                                  AMENDMENT TO
                  HADCO CORPORATION NON-QUALIFIED STOCK OPTION
                                  PLAN OF 1995

         This Amendment (the "Amendment") to the Hadco Corporation Non-Qualified
Stock Option Plan of 1995 (the "Plan") is effective as of April 17, 2000. The
Plan shall be amended as follows:

         Sections 11 (b) and (c) shall be deleted in their entirety and replaced
with the following:

         (b) Upon any sale of all or substantially all of the assets of the
Company, or upon any merger, consolidation or tender offer in respect of which
the stockholders holding all of the Company's outstanding voting securities
immediately prior to the consummation thereof, hold less than 50% of all of the
Company's outstanding voting securities immediately after such consummation
(each of the foregoing sale, merger, consolidation or tender offer hereinafter
called an "Acquisition"), then the date upon which all then outstanding options
granted under this Plan become fully vested and exercisable shall be
automatically accelerated to occur immediately prior to the consummation of such
Acquisition. Notwithstanding any language in any option agreement between the
Company and an optionee, in no event shall any outstanding option be subject to
forfeiture solely as a result of its non-exercise after the acceleration of
vesting described above in this subsection and prior to the consummation of an
Acquisition.

         (c) In the event of a recapitalization or reorganization of the Company
pursuant to which securities of the Company or of another corporation are issued
with respect to the outstanding shares of Common Stock, an optionee upon
exercising an option shall be entitled to receive for the purchase price paid
upon such exercise securities he or she would have received if he or she had
exercised such option prior to such recapitalization or reorganization.

         Except as specifically amended hereby, each of the terms and conditions
of the Plan is hereby ratified and confirmed and shall remain in full force and
effect.<PAGE>   1

         (b) The aggregate principal amount of Notes of each Series which may be
authenticated and delivered under this Indenture is specified in the applicable
Supplement, except for Notes authenticated and delivered upon registration of
transfer or in exchange for or in lieu of, other Notes pursuant to Sections
2.04, 2.05, 2.07 or 9.05 hereof. The Notes shall be issuable only as registered
Notes without coupons in minimum denominations of $500,000 and integral
multiples of $0.01 in excess thereof; provided, that the foregoing shall not
restrict or prevent the transfer in accordance with Sections 2.05 and 2.06
hereof of any Note with a remaining Outstanding Principal Amount of less than
its original minimum denomination.

         SECTION 2.03 EXECUTION, AUTHENTICATION, DELIVERY AND DATING.

         (a) The Notes shall be manually executed on behalf of the Issuer by its
President, Treasurer or one of its Vice Presidents. Notes bearing the manual
signatures of individuals who were at any time the proper officers of the Issuer
shall bind the Issuer, notwithstanding that such individuals or any of them have
ceased to hold such offices prior to the authentication or delivery of such
Notes or did not hold offices at the date of authentication or delivery of such
Notes.

         (b) Each Note shall bear on its face the applicable Delivery Date and
be dated as of the date of its authentication.

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

         SECTION 2.04 [RESERVED]

         SECTION 2.05 REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE.

         (a) The Issuer shall cause to be kept at an office or agency to be
maintained by the Issuer in accordance with Section 11.02(m) hereof a register
(the "Note Register"), in which, subject to such reasonable regulations as it
may prescribe, the Issuer shall provide for the registration of Notes and the
registration of transfers of Notes. Norwest Bank Minnesota, National
Association, Sixth Street and Marquette Avenue, MAC N9311-161, Minneapolis,
Minnesota 55479, is hereby appointed "Note

                                       22
<PAGE>   27

Registrar" for the purpose of registering Notes and transfers of Notes as herein
provided. The Indenture Trustee shall have the right to examine the Note
Register at all reasonable times and to rely conclusively upon a Certificate of
the Note Registrar as to the names and addresses of the Holders of the Notes and
the principal amounts and numbers of such Notes as held.

         (b) Upon surrender for registration of transfer of any Note at the
office or agency of the Issuer to be maintained as provided in Section 11.02(m)
hereof and subject to the conditions set forth in Section 2.06 hereof, the
Issuer shall execute, and the Indenture Trustee or its agent shall authenticate
and deliver, in the name of the designated transferee or transferees, one or
more new Notes of any authorized denominations, and of a like aggregate
principal amount, Series and Stated Maturity Date.

         (c) At the option of the Holder, Notes of a Series may be exchanged for
other Notes of such Series of any authorized denominations and of a like
aggregate principal amount and Stated Maturity Date, upon surrender of the Notes
to be exchanged at such office or agency. Whenever any Notes are so surrendered
for exchange, the Issuer shall execute, and the Indenture Trustee or its agent
shall authenticate and deliver, the Notes which the Noteholder making the
exchange is entitled to receive.

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

         (e) Every Note presented or surrendered for registration of transfer or
exchange shall (if so required by the Issuer or the Note Registrar) be duly
endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Issuer and the Note Registrar duly executed, by the Holder
thereof or his attorney duly authorized in writing.

         (f) No service charge shall be made to a Holder for any registration of
transfer or exchange of Notes, but the Issuer may require payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
connection with any registration of transfer or exchange of Notes, other than
exchanges pursuant to Section 2.04 or 9.05 hereof not involving any registration
of transfer.

         SECTION 2.06 LIMITATION ON TRANSFER AND EXCHANGE.

         (a) The Notes have not been registered or qualified under the
Securities Act or the securities laws of any state. No transfer of any Note
shall be made unless that transfer is made in a transaction which does not
require registration or qualification under the Securities Act or under
applicable state securities or "Blue Sky" laws. In the event that a transfer is
to be made, such Noteholder's prospective transferee shall deliver to the
Indenture Trustee either (i) an investment letter substantially in the form set
forth on Exhibit C hereto (the "Investment Letter") or (ii) an opinion of
counsel that the transfer is exempt from such registration or qualification
under the Securities Act (which opinion shall not be at the expense of the
Issuer, the Indenture Trustee, the Servicer or the Trust Estate). Neither the
Issuer nor the Indenture Trustee is obligated to register or qualify the Notes
under the Securities Act or any other securities law. Any such Holder desiring
to effect such transfer shall, and does hereby agree to, indemnify the Indenture
Trustee, the Note Insurer and the Issuer against any liability, cost or expense
(including attorneys' fees) that may result if the transfer is not so exempt or
is not made in accordance with such federal and state laws. MicroFinancial
Incorporated (whether or not acting as Servicer) shall provide to the Indenture
Trustee the information required to be delivered to Holders and prospective
transferees of Notes in connection with resales of the Notes to permit
compliance with Rule 144A promulgated under the Securities Act in connection
with such resales and, promptly upon its receipt thereof, the Indenture

                                       23
<PAGE>   28

Trustee shall furnish such information to any Holder or any prospective
transferee designated by a Holder.

         (b) No acquisition or transfer of a Note or any interest therein may be
made to any "Benefit Plan Investor"(as defined in 29 C.F.R. ss.2510.3-101) or to
any Person who is directly or indirectly purchasing the Notes or an interest
therein on behalf of, as named fiduciary of, as trustee of, or with assets of,
such a Benefit Plan Investor unless the Indenture Trustee is provided with
evidence that establishes to the reasonable satisfaction of the Indenture
Trustee that (i) either no "prohibited transaction" under ERISA or the Code will
occur in connection with such prospective acquirer's or transferee's acquisition
and holding of the Notes or that the acquisition and holding of the Notes by
such prospective acquirer or transferee is subject to a statutory or
administrative exemption, and (ii) that the prospective acquirer's or
transferee's acquisition and holding will not subject the Issuer, the Servicer
or the Indenture Trustee to any obligation or liability (including obligations
or liabilities under ERISA or Section 4975 of the Code) in addition to those
explicitly undertaken in the Transaction Documents. In the absence of a change
in applicable law, the delivery of an executed Investment Letter shall be deemed
to provide satisfactory evidence of compliance with this Section 2.06(b).

         (c) The Indenture Trustee shall have no liability to the Trust Estate
or any Noteholder arising from a transfer of any such Note in reliance upon a
certification described in this Section 2.06.

         SECTION 2.07 MUTILATED, DESTROYED, LOST OR STOLEN NOTE.

         If (i) any mutilated Note is surrendered to the Note Registrar, or the
Indenture Trustee receives evidence to its satisfaction of the destruction, loss
or theft of any Note, and (ii) there is delivered to the Indenture Trustee and
the Note Insurer such security or indemnity as may be required by the Indenture
Trustee to save the Issuer, the Indenture Trustee and the Note Insurer or any
agent of any of them harmless (it being understood that the unsecured written
undertaking of any domestic institutional Holder shall be deemed to be
sufficient for such purposes), then, in the absence of notice to the Issuer or
the Note Registrar that such Note has been acquired by a bona fide purchaser,
the Issuer shall execute and, upon its request, the Indenture Trustee shall
authenticate and deliver, in exchange for or in lieu of any such mutilated,
destroyed, lost or stolen Note, a new Note of the same Series, initial principal
amount and Stated Maturity Date, bearing a number not contemporaneously
outstanding. If after the delivery of such new Note, a bona fide purchaser of
the original Note in lieu of which such new Note was issued presents for payment
such original Note, the Note Insurer, the Issuer and the Indenture Trustee shall
be entitled to recover such new Note from the Person to whom it was delivered or
any Person taking therefrom, except a bona fide purchaser, and shall be entitled
to recover upon the security or indemnity provided therefor to the extent of any
loss, damage, cost or expenses incurred by the Note Insurer, the Issuer or the
Indenture Trustee or any agent of any of them in connection therewith. If any
such mutilated, destroyed, lost or stolen Note shall have become or shall be
about to become due and payable, or shall have become subject to redemption in
full, in lieu of issuing a new Note, the Issuer may pay such Note without
surrender thereof, except that any mutilated Note shall be surrendered.

         No service charge shall be made to a Holder for any registration of
transfer or exchange of Notes, but the Issuer may require payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
connection with any registration of transfer or exchange of Notes, other than
exchanges pursuant to Section 2.05 or 9.05 hereof not involving any registration
of transfer.

         Every new Note issued pursuant to this Section 2.07, in lieu of any
destroyed, lost or stolen Note, shall constitute an original additional
contractual obligation of the Issuer, whether or not the destroyed, lost or
stolen Note shall be at any time enforceable by anyone, and shall be entitled to
all the benefits of

                                       24
<PAGE>   29

this Indenture equally and proportionately with any and all other Notes duly
issued hereunder. Upon the issuance of any new Note under this Section, the
Indenture Trustee or Note Registrar may require the payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in relation
thereto.

         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 Notes.

         SECTION 2.08 PAYMENT OF PRINCIPAL AND INTEREST; PRINCIPAL AND INTEREST
                      RIGHTS PRESERVED.

         (a) Unless otherwise specified in the applicable Supplement, for each
applicable Accrual Period, the Notes of each Series shall accrue interest on the
Outstanding Principal Amount thereof (as of the first day of the related Accrual
Period) from and including the first day to and including the last day of such
Accrual Period at the related Note Interest Rate and using the related Interest
Calculation Convention. Interest shall be due and payable in arrears on each
Payment Date, with each payment of interest calculated as described above on the
Outstanding Principal Amount of the Notes immediately following the making of
payments on the preceding Payment Date or on the applicable Delivery Date, if
there has not been a preceding Payment Date. In making any such interest
payment, if the interest calculation with respect to a Note shall result in a
portion of such payment being less than $0.01, then such payment shall be
decreased to the nearest whole cent, and no subsequent adjustment shall be made
in respect thereof.

         (b) The principal of each Note shall be payable in installments ending
no later than the applicable Stated Maturity Date thereof unless such Note
becomes due and payable at an earlier date by declaration of acceleration, call
for redemption or otherwise. All reductions in the principal amount of a Note
effected by payments of installments of principal made on any Payment Date shall
be binding upon all future Holders of such Note and of any Note issued upon the
registration of transfer thereof or in exchange therefor or in lieu thereof,
whether or not such payment is noted on such Note. Each installment of principal
payable on the Notes shall be in an amount equal to the Principal Distribution
Amount and the Additional Principal Amount, if any, available to be paid in
accordance with the priorities of Sections 12.02(d) hereof. The principal
payable on the Notes of each Series shall be paid in accordance with the terms
of the applicable Supplement or, if not specified therein, then on each Payment
Date beginning on the applicable Initial Payment Date and ending on the
applicable Final Payment Date, and with respect to all of the Notes within a
Series, on a pro rata basis based upon the ratio that the Outstanding Principal
Amount of a Note bears to the Outstanding Principal Amount of all Notes of such
Series; provided, that if as a result of such proration a portion of such
principal would be less than $0.01, then such payment shall be increased to the
nearest whole cent, and such portion shall be deducted from the next succeeding
principal payment.

