").

                Checks for amounts which include installments of principal due
on this Bond shall be mailed to the Person entitled thereto at the address of
such Person as it appears on the Bond Register as of the applicable Record Date
without requiring that this Bond be submitted for notation of payment and checks
returned undelivered will be held for payment to the Person entitled thereto,
subject to the terms of the Indenture, at the office or agency in the United
States of America designated by the Issuer for such purpose pursuant to the
Indenture. Any reduction in the principal amount of this Bond (or any one or
more Predecessor Bonds) effected by any payments made on any Payment Date shall
be binding upon all 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 noted hereon.


                                     III-6
<PAGE>   179
                If funds are expected to be available, as provided in the
Indenture, for payment in full of the then remaining unpaid principal amount of
this Bond on a Payment Date or Redemption Date which is prior to the Stated
Maturity of the final installment of principal hereof, then the Trustee, on
behalf of the Issuer, will notify the Person who was the registered Holder
hereof on the last day of the month prior to the month in which such Payment
Date or Redemption Date occurs, and the amount then due and payable shall, if
sufficient funds therefor are available, be payable only upon presentation of
this Bond to the office or agency of the Issuer maintained for such purpose.

                The failure of the Issuer to pay when and as due any installment
of principal of (regardless of the lapse of any grace period) any Bond shall not
constitute an Event of Default under the Indenture unless the aggregate
Principal Amount of the Bonds exceeds the Pool Principal Balance with respect to
a Payment Date of the Pledged Mortgages after application of all available
amounts on deposit in the Distribution Account on such Payment Date or unless
the Bonds are not paid in full at their Stated Maturity.

                If an Event of Default as defined in the Indenture shall occur
and be continuing with respect to the Bonds, the Bonds may become or be declared
due and payable in the manner and with the effect provided in the Indenture. If
any such acceleration of maturity occurs prior to the Stated Maturity of the
final installment of principal of this Bond, the amount payable to the Holder of
this Bond will be equal to the Principal Amount of this Bond on the date this
Bond becomes so due and payable, together with accrued interest. Following the
acceleration of the maturity of the Bonds, all amounts collected as proceeds of
the collateral securing the Bonds or otherwise shall be applied as described in
the Indenture. Following such acceleration, interest on any overdue installments
of interest on all Bonds shall be payable at the rate set forth in the
Indenture.

                The Bonds are not prepayable or redeemable at the option or
direction of the Issuer except that the Bonds are subject to redemption in
whole, but not in part, at the option of the Issuer on any Payment Date after
the earlier of (a) seven years after the initial issuance of the Bonds and (b)
the Payment Date after which the Pool Principal Balance with respect to such
Payment Date is 35% or less of the Original Pool Principal Balance, at a
redemption


                                     III-7
<PAGE>   180
price equal to 100% of the unpaid Principal Amount for each such Class of Bonds,
plus accrued and unpaid interest thereon at the Class A-2 Bond Interest Rate.
The Bonds are also subject to redemption by the Issuer upon the exercise by the
Master Servicer or the Insurer of its right to purchase the remaining
outstanding Pledged Mortgages which right may be exercised, upon the giving of
required notice to the Issuer, on any Payment Date after the Payment Date with
respect to which the Pool Principal Balance is equal to 10% or less of the
Original Pool Principal Balance. Any redemption of this Bond shall be at a price
equal to 100% of the unpaid principal amount of this Bond plus accrued and
unpaid interest hereon to the date of such redemption.

                As provided in the Indenture and subject to certain limitations
therein set forth, the transfer of this Bond may be registered on the Bond
Register of the Issuer, upon surrender of this Bond for registration of transfer
at the office or agency designated by the Issuer pursuant to the Indenture, duly
endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Trustee duly executed by the Holder hereof or his attorney
duly authorized in writing, and thereupon one or more new Bonds of the same
Class, of authorized denominations and in the same aggregate initial principal
amount, will be issued to the designated transferee or transferees.

                Prior to the due presentment for registration of transfer of
this Bond, the Issuer, the Trustee, and any agent of the Issuer shall treat the
Person in whose name this Bond is registered (i) on any Record Date, for
purposes of making payments, and (ii) on any other date for any other purposes,
as the owner hereof, whether or not this Bond be overdue, and neither the
Issuer, the Trustee nor any such agent shall be affected by notice to the
contrary.

                The Indenture permits, subject to the rights of MBIA and 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 Balance Amount of
the Bonds. The Indenture also contains provisions permitting the Holders of
Bonds representing specified percentages of the aggregate Principal Amount of
the Bonds on behalf of the Holders of all the Bonds, subject to the rights of
MBIA, to waive compliance by the Issuer


                                     III-8
<PAGE>   181
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
Trustee, subject to the rights of MBIA, 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 and also permits certain amendments
without the consent of Bondholders.

                As provided in the Indenture, the Insurer shall have the right
to control the exercise of certain remedies set forth therein and to exercise
certain of the voting rights of the Holders of the Bonds and certain other
rights may only be exercised with the consent of the Insurer.

                The Bonds are "Book Entry Bonds" which will be available to
investors only through the book entry facilities of The Depository Trust
Company, and bond certificates for all Classes of Bonds will be available only
under certain limited circumstances as described in the Indenture.

                AS PROVIDED IN THE INDENTURE, THIS BOND AND THE INDENTURE SHALL
BE CONSTRUED IN ACCORDANCE WITH, AND GOVERNED BY, THE LAWS OF THE STATE OF NEW
YORK APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED THEREIN.

                No reference herein to the Indenture and no provision of this
Bond or of the Indenture shall alter or impair the obligation of the Issuer,
which is absolute and unconditional to the extent permitted by applicable law,

                             Collateralized Mortgage Bonds
                             Class A-1 and Class A-2 Bonds

                MBIA Insurance Corporation (the "Insurer"), has issued a
Financial Guaranty Insurance Policy (the "Policy") relating to the Obligations
containing the following provisions, the Policy being on file at the Corporate
Trust Office of the Trustee.

                The Insurer, in consideration of the payment of the premium and
subject to the terms of the Policy, hereby unconditionally and irrevocably
guarantees to any Owner (as defined below) that an amount equal to each full and
complete Insured Payment will be received by First Union National Bank,
Charlotte, NC, or its successor, as trustee for the Owners (the "Trustee"), on
behalf of the Owners from the Insurer, for distribution by the Trustee to each
Owner of each Owner's proportionate share of the Insured Payment. The Insurer's
obligations under the Policy with respect to a particular Insured Payment shall
be discharged to the extent funds equal to the applicable Insured Payment are
received by the Trustee, whether or not such funds are properly applied by the
Trustee. Insured Payments shall be made only at the time set forth in the Policy
and no accelerated Insured Payments shall be made regardless of any acceleration
of the Obligations, unless such acceleration is at the sole option of the
Insurer.

                Notwithstanding the foregoing paragraph, the Policy does not
cover shortfalls, if any, attributable to the liability of the Issuer or the
Trustee for withholding taxes, if any (including interest and penalties in
respect of any such liability).

                The Insurer will pay any Insured Payment that is a Preference
Amount on the Business Day following receipt on a Business Day by the Fiscal
Agent (as described below) of (i) a certified copy of the order requiring the
return of a preference payment, (ii) an opinion of counsel satisfactory to the
Insurer that such order is final and not subject to appeal, (iii) an assignment
in such form as is reasonably required by the Insurer, irrevocably assigning to
the Insurer all rights and claims of the Owner relating to or arising under the
Obligations against the debtor which made such preference payment or otherwise
with respect to such preference payment and (iv) appropriate instruments to
effect the appointment of the Insurer as agent for such Owner in any legal
proceeding related to such preference payment, such instruments being in a


                                     III-10
<PAGE>   183
form satisfactory to the Insurer, provided that if such documents are received
after 12:00 noon New York City time on such Business Day, they will be deemed to
be received on the following Business Day. Such payments shall be disbursed to
the receiver or trustee in bankruptcy named in the final order of the court
exercising jurisdiction on behalf of the Owner and not to any Owner directly
unless such Owner has returned principal or interest paid on the Obligations to
such receiver or trustee in bankruptcy, in which case payment shall be disbursed
to such Owner.


                                     III-11
<PAGE>   184
                The Insurer will pay any other amount payable hereunder no later
than 12:00 noon New York City time on the later of the Payment Date on which the
related Deficiency Amount is due or the second Business Day following receipt in
New York, New York on a Business Day by State Street Bank and Trust Company,
N.A., as Fiscal Agent for the Insurer or any successor fiscal agent appointed by
the Insurer (the "Fiscal Agent") of a Notice (as described below); provided that
if such Notice is received after 12:00 noon New York City time on such Business
Day, it will be deemed to be received on the following Business Day. If any such
Notice received by the Fiscal Agent is not in proper form or is otherwise
insufficient for the purpose of making claim under the Policy, it shall be
deemed not to have been received by the Fiscal Agent for purposes of this
paragraph, and the Insurer or the Fiscal Agent, as the case may be, shall
promptly so advise the Trustee and the Trustee may submit an amended Notice.

                Insured Payments due under the Policy, unless otherwise stated
in the Policy, will be disbursed by the Fiscal Agent to the Trustee on behalf of
the Owners by wire transfer of immediately available funds in the amount of the
Insured Payment less, in respect of Insured Payments related to Preference
Amounts, any amount held by the Trustee for the payment of such Insured Payment
and legally available therefor.

                The Fiscal Agent is the agent of the Insurer only and the Fiscal
Agent shall in no event be liable to Owners for any acts of the Fiscal Agent or
any failure of the Insurer to deposit, or cause to be deposited, sufficient
funds to make payments due under this Policy.

                Subject to the terms of the Indenture, the Insurer shall be
subrogated to the rights of each Owner to receive payments under the Obligations
to the extent of any payment by the Insurer under the Policy.

Ladies and Gentlemen:

We have performed the procedures enumerated below, which were agreed to by
Redwood Trust, Inc. (the "Company") and First National Union Bank, solely to
assist you in connection with the requirement of the Trust Indenture (the
"Indenture") dated June 1, 1997 between Sequoia Mortgage Trust 1 (the "Issuer")
and First National Union Bank (the "Trustee") as described in Section 2.12(f) of
the Indenture with respect to the fair value to the Issuer of the collateral
being pledged under the Indenture. This engagement to apply agreed-upon
procedures was performed in accordance with standards established by the
American Institute of Certified Public Accountants. The sufficiency of these
procedures is solely the responsibility of the Company and the Trustee.
Consequently, we make no representation regarding the sufficiency of the
procedures described below either for the purpose for which this report has been
requested or for any other purpose.

The procedures and the associated findings are as follows:

1.      We traced and agreed the amounts of the whole loan pools listed on the
        attached Exhibit A under the heading "Face Value of Redwood's Mortgage
        Loans at June 1, 1997" to the remittance 


                                      IV-2
<PAGE>   190
        reports (maintained by the Company) received from the various servicers
        for the loan pools.

        Based on the above procedure no exceptions were noted.

2.      We recalculated the amounts shown on the attached Exhibit A under the
        heading "Face Value of Pledged Mortgages at June 1, 1997" as the
        difference between the amounts under the heading "Face Value of
        Redwood's Mortgage Loans at June 1, 1997" and "Loans Not Pledged".
        However, we make no comment with respect to any aspect related to the
        amounts listed under the heading "Loans Not Pledged".

        Based on the above procedure no exceptions were noted.

3.      We traced and agreed the prices shown on the attached Exhibit A under
        the heading "Price of Mortgage Loans" to the fax copy of the bid price
        from the respective servicers as received and maintained by the Company.
        In addition, we directly confirmed the bid prices with respective
        servicers for the following Redwood Asset No.'s: 2, 3, 4, 5, 7, 8, 9,
        11, 12, 13, 15, 16, 18, and 19. However, we make no comment with respect
        to the accuracy or appropriateness of the "Price of Mortgage Loans".

        Based on the above procedure no exceptions were noted.

4.      We recalculated the amounts under the heading "Fair Value of Pledged
        Mortgages" as shown on the attached Exhibit A, as the product of the
        amounts under the heading "Price of Mortgage Loans" and the heading
        "Loans Not Pledged".

        Based on the above procedure no exceptions were noted.

We were not engaged to, and did not, perform an audit, the objective of which
would be the expression of an opinion on the specified elements, accounts or
items. Accordingly, we do not express such an opinion. Had we performed
additional procedures, other matters might have come to our attention that would
have been reported to you.

This report is intended solely for the use of the Company and the Trustee and
should not be used by those who have not agreed to the 


                                      IV-3
<PAGE>   191
procedures and taken responsibility for the sufficiency of the procedures for
their purposes.

Issuer has pledged, transferred and assigned to the Trustee for the benefit of
the Bondholders and MBIA, as collateral for the payment of principal and
interest on the Bonds, all right, title and interest of the Issuer in and to the

delivered to the applicable Custodian, with respect to each Pledged Mortgage all
originals of the Mortgage Documents and any other instruments relating thereto

recorded assignments or (iii) the lender's title policy (together with all
riders thereto) satisfying the requirements set forth in the Custodial
Agreements, concurrently with the execution and delivery hereof, the Issuer
shall promptly deliver to the applicable Custodian, in accordance with the terms

original Mortgage or such interim assignment, as the case may be, with evidence

                                       31
<PAGE>   36
recording office, or a copy thereof, certified, if appropriate, by the relevant
recording office, but in no event shall any such delivery of the original

if appropriate, by the relevant recording office, be made later than one year
following the Closing Date, or, (y) in the case of such title policy, no later
than 120 days following the Closing Date; provided, however, that in the event
the Issuer is unable to deliver by such date each Mortgage and each such interim
assignment by reason of the fact that any such documents have not been returned

assignment, because the related Mortgage has not been returned by the
appropriate recording office, the Issuer shall deliver such documents to the
related Custodian as promptly as possible upon receipt thereof and, in any
event, within 180 days following the Closing Date. The Issuer shall forward or
cause to be forwarded to the related Custodian (a) from time to time additional

recording office requires the presentation of a "lost instruments affidavit and
indemnity" or any equivalent document, because only a copy of the Mortgage can
be delivered with the instrument of satisfaction or reconveyance, the Issuer
shall execute and deliver or cause to be executed and delivered such a document
to the public recording office. In the case where a public recording office
retains the original recorded Mortgage or in the case where a Mortgage is lost
after recordation in a public recording office, the Issuer shall deliver to the
related Custodian a copy of such Mortgage certified by such public recording
office to be a true and complete copy of the original recorded Mortgage.

Redwood shall (i) affix the Trustee's name to each assignment of Mortgage, as
the assignee thereof, (ii) cause such assignment to be in proper form for
recording in the appropriate public office


                                       32
<PAGE>   37
for real property records within thirty (30) days after receipt thereof and
(iii) cause to be delivered for recording in the appropriate public office for
real property records the assignments of the Mortgages to the Trustee, except
that, with respect to any assignment of a Mortgage as to which Redwood has not
received the information required to prepare such assignment in recordable form,
Redwood's obligation to do so and to deliver the same for such recording shall
be as soon as practicable after receipt of such information and in any event
within thirty (30) days after the receipt thereof, and Redwood need not cause to
be recorded any assignment which relates to a Pledged Mortgage in any
jurisdiction under the laws of which, as evidenced by an Opinion of Counsel,
from local counsel, delivered by Redwood (at Redwood's expense) to the Trustee
and MBIA in accordance with Section 3.11 of the Indenture, the recordation of
such assignment is not necessary to protect the Trustee's and the Bondholders'
and MBIA's interest in the related Pledged Mortgage; provided, however,
notwithstanding the delivery of any legal opinions, each assignment of Mortgage
shall be recorded upon the earliest to occur of (i) the direction by MBIA, (ii)
the occurrence of a Master Servicing Default hereunder or a default of under the
Indenture, or (iii) any bankruptcy, insolvency or foreclosure with respect to
the related Mortgagor.