         (c) The principal of and interest on the Notes are payable by check
mailed by first-class mail to the Person whose name appears as the Registered
Holder of such Note on the Note Register at the address of such Person as it
appears on the Note Register except that such payment shall be by wire transfer
in immediately available funds to the account specified in the Note Purchase
Agreement (or such alternative account specified in writing to the Indenture
Trustee by any Registered Holder at least five Business Days prior to the Record
Date for the Payment Date on which wire transfers will commence), in such coin
or currency of the United States of America as at the time of payment is legal
tender for the payment of public and private debts. All payments on the Notes
shall be paid without any requirement of presentment. The Issuer shall notify
the Person in whose name a Note is registered at the close of

                                       25
<PAGE>   30

business on the Record Date next preceding the Payment Date on which the Issuer
expects that the final installment of principal of such Note will be paid that
the Issuer expects that such final installment will be paid on such Payment
Date. Such notice shall be mailed no later than the tenth day prior to such
Payment Date and shall specify the place where such Note may be surrendered.
Funds representing any such checks returned undeliverable shall be held in
accordance with Section 7.16 hereof. Each Noteholder shall surrender its Note to
the Indenture Trustee promptly following payment of the final installment of
principal of such Note. Each Holder of Notes does by its acceptance of a Note
agree to indemnify the Indenture Trustee, the Note Insurer and the Issuer
against any liability, cost or expenses (including attorneys' fees) that may
result if such Noteholder fails to so deliver such Note.

         (d) Notwithstanding any of the foregoing provisions with respect to
payments of principal of and interest on the Notes, if the Notes have become or
been declared due and payable following an Event of Default and such
acceleration of maturity and its consequences have not been rescinded and
annulled, then payments of principal of and interest on such Notes shall be made
in accordance with Section 6.08 hereof.

         SECTION 2.09 PERSONS DEEMED OWNER.

         Prior to due presentment for registration of transfer of any Note, the
Issuer, the Note Insurer, the Indenture Trustee and any agent of the Issuer, the
Note Insurer or the Indenture Trustee shall treat the Person in whose name any
Note is registered as the owner of such Note for the purpose of receiving
payments of principal of and interest on such Note and for all other purposes
whatsoever, whether or not such Note be overdue, and neither the Issuer, the
Note Insurer, the Indenture Trustee nor any agent of the Issuer, the Note
Insurer or the Indenture Trustee shall be affected by notice to the contrary.

         SECTION 2.10 CANCELLATION.

         All Notes surrendered to the Indenture Trustee for payment,
registration of transfer or exchange (including Notes surrendered to any Person
other than the Indenture Trustee which shall be delivered to the Indenture
Trustee) shall be promptly canceled by the Indenture Trustee. No Notes shall be
authenticated in lieu of or in exchange for any Notes canceled as provided in
this Section 2.10, except as expressly permitted by this Indenture. All canceled
Notes held by the Indenture Trustee shall be disposed of by the Indenture
Trustee as is customary with its standard practice.

         SECTION 2.11 TAX TREATMENT.

         The Issuer has structured this Indenture and the Notes with the
intention that the Notes qualify under applicable tax laws as indebtedness
secured by the Trust Estate. The Issuer, the Indenture Trustee, the Servicer,
the Note Insurer and each Noteholder, by acceptance of its Note (and any Person
that is a beneficial owner of any interest in a Note, by virtue of such Person's
acquisition of a beneficial interest therein) agree to report the transactions
contemplated hereby in accordance with such stated intentions unless and until
determined to the contrary by an applicable taxing authority.

         any order of any court or administrative agency entered in any
         proceeding to which the Issuer is a party or by which it may be bound
         or to which it may be subject, and (C) that all conditions precedent
         provided in this Indenture relating to the execution and delivery of

         Series will be characterized as debt for tax purposes and that the

         in the Trust Estate, (iii) confirming true sale and the
         nonconsolidation matters of the Issuer and the Company or the Servicer

         Company or the Servicer, and (iv) confirming basic corporate matters
         and that the Issuer is not required to be registered as an "investment
         company" under the Investment Company Act of 1940;

                  (x) the Issuer shall have delivered to the Indenture Trustee
         evidence of the deposit by the Issuer into the Collection Account of
         any amounts due and paid under the Contracts of such Series of Notes
         since the related Cut-off Date and evidence of the deposit by the
         Issuer of any applicable amounts to the Cash Collateral Account;

                  (xi) the Issuer shall have delivered to the relevant party or

         such Series of Notes or as may be required by the Note Insurer; and

                  (xii) the Indenture Trustee shall have received from each of
         the Note Insurer and the Issuer an officer's certificate certifying
         that no Note Insurer Default has occurred and is continuing with

         Upon satisfaction of the above conditions, the Indenture Trustee shall
execute the Supplement and shall authenticate and deliver to or upon the order
of the Issuer the applicable Notes, and provide notice to all existing
Noteholders of the issuance of such Series of Notes.

         SECTION 4.03 SECURITY FOR NOTES.

         (a) The Issuer and the Company shall file UCC-1 financing statements
described in Sections 4.01(f) and 4.02(b)(vi) hereof in accordance with such
Sections. In addition, as soon as practicable but no later than 30 days after
the Initial Delivery Date and any subsequent Delivery Date or Acquisition Date,
as the case may be, the Issuer and the Company shall file with respect to all
Contracts Granted to the Indenture Trustee on such date as to which the original
cost of the underlying Equipment was in excess of $10,000, UCC assignments
assigning to the Indenture Trustee on behalf of the Holders of the Notes and the
Note Insurer, the Company's security interest in the Equipment under such
Contracts. From time to time, the Servicer shall take or cause to be taken such
actions and execute such documents as are necessary to perfect and protect the
Indenture Trustee's and the Note Insurer's respective interests in the Contracts
and the Equipment owned by the Issuer (provided that, with respect to financing
statements filed regarding Equipment, the original cost of such Equipment was in
excess of $10,000) against all other Persons, including, without limitation, the
filing of financing statements, amendments thereto and continuation statements,
the execution of transfer instruments and the making of notations on or taking
possession of all records or documents of title.

         (b) If any change in either the Company's or the Issuer's name,
identity, structure or the location of its principal place of business, chief
executive office or jurisdiction of organization occurs, then the Issuer shall,
or the Issuer shall cause the Company, to deliver 30 days prior written notice
of such change or relocation to the Servicer, the Note Insurer and the Indenture
Trustee and no later than the effective date of such change or relocation, the
Servicer shall file such amendments or statements as may be required to preserve
and protect the Indenture Trustee's and the Note Insurer's respective interests
in the Trust Estate.

         (c) During the term of this Indenture, the Issuer shall maintain each
of its chief executive office, principal place of business and jurisdiction of
organization in one of the States of the United States.

                                       31
<PAGE>   36

         (d) The Servicer agrees to pay all reasonable costs and disbursements
in connection with the perfection and the maintenance of perfection, as against
all third parties, of the Indenture Trustee's and the Note Insurer's respective
right, title and interest in and to the Trust Estate (other than with respect to
the Equipment related to a Contract the original cost of which was less than
$10,000).

         (e) The Indenture Trustee shall hold the original manually executed
counterpart of each Contract at its office in the State of Minnesota, and at any
such new address in the State of Minnesota as the Indenture Trustee shall inform
the Servicer, the Issuer and the Note Insurer in writing from time to time. The
Indenture Trustee shall hold each Contract for the benefit of Noteholders and
the Note Insurer, and maintain accurate records pertaining to each Contract to
maintain a current inventory thereof. The Indenture Trustee may, if requested by
the Servicer in writing in the form attached hereto as Exhibit F for purposes of
servicing a Contract, temporarily release to the Servicer such Contract. Any
Contract temporarily released from the custody of the Indenture Trustee to the
Servicer or its agents shall have stamped on it prior to delivery a legend to
the effect that the Contract is subject to a security interest in favor of
Norwest Bank Minnesota, National Association, as Indenture Trustee. The Servicer
shall promptly return the Contract to the Indenture Trustee when the need
therefor no longer exists.

         SECTION 4.04 SUBSTITUTION, REMOVAL AND PURCHASE OF CONTRACTS IN TRUST
                      ESTATE.

         (a) NOTICE OF BREACH OF REPRESENTATION OR WARRANTY. If at any time the
Issuer, the Servicer or the Indenture Trustee obtains knowledge (within the
meaning of 7.01(e) hereof, in the case of the Indenture Trustee), discovers or
is notified by the Company, the Issuer, the Note Insurer or the Servicer that
any of the representations and warranties of the Company in the Contract
Acquisition Agreement were incorrect at the time as of which such
representations and warranties were made, then the Person discovering, or
obtaining knowledge or receiving notification of such defect, omission, or
circumstance shall promptly notify the other parties to this Indenture and the
Note Insurer.

         (b) MANDATORY REPURCHASE OR SUBSTITUTION UPON BREACH OF CERTAIN
REPRESENTATIONS OR WARRANTIES. In the event that any representation or warranty
of the Company in the Contract Acquisition Agreement was incorrect as of the
date made and the interests of the Note Insurer or the Holders of any Notes are
materially and adversely affected thereby, or if the Company is otherwise
required to take action under Section 3.03 of the Contract Acquisition Agreement
with respect to such a breach, the Issuer shall require the Company, pursuant to
the Contract Acquisition Agreement, to eliminate or otherwise cure the
circumstance or condition which has caused such breach within 30 days of
discovery or notice thereof by or to the Issuer, the Company or the Servicer. If
the Company fails or the Company or the Servicer is unable to cure such
circumstance or condition in accordance with the Contract Acquisition Agreement,
then the Issuer shall require the Company, pursuant to the Contract Acquisition
Agreement, to substitute a Substitute Contract for or to repurchase at the
Purchase Price, each affected Contract within the time specified in Section 3.03
of the Contract Acquisition Agreement. The proceeds of any such repurchase shall
be remitted by or on behalf of the Issuer to the Servicer for deposit by the
Servicer in the Collection Account pursuant to Section 3.03 of the Servicing
Agreement.

         (c) INDENTURE TRUSTEE TO ACT. If the Issuer fails to enforce the
purchase or substitution obligations of the Company under the Contract
Acquisition Agreement in accordance with clause (b) above, the Indenture Trustee
is hereby appointed attorney-in-fact to act on behalf of and in the name of the
Issuer to require such purchase or substitution.

                                       32
<PAGE>   37

         (d) PROHIBITION ON VOLUNTARY REPURCHASE OR SUBSTITUTION; MANDATORY
DEPOSITS OR SUBSTITUTIONS RELATED TO PREPAID CONTRACTS; DE MINIMIS EXCEPTION TO
PROHIBITION.

                  (i) Except as set forth in subclause (iii) below, no party to
         this Indenture or the Contract Acquisition Agreement may purchase,
         remove or otherwise release any Contract from the Trust Estate, unless
         such purchase, removal or release is required by this Indenture.

                  (ii) In addition to the mandatory repurchase or substitution
         required pursuant to clauses (b) and (c) of this Section 4.04, a
         Contract shall be removed from the Trust Estate if the Servicer permits
         any Customer to prepay or terminate a Contract in accordance with
         Section 3.09 of the Servicing Agreement and all amounts paid by the
         Customer in respect thereof (the "Customer Prepayment Amount") are
         remitted to the Indenture Trustee for deposit to the Collection
         Account. Unless otherwise specified by the terms of such Contract, the
         Servicer may permit the Customer Prepayment Amount to be less than the
         Purchase Price for such Contract (the "Required Prepayment Amount"),
         and cause the release of the related Contract and related Equipment,
         only if the differential between the Required Prepayment Amount and the
         Customer Prepayment Amount (such differential, the "Prepayment
         Differential") is remitted by the Issuer to the Indenture Trustee for
         deposit to the Collection Account; and provided further that the amount
         of such Prepayment Differential shall be deemed to be a voluntary
         repurchase subject to the limitations and restrictions of subclauses
         (iii) and (iv) below. At the option of the Issuer, in lieu of remitting
         the Customer Prepayment Amount and the Prepayment Differential to the
         Indenture Trustee, such removal may instead be effected by the
         substitution of a Substitute Contract in accordance with subclause
         (iii) below, provided that such substitution shall be deemed to be a
         voluntary removal subject to the limitations and restrictions of this
         Section 4.04(d).

                  (iii) In addition to the mandatory repurchases and
         substitutions required under clauses (b), (c) and (d)(ii) of this
         Section 4.04, the Issuer may also, at its option, voluntarily (A)
         repurchase at the Purchase Price any Defaulted Contract or Delinquent
         Contract and (B) substitute a Substitute Contract for any Defaulted
         Contract, Delinquent Contract or prepaid or early terminated Contract.
         Any such Substitute Contract shall meet the same requirements as those
         specified in Section 3.04 of the Contract Acquisition Agreement for
         substitutions by the Company upon the breach of a representation or
         warranty. The sum of (x) the Purchase Price for all repurchased or
         removed Contracts paid by the Company or the Issuer, (y) the aggregate
         IPB of all Substitute Contracts delivered by the Company or the Issuer
         and (z) the aggregate Prepayment Differential paid by the Issuer in
         respect of all prepaid or early terminated Contracts, shall not exceed
         10% of the Aggregate Initial IPB. It is intended that Customer
         Prepayment Amounts not be included in calculating such 10% limitation.

         SECTION 4.05 REQUIREMENTS FOR ALL CONTRACTS IN TRUST ESTATE.

         (a) The Issuer shall comply with the requirements relating to the
acquisition of Contracts as set forth in the Contract Acquisition Agreement
(including compliance with the Eligibility Criteria and Concentration Limits set
forth therein) within the time periods set forth therein. On or prior to the
Business Day preceding each Acquisition Date, the Indenture Trustee will review
the related Contract in accordance with paragraph (b) below. The Indenture
Trustee shall confirm, by execution and delivery of a certificate of the
Indenture Trustee to the Issuer, the Noteholders and the Note Insurer, that the
Indenture Trustee has received the manually executed original of each Contract.
In the case of any Substitute Contracts acquired by the Issuer, the Issuer shall
provide (x) to the Indenture Trustee on the

                                       33
<PAGE>   38

applicable date of delivery the items listed in (i) and (ii) below and (y) to
the Note Insurer the item listed in (i) below:

                  (i) an Officer's Certificate of each of the Company and the
         Issuer, each such Officer's Certificate having attached thereto an
         Amended Contract Schedule and subjecting such Substitute Contract to
         the provisions thereof and hereof and providing with respect to the
         Substitute Contract the information required to supplement the related
         Series Contract Schedule; and

                  (ii) the original manually executed counterpart of the
         Contract relating to such Substitute Contract and, if applicable, all
         or any of the other items included in the Contract File.

The Issuer shall also provide to the Indenture Trustee and the Note Insurer, at
the end of each calendar quarter, evidence that any necessary financing
statements have been filed in accordance with Sections 4.01(f), 4.02(b)(vi) and
4.03 hereof with respect to all such Substitute Contracts acquired during such
period.

         (b) Upon receipt of each Contract, the Indenture Trustee shall confirm
that (i) each such Contract is the original manually executed counterpart of
such Contract; (ii) each such Contract has been executed by the Customer named
thereon; and (iii) each such Contract is identified on the applicable Series
Contract Schedule delivered therewith by Contract number and Customer name. If,
upon such examination of the Contracts, the Indenture Trustee determines that
any such Contract does not satisfy the requirements set forth above or in clause
(a) hereof, or is unable to confirm that the requirements have been met, the
Indenture Trustee shall promptly notify the Issuer, the Servicer and the Note
Insurer by telephone or telecopy and shall deliver an exception report to each
such party setting forth any missing or defective items with respect to such
Contracts.

         (c) Within forty-five days after each Acquisition Date, the Indenture
Trustee shall review any exception report delivered in accordance with paragraph
(b) above and shall verify that it has possession of any missing items noted
thereon. The Indenture Trustee shall send such verification report and notice of
any defects to the Issuer, the Company and the Note Insurer within such
forty-five days and shall take any appropriate action under the Contract
Acquisition Agreement.

         SECTION 4.06 RELEASES OF INDIVIDUAL OR SERIES CONTRACTS IN TRUST
                      ESTATE.

         (a) The Issuer shall be entitled to obtain a release from the lien of
this Indenture for any individual Contract and the related Contract Assets at
any time (i) after a payment by the Company or the Issuer of the Purchase Price
of the Contract and the related Contract Assets, (ii) after a Substitute
Contract is substituted for such Contract and the related Contract Assets, (iii)

of a Defaulted Contract, such Contract and the related Equipment shall be
released from the lien of this Indenture only following the sale, lease or other
disposition of the related Equipment in accordance with Section 3.01(b)(i) of
the Servicing Agreement, provided that the related Recovery and Residual
Proceeds shall not be released from the lien of this Indenture and (z) no
release may be effected pursuant to clause (iii) above if a Trigger Event or
Event of Default shall have occurred and be continuing. In order to effect such
release, the Issuer shall deliver to the Indenture Trustee and the Note Insurer
an Officer's Certificate substantially in the form attached hereto as Exhibit G
(A) identifying the Receivable and the related Contract and

                                       34

Equipment to be released, (B) requesting the release thereof, (C) setting forth
the amount deposited in the Collection Account with respect thereto, in the
event that the subject Contract and the related Equipment are being released
from the lien of this Indenture pursuant to (i) or (iii) above, and (D)
certifying that the amount deposited in the Collection Account (1) equals the
Purchase Price of the Contract, in the event that the subject Contract and the
related Equipment are being released from the lien of this Indenture pursuant to
(i) above or (2) equals the entire amount of Insurance Proceeds or Recoveries
received with respect to such Contract and related Equipment in the event of a
release from the lien of this Indenture pursuant to subclause (y) above.

         (b) In addition, except in the case in which a Series of Notes is
redeemed with the proceeds from a new Series of Notes, the Issuer shall be
entitled, in connection with any permitted redemption or other retirement of a
Series of Notes to obtain a release from the lien of the Indenture for any of
the related Series Contracts and related Contract Assets to the extent that,
after giving effect to such release, the sum of (i) the amount of funds then
held in the Cash Collateral Account and (ii) the Aggregate IPB of the Contracts
remaining in the Trust Estate after giving effect to such release, equals or
exceeds the sum of (y) the Required Collateralization Amount for each Series of
Notes (after giving effect to such payment of principal) plus (z) the
Outstanding Principal Amount of all Series of Notes (after giving effect to such
payment of principal).

         (c) Upon satisfaction of the conditions specified in subsection (a) or
(b), as applicable, the Indenture Trustee shall release from the lien of this
Indenture and deliver to or upon the order of the Issuer (or to or upon the
order of the Company if it has satisfied its obligations under Section 4.04
hereof and Section 3.04 of the Contract Acquisition Agreement with respect to a
Contract) the Contract and all related Contract Assets described in the Issuer's
request for release.

         SECTION 4.07 TRUST ESTATE.

         The Indenture Trustee may, and when required by the provisions of
Articles Four, Five, Six and Twelve hereof shall, execute instruments to release
property from the lien of this Indenture, or convey the Indenture Trustee's
interest in the same, in a manner and under circumstances which are not
inconsistent with the provisions of this Indenture. No party relying upon an
instrument executed by the Indenture Trustee as provided in this Article Four
shall be bound to ascertain the Indenture Trustee's authority, inquire into the
satisfaction of any conditions precedent or see to the application of any
monies.

         SECTION 4.08 NOTICE OF RELEASE.

         The Indenture Trustee shall be entitled to receive at least 10 days
notice of any action to be taken pursuant to Section 4.06 hereof, accompanied by

                           SATISFACTION AND DISCHARGE

         SECTION 5.01 SATISFACTION AND DISCHARGE OF INDENTURE.

         (a) Following payment in full of (i) all of the Notes of each Series
issued hereunder, (ii) the fees and charges of the Indenture Trustee, (iii) all
other obligations of the Issuer under this Indenture and each other Transaction
Document and (iv) all amounts owing to the Note Insurer under each Note
Insurance Agreement, and the release by the Indenture Trustee of the Trust
Estate in accordance with Section 5.01(b) hereof, this Indenture shall be
discharged and the Indenture Trustee shall provide notice of such discharge to
each of the Rating Agencies.

         (b) Upon payment in full of the amounts referred to in clauses (i)
through (iv) of Section 5.01(a) hereof, the Issuer may submit to the Indenture
Trustee an Officer's Certificate requesting the release to the Issuer or its
designee of a stated amount of the funds on deposit in the Cash Collateral
Account and some or all of the other Trust Estate (collectively, the "Withdrawn
Collateral"), accompanied by an Opinion of Counsel reasonably acceptable to the
Controlling Party to the effect that, after the release of the Withdrawn
Collateral, there will remain an amount in the Cash Collateral Account or
otherwise subject to this Indenture at least equal to the payments of interest
previously made on the Outstanding Notes and the Principal Distribution Amounts
that are subject to recapture as preferential transfers pursuant to Section 547
of the Bankruptcy Code or, alternatively, to the effect that no such payments
are subject to recapture. In rendering such Opinion of Counsel, such counsel may
rely as to factual matters, including, without limitation, the date on which
funds were received and the source of funds, upon an Officer's Certificate.
Promptly after receipt of such Officer's Certificate, Opinion of Counsel and
authorization to release from the Controlling Party, the Indenture Trustee shall
release the Withdrawn Collateral from the lien of this Indenture, and deliver
the Withdrawn Collateral to the Issuer or its designee. The Issuer shall be
entitled to deliver more than one such Officer's Certificate and Opinion of
Counsel until the entire Trust Estate is released and delivered to the Issuer or
its designee. Notwithstanding the foregoing, the Controlling Party may waive the
requirement that the Issuer deliver such Officer's Certificate and/or Opinion of
Counsel and authorize the Indenture Trustee by written direction to release all
or a portion of the Cash Collateral Account or other items of the Trust Estate
from the lien of this Indenture upon payment in full of the amounts referred to
in clauses (i) through (iv) of Section 5.01(a) hereof. Notwithstanding
termination of this Indenture, the Indenture Trustee shall remain obligated to
make claims under the Note Insurance Policy with respect to any Preference
Claim.

         (c) In connection with the discharge of this Indenture and the release
of the Trust Estate, the Indenture Trustee shall release from the lien of this
Indenture and deliver to or upon the order of the Issuer all property remaining
in the Trust Estate and shall execute and file, at the expense of the Issuer,
UCC financing statements evidencing such discharge and release.

         SECTION 5.02 APPLICATION OF TRUST MONEY.

         Subject to the last paragraph of Section 7.16 hereof, all monies held
by the Indenture Trustee pursuant to Section 5.01 hereof shall be held in trust
and if invested, shall be invested in Eligible Investments of the type described
in clause (a) of the definition thereof, and applied by the Indenture Trustee,
in accordance with the provisions of the Notes and this Indenture, to the
payment, either directly or through any Paying Agent as the Indenture Trustee
may determine, to the Persons entitled thereto, of the principal and interest
for whose payment such money has been deposited with the Indenture Trustee;

                                       36
<PAGE>   41

such money shall be segregated from other funds to the extent required in this
Indenture and to the extent required by law.

of which is elsewhere in this Section specifically dealt with) which default or
breach has a material adverse effect on the Noteholders or the Note Insurer, and
continuance of such default or breach for a period of 30 days after the earlier
of the Issuer's receipt of written notice of such default or the date on which
the Issuer obtains actual knowledge thereof;

         (e) the entry of a decree or order for relief by a court having
jurisdiction in the premises in respect of the Issuer under the United States
Bankruptcy Code or any other applicable federal or state bankruptcy, insolvency,
reorganization, liquidation or other similar law now or hereafter in effect or
any arrangement with creditors or appointing a receiver, liquidator, assignee,
trustee, or sequestrator (or other similar official) for the Issuer or for any
substantial part of its property, or ordering the winding up or liquidation of

the making by the Issuer of any assignment for the benefit of creditors, or the
admission by it in writing of its inability, or the failure by it generally, to
pay its debts as they become due, or the taking of corporate action by the
Issuer in furtherance of any such action;

         (g) the payment by the Note Insurer of any amounts under any Note
Insurance Policy pursuant to Section 8.01 hereof; or

         (h) the Issuer or the Trust Estate is required to register as an
"investment company" pursuant to the Investment Company Act of 1940, as amended.

         SECTION 6.02 ACCELERATION OF STATED MATURITY DATE; RESCISSION AND
                      ANNULMENT.

         If an Event of Default shall have occurred and be continuing, then, and
in every such case, the Indenture Trustee shall, at the direction of the
Controlling Party, declare the principal of all the Notes to be immediately due
and payable, by notice given in writing to the Issuer (and to the Indenture
Trustee if given by Noteholders); provided, that the Note Insurer, if the Note
Insurer is the Controlling Party, shall not declare the Outstanding Principal
Amount of all of the Notes immediately due and payable unless the Note Insurer
shall have endorsed the Note Insurance Policies to provide coverage for any
shortfall in the payment of accelerated principal and any interest due on the
Outstanding Notes on the date established for redemption thereof pursuant to
such acceleration, and upon any such declaration, such principal shall become
immediately due and payable without any presentment, demand, protest or other
notice of any kind (except such notices as shall be expressly required by the
provisions of this Indenture), all of which are hereby expressly waived.