                In the case of Pledged Mortgages that have been prepaid in full
as of the Closing Date, the Issuer, in lieu of delivering the above documents to
the related Custodian, will deposit in the Bond Account the portion of such
payment that is required to be deposited in the Bond Account pursuant to Section
3(f).

                Until the Bonds have been paid in full and the Issuer has
otherwise fulfilled its obligations under the Indenture, the Custodian shall
retain possession and custody of each Trustee Mortgage File in accordance with
and subject to the terms and conditions set forth in the Indenture and this
Agreement.

                (ii)    On the Closing Date, the Trustee shall receive a Trust
Receipt from each Custodian, whereby the Custodian acknowledges receipt of the
documents identified the applicable Trust Receipt and declares that it holds and
will hold such documents and the other documents delivered to it constituting
the Trustee Mortgage Files, and that it holds or will hold such other assets as
are included in the Trust Estate, in trust for 


                                       33
<PAGE>   38
the exclusive use and benefit of the Trustee on behalf of all present and future
Bondholders and MBIA. The related Custodian acknowledges that it will maintain
possession of the Mortgage Notes in the State(s) provided in the applicable
Custodial Agreement, unless otherwise permitted by the Trustee, the Rating
Agencies and MBIA.

                Each Custodian has agreed, pursuant to the related Custodial
Agreement, to execute and deliver on the Closing Date to the Issuer, MBIA and
the Trustee a Trust Receipt constituting an initial such receipt in the form
attached to the related Custodial Agreement. Based on its review and examination
required by and in accordance with the applicable Custodial Agreement, and only
as to the documents identified in such Initial Certification, the related
Custodian acknowledges that such documents appear regular on their face and
relate to such Pledged Mortgage; provided that the related Custodian shall be
under no obligation to ascertain that, except as therein provided, any
information set forth in said schedule is accurate. Neither the Trustee nor the
related Custodian shall be under any duty or obligation to inspect, review or
examine said documents, instruments, certificates or other papers to determine
that the same are genuine, enforceable or appropriate for the represented
purpose or that they have actually been recorded in the real estate records or
that they are other than what they purport to be on their face.

                Not later than 180 days after the Closing Date, the Custodian
shall deliver to the Issuer, the Insurer and the Trustee the applicable Trust
Receipt, with any applicable exceptions noted thereon.

                If, in the course of such review, a Custodian finds any document
constituting a part of a Trustee Mortgage File which does not meet the
requirements of the applicable Custodial Agreement, such Custodian shall list
such as an exception in the Final Certification; provided, however, that such
Custodian shall not make any determination as to whether (i) any endorsement is
sufficient to transfer all right, title and interest of the party so endorsing,
as noteholder or assignee thereof, in and to that Mortgage Note or (ii) that any
assignment is in recordable form or is sufficient to effect the assignment of
and transfer to the assignee thereof under the mortgage to which the assignment


                                       34
<PAGE>   39
relates. Redwood shall promptly correct or cure such defect within 90 days from
the date it was so notified of such defect and, if Redwood does not correct or
cure such defect within such period, Redwood shall either (a) substitute for the
related Pledged Mortgage a Replacement Pledged Mortgage, which substitution
shall be accomplished in the manner and subject to the conditions set forth in
Section 2(c)(iv), or (b) purchase such Pledged Mortgage from the Trustee within
60 days from the date Redwood was notified of such defect in writing at the
Purchase Price of such Pledged Mortgage. Any such substitution pursuant to (a)
above shall not be effected prior to the delivery to the Custodian of a Request
for Release. The Purchase Price for any such Pledged Mortgage purchased pursuant
to clause (b) shall be deposited by Redwood in the Bond Account on or prior to
the applicable Withdrawal Date in the month following the month of purchase and,
upon receipt of such deposit and the related Request for Release, the related
Custodian shall release the related Trustee Mortgage File to Redwood and shall
execute and deliver at Issuer's request such instruments of transfer or
assignment prepared by the Issuer and the Trustee, in each case without
recourse, as shall be necessary to vest in Redwood, or a designee, the Issuer's
and the Trustee's interest in any Pledged Mortgage released pursuant hereto.

                Each Custodian shall retain possession and custody of each
Trustee Mortgage File in accordance with and subject to the terms and conditions
set forth in the related Custodial Agreement. The Issuer or the Trustee shall
promptly deliver to the related Custodian, upon the execution or receipt
thereof, the originals of such other documents or instruments constituting the
Trustee Mortgage File as come into the possession of the respective Issuer or
Trustee from time to time.

                It is understood and agreed that the obligation of Redwood to
substitute for or to purchase any Pledged Mortgage which does not meet the
requirements set forth in the related Custodial Agreement shall constitute the
sole remedy respecting such defect available to the Trustee and any Bondholder
against Redwood.

performed in connection with a Pledged Mortgage, the related Servicer will
immediately notify the Trustee by delivering, or causing to be delivered, a
Request for Release, all in accordance with Section 8.08(c) of the Indenture.
Upon receipt of such request, the Trustee shall promptly notify the related

accordance with the terms of the applicable Custodial Agreement. Subject to the
further limitations set forth below, the related Servicer shall cause the
Trustee Mortgage File or documents so released to be returned to the Trustee
when the need therefor by the related Servicer no longer exists, unless the
Pledged Mortgage is liquidated and the proceeds thereof are deposited in the
Bond Account, in which case the related Servicer shall deliver to the Trustee a
Request for Release, signed by a Servicing Officer of the related Servicer.

                If the related Servicer at any time seeks to initiate a
foreclosure proceeding in respect of any Mortgaged Property as authorized by the
related Servicing Agreement, the related Servicer shall deliver or cause to be
delivered to the Trustee, for signature, as appropriate, any court pleadings,
requests for trustee's sale or other documents necessary to effectuate such
foreclosure or any legal action brought to obtain judgment against the Mortgagor
on the Mortgage Note or the Mortgage or to obtain a deficiency judgment or to
enforce any other remedies or rights provided by the Mortgage Note or the
Mortgage or otherwise available at law or in equity.

                        (iii)   The Issuer hereby makes the representations and
        warranties set forth in Schedule IV hereto, and by this reference
        incorporated herein, to the Trustee and the Master Servicer, as of the
        Closing Date.

                        (iv)    Upon discovery by any of the parties hereto or
        MBIA, of a breach of a representation or warranty (without regard to any
        limitation regarding the knowledge of Redwood contained therein)
        described in Section 2(c)(ii) that materially and adversely affects the
        value of any Pledged Mortgage or the interests of the Bondholders or
        MBIA in any Pledged Mortgage, the party discovering such breach shall
        give prompt notice thereof to the other parties and MBIA. Redwood hereby
        covenants that within 90 days of the earlier of its discovery or its
        receipt of written notice from any party of a breach of any
        representation or warranty (without regard to any limitation regarding
        the knowledge of Redwood contained therein) made pursuant to Section
        2(c)(ii) which materially and adversely affects the value of any Pledged
        Mortgage or the interests of the Bondholders or MBIA, in any Pledged
        Mortgage, it shall cure such breach in all material respects, and if
        such breach is not so cured, shall, (i) remove such Pledged Mortgage (a
        "Deleted Pledged Mortgage") from the Trust Estate and substitute in its
        place a Replacement Pledged Mortgage, in the manner and subject to the
        conditions set forth in this Section 2(c); or (ii) purchase the affected
        Pledged Mortgage or Pledged Mortgages from the Issuer with the Trustee
        releasing its lien thereon at the Purchase Price in the manner set forth
        below; provided, however, that any such substitution pursuant to (i)
        above shall not be effected prior to the delivery to the Trustee of a
        Request for Release, and the Trustee Mortgage File for any such
        Replacement Pledged Mortgage. Redwood shall promptly reimburse the
        Trustee or MBIA for any expenses reasonably incurred by the Trustee or
        MBIA in respect of enforcing the remedies for such breach.

                With respect to the representations and warranties described in
        this Section 2(c) which are made to the best of Redwood's knowledge, if
        it is discovered by either the Issuer or the Trustee that the substance
        of such representation and warranty is inaccurate and such inaccuracy
        materially and adversely affects the value of any Pledged 


                                       38
<PAGE>   43
        Mortgage, the interests of the Bondholders or MBIA therein,
        notwithstanding Redwood's lack of knowledge with respect to the
        substance of such representation or warranty, such inaccuracy shall be
        deemed a breach of the applicable representation or warranty.

                With respect to any Replacement Pledged Mortgage or Mortgages,
        Redwood shall deliver to the Custodian for the benefit of the
        Bondholders and MBIA the Mortgage Note, the Mortgage, the related
        assignment of the Mortgage, and such other documents and agreements as
        are required by the Custodial Agreements with the Mortgage Note endorsed
        and the Mortgage assigned as required by Custodial Agreement. No
        substitution is permitted to be made in any calendar month after the
        Withdrawal Date for such month. Scheduled Payments due with respect to
        Replacement Pledged Mortgages in the month of substitution shall not be
        part of the Trust Estate and will be retained by Redwood on the next
        succeeding Payment Date. For the Second Payment Date following the month
        of substitution, Available Funds will include the monthly payment due on
        any Deleted Pledged Mortgage for such month and thereafter Redwood shall
        be entitled to retain all amounts received in respect of such Deleted
        Pledged Mortgage.

                Redwood shall amend the Schedule of Pledged Mortgages for the
        benefit of the Bondholders and MBIA to reflect the removal of such
        Deleted Pledged Mortgage or Mortgages and the substitution of the
        Replacement Pledged Mortgage or Mortgages and the Issuer shall deliver
        the amended Schedule of Pledged Mortgages to the Trustee and MBIA. Upon
        such substitution, the Replacement Pledged Mortgage or Mortgages shall
        be subject to the terms of this Agreement in all respects, and Redwood
        shall be deemed to have made with respect to such Replacement Pledged
        Mortgage or Mortgages, as of the date of substitution, the
        representations and warranties made pursuant to Section 2(c)(ii) with
        respect to such Pledged Mortgage or Mortgages. Upon any such
        substitution and the deposit to the Bond Account of the amount required
        to be deposited therein in connection with such substitution as
        described in the following paragraph, the Trustee shall cause the
        release of the Trustee Mortgage File held by the applicable Custodian


                                       39
<PAGE>   44
        for the benefit of the Bondholders and MBIA relating to such Deleted
        Pledged Mortgage or Mortgages to Redwood and shall execute and deliver
        at Redwood's direction such instruments of transfer or assignment
        prepared by Redwood, in each case without recourse, as shall be
        necessary to vest title in Redwood, the Issuer's and the Trustee's
        interest in any Deleted Pledged Mortgage or Mortgages substituted for
        pursuant to this Section 2(c).

                For any month in which Redwood substitutes one or more
        Replacement Pledged Mortgages for one or more Deleted Pledged Mortgages,
        Redwood will determine the amount (if any) by which the aggregate
        principal balance of all such Replacement Pledged Mortgages as of the
        date of substitution is less than the aggregate Stated Principal Balance
        of all such Deleted Pledged Mortgages (after application of the
        scheduled principal portion of the monthly payments due in the month of
        substitution). The amount of such shortage (the "Substitution Adjustment
        Amount") shall be deposited into the Bond Account by Redwood on or
        before the related Withdrawal Date for the Payment Date in the month
        succeeding the calendar month during which the related Pledged Mortgage
        became required to be purchased or replaced hereunder.

                In the event that Redwood shall have purchased a Pledged
        Mortgage, the Purchase Price therefor shall be deposited in the Bond
        Account pursuant to Section 3(f) and in compliance with the provisions
        of Section 8.04 of the Indenture before the related Withdrawal Date for
        the Payment Date in the month following the month during which the
        Issuer became obligated hereunder to purchase or replace such Pledged
        Mortgage and upon such deposit of the Purchase Price and receipt of a
        Request for Release in the form attached to the related Custodial
        Agreement, the Trustee shall cause the release of the related Trustee
        Mortgage File held by the applicable Custodian for the benefit of the
        Bondholders and MBIA to Redwood, and the Trustee shall execute and
        deliver at Redwood's direction such instruments of transfer or
        assignment prepared by Redwood, in each case without recourse, as shall
        be necessary to transfer title from the Issuer and release of the
        Trustee's lien thereon pursuant to Sections 8.08(c) and 8.12 of the
        Indenture. It is understood and agreed that the obligation under this


                                       40
<PAGE>   45
        Agreement of Redwood to cure, purchase or replace any Pledged Mortgage
        as to which a breach has occurred and is continuing shall constitute the
        sole remedy against Redwood respecting such breach available to
        Bondholders or the Trustee on their behalf; provided, however, that
        Redwood will indemnify the Issuer and the Insurer for any damages caused
        by the breach of either of the following two representations: (1) none
        of the Pledged Mortgages are "consumer credit contracts" or "purchase
        money loans" for goods or services as such terms are defined in 16 C.F.R
        section 433.1 and (2) none of the Pledged Mortgages are "mortgages" as
        such term is defined in 15 U.S.C. 1602(aa).

                The representations and warranties made pursuant to this Section
        2(c) shall survive delivery of the respective Trustee Mortgage Files to
        the Custodian for the benefit of the Bondholders and MBIA, provided,
        however, that those made pursuant to Section 2(c)(ii)(A) shall not be
        assignable by the Trustee without Redwood's express written permission.

        (d)     Covenants of the Master Servicer.

        The Master Servicer hereby covenants to the Issuer and the Trustee as
follows:

                (i)     the Master Servicer shall comply in the performance of
        its obligations under this Agreement with all reasonable rules and
        requirements of MBIA under the MBIA Policy; and

                (ii)    no written information, certificate of an officer,
        statement furnished in writing or written report delivered to the
        Issuer, any affiliate of the Issuer, MBIA or the Trustee and prepared by
        the Master Servicer pursuant to this Agreement will contain any untrue
        statement of a material fact or omit to state a material fact necessary
        to make such information, certificate, statement or report not
        misleading.

3.      General Duties of the Master Servicer.

        (a)     Master Servicer to Master Service Pledged Mortgages.

                The parties agree that, subject to the provisions of Section 8
hereof, the Master Servicer shall master service the Pledged Mortgages in
accordance with the terms of this Agreement. In that regard, the Master Servicer
shall supervise, administer, monitor and oversee the servicing of the Mortgage
Loans by each Servicer pursuant to the terms of its Servicing Agreement, on
behalf of the Issuer and the Trustee and for the benefit of the Bondholders and
MBIA, in accordance with this Agreement and applicable laws and regulations and
giving due consideration to customary and usual standards of practice of prudent
mortgage lenders and master servicers. In addition, the Master Servicer shall
(i) oversee and consult with each Servicer as appropriate from time to time to
fulfill the Master Servicer's obligations hereunder, (ii) receive, review and
evaluate all reports, information and other data and documents provided to the
Master Servicer by each Servicer and (iii) otherwise exercise its best efforts,
as more fully set forth in Section 3(b), to cause each Servicer to perform and
observe the covenants, obligations and conditions required to be performed under
its Servicing Agreement.

        (b)     Servicing; Enforcement of the Obligations of Servicers.