         At any time after such a declaration of acceleration has been made, but
before any Sale of the Trust Estate has been made or a judgment or decree for
payment of the money due has been obtained by the Indenture Trustee as provided
hereinafter in this Article, the Controlling Party, by written notice to the
Issuer and the Indenture Trustee, may rescind and annul such declaration and its
consequences (except that in the case of a payment default on the Notes, the
consent of all the Noteholders shall be required to rescind and annul such a
declaration and its consequences) if:

         (b) all Events of Default have been cured or waived as provided in
Section 6.15 hereof, other than the nonpayment of the principal on any of the

right consequent thereon.

         SECTION 6.03 COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY
                      INDENTURE TRUSTEE.

         The Issuer covenants that if an Event of Default shall have occurred
and be continuing and any of the Notes have been declared due and payable and
such declaration has not been rescinded and annulled, the Issuer shall, upon
demand of the Indenture Trustee and at the direction of the Controlling Party,
pay to the Indenture Trustee, for the benefit of the Holders of the Notes and
the Note Insurer, the whole amount then due and payable on the Notes for
principal and interest, with interest upon the overdue principal at

                                       39
<PAGE>   44

the rate borne by the Notes and, 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 Indenture
Trustee, the Note Insurer and their respective agents and counsel.

         If the Issuer fails to pay such amount forthwith upon such demand, the
Indenture Trustee, in its own name and as Indenture Trustee of an express trust
shall, at the direction of the Controlling Party, institute Proceedings for the
collection of the sums so due and unpaid, and prosecute such Proceeding to
judgment or final decree, and enforce the same against the Issuer and collect
the monies adjudged or decreed to be payable in the manner provided by law out
of the property of the Issuer, wherever situated.

         If an Event of Default shall have occurred and be continuing, the
Indenture Trustee shall, at the direction of the Controlling Party proceed, to
protect and enforce its rights and the rights of such Controlling Party by such
appropriate Proceedings as the Indenture Trustee, at the direction of the
Controlling Party, shall deem most effective to protect and enforce any such
rights, whether for the specific enforcement of any covenant or agreement in
this Indenture or in aid of the exercise of any power granted herein, or to
enforce any other proper remedy.

         SECTION 6.04 REMEDIES.

         If an Event of Default shall have occurred and be continuing, the

and payable on the Notes or under this Indenture, whether by declaration or
otherwise, enforce any judgment obtained, and collect from the Issuer the monies
adjudged due;

         (b) take possession of and sell the Trust Estate securing the Notes or
any portion thereof or rights or interest therein, at one or more Sales called
and conducted in any manner permitted by law;

         (c) institute any Proceedings from time to time for the complete or
partial foreclosure of the lien created by this Indenture with respect to the
Trust Estate securing the Notes;

         (d) during the continuance of a default under a Contract, exercise any

applicable law and take any other appropriate action to protect and enforce the
rights and remedies of the Indenture Trustee, the Note Insurer or the Holders of
the Notes hereunder; and

         (f) institute proceedings against the Note Insurer for the collection
of any amounts then due and payable under any Note Insurance Policy, whether by
declaration or otherwise, enforce any judgment obtained, and collect from the
Note Insurer the monies adjudged due;

provided, that without the consent of the Note Insurer, or, if a Note Insurer
Default has occurred and is continuing, all the Holders of Outstanding Notes,
the Indenture Trustee may not sell or otherwise liquidate any portion of the
Trust Estate unless the proceeds of such Sale or liquidation distributable to
the Noteholders are sufficient to discharge in full the amounts then due and
unpaid upon the Notes for principal and interest together with all amounts owed
to the Note Insurer under the Note Insurance Agreements.

         SECTION 6.05 OPTIONAL PRESERVATION OF TRUST ESTATE.

         If (i) an Event of Default shall have occurred and be continuing with
respect to the Notes and (ii) no Notes have been declared due and payable, or
such declaration and its consequences have been annulled and rescinded, the
Indenture Trustee shall, at the direction of the Controlling Party, elect, by
giving written notice of such election to the Issuer, to take possession of and
retain the Trust Estate securing the Notes intact, collect or cause the
collection of the proceeds thereof and make and apply all payments and deposits
and maintain all accounts in respect of such Notes in accordance with the
provisions of Article Twelve of this Indenture. If the Indenture Trustee is
unable to or is stayed from giving such notice to the Issuer for any reason
whatsoever, such election shall be effective as of the time of such
determination or request, as the case may be, notwithstanding any failure to
give such notice, and the Indenture Trustee shall give such notice upon the
removal or cure of such inability or stay (but shall have no obligation to
effect such removal or cure). Any such election may be rescinded with respect to
any portion of the Trust Estate securing the Notes remaining at the time of such
rescission by written notice to the Indenture Trustee and the Issuer from the
Controlling Party.

         SECTION 6.06 INDENTURE TRUSTEE MAY FILE PROOFS OF CLAIM.

insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment,
composition or other judicial Proceeding relating to the Issuer or any other
obligor upon any of the Notes or the property of the Issuer or of such other
obligor or their creditors, the Indenture Trustee (irrespective of whether the
principal of any of the Notes shall then be due and payable as therein expressed
or by declaration or otherwise and irrespective of whether the Indenture Trustee
shall have made any demand on the Issuer for the payment of overdue principal or
interest) shall be entitled and empowered, to intervene in such proceeding or
otherwise,

         (a) to file and prove a claim for the whole amount of principal and
interest owing and unpaid in respect of the Notes issued hereunder and to file
such other papers or documents as may be necessary or advisable in order to have
the claims of the Indenture Trustee (including any claim for the reasonable
compensation, expenses, disbursements and advances of the Indenture Trustee, its
agents and counsel and any other amounts due the Indenture Trustee under Section
7.07 hereof) and of the Note Insurer and the Noteholders allowed in such
judicial Proceeding, and

         (b) to collect and receive any monies 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 judicial Proceeding is hereby authorized by the
Note Insurer and each Noteholder to make such payments to the Indenture Trustee,
and in the event that the Indenture Trustee shall consent to the making of such
payments directly to the Note Insurer or the Noteholders, to pay to the
Indenture Trustee any amount due to it for the reasonable compensation,
expenses, disbursements and advances of the Indenture Trustee, its agents and
counsel, and any other amounts due the Indenture Trustee under Section 7.07
hereof.

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

         (a) In all Proceedings brought by the Indenture Trustee (and also any
Proceedings involving the interpretation of any provision of this Indenture to
which the Indenture Trustee shall be a party), the Indenture Trustee shall be
held to represent all of the Noteholders, and it shall not be necessary to make
any Noteholder a party to any such Proceedings.

         (b) All rights of actions and claims under this Indenture or any of the
Notes may be prosecuted and enforced by the Indenture Trustee without the
possession of any of the Notes or the production thereof in any Proceeding
relating thereto, and any such Proceedings instituted by the Indenture Trustee
shall be brought in its own name as Indenture Trustee of an express trust, and
any recovery whether by judgment, settlement or otherwise shall, after provision
for the payment of the reasonable compensation, expenses, disbursements and
advances of the Indenture Trustee, its agents and counsel, be for the Note
Insurer and the ratable benefit of the Holders of the Notes.

         SECTION 6.08 APPLICATION OF MONEY COLLECTED FOLLOWING AN EVENT OF
                      DEFAULT.

requirement of presentment, provided that each Noteholder shall surrender its
Note promptly following payment in full thereof; provided that if there are

Notes based on the applicable pro rata share; provided further, that proceeds of
a claim under a Note Insurance Policy shall be used only to pay interest and
principal on the applicable Series in the manner set forth in clauses Fifth and

judicial or otherwise, with respect to this Indenture, or for the appointment of
a receiver or trustee, or for any other remedy hereunder for so long as a Note
Insurer Default has not occurred, and if a Note Insurer Default has occurred,
unless

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

         (b) the Majority Holders shall have made written request to the
Indenture Trustee to institute Proceedings in respect of such Event of Default
in its own name as Indenture Trustee hereunder;

         (c) such Holder or Holders have offered to the Indenture Trustee

in compliance with such request;

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

         (e) no direction inconsistent with such written request has been given
to the Indenture Trustee during such 60-day period by the Majority Holders; it
being understood and intended that no one or more Holders of Notes shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other
Holders of Notes, or to obtain or to seek to obtain priority or preference over
any other Holders or to enforce any right under this

                                       43
<PAGE>   48

Indenture, except in the manner herein provided and for the equal and ratable
benefit of all the Holders of Notes.

         SECTION 6.10 UNCONDITIONAL RIGHT OF NOTEHOLDERS TO RECEIVE PRINCIPAL

enforcement of any such payment, and such right shall not be impaired without
the consent of such Holder.

         SECTION 6.11 RESTORATION OF RIGHTS AND REMEDIES.

         If the Indenture Trustee, the Note Insurer or any Noteholder has
instituted any Proceeding to enforce any right or remedy under this Indenture

been determined adversely to the Indenture Trustee, the Note Insurer or to such
Noteholder, then, and in every case, the Issuer, the Indenture Trustee, the Note
Insurer and the Noteholders shall, subject to any determination in such
Proceeding, be restored severally and respectively to their former positions

Note Insurer and the Noteholders shall continue as though no such Proceeding had
been instituted.

         SECTION 6.12 RIGHTS AND REMEDIES CUMULATIVE.

         Except as otherwise provided with respect to the replacement or payment
of mutilated, destroyed, lost or stolen Notes in the last paragraph of Section
2.07 hereof, no right or remedy herein conferred upon or reserved to the
Indenture Trustee, the Note Insurer or to the Noteholders is intended to be
exclusive of any other right or remedy, and every right and remedy shall, to the
extent permitted by law, be cumulative and in addition to every other right and
remedy given hereunder or now or hereafter existing at law or in equity or
otherwise. The assertion or employment of any right or remedy hereunder, or
otherwise, shall not prevent the concurrent assertion or employment of any other
appropriate right or remedy.

         SECTION 6.13 DELAY OR OMISSION; NOT WAIVER.

         No delay or omission of the Indenture Trustee, the Note Insurer or of
any Holder of any Note 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 any acquiescence therein. Every right and remedy given
by this Article Six or by law to the Indenture Trustee, the Note Insurer or to
the Noteholders may be exercised from time to time, and as often as may be
deemed expedient, by the Indenture Trustee, the Note Insurer or by the
Noteholders, as the case may be, subject in each case, however, to the right of
the Controlling Party to control any such right and remedy except as provided in
Section 6.14 hereof.

         SECTION 6.14 CONTROL BY NOTEHOLDERS.

         The Controlling Party shall have the right to direct the time, method
and place of conducting any Proceeding for any remedy available to the Indenture
Trustee or exercising any trust or power conferred on the Indenture Trustee;
provided that:

                                       44
<PAGE>   49

expressly provides for approval by a greater percentage of Outstanding Principal
Amount of all Notes;

         (b) any direction to the Indenture Trustee by the Noteholders to
undertake a private sale of the Trust Estate shall be by the Holders of all
Outstanding Notes, unless the condition set forth in Section 6.18(b)(ii) hereof
is met;

         (c) the Indenture Trustee may take any other action deemed proper by
the Indenture Trustee which is not inconsistent with such direction; provided
that, subject to Section 7.01 hereof, the Indenture Trustee need not take any
action which a Responsible Officer or Officers of the Indenture Trustee in good
faith determines might involve it in personal liability or be unjustly
prejudicial to the Noteholders not consenting; and

         (d) the Indenture Trustee has been furnished reasonable indemnity
against costs, expenses and liabilities which it might incur in connection
therewith as provided in Section 7.01(f) hereof.

         SECTION 6.15 WAIVER OF CERTAIN EVENTS BY LESS THAN ALL NOTEHOLDERS.

waive any past Default, Event of Default or Trigger Event hereunder and its
consequences, except:

         (a) a Default described in Sections 6.01(a), (b), (d), (e) or (f)
hereof, or

         (b) in respect of a covenant or provision hereof which under Article
Nine hereof cannot be modified or amended without the consent of the Holder of
each Outstanding Note affected.

         Upon any such waiver, such Default, Event of Default or Trigger Event
shall cease to exist, and any Event of Default or other consequence 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,
Event of Default or Trigger Event or impair any right consequent thereon.

         SECTION 6.16 UNDERTAKING FOR COSTS.