                (i)     Redwood has entered into or is the assignee of the
        Servicing Agreements listed on Schedule V hereto, and on the Closing
        Date it assigned all of its rights, title and interest in and to such
        Servicing Agreements to the Issuer. The Issuer, the Trustee and the
        Bondholders, by their purchase and acceptance of the Bonds, acknowledge
        and agree that the Pledged Mortgages shall be serviced by the Servicers
        in accordance with the terms and provisions of the Servicing Agreements
        and authorize the Master Servicer to enforce the Servicing Agreements
        pursuant to the terms of this Agreement. Redwood has (i) provided to
        each Servicer notice of the assignment of the related Servicing
        Agreement to the Issuer, in accordance with the provisions of such
        Servicing Agreement, and of the appointment of Norwest as Master
        Servicer hereunder, and has instructed each Servicer to remit all
        amounts required to be paid to the owner of the 


                                       42
<PAGE>   47
        related Pledged Mortgages under its Servicing Agreement to the Master
        Servicer, and (ii) has received from each Servicer acknowledgement of
        such assignment and appointment and of the Master Servicer's authority
        to enforce the related Servicing Agreement on behalf of the Trust and
        such Servicer's agreement to remit all such amounts to the Master
        Servicer.

                (ii)    As part of its master servicing activities hereunder,
        the Master Servicer, for the benefit of the Trustee and the Bondholders
        and MBIA, shall use its best reasonable efforts to enforce the
        obligations of each Servicer under the related Servicing Agreement, to
        the extent that the non-performance of any such obligation would have
        material and adverse effect on a Pledged Mortgage. Such enforcement,
        including, without limitation, the legal prosecution of claims,
        termination of Servicing Agreements and the pursuit of other appropriate
        remedies, shall be in such form and carried out to such an extent and at
        such time as the Master Servicer, in its good faith business judgment,
        would require were it the owner of the related Pledged Mortgages;
        provided, that, the Master Servicer shall be entitled to be reimbursed
        for the costs and expenses associated with any such enforcement (i) from
        a general recovery resulting from such enforcement to the extent, if
        any, that such recovery exceeds all amounts due in respect of the
        related Pledged Mortgage, (ii) from a specific recovery of costs,
        expenses or attorneys fees against the party against whom such
        enforcement is directed, and (iii) if the amounts described in the
        preceding clauses (i) and (ii) are insufficient to reimburse the Master
        Servicer for all amounts so advanced, then the outstanding amount of any
        such advance shall be reimbursable out of amounts in the Bond Account.
        Provided no MBIA Default has occurred and is continuing, the Master
        Servicer shall consult with MBIA prior to the initiation of any
        enforcement measure under this Section 3(b)(ii). In the event the Master
        Servicer and MBIA cannot agree on the enforcement measure, the decision
        of the Master Servicer shall control; provided, that MBIA shall have the
        right to control the time, method and place of conducting all proceeding
        related to such enforcement measure and if the enforcement measure is
        legal prosecution 


                                       43
<PAGE>   48
        of a claim against a Servicer, the provisions of Section 7(c)(ii) shall
        apply.

        (c)     Successor Servicers.

                (i)     The Issuer as owner of the Pledged Mortgages and the
        Trustee as lienholder with respect thereto, pursuant to the Servicing
        Agreements, hereby authorize and appoint the Master Servicer as their
        agent to exercise all rights of the party entitled to exercise ownership
        rights with respect to the Pledged Mortgages in accordance with the
        terms of the Servicing Agreements, including, without limitation, the
        power to terminate the Servicing Agreement and the related Servicers
        according to the terms and conditions of such Servicing Agreements,
        without any limitation by virtue of this Agreement; provided, however,
        that in the event of termination of any Servicing Agreement by the
        Master Servicer or the related Servicer, the Master Servicer shall
        either act as servicer of the related Pledged Mortgages in accordance
        with the terms of the related Servicing Agreement (with such
        modifications as described in this Agreement) or enter into a Servicing
        Agreement with a successor Servicer acceptable to MBIA which will be
        bound by the terms of the related Servicing Agreement in accordance with
        the terms of related Servicing Agreement (with such modifications as
        described in this Agreement). If the Master Servicer or any affiliate of
        the Master Servicer acts as servicer, it will not assume liability for
        the representations and warranties of the Servicer which it replaces.

                (ii)    Notwithstanding the provisions of this Section 3 or of
        any Servicing Agreement, the Master Servicer shall be under no
        obligation, either as Master Servicer or as successor Servicer under a
        Servicing Agreement, to purchase any Pledged Mortgage including any
        Converted Pledged Mortgages.

        (d)     Rights of the Issuer and the Trustee in Respect of the Master
                Servicer.

        The Issuer may, but is not obligated to, enforce the obligations of the
Master Servicer hereunder and may, but is not obligated to, perform, or cause a
designee to perform, any 

                                       44
<PAGE>   49
defaulted obligation of the Master Servicer hereunder and in connection with any
such defaulted obligation to exercise the related rights of the Master Servicer
hereunder; provided that the Master Servicer shall not be relieved of any of its
obligations hereunder by virtue of such performance by the Issuer or its
designee. Neither the Trustee nor the Issuer shall have any responsibility or
liability for any action or failure to act by the Master Servicer nor shall the
Trustee or the Issuer be obligated to supervise the performance of the Master
Servicer hereunder or otherwise.

        (e)     Trustee to Act as Master Servicer.

                In the event that the Master Servicer shall for any reason no
longer be the Master Servicer hereunder (including by reason of a Master
Servicing Default), unless a successor Master Servicer acceptable to MBIA has
been appointed, the Trustee or its successor shall thereupon assume all of the
rights and obligations of the Master Servicer hereunder arising thereafter,
except that the Trustee shall not be (i) liable for losses of the Master
Servicer pursuant to Section 3(f)(ix) or any acts or omissions of the
predecessor Master Servicer hereunder, (ii) obligated to make Servicing Advances
or Master Servicing Advances if it is prohibited from doing so by applicable
law, or (iii) deemed to have made any representations and warranties of the
Master Servicer hereunder. Any such assumption shall be subject to Section 8(b).
If the Master Servicer shall for any reason no longer be the Master Servicer
(including by reason of any Master Servicing Default), unless a successor Master
Servicer acceptable to MBIA has been appointed, the Trustee or its successor
shall succeed to any rights of the Master Servicer under this Agreement and any
obligations of the Master Servicer under this Agreement arising thereafter
including, with respect to the Servicing Agreements, all rights and obligations
of the Master Servicer related thereto as contemplated by Section 3(b).

        (f)     Collection of Pledged Mortgage Payments; Bond Account;
                Distribution Account.

                (i) The Master Servicer shall make reasonable efforts to collect
        all payments called for under the terms and provisions of the Servicing
        Agreements from the related Servicers.


                                       45
<PAGE>   50
                (ii) The Master Servicer shall establish and maintain a Bond
        Account, which shall be an Eligible Account, into which the Master
        Servicer shall deposit or cause to be deposited on a daily basis, or to
        the extent same day deposit is unavailable, within one Business Day of
        receipt, provided, that, any investment earnings accrued between receipt
        by the Master Servicer and deposit in the Bond Account, will be
        deposited into the Bond Account, except as otherwise specifically
        provided herein, the following payments and collections remitted by
        Servicers or received by it in respect of Pledged Mortgages subsequent
        to the Cutoff Date (other than in respect of principal and interest due
        on the Pledged Mortgages on or before the Cut-off Date) and the
        following amounts required to be deposited hereunder:

        (A)     all payments on account of principal on the Pledged Mortgages,
                including Principal Prepayments and the principal component of
                any Servicer Advance remitted to it by the Servicers;

        (B)     all payments on account of interest on the Pledged Mortgages,
                net of the sum of the related Servicing Fee, and the interest
                component of any Servicer Advance remitted to it by the
                Servicers;

        (C)     all Insurance Proceeds and Liquidation Proceeds;

        (D)     any other payments, collections and other amounts remitted to it
                by a Servicer pursuant to the related Servicing Agreement in
                respect of the Pledged Mortgages;

        (E)     any amount required to be deposited by Redwood in connection
                with any realized losses on Permitted Investments pursuant to
                clause (ix) of this Section 3(f);

        (F)     all Purchase Prices from Redwood or any other person and all
                Substitution Adjustment Amounts;

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

                The foregoing requirements for remittance by the Master Servicer
        shall be exclusive, it being understood and agreed that, without
        limiting the generality of the foregoing, payments in the nature of
        prepayment penalties, late payment charges or assumption fees, if
        collected, need not be remitted by the Master Servicer. In the event
        that the Master Servicer shall remit any amount not required to be
        remitted, it may at any time withdraw or direct the institution
        maintaining the Bond Account to withdraw such amount from the Bond
        Account, any provision herein to the contrary notwithstanding. Such
        withdrawal or direction may be accomplished by delivering written notice
        thereof to the Trustee or such other institution maintaining the Bond
        Account which describes the amounts deposited in error in the Bond
        Account. The Master Servicer shall maintain adequate records with
        respect to all withdrawals made pursuant to this Section 3(f). All funds
        deposited in the Bond Account shall be held in trust for the Bondholders
        and MBIA until withdrawn in accordance with clauses (iii), (iv) and (vi)
        below.

                (iii) Permitted Withdrawals from the Bond Account.

                The Master Servicer may from time to time make withdrawals from
        the Bond Account for the following purposes:

        (A)     to reimburse the Master Servicer or Servicer, as applicable, for
                unreimbursed Master Servicer Advances, Advances, or Servicing
                Advances made by it, such right of reimbursement pursuant to
                this subclause (iii) being limited to amounts received on the
                Pledged Mortgage(s) (including Insurance Proceeds and
                Liquidation Proceeds) in respect of which any such Master
                Servicer Advance or Servicing Advance was made;

        (B)     to reimburse the related Servicer or Master Servicer for any
                Nonrecoverable Advance previously made;

<PAGE>   52


        (C)     to pay to the purchaser, with respect to each Pledged Mortgage
                or property acquired in respect thereof that has been purchased
                pursuant to Section 2(a)(ii), 2(c)(iv) or 4(c), all amounts
                received thereon after the date of such purchase;

        (D)     to reimburse the Master Servicer for expenses incurred and

                and to pay to the Trustee amounts due to it pursuant to Section
                6.07(2) and (3) of the Indenture up to an amount not to exceed
                $150,000 per annum in any calendar year;

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

        (F)     to withdraw investment earnings payable to Redwood;

        (G)     on each of the Non-RFC Withdrawal Date and the RFC Withdrawal
                Date to withdraw Available Funds for such Payment Date, to the
                extent on deposit, and remit such amount to the Distribution
                Amount; and

        (H)     to clear and terminate the Bond Account upon termination of this
                Agreement pursuant to Section 9(a).

                The Master Servicer shall keep and maintain separate accounting,
        on a Pledged Mortgage by Pledged Mortgage basis, for the purpose of
        justifying any withdrawal from the Bond Account pursuant to such
        subclauses (A), (B), (D) and (E). Prior to making any withdrawal from
        the Bond Account pursuant to subclause (B), the Master Servicer shall
        deliver to the Trustee an Officer's Certificate of a Servicing Officer
        indicating the amount of any previous Master Servicer Advance, Advances,
        or Servicing Advance determined by the Master Servicer or the Servicer
        to be a Nonrecoverable Advance and identifying the related Pledged
        Mortgage(s).

                (iv) On each Withdrawal Date, after payment of any amounts
described in clauses (A) through (H) of Section 3(f)(iii) of this Agreement, the
Master Servicer will withdraw from the Bond Account the Available Funds for the
related Payment Date (other than any amounts in respect of investment losses on

to Section 3(f)(ix)), and will deposit such amount in the Distribution Account.

                (v) On the Calculation Date, the Master Servicer will deposit

to claims under the MBIA Policy) and distribute such funds, and the Trustee upon
being so instructed will distribute such funds on each such Payment Date, in the
following order of priority in each case, to the extent of funds remaining:

                any shortfall in such amounts to be allocated between each such
                Class on a pro rata basis (based on the ratio of each such
                amount to the total of such amounts);

        (C)     the Class A-1 Bondholders' Interest Carryover and the Class A-2
                Bondholders' Interest Carryover for such Payment Date to the

<PAGE>   54


                the Class A-1 Bondholders, respectively, with any shortfall in
                such amounts to be allocated between each such Class on a pro
                rata basis (based on the ratio of each such amount to the total
                of such amounts);

        (D)     the Basic Principal Payment Amount for such Payment Date to the
                Class A-1 Bondholders and Class A-2 Bondholders, pro rata based
                on the respective Principal Amounts of each such Class;

        (E)     the aggregate amount of previously unreimbursed Insurer

                the Class A-1 Bondholders and the Class A-2 Bondholders pro rata
                based on the respective Principal Amounts of each such Class;

        (G)     to reimburse the Master Servicer for expenses incurred by it and
                reimbursable pursuant to Section 3(b)(ii) and Section 7(c), to
                the extent that any amounts exceed $150,000 in any calendar year
                and only that portion of such amounts in excess of $150,000
                incurred during such calendar year and to pay to the Trustee
                amounts due to it pursuant to Section 6.07(2) and (3) of the

                any amounts due and owing to the Manager under the Management
                Agreement other than the Management Fee; and

        (H)     the remaining amount of Available Funds on deposit in the
                Distribution Account, if any, for such Payment Date, to the

                                       50

                appointed pursuant to the Deposit Trust Agreement (which shall
                initially be the Trustee) for the distribution of such amount
                pursuant to the terms of such agreement on the Investor
                Certificates.

        The Master Servicer may conclusively rely on written notice from the
Issuer as to all payment instructions with respect to the amounts to be
distributed to the Certificate Paying Agent pursuant to clause (H) above.

              (viii) [Reserved.]

                (ix) Each institution at which the Bond Account and the
        Distribution Account is maintained shall invest the funds therein as
        directed in writing by Redwood or by the Master Servicer, respectively,
        in Permitted Investments, which shall mature not later than (i) in the
        case of the Bond Account, the Non-RFC Withdrawal Date with respect to
        Available Funds to be withdrawn on that date and the RFC Withdrawal Date
        with respect to Available Funds to be withdrawn on that date, and (ii)
        in the case of the Distribution Account, the Business Day next preceding
        the related Payment Date (except that if the Distribution Account is
        held at the Trustee, any Permitted Investment shall mature not later
        than such Payment Date) and, in each case, shall not be sold or disposed
        of prior to its maturity. All such Permitted Investments shall be made
        in the name of the Trustee, for the benefit of the Bondholders and MBIA.
        All income and gain (net of any losses) realized from any such
        investment of funds on deposit in the Bond Account and the Distribution
        Account shall be for the benefit of Redwood or the Master Servicer,
        respectively, and shall be remitted to it monthly as provided herein.
        The amount set forth in the preceding sentence with respect to the Bond
        Account shall be compensation payable to Redwood as manager of the Trust
        under the Management Agreement, in addition to the Management Fee, and
        with respect to the Distribution Account shall be the "Master Servicing
        Fee" for such period and the related Payment Date. The amount of any
        realized losses in the Bond Account or the Distribution Account incurred
        in any such account in respect of any such investments shall promptly be
        deposited by Redwood in the Bond Account or the Master Servicer in the
        Distribution 



                                       51

        Account, as applicable. The Trustee in its fiduciary capacity shall not
        be liable for the amount of any loss incurred in respect of any
        investment or lack of investment of funds held in the Bond Account or
        the Distribution Account and made in accordance with this Section 3(f).

                (x) The Master Servicer shall give notice to the Trustee, the
        Issuer, MBIA and each Rating Agency of any proposed change of the
        location of the Bond Account not later than 30 days and not more than 45
        days prior to any change thereof.

        (g)     Access to Certain Documentation and Information Regarding the
                Pledged Mortgages.

               The Master Servicer shall afford the Issuer, MBIA and the Trustee
reasonable access to all records and documentation regarding the Pledged
Mortgages and all accounts, insurance information and other matters relating to
this Agreement maintained by the Master Servicer, such access being afforded
without charge, but only upon reasonable request and during normal business
hours at the office designated by the Master Servicer. The Master Servicer shall
provide MBIA with a copy of all reports that it receives from the Servicers.

               Upon reasonable advance notice in writing, the Master Servicer
will provide to each Bondholder which is a savings and loan association, bank or
insurance company certain reports and reasonable access to information and
documentation regarding the Pledged Mortgages maintained by the Master Servicer
sufficient to permit such Bondholder to comply with applicable regulations of
the OTS or other regulatory authorities with respect to investment in the Bonds;
provided that the Master Servicer shall be entitled to be reimbursed by each
such Bondholder for actual expenses incurred by the Master Servicer in providing
such reports and access.

        (h)     Determination of LIBOR, the Fed Funds Rates and Certain Other
                Amounts.

                (i) With respect to the Class A-1 Bonds, LIBOR will be
        determined as follows:



                                       52
<PAGE>   57


        On the second LIBOR Business Day prior to the commencement of each
Interest Accrual Period after the Initial Accrual Period for the Class A-1 Bonds
(each a "LIBOR Rate Determination Date"), the Master Servicer will determine
LIBOR.

        "LIBOR" means, as of any LIBOR Rate Determination Date, the rate for
deposits in United States dollars for a period equal to the relevant Interest
Accrual Period (commencing to the first day of such Interest Accrual Period)
which appears in the Telerate Page 3750 as of 11:00 a.m., London time, on such
date. If such rate does not appear on Telerate Page 3750, the rate for that day
will be determined on the basis of the rates at which deposits in United States
dollars are offered by the Reference Banks at approximately 11:00 a.m., London
time, on that day to prime banks in the London interbank market for a period
equal to the relevant Interest Accrual Period (commencing on the first day of
such Interest Accrual Period). The Master Servicer will request the principal
London office of each of the Reference Banks to provide a quotation of its rate.
If at least two such quotations are provided, the rate for that day will be the
arithmetic mean of the quotations. If fewer than two quotations are provided as
requested, the rate for that day will be the arithmetic mean of the rates quoted
by major banks in The City of New York, selected by the Master Servicer, at
approximately 11:00 a.m., New York City time, on that day for loans in United
States dollars to leading European banks for a period equal to the relevant
Interest Accrual Period (commencing on the first day of such Interest Accrual
Period).

        "Telerate Page 3750" means the display page currently so designated on
the Dow Jones Telerate Service (or such other page as may replace that page on
that service for the purpose of displaying comparable rates or prices) and
"Reference Banks" means leading banks selected by the Master Servicer and
engaged in transactions in Eurodollar deposits in the international Eurocurrency
market.

        The Class A-1 Interest Rate for the First Payment Date will equal
6.02844% per annum.

        The establishment of LIBOR by the Master Servicer and the Master
Servicer's subsequent calculation of the Bond Interest Rate on the Class A-1
Bonds for the Interest Accrual Period, in 


                                       53
<PAGE>   58

the absence of willful misconduct, bad faith or manifest error, will be final
and binding. The Bond Interest Rate on the Class A-1 Bonds for any applicable
Interest Accrual Period may be obtained by telephoning the Master Servicer at
(410) 884-2000.

                  (ii) The Fed Funds Rate will reset each Fed Funds Business Day
        other than the last Fed Funds Business Day of each Fed Funds Calculation
        Period (each, a "Fed Funds Interest Reset Date"). The Fed Funds Rate in
        effect on each day of each Fed Funds Calculation Period will be (a) if
        such day is a Fed Funds Interest Reset Date, the Fed Funds Rate
        determined as of such Fed Funds Business Day (each a "Fed Funds Interest
        Determination Date"), or (b) if such day is not a Fed Funds Interest
        Reset Date, the Fed Funds Rate in effect on the immediately preceding
        Fed Funds Interest Reset Date.

        The "Fed Funds Rate", with respect to a Fed Funds Interest Reset Date,
means (in the following order of priority):

                (1)   the rate with respect to the related Fed Funds Interest
                      Determination Date (expressed as a percentage per annum)
                      that appears opposite the caption "Federal Funds
                      Effective" on Telerate Page 120 (as defined below) as of
                      11:00 a.m., New York City time on such Fed Funds Interest
                      Reset Date;

               (2)    if such rate does not appear on Telerate Page 120
                      as of 11:00 a.m., New York City time, on such Fed
                      Funds Interest Reset Date, then the Fed Funds Rate
                      with respect to such Fed Funds Interest Reset Date
                      will be the rate with respect to the related Fed
                      Funds Interest Determination Date (expressed as a
                      percentage per annum) that appears on Reuters
                      Screen NYAA Page (as defined below) as of 11:00
                      a.m., New York City time, on such Fed Funds
                      Interest Reset Date;

               (3)    if such rate does not appear on Reuters Screen
                      NYAA Page as of 11:00 a.m., New York City time, on
                      such Fed Funds Interest Reset Date, then the
                      Master Servicer will request three leading brokers
                      of Federal Funds transactions in The City of New


                                       54
<PAGE>   59


                      York to provide the rate (expressed as a
                      percentage per annum) for the last transaction in
                      overnight Federal Funds arranged by such broker on
                      the related Fed Funds Interest Determination Date.
                      If rates are provided by such three brokers, then
                      the Fed Funds Rate with respect to such Fed Funds
                      Interest Reset Date will be the arithmetic mean
                      (rounded to the nearest one hundred-thousandth of
                      one percentage point with five one-millionths of
                      one percentage point rounded upwards) of such
                      rates; and

               (4)    if fewer than three such rates are provided, then
                      the Fed Funds Rate with respect to such Fed Funds
                      Interest Reset Date will be the Fed Funds Rate for
                      the preceding Fed Funds Interest Reset Date (or,
                      in the case of the first Fed Funds Interest Reset
                      Date, the immediately preceding Fed Funds Business
                      Day on which a rate appeared on Telerate Page 120
                      as described in (1) above).

        If a rate that initially appears on Telerate Page 120 or Reuters Screen
NYAA Page, as the case may be, as of 11:00 a.m., New York City Time, on the
applicable Fed Funds Interest Reset Date is superseded on Telerate Page 120 or
Reuters Screen NYAA Page, as the case may be, by a corrected rate before 12:00
noon, New York City time, on such Fed Funds Interest Reset Date, such corrected
rate as so superseded on the applicable page shall be the applicable rate for
calculating the applicable Fed Funds Rate for such Fed Funds Interest
Determination Date.

        "Reuters Screen NYAA Page" means the display designated as page "Reuters
Screen NYAA Page" on the Reuters Monitor Money Rates Service (or such other page
selected by the Master Servicer as may replace the NYAA page on that service for
the purpose of displaying Federal Funds rates).

        "Telerate Page 120" means the display designated as "Page 120" on the
Dow Jones Telerate Service (or such other page selected by the Master Servicer
as may replace Page 120 on that service for the purpose of displaying daily
Federal Funds rates).


                                       55
<PAGE>   60

        All percentages resulting from a calculation with respect to the Fed
Funds Rate or the Class A-2 Interest Rate based on the Fed Funds Rate for any
Interest Accrual Period will be rounded by the Master Servicer to the nearest
one hundred-thousandth of a percentage point, with five one-millionths of a
percentage point rounded upwards (e.g., 9.876545% (or .09876545) would be
rounded to 9.87655% (or .0987655)), and all dollar amounts used in or resulting
from such calculation will be rounded to the nearest cent, with one-half cent
rounded upwards.

        The establishment of Fed Funds Rate by the Master Servicer and the
Master Servicer's subsequent calculation of the Class A-2 Interest Rate and the
Fed Funds Average Rate for the Interest Accrual Period, in the absence of
willful misconduct, bad faith or manifest error, will be final and binding. The
Class A-2 Interest Rate and the applicable Fed Funds Rate and Fed Funds Average
Rate will be made available by the Master Servicer to persons telephoning the
Master Servicer at 410-884-2000.

        (i)    Access to Certain Documentation.

               The Master Servicer shall provide to the OTS and the FDIC and to
comparable regulatory authorities supervising Holders of Bonds and the examiners
and supervisory agents of the OTS, the FDIC and such other authorities, access
to the documentation regarding the Pledged Mortgages within the possession of
the Master Servicer and required by applicable regulations of the OTS and the
FDIC. Such access shall be afforded without charge, but only upon reasonable and
prior written request and during normal business hours at the offices designated
by the Master Servicer. Nothing in this Section 3(i) shall limit the obligation
of the Master Servicer to observe any applicable law prohibiting disclosure of
information regarding the Mortgagors and the failure of the Master Servicer to
provide access as provided in this Section 3(i) as a result of such obligation
shall not constitute a breach of this Section 3(i).

        (j)      Annual Statement as to Compliance.

               The Master Servicer shall deliver to the Issuer, MBIA and the
Trustee on or before 120 days after the end of the Master Servicer's fiscal
year, commencing with its 1997 fiscal year, an Officer's Certificate stating, as
to the signer thereof, that (i)


                                       56
<PAGE>   61


a review of the activities of the Master Servicer during the preceding calendar
year and of the performance of the Master Servicer under this Agreement has been
made under such officer's supervision, (ii) to the best of such officer's
knowledge, based on such review and following reasonable inquiry, no Default or
Event of Default has occurred under this Agreement or the Insurance Agreement to
which it is a party, or if a Default or Event of Default has occurred,
specifying the nature thereof and, if the Master Servicer has a right to cure
pursuant to Section 7(a) of the Master Servicing Agreement, stating in
reasonable detail (including, if applicable, any supporting calculations) the
steps, if any, being taken by the Master Servicer to cure such Default or Event
of Default or to otherwise comply with the terms of this Agreement or
Transaction Document to which such Default or Event of Default relates, (iii) to
the best of such officer's knowledge, each Servicer has fulfilled all its
obligations under its Servicing Agreement throughout such year, or, if there has
been a default in the fulfillment of any such obligation, specifying each such
default known to such officer and the nature and status thereof and (iv) the
Master Servicer has in full force and effect a blanket fidelity bond (or direct
surety bond) and an errors and omissions insurance policy in accordance with the
terms and requirements of Section 3(l) of the Master Servicing Agreement. The
Master Servicer shall promptly forward to the Issuer, MBIA and the Trustee
copies of the annual compliance statements delivered to the Master Servicer
pursuant to the Servicing Agreements. The Trustee shall forward a copy of each
such statement to each Rating Agency.

        (k) The Master Servicer hereby acknowledges that concurrently with the
execution of this Agreement, the Trustee has acquired and holds a security
interest in the Trustee Mortgage Files and in all Pledged Mortgages represented
by such Trustee Mortgage Files and in all funds now or hereafter held by, or
under the control of, the Master Servicer that are collected by the Master
Servicer in connection with the Pledged Mortgages, whether as Scheduled
Payments, as Principal Prepayments, or as Liquidation Proceeds or Insurance
Proceeds, and in all proceeds of the foregoing and proceeds of proceeds (but
excluding any Master Servicing Fees and any other amounts or reimbursements to
which the Master Servicer is entitled under this Agreement). The Master Servicer
agrees that so long as the Pledged Mortgages are assigned to the Trustee, all
Trustee Mortgage Files (and any 


                                       57
<PAGE>   62


documents or instruments constituting a part of such files), and such funds
which come into the possession or custody of, or which are subject to the
control of, the Master Servicer shall be held by the Master Servicer for and on
behalf of the Trustee as the Trustee's agent and bailee for purposes of
perfecting the Trustee's security interest therein, as provided by Section 9-305
of the Uniform Commercial Code of the state in which such property is located,
or by other laws, as specified in Section 8.10 of the Indenture. The Master
Servicer hereby accepts such agency and acknowledges that the Trustee, as
secured party, will be deemed to have possession at all times of all Trustee
Mortgage Files and any other documents or instruments constituting a part of
such files, such funds and other items for purposes of Section 9-305 of the
Uniform Commercial Code of the state in which such property is held by the
Master Servicer. The Master Servicer also agrees that it shall not create, incur
or subject any Trustee Mortgage File or other documents relating to a Pledged
Mortgage which are in the possession of the Master Servicer with respect to each
Pledged Mortgage or any funds that are deposited in the Distribution Account,
the Bond Account, or any funds that otherwise are or may become due or payable
to the Trustee for the benefit of the Bondholders and MBIA, to any claim, lien,
security interest, judgment, levy, writ of attachment or other encumbrance
(other than the claims of the Bondholder and MBIA), or assert by legal action or
otherwise any claim or right of set-off against any such Trustee Mortgage File
or any funds collected or held by, or under the control of, the Master Servicer
from time to time in respect of a Pledged Mortgage.

        (l)    Errors and Omissions Insurance; Fidelity Bond.

               The Master Servicer shall obtain and maintain in force, (a) a
policy or policies of insurance covering errors and omissions in the performance
of its obligations as Master Servicer hereunder, and (b) a fidelity bond in
respect of its officers, employees and agents. In the event that any such policy
or bond ceases to be in effect, the Master Servicer shall obtain a comparable
replacement policy or bond. The coverage under each such policy and bond shall
be in such an amount as is customary therefor for the business of master
servicing residential mortgage loans.

        allocation thereof as between principal and interest;

        calendar months since the Cut-off Date, whichever is less and in each
        case ending with the second calendar month prior to the month of such
        Payment Date, the aggregate dollar amount of the Scheduled Payments (A)
        due on all Outstanding Pledged Mortgages on each of the Due Dates in
        each such month and (B) delinquent 60 days or more on each of the Due
        Dates in each such month;

                  (xi) with respect to any Pledged Mortgage that became a REO
        Property during the second preceding calendar month, the loan number and
        Stated Principal Balance of such Pledged Mortgage as of the close of
        business on the Calculation Date preceding such Payment Date and the

                  (xii) the total number and principal balance of any REO
        Properties (and market value, if available) as of the close of business

                  (xvi) the amount of the Serious Delinquencies.

               Within a reasonable period of time after the end of each calendar
year, the Master Servicer shall furnish to each Person who at any time during
the calendar year was a Bondholder and has requested such information and to
MBIA, a statement containing the information set forth in subclauses (i), (ii)
and (vi) of this Section 3(m) aggregated for such calendar year or applicable
portion thereof during which such Person was a Bondholder. Such obligation of
the Master Servicer shall be deemed to have been satisfied to the extent that
substantially comparable information shall be provided by the Master Servicer
pursuant to any requirements of the Code as from time to time in effect.

        The Master Servicer upon request, as required by law, shall supply to
the Trustee at least fifteen calendar days prior to any applicable filing date
prescribed by law of Internal Revenue Service regulation, and the Trustee, as
agent for the Issuer, and upon receipt from the Master Servicer, shall transmit
by mail to each Bondholder, as such Bondholder's name and address appears in the
Bond Register, and to the Internal Revenue Service, within the time limits
prescribed by law, the amount of interest and original issue discount (which
original issue discount shall be calculated by the Master Servicer), if any,
paid or accrued with respect to Bonds held by such Bondholder.

        (n) As required by the Code or the Treasury regulations thereunder, the
Master Servicer shall supply to the Trustee and the Trustee, as agent for the
Master Servicer, and upon receipt from the Master Servicer, shall transmit by
mail to each Bondholder appropriate tax accounting information, and any other
tax accounting information that a Bondholder reasonably requests, to enable it
to prepare its tax returns.

        (o)    Claims Upon the MBIA Policy.

                  (i) By noon, New York City time, on the Calculation Date, the
        Master Servicer shall confirm to the Trustee whether a Deficiency Amount
        will exist on the related Payment Date. If a Deficiency Amount will
        exist, the Master Servicer shall determine the amount of such
        Deficiency Amount and shall complete on behalf of the 


                                       61
<PAGE>   66

        Trustee a notice in the form of Exhibit A to the MBIA Policy (a
        "Notice") and submit such Notice to MBIA or its fiscal agent (with a
        copy to the Trustee), as set forth in the MBIA Policy not later than
        12:00 noon New York City time on the second Business Day preceding such
        Payment Date as a claim for an Insured Payment in an amount equal to
        such Deficiency Amount.