         All parties to this Indenture agree, and each Holder of any Note by its
acceptance of such Note shall be deemed to have agreed, that any court may in
its discretion require, in any suit for the enforcement of any right or remedy
under this Indenture, or in any suit against the Indenture Trustee for any
action taken, suffered or omitted by it as Indenture Trustee, the filing by any
party litigant in such suit of an undertaking to pay the costs of such suit, and
that such court may in its discretion assess reasonable costs, including
reasonable attorneys' fees, against any party litigant in such suit, having due
regard to the merits and good faith of the claims or defenses made by such party
litigant; but the provisions of this Section 6.16 shall not apply to any suit

or take the benefit or advantage of, any stay or extension law wherever enacted,
now or at any time hereafter in force, which may affect the covenants 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 shall not hinder, delay or impede the execution of

unimpaired until the entire Trust Estate securing the Notes shall have been sold
or all amounts payable on the Notes and under this Indenture with respect
thereto shall have been paid. The Indenture Trustee may from time to time
postpone any Sale by public announcement made at the time and place of such
Sale.

         (b) To the extent permitted by applicable law, the Indenture Trustee
shall not, in any private Sale, sell to a third party (i) the Trust Estate

         occurred the Holders of all Outstanding Notes, consents in writing to
         or directs the Indenture Trustee to make such Sale; or

thereof, and in lieu of paying cash therefor, any Noteholder may make settlement

Holder or other amounts owing to such Holder secured by this Indenture, that
portion of the net proceeds of such Sale to which such Holder would be entitled,
after deducting the reasonable costs, charges and expenses incurred by the
Indenture Trustee, the Note Insurer or the Noteholders in connection with such
Sale. The Notes need not be produced in order to complete any such Sale, or in
order for the net proceeds of such Sale to be credited against the Notes. The
Indenture Trustee, the Note Insurer or the Noteholders may hold, lease, operate,
manage or otherwise deal with any property so acquired in any manner permitted
by law.

         (d) The Indenture Trustee shall execute and deliver an appropriate
instrument of conveyance transferring its interest in any portion of the Trust

precedent or see to the application of any monies.

judgment upon any portion of the Trust Estate or upon any of the assets of the
Issuer.

         statements and the correctness of the opinions expressed therein, upon
         certificates or opinions furnished to the Indenture Trustee and
         conforming to the requirements of this Indenture; but in the case of
         any such certificates or opinions, which by any provision hereof are

Trustee as provided in subsection (e) below shall have occurred and be
continuing, the Indenture Trustee shall exercise such of the rights and powers
vested in it by this Indenture, and shall use the same degree of care and skill
in its exercise, as a reasonable person would exercise or use under the
circumstances in the conduct of his or her own affairs.

         (c) No provision of this Indenture shall be construed to relieve the
Indenture Trustee from liability for its own negligent action, its own negligent
failure to act, or its own willful misconduct or bad faith, except that:

                  (i) this subsection (c) shall not be construed to limit the
         effect of subsection (a) of this Section;

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

                  (iii) the Indenture Trustee shall not be liable with respect
         to any action taken or omitted to be taken by it in good faith in
         accordance with the direction of the Controlling Party or the Holders
         of Notes representing such percentage of Outstanding Principal Amount
         as may be required by the terms hereof, in accordance with Section 6.14
         hereof relating to the time, method and place of conducting any
         Proceeding for any remedy available to the Indenture Trustee, or
         exercising any trust or power conferred upon the Indenture Trustee,
         under this Indenture, the Contract Acquisition Agreement or the
         Servicing Agreement; and

                  (iv) no provision of this Indenture shall require the
         Indenture Trustee to expend or risk its own funds or otherwise incur
         any financial liability in the performance of any of its duties
         hereunder, or in the exercise of any of its rights or powers, if it
         shall have reasonable grounds for

                                       48
<PAGE>   53

         believing that repayment of such funds or adequate indemnity against
         such risk or liability is not reasonably assured to it, provided that
         nothing contained in this Indenture shall excuse the Indenture Trustee
         for failure to perform its duties as Indenture Trustee under this
         Indenture.

         (d) Whether or not therein expressly so provided, every provision of
this Indenture relating to the conduct or affecting the liability of or
affording protection to the Indenture Trustee shall be subject to the provisions
of this Section 7.01.

         (e) For all purposes under this Indenture, the Indenture Trustee shall
not be deemed to have notice of any Event of Default described in Section
6.01(e) or 6.01(f) hereof or any Default described in Section 6.01(d) hereof or
of any Trigger Event unless a Responsible Officer assigned to and working in the
Indenture Trustee's corporate trust department has actual knowledge thereof or
unless written notice of any event which is in fact such an Event of Default,
Default or Trigger Event is received by the Indenture Trustee at the Corporate
Trust Office, and such notice references any of the Notes generally, the Issuer,
the Trust Estate or this Indenture.

         (f) The Indenture Trustee shall be under no obligation to institute any
suit, or to take any remedial proceeding under this Indenture, or to enter any
appearance or in any way defend in any suit in which it may be made defendant,
or to take any steps in the execution of the trusts hereby created or in the
enforcement of any rights and powers hereunder until it shall be indemnified to
its satisfaction against any and all costs and expenses, outlays and counsel
fees and other reasonable disbursements and against all liability, except
liability that is adjudicated, in connection with any action so taken.

         (g) Notwithstanding any extinguishment of all right, title and interest
of the Issuer in and to the Trust Estate following an Event of Default and a
consequent declaration of acceleration of the maturity of any of the Notes,
whether such extinguishment occurs through a Sale of the Trust Estate to another
person or the acquisition of the Trust Estate by the Indenture Trustee, the
rights of the Noteholders shall continue to be governed by the terms of this
Indenture.

         (h) Notwithstanding anything to the contrary contained herein, the
provisions of subsections (e) through (g), inclusive, of this Section 7.01 shall
be subject to the provisions of subsections (a) through (c), inclusive, of this
Section 7.01.

         (i) The Indenture Trustee shall provide the reports and accountings as
required pursuant to Section 12.04 hereof.

         SECTION 7.02 NOTICE OF DEFAULT AND OTHER EVENTS.

         Promptly after the occurrence of any Default, Trigger Event or Note
Insurer Default known to the Indenture Trustee (within the meaning of Section
7.01(e) hereof) which is continuing, within one Business Day of obtaining such
knowledge, the Indenture Trustee shall transmit by telephonic or telegraphic
communication confirmed by mail to the Note Insurer and by mail to all Holders
of Notes, as their names and addresses appear on the Note Register, notice of
such Default, Trigger Event or Note Insurer Default known to the Indenture
Trustee.

         SECTION 7.07 COMPENSATION AND REIMBURSEMENT.

         The Issuer agrees:

         (a) to pay the Indenture Trustee monthly its fee for all services

any applicable laws by the Issuer as a result of the transactions contemplated
by this Indenture), including, but not limited to, any judgment, award,
settlement, reasonable attorneys' fees and other expenses incurred in connection
with the defense of any actual or threatened action, proceeding or claim;
provided, that the Issuer shall not indemnify the Indenture Trustee if such
loss, liability, expense, damage or injury is due to the Indenture Trustee's
gross negligence or willful misconduct, willful misfeasance or bad faith in the
performance of duties. Any indemnification pursuant to this Section shall only
be payable from the assets of the Issuer and shall not be payable from the
assets of the Trust Estate. The provisions of this indemnity shall run directly
to and be enforceable by an injured Person subject to the limitations hereof and
this indemnification agreement shall survive the termination of this Indenture.

         SECTION 7.08 CORPORATE TRUSTEE REQUIRED; ELIGIBILITY.

         There shall at all times be a trustee hereunder which shall be a
corporation or association organized and doing business under the laws of the
United States of America or of any State, authorized under such laws to exercise
corporate trust powers, having a combined capital and surplus of at least
$100,000,000 (or a lesser amount with the approval of the Controlling Party and
the Rating Agencies), subject to supervision or examination by federal or state
authority and having an office within the United States of America, not
affiliated (within the meaning of Rule 3a-7 under the Investment Company Act)
with the Issuer or any other Person involved in the organization or operation of
the Issuer, and which shall have a commercial paper or other short-term rating
of the highest short term rating categories by each of the Rating Agencies, or
otherwise acceptable to each of the Rating Agencies and the Controlling Party.
If such corporation publishes reports of condition at least annually, pursuant
to law or to the requirements of the aforesaid supervising or examining
authority, then for the purposes of this Section, the combined capital and
surplus of such corporation shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. If at
any time the Indenture Trustee shall cease to be eligible in accordance with the
provisions of this Section, it shall resign immediately in the manner and with
the effect hereinafter specified in this Article.

<PAGE>   57

         SECTION 7.09 RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

         (a) No resignation or removal of the Indenture Trustee and no
appointment of a successor Indenture Trustee pursuant to this Article shall
become effective until the acceptance of appointment by the successor Indenture
Trustee under Section 7.10 hereof.

         (b) The Indenture Trustee may resign at any time by giving 30 days
written notice thereof to the Issuer, the Note Insurer and to each Noteholder.
If an instrument of acceptance by a successor Indenture Trustee shall not have
been delivered to the Indenture Trustee within 30 days after the giving of such
notice of resignation, the resigning Indenture Trustee may petition any court of
competent jurisdiction for the appointment of a successor Indenture Trustee.
Such court may thereupon, after such notice, if any, as it may deem proper and
may prescribe, appoint a successor Indenture Trustee.

         (c) The Indenture Trustee may be removed by the Controlling Party at
any time if one of the following events have occurred:

                  (i) the Indenture Trustee shall cease to be eligible under
         Section 7.08 hereof and shall fail to resign after written request
         therefor by the Issuer, the Note Insurer or any Noteholder, or

                  (ii) the Indenture Trustee shall become incapable of acting or
         shall be adjudged a bankrupt or insolvent or a receiver of the
         Indenture Trustee or of its property shall be appointed or any public
         officer shall take charge or control of the Indenture Trustee or of its
         property or affairs for the purpose of rehabilitation, conservation or
         liquidation, or

                  (iii) the Indenture Trustee has failed to perform its duties
         in this Indenture or has breached any representation or warranty made
         in this Indenture.

         (d) If the Indenture Trustee shall resign, be removed or become
incapable of acting, or if a vacancy shall occur in the office of the Indenture
Trustee for any cause with respect to any of the Notes, the Issuer by a Board
Resolution, shall promptly appoint a successor Indenture Trustee satisfactory to
the Controlling Party. If no successor Indenture Trustee shall have been so
appointed by the Issuer within 30 days of notice of removal or resignation and
shall have accepted appointment in the manner hereinafter provided, then the
Controlling Party may appoint a successor Indenture Trustee. If the Note Insurer
is the Controlling Party and has failed to appoint a successor Indenture Trustee
within 90 days after succeeding to the right to so appoint a successor Indenture
Trustee, then the Majority Holders may petition any court of competent
jurisdiction for the appointment of a successor Indenture Trustee with respect
to the Notes.

         (e) The Issuer shall give notice in the manner provided in Section
13.04 hereof of each resignation and each removal of the Indenture Trustee and
each appointment of a successor Indenture Trustee with respect to the Notes to
the Noteholders and the Rating Agencies. Each notice shall include the name of
the successor Indenture Trustee and the address of its Corporate Trust Office.

         SECTION 7.10 ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

         Every successor Indenture Trustee appointed hereunder shall execute,
acknowledge and deliver to the Issuer and the retiring Indenture Trustee an
instrument accepting such appointment, and thereupon the resignation or removal
of the retiring Indenture Trustee shall become effective and such successor
Indenture Trustee, without any further act, deed or conveyance, shall become
vested with all the rights, powers, trusts and duties of the retiring Indenture
Trustee but, on request of the Issuer or the successor Indenture Trustee, such
retiring Indenture Trustee shall, upon payment of its reasonable out-of-pocket
costs and expenses, execute and deliver an instrument transferring to such
successor Indenture Trustee all the rights, powers and trusts of the retiring
Indenture Trustee, and shall duly assign, transfer and deliver to such successor
Indenture Trustee all property and money held by such retiring Indenture Trustee
hereunder, subject nevertheless to its lien, if any, provided for in Section
7.07 hereof. Upon request of any such successor Indenture Trustee, the Issuer
shall execute any and all instruments for more fully and certainly vesting in
and confirming to such successor Indenture Trustee all such rights, powers and
trusts.

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

         SECTION 7.11 MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO
                      BUSINESS OF INDENTURE TRUSTEE.

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

         SECTION 7.12 CO-INDENTURE TRUSTEES AND SEPARATE INDENTURE TRUSTEES.