                  (ii) With respect to any Preference Amount (as defined in the
        MBIA Policy), MBIA shall pay any Insured Payment that is a Preference
        Amount on the Business Day (as defined in the MBIA Policy) following
        receipt on a Business Day by MBIA's fiscal agent of the items listed
        below. The Master Servicer, as agent of Trustee, shall provide to MBIA
        upon the request of MBIA:

                  (A) a certified copy of the final nonappealable order of a
                court having competent jurisdiction ordering the recovery by a
                trustee in bankruptcy as voidable preference amounts included in
                previous distributions under Section 2.03(b) of the Indenture to
                any Owner pursuant to the United States Bankruptcy Code.

                  (B) an opinion of counsel satisfactory to MBIA, and upon which
                MBIA shall be entitled to rely, stating that such order is final
                and is not subject to appeal;

                  (C) an assignment in such form as reasonably required by the
                Insurer, irrevocably assigning to MBIA all rights and claims of
                the Master Servicer, the Trustee and any Bondholder relating to
                or arising under the Transaction Documents against the debtor
                which made such preference payment or otherwise with respect to
                such preference amount; and

                  (D) appropriate instruments to effect (when executed by the
                affected party) the appointment of the Insurer as agent for the
                Trustee and any Owner in any legal proceeding relating to such
                preference payment being in a form satisfactory to MBIA.

                  (iii) The Master Servicer shall keep a complete and accurate
        record of the amount of interest and principal paid 


                                       62
<PAGE>   67

        in respect of any Bonds from moneys received under the MBIA Policy. MBIA
        shall have the right to inspect such records at reasonable times during
        normal business hours upon one Business Day's prior written notice to
        the Master Servicer.

        (p)    Optional Purchase of Pledged Mortgages

               The Master Servicer shall have the option to purchase all of the
remaining Pledged Mortgages on any Payment Date after the Payment Date with
respect to which the Pool Principal Balance is equal to 10% or less of the
Initial Pool Principal Balance at a price equal to the aggregate Purchase Price
of the Pledged Mortgages as of such Payment Date; provided, however, such option
shall be subject to the provisions of Section 10.01 of the Indenture.

4.      General Duties of the Servicers

               This Section 4 describes, in summary form, the Servicing
Agreements entered into among Redwood and the various Servicers who will service
the Pledged Mortgages. To the extent that any Servicing Agreement conflicts with
the summaries set forth in this Agreement, the provisions of the applicable
Servicing Agreement will govern. This section is for informational purposes only
and does not establish responsibilities and shall not be construed to impose any
obligations or duties on any Person, including, in particular, the Master
Servicer or any Servicer.

        (a)    Maintenance of Hazard Insurance; Maintenance of Primary
               Insurance Policies.

               (i) The Servicer shall cause to be maintained, in accordance with
        the terms and conditions of the related Servicing Agreement, for each
        Pledged Mortgage, hazard insurance with extended coverage in an amount
        that is at least equal to the lesser of (A) the maximum insurable value
        of the improvements securing such Pledged Mortgage or (B) the greater of
        (y) the outstanding principal balance of the Pledged Mortgage and (z) an
        amount such that the proceeds of such policy shall be sufficient to
        prevent the Mortgagor and/or the mortgagee from becoming a co-insurer.
        Each such policy of standard hazard insurance shall contain, or have 


                                       63
<PAGE>   68


        an accompanying endorsement that contains, a standard mortgagee clause.
        To the extent it may do so without breaching the related Servicing
        Agreement, the Master Servicer shall replace any Servicer that does not
        cause such insurance, to the extent it is available, to be maintained.
        Any amounts collected by the related Servicer under any such policies
        (other than the amounts to be applied to the restoration or repair of
        the related Mortgaged Property or amounts released to the Mortgagor in
        accordance with the Servicer's normal servicing procedures) shall be
        deposited in the Bond Account or the related Servicing Account, as
        applicable. Any cost incurred by any Servicer in maintaining any such
        insurance shall not, for the purpose of calculating payments to the
        Bondholders or remittances to the Trustee for their benefit, be added to
        the principal balance of the Pledged Mortgage, notwithstanding that the
        terms of the Pledged Mortgage so permit. Such costs shall be recoverable
        by the Servicer out of late payments by the related Mortgagor or out of
        Liquidation Proceeds to the extent permitted by Section 3(f). It is
        understood and agreed that no earthquake or other additional insurance
        is to be required of any Mortgagor or maintained on property acquired in
        respect of a Mortgage other than pursuant to such applicable laws and
        regulations as shall at any time be in force and as shall require such
        additional insurance. If the Mortgaged Property is located at the time
        of origination of the Pledged Mortgage in a federally designated special
        flood hazard area and such area is participating in the national flood
        insurance program, the related Servicer shall cause flood insurance to
        be maintained with respect to such Pledged Mortgage. Such flood
        insurance shall be in an amount equal to the least of (A) the original
        principal balance of the related Pledged Mortgage, (B) the replacement
        value of the improvements which are part of such Mortgaged Property, and
        (C) the maximum amount of such insurance available for the related
        Mortgaged Property under the national flood insurance program.

                      In the event that the Servicer shall obtain and maintain a
        blanket policy insuring against hazard losses on all of the Pledged
        Mortgages covered by the related Servicing Agreement, it shall
        conclusively be deemed to have satisfied its obligations as set forth in
        the first sentence 


                                       64
<PAGE>   69


        of this Section 4(a)(i), it being understood and agreed that such policy
        may contain a deductible clause on terms substantially equivalent to
        those commercially available and maintained by comparable servicers. If
        such policy contains a deductible clause, the Servicer shall, in the
        event that there shall not have been maintained on the related Mortgaged
        Property a policy complying with the first sentence of this Section
        4(a)(i), and there shall have been a loss that would have been covered
        by such policy, deposit in the Bond Account the amount not otherwise
        payable under the blanket policy because of such deductible clause. In
        connection with its activities as Servicer of Pledged Mortgages, each
        Servicer has agreed to present, on behalf of itself, the Issuer and the
        Trustee for the benefit of the Bondholders, claims under any such
        blanket policy.

               (ii) No Servicer shall take any action which would result in
        non-coverage under any applicable Primary Insurance Policy of any loss
        which, but for the actions of such Servicer, would have been covered
        thereunder. The Servicer shall not cancel or refuse to renew any such
        Primary Insurance Policy that is in effect at the date of the initial
        issuance of the Bonds and is required to be kept in force hereunder
        unless the replacement Primary Insurance Policy for such canceled or
        non-renewed policy is maintained with a Qualified Insurer. The related
        Servicer shall not be required to maintain any Primary Insurance Policy
        with respect to any Pledged Mortgage with a Loan-to-Value Ratio less
        than or equal to 80% as of any date of determination or, based on a new
        appraisal, the principal balance of such Pledged Mortgage represents 80%
        or less of the new Appraised Value. Each Servicer agrees to effect the
        timely payment of the premiums on each Primary Insurance Policy, and
        such costs not otherwise recoverable shall be recoverable by the related
        Servicer from the related liquidation proceeds.

                      In connection with its activities as Servicer of Pledged
        Mortgages, each Servicer agrees to present on behalf of itself, the
        Trustee and the Bondholders, claims to the insurer under any Primary
        Insurance Policies and, in this regard, to take such reasonable action
        as shall be necessary to permit recovery under any Primary Insurance
        Policies respecting defaulted Pledged Mortgages. Any amounts 


                                       65
<PAGE>   70


        collected by a Servicer under any Primary Insurance Policies shall be
        deposited in the Servicing Account, the Collection Account or the Bond
        Account, as applicable.

        (b)    Enforcement of Due-On-Sale Clauses; Assumption
               Agreements.

               (i) Except as otherwise provided in this Section 4(b), when any
        property subject to a Mortgage has been conveyed by the Mortgagor, the
        related Servicer shall, to the extent that it has knowledge of such
        conveyance, enforce any due-on-sale clause contained in any Mortgage
        Note or Mortgage, to the extent permitted under applicable law and
        governmental regulations, but only to the extent that such enforcement
        will not adversely affect or jeopardize coverage under any Required
        Insurance Policy. Notwithstanding the foregoing, the related Servicer is
        not required to exercise such rights with respect to a Pledged Mortgage
        if the Person to whom the related Mortgaged Property has been conveyed
        or is proposed to be conveyed satisfies the terms and conditions
        contained in the Mortgage Note and Mortgage related thereto and the
        consent of the mortgagee under such Mortgage Note or Mortgage is not
        otherwise so required under such Mortgage Note or Mortgage as a
        condition to such transfer. In the event that (A) the related Servicer
        is prohibited by law from enforcing any such due-on-sale clause, (B)
        coverage under any Required Insurance Policy would be adversely
        affected, (C) the Mortgage Note does not include a due-on-sale clause or
        permits assumptions of the Mortgage Note subject to certain conditions,
        or (D) nonenforcement is otherwise permitted hereunder, the Servicer is
        authorized by the related Servicing Agreement, subject to certain
        provisions of the related Servicing Agreement, to take or enter into an
        assumption and modification agreement from or with the person to whom
        such property has been or is about to be conveyed, pursuant to which
        such person becomes liable under the Mortgage Note and, unless
        prohibited by applicable state law, the Mortgagor remains liable
        thereon, provided that the Pledged Mortgage shall continue to be covered
        (if so covered before the Servicer enters such agreement) by the
        applicable Required Insurance Policies. The Servicer, subject to certain
        provisions of the related Servicing Agreement, is 


                                       66
<PAGE>   71


        also authorized by the related Servicing Agreement with the prior
        approval of the insurers under any Required Insurance Policies to enter
        into a substitution of liability agreement with such Person, pursuant to
        which the original Mortgagor is released from liability and such Person
        is substituted as Mortgagor and becomes liable under the Mortgage Note.
        Notwithstanding the foregoing, the Servicer shall not be deemed to be in
        default under the applicable Section of the related Servicing Agreement
        by reason of any transfer or assumption which the Servicer reasonably
        believes it is restricted by law from preventing, for any reason
        whatsoever.

               (ii) Subject to the Servicer's duty to enforce any due-on-sale
        clause as described above, in any case in which a Mortgaged Property has
        been conveyed to a Person by a Mortgagor, and such Person is to enter
        into an assumption agreement or modification agreement or supplement to
        the Mortgage Note or Mortgage that requires the signature of the
        Trustee, or if an instrument of release signed by the Trustee is
        required releasing the Mortgagor from liability on the Pledged Mortgage,
        the Servicer shall prepare and deliver or cause to be prepared and
        delivered to the Trustee for signature and shall direct, in writing, the
        Trustee to execute the assumption agreement with the Person to whom the
        Mortgaged Property is to be conveyed and such modification agreement or
        supplement to the Mortgage Note or Mortgage or other instruments as are
        reasonable or necessary to carry out the terms of the Mortgage Note or
        Mortgage or otherwise to comply with any applicable laws regarding
        assumptions or the transfer of the Mortgaged Property to such Person. In
        connection with any such assumption, no material term of the Mortgage
        Note may be changed. In addition, the substitute Mortgagor and the
        Mortgaged Property must be acceptable to the Servicer in accordance with
        its underwriting standards as then in effect. Together with each such
        substitution, assumption or other agreement or instrument delivered to
        the Trustee for execution by it, the Servicer shall deliver an Officer's
        Certificate signed by a servicing officer of the Servicer stating that
        the requirements described in this subsection have been met in
        connection therewith. The Servicer shall notify the Trustee that any
        such substitution or assumption agreement has been completed by
        forwarding to


                                       67
<PAGE>   72


        the Trustee the original of such substitution or assumption agreement,
        which in the case of the original shall be forwarded to the Custodian
        and added to the related Trustee Mortgage File and shall, for all
        purposes, be considered a part of such Trustee Mortgage File to the same
        extent as all other documents and instruments constituting a part
        thereof. Any fee collected by any Servicer for entering into an
        assumption or substitution of liability agreement will be retained by
        the Servicer as additional servicing compensation.

        (c)    Realization Upon Defaulted Pledged Mortgages; Purchase
               of Certain Pledged Mortgages.

               Each Servicer shall use reasonable efforts to foreclose upon or
otherwise comparably convert the ownership of properties securing such of the
Pledged Mortgages as come into and continue in default and as to which no
satisfactory arrangements can be made for collection of delinquent payments. In
connection with such foreclosure or other conversion, each Servicer shall follow
such practices and procedures as it shall deem necessary or advisable, as shall
be normal and usual in its general mortgage servicing activities and as shall
meet the requirements of the insurer under any Required Insurance Policy.
Notwithstanding the foregoing, no Servicer shall be required to expend its own
funds in connection with any foreclosure or towards the restoration of any
property unless it shall determine (A) that such restoration and/or foreclosure
will increase the proceeds of liquidation of the Pledged Mortgage after
reimbursement to itself of such expenses and (B) that such expenses will be
recoverable to it through Liquidation Proceeds (respecting which it shall have
priority for purposes of withdrawals from the Bond Account). Each Servicer shall
be responsible for all other costs and expenses incurred by it in any such
proceedings; provided, however, that it shall be entitled to reimbursement
thereof from the liquidation proceeds with respect to the related Mortgaged
Property, as provided in the definition of Liquidation Proceeds. If a Servicer
has knowledge that a Mortgaged Property which the Servicer is contemplating
acquiring in foreclosure or by deed in lieu of foreclosure is located within a 1
mile radius of any site listed in the Expenditure Plan for the Hazardous
Substance Clean Up Bond Act of 1984 or other site with environmental or
hazardous waste risks known to the Servicer, that Servicer will, prior to


                                       68
<PAGE>   73


acquiring the Mortgaged Property, consider such risks and only take action in
accordance with its established environmental review procedures.

               With respect to any REO Property, the deed or certificate of sale
shall be taken in the name of the Trustee for the benefit of the Bondholders, or
its nominee, on behalf of the Bondholders. The Trustee's name shall be placed on
the title to such REO Property solely as the Trustee under the Indenture and not
in its individual capacity. The related Servicer shall ensure that the title to
such REO Property references the Indenture and the Trustee's capacity
thereunder. Pursuant to its efforts to sell such REO Property, the related
Servicer shall either itself or through an agent selected by the related
Servicer protect and conserve such REO Property in the same manner and to such
extent as is customary in the locality where such REO Property is located and
may, incident to its conservation and protection of the interests of the
Bondholders, rent the same, or any part thereof, as the related Servicer deems
to be in the best interest of the Bondholders for the period prior to the sale
of such REO Property. The net monthly rental income, if any, from such REO
Property shall be deposited in the Bond Account no later than the close of
business on each Determination Date. The related Servicer shall perform the tax
reporting and withholding required by Sections 1445 and 6050J of the Code with
respect to foreclosures and abandonments, the tax reporting required by Section
6050H of the Code with respect to the receipt of mortgage interest from
individuals and, if required by Section 6050P of the Code with respect to the
cancellation of indebtedness by certain financial entities, by preparing such
tax and information returns as may be required, in the form required, and
delivering the same to the Trustee for filing.

               The decision of a Servicer to foreclose on a defaulted Pledged
Mortgage shall be subject to a determination by such Servicer that the proceeds
of such foreclosure would exceed the costs and expenses of bringing such a
proceeding. The income earned from the management of any REO Properties, net of
reimbursement to the Servicer for expenses incurred (including any property or
other taxes) in connection with such management and net of unreimbursed
Servicing Fees, Advances and Servicing Advances, shall be applied to the payment
of principal of and interest on the related defaulted Pledged Mortgages (with


                                       69
<PAGE>   74


interest accruing as though such Pledged Mortgages were still current and
adjustments, if applicable, to the Mortgage Rate were being made in accordance
with the terms of the Mortgage Note) and all such income shall be deemed, for
all purposes in this Agreement, to be payments on account of principal and
interest on the related Mortgage Notes and shall be deposited into the Bond
Account. To the extent the net income received during any calendar month is in
excess of the amount attributable to amortizing principal and accrued interest
at the related Mortgage Rate on the related Pledged Mortgage for such calendar
month, such excess shall be considered to be a partial prepayment of principal
of the related Pledged Mortgage.

               The proceeds from any liquidation of a Pledged Mortgage, as well
as any income from an REO Property, will be applied in the following order of
priority: first, to reimburse the related Servicer for any related unreimbursed
Advances or Servicing Advances and Servicing Fees, as applicable; second, to
reimburse the related Servicer for any unreimbursed Servicer Advances, as
applicable, and to reimburse the Bond Account for any Nonrecoverable Advances
(or portions thereof) that were previously withdrawn by the Master Servicer
pursuant to Section 3(f) that related to such Pledged Mortgage; third, to
accrued and unpaid interest (to the extent no Advance or Servicer Advance has
been made for such amount or any such Advance or Servicer Advance has been
reimbursed) on the Pledged Mortgage or related REO Property at the Net Mortgage
Rate to the Due Date occurring in the month in which such amounts are required
to be distributed; and fourth, as a recovery of principal of the Pledged
Mortgage. Excess Proceeds, if any, from the liquidation of a Liquidated Pledged
Mortgage will be retained by the Servicer as additional servicing compensation
pursuant to the terms of the related Servicing Agreement.

               Each Servicer, in its sole discretion, shall have the right to
purchase for its own account from the Issuer any Pledged Mortgage which is 91
days or more delinquent at a price equal to the Purchase Price. The Purchase
Price for any Pledged Mortgage purchased hereunder shall be deposited in the
Bond Account and the Trustee, upon receipt of a Request for Release, shall cause
to be released to the purchaser 


                                       70
<PAGE>   75


of such Pledged Mortgage the related Trustee Mortgage File and shall execute and
deliver such instruments of transfer or assignment prepared by the purchaser of
such Pledged Mortgage, in each case without recourse, as shall be necessary to
vest in the purchaser of such Pledged Mortgage any Pledged Mortgage released
pursuant hereto and the purchaser of such Pledged Mortgage shall succeed to all
the Issuer's and the Trustee's right, title and interest in and to such Pledged
Mortgage and all security and documents related thereto. Such assignment shall
be an assignment outright and not for security. The purchaser of such Pledged
Mortgage shall thereupon own such Pledged Mortgage, and all security and
documents, free of any further obligation to the Issuer, the Trustee or the
Bondholders with respect thereto.

        (d)    Collection of Taxes, Assessments and Similar Items;
               Escrow Accounts.

               (i) To the extent required by the related Mortgage Note and not
        violative of current law, each Servicer shall, in accordance with the
        terms of the related Servicing Agreement establish and maintain one or
        more accounts (each, an "Escrow Account") and deposit and retain therein
        all collections from the Mortgagors (or advances by the Servicer) for
        the payment of taxes, assessments, hazard insurance premiums or
        comparable items for the account of the Mortgagors. Nothing herein shall
        require any Servicer to compel a Mortgagor to establish an Escrow
        Account in violation of applicable law.

               (ii) Withdrawals of amounts so collected from the Escrow Accounts
        may be made only to effect timely payment of taxes, assessments, hazard
        insurance premiums, condominium or PUD association dues, or comparable
        items, to reimburse the related Servicer out of related collections for
        any payments made pursuant to Sections 4(d) (with respect to taxes and
        assessments and insurance premiums) and 4(a) (with respect to hazard
        insurance), to refund to any Mortgagors any sums determined to be
        overages, to pay interest, if required by law or the terms of the
        related Mortgage or Mortgage Note, to Mortgagors on balances in the
        Escrow Account or to clear and terminate the Escrow Account at the
        termination of this Agreement in accordance with Section 9(a). The
        Escrow Accounts shall not be a part of the Trust Estate.


                                       71

        (e)    Documents, Records and Funds in Possession of Servicer
               to be Held for Trustee.

               The related Servicer shall deliver all documents and instruments
relating to the Pledged Mortgages coming into the possession of the related
Servicer from time to time and shall account fully to the Trustee for any funds
received by the Servicer or which otherwise are collected by the Servicer as
Liquidation Proceeds or Insurance Proceeds in respect of any Pledged Mortgage.
All Trustee Mortgage Files, including without limitation the Mortgage Documents
contained therein, funds collected or held by, or under the control of, the
Servicer from time to time in respect of any Pledged Mortgages, whether from the
collection of principal and interest payments or from Liquidation Proceeds or
Insurance Proceeds, including but not limited to any funds on deposit in any
Eligible Account and any other items constituting a part of the Trust Estate
which from time to time come into the possession of the Servicer, shall be held
by the Servicer for and on behalf of the Trustee and the Bondholders and MBIA as
specified in Section 8.10 of the Indenture, and shall be and remain the sole and
exclusive property of the Trustee, subject to the applicable provisions of this
Agreement and the Indenture.

        (f)    Annual Independent Public Accountants' Servicing
               Statement; Financial Statements.

               Pursuant to the Servicing Agreements, on or before 120 days after
the end of each Servicer's fiscal year, commencing with its 1997 fiscal year,
each Servicer at its expense shall cause a nationally recognized firm of
independent public accountants (who may also render other services to a Servicer
or any affiliate thereof) which is a member of the American Institute of
Certified Public Accountants to furnish a statement to the Master Servicer to
the effect that such firm has examined certain documents and records relating to
the servicing of Pledged Mortgages under the related Servicing Agreement or of
mortgage loans under servicing agreements substantially similar to the related
Servicing Agreement (such statement to have attached thereto a schedule setting
forth the servicing agreements covered thereby) and that, on the basis of such
examination, conducted substantially in compliance with the Uniform Single
Attestation Program for Mortgage Bankers or the 


                                       72
<PAGE>   77


Audit Program for Mortgages serviced for FNMA and FHLMC, such servicing has been
conducted in compliance with such servicing agreements except for such
significant exceptions or errors in records that, in the opinion of such firm,
the Uniform Single Attestation Program for Mortgage Bankers or the Audit Program
for Mortgages serviced for FNMA and FHLMC requires it to report. Copies of such
statement shall be provided by each Servicer to the Master Servicer who will,
(1) in turn provide such statements to the Trustee, the Issuer and MBIA and (2)
notify the Trustee, the Issuer and MBIA of the failure of any Servicer to
provide such statements as required under the applicable Servicing Agreement.

5.      Advances.

               The Master Servicer shall determine on or before each Master
Servicer Advance Date whether any Servicer has failed to make any Advance of any
Scheduled Payment of principal and interest required to be made by such Servicer
pursuant to the terms of its Servicing Agreement. If the Master Servicer
determines that any such Servicer has failed to make any such required Advance
the Master Servicer shall make such Advance (a "Master Servicer Advance") on or
before the Master Servicer Advance Date, by either (i) depositing into the
Distribution Account an amount equal to the Master Servicer Advance or (ii)
making an appropriate entry in its records relating to the Distribution Account
that any Amount Held for Future Distribution has been used by the Master
Servicer in discharge of its obligation to make any such Master Servicer Advance
(any funds so applied shall be replaced by the Master Servicer by deposit in the
Distribution Account no later than the close of business on the next Master
Servicer Advance Date); provided, however, in no event shall the Master Servicer
be required to make any Master Servicer Advance that the Master Servicer
determines would constitute a Nonrecoverable Advance. The Master Servicer shall
be entitled to be reimbursed from the Bond Account for all Master Servicer
Advances of its own funds made pursuant to this Section 5 as provided in Section
3(f)(iii). The Master Servicer shall inform the Trustee of the amount of the
Advance to be made on each Master Servicer Advance Date no later than the second
Business Day before the related Payment Date.


                                       73
<PAGE>   78


               The Master Servicer shall deliver to the Trustee on the related
Master Servicer Advance Date an Officer's Certificate of a Servicing Officer
indicating the amount of any proposed Master
Servicer Advance determined by the Master Servicer to be a Nonrecoverable
Advance.

6.      Master Servicing Compensation and Expenses.

        (a)    Master Servicer Compensation.

               As compensation for its activities hereunder, the Master Servicer
shall be entitled to the Master Servicing Fee which shall equal the investment
earnings (net of any losses) on the moneys deposited in the Distribution
Account. On or prior to each Payment Date, the Master Servicer shall be entitled
to withdraw the related Master Servicing Fee from the Distribution Account.

               The Master Servicer shall be required to pay all expenses
incurred by it in connection with its master servicing activities hereunder and
shall not be entitled to reimbursement therefor except as specifically provided
in this Agreement.

        (b)    Servicer Compensation.

               As compensation for its activities under its Servicing Agreement,
each Servicer shall be entitled to retain out of each payment of interest on a
Pledged Mortgage (or portion thereof) an amount equal to interest at the
applicable Servicing Fee Rate on the Stated Principal Balance of the related
Pledged Mortgage for the period covered by such interest payment as provided in
the related Servicing Agreement.

               Additional servicing compensation in the form of pre-payment
penalties, assumption fees and late payment charges shall be retained by the
Servicers if and to the extent provided in the related Servicing Agreement. Each
Servicer shall be required to pay all expenses incurred by it in connection with
its servicing activities under its Servicing Agreement (including payment of any
premium for hazard insurance and any Primary Insurance Policy and maintenance of
the other forms of insurance coverage required by this Agreement and its
Servicing Agreement) and shall not be entitled to reimbursement therefor except
as specifically pro-


                                       74

vided in its Servicing Agreement and not inconsistent with this Agreement.

7.      Master Servicer.

        (a)    Liabilities of the Master Servicer.

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

        (b)    Merger or Consolidation of the Master Servicer.

               Any Person into which the Master Servicer may be merged or
consolidated, or any Person resulting from any merger or consolidation to which
the Master Servicer shall be a party, or any person succeeding to the business
of the Master Servicer, shall be the successor of the Master Servicer hereunder,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto, anything herein to the contrary notwithstanding;
provided, however, that the successor or surviving Person to the Master Servicer
shall be qualified to perform the obligations of the Master Servicer under this
Agreement and, so long as no MBIA default has occurred and is continuing, be
reasonably acceptable to MBIA.

        (c)    Limitation on Liability of the Master Servicer and
               Others.

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


                                       75
<PAGE>   80


        Master Servicer and any director, officer, employee or agent of the
        Master Servicer may rely in good faith on any document of any kind prima
        facie properly executed and submitted by any Person respecting any
        matters arising hereunder. The Master Servicer and any director,
        officer, employee or agent of the Master Servicer shall be indemnified
        by the Issuer and held harmless against any loss, liability or expense
        incurred in connection with any audit, controversy or judicial
        proceeding relating to a governmental taxing authority or any legal
        action relating to this Agreement or the Bonds, other than any loss,
        liability or expense related to any specific Pledged Mortgage or Pledged
        Mortgages (except as any such loss, liability or expense shall be
        otherwise reimbursable pursuant to this Agreement) and any loss,
        liability or expense incurred by reason of the Master Servicer's willful
        misfeasance, bad faith or negligence in the performance of its duties
        hereunder or by reason of reckless disregard of its obligations and
        duties hereunder. The Master Servicer shall not be under any obligation
        to appear in, prosecute or defend any legal action that is not
        incidental to its respective duties hereunder and which in its opinion
        may involve it in any expense or liability; provided, however, that the
        Master Servicer may in its discretion undertake any such action that it
        may deem necessary or desirable in respect of this Agreement and the
        rights and duties of the parties hereto and interests of the Issuer, the
        Trustee and the Bondholders 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 Issuer, and the Master Servicer
        shall be entitled to be reimbursed therefor out of the Bond Account;
        provided, however, that unless a MBIA Default exists, the Master
        Servicer shall notify MBIA of such legal action (provided that the
        failure to notify MBIA shall not waive the rights of the Master Servicer
        to indemnification) and such indemnification by the Issuer out of the
        Bond Account shall be preconditioned on the Master Servicer's duty (i)
        to allow MBIA to control the defense or settlement of any such action
        and (ii) to allow MBIA to direct the Master Servicer with respect
        thereto; provided, further, that (a) if MBIA does not assume control of
        the defense of any such action within a reasonable period of time after
        the filing of such action, 


                                       76
<PAGE>   81


        the Master Servicer shall have the right to act on its own in defending
        the action until such time as MBIA assumes control of the defense, (b)
        the Master Servicer along with MBIA shall have the right to consent to
        any counsel hired to defend the Master Servicer (which consent of the
        Master Servicer shall not be unreasonably withheld) and (c) the Master
        Servicer along with MBIA shall have the right to consent to any
        settlement if the amount of such settlement is less than full
        indemnification and the Master Servicer would not be fully released from
        liability with respect to such action as a result of such settlement.
        Any amounts payable to the Master Servicer, or any director, officer,
        employee or agent of the Master Servicer, in respect of indemnification
        provided by this paragraph (c)(i), or pursuant to any other right of
        reimbursement from the Bond Account that the Master Servicer, or any
        director, officer, employee or agent of the Master Servicer, may have
        hereunder in its capacity as such, may be withdrawn by the Master
        Servicer from the Bond Account at any time subject to a maximum amount
        of $150,000 in any calendar year pursuant to Section 3(b)(ii) and
        Section 3(f)(iii)(D) of this Agreement. Any such amounts due to the
        Master Servicer, or any director, officer, employee or agent of the
        Master Servicer, in excess of $150,000 in such calendar year shall be
        reimbursable pursuant to Section 3(f)(vii)(G).

               (ii) With respect to legal prosecution of a claim by the Master
        Servicer against a Servicer pursuant to Section 3(b)(ii) hereof, unless
        a MBIA Default has occurred and is continuing, the Master Servicer shall
        notify MBIA of such legal action and such indemnification by the Issuer
        out of the Bond Account shall be preconditioned on the Master Servicer's
        duty (i) to allow MBIA to control the prosecution and settlement of any
        such claim and (ii) to allow MBIA to direct the Master Servicer with
        respect thereto; provided further, that (a) if MBIA does not assume
        control of the prosecution of any such claim within a reasonable period
        of time after the filing of such claim, the Master Servicer shall have
        the right to act on its own in prosecuting the claim until such time as
        MBIA assumes control of the prosecution, (b) the Master Servicer along
        with MBIA shall have the right to consent to any counsel hired by the
        Master Servicer to prosecute such claim (which consent of 


                                       77
<PAGE>   82


        the Master Servicer shall not be unreasonably withheld) and (c) the
        Master Servicer along with MBIA shall have the right to consent to any
        settlement if the amount of such settlement is less than an amount
        sufficient to cover all amounts due in respect of the related Pledged
        Mortgage and the amounts advanced by the Master Servicer in connection
        with such claim. Any amounts payable to the Master Servicer or any
        director, officer, employee or agent of the Master Servicer, in respect
        of indemnification provided by this paragraph (c)(ii), or pursuant to
        any right of reimbursement from the Bond Account that the Master
        Servicer, or any director, officer, employee or agent of the Master
        Servicer may have hereunder in its capacity as such, may be withdrawn by
        the Master Servicer from the Bond Account at any time, subject to a
        maximum amount of $150,000 in any calendar year pursuant to Section
        3(b)(ii) and Section 3(f)(iii)(D) of this Agreement. Any such amount due
        the Master Servicer, or any director officer, employee or agent of the
        Master Servicer in excess of $150,000 in such calendar year shall be
        reimbursable pursuant to Section 3(f)(vii)(G) of this Agreement.

        (d)    Limitation on Resignation of the Master Servicer.