         At any time or times, for the purpose of meeting the legal requirements
of any jurisdiction in which any of the Trust Estate may at the time be located,
the Issuer, the Controlling Party and the Indenture Trustee shall have power to
appoint, and, upon the written request of the Indenture Trustee, the Controlling
Party or of the Holders representing at least 25% in Outstanding Principal
Amount of all Notes, the Issuer shall for such purpose join with the Indenture
Trustee in the execution, delivery and performance of all instruments and
agreements necessary or proper to appoint, one or more Persons approved by the
Indenture Trustee and meeting the requirements of Section 7.08 hereof, either to
act as co-Indenture Trustee, jointly with the Indenture Trustee of all or any
part of such Trust Estate, or to act as separate Indenture Trustee of any such
property, in either case with such powers as may be provided in the instrument
of appointment, and to vest in such Person or Persons in the capacity aforesaid,
any property, title, right or power deemed necessary or desirable, subject to
the other provisions of this Section. If the Issuer does not join in such
appointment within 15 days after the receipt by it of a request so to do, or in
case an Event of Default shall have occurred and be continuing, the Indenture
Trustee alone shall have power to make such appointment.

                                       54
<PAGE>   59

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

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

         (a) the Notes shall be authenticated and delivered by, and all rights,
powers, duties and obligations under this Indenture in respect of the custody of
securities, cash and other personal property held by, or required to be
deposited or pledged with, the Indenture Trustee under this Indenture, shall be
exercised solely by the Indenture Trustee;

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

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

         (d) no co-Indenture Trustee or separate Indenture Trustee hereunder
shall be personally liable by reason of any act or omission of the Indenture
Trustee or any other such Indenture Trustee hereunder nor shall the Indenture
Trustee be liable by reason of any act or omission of any co-Indenture Trustee
or separate Indenture Trustee selected by the Indenture Trustee with due care or
appointed in accordance with directions to the Indenture Trustee pursuant to
Section 6.14; and

         (e) any Act of Noteholders delivered to the Indenture Trustee shall be
deemed to have been delivered to each such co-Indenture Trustee and separate
Indenture Trustee.

         SECTION 7.13 RIGHTS WITH RESPECT TO THE SERVICER.

         The Indenture Trustee's rights and obligations with respect to the

         SECTION 7.14 APPOINTMENT OF AUTHENTICATING AGENT.

         The Indenture Trustee may appoint an Authenticating Agent or Agents
with respect to the Notes which shall be authorized to act on behalf of the
Indenture Trustee to authenticate Notes issued upon original issue or upon
exchange, registration of transfer or pursuant to Section 2.05 hereof, and Notes
so authenticated shall be entitled to the benefits of this Indenture and shall
be valid and obligatory for all purposes as if authenticated by the Indenture
Trustee hereunder. Wherever reference is made in this Indenture to the
authentication and delivery of Notes by the Indenture Trustee or the Indenture
Trustee's certificate of authentication or the delivery of Notes to the
Indenture Trustee for authentication, such reference shall be deemed to include
authentication and delivery on behalf of the Indenture Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Indenture Trustee by an Authenticating Agent and delivery of the Notes to
the Authenticating Agent on behalf of the Indenture Trustee. Each Authenticating
Agent shall be acceptable to the Issuer, the Note Insurer and the Noteholders
and shall at all times be a corporation having a combined capital and surplus of
not less than the equivalent of $50,000,000 and subject to supervision or
examination by Federal or state authority or the equivalent foreign authority,
in the case of an Authenticating Agent who is not organized and doing business
under the laws of the United States of America, any state thereof or the
District of Columbia. If such Authenticating Agent publishes reports of
condition at least annually, pursuant to law or to the requirements of said
supervising or examining authority, then for the purposes of this Section, the
combined capital and surplus of such Authenticating Agent shall be deemed to be
its combined capital and surplus as set forth in its most recent report of
condition so published. If at any time an Authenticating Agent shall cease to be
eligible in accordance with the provisions of this Section, such Authenticating
Agent shall resign immediately in the manner and with the effect specified in
this Section.

         Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency or
corporate trust business of such Authenticating Agent, shall continue to be an
Authenticating Agent without the execution or filing of any paper or any further
act on the part of the Indenture Trustee or such Authenticating Agent; provided,
that such corporation shall be otherwise eligible under this Section.

         An Authenticating Agent may resign at any time by giving written notice
thereof to the Indenture Trustee, the Note Insurer and to the Issuer. The
Indenture Trustee may at any time terminate the agency of an Authenticating
Agent by giving written notice thereof to such Authenticating Agent, the Note
Insurer and to the Issuer. Upon receiving such a notice of resignation or upon
such a termination, or in case at any time such Authenticating Agent shall cease
to be eligible in accordance with the provisions of this Section, the Indenture
Trustee may appoint a successor Authenticating Agent which shall be acceptable
to the Issuer and the Controlling Party and shall mail written notice of such
appointment by first-class mail, postage prepaid, to all Holders of Notes, if
any, with respect to which such Authenticating Agent will serve, as their names
and addresses appear in the Note Register. Any successor Authenticating Agent
upon acceptance of its appointment hereunder shall become vested with all the
rights, powers and duties of its predecessor hereunder, with like effect as if
originally named as an Authenticating Agent. No successor Authenticating Agent
shall be appointed unless eligible under the provisions of this Section.

         The Indenture Trustee may pay to each Authenticating Agent from time to
time reasonable compensation for its services under this Section and the
Indenture Trustee shall be entitled to be reimbursed for such payments, subject
to the provisions of Section 7.07 hereof.

         SECTION 7.15 INDENTURE TRUSTEE TO HOLD CONTRACTS.

         The Indenture Trustee hereby acknowledges receipt of (subject to any
exceptions as may be noted by the Indenture Trustee to the Servicer and the
Controlling Party pursuant to Section 4.05 hereof) and shall hold each Contract,
together with any documents relating thereto that may from time to time be
delivered to the Indenture Trustee, until such time as such Contract is released
from the lien of this Indenture pursuant to the terms of this Indenture.

         Except as set forth in Section 4.05 hereof, the Indenture Trustee shall
be under no duty or obligation to inspect, review or examine the Contracts and
other documents to determine that the same are genuine, enforceable or
appropriate for the represented purpose or that they have actually been recorded
or that they are other than what they purport to be on their face.

         SECTION 7.16 MONEY FOR NOTE PAYMENTS TO BE HELD IN TRUST.

         The Indenture Trustee shall execute and deliver, and if there is any
Paying Agent other than the Indenture Trustee, the Issuer shall cause each
Paying Agent other than the Indenture Trustee to execute and deliver to the
Indenture Trustee and the Controlling Party an instrument in which such Paying
Agent shall agree with the Indenture Trustee that, subject to the provisions of
this Section, such Paying Agent shall:

         (a) hold all sums held by it for the payment of principal or interest
on Notes in trust for the benefit of the Noteholders entitled thereto and the
Note Insurer until such sums shall be paid to such Persons or otherwise disposed
of as herein provided;

         (b) give the Indenture Trustee, the Note Insurer and the Noteholders
notice of any Default by the Issuer (or any other obligor upon the Notes) in the
making of any payment of principal or interest; and

         (c) at any time during the continuance of any such Default, upon the
written request of the Indenture Trustee, forthwith pay to the Indenture Trustee
all sums so held in trust by such Paying Agent.

         The Issuer may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Issuer Order direct any Paying Agent to pay, to the

                                       57
<PAGE>   62

Indenture Trustee all sums held in trust by such Paying Agent, such sums to be
held by the Indenture Trustee upon the same trusts as those upon which such sums
were held by such Paying Agent; and, upon such payment by any Paying Agent to
the Indenture Trustee, such Paying Agent shall be released from all further
liability with respect to such money.

         Any money deposited with the Indenture Trustee or any Paying Agent in
trust for the payment of the principal or interest on any Note and remaining
unclaimed for three years after such principal or interest has become due and
payable shall be paid to the Issuer on Issuer Request or to the Note Insurer if
such payment had been made by the Note Insurer; and the Holder of such Note
shall thereafter, as an unsecured general creditor, and subject to any
applicable statute of limitations, look only to the Issuer for payment thereof,
and all liability of the Indenture Trustee, such Paying Agent or the Note
Insurer with respect to such trust money or the related Note, shall thereupon
cease; provided, that the Indenture Trustee or such Paying Agent, before being
required to make any such repayment, may at the expense of the Issuer cause to
be published once, in a newspaper published in the English language, customarily
published on each Business Day and of general circulation in the city in which
the Corporate Trust Office is located, notice that such money remains unclaimed
and that, after a date specified therein, which shall not be less than 30 days
from the date of such publication, any unclaimed balance of such money then
remaining shall be repaid to the Issuer; and provided further, that any amounts
held that are proceeds of a claim made under a Note Insurance Policy shall be
returned to the Note Insurer, and the Noteholders shall look only to the Note
Insurer for such payments. The Indenture Trustee may also adopt and employ, at
the expense of the Issuer, any other reasonable means of notification of such
repayment (including, but not limited to, mailing notice of such repayment to
Noteholders whose right to or interest in monies due and payable but not claimed
is determinable from the records of any Paying Agent, at the last address as
shown on the Note Register for each such Noteholder).

                          THE NOTE INSURANCE POLICIES

         SECTION 8.01 PAYMENTS UNDER THE NOTE INSURANCE POLICIES.

         With respect to any applicable Series, if on the close of business on
the fourth Business Day prior to any Payment Date, the funds on deposit in the
Collection Account and available to be distributed on such Payment Date pursuant
to Section 12.02(d) hereof (after taking into account any transfers from the
Cash Collateral Account in accordance with Section 12.03 and any amounts payable
pursuant to Section 12.02(d)(i) through (iv) hereof) are not sufficient to make
the payment of interest due on the Outstanding Notes of such Series on such
Payment Date in accordance with Section 12.02(d)(v) hereof, the Indenture
Trustee shall, no later than 10:00 a.m. (Central Time), on the third Business
Day immediately preceding such Payment Date make a claim under the applicable
Note Insurance Policy in an amount equal to such insufficiency (the "Interest
Deficiency Draw Amount"). In addition, with respect to any Series, if on the
close of business on the fourth Business Day immediately prior to the related
Stated Maturity Date the funds on deposit in the Collection Account (after
taking into account any transfers from the Cash Collateral Account in accordance
with Section 12.03 and any amounts payable pursuant to Section 12.02(d)(i)
through (v) hereof) are not sufficient to pay the entire Outstanding Principal
Amount of all Notes of the applicable Series (after giving effect to the
application of funds available to pay the Pro Rata Share of the Principal
Distribution Amount of each Outstanding Series in accordance with Section
12.02(d)(vi) hereof), the Indenture Trustee shall, no later than 10:00 a.m.
(Central Time), on the third Business Day immediately preceding such Payment
Date, make a claim under the applicable Note Insurance Policy in an amount equal
to such insufficiency (the "Note Principal Balance Deficiency"). Proceeds of
claims on the Note Insurance Policies shall be deposited in the Collection
Account or the Redemption Account, as applicable, by 11:00 a.m. (Central Time)
on the later of (i) the second Business Day after receipt by the Note Insurer of
notice of such claim and (ii) the Business Day immediately preceding such
Payment Date and used solely to pay amounts due in respect of interest on the
applicable Notes on each Payment Date prior to the Stated Maturity Date and
principal of and interest on the applicable Notes at the Stated Maturity Date.

         In addition, on any day that the Indenture Trustee has actual knowledge
or receives notice that any amount previously paid to a Noteholder has been
subsequently recovered from such Noteholder pursuant to a final order of a court
of competent jurisdiction that such payment constitutes an avoidable preference
within the meaning of any applicable bankruptcy law to such Noteholder (a
"Preference Claim"), the Indenture Trustee shall make a claim within one
Business Day upon the relevant Note Insurance Policy for the full amount of such
Preference Claim in accordance with the terms of such Note Insurance Policy. Any
proceeds of any such Preference Claim received by the Indenture Trustee shall be
paid to the related Noteholders.

time to time, may enter into one or more amendments or indentures supplemental
hereto, in form satisfactory to the Indenture Trustee, for any of the following
purposes, provided that any such amendment or supplement, as evidenced by an

material adverse affect on any Noteholder:

         (a) to correct or amplify the description of any property at any time

unto the Indenture Trustee any property subject or required to be subjected to
the lien of this Indenture, or to subject to the lien of this Indenture
additional property; or

         (b) to evidence the succession of another Person to the Issuer, and the
assumption by such successor of the covenants of the Issuer herein and in the

         (c) to add to the covenants of the Issuer, for the benefit of the Note
Insurer or the Holders of all Notes, or to surrender any right or power herein
conferred upon the Issuer; or

         (d) to convey, transfer, assign, mortgage or pledge any property to or
with the Indenture Trustee; or

         (e) to cure any ambiguity, to correct or supplement any provision

Series then Outstanding, to amend the definition of "Collateralization
Percentage," or "Trigger Event"; or

         (j) as may be necessary to effectuate the issuance of any additional
Series of Notes in accordance with the terms of this Indenture and the related
Supplement; provided that any such amendment does not modify this Indenture in a
manner described in paragraphs (a)(i) through (a)(viii) of Section 9.02 hereof.