               The Master Servicer shall not resign from the obligations and
duties hereby imposed on it except (a) upon appointment of a successor master
servicer reasonably acceptable to MBIA and receipt by the Trustee of a letter
from each Rating Agency that such a resignation and appointment will not result
in a downgrading of the rating of any of the Bonds (without regard to the MBIA
Policy) and with the prior written consent of MBIA, which consent will not be
unreasonably withheld or (b) upon determination that its duties hereunder are no
longer permissible under applicable law. Any such determination under clause (b)
permitting the resignation of the Master Servicer shall be evidenced by an
Opinion of Counsel at the expense of the Master Servicer to such effect
delivered to the Trustee and the Insurer which opinion of counsel shall be
reasonably acceptable to the Trustee and MBIA. No such resignation shall become
effective until the Trustee or a successor master servicer reasonably acceptable
to MBIA shall have assumed the Master Servicer's responsibilities, duties,
liabilities and obligations hereunder.

        (a)    Master Servicing Default.

               Any of the following acts or occurrences shall constitute a

        date of such failure.

               If a Master Servicing Default described in clauses (i) to (v) of
this Section 8(a) shall occur, then, and in each and every such case, so long as
such Master Servicing Default shall not have been remedied the Trustee may, with
the prior written consent of MBIA, and shall at the direction of MBIA (subject
to Section 3.07 and Section 8.11 of the Indenture), by notice in writing to the
Master Servicer (with a copy to each Rating Agency and MBIA), and in addition to
any other rights the Trustee may have on behalf of the Bondholders or MBIA as a
result of such Master Servicing Default, terminate all of the rights and
obligations of the Master Servicer thereafter arising under this Agreement and
in and to the Pledged Mortgages and the proceeds thereof, other than its rights
as a Bondholder under the Indenture and its obligations which are not assumed by
the Trustee pursuant to clauses (i), (iii) and (v) of Section 3(f). If a Master
Servicing Default described in clause (vi) shall occur, the Trustee shall, by
notice in writing to the Master Servicer and the Issuer, terminate all of the
rights and obligations of the Master Servicer under this Agreement and in and to
the Pledged Mortgages and the proceeds thereof, other than 


                                       80
<PAGE>   85


its rights as a Bondholder under the Indenture and its obligations which are not
assumed by the Trustee pursuant to clauses (i), (iii) and (v) of Section 3(f).
On and after the receipt by the Master Servicer of such written notice, all
authority and power of the Master Servicer hereunder, whether with respect to
the Pledged Mortgages or otherwise, unless an alternative successor Master
Servicer reasonably acceptable to MBIA shall have been appointed, shall pass to
and be vested in the Trustee. The Trustee shall thereupon make any Advance
described in clause (vi) subject to clause (ii) of the first sentence of Section
3(f). The Trustee is hereby authorized and empowered to execute and deliver, on
behalf of the Master Servicer, as attorney-in-fact or otherwise, any and all
documents and other instruments, and to do or accomplish all other acts or
things necessary or appropriate to effect the purposes of such notice of
termination, whether to complete the transfer and endorsement or assignment of
the Pledged Mortgages and related documents, or otherwise. The Master Servicer
agrees to cooperate with the Trustee in effecting the termination of the Master
Servicer's responsibilities and rights hereunder, including, without limitation,
the transfer to the Trustee of all cash amounts which shall at the time be
credited to the Bond Account or thereafter be received by the Master Servicer
with respect to the Pledged Mortgages.

               Notwithstanding any termination of the activities of the Master
Servicer hereunder, the Master Servicer shall be entitled to receive, out of any
late collection of a Scheduled Payment on a Pledged Mortgage which was due prior
to the notice terminating such Master Servicer's rights and obligations as
Master Servicer hereunder and received after such notice, that portion thereof
to which such Master Servicer would have been entitled pursuant to Section
3(f)(iii)(A), (B) or (D) or 3(f)(vii)(G), and any other amounts payable to such
Master Servicer hereunder the entitlement to which arose prior to the
termination of its activities hereunder.

        (b)    Trustee to Act; Appointment of Successor.

               On and after the time the Master Servicer receives a notice of
termination pursuant to Section 7(a), the Trustee shall, subject to and to the
extent provided in Section 3(f), unless an alternative Master Servicer
reasonably acceptable to 


                                       81
<PAGE>   86


MBIA has been appointed, be the successor to the Master Servicer in its capacity
as master servicer under this Agreement and the transactions set forth or
provided for herein and shall be subject to all the responsibilities, duties and
liabilities relating thereto placed on the Master Servicer by the terms and
provisions hereof and applicable law including the obligation to make Advances
pursuant to Section 5. As compensation therefor, the Trustee shall be entitled
to all funds relating to the Pledged Mortgages that the Master Servicer would
have been entitled to charge to the Bond Account or Distribution Account if the
Master Servicer had continued to act hereunder. Notwithstanding the foregoing,
if the Trustee has become the successor to the Master Servicer in accordance
with Section 8(a), the Trustee may, if it shall be unwilling to so act, or
shall, if it is prohibited by applicable law from making Advances pursuant to
Section 5 or if it is otherwise unable to so act, appoint, or petition a court
of competent jurisdiction to appoint, any established mortgage loan servicing
institution acceptable to MBIA the appointment of which does not adversely
affect the then current rating of the Bonds (without regard to the existence of
the MBIA Policy) by each Rating Agency as the successor to the Master Servicer
hereunder in the assumption of all or any part of the responsibilities, duties
or liabilities of the Master Servicer hereunder. Any successor to the Master
Servicer shall be an institution which is a FNMA and FHLMC approved
seller/servicer in good standing, which has a net worth of at least $15,000,000,
which is willing to master service the Pledged Mortgages and which executes and
delivers to the Issuer, MBIA and the Trustee an agreement accepting such
delegation and assignment, containing an assumption by such Person of the
rights, powers, duties, responsibilities, obligations and liabilities of the
Master Servicer (other than liabilities of the Master Servicer under Section
7(c) incurred prior to termination of the Master Servicer under Section 8(a)),
with like effect as if originally named as a party to this Agreement; provided
that each Rating Agency acknowledges that its rating of the Bonds (without
regard to the existence of the MBIA Policy) in effect immediately prior to such
assignment and delegation will not be qualified or reduced as a result of such
assignment and delegation. Pending appointment of a successor to the Master
Servicer hereunder, the Trustee, unless the Trustee is prohibited by law from so
acting, shall, subject to Section 3(f), act in such capacity as hereinabove
provided. In connection with such 


                                       82
<PAGE>   87


appointment and assumption, the Trustee may make such arrangements for the
compensation of such successor out of earnings on the accounts as it and such
successor and MBIA shall agree; provided, however, that no such compensation
shall be in excess of the Master Servicing Fee permitted the Master Servicer
hereunder. The Trustee and such successor shall take such action, consistent
with this Agreement, as shall be necessary to effectuate any such succession.
Neither the Trustee nor any other successor master servicer shall be deemed to
be in default hereunder by reason of any failure to make, or any delay in
making, any distribution hereunder or any portion thereof or any failure to
perform, or any delay in performing, any duties or responsibilities hereunder,
in either case caused by the failure of the preceding Master Servicer to deliver
or provide, or any delay in delivering or providing, any cash, information,
documents or records to it.

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

        (c)    Notification to Bondholders.

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

               (ii) Within 60 days after the occurrence of any Master Servicing
        Default, the Trustee shall transmit by mail to all
        Bondholders and the Issuer notice of each such Master Servicing Default
        hereunder known to the Trustee, unless such Master Servicing Default
        shall have been cured or waived.

9.      Miscellaneous.

        (a)    Term of Master Servicing Agreement.

               The obligations to be performed by the Master Servicer under this
Agreement shall commence on and as of the date on 


                                       83
<PAGE>   88


which the Issuer issues the Bonds and shall terminate as to each Pledged
Mortgage upon (i) the payment in full of all principal and interest due under
such Pledged Mortgage or other liquidation of such Pledged Mortgage as
contemplated by this Agreement, (ii) the termination of the Master Servicer's
rights and powers under this Agreement by the Trustee as provided in Section
8(a) of this Agreement, or (iii) the release by the Trustee of its security
interest in such Pledged Mortgage.

        (b)    Assignment.

               Notwithstanding anything to the contrary contained herein, except
as provided in Section 6(b), this Agreement may not be assigned by the Master
Servicer without the prior written consent of the Trustee and MBIA and written
notice to the Issuer.

        (c)    Notices.

               The Master Servicer agrees that, on reasonable prior notice, it

records, reports and other papers of the Master Servicer relating to the Pledged
Mortgages, to make copies and extracts therefrom, to cause such books to be
audited by independent certified public accountants selected by the Trustee or
MBIA and to discuss its affairs, finances and accounts relating to the Pledged
Mortgages with its officers, employees and independent public accountants (and
by this provision the Master Servicer hereby authorizes said accountants to
discuss with such representative such affairs, finances and accounts), all at
such reasonable times and as often as may be reasonably requested. Any
out-of-pocket expense incident to the exercise by the Issuer, MBIA or the
Trustee of any right under this Section 8(d) shall be borne by the party
requesting such inspection.

        (e)    Governing Law.

the Target Percentage and the Serious Delinquencies, may be made solely upon (i)
the written consent of the Issuer and MBIA and (ii) an opinion of tax counsel to
the Issuer, without regard to Section 8.09 of the Indenture.

        (g)    Severability.

               If any one or more of the covenants, agreements, provisions or
terms of this Agreement shall be for any reason whatsoever held invalid, then
such covenants, agreements, provisions or terms shall be deemed severable from
the remaining covenants, agreements, provisions or terms of this Agreement and
shall in no way affect the validity or enforceability of the other provisions of
this Agreement.

        (h)    No Joint Venture.

               The Master Servicer and the Issuer are not partners or joint

them.

        (i)    Execution in Counterparts.

               This Agreement may be executed in one or more counterparts, any
of which shall constitute an original as against any party whose signature

               It is expressly understood and agreed by the parties hereto that

1 under the Deposit Trust Agreement, in the exercise of the powers and authority
conferred and vested in it as Owner Trustee, (b) each of the representations,
undertakings and agreements herein made on the part of the Issuer is made and
intended not as personal representations, undertakings and agreements by
Wilmington Trust Company but is made and intended for the purpose for binding
only the Issuer, (c) nothing herein contained shall be construed as creating any
liability on Wilmington Trust Company, and (d) under no circumstances shall
Wilmington Trust Company be personally liable for the payment of any
indebtedness or expenses of the Issuer or be liable for the breach or failure of

acquiesce, petition or otherwise invoke or cause the Issuer (or any assignee) to

bankruptcy, insolvency or similar law, or appointing a receiver, liquidator,
assignee, trustee, custodian, sequestrator or other similar official of the
Issuer or any substantial part of its property, or ordering the winding up or

                          Collateralized Mortgage Bonds

              Representations and Warranties of the Master Servicer


               Norwest Bank Minnesota, N.A. ("Norwest") hereby makes the
representations and warranties set forth in this Schedule II to the Issuer, MBIA
and the Trustee, as of the Closing Date. Capitalized terms used but not
otherwise defined in this Schedule II shall have the meanings ascribed thereto
in the Master Servicing Agreement (the "Master Servicing Agreement") relating to
the above-referenced Series, among Norwest, as Master Servicer, Sequoia Mortgage
Trust 1, as Issuer, and First Union National Bank, as Trustee.

        execution and delivery thereof by the other parties thereto, constitutes
        a legal, valid and binding obligation of Norwest, enforceable against
        Norwest in accordance with its terms, except that (a) the enforceability
        thereof may be limited by bankruptcy, insolvency, moratorium,
        receivership and other similar laws relating to creditors' rights
        generally and (b) the remedy of specific performance and injunctive and
        other forms of equitable relief may be subject to equitable defenses and

                      (3) The execution and delivery of the Master Servicing
        Agreement by Norwest, the master servicing of the Pledged Mortgages by
        Norwest under the Master Servicing Agreement, the consummation of any
        other of the transactions contemplated by the Master Servicing
        Agreement, and the fulfillment of or compliance with the terms thereof
        will not (A) result in a material breach of any term or provision of the
        charter or by-laws of Norwest or (B) materially conflict with, result in
        a material breach, violation or acceleration of, or result in a material
        default under, the terms of any other material agreement or instrument
        to which Norwest is a party or by which it may be bound, or (C)
        constitute a material violation of any statute, order or regulation

                      (4) No litigation is pending or, to the best of Norwest's

                                  SCHEDULE III

                            SEQUOIA MORTGAGE TRUST 1
                          Collateralized Mortgage Bonds

           Representations and Warranties as to the Pledged Mortgages


               In the Mortgage Loan Purchase Agreement (which is hereby assigned
to the Trustee), Redwood (the "Seller") will make the representations and
warranties set forth in this Schedule III, as of the Closing Date, or if so
specified herein, as of the Cut-off Date. Capitalized terms used but not
otherwise defined in this Schedule III shall have the meanings ascribed thereto
in the Master Servicing Agreement (the "Master Servicing Agreement") relating to
the above-referenced Series of Bonds, issued by Sequoia Mortgage Trust 1.

                      (1) The information set forth on Schedule I to the Master
        Servicing Agreement with respect to each Pledged Mortgage and the
        computer tape describing the Pledged Mortgages delivered to the Insurer
        prior to closing are true and correct in all material respects as of the
        Closing Date.

                      (2) The Pledged Mortgages, individually and in the
        aggregate, conform in all material respects to the descriptions thereof
        in the Prospectus Supplement. The Pledged Mortgages are not being
        transferred with any intent to hinder, delay or defraud any creditors.

                      (3) With respect to any Pledged Mortgage that is not a
        Cooperative Loan, each Mortgage is a valid and enforceable first lien on
        the Mortgaged Property subject only to (a) the lien of non-delinquent
        current real property taxes and assessments, (b) covenants, conditions
        and restrictions, rights of way, easements and other matters of public
        record as of the date of recording of such Mortgage, such exceptions
        appearing of record being acceptable to mortgage lending institutions
        generally or specifically reflected in the appraisal made in connection
        with the origination of the related Pledged Mortgage, and (c) other
        matters to which like properties are commonly subject which


                                     S-III-1

<PAGE>   99
        do not materially interfere with the benefits of the security intended
        to be provided by such Mortgage.

                      (4) Immediately prior to sale to the Company and the
        Issuer for pledge to the Trustee for the benefit of the Bondholders, the
        Seller had good title to, and was the sole owner of, each Pledged
        Mortgage free and clear of any pledge, lien, encumbrance or security
        interest and had full right and authority, subject to no interest or
        participation of, or agreement with, any other party, to pledge and
        assign the same pursuant to the Indenture. Immediately after the sale by
        the Company to the Issuer, the Issuer had good title to, and was the
        sole owner of, each Pledged Mortgage free and clear of any pledge, lien,
        encumbrance or security interest and had full right and authority,
        subject to no interest or participation of, or agreement with, any other
        party (other than the Servicers pursuant to the Servicing Agreements) to
        pledge and assign the same pursuant to the Indenture. Except as
        previously described in writing to the Trustee and MBIA with respect to
        the Pledged Mortgages, there is only one executed Mortgage Note not
        stamped as a duplicate. The rights with respect to each Pledged Mortgage
        are assignable by the Seller without the consent of any Person other
        than consents which will have been obtained on or before the Closing
        Date.

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

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

                      (7) To best of Seller's knowledge there are no mechanics'
        liens or claims for work, labor or material affecting any Mortgaged
        Property which are or may be a lien prior to, or equal with, the lien of
        such Mortgage, except those which are insured against by the title
        insurance policy referred to in item (11) below. No Mortgaged Property
        is damaged by waste, fire, earthquake or earth movement, windstorm,
        flood, other types of water damage, tornado or other casualty so as to
        affect adversely the 


                                     S-III-2

<PAGE>   100


        value of the property as security for such Pledged Mortgage or the use
        for which the premises was intended.

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

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

                      (10) As of the Closing Date, no prior holder of any
        Mortgage has modified the Mortgage in any material respect (except that
        a Pledged Mortgage may have been modified by a written instrument which
        has been recorded or submitted for recordation, if necessary, to protect
        the interests of the Bondholders and which has been delivered to the
        Trustee); satisfied, cancelled, subordinated or rescinded such Mortgage
        in whole or in part; released the related Mortgaged Property in whole or
        in part from the lien of such Mortgage; or executed any instrument of
        release, cancellation, subordination, rescission, modification or
        satisfaction with respect thereto. No action on the part of any
        Mortgagor which would otherwise cause the related Pledged Mortgage to be
        in default has been waived.

                      (11) A lender's policy of title insurance together with a
        condominium endorsement and an extended coverage endorsement, if
        applicable, and a variable rate endorsement in an amount at least equal
        to the Cut-off Date Stated Principal Balance of each such Pledged
        Mortgage or a commitment (binder) to issue the same was effective on the
        date of the origination of each Pledged Mortgage, each such policy is
        valid and remains in full force and effect, and each such policy was
        issued by a title insurer qualified to do business in the jurisdiction
        where the Mortgaged Property is located and acceptable to FNMA or FHLMC
        and is in a form acceptable to FNMA or FHLMC, which policy insures the
        Seller and successor owners of indebtedness secured by the insured


                                     S-III-3

        Mortgage, (a) as to the first priority lien of the Mortgage subject to
        the exceptions set forth in paragraph (3) above and (b) against loss by
        reason of the invalidity or unenforceability of the lien resulting from
        the provisions of the Mortgage Note and Mortgage with respect to
        adjustment in the Mortgage Rate and Scheduled Payment; to the best of
        the Seller's knowledge, no claims have been made under such mortgage
        title insurance policy and no prior holder of the related Mortgage,
        including the Seller, the Company or the Issuer, has done, by act or
        omission, anything which would impair the coverage of such mortgage
        title insurance policy.

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

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

                      (14)   To the best of Seller's knowledge, no
        improvement located on or being part of the Mortgaged
        Property is in violation of any applicable zoning law or
        regulation. To the best of Seller's knowledge, all inspections,
        licenses and certificates required to be made or issued with respect to
        all occupied portions of the Mortgaged Property and, with respect to the
        use and occupancy of the same, including but not limited to certificates
        of occupancy and fire underwriting certificates, have been made or
        obtained from the appropriate authorities, unless the lack thereof would
        not have a material adverse effect on the value of such Mortgaged
        Property, and the Mortgaged Property is lawfully occupied under
        applicable law. To the best of the Seller's knowledge, all parties which
        have had any interest in each Pledged Mortgage whether as Mortgagee,
        assignee, pledgee or otherwise, and including, without limitation, the
        Seller and/or during the period in which they held and disposed such
        interest, were, in compliance with any and all applicable licensing
        requirements of the 


                                     S-III-4

<PAGE>   102

        laws of the State where in the Property securing the Pledged Mortgage is
        located.

                      (15) The Mortgage Note and the related Mortgage are
        genuine, and each is the legal, valid and binding obligation of the
        maker thereof, enforceable in accordance with its terms and under
        applicable law. To the best of Seller's knowledge, all parties to the
        Mortgage Note and the Mortgage had legal capacity to execute the
        Mortgage Note and the Mortgage and each Mortgage Note and Mortgage have
        been duly and properly executed by such parties. Each Pledge Mortgage
        was recorded, and all subsequent assignments of the original Mortgage
        have been recorded in appropriate jurisdictions where recordation is
        necessary to perfect the lien thereof as against creditors of the
        Seller. Each Pledged Mortgage and assignment of Pledged Mortgage is in
        recordable form and is acceptable for recording under the laws of the
        jurisdiction in the property securing such Mortgage is located. The sale
        of the Pledged Mortgages and the related Mortgage Notes does not violate
        the terms and provisions of any loan or agreement to which the Seller is
        party or to which it is bound.

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

                      (17) The related Mortgage contains customary and
        enforceable provisions which render the rights and remedies of the
        holder thereof adequate for the realization against the Mortgaged
        Property of the benefits of the security, including, (i) in the case of
        a Mortgage designated as a deed of trust, by trustee's sale, and (ii)
        otherwise by judicial foreclosure. Each Pledged Mortgage contains a
        provision for the acceleration of the unpaid principal balance of the
        related Pledged Mortgage in the event that the property securing such
        Pledged Mortgage is sold or


                                     S-III-5

<PAGE>   103


        transferred without the prior written consent of the Mortgagee
        thereunder.

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

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

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

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

                      (22) No Pledged Mortgage has a shared appreciation
        feature, or other contingent interest feature. With respect to each
        Pledged Mortgage, the payments required of the Mortgagor are and will be
        such that the Pledged Mortgage will fully amortize over its term. No
        Pledged Mortgage requires a balloon payment at the end of its term.

                      (23) Each Pledged Mortgage is assumable if the proposed
        transferee submits certain information required to evaluate the
        transferee's ability to repay the Pledged Mortgage and the holder of the
        Mortgage Note reasonably determines that the security for the Pledged
        Mortgage would not be impaired by the assumption.

                      (24) Except with respect to_________Pledged Mortgages 
        representing approximately ___% of the Cut-off Date Pool 


                                     S-III-6

<PAGE>   104


        Principal Balance, each Pledged Mortgage which had a Loan-to-Value
        Ratio at origination in excess of 80% is the subject of a Primary
        Insurance Policy that insures that portion of the original principal
        balance of the related Pledged Mortgage equal to the product of the
        original principal balance thereof and a fraction, the numerator of
        which is the excess of the original principal balance of the related
        Pledged Mortgage over 75% of the lesser of the appraised value and
        selling price of the related Mortgaged Property and the denominator of
        which is the original principal balance of the related Pledged Mortgage,
        plus accrued interest thereon and related foreclosure expenses. Each
        such Primary Insurance Policy is issued by a Qualified Insurer
        acceptable to each of the Rating Agencies. All provisions of any such
        Primary Insurance Policy have been and are being complied with, any such
        policy is in full force and effect, and all premiums due thereunder have
        been paid. Any Mortgage subject to any such Primary Insurance Policy
        obligates the Mortgagor thereunder to maintain such insurance and to pay
        all premiums and charges in connection therewith. The Mortgage Rate for
        each Pledged Mortgage is net of any such insurance premium.

                      (25) At the Cut-off Date, the improvements upon each
        Mortgaged Property are covered by a valid and existing hazard insurance
        policy with a generally acceptable carrier that provides for fire and
        extended coverage and coverage for such other hazards as are customary
        in the area where the Mortgaged Property is located in an amount which
        is at least equal to the lesser of (i) the maximum insurable value of
        the improvements securing such Pledged Mortgage or (ii) the greater of
        (a) the outstanding principal balance of the Pledged Mortgage and (b) an
        amount such that the proceeds of such policy shall be sufficient to
        prevent the Mortgagor and/or the mortgagee from becoming a co-insurer.
        If the Mortgaged Property is a condominium unit, it is included under
        the coverage afforded by a blanket policy for the condominium unit. All
        such individual insurance policies and all flood policies referred to in
        item (26) below contain a standard mortgagee clause naming the
        applicable Servicer or the original mortgagee, and its successors in
        interest, as mortgagee, and the Seller has received no notice that any
        premiums due and payable thereon have not 


                                     S-III-7

<PAGE>   105


        been paid; the Mortgage obligates the Mortgagor thereunder to maintain
        all such insurance including flood insurance at the Mortgagor's cost and
        expense, and upon the Mortgagor's failure to do so, authorizes the
        holder of the Mortgage to obtain and maintain such insurance at the
        Mortgagor's cost and expense and to seek reimbursement therefor from the
        Mortgagor.

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

                      (27) To the best of the Seller's knowledge, there is no
        proceeding pending or threatened for the total or partial condemnation
        of any Mortgaged Property, nor is such a proceeding currently occurring.
        There are no proceedings pending, or to the best of the Seller's
        knowledge threatened, wherein the Mortgagor or any governmental agency
        has alleged that any Pledged Mortgage is illegal or unenforceable.

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

<PAGE>   106


                      (29) Other than with respect to Mortgaged Property
        underlying a Cooperative Loan, each Mortgaged Property is improved by a
        one- to four-family residential dwelling including condominium units and
        dwelling units in PUDs, which, to the best of Seller's knowledge, does
        not include mobile homes and does not constitute other than real
        property under state law.

                      (30) Each Pledged Mortgage is being serviced by the Master
        Servicer or a Servicer as provided in Section 3(b) of the Master
        Servicing Agreement.

                      (31) There is no obligation on the part of the Seller or
        any other party under the terms of the Mortgage or related Mortgage Note
        to make payments in addition to those made by the Mortgagor. The Seller
        has clearly fulfilled all obligations under or in connection with the
        acquisition and assignment on the Pledged Mortgages and the related
        Mortgage Notes, including, without limitation, giving any notices or
        consents necessary to affect the acquisition of the Pledged Mortgages
        and the related Mortgage Notes by the Trustee on behalf of the Trust and
        has done nothing to impair the rights of the Trustee, MBIA or the
        Bondholders with respect therein.

                      (32) Any future advances made prior to the Cut-off Date
        have been consolidated with the outstanding principal amount secured by
        the Mortgage, and the secured principal amount, as consolidated, bears a
        single interest rate and single repayment term reflected on the Schedule
        of Pledged Mortgages. The consolidated principal amount does not exceed
        the original principal amount of the Pledged Mortgage. The Mortgage Note
        does not permit or obligate the Master Servicer to make future advances
        to the Mortgagor at the option of the Mortgagor. The applicable interest
        rate is adjusted in accordance with the terms of the related Mortgage
        Note. All required notices of interest rate adjustments have been sent
        to each Mortgagor on a timely basis and the computations of such
        adjustments were properly calculated. All interest rate adjustments have
        been made in accordance with all applicable law.

                      (33) There are no defaults in complying with the terms of
        the Mortgage, and all taxes, governmental assessments, insurance
        premiums, water, sewer and municipal charges, leasehold payments or
        ground rents which previously became due and owing have been paid, or an
        escrow of funds has been established in an amount sufficient to pay for
        every such item which remains unpaid and which has been assessed, but is
        not yet due and payable. Except for (A) payments in the nature of escrow
        payments, and (B) interest accruing from the date of the Mortgage Note
        or date of disbursement of the Mortgage proceeds, whichever is later, to
        the day which precedes by one month the Due Date of the first
        installment of principal and interest, including without limitation
        taxes and insurance payments, the related Servicer has not advanced
        funds, or induced, solicited or knowingly received any advance of funds
        by a party other than the Mortgagor, directly or indirectly, for the
        payment of any amount required by the Mortgage.

                      (34) Each Pledged Mortgage was acquired by Seller in all
        material respects in accordance with the guidelines set forth in the
        Prospectus Supplement. The Seller used no selection procedure that
        identified the Pledged Mortgages as being less desirable or valuable
        than other comparable mortgage loans acquired by the Seller. The Pledged
        Mortgages are representative of the Seller's portfolio of mortgage
        loans.

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

                      (36) None of the Pledged Mortgages is a graduated payment
        mortgage loan or a growing equity mortgage loan or subject to a buy down
        or similar arrangement.

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

                      (38) The sale, transfer, assignment and conveyance of
        Pledged Mortgages by the Seller pursuant to the Mortgage Sale Agreement
        is not subject to and will not result in any tax, fee or governmental
        charge payable by the Seller, the Issuer, the Depositor or the Trustee
        to any federal, state or local government ("Transfer Taxes") other than
        Transfer Taxes which have or will be paid by the Seller as due. In the
        event that the Issuer, the Depositor or the Trustee receives actual
        notice of any Transfer Taxes arising out of the transfer, assignment and
        conveyance of the Pledged Mortgages, on written demand by the Issuer,
        the Depositor or the Trustee, or upon the Seller's otherwise being given
        notice thereof by the Issuer, the Depositor or the Trustee, the Seller
        shall pay, and otherwise indemnify and hold the Issuer, the Trustee and
        MBIA harmless, on an after-tax basis, from and against any and all such
        Transfer Taxes (it being understood that the Bondholders, the Trustee,
        the Issuer, the Depositor and MBIA shall have no obligation to pay such
        Transfer Taxes).

                      (39)   None of the Pledged Mortgages are "consumer
        credit contracts" or "purchased money loans" for goods or
        services as such terms are defined in 16 C.F.R. Section 433.1 and
        none of the Pledged Mortgages are "mortgages" as such term
        is defined in 15 U.S.C. Section 1602(aa).

                            SEQUOIA MORTGAGE TRUST 1
                          Collateralized Mortgage Bonds

                  Representations and Warranties of the Issuer

        Sequoia Mortgage Trust 1 (the "Issuer") hereby makes the representations
and warranties set forth in this Schedule IV to the Master Servicer, MBIA and
the Trustee, as of the Closing Date. Capitalized terms used but not otherwise
defined in this Schedule IV shall have the meanings ascribed thereto in the
Master Servicing Agreement (the "Master Servicing Agreement") relating to the
above-referenced Series, among Norwest Bank Minnesota, N.A., as Master Servicer,
Sequoia Mortgage Trust 1, as Issuer, and First Union National Bank, as Trustee.

               (A) The Issuer is a statutory business trust duly organized,
        validly existing and in good standing under the laws of the State of
        Delaware, and possesses all requisite authority, power, licenses,
        permits and franchises to conduct any and all business contemplated by
        the Master Servicing Agreement and to comply with its obligations under
        the terms of this Agreement, the performance of which have been duly
        authorized by all necessary action.

               (B) Neither the execution and delivery of the Master Servicing
        Agreement by the Issuer, nor the performance and compliance with the
        terms thereof by the Issuer will (A) result in a material breach of any
        term or provision of the instruments creating the Issuer or governing
        its operations, or (B) materially conflict with, result in a material
        breach, violation or acceleration of, or result in a material default
        under, the terms of any other material agreement or instrument to which
        the Issuer is a party or by which it may be bound, or (C) constitute a
        material violation of any statute, order or regulation applicable to the
        Issuer of any court, regulatory body, administrative agency or
        governmental body having jurisdiction over the Issuer; and the Issuer is
        not in breach or violation of any material indenture or other material
        agreement or instrument, or in violation of any statute, order or
        regulation of any court, regulatory body, administrative agency or


                                     S-IV-1

        governmental body having jurisdiction over it which breach or violation
        may materially impair the Issuer's ability to perform or meet any of its
        obligations under the Master Servicing Agreement.

               (C) This Agreement, and all documents and instruments
        contemplated hereby, which are executed and delivered by the Issuer,
        will, assuming due authorization, execution by and delivery to the other
        parties hereto and thereto, constitute valid, legal and binding
        obligations of the Issuer, enforceable in accordance with their
        respective terms, except that (a) the enforceability thereof may be
        limited by bankruptcy, insolvency, moratorium, receivership and other
        similar laws relating to creditors' rights generally and (b) the remedy
        of specific performance and injunctive and other forms of equitable
        relief may be subject to equitable defenses and to the discretion of the
        court before which any proceeding therefor may be brought.

               (D) No litigation is pending or, to the best of the Issuer's
        knowledge, threatened against the Issuer that would materially and
        adversely affect the execution, delivery or enforceability of the Master
        Servicing Agreement or the ability of the Issuer to perform its
        obligations thereunder.

               (E) Immediately prior to the pledge of the Pledged Mortgages to
        the Trustee, the Issuer had good title to, and was the sole owner of,
        each Pledged Mortgage free and clear of any liens, charges or
        encumbrances or any ownership or participation interests in favor of any
        other Person.