<PAGE>   65

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

         Promptly after the execution by the Issuer, the Servicer, the Back-up
Servicer and the Indenture Trustee of any amendment or supplemental indenture,
and the consent thereto by the Note Insurer, pursuant to this Section, the
Issuer shall mail to the Rating Agencies and each Noteholder a copy of such
amendment or supplemental indenture.

         SECTION 9.02 AMENDMENTS OR SUPPLEMENTAL INDENTURES WITH CONSENT OF
                      NOTEHOLDERS.

         (a) With the prior written consent of (i) the Note Insurer, unless a

Indenture Trustee and written notice thereof delivered to the Rating Agencies,
the Issuer, the Servicer, the Back-up Servicer and the Indenture Trustee may
enter into amendments 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 Notes under this Indenture. Notwithstanding the foregoing, no
such amendment or supplemental indenture shall, without the consent of the
Holders of each Outstanding Note:

                  (i) change the Stated Maturity Date of any Note or the due
         date of any installment of principal of, or any installment of interest
         on, any Note, or reduce the principal amount thereof or the Note
         Interest Rate or change any place of payment where, or the coin or
         currency in which, any Note or the interest thereon is payable, or
         impair the right to institute suit for the enforcement of any such
         payment; or

                  (ii) reduce the percentage in Outstanding Principal Amount of
         Notes, the consent of the Holders of which is required for any such
         amendment or supplemental indenture, or the consent of the Holders of
         which is required for any waiver of compliance with certain provisions
         of this Indenture or Events of Default or their consequences; or

                  (iii) impair or adversely affect the Trust Estate except as

         Outstanding Note affected thereby; or

<PAGE>   66

                  (vii) 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 or terminate the lien of this Indenture on any property at
         any time subject hereto or deprive the Holder of any Note of the
         security afforded by the lien of this Indenture; or

                  (viii) modify any of Sections 4.02, 6.01(a) or (b), 6.02,
         6.03, 6.18, or 12.02(d) hereof.

         (b) The Indenture Trustee is hereby authorized to join in the execution
of any supplemental indenture pursuant to clause (a) above and to make any
further appropriate agreements and stipulations that may be therein contained,
but the Indenture Trustee shall not be obligated to enter into any such
supplemental indenture that affects the Indenture Trustee's own rights, duties,
liabilities or immunities under this Indenture. Promptly after the execution by
the Issuer, the Servicer, the Back-up Servicer and the Indenture Trustee of any
supplemental indenture pursuant to this Section, the Issuer shall mail to the
Holders of the Notes, the Note Insurer and the Rating Agencies a copy of such
supplemental indenture.

         SECTION 9.03 EXECUTION OF AMENDMENTS AND SUPPLEMENTAL INDENTURES.

         In executing any amendment or supplemental indenture permitted by this
Article or the modifications thereby of the trusts created by this Indenture,
the Indenture Trustee shall be entitled to receive upon request, and (subject to
Section 7.01 hereof) shall be fully protected in relying in good faith upon, an
Opinion of Counsel reasonably acceptable to the Indenture Trustee stating that
the execution of such amendment or supplemental indenture is authorized or
permitted by this Indenture. The Indenture Trustee may, but shall not be
obligated to, enter into any such amendment or supplemental indenture which
affects the Indenture Trustee's own duties or immunities under this Indenture or
otherwise.

         SECTION 9.04 EFFECT OF AMENDMENTS AND SUPPLEMENTAL INDENTURES.

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

         SECTION 9.05 REFERENCE IN NOTES TO AMENDMENTS AND SUPPLEMENTAL
                      INDENTURES.

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

         SECTION 9.06 CERTAIN AMENDMENTS. If any party to this Indenture is
unable to sign any amendment due to its dissolution, winding up or comparable
circumstances, then the consent of the Noteholders representing at least 51% in
Outstanding Principal Amount of all Notes of all Series shall be sufficient to
allow an amendment that otherwise meets the requirements of this Article Nine to
become effective without such party's signature; provided, however, that no such
amendment shall impose on the

<PAGE>   67

party that is unable to provide a signature any obligation or liability in
excess of what is then currently imposed hereunder prior to such amendment.

                                  ARTICLE TEN

                              REDEMPTION OF NOTES

         SECTION 10.01 REDEMPTION AT THE OPTION OF THE ISSUER; ELECTION TO
                       REDEEM.

         Except as may be otherwise specified in the related Supplement, the
Issuer shall have the option to redeem all of the Outstanding Notes of any
Series of Notes at any time after the Outstanding Principal Amount of such
Series of Notes is less than 10% of the original Outstanding Principal Amount of
such Series of Notes as of the related Delivery Date, in each case at the
applicable Redemption Price plus any fees due hereunder and all amounts due to
the Note Insurer under the related Note Insurance Agreement. With respect to any
such permitted redemption, the Note Insurer shall have the same option to redeem
any such Series of Notes in the absence of the exercise thereof by the Issuer.

         The Issuer or the Note Insurer, as the case may be, shall set the
Redemption Date and the Redemption Record Date for a Series of Notes and give
notice thereof to the Indenture Trustee pursuant to Section 10.02 hereof.

         Installments of interest and principal that are due regarding a Series
of Notes on or prior to the related Redemption Date shall continue to be payable
to the Holders of such Notes called for redemption as of the relevant Record
Dates according to their terms and the provisions of Section 2.08 hereof. The
election of the Issuer or the Note Insurer to redeem any Notes pursuant to this
Section shall be evidenced by a Board Resolution or written notice from the Note
Insurer, respectively, directing the Indenture Trustee to make the payment of
the Redemption Price on all of the Notes to be redeemed from monies deposited
with the Indenture Trustee pursuant to Section 10.02 hereof.

         SECTION 10.02 NOTICE TO INDENTURE TRUSTEE; DEPOSIT OF REDEMPTION PRICE.

         In the case of any redemption pursuant to Section 10.01 hereof, the
Issuer or the Note Insurer, as applicable, shall, at least 15 days prior to the
related Redemption Date, notify the Indenture Trustee and the Holders of the
Series of Notes to be redeemed of such Redemption Date and shall deposit into
the Redemption Account on such notification date an amount equal to the
Redemption Price of all Notes to be redeemed on such Redemption Date plus any
fees due hereunder and all amounts due to the Note Insurer under the related
Note Insurance Agreement.

         SECTION 10.03 NOTICE OF REDEMPTION BY THE ISSUER.

         Upon receipt of such notice and such deposit set forth in Section 10.02
above, the Indenture Trustee shall provide notice of redemption pursuant to
Section 10.01 hereof by first-class mail, postage prepaid, mailed no later than
the Business Day following the date on which such deposit was made, to each
Holder of Notes whose Notes are to be redeemed, at his address in the Note
Register.

         All notices of redemption shall state:

         (a)      the applicable Redemption Date;

         (b)      the applicable Redemption Price; and

<PAGE>   69

         (c) that on such Redemption Date, the Redemption Price will become due
and payable upon each such Note in the related Series, and that interest thereon
shall cease to accrue on such date.

         Notice of redemption of a Series of Notes shall be given by the
Indenture Trustee in the name and at the expense of the Issuer or the Note
Insurer, as applicable. Failure to give notice of redemption, or any defect
therein, to any Holder of any Note selected for redemption shall not impair or
affect the validity of the redemption of any other Note.

         SECTION 10.04 NOTES PAYABLE ON REDEMPTION DATE.

         Notice of redemption having been given as provided in Section 10.03
hereof, the Series of Notes to be redeemed shall, on the applicable Redemption
Date, become due and payable at the Redemption Price and on such Redemption Date
(unless the Issuer or the Note Insurer, as applicable, shall default in the
payment of the Redemption Price) such Notes shall cease to bear interest. The
Holders of such Notes shall be paid the Redemption Price by the Paying Agent on
behalf of the Issuer; provided, that installments of principal and interest that
are due regarding such Series of Notes on or prior to such Redemption Date shall
be payable to the Holders of such Notes registered as such on the relevant
Record Dates according to their terms and the provisions of Section 2.08 hereof.

         If the Holders of any Note called for redemption shall not be so paid,
the principal and premium, if any, on such Series of Notes shall, until paid,
bear interest from the applicable Redemption Date at the related Note Interest
Rate.

         SECTION 10.05 RELEASE OF SERIES CONTRACTS.

         In connection with any redemption permitted under this Article Ten, the
Issuer or the Note Insurer, as the case may be, shall be permitted to obtain a
release of the related Series Contracts, (a) to the extent provided in Section
4.06(b) hereof and (b) so long as the applicable Redemption Price shall have
been deposited into the Redemption Account as required by Section 10.02, and the
Insurance Policy has been terminated with respect to such Series or the Note
Insurer otherwise consents to such release.

                                 ARTICLE ELEVEN

                    REPRESENTATIONS, WARRANTIES AND COVENANTS

         SECTION 11.01 REPRESENTATIONS AND WARRANTIES.

         The Issuer hereby makes the following representations and warranties
for the benefit of the Indenture Trustee, the Note Insurer and the Noteholders
on which the Indenture Trustee relies in accepting the Trust Estate in trust and
in authenticating the Notes. Such representations and warranties are made as of
the Initial Delivery Date and, except as specifically provided herein, each
additional Delivery Date, and shall survive the Grant of the Trust Estate to the
Indenture Trustee.

         (a) ORGANIZATION AND GOOD STANDING. The Issuer is a corporation duly
organized, validly existing and in good standing under the laws of its State of
incorporation and each other State where the nature of its business requires it
to qualify, except to the extent that the failure to so qualify would not in the
aggregate materially adversely affect the Trust Estate or the ability of the
Issuer to perform its obligations under the Transaction Documents. The Issuer
has not operated under any other names and does not have any trade names,
fictitious names or "doing business as" names. The Issuer has no subsidiaries;

         (b) AUTHORIZATION. The Issuer has the power, authority and legal right
to execute, deliver and perform under the terms of the Transaction Documents and
the execution, delivery and performance of the Transaction Documents have been
duly authorized by the Issuer by all necessary corporate action;

         (c) BINDING OBLIGATION. Assuming the due authorization, execution and
delivery by each other party thereto, each of (i) this Indenture, (ii) the
applicable Note Insurance Agreement, (iii) the Servicing Agreement, (iv) the
Contract Acquisition Agreement, (v) the Notes then Outstanding and (vi) the Note
Purchase Agreement constitutes a legal, valid and binding obligation of the
Issuer, enforceable against the Issuer in accordance with its terms except (A)
as such enforcement may be subject to or limited by applicable bankruptcy,
conservatorship, insolvency, reorganization, moratorium or other similar laws
(whether statutory, regulatory or decisional) now or hereafter in effect
relating to creditors' rights generally and (B) the remedy of specific
performance and injunctive and other forms of equitable relief may be subject to
certain equitable defenses and to the discretion of the court before which any
proceeding therefor may be brought, whether a proceeding at law or in equity;

         (d) NO VIOLATION. The consummation of the transactions contemplated by
the terms of the Transaction Documents will not conflict with, result in any
breach of any of the terms and provisions of or constitute (with or without
notice, lapse of time or both) a default under the organizational documents or
bylaws of the Issuer, or any indenture, agreement, mortgage, deed of trust or
other instrument to which the Issuer is a party or by which it is bound, or in
the creation or imposition of any Lien upon any of its properties pursuant to
the terms of such indenture, agreement, mortgage, deed of trust or other such
instrument, other than any Lien created or imposed pursuant to the terms of the
Transaction Documents, or violate any law or, any material order, rule or
regulation applicable to the Issuer of any court or of any federal or state

Indenture Trustee to open and maintain a trust account at the Corporate Trust
Office (the "Redemption Account") in the name of the Indenture Trustee for the

         SECTION 12.03 CASH COLLATERAL ACCOUNT.

         (a) Prior to the Initial Delivery Date, the Issuer shall cause the
Indenture Trustee to open and maintain a trust account at the Corporate Trust
Office (the "Cash Collateral Account") in the name of the Indenture Trustee for
the benefit of the relevant Noteholders and the Note Insurer, for the receipt of
(i) the Initial Cash Collateral Account Deposit required to be made with respect
to a Series of Notes and (ii) deposits pursuant to Section 12.02(d)(vii). Monies
received in the Cash Collateral Account shall be invested at the written
direction of the Issuer in Eligible Investments during the term of this
Indenture, and any income or other gain realized from such investment, shall be
held by the Indenture Trustee in the Cash Collateral Account as part of the
Trust Estate as security for the Notes subject to disbursement and

<PAGE>   80

withdrawal as herein provided. Monies shall be subject to withdrawal in
accordance with Section 12.03(d) hereof.

         (b) Upon Issuer Order, all or a portion of the Cash Collateral Account
shall be invested and reinvested at the Issuer's written direction in one or
more Eligible Investments. In the absence of an Issuer Order, the Indenture
Trustee shall invest funds in the Cash Collateral Account in Eligible
Investments described in clause (g) of the definition thereof. Eligible
Investments shall be made in the name of the Indenture Trustee for the benefit
of the relevant Noteholders and the Note Insurer. All income or other gain from
such investments shall be credited to such Cash Collateral Account and any loss
resulting from such investments shall be charged to such Cash Collateral
Account; provided, that the Issuer shall make or cause to be made on any
Determination Date a deposit to the Cash Collateral Account to the extent of any
losses therein caused as a result of the Issuer's investment instructions. No
Eligible Investment shall mature later than the Business Day preceding the next
following Determination Date and shall not be sold or disposed of prior to its
maturity. The Indenture Trustee shall provide to the Servicer and the Note
Insurer monthly written confirmation of such investments, describing the
Eligible Investments in which such amounts have been invested. Any funds not so
invested must be insured by the Federal Deposit Insurance Corporation.

         (c) If any amounts invested as provided in Section 12.03(b) hereof
shall be needed for disbursement from the Cash Collateral Account as set forth
in Section 12.03(d) hereof, the Indenture Trustee shall cause such investments
of such Cash Collateral Account to be sold or otherwise converted to cash to the
credit of such Cash Collateral Account. The Indenture Trustee shall not be
liable for any investment loss resulting from investment of money in the Cash
Collateral Account in any Eligible Investment in accordance with the terms
hereof (other than in its capacity as obligor under any Eligible Investment).

         (d) Disbursements from the Cash Collateral Account shall be made, to
the extent funds therefor are available, only as follows:

                  (i) in the event that the amount in the Collection Account at
         10:00 a.m. Central Time on the Determination Date immediately preceding
         any Payment Date is less than the sum of (1) the amounts required to be
         paid from the Collection Account on such Payment Date pursuant to
         clauses (i) through (v) of Section 12.02(d) hereof plus (2) the
         Principal Distribution Amount determined in accordance with clauses
         (a)(i) and (b) of the definition thereof, the Indenture Trustee shall
         withdraw funds from the Cash Collateral Account on or prior to 4:00
         p.m. Central Time on such Determination Date to the extent necessary to
         make such payments on such Payment Date and deposit such funds into the
         Collection Account;

                  (ii) subject to subparagraph (iii) of this Section 12.03(d),
         in the event that on any Payment Date the balance in the Cash
         Collateral Account equals an amount greater than the Cash Collateral
         Account Required Balance (after giving effect to the distributions
         required under Section 12.03(d)(i) and Section 12.02(d)(i) through
         (vii) hereof on such Payment Date), the Indenture Trustee shall
         withdraw funds in the Cash Collateral Account in such amount so that
         the remaining amount in the Cash Collateral Account after such
         withdrawal will equal the Cash Collateral Account Required Balance, and
         deposit such funds into the Collection Account for disbursement in
         accordance with the provisions of Section 12.02(d) hereof; and

                  (iii) in the event that on any Payment Date a Trigger Event
         has occurred, the Indenture Trustee shall withdraw all funds from the
         Cash Collateral Account and deposit such

<PAGE>   81
         funds into the Collection Account for disbursement in accordance with
         the provisions of Section 12.02(d) hereof.

         SECTION 12.04 REPORTS BY INDENTURE TRUSTEE TO THE NOTE INSURER AND
                       NOTEHOLDERS.

         (a) On each Payment Date, the Indenture Trustee shall account to each
Holder of Notes on which payments of principal and interest are then being made
the amount which represents principal and the amount which represents interest,
and shall contemporaneously advise the Issuer and the Note Insurer of all such
payments. The Indenture Trustee shall satisfy its obligations under this Section
12.04 by delivering the Monthly Servicer's Report to each Holder of the Notes,
the Note Insurer, the Issuer, the Rating Agencies and the Placement Agent. On or
before the 15th day prior to any Final Payment Date the Indenture Trustee shall
provide notice to the Note Insurer, the Rating Agencies and the Holders of the
applicable Series of Notes of the Final Payment Date for such Notes. Such notice
shall include (1) a statement that interest shall cease to accrue as of the last
day preceding the date on which the Final Payment Date occurs, and (2) shall
specify the place or places at which the Notes of such Series are to be
surrendered following payment thereof.

         (b) At least annually, or as otherwise required by law, the Indenture
Trustee shall distribute to Noteholders any information returns or other tax
information or statements as are required by applicable tax law to be
distributed to the Noteholders. The Servicer shall prepare or cause to be
prepared all such information for distribution by the Indenture Trustee to the
Noteholders.

                        PROVISIONS OF GENERAL APPLICATION

         SECTION 13.01 GENERAL PROVISIONS.

         All of the provisions of this Article shall apply to this Indenture, as
supplemented by each Supplement.

         SECTION 13.02 ACTS OF NOTEHOLDERS.

         (a) Any request, demand, authorization, direction, notice, consent,
waiver or other action provided by this Indenture to be given or taken by
Noteholders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Noteholders in person or by an agent
duly appointed in writing; and, except as herein otherwise expressly provided,
such action shall become effective when such instrument or instruments are
delivered to the Indenture Trustee, and, where it is hereby expressly required,
to the Issuer. Such instrument or instruments (and the action embodied therein
and evidenced thereby) are herein sometimes referred to as the "Act" of the
Noteholders 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 7.01 hereof)
conclusive in favor of the Indenture Trustee and the Issuer, if made in the
manner provided in this Section 13.02.

         (b) The fact and date of the execution by any Person of any such
instrument or writing may be proved in any manner which the Indenture Trustee
deems sufficient.

         (c) The ownership of Notes shall be proved by the Note Register.

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

         SECTION 13.03 NOTICES, ETC., TO INDENTURE TRUSTEE, THE NOTE INSURER,
                       ISSUER AND SERVICER.

         Any request, demand, authorization, direction, notice, consent, waiver
or Act of Noteholders or other document provided or permitted by this Indenture
to be made upon, given or furnished to, or filed with any party hereto shall be
sufficient for every purpose hereunder if in writing and telecopied or mailed,
first-class postage prepaid and addressed to the appropriate address below:

         (a) to the Indenture Trustee at Sixth Street and Marquette Avenue, MAC
N9311-161, Minneapolis, Minnesota 55479, Facsimile: (612) 667-3464, or at any
other address previously furnished in writing to the Issuer, the Note Insurer,
the Noteholders and the Servicer; or

         (b) to the Note Insurer at Ambac Assurance Corporation, One State
Street Plaza, New York, New York 10004, Facsimile: (212) 208-3547, or at any
other address previously furnished in writing by the Note Insurer to the
Indenture Trustee, the Noteholders, the Servicer and the Issuer; or

<PAGE>   83

         (c) to the Issuer at 950 Winter Street, Suite 4100B, Waltham,
Massachusetts 02451, Facsimile: (781) 890-1368, or at any other address
previously furnished in writing to the Indenture Trustee, the Note Insurer, the
Noteholders and the Servicer by the Issuer; or

         (d) to the Servicer at 950 Winter Street, Suite 4100, Waltham,
Massachusetts 02451, Facsimile: (781) 890-1368, or at any other address
previously furnished in writing to the Indenture Trustee, the Note Insurer, the
Noteholders and the Issuer.

         (e) to each of (i) S & P, Attention: Asset Backed Surveillance Group,
55 Water Street, New York, New York 10041, Facsimile: (212) 438-2646 and (ii)
Moody's, 99 Church Street, New York, NY 10007, Facsimile: (212) 553-7820.

         SECTION 13.04 NOTICES TO NOTEHOLDERS; WAIVER.

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

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

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

         SECTION 13.05 EFFECT OF HEADINGS AND TABLE OF CONTENTS.

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

         SECTION 13.06 SUCCESSORS AND ASSIGNS.

         All covenants and agreements in this Indenture by the Issuer shall bind
its successors and assigns, whether so expressed or not. There shall be no
assignment hereof, except in accordance with the provisions of Section 7.10
hereof.

<PAGE>   84

         SECTION 13.07 SEPARABILITY.

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

         SECTION 13.08 BENEFITS OF INDENTURE.

         Nothing in this Indenture or in the Notes, express or implied, shall
give to any Person, other than the parties hereto, the Noteholders, and any
Paying Agent which may be appointed pursuant to the provisions hereof, and any
of their successors hereunder, any benefit or any legal or equitable right,
remedy or claim under this Indenture or under the Notes.

         SECTION 13.09 GOVERNING LAW.

         THE INDENTURE AND EACH NOTE SHALL BE CONSTRUED IN ACCORDANCE WITH AND
GOVERNED BY THE INTERNAL LAWS OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS
MADE AND TO BE PERFORMED THEREIN, WITHOUT REGARD TO THE CONFLICT OF LAWS
PROVISIONS OF ANY STATE THAT WOULD RESULT IN THE APPLICATION OF THE LAWS OF A
STATE OTHER THAN NEW YORK.

         SECTION 13.10 COUNTERPARTS.

         The Indenture may be executed in any number of counterparts, each of
which so executed shall be deemed to be an original, but all such counterparts
shall together constitute but one and the same instrument. Delivery of an
executed counterpart of a signature page to this Indenture by telecopier shall
be as effective as delivery of manually executed counterpart of this Indenture.

         SECTION 13.11 COMPLIANCE CERTIFICATES AND OPINIONS.

         Upon any application, order or request by the Issuer or the Servicer to
the Indenture Trustee to take any action under any provision of this Indenture
for which a specific request is required under this Indenture, the Issuer or the
Servicer, as applicable, shall furnish to the Indenture Trustee an Officer's
Certificate of the Issuer or the Servicer, as applicable, stating that all
conditions precedent, if any, provided for in this Indenture relating to the
proposed action have been complied with, except that in the case of any such
application or request as to which the furnishing of a different certificate is
specifically required by any provision of this Indenture relating to such
particular application or request, no additional certificate need be furnished.

         Every certificate or opinion with respect to compliance with a
condition or covenant provided for in this Indenture shall include:

         (a) a statement that each individual signing such certificate or
opinion has read or has caused to be read such covenant or condition and the
definitions herein relating thereto;

         (b) a brief statement as to the nature and scope of the examination or

individual 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

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

         (a) The parties hereto hereby irrevocably submit to the non-exclusive
jurisdiction of the United States District Court for the Southern District of
New York and any court in the State of New York Located in the City and County
of New York, and any appellate court from any thereof, in any action, suit or
proceeding brought against or by it in connection with this Agreement or for
recognition or enforcement of any judgment relating thereto, and the parties
hereto hereby irrevocably and unconditionally agree that all claims in respect
of any such action or proceeding may be heard or determined in such New York
state court or, to the extent permitted by law, in such federal court. The
parties agree that a final nonappealable judgment in any such action, suit or
proceeding shall be conclusive and may be enforced in other jurisdictions by
suit on the judgment or in any other manner provided by law. To the extent
permitted by applicable law, the parties hereby waive and agree not to assert by
way of motion, as a defense or otherwise in any such suit, action or proceeding,
any claim that it is not personally subject to the jurisdiction of such courts,
that the suit, action or proceeding is brought in an inconvenient forum, that
the venue of the suit, action or proceeding is improper or that the related
documents or the subject matter thereof may not be litigated in or by such
courts.

         (b) To the extent permitted by applicable law, the parties shall not
seek and hereby waive the right to any review of the judgment of any such court
by any court of any other jurisdiction which may be called upon to grant an
enforcement of such judgment.

         (c) Service on any party hereto may be made by mailing or delivering
copies of the summons and complaint and other process which may be served in any
suit, action or proceeding to such party at its address listed in herein or in
the other Transaction Documents. Such address may be changed by the applicable
party or parties by written notice to each of the other parties hereto.

         (d) Nothing contained in this Agreement shall limit or affect any
party's right to serve process in any other manner permitted by law or to start
legal proceedings relating to its rights under other agreements or against any
other party or its properties in the courts of any jurisdiction.
